    Determine the reasons for inappropriate prescription of antibiotics and identify opportunities to improve prescription of these drugs in pediatric patients hospitalized in intermediate and intensive care units. A prospective, descriptive longitudinal study was conducted of pediatric patients in intermediate and intensive care units who received parenteral administration of antibiotics, with the exception of newborns, burn unit patients, and surgical prophylaxis patients. A univariate analysis and multiple logistic regression were performed. A total of 376 patients with a median of age of 50 months were studied (interquartile range [IQR] 14.5-127 months). Out of the total patients studied, 75% had one or more underlying conditions. A total of 40.6% of these patients had an oncologic pathology and 33.5% had neurological conditions. The remaining 25.9% had other underlying conditions. Antibiotic treatment was inappropriate in 35.6% of the patients studied (N = 134). In 73 (54.4%) of the 134 cases, inappropriate use was due to the type of antibiotic prescribed, the dose administered, or the treatment period. The 61 (45.5%) remaining cases did not require antibiotic treatment. In the multivariate analysis, the risk factors for inappropriate use of antibiotics were: administration of ceftriaxone OR 2 (95% CI, 1.3-3.7; P = 0.02); acute lower respiratory tract infection OR 1.8 (95% CI, 1.1-3.3; P < 0.04); onset of fever of unknown origin in hospital inpatients OR 5.55 (95% CI, 2.5-12; P < 0.0001); and febrile neutropenia OR 0.3 (95% CI, 0.1-0.7; P = 0.009). Inappropriate use of antibiotics was less common in the clinical conditions that were well-characterized. Prescribing practices that could be improved were identified through the preparation and circulation of guidelines for antibiotic use in hospital inpatients.

    The purpose of this study was to assess dental antibiotic prescribing trends over time, to quantify the number and types of antibiotics dentists prescribe inappropriately, and to estimate the excess health care costs of inappropriate antibiotic prescribing with the use of a large cohort of general dentists in the United States. We used a quasi-Poisson regression model to analyze antibiotic prescriptions trends by general dentists between January 1, 2013, and December 31, 2015, with the use of data from Express Scripts Holding Company, a large pharmacy benefits manager. We evaluated antibiotic duration and appropriateness for general dentists. Appropriateness was evaluated by reviewing the antibiotic prescribed and the duration of the prescription. Overall, the number and rate of antibiotic prescriptions prescribed by general dentists remained stable in our cohort. During the 3-year study period, approximately 14% of antibiotic prescriptions were deemed inappropriate, based on the antibiotic prescribed, antibiotic treatment duration, or both indicators. The quasi-Poisson regression model, which adjusted for number of beneficiaries covered, revealed a small but statistically significant decrease in the monthly rate of inappropriate antibiotic prescriptions by 0.32% (95% confidence interval, 0.14% to 0.50%; P = .001). Overall antibiotic prescribing practices among general dentists in this cohort remained stable over time. The rate of inappropriate antibiotic prescriptions by general dentists decreased slightly over time. From these authors' definition of appropriate antibiotic prescription choice and duration, inappropriate antibiotic prescriptions are common (14% of all antibiotic prescriptions) among general dentists. Further analyses with the use of chart review, administrative data sets, or other approaches are needed to better evaluate antibiotic prescribing practices among dentists.

    Adherence to antimicrobial guidelines for empiric antibiotic prescribing in community-acquired pneumonia (CAP) has been reported to be worryingly low. We conducted a review of empiric antibiotic prescribing for sixty consecutive adult patients admitted to the Mercy University Hospital with a diagnosis of CAP. When analysed against local antimicrobial guidelines, guideline concordant empiric antibiotics were given in only 48% of cases, lower than the average rate in comparable studies. Concordance was 100% in cases where the CURB-65 pneumonia severity assessment score, on which the guidelines are based, was documented in the medical notes. The use of excessively broad spectrum and inappropriate antibiotics is a notable problem. This study supports the theory that lack of knowledge regarding pneumonia severity assessment tools and unfamiliarity with therapeutic guidelines are key barriers to guideline adherence, which remains a significant problem despite increased focus on antimicrobial stewardship programs in Ireland

    The objective of this study was to explore whether the percentage of inappropriate empirical antibiotic treatment in patients with bacteremia changed over time and to understand the factors that brought on the change. Three prospective cohorts of patients with bacteremia in three different periods (January 1st, 1988 to December 31st, 1989; May 1st, 2004 to November 30, 2004; May 1st, 2010 to April 30, 2011) were compared. Analysis was performed on a total of 811 patients. In 2010-2011, 55.9% (76/136) of patients with bacteremia received inappropriate empirical treatment, compared with 34.5% (170/493) and 33.5% (55/164) in the first and second periods, respectively, in a significant upward trend (p = 0.001). Resistance to antibiotics increased significantly during the study period. The following variables were included in the multivariate analysis assessing risk factors for inappropriate empirical treatment: study period (third period) [odds ratio, OR = 2.766 (95% confidence interval, CI, 1.655-4.625)], gender (male) [OR = 1.511 (1.014-2.253)], pathogen carrying extended-spectrum beta-lactamases [OR = 10.426 (4.688-23.187)], multidrug-resistant Acinetobacter baumannii [OR = 5.428 (2.181-13.513)], and skin/soft infections [OR = 3.23 (1.148-9.084)]. A model excluding microbiological data included: gender (male) [OR = 1.648 (1.216-2.234)], study period (third period) [OR = 2.446 (1.653-3.620)], hospital-acquired infection [OR = 1.551 (1.060-2.270)], previous use of antibiotics [OR = 1.815 (1.247-2.642)], bedridden patient [OR = 2.019 (1.114-3.658)], and diabetes mellitus [OR = 1.620 (1.154-2.274)]. We have observed a worrisome increase in the rate of inappropriate empirical treatment of bacteremia. We need tools that will allow us better prediction of the pathogen and its susceptibilities during the first hours of managing a patient suspected of a severe bacterial infection.

    Methods We performed a descriptive, retrospective study of matient medical records of those admitted to the pediatric ward from January 1 – June 30, 2009. Records were screened for patient antibiotic use, followed by qualitative evaluation using Gyssens algorithm on data from patient who received antibiotic treatment. Results We found 49.2% of subject were prescribed antibiotics. The majority of patients given antibiotics were aged 1 month - 1 year (39.3%. Antibiotic use was categorized by therapy type : empirical, prophylactic, or definitive. We found empirical therapy in 73% of cases, prophylactic in 8%, and definitive in 15%. Cefotaxime was the most common antibiotic used (25.1%, followed by ceftazidime (14% and cotrimoxazole (1%. 39.6% of subjects were given antibiotics appropriately, while 48.3% were given inappropriately. In 3.3% of patients, antibiotics were given without indication and in 8.8% there was insufficient data. Conclusions Of hospitalized patients receiving antibiotic treatment at the Departement of Child Health, Cipto Mangunkusumo Hospital, 39.6% were given antibiotic appropriately, while 48.3% were given antibiotics inappropriately. Cefotaxime was the most commonly used, as well as most inappropriately given antibiotic.

  6. Severity assessment scores to guide empirical use of antibiotics in community acquired pneumonia.

    2013-10-01

    Severity assessment scores were first developed to predict the 30 day mortality in community acquired pneumonia; however, several guidelines have extended their use to guide empirical antibiotic prescription decisions. This approach has theoretical advantages because a decrease in broad-spectrum antibiotic treatment in low-risk patients might reduce antibiotic-related side-effects, and to give broad-spectrum therapy to patients at higher risk of death is intuitive. However, evidence in support of this approach is not clear. In particular, the British Thoracic Society guidelines suggest withholding a macrolide from patients with low CURB 65 scores, despite evidence that these patients have a higher frequency of atypical pathogens than do those with a higher severity of pneumonia. Severity scores do not perform well in some groups and might overestimate disease severity in elderly people, leading to inappropriate broad-spectrum treatment to those at high risk of complications such as Clostridium difficile infection. In this Review, we discuss the evidence for antibiotic prescribing guided by severity score and suggest that more evidence of effect and implementation is needed before this approach can be universally adopted.

    Full Text Available Abstract Background There are few reports of interventions to reduce the common but irrational use of antibiotics for acute non-bloody diarrhoea amongst hospitalised children in low-income settings. We undertook a secondary analysis of data from an intervention comprising training of health workers, facilitation, supervision and face-to-face feedback, to assess whether it reduced inappropriate use of antibiotics in children with non-bloody diarrhoea and no co-morbidities requiring antibiotics, compared to a partial intervention comprising didactic training and written feedback only. This outcome was not a pre-specified end-point of the main trial. Methods Repeated cross-sectional survey data from a cluster-randomised controlled trial of an intervention to improve management of common childhood illnesses in Kenya were used to describe the prevalence of inappropriate antibiotic use in a 7-day period in children aged 2-59 months with acute non-bloody diarrhoea. Logistic regression models with random effects for hospital were then used to identify patient and clinician level factors associated with inappropriate antibiotic use and to assess the effect of the intervention. Results 9, 459 admission records of children were reviewed for this outcome. Of these, 4, 232 (44.7% were diagnosed with diarrhoea, with 130 of these being bloody (dysentery therefore requiring antibiotics. 1, 160 children had non-bloody diarrhoea and no co-morbidities requiring antibiotics-these were the focus of the analysis. 750 (64.7% of them received antibiotics inappropriately, 313 of these being in the intervention hospitals vs. 437 in the controls. The adjusted logistic regression model showed the baseline-adjusted odds of inappropriate antibiotic prescription to children admitted to the intervention hospitals was 0.30 times that in the control hospitals (95%CI 0.09-1.02.

    The purpose of this study is to determine the rate of prolonged empiric antibiotic therapy in adult ICUs in the United States. Our secondary objective is to examine the relationship between the prolonged empiric antibiotic therapy rate and certain ICU characteristics. Multicenter, prospective, observational, 72-hour snapshot study. Sixty-seven ICUs from 32 hospitals in the United States. Nine hundred ninety-eight patients admitted to the ICU between midnight on June 20, 2011, and June 21, 2011, were included in the study. None. Antibiotic orders were categorized as prophylactic, definitive, empiric, or prolonged empiric antibiotic therapy. Prolonged empiric antibiotic therapy was defined as empiric antibiotics that continued for at least 72 hours in the absence of adjudicated infection. Standard definitions from the Centers for Disease Control and Prevention were used to determine infection. Prolonged empiric antibiotic therapy rate was determined as the ratio of the total number of empiric antibiotics continued for at least 72 hours divided by the total number of empiric antibiotics. Univariate analysis of factors associated with the ICU prolonged empiric antibiotic therapy rate was conducted using Student t test. A total of 660 unique antibiotics were prescribed as empiric therapy to 364 patients. Of the empiric antibiotics, 333 of 660 (50%) were continued for at least 72 hours in instances where Centers for Disease Control and Prevention infection criteria were not met. Suspected pneumonia accounted for approximately 60% of empiric antibiotic use. The most frequently prescribed empiric antibiotics were vancomycin and piperacillin/tazobactam. ICUs that utilized invasive techniques for the diagnosis of ventilator-associated pneumonia had lower rates of prolonged empiric antibiotic therapy than those that did not, 45.1% versus 59.5% (p = 0.03). No other institutional factor was significantly associated with prolonged empiric antibiotic therapy rate. Half of all

    The aim of this review is to focus on the recent knowledge on antibiotic stewardship and empiric antibiotic treatment in cirrhotic patients. The application of antimicrobial stewardship (AMS) rules appears to be the most appropriate strategy to globally manage cirrhotic patients with infectious complications: indeed they represent a unique way to provide both early diagnosis and appropriate therapy in order to avoid not only antibiotic over-prescription but, more importantly, selection and spread of antimicrobial resistance. Moreover, cirrhotic patients must be considered "frail" and susceptible to healthcare associated infections: applying AMS policies would assure a cost reduction and thus contribute to the improvement of public health strategies.

    Despite the known clonal distribution of antibiotic resistance in many bacteria, empiric (pre-culture) antibiotic selection still relies heavily on species-level cumulative antibiograms, resulting in overuse of broad-spectrum agents and excessive antibiotic/pathogen mismatch. Urinary tract infections (UTIs), which account for a large share of antibiotic use, are caused predominantly by Escherichia coli, a highly clonal pathogen. In an observational clinical cohort study of urgent care patients with suspected UTI, we assessed the potential for E. coli clonal-level antibiograms to improve empiric antibiotic selection. A novel PCR-based clonotyping assay was applied to fresh urine samples to rapidly detect E. coli and the urine strain's clonotype. Based on a database of clonotype-specific antibiograms, the acceptability of various antibiotics for empiric therapy was inferred using a 20%, 10%, and 30% allowed resistance threshold. The test's performance characteristics and possible effects on prescribing were assessed. The rapid test identified E. coli clonotypes directly in patients' urine within 25-35 minutes, with high specificity and sensitivity compared to culture. Antibiotic selection based on a clonotype-specific antibiogram could reduce the relative likelihood of antibiotic/pathogen mismatch by ≥ 60%. Compared to observed prescribing patterns, clonal diagnostics-guided antibiotic selection could safely double the use of trimethoprim/sulfamethoxazole and minimize fluoroquinolone use. In summary, a rapid clonotyping test showed promise for improving empiric antibiotic prescribing for E. coli UTI, including reversing preferential use of fluoroquinolones over trimethoprim/sulfamethoxazole. The clonal diagnostics approach merges epidemiologic surveillance, antimicrobial stewardship, and molecular diagnostics to bring evidence-based medicine directly to the point of care.

    We aimed to construct widely useable summary measures of the net impact of antibiotic resistance on empiric therapy. Summary measures are needed to communicate the importance of resistance, plan and evaluate interventions, and direct policy and investment. As an example, we retrospectively summarised the 2011 cumulative antibiogram from a Toronto academic intensive care unit. We developed two complementary indices to summarise the clinical impact of antibiotic resistance and drug availability on empiric therapy. The Empiric Coverage Index (ECI) measures susceptibility of common bacterial infections to available empiric antibiotics as a percentage. The Empiric Options Index (EOI) varies from 0 to 'the number of treatment options available', and measures the empiric value of the current stock of antibiotics as a depletable resource. The indices account for drug availability and the relative clinical importance of pathogens. We demonstrate meaning and use by examining the potential impact of new drugs and threatening bacterial strains. In our intensive care unit coverage of device-associated infections measured by the ECI remains high (98%), but 37-44% of treatment potential measured by the EOI has been lost. Without reserved drugs, the ECI is 86-88%. New cephalosporin/β-lactamase inhibitor combinations could increase the EOI, but no single drug can compensate for losses. Increasing methicillin-resistant Staphylococcus aureus (MRSA) prevalence would have little overall impact (ECI=98%, EOI=4.8-5.2) because many Gram-positives are already resistant to β-lactams. Aminoglycoside resistance, however, could have substantial clinical impact because they are among the few drugs that provide coverage of Gram-negative infections (ECI=97%, EOI=3.8-4.5). Our proposed indices summarise the local impact of antibiotic resistance on empiric coverage (ECI) and available empiric treatment options (EOI) using readily available data. Policymakers and drug developers can use the

    Bacterial resistance burden has increased in the past years, mainly due to inappropriate antibiotic use. Recently it has become an urgent public health concern due to its impact on the prolongation of hospitalization, an increase of total cost of treatment and mortality associated with infectious disease. Almost half of the antimicrobial prescriptions in outpatient care visits are prescribed for acute upper respiratory infections, especially rhinosinusitis, otitis media, and pharyngotonsillitis. In this context, otorhinolaryngologists play an important role in orienting patients and non-specialists in the utilization of antibiotics rationally and properly in these infections. To review the most recent recommendations and guidelines for the use of antibiotics in acute otitis media, acute rhinosinusitis, and pharyngotonsillitis, adapted to our national reality. A literature review on PubMed database including the medical management in acute otitis media, acute rhinosinusitis, and pharyngotonsillitis, followed by a discussion with a panel of specialists. Antibiotics must be judiciously prescribed in uncomplicated acute upper respiratory tract infections. The severity of clinical presentation and the potential risks for evolution to suppurative and non-suppurative complications must be taken into 'consideration'. Periodic revisions on guidelines and recommendations for treatment of the main acute infections are necessary to orient rationale and appropriate use of antibiotics. Continuous medical education and changes in physicians' and patients' behavior are required to modify the paradigm that all upper respiratory infection needs antibiotic therapy, minimizing the consequences of its inadequate and inappropriate use.

    To assess hospital differences in empirical antibiotic use, bacterial epidemiology, and antimicrobial susceptibility for common antibiotic regimens among young infants with urinary tract infection (UTI), bacteremia, or bacterial meningitis. We reviewed medical records from infants <90 days old presenting to 8 US children's hospitals with UTI, bacteremia, or meningitis. We used the Pediatric Health Information System database to identify cases and empirical antibiotic use and medical record review to determine infection, pathogen, and antimicrobial susceptibility patterns. We compared hospital-level differences in antimicrobial use, pathogen, infection site, and antimicrobial susceptibility. We identified 470 infants with bacterial infections: 362 (77%) with UTI alone and 108 (23%) with meningitis or bacteremia. Infection type did not differ across hospitals ( P = .85). Empirical antibiotic use varied across hospitals ( P < .01), although antimicrobial susceptibility patterns for common empirical regimens were similar. A third-generation cephalosporin would have empirically treated 90% of all ages, 89% in 7- to 28-day-olds, and 91% in 29- to 89-day-olds. The addition of ampicillin would have improved coverage in only 4 cases of bacteremia and meningitis. Ampicillin plus gentamicin would have treated 95%, 89%, and 97% in these age groups, respectively. Empirical antibiotic use differed across regionally diverse US children's hospitals in infants <90 days old with UTI, bacteremia, or meningitis. Antimicrobial susceptibility to common antibiotic regimens was similar across hospitals, and adding ampicillin to a third-generation cephalosporin minimally improves coverage. Our findings support incorporating empirical antibiotic recommendations into national guidelines for infants with suspected bacterial infection.

    We sought to determine whether an emergency department (ED) pharmacist could aid in the monitoring and correction of inappropriate empiric antibiotic selection for urinary tract infections in an outpatient ED population. Urine cultures with greater than 100 000 CFU/mL bacteria from the University of Utah Emergency Department over 1 year (October 2011-Sept 2012) were identified using our electronic medical record system. Per ED protocol, an ED pharmacist reviews all cultures and performs a chart review of patient symptoms, diagnosis, and discharge antibiotics to determine whether the treatment was appropriate. A retrospective review of this process was performed to identify how often inappropriate treatment was recognized and intervened on by an ED pharmacist. Of the 180 cultures included, a total of 42 (23%) of empiric discharge treatments were considered inappropriate and required intervention. In 35 (83%) of 42 patients, the ED pharmacist was able to contact the patient and make appropriate changes; the remaining 7 patients were unable to be contacted, and no change could be made in their treatment. A chart review of all urine cultures with greater than 100 000 CFU/mL performed by an ED pharmacist helped identify inappropriate treatment in 23% of patients discharged to home with the diagnosis of urinary tract infection. Of these patients who had received inappropriate treatment, an ED pharmacist was able to intervene in 83% of cases. These data highlight the role of ED pharmacists in improving patient care after discharge. Copyright © 2016 Elsevier Inc. All rights reserved.

    Conclusions: Effective and timely treatment is required for CAP and empirical antibiotics are evidence-based and appropriate in most settings. However, better diagnostics and education to target treatment may help to prevent antibiotic resistance. Ensuring the secure financing of clean food and water, sanitation, and public health infrastructure are also required to reduce the burden of disease in children in developing countries.

    Drug resistance among gram-negative pathogens is a risk factor for inappropriate empiric treatment (IET), which in turn increases the risk for mortality. We explored the impact of carbapenem-resistant Enterobacteriaceae (CRE) on the risk of IET and of IET on outcomes in patients with Enterobacteriaceae infections. We conducted a retrospective cohort study in Premier Perspective database (2009-2013) of 175 US hospitals. We included all adult patients with community-onset culture-positive urinary tract infection (UTI), pneumonia, or sepsis as a principal diagnosis, or as a secondary diagnosis in the setting of respiratory failure, treated with antibiotics within 2 days of admission. We employed regression modeling to compute adjusted association of presence of CRE with risk of receiving IET, and of IET on hospital mortality, length of stay (LOS) and costs. Among 40,137 patients presenting to the hospital with an Enterobacteriaceae UTI, pneumonia or sepsis, 1227 (3.1%) were CRE. In both groups, the majority of the cases were UTI (51.4% CRE and 54.3% non-CRE). Those with CRE were younger (66.6+/-15.3 vs. 69.1+/-15.9 years, p pneumonia or sepsis was comparable to other national estimates. Infection with CRE was associated with a four-fold increased risk of receiving IET, which in turn increased mortality, LOS and costs.

    Full Text Available % 25-30 of women between 20-40 ages have urinary tract infection. In our country every year 5 million cases of cystitis occur. Some investigators suggest that empiric treatment for a short duration without doing culture is useful, safe and cost effective by estimating the factors and antibiotic’s sensitivity in the beginning in women whom are diagnosed as acute uncomplicated cystitis. On the other hand, a problem due to treatments of urinary tract infection has begun because of resistance producing from widespread using antibiotics for inappropriate indications. Therefore, in order to define appropriate antibiotics in urinary tract infection periodic surveillance is needed for checking local resistance condition. In this study, we aim to assess a clinical approach for antibiotic selection in empiric treatment of cystitis without doing culture or in beginning of cystitis therapy while waiting for the culture’s results."

    Delay in appropriate antibiotic therapy is associated with an increase in mortality and prolonged length of stay. Automatic dispensing machines decrease the delivery time of intravenous (IV) antibiotics to patients in the emergency department (ED). However, when IV antibiotics are not reviewed by pharmacists before being administered, patients are at risk for receiving inappropriate antibiotic therapy. The objective of this study was to determine if a difference exists in the time to administration of appropriate antibiotic therapy before and after implementation of prospective verification of antibiotics in the ED. This retrospective, institutional review board-approved preimplementation vs postimplementation study evaluated patients 18years or older who were started on IV antibiotics in the ED. Patients were excluded if pregnant, if the patient is a prisoner, if no cultures were drawn, or if the patient was transferred from an outside facility. Appropriate antibiotic therapy was based on empiric source-specific evidence-based guidelines, appropriate pharmacokinetic and pharmacodynamic properties, and microbiologic data. The primary end point was the time from ED arrival to administration of appropriate antibiotic therapy. Of the 1628 evaluated, 128 patients met the inclusion criteria (64 pre vs 64 post). Patients were aged 65.2±17.0years, with most of infections being pneumonia (44%) and urinary tract infections (18%) and most patients being noncritically ill. Time to appropriate antibiotic therapy was reduced in the postgroup vs pregroup (8.1±8.6 vs 15.2±22.8hours, respectively, P=.03). In addition, appropriate empiric antibiotics were initiated more frequently after the implementation (92% post vs 66% pre; P=.0001). There was no difference in mortality or length of stay between the 2 groups. Prompt administration of the appropriate antibiotics is imperative in patients with infections presenting to the ED.

    The 2005 American Thoracic Society/Infectious Diseases Society of America (ATS/IDSA) guidelines for hospital-acquired pneumonia (HAP), ventilator-associated pneumonia (VAP), and health care-associated pneumonia (HCAP) stress the importance of initiating prompt appropriate empiric antibiotic therapy. This study's purpose was to determine the percentage of patients with HAP, VAP, and HCAP who received guideline-based empiric antibiotic therapy and to determine the average time to receipt of an appropriate empiric regimen. A retrospective chart review of adults with HAP, VAP, or HCAP was conducted at a community hospital in suburban Birmingham, Alabama. The hospital's electronic medical record system utilized International Classification of Diseases, Ninth Revision (ICD-9) codes to identify patients diagnosed with pneumonia. The percentage of patients who received guideline-based empiric antibiotic therapy was calculated. The mean time from suspected diagnosis of pneumonia to initial administration of the final antibiotic within the empiric regimen was calculated for patients who received guideline-based therapy. Ninety-three patients met the inclusion criteria. The overall guideline adherence rate for empiric antibiotic therapy was 31.2%. The mean time to guideline-based therapy in hours:minutes was 7:47 for HAP and 28:16 for HCAP. For HAP and HCAP combined, the mean time to appropriate therapy was 21:55. Guideline adherence rates were lower and time to appropriate empiric therapy was greater for patients with HCAP compared to patients with HAP. © The Author(s) 2015.

    Antibiotic resistance is a major worldwide public health concern. In clinical settings, timely antibiotic resistance information is key for care providers as it allows appropriate targeted treatment or improved empirical treatment when the specific results of the patient are not yet available. To improve antibiotic resistance trend analysis algorithms by building a novel, fully data-driven forecasting method from the combination of trend extraction and machine learning models for enhanced biosurveillance systems. We investigate a robust model for extraction and forecasting of antibiotic resistance trends using a decade of microbiology data. Our method consists of breaking down the resistance time series into independent oscillatory components via the empirical mode decomposition technique. The resulting waveforms describing intrinsic resistance trends serve as the input for the forecasting algorithm. The algorithm applies the delay coordinate embedding theorem together with the k-nearest neighbor framework to project mappings from past events into the future dimension and estimate the resistance levels. The algorithms that decompose the resistance time series and filter out high frequency components showed statistically significant performance improvements in comparison with a benchmark random walk model. We present further qualitative use-cases of antibiotic resistance trend extraction, where empirical mode decomposition was applied to highlight the specificities of the resistance trends. The decomposition of the raw signal was found not only to yield valuable insight into the resistance evolution, but also to produce novel models of resistance forecasters with boosted prediction performance, which could be utilized as a complementary method in the analysis of antibiotic resistance trends.

    To assess the complaints of patients who were prescribed antibiotics following orodental problems and the need for antibiotics prescribed for this purpose. Examinations were carried out in the Department of Oral Diagnosis and Radiology, Ege University, Turkey. A total of 203 patients (129 females and 74 males) between 8-70 years of age (mean age 37.7 +/- 13.9). Examination and report. Frequency of unnecessary antibiotic use. Antibiotic therapy was not necessary for 151 (74.4 per cent) cases. Antibiotics were unnecessarily prescribed in 45 cases of acute irreversible pulpitis, 10 chronic apical abscess, 6 acute apical paradontitis, 7 gingivitis, 10 periodontitis, 4 epulis, 2 TMJ (temporomandibular junction) dysfunction, 2 sharp ridge of alveolar bone, 1 burning mouth syndrome and 1 recurrent aphthous stomatitis. In 108 (53.2 per cent) of the cases, the prescribed antibiotics were found to be penicillins, 102 of which were broad-spectrum. It was also determined that only 6 (7.7 per cent) of the 78 cases diagnosed as acute apical abscess were given drainage as local therapy. Principles for treating dental infections suggest that an antibiotic should only be used to supplement and not substitute for conventional surgical methods. Therefore, in cases with acute apical abscess, mechanical treatment (drainage) should be the first step. Inappropriate antibiotic use is quite widespread in dentistry. Dentists should avoid inappropriate use of antibiotics. To prevent inappropriate administration, necessary precautions need to be taken against dispensing antibiotics without prescription.

    Conflicting results have been found regarding outcomes of intensive care unit (ICU)-acquired Enterobacteriaceae bacteraemia and the potentially modifying effect of appropriate empiric antibiotic therapy. To evaluate these associations while adjusting for potential time-varying confounding using methods from the causal inference literature. Patients who stayed more than two days in two general ICUs in England between 2002 and 2006 were included in this cohort study. Marginal structural models with inverse probability weighting were used to estimate the mortality and discharge associated with Enterobacteriaceae bacteraemia and the impact of appropriate empiric antibiotic therapy on these outcomes. Among 3411 ICU admissions, 195 (5.7%) ICU-acquired Enterobacteriaceae bacteraemia cases occurred. Enterobacteriaceae bacteraemia was associated with an increased daily risk of ICU death [cause-specific hazard ratio (HR): 1.48; 95% confidence interval (CI): 1.10-1.99] and a reduced daily risk of ICU discharge (HR: 0.66; 95% CI: 0.54-0.80). Appropriate empiric antibiotic therapy did not significantly modify ICU mortality (HR: 1.08; 95% CI: 0.59-1.97) or discharge (HR: 0.91; 95% CI: 0.63-1.32). ICU-acquired Enterobacteriaceae bacteraemia was associated with an increased daily risk of ICU mortality. Furthermore, the daily discharge rate was also lower after acquiring infection, even when adjusting for time-varying confounding using appropriate methodology. No evidence was found for a beneficial modifying effect of appropriate empiric antibiotic therapy on ICU mortality and discharge. Crown Copyright © 2017. Published by Elsevier Ltd.

    Abstract Background Multiple studies estimate that inappropriate antibiotic prescribing ranges from 30–50% in hospitalized patients, but few have included pediatric patients. Pediatric studies characterizing inappropriate prescribing are needed to target and improve antimicrobial stewardship program (ASP) efforts. Methods Cross-sectional analysis of antimicrobial prescribing at 30 U.S. children’s hospitals. Participating hospitals were academic, tertiary care hospitals in the Sharing Antimicrobial Reports for Pediatric Stewardship (SHARPS) collaborative. Subjects were children 0–17 years with an active antibiotic order at 0800 on a single day during three consecutive calendar quarters (Q3 2016 – Q1 2017). Each hospital’s ASP used a standardized survey to collect data on antibiotic orders and evaluate appropriateness. Data were pooled from the three surveys. The primary outcome was the pooled estimate for the percentage of prescriptions classified as inappropriate. Secondary outcomes were pooled estimates for indication, reason for inappropriate use, and ASP review status for each antibiotic. Results Of 19,598 children hospitalized on survey days, 6,922 (35%) had ≥1 active antibiotic order. Median age of children receiving antibiotics was 3.7 years (0.5, 10.9). Figures 1 and 2 show the most common antibiotics and indications. Of all antibiotic orders, 1,514 (15%) were classified as inappropriate, and 19% of patients with antibiotic orders had at least one inappropriate order. The most common reasons for inappropriate use were bug-drug mismatch (26%), surgical prophylaxis > 24 hours (18%) and unnecessary duplicate therapy (12%). ASPs would not have routinely reviewed 50% of all inappropriate orders. An additional 22% of inappropriate orders were for antibiotics typically reviewed by ASPs, but were yet to be reviewed at the time of the survey. Conclusion Across 30 children’s hospitals, approximately 1 in 3 hospitalized children is receiving an antibiotic

    Full Text Available Objective: The purpose of this study was to evaluate the use of empirical vancomycin for patients with neutropenic fever (NF with regard to adherence to treatment guidelines. Methods: Adult patients with a diagnosis of neutropenia, who met the definition of NF as per treatment guidelines, were identified. Use of vancomycin was evaluated as part of empirical therapy and again after 72 h. Outcomes were assessed using descriptive statistics, the Chi-square or Fisher’s exact test, and univariate exact logistic regression analyses. Results: Sixty-four patients were included. Overall, inappropriate empirical vancomycin use was observed in more than 30% of patients. Of 35 patients with indications for empirical vancomycin, only 68% received it. At 72 h, appropriate vancomycin continuation, de-escalation, or discontinuation occurred in 21 of 33 patients. On univariate regression, hematological malignancy was associated with appropriate empirical vancomycin prescribing, whether initiating or withholding (odds ratio 4.0, 95% confidence interval 1.31–12.1. No variable was independently associated with inappropriate continuation at 72 h. Conclusions: There is poor guideline adherence to vancomycin prescribing as empirical therapy and at 72-h reassessment in patients with NF. Further efforts are needed to foster a more rational use of vancomycin in patients with NF. Keywords: Antibiotics, Neutropenia, Neutropenic fever, Vancomycin

    Antibiotics are often inappropriately prescribed for upper respiratory tract infections (URTIs) in developed countries. Data on the proportion of inappropriate prescriptions are lacking from the Middle East and other developing countries. Health insurance claims for all antibiotics prescribed for URTIs in the private sector in the State of Qatar between May 2014 and December 2015 were retrieved. During the study period, health insurance was limited to Qatari nationals. Topical antibiotics were excluded. Data on the prescriber's specialty, as listed with the licensing authority, were also retrieved. Diagnoses were classified as appropriate or inappropriate based on the likelihood of a bacterial etiology that may warrant antibiotic use. A total of 75 733 claims were made during the study period. Of these, 41 556 (55%) were for an appropriate indication, while 34 177 (45%) were for an inappropriate indication. The most common antibiotic classes prescribed were cephalosporins (43% of claims; 44% inappropriate), penicillins (28% of claims; 44% inappropriate), macrolides (19% of claims; 52% inappropriate), and fluoroquinolones (9% of claims; 40% inappropriate). Nearly 5% of antibiotics were prescribed in intravenous formulations. The most common prescribers were General/Family Practice physicians (53% of claims; 50% inappropriate), followed by Pediatrics (18.6% of claims; 36% inappropriate) and Internal Medicine (14.1% of claims; 44% inappropriate). There is a high rate of inappropriate antibiotic prescription for acute URTIs in the private health care sector in the State of Qatar. Further studies are needed to determine the population-based rates across the country. Interventions to decrease inappropriate use in such settings are urgently needed.

    J. Chastre

    2007-08-01

    Full Text Available Ventilator-associated pneumonia (VAP has traditionally been treated with a 14–21-day course of antibiotics. However, prolonged antibiotic therapy is associated with the emergence of multidrug-resistant strains, as well as higher toxicity and costs. In a large, randomised, controlled trial in patients with microbiologically confirmed VAP who received appropriate empirical antibiotic therapy, an 8-day antibiotic regimen was not associated with excess mortality or more episodes of recurrent pulmonary infection compared with a 15-day regimen. Amongst patients who developed recurrent infection, multidrug-resistant pathogens emerged less frequently in the group receiving 8 days of antibiotic therapy. The 8-day regimen was also not associated with excess mortality in the subgroup with VAP caused by nonfermentative Gram-negative bacilli, mostly Pseudomonas aeruginosa, although recurrent infections occurred more often. Pending confirmatory studies, an 8-day course of antibiotic therapy may be appropriate for many patients with ventilator-associated pneumonia, providing that initial antibiotic therapy is appropriate, the clinical course is favourable and extreme vigilance is maintained after stopping antibiotics. Patients whose initial treatment regimen was inappropriate, those infected with difficult-to-treat pathogens such as Pseudomonas aeruginosa, and immunocompromised patients and others at high risk for relapse are likely to require a longer duration of antibiotic therapy.

    Full Text Available Background: Pneumonia is an infection with the highest mortality rate in Indonesian hospitals. According to The American Thoracic Society and The Infectious Diseases Society of America (ATS/IDSA, empirical use of antibiotics is still effective for pneumonia treatment. Inappropriate use of antibiotics would cause negative effects such as prolonged hospitalization, a high cost of treatment, and increased antibiotic-resistant bacteria. The goal of this study was to clarify the empirical use of antibiotic conformity with a bacteria culture. Methods: This study was conducted from August to October 2013 using a descriptive retrospective method based on 116 medical records of pneumonia patients hospitalized in Melati Ward, Dr. Hasan Sadikin General Hospital Bandung during 2011–2012. The type of bacteria, conformity with antibiotics given to patients, and type of antibiotics were analyzed. The conformity of antibiotics was assessed based on the resistance test. If the results were sensitive, they would be put in the conforming group and in the non-conforming group if the results were resistant or intermediate. Data was derived with descriptive statistics, using percentage and frequency distribution, illustrated in tables and figures. Results: Based on culture results and sensitivity of antibiotic empirical therapy given, 55.17% cases were conformed. The most widely used antibiotic group was Third-generation Cephalosporin (60.34%. The most common bacterias were Klebsiella pneumonia (34.5% and Acinetobacter baumanni (13.8%. Conclusions: Most of the antibiotics given to pneumonia patients are still appropriate with results of the bacteria culture test and resistance test.

    "Nudges" that influence decision making through subtle cognitive mechanisms have been shown to be highly effective in a wide range of applications, but there have been few experiments to improve clinical practice. To investigate the use of a behavioral "nudge" based on the principle of public commitment in encouraging the judicious use of antibiotics for acute respiratory infections (ARIs). Randomized clinical trial in 5 outpatient primary care clinics. A total of 954 adults had ARI visits during the study timeframe: 449 patients were treated by clinicians randomized to the posted commitment letter (335 in the baseline period, 114 in the intervention period); 505 patients were treated by clinicians randomized to standard practice control (384 baseline, 121 intervention). The intervention consisted of displaying poster-sized commitment letters in examination rooms for 12 weeks. These letters, featuring clinician photographs and signatures, stated their commitment to avoid inappropriate antibiotic prescribing for ARIs. Antibiotic prescribing rates for antibiotic-inappropriate ARI diagnoses in baseline and intervention periods, adjusted for patient age, sex, and insurance status. Baseline rates were 43.5% and 42.8% for control and poster, respectively. During the intervention period, inappropriate prescribing rates increased to 52.7% for controls but decreased to 33.7% in the posted commitment letter condition. Controlling for baseline prescribing rates, we found that the posted commitment letter resulted in a 19.7 absolute percentage reduction in inappropriate antibiotic prescribing rate relative to control (P = .02). There was no evidence of diagnostic coding shift, and rates of appropriate antibiotic prescriptions did not diminish over time. Displaying poster-sized commitment letters in examination rooms decreased inappropriate antibiotic prescribing for ARIs. The effect of this simple, low-cost intervention is comparable in magnitude to costlier, more

    Pneumonia is a common admitting diagnosis in the intensive care unit (ICU). When aspiration is suspected, antibiotics to cover anaerobes are frequently used, but in the absence of clear risk factors, current guidelines have questioned their role. It is unknown how frequently these guidelines are followed. We conducted a single-centre observational study on practice patterns of anaerobic antibiotic use in consecutive patients admitted to the ICU with aspiration pneumonia (Asp), community-acquired pneumonia (CAP) and healthcare-associated pneumonia (HCAP). A total of 192 patients were studied (Asp: 20, HCAP: 107, CAP: 65). Overall, 59 patients received anaerobic antibiotics (Asp: 90%, HCAP: 28%, CAP 17%) but a significant proportion of these patients did not meet criteria to receive them. Inappropriate anaerobic antibiotic use was 12/20 for Asp, 27/107 for HCAP and 9/65 for CAP. Mortality probability model III at zero hours (MPM0) score and a diagnosis of Asp were predictors of receiving inappropriate anaerobic antibiotics. Receiving inappropriate anaerobic antibiotics was associated with a longer ICU length of stay (LOS; 7 days (interquartile range (IQR): 7-21) vs 4 days (IQR:2-9), P = 0.017). For patients in the ICU admitted with pneumonia, there is a high occurrence of inappropriately prescribed anaerobic antibiotics, the use of which was associated with a longer ICU LOS. © 2017 Asian Pacific Society of Respirology.

    Febrile neutropenia (FN) is the main treatment-related cause of mortality among children with cancer, as the prolonged use of broad-spectrum antibiotics can lead to antibiotic resistance in these patients. Antibiotic cycling has been reported to limit the emergence of antibiotic-resistant bacteria among adult patients. However, no studies have evaluated pediatric patients with FN. Between September 2011 and February 2014, 126 pediatric cancer patients were admitted to our center for chemotherapy and/or hematopoietic stem cell transplantation and were included in this study. Retrospective and prospective data collection were performed before and after antibiotic cycling, respectively. Between September 2011 and November 2012 (before antibiotic cycling was implemented), intravenous cefpirome was used as the empirical therapy for FN. Between December 2012 and February 2014 (after antibiotic cycling was implemented), the monthly antibiotic cycling involved intravenous piperacillin-tazobactam (PIPC/TAZ), intravenous meropenem or ciprofloxacin (CPFX), and intravenous cefepime in that order. For children aged ≥13 years, the monthly cycling involved intravenous PIPC/TAZ, and CPFX was administered. The detection rates for extended-spectrum β-lactamase producers in blood and stool culture samples decreased significantly after the implementation of antibiotic cycling (0.33/1000 patient-days vs 0/1000 patient-days, p = 0.03; 1.00/1000 patient-days vs 0/1000 patient-days, p Antibiotic cycling was associated with a decreased emergence of multidrug-resistant microbes.

    Full Text Available Abstract Background Consumers receive over 27 million antibiotic prescriptions annually in Australian primary healthcare. Hence, consumers are a key group to engage in the fight against antibiotic resistance. There is a paucity of research pertaining to consumers in the Australian healthcare environment. This study aimed to investigate the perspectives, attitudes and behaviours of Australian consumers on antibiotic use and antibiotic resistance, to inform national programs for reducing inappropriate antibiotic consumption. Method Semi-structured interviews with 32 consumers recruited via convenience and snowball sampling from a university population in South East Queensland. Interview transcripts were deductively and inductively coded. Main themes were identified using iterative thematic analysis. Results Three themes emerged from the analysis, to elucidate factors affecting antibiotic use: (a prescription type; (b consumer attitudes, behaviours, skills and knowledge; and (c consumer engagement with antibiotic resistance. Consumers held mixed views regarding the use of delayed antibiotic prescriptions, and were often not made aware of the use of repeat antibiotic prescriptions. Consumers with regular general practitioners were more likely to have shared expectations regarding minimising the use of antibiotics. Even so, advice or information mediated by general practitioners was influential with all consumers; and helped to prevent inappropriate antibiotic use behaviours. Consumers were not aware of the free Return of Unwanted Medicines service offered by pharmacies and disposed of leftover antibiotics through household waste. To engage with mitigating antibiotic resistance, consumers required specific information. Previous public health campaigns raising awareness of antibiotics were largely not seen by this sample of consumers. Conclusions Australian consumers have specific information needs regarding prescribed antibiotics to enable

    Consumers receive over 27 million antibiotic prescriptions annually in Australian primary healthcare. Hence, consumers are a key group to engage in the fight against antibiotic resistance. There is a paucity of research pertaining to consumers in the Australian healthcare environment. This study aimed to investigate the perspectives, attitudes and behaviours of Australian consumers on antibiotic use and antibiotic resistance, to inform national programs for reducing inappropriate antibiotic consumption. Semi-structured interviews with 32 consumers recruited via convenience and snowball sampling from a university population in South East Queensland. Interview transcripts were deductively and inductively coded. Main themes were identified using iterative thematic analysis. Three themes emerged from the analysis, to elucidate factors affecting antibiotic use: (a) prescription type; (b) consumer attitudes, behaviours, skills and knowledge; and (c) consumer engagement with antibiotic resistance. Consumers held mixed views regarding the use of delayed antibiotic prescriptions, and were often not made aware of the use of repeat antibiotic prescriptions. Consumers with regular general practitioners were more likely to have shared expectations regarding minimising the use of antibiotics. Even so, advice or information mediated by general practitioners was influential with all consumers; and helped to prevent inappropriate antibiotic use behaviours. Consumers were not aware of the free Return of Unwanted Medicines service offered by pharmacies and disposed of leftover antibiotics through household waste. To engage with mitigating antibiotic resistance, consumers required specific information. Previous public health campaigns raising awareness of antibiotics were largely not seen by this sample of consumers. Australian consumers have specific information needs regarding prescribed antibiotics to enable appropriate antibiotic use behaviours. Consumers also have expectations

    Full Text Available Abstract A recent study led by the Centers for Disease Control and Prevention (CDC revealed at least 30% of antibiotic prescriptions in the outpatient setting were inappropriate. In this study of all ages, among adult patients, results were similar to the overall population, with the majority of inappropriate prescribing relating to respiratory infections. We applied the same methodology to investigate rates of antibiotic prescribing for respiratory tract infections in outpatient primary care clinics at the Providence Veterans Affairs Medical Center. The results of our evaluation reflected comparable rates of inappropriate prescribing, but when stratified by teaching versus non-teaching primary care clinics, inappropriate prescribing was significantly higher in non-teaching clinics (17.6% vs 44.0%, p < .0001. Respiratory infection visits in non-teaching outpatient clinics may be a pragmatic target for antimicrobial stewardship programs.

    The present survey was conducted to investigate the price and availability of a basket of 24 essential antibiotics and eight high-end antibiotics at various levels of health care in public and private sector in National Capital Territory of Delhi, India using standardized WHO/HAI methodology. DATA ON PROCUREMENT PRICE AND AVAILABILITY WAS COLLECTED FROM THREE PUBLIC HEALTHCARE PROVIDERS IN THE STATE: the federal (central) government, state government and Municipal Corporation of Delhi (MCD). Overall a total of 83 public facilities, 68 primary care, 10 secondary cares and 5 tertiary care facilities were surveyed. Data was also collected from private retail (n = 40) and chain pharmacies (n = 40) of a leading corporate house. Prices were compared to an international reference price (expressed as median price ratio-MPR). PUBLIC SECTOR: Delhi state government has its essential medicine list (Delhi state EML) and was using Delhi state EML 2007 for procurement; the other two agencies had their own procurement list. All the antibiotics procured including second and third generation antibiotics except for injections were available at primary care facilities. Antibiotic available were on the basis of supply rather than rationality or the Delhi state EML and none was 100% available. There was sub-optimal availability of some essential antibiotics while other non-essential ones were freely available. Availability of antibiotics at tertiary care facilities was also sub-optimal. Private sector: Availability of antibiotics was good. For most of the antibiotics the most expensive and popular trade names were often available. High-end antibiotics, meropenam, gemifloxacin, and moxifloxacin were commonly available. In retail pharmacies some newer generation non-essential antibiotics like gemifloxacin were priced lower than the highest-priced generic of amoxicillin + clavulanic acid, azithromycin, and cefuroxime aexitl. Inappropriate availability and pricing of newer

    Full Text Available Pneumonia is one of infectious diseases that require a comprehensive and effective effort in its treatment, including in the use of empirical antibiotics. The use of empirical antibiotics should be based on patterns of sensitivity toward bacteria. The aim of this study was to evaluate the use of antibiotics based on the sensitivity patterns by clinical outcomes as the goal of treatment. This study was conducted in Hasan Sadikin Hospital Bandung in October–December 2013 using a retrospective cross-sectional study design. Secondary data were obtained from medical records during January 2011–December 2012. This study consisted of 24 patients with positive culture test and received antibiotic prescription. The results showed the percentage of the use of cefotaxime-ampicillin (37.5%, cefotaxime (33.3%, ceftriaxone (20.8%, and Ampicillin (8.4%. The most influential antibiotics for achieving clinical outcome using 95% confidence level is combination of cefotaxime-ampiciline (P=0.044 with 77.7% sensitivity level. This study suggested that the pattern of antibiotic sensitivity affected the clinical outcomes of pediatric patients with pneumonia.

    Full Text Available Introduction Antibiotics are essential and abundantly prescribed in hospitals because of their effectiveness and lifesaving benefits. However, the unnecessary use of antibiotics has been observed in earlier studies, and it has persisted through recent years as a major issue since it is one of the leading causes of antibiotic resistance. The increase in antibiotic resistance nowadays is one of the most critical concerns in global public health around the world. The objective of this study was to evaluate the knowledge and perceptions related to antibiotic prescription among physicians at our medical centers. Method A cross-sectional survey of non-infectious diseases specialized physicians. The study was conducted during 2015 at two tertiary care centers in Riyadh, Saudi Arabia. Result Of the 107 returned questionnaires, 93 were complete and valuable. Most respondents (82% perceived antibiotic resistance to be a critical problem globally, and 78% also think that it is a very important national problem. These attitudes did not differ across specialty or level of training. Widespread antibiotic use and inappropriate empirical choices were believed by 81% of the participants to be important general causes of resistance. Only half of respondents thought that antibiotic restriction is a useful intervention to decrease the antibiotic resistance. The physicians believed educational interventions are the most useful and effective way to improve prescription patterns and decrease antibiotic resistance. Complications due to infection with resistant organisms were acknowledged by almost all of the participants, with some differences in their estimations of how often it will occur. Conclusion Antimicrobial resistance, globally and nationally, is considered as a serious threat, and physicians in this survey acknowledged that. Among the most significant factors is antimicrobial misuse, either by overprescribing or providing inappropriate drugs with some

    Improper use of antibiotics increases antimicrobial resistance. Evaluate the use of antibiotics and the impact of an intervention designed to improve antibiotic prescription for surgical prophylaxis in 6 hospitals of Monterrey, Mexico. Design: A prospective multicenter survey and a pretest-postest experimental study. Phase 1: Survey to evaluate the use of antibiotics through an especially designed guide. Phase 2: Intervention designed to improve antibiotic prescription for surgical prophylaxis by the medical staff by using printed, audiovisual and electronic messages. Phase 3: Survey to evaluate the impact of the intervention. Frequencies, percentages, medians, ranges and X 2 test. Phase 1: We evaluated 358 surgical patients, 274 prophylactic antibiotic regimens. A total of 96% of antibiotics regimens began with inappropriate timing (290/302), 82.8% were inappropriate regimens (274/331), 77.7% were in inappropriate dosage (230/296), 86% of inadequate length (241/280), and in 17.4% restricted antibiotics were used (52/299). Phase 2: 9 sessions including 189 physicians (14 department chairs, 58 general practitioners and 117 residents). Phase 3: We evaluated 303 surgical patients, 218 prophylactic antibiotics regimens. Inappropriate treatment commencement was reduced to 84.1% (180/214) (P<0.001), inappropriate regimens to 75.3% (162/215) (P=0.03), inappropriate dosages to 51.2% (110/215) (P<0.001), and use of restricted antibiotics to 8.3% (18/215) (P=0.003). Inappropriate use of prophylactic antibiotics in surgery is a frequent problem in Monterrey. The intervention improved the antibiotic prescription for surgical prophylaxis by reducing inappropriate treatment commencement, regimens, dosages, and overuse of restricted antibiotics. It is necessary to strengthen strategies to improve the prescription of antibiotics in surgical prophylaxis. Copyright © 2016 Academia Mexicana de Cirugía A.C. Publicado por Masson Doyma México S.A.

    No previous analyses have attempted to determine optimal therapy for upper respiratory tract infections on the basis of cost-minimization models and the prevalence of antimicrobial resistance among respiratory pathogens in Slovakia. This investigation compares macrolides and cephalosporines for empirical therapy and look at this new tool from the aspect of potential antibiotic policy decision-making process. We employed a decision tree model to determine the threshold level of macrolides and cephalosporines resistance among community respiratory pathogens that would make cephalosporines or macrolides cost-minimising. To obtain information on clinical outcomes and cost of URTIs, a systematic review of the literature was performed. The cost-minimization model of upper respiratory tract infections (URTIs) treatment was derived from the review of literature and published models. We found that the mean cost of empirical treatment with macrolides for an URTIs was €93.27 when the percentage of resistant Streptococcus pneumoniae in the community was 0%; at 5%, the mean cost was €96.45; at 10%, €99.63; at 20%, €105.99, and at 30%, €112.36. Our model demonstrated that when the percentage of macrolide resistant Streptococcus pneumoniae exceeds 13.8%, use of empirical cephalosporines rather than macrolides minimizes the treatment cost of URTIs. Empirical macrolide therapy is less expensive than cephalosporines therapy for URTIs unless macrolide resistance exceeds 13.8% in the community. Results have important antibiotic policy implications, since presented model can be use as an additional decision-making tool for new guidelines and reimbursement processes by local authorities in the era of continual increase in antibiotic resistance.

    Full Text Available Superficial mycoses are estimated to affect more than 20-25% of the world’s population with a consistent increase over the years. Most patients referred to our clinic for suspected dermatomycoses have already been treated with pharmacotherapy, without a previous mycological examination and many show changes in the clinical manifestations. Indeed, some medications, such as steroids, antiviral, antibiotics and antihistamines are not able to erase a fungal infection, but also they can cause atypical clinical manifestations. The consequences of inappropriate treatment include delayed diagnosis, prolonged healing time, and additional costs. The aims of this study were (1 to evaluate the incidence of increased costs attributable to inappropriate therapy sustained by the National Health Service and patients and (2 to highlight the importance of mycological evaluation before starting treatment, in order to improve diagnostic accuracy. An observational retrospective and prospective study was performed from September 2013 to February 2014, in 765 patients referred to our center (University Hospital “ Federico II” in Naples, Italy, for suspected mycological infection. The following treatments (alone or in combination were defined as inappropriate: (1 cortisone in a patient with at least one positive site; (2 antifungals in (a patients with all negative sites or (b ineffective antifungal treatment (in terms of drug chosen, dose or duration in those with all positive sites; or (3 antibiotics; (4 antivirals or (5 antihistamines, in patients with ≥ 1 positive site. Five hundred and fifty patients were using medications before the assessment visit. The total amount of avoidable costs related to inappropriate previous treatments was € 121,417, representing 74% of the total treatment costs. 253/550 patients received drugs also after the visit. For these patients, the cost of treatment prescribed after mycological testing was € 42,952, with a decrease

    2013-06-01

    Full Text Available Inappropriate antibiotic use in normally self-limiting acute respiratory tract infections (RTIs, such as sore throat and the common cold, is a global problem and an important factor for increasing levels of antibiotic resistance. A new group of international experts—the Global Respiratory Infection Partnership (GRIP—is committed to addressing this issue, with the interface between primary care practitioners and their patients as their core focus. To combat the overuse of antibiotics in the community, and facilitate a change from prescribing empiric antibiotic treatment towards cautious deferment combined with symptomatic relief, there is a need to introduce and enhance evidence-based dialogue between primary care practitioners and their patients. Communication with patients should focus on the de-medicalisation of self-limiting viral infections, which can be achieved via a coherent globally endorsed framework outlining the rationale for appropriate antibiotic use in acute RTIs in the context of antibiotic stewardship and conservancy. The planned framework is intended to be adaptable at a country level to reflect local behaviours, cultures and healthcare systems, and has the potential to serve as a model for change in other therapeutic areas.

    Treatment for diabetic foot infections requires properly diagnosing infection, obtaining an appropriate specimen for culture, assessing for any needed surgical procedures and selecting an empiric antibiotic regimen. Therapy will often need to be modified based on results of culture and sensitivity testing. Because of excessive and inappropriate use of antibiotics for treating diabetic foot infections, resistance to the usually employed bacteria has been increasing to alarming levels. This article reviews recommendations from evidence-based guidelines, informed by results of systematic reviews, on treating diabetic foot infections. Data from the pre-antibiotic era reported rates of mortality of about 9% and of high-level leg amputations of about 70%. Outcomes have greatly improved with appropriate antibiotic therapy. While there are now many oral and parenteral antibiotic agents that have demonstrated efficacy in treating diabetic foot infections, the rate of infection with multidrug-resistant pathogens is growing. This problem requires a multi-focal approach, including providing education to both clinicians and patients, developing robust antimicrobial stewardship programmes and using new diagnostic and therapeutic technologies. Recently, new methods have been developed to find novel antibiotic agents and to resurrect old treatments, like bacteriophages, for treating these difficult infections. Medical and political leaders have recognized the serious global threat posed by the growing problem of antibiotic resistance. By a multipronged approach that includes exerting administrative pressure on clinicians to do the right thing, investing in new technologies and encouraging the profitable development of new antimicrobials, we may be able to stave off the coming 'post-antibiotic era'.

    A huge proportion of antibiotic therapies for infections caused by multidrug-resistant bacteria (MDR) are inappropriate. In this study, we described the most common causes of inappropriateness of definitive antibiotic regimes in a large university hospital in southern Italy and we evaluated the impact on microbial eradication, length of stay, 30-day readmission and mortality. We retrospectively assessed 45 patients who received a definitive antibiotic therapy after isolation of multidrug-resistant Staphylococcus aureus, Enterococcus spp., Enterobacteriaceae, Pseudomonas aeruginosa and Acinetobacter spp. strains between 2014 and 2015. From the literature, we set a series of criteria to retrospectively determine the appropriateness of the therapy. In all, 61% of the prescribed antibiotic regimes were found to be inappropriate, especially due to incorrect drug dosage. It emerged that meropenem was the antibiotic most frequently inappropriately used. In 46% of infections caused by MDR but not extended-spectrum β-lactamase-producing Enterobacteriaceae, carbapenems were inappropriately administered. Microbial eradication was achieved in 87% of the appropriate therapy group compared to 31% of the inappropriate therapy group (chi-square=6.750, p<0.027). No statistically significant association was found between inappropriate therapy and the length of stay (chi-square=3.084, p=0.101) and 30-day readmission (p=0.103). Definitive antibiotic therapy in infections caused by multidrug-resistant bacteria in a large university hospital is often inappropriate, especially due to the drug dosing regimen, particularly in the case of meropenem and colistin. This inappropriateness has a significant impact on post-treatment microbial eradication in specimens collected after antibiotic therapy.

    Millions of patients are evaluated every year in the emergency department (ED) for bacterial infections. Emergency physicians often diagnose and prescribe initial antibiotic therapy for a variety of bacterial infections, ranging from simple urinary tract infections to severe sepsis. In life-threatening infections, inappropriate choice of initial antibiotic has been shown to increase morbidity and mortality. As such, initiation of appropriate antibiotic therapy on the part of the emergency physician is critical. Increasing rates of antibiotic resistance, drug allergies, and antibiotic shortages further complicates the choice of antibiotics. Patients may have a history of prior resistant infections or culture data indicating that common first-line antibiotics used in the ED may be ineffective. In recent years, there have been several new antibiotic approvals as well as renewed interest in second and third line antibiotics because of the aforementioned concerns. In addition, several newly approved antibiotics have the advantage of being administered once weekly or even as a single infusion, which has the potential to decrease hospitalizations and healthcare costs. This article reviews newly approved antibiotics and antibiotics used to treat resistant infections with a focus on implications for emergency medicine. Copyright © 2016 Elsevier Inc.

