Full Text Available Abstract Background Many studies associated nosocomial infections with increased hospital costs due to extra days in hospital, staff time, extra investigations and drug treatment. The cost of antibiotic treatment for these infections represents a significant part of hospital expenditure. This prospective observational study was designed to determine the daily antibiotic cost of nosocomial infections per infected adult patient in Akdeniz University Hospital. Methods All adult patients admitted to the ICUs between January 1, 2000, and June 30, 2003 who had only one nosocomial infection during their stay were included in the study. Infection sites and pathogens, antimicrobial treatment of patient and it's cost were recorded. Daily antibiotic costs were calculated per infected patient. Results Among the 8460 study patients, 817 (16.6% developed 1407 episodes of nosocomial infection. Two hundred thirty three (2.7% presented with only one nosocomial infection. Mean daily antibiotic cost was $89.64. Daily antibiotic cost was $99.02 for pneumonia, $94.32 for bloodstream infection, $94.31 for surgical site infection, $52.37 for urinary tract infection, and $162.35 for the other infections per patient. The treatment of Pseudomonas aeruginosa infections was the most expensive infection treated. Piperacillin-tazobactam and amikacin were the most prescribed antibiotics, and meropenem was the most expensive drug for treatment of the nosocomial infections in the ICU. Conclusions Daily antibiotic cost of nosocomial infections is an important part of extra costs that should be reduced providing rational antibiotic usage in hospitals.

Probiotics, including Saccharomyces boulardii, have been advocated for the prevention of Clostridium difficile infection. The aim of this project was to evaluate the effects of the removal of S. boulardii from an automatic antibiotic order set and hospital formulary on hospital onset C. difficile infection rates. A retrospective chart review was performed on all patients with hospital onset C. difficile infection during the 13 months prior (control group) and the 13 months after (study group) removal of an automatic order set linking S. boulardii capsules to certain broad spectrum antibiotics. A large 800+ bed tertiary hospital. Among all hospitalized patients, the rate of hospital onset C. difficile infection was 0.99 per 1000 patient days while the S. boulardii protocol was active compared with 1.04 per 1000 patient days (p=0.10) after S. boulardii was removed from the formulary. No difference in the rate of hospital onset C. difficile infection was detected in patients receiving the linked broad spectrum antibiotics during and after the removal of the protocol (1.25% vs. 1.51%, respectively; p=0.70). Removal of S. boulardii administration to patients receiving broad spectrum antibiotics and the hospital formulary did not impact the rate of hospital onset C. difficile infection in either the hospital population or patients receiving broad spectrum antibiotics.

Although urinary tract infection (UTI) is the most common hospital-acquired infection, there is little information about why hospitals use or do not use a range of available preventive practices. We thus conducted a multicenter study to understand better how US hospitals approach the prevention of hospital-acquired UTI. This research is part of a larger study employing both quantitative and qualitative methods. The qualitative phase consisted of 38 semistructured phone interviews with key personnel at 14 purposefully sampled US hospitals and 39 in-person interviews at 5 of those 14 hospitals, to identify recurrent and unifying themes that characterize how hospitals have addressed hospital-acquired UTI. Four recurrent themes emerged from our study data. First, although preventing hospital-acquired UTI was a low priority for most hospitals, there was substantial recognition of the value of early removal of a urinary catheter for patients. Second, those hospitals that made UTI prevention a high priority also focused on noninfectious complications and had committed advocates, or "champions," who facilitated prevention activities. Third, hospital-specific pilot studies were important in deciding whether or not to use devices such as antimicrobial-impregnated catheters. Finally, external forces, such as public reporting, influenced UTI surveillance and infection prevention activities. Clinicians and policy makers can use our findings to develop initiatives that, for example, use a champion to promote the removal of unnecessary urinary catheters or exploit external forces, such public reporting, to enhance patient safety.

Guidelines for diagnosis of infective endocarditis are largely based upon epidemiological studies in referral hospitals. Referral bias, however, might impair the validity of guidelines in non-referral hospitals. Recent studies in non-referral care centres on infective endocarditis are sparse. We conducted a retrospective epidemiological study on infective endocarditis in a large non-referral hospital in a Belgian city (Kortrijk). The medical record system was searched for all cases tagged with a putative diagnosis of infective endocarditis in the period 2003-2010. The cases that fulfilled the modified Duke criteria for probable or definite infective endocarditis were included. Compared to referral centres, an older population with infective endocarditis, and fewer predisposing cardiac factors and catheter-related infective endocarditis is seen in our population. Our patients have fewer prosthetic valve endocarditis as well as fewer staphylococcal endocarditis. Our patients undergo less surgery, although mortality rate seems to be highly comparable with referral centres, with nosocomial infective endocarditis as an independent predictor of mortality. The present study suggests that characteristics of infective endocarditis as well as associative factors might differ among non-referral hospitals and referral hospitals.

Full Text Available Background The CDC defines a nosocomial infection as a localized or systemic condition caused by an adverse reaction to the presence of an infectious agent(s or its toxin(s. It is an infection that occurs between 48 to 72 hours after admission of patients in the hospital or as soon after the hospital discharge and on the admission time, patients don't have this infection. Objectives This study aimed to characterize the prevalence of nosocomial infection in Ghaem hospital, Mashhad, Iran. Methods This retrospective study was conducted in all wards of the Ghaem hospital, Mashhad during the 1 year period (2013; the data were collected from the wards records and HIS system and analyzed by the SPSS software (version16. Results In the present study, of total 35979 hospitalized patients in different wards of the Ghaem hospital was reported 1.1% of nosocomial infection. In the meantime, overall, the most prevalent organism was Acinetobacter baumannii with a prevalence of 37.2% and the minimum was linked to the Bacillus species with a prevalence 0.3%. The highest and lowest prevalence of the nosocomial infection was in the ICU and CCU with 49.9% and 0.3%, respectively. In general, among all wards of the mentioned hospital, the most frequent nosocomial infection was pneumonia (47.4% and the lowest belonged to CSF (2.3%. Conclusions In our study, the ICU ward was accounted for the highest rate of nosocomial infection, due to the critical importance of this ward. Preventive measures and survivelance system for reduction of nosocomial infections is needed.

Full Text Available The objective of this study was to characterize and evaluate the measures of prevention and control of HI in pediatric hospitalization units. It was adopted as the method literature review. The following databases were consulted: Scielo, LILACS, PubMed and Google Scholar, as well as text books and legislation on the subject. The research was carried out from May to December 2015. Inclusion criteria were publications in the period between 1996 and 2015 that were available in the Portuguese or Spanish language. Nineteen publications were eligible, among them: 14 articles, 3 book chapters, 1 final graduation paper and 1 doctoral thesis. Data was consulted in existing legislation with regard to infection control. The results showed as key measures for proper prevention and Hospital Infection control in pediatric inpatient units: the proper use of insulation and precautions, the guidance and education of relatives and companions of hospitalized children and continuing education of staff nursing, highlighting the importance of hand washing in hospital infection control. It is important that the nursing professional has adequate knowledge of the country's legislation on the infection control in the hospital environment, so you can require that guidelines and regulations described in this are met by health care facilities, thereby helping to quality care to hospitalized children.

Human rhinovirus (HRV) is a common cause of respiratory illness in children. The impact of HRV infection on 1- to 90-day-old infants is unclear. We hypothesized that HRV infection would be clinically similar to respiratory syncytial virus (RSV) infection in the hospitalized infants. We conducted a retrospective study of hospitalized infants, who were 1-90 days old, with HRV or RSV within the Southern California Kaiser Permanente network over a 1-year period (August 2010 to October 2011). We identified 245 hospitalized infants who underwent respiratory virus testing. HRV was found in 52 infants (21%) compared to 79 infants (32%) with RSV (P = 0.008). Infants with HRV infection experienced longer hospital stays compared to those with RSV (median length of stay 4 days vs. 3 days, P = 0.009) and had fewer short hospital stays ≤3 days (P = 0.029). There was a trend in infants with HRV infection to be younger (P = 0.071) and have more fevers (P = 0.052). Recent advances in diagnostics allow for identification of a broad range of viral pathogens in infants. Compared to RSV, HRV was associated with longer hospital stays. Additional studies and improved, more specific testing, methods are needed to further define the effects of HRV infection in infants 1-90 days old. © 2014 Wiley Periodicals, Inc.

Background: Large reductions in the incidence of antibiotic-resistant strains of Staphylococcus aureus and Clostridium difficile have been observed in response to multifaceted hospital-based interventions. Reductions in antibiotic-sensitive strains have been smaller or non-existent. It has been argued that since infection control measures, such as hand hygiene, should affect resistant and sensitive strains equally, observed changes must have largely resulted from other factors, including changes in antibiotic use. We used a mathematical model to test the validity of this reasoning. Methods: We developed a mechanistic model of resistant and sensitive strains in a hospital and its catchment area. We assumed the resistant strain had a competitive advantage in the hospital and the sensitive strain an advantage in the community. We simulated a hospital hand hygiene intervention that directly affected resistant and sensitive strains equally. The annual incidence rate ratio ( IRR) associated with the intervention was calculated for hospital- and community-acquired infections of both strains. Results: For the resistant strain, there were large reductions in hospital-acquired infections (0.1 ≤ IRR ≤ 0.6) and smaller reductions in community-acquired infections (0.2 ≤ IRR ≤  0.9). These reductions increased in line with increasing importance of nosocomial transmission of the strain. For the sensitive strain, reductions in hospital acquisitions were much smaller (0.6 ≤ IRR ≤ 0.9), while communityacquisitions could increase or decrease (0.9 ≤ IRR ≤ 1.2). The greater the importance of the community environment for the transmission of the sensitive strain, the smaller the reductions. Conclusions: Counter-intuitively, infection control interventions, including hand hygiene, can have strikingly discordant effects on resistant and sensitive strains even though they target them equally, following differences in their adaptation to hospital and community

Full Text Available In developing countries, few data are available on healthcare-associated infections. In Burkina Faso, there has been a failure to take into account risk management and patient safety in the quality assurance program. The main objective of our study was to carry out an assessment of healthcare-associated infection in a first level hospital. We conducted a crosssectional study in June 2011 in the care units of Ziniaré District Hospital (Ziniaré, Burkina Faso. The hospital has been divided in three components: i hospital population (care providers, in-patients and patients’ guardians; ii healthcare and services organization; iii hospital environment. We included: care providers of the clinical services, hospital inpatients and patients’ guardians, hospitalization infrastructure and nursing units, and all the documents relating to standards and protocols. Data collection has been done by direct observation, interviews and biological samples taken at different settings. In hospital population, care providers and patients’ guardians represented a high source of infection: adherence to hygiene practice on the part of care providers was low (12/19, and no patients’ guardian experienced good conditions of staying in the hospital. In healthcare and services organization, healthcare waste management represented a high-risk source of infection. In hospital environment, hygiene level of the infrastructure in the hospital rooms was low (6.67%. Prevalence of isolated bacteria was 71.8%. Urinary-tract catheters infections were the most significant in our sample, followed by surgical-site infections. In total, 56.26% (9/19 of germs were -Lactamase producers (ESBL. They were represented by Escherichia coli and Klebsiella pneumoniae. Our analysis identified clearly healthcare-associated infection as a problem in Ziniaré district hospital. Hence, a national program of quality assurance in the hospitals should now integrate the risk infectious management

The Dutch Health Care Inspectorate investigated the preparedness of Dutch hospitals for the emergence of antibiotic resistance, and concluded that hospitals are not well prepared and are insufficiently aware that infection prevention is a prerequisite for patient safety. These conclusions are based on observations of process indicators of current practice guidelines, without including the available outcome indicators that demonstrate the persistently low incidence of infections with antibiotic resistant bacteria in Dutch hospitals. The conclusions may have negative effects on the quality of infection prevention in Dutch hospitals. Therefore, it is advisable to use outcome indicators rather than process indicators to evaluate the quality of infection prevention.

There is a paucity of data describing hospital acquired infections (HAIs) in Africa. To describe the prevalence and distribution of HAIs in acute care hospitals in Ghana. Between September and December 2016, point prevalence surveys were conducted in participating hospitals using protocols of the European Centre for Disease Prevention and Control. We reviewed medical records of eligible inpatients at or before 8am on the day of survey to identify HAIs present at the time of survey. Ten hospitals were surveyed, representing 32.9% of all acute care beds in government hospitals. Of 2107 inpatients surveyed, 184 HAIs were identified among 172 patients, corresponding to an overall prevalence of 8.2%. The prevalence values in hospitals ranged from 3.5 to 14.4% with higher proportion of infections in secondary and tertiary care facilities. The most frequent HAIs were surgical site infections (32.6%), bloodstream infections (19.5%), urinary tract infections (18.5%), and respiratory tract infections (16.3%). Device-associated infections accounted for 7.1% of HAIs. For 12.5% of HAIs, a microorganism was reported; the most isolated microorganism was Escherichia coli. Approximately 61% of all patients surveyed were on antibiotics; 89.5% of patients with an HAI received at least one antimicrobial agent on the day of survey. The strongest independent predictors for HAI were the presence of invasive device before onset of infection and duration of hospital stay. We recorded a low HAI burden compared to findings from other low and middle income countries. Copyright © 2018. Published by Elsevier Ltd.

New patterns in epidemiological characteristics of people living with HIV infection (PLWH) and the introduction of Highly Active Antiretroviral Therapy (HAART) have changed the profile of hospital admissions in this population. The aim of this study was to evaluate trends in hospital admissions, re-admissions, and mortality rates in HIV patients and to analyze the role of HCV co-infection. A retrospective cohort study conducted on all hospital admissions of HIV patients between 1993 and 2013. The study time was divided in two periods (1993-2002 and 2003-2013) to be compared by conducting a comparative cross-sectional analysis. A total of 22,901 patient-years were included in the analysis, with 6917 hospital admissions, corresponding to 1937 subjects (75% male, mean age 36±11 years, 37% HIV/HCV co-infected patients). The median length of hospital stay was 8 days (5-16), and the 30-day hospital re-admission rate was 20.1%. A significant decrease in hospital admissions related with infectious and psychiatric diseases was observed in the last period (2003-2013), but there was an increase in those related with malignancies, cardiovascular, gastrointestinal, and chronic respiratory diseases. In-hospital mortality remained high (6.8% in the first period vs. 6.3% in the second one), with a progressive increase of non-AIDS-defining illness deaths (37.9% vs. 68.3%, P<.001). The admission rate significantly dropped after 1996 (4.9% yearly), but it was less pronounced in HCV co-infected patients (1.7% yearly). Hospital admissions due to infectious and psychiatric disorders have decreased, with a significant increase in non-AIDS-defining malignancies, cardiovascular, and chronic respiratory diseases. In-hospital mortality is currently still high, but mainly because of non-AIDS-defining illnesses. HCV co-infection increased the hospital stay and re-admissions during the study period.

The purpose of our study was to conduct a needs assessment for infection prevention programs in both rural and urban hospitals in Colorado. Infection control professionals (ICPs) from Colorado hospitals participated in an online survey on training, personnel, and experience; ICP time allocation; and types of surveillance. Responses were evaluated and compared based on hospital status (rural or urban). Additionally, rural ICPs participated in an interview about resources and training. Surveys were received from 62 hospitals (77.5% response); 33 rural (75.0% response) and 29 urban (80.6% response). Fifty-two percent of rural ICPs reported multiple job responsibilities compared with 17.2% of urban ICPs. Median length of experience for rural ICPs was 4.0 years compared with 11.5 years for urban ICPs (P = .008). Fifty-one percent of rural ICPs reported no access to infectious disease physicians (0.0% urban) and 81.8% of rural hospitals reported no antimicrobial stewardship programs (31.0% urban). Through the interviews it was revealed that priorities for rural ICPs were training and communication. Our study revealed numerous differences between infection prevention programs in rural versus urban hospitals. An infection prevention outreach program established in Colorado could potentially address the challenges faced by rural hospital infection prevention departments.

Health care-associated antibiotic-resistant (AR) infections increase patient morbidity and mortality and might be impossible to successfully treat with any antibiotic. CDC assessed health care-associated infections (HAI), including Clostridium difficile infections (CDI), and the role of six AR bacteria of highest concern nationwide in several types of health care facilities. During 2014, approximately 4,000 short-term acute care hospitals, 501 long-term acute care hospitals, and 1,135 inpatient rehabilitation facilities in all 50 states reported data on specific infections to the National Healthcare Safety Network. National standardized infection ratios and their percentage reduction from a baseline year for each HAI type, by facility type, were calculated. The proportions of AR pathogens and HAIs caused by any of six resistant bacteria highlighted by CDC in 2013 as urgent or serious threats were determined. In 2014, the reductions in incidence in short-term acute care hospitals and long-term acute care hospitals were 50% and 9%, respectively, for central line-associated bloodstream infection; 0% (short-term acute care hospitals), 11% (long-term acute care hospitals), and 14% (inpatient rehabilitation facilities) for catheter-associated urinary tract infection; 17% (short-term acute care hospitals) for surgical site infection, and 8% (short-term acute care hospitals) for CDI. Combining HAIs other than CDI across all settings, 47.9% of Staphylococcus aureus isolates were methicillin resistant, 29.5% of enterococci were vancomycin-resistant, 17.8% of Enterobacteriaceae were extended-spectrum beta-lactamase phenotype, 3.6% of Enterobacteriaceae were carbapenem resistant, 15.9% of Pseudomonas aeruginosa isolates were multidrug resistant, and 52.6% of Acinetobacter species were multidrug resistant. The likelihood of HAIs caused by any of the six resistant bacteria ranged from 12% in inpatient rehabilitation facilities to 29% in long-term acute care hospitals. Although

Building new hospitals: a UK infection control perspective.