    Behavioral economics interventions have been shown to effectively reduce the rates of inappropriate antibiotic prescriptions for acute respiratory infections (ARIs). To determine the cost-effectiveness of three behavioral economic interventions designed to reduce inappropriate antibiotic prescriptions for ARIs. Thirty-year Markov model from the US societal perspective with inputs derived from the literature and CDC surveillance data. Forty-five-year-old adults with signs and symptoms of ARI presenting to a healthcare provider. (1) Provider education on guidelines for the appropriate treatment of ARIs; (2) Suggested Alternatives, which utilizes computerized clinical decision support to suggest non-antibiotic treatment choices in lieu of antibiotics; (3) Accountable Justification, which mandates free-text justification into the patient's electronic health record when antibiotics are prescribed; and (4) Peer Comparison, which sends a periodic email to prescribers about his/her rate of inappropriate antibiotic prescribing relative to clinician colleagues. Discounted costs, quality-adjusted life years (QALYs), and incremental cost-effectiveness ratios. Each intervention has lower costs but higher QALYs compared to provider education. Total costs for each intervention were $178.21, $173.22, $172.82, and $172.52, and total QALYs were 14.68, 14.73, 14.74, and 14.74 for the control, Suggested Alternatives, Accountable Justification, and Peer Comparison groups, respectively. Results were most sensitive to the quality-of-life of the uninfected state, and the likelihood and costs for antibiotic-associated adverse events. Behavioral economics interventions can be cost-effective strategies for reducing inappropriate antibiotic prescriptions by reducing healthcare resource utilization.

    Ventilator-associated pneumonia (VAP) occurs in up to 25% of mechanically ventilated patients, with an associated mortality up to 50%. Early diagnosis and appropriate empiric antibiotic coverage of VAP are crucial. Given the multitude of noninfectious clinical and radiographic anomalies within trauma patients, microbiology from bronchioalveolar lavage (BAL) is often needed. Empiric antibiotics are administered while awaiting BAL culture data. Little is known about the effects of these empiric antibiotics on patients with negative BAL microbiology if a subsequent VAP occurs during the same hospital course. This is a retrospective chart review of intubated trauma patients undergoing BAL for suspected pneumonia over a 3-y period at a Level 1 trauma center. All patients with suspected VAP undergoing a BAL receive empiric antibiotics. If microbiology data are negative at 72 h, all antibiotics are stopped; however, if the BAL returns with ≥10(5) colony-forming units per milliliter, the diagnosis of VAP is confirmed. We divided patients into three groups. Group 1 consisted of patients in whom the initial BAL was positive for VAP. Group 2 consisted of patients with an initial negative BAL, who subsequently developed VAP at a later point in the hospital course. Group 3 consisted of patients with negative BAL who did not develop a subsequent VAP. We obtained 499 BAL specimens in 185 patients over the 3-y period. A total of 14 patients with 23 BAL specimens initially negative for VAP subsequently developed VAP later during the same hospital stay. These patients did not have an increase in the hospital length of stay, intensive care unit days, ventilator days, or mortality compared with those who had a positive culture on the first suspicion of VAP. There was a significant increase in the percentage of Enterobacter (21% versus 8%) and Morganella (8% versus 0%) as the causative organism in these 14 patients when the VAP occurred. Furthermore, the profile of the top two

    The increasing antibiotic resistance is a global threat to health care as we know it. Yet there is no model of distribution ready for a new antibiotic that balances access against excessive or inappropriate use in rural settings in low- and middle-income countries (LMICs) where the burden of communicable diseases is high and access to quality health care is low. Departing from a hypothetical scenario of rising antibiotic resistance among pneumococci, 11 stakeholders in the health systems of various LMICs were interviewed one-on-one to give their view on how a new effective antibiotic should be distributed to balance access against the risk of inappropriate use. Transcripts were subjected to qualitative 'framework' analysis. The analysis resulted in four main themes: Barriers to rational access to antibiotics; balancing access and excess; learning from other communicable diseases; and a system-wide intervention. The tension between access to antibiotics and rational use stems from shortcomings found in the health systems of LMICs. Constructing a sustainable yet accessible model of antibiotic distribution for LMICs is a task of health system-wide proportions, which is why we strongly suggest using systems thinking in future research on this issue.

    The clinical practice guidelines on nosocomial pneumonia recommends an empirical regimen that would work in 95% of the patients based on the local antibiogram. The aim of the study was development of an antibiogram for guiding empiric therapy in settings with high prevalence of multi-drug resistant organisms. A retrospective review of electronic health records (e-hospital portal) was done to analyze all respiratory isolates from patients admitted in medical wards and intensive care unit between May 2016 and May 2017. The samples included brocho-alveolar lavage (BAL), mini broncho-alveolar lavage (mini-BAL) and endotracheal aspirate. The sensitivity pattern (combined and individual) of all bacterial isolates were analysed for commonly used antibiotics and their combinations. Out of the 269 isolates, the most common organisms were Pseudomonas aeruginosa (125, 46%), Acinetobacter baumanni (74, 27%) and Klebsiella pneumoniae (50, 19%). Cefoperazone-sulbactam (43%) had the best sensitivity pattern overall. Cefoperazone-sulbactam plus amikacin (56%) was the combination with the best combined sensitivity overall. There is a high prevalence of resistance in the commonly implicated organisms to the available antibiotics. There is an urgent need for implementation of effective anti-microbial stewardship programmes and development of newer antimicrobials.

    Monotherapy is recommended as the first choice for initial empirical therapy of febrile neutropenia, but local epidemiological and antibiotic susceptibility data are now considered pivotal to design a correct management strategy. To evaluate the proportion of Gram-negative rods isolated in bloodstream infections in children with cancer resistant to antibiotics recommended for this indication. The in vitro susceptibility to ceftazidime, piperacillin-tazobactam, meropenem and amikacin of Gram-negatives isolated in bacteremic episodes in children with cancer followed at the Istituto "Giannina Gaslini", Genoa, Italy in the period of 2001-2013 was retrospectively analyzed using the definitions recommended by EUCAST in 2014. Data were analyzed for any single drug and to the combination of amikacin with each β-lactam. The combination was considered effective in absence of concomitant resistance to both drugs, and not evaluated by means of in vitro analysis of antibiotic combinations (e.g., checkerboard). A total of 263 strains were evaluated: 27% were resistant to piperacillin-tazobactam, 23% to ceftazidime, 12% to meropenem and 13% to amikacin. Concomitant resistance to β-lactam and amikacin was detected in 6% of strains for piperacillin-tazobactam, 5% for ceftazidime and 5% for meropenem. During the study period there was a nonsignificant increase in the proportions of strains resistant to β-lactams indicated for monotherapy, and also increase in the resistance to combined therapies. in an era of increasing resistance to antibiotics guideline-recommended monotherapy could be not appropriate for initial empirical therapy of febrile neutropenia. Strict local survey on etiology and antibiotic susceptibility is mandatory for a correct management of this complication in cancer patients.

    Abstract Background A national assessment of antibiotic appropriateness in intensive care units (ICUs) with benchmarking was performed to assist antibiotic stewardship programs (ASPs) identify improvement opportunities. Methods A Centers for Disease Control and Prevention tool was adapted by an expert panel from the Partnership for Quality Care (PQC), a coalition dedicated to high quality care in US hospitals, to validate appropriate antibiotic use measurement via a point prevalence survey on a single day. Data were collected by ASP personnel at each hospital, de-identified and submitted in aggregate to PQC for benchmarking. Hospitals identified reasons for inappropriate antibiotic use by category and antibiotics misused. Results Forty-seven ICUs from 12 PQC hospitals participated: California (2), Florida (2), Massachusetts (3), Minnesota (1), and New York (4). Most hospitals identified as teaching (83%) with 252-1550 bed size (median: 563) and 20–270 licensed ICU beds (median: 70). All hospitals reported a formal ASP. On March 1, 2017, 362 (54%) of 667 patients in participating ICUs were on antibiotics (range: 8-81 patients); 1 patient was not assessed. Of the remaining 361 antibiotic regimens, 112 (31%) were identified as inappropriate from among all 12 hospitals (range: 9-82%) (figure). The table displays inappropriate antibiotic use by ICU type. Reasons for inappropriate use included unnecessarily broad spectrum of activity (29%), duration longer than necessary (21%), and treatment of a non-infectious syndrome (19%). The antibiotic most commonly misused was vancomycin in 7 (58%) hospitals. Conclusion Up to 80% of antibiotic use in some ICUs is inappropriate, underscoring the need for ASP interventions, standardized assessment tools and benchmarking. Strategies should focus on de-escalation of broad-spectrum antibiotics and reducing duration of therapy. Disclosures D. W. Kubiak, Shionogi: Consultant, Consulting fee.

    Full Text Available Urinary tract infections (UTI are one of the most common infections with an increasing resistance to antimicrobial agents. PURPOSE: Empirical initial antibiotic treatment of UTI must rely on susceptible data from local studies. MATERIALS AND METHODS: Retrospective analysis of isolated bacteria from children with UTIs was performed at the university hospital during years 2006-2009. The findings were compared with data collected in a similar study carried out in 2002- 2003. RESULTS: A total of 1439 uropathogens were isolated. Escherichia coli (E.coli was the leading cause, followed by Enterobacter, and other gram negative bacilli. It was observed resistance of E.coli to ceftriaxone, cefexime, amikacin, gentamycin, and nalidixic acid; Enterobacter to cefexime; and the resistance of gram negative bacilli to gentamicin and cefexime increased significantly. The highest effective antibiotic was Imipenem, ciprofloxacin, and amikacin with 96.7%, 95% and 91% sensitivity rates , respectively, followed by ceftriaxone 77.2%, gentamicin 77%, nitrofurantoin 76.4%, nalidixic acid 74.3% and cefexime with 70%. CONCLUSION: The use of nitrofurantoin or nalidixic acid as initial empirical antibacterial therapy for cystitis seems appropriate. For cases of simple febrile UTI, the use of initial parenteral therapies with amikacin or ceftriaxone followed by an oral third generation cephalosporin also seemed appropriated, and in cases of severely ill patients or complicated UTI, imipenem as monotherapy or, a combination of Ceftriaxone with an aminoglycoside, are recommended.

    Full Text Available Background Use of antibiotics to treat self-limiting viral infections like dengue fever (DF without any co-morbid conditions in pediatric patients is common practice in India, and a major contribution of the inappropriate use of antibiotics in the country. Objective To provide an analysis of diagnosis, grading, and prescribing of antibiotics in pediatric inpatients with DF in a tertiary care teaching hospital in India. Methods Data from case sheets of all pediatric inpatients (n=370 diagnosed with DF without co-morbid conditions were collected with regards to diagnosis, grading, presence, and appropriateness of antibiotic usage according to the 2009 WHO Guidelines, the National Vector Borne Disease Control Program (NVBDCP of India Guidelines, and the Hospital Infection Society (HIS Guidelines. Results Platelet count determination (50% of the cases was the major diagnostic method for dengue. Inappropriate grading of DF was seen in 20% of patients. Almost 75% of the 370 dengue cases were prescribed antibiotics for the expressed purpose of avoiding hospital-acquired infections. A single antibiotic was given in 225 cases (60.81%, 2 antibiotics in 33 (8.91 % cases, and 3 antibiotics in 9 (2.43% cases. Conclusions From the results it is clear that antibiotics were prescribed to treat DF where the antibiotics do not have any role. DF is a self-limiting viral infection that can be treated with proper management of hemodynamic status with IV fluids. To avoid the usage of antibiotics in the treatment of dengue, awareness has to be created in healthcare professionals regarding the treatment guidelines for dengue and appropriate use of antibiotics to avoid hospital acquired infections.

    Full Text Available Functional gastrointestinal symptoms such us bloating, fullness, flatulence, diarrhea, and constipation due to irritable bowel syndrome (IBS were recently attributed to small bowel bacterial overgrowth, a condition depending on the presence of an increased number of bacteria in the small bowel. However, the methodology used to describe this association may be harshly criticized, since it has already been shown to be quite inaccurate. As a result an inappropriate use of antibiotics was consequently generated. In fact, antibiotics could be effective in the treatment of functional complaints, but only in a limited subgroup of patients, characterized by an increase of fermentation at colonic level. In this review, we have examined the papers suggesting a pathophysiological link between IBS and small bowel bacterial overgrowth, underlining its inappropriateness, and put forth our personal view on the rationale for antibiotic use in IBS.

    Full Text Available Surgical site infections are one of the most important post-surgery complications. Antimicrobial prophylaxis has been used routinely in surgeries to reduce infection incidence. However, inappropriate selection of antimicrobial agents or dosing can develop antimicrobial resistance, serious adverse reactions and prolong hospitalization. Current study aimed to examine prophylactic antibiotic prescription in surgeries in a teaching hospital in Sari, Mazandaran and evaluate level of adherence to the international guidelines. Between January 2015 to May 2015, 104 patients in general surgery ward were selected and enrolled in the study. The prophylactic antibiotics, dosage, timing and duration of administration were collected by reviewing patients’ records and compared to the existing guidelines. Prophylactic antibiotic was given to 85.5% of patients. Prescribed antibiotics were cefazolin (46.1%, metronidazole (24%, ceftriaxone (12.5%, ciprofloxacin (1.9% and vancomycin (0.96%. Most of the patients (62.9% received an inappropriate and delayed timing. Proper antibiotic dosage was seen in 45.2% of patients. All patients received post-operative prophylactic antibiotic. Main antibiotics include cefazolin (41.3%, metronidazole (33.7%, ceftriaxone (31.7% and clindamycin (20.2%. Only 10 (21.9% patients received cefazolin or vancomycin for a total duration of 48 hours or less. Surgical wound infection occurred in 17 (16.3% patients during hospital stay. Adherence to antimicrobial prophylaxis guidelines was completely achieved in 14.4% of cases. Results of this study signified that adherence to existing guidelines was poor and the most common mistakes were over usage, inappropriate dosage and choosing of antibiotics.

    Full Text Available Vancomycin is an antibiotic used for infections by gram-positive bacteria with a two-compartment pharmacokinetic model. Its monitoring has an established therapeutic range (10-20 mg/L to prevent nephrotoxicity and ototoxicity due to supratherapeutic levels, and inefficiency and development of resistance by subtherapeutic levels. Nephrotoxicity for vancomycin monotherapy at standard doses according to pathogen and typical regimens (usual dose: 15-20 mg/kg/12 h is rare and usually reversible. Moreover, monitoring plasma concentrations allows to achieve concentrations within therapeutic range to allow safe and effective drug use. The renal hypoperfusion can cause pre-renal damage, resulting in elevated levels of serum creatinine, resulting in decreased antibiotic elimination and nephrotoxicity. We report a case of unexpected vancomycin nephrotoxicity in a patient with syndrome Inappropriate antidiuretic hormone secretion associated paraneoplastic

    To find the in-vitro sensitivity data and clinical response in order to determine the changes required in empiric antibiotic therapy for management of febrile neutropenia in paediatric patients undergoing peripheral blood stem cell transplantation. All patients were treated according to institutional protocol for febrile neutropenia. Empirical antibiotics include Ceftriaxone and Amikacin. In non-responders, changes made included Imipenem and Amikacin, Piperacillin Tazobactum/Tiecoplanin or Vancomycin/Cloxacilin/Ceftazidime. In non-responders, amphotaracin was added until recovery. Out of 52 patients, 5 did not develop any fever; in the remaining 47 patients there were 57 episodes of febrile neutropenia. The mean days of febrile episodes were 4.71 (range 3-8). Fever of unknown origin (FUO) occurred in 31 (54.3%) episodes. Microbiologically documented infection (MDI) occurred in 17 (29.8%) episodes of fever. Clinically documented infection (CDI) occurred in 9 (15.7%) episodes. Gram-negative organisms were isolated in 10 while gram-positive organisms in 7. Klebseilla, S. aureus were the most common isolates. Empirical therapy was effective in 12 of the 33 (36%) episodes. Out of 28, 26 (92%) responded to Imipenem/Amikacin as second line therapy while those who received any other second line combination, only 11 out of 22 (50%) showed response. Systemic Amphotericin was used in 4 patients, 2 responded. Infection related mortality rate was 4%. (author)

    2007-06-01

    Full Text Available Abstract Background There are many examples of physicians using treatments inappropriately, despite clear evidence about the circumstances under which the benefits of such treatments outweigh their harms. When such over- or under- use of treatments occurs for common diseases, the burden to the healthcare system and risks to patients can be substantial. We propose that a major contributor to inappropriate treatment may be how clinicians judge the likelihood of important treatment outcomes, and how these judgments influence their treatment decisions. The current study will examine the role of judged outcome probabilities and other cognitive factors in the context of two clinical treatment decisions: 1 prescription of antibiotics for sore throat, where we hypothesize overestimation of benefit and underestimation of harm leads to over-prescription of antibiotics; and 2 initiation of anticoagulation for patients with atrial fibrillation (AF, where we hypothesize that underestimation of benefit and overestimation of harm leads to under-prescription of warfarin. Methods For each of the two conditions, we will administer surveys of two types (Type 1 and Type 2 to different samples of Canadian physicians. The primary goal of the Type 1 survey is to assess physicians' perceived outcome probabilities (both good and bad outcomes for the target treatment. Type 1 surveys will assess judged outcome probabilities in the context of a representative patient, and include questions about how physicians currently treat such cases, the recollection of rare or vivid outcomes, as well as practice and demographic details. The primary goal of the Type 2 surveys is to measure the specific factors that drive individual clinical judgments and treatment decisions, using a 'clinical judgment analysis' or 'lens modeling' approach. This survey will manipulate eight clinical variables across a series of sixteen realistic case vignettes. Based on the survey responses, we will be

    Much progress has been made in understanding the main causes of blood culture-negative endocarditis (BCNE). Few studies concerning BCNE treatment (due to previous antibiotics used or fastidious pathogens) are available. We performed this study to evaluate the effectiveness of our therapeutic protocol in BCNE, based on compliance with the protocol, outcome and 1 year mortality. We collected prospectively and analysed retrospectively cases of BCNE between 2002 and 2014, using a simplified and standardized protocol developed by our multidisciplinary team. We apply two kinds of protocols to treat BCNE, which include only four intravenous antimicrobial agents: amoxicillin, vancomycin, gentamicin and amphotericin B. We had 177 patients with definite BCNE. There were 154 (87.0%) patients treated with both appropriate antimicrobial agents and appropriate duration of treatment. We analysed the causes of inappropriate treatment in 13 (7.3%) cases and inappropriate duration in 10 (5.6%) cases. The treatment changes were justified in all cases except one of discharge against medical advice. The fatality rate was 5.1% (nine cases) and all deaths occurred in the group of patients who were treated with appropriate treatment; however, four deaths were not attributable to empirical treatment failure. Concerning the other deaths, the lack of surgical management, in association with empirical treatment, could explain our protocol's failure, such as poorly tolerated surgery. Our protocol is efficient and our mortality rate was low, compared with the literature review. This may result from a strategy that uses a sampling procedure and a standardized protocol at the same time. © The Author 2016.

    Full Text Available Background: Antibiotics are considered among the most commonly prescribed drug classes in developing countries. Inappropriate prescription of antibiotics is a major public health concern and is related to the development of antimicrobial resistance. Objective: This study aimed at assessing the appropriateness of antibiotic prescription by non-infectious disease physicians in a community setting in Lebanon. Methods: A pilot cross-sectional study was undertaken on community pharmacy patients presenting with antibiotic prescription. It was performed over a period of 4 months in different regions of Lebanon. Participants answered a questionnaire inquiring about socio-demographic characteristics, medical conditions, symptoms that required medical attention, the doctor's diagnosis, the prescribed antibiotic, and whether laboratory tests were ordered to identify the causative organism or not. Data were analyzed using SPSS 17. Results: We studied 270 patients (49.3% males and 50.7% females. This study showed that the most-prescribed antibiotics were the cephalosporins (82% and that almost half of the illnesses for which antibiotics were prescribed were respiratory tract infections (41%. The study also showed that the choice of the prescribed antibiotic was appropriate in 61.5% of the studied cases, while the prescribed dose and the duration of the treatment were inaccurate in 52 and 64% of the cases, respectively. In addition, fever seemed to be a factor that influenced the physician's prescriptions, since the choice of drug conformity to guidelines increased from 53.7% (1 day of fever to 88.9% (1 week of fever, and the dose prescription compliance to guidelines was higher (55.9% for patients suffering from fever compared to those with no fever (38.1%. Conclusion: This study showed a high prevalence of inappropriate antibiotic prescriptions in Lebanon. Therefore, actions should be taken to optimize antibiotic prescription.

    Antibiotics are one the most common therapies administered in the intensive care unit setting. This review outlines the strategy for optimal use of antimicrobial agents in the critically ill. In severely ill patients, empirical antimicrobial therapy should be used when a suspected infection may impair the outcome. It is necessary to collect microbiological documentation before initiating empirical antimicrobial therapy. In addition to antimicrobial therapy, it is recommended to control a focus of infection and to modify factors that promote microbial growth or impair the host's antimicrobial defence. A judicious choice of antimicrobial therapy should be based on the host characteristics, the site of injection, the local ecology, and the pharmacokinetics/pharmacodynamics of antibiotics. This means treating empirically with broad-spectrum antimicrobials as soon as possible and narrowing the spectrum once the organism is identified (de-escalation), and limiting duration of therapy to the minimum effective period. Despite theoretical advantages, a combined antibiotic therapy is nor more effective than a mono-therapy in curing infections in most clinical trials involving intensive care patients. Nevertheless, textbooks and guidelines recommend a combination for specific pathogens and for infections commonly caused by these pathogens. Avoiding unnecessary antibiotic use and optimizing the administration of antimicrobial agents will improve patient outcomes while minimizing risks for the development of bacterial resistance. It is important to note that each intensive care unit should have a program in place which monitors antibiotic utilisation and its effectiveness. Only in this way can the impact of interventions aimed at improving antibiotic use be evaluated at the local level.

    Inappropriate antibiotics prescription in dental healthcare delivery that may result in the emergence of antibiotic-resistant bacteria, is a worldwide concern. The objective of the study was to determine the antibiotics knowledge and prescription patterns among dentists in Nigeria. A total of 160 questionnaires were distributed to dentists attending continuing education courses organized by two organizations in Southern and Northern parts of Nigeria. Data analysis was done using SPSS version 17.0. A total of 146 questionnaires were returned, properly filled, out of 160 questionnaires, giving an overall response rate 91.3%. The clinical factors predominantly influenced the choice of therapeutic antibiotics among the respondents. In this study, the most commonly prescribed antibiotics among the respondents was a combination of amoxicillin and metronidazole. Of the respondents, 136 (93.2%) of them considered antibiotic resistance as a major problem in Nigeria and 102 (69.9%) have experienced antibiotics resistance in dental practice. The major reported conditions for prophylactic antibiotics among the respondents were diabetic mellitus, HIV/AIDS, history of rheumatic fever, other heart anomalies presenting with heart murmur and presence of prosthetic hip. The knowledge of adverse effects of antibiotics was greatest for tooth discoloration which is related to tetracycline. Data from this study revealed the most commonly prescribed antibiotics as a combination of amoxicillin and metronidazole. There existed gaps in prophylactic antibiotic prescription, consideration in the choice of therapeutic antibiotics and knowledge of adverse effects of antibiotics among the studied dentists.

    Full Text Available Antibiotics serve very useful therapeutic purpose in eradicating pathogens. Unfortunately excessive and inappropriate use of antibiotics results in antibiotic resistance. The consequences of inappropriate self-medication with antibiotics among healthcare professionals have severe implications which might be legal issues, ethical issues, negative impacts on patient and poor quality of health care delivery. The present study was conducted on self-medication by undergraduate nursing students in a government medical college of West Bengal, India. A pre designed questionnaire was used to collect the relevant information pertaining to the study variables. Among the participants 54.2% had self-medicated in the last six months. The antibiotics most commonly used being metronidazole (67.4%, azithromycin (32.6% and norfloxacin (16.8%. Regarding the source of the antibiotics used for self-medication 41.6% participants went for leftover medicines at home, 34.8% participants obtained the drug from community pharmacies or drug stores. Hospital pharmacies and medicine samples were the source of the drugs for 19.2% and 4.4% participants respectively for this purpose. This study has shown that self-medication with antibiotics is common among undergraduate nursing students. There is a need for a rigorous mass enlightenment campaign to educate the population, including the health care professional about the disadvantages and possible complications of antibiotic self-medication.

    Full Text Available The rise of resistance together with the shortage of new broad-spectrum antibiotics underlines the urgency of optimizing the use of available drugs to minimize disease burden. Theoretical studies suggest that coordinating empirical usage of antibiotics in a hospital ward can contain the spread of resistance. However, theoretical and clinical studies came to different conclusions regarding the usefulness of rotating first-line therapy (cycling. Here, we performed a quantitative pathogen-specific meta-analysis of clinical studies comparing cycling to standard practice. We searched PubMed and Google Scholar and identified 46 clinical studies addressing the effect of cycling on nosocomial infections, of which 11 met our selection criteria. We employed a method for multivariate meta-analysis using incidence rates as endpoints and find that cycling reduced the incidence rate/1000 patient days of both total infections by 4.95 [9.43-0.48] and resistant infections by 7.2 [14.00-0.44]. This positive effect was observed in most pathogens despite a large variance between individual species. Our findings remain robust in uni- and multivariate metaregressions. We used theoretical models that reflect various infections and hospital settings to compare cycling to random assignment to different drugs (mixing. We make the realistic assumption that therapy is changed when first line treatment is ineffective, which we call "adjustable cycling/mixing". In concordance with earlier theoretical studies, we find that in strict regimens, cycling is detrimental. However, in adjustable regimens single resistance is suppressed and cycling is successful in most settings. Both a meta-regression and our theoretical model indicate that "adjustable cycling" is especially useful to suppress emergence of multiple resistance. While our model predicts that cycling periods of one month perform well, we expect that too long cycling periods are detrimental. Our results suggest that

    We analyzed China's current use of and microbial resistance to antibiotics, and possible means of reducing antimicrobial resistance. Interventions like executive orders within clinical settings and educational approach with vertical approaches rather than an integrated strategy to curb the use of antimicrobials remain limited. An underlying problem is the system of incentives that has resulted in the intensification of inappropriate use by health professionals and patients. There is an urgent need to explore the relationship between financial and non-financial incentives for providers and patients, to eliminate inappropriate incentives. China's national health reforms have created an opportunity to contain inappropriate use of antibiotics through more comprehensive and integrated strategies. Containment of microbial resistance may be achieved by strengthening surveillance at national, regional and hospital levels; eliminating detrimental incentives within the health system; and changing prescribing behaviors to a wider health systems approach, to achieve long-term, equitable and sustainable results and coordinate stakeholders' actions through transparent sharing of information.

    BACKGROUND AND OBJECTIVE: Drug therapy is necessary to treat acute illness, maintain current health and prevent further decline. However, optimizing drug therapy for older patients is challenging and sometimes, drug therapy can do more harm than good. Drug utilization review tools can highlight instances of potentially inappropriate prescribing to those involved in elderly pharmacotherapy, i.e. doctors, nurses and pharmacists. We aim to provide a review of the literature on potentially inappropriate prescribing in the elderly and also to review the explicit criteria that have been designed to detect potentially inappropriate prescribing in the elderly. METHODS: We performed an electronic search of the PUBMED database for articles published between 1991 and 2006 and a manual search through major journals for articles referenced in those located through PUBMED. Search terms were elderly, inappropriate prescribing, prescriptions, prevalence, Beers criteria, health outcomes and Europe. RESULTS AND DISCUSSION: Prescription of potentially inappropriate medications to older people is highly prevalent in the United States and Europe, ranging from 12% in community-dwelling elderly to 40% in nursing home residents. Inappropriate prescribing is associated with adverse drug events. Limited data exists on health outcomes from use of inappropriate medications. There are no prospective randomized controlled studies that test the tangible clinical benefit to patients of using drug utilization review tools. Existing drug utilization review tools have been designed on the basis of North American and Canadian drug formularies and may not be appropriate for use in European countries because of the differences in national drug formularies and prescribing attitudes. CONCLUSION: Given the high prevalence of inappropriate prescribing despite the widespread use of drug-utilization review tools, prospective randomized controlled trials are necessary to identify useful interventions.

    Abstract Background The Infectious Diseases Society of America (IDSA) recommends hospitals implement antimicrobial stewardship programs (ASP) in order to decrease inappropriate antibiotic use due to the rise in antibiotic-resistant infections. Data are limited on the extent to which different ASP strategies influence appropriate antibiotic use. Methods We conducted an online survey in 2016 of U.S. Children’s Hospitals to collect hospital-level information on dedicated ASP effort, ASP monitoring activities, use of audit-feedback, formulary restrictions, rapid diagnostics, etc. During the same period the ASP teams at these hospitals completed 3 point prevalence surveys that documented details on all admitted patients 0–17 years receiving any antibiotics, determined what ASP modifications could be made, and if the antibiotic was appropriate. We employed hierarchical, multivariable logit models to examine which ASP-related, hospital-level strategies were associated with appropriate antibiotic use. Results Thirty hospitals participated. A total of 6,921 patients were included, representing 10,068 total antibiotics. Of these orders, 8,554 (85.0%) were categorized as appropriate, though this varied across sites (range: 68-92%). Additionally, 78.2% of antibiotics did not have recommended modifications. Appropriate antibiotic use was significantly higher for hospitals that relied on rapid diagnostics (aOR: 1.6; P Terrill, Merck: Grant Investigator, Research grant Allergan: Grant Investigator, Research grant.

    Background Prolonged empiric antibiotics therapy in neonates results in several adverse consequences including widespread antibiotic resistance, late onset sepsis (LOS), necrotizing enterocolitis (NEC), prolonged hospital course (HC) and increase in mortality rates. Objectives To assess the risk factors and the outcome of prolonged empiric antibiotic therapy in very low birth weight (VLBW) newborns. Materials and Methods Prospective study in VLBW neonates admitted to NICU and survived > 2 W, from July 2011 - June 2012. All relevant perinatal and postnatal data including duration of antibiotics therapy (Group I 2W) and outcome up to the time of discharge or death were documented and compared. Results Out of 145 newborns included in the study, 62 were in group I, and 83 in Group II. Average duration of antibiotic therapy was 14 days (range 3 - 62 days); duration in Group I and Group II was 10 ± 2.3 vs 25.5 ± 10.5 days. Hospital stay was 22.3 ± 11.5 vs 44.3 ± 14.7 days, respectively. Multiple regression analysis revealed following risk factors as significant for prolonged empiric antibiotic therapy: VLBW especially stage II, 12 (8.3%) newborns died. Infant mortality alone and with LOS/NEC was higher in group II as compared to group I (P < 0.002 and < 0.001 respectively). Conclusions Prolonged empiric antibiotic therapy caused increasing rates of LOS, NEC, HC and infant mortality. PMID:27307961

    As the growth of antibiotic resistance has resulted in large part from widespread use of antibiotics, every effort must be made to ensure their sustainable use. This narrative review aims to assess the potential contribution of health economic analyses to sustainable use efforts. The work draws on existing literature and experience with health economic tools. The study examines some of the weaknesses in the health, regulatory, and industry arenas that could contribute to inappropriate or suboptimal prescribing of antibiotics and describes how economic analysis could be used to improve current practice by comparing both costs and health outcomes to maximize societal wellbeing over the longer-term. It finds that economic considerations underpinning current antibiotic prescribing strategies are incomplete and short-termist, with the result that they may foster suboptimal use. It also stresses that perverse incentives that drive antibiotic sales and inappropriate prescribing practices must be dis-entangled for sustainable use policies to gain traction. Finally, payment structures can be used to re-align incentives and promote optimal prescribing and sustainable use more generally. In particular, eliminating or altering reimbursement differentials could help steer clinical practice more deliberately towards the minimization of selection pressure and the resulting levels of antibiotic resistance. This work highlights the need for appropriately designed cost-effectiveness analyses, incentives analysis, and novel remuneration systems to underpin sustainable use policies both within and beyond the health sector.

    Insight into factors that influence antibiotic prescribing is crucial when developing interventions aimed at a more rational use of antibiotics. We examined factors that influence antibiotic prescribing in long-term care facilities, and present a conceptual model that integrates these factors. Semi-structured qualitative interviews were conducted with physicians (n = 13) and nursing staff (n = 13) in five nursing homes and two residential care homes in the central-west region of the Netherlands. An iterative analysis was applied to interviews with physicians to identify and categorize factors that influence antibiotic prescribing, and to integrate these into a conceptual model. This conceptual model was triangulated with the perspectives of nursing staff. The analysis resulted in the identification of six categories of factors that can influence the antibiotic prescribing decision: the clinical situation, advance care plans, utilization of diagnostic resources, physicians' perceived risks, influence of others, and influence of the environment. Each category comprises several factors that may influence the decision to prescribe or not prescribe antibiotics directly (e.g. pressure of patients' family leading to antibiotic prescribing) or indirectly via influence on other factors (e.g. unfamiliarity with patients resulting in a higher physician perceived risk of non-treatment, in turn resulting in a higher tendency to prescribe antibiotics). Our interview study shows that several non-rational factors may affect antibiotic prescribing decision making in long-term care facilities, suggesting opportunities to reduce inappropriate antibiotic use. We developed a conceptual model that integrates the identified categories of influencing factors and shows the relationships between those categories. This model may be used as a practical tool in long-term care facilities to identify local factors potentially leading to inappropriate prescribing, and to subsequently

    Antibiotic overuse is driving the emergence of antibiotic resistance worldwide. Good data on prescribing behaviours of healthcare providers are needed to support antimicrobial stewardship initiatives. This study examined the differences in antibiotic prescribing rates of public and private primary care clinics in Malaysia. We used data from the National Medical Care Survey (NMCS), a nationwide cluster sample of Malaysian public and private primary care clinics in 2014. NMCS contained demographic, diagnoses and prescribing from 129 public clinics and 416 private clinics. We identified all encounters who were prescribed antibiotic and analyse the prescribing rate, types of antibiotics, and diagnoses that resulted in antibiotic. Five thousand eight hundred ten encounters were prescribed antibiotics; antibiotic prescribing rate was 21.1 % (public clinics 6.8 %, private clinics 30.8 %). Antibiotic prescribing was higher in private clinics where they contributed almost 87 % of antibiotics prescribed in primary care. Upper respiratory tract infection (URTI) was the most frequent diagnosis in patients receiving antibiotic therapy and accounted for 49.2 % of prescriptions. Of the patients diagnosed with URTI, 46.2 % received antibiotic treatment (public 16.8 %, private 57.7 %). Penicillins, cephalosporins and macrolides were the most commonly prescribed antibiotics and accounted for 30.7, 23.6 and 16.0 % of all antibiotics, respectively. More recently available broad-spectrum antibiotics such as azithromycin and quinolones were more frequently prescribed in private clinics. Antibiotic prescribing rates are high in both public and private primary care settings in Malaysia, especially in the latter. This study provides evidence of excessive and inappropriate antibiotic prescribing for self-limiting conditions. These data highlights the needs for more concerted interventions targeting both prescribers and public. Improvement strategies should focus on reducing

    In sub-Saharan Africa (SSA), severe febrile illness accounts for a large majority of medical admissions. SSA patients may also suffer from cachexia and organ dysfunction resulting from tuberculosis, hepatitis B, and hypertension. It is hard to tell how these conditions influence the pharmacokinetics (PK) of antibiotics in this population. The aim of this systematic review was to summarize antibiotic PK data of SSA adult patient populations to clarify whether inappropriate drug concentrations that may also lead to antimicrobial resistance are likely to occur. An electronic search was conducted in Ovid MEDLINE, Embase, and the African Index Medicus collecting studies from 1946 to May 2016. Reviewers independently selected studies reporting outcome data on volume of distribution (V), clearance, and half-life. Relevant information was abstracted and quality assessed. Twelve studies were selected, addressing 6 antibiotic classes. There were 6 studies on fluoroquinolones and 1 on β-lactam antibiotics. Nine out of 12 originated from South Africa and 6 of those dealt with intensive care unit (ICU) populations. The quality of most studies was low. Studies on amikacin, teicoplanin, and ertapenem (n = 4) displayed a pattern of a large V with low drug concentrations. Fluoroquinolone PK changes were less prominent and more diverse whereas the probability of pharmacodynamic target attainment was low for the treatment of tuberculosis in South Africa. Interindividual variability of V was high for 10/12 studies. Antibiotic PK data of SSA adult patient populations are scarce, but disease-induced inappropriate drug concentrations do occur. Data from non-ICU, severely ill patients, and β-lactam data are particularly lacking, whereas β-lactam antibiotics are commonly used, and typically vulnerable to disease-induced PK changes. Studies investigating the PK and pharmacodynamics of β-lactam antibiotics in severely ill, adult SSA patient populations are needed to improve local

    Use of antibiotics has been correlated with increasing rates of resistance. Pharmacists are ideally positioned as front line health care providers to limit indiscriminate antibiotic use and promote the safe and effective administration of these medications. The aim of this project was to assess pharmacists' opinions relating to antibiotic utilization in the community setting. Doha, Qatar. Community and primary care pharmacists were invited to participate in one of three focus groups or a semi-structured interview at Qatar University or at their site of employment. A total of 22 community and primary care pharmacists participated in this study. Interviews were facilitated using a focus group guide, were recorded, and later transcribed. Transcripts were reviewed for recurring themes and coded using Nvivo software for qualitative research. Pharmacists' perceptions. Five major themes emerged from a series of focus groups and interviews. Themes which recurred across interview groups included: misconceptions and inappropriate practices by patients and healthcare providers, currently implemented strategies, perceived barriers, ways to overcome perceived barriers, and targets for improvement of antibiotic use in Qatar. The greatest need, as identified by pharmacists in this study was increased knowledge of the general population about appropriate antibiotic use through various educational interventions. Pharmacists report a number of misconceptions and inappropriate practices relating to antibiotic use in Qatar by patients and healthcare providers. Education to improve knowledge of appropriate antibiotic use is needed. Despite recognition of these issues, barriers are preventing pharmacists from implementing strategies to improve antibiotic use in Qatar.

    Full Text Available Bacterial infections are raising serious concern across the globe. The effectiveness of conventional antibiotics is decreasing due to global emergence of multi-drug-resistant (MDR bacterial pathogens. This process seems to be primarily caused by an indiscriminate and inappropriate use of antibiotics in non-infected patients and in the food industry. New classes of antibiotics with different actions against MDR pathogens need to be developed urgently. In this context, this review focuses on several ways and future directions to search for the next generation of safe and effective antibiotics compounds including antimicrobial peptides, phage therapy, phytochemicals, metalloantibiotics, LPS and efflux pump inhibitors to control the infections caused by MDR pathogens.

    Objective was to study the type of bacterial pathogen causing urinary tract infection in children at Aseer Central Hospital, southwestern Saudi Arabia and their antimicrobial resistance patterns. A retrospective study of all the urine cultures carried out on the children in the period from January 2003 to December 2006, for a total of 4 years were reviewed at the bacteriology laboratory, Aseer Central Hospital, southwestern region of Saudi Arabia. Their antimicrobial resistances as well as sensitivities were also analyzed. A total of 464 urine cultures were identified. Escherichia coli constitutes the most common pathogen isolated 37.3%, followed by Klebsiella 16.4% and Pseudomonas species 15.7%. In general, there was a significant increase in the resistance rates of different bacterial pathogens to different antibiotics. In spite of an increase in the resistance rates of bacterial pathogens causing UTI, ceftriaxone, imipenem and to some extent Azactam are appropriate for initial empirical intravenous therapy in UTI. In patients with uncomplicated UTI not requiring hospitalization, Nalidixic acid and Nitrofurantoin can be used as oral treatment. (author)

    Full Text Available Abstract Background Inappropriate antibiotic use promotes resistance. Antibiotics are generally not indicated for upper respiratory infections (URIs. Our objectives were to describe patterns of URI treatment and to identify patient and provider factors associated with antibiotic use for URIs. Methods This study was a cross-sectional analysis of medical and pharmacy claims data from the Pennsylvania Medicaid fee-for-service program database. We identified Pennsylvania Medicaid recipients with a URI office visit over a one-year period. Our outcome variable was antibiotic use within seven days after the URI visit. Study variables included URI type and presence of concurrent acute illnesses and chronic conditions. We considered the associations of each study variable with antibiotic use in a logistic regression model, stratifying by age group and adjusting for confounders. Results Among 69,936 recipients with URI, 35,786 (51.2% received an antibiotic. In all age groups, acute sinusitis, chronic sinusitis, otitis, URI type and season were associated with antibiotic use. Except for the oldest group, physician specialty and streptococcal pharyngitis were associated with antibiotic use. History of chronic conditions was not associated with antibiotic use in any age group. In all age groups, concurrent acute illnesses and history of chronic conditions had only had fair to poor ability to distinguish patients who received an antibiotic from patients who did not. Conclusion Antibiotic prevalence for URIs was high, indicating that potentially inappropriate antibiotic utilization is occurring. Our data suggest that demographic and clinical factors are associated with antibiotic use, but additional reasons remain unexplained. Insight regarding reasons for antibiotic prescribing is needed to develop interventions to address the growing problem of antibiotic resistance.

    Inappropriate antibiotic use for acute respiratory tract infections is common in primary health care, but distinguishing serious from self-limiting infections is difficult, particularly in low-resource settings. We assessed whether C-reactive protein point-of-care testing can safely reduce antibiotic use in patients with non-severe acute respiratory tract infections in Vietnam. We did a multicentre open-label randomised controlled trial in ten primary health-care centres in northern Vietnam. Patients aged 1-65 years with at least one focal and one systemic symptom of acute respiratory tract infection were assigned 1:1 to receive either C-reactive protein point-of-care testing or routine care, following which antibiotic prescribing decisions were made. Patients with severe acute respiratory tract infection were excluded. Enrolled patients were reassessed on day 3, 4, or 5, and on day 14 a structured telephone interview was done blind to the intervention. Randomised assignments were concealed from prescribers and patients but not masked as the test result was used to assist treatment decisions. The primary outcome was antibiotic use within 14 days of follow-up. All analyses were prespecified in the protocol and the statistical analysis plan. All analyses were done on the intention-to-treat population and the analysis of the primary endpoint was repeated in the per-protocol population. This trial is registered under number NCT01918579. Between March 17, 2014, and July 3, 2015, 2037 patients (1028 children and 1009 adults) were enrolled and randomised. One adult patient withdrew immediately after randomisation. 1017 patients were assigned to receive C-reactive protein point-of-care testing, and 1019 patients were assigned to receive routine care. 115 patients in the C-reactive protein point-of-care group and 72 patients in the routine care group were excluded in the intention-to-treat analysis due to missing primary endpoint.

    BACKGROUND: Prolonging post-operative antibiotic treatment beyond 3 days does not seem to reduce the incidence of post-operative abscess formation or wound infection after surgery for complicated appendicitis. The route of administration seems to be based on an empirical basis. Using enteral...... antibiotics could reduce length of stay and reduce overall costs. We aimed to examine whether treatment with enteral antibiotics during the first three post-operative days is non-inferior to intravenous antibiotics regarding intra-abdominal abscess formation or wound infection after surgery for complicated...... of surgery. Route of antibiotic administration for the first three post-operative days was registered for all patients. RESULTS: A total of 1141 patients were included in the study. The overall risk of developing an intra-abdominal abscess was 6.7% (95% CI 5.2%; 8.1%), and the risk of wound infection was 1...

    The aim of this study was to identify clinical risk factors for antimicrobial resistances and multidrug resistance (MDR) in urinary tract infections (UTI) in an emergency department in order to improve empirical therapy. UTI cases from an emergency department (ED) during January 2013 and June 2015 were analyzed. Differences between patients with and without resistances towards Ciprofloxacin, Piperacillin with Tazobactam (Pip/taz), Gentamicin, Cefuroxime, Cefpodoxime and Ceftazidime were analyzed with Fisher's exact tests. Results were used to identify risk factors with logistic regression modelling. Susceptibility rates were analyzed in relation to risk factors. One hundred thirty-seven of four hundred sixty-nine patients who met the criteria of UTI had a positive urine culture. An MDR pathogen was found in 36.5% of these. Overall susceptibility was less than 85% for standard antimicrobial agents. Logistic regression identified residence in nursing homes, male gender, hospitalization within the last 30 days, renal transplantation, antibiotic treatment within the last 30 days, indwelling urinary catheter and recurrent UTI as risk factors for MDR or any of these resistances. For patients with no risk factors Ciprofloxacin had 90%, Pip/taz 88%, Gentamicin 95%, Cefuroxime 98%, Cefpodoxime 98% and Ceftazidime 100% susceptibility. For patients with 1 risk factor Ciprofloxacin had 80%, Pip/taz 80%, Gentamicin 88%, Cefuroxime 78%, Cefpodoxime 78% and Ceftazidime 83% susceptibility. For 2 or more risk factors Ciprofloxacin drops its susceptibility to 52%, Cefuroxime to 54% and Cefpodoxime to 61%. Pip/taz, Gentamicin and Ceftazidime remain at 75% and 77%, respectively. We identified several risk factors for resistances and MDR in UTI. Susceptibility towards antimicrobials depends on these risk factors. With no risk factor cephalosporins seem to be the best choice for empiric therapy, but in patients with risk factors the beta-lactam penicillin Piperacillin with Tazobactam

    Inappropriate prescribing of antibiotics by health care professionals is a worldwide concern. This study evaluated the knowledge and practices of dental practitioners in the city of Shiraz, Islamic Republic of Iran regarding their therapeutic use of antibiotics for patients with dentoalveolar infections. Of 219 (48.6%) dentists responding to the questionnaire more than 40% would prescribe antibiotics for localized fluctuant swelling and for problems for which antibiotics are not required according to good practice guidelines (acute pulpitis, chronic apical infection, periodontal abscess, chronic gingivitis, chronic periodontitis, pericoronitis and dry socket). A majority correctly prescribed antibiotics for acute periapical infection (77.2%), cellulitis (75.3%) and acute ulcerated gingivitis (63.0%). Amoxicillin was the most frequently prescribed antibiotic for all clinical conditions but there was a wide variation in dosage, frequency and duration for all antibiotics used. Guidelines on rational antibiotic use are needed for dental practitioners in the Islamic Republic of Iran.

    Enterobacteriaceae are common pathogens in pneumonia, sepsis and urinary tract infection (UTI). Though rare, carbapenem resistance (CRE) among these organisms complicates efforts to ensure adequate empiric antimicrobial therapy. In turn this negatively impacts such outcomes as mortality and hospital costs. We explored proportion of total costs represented by antibiotics, 30-day readmission rates, and per-day costs of inadequate antimicrobial coverage among patients with Enterobacteriaceae pneumonia, sepsis and/or UTI in the context of inappropriate (IET) vs. appropriate empiric (non-IET) therapy and carbapenem resistance (CRE) vs. susceptibility (CSE). We conducted a retrospective cohort study in the Premier Research database (2009-2013) of 175 US hospitals. We included all adult patients admitted with a culture-confirmed UTI, pneumonia, or sepsis as principal diagnosis, or as a secondary diagnosis in the setting of respiratory failure. Patients with hospital acquired infections or transfers from other acute facilities were excluded. IET was defined as failure to administer an antibiotic therapy in vitro active against the culture-confirmed pathogen within 2 days of admission. Among 40,137 patients with Enterobacteriaceae infections (54.2% UTI), 4984 (13.2%) received IET. CRE (3.1%) was more frequent in patients given IET (13.0%) than non-IET (1.6%, p  $750 to hospital costs. Both CRE and IET were associated with an increased risk of readmission within 30 days.

    Full Text Available Abstract Background Antibiotic overuse and misuse for upper respiratory tract infections in children is widespread and fuelled by public attitudes and expectations. This study assessed knowledge, beliefs, and practices regarding antibiotic use for these paediatric infections among children's caregivers' in Trinidad and Tobago in the English speaking Caribbean. Methods In a cross-sectional observational study, by random survey children's adult caregivers gave a telephone interview from November 1998 to January 1999. On a pilot-tested evaluation instrument, respondents provided information about their knowledge and beliefs of antibiotics, and their use of these agents to treat recent episodes ( Results Of the 417 caregivers, 70% were female and between 18–40 years, 77% were educated to high school and beyond and 43% lived in urban areas. Two hundred and forty nine (60% respondents scored high (≥ 12 on antibiotic knowledge and 149 (34% had used antibiotics in the preceding year. More caregivers with a high knowledge score had private health insurance (33%, (p Conclusions In Trinidad and Tobago, caregivers scoring low on antibiotic knowledge have erroneous beliefs and use antibiotics inappropriately. Children in their care receive antibiotics for upper respiratory tract infections without visiting a health clinic or a physician. Educational interventions in the community on the consequences of inappropriate antibiotic use in children are recommended. Our findings emphasise the need to address information, training, legislation and education at all levels of the drug delivery system towards discouraging self-medication with antibiotics in children.

    Adult long-term care (LTC) facilities have high rates of antibiotic use, raising concerns about antimicrobial resistance. Few studies have examined antibiotic use in paediatric LTC facilities. To describe antibiotic use in three paediatric LTC facilities and to describe the factors associated with use. A retrospective cohort study was conducted from September 2012 to December 2015 in three paediatric LTC facilities. Medical records were reviewed for demographics, healthcare-associated infections (HAIs), antimicrobial use and diagnostic testing. Logistic regression was used to identify predictors for antibiotic use. The association between susceptibility testing results and appropriate antibiotic coverage was determined using Chi-squared test. Fifty-eight percent (413/717) of residents had at least one HAI, and 79% (325/413) of these residents were treated with at least one antibiotic course, totalling 2.75 antibiotic courses per 1000 resident-days. Length of enrolment greater than one year, having a neurological disorder, having a tracheostomy, and being hospitalized at least once during the study period were significantly associated with receiving antibiotics when controlling for facility (all P facilities is widespread. There is further need to assess antibiotic use in paediatric LTC facilities. Evaluation of the adverse outcomes associated with inappropriate antibiotic use, including the prevalence of resistant organisms in paediatric LTC facilities, is critical.

    Objective: To isolate and identify the causative pathogen, antibiotic sensitivity testing and success rate of empirical antibiotic therapy in pyogenic meningitis. Study Design: Analytical study. Place and Duration of Study: The Children's Hospital and Institute of Child Health, Lahore, Pakistan, from March to July 2012. Methodology: The study was performed on 72 culture positive meningitis cases in children less than 15 years of age. This therapy was evaluated by monitoring the patient's clinical picture for 14 - 21 days. The collected data was analyzed by Chi-square test. Results: Seventeen different bacteria were isolated. The most commonly occurring bacteria were coagulase negative Staphylococci (25%), E. coli (12.5%), Klebsiella pneumoniae (8.3%), Streptococcus pneumoniae (8.3%) and Pseudomonas aeruginosa (8.3%). All the bacteria were sensitive to vancomycin (96.7%), meropenem (76.7%), amikacin (75%), ciprofloxacin (65.3%), chloramphenicol (46.5%), ceftazidime (44.2%), cefepime (41.9%), co-amoxiclav (38.0%), oxacillin (34.8%), cefotaxime (21.4%), penicillin (20.7%), ceftriaxone (18.6%), cefuroxime (14%) and ampicillin (6.9%). The combination of sulbactam and cefoperazone showed antimicrobial sensitivity of 81.4%. The success rate of empirical antibiotic therapy was 91.7%. Conclusion: It was found that Gram negative bacteria were the major cause of pyogenic meningitis. Mostly there were resistant strains against all commonly used antibiotics except vancomycin. All empirical antibiotic therapies were found to be most successful. (author)

    Full Text Available Background and objectives As a common infectious disease in childhood, shigellosis has a variety of seasonal and microbiologic patterns and there is a concerning trend of resistance in various parts of the world and even a single country. Inappropriate empiric therapy for any acute episode of gastroenteritis, which might be based on lab studies, could potentially lead to even further resistance. In this report, the erythrocyte sedimentation rate was studied in patients with acute gastroenteritis. Methods Medical records of 117 patients were reviewed in this study. The mean and standard deviation of some of the acute phase inflammatory indicators were compared in two groups of shigellosis and viral gastroenteritides using independent samples t test. Results The mean age of the patients was 49 months, and almost half of them were male. Shigella sonnei was the commonest species isolated from these patients. Shigellosis was found to be more frequent during August to October. After 2001, resistance to ampicillin and cotrimoxazole was observed in 75% and 90% of isolates respectively. A few cases were resistant to third generation of cephalosporins (< 3%. In shigellosis, the erythrocyte sedimentation rate was significantly higher than viral gastroenteritis. Conclusion Empiric use of cotrimoxazole is no longer recommended in children suspicious of contracting shigellosis in Tehran. To avoid unnecessary prescription of antibiotics for acute gastroenteritis, a normal result of erythrocyte sedimentation rate might be helpful.Keywords: Gastroenteritis, Shigella, Bacterial Antibiotic Resistance, Antibiotics, Erythrocyte Sedimentation Rate

    Antibiotic resistance is a major threat to public health worldwide. As the healthcare sector's use of antibiotics is an important contributor to the development of resistance, it is crucial that physicians only prescribe antibiotics when needed and that they choose narrow-spectrum antibiotics, which act on fewer bacteria types, when possible. Inappropriate use of antibiotics is nonetheless widespread, not least for respiratory tract infections (RTI), a common reason for antibiotics prescriptions. We examine if pay-for-performance (P4P) presents a way to influence primary care physicians' choice of antibiotics. During 2006-2013, 8 Swedish healthcare authorities adopted P4P to make physicians select narrow-spectrum antibiotics more often in the treatment of children with RTI. Exploiting register data on all purchases of RTI antibiotics in a difference-in-differences analysis, we find that P4P significantly increased the share of narrow-spectrum antibiotics. There are no signs that physicians gamed the system by issuing more prescriptions overall. © 2017 The Authors Health Economics Published by John Wiley & Sons Ltd.

    Full Text Available Upper respiratory tract infection (URTI is considered to be the most common reason for children’s visits to emergency departments or outpatient clinics. The misuse and overuse of antibiotics are currently major public health problems worldwide. This study aimed to assess Saudi parents’ knowledge, attitude, and practice (KAP regarding the use of antibiotics in URTIs in children.This cross-sectional study was conducted in Saudi Arabia using a previously validated questionnaire, which was distributed using Twitter. A total of 385 individuals completed the questionnaire. For the majority of the participants (77%, physicians were the primary source of information regarding the use of antibiotics. Forty-four percent of parents agreed that most URTIs are caused by viruses, and 81% were aware that inappropriate use of antibiotics leads to the development of antibiotic resistance. Fever was the primary symptom (27% that led parents to ask for prescriptions for antibiotics. Although women had a higher attitude score (p = 0.01, there was no difference between genders regarding knowledge and practice. Older participants (41 years or more had a lower attitude score (p = 0.02. Furthermore, participants with five children or more had lower attitude and practice scores (p = 0.006, 0.04, respectively. Participants who lived in large cities had greater knowledge compared to the inhabitants of small cities (p = 0.01. In conclusion, the findings of this study demonstrated that most of the participants were educated but lacked knowledge regarding antibiotic use in URTIs in children. This lack of knowledge led to inappropriate attitude and practice. Thus, launching public educational campaigns and encouraging physicians to educate parents regarding the proper use of antibiotics are recommended.

    Antibiotics have not only saved lives and improved outcomes, but they also influence the evolving microbiome. This review summarizes reports on neonatal infections and variation in antibiotic utilization, discusses the emergence of resistant organisms, and presents data from human neonates and animal models demonstrating the impact of antibiotics on the microbiome, and how microbiome alterations impact health. The importance of antibiotic stewardship is also discussed. Infections increase neonatal morbidity and mortality. Furthermore, the clinical presentation of infections can be subtle, prompting clinicians to empirically start antibiotics when infection is a possibility. Antibiotic-resistant infections are a growing problem. Cohort studies have identified extensive center variations in antibiotic usage and associations between antibiotic exposures and outcomes. Studies of antibiotic-induced microbiome alterations and downstream effects on the developing immune system have increased our understanding of the mechanisms underlying the associations between antibiotics and adverse outcomes. The emergence of resistant microorganisms and recent evidence linking antibiotic practice variations with health outcomes has led to the initiation of antibiotic stewardship programs. The review encourages practitioners to assess local antibiotic use with regard to local microbiology, and to adopt steps to reduce infections and use antibiotics wisely.

    Inappropriate prescribing is highly prevalent in older people and is a major healthcare concern because of its association with negative healthcare outcomes including adverse drug events, related morbidity and hospitalization. With changing population demographics resulting in increasing proportions of older people worldwide, improving the quality and safety of prescribing in older people poses a global challenge. To date a number of different strategies have been used to identify potentially inappropriate prescribing in older people. Over the last two decades, a number of criteria have been published to assist prescribers in detecting inappropriate prescribing, the majority of which have been explicit sets of criteria, though some are implicit. The majority of these prescribing indicators pertain to overprescribing and misprescribing, with only a minority focussing on the underprescribing of indicated medicines. Additional interventions to optimize prescribing in older people include comprehensive geriatric assessment, clinical pharmacist review, and education of prescribers as well as computerized prescribing with clinical decision support systems. In this review, we describe the inappropriate prescribing detection tools or criteria most frequently cited in the literature and examine their role in preventing inappropriate prescribing and other related healthcare outcomes. We also discuss other measures commonly used in the detection and prevention of inappropriate prescribing in older people and the evidence supporting their use and their application in everyday clinical practice.

    Full Text Available Background: Antibiotics are important in the management and prophylaxis of infections in patients at a risk of experiencing microbial disease. Uses of systemic antibiotics in dentistry are limited since management of acute dental conditions is primarily based upon extraction of teeth or extirpation of the pulp. However, the literature provides evidence of inappropriate prescribing practices by practitioners, due to a number of factors from inadequate knowledge to social factors. Aim: The aim was to assess the therapeutic prescription of antibiotics in the dental office. Materials and Methods: In the current study, 42 faculty members of two dental colleges in the same vicinity were included. A questionnaire was drafted and sent to the dentists to collect data pertaining to the conditions in which antibiotics were prescribed and most commonly prescribed antibiotic. Results: During the study period, 42 faculty members from various departments in the institutes were surveyed, of which 41 questionnaires were completely filled. Amoxicillin was the most commonly prescribed antibiotic followed by other amoxicillin combinations; Metronidazole was most widely prescribed antibiotic for anaerobic infections. Conclusion: We have entered an era where cures may be few due to increasing microbial resistance. The biggest force for change will be if all practicing dentists looked at their prescribing and made it more rational.

    This randomized, dual-center study compared the efficacy and safety of piperacillin-tazobactam (PTZ) and imipenem-cilastatin (IMP) in hematopoietic stem cell transplantation (HSCT) recipients with febrile neutropenia. HSCT recipients with febrile neutropenia were randomized into two groups receiving either PTZ or IMP as initial empiric antibiotic. Endpoints were defervescence rate after empiric antibiotic for 48 h, success at end of therapy, and side effects. Defervescence within 48 h after empiric antibiotic was observed in 46 patients with PTZ (75.4%) and 59 patients with IMP (95.2%) (p = 0.002). Ten patients (10/46) in the PTZ group and two patients (2/59) in the IMP group switched empiric antibiotics due to recurrent fever (p = 0.005). Success of initial antibiotic with modification was achieved in 34 patients with PTZ (55.7%) and 53 patients with IMP (85.5%) at the end of therapy (p = 0.001). To treat the bacteremia, seven of 10 patients in the PTZ group and one of eight patients in the IMP group needed to switch the empiric antibiotic (p = 0.025). Compared with PTZ, IMP had more gastrointestinal adverse events (p = 0.045). This study demonstrates that IMP had better efficacy than PTZ as an empiric antibiotic for febrile neutropenia in the HSCT setting, but with more gastrointestinal side reactions. © 2015 John Wiley & Sons A/S.

    Clinical Decision Support Systems (CDSS) incorporating justifications, updating and adjustable recommendations can considerably improve the quality of healthcare. We propose a new approach to the design of CDSS for empiric antibiotic prescription, based on implementation of the deeper medical reasoning used by experts in the development of clinical practice guidelines (CPGs), to deduce the recommended antibiotics. We investigated two methods ("exclusion" versus "scoring") for reproducing this reasoning based on antibiotic properties. The "exclusion" method reproduced expert reasoning the more accurately, retrieving the full list of recommended antibiotics for almost all clinical situations. This approach has several advantages: (i) it provides convincing explanations for physicians; (ii) updating could easily be incorporated into the CDSS; (iii) it can provide recommendations for clinical situations missing from CPGs.

    Antimicrobial resistance is a public health challenge supplemented by inappropriate prescribing, especially for an upper respiratory tract infection in primary care. Patient/carer expectations have been identified as one of the main drivers for inappropriate antibiotics prescribing by primary care physicians. The aim of this study was to understand who is more likely to expect an antibiotic for an upper respiratory tract infection from their doctor and the reasons underlying it. This study used a sequential mixed methods approach: a nationally representative cross sectional survey ( n  = 1509) and four focus groups. The outcome of interest was expectation and demand for an antibiotic from a doctor when presenting with a cold or flu. The study found 19.5 % of survey respondents reported that they would expect the doctor to prescribe antibiotics for a cold or flu. People younger than 65 years of age, those who never attended university and those speaking a language other than English at home were more likely to expect or demand antibiotics for a cold or flu. People who knew that 'antibiotics don't kill viruses' and agreed that 'taking an antibiotic when one is not needed means they won't work in the future' were less likely to expect or demand antibiotics. The main reasons for expecting antibiotics were believing that antibiotics are an effective treatment for a cold or flu and that they shortened the duration and potential deterioration of their illness. The secondary reason centered around the value or return on investment for visiting a doctor when feeling unwell. Our study found that patients do not appear to feel they have a sufficiently strong incentive to consider the impact of their immediate use of antibiotics on antimicrobial resistance. The issue of antibiotic resistance needs to be explained and reframed as a more immediate health issue with dire consequences to ensure the success of future health campaigns.

    Increasing antibiotic resistance limits treatment options for gonorrhea. We examined the impact of a hypothetical point-of-care (POC) test reporting antibiotic susceptibility profiles on slowing resistance spread. A mathematical model describing gonorrhea transmission incorporated resistance emergence probabilities and fitness costs associated with resistance based on characteristics of ciprofloxacin (A), azithromycin (B), and ceftriaxone (C). We evaluated time to 1% and 5% prevalence of resistant strains among all isolates with the following: (1) empiric treatment (B and C), and treatment guided by POC tests determining susceptibility to (2) A only and (3) all 3 antibiotics. Continued empiric treatment without POC testing was projected to result in >5% of isolates being resistant to both B and C within 15 years. Use of either POC test in 10% of identified cases delayed this by 5 years. The 3 antibiotic POC test delayed the time to reach 1% prevalence of triply-resistant strains by 6 years, whereas the A-only test resulted in no delay. Results were less sensitive to assumptions about fitness costs and test characteristics with increasing test uptake. Rapid diagnostics reporting antibiotic susceptibility may extend the usefulness of existing antibiotics for gonorrhea treatment, but ongoing monitoring of resistance patterns will be critical. © The Author 2017.

    Infections with resistant Enterobacter spp. are increasingly described, yet data on outcomes associated with these infections are limited. A retrospective cohort study was conducted to investigate outcomes of hospitalized patients with third-generation cephalosporin-resistant (CR) Enterobacter bacteremia. Cephalosporin resistance was detected using cefotaxime and cefpodoxime. Patients with Enterobacter spp. bacteremia from January 2006 through February 2008 defined the population. We defined cases as those with CR isolates; controls were patients with bacteremia due to non-CR isolates. Treatment failure was defined as persistence of the presenting signs of infection 72 h after initial culture collection. Of the 95 Enterobacter cases identified, 31 (33%) were CR. CR cases were significantly associated with treatment failure (odds ratio (OR) 2.81, 95% confidence interval (CI) 1.14-6.94). This association was not seen after adjustment for age, simplified acute physiology score (SAPS II), and inappropriate empiric antibiotic therapy. Inappropriate empiric therapy (adjusted OR 3.86, 95% CI 1.32-11.31) and SAPS II score (adjusted OR 1.09, 95% CI 1.02-1.16) were significantly associated with treatment failure in the multivariate analysis. Third-generation cephalosporin-resistant Enterobacter bacteremia is associated with treatment failure due to receipt of inappropriate empiric antibiotic therapy and severity of illness.

    Inappropriate use of antibiotics has resulted in a dramatic increase of antimicrobial resistance in developing countries. We examined knowledge, attitudes, and practices of antibiotic use in three Asian countries. A nationwide cross-sectional study of teachers in large cities of Yemen, Saudi Arabia, and Uzbekistan was conducted. A random sample of 1,200 teachers was selected in each country. Data were collected through a questionnaire-based survey and then analyzed using descriptive and multivariate statistical methods. The prevalence of non-prescription antibiotic use ranged from 48% in Saudi Arabia to 78% in Yemen and Uzbekistan. Pharmacies were the main source of non-prescribed antibiotics. The most common reasons for antibiotic use were cough (40%) and influenza (34%). Forty-nine percent of respondents discontinued antibiotics when they felt better. Although awareness of the dangers of antibiotic use correlated inversely with self-medication, understanding of the appropriate use of antibiotics was limited. The prevalence of antibiotic self-medication in the educated adult population in the studied countries was found to be alarmingly high. Effective strategies involving regulatory enforcement prohibiting sales of antibiotics without prescription should be implemented along with educational interventions for health professionals and the public.

    The purpose of this study was to evaluate the use of empirical vancomycin for patients with neutropenic fever (NF) with regard to adherence to treatment guidelines. Adult patients with a diagnosis of neutropenia, who met the definition of NF as per treatment guidelines, were identified. Use of vancomycin was evaluated as part of empirical therapy and again after 72h. Outcomes were assessed using descriptive statistics, the Chi-square or Fisher's exact test, and univariate exact logistic regression analyses. Sixty-four patients were included. Overall, inappropriate empirical vancomycin use was observed in more than 30% of patients. Of 35 patients with indications for empirical vancomycin, only 68% received it. At 72h, appropriate vancomycin continuation, de-escalation, or discontinuation occurred in 21 of 33 patients. On univariate regression, hematological malignancy was associated with appropriate empirical vancomycin prescribing, whether initiating or withholding (odds ratio 4.0, 95% confidence interval 1.31-12.1). No variable was independently associated with inappropriate continuation at 72h. There is poor guideline adherence to vancomycin prescribing as empirical therapy and at 72-h reassessment in patients with NF. Further efforts are needed to foster a more rational use of vancomycin in patients with NF. Copyright © 2018. Published by Elsevier Ltd.

    The gut microbiota is a key player in many physiological and pathological processes occurring in humans. Recent investigations suggest that the efficacy of some clinical approaches depends on the action of commensal bacteria. Antibiotics are invaluable weapons to fight infectious diseases. However, by altering the composition and functions of the microbiota, they can also produce long-lasting deleterious effects for the host. The emergence of multidrug-resistant pathogens raises concerns about the common, and at times inappropriate, use of antimicrobial agents. Here we review the most recently discovered connections between host pathophysiology, microbiota, and antibiotics highlighting technological platforms, mechanistic insights, and clinical strategies to enhance resistance to diseases by preserving the beneficial functions of the microbiota.

    Adherence to antimicrobial guidelines for empiric antibiotic prescribing in community-acquired pneumonia (CAP) has been reported to be worryingly low. We conducted a review of empiric antibiotic prescribing for sixty consecutive adult patients admitted to the Mercy University Hospital with a diagnosis of CAP. When analysed against local antimicrobial guidelines, guideline concordant empiric antibiotics were given in only 48% of cases, lower than the average rate in comparable studies. Concordance was 100% in cases where the CURB-65 pneumonia severity assessment score, on which the guidelines are based, was documented in the medical notes. The use of excessively broad spectrum and inappropriate antibiotics is a notable problem. This study supports the theory that lack of knowledge regarding pneumonia severity assessment tools and unfamiliarity with therapeutic guidelines are key barriers to guideline adherence, which remains a significant problem despite increased focus on antimicrobial stewardship programs in Ireland

    Antibiotics are frequently prescribed and extremely valuable drugs, because they are curative. However, their often incorrect use is the main reason for the increase of multiresistant pathogens. Inappropriate prescription of broad spectrum antibiotics for skin and soft tissue infections favors the selection and spread of multiresistant bacteria not only in the skin, but also in remote visceral organs (e.g. in the intestines), due to their systemic distribution and effects in the body (so-called collateral damage). For this reason basic knowledge and special prudence when using antibiotics are just as desirable as an awareness of responsibility for the public welfare. This article intends to convey basic knowledge on the indications and selection of suitable antibiotics as well as on the development of bacterial resistance and it gives recommendations for allergological procedures when patients report alleged drug reactions to antibiotics. Systemic antibiotics for soft tissue infections are indicated when the infection spreads within the tissue so that it is no longer accessible for local antiseptics. In addition to the clinical symptoms, important parameters are high blood sedimentation rates (BSR) and high levels of C-reactive protein (CRP), leukocytosis with neutrophilia and fever (not always present in elderly or immunosuppressed patients). Certain constellations, such as the presence of severe underlying diseases, perfusion disorders or a particular localization (e.g. infection of the face) may necessitate early or parenteral administration. There is no need for systemic administration of antibiotics for uncomplicated wounds without soft tissue infections. Due to their curative effects, the decisive criterion for the use of antibiotics is their sufficient antimicrobial efficacy at the site of infection. An inappropriate administration increases both the selection pressure and costs of treatment and can have fatal consequences in serious situations. In

    Full Text Available Objective: This study sought to explore the knowledge and attitudes of parents on the use of antibiotics among children that could serve as baseline data and provide further insight in planning and developing strategies for local health education purposes. Methods: A cross-sectional survey involving 500 parents who attended community pharmacies in Tetovo, Republic of Macedonia, was conducted using a self-administered questionnaire from October 2013 to January 2014. The questionnaire included demographics, knowledge and attitude statements of parents towards antibiotics. The data collected were analyzed using SPSS program, version 19.0. Descriptive statistics was used to summarize the data. In all statistical analyses, a p-value of <0.05 was considered statistically significant. Results: Nearly 40% of the parents demonstrated a moderate level of knowledge. The highest correct response in the knowledge part was the awareness of parents in using antibiotics to treat a bacterial infection (61.2%. However, most of the parents did not know that antibiotics cannot cure viral infections (59.6%. About 48.2% of the parents were aware of the antibiotic resistance as s result of the overuse. Concerning attitudes, 60.8% reported keeping any leftover antibiotics, 77.0% agreed that taking antibiotics when having cold symptoms could help their children recover faster, while, 74.6% wrongly agreed with the statement of appropriate use of antibiotics for prophylaxis’ measure. Conclusions: This study has documented the main areas that merit attention when parental knowledge on antibiotic use for their children is the concern, reflecting in some inappropriate attitudes as well. The findings highlight the need to devise effective interventions to decrease misconceptions regarding antibiotic use and to increase parents’ awareness for the risks of inappropriate use of antibiotics in children specifically and in the community at large.

    To generate epidemiological information regarding antibiotic use and antimicrobial resistance (AMR) in targeted communities for use by the Thailand AMR Containment and Prevention Program. A survey of antibiotics sold by 215 grocery stores and retail shops located in the target communities was done by the local people who were instructed to purchase specified antibiotics and to present to such stores and shops with symptoms of sore throat, backache, common cold, acute diarrhea, inflamed uterus, and dysuria. The purchased drugs were then identified and recorded. Contamination of extended-spectrum β-lactamase (ESBL)-producing E. coli was identified in 174 samples of foods and open water sources collected from the target communities. Carriage of ESBL-producing E. coli in gastrointestinal tracts of 534 adults living in the target communities was performed by stool sample culture. One thousand three hundred one patients with upper respiratory infection (URI) and 235 patients with acute diarrhea who attended the tambon health promoting hospitals located in the target communities were monitored for their clinical outcomes of treatments. The patients with URI and acute diarrhea with no indication of antibiotic received symptomatic treatments as appropriate and they were followed via telephone contact every few days until all symptoms related to URI and acute diarrhea disappeared. The data were analyzed by descriptive statistics. Antibiotics were sold to the local people who were presenting with common ailments at many grocery stores and retail shops in their respective communities. In almost all cases, antibiotics were inappropriately given. Overall prevalence of ESBL-producing E. coli contamination in foods and open water sources was 26.4%. ESBL-producing E. coli was isolated from fresh meat and open water sources in many samples. Overall prevalence of ESBL-producing E. coli carriage in gastrointestinal tracts of the adults cultured was 66.5%. All patients with URI and

    Introduction. Community-acquired urinary tract infections (CAUTIs) are usually treated empirically. Geographical variations in etiologic agents and their antibiotic sensitivity patterns are common. Knowledge of antibiotic resistance trends is important for improving evidence-based recommendations for empirical treatment of UTIs. Our aim was to determine the major bacterial etiologies of CAUTIs and their antibiotic resistance patterns in a cosmopolitan area of Cameroon for comparison with prescription practices of local physicians. Methods. We performed a cross-sectional descriptive study at two main hospitals in Yaoundé, collecting a clean-catch mid-stream urine sample from 92 patients having a clinical diagnosis of UTI. The empirical antibiotherapy was noted, and identification of bacterial species was done on CLED agar; antibiotic susceptibility testing was performed using the Kirby-Bauer disc diffusion method. Results. A total of 55 patients had samples positive for a UTI. Ciprofloxacin and amoxicillin/clavulanic acid were the most empirically prescribed antibiotics (30.9% and 23.6%, resp.); bacterial isolates showed high prevalence of resistance to both compounds. Escherichia coli (50.9%) was the most common pathogen, followed by Klebsiella pneumoniae (16.4%). Prevalence of resistance for ciprofloxacin was higher compared to newer quinolones. Conclusions. E. coli and K. pneumoniae were the predominant bacterial etiologies; the prevalence of resistance to commonly prescribed antibiotics was high.

    Most antibiotics obtained by in vitro screening with antibacterial activity have inappropriate properties as medicines due to their toxicity and pharmacodynamics in animal bodies. Thus, evaluation of the therapeutic effects of these samples using animal models is essential in the crude stage. Mammals are not suitable for therapeutic evaluation of a large number of samples due to high costs and ethical issues. We propose the use of silkworms (Bombyx mori) as model animals for screening therapeutically effective antibiotics. Silkworms are infected by various pathogenic bacteria and are effectively treated with similar ED(50) values of clinically used antibiotics. Furthermore, the drug metabolism pathways, such as cytochrome P450 and conjugation systems, are similar between silkworms and mammals. Silkworms have many advantages compared with other infection models, such as their 1) low cost, 2) few associated ethical problems, 3) adequate body size for easily handling, and 4) easier separation of organs and hemolymph. These features of the silkworm allow for efficient screening of therapeutically effective antibiotics. In this review, we discuss the advantages of the silkworm model in the early stages of drug development and the screening results of some antibiotics using the silkworm infection model.

    Full Text Available Introduction: Most human orofacial infections originate from odontogenic infections and prescribing antibiotics has become a ubiquitous phenomenon. The World Health Organization (WHO has recognized the inappropriate, indiscriminate, and irrational use of antibiotics leading to antibiotic resistance as a global problem. Objective: The objective of this survey is to compare the antibiotic prescription pattern and the awareness of antibiotic resistance among Bachelor of Dental Surgery (BDS practitioners and pediatric dentists. Materials and methods: A hundred BDS practitioners and 100 pediatric dentists included in the study were given a questionnaire containing both open-ended and closed-ended questions. The questionnaire comprised information pertaining to antibiotic prescription for most common oral conditions, commonly prescribed antibiotics, their dosage, etc. Results: The majority of the practitioners prescribed antibiotics for managing oral diseases. On comparing the prescription patterns between the BDS practitioners and pediatric dentists, there was an overprescription in the BDS group for many conditions, which was statistically significant. Amoxicillin was the most commonly prescribed drug in both the groups. In the presence of an anaerobic infection, the most preferred drug was a combination of amoxicillin and clavulanic acid with metronidazole. With regard to the duration of antibiotic prescription, 74% BDS practitioners prescribed antibiotics as a 3-day course and 60% pediatric dentists resorted to a 5-day course, which was statistically significant. The awareness regarding antibiotic prophylaxis and antibiotic resistance was found to be adequate in both the groups. However, there was a general lack of awareness with regard to the guidelines for antibiotic prescribing in both the groups. Conclusion: Practitioners should prescribe antibiotics in accordance with the guidelines to curb antibiotic resistance, an emerging public health

    Full Text Available Background/Aim. The most common cause of acute dental infections are oral streptococci and anaerobe bacteria. Acute dentoalveolar infections are usually treated surgically in combination with antibiotics. Empirical therapy in such infections usually requires the use of penicillin-based antibiotics. The aim of this study was to investigate the clinical efficiency of amoxicillin and cefalexin in the empirical treatment of acute odontogenic abscess and to assess the antimicrobial susceptibility of the isolated bacteria in early phases of its development. Methods. This study included 90 patients with acute odontogenic abscess who received surgical treatment (extraction of a teeth and/or abscess incision and were divided into three groups: two surgicalantibiotic groups (amoxicillin, cefalexin and the surgical group. In order to evaluate the effects of the applied therapy following clinical symptoms were monitored: inflammatory swelling, trismus, regional lymphadentytis and febrility. In all the patients before the beginning of antibiotic treatment suppuration was suched out of the abscess and antibiotic susceptibility of isolated bacteria was tested by using the disk diffusion method. Results. The infection signs and symptoms lasted on the average 4.47 days, 4.67 days, and 6.17 days in the amoxicillin, cefalexin, and surgically only treated group, respectively. A total of 111 bacterial strains were isolated from 90 patients. Mostly, the bacteria were Gram-positive facultative anaerobs (81.1%. The most common bacteria isolated were Viridans streptococci (68/111. Antibiotic susceptibility of isolated bacteria to amoxicillin was 76.6% and cefalexin 89.2%. Conclusion. Empirical, peroral use of amoxicillin or cefalexin after surgical treatment in early phase of development of dentoalveolar abscess significantly reduced the time of clinical symptoms duration in the acute odontogenic infections in comparison to surgical treatment only.

    Over-use of antibiotics for acute respiratory infections (ARIs) increases antimicrobial resistance, treatment costs, and side effects. Patient desire for antibiotics contributes to over-use. To explore whether a point-of-care interactive computerized education module increases patient knowledge and decreases desire for antibiotics. Bilingual (English/Spanish) interactive kiosks were available in 8 emergency departments as part of a multidimensional intervention to reduce antibiotic prescribing for ARIs. The symptom-tailored module included assessment of symptoms, knowledge about ARIs (3 items), and desire for antibiotics on a 10-point visual analog scale. Multivariable analysis assessed predictors of change in desire for antibiotics. Of 686 adults with ARI symptoms, 63% initially thought antibiotics might help. The proportion of patients with low (1-3 on the scale) desire for antibiotics increased from 22% pre-module to 49% post-module (pknowledge about antibiotics and ARIs. Learning correlated with changes in personal desire for antibiotics. By reducing desire for antibiotics, point-of-care interactive educational computer technology may help decrease inappropriate use for antibiotics for ARIs. Copyright © 2011 Elsevier Ireland Ltd.

    Full Text Available BACKGROUND: The appropriate use of antibiotics prophylaxis in the prevention and reduction in the incidence of surgical site infection is widespread. This study evaluates the appropriateness of the prescription of antibiotics prophylaxis prior to surgery amongst hospitalized patients in the geographic area of Avellino, Caserta, and Naples (Italy and the factors associated with a poor adherence. METHODS: A sample of 382 patients admitted to 23 surgical wards and undergoing surgery in five hospitals were randomly selected. RESULTS: Perioperative antibiotic prophylaxis was appropriate in 18.1% of cases. The multivariate logistic regression analysis showed that patients with hypoalbuminemia, with a clinical infection, with a wound clean were more likely to receive an appropriate antibiotic prophylaxis. Compared with patients with an American Society of Anesthesiologists (ASA score ≥4, those with a score of 2 were correlated with a 64% reduction in the odds of having an appropriate prophylaxis. The appropriateness of the timing of prophylactic antibiotic administration was observed in 53.4% of the procedures. Multivariate logistic regression model showed that such appropriateness was more frequent in older patients, in those admitted in general surgery wards, in those not having been underwent an endoscopic surgery, in those with a higher length of surgery, and in patients with ASA score 1 when a score ≥4 was chosen as the reference category. The most common antibiotics used inappropriately were ceftazidime, sultamicillin, levofloxacin, and teicoplanin. CONCLUSIONS: Educational interventions are needed to improve perioperative appropriate antibiotic prophylaxis.

    Limited data exist on optimal empiric oral antibiotic treatment for outpatients with cellulitis in areas with a high prevalence of community-associated methicillin-resistant Staphylococcus aureus (MRSA) infections. We conducted a 3-year retrospective cohort study of outpatients with cellulitis empirically treated at a teaching clinic of a tertiary-care medical center in Hawaii. Patients who received more than 1 oral antibiotic, were hospitalized, or had no follow-up information were excluded. Treatment success rates for empiric therapy were compared among commonly prescribed antibiotics in our clinic: cephalexin, trimethoprim-sulfamethoxazole, and clindamycin. Risk factors for treatment failure were evaluated using multivariate logistic regression analysis. Of 544 patients with cellulitis, 405 met the inclusion criteria. The overall treatment success rate of trimethoprim-sulfamethoxazole was significantly higher than the rate of cephalexin (91% vs 74%; P<.001), whereas clindamycin success rates were higher than those of cephalexin in patients who had subsequently culture-confirmed MRSA infections (P=.01), had moderately severe cellulitis (P=.03), and were obese (P=.04). Methicillin-resistant S. aureus was recovered in 72 of 117 positive culture specimens (62%). Compliance and adverse drug reaction rates were not significantly different among patients who received these 3 antibiotics. Factors associated with treatment failure included therapy with an antibiotic that was not active against community-associated MRSA (adjusted odds ratio 4.22; 95% confidence interval, 2.25-7.92; P<.001) and severity of cellulitis (adjusted odds ratio 3.74; 95% confidence interval, 2.06-6.79; P<.001). Antibiotics with activity against community-associated MRSA, such as trimethoprim-sulfamethoxazole and clindamycin, are preferred empiric therapy for outpatients with cellulitis in the community-associated MRSA-prevalent setting.

    Antimicrobial resistance is a worldwide threat to public health. Acute respiratory tract infections are the main reason for antibiotic prescribing in the Spanish paediatric population. The aim of the study was to describe the frequency of antibiotic prescription and their pattern of use in acute respiratory tract infections diagnosed in children in Primary Care in Aragón (Spain). A study was conducted over a 1-year period on children between 0 and 14 years-old, recording all episodes of acute otitis, acute pharyngotonsillitis, non-specific upper respiratory infection, and acute bronchitis. The proportion of episodes within each diagnosis receiving an antibiotic prescription was calculated, and the prescribing pattern was determined. Half (50%) of the children in Aragón were diagnosed with a respiratory tract infection during the study period. Non-specific upper respiratory infection was the most frequent diagnosis. An antibiotic was prescribed in 75% of pharyngotonsillitis episodes, 72% of otitis, 27% of bronchitis, and 16% of non-specific upper respiratory infections. Broad spectrum antibiotics, mainly amoxicillin and amoxicillin-clavulanic, were predominantly prescribed. Antibiotic prescribing in respiratory tract infections in children was generally high, and the choice of antibiotics was probably inappropriate in a high percentage of cases. Therefore an improvement in antibiotic prescribing in children appears to be needed. Copyright © 2014 Asociación Española de Pediatría. Published by Elsevier España, S.L.U. All rights reserved.

    TREAT is a computerized decision support system aimed at improving empirical antibiotic treatment of inpatients with suspected bacterial infections. It contains a model that balances, for each antibiotic choice (including 'no antibiotics'), expected benefit and expected costs. The main benefit afforded by appropriate, empirical, early antibiotic treatment in moderate to severe infections is a better chance of survival. Each antibiotic drug was consigned three cost components: cost of the drug and administration; cost of side effects; and costs of future resistance. 'No treatment' incurs no costs. The model worked well for decision support. Its analysis showed, yet again, that for moderate to severe infections, a model that does not include costs of resistance to future patients will always return maximum antibiotic treatment. Two major moral decisions are hidden in the model: how to take into account the limited life-expectancy and limited quality of life of old or very sick patients; and how to assign a value for a life-year of a future, unnamed patient vs. the present, individual patient. © 2010 The Authors.

    Surgical site infections (SSI) are the most common surgical complication. Perioperative antibiotics can reduce SSI when used properly. Despite guidelines from The American College of Obstetrics and Gynecology, non-indicated antibiotic use is widespread which exposes women to unnecessary risks. This study represents a quality improvement analysis assessing surgeon compliance with established guidelines regarding antibiotic use in gynaecological surgery. This is a single centre, retrospective study examining gynaecological procedures over two years. Cases were identified using Current Procedure Terminology codes. Perioperative antibiotics were used contrary to published guidelines in 199 of 1046 cases. Three variables were independently associated with inappropriate administration of perioperative antibiotics: entrance into abdominal cavity, higher EBL, and longer procedures. Impact statement Overuse of antibiotics has unintended consequences including allergic sequelae, extended length of hospital stay, increased healthcare costs, and the formation of antibiotic-resistant organisms. Antibiotic stewardship programmes have been shown to reduce the number of resistant pathogens, decrease incidence of Clostridium difficile colitis, and decrease length of hospital stay without increasing infection rates. Further outcomes-based research is needed regarding the use of antibiotic stewardship programmes in gynaecological surgery.

    Full Text Available Introduction. Community-acquired urinary tract infections (CAUTIs are usually treated empirically. Geographical variations in etiologic agents and their antibiotic sensitivity patterns are common. Knowledge of antibiotic resistance trends is important for improving evidence-based recommendations for empirical treatment of UTIs. Our aim was to determine the major bacterial etiologies of CAUTIs and their antibiotic resistance patterns in a cosmopolitan area of Cameroon for comparison with prescription practices of local physicians. Methods. We performed a cross-sectional descriptive study at two main hospitals in Yaoundé, collecting a clean-catch mid-stream urine sample from 92 patients having a clinical diagnosis of UTI. The empirical antibiotherapy was noted, and identification of bacterial species was done on CLED agar; antibiotic susceptibility testing was performed using the Kirby-Bauer disc diffusion method. Results. A total of 55 patients had samples positive for a UTI. Ciprofloxacin and amoxicillin/clavulanic acid were the most empirically prescribed antibiotics (30.9% and 23.6%, resp.; bacterial isolates showed high prevalence of resistance to both compounds. Escherichia coli (50.9% was the most common pathogen, followed by Klebsiella pneumoniae (16.4%. Prevalence of resistance for ciprofloxacin was higher compared to newer quinolones. Conclusions. E. coli and K. pneumoniae were the predominant bacterial etiologies; the prevalence of resistance to commonly prescribed antibiotics was high.

    the knowledge, attitude, and behavior regarding antibiotics among the general population of Poland. Inappropriate antibiotic use is still highly prevalent in Poland, although a positive trend in behavioral change was observed after the educational campaigns. Additional didactic and systematic education campaigns regarding appropriate antibiotic use are needed and the use of the Internet as an education tool should be enhanced.

    Community-acquired pneumonia (CAP) continues to be associated with significant mortality and morbidity. As with other infectious diseases, in recent years there has been a marked increase in resistance to the antibiotics commonly used against the pathogens that cause CAP. Antimicrobial stewardship denotes coordinated interventions to improve and measure the appropriate use of antibiotics by encouraging the selection of optimal drug regimens. Areas covered: Several elements can be applied to antibiotic stewardship strategies for CAP in order to maintain or improve patient outcomes. In this regard, antibiotic de-escalation, duration of antibiotic treatment, adherence to CAP guidelines recommendations about empirical treatment, and switching from intravenous to oral antibiotic therapy may each be relevant in this context. Antimicrobial stewardship strategies, such as prospective audit with intervention and feedback, clinical pathways, and dedicated multidisciplinary teams, that have included some of these elements have demonstrated improvements in antimicrobial use for CAP without negatively affecting clinical outcomes. Expert commentary: Although there are a limited number of randomized clinical studies addressing antimicrobial stewardship strategies in CAP, there is evidence that antibiotic stewardship initiatives can be securely applied, providing benefits to both healthcare systems and patients.

  1. Resistance Elasticity of Antibiotic Demand in Intensive Care.

    The emergence and spread of antimicrobial resistance (AMR) is still an unresolved problem worldwide. In intensive care units (ICUs), first-line antibiotic therapy is highly standardized and widely empiric while treatment failure because of AMR often has severe consequences. Simultaneously, there is a limited number of reserve antibiotics, whose prices and/or side effects are substantially higher than first-line therapy. This paper explores the implications of resistance-induced substitution effects in ICUs. The extent of such substitution effects is shown in a dynamic fixed effect regression analysis using a panel of 66 German ICUs with monthly antibiotic use and resistance data between 2001 and 2012. Our findings support the hypothesis that demand for reserve antibiotics substantially increases when resistance towards first-line agents rises. For some analyses the lagged effect of resistance is also significant, supporting the conjecture that part of the substitution effect is caused by physicians changing antibiotic choices in empiric treatment by adapting their resistance expectation to new information on resistance prevalence. The available information about resistance rates allows physicians to efficiently balance the trade-off between exacerbating resistance and ensuring treatment success. However, resistance-induced substitution effects are not free of charge. These effects should be considered an indirect burden of AMR. Copyright © 2016 John Wiley & Sons, Ltd.

    Antibiotics are often prescribed inappropriately to infants and young children, with potentially adverse effects on the developing gut microbiota and related metabolic processes. We review evidence from 17 epidemiologic studies suggesting that antibiotic exposure during critical periods of early development may influence weight gain and the development of obesity. Complementary research in both humans and rodents indicates that gut microbiota play a key role in this process, although further research is needed to confirm and characterize the causal mechanisms involved. Obesity is a complex and multifactorial condition; thus, a multipronged prevention strategy will be required to curb the current obesity epidemic. Evidence to date suggests this strategy should include the judicious use of antibiotics, especially in early life when the developing gut microbiota is particularly susceptible to perturbations with long-lasting implications for metabolic programming and obesity risk. © 2017 Nestec Ltd., Vevey/S.

    Invasive Listeria monocytogenes infections carry a high mortality despite antibiotic treatment. The rareness of the infection makes it difficult to improve antibiotic treatment through randomized clinical trials. This observational study investigated clinical features and outcome of invasive L. monocytogenes infections including the efficacy of empiric and definitive antibiotic therapies. Demographic, clinical and biochemical findings, antibiotic treatment and 30-day mortality for all episodes of L. monocytogenes bacteraemia and/or meningitis were collected by retrospective medical record review in the North Denmark Region and the Capital Region of Denmark (17 hospitals) from 1997 to 2012. Risk factors for 30-day all-cause mortality were assessed by logistic regression. The study comprised 229 patients (median age: 71 years), 172 patients had bacteraemia, 24 patients had meningitis and 33 patients had both. Significant risk factors for 30-day mortality were septic shock (OR 3.0, 95% CI 1.4-6.4), altered mental state (OR 3.6, 95% CI 1.7-7.6) and inadequate empiric antibiotic therapy (OR 3.8, 95% CI 1.8-8.1). Cephalosporins accounted for 90% of inadequately treated cases. Adequate definitive antibiotic treatment was administered to 195 patients who survived the early period (benzylpenicillin 72, aminopenicillin 84, meropenem 28, sulfamethoxazole/trimethoprim 6, and piperacillin/tazobactam 5). Definitive antibiotic treatment with benzylpenicillin or aminopenicillin resulted in a lower 30-day mortality in an adjusted analysis compared with meropenem (OR 0.3; 95% CI 0.1-0.8). In conclusion, inadequate empiric antibiotic therapy and definitive therapy with meropenem were both associated with significantly higher 30-day mortality.

    Full Text Available Excessive antibiotic consumption and misuse is one of the main factors responsible for the emergence of antibiotic-resistant bacteria and has been associated with increased health care costs. Active intervention is necessary in changing antimicrobial prescribing practices. The Infection Control Committee and the administration of our hospital decided to implement an antibiotic stewardship program beginning in January 2016 in order to reduce inappropriate antibiotic use and to combat antibiotic resistance through improved prescribing practices. The antimicrobial stewardship team includes an ID specialist, physicians, infection control nurses, a microbiologist and a pharmacist who are responsible for the implementation of the program. Preauthorization by an ID specialist and prospective review is necessary for all pharmacy orders of antibiotics under restriction. Pre-intervention, we collected Pharmacy and hospital data regarding antibiotic consumption and numbers of patient-days for the years 2013-2015. We calculated antibiotic use in Defined Daily Doses (DDDs/100 patient-days. After one year, the antibiotic stewardship program was effective in reducing consumption of most antibiotics. The result of the implementation of the program in our hospital was a reduction about 17% of antibiotic DDDs/100 patient-days and about 21% of the antibiotic cost/100 patient-days. Education is an essential element of our program in order to influence prescribing behavior. Lectures and brochures are used to supplement strategies. Antibiotic stewardship programs have been shown from many studies to improve patient outcomes, reduce antibiotic resistance and save money.

    Introduction Antimicrobial resistance (AMR) is a challenging global and public health issue, raising bioethical challenges, considerations and strategies. Objectives This research protocol presents a conceptual model leading to formulating an empirically based bioethics framework for antibiotic use, AMR and designing ethically robust strategies to protect human health. Methods Mixed methods research will be used and operationalized into five substudies. The bioethical framework will encompass and integrate two theoretical models: global bioethics and ethical decision-making. Results Being a study protocol, this article reports on planned and ongoing research. Conclusions Based on data collection, future findings and using a comprehensive, integrative, evidence-based approach, a step-by-step bioethical framework will be developed for (i) responsible use of antibiotics in healthcare and (ii) design of strategies to decrease AMR. This will entail the analysis and interpretation of approaches from several bioethical theories, including deontological and consequentialist approaches, and the implications of uncertainty to these approaches.

    The lack of patient knowledge about their medication is considered to be one of the main reasons for an inappropriate use. This study the level of knowledge in patients about their prescribed antibiotic, and describes some of the factors related to this. A cross-sectional, descriptive and observational study with an analytical component. SITE: A community pharmacy in Murcia. The study form was offered to all customers who arrived to obtain antibiotics while the study was taking place. A validated form was used to determined the level of knowledge was a validated form. A total of 126 patients, most of them women, with an average age of 44.6 years were included. Half of the study population had no knowledge which could ensure the correct use of the antibiotic they were taking. The «process of use» of the medication was the best known dimension by the study population, followed by the «therapeutic aim». The dimension related to the «safety» of the medication was the one with the lowest values. After a logistic regression, a link between the knowledge of the antibiotic and the «know the name of the antibiotic» (p=.05; r=2.15) and the «number of antibiotic the patient takes» (p=.02; r=0.30) variables. The results show that there is a certain lack of information on the use of antibiotics by the study sample. Thes results could help to show the way to follow in future studies, targeted to meet the need of information. Copyright © 2013 Elsevier España, S.L.U. All rights reserved.

    This study was conducted to investigate the bacteriology and associated patterns of antibiotic resistance Fournier gangrene. Patients with Fournier's gangrene from 2008 to 2012 were identified from the computerized database in a medical center in southern Taiwan. The medical records of all patients with Fournier's gangrene were reviewed retrospectively. There were 61 microorganisms, including 60 bacteria and one Candida spp, isolated from clinical wound specimens from 32 patients. The most common isolates obtained were Streptococcus spp. (n=12), Peptoniphilus spp. (n=8), Staphylococcus aureus (n=7), Escherichia coli (n=7), and Klebsiella pneumoniae (n=7). Among 21 strains of gram-negative bacilli, five (23.8%) were resistant to fluoroquinolones, and three isolates were resistant to ceftriaxone. Two E. coli strains produced extended-spectrum beta-lactamase. Four of the seven S. aureus isolates were methicillin-resistant. Among 15 anaerobic isolates, nine (60%) were resistant to penicillin, and eight (53.3%) were resistant to clindamycin. Four (26.7%) isolates were resistant to metronidazole. The only independent risk factor associated with mortality was inappropriate initial antibiotic treatment (p=0.021). Antibiotic-resistant bacteria are emerging in the clinical setting of Fournier gangrene. Clinicians should use broad-spectrum antibiotics initially to cover possible antibiotic-resistant bacteria.

    Urinary Tract Infections (UTIs) are of the most common bacterial diseases worldwide. We investigate the antibiotic susceptibility patterns of Escherichia coli (E. coli) strains isolated from pediatric patients with community acquired urinary tract infection (UTI) to find a clinical guidance for choosing a right empirical antibiotic in these patients. In this cross sectional study, 100 urine specimens which were positive for E. coli had been investigated for antibiotics susceptibility pattern. The susceptibility to Co-trimoxazol (25μg), Amikacin (30μg), Ceftriaxone (30μg), Nalidixic Acid (30μg), Cefixime (5μg), and Nitrofurantoin (300μg) tested with Disk diffusion agar and MIC determined with the E-test. Mean age of patients was 38 Months. Girls had greater proportion than boys (74 versus 26%). In Disk diffusion method, 26% of the isolates were susceptible to cotrimoxazole. Susceptibility to amikacin, ceftriaxone, nitrofurantoin, nalidixic acid and cefixime was 94%, 66%, 97%, 62% and 52%, respectively. By E-Test method and according to CLSI criteria susceptibility for co-trimoxazol, amikacin, ceftriaxone and nalidixic acid was 37%, 97%, 67% and 50%, respectively. The highest percentage of agreement between Disk diffusion and E-Test method was found for amikacin (96%) and the lowest percentage for co-trimoxazole (89%). Treatment failure, prolonged or repeated hospitalization, increased costs of care, and increased mortality are some consequence of bacterial resistance in UTIs. Misuse of antibiotics in each geographic location directly affects antibiotic resistance pattern. In the treatment of UTI, proper selection of antimicrobial agents should be relevant to the bacterial susceptibility testing surveillance. According to our results, amikacin as an injectable drug and nitrofurantoin as an oral agent could be used as a drug of choice in our region for children with UTIs.

    This study investigated risk factors of childhood urinary tract infection (UTI) associated with extended-spectrum β-lactamase (ESBL)-producing bacteria (ESBL-positive UTI) and evaluated antimicrobial resistance as well as empiric treatment of childhood UTI. The records of children with positive urine culture between 1 January 2008 and 31 December 2012 were evaluated. Patients with positive urine culture for ESBL-producing bacteria were defined as the ESBL-positive group, whereas patients of the same gender and similar age with positive urine culture for non-ESBL-producing bacteria were defined as the ESBL-negative group. Each ESBL-positive patient was matched with two ESBL-negative patients. The ESBL-positive and negative groups consisted of 154 and 308 patients, respectively. Potential risk factors for ESBL-positive UTI were identified as presence of underlying disease, clean intermittent catheterization (CIC), hospitalization, use of any antibiotic and history of infection in the last 3 months (P infection in the last 3 months were identified as independent risk factors. In the present study, 324 of 462 patients had empiric therapy. Empiric therapy was inappropriate in 90.3% of the ESBL-positive group and in 4.5% of the ESBL-negative group. Resistance to nitrofurantoin was similar between groups (5.1% vs 1.2%, P = 0.072); resistance to amikacin was low in the ESBL-positive group (2.6%) and there was no resistance in the ESBL-negative group. Clean intermittent catheterization, hospitalization and history of infection in the last 3 months should be considered as risk factors for ESBL-positive UTI. The combination of ampicillin plus amikacin should be taken into consideration for empiric therapy in patients with acute pyelonephritis who have the risk factors for ESBL-positive UTI. Nitrofurantoin seems to be a logical choice for the empiric therapy of cystitis. © 2016 Japan Pediatric Society.

    Tanzania introduced the accredited drug dispensing outlet (ADDO) program more than a decade ago. Previous evaluations have generally shown that ADDOs meet defined standards of practice better than non-accredited outlets. However, ADDOs still face challenges with overuse of antibiotics for acute respiratory infections (ARI) and simple diarrhea, which contributes to the emergence of drug resistance. This study aimed to explore the attitudes of ADDO owners and dispensers toward antibiotic dispensing and to learn how accreditation has influenced their dispensing behavior. The study used a qualitative approach. We conducted in-depth interviews with ADDO owners and dispensers in Ruvuma and Tanga regions where the government implemented the ADDO program under centralized and decentralized approaches, respectively; a secondary aim was to compare differences between the two regions. Findings indicate that the ADDO program has brought about positive changes in knowledge of dispensing practices. Respondents were able to correctly explain treatment guidelines for ARI and diarrhea. Almost all dispensers and owners indicated that unnecessary use of antibiotics contributed to antimicrobial resistance. Despite this knowledge, translating it to appropriate dispensing practice is still low. Dispensers' behavior is driven by customer demand, habit ("mazoea"), following inappropriate health facility prescriptions, and the need to make a profit. Although the majority of dispensers reported that they had intervened in situations where customers asked for antibiotics unnecessarily, they tended to give in to clients' requests. Small variations were noted between the two study regions; for example, some dispensers in Ruvuma reported sending clients with incorrect prescriptions back to the health facility, a practice that may reflect regional differences in ADDO implementation and in Integrated Management of Childhood Illness training. Dispensers in rural settings reported more challenges

    Urinary tract infection is certainly one of the most common childhood infections. Emerging resistance to the antibiotics is not unusual. Current hospitalization for children with urinary tract infection is reserved for severe or complicated cases. The aim of the present study was to determine the antibiotic resistance pattern among children with recurrent or complicated urinary tract infection. A retrospective study carried out at Prince Hashem hospital, Zarqa city, eastern Jordan and involved 336 episodes of culture proved urinary tract infection obtained from 121 patients with recurrent UTI, who used prophylactic antibiotics during the period from April 1, 2004 to December 31, 2006. The isolated microorganisms and there antibiotics susceptibility were studied. Seventy three patients (60.3%) were found to have some forms of urinary tract anomaly, significantly more prevalent among male children Purinary tract infection (64.3% vs. 16.6%, Purinary tract infection. Proteus, Pseudomonas and Candida spp. were more prevalent in patients with complicated (Presistant to most antibiotics tested. Pediatric urine culture isolates are becoming increasingly resistant to commonly used antibiotics. Empirical treatment with Trimethoprim-Sulfamethoxazole (TMP-SMX) or Cephalexin as the initial drug is ineffective. Nitrofurantoin and Nalidixic acid can be considered as the first line antibiotics for prophylaxis and or treatment of patients with recurrent UTI, while Meropenam and Ciprofloxacin can be used empirically in treating patients with complicated UTI.

    Antibiotics have always been considered one of the wonder discoveries of the 20th century. The use of penicillin by Flaming, opened up the golden era of antibiotics and now is hard to imagine the practice of medicine without antibiotics. Life-threatening infections, such as meningitis, endocarditis, bacteremic pneumonia sepsis, would again prove fatal. Also aggressive chemotherapy and transplant procedures would prove impossible. Another real wonder has been the rise of antibiotic resistance soon after the clinical use of penicillin in hospitals and communities. Several study demonstrated an excessive amount of antibiotic prescribing for communities patients and inpatients and in some hospital up to 50% of antibiotic usage is inappropriate: the benefits of antibiotic treatment come with the risk of antibiotic resistance development. In hospitals, infections caused by antibiotic-resistant bacteria are associated with higher mortality, morbidity and prolonged hospital stay compared with infections caused by antibiotic-susceptible bacteria. A variety of strategies has been proposed to reduce the cost and improve the quality of medication use. Education, guidelines and evidence based recommendations are considered to be essential elements of any program designed to influence prescribing behavior and can provide a foundation of knowledge that will enhance and increase the acceptance of stewardship strategies. Evidence-based recommendations, an approach to clinical practice helping to make decisions based on clinical expertise and on intimate knowledge of the individual patient's situations, beliefs, and priorities, enhance antimicrobial stewardship, that include appropriate selection, dosing, route, and duration of antimicrobial therapy can maximize clinical cure or prevention of infection while limiting the unintended consequences, such as the emergence of resistance, adverse drug events, and cost. These evidence-based guidelines are not a substitute for clinical

    Antibiotic stewardship programs (ASP) are designed to optimize antibiotic use in hospitals. Antibiotic consumption is one of the measures assessing the effects of ASPs. To evaluate the effect of an ASP on antibiotic consumption in our hospital and compare it to hospitals in Israel and worldwide. Between October 2012 and March 2013 an ASP was implemented in Rambam Hospital. The program included educational activities, publication of local guidelines for empirical antibiotic treatment, structured infectious diseases consultations, pre-authorization antibiotic restrictions and stop orders. We compared antibacterial antibiotic consumption in defined daily doses (DDD)/100 hospital days (HD) between the periods before (1/2010-3/2013) and after (4/2013-9/2014) implementing the ASP. The study was conducted in the medical departments, hematology, the intensive care unit (ICU) and all pediatric wards. Total antibiotic consumption before implementing the ASP was 96±11.2 DDD/100 HD in medical departments, 186.4±42.8 in the ICU and 185.5±59 in hematology; all values were higher than the worldwide-reported averages for these departments. Following the ASP, total antibiotic consumption decreased by 12% (p=0.008) in the medical departments and by 26% (p=0.002) in hematology, mostly due to reductions in non-restricted antibiotics. No significant changes were observed overall in the ICU and in pediatric wards. There was a significant reduction in consumption of vancomycin and carbapenems in all settings, the latter was reduced to nearly half. Amikacin use quadrupled in the medical departments. Implementation of an ASP lead to a reduction in non-restricted and restricted antibiotic consumption, especially carbapenems.

    Full Text Available Abstract Background Life-threatening infections present major challenges for health systems in Malawi and the developing world because routine microbiologic culture and sensitivity testing are not performed due to lack of capacity. Use of empirical antimicrobial therapy without regular microbiologic surveillance is unable to provide adequate treatment in the face of emerging antimicrobial resistance. This study was conducted to determine antimicrobial susceptibility patterns in order to inform treatment choices and generate hospital-wide baseline data. Methods Culture and susceptibility testing was performed on various specimens from patients presenting with possible infectious diseases at Kamuzu Central Hospital, Lilongwe, Malawi. Results Between July 2006 and December 2007 3104 specimens from 2458 patients were evaluated, with 60.1% from the adult medical service. Common presentations were sepsis, meningitis, pneumonia and abscess. An etiologic agent was detected in 13% of patients. The most common organisms detected from blood cultures were Staphylococcus aureus, Escherichia coli, Salmonella species and Streptococcus pneumoniae, whereas Streptococcus pneumoniae and Cryptococcus neoformans were most frequently detected from cerebrospinal fluid. Haemophilus influenzae was rarely isolated. Resistance to commonly used antibiotics was observed in up to 80% of the isolates while antibiotics that were not commonly in use maintained susceptibility. Conclusions There is widespread resistance to almost all of the antibiotics that are empirically used in Malawi. Antibiotics that have not been widely introduced in Malawi show better laboratory performance. Choices for empirical therapy in Malawi should be revised accordingly. A microbiologic surveillance system should be established and prudent use of antimicrobials promoted to improve patient care.

The results supported the current practice of using penicillin and erythromycin empirically for prophylaxis. The prediction of the most appropriate antibiotic for prophylaxis using dental plaque samples was most accurate when the minimum inhibitory concentration (MIC) of plaque isolates were used.

    In Spain, the inclusion of new antibiotics in hospital formularies is performed by the Infection Policy Committee or the Pharmacy and Therapeutic Committee, although now the decision is moving to a regional level. Criteria for the evaluation of new drugs include efficacy, safety and cost. For antimicrobial drugs evaluation it is necessary to consider local sensibility and impact in bacterial resistance to determinate the therapeutic positioning. There is compelling evidence that the use of antibiotics is associated with increasing bacterial resistance, and a great number of antibiotics are used incorrectly. In order to decrease the inappropriate use of antibiotics, several approaches have been proposed. Limiting the use of antimicrobials through formulary restrictions, often aimed at drugs with a specific resistance profile, shows benefits in improving antimicrobial susceptibilities and decreasing colonization by drug-resistant organisms. However, the restriction of one agent may result in the increased utilization of other agents. By using antibiotic cycling, the amount of antibiotics is maintained below the threshold where bacterial resistance develops, thus preserving highly efficient antibiotics. Unfortunately, cumulative evidence to date suggests that antibiotic cycling has limited efficacy in preventing antibiotic resistance. Finally, although there is still little clinical evidence available on antibiotic heterogeneity, the use of most of the existing antimicrobial classes could limit the emergence of resistance. This review summarizes information regarding antibiotic evaluation and available restrictive strategies to limit the use of antibiotics at hospitals with the aim of curtailing increasing antibiotic resistance.

    Background Inappropriate use of antibiotics is a public health problem of great concern. Objective To evaluate knowledge of antibiotics, race, gender and age as independent risk factors for self-medication. Setting Residents and population from different regions of Saudi Arabia. Methods We conducted a cross sectional survey study among residents. Data were collected between June 2014 to May, 2015 from 1310 participants and data were recorded anonymously. The questionnaire was randomly distributed by interview of participants and included sociodemographic characteristics, antibiotics knowledge, attitudes and behavior with respect to antibiotics usage. Main outcome measure Population aggregate scores on questions and data were analyzed using univariate logistic regression to evaluate the influence of variables on self-prescription of antibiotics. Results The response rate was 87.7 %. A cumulative 63.6 % of participants reported to have purchased antibiotics without a prescription from pharmacies; 71.1 % reported that they did not finish the antibiotic course as they felt better. The availability of antibiotics without prescription was found to be positively associated with self-medication (OR 0.238, 95 % CI 0.17-0.33). Of those who used prescribed or non-prescribed antibiotics, 44.7 % reported that they kept left-over antibiotics from the incomplete course of treatment for future need. Interestingly, 62 % of respondents who used drugs without prescription agreed with the statement that antibiotics should be access-controlled prescribed by a physician. We also found significant association between storage, knowledge/attitudes and education. Conclusions The overall level of awareness on antibiotics use among residents in Saudi Arabia is low. This mandates public health awareness intervention programs to be implemented on the use of antibiotics.

    To evaluate the knowledge, attitude and behaviours of university students on the use of antibiotics. A knowledge-attitude-practice questionnaire was developed and distributed to undergraduate students of Xi'an Jiaotong University, comprising 18 schools/colleges in Shaanxi Province, western China. Chi-square test and logistic regression analysis were applied to identify risk factors associated with self-medication with antibiotics. Of the 731 respondents (response rate = 73.1%), 294 (40.2%) had self-medicated with antibiotics in the past 6 months. Most of the antibiotics (59.2%) for self-medication were purchased without prescription in retail pharmacies. The median score of students' knowledge about antibiotics was 4 (IQR: 3-6) of a maximum possible score of 10. Students had moderately accurate beliefs towards antibiotics. More than half of the students (56.5%) were storing antibiotics frequently. During self-medication, 16.7% of students claimed to have experienced adverse reactions, and 30.6% had used antibiotics to prevent common colds. The majority preferred to use broad-spectrum antibiotics, and nearly half preferred intravenous antibiotics. Over 44% of students had changed antibiotic dosage, and 36.5% had switched to another antibiotic during the treatment course. Logistic regression analysis identified college and home town as independent risk factors for self-medication with antibiotics (P students had inadequate knowledge, moderately accurate beliefs and inappropriate practices concerning antibiotics, and a high rate of self-medication. This highlights the need for focused educational intervention and stricter governmental regulation concerning antibiotic use and sale in retail pharmacies. © 2014 John Wiley & Sons Ltd.

    DESIGNWe conducted a randomized, parallel, unblinded, superiority trial of a laboratory reporting intervention designed to reduce antibiotic treatment of asymptomatic bacteriuria (ASB).METHODSResults of positive urine cultures from 110 consecutive inpatients at 2 urban acute-care hospitals were randomized to standard report (control) or modified report (intervention). The standard report included bacterial count, bacterial identification, and antibiotic susceptibility information including drug dosage and cost. The modified report stated: "This POSITIVE urine culture may represent asymptomatic bacteriuria or urinary tract infection. If urinary tract infection is suspected clinically, please call the microbiology laboratory … for identification and susceptibility results." We used the following exclusion criteria: age pregnancy, presence of an indwelling urinary catheter, samples from patients already on antibiotics, neutropenia, or admission to an intensive care unit. The primary efficacy outcome was the proportion of appropriate antibiotic therapy prescribed.RESULTSAccording to our intention-to-treat (ITT) analysis, the proportion of appropriate treatment (urinary tract infection treated plus ASB not treated) was higher in the modified arm than in the standard arm: 44 of 55 (80.0%) versus 29 of 55 (52.7%), respectively (absolute difference, -27.3%; RR, 0.42; P = .002; number needed to report for benefit, 3.7).CONCLUSIONSModified reporting resulted in a significant reduction in inappropriate antibiotic treatment without an increase in adverse events.

    The aim of this study was to investigate farm-level economic and technical factors that are associated with the use of antibiotics on pig farms. Identification of such factors, like farm size and net farm result, may help to increase epidemiological knowledge and to specify farm advice and policy making to reduce inappropriate use of antibiotics. The study used over 300 farm-year records collected during 2004 to 2007 from pig farms in the Netherlands. Data included economic and technical factors as well as antibiotic administration. Data were statistically analyzed for factors associated with antibiotic use, both for fattening pig and sow farms (piglets only), separately. The response variable was the average number of daily dosages per average pig year. Statistical analysis was performed on 16 and 19 potential explanatory factors for the fattening pig and sow farms, respectively. The results showed that, both on the fattening pig and sow farms, the average use of antibiotics increased from 2004 to 2006, but decreased during 2007, but the effect of year was not significant (P > 0.05). Use of antibiotics varied between individual farms. Large farm repeatability for the use of antibiotics in the different years was found. Factors associated (P antibiotics included: farm system, number of pigs, and population density in the region of the farm (for sow farms only). As these factors are easy to collect and to register, they can be used to specify farm advice and investigation, as well as for policy making. The majority of the technical and economic factors were not significantly (P > 0.05) related to the on-farm use of antibiotics. Therefore, it is recommended to focus future research on the potential role of socioeconomic factors associated with antibiotic use on pig farms.