Infection control input is vital throughout the planning, design and building stages of a new hospital project, and must continue through the commissioning (and decommissioning) process, evaluation and putting the facility into full clinical service. Many hospitals continue to experience problems months or years after occupying the new premises; some of these could have been avoided by infection control involvement earlier in the project. The importance of infection control must be recognized by the chief executive of the hospital trust and project teams overseeing the development. Clinical user groups and contractors must also be made aware of infection control issues. It is vital that good working relationships are built up between the infection control team (ICT) and all these parties. ICTs need the authority to influence the process. This may require their specific recognition by the Private Finance Initiative National Unit, the Department of Health or other relevant authorities. ICTs need training in how to read design plans, how to write effective specifications, and in other areas with which they may be unfamiliar. The importance of documentation and record keeping is paramount. External or independent validation of processes should be available, particularly in commissioning processes. Building design in relation to infection control needs stricter national regulations, allowing ICTs to focus on more local usage issues. Further research is needed to provide evidence regarding the relationship between building design and the prevalence of infection.

To examine the impact of hospital-onset Clostridium difficile infection (HOCDI) on the outcomes of patients with sepsis. Most prior studies that have addressed this issue lacked adequate matching to controls, suffered from small sample size, or failed to consider time to infection. Retrospective cohort study. We identified adults with a principal or secondary diagnosis of sepsis who received care at 1 of the institutions that participated in a large multihospital database between July 1, 2004 and December 31, 2010. Among eligible patients with sepsis, we identified patients who developed HOCDI during their hospital stay. We used propensity matching and date of diagnosis to match cases to patients without Clostridium difficile infections and compared outcomes between the 2 groups. Of 218,915 sepsis patients, 2368 (1.08%) developed HOCDI. Unadjusted in-hospital mortality was significantly higher in HOCDI patients than controls (25% vs 10%, P Clostridium difficile infections was 5.1 days longer than controls (95% confidence interval: 4.4-5.8) and the median-adjusted cost increase was $4916 (P Clostridium difficile infection was associated with increased mortality, LOS, and cost. Our results can be used to assess the cost-effectiveness of prevention programs and suggest that efforts directed toward high-risk patient populations are needed. © 2014 Society of Hospital Medicine.

Full Text Available Background: Hospital Acquired Urinary Tract Infection (HAUTI is the commonest among the nosocomial infections, and hospital specific data concerning its magnitude and attributes is essential to its effective control. Materials and Methods: Prospective study was undertaken among 498 in-patients at the medical college hospital in Goa, employing the clinico-bacteriologic criteria of CDC, Atlanta, in the representative medicine and surgery wards. Antimicrobial sensitivity was tested using the Kirby-Bauer disc diffusion method. Statistical Analysis: Statistical significance of association was tested using the chi-square test and the unpaired t-test at 5% level of significance, while the strength of association was expressed as the Odd′s ratio with 95% confidence interval calculated by Wolff′s method. Results: While the overall infection rate was 8.03/100 admissions, 33.6% of the catheterized patients developed HAUTI. Effect of gender was found to remain restricted to the development of HAUTI among females at an earlier age and earlier in time series compared to males, but no overall difference in incidence in the two sexes. The factors significantly associated with HAUTI included: duration of hospitalization, per urethral catheterization and the duration of catheterization. E. coli, Pseudomonas, Kebsiella, and Candida accounted for over 90% of the isolates, and 73.5% of these were resistant to all the antibiotics for which sensitivity was tested. The remaining isolates demonstrated sensitivity to amikacin and/or cefoperazone-sulbactam. Conclusion: High infection rate coupled with widespread isolation polyantimicrobial resistant nosocomial pathogens emphasizes the importance of meticulous surveillance of nosocomial infections in the hospital, with due attention to antibiotic prescription practices.

The devastating clinical and economic implications of floods exemplify the need for effective global infection prevention and control (IPC) strategies for natural disasters. Reopening of hospitals after excessive flooding requires a balance between meeting the medical needs of the surrounding communities and restoration of a safe hospital environment. Postflood hospital preparedness plans are a key issue for infection control epidemiologists, healthcare providers, patients, and hospital administrators. We provide recent IPC experiences related to reopening of a hospital after extensive black-water floods necessitated hospital closures in Thailand and the United States. These experiences provide a foundation for the future design, execution, and analysis of black-water flood preparedness plans by IPC stakeholders.

Molecular techniques can often reveal a broader range of pathogens in respiratory infections. We aim to investigate the prevalence and age pattern of viral co-infection in children hospitalized with lower tract acute respiratory infection (LT-ARI), using molecular techniques. A nested polymerase chain reaction approach was used to detect Influenza (A, B), metapneumovirus, respiratory syncytial virus (RSV), parainfluenza (1-4), rhinovirus, adenovirus (A-F), bocavirus and coronaviruses (NL63, 229E, OC43) in respiratory samples of children with acute respiratory infection prospectively admitted to any of the GENDRES network hospitals between 2011-2013. The results were corroborated in an independent cohort collected in the UK. A total of 204 and 97 nasopharyngeal samples were collected in the GENDRES and UK cohorts, respectively. In both cohorts, RSV was the most frequent pathogen (52.9% and 36.1% of the cohorts, respectively). Co-infection with multiple viruses was found in 92 samples (45.1%) and 29 samples (29.9%), respectively; this was most frequent in the 12-24 months age group. The most frequently observed co-infection patterns were RSV-Rhinovirus (23 patients, 11.3%, GENDRES cohort) and RSV-bocavirus / bocavirus-influenza (5 patients, 5.2%, UK cohort). The presence of more than one virus in pediatric patients admitted to hospital with LT-ARI is very frequent and seems to peak at 12-24 months of age. The clinical significance of these findings is unclear but should warrant further analysis.

The standardized infection ratio (SIR) evaluates individual publicly reported health care-associated infections, but it may not assess overall performance. We piloted an infection composite score (ICS) in 82 hospitals of a single health system. The ICS is a combined score for central line-associated bloodstream infections, catheter-associated urinary tract infections, colon and abdominal hysterectomy surgical site infections, and hospital-onset methicillin-resistant Staphylococcus aureus bacteremia and Clostridium difficile infections. Individual facility ICSs were calculated by normalizing each of the 6 SIR events to the system SIR for baseline and performance periods (ICS ib and ICS ip , respectively). A hospital ICS ib reflected its baseline performance compared with system baseline, whereas a ICS ip provided information of its outcome changes compared with system baseline. Both the ICS ib (baseline 2013) and ICS ip (performance 2014) were calculated for 63 hospitals (reporting at least 4 of the 6 event types). The ICS ip improved in 36 of 63 (57.1%) hospitals in 2014 when compared with the ICS ib in 2013. The ICS ib 2013 median was 0.96 (range, 0.13-2.94) versus the 2014 ICS ip median of 0.92 (range, 0-6.55). Variation was more evident in hospitals with ≤100 beds. The system performance score (ICS sp ) in 2014 was 0.95, a 5% improvement compared with 2013. The proposed ICS may help large health systems and state hospital associations better evaluate key infectious outcomes, comparing them with historic and concurrent performance of peers.

High ventilation rate is shown to be effective for reducing cross-infection risk of airborne diseases in hospitals and isolation rooms. Natural ventilation can deliver much higher ventilation rate than mechanical ventilation in an energy-efficient manner. This paper reports a field measurement of naturally ventilated hospital wards in Hong Kong and presents a possibility of using natural ventilation for infection control in hospital wards. Our measurements showed that natural ventilation could achieve high ventilation rates especially when both the windows and the doors were open in a ward. The highest ventilation rate recorded in our study was 69.0 ACH. The airflow pattern and the airflow direction were found to be unstable in some measurements with large openings. Mechanical fans were installed in a ward window to create a negative pressure difference. Measurements showed that the negative pressure difference was negligible with large openings but the overall airflow was controlled in the expected direction. When all the openings were closed and the exhaust fans were turned on, a reasonable negative pressure was created although the air temperature was uncontrolled. The high ventilation rate provided by natural ventilation can reduce cross-infection of airborne diseases, and thus it is recommended for consideration of use in appropriate hospital wards for infection control. Our results also demonstrated a possibility of converting an existing ward using natural ventilation to a temporary isolation room through installing mechanical exhaust fans. (author)

Acinetobacter baumannii is a major hospital-acquired pathogen in Thailand that has a negative effect on patient survival. The nature of its transmission is poorly understood. To investigate the genotypic and spatiotemporal pattern of A. baumannii infection at a hospital in Thailand. The medical records of patients infected with A. baumannii at an 800-bed tertiary care hospital in southern Thailand between January 2010 and December 2011 were reviewed retrospectively. A. baumannii was identified at the genomospecies level. Carbapenemase genes were identified among carbapenem-resistant isolates associated with A. baumannii infection. A spatiotemporal analysis was performed by admission ward, time of infection and pulsed-field gel electrophoresis (PFGE) groups of A. baumannii. Nine PFGE groups were identified among the 197 A. baumannii infections. All A. baumannii isolates were assigned to International Clonal Lineage II. bla OXA-23 was the most prevalent carbapenemase gene. Outbreaks were observed mainly in respiratory and intensive care units. The association between PFGE group and hospital unit was significant. Spatiotemporal analysis identified 20 clusters of single PFGE group infections. Approximately half of the clusters involved multiple hospital units simultaneously. A. baumannii transmitted both within and between hospital wards. Better understanding and control of the transmission of A. baumannii are needed. Copyright © 2016 The Healthcare Infection Society.

OBJECTIVE To determine whether patients using the Centers for Medicare and Medicaid Services (CMS) Hospital Compare website (http://medicare.gov/hospitalcompare) can use nationally reported healthcare-associated infection (HAI) data to differentiate hospitals. DESIGN Secondary analysis of publicly available HAI data for calendar year 2013. METHODS We assessed the availability of HAI data for geographically proximate hospitals (ie, hospitals within the same referral region) and then analyzed these data to determine whether they are useful to differentiate hospitals. We assessed data for the 6 HAIs reported by hospitals to the Centers for Disease Control and Prevention (CDC). RESULTS Data were analyzed for 4,561 hospitals representing 88% of registered community and federal government hospitals in the United States. Healthcare-associated infection data are only useful for comparing hospitals if they are available for multiple hospitals within a geographic region. We found that data availability differed by HAI. Clostridium difficile infections (CDI) data were most available, with 82% of geographic regions (ie, hospital referral regions) having >50% of hospitals reporting them. In contrast, 4% of geographic regions had >50% of member hospitals reporting surgical site infections (SSI) for hysterectomies, which had the lowest availability. The ability of HAI data to differentiate hospitals differed by HAI: 72% of hospital referral regions had at least 1 pair of hospitals with statistically different risk-adjusted CDI rates (SIRs), compared to 9% for SSI (hysterectomy). CONCLUSIONS HAI data generally are reported by enough hospitals to meet minimal criteria for useful comparisons in many geographic locations, though this varies by type of HAI. CDI and catheter-associated urinary tract infection (CAUTI) are more likely to differentiate hospitals than the other publicly reported HAIs. Infect Control Hosp Epidemiol 2017;38:1167-1171.

Hospitals can better focus their efforts to prevent health care-associated infections (HAIs) if they identify specific areas for improvement. We administered a 96-question survey to infection preventionists at 71 Ascension Health hospitals to evaluate opportunities for the prevention of catheter-associated urinary tract infection, central line-associated bloodstream infection, ventilator-associated pneumonia, and surgical site infection. Seventy-one (100%) infection preventionists completed the survey. The majority of hospitals had established policies for urinary catheter placement and maintenance (55/70, 78.6%), central venous catheter maintenance (68/71, 95.8%), and care for the mechanically ventilated patient (62/66, 93.9%). However, there was variation in health care worker practice and evaluation of competencies and outcomes. When addressing device need, 55 of 71 (77.5%) hospitals used a nurse-driven evaluation of urinary catheter need, 26 of 71 (36.6%) had a team evaluation for central venous catheters on transfer out of intensive care, and 53 of 57 (93%) assessed daily ventilator support for continued need. Only 19 of 71 (26.8%) hospitals had annual nursing competencies for urinary catheter placement and maintenance, 29 of 71 (40.8%) for nursing venous catheter maintenance, and 38 of 66 (57.6%) for appropriate health care worker surgical scrubbing. We suggest evaluating infection prevention policies and practices as a first step to improvement efforts. The next steps include implementing spread of evidence-based practices, with focus on competencies and feedback on performance.

Microbiological profiles were analysed and compared for intra-abdominal, urinary, respiratory and bloodstream infections according to place of acquisition: community-acquired, with a separate analysis of healthcare-associated, and hospital-acquired. Prospective cohort study performed at a university tertiary care hospital over 1 year. Inclusion criteria were meeting the Centers for Disease Control definition of intra-abdominal, urinary, respiratory and bloodstream infections. A total of 1035 patients were included in the study. More than 25% of intra-abdominal infections were polymicrobial; multi-drug resistant gram-negatives were 38% in community-acquired, 50% in healthcare-associated and 57% in hospital-acquired. E. coli was the most prevalent among urinary infections: 69% in community-acquired, 56% in healthcare-associated and 26% in hospital-acquired; ESBL producers' pathogens were 10% in healthcare-associated and 3% in community-acquired and hospital-acquired. In respiratory infections Streptococcus pneumoniae was the most prevalent in community-acquired (54%) and MRSA in healthcare-associated (24%) and hospital-acquired (24%). A significant association was found between MRSA respiratory infection and hospitalization in the previous year (adjusted OR = 6.3), previous instrumentation (adjusted OR = 4.3) and previous antibiotic therapy (adjusted OR = 5.7); no cases were documented among patients without risk factors. Hospital mortality rate was 10% in community-acquired, 14% in healthcare-associated and 19% in hospital-acquired infection. This study shows that healthcare-associated has a different microbiologic profile than those from community or hospital acquired for the four main focus of infection. Knowledge of this fact is important because the existing guidelines for community-acquired are not entirely applicable for this group of patients.

Full Text Available Introduction: In pediatrics, the urinary tract infection is one of the most frequent bacterial infection, representing an important health problem due to its high incidence, wide etiology, asymptomatic evolution, and multiple and sever complications, relapses and sequelae.” Material and Method: We evaluated 45 children, aged between 6 months and 16 years, diagnosed and treated for urinary tract infection at the Clinical Infectious Diseases Hospital, of Constanta County, in a period of 3 years and 6 months. Results: During studied period, between January 2014 and June 2017 from a total of 9343 patients admitted to the Constanta Clinical Infectious Diseases Hospital, we selected 45 children (4.81‰ diagnosed with urinary tract infection. The average age of children with urinary tract infections was 5 years and 5 months. The gender distribution revealed a 2:1 balance in girl’s favor. The most affected group of age was 1-3 years. Fever was the dominating symptom. Urine cultures were positive for 37 cases, meanwhile for eight cases had been negative. The predominant germs are E. coli for female and for male Proteus. We noticed that for E. coli the highest sensitivity is preserved to Ertapenem -15 cases, followed by Ceftriaxone and Ciprofloxacin -10 cases each, and Gentamycin -9 cases. Conclusions: Pediatric urinary tract infection should be considered in every patient under 3 years with unexplained fever.

In Ethiopia, there is no comprehensive research that presents the whole picture of HAIs in hospitals. The objective of this study was to examine the nature and extent of HAIs in Ethiopia. Methods: A repeated cross-sectional study was conducted in two teaching hospitals. All eligible inpatients admitted for at least 48 hours on the day of the survey were included. The survey was conducted in dry and wet seasons of Ethiopia, that is, in March to April and July 2015. Physicians and nurses collected the data according to the Centers for Disease Control and Prevention definition of HAIs. Coded and cleaned data were transferred to SPSS 21 and STATA 13 for analysis. Univariate and multivariable logistic regression analyses were used to examine the prevalence of HAIs and relationship between explanatory and outcome variables. Results: A total of 908 patients were included in this survey, the median age of the patients was 27 years (interquartile range: 16–40 years. A total of 650 (71.6% patients received antimicrobials during the survey. There were 135 patients with HAI, with a mean prevalence of 14.9% (95% confidence interval 12.7–17.1. Culture results showed that Klebsiella spp. (22.44% and Staphylococcus aureus (20.4% were the most commonly isolated HAI-causing pathogens in these hospitals.

Full Text Available Infections associated with medical procedures, or hospital-acquired infections (HAIs, occur in all hospitals worldwide. An integrated infection-control program with HAI surveillance as its cornerstone can reduce the incidence of HAIs and contribute to economic benefits. The aim of this paper was to report the prevalence and epidemiological features of HAI in hospitals in Vojvodina, Serbia. The study population examined herein was compromised of all of the patients present in the ward at least 48 hours before the day of surveillance. It also included patients that were scheduled for discharge or transfer, and those temporarily absent from the ward for examinations or diagnostic procedures. Data were collected using uniform questionnaires, created by the scientific board of the study. Data from paper questionnaires were entered into a specially created electronic database and analyzed using standard statistical methods. A total of 2 435 patients were included in the study. The frequency of patients with HAI was 6.6% (95% CI: 5.6%-7.6%, and the prevalence of infection was 7.1% (95% CI: 6.1%-8.1%. HAI prevalence was significantly different depending on the ward, ranging from 1.7% in the gynecology department to 18.1% in intensive care departments. The most common type of HAI was pneumonia, representing 20.9% of all reported HAIs. The second most frequently reported type of HAI was surgical site infection (19.8%, followed by urinary tract infection (17.4%, gastro-intestinal infection (14.5% and bloodstream infection (11.0%. The most commonly found microorganisms were Enterococcus spp. (14.5%, Klebsiella pneumoniae (14.5%, Acinetobacter spp. (13.7%, coagulase-negative Staphylococcus spp. (12.1%, Pseudomonas aeruginosa (10.5% and Clostridium difficile (7.3%. The most frequently used antibiotics in therapy were third generation cephalosporins to which most of the isolates showed resistance. Although the consumption of carbapenems in this sample was only

Full Text Available Infections related to injection drug use are common. Harm reduction strategies such as syringe exchange programs and skin care clinics aim to prevent these infections in injection drug users (IDUs. Syringe exchange programs are currently prohibited by law in Florida. The goal of this study was to estimate the mortality and cost of injection drug use-related bacterial infections over a 12-month period to the county safety-net hospital in Miami, Florida. Additionally, the prevalence of HIV and hepatitis C virus among this cohort of hospitalized IDUs was estimated.IDUs discharged from Jackson Memorial Hospital were identified using the International Classification of Diseases, Ninth Revision, codes for illicit drug abuse and endocarditis, bacteremia or sepsis, osteomyelitis and skin and soft tissue infections (SSTIs. 349 IDUs were identified for chart abstraction and 92% were either uninsured or had publicly funded insurance. SSTIs, the most common infection, were reported in 64% of IDUs. HIV seroprevalence was 17%. Seventeen patients (4.9% died during their hospitalization. The total cost for treatment for injection drug use-related infections to Jackson Memorial Hospital over the 12-month period was $11.4 million.Injection drug use-related bacterial infections represent a significant morbidity for IDUs in Miami-Dade County and a substantial financial cost to the county hospital. Strategies aimed at reducing risk of infections associated with injection drug use could decrease morbidity and the cost associated with these common, yet preventable infections.

Nosocomial infections can be prevented by applying simple hygiene rules. However, they have not been sufficiently studied in the Republic of Guinea. For this purpose, we conducted a one-day study in the Conakry University Hospital surgery wards and intensive care units. Fourteen units (12 surgical wards and 2 intensive care units) participated in the study. A total of 310 patients were included. A nosocomial infection was observed in 62 patients, [20%, 95%CI 15.9-24.8%]. Surgical site infections were significantly more frequent with 42/62 cases [67.7%, 95%CI 55.3-78.1%, p = 0.0001] than other types of infections (urinary tract, skin and digestive) with 20/62 cases [32.3% 95%CI 21.9-44.6%]. The average hospital stay of 29.1 ± 23.4 days [95%CI, 23.2 ± 35.04] for patients with nosocomial infection was significantly different (p = 0.0001) from that observed in patients without nosocomial infection: 15.9 ± 16.3 days [95%CI, 13.8 ± 17.9]. Staphylococcus aureus was the pathogen most commonly isolated: 32/62 (51.6%; 95%CI 39.5-63.6%). Escherichia coli infection was identified in the bladder catheters of 13 patients [20.9%, 95%CI 12.7-32.6%]. Finally, five deaths were observed among the 62 patients with nosocomial infection. This study shows that nosocomial infections are common in Conakry University Hospital. Further studies must be conducted to identify the risk factors for nosocomial infections and to propose solutions.

Brannigan, E T; Murray, E; Holmes, A

2009-12-01

To be effective, infection prevention and control must be integrated into the complex and multiple interlinking systems within a hospital's management structure. Each of the systems must consider how activity associated with it can be optimised to minimise infection risk to patients. The components of an organisational structure to achieve these quality assurance and patient safety aims are discussed. The use of performance management tools in relation to infection control metrics is reviewed, and the use of hospital-acquired infection as a proxy indicator for deficiencies of system management is considered. Infection prevention and control cannot be the role and responsibility of a single individual or a small dedicated team; rather it should be a priority at all levels and integrated within all management systems, including the research and educational agendas.

[The Importance of Vector Management for Prevention of Hospital Infections].

Science.gov (United States)

Çetin, Hüseyin

2015-09-01

Many researches show that cockroaches, ants, some other arthropods and also rodents in hospitals, can act as potential vectors of medically important bacteria, fungi and parasites. The results of microbiological studies show that these animals play a significant role in the epidemiology of hospital infections. These vectors may be found inside of the kitchens, patient rooms, toilets, medicine stores, canteen and wards in health care environments. The importance of vector control in order to prevent the spread of nosocomial infections in healthcare facilities was discussed in this paper. This study also gives information on integrated control methods for vectors in hospitals.

Patient referral patterns and the spread of hospital-acquired infections through national health care networks.

Directory of Open Access Journals (Sweden)

Tjibbe Donker

2010-03-01

Full Text Available Rates of hospital-acquired infections, such as methicillin-resistant Staphylococcus aureus (MRSA, are increasingly used as quality indicators for hospital hygiene. Alternatively, these rates may vary between hospitals, because hospitals differ in admission and referral of potentially colonized patients. We assessed if different referral patterns between hospitals in health care networks can influence rates of hospital-acquired infections like MRSA. We used the Dutch medical registration of 2004 to measure the connectedness between hospitals. This allowed us to reconstruct the network of hospitals in the Netherlands. We used mathematical models to assess the effect of different patient referral patterns on the potential spread of hospital-acquired infections between hospitals, and between categories of hospitals (University medical centers, top clinical hospitals and general hospitals. University hospitals have a higher number of shared patients than teaching or general hospitals, and are therefore more likely to be among the first to receive colonized patients. Moreover, as the network is directional towards university hospitals, they have a higher prevalence, even when infection control measures are equally effective in all hospitals. Patient referral patterns have a profound effect on the spread of health care-associated infections like hospital-acquired MRSA. The MRSA prevalence therefore differs between hospitals with the position of each hospital within the health care network. Any comparison of MRSA rates between hospitals, as a benchmark for hospital hygiene, should therefore take the position of a hospital within the network into account.

In July 2005, New York State legislation requiring the mandatory reporting of specific hospital-associated infections (HAIs) was passed by the legislature and signed by the governor. In an effort to measure the impact of this legislation on infection control resources, the New York State Department of Health (NYSDOH) conducted a baseline survey in March 2007. This report presents an overview of the methods and results of this survey. An electronic survey of infection control resources and responsibilities was conducted by the NYSDOH on their secure data network. The survey contained questions regarding the number and percent time for infection prevention and control professional (ICP) and hospital epidemiologist (HE) staff members, ICP/HE educational background and certification, infection control program support services, activities and responsibilities of infection prevention and control program staff, and estimates of time dedicated to various activities, including surveillance. Practitioners in 222 of 224 acute care hospitals (99%) responded. The average number of ICPs per facility depended on the average daily census of acute care beds and ranged from a mean of 0.64 full-time equivalent (FTE) ICP in facilities with an average daily census of or = 900 beds. Averaging the ICP resources over the health care settings for which they were responsible revealed that the "average full-time ICP" was responsible for 151 acute care facility beds, 1.3 intensive care units (ICUs) (average, 16 ICU beds), 21 long-term care facility beds, 0.6 dialysis centers, 0.5 ambulatory surgery centers, 4.8 ambulatory/outpatient clinics, and 1.1 private practice offices. The ICPs reported that 45% of their time is dedicated to surveillance. Other activities for which ICPs reported at least partial responsibility include staff education, quality assurance, occupational health, emergency preparedness, construction, central supply/processing, and risk management. This survey was designed to

Background This report provides a national cross-sectional snapshot of infection prevention and control programs and clinician compliance with the implementation of processes to prevent healthcare associated infections (HAI) in intensive care units (ICUs). Methods All hospitals, except for Veterans Affairs hospitals, enrolled in the National Healthcare Safety Network (NHSN) were eligible to participate. Participation included: 1) completion of a survey that assessed presence of evidence-based prevention policies and clinician adherence, and 2) joining our NHSN research group. Descriptive statistics were computed. Facility characteristics and HAI rates by ICU type were compared between respondents and non-respondents. Results Of the 3,374 eligible hospitals, 975 hospitals provided data (29% response rate) on 1,653 ICUs; and, there were complete data on the presence of policies in 1,534 ICUs. The average number of infection preventionists (IPs) per 100 beds was 1.2. Certification of IP staff varied across institutions and the average hours per week of data management and secretarial support were generally low. There was variation in the presence of policies and clinician adherence to these policies. There were no differences in HAI rates between respondents and non-respondents. Conclusions Guidelines around IP staffing in acute care hospitals should be updated. In future publications we will analyze the associations between HAI rates and infection prevention and control program characteristics, presence of and clinician adherence to evidence-based policies.

The objective of this study is to evaluate the number of diabetics that seek medical treatment in emergency departments or require hospitalization for infection management in the United States. This study also assesses the socioeconomic impact of inpatient infection management among diabetics. We accessed the Healthcare Cost and Utilization Project's Nationwide Emergency Department Sample database and the Nationwide Inpatient Sample database to perform a retrospective analysis on diabetics presenting to the emergency department or hospitalized for infection management from 2006 to 2011. Emergency Department: Since 2006, nearly 10 million diabetics were annually evaluated in the emergency department. Infection was the primary reason for presentation in 10% of these visits. Among those visits, urinary tract infection was the most common infection, accounting for over 30% of emergency department encounters for infections. Other common infections included sepsis, skin and soft tissue infections, and pneumonia. Diabetics were more than twice as likely to be hospitalized for infection management than patients without diabetes. Hospitalization: Since 2006, nearly 6 million diabetics were annually hospitalized. 8-12% of these patients were hospitalized for infection management. In 2011, the inpatient care provided to patients with DM, and infection was responsible for over $48 billion dollars in aggregate hospital charges. Diabetics commonly present to the emergency department and require hospitalization for infection management. The care provided to diabetics for infection management has a large economic impact on the United States healthcare system. More efforts are needed to develop cost-effective strategies for the prevention of infection in patients with diabetes. Copyright © 2015 Elsevier Inc. All rights reserved.

This research analyzes the relationship between hospital use of automated surveillance technology (AST) for identification and control of hospital-acquired infections (HAI) and implementation of evidence-based infection control practices. Our hypothesis is that hospitals that use AST have made more progress implementing infection control practices than hospitals that rely on manual surveillance. A survey of all acute general care hospitals in California was conducted from October 2008 through January 2009. A structured computer-assisted telephone interview was conducted with the quality director of each hospital. The final sample includes 241 general acute care hospitals (response rate, 83%). Approximately one third (32.4%) of California's hospitals use AST for monitoring HAI. Adoption of AST is statistically significant and positively associated with the depth of implementation of evidence-based practices for methicillin-resistant Staphylococcus aureus and ventilator-associated pneumonia and adoption of contact precautions and surgical care infection practices. Use of AST is also statistically significantly associated with the breadth of hospital implementation of evidence-based practices across all 5 targeted HAI. Our findings suggest that hospitals using AST can achieve greater depth and breadth in implementing evidenced-based infection control practices.

Healthcare-associated infections (HCAIs) challenge public health in developing countries such as Brazil, which harbour social inequalities and variations in the complexity of healthcare and regional development. To describe the prevalence of HCAIs in hospitals in a sample of hospitals in Brazil. A prevalence survey conducted in 2011-13 enrolled 152 hospitals from the five macro-regions in Brazil. Hospitals were classified as large (≥200 beds), medium (50-199 beds) or small sized (48 h of admission to the study hospitals at the time of the survey were included. Trained epidemiologist nurses visited each hospital and collected data on HCAIs, subjects' demographics, and invasive procedures. Univariate and multivariate techniques were used for data analysis. The overall HCAI prevalence was 10.8%. Most frequent infection sites were pneumonia (3.6%) and bloodstream infections (2.8%). Surgical site infections were found in 1.5% of the whole sample, but in 9.8% of subjects who underwent surgical procedures. The overall prevalence was greater for reference (12.6%) and large hospitals (13.5%), whereas medium- and small-sized hospitals presented rates of 7.7% and 5.5%, respectively. Only minor differences were noticed among hospitals from different macro-regions. Patients in intensive care units, using invasive devices or at extremes of age were at greater risk for HCAIs. Prevalence rates were high in all geographic regions and hospital sizes. HCAIs must be a priority in the public health agenda of developing countries.

Hospital-acquired Clostridium difficile infection is associated with adverse patient outcomes and high medical costs. The incidence and severity of C. difficile has been rising in both medical and surgical patients. Our aim was to assess risk factors and variation associated with the development of nosocomial C. difficile colitis among patients undergoing colorectal resection. This was a retrospective cohort study. The study included segmental colectomy and proctectomy cases in New York State from 2005 to 2013. The study cohort included 150,878 colorectal resections. Patients with a documented previous history of C. difficile infection or residence outside of New York State were excluded. A diagnosis of C. difficile colitis either during the index hospital stay or on readmission within 30 days was the main measure. C. difficile colitis occurred in 3323 patients (2.2%). Unadjusted C. difficile colitis rates ranged from 0% to 11.3% among surgeons and 0% to 6.8% among hospitals. After controlling for patient, surgeon, and hospital characteristics using mixed-effects multivariable analysis, significant unexplained variation in C. difficile rates remained present across hospitals but not surgeons. Patient factors explained only 24% of the total hospital-level variation, and known surgeon and hospital-level characteristics explained an additional 8% of the total hospital-level variation. Therefore, ≈70% of the hospital variation in C. difficile infection rates remained unexplained by captured patient, surgeon, and hospital factors. Furthermore, there was an ≈5-fold difference in adjusted C. difficile rates across hospitals. A limited set of hospital and surgeon characteristics was available. Colorectal surgery patients appear to be at high risk for C. difficile infection, and alarming variation in nosocomial C. difficile infection rates currently exists among hospitals after colorectal resection. Given the high morbidity and cost associated with C. difficile colitis

Opportunistic infections are common in HIV-infected patients especially those who progress to acquired immunodeficiency syndrome. There are many factors involved in the prevalence of opportunistic infections. We investigated the patterns of opportunistic infection in HIV-infected patients admitted to Airlangga University Hospital Surabaya. This study was an observational study, conducted in adults patients with HIV infection from January 2016 to September 2017. Data collected from the medical records of the patients. The number of samples in this study was 58. The mean age was 42.9 years, mostly male. Most patients admitted were in clinical stadium III or IV. Heterosexual transmission is a common risk factor in patients. The most prevalent opportunistic infections found in patients were oral candidiasis (58.6%), followed by pulmonary tuberculosis (41.4%) and pneumonia/PCP (41.4%). Other infections found were toxoplasmosis, chronic diarrhea, cytomegalovirus, meningitis TB, hepatitis C, amoebiasis, and cerebritis. Opportunistic infections occurred more often in age≥40 years and increased as clinical stadium get worse. From the results, we conclude that oral candidiasis and pulmonary tuberculosis were the most common opportunistic infections found in Airlangga University Hospital. The pattern of opportunistic infections in this study could help the hospital to set priorities related to the management of patients.

Tuberculosis (TB) infection control measures are very important to prevent nosocomial transmission and protect healthcare workers (HCWs) in hospitals. The TB infection control situation in TB treatment institutions in southeastern China has not been studied previously. Therefore, the aim of this study was to investigate the implementation of TB infection control measures in TB-designated hospitals in Zhejiang Province, China. Cross-sectional survey using observation and interviews. All TB-designated hospitals (n=88) in Zhejiang Province, China in 2014. Managerial, administrative, environmental and personal infection control measures were assessed using descriptive analyses and univariate logistic regression analysis. The TB-designated hospitals treated a median of 3030 outpatients (IQR 764-7094) and 279 patients with confirmed TB (IQR 154-459) annually, and 160 patients with TB (IQR 79-426) were hospitalised in the TB wards. Most infection control measures were performed by the TB-designated hospitals. Measures including regular monitoring of TB infection control in high-risk areas (49%), shortening the wait times (42%), and providing a separate waiting area for patients with suspected TB (46%) were sometimes neglected. N95 respirators were available in 85 (97%) hospitals, although only 44 (50%) hospitals checked that they fit. Hospitals with more TB staff and higher admission rates of patients with TB were more likely to set a dedicated sputum collection area and to conduct annual respirator fit testing. TB infection control measures were generally implemented by the TB-designated hospitals. Measures including separation of suspected patients, regular monitoring of infection control practices, and regular fit testing of respirators should be strengthened. Infection measures for sputum collection and respirator fit testing should be improved in hospitals with lower admission rates of patients with TB. Published by the BMJ Publishing Group Limited.

Surgical site infection rates are of great interest to patients, surgeons, hospitals and third-party payers. While previous studies have reported hospital-acquired infection rates that are nonspecific to all surgical services, there remain no overall reported infection rates focusing specifically on plastic surgery in the literature. To estimate the reported surgical site infection rate in plastic surgery procedures over a 10-year period at an academic hospital in Canada. A review was conducted on reported plastic surgery surgical site infection rates from 2003 to 2013, based on procedures performed in the main operating room. For comparison, prospective infection surveillance data over an eight-year period (2005 to 2013) for nonplastic surgery procedures were reviewed to estimate the overall operative surgical site infection rates. A total of 12,183 plastic surgery operations were performed from 2003 to 2013, with 96 surgical site infections reported, corresponding to a net operative infection rate of 0.79%. There was a 0.49% surgeon-reported infection rate for implant-based procedures. For non-plastic surgery procedures, surgical site infection rates ranged from 0.04% for cataract surgery to 13.36% for high-risk abdominal hysterectomies. The plastic surgery infection rate at the study institution was found to be site infection rates. However, these results do not report patterns of infection rates germane to procedures, season, age groups or sex. To provide more in-depth knowledge of this topic, multicentre studies should be conducted.

The major challenge for a burn team is nosocomial infection in burn patients, which is known to cause over 50% of burn deaths. Most studies on infection in burn patients focus on burn wound infection, whereas other nosocomial infections in these patients are not well described. We undertook this study to determine three types of nosocomial infections viz., burn wound infection, urinary tract infection, and blood stream infection in burn patients in a burn hospital in Iran. During the one year period (May 2003 to April 2004), 182 patients were included in this study. Blood, urine and wound biopsy samples were taken 7 and 14 days after admission to Taleghani Burn hospital. Isolation and identification of microorganisms was done using the standard procedure. Disk diffusion test were performed for all the isolates for antimicrobial susceptibility. Of the 182 patients, 140 (76.9%) acquired at least one type of infection of the 140, 116 patients (82.8%) were culture positive on day 7 while 24 (17.2%) on 14 days after admission. Primary wound infection was most common (72.5%), followed by blood stream (18.6%) and urinary tract infections (8.9 %). The microorganisms causing infections were Pseudomonas aeruginosa (37.5%), Staphylococcus aureus (20.2%), and Acinetobacter baumanni (10.4%). Among these isolates P. aeruginosa was found to be 100 per cent resistant to amikacin, gentamicin , carbenicillin, ciprofloxacin, tobramycin and ceftazidime; 58 per cent of S. aureus and 60 per cent of coagulase negative Staphylococcus were methicillin resistant. High prevalence of nosocomial infections and the presence of multidrug resistant bacteria, and methicillin resistant S. aureus in patients at Taleghani Burn Hospital suggest continuous surveillance of burn infections and develop strategies for antimicrobial resistance control and treatment of infectious complications.