    Introduction. Multi-resistant Acinetobacter baumannii isolated from patients has become one of the most hazardous pathogens in health care settings. The aim of the study was to analyze pneumonia caused by Acinetobacter baumannii in patients hospitalized because of exacerbation of chronic obstructive pulmonary diseases (COPD), who were admitted to the Pulmonology Ward of the Masovian Specialistic Hospital in Radom (MSS). The incidence and drug sensitivity of these non-fermenting rods were evaluated, and compliance with antimicrobial procedure with the algorithm of the guidelines in applicable recommendations, was estimated. This should result in determining the local patterns of resistance and verifying therapeutic procedures in accordance with the assumptions of hospital antibiotic policy. In addition, the study examined the effectiveness of empiric and targeted therapy according to the clinical condition of the patient, and the eradication of A. baumannii, in comparison with the aggravating factors of the patient. Materials and Method. The retrospective study included 90 patients with exacerbation of COPD whose etiological factor of infection was A. baumannii, hospitalized in the Department of Pulmonology (MSS) in 2012-2016. Results. Studies were conducted on 90 patients with COPD exacerbation from which A. baumannii was isolated. Co-infections with other bacterial species among 41 patients were additionally noted. The majority of A. baumannii strains showed a high resistance (90%) to fluoroquinolones, ceftazidime, piperacillin/tazobactam. For strains causing a co-infection, drug resistance was successively 44-56%, 44%, 44%. All of patients received empirical therapy. The most commonly used drug was amoxicillin with a clavulanic acid, often combined with fluoroquinolone. This type of therapy was effective among 10% of patients. The mortality in this group was determined at 29%. Among 79% of patients with COPD, a targeted therapy was performed which proved to be

    Antibiotic resistance is a major health care problem mostly caused by the inappropriate use of antibiotics. At the root of the problem lies the current method for determination of bacterial susceptibility to antibiotics which requires overnight cultures. Physicians suspecting an infection usually prescribe an antibiotic without waiting for the results. This practice aggravates the problem of bacterial resistance. In this work, a rapid method of diagnosis and antibiogram for a bacterial infection was developed using Surface Enhanced Raman Spectroscopy (SERS) with silver nanoparticles. SERS spectra of three species of gram negative bacteria, Escherichia coli, Proteus spp., and Klebsiella spp. were obtained after 0 and 4 hour exposure to the seven different antibiotics. Even though the concentration of bacteria was low (2x105 cfu/ml), species classification was achieved with 94% accuracy using spectra obtained at 0 hours. Sensitivity or resistance to antibiotics was predicted with 81%-100% accuracy from spectra obtained after 4 hours of exposure to the different antibiotics. With the enhancement provided by SERS, the technique can be applied directly to urine or blood samples, bypassing the need for overnight cultures. This technology can lead to the development of rapid methods of diagnosis and antibiogram for a variety of bacterial infections.

    Full Text Available The article reports the results of an observational study conducted in 53 internal medicine departments of the Emilia Romagna region based on the answers to 54 questions administered in a questionnaire, submitted electronically, based on the type of center (large >250 beds, small <250 beds, laboratory equipment, management aspects, pharmacological and clinical/economic aspects and use of antibiotics in the empirical treatment of severe infections. The result is a snapshot of the existing situation which shows a substantial availability of resources and a good level of expertise in the field of infectious disease management, despite some areas still need improvement. It also highlights some differences in terms of procedures amongst large hospitals, where infectious diseases are treated by an ad hoc specialized staff, and the small ones, where the internist is generally involved, being responsible for both direct management of severe infections and giving advice to other departments (emergency or surgery. It emerged that, both in small and large hospitals, more discussion and continuous assessment are needed to apply the appropriate protocols based on reference checklists.

    Highlights: • We proposed a method to evaluate team communication characteristics based on social network analysis. • We compare team communication characteristics with the frequency of inappropriate communications. • Frequency of inappropriate communications were decreased when more operators perform the same types of role as others. • Frequency of inappropriate communications were decreased for teams who provide more number of acknowledgment. - Abstract: The characteristics of team communications are important since large process systems such as nuclear power plants, airline, and railways are operated by operating teams. In such situation, inappropriate communications can cause a lack of situational information and lead to serious consequences for the systems. As a result, the communication characteristics of operating teams should be understood in order to extract meaningful insights to address the nature of inappropriate communications. The purpose of this study was to develop a method to evaluate the characteristics of team communications based on social network analysis and compare them with the frequency of inappropriate communications. In order to perform the analysis, verbal protocol data, which were audio-visual recorded under training sessions by operating teams, were used and interfacing system loss of coolant accident scenarios were selected. As a result of the study, it was found that the frequency of inappropriate communications decreased when more operators perform the same types of role as other operators, since they can easily and effectively back up each other. Also, the frequency of inappropriate communication is decreased for teams which provide a relatively large communication content that acknowledge or confirm another communication content

    Currently hospitalization for children with urinary tract infections (UTIs) is reserved for severe or complicated cases. Changes may have taken place in the characteristics and causative uropathogens of hospital-treated community-acquired UTI. To study children hospitalized in a tertiary center with community-acquired UTI, compare Escherichia coli and non-E. coli UTI, define predictors for non-E. coli UTI and elucidate the appropriate therapeutic approach. A prospective clinical and laboratory study from 2001 through 2002 in a tertiary pediatric medical center. Patients were divided by results of the urine culture into E. coli and non-E. coli UTI groups, which were compared. Of 175 episodes of culture-proved UTI, 70 (40%) were caused by non-E. coli pathogens. Non-E. coli UTI was more commonly found in children who were male (P = 0.005), who had underlying renal abnormalities (P = 0.0085) and who had received antibiotic therapy in the prior month (P = 0.0009). Non-E. coli uropathogens were often resistant to antibiotics usually recommended for initial therapy for UTI, including cephalosporins and aminoglycosides; 19% were initially treated with inappropriate empiric intravenous antibiotics (compared with 2% for E. coli UTI, P = 0.0001), with a longer hospitalization. Current treatment routines are often inappropriate for hospitalized children with non-E. coli UTI, which is relatively common in this population. The defined risk factors associated with non-E. coli UTIs and its antimicrobial resistance patterns should be considered to improve empiric antibiotic therapy for these infections.

    The intestinal microbiome is a complex ecosystem of microorganisms that colonize the human gastrointestinal tract. The microbiome evolves rapidly in early life with contributions from diet, genetics and immunomodulatory factors. Changes in composition of the microbiota due to antibiotics may lead to negative long-term effects including obesity and diabetes mellitus, as evidenced by both animal and large human studies. Inappropriate exposures to antibiotics occur frequently in early childhood. Therefore, an evidence-based system of antimicrobial use should be employed by all providers, especially those who care for pediatric patients. This article explores the natural evolution of the intestinal microbiome from the perinatal period into early childhood, the effect of antibiotics on the microbial ecology, and the implications for future health and disease.

    Full Text Available Abstract Background Inappropriate medication use is a major healthcare issue for the elderly population. This study explored the prevalence of potentially inappropriate prescriptions (PIPs in long-term care in metropolitan Quebec. Methods A cross sectional chart review of 2,633 long-term care older patients of the Quebec City area was performed. An explicit criteria list for PIPs was developed based on the literature and validated by a modified Delphi method. Medication orders were reviewed to describe prescribing patterns and to determine the prevalence of PIPs. A multivariate analysis was performed to identify predictors of PIPs. Results Almost all residents (94.0% were receiving one or more prescribed medication; on average patients had 4.8 prescribed medications. A majority (54.7% of treated patients had a potentially inappropriate prescription (PIP. Most common PIPs were drug interactions (33.9% of treated patients, followed by potentially inappropriate duration (23.6%, potentially inappropriate medication (14.7% and potentially inappropriate dosage (9.6%. PIPs were most frequent for medications of the central nervous system (10.8% of prescribed medication. The likelihood of PIP increased significantly as the number of drugs prescribed increased (odds ratio [OR]: 1.38, 95% confidence interval [CI]: 1.33 – 1.43 and with the length of stay (OR: 1.78, CI: 1.43 – 2.20. On the other hand, the risk of receiving a PIP decreased with age. Conclusion Potentially inappropriate prescribing is a serious problem in the highly medicated long-term care population in metropolitan Quebec. Use of explicit criteria lists may help identify the most critical issues and prioritize interventions to improve quality of care and patient safety.

    Urinary tract infection (UTI) is the most common diagnosis made in prescribing antimicrobials in long-term care facilities (LTCF). The diagnostic criteria for UTI vary among institutions and prescribers. Our aim was to reduce the inappropriate use of antimicrobials in LTCFs. A team comprising infectious disease consultant, infection control nurse, and geriatrician visited all LTCFs for older persons (2,321 patients in 25 primary care hospitals and 39 nursing homes and dementia units) in the Central Finland Healthcare District (population 267,000) during 2004-2005. The site visits consisted of a structured interview concerning patients, ongoing systematic antimicrobials, and diagnostic practices for UTI. Following the visits, regional guidelines for prudent use of antimicrobials in LTCFs were published, and the use of antimicrobials was followed up by an annual questionnaire. The proportions of patients receiving antimicrobials in 2005, 2006, 2007, and 2008 were 19.9%, 16.9%, 16.2%, and 15.4%, respectively. Most of the antibiotics were used for UTI (range by year, 66.6%-81.1%). From 2005 through 2008, the proportion of patients on antibiotic prophylaxis for UTI decreased from 13% to 6%. The decrease was statistically significant in both types of settings. The visits and guidelines were associated with a reduction in the usage of antimicrobials. To sustain this, UTI surveillance and close collaboration between infection control experts and LTCFs are crucial.

    To analyse how antibiotics are imported, manufactured, distributed and regulated in Thailand. We gathered information, on antibiotic distribution in Thailand, in in-depth interviews - with 43 key informants from farms, health facilities, pharmaceutical and animal feed industries, private pharmacies and regulators- and in database and literature searches. In 2016-2017, licensed antibiotic distribution in Thailand involves over 700 importers and about 24 000 distributors - e.g. retail pharmacies and wholesalers. Thailand imports antibiotics and active pharmaceutical ingredients. There is no system for monitoring the distribution of active ingredients, some of which are used directly on farms, without being processed. Most antibiotics can be bought from pharmacies, for home or farm use, without a prescription. Although the 1987 Drug Act classified most antibiotics as "dangerous drugs", it only classified a few of them as prescription-only medicines and placed no restrictions on the quantities of antibiotics that could be sold to any individual. Pharmacists working in pharmacies are covered by some of the Act's regulations, but the quality of their dispensing and prescribing appears to be largely reliant on their competences. In Thailand, most antibiotics are easily and widely available from retail pharmacies, without a prescription. If the inappropriate use of active pharmaceutical ingredients and antibiotics is to be reduced, we need to reclassify and restrict access to certain antibiotics and to develop systems to audit the dispensing of antibiotics in the retail sector and track the movements of active ingredients.

    The widespread use of antibiotics in the past 80 years has saved millions of human lives, facilitated technological progress and killed incalculable numbers of microbes, both pathogenic and commensal. Human-associated microbes perform an array of important functions, and we are now just beginning to understand the ways in which antibiotics have reshaped their ecology and the functional consequences of these changes. Mounting evidence shows that antibiotics influence the function of the immune system, our ability to resist infection, and our capacity for processing food. Therefore, it is now more important than ever to revisit how we use antibiotics. This review summarizes current research on the short-term and long-term consequences of antibiotic use on the human microbiome, from early life to adulthood, and its effect on diseases such as malnutrition, obesity, diabetes, and Clostridium difficile infection. Motivated by the consequences of inappropriate antibiotic use, we explore recent progress in the development of antivirulence approaches for resisting infection while minimizing resistance to therapy. We close the article by discussing probiotics and fecal microbiota transplants, which promise to restore the microbiota after damage of the microbiome. Together, the results of studies in this field emphasize the importance of developing a mechanistic understanding of gut ecology to enable the development of new therapeutic strategies and to rationally limit the use of antibiotic compounds.

This survey dealt with questions that were subdivided into two main topics: dental emergency treatment approaches, and antibiotic prescription and information on lifelong learning program participation. The statistical analysis was conducted with a Χ2 test at a significance level of P<0.05. For irreversible pulpitis cases in vital teeth, most of the dental practitioners (65.3% preferred single-visit root canal treatments. For teeth presenting a periapical lesion, the preferred treatment approach was root canal treatment (91.5%. The rate of prescription of analgesics and antibiotics was 21.7% in untreated acute apical periodontitis cases and 41% in acute apical abscess cases. Frequently prescribed antibiotics were amoxicillin–clavulanate (61.8% and amoxicillin (46.5%. There was a tendency for practitioners to attend congresses as their years of professional practice increased (P<0.0001. There have been discrepancies between taught and observed practice. Educational initiatives are needed to prevent inappropriate prescription of antibiotics.Keywords: antibiotic prescription, endodontic emergency, survey, Turkey

    Full Text Available Abstract Background To reduce inappropriate admissions and stays with the application of an improvement cycle in patients admitted to a University Hospital. The secondary objective is to analyze the hospital cost saved by reducing inadequacy after the implementation of measures proposed by the group for improvement. Methods Pre- and post-analysis of a sample of clinical histories studied retrospectively, in which the Appropriateness Evaluation Protocol (AEP was applied to a representative hospital sample of 1350 clinical histories in two phases. In the first phase the AEP was applied retrospectively to 725 admissions and 1350 stays. The factors associated with inappropriateness were analysed together with the causes, and specific measures were implemented in a bid to reduce inappropriateness. In the second phase the AEP was reapplied to a similar group of clinical histories and the results of the two groups were compared. The cost of inappropriate stays was calculated by cost accounting. Setting: General University Hospital with 426 beds serving a population of 320,000 inhabitants in the centre of Murcia, a city in south-eastern Spain. Results Inappropriate admissions were reduced significantly: 7.4% in the control group and 3.2% in the intervention group. Likewise, inappropriate stays decreased significantly from 24.6% to 10.4%. The cost of inappropriateness in the study sample fell from 147,044 euros to 66,642 euros. The causes of inappropriateness for which corrective measures were adopted were those that showed the most significant decrease. Conclusions It is possible to reduce inadequacy by applying measures based on prior analysis of the situation in each hospital.

    Some children show anger inappropriate for the situation based on the predominant incentives, which is called context-inappropriate anger. Children need to attend to and interpret situational incentives for appropriate emotional responses. We examined associations of context-inappropriate anger with emotion recognition and attention problems in 43 preschoolers (42% male; M age = 55.1 months, SD = 4.1). Parents rated context-inappropriate anger across situations. Teachers rated attention problems using the Child Behavior Checklist-Teacher Report Form. Emotion recognition was ability to recognize emotional faces using the Emotion Matching Test. Anger perception bias was indicated by anger to non-anger situations using an adapted Affect Knowledge Test. 28% of children showed context-inappropriate anger, which correlated with lower emotion recognition (β = -.28) and higher attention problems (β = .36). Higher attention problems correlated with more anger perception bias (β = .32). This cross-sectional, correlational study provides preliminary findings that children with context-inappropriate anger showed more attention problems, which suggests that both "problems" tend to covary and associate with deficits or biases in emotion knowledge. © The Author(s) 2016.

    Judicious use of antibiotics is essential considering the growth of antimicrobial resistance and escalating costs in health care. This intervention study used treatment guidelines to improve antibiotic therapy by changing prescribing practice. A before-after intervention study was performed in a 550-bed tertiary care teaching hospital in Switzerland, with an additional follow-up analysis 1 year later. The pre-intervention phase included chart analysis of current antibiotic use in 100 consecutive patients from the representative medical and surgical wards included in the study. Treatment guidelines were defined, taking into account published guidelines, the local antibacterial sensitivity of the pathogens, and the hospital antibiotic formulary defined by the drug and therapeutics committee. The guidelines were presented to the medical residents on a pocket card. They were informed and educated by the pharmacist (intervention). In the post-intervention phase immediately after the instruction, and in the follow-up phase 1 year later, a prospective analysis of antibiotic prescription was performed by chart review of 100 antibacterial treatments in consecutive patients to detect changes in antibiotic prescribing (treatment) and to determine whether these changes were sustained. The pre-intervention review of antibiotic use showed the need for therapy improvements in urinary tract infections (UTI) and hospital-acquired pneumonia (HAP). In the post-intervention phase 100% of UTI were treated as recommended, compared to 30% before the intervention (P UTI. Before implementation of the clinical guidelines, HAP was inappropriately treated like community-acquired pneumonia (CAP). Immediately after the intervention, 50% of HAP patients were treated as recommended, and 1 year later (follow-up phase) 56% of HAP patients received the recommended antibiotic medication. This change in prescription practice was significant (P < 0.05). Antibiotic treatment guidelines for the

    Full Text Available BACKGROUND: Unnecessary or inappropriate use of antimicrobials is associated with the emergence of antimicrobial resistance, drug toxicity, increased morbidity and health care costs. Antimicrobial use has been reported to be incorrect or not indicated in 9-64% of inpatients. We studied the quality of antimicrobial therapy and prophylaxis in hospitalized patients at a tertiary care hospital to plan interventions to improve the quality of antimicrobial prescription. METHODOLOGY/PRINCIPAL FINDINGS: Experienced infectious diseases (ID fellows performed audits of antimicrobial use at regular intervals among all patients--with or without antimicrobials--hospitalized in predefined surgical, medical, haemato-oncological, or intensive care units. Data were collected from medical and nursing patient charts with a standardized questionnaire. Appropriateness of antimicrobial use was evaluated using a modified algorithm developed by Gyssens et al.; the assessment was double-checked by a senior ID specialist. We evaluated 1577 patients of whom 700 (44.4% had antimicrobials, receiving a total of 1270 prescriptions. 958 (75.4% prescriptions were for therapy and 312 (24.6% for prophylaxis. 37.0% of therapeutic and 16.6% of prophylactic prescriptions were found to be inappropriate. Most frequent characteristics of inappropriate treatments included: No indication (17.5%; incorrect choice of antimicrobials (7.6%; incorrect application of drugs (9.3%; and divergence from institutional guidelines (8%. Characteristics of inappropriate prophylaxes were: No indication (9%; incorrect choice of antimicrobials (1%; duration too long or other inappropriate use (6.7%. Patterns of inappropriate antimicrobial varied widely in the different hospital units; empirical prescriptions were more frequently incorrect than prescriptions based on available microbiological results. CONCLUSIONS/SIGNIFICANCE: Audits of individual patient care provide important data to identify local

    Due to the high rates of inappropriate antibiotic prescribing for presumed urinary tract infections (UTIs) in nursing home (NH) residents, we sought to examine the antibiotic prescribing pathway and the extent to which it agrees with the Loeb criteria; findings can suggest strategies for antibiotic stewardship. Chart review of 260 randomly-selected cases from 247 NH residents treated with an antibiotic for a presumed UTI in 31 NHs in North Carolina. We examined the prescribing pathway from presenting illness, to the prescribing event, illness work-up and subsequent clinical events including emergency department use, hospitalization, and death. Analyses described the decision-making processes and outcomes and compared decisions made with Loeb criteria for initiation of antibiotics. Of 260 cases, 60% had documented signs/symptoms of the presenting illness and 15% met the Loeb criteria. Acute mental status change was the most commonly documented sign/symptom (24%). NH providers (81%) were the most common prescribers and ciprofloxacin (32%) was the most commonly prescribed antibiotic. Fourteen percent of presumed UTI cases included a white blood cell count, 71% included a urinalysis, and 72% had a urine culture. Seventy-five percent of cultures grew at least one organism with ≥100,000 colony-forming units/milliliter and 12% grew multi-drug resistant organisms; 28% of antibiotics were prescribed for more than 7 days, and 7% of cases had a subsequent death, emergency department visit, or hospitalization within 7 days. Non-specific signs/symptoms appeared to influence prescribing more often than urinary tract-specific signs/symptoms. Prescribers rarely stopped antibiotics, and a minority prescribed for overly long periods. Providers may need additional support to guide the decision-making process to reduce antibiotic overuse and antibiotic resistance. © 2017, Copyright the Authors Journal compilation © 2017, The American Geriatrics Society.

    Background The aim of the present study was to determine predictors of inappropriate use of diagnostic tests and management of bronchiolitis in a population of hospitalized infants. Methods In an analytical cross-sectional study, we determined independent predictors of the inappropriate use of diagnostic tests and management of bronchiolitis in a population of hospitalized infants. We defined a composite outcome score as the main outcome variable. Results Of the 303 included patients, 216 (71.3%) experienced an inappropriate use of diagnostic tests and treatment of bronchiolitis. After controlling for potential confounders, it was found that atopic dermatitis (OR 5.30; CI 95% 1.14–24.79; p = 0.034), length of hospital stay (OR 1.48; CI 95% 1.08–2.03; p = 0.015), and the number of siblings (OR 1.92; CI 95% 1.13–3.26; p = 0.015) were independent predictors of an inappropriate use of diagnostic tests and treatment of the disease. Conclusions Inappropriate use of diagnostic tests and treatment of bronchiolitis was a highly prevalent outcome in our population of study. Participants with atopic dermatitis, a longer hospital stay, and a greater number of siblings were at increased risk for inappropriate use of diagnostic tests and management of the disease.

    Full Text Available Aim: Although prophylactic antibiotic treatment is still debatable, it is currently in use in recurrent urinary tract infections (UTIs. In the present study, we aimed to observe if prophylactic antibiotic use had any effect on the development of antibiotic resistance in patients with recurrent UTIs who we followed up in our clinic. Methods: The present study was performed on patients aged between one month and 16 years, who had recurrent UTIs, and were followed up by the Department of Pediatrics at Bülent Ecevit University Medical School. Patient files were retrospectively reviewed, and 50 patients who received antibiotic prophylaxis and 100 patients without prophylaxis were enrolled in the study. Urinary tests, subsequent urinary culture results, and antibiotic resistances were compared between the groups. Results: The mean age was 42.7±44.2 months. The most frequently cultured isolated bacterium was Escherichia coli (E. coli (58.4%. No difference was determined in bacteria in cultures between prophylaxis receivers and non-receivers. Isolation rate of E. coli was higher in urinary cultures in females than in males (p<0.001. When antibiotic resistance of all urinary culture-isolated bacteria was compared between the two groups, there was no statistically significant difference. However, an increased resistance against amoxicillin/clavulanic acid, ceftriaxone, and piperacillin was determined in prophylaxis group in whom E. coli was grown. In this study, general antibiotic resistance was most frequently observed against ampicillin (71.9%. Conclusion: In the present study, we observed that prophylaxis did not contribute so much to resistance other than E. coli. We recommend not preferring antibiotics which have increased resistance in our institution especially in children receiving prophylaxis for empirical treatment.

    Urinary tract infections (UTI) are a very common reason for consultation and prescription in current practice. Excessive or inappropriate use of antibiotics in treating urinary tract infections is responsible for the emergence and spread of multiresistant uropathogenic bacteria. To evaluate the isolation frequency and antibiotic resistance of uropathogenic Escherichia coli strains isolated at the Marrakech region. We conducted a retrospective study over a period of three years (from 1st January 2010 to 31 December 2012). It included all non-redundant uropathogenic E. coli strains isolated in the microbiology laboratory of the Avicenne hospital of Marrakech, Morocco. During this study, 1472 uropathogenic enterobacteriaceae were isolated including 924 non-repetitive E. coli strains, an overall isolation frequency of 63%. Antibiotic resistance of isolated E. coli strains showed resistance rates to amoxicillin (65%), sulfamethoxazole-triméthropime (55%), amoxicillin-clavulanic acid (43%), ciprofloxacin (22%), gentamicin (14%), nitrofurans (11%), amikacin (8%) and fosfomycin (7%). The number of E. coli strains resistant to C3G by ESBL production was 67, an average frequency of 4.5% of all isolated uropathogenic enterobacteria. The associated antibiotic resistance in the case of ESBL-producing E. coli were 82% for ciprofloxacin, 76% for sulfamethozole trimethoprim, 66% for gentamicin and 56% for amikacin. No resistance to imipenem was recorded for the isolated E. coli strains, which represents an imipenem sensitivity of 100%. Antibiotic resistance of uropathogenic E. coli strains limits treatment options and therefore constitutes a real public health problem. The regular updating of antibiotic susceptibility statistics of E. coli strains allows a better adaptation of the probabilistic antibiotic therapy to local epidemiological data.

    Adequate management of severely ill patients with secondary peritonitis requires supportive therapy of organ dysfunction, source control of infection and antimicrobial therapy. Since secondary peritonitis is polymicrobial, appropriate empiric therapy requires combination therapy in order to achieve the needed coverage for both common and more unusual organisms. This article reviews etiological agents, resistance mechanisms and their prevalence, how and when to cover them and guidelines for treatment in the literature. Local surveillances are the basis for the selection of compounds in antibiotic regimens, which should be further adapted to the increasing number of patients with risk factors for resistance (clinical setting, comorbidities, previous antibiotic treatments, previous colonization, severity…). Inadequate antimicrobial regimens are strongly associated with unfavorable outcomes. Awareness of resistance epidemiology and of clinical consequences of inadequate therapy against resistant bacteria is crucial for clinicians treating secondary peritonitis, with delicate balance between optimization of empirical therapy (improving outcomes) and antimicrobial overuse (increasing resistance emergence).

    Background Inappropriate antimicrobial use has been shown to be an important determinant of the emergence of antimicrobial resistance (AMR). Health information technology (HIT) in the form of Computerised Decision Support (CDS) represents an option for improving antimicrobial prescribing and containing AMR. Objectives To evaluate the evidence for CDS in improving quantitative and qualitative measures of antibiotic prescribing in inpatient hospital settings. Methods A systematic literature search was conducted of articles published from inception to 20th December 2014 using eight electronic databases: MEDLINE, EMBASE, PUBMED, Web of Science, CINAHL, Cochrane Library, HMIC and PsychINFo. An updated systematic literature search was conducted from January 1st 2015 to October 1st 2016 using PUBMED. The search strategy used combinations of the following terms: (electronic prescribing) OR (clinical decision support) AND (antibiotic or antibacterial or antimicrobial) AND (hospital or secondary care or inpatient). Studies were evaluated for quality using a 10-point rating scale. Results Eighty-one studies were identified matching the inclusion criteria. Seven outcome measures were evaluated: adequacy of antibiotic coverage, mortality, volume of antibiotic usage, length of stay, antibiotic cost, compliance with guidelines, antimicrobial resistance, and CDS implementation and uptake. Meta-analysis of pooled outcomes showed CDS significantly improved the adequacy of antibiotic coverage (n = 13; odds ratio [OR], 2.11 [95% CI, 1.67 to 2.66, p ≤ 0.00001]). Also, CDS was associated with marginally lowered mortality (n = 20; OR, 0.85 [CI, 0.75 to 0.96, p = 0.01]). CDS was associated with lower antibiotic utilisation, increased compliance with antibiotic guidelines and reductions in antimicrobial resistance. Conflicting effects of CDS on length of stay, antibiotic costs and system uptake were also noted. Conclusions CDS has the potential to improve the adequacy of antibiotic

    Full Text Available BACKGROUND: Inappropriate prescription of antibiotics may contribute towards higher levels antimicrobial resistance. A key intervention for improving appropriate antibiotic prescription is surveillance of prescription. This paper presents the results of a longitudinal surveillance of broad-spectrum antibiotic prescription in 5 public-sector hospitals in Singapore from 2006 to 2010. METHODOLOGY/PRINCIPAL FINDINGS: Quarterly antibiotic prescription data were obtained and converted to defined daily doses (DDDs per 1,000 inpatient-days. The presence of significant trends in antibiotic prescription over time for both individual and combined hospitals was tested by regression analysis and corrected for autocorrelation between time-points. Excluding fluoroquinolones, there was a significant increase in prescription of all monitored antibiotics from an average of 233.12 defined daily doses (DDD/1,000 inpatient-days in 2006 to 254.38 DDD/1,000 inpatient-days in 2010 (Coefficient = 1.13, 95%CI: 0.16-2.09, p = 0.025. Increasing utilization of carbapenems, piperacillin/tazobactam, and Gram-positive agents were seen in the majority of the hospitals, while cephalosporins were less prescribed over time. The combined expenditure for 5 hospitals increased from USD9.9 million in 2006 to USD16.7 million in 2010. CONCLUSIONS/SIGNIFICANCE: The rate of prescription of broad-spectrum antibiotics in Singaporean hospitals is much higher compared to those of European hospitals. This may be due to high rates of antimicrobial resistance. The increase in expenditure on monitored antibiotics over the past 5 years outstripped the actual increase in DDD/1,000 inpatient-days of antibiotics prescribed. Longitudinal surveillance of antibiotic prescription on a hospital and countrywide level is important for detecting trends for formulating interventions or policies. Further research is needed to understand the causes for the various prescription trends and to act on these where

    Objectives. To identify 1 the characteristics of patients receiving non acute (inappropriate care and 2 the variables associated to inappropriate hospital use, in order to 3 estimate the relevance of the problem and to 4 focus future concurrent reviews and efforts to allocate patients to alternative health care settings.

    Design. A prospective review of a random sample of adult patients who presented to the Emergency Department of the Molinette Hospital. Patients were assessed at admission and on day 3, 5and 8 using the Appropriateness Evaluation Protocol (Italian validated version. Patients: 490 overall; 312 (64 % medical and 178 (36 % surgical.

    Outcome measures. Acute (appropriate and non acute (inappropriate admissions, Major Disease Category, costs, mean weights of Diagnosis Related Groups, and length of stay (days.

    Results. The proportion of patients requiring acute care declined rapidly from presentation (84.5% to the fifth day of admission (60.9%. Patients admitted during weekends showed a higher rate of inappropriate stay on day 5 (P=0.04. The proportion of inappropriate admissions was higher for medical rather than surgical patients (P=0.07 at presentation and at day 5 (P < 0.01. Traditional social-demographic variables were not significant risk indicators for inappropriate admissions. The likelihood ratio for inappropriate admission at presentation was significantly higher for minor illnesses and disturbances (P=0.03.

    Inappropriate stay on day 5 was significantly associated with lower cost (P < 0.01, lower mean DRG weight (P < 0.01 and shorter length of stay (P=0.05 for medical but not for surgical admissions.

    Community-acquired pneumonia (CAP) encompasses a broad spectrum of disease severity and may require outpatient, inpatient, or intensive care management. Successful treatment hinges on expedient delivery of appropriate antibiotic therapy tailored to both the likely offending pathogens and the severity of disease. This review summarizes key principles in starting treatment and provides recommended empiric therapy regimens for each site of care. In addition, we discuss the antimicrobial and anti-inflammatory role macrolides play in CAP, as well as specific information for managing individual CAP pathogens such as community-acquired methicillin-resistant Staphylococcus aureus and drug-resistant Streptococcus pneumoniae . We also examine several novel antibiotics being developed for CAP and review the evidence guiding duration of therapy and current best practices for the transition of hospitalized patients from intravenous antibiotics to oral therapy.

    There is significant diversity in the utilization of antibiotics for neonates undergoing surgical procedures. Our institution standardized antibiotic administration for surgical neonates, in which no empiric antibiotics were given to infants with surgical conditions postnatally, and antibiotics are given no more than 72 hours perioperatively. We compared the time periods before and after implementation of antibiotic protocol in an institution review board-approved, retrospective review of neonates with congenital surgical conditions who underwent surgical correction within 30 days after birth. Surgical site infection at 30 days was the primary outcome, and development of hospital-acquired infections or multidrug-resistant organism were secondary outcomes. One hundred forty-eight infants underwent surgical procedures pre-protocol, and 127 underwent procedures post-protocol implementation. Surgical site infection rates were similar pre- and post-protocol, 14% and 9% respectively, (P = .21.) The incidence of hospital-acquired infections (13.7% vs 8.7%, P = .205) and multidrug-resistant organism (4.7% vs 1.6%, P = .143) was similar between the 2 periods. Elimination of empiric postnatal antibiotics did not statistically change rates of surgical site infection, hospital-acquired infections, or multidrug-resistant organisms. Limiting the duration of perioperative antibiotic prophylaxis to no more than 72 hours after surgery did not increase the rate of surgical site infection, hospital-acquired infections, or multidrug-resistant organism. Median antibiotic days were decreased with antibiotic standardization for surgical neonates. Copyright © 2017 Elsevier Inc. All rights reserved.

    Full Text Available AIMS: Radiological inappropriateness in medical imaging leads to loss of resources and accumulation of avoidable population cancer risk. Aim of the study was to audit the appropriateness rate of different cardiac radiological examinations. METHODS AND PRINCIPAL FINDINGS: With a retrospective, observational study we reviewed clinical records of 818 consecutive patients (67 ± 12 years, 75% males admitted from January 1-May 31, 2010 to the National Research Council - Tuscany Region Gabriele Monasterio Foundation cardiology division. A total of 940 procedures were audited: 250 chest x-rays (CXR; 240 coronary computed tomographies (CCT; 250 coronary angiographies (CA; 200 percutaneous coronary interventions (PCI. For each test, indications were rated on the basis of guidelines class of recommendation and level of evidence: definitely appropriate (A, including class I, appropriate, and class IIa, probably appropriate, uncertain (U, class IIb, probably inappropriate, or inappropriate (I, class III, definitely inappropriate. Appropriateness was suboptimal for all tests: CXR (A = 48%, U = 10%, I = 42%; CCT (A = 58%, U = 24%, I = 18%; CA (A = 45%, U = 25%, I = 30%; PCI (A = 63%, U = 15%, I = 22%. Top reasons for inappropriateness were: routine on hospital admission (70% of inappropriate CXR; first line application in asymptomatic low-risk patients (42% of CCT or in patients with unchanged clinical status post-revascularization (20% of CA; PCI in patients either asymptomatic or with miscellaneous symptoms and without inducible ischemia on non-invasive testing (36% of inappropriate PCI. CONCLUSION AND SIGNIFICANCE: Public healthcare system--with universal access paid for with public money--is haemorrhaging significant resources and accumulating avoidable long-term cancer risk with inappropriate cardiovascular imaging prevention.

    Antimicrobial stewardship to combat the spread of antibiotic-resistant bacteria has become a national priority. This project focuses on reducing inappropriate use of antimicrobials for asymptomatic bacteriuria (ASB), a very common condition that leads to antimicrobial overuse in acute and long-term care. We previously conducted a successful intervention, entitled "Kicking Catheter Associated Urinary Tract Infection (CAUTI): the No Knee-Jerk Antibiotics Campaign," to decrease guideline-discordant ordering of urine cultures and antibiotics for ASB. The current objective is to facilitate implementation of a scalable version of the Kicking CAUTI campaign across four geographically diverse Veterans Health Administration facilities while assessing what aspects of an antimicrobial stewardship intervention are essential to success and sustainability. This project uses an interrupted time series design with four control sites. The two main intervention tools are (1) an evidence-based algorithm that distills the guidelines into a streamlined clinical pathway and (2) case-based audit and feedback to train clinicians to use the algorithm. Our conceptual framework for the development and implementation of this intervention draws on May's General Theory of Implementation. The intervention is directed at providers in acute and long-term care, and the goal is to reduce inappropriate screening for and treatment of ASB in all patients and residents, not just those with urinary catheters. The start-up for each facility consists of centrally-led phone calls with local site champions and baseline surveys. Case-based audit and feedback will begin at a given site after the start-up period and continue for 12 months, followed by a sustainability assessment. In addition to the clinical outcomes, we will explore the relationship between the dose of the intervention and clinical outcomes. This project moves from a proof-of-concept effectiveness study to implementation involving

    New antibiotic agents and changing susceptibility patterns may have changed the empirical treatment of bacterial keratitis. Our objective in this study was to survey cornea specialists' practice patterns in the initial treatment of bacterial ulcers. This study consisted of a short online survey emailed to members of the Cornea Society listserv for an international sample of cornea specialists. Data collection began July 2014 and ended October 2014. A total of 1009 surveys were emailed, and we received 140 (14%) responses. The majority of US clinicians surveyed (n=83, 80%) chose fortified antibiotics empirically, with 55% (n=57) selecting fortified vancomycin and 16% (n=17) using fluoroquinolone alone. International respondents were twice as likely to use fluoroquinolone monotherapy (31%, n=11, p=0.07) and less likely to use fortified vancomycin (33%, n=12, p=0.03). Forty-five per cent (n=46) of US respondents reported that their initial antibiotic choice covered methicillin-resistant Staphylococcus aureus , compared with 22% (n=8) of international respondents (p<0.01). Overall, respondents who were concerned about availability of antibiotics and toxicity were 20.86 (p<0.001) and 7.48 (p<0.001) times more likely to choose fluoroquinolone monotherapy, respectively. If respondents' primary considerations were broad spectrum coverage or antibiotic resistance they had 7.10 (p<0.001) and 12.51 (p<0.001) times the odds of using fortified vancomycin, respectively. Practice patterns for the initial treatment of bacterial keratitis vary with clinicians in the USA being more likely to use fortified antibiotics versus fluoroquinolone monotherapy and more concerned with resistant organisms than their international peers.

    Urinary tract infections (UTIs) occur in about 8% of pregnant women, and untreated UTIs can have serious consequences, including pyelonephritis, preterm labor, low birth weight, and sepsis (1). Pregnant women are typically screened for UTIs during early pregnancy, and those with bacteriuria are treated with antibiotics (1,2). Antibiotic stewardship is critical to improving patient safety and to combating antibiotic resistance. Because of the potential risk for birth defects, including anencephaly, heart defects, and orofacial clefts, associated with use of sulfonamides and nitrofurantoin during pregnancy (3), a 2011 committee opinion from the American College of Obstetricians and Gynecologists (ACOG) recommended that sulfonamides and nitrofurantoin may be prescribed in the first trimester of pregnancy only when other antimicrobial therapies are deemed clinically inappropriate (4). To assess the effects of these recommendations, CDC analyzed the Truven Health MarketScan Commercial Database* to examine antibiotic prescriptions filled by pregnant women with UTIs. Among 482,917 pregnancies in 2014, 7.2% of women had an outpatient UTI diagnosis during the 90 days before the date of last menstrual period (LMP) or during pregnancy. Among pregnant women with UTIs, the most frequently prescribed antibiotics during the first trimester were nitrofurantoin, ciprofloxacin, cephalexin, and trimethoprim-sulfamethoxazole. Given the potential risks associated with use of some of these antibiotics in early pregnancy and the potential for unrecognized pregnancy, women's health care providers should be familiar with the ACOG recommendations and consider the possibility of early pregnancy when treating women of reproductive age.

    Our objective was to identify clinical predictors of antibiotic treatment effects in hospitalized patients with community-acquired pneumonia (CAP) who were not in the intensive care unit (ICU). Post-hoc analysis of three prospective cohorts (from the Netherlands and Spain) of adult patients with CAP admitted to a non-ICU ward having received either β-lactam monotherapy, β-lactam + macrolide, or a fluoroquinolone-based therapy as empirical antibiotic treatment. We evaluated candidate clinical predictors of treatment effects in multiple mixed-effects models by including interactions of the predictors with empirical antibiotic choice and using 30-day mortality, ICU admission and length of hospital stay as outcomes. Among 8562 patients, empirical treatment was β-lactam in 4399 (51.4%), fluoroquinolone in 3373 (39.4%), and β-lactam + macrolide in 790 (9.2%). Older age (interaction OR 1.67, 95% CI 1.23-2.29, p 0.034) and current smoking (interaction OR 2.36, 95% CI 1.34-4.17, p 0.046) were associated with lower effectiveness of fluoroquinolone on 30-day mortality. Older age was also associated with lower effectiveness of β-lactam + macrolide on length of hospital stay (interaction effect ratio 1.14, 95% CI 1.06-1.22, p 0.008). Older age and smoking could influence the response to specific antibiotic regimens. The effect modification of age and smoking should be considered hypothesis generating to be evaluated in future trials.

    Peri-implantitis has emerged in the last few years as a complication difficult to resolve. The etiopathogenesis consensus is mainly attributed to bacteria. Following the preferred reporting items for systematic reviews and meta-analysis (PRISMA) guidelines, a PubMed/Medline literature search was performed using the US National Library of Medicine database up to 2015 to analyze available scientific data on the rationale and risk of superinfection associated to systemic antimicrobials in human peri-implant disease. A hand search was also conducted on relevant medical and microbiology journals. The methodological index for non-randomized studies (MINORS) was independently assessed for quality on the selected papers. Proposed combined therapies use broad-spectrum antibiotics to halt the disease progression. A major associated risk, particularly when prescribed empirically without microbiological follow-up, is the undetected development of superinfections and overgrowth of opportunistic pathogens difficult to eradicate. Peri-implant superinfections with opportunistic bacteria, yeast and viruses, are plausible risks associated to the use of systemic antibiotics in immunocompetent individuals. Lack of microbiological follow-up and antibiotic susceptibility testing may lead to ongoing microbial challenges that exacerbate the disease progression. The increased proliferation of antimicrobial resistance, modern implant surface topography and indiscriminative empiric antibiotic regimens may promote the escalation of peri-implant disease in years to come. A personalized 3-month supportive therapy may help prevent risks by sustaining a normal ecological balance, decreasing specific pathogen proportions and maintaining ideal plaque control.

    2016-01-01

    Full Text Available Introduction: Antibiotics are the most frequently used drugs in hospitalized patients, but studies have shown that the prescribed antibiotics may be inappropriate and may contribute to bacterial resistance. The aim of this work is the evaluation of antibiotic consumption in Clinical Centre Nis, Serbia from 2011 to 2014, with the focus on the monitoring of the ceftriaxone (CTX and ciprofloxacin (CIP utilization. Secondly, we screened bacterial resistance towards monitored antibiotics used for intra-abdominal infection (IAI and urinary tract infection (UTI in tertiary healthcare institution. Methods: Antibiotics consumption and antimicrobial resistance were monitored in the tertiary care university hospital-Clinical Centre Nis from 2011 to 2014. Data on the use of antibiotics in inpatients were obtained and expressed as defined daily doses per 100 bed days (DBD. Bacterial resistances were given as percentages of resistant isolates. Results: During the investigation period the use of cephalosporins increased by 6.39 %, from 2011 to 2013, but in 2014 there was a reduction in its consumption by 16.46 %. Penicillins consumption had a decreasing trend, whereas quinolones consumption was variable during observation period. The resistance of K. pneumoniae to CTX and CIP for the isolates from IAI, and resistance of E. coli to analyze antibiotics for isolates from UTI showed increasing trend within observed period of time. Conclusions: Our findings shows that cephalosporins were the most frequently used antibiotics in Clinical Centre Nis, and they were followed by penicillins and quinolones. Additionally, K. pneumoniae resistance to CTX and CIP increased markedly in IAI, while E. coli resistance showed an increasing trend to CTX and CIP in UTI over the study period.

    Full Text Available Abstract Background The prevalence and risk factors of potentially inappropriate medication use among the elderly patients have been studied in various countries, but because of the difficulty of obtaining data on patient characteristics and medications they have not been studied in Japan. Methods We conducted a retrospective cross-sectional study in 17 Japanese long-term care (LTC facilities by collecting data from the comprehensive MDS assessment forms for 1669 patients aged 65 years and over who were assessed between January and July of 2002. Potentially inappropriate medications were identified on the basis of the 2003 Beers criteria. Results The patients in the sample were similar in terms of demographic characteristics to those in the national survey. Our study revealed that 356 (21.1% of the patients were treated with potentially inappropriate medication independent of disease or condition. The most commonly inappropriately prescribed medication was ticlopidine, which had been prescribed for 107 patients (6.3%. There were 300 (18.0% patients treated with at least 1 inappropriate medication dependent on the disease or condition. The highest prevalence of inappropriate medication use dependent on the disease or condition was found in patients with chronic constipation. Multiple logistic regression analysis revealed psychotropic drug use (OR = 1.511, medication cost of per day (OR = 1.173, number of medications (OR = 1.140, and age (OR = 0.981 as factors related to inappropriate medication use independent of disease or condition. Neither patient characteristics nor facility characteristics emerged as predictors of inappropriate prescription. Conclusion The prevalence and predictors of inappropriate medication use in Japanese LTC facilities were similar to those in other countries.

    Older patients receiving home health care are particularly at risk of receiving potentially inappropriate medications compared to community-dwelling population. Data on appropriateness of prescribing in these patients is limited. To investigate the prevalence, patterns and determinants of potentially inappropriate medications among elderly patients receiving Home Health Care Services in Qatar. Home Health Care Services department in Hamad Medical Corporation-Qatar. A cross-sectional study, conducted over a 3 months period. Patients 65 years and older, taking at least one medication and receiving home care services were included. Potentially inappropriate medications were identified and classified in accordance with the American Geriatrics Society 2012 Beers Criteria. Prevalence of potentially inappropriate medications using updated Beers criteria. A total of 191 patients (38.2%) had at least one potentially inappropriate medication. As per Beers criteria, 35% of medications were classified as medications to be avoided in older adults regardless of conditions and 9% as potentially inappropriate medications when used with certain diseases or syndromes. The majority of potentially inappropriate medications (56%) were classified as medications to be used with caution. The two leading classes of potentially inappropriate medications were antipsychotics (27.4%) and selective serotonin reuptake inhibitors (16%). Significant predictors of inappropriate prescribing were hypertension [adjusted OR 1.7; 95% CI (1.0, 2.8)], dementia [adjusted OR 2.0; 95% CI (1.2, 3.1)], depression [adjusted OR 21.6; 95% CI (2.8, 168.4)], and taking more than ten prescribed medications [adjusted OR 1.9; 95% CI (1.3, 2.8)]. Prescribing potentially inappropriate medications is common among older adults receiving home health care services in Qatar, a finding that warrants further attention. Polypharmacy, hypertension, depression and dementia were significantly associated with potentially

    Full Text Available Abstract Background The objective of this study is to analyze the factors that are associated with the adequacy of empirical antibiotic therapy and its impact in mortality in a large cohort of patients with extended-spectrum β-lactamase (ESBL - producing Escherichia coli and Klebsiella spp. bacteremia. Methods Cases of ESBL producing Enterobacteriaceae (ESBL-E bacteremia collected from 2003 through 2008 in 19 hospitals in Spain. Statistical analysis was performed using multivariate logistic regression. Results We analyzed 387 cases ESBL-E bloodstream infections. The main sources of bacteremia were urinary tract (55.3%, biliary tract (12.7%, intra-abdominal (8.8% and unknown origin (9.6%. Among all the 387 episodes, E. coli was isolated from blood cultures in 343 and in 45.71% the ESBL-E was multidrug resistant. Empirical antibiotic treatment was adequate in 48.8% of the cases and the in hospital mortality was 20.9%. In a multivariate analysis adequacy was a risk factor for death [adjusted OR (95% CI: 0.39 (0.31-0.97; P = 0.04], but not in patients without severe sepsis or shock. The class of antibiotic used empirically was not associated with prognosis in adequately treated patients. Conclusion ESBL-E bacteremia has a relatively high mortality that is partly related with a low adequacy of empirical antibiotic treatment. In selected subgroups the relevance of the adequacy of empirical therapy is limited.

    2008-01-01

    Full Text Available Abstract Background Any intervention to reduce the inappropriate use of antibiotics for infections in children has the potential to reduce the selective pressure on antimicrobial resistance and minimise the medicalisation of self-limiting illness. Little is known about whether homeopathic products might be used by some families as an alternative to antibiotics or the characteristics of such families. We used the Avon Longitudinal Study of Parents and Children (ALSPAC observational dataset to explore the hypothesis that the use of homeopathic products is associated with reduced antibiotic use in pre-school children and to identify characteristics of the families of pre-school children given homeopathic products. Methods Questionnaires data were completed by the parents of 9723 children while aged between 3–4.5 years in Bristol UK. Univariable and multivariable analyses were used to explore the relationships between antibiotic and homeopathic product use. Results Six percent of children had received one or more homeopathic products and 62% one or more antibiotics between the ages of 3 and 4.5 years. After adjustment for factors associated with antibiotic use, there was no association between homeopathic product and antibiotic use (adjusted OR = 1.02, 95% CI 0.84, 1.24. Factors independently associated with child homeopathic product use were: higher maternal education, maternal use of homeopathic products, maternal lack of confidence in doctors, mothers reporting that they were less likely to see doctor when the child was ill, children being given vitamins, watching less television and suffering from wheeze and food allergies. Conclusion In this observational study, the use of homeopathic products was not associated with decreased antibiotic consumption, suggesting the use of homeopathic product complements rather than competes with the use of antibiotics in pre-school children. The characteristics of mothers giving homeopathic products to their

    2006-06-01

    Full Text Available Abstract Background More than half of all antibiotic prescriptions in general practice are issued for respiratory tract infections (RTIs, despite convincing evidence that many of these infections are caused by viruses. Frequent misuse of antimicrobial agents is of great global health concern, as we face an emerging worldwide threat of bacterial antibiotic resistance. There is an increasing need to identify determinants and patterns of antibiotic prescribing, in order to identify where clinical practice can be improved. Methods/Design Approximately 80 peer continuing medical education (CME groups in southern Norway will be recruited to a cluster randomized trial. Participating groups will be randomized either to an intervention- or a control group. A multifaceted intervention has been tailored, where key components are educational outreach visits to the CME-groups, work-shops, audit and feedback. Prescription Peer Academic Detailers (Rx-PADs, who are trained GPs, will conduct the educational outreach visits. During these visits, evidence-based recommendations of antibiotic prescriptions for RTIs will be presented and software will be handed out for installation in participants PCs, enabling collection of prescription data. These data will subsequently be linked to corresponding data from the Norwegian Prescription Database (NorPD. Individual feedback reports will be sent all participating GPs during and one year after the intervention. Main outcomes are baseline proportion of inappropriate antibiotic prescriptions for RTIs and change in prescription patterns compared to baseline one year after the initiation of the tailored pedagogic intervention. Discussion Improvement of prescription patterns in medical practice is a challenging task. A thorough evaluation of guidelines for antibiotic treatment in RTIs may impose important benefits, whereas inappropriate prescribing entails substantial costs, as well as undesirable consequences like development

    Worldwide data indicate that antibiotics are frequently used inappropriately. The objective of this study was to investigate the extent of storage and wastage of antibacterial agents in households in Novi Sad, Serbia. The study was performed in 8 months period (December 2011-July 2012) in households in Novi Sad, Serbia. The households were randomly selected from the telephone directory. The interviewer performed the survey visiting each household. The total number of antibacterial agents in the 383 surveyed households was 318, constituting 7.3% of the total stored medications. From 383 families included in the study antibiotics were found in 178 (46.5%). In 13 (7.3%) families were found more than one pack of the same antibiotics. The median number of antibacterial agents per household was 1 (range 1-5). The most common antibacterial agents that were not in current use were cephalexin (22.1%) and amoxicillin (16.6%), followed by doxycycline (11.4%), sulfamethoxazole/trimethoprim (11.4%) and amoxicillin/clavulanic acid (9.2%). The percentage of expired antibacterial agents was 20.8%, while 85.2% were not currently in use. Antibacterial agents were commonly encountered in Serbian households, and a relatively large percentage was wasted. Informational and educational activities aimed at improving the public knowledge about antimicrobials play the leading role in reducing imprudent use of antibiotics.

    The inappropriate use of antibiotics leads to antibiotic resistance, which is a major health care problem. The current method for determination of bacterial susceptibility to antibiotics requires overnight cultures. However most of the infections cannot wait for the results to receive treatment, so physicians administer general spectrum antibiotics. This results in ineffective treatments and aggravates the rising problem of antibiotic resistance. In this work, a rapid method for diagnosis and antibiogram for a bacterial infection was developed using Surface Enhanced Raman Spectroscopy (SERS) with silver nanoparticles. The advantages of this novel method include its rapidness and efficiency which will potentially allow doctors to prescribe the most appropriate antibiotic for an infection. SERS spectra of three species of gram negative bacteria, Escherichia coli, Proteus spp., and Klebsiella spp. were obtained after 0 and 4 hour exposure to the seven different antibiotics. Bacterial strains were diluted in order to reach the concentration of (2x105 cfu/ml), cells/ml which is equivalent to the minimum concentration found in urine samples from UTIs. Even though the concentration of bacteria was low, species classification was achieved with 94% accuracy using spectra obtained at 0 hours. Sensitivity or resistance to antibiotics was predicted with 81%-100% accuracy from spectra obtained after 4 hours of exposure to the different antibiotics. This technique can be applied directly to urine samples, and with the enhancement provided by SERS, this method has the potential to be developed into a rapid method for same day UTI diagnosis and antibiogram.

    Respiratory infections account for significant morbidity, mortality and expenses to patients getting admitted to ICU. Antibiotic resistance is a major worldwide concern in ICU, including India. It is important to know the antibiotic prescribing pattern in ICU, organisms and its resistance pattern as there is sparse data on Indian ICUs. We conducted a prospective study from August 2015 to February 2016. All patients getting admitted to RICU with respiratory infection who were treated with antibiotics were included into study. Demographic details, comorbidities, Clinco-pathological score (CPI) on day1 and 2 of admission, duration of ICU admission, number of antibiotics used, antibiotic prescription, antimicrobial resistance pattern of patients were collected using APRISE questionnaire. During study period 352 patients were screened and 303 patients were included into study. Mean age was 56.05±16.37 and 190 (62.70%) were men. Most common diagnosis was Pneumonia (66%). Piperacillin-tazobactam was most common empirical antibiotic used. We found 60% resistance to piperacillin-tazobactam. Acinetobacter baumanii was the most common organism isolated (29.2%) and was highly resistant to Carbapenem (60%). Klebsiella pneumoniae was resistant to Amikacin (45%), piperacillin (55%) and Ceftazidime (50%). Piperacillin-tazobactam was the most common antibiotic prescribed to patients with respiratory infection admitted to ICU. More than half of patients (60%) had resistance to the empirical antibiotic used in our ICU, highlighting the need for antibiogram for each ICU. Thirty six percent of patient had prior antibiotic use and had mainly gram negative organisms with high resistance to commonly used antibiotics.

    Antibiotics are heavily used in Chinese mariculture, but only a small portion of the added antibiotics are absorbed by living creatures. Biofilm processes are universally used in mariculture wastewater treatment. In this study, removal of antibiotics (norfloxacin, rifampicin, and oxytetracycline) from wastewater by moving bed biofilm reactors (MBBRs) and the influence of antibiotics on reactor biofilm were investigated. The results demonstrated that there was no significant effect of sub-μg/L–sub-mg/L concentrations of antibiotics on TOC removal. Moreover, the relative abundance of antibiotic resistance genes (ARGs) and antibiotic resistance bacteria (ARB) in MBBR biofilm increased because of selective pressure of antibiotics. In addition, antibiotics decreased the diversity of the biofilm bacterial community and altered bacterial community structure. These findings provide an empirical basis for the development of appropriate practices for mariculture, and suggest that disinfection and advanced oxidation should be applied to eliminate antibiotics, ARGs, and ARB from mariculture wastewater. - Highlights: • The removal of antibiotics by Moving Bed Biofilm Reactors (MBBR) was investigated. • Biofilm process such as MBBR had little effect on the removal of the antibiotics. • The antibiotics decreased the diversity of biofilm bacterial community and altered bacterial community structure. • Biofilm processes in treating mariculture wastewater may be a reservoir of antibiotic resistance genes.

    2009-09-01

    Older people are a heterogeneous group of patients, often with multiple comorbidities for which they are prescribed a large number of drugs, leading to an increased risk of adverse drug reactions (ADR) and drug interactions. This risk is compounded by physiological age-related changes in physiology, changes in drug pharmacokinetics and pharmacodynamics, as well as by disease-related, functional and social issues. Inappropriate prescription of drugs is common in the older individuals and contributes to the increased risk of ADR. Several tools have been developed to detect potentially inappropriate prescription, the most frequently used in Spain being Beers\\' criteria. However, the value of these criteria is limited, especially as they were developed in a different healthcare system. In this article, the Spanish version of a new tool to detect potentially inappropriate prescriptions-STOPP (Screening Tool of Older Person\\'s Prescriptions) and START (Screening Tool to Alert doctors to Right i.e. appropriate, indicated Treatment) criteria-is presented. The creation, development, reliability, and use of these criteria in routine practice is described and discussed. These criteria have shown better sensitivity than Beers\\' criteria in detecting prescription problems and have the added value of being able to detect not only inappropriate prescription of some drugs, but also the omission of well indicated drugs. The STOPP\\/START criteria could become a useful screening tool to improve prescription in older people.

  3. Use of behavioral economics and social psychology to improve treatment of acute respiratory infections (BEARI): rationale and design of a cluster randomized controlled trial [1RC4AG039115-01] - study protocol and baseline practice and provider characteristics

    2013-01-01

    Background Inappropriate antibiotic prescribing for nonbacterial infections leads to increases in the costs of care, antibiotic resistance among bacteria, and adverse drug events. Acute respiratory infections (ARIs) are the most common reason for inappropriate antibiotic use. Most prior efforts to decrease inappropriate antibiotic prescribing for ARIs (e.g., educational or informational interventions) have relied on the implicit assumption that clinicians inappropriately prescribe antibiotics because they are unaware of guideline recommendations for ARIs. If lack of guideline awareness is not the reason for inappropriate prescribing, educational interventions may have limited impact on prescribing rates. Instead, interventions that apply social psychological and behavioral economic principles may be more effective in deterring inappropriate antibiotic prescribing for ARIs by well-informed clinicians. Methods/design The Application of Behavioral Economics to Improve the Treatment of Acute Respiratory Infections (BEARI) Trial is a multisite, cluster-randomized controlled trial with practice as the unit of randomization. The primary aim is to test the ability of three interventions based on behavioral economic principles to reduce the rate of inappropriate antibiotic prescribing for ARIs. We randomized practices in a 2 × 2 × 2 factorial design to receive up to three interventions for non-antibiotic-appropriate diagnoses: 1) Accountable Justifications: When prescribing an antibiotic for an ARI, clinicians are prompted to record an explicit justification that appears in the patient electronic health record; 2) Suggested Alternatives: Through computerized clinical decision support, clinicians prescribing an antibiotic for an ARI receive a list of non-antibiotic treatment choices (including prescription options) prior to completing the antibiotic prescription; and 3) Peer Comparison: Each provider’s rate of inappropriate antibiotic prescribing relative to top

    Modification of empirical antimicrobials when warranted by culture results or clinical signs is recommended to control antimicrobial overuse and resistance. We aimed to assess the frequency with which patients were started on empirical antimicrobials, characteristics of the empirical regimen and the clinical characteristics of patients at the time of starting antimicrobials, patterns of changes to empirical therapy at different timepoints, and modifiable factors associated with changes to the initial empirical regimen in the first 5 days of therapy. We did a chart review of adult inpatients receiving one or more antimicrobials in six US hospitals on 4 days during 2009 and 2010. Our primary outcome was the modification of antimicrobial regimen on or before the 5th day of empirical therapy, analysed as a three-category variable. Bivariate analyses were used to establish demographic and clinical variables associated with the outcome. Variables with p values below 0·1 were included in a multivariable generalised linear latent and mixed model with multinomial logit link to adjust for clustering within hospitals and accommodate a non-binary outcome variable. Across the six study sites, 4119 (60%) of 6812 inpatients received antimicrobials. Of 1200 randomly selected patients with active antimicrobials, 730 (61%) met inclusion criteria. At the start of therapy, 220 (30%) patients were afebrile and had normal white blood cell counts. Appropriate cultures were collected from 432 (59%) patients, and 250 (58%) were negative. By the 5th day of therapy, 12·5% of empirical antimicrobials were escalated, 21·5% were narrowed or discontinued, and 66·4% were unchanged. Narrowing or discontinuation was more likely when cultures were collected at the start of therapy (adjusted OR 1·68, 95% CI 1·05-2·70) and no infection was noted on an initial radiological study (1·76, 1·11-2·79). Escalation was associated with multiple infection sites (2·54, 1·34-4·83) and a positive

    Methicillin-resistant Staphylococcus aureus (MRSA) is the most reported pathogen in hand infections at urban medical centers throughout the country. Antibiotic sensitivity trends are not well known. The purposes of this study were to examine and determine the drug resistance trends for MRSA infections of the hand and to provide recommendations for empiric antibiotic treatment based on sensitivity profiles. A 10-year longitudinal, retrospective chart review was performed on all culture-positive hand infections encountered at a single urban medical center from 2005 to 2014. The proportions of all organisms were calculated for each year and collectively. MRSA infections were additionally subanalyzed for antibiotic sensitivity. A total of 815 culture-positive hand infections were identified. Overall, MRSA grew on culture in 46% of cases. A trend toward decreasing annual MRSA incidence was noted over the 10-year study period. There was a steady increase in polymicrobial infections during the same time. Resistance to clindamycin increased steadily during the 10-year study, starting at 4% in 2008 but growing to 31% by 2014. Similarly, levofloxacin resistance consistently increased throughout the study, reaching its peak at 56% in 2014. The annual incidence of MRSA in hand infections has declined overall but remains the most common pathogen. There has been an alternative increase in the number of polymicrobial infections. MRSA resistance to clindamycin and levofloxacin consistently increased during the study period. Empiric antibiotic therapy for hand infections should not only avoid penicillin and other beta-lactams but should also consider avoiding clindamycin and levofloxacin for empiric treatment.