To analyze the quality of infection control activities, bacteriological data relevant to infection control was evaluated through the microbiological data warehouse networking hospitals in two medical regions. Data regarding bacterial test results of 19 hospitals were extracted from two microbiological laboratory information data bases. The rate of MRSA among total S. aureus was used as a general indicator of infection control activities. The occupancy rate of nasal or pharyngeal swabs among MRSA-positive bacteriological samples was used as an indicator of attention paid for infection control in intensive care wards. The number of blood culture sets per examined patient was utilized as an indicator for life-long vocational education on updated medical practice relevant to infectious diseases. The rate of MRSA was significantly higher in secondary private hospitals. The occupancy rate of nasal or pharyngeal swabs was significantly higher in tertiary hospitals. The average number of blood culture set per examined patient were 1.55, 1.54 and 1.39 in tertiary, secondary public and secondary private hospitals, respectively; however, there were no statistical differences between groups. Data bases of microbiological test results shared by hospital laboratories are useful for evaluating regional infection control activities.

Full Text Available Background: An estimated 4% of hospital admissions acquired healthcare-associated infections (HAIs and accounted for $9.8 (USD billion in direct cost during 2011. In 2010, nearly 140 000 of the 3.5 million potentially preventable hospitalizations (PPHs may have acquired an HAI. There is a knowledge gap regarding the co-occurrence of these events. Aims: To estimate the period occurrences and likelihood of acquiring an HAI for the PPH population. Methods: Retrospective, cross-sectional study using logistic regression analysis of 2011 Texas Inpatient Discharge Public Use Data File including 2.6 million admissions from 576 acute care hospitals. Agency for Healthcare Research and Quality Prevention Quality Indicator software identified PPH, and existing administrative data identification methodologies were refined for Clostridium difficile infection, central line–associated bloodstream infection, catheter-associated urinary tract infection, and ventilator-associated pneumonia. Odds of acquiring HAIs when admitted with PPH were adjusted for demographic, health status, hospital, and community characteristics. Findings: We identified 272 923 PPH, 14 219 HAI, and 986 admissions with PPH and HAI. Odds of acquiring an HAI for diabetic patients admitted for lower extremity amputation demonstrated significantly increased odds ratio of 2.9 (95% confidence interval: 2.16-3.91 for Clostridium difficile infection. Other PPH patients had lower odds of acquiring HAI compared to non-PPH patients, and results were frequently significant. Conclusions: Clinical implications include increased risk of HAI among diabetic patients admitted for lower extremity amputation. Methodological implications include identification of rare events for inpatient subpopulations and the need for improved codification of HAIs to improve cost and policy analyses regarding allocation of resources toward clinical improvements.

The third most common healthcare-associated infection is surgical site infection (SSI), accounting for 14%-16% of infections. These SSIs are associated with high morbidity, numerous deaths, and greater cost. A prospective study was conducted to assess the incidence of SSI in a single university hospital in Croatia. We used the Hospital in Europe Link for Infection Control through Surveillance (HELICS) protocol for surveillance. The SSIs were classified using the standard definition of the National Nosocomial Infections Surveillance (NNIS) system. The overall incidence of SSI was 1.44%. The incidence of infection in the open cholecystectomy group was 6.06%, whereas in the laparoscopic group, it was only 0.60%. The incidence density of in-hospital SSIs per 1,000 post-operative days was 5.76. Patients who underwent a laparoscopic cholecystectomy were significantly younger (53.65±14.65 vs. 64.42±14.17 years; pconcept for the monitoring of SSI, but in the case of cholecystectomy, additional factors such as antibiotic appropriateness, gallbladder entry, empyema of the gallbladder, and obstructive jaundice must be considered.

Environmental risk factors for Clostridium difficile infections (CDIs) have been described at the room or unit level but not the hospital level. To understand the environmental risk factors for CDI, we investigated the association between institutional- and individual-level CDI. We performed a retrospective cohort study using the Healthcare Cost and Utilization Project state inpatient databases for California (2005-2011). For each patient's hospital stay, we calculated the hospital CDI incidence rate corresponding to the patient's quarter of discharge, while excluding each patient's own CDI status. Adjusting for patient and hospital characteristics, we ran a pooled logistic regression to determine individual CDI risk attributable to the hospital's CDI rate. There were 10,329,988 patients (26,086 cases and 10,303,902 noncases) who were analyzed. We found that a percentage point increase in the CDI incidence rate a patient encountered increased the odds of CDI by a factor of 1.182. As a point of comparison, a 1-percentage point increase in the CDI incidence rate that the patient encountered had roughly the same impact on their odds of acquiring CDI as a 55.8-day increase in their length of stay or a 60-year increase in age. Patients treated in hospitals with a higher CDI rate are more likely to acquire CDI. Copyright © 2016 Association for Professionals in Infection Control and Epidemiology, Inc.

Previous attempts at costing infection control programmes have tended to focus on accounting costs rather than economic costs. For studies using economic costs, estimates tend to be quite crude and probably underestimate the true cost. One of the largest costs of any intervention is staff time, but this cost is difficult to quantify and has been largely ignored in previous attempts. To design and evaluate the costs of hospital-based infection control interventions or programmes. This article also discusses several issues to consider when costing interventions, and suggests strategies for overcoming these issues. Previous literature and techniques in both health economics and psychology are reviewed and synthesized. This article provides a set of generic, transferable costing guidelines. Key principles such as definition of study scope and focus on large costs, as well as pitfalls (e.g. overconfidence and uncertainty), are discussed. These new guidelines can be used by hospital staff and other researchers to cost their infection control programmes and interventions more accurately.

With the development and widespread use of combination antiretroviral therapy, HIV-infected women live longer, healthier lives. Previous research has shown that, since the adoption of combination antiretroviral therapy in the United States, rates of morbidity and adverse obstetric outcomes remained higher for HIV-infected pregnant women compared with HIV-uninfected pregnant women. Monitoring trends in the outcomes these women experience is essential, as recommendations for this special population continue to evolve with the progress of HIV treatment and prevention options. We conducted an analysis comparing rates of hospitalizations and associated outcomes among HIV-infected and HIV-uninfected pregnant women in the United States from 2004 through 2011. We used cross-sectional hospital discharge data for girls and women age 15-49 from the 2004, 2007, and 2011 Nationwide Inpatient Sample, a nationally representative sample of US hospital discharges. Demographic characteristics, morbidity outcomes, and time trends were compared using χ(2) tests and multivariate logistic regression. Analyses were weighted to produce national estimates. In 2011, there were 4751 estimated pregnancy hospitalizations and 3855 delivery hospitalizations for HIV-infected pregnant women; neither increased since 2004. Compared with those of HIV-uninfected women, pregnancy hospitalizations of HIV-infected women were more likely to be longer, be in the South and Northeast, be covered by public insurance, and incur higher charges (all P pregnant women with HIV infection had higher rates for many adverse outcomes. Compared to 2004, hospitalizations of HIV-infected pregnant women in 2011 had higher odds of gestational diabetes (adjusted odds ratio, 1.81; 95% confidence interval, 1.16-2.84), preeclampsia/hypertensive disorders of pregnancy (adjusted odds ratio, 1.58; 95% confidence interval, 1.12-2.24), viral/mycotic/parasitic infections (adjusted odds ratio, 1.90; 95% confidence interval, 1

Critically ill patients are at marked risk of hospital-acquired infections, which increase patients' morbidity and mortality. Registered nurses are the main health care providers of physical care, including hygiene to reduce and prevent hospital-acquired infections, for hospitalized critically ill patients. To investigate a new patient hand hygiene protocol designed to reduce hospital-acquired infection rates and improve nurses' hand-washing compliance in an intensive care unit. A preexperimental study design was used to compare 12-month rates of 2 common hospital-acquired infections, central catheter-associated bloodstream infection and catheter-associated urinary tract infection, and nurses' hand-washing compliance measured before and during use of the protocol. Reductions in 12-month infection rates were reported for both types of infections, but neither reduction was statistically significant. Mean 12-month nurse hand-washing compliance also improved, but not significantly. A hand hygiene protocol for patients in the intensive care unit was associated with reductions in hospital-acquired infections and improvements in nurses' hand-washing compliance. Prevention of such infections requires continuous quality improvement efforts to monitor lasting effectiveness as well as investigation of strategies to eliminate these infections. ©2015 American Association of Critical-Care Nurses.

To compare the severity of single respiratory syncytial virus (RSV) infections with that of coinfections. A historical cohort was studied, including hospitalized infants with acute RSV infection. Nasopharyngeal aspirate samples were collected from all patients to detect eight respiratory viruses using molecular biology techniques. The following outcomes were analyzed: duration of hospitalization and of oxygen therapy, intensive care unit admission and need of mechanical ventilation. Results were adjusted for confounding factors (prematurity, age and breastfeeding). A hundred and seventy six infants with bronchiolitis and/or pneumonia were included in the study. Their median age was 4.5 months. A hundred and twenty one had single RSV infection and 55 had coinfections (24 RSV + adenovirus, 16 RSV + human metapneumovirus and 15 other less frequent viral associations). The four severity outcomes under study were similar in the group with single RSV infection and in the coinfection groups, independently of what virus was associated with RSV. Virus coinfections do not seem to affect the prognosis of hospitalized infants with acute RSV infection.

Full Text Available Many studies have evaluated methicillin-resistant Staphylococcus aureus (MRSA infections during single hospitalizations and subsequent readmissions to the same institution. None have assessed the comprehensive burden of MRSA infection in the period after hospital discharge while accounting for healthcare utilization across institutions.We conducted a retrospective cohort study of adult patients insured by Harvard Pilgrim Health Care who were newly-detected to harbor MRSA between January 1991 and December 2003 at a tertiary care medical center. We evaluated all MRSA-attributable infections associated with hospitalization in the year following new detection, regardless of hospital location. Data were collected on comorbidities, healthcare utilization, mortality and MRSA outcomes. Of 591 newly-detected MRSA carriers, 23% were colonized and 77% were infected upon detection. In the year following detection, 196 (33% patients developed 317 discrete and unrelated MRSA infections. The most common infections were pneumonia (34%, soft tissue (27%, and primary bloodstream (18% infections. Infections occurred a median of 56 days post-detection. Of all infections, 26% involved bacteremia, and 17% caused MRSA-attributable death. During the admission where MRSA was newly-detected, 14% (82/576 developed subsequent infection. Of those surviving to discharge, 24% (114/482 developed post-discharge infections in the year following detection. Half (99/185, 54% of post-discharge infections caused readmission, and most (104/185, 55% occurred over 90 days post-discharge.In high-risk tertiary care patients, newly-detected MRSA carriage confers large risks of infection and substantial attributable mortality in the year following acquisition. Most infections occur post-discharge, and 18% of infections associated with readmission occurred in hospitals other than the one where MRSA was newly-detected. Despite gains in reducing MRSA infections during hospitalization, the

There are limited data on respiratory syncytial virus (RSV) infection among children in settings with a high prevalence of human immunodeficiency virus (HIV). We studied the epidemiology of RSV-associated acute lower respiratory tract infection (ALRTI) hospitalizations among HIV-infected and HIV-uninfected children in South Africa. Children aged infection among HIV-infected and uninfected children were examined. The relative risk of hospitalization in HIV-infected and HIV-uninfected children was calculated in 1 site with population denominators. Of 4489 participants, 4293 (96%) were tested for RSV, of whom 1157 (27%) tested positive. With adjustment for age, HIV-infected children had a 3-5-fold increased risk of hospitalization with RSV-associated ALRTI (2010 relative risk, 5.6; [95% confidence interval (CI), 4.5-6.4]; 2011 relative risk, 3.1 [95% CI, 2.6-3.6]). On multivariable analysis, HIV-infected children with RSV-associated ALRTI had higher odds of death (adjusted odds ratio. 31.1; 95% CI, 5.4-179.8) and hospitalization for >5 days (adjusted odds ratio, 4.0; 95% CI, 1.5-10.6) than HIV-uninfected children. HIV-infected children have a higher risk of hospitalization with RSV-associated ALRTI and a poorer outcome than HIV-uninfected children. These children should be targeted for interventions aimed at preventing severe RSV disease.

Full Text Available Health care associated infections (HCAIs add incrementally to the morbidity, mortality, and cost expected of the patient’s underlying diseases alone. Approximately, about half all cases of HCAIs are associated with medical devices. As Candida medical device-associated infection is highly drug resistant and can lead to serious life-threatening complications, there is a need of continuous surveillance of these infections to initiate preventive and corrective measures. The present study was conducted at a rural tertiary care hospital of India with an aim to evaluate the rate of medical device-associated Candida infections. Three commonly encountered medical device-associated infections (MDAI, catheter-associated urinary tract infection (CA-UTI, intravascular catheter-related blood stream infections (CR-BSI, and ventilator-associated pneumonia (VAP, were targeted. The overall rate of MDAI in our hospital was 2.1 per 1000 device days. The rate of Candida related CA-UTI and CR-BSI was noted as 1.0 and 0.3, respectively. Untiring efforts taken by team members of Hospital Acquired Infection Control Committee along with maintenance of meticulous hygiene of the hospital and wards may explain the low MDAI rates in our institute. The present surveillance helped us for systematic generation of institutional data regarding MDAI with special reference to role of Candida spp.

Clostridium difficile infection (CDI) is a considerable health issue in the United States and represents the most common healthcare-associated infection. Solid organ transplant recipients are at increased risk of CDI, which can affect both graft and patient survival. However, little is known about the impact of CDI on health services utilization posttransplantation. We examined hospital-onset CDI from 2012 to 2014 among transplant recipients in the University HealthSystem Consortium, which includes academic medical center-affiliated hospitals in the United States. Infection was five times more common among transplant recipients than among general medicine inpatients (209 vs 40 per 10 000 discharges), and factors associated with CDI among transplant recipients included transplant type, risk of mortality, comorbidities, and inpatient complications. Institutional risk-standardized CDI varied more than 3-fold across high-volume hospitals (infection ratio 0.54-1.82, median 1.04, interquartile range 0.78-1.28). CDI was associated with increased 30-day readmission, transplant organ complications, cytomegalovirus infection, inpatient costs, and lengths of stay. Total observed inpatient days and direct costs for those with CDI were substantially higher than risk-standardized expected values (40 094 vs 22 843 days, costs $198 728 368 vs $154 020 528). Further efforts to detect, prevent, and manage CDI among solid organ transplant recipients are warranted. © Copyright 2015 The American Society of Transplantation and the American Society of Transplant Surgeons.

Togneri, Ana M; Podestá, Laura B; Pérez, Marcela P; Santiso, Gabriela M

A twelve-year retrospective review of Staphylococcus aureus infections in adult and pediatric patients (AP and PP respectively) assisted in the Hospital Interzonal General de Agudos Evita in Lanús was performed to determine the incidence, foci of infection, the source of infection and to analyze the profile of antimicrobial resistance. An amount of 2125 cases of infection in AP and 361 in PP were documented. The incidence in AP decreased significantly in the last three years (χ i 2 ; p<0.05); in PP it increased significantly during the last five years (χ 2 ; p<0.0001). In both populations was detected a notable increase in skin infections and associated structures (PEA) in bacteremia to the starting point of a focus on PEA, and in total S. aureus infections of hospital-onset (χ 2 ; p < 0.005). Methicillin-resistance (MRSA) increased from 28 to 78% in PP; in AP it remained around 50%, with significant reduction in accompanying antimicrobial resistance to non-β-lactams in both groups of MRSA. In S. aureus documented from community onset infections (CO-MRSA) in the last three years, the percentage of methicillin-resistance was 57% in PP and 37% in AP; in hospital-onset infections it was 43% and 63% respectively. Although data showed that S. aureus remains a pathogen associated with the hospital-onset, there was an increase of CO-MRSA infections with predominance in PEA in both populations.

Applying Prevention and Control of Infection (PCI) standards in hospitals reduces probable risks to patients, staff and visitors; it also increases efficiency, and ultimately improves productivity of hospitals. The current study aimed to determine the status quo of international standards of PCI in hospitals located in the north of Iran. This cross-sectional study was conducted in 23 hospitals. Data collection tool was a questionnaire with confirmed validity and reliability. . In this regard, 260 managers, section supervisors and infection control nurses participated in the study according to census basis. SPSS software version 16 was employed to analyze the data through descriptive and analytical statistics. Among the studied hospitals, 18 hospitals were public. Hospitals enjoyed 77.2% of leadership and programming, 80.8% of focus of programs, 67.4% of isolating methods, 88.2% of hand health and protection techniques, 78.8% of improving patient's safety and quality, 90.3% of training personnel, and 78.7% of the average status quo of PCI standards. This study revealed that PCI standards were significantly observed in the studied hospitals and that there were necessary conditions for full deployment of nosocomial infection surveillance.

The incidence and associated morbidity of Clostridium difficile (CD) infection has been increasing at an alarming rate in North America. Clostridium difficile-associated diarrhea (CDAD) is the leading cause of nosocomial diarrhea in the USA. Patients with CDAD have longer average hospital admissions and additional hospital costs. Evidence has demonstrated that patients with inflammatory bowel disease (IBD) have a higher incidence of CD in comparison to the general population. The aim of this study was to compare the rate of recurrence of CD in hospitalized pediatric patients with IBD compared to hospitalized controls. The secondary aim was to evaluate whether infection with CD resulted in a more severe disease course of IBD. This was a nested case control retrospective study of hospitalized pediatric patients. Diagnosis of CD was confirmed with stool Toxin A and B analysis. The following data were obtained from the medical records: demographic information, classification of IBD including location of disease, IBD therapy, and prior surgeries. In addition, prior hospital admissions within 1 year and antibiotic exposure were recorded. The same information was recorded following CD infection. Cases were patients with IBD and CD; two control populations were also studied: patients with CD but without IBD, and patients with IBD but without CD. For aim 1, a total of 111 eligible patients with IBD and CD infection and 77 eligible control patients with CD infection were included. The rate of recurrence of CD in the IBD population was 34% compared to 7.5% in the control population (P < 0.0001). In evaluating the effect of CD infection on IBD disease severity, we compared the 111 IBD patients with CD to a second control population of 127 IBD patients without CD. 57% of IBD-CD patients were readmitted with an exacerbation of disease within 6 months of infection with CD and 67% required escalation of therapy following CD infection, compared to 30% of IBD patients without CD (P

[Hospital hygiene - outbreak management of nosocomial infections].

Science.gov (United States)

Kerwat, Klaus; Wulf, Hinnerk

2012-04-01

According to §6, section 3 of the German Protection against Infections Act [Infektionsschutzgesetz (IfSG)] an outbreak is defined as the occurrence in large numbers of nosocomial infections for which an epidemiological relationship is probable or can be assumed. About 2-10% of nosocomial infections in hospitals (about 5% in intensive care wards) occur within the framework of an outbreak. The heaped occurrence of nosocomial infections can be declared according to the prescribed surveillance of nosocomial infections (§23 IfSG) when, in the course of this assessment, a statistically significant increase in the rate of infections becomes apparent. On the other hand, the occurrence of an outbreak can also be recognized through the vigilance of all involved personnel and a general sensibilization towards this subject. The names of patients involved in outbreaks need not be reported to the responsible health authorities. As a consequence of the report the health authorities become involved in the investigation to determine the cause and its elimination, and to provide support and advice. The outbreak management should be oriented on the respective recommendations of the Robert Koch Institute. © Georg Thieme Verlag Stuttgart · New York.

Gabriel, L; Beriot-Mathiot, A

2014-09-01

In most healthcare systems, third-party payers fund the costs for patients admitted to hospital for Clostridium difficile infection (CDI) whereas, for CDI cases arising as complications of hospitalization, not all related costs are refundable to the hospital. We therefore aimed to critically review and categorize hospital costs and length of hospital stay (LOS) attributable to Clostridium difficile infection and to investigate the economic burden associated with it. A comprehensive literature review selected papers describing the costs and LOS for hospitalized patients as outcomes of CDI, following the use of statistics to identify costs and LOS solely attributable to CDI. Twenty-four studies were selected. Estimated attributable costs, all ranges expressed in US dollars, were $6,774-$10,212 for CDI requiring admission, $2,992-$29,000 for hospital-acquired CDI, and $2,454-$12,850 where no categorization was made. The ranges for LOS values were 5-13.6, 2.7-21.3, and 2.8-17.9 days, respectively. The categorization of CDI attributable costs allows budget holders to anticipate the cost per CDI case, a perspective that should enrich the design of appropriate incentives for the various budget holders to invest in prevention so that CDI prevention is optimized globally.

Full Text Available Hospital infections currently represent the interests of the international order, as it involves the performance of health professionals, the quality of physical facilities and materials of daily use. This study aimed to verify the recognition of the importance of hand hygiene in preventing nosocomial infection by health professionals. This is a cross-sectional study, which was applied in semi-structured form, a sample of 60 professionals, including nurses, technicians and / or licensed practical nurses and doctors, working in a public hospital located in Bahia, in October 2011, complying with ethical requirements for studies in humans. The results showed that 98.3% of respondents recognize the importance of hand hygiene in preventing hospital infection, 83.3% said they master the technique, however only 53.4% described it correctly. We conclude that despite the awareness of professionals about the importance and availability of products for hand hygiene, it is necessary to implement educational activities that motivate and intensify the adhesion of professionals

Nosocomial infections due to Gram-negative bacteria are very important since they are associated with high morbidity and high hospital costs. A prospective study of 250 inpatients was carried out, 200 of whom had Gram-negative bacterial infections. Patients were divided into groups of 50 according to the localization of the infection (urinary, surgical wound, respiratory tract and bacteremia), with a control group of 50 patients with similar characteristics but no infection. We calculated the cost for the different groups by multiplying the average length of hospital stay in days by the daily cost of the stay. Significant differences were observed in the average length of stay per patient according to the type of infection and how it was acquired. In terms of cost, nosocomial infection due to Gram-negative bacteria was 1,049,139 pesetas more expensive than community-acquired infection. The cost of the stay for patients with postsurgical infection due to Gram-negative bacteria was 1,108, 252 pesetas more expensive than for the group of control patients. Nosocomial infection due to Gram-negative bacteria is associated with a prolongation in hospital stay of 9 to 28 days, which is the factor that most reflects the cost that can be attributed to nosocomial infection. Consensual and protocolized measures which allow for better clinical management need to be developed.

Health care-associated infection (HAI) is costly to hospitals and potentially life-threatening to patients. Numerous infection prevention programs have been implemented in hospitals across the United States. Yet, little is known about infection prevention practices and implementation in rural hospitals. The purpose of this study was to understand the infection prevention practices used by rural Veterans' Affairs (VA) hospitals and the unique factors they face in implementing these practices. This study used a sequential, mixed methods approach. Survey data to identify the HAI prevention practices used by rural VA hospitals were collected, analyzed, and used to inform the development of a semistructured interview guide. Phone interviews were conducted followed by site visits to rural VA hospitals. We found that most rural VA hospitals were using key recommended infection prevention practices. Nonetheless, a number of challenges with practice implementation were identified. The 3 most prominent themes were: (1) lack of human capital including staff with HAI expertise; (2) having to cultivate needed resources; and (3) operating as a system within a system. Rural VA hospitals are providing key infection prevention services to ensure a safe environment for the veterans they serve. However, certain factors, such as staff expertise, limited resources, and local context impacted how and when these practices were used. The creative use of more accessible alternative resources as well as greater flexibility in implementing HAI-related initiatives may be important strategies to further improve delivery of these important services by rural VA hospitals.

Full Text Available Nosocomial infection is an increasing problem. The global problem of antimicrobial resistance is particularly pressing in developing countries, where the infectious disease burden is high and cost constraints prevent the widespread application of newer, more expensive agents. In a prospective study, 203 consecutive cases with hospital-acquired infection in a university hospital in Bushehr port were evaluated. The most common hospital-acquired infection was urinary (76 cases, conjunctivitis (16 cases, bacteremia (8 cases, meningitis (5 cases, wound (3 cases, empyema (2 cases and peritonitis (1 case. The patients with hospital-acquired infection were from surgical and internal medicine I.C.Us (53.2% & 15.6%, respectively.

The most resistant organisms to antimicrobial agents were Acinetobacter baumannii and Pseudomonas aeruginosa 97 & 93.3% of these bacteria were resistant to third generation cephalosporins. The isolated Staphylococcal species were resistant to amikacin (94%. In conclusion, gram negative bacteria were the most common etiologic agent of hospital-acquired infection and had a high level of resistance to amikacin and third generation cephalosporins. Therefore, new therapeutic strategies should be designed to combat these microorganisms.

The purpose of this study was to analyze the effect of hospital volume and charges on the rate of surgical site infections for total hip replacements (THRs) in New York State (NYS). In NYS, higher volume hospitals have higher charges after THR. The study team analyzed 93,620 hip replacements performed in NYS between 2008 and 2011. Hospital charges increased significantly from $43,713 in 2008 to $50,652 in 2011 (P<.01). Compared with lower volume hospitals, patients who underwent THR at the highest volume hospitals had significantly lower surgical site infection rates (P=.003) and higher total hospital charges (P<.0001). The study team found that in the highest volume hospitals, preventing one surgical site infection was associated with $1.6 million dollars in increased charges. © 2014 by the American College of Medical Quality.

Many patients suffering from viral infections attend to health care centers. Data gathered from viral infections is limited to specific cases such as AIDS, viral hepatitis and Influenza. There is a significant lack of reliable documentation about other viral infections. In this study the prevalence and related costs of viral infections in hospitals of Shiraz University of Medical Sciences were reviewed. In this cross-sectional study the data were extracted from files of 1319 patients with viral infection admitted in two university hospitals during a five year period (1999-2004). The frequencies of different viral infections along with their demographic data were analyzed. The mean age of the patients was 29.24 with the range of 90 years. Hospitalization days were 8636 in 40 different wards in two hospitals. US$ 30.84 was the daily mean cost for each admitted patient. Viral meningitis was most frequent (14.2%) and 8.4% of patients died during hospitalization. This study confirms the necessity of expanding management programs for viral infections especially hepatitis B in youths in Iran. Unspecified viral infections cost much more than specified viral diseases. Viral infection costs can be reduced by finding more sensitive and specific diagnostic methods. (author)

Although most patients respond well to discontinuation of antibiotics, 20%–30% of patients relapse. To initiate early therapeutic measures, the risk factors for recurrent CDI must be identified, although very few Japanese studies have used standard surveillance definitions to identify these risk factors.Methods: We retrospectively reviewed the medical records of patients with health care facility-onset CDI between August 2011 and September 2013. Patients with diarrhea who were positive for Clostridium difficile (via an enzyme immunoassay were defined as having CDI. Clinical data (eg, demographics, comorbidities, medication, laboratory results, and clinical outcomes were evaluated, and multivariate analysis was used to identify risk factors that were associated with recurrent CDI.Results: Seventy-six health care facility-onset CDI cases were identified, with an incidence rate of 0.8 cases per 10,000 patient-days. Fourteen cases (18.4% were recurrent, with 13 patients having experienced a single recurrent episode and one patient having experienced three recurrent episodes. The 30-day and 90-day mortality rates were 7.9% and 14.5%, respectively. Multivariate analysis revealed that recurrent patients were more likely to have underlying malignant disease (odds ratio: 7.98; 95% confidence interval: 1.22–52.2; P=0.03 and a history of intensive care unit hospitalization (odds ratio: 49.9; 95% confidence interval: 1.01–2,470; P=0.049.Conclusion: Intensive care unit hospitalization and malignancy are risk factors for recurrent

The objective of the study was to estimate the length of stay of patients with hospital-acquired infections hospitalized in ICUs using a multistate model. Active prospective surveillance of hospital-acquired infection from January 1, 1995, to December 31, 2012. Twelve ICUs at the University of Lyon hospital (France). Adult patients age greater than or equal to 18 years old and hospitalized greater than or equal to 2 days were included in the surveillance. All hospital-acquired infections (pneumonia, bacteremia, and urinary tract infection) occurring during ICU stay were collected. None. The competitive risks of in-hospital death, transfer, or discharge were considered in estimating the change in length of stay due to infection(s), using a multistate model, time of infection onset. Thirty-three thousand four-hundred forty-nine patients were involved, with an overall hospital-acquired infection attack rate of 15.5% (n = 5,176). Mean length of stay was 27.4 (± 18.3) days in patients with hospital-acquired infection and 7.3 (± 7.6) days in patients without hospital-acquired infection. A multistate model-estimated mean found an increase in length of stay by 5.0 days (95% CI, 4.6-5.4 d). The extra length of stay increased with the number of infected site and was higher for patients discharged alive from ICU. No increased length of stay was found for patients presenting late-onset hospital-acquired infection, more than the 25th day after admission. An increase length of stay of 5 days attributable to hospital-acquired infection in the ICU was estimated using a multistate model in a prospective surveillance study in France. The dose-response relationship between the number of hospitalacquired infection and length of stay and the impact of early-stage hospital-acquired infection may strengthen attention for clinicians to focus interventions on early preventions of hospital-acquired infection in ICU.

The present study surveyed demographic and infection data which were obtained after open heart surgery (OHS) through patient's admission in Golestan teaching hospital, Ahvaz metropolitan city of Iran, taking into account the confirmed location of the infection, microorganism and antibiotic susceptibility. The occurrence of infection among patients during 48 to 72 h after surgery and hospital admission is the definition of Nosocomial infections (NIs) (Salmanzadeh et al., 2015) [1]. All of them after OHS were chosen for this study. In this paper, type of catheter, fever, type of microorganism, antibiotic susceptibility, location of the infection and outcome (live or death) were studied (Juhl et al., 2017; Salsano et al., 2017) [2], [3]. After the completion of the observations and recording patients' medical records, the coded data were fed into EXCELL. Data analysis was performed using SPSS 16.

There is evidence that meticillin-resistant Staphylococcus aureus (MRSA) bacteraemia can be reduced with improved infection control and antibiotic stewardship. To survey infection control and antibiotic stewardship practices within European hospitals and to identify initiatives that correlate with reduced MRSA prevalence. Online questionnaires were sent to European hospitals about their surveillance, hand hygiene, intravenous device management, admission screening, isolation, antibiotic prescribing, hospital demographics and MRSA blood culture isolates during 2010. In all, 269 replies were received from hospitals in 29 European countries. Lower MRSA prevalence showed significant association with presence of incidence surveillance, performance of root cause analysis, mandatory training requirements for hand hygiene, accountability measures for persistent non-compliance, and multi-stakeholder teamwork in antibiotic prescribing. Presence of policies on intravenous catheter insertion and management showed no variation between different MRSA prevalence groups. However, low-prevalence hospitals reported more competency assessment programmes in insertion and maintenance of peripheral and central venous catheters. Hospitals from the UK and Ireland reported the highest uptake of infection control and antibiotic stewardship practices that were significantly associated with low MRSA prevalence, whereas Southern European hospitals exhibited the lowest. In multiple regression analysis, isolation of high-risk patients, performance of root cause analysis, obligatory training for nurses in hand hygiene, and undertaking joint ward rounds including microbiologists and infectious disease physicians remained significantly associated with lower MRSA prevalence. Proactive infection control and antibiotic stewardship initiatives that instilled accountability, ownership, teamwork, and validated competence among healthcare workers were associated with improved MRSA outcomes.

The recognized international organizations on infection prevention recommend using an observational method as the gold standard procedure for assessing health care professional's compliance with standard infection control practices. However, observational studies are rarely used in Jordanian infection control studies. This study aimed to evaluate injection practices among nurses working in Jordanian governmental hospitals. A cross-sectional concealed observational design is used for this study. A convenience sampling technique was used to recruit a sample of nurses working in governmental hospitals in Jordan. Participants were unaware of the time and observer during the observation episode. A total of 384 nurses from 9 different hospitals participated in the study. A total of 835 injections events were observed, of which 73.9% were performed without handwashing, 64.5% without gloving, and 27.5% were followed by needle recapping. Handwashing rate was the lowest (18.9%) when injections were performed by beginner nurses. Subcutaneous injections were associated with the lowest rate (26.7%) of postinjection handwashing compared with other routes. This study demonstrates the need for focused and effective infection control educational programs in Jordanian hospitals. Future studies should consider exploring the whole infection control practices related to waste disposal and the roles of the infection control nurse in this process in Jordanian hospitals.

Numerous initiatives have focused on reducing device-associated infections, contributing to an overall decrease in infections nationwide. To better understand factors associated with this decline, we assessed the use of key practices to prevent device-associated infections by US acute care hospitals from 2005 to 2013. We mailed surveys to infection preventionists at a national random sample of ∼600 US acute care hospitals in 2005, 2009 and 2013. Our survey asked about the use of practices to prevent the 3 most common device-associated infections: central line-associated bloodstream infection (CLABSI), ventilator-associated pneumonia (VAP) and catheter-associated urinary tract infection (CAUTI). Using sample weights, we estimated the per cent of hospitals reporting regular use (a score of 4 or 5 on a scale from 1 (never use) to 5 (always use)) of prevention practices from 2005 to 2013. The response rate was about 70% in all 3 periods. Use of most recommended prevention practices increased significantly over time. Among those showing the greatest increase were use of an antimicrobial dressing for preventing CLABSI (25-78%, ppreventing VAP (41-79%, ppreventing CAUTI (9-53%, pinfections. Practices for which little change was observed included use of antimicrobial catheters to prevent either CLABSI or CAUTI. US hospitals have responded to the call to reduce infection by increasing use of key recommended practices. Vigilance is needed to ensure sustained improvement and additional strategies may still be required, given an apparent continuing lag in CAUTI prevention efforts.

Prevention of common healthcare-associated infections in humanitarian hospitals.

Science.gov (United States)

Murphy, Richard A; Chua, Arlene C

2016-08-01

Humanitarian medical organizations focus on vulnerable patients with increased risk for healthcare-associated infections (HAIs) and are obligated to minimize them in inpatient departments (IPDs). However, in doing so humanitarian groups face considerable obstacles. This report will focus on approaches to reducing common HAIs that the authors have found to be helpful in humanitarian settings. HAIs are common in humanitarian contexts but there are few interventions or guidelines adapted for use in poor and conflict-affected settings to improve prevention and guide surveillance. Based on existing recommendations and studies, it appears prudent that all humanitarian IPDs introduce a basic infection prevention infrastructure, assure high adherence to hand hygiene with wide accessibility to alcohol-based hand rub, and develop pragmatic surveillance based on clinically evident nosocomial infection. Although microbiology remains out of reach for most humanitarian hospitals, rapid tests offer the possibility of improving the diagnosis of HAIs in humanitarian hospitals in the decade ahead. There is a dearth of new studies that can direct efforts to prevent HAIs in IPDs in poor and conflict-affected areas and there is a need for practical, field-adapted guidelines from professional societies, and international bodies to guide infection prevention efforts in humanitarian environments.

Effectiveness of hospital-wide methicillin-resistant Staphylococcus aureus (MRSA infection control policies differs by ward specialty.

Directory of Open Access Journals (Sweden)

Rosemarie Sadsad

Full Text Available Methicillin-resistant Staphylococcus aureus (MRSA is a major cause of preventable nosocomial infections and is endemic in hospitals worldwide. The effectiveness of infection control policies varies significantly across hospital settings. The impact of the hospital context towards the rate of nosocomial MRSA infections and the success of infection control is understudied. We conducted a modelling study to evaluate several infection control policies in surgical, intensive care, and medical ward specialties, each with distinct ward conditions and policies, of a tertiary public hospital in Sydney, Australia. We reconfirm hand hygiene as the most successful policy and find it to be necessary for the success of other policies. Active screening for MRSA, patient isolation in single-bed rooms, and additional staffing were found to be less effective. Across these ward specialties, MRSA transmission risk varied by 13% and reductions in the prevalence and nosocomial incidence rate of MRSA due to infection control policies varied by up to 45%. Different levels of infection control were required to reduce and control nosocomial MRSA infections for each ward specialty. Infection control policies and policy targets should be specific for the ward and context of the hospital. The model we developed is generic and can be calibrated to represent different ward settings and pathogens transmitted between patients indirectly through health care workers. This can aid the timely and cost effective design of synergistic and context specific infection control policies.