    To study the prevalence and pregnancy outcomes of inappropriate gestational weight gain (GWG) among teenage pregnant women. A retrospective descriptive study was conducted on 2,165 teenage pregnant women who attended our antenatal clinic between January 2007 and August 2015. Adverse pregnancy outcomes, including maternal and neonatal outcomes of women with inappropriate GWG, including underweight and overweight, were studied and compared with those of women with appropriate GWG. Complete data of 1,943 women were obtained. Among these women, the mean age was 17.4±1.4 years and mean body mass index at first visit was 19.1±3.0 kg/m 2 . The prevalence of inappropriate GWG was 61.7%. Underweight women were more likely to experience anemia and preterm delivery, whereas overweight women required more cesarean sections because of cephalopelvic disproportion and preeclampsia, compared to women with appropriate weight gain (all P teenage pregnancies showed inappropriate GWG. GWG had a significant impact on pregnancy outcomes.

  7. Rapid optical determination of β-lactamase and antibiotic activity

    Background The absence of rapid tests evaluating antibiotic susceptibility results in the empirical prescription of antibiotics. This can lead to treatment failures due to escalating antibiotic resistance, and also furthers the emergence of drug-resistant bacteria. This study reports a rapid optical method to detect β-lactamase and thereby assess activity of β-lactam antibiotics, which could provide an approach for targeted prescription of antibiotics. The methodology is centred on a fluorescence quenching based probe (β-LEAF – β-Lactamase Enzyme Activated Fluorophore) that mimics the structure of β-lactam antibiotics. Results The β-LEAF assay was performed for rapid determination of β-lactamase production and activity of β-lactam antibiotic (cefazolin) on a panel of Staphylococcus aureus ATCC strains and clinical isolates. Four of the clinical isolates were determined to be lactamase producers, with the capacity to inactivate cefazolin, out of the twenty-five isolates tested. These results were compared against gold standard methods, nitrocefin disk test for β-lactamase detection and disk diffusion for antibiotic susceptibility, showing results to be largely consistent. Furthermore, in the sub-set of β-lactamase producers, it was demonstrated and validated that multiple antibiotics (cefazolin, cefoxitin, cefepime) could be assessed simultaneously to predict the antibiotic that would be most active for a given bacterial isolate. Conclusions The study establishes the rapid β-LEAF assay for β-lactamase detection and prediction of antibiotic activity using S. aureus clinical isolates. Although the focus in the current study is β-lactamase-based resistance, the overall approach represents a broad diagnostic platform. In the long-term, these studies form the basis for the development of assays utilizing a broader variety of targets, pathogens and drugs. PMID:24708478

    Full Text Available Objective: To establish the prevalence of potentially inappropriate medications prescribed for elderly patients, to identify the most commonly involved drugs, and to investigate whether age, sex and number of medications were related with the prescription of these drugs. Methods: Prescriptions for 1,800 elderly patients (≥ 60 years were gathered from a database. These prescriptions were written by general physicians at a tertiary level university hospital in the city of Sao Paulo, Brazil, from February to May 2008. Only one prescription per patient was considered. The prescriptions were classified according to sex and age (60-69, 70-79 and ≥ 80. The Beers criteria (2003 version were used to evaluate potentially inappropriate medications. Results: Most of the sample comprised women (66.6% with a mean age of 71.3 years. The mean prevalence of potentially inappropriate medication prescriptions was 37.6%. The 60-69 age group presented the highest prevalence (49.9%. The most frequently prescribed potentially inappropriate medications to women were carisoprodol, amitriptyline, and fluoxetine; amitriptyline, carisoprodol, fluoxetine and clonidine were prescribed more often to men. The female sex (p<0.001; OR=2.0 and number of medications prescribed (p<0.001 were associated with prescription of potentially inappropriate medications. The chance of having a prescription of these drugs was lower among patients aged over 80 years (OR=0.7. The mean number of prescribed medications for both sexes and all age groups was 7.1. The mean number of medications per patient was higher among females (p<0.001; this result was not age-dependent (p=0.285. Conclusion: The prevalence of potentially inappropriate medications was similar to previously reported values in the literature and was correlated with the female sex. The chance of having a potentially inappropriate medication prescription was lower among patients aged over 80 years. The chance of having a

    Extended-spectrum beta-lactamases are responsible for resistance of Gram-negative bacilli to several beta-lactam antibiotics, including those prescribed for treatment pneumonia. To evaluate the importance of colonization with E-GNB for the choice of empirical treatment we performed a retrospective case-control study including 156 patients, hospitalized for treatment of pneumonia from 2009 through 2013. Empirical treatment success and in-hospital survival were significantly lower in patients colonized with E-GNB compared to non-colonized (p = 0.002, p = 0.035). When comparing subgroups of colonized patients, treatment success was significantly lower in patients who were colonized with E-GNB resistant to empirical antibiotic (p = 0.010), but not in those colonized by E-GNB susceptible to empirically given antibiotic (p = 0.104). Difference in in-hospital mortality was insignificant in both subgroups (p = 0.056, p = 0.331). The results of study suggest that an anti-E-GNB active antibiotic should be used for empirical treatment of pneumonia in E-GNB colonized patients.

    The appropriate use of health care is an important issue in developed countries. The purpose of this study was to ascertain the extent of potentially inappropriate hospital admissions and their individual, clinical and hospital-related determinants. Medical records were analyzed for the year 2014 held by the Local Heath Unit n. 13 in the Veneto Region of north-east Italy (19,000 records). The outcomes calculated were: admissions for conditions amenable to day hospital care; brief medical admissions; outlier lengths of stay for elderly patients' medical admissions; and medical admissions to surgical wards. Univariate analyses and logistic regression models were used to test associations with demographic, clinical and hospital ward covariates, including organizational indicators. Inappropriate reliance on acute care beds ranged from 6% to 28%, depending on the type of quality indicator analyzed. Some individual features, and wards' specific characteristics were associated with at least one of the phenomena of inappropriate hospital resource usage. In particular, male gender, younger age and transferals seemed to affect inappropriate admissions to surgical wards. Potentially avoidable admissions featuring inpatients amenable to day hospital care were associated with subjects with fewer comorbidities and lower case-mix wards, while inappropriately short medical stays were influenced by patients' higher functional status and local residency and by lower bed occupancy rates. In conclusion, inappropriately long hospital stays for elderly cases were associated with patients with multiple pathologies in wards with a low bed-occupancy. Education level and citizenship did not seem to influence inappropriate admissions. Some individual, clinical ad structural characteristics of patients and wards emerging from administrative records could be associated with inappropriate reliance on acute hospital beds. Analyzing the indicators considered in this study could generate

    Widespread overuse and inappropriate use of antibiotics contribute to increasingly antibiotic-resistant pathogens and higher health care costs. It is not clear whether routine antibiotic prophylaxis can reduce the rate of surgical site infection (SSI) in low-risk patients undergoing orthopaedic surgery. We designed a simple scorecard to grade SSI risk factors and determined whether routine antibiotic prophylaxis affects SSI occurrence during open reduction and internal fixation (ORIF) orthopaedic surgeries in trauma patients at low risk of developing SSI. The SSI risk scorecard (possible total points ranged from 5 to 25) was designed to take into account a patient's general health status, the primary cause of fractures, surgical site tissue condition or wound class, types of devices implanted, and surgical duration. Patients with a low SSI risk score (≤8 points) who were undergoing clean ORIF surgery were divided into control (routine antibiotic treatment, cefuroxime) and evaluation (no antibiotic treatment) groups and followed up for 13-17 months after surgery. The infection rate was much higher in patients with high SSI risk scores (≥9 points) than in patients with low risk scores assigned to the control group (10.7% vs. 2.2%, Prisk score. Implementation of this scoring system could guide the rational use of perioperative antibiotics and ultimately reduce antibiotic resistance, health care costs, and adverse reactions to antibiotics.

    Empirical antibiotics at the onset of febrile neutropenia are one of several strategies for management of bacterial infections in patients undergoing Hematopoietic Stem Cell Transplant (HSCT) (empiric strategy). Our HSCT program aims to perform HSCT in an outpatient setting, where an empiric antibiotic strategy was employed. HSCT recipients began receiving intravenous antibiotics at the onset of neutropenia in the absence of fever as part of our institutional policy from 01 Jan 2009; intravenous Prophylactic strategy. A prospective study was conducted to compare two consecutive cohorts [Year 2008 (Empiric strategy) vs. Year 2009 (Prophylactic strategy)] of patients receiving HSCT. There were 238 HSCTs performed between 01 Jan 2008 and 31 Dec 2009 with 127 and 111 in the earlier and later cohorts respectively. Infection-related mortality pre- engraftment was similar with a prophylactic compared to an empiric strategy (3.6% vs. 7.1%; p = 0.24), but reduced among recipients of autologous HSCT (0% vs. 6.8%; p = 0.03). Microbiologically documented, blood stream infections and clinically documented infections pre-engraftment were reduced in those receiving a prophylactic compared to an empiric strategy, (11.7% vs. 28.3%; p = 0.001), (9.9% vs. 24.4%; p = 0.003) and (18.2% vs. 33.9% p = 0.007) respectively. The prophylactic use of intravenous once-daily ceftriaxone in patients receiving outpatient based HSCT is safe and may be particularly effective in patients receiving autologous HSCT. Further studies are warranted to study the impact of this Prophylactic strategy in an outpatient based HSCT program. PMID:23029441

  18. Antibiotic susceptibility, heteroresistance, and updated treatment strategies in Helicobacter pylori infection.

    2017-01-01

    In this review, we discuss the problem of antibiotic resistance, heteroresistance, the utility of cultures and antibiotic susceptibility tests in Helicobacter pylori ( Hp ) eradication, as well as the updated treatment strategies for this infection. The prevalence of antibiotic resistance is increasing all over the world, especially for metronidazole and clarithromycin, because of their heavy use in some geographical areas. Heteroresistance (simultaneous presence of both susceptible and resistant strains in different sites of a single stomach) is another important issue, as an isolate could be mistakenly considered susceptible if a single biopsy is used for antimicrobial tests. We also examined literature data regarding eradication success rates of culture-guided and empiric therapies. The empiric therapy and the one based on susceptibility testing, in Hp eradication, may depend on several factors such as concomitant diseases, the number of previous antibiotic treatments, differences in bacterial virulence in individuals with positive or negative cultures, together with local antibiotic resistance patterns in real-world settings. Updated treatment strategies in Hp infection presented in the guidelines of the Toronto Consensus Group (2016) are reported. These suggest to prolong eradication therapy up to 14 days, replacing the old triple therapy with a quadruple therapy based on proton pump inhibitor (PPI), bismuth, metronidazole, and tetracycline for most of the patients, or as an alternative quadruple therapy without bismuth, based on the use of PPI, amoxicillin, metronidazole, and clarithromycin. The new drug vonoprazan, a first-in-class potassium-competitive acid blocker recently approved in Japan, is also considered to be a promising solution for Hp eradication, even for clarithromycin-resistant strains. Furthermore, there is growing interest in finding new therapeutic strategies, such as the development of vaccines or the use of natural resources, including

    Peeraully, R; Henderson, K; Davies, B

    2016-04-01

    Introduction In England, emergency readmissions within 30 days of hospital discharge after an elective admission are not reimbursed if they do not meet Payment by Results (PbR) exclusion criteria. However, coding errors could inappropriately penalise hospitals. We aimed to assess the accuracy of coding for emergency readmissions. Methods Emergency readmissions attributed to paediatric surgery and urology between September 2012 and August 2014 to our tertiary referral centre were retrospectively reviewed. Payment by Results (PbR) coding data were obtained from the hospital's Family Health Directorate. Clinical details were obtained from contemporaneous records. All readmissions were categorised as appropriately coded (postoperative or nonoperative) or inappropriately coded (planned surgical readmission, unrelated surgical admission, unrelated medical admission or coding error). Results Over the 24-month period, 241 patients were coded as 30-day readmissions, with 143 (59%) meeting the PbR exclusion criteria. Of the remaining 98 (41%) patients, 24 (25%) were inappropriately coded as emergency readmissions. These readmissions resulted in 352 extra bed days, of which 117 (33%) were attributable to inappropriately coded cases. Conclusions One-quarter of non-excluded emergency readmissions were inappropriately coded, accounting for one-third of additional bed days. As a stay on a paediatric ward costs up to £500 a day, the potential cost to our institution due to inappropriate readmission coding was over £50,000. Diagnoses and the reason for admission for each care episode should be accurately documented and coded, and readmission data should be reviewed at a senior clinician level.

    2010-09-15

    The evolution of methicillin-resistant and vancomycin-resistant Staphylococcus aureus has demanded serious review of antimicrobial use and development of new agents and revised approaches to prevent and overcome drug resistance. Depending on local conditions and patient risk factors, empirical therapy of suspected S. aureus infection may require coverage of drug-resistant organisms with newer agents and novel antibiotic combinations. The question of treatment with inappropriate antibiotics raises grave concerns with regard to methicillin-resistant S. aureus selection, overgrowth, and increased virulence. Several strategies to reduce the nosocomial burden of resistance are suggested, including shortened hospital stays and outpatient parenteral antimicrobial therapy of the most serious infections.

  3. Antibiotic use during the intracoelomic implantation of electronic tags into fish

    The use of antibiotics, in particular, the use of a single dose of antibiotics during electronic tag implantation is of unproven value, and carries with it the potential for the development of antibiotic resistance in bacteria and the alteration of the immune response of the fish. Antibiotic use during electronic tag implantation must conform to relevant drug laws and regulations in the country where work is being done, including the requirements for withdrawal times before human consumption is a possibility. Currently, the choice of antibiotics (most often tetracycline or oxytetracycline) and the use of a single dose of the drug are decisions made without knowledge of the basic need for antibiotic usage and of the bacteria involved in infections that occur following electronic tag implantation. Correct perioperative use of an antibiotic is to apply the drug to the animal before surgery begins, to assure serum and tissue levels of the drug are adequate before the incision is made. However, the most common perioperative application of antibiotics during implantation of an electronic tag is to delay the administration of the drug, injecting it into the coelom after the electronic tag is inserted, just prior to closure of the incision. There is little empirical evidence that the present application of antibiotics in fish being implanted with electronic tags is of value. Improvements should first be made to surgical techniques, especially the use of aseptic techniques and sterilized instruments and electronic tags, before resorting to antibiotics. ?? 2010 Springer Science+Business Media B.V.(outside the USA).

  4. Frequent Home Monitoring of ICD Is Effective to Prevent Inappropriate Defibrillator Shock Delivery

    Directory of Open Access Journals (Sweden)

    2014-01-01

    Full Text Available Recently, in the context of telemedicine, telemonitoring services are gaining attention. They are offered, for example, to patients with implantable cardioverter defibrillators (ICDs. A major problem associated with ICD therapy is the occurrence of inappropriate shocks which impair patients’ quality of life and may also be arrhythmogenic. The telemonitoring can provide a valid support to intensify followup visits, in order to improve the prevention of inappropriate defibrillator shock, thus enhancing patient safety. Inappropriate shock generally depends on atrial fibrillation, supraventricular tachycardia, and abnormal sensing (such as those caused by electromagnetic interferences. As a practical example, an unusual case of an ICD patient who risked an inappropriate shock while taking a shower is reported. Continuous remote telemonitoring was able to timely warn cardiologist via GSM-SMS, who were able to detect improper sensing examining the intracardiac electrogram via Web. Patient was promptly contacted and warned to not further come in contact with the hydraulic system and any electrical appliance to prevent an inappropriate defibrillator shock. This demonstrates the effectiveness and usefulness of continuous remote telemonitoring in supporting ICD patients.

    Full Text Available Optimizing antibiotic prescribing across the surgical pathway (before, during, and after surgery is a key aspect of tackling important drivers of antimicrobial resistance and simultaneously decreasing the burden of infection at the global level. In the UK alone, 10 million patients undergo surgery every year, which is equivalent to 60% of the annual hospital admissions having a surgical intervention. The overwhelming majority of surgical procedures require effectively limited delivery of antibiotic prophylaxis to prevent infections. Evidence from around the world indicates that antibiotics for surgical prophylaxis are administered ineffectively, or are extended for an inappropriate duration of time postoperatively. Ineffective antibiotic prophylaxis can contribute to the development of surgical site infections (SSIs, which represent a significant global burden of disease. The World Health Organization estimates SSI rates of up to 50% in postoperative surgical patients (depending on the type of surgery, with a particular problem in low- and middle-income countries, where SSIs are the most frequently reported healthcare-associated infections. Across European hospitals, SSIs alone comprise 19.6% of all healthcare-acquired infections. Much of the scientific research in infection management in surgery is related to infection prevention and control in the operating room, surgical prophylaxis, and the management of SSIs, with many studies focusing on infection within the 30-day postoperative period. However it is important to note that SSIs represent only one of the many types of infection that can occur postoperatively. This article provides an overview of the surgical pathway and considers infection management and antibiotic prescribing at each step of the pathway. The aim was to identify the implications for research and opportunities for system improvement.

    Blood is a critical aspect of treatment in life saving situations, increasing demand. Blood requisition practices greatly effect sufficient supply in blood banks. This study aimed to determine the risk factors for inappropriate blood requisition in Tanzania. This was a cross sectional study using secondary data of 14,460 patients' blood requests from 42 transfusion hospitals. Primary data were obtained by using cluster-sampling design. Data were analysed using a two-level mixed-effects Poisson regression to determine fixed-effects of individual-level factors and hospital level factors associated with inappropriate blood requests. P-value Factors significantly associated with inappropriate requisition were; reporting pulse rate and capillary refill decrease the risk (RR 0.74; 95% CI 0.64, 0.84) and (RR 0.73; 95% CI 0.63, 0.85) respectively and the following increased the risk; having surgery during hospital stay (RR 1.22; 95% CI 1.06, 1.4); being in general surgical ward (RR 3.3; 95% CI 2.7, 4.2), paediatric ward (RR 1.8; 95% CI 1.2, 2.7), obstetric ward (RR 2.5; 95% CI 2.0, 3.1), gynaecological ward (RR 2.1; 95% CI 1.5, 2.9), orthopaedics ward (RR 3.8; 95% CI 2.2, 6.7). Age of the patient, pallor and confirmation of pre-transfusion haemoglobin level were also significantly associated with inappropriate requisition. Majority of appropriate requisitions within the wards were marked in internal medicine (91.7%) and gynaecological wards (77.8%). The proportion of inappropriate blood requests was high. Blood requisition was determined by clinical and laboratory findings and the ward patients were admitted to. Adherence to transfusion guidelines is recommended to assure the best use of limited blood supply.

    To describe the use of carbapenems in children hospitalised outside intensive care and onco-haematology units, and assess adherence to a therapeutic protocol. A retrospective observational study was conducted on the use of carbapenems between January 2009 and December 2010. The study included children with a community-acquired infectious disease or a health care-associated infectious disease, and who were admitted to paediatric areas of the Vall d'Hebron University Hospital (Barcelona, Spain), other than intensive care, neonatology and onco-haematology units. Clinical data were collected and antibiotic consumption data were provided by the Pharmacy Department. A total of 51 episodes fulfilled the inclusion criteria. Carbapenem as initial empirical treatment was indicated in 31.4%, and applied as rescue therapy in the remainder. The instructions of the protocol were adhered to in 70.6% of the empirical and 87.5% of the targeted prescriptions (77.6% overall). A better match was found for empirical carbapenem in patients with a previous admission or underlying condition. Factors such as diagnosis, age or antibiotic use prior to admission did not affect the empirical indication of carbapenem. The establishment of a treatment protocol with carbapenem indications in our centre since 2007 has yielded significantly better results on the appropriateness of the prescription than those obtained in other studies.

    Inappropriate antibiotic (ATB) prescriptions are a threat to patients, leading to adverse drug reactions, bacterial resistance, and subsequently, elevated hospital costs. Our aim was to evaluate ATB prescriptions in an emergency department of a tertiary care facility. A cross-sectional study was conducted by reviewing charts of patients complaining of infections. Patient characteristics (age, sex, weight, allergy, infection type) and prescription characteristics (class, dose, frequency, duration) were evaluated for appropriateness based on the AHFS Drug Information and the Drug Information Handbook. Descriptive and analytic statistics were applied. Sample with equal sex distribution constituted of 5,752 cases: adults (≥15 years) =61% and pediatrics (tract infections, 25% urinary tract infections (UTIs), and 20% others. Broad-spectrum coverage ATBs were prescribed for 76% of the cases. Before the prescription, 82% of pediatrics had their weight taken, while 18% had their weight estimated. Allergy checking was done in 8% only. Prevalence of inappropriate ATB prescriptions with at least one type of error was 46.2% (pediatrics =58% and adults =39%). Errors were in ATB selection (2%), dosage (22%), frequency (4%), and duration (29%). Dosage and duration errors were significantly predominant among pediatrics (Ppredictors of inappropriate prescriptions were associated with: 1) cephalosporin prescriptions (adults: Ppediatrics: Ppediatrics: P=0.039, adj OR =0.73) compared to respiratory tract infections; 3) obtaining weight for pediatrics before the prescription of ATB (Pinfections.

    Antimicrobial therapy for intra-abdominal infections is often inappropriately prolonged. An intervention addressing factors influencing the duration of intravenous antibiotic use was undertaken. This study reports the antibiotic prescribing patterns before and after the intervention and a qualitative analysis of the experience of the intervention. Quantitative: A retrospective audit of patients with complicated intra-abdominal infection before and after a multifaceted persuasive intervention was performed. Qualitative: Semi-structured interviews were performed to evaluate which elements of the intervention were perceived to be effective. An intervention including collaborative inter-specialty and inter-professional educational meetings, and education of all professional streams was undertaken. Quantitative: Twenty-three patients before and 22 patients after the intervention were included. The total duration of antibiotics decreased significantly following the intervention (9.2 versus 6.6 days P = 0.02). The duration of intravenous antibiotics did not change significantly (5.4 versus 4.5 days, P = 0.06). Qualitative: Eighteen health-care professionals participated. Thematic analysis indicated that a collaborative approach between senior surgical and infectious disease specialists in the pre-intervention stage led to perceived ownership and leadership of the intervention by the surgical team, which was thought critical to the success of the intervention. Conversely, the ability of nurses and pharmacists to influence antibiotic practice was considered limited and a poster promoting the intervention was perceived as ineffective. Consultant leadership and specialty ownership of the process were perceived to be critical in the success of the intervention. Antibiotic stewardship programs which address social factors may have greater efficacy to optimize antimicrobial prescribing. © 2018 Royal Australasian College of Surgeons.

    Appropriate use criteria (AUC) for transthoracic echocardiography (TTE) were developed to address concerns regarding inappropriate use of TTE. A previous pilot study suggests that an educational and feedback intervention can reduce inappropriate TTEs ordered by physicians in training. It is unknown if this type of intervention will be effective when targeted at attending level physicians in a variety of clinical settings. The aim of this international, multicenter study is to evaluate the hypothesis that an AUC-based educational and feedback intervention will reduce the proportion of inappropriate echocardiograms ordered by attending physicians in the ambulatory environment. In an ongoing multicentered, investigator-blinded, randomized controlled trial across Canada and the United States, cardiologists and primary care physicians practicing in the ambulatory setting will be enrolled. The intervention arm will receive (1) a lecture outlining the AUC and most recent available evidence highlighting appropriate use of TTE, (2) access to the American Society of Echocardiography mobile phone app, and (3) individualized feedback reports e-mailed monthly summarizing TTE ordering behavior including information on inappropriate TTEs and brief explanations of the inappropriate designation. The control group will receive no education on TTE appropriate use and order TTEs as usual practice. The Echo WISELY (Will Inappropriate Scenarios for Echocardiography Lessen Significantly in an education RCT) study is the first multicenter randomized trial of an AUC-based educational intervention. The study will examine whether an education and feedback intervention will reduce the rate of outpatient inappropriate TTEs ordered by attending level cardiologists and primary care physicians (www.clinicaltrials.gov identifier NCT02038101).

  12. Antibiotic use for upper respiratory tract infections in children: A cross-sectional survey of knowledge, attitudes, and practices (KAP) of parents in Greece

    Science.gov (United States)

    2011-01-01

    Background Upper respiratory tract infections (URTIs) are common in children. The cause of URTIs is usually viral, but parents' attitudes often contribute to inappropriate prescription of antibiotics, promoting antibiotic resistance. The objective of this study was to document and analyse parental beliefs on antibiotic use for children with URTIs in Greece, a country with high levels of antibiotic use and antibiotic resistance. Methods A knowledge-attitude-practice questionnaire was developed and distributed to Greek parents caring for children who were 5-6 years old, between January and July of the same school year. The sample of the study contained parents from all geographic areas of Greece. Results The majority of Greek parents (80%) believed that UTRIs are mostly self-limited, although 74% of them expected to receive antibiotics when such a diagnosis was given. Earache was the most common reason for which parents expected antibiotics (45%). Greek parents rarely gave antibiotics to their children without medical advice (10%) and most (88%) believed that unnecessary antibiotic use drives antibiotic resistance and they were happy to receive symptomatic therapy if instructed by their physician. Almost 70% of parents confused antibiotics with other medicines used for symptomatic therapy for a child with URTI. Conclusion Greek parents have a trusted relationship with their paediatrician and rarely give antibiotics without medical advice, indicating that parents contribute less than expected to antibiotic misuse. Parents also appreciate the benign course of most URTIs and the fact that unnecessary antibiotic use is harmful. More time needs to be invested in educating mostly physicians on the potential benefit from reducing antibiotic prescribing for children with URTI. PMID:21729266

    Inappropriate communications can cause a lack of necessary information exchange between operators and lead to serious consequences in large process systems such as nuclear power plants (NPPs). In this regard, various kinds of taxonomies of inappropriate communications have been developed to prevent inappropriate communications. However, there seems to be difficult to identify inappropriate communications from verbal protocol data between operators. Because the existing taxonomies were developed for use in report analysis, there is a problem of 'uncertainty'. In consequence, this paper proposes a new taxonomy of inappropriate communications and provides some insights to prevent inappropriate communications. In order to develop the taxonomy, existing taxonomies for four industries from 1980 to 2010 were collected and a new taxonomy is developed based on the simplified one-way communication model. In addition, the ratio of inappropriate communications from 8 samples of audio-visual format verbal protocol data recorded during emergency training sessions by operating teams is compared with performance scores calculated based on the task analysis. As a result, inappropriate communications can be easily identified from the verbal protocol data using the suggested taxonomy, and teams with a higher ratio of inappropriate communications tend to have a lower performance score.

    Evaluate the resistance of community-uropathogen, Escherichia coli to several antibiotics in our health sector and deduce empirical treatment options. E. coli strains isolated from urine cultures of patients from Primary Care Barbastro Sector, between January 2011 and December 2013, were studied. The resistances rates for nine common antibiotics were determined, and differences in sensitivity were analyzed, comparing confidence intervals for proportions by the method of Wilson. E. coli was the most frequently isolated bacteria (61.08% of positive urine cultures sent from Primary Care). Overall, there has been an increase in resistance of E. coli isolates in all antimicrobials studied. Still, resistance has remained below 4% compared to fosfomycin and nitrofurantoin and below 10% in cephalosporins second and third generation. Resistance to amoxicillin-clavulanate has increased progressively reaching 21.5% in 2013; only this antibiotic has presented a statistically significant increase. The maximum levels of resistance (over 30%) were found in the antibiotics administered orally and often indicated in uncomplicated urinary tract infections: trimethoprim-sulfamethoxazole, ciprofloxacin and ampicillin. Update knowledge susceptibility patterns of microorganisms most commonly isolated in urine samples in each health area allows to choose the most suitable and effective treatments trough empirical knowledge.

    Inappropriate use of antibiotics increases resistance and reduces their effectiveness. Despite evidence-based guidelines, antibiotics are still commonly used to treat infections likely caused by respiratory viruses. In this study, we examined the temporal relationships between antibiotic usage and respiratory infections in the Republic of Korea. The number of monthly antibiotic prescriptions and the incidence of acute respiratory tract infections between 2010 and 2015 at all primary care clinics were obtained from the Korean Health Insurance Review and Assessment Service. The monthly detection rates of respiratory viruses, including adenovirus, respiratory syncytial virus, influenza virus, human coronavirus, and human rhinovirus, were collected from Korea Centers for Disease Control and Prevention. Cross-correlation analysis was conducted to quantify the temporal relationship between antibiotic use and respiratory virus activities as well as respiratory infections in primary clinics. The monthly use of different classes of antibiotic, including penicillins, other beta-lactam antibacterials, macrolides and quinolones, was significantly correlated with influenza virus activity. These correlations peaked at the 0-month lag with cross-correlation coefficients of 0.45 ( p  < 0.01), 0.46 ( p  < 0.01), 0.40 ( p  < 0.01), and 0.35 (< 0.01), respectively. Furthermore, a significant correlation was found between acute bronchitis and antibiotics, including penicillin (0.73, p  < 0.01), macrolides (0.74, p  < 0.01), and quinolones (0.45, p  < 0.01), at the 0-month lag. Our findings suggest that there is a significant temporal relationship between influenza virus activity and antibiotic use in primary clinics. This relationship indicates that interventions aimed at reducing influenza cases in addition to effort to discourage the prescription of antibiotics by physicians may help to decrease unnecessary antibiotic consumption.

    In Germany a list was drawn up that included 83 potentially inappropriate drugs. The PRISCUS list published in 2010 was intended to highlight certain problems in the pharmakotherapy of elderly patients and serve as a support for improved medicine safety. Almost a third of the insurance portfolio of the HALLESCHE Krankenversicherung aged over 75 years takes drugs that are on the PRISCUS list. Benzodiazepine and Z-drugs are taken most frequently. The costs per insurant with potentially inappropriate medication are on average higher than for policyholders who do not take drugs on the PRISCUS list. The costs per insurant are rising, with an increase in the number of PRISCUS agents being taken as well. However, there is still no scientific proof that potentially inappropriate drugs lead to adverse drug events.

    Suicide is a leading cause of death among adolescents globally, and body weight is also a recognized reason for adolescent suicide. Therefore, we investigated the association between weight control behaviors (WCB) and suicide ideation and attempt, focusing on inappropriate weight control measures. We used data from the 2014 Korea Youth Risk Behavior Web-based Survey, representing a total of 35,224 boys and 34,361 girls aged 12 to 18 years. Adolescents were classified into groups based on WCB: appropriate WCB, inappropriate WCB, and no WCB. We performed logistic regression models to examine associations between WCB and suicide ideation and attempt, controlling for covariates. Both boys and girls with inappropriate WCB were more likely to report suicide ideation and attempt. Underweight and normal weight boys with inappropriate WCB were more likely to think or attempt suicide, and underweight girls with inappropriate WCB were also more likely to attempt suicide. Among five common WCB combinations, the combination of "regular exercise, fasting, eating less" was highly associated with suicide ideation and attempt. We confirmed that inappropriate WCB is associated with suicide ideation and attempt among Korean adolescents. Given the high incidence rate of suicide among adolescents and the adverse effect of inappropriate WCB, encouraging adolescents to control their weight in healthy ways is imperative.

    The increasing complexity of procedures in the intensive care unit (ICU) requires complex software services, to reduce improper use of antibiotics and inappropriate therapies, and to offer earlier and more accurate detection of infections and antibiotic resistance. We investigated whether web-based software can facilitate the computerization of complex medical processes in the ICU. The COSARA application contains the following modules: Infection overview, Thorax, Microbiology, Antibiotic therapy overview, Admission cause with comorbidity and admission diagnosis, Infection linking and registration, and Feedback. After the implementation and test phase, the COSARA software was installed on a physician's office PC and then on the bedside PCs of the patients. Initial evaluation indicated that the services had been integrated easily into the daily clinical workflow of the medical staff. The use of a service oriented architecture with web service technology for the development of advanced decision support in the ICU offers several advantages over classical software design approaches.

    Seven out of nine patients with chronic inappropriate secretion of antidiuretic hormone were successfully treated with 40 mg frusemide daily. One patient needed 80 mg, and the remaining patient achieved only a small increase in diuresis after 40 mg frusemide; this was probably related to his low creatinine clearance. In order to maintain a salt intake high enough to compensate for the loss of urine electrolytes 3 to 6 g sodium chloride was added as tablets to the sodium-free diet in six patients. Hypokalaemia occurred in five patients but was easily corrected with either supplements of potassium chloride or a potassium-sparing diuretic. These findings add further weight to evidence that Frusemide is a good alternative for the treatment of patients with inappropriate secretion of antidiuretic hormone who cannot tolerate water restriction.

    We characterize the current national patterns of antibiotic resistance of outpatient pediatric urinary tract infection. We examined outpatient urinary isolates from patients younger than 18 years in 2009 using The Surveillance Network®, a database with antibiotic susceptibility results and patient demographic data from 195 United States hospitals. We determined the prevalence and antibiotic resistance patterns for the 6 most common uropathogens, ie Escherichia coli, Proteus mirabilis, Klebsiella, Enterobacter, Pseudomonas aeruginosa and Enterococcus. We compared differences in uropathogen prevalence between males and females using chi-square analysis. We identified 25,418 outpatient urinary isolates. E. coli was the most common uropathogen overall but the prevalence of E. coli was higher among females (83%) than males (50%, p Resistance among E. coli was highest for trimethoprim-sulfamethoxazole (24%) but lower for nitrofurantoin (less than 1%) and cephalothin (15%). Compared to 2002 Surveillance Network data, E. coli resistance rates increased for trimethoprim-sulfamethoxazole (from 23% to 31% in males and from 20% to 23% in females) and ciprofloxacin (from 1% to 10% and from 0.6% to 4%, respectively). E. coli remains the most common pediatric uropathogen. Although widely used, trimethoprim-sulfamethoxazole is a poor empirical choice for pediatric urinary tract infections in many areas due to high resistance rates. First-generation cephalosporins and nitrofurantoin are appropriate narrow-spectrum alternatives given their low resistance rates. Local antibiograms should be used to assist with empirical urinary tract infection treatment. Copyright © 2013 American Urological Association Education and Research, Inc. Published by Elsevier Inc.

    2017-09-01

    Full Text Available Background: Urinary tract infections (UTIs in children are among the most common bacterial infections. Community-acquired urinary tract infections (CAUTI are often treated empirically with broad-spectrum antibiotics. Pattern of aetiologic agents and their antibiotic sensitivity may vary according to geographical and regional location. So, knowledge of antibiotic resistance trends is important for improving evidence-based recommendations for empirical treatment of UTIs. Objectives: To determine the common bacterial aetiologies of CAUTIs and their antibiotic resistance patterns in a tertiary care hospital, Savar. Materials and Methods: This cross-sectional descriptive study was conducted at Enam Medical College Hospital, Savar from May 2016 to April 2017. We collected clean-catch mid-stream urine samples from 257 patients having clinical diagnosis of UTI and submitted to the clinical microbiology laboratory for culture and sensitivity. Results: A total of 120 (46.7% samples were positive for bacterial growth. Escherichia coli (79% was the most common pathogen, followed by Klebsiella spp. (14%. Bacterial isolates showed high prevalence of resistance to multiple antibiotics. Resistance against amoxicillin/clavulanic acid, co-trimoxazole and ciprofloxacin was higher compared to newer quinolones and aminoglycosides. Conclusion: Esch. coli and Klebsiella spp. were the predominant bacterial pathogens. The resistance pattern to commonly prescribed antibiotics was quite high and alarming.

    Full Text Available INTRODUCTION: The ageing population means prescribing for chronic illnesses in older people is expected to rise. Comorbidities and compromised organ function may complicate prescribing and increase medication-related risks. Comorbid depression in older people is highly prevalent and complicates medication prescribing decisions. AIM: To determine the prevalence of potentially inappropriate medication use in a community-dwelling population of older adults with depressive symptoms. METHODS: The medications of 191 community-dwelling older people selected because of depressive symptoms for a randomised trial were reviewed and assessed using the modified version of the Beers' Criteria. The association between inappropriate medication use and various population characteristics was assessed using Chi-square statistics and logistic regression analyses. RESULTS: The mean age was 81 (±4.3 years and 59% were women. The median number of medications used was 6 (range 1-21 medications. The most commonly prescribed potentially inappropriate medications were amitriptyline, dextropropoxyphene, quinine and benzodiazepines. Almost half (49% of the participants were prescribed at least one potentially inappropriate medication; 29% were considered to suffer significant depressive symptoms (Geriatric Depression Scale ≥5 and no differences were found in the number of inappropriate medications used between those with and without significant depressive symptoms (Chi-square 0.005 p=0.54. DISCUSSION: Potentially inappropriate medication use, as per the modified Beers' Criteria, is very common among community-dwelling older people with depressive symptoms. However, the utility of the Beers' Criteria is lessened by lack of clinical correlation. Ongoing research to examine outcomes related to apparent inappropriate medication use is needed.

    Full Text Available In recent decades, the elderly population in Brazil has grown rapidly, as has concern for the health of this population. Institutionalization in nursing homes has appeared as an alternative form of health care for frail elderly that live alone. The present study evaluated the pharmacotherapy and inappropriate drug prescriptions for institutionalized elderly patients living in long-term institutions in southeastern Brazil. This research was conducted at five institutions with a total sample of 151 individuals aged at least 60 years. Databases were used to identify drug interactions, defined daily dose and inappropriate prescriptions. The prevalence of drug intake among the elderly was 95.36%, and there were an average of 3.31 ± 1.80 drug prescriptions per individual. Based on Beers criteria, the prevalence of inappropriate prescriptions was 25.83%. In addition, 70.2% of prescriptions were prescribed at a higher dosage than the defined daily dose (ATC/WHO. Potential drug interactions were identified for 54.11% of prescriptions; 81.42% of these were of moderate severity. The main inappropriate drugs were prescribed for cardiovascular and nervous system problems. Institutionalized elderly individuals presented a high consumption and misuse of medications, requiring professional intervention to monitor prescriptions and improve the quality of service for this population.

  7. Electromagnetic Interference from Swimming Pool Generator Current Causing Inappropriate ICD Discharges

    Full Text Available Electromagnetic interference (EMI includes any electromagnetic field signal that can be detected by device circuitry, with potentially serious consequences: incorrect sensing, pacing, device mode switching, and defibrillation. This is a unique case of extracardiac EMI by alternating current leakage from a submerged motor used to recycle chlorinated water, resulting in false rhythm detection and inappropriate ICD discharge. A 31-year-old female with arrhythmogenic right ventricular cardiomyopathy and Medtronic dual-chamber ICD placement presented after several inappropriate ICD shocks at the public swimming pool. Patient had never received prior shocks and device was appropriate at all regular follow-ups. Intracardiac electrograms revealed unique, high-frequency signals at exactly 120 msec suggestive of EMI from a strong external source of alternating current. Electrical artifact was incorrectly sensed as a ventricular arrhythmia which resulted in discharge. ICD parameters including sensing, pacing thresholds, and impedance were all normal suggesting against device malfunction. With device failure and intracardiac sources excluded, EMI was therefore strongly suspected. Avoidance of EMI source brought complete resolution with no further inappropriate shocks. After exclusion of intracardiac interference, device malfunction, and abnormal settings, extracardiac etiologies such as EMI must be thoughtfully considered and excluded. Elimination of inappropriate shocks is to “first, do no harm.”

    Full Text Available While self-medication is common, inappropriate self-medication has potential risks. This study assesses inappropriate self-medication among adolescents and examines the relationships among medication literacy, substance use, and inappropriate self-medication.In 2016, a national representative sample of 6,226 students from 99 primary, middle, and high schools completed an online self-administered questionnaire. Multiple logistic regression analysis was used to examine factors related to inappropriate self-medication.The prevalence of self-medication in the past year among the adolescents surveyed was 45.8%, and the most frequently reported drugs for self-medication included nonsteroidal anti-inflammatory drugs or pain relievers (prevalence = 31.1%, cold or cough medicines (prevalence = 21.6%, analgesics (prevalence = 19.3%, and antacids (prevalence = 17.3%. Of the participants who practiced self-medication, the prevalence of inappropriate self-medication behaviors included not reading drug labels or instructions (10.1%, using excessive dosages (21.6%, and using prescription and nonprescription medicine simultaneously without advice from a health provider (polypharmacy (30.3%. The results of multiple logistic regression analysis showed that after controlling for school level, gender, and chronic diseases, the participants with lower medication knowledge, lower self-efficacy, lower medication literacy, and who consumed tobacco or alcohol were more likely to engage in inappropriate self-medication.Lower medication literacy and substance use were associated with inappropriate self-medication among adolescents.

    To identify the percentage of inappropriate lumbar spine magnetic resonance imaging in the Soria Health Service, to quantify the costs and the possible association between inadequate use, the characteristics of the patient and the services requested. A descriptive study of the inappropriate use of MRI of the lumbar spine, taken from the retrospective examination, carried out by a radiologist, of the 233 MRI's requested between 1995 and 1998. For the valuation, the criteria of the American College of Radiology (ACR) and the Basque Agency for the Evaluation of Technologies (OSTEBA) were used. All the MRI's were carried out at an approved centre, the costs were calculated taken form the expenses paid by the Insalud, including the transport costs, calculated at prices applicable for the year in question. 11.7% of the studies were values as inappropriate, 2.1% debatable and the remainder adequate according to the ACR criteria, concentrating the inadequacy on studies for lumbago, that reached 80% of the inappropriate requests. The ACR and OSTEBA criteria coincided to a high degree (kappa statistics: 0.87). The expense related to the unnecessary studies was a litter higher than a million pesetas. No differences were found in the proportion of inappropriate studies according to the characteristics of the patient or the service requested, except the one already mentioned for the supposition diagnosis. Although the results of the study cannot be generalised to other environments, they suggest the possibility of a significant proportion of inappropriate use of lumbar spine MRI that could have an important repercussion on health care expenses.

    Optimizing antibiotic prescribing across the surgical pathway (before, during, and after surgery) is a key aspect of tackling important drivers of antimicrobial resistance and simultaneously decreasing the burden of infection at the global level. In the UK alone, 10 million patients undergo surgery every year, which is equivalent to 60% of the annual hospital admissions having a surgical intervention. The overwhelming majority of surgical procedures require effectively limited delivery of antibiotic prophylaxis to prevent infections. Evidence from around the world indicates that antibiotics for surgical prophylaxis are administered ineffectively, or are extended for an inappropriate duration of time postoperatively. Ineffective antibiotic prophylaxis can contribute to the development of surgical site infections (SSIs), which represent a significant global burden of disease. The World Health Organization estimates SSI rates of up to 50% in postoperative surgical patients (depending on the type of surgery), with a particular problem in low- and middle-income countries, where SSIs are the most frequently reported healthcare-associated infections. Across European hospitals, SSIs alone comprise 19.6% of all healthcare-acquired infections. Much of the scientific research in infection management in surgery is related to infection prevention and control in the operating room, surgical prophylaxis, and the management of SSIs, with many studies focusing on infection within the 30-day postoperative period. However it is important to note that SSIs represent only one of the many types of infection that can occur postoperatively. This article provides an overview of the surgical pathway and considers infection management and antibiotic prescribing at each step of the pathway. The aim was to identify the implications for research and opportunities for system improvement. Copyright © 2017 The Author(s). Published by Elsevier Ltd.. All rights reserved.

    Information on the influence of pre-hospital antibiotic treatment on the causative organisms, clinical features and outcomes of patients with community-acquired pneumonia (CAP) remains scarce. We performed an observational study of a prospective cohort of non-immunosuppressed adults hospitalized with CAP between 2003 and 2012. Patients were divided into two groups: those who had received pre-hospital antibiotic treatment for the same episode of CAP and those who had not. A propensity score was used to match patients. Of 2179 consecutive episodes of CAP, 376 (17.3%) occurred in patients who had received pre-hospital antibiotic treatment. After propensity score matching, Legionella pneumophila was more frequently identified in patients with pre-hospital antibiotic treatment, while Streptococcus pneumoniae was less common (p sensitivity and specificity of the pneumococcal urinary antigen test for diagnosing pneumococcal pneumonia were similar in the two groups. Patients with pre-hospital antibiotic treatment were less likely to present fever (p 0.02) or leucocytosis (p 0.001). Conversely, chest X-ray cavitation was more frequent in these patients (p 0.04). No significant differences were found in the frequency of patients classified into high-risk Pneumonia Severity Index classes, in intensive care unit admission, or in 30-day mortality between the groups. In conclusion, L. pneumophila occurrence was nearly three times higher in patients who received pre-hospital antibiotics. After a propensity-adjusted analysis, no significant differences were found in prognosis between study groups. Pre-hospital antibiotic use should be considered when choosing aetiological diagnostic tests and empirical antibiotic therapy in patients with CAP. © 2013 The Authors Clinical Microbiology and Infection © 2013 European Society of Clinical Microbiology and Infectious Diseases.

  15. Steering Evolution with Sequential Therapy to Prevent the Emergence of Bacterial Antibiotic Resistance.

    2015-09-01

    Full Text Available The increasing rate of antibiotic resistance and slowing discovery of novel antibiotic treatments presents a growing threat to public health. Here, we consider a simple model of evolution in asexually reproducing populations which considers adaptation as a biased random walk on a fitness landscape. This model associates the global properties of the fitness landscape with the algebraic properties of a Markov chain transition matrix and allows us to derive general results on the non-commutativity and irreversibility of natural selection as well as antibiotic cycling strategies. Using this formalism, we analyze 15 empirical fitness landscapes of E. coli under selection by different β-lactam antibiotics and demonstrate that the emergence of resistance to a given antibiotic can be either hindered or promoted by different sequences of drug application. Specifically, we demonstrate that the majority, approximately 70%, of sequential drug treatments with 2-4 drugs promote resistance to the final antibiotic. Further, we derive optimal drug application sequences with which we can probabilistically 'steer' the population through genotype space to avoid the emergence of resistance. This suggests a new strategy in the war against antibiotic-resistant organisms: drug sequencing to shepherd evolution through genotype space to states from which resistance cannot emerge and by which to maximize the chance of successful therapy.

    The effects of heart failure (HF) severity on risk of inappropriate implantable cardioverter-defibrillator (ICD) therapy have not been thoroughly investigated. We aimed to study the association between HF severity and inappropriate ICD therapy in MADIT-RIT. MADIT-RIT randomized 1,500 patients to three ICD programming arms: conventional (Arm A), high-rate cut-off (Arm B: ≥200 beats/min), and delayed therapy (Arm C: 60-second delay for ≥170 beats/min). We evaluated the association between New York Heart Association (NYHA) class III (n = 256) versus class I-II (n = 251) and inappropriate ICD therapy in Arm A patients with ICD-only and cardiac resynchronization therapy with defibrillator (CRT-D). We additionally assessed benefit of novel ICD programming in Arms B and C versus Arm A by NYHA classification. In Arm A, the risk of inappropriate therapy was significantly higher in those with NYHA III versus NYHA I-II for both ICD (hazard ratio [HR] = 2.55, confidence interval [CI]: 1.51-4.30, P programming significantly reduced inappropriate therapy in patients with both NYHA III (Arm B vs Arm A: HR = 0.08, P programming with high-rate cut-off or delayed detection reduces inappropriate ICD therapies in both mild and moderate HF. © 2017 Wiley Periodicals, Inc.

    In Haiti, where all drugs are available over the counter, self-medication with antibiotics appears as a common practice. Inappropriate use of beta-lactams and macrolides is likely to contribute to the development of antimicrobial resistance. This study aimed to (i) assess the extent of self-medication with antibiotics, (ii) explore the contributing factors (age, gender and educational background) and (iii) identify specific antibiotic drug classes used among patients attending the outpatient clinic of the State University Hospital of Port-au-Prince. A cross-sectional survey among 200 outpatients of the State University Hospital of Port-au-Prince was conducted in December 2014. Face-to-face interviews were conducted using a standardized questionnaire. Parents of pediatric patients were allowed to answer to questions on their behalf. Among the study sample, 45.5% practiced self-medication with antibiotics. It was less prevalent among patients with the highest education level (23.1%; OR: 0.89 (0.5-1.75), p = 0.001). Mild symptoms (28.6%) and vaginal itching (44.4%) were the main reasons for self-medication with antibiotics. Self-medication using amoxicillin was reported by 67.0%. Self-medication with antibiotics is a common practice among Haitian patients and is more common among the less educated. Amoxicillin for urinary tract infections is the most commonly used medication. It is crucial to raise awareness on the dangers of the practice in the population and inforce the current law regarding the use of over the counter antibiotics.

The prevalence of antibiotic resistance is increasing all over the world, especially for metronidazole and clarithromycin, because of their heavy use in some geographical areas. Heteroresistance (simultaneous presence of both susceptible and resistant strains in different sites of a single stomach is another important issue, as an isolate could be mistakenly considered susceptible if a single biopsy is used for antimicrobial tests. We also examined literature data regarding eradication success rates of culture-guided and empiric therapies. The empiric therapy and the one based on susceptibility testing, in Hp eradication, may depend on several factors such as concomitant diseases, the number of previous antibiotic treatments, differences in bacterial virulence in individuals with positive or negative cultures, together with local antibiotic resistance patterns in real-world settings. Updated treatment strategies in Hp infection presented in the guidelines of the Toronto Consensus Group (2016 are reported. These suggest to prolong eradication therapy up to 14 days, replacing the old triple therapy with a quadruple therapy based on proton pump inhibitor (PPI, bismuth, metronidazole, and tetracycline for most of the patients, or as an alternative quadruple therapy without bismuth, based on the use of PPI, amoxicillin, metronidazole, and clarithromycin.

    Background. Proton pump inhibitors (PPIs) are currently the most effective agents for acid-related disorders. However, studies show that 25-75% of patients receiving intravenous PPIs had no appropriate justification, indicating high rates of inappropriate prescribing. Objective. To examine the appropriate use of intravenous PPIs in accordance with guidelines and the efficacy of a prescribing awareness intervention at an Asian teaching institution. Setting. Prospective audit in a tertiary hospital in Malaysia. Method. Every 4th intravenous PPI prescription received in the pharmacy was screened against hospital guidelines. Interventions for incorrect indication/dose/duration were performed. Patients' demographic data, medical history and the use of intravenous PPI were collected. Included were all adult inpatients prescribed intravenous PPI. Main Outcome Measure. Proportion of appropriate IV PPI prescriptions. Results. Data for 106 patients were collected. Most patients were male [65(61.3%)], Chinese [50(47.2%)], with mean age ± SD = 60.3 ± 18.0 years. Most intravenous PPI prescriptions were initiated by junior doctors from the surgical [47(44.3%)] and medical [42(39.6%)] departments. Only 50/106(47.2%) patients had upper gastrointestinal endoscopy/surgery performed to verify the source of bleeding. Unexplained abdominal pain [81(76.4%)] was the main driver for prescribing intravenous PPIs empirically, out of which 73(68.9%) were for suspected upper gastrointestinal bleed. Overall, intravenous PPI was found to be inappropriately prescribed in 56(52.8%) patients for indication, dose or duration. Interventions on the use of intravenous PPI were most effective when performed by senior doctors (100%), followed by clinical pharmacists (50%), and inpatient pharmacists (37.5%, p = 0.027). Conclusion. Inappropriate intravenous PPI usage is still prevalent despite the enforcement of hospital guidelines. The promotion of prescribing awareness and evidence-based prescribing

    Patients with septic shock by multidrug resistant microorganisms (MDR) are a specific sepsis population with a high mortality risk. The exposure to an initial inappropriate empiric antibiotic therapy has been considered responsible for the increased mortality, although other factors such as immune-paralysis seem to play a pivotal role. Therefore, beyond conventional early antibiotic therapy and fluid resuscitation, this population may benefit from the use of alternative strategies aimed at supporting the immune system. In this review we present an overview of the relationship between MDR infections and immune response and focus on the rationale and the clinical data available on the possible adjunctive immunotherapies, including blood purification techniques and different pharmacological approaches.

    Inappropriate use of antibiotics may lead to adverse side effects. This cross-sectional survey aimed to investigate the knowledge and attitude of female non-medical students regarding the medical and dental use of antibiotics. Four hundred validated self-administered questionnaires were distributed in Princess Norah Bint-Abdurrahman University, Riyadh, Saudi Arabia. The questionnaire included questions about accessibility, attitude toward usage, efficacy, side effects, resistance, and usage for dental issues. Knowledge was estimated for every respondent by counting the correct answers, which were considered as points. The scores were categorized as poor, moderate, and high. Of the respondents, 77.8% answered they get antibiotics according to a doctor's prescription; however, 31% stops taking antibiotics when they feel well. Only 38.8% of respondents knew that antibiotics may cause allergic reactions while 59.8% believed the human body can be resistant to antibiotics. The percentages of answers related to dental issues were: antibiotics relieve dental pain (68.8%), antibiotics can be harmful for children's teeth (27.3%), antibiotics are best avoided in pregnancy (56.7%) and no need for antibiotics after scaling (33.8%), root canal treatment (16%), or simple extraction (40.3%). Of respondents, 68% had poor scores about antibiotics efficacy, side effects, and resistance while 86.8% had poor scores related to dental problems. This study noticed a bad attitude related to antibiotics usage, with many misconceptions and poor knowledge. Moreover, the necessity of antibiotics for treatment of dental disease or after dental procedures was totally unclear for the respondents. Community campaigns are recommended every university semester to educate students about the indications, efficacy, and side effects of antibiotics. Copyright © 2017 The Authors.

  3. Development of botanicals to combat antibiotic resistance

    Full Text Available The discovery of antibiotics in the previous century lead to reduction in mortality and morbidity due to infectious diseases but their inappropriate and irrational use has resulted in emergence of resistant microbial populations. Alteration of target sites, active efflux of drugs and enzymatic degradations are the strategies employed by the pathogenic bacteria to develop intrinsic resistance to antibiotics. This has led to an increased interest in medicinal plants since 25–50% of current pharmaceuticals are plant derived. Crude extracts of medicinal plants could serve as an alternate source of resistance modifying agents owing to the wide variety of secondary metabolites. These metabolites (alkaloids, tannins, polyphenols etc. could act as potentials for antimicrobials and resistance modifiers. Plant extracts have the ability to bind to protein domains leading to modification or inhibition protein–protein interactions. This enables the herbals to also present themselves as effective modulators of host related cellular processes viz immune response, mitosis, apoptosis and signal transduction. Thus they may exert their activity not only by killing the microorganism but by affecting key events in the pathogenic process, thereby, the bacteria, fungi and viruses may have a reduced ability to develop resistance to botanicals. The article is meant to stimulate research wherein the cidal activity of the extract is not the only parameter considered but other mechanism of action by which plants can combat drug resistant microbes are investigated. The present article emphasizes on mechanisms involved in countering multi drug resistance.

    Unjustified antibiotic prescribing for acute upper respiratory infections (URTIs) is probably more common in poor-resource settings where physicians are scarce. Introducing C-reactive protein (CRP) point-of-care testing in such settings could reduce the misuse of antibiotics, which could avert antibiotic resistance. However, information useful for the applicability of CRP test in resource-limited settings is lacking. This study aimed to elicit the frequency of antibiotic prescribing and distribution of CRP levels in remote, rural settings in Ethiopia. We included 414 patients with acute URTIs from four health centres. Health professionals recorded the clinical features of the patients, but the laboratory professionals measured the CRP levels of all patients at the point of care. The most prominent respiratory causes for consultation were acute URTIs combined (44.4%), and lower respiratory tract infections-pneumonia (29.71%) and acute bronchitis (25.84%). The CRP distribution was Ethiopia is unduly high, with high proportions of mild, self-limiting illness, mostly URTIs. Implementation of CRP point-of-care testing in such resource-constrained settings, with low- or middle-grade healthcare professionals, could help reconcile the inappropriate use of antibiotics by withholding from patients who do not benefit from antibiotic treatment.