Why sensitive bacteria are resistant to hospital infection control [version 2; referees: 2 approved

Esther van Kleef

2017-11-01

Full Text Available Background: Large reductions in the incidence of antibiotic-resistant strains of Staphylococcus aureus and Clostridium difficile have been observed in response to multifaceted hospital-based interventions. Reductions in antibiotic-sensitive strains have been smaller or non-existent. It has been argued that since infection control measures, such as hand hygiene, should affect resistant and sensitive strains equally, observed changes must have largely resulted from other factors, including changes in antibiotic use. We used a mathematical model to test the validity of this reasoning. Methods: We developed a mechanistic model of resistant and sensitive strains in a hospital and its catchment area. We assumed the resistant strain had a competitive advantage in the hospital and the sensitive strain an advantage in the community. We simulated a hospital hand hygiene intervention that directly affected resistant and sensitive strains equally. The annual incidence rate ratio (IRR associated with the intervention was calculated for hospital- and community-acquired infections of both strains. Results: For the resistant strain, there were large reductions in hospital-acquired infections (0.1 ≤ IRR ≤ 0.6 and smaller reductions in community-acquired infections (0.2 ≤ IRR ≤  0.9. These reductions increased in line with increasing importance of nosocomial transmission of the strain. For the sensitive strain, reductions in hospital acquisitions were much smaller (0.6 ≤ IRR ≤ 0.9, while communityacquisitions could increase or decrease (0.9 ≤ IRR ≤ 1.2. The greater the importance of the community environment for the transmission of the sensitive strain, the smaller the reductions. Conclusions: Counter-intuitively, infection control interventions, including hand hygiene, can have strikingly discordant effects on resistant and sensitive strains even though they target them equally, following differences in their adaptation to hospital and

Full Text Available Abstract Background Healthcare acquired infections (HAI are an important public health problem in developed countries, but comprehensive data on trends over time are lacking. Prevalence surveys have been used as a surrogate for incidence studies and can be readily repeated. Methods The Canadian Nosocomial Infection Surveillance Program conducted prevalence surveys in 2002 and 2009 in a large network of major Canadian acute care hospitals. NHSN definitions of HAI were used. Use of isolation precautions on the survey day was documented. Results In 2009, 9,953 acute care inpatients were surveyed; 1,234 infections (124/1000 were found, compared to 111/1000 in 2002, (p < 0.0001. There was increased prevalence of urinary tract infection (UTI and Clostridium difficile, offset by decreases in pneumonia and bloodstream infection. Use of isolation precautions increased from 77 to 148 per 1000 patients (p < 0.0001, attributable to increased use of contact precautions in patients infected or colonized with antimicrobial resistant organisms. Conclusion Between 2002 and 2009 HAI prevalence increased by 11.7 % in a network of major Canadian hospitals due to increases in Clostridium difficile and urinary tract infection. The use of isolation precautions increased by 92.2 % attributable to increased contact isolation. National prevalence surveys are useful tools to assess evolving trends in HAI.

Human coronavirus (HCoV) NL63 is recognized in association with upper or lower respiratory tract illnesses in children. This study surveyed the prevalence of HCoV-NL63 and influenza viruses in patients with influenza-like illness in Taiwan during 2010-2011. Throat samples from 107 hospitalized patients with pneumonia and 175 outpatients with influenza-like illness were examined using real-time polymerase chain reaction assays with virus-specific primers, and then virus-positive specimens were confirmed by sequencing the polymerase chain reaction products. HCoV-NL63 infection was identified in 8.4% (9/107) of hospitalized patients with pneumonia, but not found in outpatients with influenza-like illness. Age distribution of HCoV-NL63 infection in hospitalized patients with pneumonia indicated that the group aged 16-25 years (20%) had the highest positive rate compared with the other groups, and exhibited a similar age-specific pattern to influenza A/H1N1 infection, but not influenza A/H3N2 and B infections in hospitalized patients. Seasonal prevalence of HCoV-NL63 infection was late winter, overlapping the highest peak of the influenza A/H1N1 epidemic during December 2010 to March 2011 in Taiwan. Co-infection of HCoV-NL63 and influenza A/H1N1 was detected in three hospitalized patients. Clinical manifestation analysis indicated that the main symptoms for HCoV-NL63 infection included fever (88.9%), cough (77.8%), and pneumonia (100%). Co-infection caused significantly higher rates of breathing difficulties, cough, and sore throat than those of single infection with HCoV-NL63 and influenza A/H1N1. Phylogenetic analysis indicated a low level of heterogeneity between Taiwan and global HCoV-NL63 strains. Understanding epidemiology of HCoV-NL63 in Taiwan provides an insight for worldwide surveillance of HCoV-NL63 infection. Copyright © 2015. Published by Elsevier B.V.

In spite of decreasing incidence of orthopedic device-related infections to 1%, nowadays, device-related infection still remains a diagnostic, therapeutic and cost-related problem. The objective of this study is to evaluate the contributing risk factors for orthopedic device-related infections in Sina Hospital, Tehran, Iran. Three hundred and thirty patients who underwent orthopedic device implantation from 2002-2006 were enrolled; among them, 110 patients were complicated with infection. Descriptive and logistic regression analyses were performed to determine the risk factors for device related infections. Patients with infection were older compared to those without infection. The Staphylococcus aureus was the commonest organism. A correlation was observed between wound infection and external fixation, an underlying health condition, and addiction which were independent risk factors for a device related infection. Orthopedic device-related infection puts a great financial burden on patients and hospital resources and could lead to morbidity and mortality in patients. So, appropriate pre and postoperative wound care for dirty wounds, especially when external fixators are used, and in patients with poor conditions or addiction should be done with more caution.

Hospital Textiles, Are They a Possible Vehicle for Healthcare-Associated Infections?

Directory of Open Access Journals (Sweden)

Sabina Fijan

2012-09-01

Full Text Available Textiles are a common material in healthcare facilities; therefore it is important that they do not pose as a vehicle for the transfer of pathogens to patients or hospital workers. During the course of use hospital textiles become contaminated and laundering is necessary. Laundering of healthcare textiles is most commonly adequate, but in some instances, due to inappropriate disinfection or subsequent recontamination, the textiles may become a contaminated inanimate surface with the possibility to transfer pathogens. In this review we searched the published literature in order to answer four review questions: (1 Are there any reports on the survival of microorganisms on hospital textiles after laundering? (2 Are there any reports that indicate the presence of microorganisms on hospital textiles during use? (3 Are there any reports that microorganisms on textiles are a possible source infection of patients? (4 Are there any reports that microorganisms on textiles are a possible source infection for healthcare workers?

The main objective of this study was to explore the prevalence and clinical characteristics of human coronavirus NL63 infection in hospitalized children with acute lower respiratory tract infection (ALRTI) in Changsha. Nasopharyngeal aspirates (NPA) samples were collected from 1185 hospitalized children with ALRTI at the People's Hospital of Hunan province, between September 2008 and October 2010. Reverse transcriptase polymerase chain reaction (RT-PCR) was employed to screen for coronavirus NL63, which is a 255 bp fragment of a part of N gene. All positive amplification products were confirmed by sequencing and compared with those in GenBank. The overall frequency of coronavirus NL63 infection was 0.8%, 6 (60%) out of the coronavirus NL63 positive patients were detected in summer, 2 in autumn, 1 in spring and winter, respectively. The patients were from 2 months to two and a half years old. The clinical diagnosis was bronchopneumonia (60%), bronchiolitis (30%), and acute laryngotracheal bronchitis (10%). Four of the 10 cases had critical illness, 4 cases had underlying diseases, and 7 cases had mixed infection with other viruses. The homogeneity of coronavirus NL63 with those published in the GenBank at nucleotide levels was 97%-100%. Coronavirus NL63 infection exists in hospitalized children with acute lower respiratory tract infection in Changsha. Coronavirus NL63 infections are common in children under 3 years of age. There is significant difference in the infection rate between the boys and the girls: the boys had higher rate than the girls. The peak of prevalence of the coronavirus NL63 was in summer. A single genetic lineage of coronavirus NL63 was revealed in human subjects in Changsha. Coronavirus NL63 may also be one of the lower respiratory pathogen in China.

The focus of nursing home infection control procedures has been on decreasing transmission between healthcare workers and residents. Less evidence is available regarding whether decontamination of high-touch environmental surfaces impacts infection rates or resident outcomes. The purpose of this study was to examine if ultraviolet disinfection is associated with changes in: 1) microbial counts and adenosine triphosphate counts on high-touch surfaces; and 2) facility wide nursing home acquired infection rates, and infection-related hospitalization. The study was conducted in one 160-bed long-term care facility. Following discharge of each resident, their room was cleaned and then disinfected using a newly acquired ultraviolet light disinfection device. Shared living spaces received weekly ultraviolet light disinfection. Thirty-six months of pretest infection and hospitalization data were compared with 12 months of posttest data. Pre and posttest cultures were taken from high-touch surfaces, and luminometer readings of adenosine triphosphate were done. Nursing home acquired infection rates were analyzed relative to hospital acquired infection rates using analysis of variance procedures. Wilcoxon signed rank tests, The Cochran's Q, and Chi Square were also used. There were statistically significant decreases in adenosine triphosphate readings on all high-touch surfaces after cleaning and disinfection. Culture results were positive for gram-positive cocci or rods on 33% (n = 30) of the 90 surfaces swabbed at baseline. After disinfectant cleaning, 6 of 90 samples (7.1%) tested positive for a gram-positive bacilli, and after ultraviolet disinfection 4 of the 90 samples (4.4%) were positive. There were significant decreases in nursing home acquired relative to hospital-acquired infection rates for the total infections (p = .004), urinary tract infection rates (p = .014), respiratory system infection rates (p = .017) and for rates of infection of the skin

Full Text Available Plasmodium malariae is a slow-growing parasite with a wide geographic distribution. Although generally regarded as a benign cause of malaria, it has been associated with nephrotic syndrome, particularly in young children, and can persist in the host for years. Morbidity associated with P. malariae infection has received relatively little attention, and the risk of P. malariae-associated nephrotic syndrome is unknown.We used data from a very large hospital-based surveillance system incorporating information on clinical diagnoses, blood cell parameters and treatment to describe the demographic distribution, morbidity and mortality associated with P. malariae infection in southern Papua, Indonesia. Between April 2004 and December 2013 there were 1,054,674 patient presentations to Mitra Masyarakat Hospital of which 196,380 (18.6% were associated with malaria and 5,097 were with P. malariae infection (constituting 2.6% of all malaria cases. The proportion of malaria cases attributable to P. malariae increased with age from 0.9% for patients under one year old to 3.1% for patients older than 15 years. Overall, 8.5% of patients with P. malariae infection required admission to hospital and the median length of stay for these patients was 2.5 days (Interquartile Range: 2.0-4.0 days. Patients with P. malariae infection had a lower mean hemoglobin concentration (9.0 g/dL than patients with P. falciparum (9.5 g/dL, P. vivax (9.6g/dL and mixed species infections (9.3g/dL. There were four cases of nephrotic syndrome recorded in patients with P. malariae infection, three of which were in children younger than 5 years old, giving a risk in this age group of 0.47% (95% Confidence Interval; 0.10% to 1.4%. Overall, 2.4% (n = 16 of patients hospitalized with P. malariae infection subsequently died in hospital, similar to the proportions for the other endemic Plasmodium species (range: 0% for P. ovale to 1.6% for P. falciparum.Plasmodium malariae infection is

Objective: To determine the percentage and frequency of Methicillin Resistant Staphylococcus aureus in community and hospital-acquired pyogenic skin and soft tissue infections. Methods: The descriptive cross-sectional study was conducted at the Dermatology Department of Combined Military Hospital, Abbottabad, from June 2009 to March 2010, and comprised 144 community-acquired and 54 hospital-acquired skin and soft tissue infections. Pus swabs from the infected lesions one from each individual were sent to laboratory for culture and sensitivity tests. Methicillin resistance was detected by 1 (mu) g oxacillin disk. Organisms were labelled methicillin-resistant once the inhibition zone for oxocillin was less than 10 mm. Data analysis was done by using SPSS 20. Results: Of the 198 patients in the study, 98(49.5%) were males and 100(50.5%) were females, with an overall mean age of 33.7+-14.8144 years. There were 144(72.72%) community-acquired infections and 54(27.27%) had hospital-acquired infections. Community-acquired Methicillin Resistant Staphylococcus aureus numbered 40(27.8%) and hospital-acquired ones numbered 26(48.1%). Conclusion: Prevalence of Methicillin Resistant Staphylococcus aureus in community and hospital-acquired pyogenic skin and soft tissue infections was high. (author)

To validate the construct and discriminant properties of a hospital infection prevention and control program. The program consisted of four indicators: technical-operational structure; operational prevention and control guidelines; epidemiological surveillance system; and prevention and control activities. These indicators, with previously validated content, were applied to 50 healthcare institutions in the city of São Paulo, Southeastern Brazil, in 2009. Descriptive statistics were used to characterize the hospitals and indicator scores, and Cronbach's α coefficient was used to evaluate the internal consistency. The discriminant validity was analyzed by comparing indicator scores between groups of hospitals: with versus without quality certification. The construct validity analysis was based on exploratory factor analysis with a tetrachoric correlation matrix. The indicators for the technical-operational structure and epidemiological surveillance presented almost 100% conformity in the whole sample. The indicators for the operational prevention and control guidelines and the prevention and control activities presented internal consistency ranging from 0.67 to 0.80. The discriminant validity of these indicators indicated higher and statistically significant mean conformity scores among the group of institutions with healthcare certification or accreditation processes. In the construct validation, two dimensions were identified for the operational prevention and control guidelines: recommendations for preventing hospital infection and recommendations for standardizing prophylaxis procedures, with good correlation between the analysis units that formed the guidelines. The same was found for the prevention and control activities: interfaces with treatment units and support units were identified. Validation of the measurement properties of the hospital infection prevention and control program indicators made it possible to develop a tool for evaluating these programs

With the rapid development of the Internet, both digitization and electronic orientation are required on various applications in the daily life. For hospital-acquired infection control, a Web-based Hospital-acquired Infection Surveillance System was implemented. Clinical data from different hospitals and systems were collected and analyzed. The hospital-acquired infection screening rules in this system utilized this information to detect different patterns of defined hospital-acquired infection. Moreover, these data were integrated into the user interface of a signal entry point to assist physicians and healthcare providers in making decisions. Based on Service-Oriented Architecture, web-service techniques which were suitable for integrating heterogeneous platforms, protocols, and applications, were used. In summary, this system simplifies the workflow of hospital infection control and improves the healthcare quality. However, it is probable for attackers to intercept the process of data transmission or access to the user interface. To tackle the illegal access and to prevent the information from being stolen during transmission over the insecure Internet, a password-based user authentication scheme is proposed for information integrity.

Nosocomial infection (i.e. infection in healthcare facilities) raises a serious public health problem, as implied by the existence of pathogens characteristic to healthcare facilities such as methicillin-resistant Staphylococcus aureus and hospital-mediated outbreaks of influenza and severe acute respiratory syndrome. For general communities, epidemic modeling based on social networks is being recognized as a useful tool. However, disease propagation may occur in a healthcare facility in a manner different from that in a urban community setting due to different network architecture. We simulate stochastic susceptible-infected-recovered dynamics on social networks, which are based on observations in a hospital in Tokyo, to explore effective containment strategies against nosocomial infection. The observed social networks in the hospital have hierarchical and modular structure in which dense substructure such as departments, wards, and rooms, are globally but only loosely connected, and do not reveal extremely right-skewed distributions of the number of contacts per individual. We show that healthcare workers, particularly medical doctors, are main vectors (i.e. transmitters) of diseases on these networks. Intervention methods that restrict interaction between medical doctors and their visits to different wards shrink the final epidemic size more than intervention methods that directly protect patients, such as isolating patients in single rooms. By the same token, vaccinating doctors with priority rather than patients or nurses is more effective. Finally, vaccinating individuals with large betweenness centrality (frequency of mediating connection between pairs of individuals along the shortest paths) is superior to vaccinating ones with large connectedness to others or randomly chosen individuals, which was suggested by previous model studies.

Full Text Available The importance of the environment as a reservoir for microorganisms implicated in disease transmission in the hospital setting has been increasingly recognized, especially with respect to dialysis units, ventilation in specialized areas, and the proper use of disinfectants (1. Inherent within the environmental setting is the importance of physical plant design. Several studies have underscored the importance of optimizing design standards to maximize patient and health care worker (HCW safety, including the prevention of hospital-acquired infections in patients (2-6. Ulrich et al (7 recently completed an evidence-based review, entitled 'The role of the physical environment in the hospital of the 21st century: A once-in-a-lifetime opportunity', for the Center for Health Design in California (USA, which was funded by the Robert Wood Johnson Foundation. Ulrich and colleagues identified over 600 studies that examined the hospital environment and its effects on staff effectiveness, patient safety, patient and family stress, quality and costs. They suggested that one of the important elements in improving patient safety is the reduction of the risk of hospital-acquired infections through improved facility design.

Nosocomial infection control is crucial for improving the quality of medical care. It is also indispensable for implementing effective control measures for severe acute respiratory syndrome (SARS) and the possible occurrence of a human influenza pandemic. The present authors, in collaboration with Vietnamese hospital staff, performed a fact-finding survey of nosocomial infection control in hospitals in northern Vietnam and compared the results with those of a survey conducted 4 years previously. Remarkable improvement was recognized in this period, although there were considerable differences between the central hospitals in Hanoi and local hospitals. In the local hospitals, basic techniques and the systems for infection control were regarded as insufficient, and it is necessary to improve these techniques and systems under the guidance of hospitals in the central area. Based on the results of the survey, programs were prepared and training courses were organized in local hospitals. Evaluation conducted after the training courses showed a high degree of satisfaction among the trainees. The results of the survey and the training courses conducted during the study period are expected to contribute to the improvement of nosocomial infection control in remote areas of Vietnam.

Clostridium difficile infection (CDI) is increasingly being found in populations without traditional risk factors. We compared the relative frequency, risk factors, severity, and outcomes of community-onset CDI with hospital-acquired infection. This was a retrospective, observational study of CDI at a tertiary hospital campus in Sydney, Australia. Patients aged 15 years and older with a first episode of CDI from January 1 to December 31, 2011 were included. CDI was defined as the presence of diarrhoea with a positive enzyme immunoassay in conjunction with a positive cell cytotoxicity assay, toxin culture, or organism culture. Main outcome measures were onset of infection (hospital or community), risk factors, markers of severity, and outcomes for the two groups. One hundred and twenty-nine cases of CDI infection were identified, of which 38 (29%) were community-onset. The community-onset infection group were less likely to have a recent history of antibiotic use (66% vs. 98%; pinfection group. Markers of severity and outcomes were similar in the two groups, with an overall mortality of 9%. Community-onset CDI accounts for a large proportion of C. difficile infections and has a similar potential for severe disease as hospital-acquired infection. Using a history of previous antibiotic use, proton pump inhibitor use, or recent hospitalization to predict cases is unreliable. We recommend that patients with diarrhoea being investigated in emergency departments and community practice are tested for Clostridium difficile infection. Crown Copyright © 2014.

Full Text Available Background. More than 50,000 cases of acute gastroenteritis are registered in children in Ukraine annually. Statistical data concerning rotavirus infection are not correct due to poor capacities of rotavirus laboratory diagnostics in medical units. The aim of the study was to estimate rotavirus infection burden, to analyze and describe rotavirus infection in children aged under 5 years old who were hospitalized into two infectious hospitals (Kyiv and Odessa within 2006–2015 period. Material and Methods. Investigation was carried according to a standard protocol, adopted by WHO. The disease severity was estimated by score scale for clinical manifestations of rotavirus gastroenteritis assessment of Vesikari. Results. At the period from December 2006 to December 2015 20,932 children aged under 5 years old were observed. Those children admitted to hospitals of infectious diseases in Kyiv and Odessa for acute gastroenteritis and met studies inclusive criteria. From them 18,384 (87.33 % children were investigated for rotavirus, i.e. wide majority of all children admitted to hospitals with gastroenteritis. The cause of their hospitalization was rotavirus infection in almost half of all children. It was mentioned that in some periods hospitalization rate for rotavirus as a cause of gastroenteritis was up to 70 % of all cases. In Ukraine incidence of rotavirus diarrhea in hospitalized children up to 5 years old was the highest one among 6 countries of the European region included into Global Rotavirus Surveillance Network. In Ukraine it was 41 % and the region mean value was 24 %. Within the total period of observation half of all hospitalizations caused by rotavirus occurred in children of first two years of life. All time the main viruses causing infection in both hospitals were of 4 genotypes: G1P[8], G2P[4], G3P[8], G4P[8]. Genotype G9P[8] possessed a significant position in Kyiv, but there were years, when it was not identified neither in Kyiv

Limitations in methods for the rapid diagnosis of hospital-acquired infections often delay initiation of effective antimicrobial therapy. New diagnostic approaches offer potential clinical and cost-related improvements in the management of these infections. We developed a decision modeling framework to assess the potential cost-effectiveness of a rapid biomarker assay to identify hospital-acquired infection in high-risk patients earlier than standard diagnostic testing. The framework includes parameters representing rates of infection, rates of delayed appropriate therapy, and impact of delayed therapy on mortality, along with assumptions about diagnostic test characteristics and their impact on delayed therapy and length of stay. Parameter estimates were based on contemporary, published studies and supplemented with data from a four-site, observational, clinical study. Extensive sensitivity analyses were performed. The base-case analysis assumed 17.6% of ventilated patients and 11.2% of nonventilated patients develop hospital-acquired infection and that 28.7% of patients with hospital-acquired infection experience delays in appropriate antibiotic therapy with standard care. We assumed this percentage decreased by 50% (to 14.4%) among patients with true-positive results and increased by 50% (to 43.1%) among patients with false-negative results using a hypothetical biomarker assay. Cost of testing was set at $110/d. In the base-case analysis, among ventilated patients, daily diagnostic testing starting on admission reduced inpatient mortality from 12.3 to 11.9% and increased mean costs by $1,640 per patient, resulting in an incremental cost-effectiveness ratio of $21,389 per life-year saved. Among nonventilated patients, inpatient mortality decreased from 7.3 to 7.1% and costs increased by $1,381 with diagnostic testing. The resulting incremental cost-effectiveness ratio was $42,325 per life-year saved. Threshold analyses revealed the probabilities of developing

The first outbreak of methicillin-resistant Staphylococcus aureus (MRSA) infection in horses in Sweden occurred in 2008 at the University Animal Hospital and highlighted the need for improved infection prevention and control. The present study describes interventions and infection prevention control in an equine hospital setting July 2008 - April 2010. This descriptive study of interventions is based on examination of policy documents, medical records, notes from meetings and cost estimates. MRSA cases were identified through clinical sampling and telephone enquiries about horses post-surgery. Prospective sampling in the hospital environment with culture for MRSA and genotyping of isolates by spa-typing and pulsed-field gel electrophoresis (PFGE) were performed. Interventions focused on interruption of indirect contact spread of MRSA between horses via staff and equipment and included: Temporary suspension of elective surgery; and identification and isolation of MRSA-infected horses; collaboration was initiated between authorities in animal and human public health, human medicine infection control and the veterinary hospital; extensive cleaning and disinfection was performed; basic hygiene and cleaning policies, staff training, equipment modification and interior renovation were implemented over seven months.Ten (11%) of 92 surfaces sampled between July 2008 and April 2010 tested positive for MRSA spa-type 011, seven of which were from the first of nine sampling occasions. PFGE typing showed the isolates to be the outbreak strain (9 of 10) or a closely related strain. Two new cases of MRSA infection occurred 14 and 19 months later, but had no proven connections to the outbreak cases. Collaboration between relevant authorities and the veterinary hospital and formation of an infection control committee with an executive working group were required to move the intervention process forward. Support from hospital management and the dedication of staff were essential for

Provision of information plays a critical role in supporting patients to be engaged or empowered to be involved with infection prevention measures in hospitals. This explorative study evaluated the suitability, readability and accessibility of information on healthcare associated infections (HCAIs) and infection prevention strategies targeted at patients from the websites of 19 acute care public hospitals in Sydney, Australia. We included hospitals with greater than 200 beds in the sample. We examined online information targeted at patients on HCAIs and infection prevention and compared it using the Suitability Assessment of Material (SAM) and Simple Measure of Gobbledygook (SMOG) readability formulas for suitability, readability and accessibility. Thirty-six webpages were identified as being relevant and containing information about HCAIs or infection prevention. Based on the SAM/SMOG scores, only three webpages were found to be 'superior'. Many of the webpages scored poorly in content, literacy, graphics, learning stimulation and cultural appropriateness. In comparison, most of the webpages scored well in the layout and typography. The majority (97%) of the materials were written at a level higher than the recommended reading grade level. Lastly, the websites scored poorly on the ability to locate the information easily, as messages about HCAIs/infection prevention were usually embedded into other topics. While providing information online is only one approach to delivering messages about infection prevention, it is becoming increasingly important in today's technology society. Hospitals are neglecting to use best practices when designing their online resources and current websites are difficult to navigate. The findings point to the need to review patient information on HCAIs regarding suitability, readability and accessibility.

Infective endocarditis is a serious infection, often resulting from injection drug use. Inpatient treatment regularly focuses on management of infection without attention to the underlying addiction. We aimed to determine the addiction interventions done in patients hospitalized with injection drug use-associated infective endocarditis. This is a retrospective review of patients hospitalized with injection drug use-associated infective endocarditis from January, 2004 through August, 2014 at a large academic tertiary care center in Boston, Massachusetts. For the initial and subsequent admissions, data were collected regarding addiction interventions, including consultation by social work, addiction clinical nurse and psychiatry, documentation of addiction in the discharge summary plan, plan for medication-assisted treatment and naloxone provision. There were 102 patients admitted with injection drug use-associated infective endocarditis, 50 patients (49.0%) were readmitted and 28 (27.5%) patients had ongoing injection drug use at readmission. At initial admission, 86.4% of patients had social work consultation, 23.7% had addiction consultation, and 24.0% had psychiatry consultation. Addiction was mentioned in 55.9% of discharge summary plans, 7.8% of patients had a plan for medication-assisted treatment, and naloxone was never prescribed. Of 102 patients, 26 (25.5%) are deceased. The median age at death was 40.9 years (interquartile range 28.7-48.7). We found that patients hospitalized with injection drug use-associated infective endocarditis had high rates of readmission, recurrent infective endocarditis and death. Despite this, addiction interventions were suboptimal. Improved addiction interventions are imperative in the treatment of injection drug use-associated infective endocarditis.

Factors affecting infection are the existence of infectious microorganisms, sensitivity of hosts, number of microorganisms, and infectious routes. Efforts to prevent infection focus on not allowing these factors to reach the threshold level. Inspection by an infection control team (ICT) of a hospital is one countermeasure for preventing nosocomial infection. We summarize here the problems for complete prevention of nosocomial infection based on the results of inspection by our ICT, so that staff working in the hospital can recognize the importance of preventing nosocomial infection. The following were commonly observed problems in our clinics found by the ICT : (1) incomplete practice of standard precautions and/or isolation precautions, (2) noncompliance with guidelines for the prevention of cross-infection, and (3) inappropriate management of medical rejectamenta. Infection control can be accomplished by strictly observing the standard precautions and isolation precautions. The ICT inspection round in the hospital could be an effective metaff working in the hod to clarify and overcome the problems involved in infection.

The "hospital-at-home" model may provide adequate care without an adverse effect on clinical outcome, and is generally well received by users. Our objective was to compare hospital-at-home and in-patient hospital care for neuromuscular disease (NMD) patients with respiratory tract infections. We conducted a prospective randomized controlled trial in a university teaching hospital offering secondary care service to a population of approximately 500,000. We recruited selected NMD patients with respiratory tract infection for whom hospital admission had been recommended after medical assessment. Hospital-at-home was provided as an alternative to in-patient admission. The main outcome measures were need for hospitalization, treatment failure, time to recovery, death during the first 3 months following exacerbation, and cost of patient care. Among 59 consecutive NMD patients eligible for the study, 53 met the criteria for hospital-at-home. Twenty-six subjects were randomized to home care and 27 to hospital care. No significant differences were found in treatment failure (8/26 vs 13/27, P = .19), time to recovery (8.9 ± 4.6 vs 9 ± 8.9 d, P = .21), or mortality at 3 months (3/26 vs 4/27 deaths, P = .42) between the groups. Hospital-at-home failure was independently correlated with type of NMD (P = .004) with an odds ratio of failure of 17.3 (95% CI 2.1 to infinity) for subjects with amyotrophic lateral sclerosis. The total and daily direct cost of patient healthcare was significantly lower for the subjects who were successfully treated at home, compared to the hospitalized individuals. Hospital-at-home is an effective alternative to hospital admission for selected NMD patients with respiratory tract infections.

To determine the epidemiology of rotavirus gastroenteritis in children admitted to an urban hospital in a developing country from South-East Asia. Retrospective review of cases of acute gastroenteritis admitted to the children's ward of the University of Malaya Medical Centre, Kuala Lumpur, Malaysia, between 1996 and 1999. During the study period, 333 cases (24%) of 1362 stool samples, obtained from children admitted with acute diarrhoea, were positive for rotavirus. Acute gastroenteritis constituted 8.2%, and rotavirus infection 1.6% of all the paediatric admissions each year. Of the 271 cases analysed, 72% of the affected population were less than 2 years of age. Peak incidence of admissions was between January to March, and September to October. Dehydration was common (92%) but electrolyte disturbances, lactose intolerance (5.2%), prolonged diarrhoea (2.6%) and cow's milk protein intolerance was uncommon. No deaths were recorded. Rotavirus infection was a common cause of childhood diarrhoea that required hospital admission in an urban setting in Malaysia.

Full Text Available Background: The rate of nosocomial infection appears to depend on whether it is calculated using the Center for Disease Control (CDC or carrier state criteria. The objective of this study was to differentiate between primary endogenous (PE, secondary endogenous (SE and exogenous (EX infections, and to compare this classification with CDC criteria for nosocomial infections. Methods: Children hospitalized for more than 72 h at pediatric intensive care unit during 2004–2005 were enrolled.

The rate of nosocomial infection appears to depend on whether it is calculated using the Center for Disease Control (CDC) or carrier state criteria. The objective of this study was to differentiate between primary endogenous (PE), secondary endogenous (SE) and exogenous (EX) infections, and to compare this classification with CDC criteria for nosocomial infections. Children hospitalized for more than 72 h at pediatric intensive care unit during 2004-2005 were enrolled. Children, who had the infection before the admission, and or did not develop an infection within the hospitalization were excluded. Surveillance samples were sampled on admission, and then twice a week. Diagnostic samples were obtained when infection was suspected based on the clinical condition and laboratory findings. Infections were evaluated as PE, SE and EX, and their incidences were compared with CDC criteria for nosocomial infections. One hundred seventy eight patients were enrolled in the study. Forty-four patients (24.7%) develop infection. Twenty-seven patients (61.3%) had PE, 10 patients (22.7%) had SE, and 7 patients (15.9%) had EX infection. Secondary endogenous and EX infections are considered as nosocomial, thus 17 patients (38.6%) had a nosocomial infection. Thirty-one patients (70.5%) met CDC criteria for nosocomial infections. Seventeen patients (55%) were classified as PE, and 14 patients (45%) as SE or EX infections. Seventy percent of infections (31 out of 44 patients) met the CDC criteria for nosocomial infections, but only 39% of infections (17 out of 44 patients) were classified as nosocomial based on carrier state classification.

Full Text Available Nosocomial infection are one of the main problem in hospital which are associated with significant morbidity, mortality and increased economic cost. Surveillance should be attempted regularly to obtain local data of incidence of nosocomial infections, types of infection, pathogen and resistance pattern. We reported the results of nosocomial surveillance in Dr. Cipto Mangunkusumo National General Hospital, Jakarta, in year 1999 to 2002. The data were obtained from surveillance, conducted by Nosocomial Infection Control Committee. Surveillance were performed to patient in risk of nosocomial infections such as underwent surgical procedure, urinary catheter, peripheral or central venous catheter, ventilator and other invasive procedure. Criteria for nosocomial infection which were used, based on technical guidelines of nosocomial infection in Dr. Cipto Mangunkusumo National General Hospital, year 1999; which referred to CDC definition of nosocomial infections. Incidence rate of nosocomial infections in year 1999, 2000, 2001 and 2002 were 1.1, 0.9, 0.6 and 0.4 % respectively. Type of nosocomial infection include catheter related, surgical wound, urinary tract and respiratory tract infections, ranged between 0 to 5.6 %. Gram negative bacteria consist of Pseudomonas sp, Enterobacter aerogenes, Escherichia coli, Proteus mirabilis were the most common nosocomial pathogen. Gram positive bacteria consist of Staphylococcus epidermidis, Staphylococcus aureus and Streptococcus anhemolyticus. Trend of increasing incidence of Gram positive nosocomial infection also showed in our surveillance. Mostly Gram negative bacteria had been resistant to penicillin, co amoxicillin-clavulanic acid and 3rd generation cephalosporin, but still sensitive to 4th generation cephalosporin and aminoglycoside. The Gram positive bacteria were still sensitive to penicillin, co amoxicillin-clavulanic acid, 4th generation cephalosporin and aminoglycoside. (Med J Indones 2004; 13: 107

Hospital or nosocomial infection, or infection acquired in hospitals, is a health problem in all hospital departments and particularly in the maternity department. We report on a prospective survey of surveillance of hospital-acquired infections both from the mother and the baby's point of view after delivery vaginally or with caesarean carried out at the obstetrical clinic of the Edouard Herriot Hospital in Lyon (France) over three successive years with a series of 9,204 deliveries. The incidence of infection in women who were delivered without caesarean section was 1.37% when urinary tract infections had been excluded but 13% in women who had caesarean sections. Endometritis, skin infections and urinary tract infections were the leading causes. As far as the newborn were concerned, hospital infection ran at about 2.60% and this in the main was due to staphylococcal pustules in the skin. These figures are still too high and prevention should be based on more information given and more care taken by the whole staff of such a hospital.

Minimal structure is required for effective prevention of health care-associated infection (HAI). The objective of this study was to evaluate the structure for prevention of HAI in a sample of Brazilian hospitals. This was a cross-sectional study from hospitals in 5 Brazilian regions (n = 153; total beds: 13,983) classified according to the number of beds; 11 university hospitals were used as reference for comparison. Trained nurses carried out the evaluation by using structured forms previously validated. The evaluation of conformity index (CI) included elements of structure of the Health Care-Associated Prevention and Control Committee (HAIPCC), hand hygiene, sterilization, and laboratory of microbiology. The median CI for the HAIPCC varied from 0.55-0.94 among hospital categories. Hospitals with >200 beds had the worst ratio of beds to sinks (3.9; P hospitals with hospitals (3.3; P hospitals were more likely to have their own laboratory of microbiology than other hospitals. This study highlights the need for public health strategies aiming to improve the structure for HAI prevention in Brazilian hospitals.