    Mastitis is a bacterial disease common in dairy farms. Although knowledge about mastitis and its optimal technical management and treatment is now available, some dairy farmers still use antibiotics in inappropriate ways. Antibiotic use by farmers can be influenced by personal restraints and motivations, but it can be assumed that external drivers are also influential. The main purpose of this article is thus to analyse the choices of antibiotic and alternative medicine use for mastitis treatment and investigate the possible influence of two unexplored external drivers in dairy farms: (i) the health advice offered to farmers by farm advisors and veterinarians, (ii) the dairy farming system, as defined by combining the market valuation chosen for the milk, the level of intensification, and the perceived pressure related to investments. Research was based on 51 individual semi-structured interviews with farmers and their corresponding veterinarians and farm advisors. Based on verbatim, the use of antibiotics and alternative medicine by farmers for mastitis treatment, the vet-farmers interactions, and the dairy farming systems are described. The advisory relationships between farmers and farm advisors and between farmers and veterinarians influenced the implementation of selective dry cow therapy, but had very little effect on the use of alternative medicines by farmers, who were more willing to experiment alternative medicines than their advisors. The dairy farming system had very little influence on antibiotic use: some misuse of antibiotics was found whatever the farming system. Systematic dry cow therapy was also a widespread habit in all dairy farming systems except organic. The use of alternative medicine was common in all farming systems. Copyright © 2017 Elsevier B.V.

    Full Text Available This research investigated the inappropriate behavior of preschool children with autism in a classroom and examined the effectiveness of the use of social stories to decrease inappropriate autistic behavior. An A-B-A-B single subject design was used across the five participants selected for the study. Investigating the problematic social skills and developing a social story intervention for the preschool autistic children was completed, followed by an examination of the effectiveness of the social story intervention. Ten common problematic social skills among the autistic children in preschool were identified—walking around, making loud noises, not sharing their toys with others, showing frustration when feeling unsatisfied, having no patience, not putting toys away when finished, taking other people's belongings without permission, not knowing how to greet others, destroying things when feeling frustrated, and giving a hug to other people at inappropriate times. It was found that the social story intervention helped to decrease inappropriate behavior in children with autism. The social story intervention consisted of five social story books and five e-books (one story per child using a single subject design with an A-B-A-B pattern. The autistic children preferred social stories from the hardcopy books compared with stories from the e-books. A fourth stage time trial was used over 6 weeks, five times per week, for a total of 30 times. The findings suggested that the use of properly constructed social stories can be effective in decreasing the inappropriate behavior of children with autism. However, each story intervention should be applied with caution because of individual differences between children. The social story intervention should be designed only for autistic children who exhibit specific inappropriate social behavior.

    The rates and reasons why clinicians decide not to follow recommendations from explicit-criteria have been studied scarce. We aimed to compare STOPP version 2 representing one of the most commonly used excplicit tool with the implicit comprehensive geriatric assessment mediated clinical evaluation considered as gold standard. Two hundred and six (n = 206) outpatients ≥65 years old were included. The study was designed as retrospective, cross-sectional, and randomised. STOPP version 2 criteria were systematically used to assess pre-admission treatments followed by implicit clinical evaluation regarding two questions: Were the STOPP criteria recommendations valid for the individual patient and were there any potentially inappropriate-prescription other than depicted by STOPP version 2 criteria? The underlying reason(s) and associated clinical-features were noted. About 62.6% potentially inappropriate-prescriptions were identified (0.6 per-subject) according to systematic application of STOPP v2 while it was 53.4% (0.5 potentially inappropriate-prescriptions per subject) by clinician's application of STOPP v2. Prevalence of non-compliance was 14.7% in 18 (21.7%) of 83 patients identified by systematic application. Suggestion to stop a drug was not accepted because of need of treatment despite likelihood of anticipated side-effects in about 2/3 and with no-anticipated side-effects in about 1/3 of non-compliances. Not following STOPP v2 was significantly associated with lower functional level. According to clinician's implicit-evaluation, there were an extra 59.2% potentially inappropriate-prescriptions (0.6 per subject) in 80 (38.8%) patients yielding a total of 112.6% potentially inappropriate-prescription. Most of the STOPP v2 directed drug cessations are decided valid by the clinicians. In patients with higher functional dependency, it is likely that they are not followed due to palliation focussed care/patient-family preferences. There may be as much as STOPP

The study was conducted with objectives to determine the prevalence of potentially inappropriate medicine (PIM prescribing in older Nepalese patients in a medicine outpatient department.Materials & Methods: A prospective observational analysis of drugs prescribed in medicine out-patient department (OPD of a tertiary hospital of central Nepal was conducted during November 2012 to October 2013 among 869 older adults aged 65 years and above. The use of potentially inappropriate medications (PIM in elderly patients was analysed using Beer’s Criteria updated to 2013. Results: In the 869 patients included, the average number of drugs prescribed per prescription was 5.56. The most commonly used drugs were atenolol (24.3%, amlodipine (23.16%, paracetamol (17.6%, salbutamol (15.72% and vitamin B complex (13.26%. The total number of medications prescribed was 4833. At least one instance of PIM was experienced by approximately 26.3% of patients when evaluated using the Beers criteria. Conclusion: Potentially inappropriate medications are highly prevalent among older patients attending medical OPD and are associated with number of medications prescribed. Further research is warranted to study the impact of PIMs towards health related outcomes in these elderly.

    The main objective of the study was to assess the adequacy of antibiotic therapy for urinary tract infections (UTI) in a French hospital medical department. The secondary objective was to identify factors associated with inadequacy of the antibiotic therapy. A retrospective single centre cohort study was performed in the Post-Emergency Medicine Department (PEMD) of the university hospital of Lille. All patients presenting with an UTI from May 2012 to April 2014 were included. Adequacy of antibiotic therapy was assessed with reference to local guidelines. Factors associated with inadequacy of antibiotic prescription were determined using a multivariate logistic regression model. Two hundred and twenty-eight patients were included. The antibiotic prescription was fully adequate in 173 patients (76%) with appropriate use of a single or a combination antibiotic therapy in 96%, appropriate drug in 80%, appropriate dosage in 89% and appropriate route of administration in 95%. The risk for antibiotic inadequacy was significantly higher in patients with cystitis than in those with pyelonephritis (OR 12.01; 95% CI 4.17-34.65), when antibiotics were prescribed in the Emergency Department (OR 6.84; 95% CI 2.29-20.47) or before hospital admission (OR 382.46; 95% CI 19.61≥999.99) compared to when antibiotics were first administered in the PEMD, and in patients with severe UTI (OR 19.55; 95% CI 2.79-137.01). Adequacy of antibiotic therapy for UTI is relatively high in our study, reflecting the effective dissemination of antibiotic guidelines. However, antibiotic therapy is still inappropriate in cystitis, severe UTI and in case of prescription before the admission in the PEMD.

    Antibiotics are among the most successful drugs used for human therapy. However, since they can challenge microbial populations, they must be considered as important pollutants as well. Besides being used for human therapy, antibiotics are extensively used for animal farming and for agricultural purposes. Residues from human environments and from farms may contain antibiotics and antibiotic resistance genes that can contaminate natural environments. The clearest consequence of antibiotic release in natural environments is the selection of resistant bacteria. The same resistance genes found at clinical settings are currently disseminated among pristine ecosystems without any record of antibiotic contamination. Nevertheless, the effect of antibiotics on the biosphere is wider than this and can impact the structure and activity of environmental microbiota. Along the article, we review the impact that pollution by antibiotics or by antibiotic resistance genes may have for both human health and for the evolution of environmental microbial populations. - The article reviews the current knowledge on the effects that pollution by antibiotics and antibiotic resistance genes may have for the microbiosphere.

    2017-01-01

    Full Text Available Background: Inappropriate use of antibiotics globally has been linked to increase in antibiotic resistance. Objectives: This interventional study assessed the impact of antibiotic prescription feedback and focus group discussions (FGD on hospital-based prescribers before and after the FGD. Study Design: The present study was performed at a tertiary care centre in New Delhi, wherein 45 units from surgical specialities were included for FGD. Thirty-five units were assessed for the antibiotic usage during 12 months pre-intervention and 3 and 6 months post-intervention period. The outcome measured was a change in antibiotic prescription rates reflected as daily defined doses per 100 bed days as defined by the World Health Organisation. Results: Reduction in the level of antibiotic consumption was observed in 15 of 35 units (42.85% during the 3 months post-intervention period, which was significant (P < 0.05 in 3/35 (8.57% surgical units. A significant reduction (P < 0.05 was observed for the units of endoscopic gynaecology, super-speciality and transplant surgery units B and C, and orthopaedic unit C during the 6 months period. Decreasing trend (P < 0.05 was observed in 2/35 (5.71% units during the entire period. Overall reduction of antibiotic consumption (1.88% was observed, with an increase in the use of low-end antibiotics and a decrease in the use of high-end antibiotics. Conclusion: The present study clearly demonstrates a weak impact of FGD in changing antibiotic prescribing behaviour. Further analysis of the sustainability of FGD and its long-term impact on antimicrobial resistance needs to be evaluated. The effect of continuous educational sessions and multifaceted interventions cannot be ignored.

    To introduce the reader to the fundamentals involved in using decision analysis as a tool in evaluating the associated costs and effectiveness of comparable therapeutic agents. Currently available literature citations were used to provide the reader with basic references whose purpose is to provide a step-by-step approach for using Decision Analysis in conducting a cost-effective comparison of three commonly used antibiotics. Data were gathered from a previously conducted retrospective chart review where the three antibiotics were used for either prophylactic, empiric, or documented infections. Although this study was limited by its retrospective nature, the reader can use the data to appreciate the fundamentals of decision analysis. The continually changing climate in healthcare and the added visibility of pharmacologic agents in the treatment and prevention of disease has increased pressure on pharmacy departments to provide therapeutic agents that are cost-effective. Decision analysis can be used to compare therapeutic agents, in terms of financial as well as clinical outcomes, in a structured fashion that all members of the health care team can understand. The application of Decision analysis is appropriate for many therapeutic agents, not just antibiotics.

    Early-life antibiotic exposure has been associated with increased adiposity in animal models, mediated through the gut microbiome. Infant antibiotic exposure is common and often inappropriate. Studies of the association between infant antibiotics and childhood weight gain have reported inconsistent results. To assess the association between early-life antibiotic exposure and childhood weight gain. Retrospective, longitudinal study of singleton births and matched longitudinal study of twin pairs conducted in a network of 30 pediatric primary care practices serving more than 200,000 children of diverse racial and socioeconomic backgrounds across Pennsylvania, New Jersey, and Delaware. Children born between November 1, 2001, and December 31, 2011, at 35 weeks' gestational age or older, with birth weight of 2000 g or more and in the fifth percentile or higher for gestational age, and who had a preventive health visit within 14 days of life and at least 2 additional visits in the first year of life. Children with complex chronic conditions and those who received long-term antibiotics or multiple systemic corticosteroid prescriptions were excluded. We included 38,522 singleton children and 92 twins (46 matched pairs) discordant in antibiotic exposure. Final date of follow-up was December 31, 2012. Systemic antibiotic use in the first 6 months of life. Weight, measured at preventive health visits from age 6 months through 7 years. Of 38,522 singleton children (50% female; mean birth weight, 3.4 kg), 5287 (14%) were exposed to antibiotics during the first 6 months of life (at a mean age of 4.3 months). Antibiotic exposure was not significantly associated with rate of weight change (0.7%; 95% CI, -0.1% to 1.5%; P = .07, equivalent to approximately 0.05 kg; 95% CI, -0.004 to 0.11 kg of added weight gain between age 2 years and 5 years).

    Compared to other infections, intraabdominal infections include wide spectrum of infections of various severity, have different ethiology, which is frequently polymicrobial, show different microbiological results, which are difficult to interpret. The role of surgical intervention is essential. Intraabdominal infections are common causes of morbidity and mortality. Their prognosis is significantly improved with early and exact diagnosis, appropriate surgical or radiological intervention and timely effective antimicrobial therapy. Practitioners may choose between older or more modern antibiotics, between monotherapy or combination therapy, however, they should also consider clinical condition of the patient, the antibiotic's spectrum of activity, the treatment timing and its duration, the dose and dosing scheme of the particular antimicrobials. Furthermore, antimicrobial therapy should be used with caution, with the aim to prevent development of antimicrobial resistence. Inappropriate choice of antimicrobials in initial empiric therapy results in relapsing infections, surgical intervention and prolongation of hospitalization, and even death rates reflect adequate and timely empiric therapy.

    Antibiotic resistance is a heterogeneous phenomenon. It does not only differ between countries or states, but also between wards of hospitals, where different resistance patterns have been found. To support clinicians in administering empiric antibiotic therapy, we developed software to present information about antibiotic resistance using a mobile concept. A pre-existing infrastructure was deployed as the server component. The systems analyze and aggregate data from laboratory information systems, generating statistical data on antibiotic resistance. The information is presented to the Android client using a Representational State Transfer (REST) interface. Geographical localization is performed using near field communication (NFC) tags. The prototype provides tabulated data concerning antibiotic resistance patterns in the wards of a hospital. Using Android, NFC, and data caching, the usability of the system is estimated to be high. We hypothesize that antibiotic stewardship in hospitals can be supported by this software, thus improving medical monitoring of antibiotic resistance. Future studies in a productive environment are needed to measure the impact of the system on the outcome of patient care.

    Little is known about the nature of effective defense mechanisms in legumes to pathogens of remotely related plant species. Some rust species are among pathogens with broad host range causing dramatic losses in various crop plants. To understand and compare the different host and nonhost resistance (NHR) responses of legume species against rusts, we characterized the reaction of the model legume Medicago truncatula to one appropriate (Uromyces striatus) and two inappropriate (U. viciae-fabae and U. lupinicolus) rusts. We found that similar pre and post-haustorial mechanisms of resistance appear to be operative in M. truncatula against appropriate and inappropriate rust fungus. The appropriate U. striatus germinated better on M. truncatula accessions then the inappropriate U. viciae-fabae and U. lupinicolus, but once germinated, germ tubes of the three rusts had a similar level of success in finding stomata and forming an appressoria over a stoma. However, responses to different inappropriate rust species also showed some specificity, suggesting a combination of non-specific and specific responses underlying this legume NHR to rust fungi. Further genetic and expression analysis studies will contribute to the development of the necessary molecular tools to use the present information on host and NHR mechanisms to breed for broad-spectrum resistance to rust in legume species.

    Full Text Available Background: Each year, around one out of two nursing home (NH residents are hospitalized in France, and about half to the emergency department (ED. These transfers are frequently inappropriate. This paper describes the protocol of the FINE study. The first aim of this study is to identify the factors associated with inappropriate transfers to ED. Methods/design: FINE is a case-control observational study. Sixteen hospitals participate. Inclusion period lasts 7 days per season in each center for a total period of inclusion of one year. All the NH residents admitted in ED during these periods are included. Data are collected in 4 times: before transfer in the NH, at the ED, in hospital wards in case of patient's hospitalization and at the patient's return to NH. The appropriateness of ED transfers (i.e. case versus control NH residents is determined by a multidisciplinary team of experts. Results: Our primary objective is to determine the factors predisposing NH residents to inappropriate transfer to ED. Our secondary objectives are to assess the cost of the transfers to ED; study the evolution of NH residents' functional status and the psychotropic and inappropriate drugs prescription between before and after the transfer; calculate the prevalence of potentially avoidable transfers to ED; and identify the factors predisposing NH residents to potentially avoidable transfer to ED. Discussion: A better understanding of the determinant factors of inappropriate transfers to ED of NH residents may lead to proposals of recommendations of better practice in NH and would allow implementing quality improvement programs in the health organization.

    Full Text Available Prescribing inappropriate pill splitting is not rare in clinical practice. To reduce inappropriate pill splitting, we developed an automatic warning system linked to a computerized physician order entry (CPOE system for special oral formulation drugs in outpatient settings. We examined the impact of the warning system on inappropriate prescribing of pill splitting and assess prescribers' responses to the warnings.Drugs with extended-release or enteric-coated formulations that were not originally intended to be split were recognized as "special oral formulations". A hard-stop system which could examine non-integer doses of drugs with special oral formulations, provide warnings to interrupt inappropriate prescriptions was integrated in CPOE in a medical center since June 2010. We designed an intervention study to compare the inappropriate splitting before and after the implementation of the warning system (baseline period 2010 January to May vs. intervention period 2010 June to 2011 August. During the intervention period, prescription changes in response to a warning were logged and analyzed.A total of 470,611 prescribed drug items with 34 different drugs with special oral formulations were prescribed in the study period. During the 15-month intervention period, 909 warnings for 26 different drugs were triggered among 354,523 prescribed drug items with special oral formulations. The warning rate of inappropriate splitting in the late intervention period was lower than those in baseline period (0.16% vs. 0.61%, incidence rate ratio 0.27, 95% CI 0.23-0.31, P<0.001. In respond to warnings, physicians had to make adjustments, of which the majority was changing to an unsplit pill (72.9%.The interruptive warning system could avoid the prescriptions with inappropriate pill splitting. Accordingly, physicians changed their behavior of prescribing special oral formulations regarding inappropriate pill splitting. We suggest the establishment of such system

    The Multicenter Automatic Defibrillator Implantation Trial-Reduce Inappropriate therapy (MADIT-RIT) trial showed a significant reduction in inappropriate implantable cardioverter defibrillator (ICD) therapy in patients programmed to high-rate cut-off (Arm B) or delayed ventricular tachycardia therapy (Arm C), compared with conventional programming (Arm A). There is limited data on the effect of cardiac resynchronization therapy with a cardioverter defibrillator (CRT-D) on the effect of ICD programming. We aimed to elucidate the effect of CRT-D on ICD programming to reduce inappropriate ICD therapy in patients implanted with CRT-D or an ICD, enrolled in MADIT-RIT. The primary end point of this study was the first inappropriate ICD therapy. Secondary end points were inappropriate anti-tachycardia pacing and inappropriate ICD shock. The study enrolled 742 (49%) patients with an ICD and 757 (51%) patients with a CRT-D. Patients implanted with a CRT-D had 62% lower risk of inappropriate ICD therapy than those with an ICD only (hazard ratio [HR] =0.38, 95% confidence interval: 0.25-0.57; Pprogramming significantly reduced the risk of inappropriate ICD therapy compared with conventional ICD programming in ICD (HR=0.14 [B versus A]; HR=0.21 [C versus A]) and CRT-D patients (HR=0.15 [B versus A]; HR=0.23 [C versus A]; Pprogramming significantly reduces the risk of inappropriate ICD therapy in both ICD and CRT-D patients. http://clinicaltrials.gov; Unique identifier: NCT00947310. © 2016 American Heart Association, Inc.

Methods Consumption data and resistance data were obtained via the Austrian surveillance networks European Antimicrobial Resistance Surveillance System (EARSS and European Surveillance on Antimicrobial Consumption (ESAC. The EARSS collects data on isolates from blood and cerebrospinal fluid obtained predominantly in the hospital setting. The Anatomical Therapeutic Chemical (ATC classification and the Defined Daily Dose (DDD measurement units were assigned to the data. The number of DDDs and packages per 1,000 inhabitants (PID were used to calculate the level of antibiotic consumption. Antibiotic resistance was expressed in resistance rates, i.e., the percentage of resistant isolates compared to all isolates of one bacterial species. Results The overall antibiotic consumption measured in DIDs increased by 10% between 1998 and 2007, whereas PIDs decreased by 3%. The consumption of substances within the drug utilization 90% segment (measured in PID increased for ciprofloxacin (+118.9, clindamycin (+76.3, amoxicillin/clavulanic acid (+61.9%, cefpodoxime (+31.6, azithromycin (+24.7; and decreased for erythromycin (-79.5%, trimethoprim (-56,1%, norfloxacin (-48.8%, doxycycline (-44.6, cefaclor (-35.1%, penicillin (-34.0%, amoxicillin (-22.5, minocycline (-21.9% and clarithromycin (-9.9%.

    Full Text Available ABSTRACTMonitoring programs have traditionally monitored legacy contaminants but are shifting focus to Contaminants of Emerging Concern (CECs. CECs present many challenges for monitoring and assessment, because measurement methods don't always exist nor have toxicological studies been fully conducted to place results in proper context. Also some CECs affect metabolic pathways to produce adverse outcomes that are not assessed through traditional toxicological evaluations. Antibiotics are CECs that pose significant environmental risks including development of both toxic effects at high doses and antibiotic resistance at doses well below the Minimum Inhibitory Concentration (MIC which kill bacteria and have been found in nearly half of all sites monitored in the US. Antimicrobial resistance has generally been attributed to the use of antibiotics in medicine for humans and livestock as well as aquaculture operations. The objective of this study was to assess the extent and magnitude of antibiotics in the environment and estimate their potential hazards in the environment. Antibiotics concentrations were measured in a number of monitoring studies which included Waste Water Treatment Plants (WWTP effluent, surface waters, sediments and biota. A number of studies reported levels of Antibiotic Resistant Microbes (ARM in surface waters and some studies found specific ARM genes (e.g. the blaM-1 gene in E. coli which may pose additional environmental risk. High levels of this gene were found to survive WWTP disinfection and accumulated in sediment at levels 100-1000 times higher than in the sewerage effluent, posing potential risks for gene transfer to other bacteria.in aquatic and marine ecosystems. Antibiotic risk assessment approaches were developed based on the use of MICs and MIC Ratios [High (Antibiotic Resistant/Low (Antibiotic Sensitive MIC] for each antibiotic indicating the range of bacterial adaptability to each antibiotic to help define the No

    Full Text Available Antibiotics are chemotherapeutic agents, which have been a very powerful tool in the clinical management of bacterial diseases since the 1940s. However, benefits offered by these magic bullets have been substantially lost in subsequent days following the widespread emergence and dissemination of antibiotic resistant strains. While it is obvious that excessive and imprudent use of antibiotics significantly contributes to the emergence of resistant strains, antibiotic-resistance is also observed in natural bacteria of remote places unlikely to be impacted by human intervention. Both antibiotic biosynthetic genes and resistance-conferring genes have been known to evolve billions of years ago, long before clinical use of antibiotics. Hence it appears that antibiotics and antibiotics resistance determinants have some other roles in nature, which often elude our attention because of overemphasis on the therapeutic importance of antibiotics and the crisis imposed by the antibiotic-resistance in pathogens. In the natural milieu, antibiotics are often found to be present in subinhibitory concentrations acting as signalling molecules supporting quorum sensing and biofilm formation. They also play an important role in the production of virulence factors and influence host-parasite interactions (e.g., phagocytosis, adherence to the target cell and so on. The evolutionary and ecological aspects of antibiotics and antibiotic-resistance in the naturally occurring microbial community are little understood. Therefore, the actual role of antibiotics in nature warrants in-depth investigations. Studies on such an intriguing behaviour of the microorganisms promise insight into the intricacies of the microbial physiology and are likely to provide some lead in controlling the emergence and subsequent dissemination of antibiotic resistance. This article highlights some of the recent findings on the role of antibiotics and genes that confer resistance to antibiotics in

    The aim of the study was to compare the antibiotic treatment actually received by elderly, hospitalised patients with urinary tract infection (UTI) with 'optimal' therapy (as gauged by compliance with antibiotic policy, infecting organism, sensitivity data, patient renal function and cost). UTI was more common in females and in catheterised patients and E.Coli was the commonest pathogen. Trimethoprim and co-amoxiclav were the drugs used most frequently for either empirical or sensitivity data-based treatment. In 96% of infections a drug with appropriate action was administered. Often, however, treatment could have been optimised by substituting a cheaper suitable antibiotic, by standardising duration of therapy and ensuring that doses were adjusted for renal impairment. Savings from the use of 'optimal' therapy were estimated at 17%. There is clearly considerable scope for positive input from the clinical pharmacist in this area.

    Escherichia coli is a common cause of urinary tract infections (UTI). Reviews of antibiotic resistance of this organism can inform choice of empiric treatment of UTI and other infections and strategies for combating antimicrobial resistance. We reviewed laboratory and hospital pharmacy records to assess trends in non-susceptibility rates and the effect of antimicrobial stewardship interventions. A retrospective observational study of isolates of E. coli from MSU samples at a Dublin teaching hospital from inpatients and community, obtained from January 2005 to December 2014. Susceptibility to a panel of antibiotics was determined using the disc diffusion method, as well as extended-spectrum beta-lactamase (ESBL) production status. Trends in resistance were plotted graphically and analysed in a descriptive manner. Except for nitrofurantoin and gentamicin, non-susceptibility increased for all antimicrobials tested. Co-amoxiclav non-susceptibility reached 48% in hospital and 32.6% in the community by 2014. Piperacillin-tazobactam non-susceptibility increased from 6.8 to 23.8% in hospital and from coli isolates from community MSU samples have high rates of non-susceptibility to trimethoprim and co-amoxiclav. Nitrofurantoin remains the best empiric therapy for cystitis. Increasing non-susceptibility to co-amoxiclav and piperacillin-tazobactam in hospital isolates is concerning. Ciprofloxacin non-susceptibility is increasing faster in the community than in hospital. A sharp reduction in hospital fluoroquinolone consumption did not result in a significant reduction in ciprofloxacin non-susceptibility of hospital E. coli isolates.

    Knowledge of local antimicrobial resistance patterns is essential for evidence-based empirical antibiotic prescribing, and a cutoff point of 20% has been suggested as the level of resistance at which an agent should no longer be used empirically. We sought to identify the changing incidence of causative uropathogens over an 11-year period. We also examined the trends in antibiotic resistance encountered in both the pooled urine samples and those where the causative organism was Escherichia coli. A retrospective analysis of the antimicrobial resistance within the positive community urine isolates over the 11-year period, 1999 to 2009, in a single Dublin teaching hospital was performed. In total 38,530 positive urine samples processed at our laboratory originated in the community of which 23,838 (56.7%) had E. coli as the infecting organism. The prevalence of E. coli has been increasing in recent years in community UTIs with 70.4% of UTIs in the community caused by E.coli in 2009. Ampicillin and trimethoprim were the least-active agents against E. coli with mean 11-year resistance rates of 60.8 and 31.5%, respectively. Significant trends of increasing resistance over the 11-year period were identified for trimethoprim, co-amoxyclav, cefuroxime and gentamicin. Ciprofloxacin remains a reasonable empirical antibiotic choice in this community with an 11-year resistance rate of 10.6%. Higher antibiotic resistance rates were identified in the male population and in children. Resistance rates to commonly prescribed antibiotics are increasing significantly. This data will enable evidence-based empirical prescribing which will ensure more effective treatment and lessen the emergence of resistant uropathogens in the community.

  11. Selection of antibiotic resistance at very low antibiotic concentrations.

    Human use of antibiotics has driven the selective enrichment of pathogenic bacteria resistant to clinically used drugs. Traditionally, the selection of resistance has been considered to occur mainly at high, therapeutic levels of antibiotics, but we are now beginning to understand better the importance of selection of resistance at low levels of antibiotics. The concentration of an antibiotic varies in different body compartments during treatment, and low concentrations of antibiotics are found in sewage water, soils, and many water environments due to natural production and contamination from human activities. Selection of resistance at non-lethal antibiotic concentrations (below the wild-type minimum inhibitory concentration) occurs due to differences in growth rate at the particular antibiotic concentration between cells with different tolerance levels to the antibiotic. The minimum selective concentration for a particular antibiotic is reached when its reducing effect on growth of the susceptible strain balances the reducing effect (fitness cost) of the resistance determinant in the resistant strain. Recent studies have shown that resistant bacteria can be selected at concentrations several hundred-fold below the lethal concentrations for susceptible cells. Resistant mutants selected at low antibiotic concentrations are generally more fit than those selected at high concentrations but can still be highly resistant. The characteristics of selection at low antibiotic concentrations, the potential clinical problems of this mode of selection, and potential solutions will be discussed.

    Inappropriate antibiotic prescription and consequent antibacterial resistance is a major threat to healthcare. To evaluate the efficacy of a multifaceted intervention in reducing early career general practitioners' (GPs') antibiotic prescribing for upper respiratory tract infections (URTIs) and acute bronchitis/bronchiolitis. A pragmatic non-randomized trial employing a non-equivalent control group design nested within an existing cohort study of GP registrars' (trainees') clinical practice. The intervention included access to online modules (covering the rationale of current clinical guidelines recommending non-prescription of antibiotics for URTI and bronchitis/bronchiolitis, and communication skills in management of acute bronchitis) followed by a face-to-face educational session. The intervention was delivered to registrars (and their supervisors) in two of Australia's seventeen regional GP training providers (RTPs). Three other RTPs were the control group. Outcomes were proportion of registrars' URTI consultations and bronchitis/bronchiolitis consultations prescribed antibiotics. Intention-to-treat analyses employed logistic regression within a Generalised Estimating Equation framework, adjusted for relevant independent variables. The predictors of interest were time; treatment group; and an interaction term for time-by-treatment group. The P value associated with an interaction term determined statistically significant differences in antibiotic prescribing. Analyses include data of 217 intervention RTPs' and 311 control RTPs' registrars. There was no significant reduction in antibiotic prescribing for URTIs. For bronchitis/bronchiolitis, a significant reduction (interaction P value = 0.024) remained true for analysis adjusted for independent variables (P value = 0.040). The adjusted absolute reduction in prescribing was 15.8% (95% CI: 4.2%-27.5%). A multifaceted intervention reduced antibiotic prescribing for bronchitis/bronchiolitis but not URTIs. © The

    The prevalence and predisposing factors were determined for inappropriate urinary catheterization (UC) among inpatients in medical wards. A cross-sectional study was conducted including all patients aged ≥ 18 years admitted to medical wards in a 1300-bed tertiary-care centre, and who had a urinary catheter in place on the day of the survey. Of 380 patients observed, 46 (12.1%) had a urinary catheter in place. Twelve of them (26.1%) were inappropriately catheterized. The most common indication for inappropriate UC was urine output monitoring in a cooperative, non-critically ill patient. Inappropriateness was associated with increased age, poor functional status, urinary incontinence, dementia, and admission from a long-term care facility. Further educational efforts should be focused on improving catheterization prescribing practices by physicians. Copyright © 2012 Elsevier España, S.L. All rights reserved.

    Escherichia coli is a common cause of bloodstream infections (BSIs) in infants and is associated with high mortality and morbidity among survivors. The clinical significance of antibiotic resistance and timing of appropriate antimicrobial therapy in this population is poorly understood. We identified all infants with E. coli BSIs discharged from 77 neonatal intensive care units managed by the Pediatrix Medical Group in 2012. We used multivariable logistic regression to evaluate the association between 30-day mortality and ampicillin-resistant E. coli BSI, as well as the number of active empiric antimicrobial agents administered, controlling for gestational age, small-for-gestational age status, early-onset versus late-onset BSI, oxygen requirement, ventilator support and inotropic support on the day of the first positive blood culture. We identified 258 episodes of E. coli BSI, including 123 (48%) ampicillin-resistant isolates. Unadjusted 30-day mortality did not significantly differ between infants with ampicillin-resistant versus ampicillin-susceptible E. coli BSI [11 of 123 (9%) vs. 7 of 135 (5%); P = 0.33; adjusted odds ratio = 1.37 (95% confidence interval: 0.39, 4.77)]. Among ampicillin-resistant E. coli BSIs, 30-day mortality was not significantly lower for infants treated with at least one empiric antimicrobial active against ampicillin-resistant E. coli versus infants receiving no active empiric agent [adjusted odds ratio = 1.50 (0.07, 33.6)]. In this population of infants with E. coli BSI, ampicillin resistance was not associated with significantly increased mortality. Among the subset of infants with ampicillin-resistant E. coli, appropriate empirical antibiotic therapy was not associated with lower mortality.

    Streptococcus constellatus and Streptococcus intermedius in subgingival dental plaque biofilms may contribute to forms of periodontitis that resist treatment with conventional mechanical root debridement/surgical procedures and may additionally participate in some extraoral infections. Because systemic antibiotics are often used in these clinical situations, and little is known of the antibiotic susceptibility of subgingival isolates of these two bacterial species, this study determined the in vitro susceptibility to six antibiotics of fresh S. constellatus and S. intermedius clinical isolates from human periodontitis lesions. A total of 33 S. constellatus and 17 S. intermedius subgingival strains, each recovered from separate patients with severe chronic periodontitis (n = 50) before treatment, were subjected to antibiotic gradient strip susceptibility testing with amoxicillin, azithromycin, clindamycin, ciprofloxacin, and doxycycline on blood-supplemented Mueller-Hinton agar and to the inhibitory effects of metronidazole at 16 mg/L in an enriched Brucella blood agar dilution assay. Clinical and Laboratory Standards Institute and European Committee on Antimicrobial Susceptibility Testing interpretative standards were used to assess the results. Clindamycin was the most active antibiotic against S. constellatus (minimum inhibitory concentration at 90% [MIC90] 0.25 mg/L), and amoxicillin was most active against S. intermedius (MIC90 0.125 mg/L). A total of 30% of the S. constellatus and S. intermedius clinical isolates were resistant in vitro to doxycycline, 98% were only intermediate in susceptibility to ciprofloxacin, and 90% were resistant to metronidazole at 16 mg/L. Subgingival S. constellatus and S. intermedius exhibited variable antibiotic susceptibility profiles, potentially complicating empirical selection of periodontitis antibiotic therapy in patients who are species positive.

    Full Text Available Objective: To determine the community associated urinary tract infection (UTI causing uropathogen's prevalence, antibiotic resistance pattern and the risk factors predisposing infection in Indian rural settings. Methods: A pilot study was conducted between January and December 201 0 among out patients attending rural teaching medical college hospital at Tamilnadu, India. The demographic details, culture, common antibiotic Kirby-Bauer disc diffusion assay susceptibility profiles of the isolates and the resistance analysis by WHONET 5.6 software were performed. Results: During this surveillance study, a total number of 1 359 urinary samples were collected, among which 309 (22.78% gave positive culture. The common uropathogens encountered were Escherichia coli (66.02%, Staphylococcus sp. (12.62%, Klebsiella sp. (5.83%, Streptococcus sp. (5.1 8%, Enterococcus sp. (2.59% and Proteus sp., (2.26%. Antibiotic resistance analysis revealed the multiple drug resistance nature of the isolates to the commonly used antibiotics. It is also found that both genders at the specific age group of 40-50 were more prone to infection and seasonal variations also play an important role in their establishment. Conclusions: The obtained results suggest that antibiotic selection for empirical treatment should be based on individual drug-sensitive test results. There is also an urgent need to develop a new combination of chemotherapeutic agents and awareness on antibiotic use for the effective UTI management in rural settings.

    Full Text Available Antibiotic contamination in agroecosystems may cause serious problems, such as the proliferation of various antibiotic resistant bacteria and the spreading of antibiotic resistance genes (ARGs in the environment or even to human beings. However, it is unclear whether environmental antibiotics, antibiotic resistant bacteria, and ARGs can directly enter into, or occur in, the endophytic systems of plants exposed to pollutants. In this study, a hydroponic experiment exposing pakchoi (Brassica chinensis L. to tetracycline, cephalexin, and sulfamethoxazole at 50% minimum inhibitory concentration (MIC levels and MIC levels, respectively, was conducted to explore plant growth, antibiotic uptake, and the development of antibiotic resistance in endophytic systems. The three antibiotics promoted pakchoi growth at 50% MIC values. Target antibiotics at concentrations ranging from 6.9 to 48.1 µg·kg−1 were detected in the treated vegetables. Additionally, the rates of antibiotic-resistant endophytic bacteria to total cultivable endophytic bacteria significantly increased as the antibiotics accumulated in the plants. The detection and quantification of ARGs indicated that four types, tetX, blaCTX-M, and sul1 and sul2, which correspond to tetracycline, cephalexin, and sulfamethoxazole resistance, respectively, were present in the pakchoi endophytic system and increased with the antibiotic concentrations. The results highlight a potential risk of the development and spread of antibiotic resistance in vegetable endophytic systems.

    Infections are the most common complication in patients receiving treatment for cancer with neutropenia being the primary risk factor for the development of an infection. In the neutropenic patient, bacteremia remains a significant cause of mortality. Although the literature reports that prompt empiric antibiotic therapy to prevent death caused by virulent organisms is the standard of care, the literature fails to identify what prompt antibiotic administration means. Door/fever-to-patient antibiotic delivery was evaluated as a quality control measure in a new children's hospital. Initially, door/fever-to-patient time was significantly delayed. Collaboration between pharmacy, hospital bed control, medical, and nursing staff resulted in many changes in practice by all groups. As a result, the goal for prompt antibiotic delivery of thirty minutes or less is now achievable.

    Antibiotic resistance is a global and increasing problem that is not counterbalanced by the development of new therapeutic agents. The prevalence of antibiotic resistance is especially high in intensive care units with frequently reported outbreaks of multidrug-resistant organisms. In addition to classical infection prevention protocols and surveillance programs, counterintuitive interventions, such as selective decontamination with antibiotics and antibiotic rotation have been applied and investigated to control the emergence of antibiotic resistance. This review provides an overview of selective oropharyngeal and digestive tract decontamination, decolonization of methicillin-resistant Staphylococcus aureus and antibiotic rotation as strategies to modulate antibiotic resistance in the intensive care unit.

    Inappropriate prescribing in older people is a common condition associated with significant morbidity, mortality, and financial costs. Medication use increases with age, and this, in conjunction with an increasing disease burden, is associated with adverse drug reactions. This review outlines why older people are more likely to develop adverse drug reactions and how common the problem is. The use of different tools to identify and measure the problem is reviewed. Common syndromes seen in older adults (eg, falling, cognitive impairment, sleep disturbance) are considered, and recent evidence in relation to medication use for these conditions is reviewed. Finally, we present a brief summary of significant developments in the recent literature for those caring for older people.

    Inappropriate use of antibiotics is contributing to the increasing rates of antimicrobial resistance. Several Danish guidelines on antibiotic prescribing for acute respiratory tract infections in general practice have been issued to promote rational prescribing of antibiotics, however it is unclear if these recommendations are followed. We aimed to characterise the pattern of antibiotic prescriptions for patients diagnosed with acute respiratory tract infections, by means of electronic prescriptions, labeled with clinical indications, from Danish general practice. Acute respiratory tract infections accounted for 456,532 antibiotic prescriptions issued between July 2012 and June 2013. Pneumonia was the most common indication with 178,354 prescriptions (39%), followed by acute tonsillitis (21%) and acute otitis media (19%). In total, penicillin V accounted for 58% of all prescriptions, followed by macrolides (18%) and amoxicillin (15%). The use of second-line agents increased with age for all indications, and comprised more than 40% of the prescriptions in patients aged >75 years. Women were more often prescribed antibiotics regardless of clinical indication. This is the first Danish study to characterise antibiotic prescription patterns for acute respiratory tract infections by data linkage of clinical indications. The findings confirm that penicillin V is the most commonly prescribed antibiotic agent for treatment of patients with an acute respiratory tract infection in Danish general practice. However, second-line agents like macrolides and amoxicillin with or without clavulanic acid are overused. Strategies to improve the quality of antibiotic prescribing especially for pneumonia, acute otitis media and acute rhinosinusitis are warranted. TRACKING THE OVERUSE OF ANTIBIOTICS: Better adherence to guidelines for prescribing antibiotics for different respiratory tract infections are warranted in Danish general practice.

    INTRODUCTION: Adverse drug events (ADEs) are associated with inappropriate prescribing (IP) and result in increased morbidity, mortality and resource utilisation. We used Beers\\' Criteria to determine the three-month prevalence of IP in a non-selected community-dwelling population of acutely ill older people requiring hospitalisation. METHODS: A prospective, observational study of 597 consecutive acute admissions was performed. Diagnoses and concurrent medications were recorded before hospital physician intervention, and Beers\\' Criteria applied. RESULTS: Mean patient age (SD) was 77 (7) years. Median number of medications was 5, range 0-13. IP occurred in 32% of patients (n = 191), with 24%, 6% and 2% taking 1, 2 and 3 inappropriate medications respectively. Patients taking >5 medications were 3.3 times more likely to receive an inappropriate medication than those taking < or =5 medications (OR 3.34: 95%, CI 2.37-4.79; P<0.001). Forty-nine per cent of patients with inappropriate prescriptions were admitted with adverse effects of the inappropriate medications. Sixteen per cent of all admissions were associated with such adverse effects. CONCLUSION: IP is highly prevalent in acutely ill older patients and is associated with polypharmacy and hospitalisation. However, Beers\\' Criteria cannot be used as a gold standard as they do not comprehensively address all aspects of IP in older people.

The aim of this study was to evaluate inappropriate use of IUCs and their complications among patients in Tehran, Iran. Two hundred and six consecutive patients hospitalized in the intensive care unit (ICU as well as medical and surgical wards at the Shahid Mohammadi Hospital in Bandarabbas from September 1 to 30, 2005 and in whom IUCs were used, were studied. Data collected included age of the patients, diagnoses, reason for use of IUC and the complications related to it. Overall, 164 patients (79.6% had IUCs used appropriately while 42 of them (20.6% were catheterized unjustifiably. Inappropriate use of IUCs in the ICU, medical and surgical wards was reported in 12 (18.5%, 16 (19.0% and 14 patients (24.6%, respectively. The most common complication of IUCs was urinary tract infection, which occurred in 91 patients (44.2% and hematuria, which was seen in 3.9% of the patients. Our study suggests that inappropriate use of IUCs is prevalent, particularly in the surgical wards, and the most common complication observed was catheter-associated urinary tract infection.

    Antimicrobial resistance is a major public health threat driven by inappropriate antibiotic use, mainly in general practice and for respiratory tract infections. In Belgium, the quality of general practitioners' (GPs) antibiotic prescribing is low. To improve antibiotic use, we need a better understanding of this quality problem and corresponding interventions. A general practitioners cooperative (GPC) for out-of-hours (OOH) care presents a unique opportunity to reach a large group of GPs and work on quality improvement. Participatory action research (PAR) is a bottom-up approach that focuses on implementing change into daily practice and has the potential to empower practitioners to produce their own solutions to optimise their antibiotic prescribing. This PAR study to improve antibiotic prescribing quality in OOH care uses a mixed methods approach. In a first exploratory phase, we will develop a partnership with a GPC and map the existing barriers and opportunities. In a second phase, we will focus on facilitating change and implementing interventions through PDSA (Plan-Do-Study-Act) cycles. In a third phase, antibiotic prescribing quality outside and antibiotic use during office hours will be evaluated. Equally important are the process evaluation and theory building on improving antibiotic prescribing. The study protocol was approved by the Ethics Committee of the Antwerp University Hospital/University of Antwerp. PAR unfolds in response to the needs and issues of the stakeholders, therefore new ethics approval will be obtained at each new stage of the research. Interventions to improve antibiotic prescribing are needed now more than ever and outcomes will be highly relevant for GPCs, GPs in daily practice, national policymakers and the international scientific community.

    questionnaire, with significant differences between institutions. Students who used antibiotic prescribing guidelines and found their education more useful scored higher on knowledge questionnaires. Conclusion. There are low levels of confidence with regard to antibiotic prescribing among final-year medical students in SA, and most students would like more education in this area. Perceptions that ABR is less of a problem in their local setting may contribute to inappropriate prescribing behaviours. Differences exist between medical schools in knowledge about antibiotic use, with suboptimal scores across institutions. The introduction and use of antibiotic prescribing guidelines and greater contact with specialists in antibiotic prescribing may improve prescribing behaviours.

    Medication errors such as potential inappropriate prescriptions would induce serious adverse drug events to patients. Information technology has the ability to prevent medication errors; however, the pharmacology of traditional Chinese medicine (TCM) is not as clear as in western medicine. The aim of this study was to apply the appropriateness of prescription (AOP) model to identify potential inappropriate TCM prescriptions. We used the association rule of mining techniques to analyze 14.5 million prescriptions from the Taiwan National Health Insurance Research Database. The disease and TCM (DTCM) and traditional Chinese medicine-traditional Chinese medicine (TCMM) associations are computed by their co-occurrence, and the associations' strength was measured as Q-values, which often referred to as interestingness or life values. By considering the number of Q-values, the AOP model was applied to identify the inappropriate prescriptions. Afterwards, three traditional Chinese physicians evaluated 1920 prescriptions and validated the detected outcomes from the AOP model. Out of 1920 prescriptions, 97.1% of positive predictive value and 19.5% of negative predictive value were shown by the system as compared with those by experts. The sensitivity analysis indicated that the negative predictive value could improve up to 27.5% when the model's threshold changed to 0.4. We successfully applied the AOP model to automatically identify potential inappropriate TCM prescriptions. This model could be a potential TCM clinical decision support system in order to improve drug safety and quality of care. Copyright © 2016 John Wiley & Sons, Ltd.

Descriptive and analytic statistics were applied. Results: Sample with equal sex distribution constituted of 5,752 cases: adults (15 years =61% and pediatrics (<15 years =39%. Around 55% complained of respiratory tract infections, 25% urinary tract infections (UTIs, and 20% others. Broad-spectrum coverage ATBs were prescribed for 76% of the cases. Before the prescription, 82% of pediatrics had their weight taken, while 18% had their weight estimated. Allergy checking was done in 8% only. Prevalence of inappropriate ATB prescriptions with at least one type of error was 46.2% (pediatrics =58% and adults =39%. Errors were in ATB selection (2%, dosage (22%, frequency (4%, and duration (29%. Dosage and duration errors were significantly predominant among pediatrics (P<0.001 and P<0.0001, respectively. Selection error was higher among adults (P=0.001. Age stratification and binary logistic regression were applied. Significant predictors of inappropriate prescriptions were associated with: 1 cephalosporin prescriptions (adults: P<0.001, adjusted odds ratio [adj OR] =3.31 (pediatrics: P<0.001, adj OR

    Objective: Antibiotics are widely used in the treatment of infections and for empirical treatment purposes. Despite this common consumption of antibiotics, it is difficult to state that antibiotics are chosen and used consciously. This study was planned to determine the prevalence of prescribing antibiotics in Turkey. Methodology: This cross-sectional study was conducted in November 2003. The study was carried out in a total of 46 primary care health centers of the following cities; Central Anatolian, Western Anatolian, Eastern Anatolian regions. Results: Two hundred sixty seven physicians participated in the study, 38.9% (104) of which were women and 61.1% (163) were men. The proportion of antibiotic prescription was by 22,6%, and the most frequently chosen antibiotics were 15.6% (3301) Amoxycilline + Clavulanic acid (Amox/Clav), 15.1% (3184) Ampicilline + Sulbactam 12.84% (2711), respectively. When prescriptions with antibiotics were evaluated according to diagnosis, the most frequent diagnoses were found to be as follows: 53.3% (11430) Acute Upper Respiratory Infections, 16.4% (3516) Urinary Tract Infections. Conclusions: The findings of the study suggest that primary health care physicians most often prescribe for acute respiratory tract infections, and prescribe Amoxycilline + Clavunic the most. It may be argued that more extensive studies are needed in this field. (author)

    Full Text Available Background. Proton pump inhibitors (PPIs are currently the most effective agents for acid-related disorders. However, studies show that 25–75% of patients receiving intravenous PPIs had no appropriate justification, indicating high rates of inappropriate prescribing.Objective. To examine the appropriate use of intravenous PPIs in accordance with guidelines and the efficacy of a prescribing awareness intervention at an Asian teaching institution.Setting. Prospective audit in a tertiary hospital in Malaysia.Method. Every 4th intravenous PPI prescription received in the pharmacy was screened against hospital guidelines. Interventions for incorrect indication/dose/duration were performed. Patients’ demographic data, medical history and the use of intravenous PPI were collected. Included were all adult inpatients prescribed intravenous PPI.Main Outcome Measure. Proportion of appropriate IV PPI prescriptions.Results. Data for 106 patients were collected. Most patients were male [65(61.3%], Chinese [50(47.2%], with mean age ± SD = 60.3 ± 18.0 years. Most intravenous PPI prescriptions were initiated by junior doctors from the surgical [47(44.3%] and medical [42(39.6%] departments. Only 50/106(47.2% patients had upper gastrointestinal endoscopy/surgery performed to verify the source of bleeding. Unexplained abdominal pain [81(76.4%] was the main driver for prescribing intravenous PPIs empirically, out of which 73(68.9% were for suspected upper gastrointestinal bleed. Overall, intravenous PPI was found to be inappropriately prescribed in 56(52.8% patients for indication, dose or duration. Interventions on the use of intravenous PPI were most effective when performed by senior doctors (100%, followed by clinical pharmacists (50%, and inpatient pharmacists (37.5%, p = 0.027.Conclusion. Inappropriate intravenous PPI usage is still prevalent despite the enforcement of hospital guidelines. The promotion of prescribing awareness and evidence

Skin, blood, and urine cultures were taken. Oral quinolone prophylaxis was started in patients with neutropenia without fever. Empiric starting therapy consisted of amikacin in combination with cefepime.Results: A total of 3624 bacteria were isolated. The most common pathogens were coagulase-negative Staphylococci (46%, followed by Escherichia coli (25%, Enterobacteriaceae (15.6%, Staphylococcus aureus (7.2%, and Pseudomonas aeruginosa (3.8%. The balance between Gram-positive and Gram-negative bacteria remained stable, with a majority of Gram-positive bacteria. A shift from oxacillin-sensitive to oxacillin-resistant coagulase-negative Staphylococci was observed. Regarding susceptibility patterns, no vancomycin resistance was detected in coagulase-negative Staphylococci or in S. aureus. The E. coli susceptibility rates remained stable. However, 66% of bloodstream infections were ciprofloxacin-resistant. A reduced susceptibility of P. aeruginosa strains to meropenem was noticed.Conclusions: Improvement in antibiotic susceptibility of inducible Enterobacteriaceae ­following a switch of empiric antibiotic therapy was maintained 15 years

    The nonhormonal medical treatment can be divided into empirical, when the cause has not been identified, and nonempirical, if the pathogenic mechanism causing male infertility can be solved or ameliorated. The empirical nonhormonal medical treatment has been proposed for patients with idiopathic or noncurable oligoasthenoteratozoospermia and for normozoospermic infertile patients. Anti-inflammatory, fibrinolytic, and antioxidant compounds, oligo elements, and vitamin supplementation may be prescribed. Infection, inflammation, and/or increased oxidative stress often require a specific treatment with antibiotics, anti-inflammatory drugs, and/or antioxidants. Combined therapies can contribute to improve sperm quality.

    was 79.85). E. coli and S. aureus were the predominant pathogens in the study and many were resistant to the commonly prescribed antibiotics and so leave the clinicians with only few alternative drugs for UTIs treatment. Routine surveillance and monitoring studies need to be constantly conducted to update clinicians on the prevalent pathogens and the rational and empirical treatment of UTIs. Aggressive and consistent health education using every possible media is also recommended to combat the menace of drug resistance occasioned by inappropriate antibiotic use.

    Objective was to determine the resistance of antibiotics for complicated urinary tract infection (UTI), including urinary tract anomaly (UTA), for empirical antibiotic therapy of complicated UTI. Four hundred and twenty two urine isolates were obtained from 113 patients with recurrent UTI, who used prophylactic antibiotics between February 1999 and November 2004 in the Eskisehir Osmangazi University, Eskisehir, Turkey. Reflux was found to be most important predisposing factor for recurrent UTI (31.9%). Renal scar was detected more in patients with UTA than without UTA (59.2% versus 12.4%, p<0.05). Gram-negative organisms were dominant in patients with and without UTA (91.5% and 79.2%). Enterococci and Candida spp. were more prevalent in children with UTA than without UTA (p<0.001). Isolates were significantly more resistant to ampicillin, trimethoprim-sulfamethoxazole, amikacin, co-amoxiclav, ticarcillin-clvalanate and piperacillin-tazobactam in patients with UTA than without UTA. We found low resistance to ciprofloxacin and nitrofurantoin in UTI with and without UTA. Enterococci spp. was highly resistance to ampicillin and amikacin in patients with UTA. Aztreonam, meropenem and ciprofloxacin seemed to be the best choice for treatment of UTI with UTA due to Escherichia coli and Klebsiella spp. Nitrofurantoin and nalidixic acid may be first choice antibiotics for prophylaxis in UTI with and without UTA. The UTI with UTA caused by Enterococci spp. might not benefit from a combination of amikacin and ampicillin, it could be treated with glycopeptides. (author)

  2. Inappropriate prescribing in the older population: need for new criteria.

    LENUS (Irish Health Repository)

    2012-02-03

    Inappropriate prescribing (IP) is a common and serious global healthcare problem in elderly people, leading to increased risk of adverse drug reactions (ADRs), polypharmacy being the main risk factor for both IP and ADRs. IP in older people is highly prevalent but preventable; hence screening tools for IP have been devised, principally Beers\\' Criteria and the Inappropriate Prescribing in the Elderly Tool (IPET). Although Beers\\' Criteria have become the most widely cited IP criteria in the literature, nevertheless, they have serious deficiencies, including several drugs that are rarely prescribed nowadays, a lack of structure in the presentation of the criteria and omission of several important and common IP instances. New, more up-to-date, systems-based and easily applicable criteria are needed that can be applied in the routine clinical setting.

    Considerable controversy persists regarding the use of human antibiotics to promote growth in animals raised for food. The authors examined the economic effect of removing antibiotics used for growth promotion in commercial broiler chickens. The authors utilized data published by the Perdue company, the fourth largest poultry producer in the United States, in which a non-randomized controlled trial of growth-promoting antibiotic (GPA) use was conducted with seven million broiler chickens to evaluate the impact of removing GPAs on production. Positive production changes were associated with GPA use, but were insufficient to offset the cost of the antibiotics. The net effect of using GPAs was a lost value of 0.0093 dollars per chicken (about 0.45% of total cost). Based upon these data, the authors found no basis for the claim that the use of GPAs lowers the cost of production. Note that this study does not include veterinary cost changes or changes in performance variability associated with the removal of GPAs. This economic analysis is the first study to the authors' knowledge utilizing large-scale empirical data collected by U.S. industry, in which it is demonstrated that the use of GPAs in poultry production is associated with economic losses to the producers. These data are of considerable importance in the ongoing national debate concerning the continued use of antibiotics for growth promotion of food animals. Based on the industry study and the resulting economic impact, the use of GPAs in U.S. poultry production should be reconsidered.

    2014-01-01

    Identifying social gaffes is important for maintaining relationships. Older adults are less able than young to discriminate between socially appropriate and inappropriate behavior in video clips. One open question is how these social appropriateness ratings relate to potential age differences in the perception of what is actually funny or not. In the present study, young, middle-aged, and older adults were equally able to discriminate between appropriate and inappropriate social behavior in a diverse set of clips relevant to both age groups. However, young and middle-aged adults rated the gaffe clips as funnier than control clips and young adults smiled more during the inappropriate clips than the control clips. Older adults did not show this pattern, suggesting that they did not find the inappropriate clips funny. Additionally, young adults endorsed a more aggressive humor style than middle-aged and older adults and aggressive humor style endorsement mediated age differences in social appropriateness ratings. Results are discussed in terms of possible mechanisms such as cohort differences in humor and developmental prioritization of certain humor styles, as well as the importance of investigating age differences in both abilities and preferences.

    Full Text Available Background. The need for healthcare in paediatric patients is often due to respiratory diseases, acute diarrhoea and viral fever, which suggests a limited need for the use of antibiotics. Objectives. To identify the determinants of antibiotic prescription in hospitalised paediatric patients in Mozambique. Methods. A cross-sectional study was conducted between January and June 2015. A total of 454 medical prescriptions and clinical records of children aged 0 - 14 years from Hospital Central de Maputo (HCM and Hospital Geral de Mavalane (HGM were analysed. Results. Antibiotics were used in 97.6% of the patients, with no significant differences (p>0.05 in the prescription rates of the hospitals. The most commonly used antibiotics were beta-lactams (57.3%, aminoglycosides (28.3% and co-trimoxazole (9.4%. Antibiotics were prescribed in all cases of bronchopneumonia, fever, sepsis and acute gastroenteritis. For malaria and undefined diagnoses, antibiotics were prescribed 97.8% and 99.3% of cases, respectively. It was clear that most severe clinical conditions (odds ratio (OR 9.06; 1.13 - 12.14 and age <5 years (OR 5.47;1.54 - 7.60 were treated with antibiotics. Conclusion. The prescription of antibiotics for paediatric patients at both HCM and HGM was largely influenced by patients’ clinical condition and age. It showed that physicians used an empirical approach, in the absence of laboratory tests, often leading to unnecessary antibiotic treatments with negative causative effects. Physicians should be encouraged to use an evidence-based approach for managing the cases correctly.

    Pitch processing is a critical ability on which humans' tonal musical experience depends, and which is also of paramount importance for decoding prosody in speech. Congenital amusia refers to deficits in the ability to properly process musical pitch, and recent evidence has suggested that this musical pitch disorder may impact upon the processing of speech sounds. Here we present the first electrophysiological evidence demonstrating that individuals with amusia who speak Mandarin Chinese are impaired in classifying prosody as appropriate or inappropriate during a speech comprehension task. When presented with inappropriate prosody stimuli, control participants elicited a larger P600 and smaller N100 relative to the appropriate condition. In contrast, amusics did not show significant differences between the appropriate and inappropriate conditions in either the N100 or the P600 component. This provides further evidence that the pitch perception deficits associated with amusia may also affect intonation processing during speech comprehension in those who speak a tonal language such as Mandarin, and suggests music and language share some cognitive and neural resources.

    Autism spectrum disorder (ASD) is a neurodevelopmental disorder impairing social skills and communication. Adolescents with ASD have sexual needs, but may not understand their physical and emotional development resulting in inappropriate sexual behaviour. The aim of this review is to describe the type of inappropriate behaviour that presents in these adolescents, explain why such behaviours occur, suggest what education is suitable and identify current gaps in research. The databases EMBASE, OVID MEDLINE and PSYCINFO were searched for relevant articles. In total, 5241 articles were found, with an additional 15 sources found via soft searches, of which 42 met inclusion criteria and were subsequently reviewed. Sexual behaviours that occur in these adolescents with ASD include hypermasturbation, public masturbation, inappropriate romantic gestures, inappropriate arousal and exhibitionism. Such behaviours are thought to be caused via a lack of understanding of normal puberty, the absence of appropriate sex education, the severity of their ASD and other associated problems. It is suggested that individualized, repetitive education should be started from an early age in an accessible form. Social skills development is also important before more technical aspects of sex education are taught. Despite being such a common problem for schools, institutions and families to manage, it is surprising how sparse literature is particularly regarding why inappropriate behaviour occurs and what education is effective. © 2015 Wiley Publishing Asia Pty Ltd.

    The Gram-positive bacterium, Staphylococcus aureus (S. aureus), is a major pathogen responsible for a variety of infectious diseases ranging from cellulitis to more serious conditions such as septic arthritis and septicaemia. Timely treatment with appropriate antibiotic therapy is essential to ensure clinical defervescence and to prevent further complications such as infective endocarditis or organ impairment due to septic shock. To date, initial antibiotic choice is empirical, using a "best guess" of likely organism and sensitivity- an approach adopted due to the lack of rapid identification methods for bacteria. Current culture based methods take up to 5 days to identify the causative bacterial pathogen and its antibiotic sensitivity. This paper provides proof of concept for a biosensor, based on interdigitated electrodes, to detect the presence of S. aureus and ascertain its sensitivity to flucloxacillin rapidly (within 2 hours) in a cost effective manner. The proposed method is label-free and uses non-faradic measurements. This is the first study to successfully employ interdigitated electrodes for the rapid detection of antibiotic resistance. The method described has important potential outcomes of faster definitive antibiotic treatment and more rapid clinical response to treatment.

    There is an increasing evidence of medicines related issues such as inappropriate prescribing among older people. Inappropriate prescribing is an important risk factor for adverse drug reactions and hospitalizations in the older people. To assess and characterize the prevalence of Potentially Inappropriate Medications (PIMs) in nursing home care in Malaysia as defined by Screening Tool of Older Peoples Prescriptions (STOPP) and Beers criteria. Four Nursing Homes situated in Penang, Malaysia. A multicenter and cross-sectional study was conducted over 2 months period at four large non-governmental organizations nursing homes in Penang, Malaysia. The study population included older residents (≥65 years old) taking at least one medication. Residents who had been diagnosed with dementia or taking anti dementia drugs, delirium, too frail or refused to give consent were excluded. Demographic, clinical data and concurrent medications were collected through direct interview and also by reviewing medical records. STOPP and Beers criteria were applied in the medical review to screen for PIMs. Potentially Inappropriate Medication using STOPP and Beers criteria. Two hundred eleven residents were included in the study with the median age of 77 (inter quartile range (IQR) 72-82) years. Median number of prescription medicines was 4 (IQR 1-14). STOPP identified less residents (50 residents, 23.7 %) being prescribed on PIMs compared with Beers criteria (69 residents, 32.7 %) (p older residents living in the nursing homes and are associated with number of medications and longer nursing home stay. Further research is warranted to study the impact of PIMs towards health related outcomes in these elderly.

    Mak, Stefanie; Xu, Ye; Nodwell, Justin R

    2014-08-01

    Antibiotic-producing bacteria encode antibiotic resistance genes that protect them from the biologically active molecules that they produce. The expression of these genes needs to occur in a timely manner: either in advance of or concomitantly with biosynthesis. It appears that there have been at least two general solutions to this problem. In many cases, the expression of resistance genes is tightly linked to that of antibiotic biosynthetic genes. In others, the resistance genes can be induced by their cognate antibiotics or by intermediate molecules from their biosynthetic pathways. The regulatory mechanisms that couple resistance to antibiotic biosynthesis are mechanistically diverse and potentially relevant to the origins of clinical antibiotic resistance. © 2014 John Wiley & Sons Ltd.

    Many healthcare facilities enforce security on their electronic health records (EHRs) through a corrective mechanism: some staff nominally have almost unrestricted access to the records, but there is a strict ex post facto audit process for inappropriate accesses, i.e., accesses that violate the facility's security and privacy policies. This process is inefficient, as each suspicious access has to be reviewed by a security expert, and is purely retrospective, as it occurs after damage may have been incurred. This motivates automated approaches based on machine learning using historical data. Previous attempts at such a system have successfully applied supervised learning models to this end, such as SVMs and logistic regression. While providing benefits over manual auditing, these approaches ignore the identity of the users and patients involved in a record access. Therefore, they cannot exploit the fact that a patient whose record was previously involved in a violation has an increased risk of being involved in a future violation. Motivated by this, in this paper, we propose a collaborative filtering inspired approach to predicting inappropriate accesses. Our solution integrates both explicit and latent features for staff and patients, the latter acting as a personalized "finger-print" based on historical access patterns. The proposed method, when applied to real EHR access data from two tertiary hospitals and a file-access dataset from Amazon, shows not only significantly improved performance compared to existing methods, but also provides insights as to what indicates an inappropriate access.

    In primary care, patients with chronic kidney disease (CKD) are frequently prescribed excessive doses of antibiotics relative to their kidney function. We examined whether nephrology comanagement is associated with improved prescribing in primary care. In a retrospective propensity score-matched cross-sectional study, we studied the appropriateness of antibiotic prescriptions by primary care physicians to Ontarians ≥66 years of age with CKD Stages 4 and 5 (estimated glomerular filtration rate <30 mL/min/1.73 m2 not receiving dialysis) from 1 April 2003 to 31 March 2014. Comanagement was defined as having at least one outpatient visit with a nephrologist within the year prior to antibiotic prescription date. We compared the rate of appropriately dosed antibiotics in primary care between 3937 patients who were comanaged by a nephrologist and 3937 patients who were not. Only 1184 (30%) of 3937 noncomanaged patients had appropriately dosed antibiotic prescriptions prescribed by a primary care physician. Nephrology comanagement was associated with an increased likelihood that an appropriately dosed prescription was prescribed by a primary care physician; however, the magnitude of the effect was modest [1342/3937 (34%); odds ratio 1.20 (95% confidence interval 1.09-1.32); P < 0.001]. The majority of antibiotics prescribed by primary care physicians are inappropriately dosed in CKD patients, whether or not a nephrologist is comanaging the patient. Nephrologists have an opportunity to increase awareness of appropriate dosing of medications in primary care through the patients they comanage.

    Antibiotics are essential for the treatment of bacterial infections and are among our most important drugs. Resistance has emerged to all classes of antibiotics in clinical use. Antibiotic resistance has, proven inevitable and very often it emerges rapidly after the introduction of a drug into the clinic. There is, therefore, a great interest in understanding the origins, scope and evolution of antibiotic resistance. The review discusses the concept of the antibiotic resistome, which is the collection of all genes that directly or indirectly contribute to antibiotic resistance. The review seeks to assemble current knowledge of the resistome concept as a means of understanding the totality of resistance and not just resistance in pathogenic bacteria. The concept of the antibiotic resistome provides a framework for the study and understanding of how resistance emerges and evolves. Furthermore, the study of the resistome reveals strategies that can be applied in new antibiotic discoveries.

    Water scarcity is a global problem, and is particularly acute in certain regions like Africa, the Middle East, as well as the western states of America. A breakdown on water usage revealed that 70% of freshwater supplies are used for agricultural irrigation. The use of reclaimed water as an alternative water source for agricultural irrigation would greatly alleviate the demand on freshwater sources. This paradigm shift is gaining momentum in several water scarce countries like Saudi Arabia. However, microbial problems associated with reclaimed water may hinder the use of reclaimed water for agricultural irrigation. Of particular concern is that the occurrence of antibiotic residues in the reclaimed water can select for antibiotic resistance genes among the microbial community. Antibiotic resistance genes can be associated with mobile genetic elements, which in turn allow a promiscuous transfer of resistance traits from one bacterium to another. Together with the pathogens that are present in the reclaimed water, antibiotic resistant bacteria can potentially exchange mobile genetic elements to create the “perfect microbial storm”. Given the significance of this issue, a deeper understanding of the occurrence of antibiotics in reclaimed water, and their potential influence on the selection of resistant microorganisms would be essential. In this review paper, we collated literature over the past two decades to determine the occurrence of antibiotics in municipal wastewater and livestock manure. We then discuss how these antibiotic resistant bacteria may impose a potential microbial risk to the environment and public health, and the knowledge gaps that would have to be addressed in future studies. Overall, the collation of the literature in wastewater treatment and agriculture serves to frame and identify potential concerns with respect to antibiotics, antibiotic resistant bacteria, and antibiotic resistance genes in reclaimed water.

    Antibiotics are among the most important interventions in healthcare. Resistance of bacteria to antibiotics threatens the effectiveness of treatment. Systematic reviews of antibiotic treatments often do not address resistance to antibiotics even when data are available in the original studies....... This omission creates a skewed view, which emphasizes short-term efficacy and ignores the long-term consequences to the patient and other people. We offer a framework for addressing antibiotic resistance in systematic reviews. We suggest that the data on background resistance in the original trials should...... controlled trials or systematic reviews....

    Full Text Available El uso inadecuado de antibióticos representa un riesgo para la salud y un desperdicio de recursos económicos en los servicios de salud. Además, contribuye al aumento de la resistencia bacteriana que, a su vez, incrementa los gastos y la mortalidad por enfermedades infecciosas, por lo que se le considera un grave problema de salud pública. Al respecto, la Organización Mundial de la Salud ha recomendado una serie de estrategias fundadas en las políticas farmacéuticas nacionales. En México, diversos aspectos sobre el uso inapropiado de antibióticos han sido documentados. En respuesta se han desarrollado principalmente intervenciones educativas y gerenciales dirigidas a médicos en servicios públicos de salud, así como programas de vigilancia epidemiológica. La investigación y las intervenciones enfocadas en consumidores, farmacias y el sector privado son escasas. Fundamentalmente, no existe una estrategia nacional sobre antibióticos que se refleje en las políticas farmacéuticas y de salud del país.The inappropriate use of antibiotics signifies a risk for individual health and a waste of health resources. It triggers the development of antibiotic resistance, which increases expenditures and mortality related to infectious disease, and is hence considered a serious public health problem. The World Health Organization has thus recommended a series of strategies to be included within national pharmaceutical policies. In Mexico, diverse factors related to the inappropriate use of antibiotics have been documented. While the response has been mainly in the form of educational and managerial interventions directed toward physicians in public health services, as well as epidemiological surveillance, there is a paucity of research and interventions focused on consumers, pharmacies, and the private sector. Fundamentally, a comprehensive national strategy for antibiotics is not incorporated into health and pharmaceutical policies.

    Despite the fact that the ever growing relevance of the problem of the inappropriate medical care was long ago brought to the worldwide attention, it has not been practically addressed in the Ukraine since the country gained independence in 1991. The objective of the present study was to consider the specific features of expert examination of the cases of inappropriate medical care as exemplified by the materials of the legal actions and lawsuits instituted against healthcare specialists violating their occupational duties. The results of forensic medical examination by the local Bureaux of forensic medical expertise concerning the 350 so-called malpractice suits instituted in the Ternopol, Zhitomir, and Chernovtsy regions during the period from 207 to 2016 were available for the analysis. The facts of inadequate and inappropriate medical care were documented in 245 (72.0%) cases. The frequency of diagnostic and therapeutic errors amounted to 29.7% and 26.9% respectively while the improper formulation of the medical documentation was recorded in 21.3% of the cases. The cases of poor organization of the diagnostic and treatment process accounted for 14.6% of the total whereas the improper behaviour of the medical personnel was reported in 7.5% of all the known cases of provision of the healthcare services. It is concluded that in the majority of the cases, the citizens of the modern-day Ukraine receive the inappropriate (insufficient and untimely) medical care. Over 80% of the cases of the inappropriate medical care currently provided in the country can be accounted for by the objective reasons, with each fifths case being due to the violation of professional responsibilities by the healthcare providers.

    The objective of this study was to establish how antibiotic prescribing policies at National Health Service (NHS) hospitals match the England Department of Health 'Start Smart-Then Focus' recommendations and relate to Clostridium difficile infection (CDI) rates. Antibiotic pharmacists were surveyed regarding recommendations for empirical treatment of common syndromes ('Start Smart') and antimicrobial prescription reviews ('Focus') at their hospital trusts. If no response was provided, policy data were sought from trust websites and the MicroGuide app (Horizon Strategic Partners, UK). Empirical treatment recommendations were categorized as broad spectrum (a β-lactam penicillin/β-lactamase inhibitor, cephalosporin, quinolone or carbapenem) or narrow spectrum. CDI rates were gathered from the national mandatory surveillance system. Data were obtained for 105/145 English acute hospital trusts (72%). β-Lactam/β-lactamase inhibitor combinations were recommended extensively. Only for severe community-acquired pneumonia and pyelonephritis were narrow-spectrum agents recommended first line at a substantial number of trusts [42/105 (40%) and 50/105 (48%), respectively]. Policies commonly recommended dual therapy with aminoglycosides and β-lactams for abdominal sepsis [40/93 trusts (43%)] and undifferentiated severe sepsis [54/94 trusts (57%)]. Most policies recommended treating for ≥ 7 days for most indications. Nearly all policies [100/105 trusts (95%)] recommended antimicrobial prescription reviews, but only 46/96 respondents (48%) reported monitoring compliance. Independent predictors of higher CDI rates were recommending a broad-spectrum regimen for community-acquired pneumonia (P=0.06) and, counterintuitively, a recommended treatment duration of Smart' by recommending broad-spectrum antibiotics for empirical therapy, but this may have the unintended potential to increase the use of broad-spectrum antibiotics and risk of CDI unless better mechanisms are in place

    We aimed to reliably describe the pattern of outpatient prescription of non-steroidal anti-inflammatory drugs (NSAIDs) and antibiotics (ATBs) at a central hospital in the West Bank, Palestine. This was a retrospective, cross-sectional study investigating a cohort of 2,208 prescriptions ordered by outpatient clinics and the emergency room over one year in Beit Jala Hospital in Bethlehem, West Bank. The orders were analysed for the rate and types of NSAIDs and ATBs utilised, and the appropriateness of these drugs to the diagnosis. Of the total prescriptions, 410 contained NSAIDs (18.6%), including diclofenac (40.2%), low dose aspirin (23.9%), ibuprofen (17.8%) and indomethacin (15.1%). A minority of these prescriptions contained a combination of these agents (2.5%). Only one prescription contained cyclooxyeganse-2 inhibitors (0.2%). The appropriateness of NSAID use to the diagnosis was as follows: appropriate (58.3%), inappropriate (14.4%) and difficult to tell (27.3%). The rate of ATB use was 30.3% (669 prescriptions). The ATBs prescribed were amoxicillin (23.3%), augmentin (14.3%), quinolones (12.7%), first and second generation cephalosporins (9.4% and 12.7%, respectively) and macrolides (7.2%). ATB combinations were identified in 9.4%, with the most common being second-generation cephalopsorins and metronidazole (4.3%). Regarding the appropriateness of prescribing ATBs according to the diagnosis, it was appropriate in 44.8%, inappropriate in 20.6% and difficult to tell in 34.6% of the prescriptions. These findings revealed a relatively large number and inappropriate utilisation of ATBs and NSAIDs. An interventional programme needs to be adopted to reinforce physicians' knowledge of the rational prescription of these agents.

    Inappropriate use and overuse of antibiotics and injections are serious threats to the global population, particularly in developing countries. In recent decades, public reporting of health care performance (PRHCP) has been an instrument to improve the quality of care. However, existing evidence shows a mixed effect of PRHCP. This study evaluated the effect of PRHCP on physicians' prescribing practices in a sample of primary care institutions in China. Segmented regression analysis was used to produce convincing evidence for health policy and reform. The PRHCP intervention was implemented in Qian City that started on 1 October 2013. Performance data on prescription statistics were disclosed to patients and health workers monthly in 10 primary care institutions. A total of 326 655 valid outpatient prescriptions were collected. Monthly effective prescriptions were calculated as analytical units in the research (1st to 31st every month). This study involved multiple assessments of outcomes 13 months before and 11 months after PRHCP intervention (a total of 24 data points). Segmented regression models showed downward trends from baseline on antibiotics (coefficient = -0.64, P = 0.004), combined use of antibiotics (coefficient = -0.41, P < 0.001) and injections (coefficient = -0.5957, P = 0.001) after PRHCP intervention. The average expenditure of patients slightly increased monthly before the intervention (coefficient = 0.8643, P < 0.001); PRHCP intervention also led to a temporary increase in average expenditure of patients (coefficient = 2.20, P = 0.307) but slowed down the ascending trend (coefficient = -0.45, P = 0.033). The prescription rate of antibiotics and injections after intervention (about 50%) remained high. PRHCP showed positive effects on physicians' prescribing behaviour, considering the downward trends on the use of antibiotics and injections and average expenditure through the intervention. However, the effect

    Full Text Available Abstract Background Explicit criteria for determining potentially inappropriate medication consumption in elderly were elaborated by Beers et al. These lists have been used worldwide to evaluate medical prescriptions but there is little epidemiologic evidence demonstrating negative consequences of inappropriate medication use. It has been reported that some drugs could increase the risk of falls, which are a frequent and serious problem in elderly population. We aimed to evaluate the association between the use of potentially inappropriate medications and the risk of falls. Methods The 3C Study is a multicentre prospective cohort study conducted in France with 4 years of follow-up. Non-institutionalized men and women aged 65 years or over (N = 6343 were randomly selected from electoral rolls. Data on socio-demographic, medical characteristics and medication use (based on self-reports and data from the national healthcare insurance were collected. Use of inappropriate medication for elderly was defined from established criteria. Data about falls were collected at the two follow-up examinations (2 years and 4 years after baseline. The association between the exposure to inappropriate medications and the risk of falls was evaluated using multivariate models (Cox model and logistic regression. Results 32% of subjects reported inappropriate medication use at baseline and 29% at least two of the three examinations; 22% had fallen 2 times or more during follow-up. Overall, inappropriate medication users had an increased risk of falling. This increase was mainly due to the use of long-acting benzodiazepines (adjusted odds ratio (OR = 1.4, 95% confidence interval: [1.1–1.8], in both occasional and regular users, other inappropriate psychotropics (adjusted OR = 1.7 [1.7–2.7] in regular users, or medication with anticholinergic properties (adjusted OR = 1.6 [1.2–2.1] in regular users.

    The "choosing wisely" recommendations of the German Society of Internal Medicine (DGIM) and its specialist societies address diagnostic and therapeutic procedures, which are of particular medical importance but applied too often or too rarely in clinical practice. The aim is to further improve treatment of patients. Important topics of overuse and insufficient treatment related to the diagnostics, therapy, prevention and exclusion of infectious diseases could be identified. These topics not only play an important role in the discipline of infectious diseases but are also relevant for other internal medical disciplines. These topics related to infectious diseases have also been integrated into the recommendations of the German Society of Gastroenterology, Digestive and Metabolic Diseases as well as the German Societies for Internal Intensive Care and Emergency Medicine, for Pneumology, for Nephrology and for Rheumatology. The pivotal issues of the recommendations are the inappropriate use of antibiotics and insufficient vaccination rates.

    Full Text Available Background: Current algorithms and device morphology templates have been proposed in current Implantable Cardioverter-Defibrillators (ICDs to minimize inappropriate therapies (ITS, but this has not been completely successful. Aim: Assess the impact of a deliberate strategy of using an atrial lead implant with standardized parameters; based on all current ICD discriminators and technologies, on the burden of ITS. Method: A retrospective single-centre analysis of 250 patients with either dual chamber (DR ICDs or biventricular ICDs (CRTDs over a (41.9 ± 27.3 month period was performed. The incidence of ITS on all ICD and CRTD patients was chronicled after the implementation of standardized programming. Results: 39 events of anti-tachycardial pacing (ATP and/or shocks were identified in 20 patients (8% incidence rate among patients. The total number of individual therapies was 120, of which 34% were inappropriate ATP, and 36% were inappropriate shocks. 11 patients of the 250 patients received ITS (4.4%. Of the 20 patients, four had ICDs for primary prevention and 16 for a secondary prevention. All the episodes in the primary indication group were inappropriate, while seven patients (43% of the secondary indication group experienced inappropriate therapies. Conclusions: The burden of ITS in the population of patients receiving ICDs was 4.4% in the presence of atrial leads. The proposed rationalized programming criteria seems an effective strategy to minimize the burden of inappropriate therapies and will require further validation.

    Antimicrobial resistance has become a global burden for which inappropriate antimicrobial use is an important contributing factor. Any decisions on the selection of antibiotics use should consider their effects on antimicrobial resistance. The objective of this study was to assess the extent to which antibiotic prescribing guidelines have considered resistance patterns when making recommendations for five highly prevalent infectious syndromes. We used Medline searches complemented with extensive use of Web engine to identify guidelines on empirical treatment of community-acquired pneumonia, urinary tract infections, acute otitis media, rhinosinusitis and pharyngitis. We collected data on microbiology and resistance patterns and identified discrete pattern categories. We assessed the extent to which recommendations considered resistance, in addition to efficacy and safety, when recommending antibiotics. We identified 135 guidelines, which reported a total of 251 recommendations. Most (103/135, 79%) were from developed countries. Community-acquired pneumonia was the syndrome mostly represented (51, 39%). In only 16 (6.4%) recommendations, selection of empirical antibiotic was discussed in relation to resistance and specific microbiological data. In a further 69 (27.5%) recommendations, references were made in relation to resistance, but the attempt was inconsistent. Across syndromes, 12 patterns of resistance with implications on recommendations were observed. 50% to 75% of recommendations did not attempt to set recommendation in the context of these patterns. There is consistent evidence that guidelines on empirical antibiotic use did not routinely consider resistance in their recommendations. Decision-makers should analyse and report the extent of local resistance patterns to allow better decision-making. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    In 2016/2017, a financially linked antibiotic prescribing quality improvement initiative Commissioning for Quality and Innovation (AMR-CQUIN) was introduced across acute hospitals in England. This aimed for >1% reductions in DDDs/1000 admissions of total antibiotics, piperacillin/tazobactam and carbapenems compared with 2013/2014 and improved review of empirical antibiotic prescriptions. To assess perceptions of staff leading antimicrobial stewardship activity regarding the AMR-CQUIN, the investments made by hospitals to achieve it and how these related to achieving reductions in antibiotic use. We invited antimicrobial stewardship leads at acute hospitals across England to complete a web-based survey. Antibiotic prescribing data were downloaded from the PHE Antimicrobial Resistance Local Indicators resource. Responses were received from 116/155 (75%) acute hospitals. Owing to yearly increases in antibiotic use, most trusts needed to make >5% reductions in antibiotic consumption to achieve the AMR-CQUIN goal of 1% reduction. Additional funding was made available at 23/113 (20%) trusts and, in 18 (78%), this was trend for increased antibiotic use reversed in 2016/2017. In 2014/2015, year-on-year changes were +3.7% (IQR -0.8%, +8.4%), +9.4% (+0.2%, +19.5%) and +5.8% (-6.2%, +18.2%) for total antibiotics, piperacillin/tazobactam and carbapenems, respectively, and +0.1% (-5.4%, +4.0%), -4.8% (-16.9%, +3.2%) and -8.0% (-20.2%, +4.0%) in 2016/2017. Hospitals where staff believed they could reduce antibiotic use were more likely to do so (P < 0.001). Introducing the AMR-CQUIN was associated with a reduction in antibiotic use. For individual hospitals, achieving the AMR-CQUIN was associated with favourable perceptions of staff and not availability of funding.

    Urinary tract infections (UTIs) are common infections affecting children. The aim of our study is to determine microorganisms that cause community-acquired urinary tract infections and their antibiotic susceptibility in children. Our investigation includes 150 cases which has positive urine culture. The cases are detected at Pediatric Polyclinics of Dicle University between June 2010 and June 2011. The study included 118 (78.7%) female and 32 (21.3%) male children. Urinary tract infections were seen in autumn 10.7% (n = 16), summer 35.3% (n = 53), winter 30.7% (n = 46) and spring 23.3% (n = 35). The culture results indicated 75.3% (n = 113) Escherichia coli; 20.7% (n = 31) Klebsiella; 2.7% (n = 4) Proteus and % 1.3 (n = 2) Pseudomonas. The antibiotic resistance against Escherichia coli was found out is amikacin (3%), ertapenem (7%), imipenem (0%), meropenem (0%), nitrofurantoin (9%), trimethoprim/sulfamethoxazole (58%), piperacillin (83%), amoxicillin/clavulanate (50%), ampicillin/sulbactam (65%), cefazolin (54%), cefotaxime (51%), cefuroxime sodium (51% ) and tetracycline (68%). The resistance ratios of Klebsiella are amikacin (0%), imipenem (0%), levofloxacin (0%), meropenem (0%), amoxicillin/clavulanate (57%), ampicillin/sulbactam (79%), ceftriaxone (68%), cefuroxime sodium (74%) and trimethoprim/sulfamethoxazole (61%). The results represent the increasing antibiotic resistance against microorganisms among the community-acquired UTI patients in a developing country such as Turkey. So, the physicians should consider resistance status of the infectious agent and choose effective antibiotics which are nitrofurantoin and cefoxitin for their empirical antibiotic treatment. Furthermore, they should be trained about selection of more effective antibiotics and check the regional studies regularly.

    Majority of acute diarrhoeal diseases are self-limiting and do not require routine treatment. Treatment with empirical antimicrobials is recommended only for dysenteric and invasive bacterial diarrhoea. Irrational use of antibiotics in treatment of acute diarrhoea is common in clinical practice worldwide. This study was carried out to assess the pattern of antibiotic use for acute diarrhoeal diseases in Bishoftu General Hospital, East Shewa Ethiopia. Institution based cross-sectional study was conducted from April 1 to April 30, 2016. Data were collected retrospectively from patients treated for diarrhoeal diseases from January 2015 to December 2015 using structured questionnaires and entered into SPSS (IBM 20) and descriptive statistics was carried out. Among the 303 patients, 51.2% were males and 48.8% were females. Of them, 62% were children under five years. Two hundred sixty three (86.8%) patients received eight different types of antibiotics and cotrimoxazole (178 patients, 58.7%) was the most prescribed antibiotics, followed by ciprofloxacin (33, 10.9%) and amoxicillin (14, 4.6%). Based on the presence of blood in stools, 14.5% of cases were of invasive bacterial type. According to the recommendations of WHO, the rate of overuse of antibiotics was 72.3%. This study revealed that there was high overuse of antibiotics for both adults and children under five with acute diarrhoea in Bishoftu General Hospital. And Cotrimoxazole was the most prescribed antibiotic.

  19. Impact of antibiotics on necrotizing enterocolitis and antibiotic-associated diarrhea

    Summary Antibiotics induce changes or dysbiosis of the intestinal microbiome. These antibiotic-induce changes may contribute to the pathogenesis of necrotizing enterocolitis (NEC) and antibiotic-associated diarrhea (AAD). Studies are beginning to unravel the contribution of specific groups of microbes to these diseases—most notably Gammaproteobacteria for NEC and bile acid- and carbohydrate-metabolizing microbes for AAD. Antibiotic-associated diarrhea occurs when antibiotic treatment induces diarrhea by altering the metabolic function of the patient’s intestinal microbiota leading to either an osmotic or infectious diarrhea, most notably Clostridium difficile infection (CDI). Antibiotic therapy impairs the host microbiota’s ability to resist colonization or expansion of pathogenic bacteria. In the case of CDI, there is growing evidence that microbiota-mediated bile acid metabolism is critical in the pathogenesis of this infection. Probiotics or other microbiota-targeted therapies may provide effective strategies to prevent and treat NEC and AAD. PMID:28164853

  20. Emergency Department Management of a Myasthenia Gravis Patient with Community-Acquired Pneumonia: Does Initial Antibiotic Choice Lead to Cure or Crisis?

    Myasthenic crisis is a rare, yet serious condition that carries a 3%-8% mortality rate. Although infection is a common cause of decompensation in myasthenia gravis, several antibiotics classes have also been associated with an exacerbation. Selecting antibiotics can be a daunting clinical task and, if chosen inappropriately, can carry significant deleterious consequences. Not only do clinicians have to focus on treating the underlying infection appropriately, but avoiding antibiotics that may potentiate a myasthenic crisis is also vital. An 85-year-old female with a history of myasthenia gravis presented to the emergency department (ED) with increasing generalized weakness and shortness of breath. Clinical work-up was consistent with a community-acquired pneumonia (CAP) diagnosis. Her medical history included a myasthenia gravis exacerbation shortly after receiving moxifloxacin for CAP. After reviewing the patient's allergies, as well as potential antibiotic triggers, the decision was made to treat with tigecycline. The patient responded well to tigecycline therapy and was deemed stable for discharge on day 4 of hospitalization. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Evaluation of the myasthenia gravis patient frequently originates in the ED. It is important for clinicians to be able to distinguish between an underlying illness and a myasthenic crisis. In the event of an infectious process causing clinical deterioration in a myasthenia patient, optimal antibiotic selection becomes paramount. This patient case highlights the addition of tigecycline to the armamentarium of therapies available to treat myasthenia gravis patients presenting to the emergency department with CAP.

    Dementia of Lewy body disease is the second most common degenerative cause of dementia after Alzheimer's disease, among all the dementias. The core features are a progressive dementia, fluctuations in cognitive functions, visual hallucinations, and spontaneous parkinsonism. Rapid eye movement sleep behavior disorder, severe neuroleptic sensitivity, and low dopamine transporter uptake in basal ganglia are other suggestive features. Behavioral abnormalities are commonly present in the form of aggressive behavior, irritability, and uninhibited behaviors. These are mostly seen in the advanced stages of dementia. However, inappropriate sexual behavior is uncommonly seen in such cases. Three types of inappropriate sexual behaviors commonly found in cases of dementia are sex talks, sexual acts, and implied sexual acts. Such inappropriate sexual behaviors have not been described adequately in dementia of Lewy body disease. We report inappropriate sexual behaviors in a case of dementia of Lewy body disease, which improved rapidly after treatment with quetiapine.

    Background and objectives

     As a common infectious disease in childhood, shigellosis has a variety of seasonal and microbiologic patterns and there is a concerning trend of resistance in various parts of the world and even a single country. Inappropriate empiric therapy for any acute episode of gastroenteritis, which might be based on lab studies, could potentially lead to even further resistance. In this report, the erythrocyte sedimentation rate was studied in patients with acute gastroenteritis.

     

    Methods

     Medical records of 117 patients were reviewed in this study. The mean and standard deviation of some of the acute phase inflammatory indicators were compared in two groups of shigellosis and viral gastroenteritides using independent samples t test.

     

    Results

     The mean age of the patients was 49 months, and almost half of them were male. Shigella sonnei was the commonest species isolated from these patients. Shigellosis was found to be more frequent during August to October. After 2001, resistance to ampicillin and cotrimoxazole was observed in 75% and 90% of isolates respectively. A few cases were resistant to third generation of cephalosporins (< 3%. In shigellosis, the erythrocyte sedimentation rate was significantly higher than viral gastroenteritis.

     

    Conclusion

     Empiric use of cotrimoxazole is no longer recommended in children suspicious of contracting shigellosis in Tehran. To avoid unnecessary prescription of antibiotics for acute gastroenteritis, a normal result of erythrocyte sedimentation rate might be helpful.

    Ventilator-associated pneumonia (VAP) is very common in many intensive care Units, but there are still many uncertainties about VAP, especially about the choice of initial empiric antibiotics. The incidence of specific pathogens with different susceptibility patterns causing VAP varies from hospital to hospital. This is the reason why empiric initial antibiotic treatment for VAP should be based not only on general guidelines (that recommend therapy according to the presence of risk factors for multidrug-resistant bacteria), but also on up-to-date information on local epidemiology. The aim of this study was to determine the microbial profile of pathogens causing VAP and their antibiotic susceptibility patterns. The study was conducted in the 15-bed surgical and neurosurgical Intensive Care Unit, Department of Anesthesiology and Intensive Care, Sestre milosrdnice University Hospital Center, Zagreb, Croatia. Retrospective data were collected from September 2009 to March 2013. All patients that developed VAP during the study period were eligible for the study. According to study results, the incidence of VAP was 29.4%. The most commonly isolated bacterium was Staphylococcus aureus (21.1%), followed by Pseudomonas aeruginosa (19.0%) and Acinetobacter species (13.6%). All Staphylococcus aureus isolates were susceptible to vancomycin and linezolid. Pseudomonas aeruginosa showed 100% susceptibility to cefepime and very high susceptibility to pip'eracillin-tazobactam (96%), ceftazidime (93%) and ciprofloxacin (89%). Ampicillin-sulbactam was highly effective for Acinetobacter species, showing resistance in only 8% of isolates. In conclusion, according to study data, appropriate empiric antibiotic therapy for patients with VAP without risk factors for multidrug-resistant bacteria is ceftriaxone and for patients with risk factors for multidrug-resistant bacteria ampicillin-sulbactam plus cefepime plus vancomycin or linezolid.

    Contrast methods to assess the health effects of a treatment rate change when treatment benefits are heterogeneous across patients. Antibiotic prescribing for children with otitis media (OM) in Iowa Medicaid is the empirical example. Instrumental variable (IV) and linear probability model (LPM) are used to estimate the effect of antibiotic treatments on cure probabilities for children with OM in Iowa Medicaid. Local area physician supply per capita is the instrument in the IV models. Estimates are contrasted in terms of their ability to make inferences for patients whose treatment choices may be affected by a change in population treatment rates. The instrument was positively related to the probability of being prescribed an antibiotic. LPM estimates showed a positive effect of antibiotics on OM patient cure probability while IV estimates showed no relationship between antibiotics and patient cure probability. Linear probability model estimation yields the average effects of the treatment on patients that were treated. IV estimation yields the average effects for patients whose treatment choices were affected by the instrument. As antibiotic treatment effects are heterogeneous across OM patients, our estimates from these approaches are aligned with clinical evidence and theory. The average estimate for treated patients (higher severity) from the LPM model is greater than estimates for patients whose treatment choices are affected by the instrument (lower severity) from the IV models. Based on our IV estimates it appears that lowering antibiotic use in OM patients in Iowa Medicaid did not result in lost cures.

    Antibiotics are among the most important interventions in healthcare. Resistance of bacteria to antibiotics threatens the effectiveness of treatment. Systematic reviews of antibiotic treatments often do not address resistance to antibiotics even when data are available in the original studies. This omission creates a skewed view, which emphasizes short-term efficacy and ignores the long-term consequences to the patient and other people. We offer a framework for addressing antibiotic resistance in systematic reviews. We suggest that the data on background resistance in the original trials should be reported and taken into account when interpreting results. Data on emergence of resistance (whether in the body reservoirs or in the bacteria causing infection) are important outcomes. Emergence of resistance should be taken into account when interpreting the evidence on antibiotic treatment in randomized controlled trials or systematic reviews. © The Author 2016.

    Full Text Available Traditionally, there has been no place for sexuality in older age. However, research has shown that sexuality plays an important role in older people’s life, even in situations such as dementia. The goal of the article is to review the scientific literature regarding the inappropriate sexual behavior that these kind of patients might present. In order to do so, we will firstly address the definition of inappropriate sexual behavior or, more precisely, its multiple definitions. After that, we will deal with other issues such as its prevalence, factors that can cause its appearance, its consequences and some of the available therapeutic options. Finally, in the last section some recommendations for future research will be provided, such as the need to clarify the concept of inappropriate sexual behavior, to find more efficient ways to address this problem, and the desirability of considering sexuality as a human dimension with a high potential for adaptation in old age.

    Full Text Available There is a growing concern worldwide about the prevalence of antibiotics and antibiotic resistance genes (ARGs on the farm. In this study, we investigated the distribution of seven antibiotics and ten ARGs in fresh and dried pig feces, in biogas slurry, and in grape-planting soil from an ecological farm. Antibiotics including sulfamethazine, norfloxacin, ofloxacin, tetracycline, oxytetracycline, and chlortetracycline were detected in these samples (except for sulfamethoxazole in dried feces. In general, antibiotics levels in samples were in the sequence: biogas slurry > fresh feces > soil or dried feces. Results of ecological risk assessments revealed that among the seven antibiotics chlortetracycline showed the highest ecological risk. Among the ten ARGs, sulI and tetO were the most prevalent on this ecological farm. There were positive correlations between certain ARGs and the corresponding antibiotics on this ecological farm. Therefore, continuous monitoring of antibiotics and their corresponding ARGs should be conducted in the agroecosystem near the concentrated animal farming operation systems.

    OBJECTIVE To describe current practice around urine testing and identify factors leading to overtreatment of asymptomatic bacteriuria in community nursing homes (NHs) DESIGN Observational study of a stratified random sample of NH patients who had urine cultures ordered in NHs within a 1-month study period SETTING 31 NHs in North Carolina PARTICIPANTS 254 NH residents who had a urine culture ordered within the 1-month study period METHODS We conducted an NH record audit of clinical and laboratory information during the 2 days before and 7 days after a urine culture was ordered. We compared these results with the urine antibiogram from the 31 NHs. RESULTS Empirical treatment was started in 30% of cases. When cultures were reported, previously untreated cases received antibiotics 89% of the time for colony counts of ≥100,000 CFU/mL and in 35% of cases with colony counts of 10,000-99,000 CFU/mL. Due to the high rate of prescribing when culture results returned, 74% of these patients ultimately received a full course of antibiotics. Treated and untreated patients did not significantly differ in temperature, frequency of urinary signs and symptoms, or presence of Loeb criteria for antibiotic initiation. Factors most commonly associated with urine culture ordering were acute mental status changes (32%); change in the urine color, odor, or sediment (17%); and dysuria (15%). CONCLUSIONS Urine cultures play a significant role in antibiotic overprescribing. Antibiotic stewardship efforts in NHs should include reduction in culture ordering for factors not associated with infection-related morbidity as well as more scrutiny of patient condition when results become available.

    Full Text Available Postoperative surgical site infections are a major source of illness.  Infection results in longer hospital stay and higher costs.  Uses of preoperative antibiotics have been standardized and are being used routinely in most clinical surgeries and include controversial areas like breast surgery and herniorraphy. Objective of the study is to find out the benefit of prophylactic use of antibiotics in the management of herniorraphy.This project was carried out in a multispeciality tertiary care teaching hospital from 1st-30th April in 2002. Group 1 patients were treated prophylactically half an hour before surgery with single dose of I.V. antibiotics (injection.  Ampicillin 1gm + injection.  Gentamicin 80mg. Group 2 patients were treated post surgery with capsule. Ampicillin 500mg 4 times a day for 7 days and injection. Gentamicin twice a day for first 4 days. In case of group 1 patients only one out of 20 patients (5% was infected.  Whereas in-group 2 patients 5 out of 20 patients (25% were infected. The cost of prophylactic antibiotic treatment was Rs. 25.56 per patient.  The postoperative antibiotic treatment cost was Rs. 220.4 per patient.  That means postoperative treatment is around 8.62 times costlier than prophylactic treatment.             From this study it is evident that prophylactic (preoperative treatment is better than postoperative treatment with antibiotics.

    The ever increasing number of multidrug-resistant microorganism pathogens has become a great and global public health threat. Antibiotic mechanisms of action and the opposing mechanisms of resistance are intimately associated, but comprehension of the biochemical and molecular functions of such drugs is not a simple exercise. Both the environment, and genetic settings contribute to alterations in phenotypic resistance (natural bacterial evolution), and make it difficult to control the emergence and impacts of antibiotic resistance. Under such circumstances, comprehension of how bacteria develop and/or acquire antibiotic resistance genes (ARG) has a critical role in developing propositions to fight against these superbugs, and to search for new drugs. In this review, we present and discuss both general information and examples of common genetic and molecular mechanisms related to antibiotic resistance, as well as how the expression and interactions of ARGs are important to drug resistance. At the same time, we focus on the recent achievements in the search for antibiotic adjuvants, which help combat antibiotic resistance through deactivation of bacterial mechanisms of action such as β-lactamases. Recent advances involving the use of anti-resistance drugs such as: efflux pump inhibitors; anti-virulence drugs; drugs against quorum sensing; and against type II/III secretion systems are revealed. Such antibiotic adjuvants (as explored herein) collaborate against the problems of antibiotic resistance, and may restore or prolong the therapeutic activity of known antibiotics.

  15. Why your housecat's trite little bite could cause you quite a fright: a study of domestic felines on the occurrence and antibiotic susceptibility of Pasteurella multocida.

    2008-10-01

    Approximately four to five million animal bite wounds are reported in the USA each year. Domestic companion animals inflict the majority of these wounds. Although canine bites far outnumber feline bites, unlike the dog, the cat's bite is worse than its bark; 20-80% of all cat bites will become infected, compared with only 3-18% of dog bite wounds. Pasteurella multocida is the most commonly cultured bacterium from infected cat bite wounds. Anyone seeking medical attention for a cat-inflicted bite wound is given prophylactic/empiric penicillin or a derivative to prevent Pasteurella infection (provided they are not allergic to penicillins). In an effort to establish a carriage rate of P. multocida in the domestic feline, bacterial samples from the gingival margins of domestic northern Ohio cats (n=409) were cultured. Isolates were tested for antibiotic sensitivity as prophylactic/empiric use of penicillin and its derivatives could potentially give rise to antibiotic resistance in P. multocida. The high carriage rate (approximately 90%) of P. multocida observed was found to be independent of physiological and behavioural variables including age, breed, food type, gingival scale, lifestyle and sex. High antibiotic susceptibility percentages were observed for benzylpenicillin, amoxicillin-clavulanate, cefazolin, and azithromycin (100%, 100%, 98.37% and 94.02%, respectively) in P. multocida isolates. The high prevalence of P. multocida in the feline oral cavity indicates that prophylactic/empiric antibiotic therapy is still an appropriate response to cat bite wounds. Additionally, the susceptibility of P. multocida to penicillin and its derivatives indicates that they remain reliable choices for preventing and treating P. multocida infections.

    Prosthetic joint infections remain a major complication of arthroplasty. At present, local and international guidelines recommend cefazolin as a surgical antibiotic prophylaxis at the time of arthroplasty. This retrospective cohort study conducted across 10 hospitals over a 3-year period (January 2006 to December 2008) investigated the epidemiology and microbiological etiology of prosthetic joint infections. There were 163 cases of prosthetic joint infection identified. From a review of the microbiological culture results, methicillin-resistant Staphylococcus aureus (MRSA) and coagulase-negative staphylococci were isolated in 45% of infections. In addition, polymicrobial infections, particularly those involving Gram-negative bacilli and enterococcal species, were common (36%). The majority (88%) of patients received cefazolin as an antibiotic prophylaxis at the time of arthroplasty. In 63% of patients in this cohort, the microorganisms subsequently obtained were not susceptible to the antibiotic prophylaxis administered. The results of this study highlight the importance of ongoing reviews of the local ecology of prosthetic joint infection, demonstrating that the spectrum of pathogens involved is broad. The results should inform empirical antibiotic therapy. This report also provokes discussion about infection control strategies, including changing surgical antibiotic prophylaxis to a combination of glycopeptide and cefazolin, to reduce the incidence of infections due to methicillin-resistant staphylococci.

    Tamar Auerbach-Nevo

    2016-06-01

    Full Text Available Most ribosomal antibiotics obstruct distinct ribosomal functions. In selected cases, in addition to paralyzing vital ribosomal tasks, some ribosomal antibiotics are involved in cellular regulation. Owing to the global rapid increase in the appearance of multi-drug resistance in pathogenic bacterial strains, and to the extremely slow progress in developing new antibiotics worldwide, it seems that, in addition to the traditional attempts at improving current antibiotics and the intensive screening for additional natural compounds, this field should undergo substantial conceptual revision. Here, we highlight several contemporary issues, including challenging the common preference of broad-range antibiotics; the marginal attention to alterations in the microbiome population resulting from antibiotics usage, and the insufficient awareness of ecological and environmental aspects of antibiotics usage. We also highlight recent advances in the identification of species-specific structural motifs that may be exploited for the design and the creation of novel, environmental friendly, degradable, antibiotic types, with a better distinction between pathogens and useful bacterial species in the microbiome. Thus, these studies are leading towards the design of “pathogen-specific antibiotics,” in contrast to the current preference of broad range antibiotics, partially because it requires significant efforts in speeding up the discovery of the unique species motifs as well as the clinical pathogen identification.

    During the breastfeeding period, bacterial infections can occur in the nursing mother, requiring the use of antibiotics. A lack of accurate information may lead health care professionals and mothers to suspend breastfeeding, which may be unnecessary. This article provides information on the main antibiotics that are appropriate for clinical use and the interference of these antibiotics with the infant to support medical decisions regarding the discontinuation of breastfeeding. We aim to provide information on the pharmacokinetic factors that interfere with the passage of antibiotics into breast milk and the toxicological implications of absorption by the infant. Publications related to the 20 most frequently employed antibiotics and their transfer into breast milk were evaluated. The results demonstrate that most antibiotics in clinical use are considered suitable during breastfeeding; however, the pharmacokinetic profile of each drug must be observed to ensure the resolution of the maternal infection and the safety of the infant. © 2016 S.

    β-Lactam antibiotics are commonly used in outpatient parenteral antimicrobial therapy (OPAT), but data regarding outcomes of long-term therapy are limited. The purpose of this study was to compare treatment success, readmission and antibiotic switch rates in patients treated with β-lactam antibiotics as OPAT. We carried out a retrospective review of all patients, discharged from Tufts Medical Center with cefazolin, ceftriaxone, ertapenem or oxacillin, between January 2009 and June 2013. A competing risks analysis was used to compare the cumulative incidence of first occurrence of treatment success, antibiotic switch and 30 day readmission for each drug. Four hundred patients were identified (cefazolin n = 38, ceftriaxone n = 104, ertapenem n = 128 and oxacillin n = 130). Baseline demographics were similar. Treatment success rates were higher for ceftriaxone and ertapenem (cefazolin 61%, ceftriaxone 81%, ertapenem 73% and oxacillin 58%; P antibiotic switches were accomplished without readmission. Adverse drug events (ADEs) were the most common reason for outpatient antibiotic switches (31/37, 84%). The ADE rate was higher for the oxacillin group (cefazolin 2.0 versus ceftriaxone 1.5 versus ertapenem 2.9 versus oxacillin 8.4 per 1000 OPAT days; P antibiotics is effective, but antibiotic switches for adverse events were more frequent with oxacillin use. Clinicians should be cognizant of the risk of readmissions and ADEs in OPAT patients, as the value of OPAT lies in reducing patient morbidity and readmissions by managing ADEs and preventing clinical failures. © The Author 2015.

    Orbital cellulitis is conventionally managed by intravenous (i.v.) antibiotic therapy, followed by oral antibiotics once the infection shows signs of significant improvement. We report 4 years of experience using primary oral ciprofloxacin and clindamycin in cases of orbital cellulitis. Oral ciprofloxacin and clindamycin have a similar bioavailability to the i.v. preparations and provide an appropriate spectrum of antibiotic cover for the pathogens responsible for orbital cellulitis. A retrospective review was performed that identified all patients with orbital cellulitis and treated with primary oral antibiotic therapy admitted to the Manchester Royal Eye Hospital between March 2003 and March 2007. Age, stage of disease, surgical intervention, hospital duration, and complications were obtained. A comparison was made with patients admitted to our unit with orbital cellulitis and treated with primary i.v. antibiotics between March 2000 and March 2003. Nineteen patients were included in the review for the period March 2003 to March 2007, which comprised of 7 children and 12 adults. Five patients required surgical intervention. All patients responded to the oral regimen, 18 patients had no change to their oral antibiotic therapy. Mean hospital stay was 4.4 days. There were no complications. Empirical oral ciprofloxacin and clindamycin combination may be as safe and effective as i.v. therapy in the management of orbital cellulitis. Oral treatment can offer the advantages of rapid delivery of the first antibiotic dose, fewer interruptions in treatment, and simplified delivery of medication particularly in children.

    2013-11-07

    Antimicrobial resistance is a growing threat resulting from the convergence of biological, economic and political pressures. Investment in research and development of new antimicrobials has suffered secondary to these pressures, leading to an emerging crisis in antibiotic resistance. Current policies to stimulate antibiotic development have proven inadequate to overcome market failures. Therefore innovative ideas utilizing market forces are necessary to stimulate new investment efforts. Employing the benefits of both the previously described Advanced Market Commitment and a refined Call Options for Vaccines model, we describe herein a novel incentive mechanism, the Options Market for Antibiotics. This model applies the benefits of a financial call option to the investment in and purchase of new antibiotics. The goal of this new model is to provide an effective mechanism for early investment and risk sharing while maintaining a credible purchase commitment and incentives for companies to ultimately bring new antibiotics to market. We believe that the Options Market for Antibiotics (OMA) may help to overcome some of the traditional market failures associated with the development of new antibiotics. Additional work must be done to develop a more robust mathematical model to pave the way for practical implementation.

    Group A Streptococcus (GAS) pharyngitis is currently the only commonly occurring form of acute pharyngitis for which antibiotic therapy is definitely indicated. Polish guidelines advocate the use of modified Centor score (MCS) to assess the probability of GAS pharyngitis. They advise performing throat culture or rapid antigen detection test (RADT) in children with score 2-3 in MCS and treating with antibiotic only those in whom GAS was detected. Negative RADT results should be confirmed by culture. In children with score 4, the guidelines allow to introduce empiric antibiotic therapy. Phenoxymethyl penicillin is recommended as a drug of choice to treat GAS pharyngitis. The aim of our study was to evaluate the accuracy of strategy recommended by Polish guidelines in identifying those children with acute pharyngitis who require antibiotic treatment. Hence, diagnostic values of score 4 in MCS and RADT were assessed using throat culture as a reference standard. Phenoxymethyl penicillin efficacy in GAS eradication and prevention of post-streptococcal complications were estimated as well. Ninety children between 2 and 15 years of age with acute pharyngitis symptoms suggesting GAS etiology (MCS ≥ 2), participated in our study. At the initial visit MCS was evaluated and two throat swabs were collected to perform RADT and culture. In children with GAS pharyngitis treated with penicillin, microbiological cure was assessed by performing two control throat cultures. Next, children were under observation for 3 months. Positive predictive value of score 4 in MCS turned out to be 48.05% (95% CI: 36.5-59.7%). RADT sensitivity, specificity and diagnostic accuracy proved to be 100%, 96%, and 98%, respectively. GAS eradication rate in children treated with penicillin turned out to be 92.5%. No post-streptococcal sequelae occurred in any child in 3-month observation. Empiric antibiotic therapy in children with score 4 in MCS will result in significant overtreatment of those with

    Infection is a common cause of mortality and morbidity in cancer patients. Organisms are becoming resistant to antibiotics; age appears to be one of the factors responsible. We analyzed common organisms and their antibiotic sensitivity pattern in the correlation with age. This is a single institutional, retrospective analysis of all culture positive adult and pediatric cancer patients from January 2007 to December 2007. For statistical analysis, Chi-square test for trend was used and P values were obtained. Of 1251 isolates, 262 were from children 12 years of age). Gram-negative organisms were predominant (64.95) while Gram-positive constituted 35.09% of isolates. The most common source in all age groups was peripheral-blood, accounting to 47.8% of all samples. The most common organisms in adults were Pseudomonas aeruginosa (15.3%) while in children it was coagulase negative Staphylococcus aureus (19.8%). Antibiotic sensitivity was different in both groups. In pediatric group higher sensitivity was seen for Cefoparazone-sulbactum, Cefipime, Amikacin, and Tobramycin. No resistance was found for Linezolid. The isolates in both children and adults were predominantly Gram-negative though children had proportionately higher Gram-positive organisms. High-dose cytarabine use, cotrimoxazole prophylaxis, and frequent use of central lines in children especially in hematological malignancies could explain this observation. Children harbor less antibiotic resistance than adults; Uncontrolled, cumulative exposure to antibiotics in our community with increasing age, age-related immune factors and variable bacterial flora in different wards might explain the higher antibiotic resistance in adults. Thus age is an important factor to be considered while deciding empirical antibiotic therapy.

    Drug donations to developing countries may be part of medical relief operations in acute emergencies, development aid in non-emergency situations, or a corporate donations programme. After a number of documented inappropriate drug donations, the World Health Organization developed the 'Guidelines for Drug Donations', with the second and final version published in 1999. We reviewed the medical literature on drug donations since the Guidelines publication in 1999. Literature was retrieved from PubMed and other on-line databases as well as from relevant websites providing medical literature for use in developing countries. We considered the following donations to be inappropriate: (i) essential drugs in excessive quantities; (ii) mixed unused drugs (unsorted medicines and free samples); and (iii) drug dumping (large quantities of useless medicines). We retrieved 25 publications dated after 1999, including 20 and 5 from the scientific literature and 'grey' literature (technical reports, working papers), respectively. New information concerned emergencies in East Timor, Mozambique, El Salvador, Gujarat State (India), Aceh (Indonesia) and Sri Lanka. Except for East Timor and Gujarat, inappropriate donations still occurred, accounting for 85%, 37%, 70% and 80% of donations in Mozambique, El Salvador, Aceh and Sri Lanka, respectively. Very little information was found on drug donations in non-emergency situations. There are few recent reports on the compliance of drug donations with the World Health Organization guidelines. For emergency situations, there is still room for improvement. Drug donations in non-emergency situations need to be evaluated. A reform of drug donations policy is needed.

    Medical therapy including appropriate antibiotic treatment is advocated for the management of chronic rhinosinusitis (CRS), with sinus surgery reserved for treatment failures. This study investigates the microbiology of CRS and their response to culture-directed antibiotic treatment. Sinus aspirates of mucopus from 172 consecutive CRS patients, with (n=89) and without (n=83) previous antibiotic treatment, were obtained for bacterial culture at their first visit. Medical treatment which included initial empirical and subsequent culture-directed antibiotics was instituted. Endoscopic sinus surgery (FESS) was performed for patients with persistent CRS and/or complications of CRS. A follow-up of 12 months was scheduled for all patients. One hundred and twenty (69.8%) patients were treated successfully by with antibiotic-based medical therapy. Thirty-eight patients (22.1%) did not respond to medical treatment and eventually underwent FESS. The incidence of CRS with nasal polyps (CRSwNP) was higher in FESS group (n=13, 34.2%) than patients with medical treatment only (n=9, 6.7%). Staphylococcus aureus was the most common pathogen (n=43, 25%) and amongst patients with no prior antibiotic treatment, the incidence was higher in patients with CRSwNP (n=8, 53 %) than CRS without NP (CRSwoNP) (n=20, 27%). The rate of sensitivity of the cultured microbes to amoxicillin with clavulanate and cephalosporins was 78% and 70%, respectively. The microbiology of CRS in Singapore is described. Staphylococcus aureus appears to be the most common bacterial isolates in both CRS with and without nasal polyps. Medical treatment with CRS using culture-directed antibiotics is effective in the majority of patients, especially in patients without nasal polyps.

    The current economic and social context has required health systems to provide top quality services and to be efficient in controlling costs. An obstacle to achieve these goals is the inappropriate health services demand. This study aims to present these inappropriate health service demand determinants from data on telephone calls made to a medical advice call centre. This study used a Brazilian medical advice call centre data sample in the period of November and December 2012 (n = 19690), which supplied data on the user's initial request, the physician's recommendation, information on the patient and circumstances (the day and time of the day of the telephone call). The convergence between user intent and medical recommendation consists in adequate demand; otherwise the divergence consists in an inadequate one. In this way, using a logistic regression model, the critical factors that determine inappropriate health services request could be estimated. In general, the user's initial intent is the most critical for the inappropriate health system demand occurrence: the greater the complexity of the patient's initial intent, the greater the chance the intent is wrong: (OR: 1.160; 95% CI: 1.113-1.210). With regard to the social characteristics, men are more likely to make inappropriate requests (OR: 1.102; 95% CI: 1038-1169); as well as youngsters are more likely to use the system incorrectly (OR = .993; 95% CI: .992 - .994). Regarding the circumstances (day and time of the call), requests in the final hours of the day and on days close to the weekend are more likely to be the inappropriate ones (OR: 1.082 for each six hour increase; 95% CI: 1.049-1.116) and weekday (OR: 1.017 for each day increase; 95% CI: 1.002-1.032). The critical profile for the inappropriate use occurrence consists of males and youngsters, who use the health service in the final hours of the day and at weekends, and mainly want to use more complex services. A practical implication of this

    Little is known about the impact of direct-to-consumer advertising (DTCA) on appropriate versus inappropriate prescribing. Aromatase inhibitor (AI) therapy for breast cancer provides an ideal paradigm for studying this issue, because AIs have been the focus of substantial DTCA, and because they should only be used in postmenopausal women, age can serve as a simple surrogate marker of appropriateness. Data regarding national DTCA spending for the AIs were obtained from TNS Multimedia; hormonal therapy prescription data were obtained from IMS Health. Time series analyses were performed to characterize the association between monthly changes in DTCA spending for the AIs and monthly changes in the proportion of all new hormonal therapy prescriptions represented by the AIs from October 2005 to September 2007. Analyses were stratified by age, considering prescriptions for women ≤ 40 (likely premenopausal) to be inappropriate and those for women > 60 (likely postmenopausal) to be appropriate. Monthly dollars spent on AI-associated DTCA varied considerably ($118,600 to $22,019,660). Time series analysis revealed that for every million dollars spent on DTCA for the AIs, there was an associated increase 3 months later in the new AI prescription proportion of 0.15% for all ages (P 60 years (P < .0001), but no significant change for those ≤ 40 at any time from 0 to 6 months. DTCA for the AIs was associated with increases in appropriate prescriptions with no significant effect on inappropriate prescriptions, suggesting that DTCA may not foster inappropriate medication use for certain drug classes.

    Full Text Available Antibiotic resistance can be reduced by using antibiotics prudently based on guidelines of antimicrobial stewardship programs (ASPs and various data such as pharmacokinetic (PK and pharmacodynamic (PD properties of antibiotics, diagnostic testing, antimicrobial susceptibility testing (AST, clinical response, and effects on the microbiota, as well as by new antibiotic developments. The controlled use of antibiotics in food animals is another cornerstone among efforts to reduce antibiotic resistance. All major resistance-control strategies recommend education for patients, children (e.g., through schools and day care, the public, and relevant healthcare professionals (e.g., primary-care physicians, pharmacists, and medical students regarding unique features of bacterial infections and antibiotics, prudent antibiotic prescribing as a positive construct, and personal hygiene (e.g., handwashing. The problem of antibiotic resistance can be minimized only by concerted efforts of all members of society for ensuring the continued efficiency of antibiotics.

    The worldwide escalation of bacterial resistance to conventional medical antibiotics is a serious concern for modern medicine. High prevalence of multidrug-resistant bacteria among bacteria-based infections decreases effectiveness of current treatments and causes thousands of deaths. New improvements in present methods and novel strategies are urgently needed to cope with this problem. Owing to their antibacterial activities, metallic nanoparticles represent an effective solution for overcoming bacterial resistance. However, metallic nanoparticles are toxic, which causes restrictions in their use. Recent studies have shown that combining nanoparticles with antibiotics not only reduces the toxicity of both agents towards human cells by decreasing the requirement for high dosages but also enhances their bactericidal properties. Combining antibiotics with nanoparticles also restores their ability to destroy bacteria that have acquired resistance to them. Furthermore, nanoparticles tagged with antibiotics have been shown to increase the concentration of antibiotics at the site of bacterium-antibiotic interaction, and to facilitate binding of antibiotics to bacteria. Likewise, combining nanoparticles with antimicrobial peptides and essential oils generates genuine synergy against bacterial resistance. In this article, we aim to summarize recent studies on interactions between nanoparticles and antibiotics, as well as other antibacterial agents to formulate new prospects for future studies. Based on the promising data that demonstrated the synergistic effects of antimicrobial agents with nanoparticles, we believe that this combination is a potential candidate for more research into treatments for antibiotic-resistant bacteria.

    Catfish is one of the most cultivated species worldwide. Antibiotics are usually used in catfish farming as therapeutic and prophylactic agents. In the USA, only oxytetracycline, a combination of sulfadimethoxine and ormetoprim, and florfenicol are approved by the Food Drug Administration for specific fish species (e.g., catfish and salmonids) and their specific diseases. Misuse of antibiotics as prophylactic agents in disease prevention, however, is common and contributes in the development of antibiotic resistance. Various studies had reported on antibiotic residues and/or resistance in farmed species, feral fish, water column, sediments, and, in a lesser content, among farm workers. Ninety percent of the world aquaculture production is carried out in developing countries, which lack regulations and enforcement on the use of antibiotics. Hence, efforts are needed to promote the development and enforcement of such a regulatory structure. Alternatives to antibiotics such as antibacterial vaccines, bacteriophages and their lysins, and probiotics have been applied to curtail the increasing emergence of antibiotic-resistant bacteria due to the imprudent application of antibiotics in aquaculture.

    Full Text Available Objective: The aims of this study were to identify potentially inappropriate prescribing using the Beers and STOPP criteria. The START criteria were applied to detect prescription omission in the geriatric population. We compared the utility of these criteria in institutionalised older people.Methods: Descriptive study reviewing the medication and clinical records of 81 residents (aged 65 years and more by pharmacists in a nursing home in the Lleida region (Spain.Results: The mean patients’ age was 84 (SD=8 years, with an average of 5 drugs per resident (total prescriptions: 416 medicines. The Beers criteria identified potentially inappropriate medication use in 25% of patients and 48% of patients used at least 1 inappropriate medication according to STOPP criteria. The most frequent potentially inappropriate medications for both criteria were long-acting benzodiazepines and NSAIDs. START detected 58 potential prescribing omissions in 44% of patients. Calcium-vitamin D supplementation in osteoporosis was the most frequent rule (15%, but omissions corresponding to the cardiovascular system implied 23% of patients.Conclusion: The STOPP-START criteria reveal that potentially inappropriate prescribing (PIP is a highly prevalent problem among Spanish nursing home residents, and a statistically significant positive correlation was found between the number of medicines prescribed and the number of PIP detected in this study. The STOPP criteria detect a larger number of PI medications in this geriatric population than the Beers criteria. The prescribing omissions detected by the START criteria are relevant and require intervention. Pharmacists’ review of medications may help identify potentially inappropriate prescribing and, through an interdisciplinary approach, working with physicians may improve prescribing practices among geriatric residents of nursing homes.

    caused by anaerobic bacteria and may contribute to the current literature. Because of high resistance rate detected against penicillin, this antibiotic should not be used as a first choice in empirical treatment. Cefoxitin may be used in empirical antimicrobial treatment of anaerobic gram-negatives; but the rate of antibiotic resistance should be detected for more useful and proper treatment. The prior selection of the most effective antibiotic, may contribute to decrease the rate of high resistance. In our study, no resistance was observed against carbapenem group antibiotics and metronidazole; so these antibiotics should be reserved as treatment options in the future for infections caused by resistant gram-negative anaerobic bacteria.

    Objectives To develop and apply formal ontology creation methods to the domain of antimicrobial prescribing and to formally evaluate the resulting ontology through intrinsic and extrinsic evaluation studies. Methods We extended existing ontology development methods to create the ontology and implemented the ontology using Protégé-OWL. Correctness of the ontology was assessed using a set of ontology design principles and domain expert review via the laddering technique. We created three artifacts to support the extrinsic evaluation (set of prescribing rules, alerts and an ontology-driven alert module, and a patient database) and evaluated the usefulness of the ontology for performing knowledge management tasks to maintain the ontology and for generating alerts to guide antibiotic prescribing. Results The ontology includes 199 classes, 10 properties, and 1,636 description logic restrictions. Twenty-three Semantic Web Rule Language rules were written to generate three prescribing alerts: 1) antibiotic-microorganism mismatch alert; 2) medication-allergy alert; and 3) non-recommended empiric antibiotic therapy alert. The evaluation studies confirmed the correctness of the ontology, usefulness of the ontology for representing and maintaining antimicrobial treatment knowledge rules, and usefulness of the ontology for generating alerts to provide feedback to clinicians during antibiotic prescribing. Conclusions This study contributes to the understanding of ontology development and evaluation methods and addresses one knowledge gap related to using ontologies as a clinical decision support system component—a need for formal ontology evaluation methods to measure their quality from the perspective of their intrinsic characteristics and their usefulness for specific tasks.

  4. Resource competition may lead to effective treatment of antibiotic resistant infections.

    Antonio L C Gomes

    Full Text Available Drug resistance is a common problem in the fight against infectious diseases. Recent studies have shown conditions (which we call antiR that select against resistant strains. However, no specific drug administration strategies based on this property exist yet. Here, we mathematically compare growth of resistant versus sensitive strains under different treatments (no drugs, antibiotic, and antiR, and show how a precisely timed combination of treatments may help defeat resistant strains. Our analysis is based on a previously developed model of infection and immunity in which a costly plasmid confers antibiotic resistance. As expected, antibiotic treatment increases the frequency of the resistant strain, while the plasmid cost causes a reduction of resistance in the absence of antibiotic selection. Our analysis suggests that this reduction occurs under competition for limited resources. Based on this model, we estimate treatment schedules that would lead to a complete elimination of both sensitive and resistant strains. In particular, we derive an analytical expression for the rate of resistance loss, and hence for the time necessary to turn a resistant infection into sensitive (tclear. This time depends on the experimentally measurable rates of pathogen division, growth and plasmid loss. Finally, we estimated tclear for a specific case, using available empirical data, and found that resistance may be lost up to 15 times faster under antiR treatment when compared to a no treatment regime. This strategy may be particularly suitable to treat chronic infection. Finally, our analysis suggests that accounting explicitly for a resistance-decaying rate may drastically change predicted outcomes in host-population models.

    Full Text Available Abstract Background Antibiotic misuse is widespread in resource-limited countries such as Cambodia where the burden of infectious diseases is high and access to antibiotics is unrestricted. We explored healthcare seeking behaviour related to obtaining antibiotics and drivers of antibiotic misuse in the Cambodian community. Methods In-depth interviews were held with family members of patients being admitted in hospitals and private pharmacies termed pharmacy attendants in the catchment areas of the hospitals. Nurses who run community primary healthcare centres located within the hospital catchment areas were invited to attend focus group discussions. Nvivo version 10 was used to code and manage thematic data analysis. Results We conducted individual interviews with 35 family members, 7 untrained pharmacy attendants and 3 trained pharmacists and 6 focus group discussions with 30 nurses. Self-medication with a drug-cocktail was widespread and included broad-spectrum antibiotics for mild illness. Unrestricted access to antibiotics was facilitated by various community enablers including pharmacies or drug outlets, nurse suppliers and unofficial village medical providers referred to as “village Pett” whose healthcare training has historically been in the field and not at university. These enablers supplied the community with various types of antibiotics including broad spectrum fluoroquinolones and cephalosporins. When treatment was perceived to be ineffective patients would prescriber-shop various suppliers who would unfailingly provide them with antibiotics. The main driver of the community’s demand for antibiotics was a mistaken belief in the benefits of antibiotics for a common cold, high temperature, pain, malaria and ‘Roleak’ which includes a broad catch-all for perceived inflammatory conditions. For severe illnesses, patients would attend a community healthcare centre, hospital, or when their finances permitted, a private prescriber

    To evaluate the effect of empiric antibiotics on decreasing prostate-specific antigen (PSA) levels and the possibility of avoiding unnecessary prostate biopsies (PBs). A systematic search of PubMed, Embase, and the Cochrane Library was performed to identify all randomized controlled trials (RCTs) that compared effects of empiric antibiotics with no treatment or placebo on lowering PSA levels and minimizing unnecessary PBs in patients with moderately increased PSA levels. The Cochrane Collaboration Review Manager software (RevMan 5.1.4) was used for statistical analysis. The inclusion criteria for the study were met by 6 RCTs (1 placebo controlled and 5 no treatment controlled) involving 656 patients. The synthesized data from these RCTs indicated that there were no significant differences between the antibiotic and control groups in the PSA levels after treatment (mean difference [MD] = 0.15, 95% CI:-0.50 to 0.81, P = 0.65], number of patients with decreased PSA levels after treatment (relative risk [RR] = 1.22, 95% CI: 0.90-1.65, P = 0.20], prostate-specific antigen density levels after treatment (MD =-0.04, 95% CI:-0.15 to 0.07, P = 0.47), f/t% PSA after treatment (MD =-1.47, 95% CI:-4.65 to 1.71, P = 0.37), number of patients with responsive PSA (RR = 1.02, 95% CI: 0.58-1.81, P = 0.94), and individual Pca-positiverate in these patients (RR = 1.07, 95% CI: 0.53-2.16, P = 0.86), and Pca-positiverates (RR = 0.85, 95% CI: 0.48-1.50, P = 0.57). However, the antibiotic group had a significant change in the net PSA decrease after treatment compared with the control group (MD = 1.44, 95% CI: 0.70-2.17, P = 0.0001). The use of empiric antibiotics may not significantly decrease PSA levels or avoid unnecessary PBs. Copyright © 2015 Elsevier Inc. All rights reserved.

    The author discuss the up to date interpretation of the concept of antibiotics and antibiotic research, as well as the present role of various natural, semisynthetic and synthetic antibiotic compounds in various areas of the human therapy. The origin and the total number of all antibiotics and applied antibiotics in the practice, as well as the bioactive microbial metabolites (antibiotics) in other therapeutical, non-antibiotic fields (including agriculture) are also reviewed. The author discusses main problems, such as increasing (poly)resistance, virulence of pathogens and the non-scientific factors (such as a decline of research efforts and their sociological, economic, financial and regulatory reasons). A short summary of the history of Hungarian antibiotic research is also provided. The author briefly discusses the prospects in the future and the general advantages of the natural products over synthetic compounds. It is concluded that new approaches for the investigation of the unlimited possibilities of the living world are necessary. The discovery of new types or simply neglected (micro)organisms and their biosynthetic capabilities, the introduction of new biotechnological and genetic methods (genomics, metagenom, genome mining) are absolutely required in the future.

    Antibiotic-resistant bacteria were first identified in the 1940s, but while new antibiotics were being discovered at a steady rate, the consequences of this phenomenon were slow to be appreciated. Today, the excessive use of antibiotics compounded by the paucity of new agents on the market has...... meant the problem of antibiotic resistance is fast escalating into a global health crisis. There is no doubt that misuse of these drugs in human beings has contributed to the increasing rates of resistance, but recently the use of antibiotics in food animals and its consequent effect on resistance....... There is a growing concern over the transmission of resistant bacteria via the food chain. Many questions will be difficult to resolve, such as how do you distinguish the fraction of resistance in human beings that originated from animals? If we wait to see evidence that a significant amount of antibiotic resistance...

  10. Phenotype overlap in Xylella fastidiosa is controlled by the cyclic di-GMP phosphodiesterase Eal in response to antibiotic exposure and diffusible signal factor-mediated cell-cell signaling.

    Eal is an EAL domain protein in Xylella fastidiosa homologous to one involved in resistance to tobramycin in Pseudomonas aeruginosa. EAL and HD-GYP domain proteins are implicated in the hydrolysis of the secondary messenger bis-(3'-5')-cyclic dimeric GMP (cyclic di-GMP). Cell density-dependent communication mediated by a Diffusible Signal Factor (DSF) also modulates cyclic di-GMP levels in X. fastidiosa, thereby controlling the expression of virulence genes and genes involved in insect transmission. The possible linkage of Eal to both extrinsic factors such as antibiotics and intrinsic factors such as quorum sensing, and whether both affect virulence, was thus addressed. Expression of eal was induced by subinhibitory concentrations of tobramycin, and an eal deletion mutant was more susceptible to this antibiotic than the wild-type strain and exhibited phenotypes similar to those of an rpfF deletion mutant blocked in DSF production, such as hypermotility, reduced biofilm formation, and hypervirulence to grape. Consistent with that, the rpfF mutant was more susceptible than the wild-type strain to tobramycin. Therefore, we propose that cell-cell communication and antibiotic stress can apparently lead to similar modulations of cyclic di-GMP in X. fastidiosa, resulting in similar phenotypes. However, the effect of cell density is dominant compared to that of antibiotic stress, since eal is suppressed by RpfF, which may prevent inappropriate behavioral changes in response to antibiotic stress when DSF accumulates.

    To probe the overflow pollution of separate storm drains with inappropriate sewage entries, in terms of the relationship between sewage entries and the corresponding dry-weather and wet-weather overflow, the monitoring activities were conducted in a storm drainage system in the Shanghai downtown area (374 ha). In this study site, samples from inappropriately entered dry-weather sewage and the overflow due to storm pumps operation on dry-weather and wet-weather days were collected and then monitored for six water quality constituents. It was found that overflow concentrations of dry-weather period could be higher than those of wet-weather period; under wet-weather period, the overflow concentrations of storm drains were close to or even higher than that of combined sewers. Relatively strong first flush mostly occurred under heavy rain that satisfied critical rainfall amount, maximum rainfall intensity, and maximum pumping discharge, while almost no first flush effect or only weak first flush effect was found for the other rainfall events. Such phenomenon was attributed to lower in-line pipe storage as compared to that of the combined sewers, and serious sediment accumulation within the storm pipes due to sewage entry. For this kind of system, treating a continuous overflow rate is a better strategy than treating the maximum amount of early part of the overflow. Correcting the key inappropriate sewage entries into storm drains should also be focused.

    2017-07-10

    Community acquired pneumonia remains a common cause of morbidity and mortality. Usually, the causal organism is not identified and treatment remains empiric. Recent computed tomography and magnetic resonance imaging studies have challenged the accuracy of the clinical diagnosis of pneumonia, and epidemiologic studies are changing our perspective of what causes community acquired pneumonia, especially the role of viral pathogens and the frequent finding of multiple pathogens. The past decade has seen increasing overuse of empiric coverage of meticillin resistant Staphylococcus aureus and antibiotic resistant Gram negative pathogens owing to inappropriate application of guidelines for healthcare associated pneumonia. Optimal treatment remains a matter for debate, especially in very sick patients, including the role of combination antibiotic therapy and corticosteroids. Pneumonia care bundles are being defined to improve outcomes. Increased recognition of both acute and long term cardiac complications is shifting our concept of pneumonia from an acute lung disease to a multisystem problem with adverse chronic health consequences.

    Full Text Available Aim Urinary tract infection is one of the most common serious bacterial infections in children. Due to regional differences and past infections, the use of antibiotics has problems such as variability in microorganisms and antibiotic susceptibility. In this study, we aimed to determine the microorganisms detected in urinary tract infections in children and their antibiotic resistance status.Methods A retrospective observational study was planned. Demographic data, urine microscopy and urine culture results of patients who were hospitalized with urinary tract infection diagnosis in our pediatric clinic at hospital were recorded retrospectively through hospital automation system. The first culture results of the patients were used in the evaluation of the data. Results In the study group of 112 patients, Escherichia coli (E. coli and Klebsiella were the most identified microorganisms in patients with urinary culture. Under 2 years old, Klebsiella was more frequent, and at 2 years of age there was a noticeable increase in the frequency of E-coli. The most common resistance of both microorganisms was found to be ampicillin. Conclusions: Regional infectious agents and antibiotic resistance should be revised at regular intervals, appropriate empiric therapy should be considered. Thus, is predicted that the chance of success in treatment will increase and the speed of resistance development will decrease.

    The use of prophylactic antibiotics in clean operations was routine in China before 2011. Along with the appeal for using antibiotics rationally by WHO in 2011, China launched a national special rectification scheme on clinical use of antibiotics from April that year. The scheme, aimed at achieving rational use of antibiotics, made pharmacists part of the responsible medical team. Our objective was to describe the impacts of pharmacist intervention on the use of antibiotics, particularly in urology clean operations. Pharmacists participated in antibiotic stewardship programmes of the hospital and urological clinical work and conducted real-time interventions at the same time from 2011 to 2013. Data on the use of antibiotics between 2010 and 2013 in urology were collected. Comparison of the 2013 data with those of 2010 showed that antibiotic use density [AUD= DDDs*100/(The number of patients who were treated the same period*Average days in hospital). DDDs = Total drug consumption (g)/DDD. DDD is the Defined Daily Dose] decreased by 57·8(58·8%); average antibiotic cost decreased by 246·94 dollars; the cost of antibiotics as a percentage of total drug cost decreased by 27·7%; the rate of use of antibiotics decreased from 100% to 7·3%. The study illustrates how an antibiotic stewardship programme with pharmacist participation including real-time interventions can promote improved antibiotic-prescribing and significantly decrease costs. © 2015 John Wiley & Sons Ltd.

    Full Text Available Abstract Background Studies indicate that antibiotics are sold against regulation and without prescription in private drugstores in rural Tanzania. The objective of the study was to explore and describe antibiotics sale and dispensing practices and link it to drugseller knowledge and perceptions of antibiotics and antibiotic resistance. Methods Exit customers of private drugstores in eight districts were interviewed about the drugstore encounter and drugs bought. Drugsellers filled in a questionnaire with closed- and open-ended questions about antibiotics and resistance. Data were analyzed using mixed quantitative and qualitative methods. Results Of 350 interviewed exit customers, 24% had bought antibiotics. Thirty percent had seen a health worker before coming and almost all of these had a prescription. Antibiotics were dispensed mainly for cough, stomachache, genital complaints and diarrhea but not for malaria or headache. Dispensed drugs were assessed as relevant for the symptoms or disease presented in 83% of all cases and 51% for antibiotics specifically. Non-prescribed drugs were assessed as more relevant than the prescribed. The knowledge level of the drugseller was ranked as high or very high by 75% of the respondents. Seventy-five drugsellers from three districts participated. Seventy-nine percent stated that diseases caused by bacteria can be treated with antibiotics but 24% of these also said that antibiotics can be used for treating viral disease. Most (85% said that STI can be treated with antibiotics while 1% said the same about headache, 4% general weakness and 3% 'all diseases'. Seventy-two percent had heard of antibiotic resistance. When describing what an antibiotic is, the respondents used six different kinds of keywords. Descriptions of what antibiotic resistance is and how it occurs were quite rational from a biomedical point of view with some exceptions. They gave rise to five categories and one theme: Perceiving antibiotic

    Full Text Available Abstract Background Currently ambulatory patients break one in four tablets before ingestion. Roughly 10% of them are not suitable for splitting because they lack score lines or because enteric or modified release coating is destroyed impairing safety and effectiveness of the medication. We assessed impact and safety of computerised decision support on the inappropriate prescription of split tablets. Methods We performed a prospective intervention study in a 1680-bed university hospital. Over a 15-week period we evaluated all electronically composed medication regimens and determined the fraction of tablets and capsules that demanded inappropriate splitting. In a subsequent intervention phase of 15 weeks duration for 10553 oral drugs divisibility characteristics were indicated in the system. In addition, an alert was generated and displayed during the prescription process whenever the entered dosage regimen demanded inappropriate splitting (splitting of capsules, unscored tablets, or scored tablets unsuitable for the intended fragmentation. Results During the baseline period 12.5% of all drugs required splitting and 2.7% of all drugs (257/9545 required inappropriate splitting. During the intervention period the frequency of inappropriate splitting was significantly reduced (1.4% of all drugs (146/10486; p = 0.0008. In response to half of the alerts (69/136 physicians adjusted the medication regimen. In the other half (67/136 no corrections were made although a switch to more suitable drugs (scored tablets, tablets with lower strength, liquid formulation was possible in 82% (55/67. Conclusion This study revealed that computerised decision support can immediately reduce the frequency of inappropriate splitting without introducing new safety hazards.

  1. Environmental dissemination of antibiotic resistance genes and correlation to anthropogenic contamination with antibiotics

    2015-01-01

    Antibiotic resistance is a growing problem which threatens modern healthcare globally. Resistance has traditionally been viewed as a clinical problem, but recently non-clinical environments have been highlighted as an important factor in the dissemination of antibiotic resistance genes (ARGs). Horizontal gene transfer (HGT) events are likely to be common in aquatic environments; integrons in particular are well suited for mediating environmental dissemination of ARGs. A growing body of evidence suggests that ARGs are ubiquitous in natural environments. Particularly, elevated levels of ARGs and integrons in aquatic environments are correlated to proximity to anthropogenic activities. The source of this increase is likely to be routine discharge of antibiotics and resistance genes, for example, via wastewater or run-off from livestock facilities and agriculture. While very high levels of antibiotic contamination are likely to select for resistant bacteria directly, the role of sub-inhibitory concentrations of antibiotics in environmental antibiotic resistance dissemination remains unclear. In vitro studies have shown that low levels of antibiotics can select for resistant mutants and also facilitate HGT, indicating the need for caution. Overall, it is becoming increasingly clear that the environment plays an important role in dissemination of antibiotic resistance; further studies are needed to elucidate key aspects of this process. Importantly, the levels of environmental antibiotic contamination at which resistant bacteria are selected for and HGT is facilitated at should be determined. This would enable better risk analyses and facilitate measures for preventing dissemination and development of antibiotic resistance in the environment. PMID:26356096

    The efficacy of oral urea in producing a sufficiently high osmotic diuresis was tested in seven patients with the syndrome of inappropriate secretion of antidiuretic hormone. In all patients urea corrected the hyponatraemia despite a normal fluid intake. Five patients were controlled (serum sodium concentration greater than 128 mmol(mEq)/1) with a dose of 30 g urea daily, and two with 60 g daily. The patients who needed 30 g drank 1-2 1 of fluid daily, while those who needed 60 g drank up to 3.1 per day. No major side effects were noted, even after treatment periods of up to 270 days. These findings suggest that urea is a safe and efficacious treatment of the syndrome of inappropriate secretion of antidiuretic hormone.

    Antimicrobial stewardship can be challenging in children with bloodstream infections (BSIs) caused by Gram-negative bacilli (GNB). This retrospective cohort study explored how data elements in the electronic health record could potentially optimize empiric antibiotic therapy for BSIs caused by GNB, via the construction of customized antibiograms for categorical GNB infections and identification of opportunities to minimize organism-drug mismatch and decrease time to effective therapy. Our results suggest potential strategies that could be implemented at key decision points in prescribing at initiation, modification, and targeting of therapy.

    To determine whether the use of information technology (IT), measured by Meaningful Use capability, is associated with lower rates of inappropriate utilization of imaging services in hospital outpatient settings. A retrospective cross-sectional analysis of 3332 nonfederal U.S. hospitals using data from: Hospital Compare (2011 outpatient imaging efficiency measures), HIMSS Analytics (2009 health IT), and Health Indicator Warehouse (market characteristics). Hospitals were categorized for their health IT infrastructure including EHR Stage-1 capability, and three advanced imaging functionalities/systems including integrated picture archiving and communication system, Web-based image distribution, and clinical decision support (CDS) with physician pathways. Three imaging efficiency measures suggesting inappropriate utilization during 2011 included: percentage of "combined" (with and without contrast) computed tomography (CT) studies out of all CT studies for abdomen and chest respectively, and percentage of magnetic resonance imaging (MRI) studies of lumbar spine without antecedent conservative therapy within 60days. For each measure, three separate regression models (GLM with gamma-log link function, and denominator of imaging measure as exposure) were estimated adjusting for hospital characteristics, market characteristics, and state fixed effects. Additionally, Heckman's Inverse Mills Ratio and propensity for Stage-1 EHR capability were used to account for selection bias. We find support for association of each of the four health IT capabilities with inappropriate utilization rates of one or more imaging modality. Stage-1 EHR capability is associated with lower inappropriate utilization rates for chest CT (incidence rate ratio IRR=0.72, p-value value value value value value value use of Stage-1 Meaningful Use capable EHR systems along with advanced imaging related functionalities could have a beneficial impact on reducing some of the inappropriate utilization of

  5. The future of antibiotics

    2014-01-01

    Antibiotic resistance continues to spread even as society is experiencing a market failure of new antibiotic research and development (R&D). Scientific, economic, and regulatory barriers all contribute to the antibiotic market failure. Scientific solutions to rekindle R&D include finding new screening strategies to identify novel antibiotic scaffolds and transforming the way we think about treating infections, such that the goal is to disarm the pathogen without killing it or modulate the host response to the organism without targeting the organism for destruction. Future economic strategies are likely to focus on ‘push’ incentives offered by public-private partnerships as well as increasing pricing by focusing development on areas of high unmet need. Such strategies can also help protect new antibiotics from overuse after marketing. Regulatory reform is needed to re-establish feasible and meaningful traditional antibiotic pathways, to create novel limited-use pathways that focus on highly resistant infections, and to harmonize regulatory standards across nations. We need new antibiotics with which to treat our patients. But we also need to protect those new antibiotics from misuse when they become available. If we want to break the cycle of resistance and change the current landscape, disruptive approaches that challenge long-standing dogma will be needed. PMID:25043962

    Antimicrobial and antibiotics resistance caused by misuse or overuse of antibiotics exposure is a growing and significant threat to global public health. The spread and horizontal transfer of antibiotic resistant bacteria (ARB) and antibiotic resistance genes (ARGs) by the selective pressure of antibiotics in an aquatic environment is a major public health issue. To develop a better understanding of potential ecological risks die to antibiotics and ARGs, this study mainly summarizes research progress about: (i) the occurrence, concentration, fate, and potential ecological effects of antibiotics and ARGs in various aquatic environments, (ii) the threat, spread, and horizontal gene transfer (HGT) of ARGs, and (iii) the relationship between antibiotics, ARGs, and ARB. Finally, this review also proposes future research direction on antibiotics and ARGs.

    2017-06-01

    This paper designs a bio-economic model to examine the use of substitute antibiotic drugs (analogs) sold by an industry that has open access to the resource of the antibiotic class's susceptibility (treatment effectiveness). Antibiotics are characterized by different expected recovery rates and production costs, which in conjunction with the class's treatment susceptibility determines their relative effectiveness. Our analysis reveals that the high-quality antibiotic drug loses its comparative advantage over time making the low-quality drug the treatment of last resort in the market equilibrium and the social optimum when antibiotic susceptibility cannot replenish. However, when antibiotic susceptibility is renewable, both antibiotics may be used in the long run, and the comparative advantage of the high-quality drug may be restored in the social optimum that allows lowering infection in the long run. We develop the optimal tax/subsidy scheme that would induce antibiotic producers under open access to behave optimally and account for the social cost of infection and value of antibiotic susceptibility. We show that the welfare loss associated with the uncorrected open-access allocation is highest; when the resource of antibiotic susceptibility is non-renewable, high morbidity costs are incurred by individuals, and low social discount rates apply.

    Full Text Available Summary: Antimicrobial resistance in bacterial pathogens is a challenge that is associated with high morbidity and mortality. Multidrug resistance patterns in Gram-positive and -negative bacteria are difficult to treat and may even be untreatable with conventional antibiotics. There is currently a shortage of effective therapies, lack of successful prevention measures, and only a few new antibiotics, which require development of novel treatment options and alternative antimicrobial therapies. Biofilms are involved in multidrug resistance and can present challenges for infection control. Virulence, Staphylococcus aureus, Clostridium difficile infection, vancomycin-resistant enterococci, and control in the Emergency Department are also discussed.

    2014-01-01

    Glycopeptides such as vancomycin, teicoplanin and telavancin are essential for treating infections caused by Gram-positive bacteria. Unfortunately, the dwindled pipeline of new antibiotics into the market and the emergence of glycopeptide-resistant enterococci and other resistant bacteria are increasingly making effective antibiotic treatment difficult. We have now learned a great deal about how bacteria produce antibiotics. This information can be exploited to develop the next generation of antimicrobials. The biosynthesis of glycopeptides via nonribosomal peptide assembly and unusual amino acid synthesis, crosslinking and tailoring enzymes gives rise to intricate chemical structures that target the bacterial cell wall. This review seeks to describe recent advances in our understanding of both biosynthesis and resistance of these important antibiotics.

    For thousands of years people were delivered helplessly to various kinds of infections, which often reached epidemic proportions and have cost the lives of millions of people. This is precisely the age since mankind has been thinking of infectious diseases and the question of their causes. However, due to a lack of knowledge, the search for strategies to fight, heal, and prevent the spread of communicable diseases was unsuccessful for a long time. It was not until the discovery of the healing effects of (antibiotic producing) molds, the first microscopic observations of microorganisms in the seventeenth century, the refutation of the abiogenesis theory, and the dissolution of the question "What is the nature of infectious diseases?" that the first milestones within the history of antibiotics research were set. Then new discoveries accelerated rapidly: Bacteria could be isolated and cultured and were identified as possible agents of diseases as well as producers of bioactive metabolites. At the same time the first synthetic antibiotics were developed and shortly thereafter, thousands of synthetic substances as well as millions of soil borne bacteria and fungi were screened for bioactivity within numerous microbial laboratories of pharmaceutical companies. New antibiotic classes with different targets were discovered as on assembly line production. With the beginning of the twentieth century, many of the diseases which reached epidemic proportions at the time-e.g., cholera, syphilis, plague, tuberculosis, or typhoid fever, just to name a few, could be combatted with new discovered antibiotics. It should be considered that hundred years ago the market launch of new antibiotics was significantly faster and less complicated than today (where it takes 10-12 years in average between the discovery of a new antibiotic until the launch). After the first euphoria it was quickly realized that bacteria are able to develop, acquire, and spread numerous resistance mechanisms

    To curtail inappropriate plasma transfusions, we instituted clinical decision support as an alert upon order entry if the patient's recent international normalized ratio (INR) was 1.7 or less. The alert was suppressed for massive transfusion and within operative or apheresis settings. The plasma order was automatically removed upon alert acceptance while clinical exception reasons allowed for continued transfusion. Alert impact was studied comparing a 7-month control period with a 4-month intervention period. Monthly plasma utilization decreased 17.4%, from a mean ± SD of 3.40 ± 0.48 to 2.82 ± 0.6 plasma units per hundred patient days (95% confidence interval [CI] of difference, -0.1 to 1.3). Plasma transfused below an INR of 1.7 or less decreased from 47.6% to 41.6% (P = .0002; odds ratio, 0.78; 95% CI, 0.69-0.89). The alert recommendation was accepted 33% of the time while clinical exceptions were chosen in the remaining cases (active bleeding, 31%; other clinical indication, 33%; and apheresis, 2%). Alert acceptance rate varied significantly among different provider specialties. Clinical decision support can help curtail inappropriate plasma use but needs to be part of a comprehensive strategy including audit and feedback for comprehensive, long-term changes. © American Society for Clinical Pathology, 2017.

    One of the causes of preventable adverse drug events (ADES) in older patients constitutes inappropriate prescription of drugs (PIM). The PIM is where risks exceed the clinical benefit. Several instruments can be use to measure this problem, the most used are: a) Beers criteria; b) Screening tool to Older People Potentially inappropriate Prescription (STOPP); c) Screening tool to Alert Doctors to Right Appropriate indicated Treatments (START); d) The Medication Appropriateness Index (MAI). This study aims to assess the prevalence of PIM, in a population of older adults in three clinical scopes of university hospital. cross sectional study of 300 cases from a random sample of fields: hospitalization (n=100), ambulatory (n=100) and emergency (n=100), all patients over 65 years old or more who where treated at our hospital. 1355 prescription drugs were analized, finding patients hospitalized (PIM) of 57.7%, 55%, 26%, and 80% according to Beers, in ambulatory 36%, 36.5%, 5% and 52% with the same tools and in emergency 35%, 35%, 6% y 52% with the same tools. Was found significant association the PIM with polipharmacy with Beers, STOPP and MAI. results can be compare to world literature (26-80% vs 11-73.1%). The STOPP-START used in an integrated manner would be best estimating the problem of PIM. Copyright © 2016 SECA. Publicado por Elsevier España, S.L.U. All rights reserved.

  15. Inappropriate emergency laboratory test ordering: defensive or peer evidence shared based medicine?

    Full Text Available BACKGROUND The laboratory overuse is widely prevalent in hospital practice, mostly in the emergency care. Reasons for excessive and inappropriate test-ordering include defensive behaviour and fear or uncertainty, lack of experience, the misuse of protocols and guidelines, “routine” and local attitudes, inadequate educational feedback and clinician’s unawareness about the cost of examinations and their related implications. AIM OF THE STUDY AND METHODS The primary target of our working group was to reduce inappropriate ordering on a urgent basis test, implementing further examinations not yet previewed in the hospital panel of the available urgencies, according to the evidence based diagnosis concept. The secondary goal was to indicate strategies of re-engineering of the processes, improving turnaround time in the laboratory management of emergencies. After evaluating, as first intervention, the more reliable sources for practice guidelines, systematic reviews and RCTs, the committee further discussed main topics with in-hospital stakeholders, selected from Emergency, Internal Medicine and Surgery Depts. The working group, in many subsequent audits, tried to obtain a systematic feed back with all involved professionals. RESULTS After reviewing literature’s evidence, the board constrained testing options by defining the basic emergency laboratory panel tests (blood type, hemogram, blood urea nitrogen, plasma creatinine, glucose, sodium, potassium, chloride, osmolarity, CRP, bicarbonate, CPK, creatine phosphokinase-MB, myoglobin, troponin, BNP and NT-proBNP, PT-INR, PTT, D-dimer, beta- HCG, biochemical urinalysis etc.. As final result, the proposed tests reduced the overall number of inappropriate investigations and increased, with newer and updated tests, the available panel for critical patients.

    Inappropriate antibiotic prescribing, particularly for respiratory tract infections (RTI) in ambulatory care, has become a worldwide public health threat due to resulting antibiotic resistance. In spite of various interventions and campaigns, wide variations in antibiotic use persist between European countries. Cultural determinants are often referred to as a potential cause, but are rarely defined. To our knowledge, so far no systematic literature review has focused on cultural determinants of antibiotic use. The aim of this study was to identify cultural determinants, on a country-specific level in ambulatory care in Europe, and to describe the influence of culture on antibiotic use, using a framework of cultural dimensions. A computer-based systematic literature review was conducted by two research teams, in France and in Norway. Eligible publications included studies exploring antibiotic use in primary care in at least two European countries based on primary study results, featuring a description of cultural determinants, and published between 1997 and 2015. Quality assessment was conducted independently by two researchers, one in each team, using appropriate checklists according to study design. Each included paper was characterized according to method, countries involved, sampling and main results, and cultural determinants mentioned in each selected paper were extracted, described and categorized. Finally, the influence of Hofstede's cultural dimensions associated with antibiotic consumption within a primary care setting was described. Among 24 eligible papers, 11 were rejected according to exclusion criteria. Overall, 13 papers meeting the quality assessment criteria were included, of which 11 used quantitative methods and two qualitative or mixed methods. The study participants were patients (nine studies) and general practitioners (two studies). This literature review identified various cultural determinants either patient-related (illness perception

  17. On the local applications of antibiotics and antibiotic-based agents in endodontics and dental traumatology.

    Antibiotics are a valuable adjunctive to the armamentarium available to health professionals for the management of bacterial infections. During endodontic treatment and when managing trauma to the teeth, antibiotics may be applied systemically (orally and/or parenterally) or locally (i.e. intra-dentally via irrigants and medicaments). Due to the potential risk of adverse effects following systemic application, and the ineffectiveness of systemic antibiotics in necrotic pulpless teeth and the periradicular tissues, the local application of antibiotics may be a more effective mode for delivery in endodontics. The aim of this article was to review the history, rationale and applications of antibiotic-containing irrigants and medicaments in endodontics and dental traumatology. The search was performed from 1981 to 2008 and was limited to English-language papers. The keywords searched on Medline were 'Antibiotics AND endodontics', 'Antibiotics AND root canal irrigation', 'Antibiotics AND intra-canal medicament', 'Antibiotics AND Dental trauma' and 'Antibiotics AND root resorption'. The reference section of each article was manually searched to find other suitable sources of information. It seems that local routes of antibiotic administration are a more effective mode than systemic applications. Various antibiotics have been tested in numerous studies and each has some advantages. Tetracyclines are a group of bacteriostatic antibiotics with antibacterial substantivity for up to 12 weeks. They are typically used in conjunction with corticosteroids and these combinations have anti-inflammatory, anti-bacterial and anti-resorptive properties, all of which help to reduce the periapical inflammatory reaction including clastic-cell mediated resorption. Tetracyclines have also been used as part of irrigating solutions but the substantivity is only for 4 weeks. Clindamycin and a combination of three antibiotics (metronidazole, ciprofloxacin and minocycline) have also been

    This project aims to study the use of antibiotics in three clinical wards in the largest tertiary teaching hospital in Ethiopia for a period of 1 year. The specific aims were to assess the prevalence of patients on antibiotics, quantify the antibiotic consumption and identify the main indications of use. The material was all the medical charts (n = 2231) retrieved from three clinical wards (internal medicine, gynecology/obstetrics and surgery) in Tikur Anbessa Specialized Hospital (TASH) in Addis Ababa between September 2013 and September 2014. Data collection was performed manually by four pharmacists. Each medical chart represented one patient. About 60% of the patients were admitted to internal medicine, 20% to each of the other two wards. The number of bed days (BD) was on average 16.5. Antibiotics for systemic use were prescribed to 73.7% of the patients (on average: 2.1 antibiotics/patient) of whom 86.6% got a third or fourth generation cephalosporin (mainly ceftriaxone). The average consumption of antibiotics was 81.6 DDD/100BD, varying from 91.8 in internal medicine and 71.6 in surgery to 47.6 in gynecology/obstetrics. The five most frequently occurring infections were pneumonia (26.6%), surgical site infections (21.5%), neutropenic fever (6.9%), sepsis (6.4%) and urinary tract infections (4.7%). About one fourth of the prescriptions were for prophylactic purposes. Hospital acquired infections occurred in 23.5% of the patients (353 cases of surgical site infection). The prescribing was based on empirical treatment and sensitivity testing was reported in only 3.8% of the cases. In the present study from three wards in the largest tertiary teaching hospital in Ethiopia, three out of four patients were prescribed antibiotics, primarily empirically. The mean antibiotic consumption was 81.6 DDD/100BD. Surgical site infections constituted a large burden of the infections treated in the hospital, despite extensive prescribing of prophylaxis. The findings show

    The main goal of this study was to determine the in vitro susceptibility of strains collected from marketed probiotics to antibiotics used to treat community-acquired infections. The minimum inhibitory concentrations (MICs) of 16 antibiotics were determined using a gradient strip (E test) or the agar dilution method for fidaxomicin. The probiotics demonstrated various antibiotic patterns. Bacterial probiotics are generally susceptible to most prescribed antibiotics orally administered, whereas yeast probiotics, such as Saccharomyces boulardii, are resistant. Special attention must be paid to co-prescriptions of antibiotics and probiotics to ensure that the probiotic strain is not susceptible. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

    This study aimed to evaluate antibiotic resistance in the province of Şanliurfa and to observe any difference between antibiotic resistance rates. The study comprised 107 children who presented at the pediatric polyclinic with complaints of urinary tract infection with the diagnosis of urinary tract infection and whose urine cultures exhibited bacterial growth. The patients were analyzed with respect to the frequency of proliferating pathogens, sensitivity to the antibiotics used and the rates of developed resistance to the antibiotics. A total of 107 patients aged between 1 year and 15 years were included in the study, encompassing 14 (13.1%) males and 93 (86.9%) females. According to the urine culture results, proliferation of Escherichia coli (E. coli) was observed in 69 (64.5%), Klebsiella spp. in 13 (12.1%), Proteus mirabilis in 9 (8.4%), Staphylococcus aureus in 5 (4.7%), Pseudomonas aeruginosa in 5 (4.7%), Acinetobacter spp. in 3 (2.8%) and Enterococcus spp. in 3 (2.8%) patients. For proliferating E. coli, high resistance rates to ceftriaxone (39.5%), nitrofurantoin (19.7%), ampicillin-sulbactam (64.1%), co-trimoxazole (41.5%), amoxicillinclavulanate (51.7%) and cefuroxime (38.1%) were observed. All of isolated microorganisms were resistant to ampicillin-sulbactam, amoxicillin-clavulanate, co-trimoxazole, ceftriaxone, cefuroxime and cefoxitin in decreasing frequencies. The most effective antimicrobial agents were determined to be imipenem, sulpera-zone, quinolone and aminoglycosides. In our region, parenteral antibiotics that should be selected for the empirical treatment of UTIs in all age groups are the aminoglycosides and 3(rd) generation cephalosporines. In contrast to other studies, these results suggest that co-trimoxazole should be used for children aged 0-1, and 2(nd) generation cephalosporins should be used for the oral treatment of children aged 1-5 due to the low rate of resistance to nitrofurantoin in patients aged over 5 years.

    Association between previous antibiotic use and emergence of antibiotic resistance has been reported for several microorganisms. The relationship has been extensively studied, and although the causes of antibiotic resistance are multi-factorial, clear evidence of antibiotic use as a major risk factor exists. Most studies are carried out in countries with high consumption of antibiotics and corresponding high levels of antibiotic resistance, and currently, little is known whether and at what level the associations are detectable in a low antibiotic consumption environment. We conduct an ecological, retrospective study aimed at determining the impact of antibiotic consumption on antibiotic-resistant Pseudomonas aeruginosa in three hospitals in Norway, a country with low levels of antibiotic use. We construct a sophisticated statistical model to capture such low signals. To reduce noise, we conduct our study at hospital ward level. We propose a random effect Poisson or binomial regression model, with a reparametrisation that allows us to reduce the number of parameters. Inference is likelihood based. Through scenario simulation, we study the potential effects of reduced or increased antibiotic use. Results clearly indicate that the effects of consumption on resistance are present under conditions with relatively low use of antibiotic agents. This strengthens the recommendation on prudent use of antibiotics, even when consumption is relatively low. Copyright © 2012 John Wiley & Sons, Ltd.

    Full Text Available Abstract Background Research has shown that a number of patients, with a variety of diagnoses, are admitted to hospital when it is not essential and can remain in hospital unnecessarily. To date, research in this area has been primarily quantitative. The purpose of this study was to explore the perceived causes of inappropriate or prolonged lengths of stay and focuses on a specific population (i.e., patients with long term neurological conditions. We also wanted to identify interventions which might avoid admission or expedite discharge as periods of hospitalisation pose particular risks for this group. Methods Two focus groups were conducted with a convenience sample of eight primary and secondary care clinicians working in the Derbyshire area. Data were analysed using a thematic content approach. Results The participants identified a number of key causes of inappropriate admissions and lengths of stay, including: the limited capacity of health and social care resources; poor communication between primary and secondary care clinicians and the cautiousness of clinicians who manage patients in community settings. The participants also suggested a number of strategies that may prevent inappropriate admissions or reduce length of stay (LoS, including: the introduction of new sub-acute care facilities; the introduction of auxiliary nurses to support specialist nursing staff and patient held summaries of specialist consultations. Conclusion Clinicians in both the secondary and primary care sectors acknowledged that some admissions were unnecessary and some patients remain in hospital for a prolonged period. These events were attributed to problems with the current capacity or structuring of services. It was noted, for example, that there is a shortage of appropriate therapeutic services and that the distribution of beds between community and sub-acute care should be reviewed.

    The proximal femuris is an uncommon site of osteosarcoma. The unusual manifestations at this site may lead to diagnostic and therapeutic mistakes. We therefore performed a retrospective study to estimate the proportions of patients with imaging study findings and/or clinical manifestations typical for osteosarcoma and/or inappropriate treatment decisions. Proximal femoral osteosarcoma often produces atypical clinical and radiological presentations. Consecutive patients who underwent surgery at our center to treat proximal femoral osteosarcoma were included. For each patient, we collected the epidemiological characteristics, clinical symptoms, imaging study findings, treatment, and tumor outcome. Proportions were computed with their confidence intervals. Twelve patients had surgery for proximal femoral osteosarcoma between 1986 and 2015. Imaging findings were typical in 1 (8%) patient; they consisted of ill-defined osteolysis in 11/12 (92%) patients, a periosteal reaction in 1/12 (8%) patient, soft tissue involvement in 7/12 (58%) patients, and immature osteoid matrix in 11/12 (92%) patients. No patient had the typical combination of pain with a soft tissue swelling. Management was inappropriate in 2/12 (17%) patients, who did not undergo all the recommended imaging studies before surgery and were treated in another center before the correct diagnosis was established. At last follow-up, 4 patients had died (after a mean of 7 years) and 8 were alive (after a mean of 4 years). Proximal femoral osteosarcoma is uncommon and rarely produces the typical clinical and imaging study findings. The atypical presentation often results in diagnostic errors and inappropriate treatments. Ill-defined osteolysis on standard radiographs should prompt computed tomography or magnetic resonance imaging of the proximal femur. Treatment in a specialized center is imperative.

    Full Text Available Antibiotic resistance genes (ARGs have been commonly reported due to the overuse worldwide of antibiotics. Antibiotic overuse disturbs the environment and threatens public human health. The objective of this study was to measure the residual concentrations of veterinary antibiotics in the tetracycline group (TCs, including tetracycline (TC and chlortetracycline (CTC, as well as those in the sulfonamide group (SAs, including sulfamethazine (SMT, sulfamethoxazole (SMX, and sulfathiazole (STZ. We also isolated the corresponding ARGs in the agroecosystem. Four sediment samples and two rice paddy soil samples were collected from sites near a swine composting facility along the Naerincheon River in Hongcheon, Korea. High performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS was employed with a solid-phase extraction method to measure the concentration of each antibiotic. ARGs were identified by the qualitative polymerase chain-reaction using synthetic primers. SAs and their corresponding ARGs were highly detected in sediment samples whereas TCs were not detected except for sediments sample #1. ARGs for TCs and SAs were detected in rice paddy soils, while ARGs for TCs were only found in sediment #2 and #4. Continuous monitoring of antibiotic residue and its comprehensive impact on the environment is needed to ensure environmental health.

    Antibiotics are by far the most common medications prescribed for children. Recent epidemiological data suggests an association between early antibiotic use and disease phenotypes in adulthood. Antibiotic use during infancy induces imbalances in gut microbiota, called dysbiosis. The gut microbiome's responses to antibiotics and its potential link to disease development are especially complex to study in the changing infant gut. Here, we synthesize current knowledge linking antibiotics, dysbiosis, and disease and propose a framework for studying antibiotic-related dysbiosis in children. We recommend future studies into the microbiome-mediated effects of antibiotics focused on four types of dysbiosis: loss of keystone taxa, loss of diversity, shifts in metabolic capacity, and blooms of pathogens. Establishment of a large and diverse baseline cohort to define healthy infant microbiome development is essential to advancing diagnosis, interpretation, and eventual treatment of pediatric dysbiosis. This approach will also help provide evidence-based recommendations for antibiotic usage in infancy. Copyright © 2015 Elsevier Inc. All rights reserved.

    The widespread use of antibiotics has led to the evolution of resistance in bacteria. Bacteria can gain resistance to the antibiotic ampicillin by acquiring a plasmid carrying the gene beta-lactamase, which inactivates the antibiotic. This inactivation may represent a cooperative behavior, as the entire bacterial population benefits from removing the antibiotic. The cooperative nature of this growth suggests that a cheater strain---which does not contribute to breaking down the antibiotic---may be able to take advantage of cells cooperatively inactivating the antibiotic. Here we find experimentally that a ``sensitive'' bacterial strain lacking the plasmid conferring resistance can invade a population of resistant bacteria, even in antibiotic concentrations that should kill the sensitive strain. We observe stable coexistence between the two strains and find that a simple model successfully explains the behavior as a function of antibiotic concentration and cell density. We anticipate that our results will provide insight into the evolutionary origin of phenotypic diversity and cooperative behaviors.

    Urinary tract infection (UTI) is one of the most common bacterial infections in childhood and causes acute and chronic morbidity and long-term hypertension and chronic kidney disease. To describe the demographic characteristics, infectious agents, patterns of antibiotic resistance, etiologic agent and profile of susceptibility and response to empirical treatment of UTI in a pediatric population. This is a descriptive, retrospective study. Included in the study were 144 patients, 1:2.06 male to female ratio. The most common symptom was fever (79.9%) and 31.3% had a history of previous UTI. 72.0% of the patients had positive urine leukocyte count (>5 per field), urine gram was positive in 85.0% of samples and gram negative bacilli accounted for 77.8% for the total pathogens isolated. The most frequent uropathogens isolated were Escherichia coli and Klebsiella pneumoniae. Our E.coli isolates had a susceptibility rate higher than 90% to most of the antibiotics used, but a resistance rate of 42.6% to TMP SMX and 45.5% to ampicillin sulbactam. 6.3% of E. coli was extended-spectrum beta-lactamases producer strains. The most frequent empirical antibiotic used was amikacin, which was used in 66.0% of the patients. 17 of 90 patients who underwent voiding cistouretrography (VCUG) had vesicoureteral reflux. This study revealed that E. coli was the most frequent pathogen of community acquired UTI. We found that E. coli and other uropathogens had a high resistance rate against TMP SMX and ampicillin sulbactam. In order to ensure a successful empirical treatment, protocols should be based on local epidemiology and susceptibility rates.

    2017-06-15

    Our microbiome should be understood as one of the most complex components of the human body. The use of β-lactam antibiotics is one of the microbiome covariates that influence its composition. The extent to which our microbiota changes after an antibiotic intervention depends not only on the chemical nature of the antibiotic or cocktail of antibiotics used to treat specific infections, but also on the type of administration, duration and dose, as well as the level of resistance that each microbiota develops. We have begun to appreciate that not all bacteria within our microbiota are vulnerable or reactive to different antibiotic interventions, and that their influence on both microbial composition and metabolism may differ. Antibiotics are being used worldwide on a huge scale and the prescription of antibiotics is continuing to rise; however, their effects on our microbiota have been reported for only a limited number of them. This article presents a critical review of the antibiotics or antibiotic cocktails whose use in humans has been linked to changes in the composition of our microbial communities, with a particular focus on the gut, oral, respiratory, skin and vaginal microbiota, and on their molecular agents (genes, proteins and metabolites). We review the state of the art as of June 2016, and cover a total of circa 68 different antibiotics. The data herein are the first to compile information about the bacteria, fungi, archaea and viruses most influenced by the main antibiotic treatments prescribed nowadays.

    Inappropriate prescribing in the elderly is common, but rates across different health care systems and the impact of formulary restrictions are not well described. To determine if rates of inappropriate medication use in the elderly differ between the Veterans Affairs (VA) health care system and the private sector Medicare health maintenance organization (HMO) patients. A cross-sectional study design compared administrative pharmacy claims from 10 distinct geographic regions in the United States in the VA health care system and 10 analogous regions for patients enrolled in Medicare HMOs. The cohorts included 123,633 VA and 157,517 Medicare HMO patients aged 65 years and older. Inappropriate medication use was identified using the Zhan modification of the Beers criteria, which categorizes 33 potentially inappropriate drugs into 3 major classifications: "always avoid," "rarely appropriate," and "some indications." Comparisons between the VA health care system and the private sector Medicare HMO were performed for overall differences and stratified by gender and age. The drug formulary status of the Zhan-criteria drugs was known for the VA health system but not for the Medicare HMO patients. Compared with private sector patients, VA patients were less likely to receive any inappropriate medication (21% vs. 29%, P private sector for males (21% vs. 24%, P private sector Medicare HMOs, elderly VA patients were less likely to receive medications defined by the Zhan criteria as potentially inappropriate. A restrictive formulary that excludes 12 of the 33 Zhan criteria drugs may be a factor in the reduction of undesired prescribing patterns in elderly populations.

    Respiratory tract infections (RTIs) are the most common reason for primary care (PC) consultations and for antibiotic prescribing and use. The majority of RTIs have a viral aetiology however, and antibiotic consumption is ineffective and unnecessary. Inappropriate antibiotic use contributes greatly to antibiotic resistance (ABR) leading to complications, increased adverse events, reconsultations and costs. Improving antibiotic consumption is thus crucial to containing ABR, which has become an urgent priority worldwide. We will systematically review the evidence about interventions aimed at improving the quality of antibiotic prescribing and use for acute RTI. We will include primary peer-reviewed and grey literature of studies conducted on in-hours and out-of-hours PC patients (adults and children): (1) randomised controlled trials (RCTs), quasi-RCTs and/or cluster-RCTs evaluating the effectiveness, feasibility and acceptability of patient-targeted and clinician-targeted interventions and (2) RCTs and other study designs evaluating the effectiveness of public campaigns and regulatory interventions. We will search MEDLINE (EBSCOHost), EMBASE (Elsevier), the Cochrane Library (Wiley), CINHAL (EBSCOHost), PsychINFO (EBSCOHost), Web of Science, LILACS (Latin American and Caribbean Literature on Health Sciences), TRIP (Turning Research Into Practice) and opensgrey.eu without language restriction. We will also search the reference lists of included studies and relevant reviews. Primary outcomes include the rates of (guideline-recommended) antibiotics prescribed and/or used. Secondary outcomes include immediate or delayed use of antibiotics, and feasibility and acceptability outcomes. We will assess study eligibility and risk of bias, and will extract data. Data permitting, we will perform meta-analyses. This is a systematic review protocol and so formal ethical approval is not required. We will not collect confidential, personal or primary data.

    This paper develops a simple model where a manager of a firm in a Less-Developed Country (LDC) has the choice of whether or not to purchase an inappropriate technology in return for a bribe (kick-back) from the supplier of the technology. Provided that the manager achieves some minimum level of profit, the manager has a positive probability of not getting caught taking the bribe. The actual size of the bribe is determined by Nash axiomatic bargaining between the manager and the supplier. An i...

    Inappropriate antibiotic prescribing contributes to the generation of drug resistance worldwide, and is particularly common in China. We assessed the effectiveness of an antimicrobial stewardship programme aiming to reduce inappropriate antibiotic prescribing in paediatric outpatients by targeting providers and caregivers in primary care hospitals in rural China. We did a pragmatic, cluster-randomised controlled trial with a 6-month intervention period. Clusters were primary care township hospitals in two counties of Guangxi province in China, which were randomly allocated to the intervention group or the control group (in a 1:1 ratio in Rong county and in a 5:6 ratio in Liujiang county). Randomisation was stratified by county. Eligible participants were children aged 2-14 years who attended a township hospital as an outpatient and were given a prescription following a primary diagnosis of an upper respiratory tract infection. The intervention included clinician guidelines and training on appropriate prescribing, monthly prescribing peer-review meetings, and brief caregiver education. In hospitals allocated to the control group, usual care was provided, with antibiotics prescribed at the individual clinician's discretion. Patients were masked to their allocated treatment group but doctors were not. The primary outcome was the antibiotic prescription rate in children attending the hospitals, defined as the cluster-level proportion of prescriptions for upper respiratory tract infections in 2-14-year-old outpatients, issued during the final 3 months of the 6-month intervention period (endline), that included one or more antibiotics. The outcome was based on prescription records and analysed by modified intention-to-treat. This study is registered with the ISRCTN registry, number ISRCTN14340536. We recruited all 25 eligible township hospitals in the two counties (14 hospitals in Rong county and 11 in Liujiang county), and randomly allocated 12 to the intervention group