Objective To assess the impact of respiratory tract infection in the postoperative period of cardiac surgery in relation to mortality and to identify patients at higher risk of developing this complication. Methods Cross-sectional observational study conducted at the Recovery of Cardiothoracic Surgery, using information from a database consisting of a total of 900 patients operated on in this hospital during the period from 01/07/2008 to 1/07/2009. We included patients whose medical records contained all the information required and undergoing elective surgery, totaling 109 patients with two excluded. Patients were divided into two groups, WITH and WITHOUT respiratory tract infection, as the development or respiratory tract infection in hospital, with patients in the group without respiratory tract infection, the result of randomization, using for the pairing of the groups the type of surgery performed. The outcome variables assessed were mortality, length of hospital stay and length of stay in intensive care unit. The means of quantitative variables were compared using the Wilcoxon and student t-test. Results The groups were similar (average age P=0.17; sex P=0.94; surgery performed P=0.85-1.00) Mortality in the WITH respiratory tract infection group was significantly higher (P<0.0001). The times of hospitalization and intensive care unit were significantly higher in respiratory tract infection (P<0.0001). The presence of respiratory tract infection was associated with the development of other complications such as renal failure dialysis and stroke P<0.00001 and P=0.002 respectively. Conclusion The development of respiratory tract infection postoperative cardiac surgery is related to higher mortality, longer periods of hospitalization and intensive care unit stay. PMID:26313727

Full Text Available Introduction: Nosocomial Infections (NI are a frequent and relevant problem, in other hands; those are responsible of mortality especially in pediatric ICU( Intensive Care Unit and NICUs (Neonatal Intensive Care Unit. Healthcare-associated infections are important in wide-ranging concern in the medical field. The most cause of Nosocomial infection include: bloodstream infection, urinary tract infection, pneumonia, and wound infection. The purpose of this study was to determine the epidemiology of the three most common NI in the Pediatric department.        Materials and Methods: We performed a prospective study in a single Pediatric department during 12 months. Children were assessed for 3 NI: wound infections, pneumonia and urinary tract infections (UTI, as the same method as Center of Disease Control criteria. All patients were followed up and individuals who had have NI and their treatment was entered in this study.          Results: In this study 811 patients were hospitalized that 60% of them were male and were older than 60 months. The main causes of hospitalization include: toxicity, seizure, respiratory infection and fever. Among them 15 cases had NI (1.87%. The most NI occurred in pediatric intensive care unit (PICU and it was followed in aspect of intubation. The most cultured organism was pseudomonas that they suspected to ceftazidime and isolate from blood and endotracheal tube.           Conclusion:  NI presence was associated with increased mortality and length of stay in hospital. This study highlights the importance of NIs in children admitted to a pediatric department especially PICU in a developing country. Clinical monitoring of NIs and bacterial resistance profiles are required in all pediatric units.

Hospital-specific surgical site infection (SSI) performance following colon surgery and abdominal hysterectomies can impact hospitals' relative rankings around quality metrics used to determine financial penalties. Current SSI surveillance largely focuses on SSI detected at the operative hospital. Retrospective cohort study to assess the impact on hospitals' relative SSI performance rankings when SSI detected at non-operative hospitals are included. We utilized data from a California statewide hospital registry to assess for evidence of SSI following colon surgery or abdominal hysterectomies performed 3/1/2011-11/30/2013 using previously validated claims-based SSI surveillance methods. Risk-adjusted hospital-specific rankings based on SSI detected at operative hospitals versus any California hospital were generated. Among 60,059 colon surgeries at 285 hospitals and 64,918 abdominal hysterectomies at 270 hospitals, 5,921 (9.9%) colon surgeries and 1,481 (2.3%) abdominal hysterectomies received a diagnosis code for SSI within the 30 days following surgery. 7.2% of colon surgery and 13.4% of abdominal hysterectomy SSI would have been missed by operative hospital surveillance alone. The proportion of individual hospital's SSI detected during hospitalizations at other hospitals varied widely. Including non-operative hospital SSI resulted in improved relative ranking of 11 (3.9%) colon surgery and 13 (4.8%) hysterectomy hospitals so that they were no longer in the worst performing quartile, mainly among hospitals with relatively high surgical volumes. Standard SSI surveillance that mainly focuses on infections detected at the operative hospital causes varying degrees of SSI under-estimation, leading to inaccurate assignment or avoidance of financial penalties for approximately one in eleven to sixteen hospitals.

To estimate the association of 1 activity of the Prevention and Public Health Fund with hospital bloodstream infections and calculate the return on investment (ROI). The activity was funded for 1 year (2013). A difference-in-differences specification evaluated hospital standardized infection ratios (SIRs) before funding allocation (years 2011 and 2012) and after funding allocation (years 2013 and 2014) in the 15 US states that received the funding compared with hospital SIRs in states that did not receive the funding. We estimated the association of the funded public health activity with SIRs for bloodstream infections. We calculated the ROI by dividing cost offsets from infections averted by the amount invested. The funding was associated with a 33% (P < .05) reduction in SIRs and an ROI of $1.10 to $11.20 per $1 invested in the year of funding allocation (2013). In 2014, after the funding stopped, significant reductions were no longer evident. This activity was associated with a reduction in bloodstream infections large enough to recoup the investment. Public health funding of carefully targeted areas may improve health and reduce health care costs.

Full Text Available Aims: Nosocomial infection is associated with increased mortality, morbidity, and length of stay. Detection of infection, identify the etiology of bacterial antibiotic resistance pattern, is necessary given the widespread use of antibiotics and antibiotic-resistant organisms. Materials and Methods: This cross-sectional study was done on 288 patients admitted to the Beheshti Hospitals in Kashan based on NNIS definitions according to the state of Health and Medical education. In this study infections and antibiotic resistance symptoms were found. Data analyses were performed with Chi-square test. Results: Among the 288 patients studied, with mean out of hospital infection was 0.80%. Most cases of infection associated were pneumonia. The highest rates of infection were in the Intensive Care Unit (ICU with 51.7%. Nosocomial infection in ICU wards was associated with increased mortality and morbidity. The most common types were ventilator-associated pneumonia. Among the microorganisms, negative Gram was seen more. The common pathogens were including Acinetobacter, Escherichia coli, and Klebsiella. Antimicrobial resistance was generally increasing and had emerged from selective pressure from antibiotic use and transmission through health staff. Conclusion: This study showed a correlation between antibiotic use and resistance of microorganisms is significant. Hence, it seems that reducing aggressive acts and conduct hygiene education and monitoring act of antibiotics is necessary to prevent antibiotic resistance.

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

CDI data were collected with an electronic case report form (CRF from five Hospitals in Italy. Hospitals collected all resource use attributable to CDI during the period 2011-2014. All resource use from initial presentation to the healthcare provider for CDI symptoms, until resolution of infection attributable to CDI in each enrolled patient was included. The patient cohort was analysed both as a whole and in stratified subgroups (by age, gender and co-morbidities. The impact of CDI on hospital length of stay (LOS was used to calculate CDI-attributable costs. The total cost of a CDI episode was estimated by multiplying each resource used by its unit cost (national tariffs and market prices; finally, the mean cost/patient was calculated across the cohort.ResultsIn total, data were collected for 488 adult infected patients (mean age 76.0 years [SD ± 15.48]; female 56.6%. Five hundred and three (503 episodes were evaluated (mean number per patient: 1.03 [SD ± 0.23]. LOS attributable to CDI was 14.6 days (SD ± 13.14. Attributable cost per adult patient was €10,224.08 (SD ± €8,963.86, with the majority of the cost being due to hospitalization. The mean cost of a recurrent episode of CDI was €9,504.87 [SD ± €8,614.11].ConclusionsThese findings show that the economic burden of CDI is considerable in Italy. The most important cost driver was the LOS attributable to CDI.

Hand hygiene noncompliance is a major cause of nosocomial infection. Nosocomial infection cost data exist, but the effect of hand hygiene noncompliance is unknown. To estimate methicillin-resistant Staphylococcus aureus (MRSA)-related cost of an incident of hand hygiene noncompliance by a healthcare worker during patient care. Two models were created to simulate sequential patient contacts by a hand hygiene-noncompliant healthcare worker. Model 1 involved encounters with patients of unknown MRSA status. Model 2 involved an encounter with an MRSA-colonized patient followed by an encounter with a patient of unknown MRSA status. The probability of new MRSA infection for the second patient was calculated using published data. A simulation of 1 million noncompliant events was performed. Total costs of resulting infections were aggregated and amortized over all events. Duke University Medical Center, a 750-bed tertiary medical center in Durham, North Carolina. Model 1 was associated with 42 MRSA infections (infection rate, 0.0042%). Mean infection cost was $47,092 (95% confidence interval [CI], $26,040-$68,146); mean cost per noncompliant event was $1.98 (95% CI, $0.91-$3.04). Model 2 was associated with 980 MRSA infections (0.098%). Mean infection cost was $53,598 (95% CI, $50,098-$57,097); mean cost per noncompliant event was $52.53 (95% CI, $47.73-$57.32). A 200-bed hospital incurs $1,779,283 in annual MRSA infection-related expenses attributable to hand hygiene noncompliance. A 1.0% increase in hand hygiene compliance resulted in annual savings of $39,650 to a 200-bed hospital. Hand hygiene noncompliance is associated with significant attributable hospital costs. Minimal improvements in compliance lead to substantial savings.

To investigate the prevalence of respiratory syncytial virus (RSV) infection in hospitalized children and the relationship between the prevalence and the climate change in Suzhou, China. A total of 42 664 nasopharyngeal secretions from hospitalized children with acute respiratory infection at the Suzhou Children's Hospital were screened for RSV antigens using direct immunofluorescence. Monthly meteorological data (mean monthly air temperature, monthly relative humidity, monthly rainfall, total monthly sunshine duration, and mean monthly wind velocity) in Suzhou between 2001 and 2011 were collected. The correlations between RSV detection rate and climatic factors were evaluated using correlation and stepwise regression analysis. The annual RSV infection rate in hospitalized children with respiratory infection in the Suzhou Children's Hospital varied between 11.85% and 27.30% from 2001 to 2011. In the 9 epidemic seasons, each spanning from November to April of the next year, from 2001 to 2010, the RSV detection rates were 40.75%, 22.72%, 39.93%, 27.37%, 42.71%, 21.28%, 38.57%, 19.86%, and 29.73%, respectively; there were significant differences in the detection rate between the epidemic seasons. The monthly RSV detection rate was negatively correlated with mean monthly air temperature, total monthly sunshine duration, monthly rainfall, monthly relative humidity, and mean monthly wind velocity (P<0.05). Stepwise regression analysis showed that mean monthly air temperature fitted into a linear model (R(2)=0.64, P<0.01). From 2001 to 2011, RSV infection in Suzhou was predominantly prevalent between November and April of the next year. As a whole, the infection rate of RSV reached a peak every other year. Air temperature played an important role in the epidemics of RSV infection in Suzhou.

Introduction Our study was conducted, in university hospital center (UHC) Farhat Hached of Sousse (city in Tunisian center-east), within healthcare-associated infections (HAI) epidemiological surveillance (ES) program, based, among others, on HAI regular prevalence surveys. Our objectives are to resituate HAI prevalence rate and to identify their risk factors (RF) in order to adjust, in our hospital, prevention programs. Methods It is a transversal descriptive study, including all patients who had been hospitalized for at least 48 hours, measuring prevalence of HAI a “given day”, with only one passage by service. Risk factors were determined using Epiinfo 6.0, by uni-varied analysis, then, logistic regression stepwise descending for the variables whose p Results The study focused on 312 patients. Infected patients prevalence was 12.5% and that of HAI was 14.5%. Infections on peripheral venous catheter (PVC) dominated (42.2%) among all HAI identified. HAI significant RF were neutropenia (p < 10−4) for intrinsic factors, and PVC for extrinsic factors (p = 0,003). Conclusion Predominance of infections on PVC should be subject of specific prevention actions, including retro-information strategy, prospective ES, professional practices evaluation and finally training and increasing awareness of health personnel with hygiene measures. Finally, development of a patient safety culture with personnel ensures best adherence to hygiene measures and HAI prevention. PMID:26113928

The human microbiota: novel targets for hospital-acquired infections and antibiotic resistance.

Hospital-acquired infections are increasing in frequency due to multidrug resistant organisms (MDROs), and the spread of MDROs has eroded our ability to treat infections. Health care professionals cannot rely solely on traditional infection control measures and antimicrobial stewardship to prevent MDRO transmission. We review research on the microbiota as a target for infection control interventions. We performed a literature review of key research findings related to the microbiota as a target for infection control interventions. These data are summarized and used to outline challenges, opportunities, and unanswered questions in the field. The healthy microbiota provides protective functions including colonization resistance, which refers to the microbiota's ability to prevent colonization and/or expansion of pathogens. Antibiotic use and other exposures in hospitalized patients are associated with disruptions of the microbiota that may reduce colonization resistance and select for antibiotic resistance. Novel methods to exploit protective mechanisms provided by an intact microbiota may provide the key to preventing the spread of MDROs in the health care setting. Research on the microbiota as a target for infection control has been limited. Epidemiologic studies will facilitate progress toward the goal of manipulating the microbiota for control of MDROs in the health care setting. Copyright © 2016 Elsevier Inc. All rights reserved.

Limited data exist on clinical characteristics and outcomes of patients who had infective endocarditis after undergoing transcatheter aortic valve replacement (TAVR). To determine the associated factors, clinical characteristics, and outcomes of patients who had infective endocarditis after TAVR. The Infectious Endocarditis after TAVR International Registry included patients with definite infective endocarditis after TAVR from 47 centers from Europe, North America, and South America between June 2005 and October 2015. Transcatheter aortic valve replacement for incidence of infective endocarditis and infective endocarditis for in-hospital mortality. Infective endocarditis and in-hospital mortality after infective endocarditis. A total of 250 cases of infective endocarditis occurred in 20 006 patients after TAVR (incidence, 1.1% per person-year; 95% CI, 1.1%-1.4%; median age, 80 years; 64% men). Median time from TAVR to infective endocarditis was 5.3 months (interquartile range [IQR], 1.5-13.4 months). The characteristics associated with higher risk of progressing to infective endocarditis after TAVR was younger age (78.9 years vs 81.8 years; hazard ratio [HR], 0.97 per year; 95% CI, 0.94-0.99), male sex (62.0% vs 49.7%; HR, 1.69; 95% CI, 1.13-2.52), diabetes mellitus (41.7% vs 30.0%; HR, 1.52; 95% CI, 1.02-2.29), and moderate to severe aortic regurgitation (22.4% vs 14.7%; HR, 2.05; 95% CI, 1.28-3.28). Health care-associated infective endocarditis was present in 52.8% (95% CI, 46.6%-59.0%) of patients. Enterococci species and Staphylococcus aureus were the most frequently isolated microorganisms (24.6%; 95% CI, 19.1%-30.1% and 23.3%; 95% CI, 17.9%-28.7%, respectively). The in-hospital mortality rate was 36% (95% CI, 30.0%-41.9%; 90 deaths; 160 survivors), and surgery was performed in 14.8% (95% CI, 10.4%-19.2%) of patients during the infective endocarditis episode. In-hospital mortality was associated with a higher logistic EuroSCORE (23.1% vs 18.6%; odds ratio

To assess the prevalence and risk factors for HBV, HCV and HTLV-I co-infection in the Iranian HIV positive Injecting Drug Users (IDU) patients admitted in hospital. Analyses were based on 154 male IDU patients admitted in Infectious disease ward of Razi Hospital, Ahwaz, Iran, from April 2001 to March 2003. All of them had been tested for HIV infection (Elisa-antibody and Western blot), HBV surface antigen, HCV antibody and HTLV-1 antibody. One hundred and four patients (67.53%) were identified as HIV infected. Among HIV infected, HB surface antigen, HCV antibody and HTLV-I antibody were positive in 44.23% and 74.04% and 16.33% patients respectively. HCV/HBV/HIV and HCV/HBV/HIV/HTLV-1 co-infection were 20.20% and 8.65% respectively. Co-infection with HBV or HCV or HTLV-1 is common among hospitalized HIV-infected IDU patients in the region of study. HIV disease outcomes appear to be adversely affected by HBV/HCV/HTLV-I co-infection, so identification of these viral infections is recommended as routine tests for this population. (author)

Full Text Available Backgound and Objectives: Individuals living in cities increasingly spend more time indoors in air-conditioned environments. Air conditioner contamination can be caused by the presence of aerosols from the external or internal environment, which may be associated with disease manifestations in patients present in this type of environment. Therefore, the aim of this review was to assess the air quality in air-conditioned hospital environments as a risk factor for hospital-acquired infections – HAI – as the air can be a potential source of infection, as well as assess the exposure of professionals and patients to different pollutants. Material and Methods: A literature review was performed in the LILACS, MEDLINE, SCIELO, SCIENCE DIRECT databases, CAPES thesis database and Ministry of Health – Brazil, including studies published between 1982 and 2008. The literature search was grouped according to the thematic focus, as follows: ventilation, maintenance and cleaning of systems that comprehend the environmental quality standard. Discussion and Conclusion: Outbreaks of hospital-acquired infections associated with Aspergillus, Acinetobacter, Legionella, and other genera such as Clostridium and Nocardia, which were found in air conditioners, were observed, thus indicating the need for air-conditioning quality control in these environments.

The study was done on 250 selected patients during the year 2010 as a retrospective descriptive study. Patients were selected as purposive sample, all of them having been exposed to urinary catheterization; hospital-acquired UTI were found in 100 patients. Data were abstracted from the archived patients' files in the medical record department using the annual infection control logbook prepared by the infection control department. The data collected were demographic information about the patients, clinical condition (diagnosis and the LOS, and possible risk factors for infection such as duration of catheterization, exposure to invasive devices or surgical procedures, and medical condition.Results: There was a statistically significant association between the rate of UTI and duration of catheterization: seven patients had UTI out of 46 catheterized patients (15% at 3 days of catheterization, while 30 patients had UTI out of 44 catheterized patients (68% at 8 days of catheterization (median 8 days in infected patients versus 3 days in noninfected patients; P-value <0.05, which means that the longer the duration of catheterization, the higher the UTI rate. There was a statistically significant association between the rate of UTI and LOS

Transmission of tuberculosis (TB) to health care workers (HCWs) is a global issue. Although effective infection control measures are expected to reduce nosocomial TB, HCWs' infection has not been assessed enough in TB high burden countries. We conducted a cross-sectional study to determine the prevalence of TB infection and its risk factors among HCWs in Hanoi, Viet Nam. A total of 300 HCWs including all staff members in a municipal TB referral hospital received an interferon-gamma release assay (IGRA), QuantiFERON-TB Gold In-Tube(TM), followed by one- and two-step tuberculin skin test (TST) and a questionnaire-based interview. Agreement between the tests was evaluated by kappa statistics. Risk factors for TB infection were analyzed using a logistic regression model. Among the participants aged from 20 to 58 years (median = 40), prevalence of TB infection estimated by IGRA, one- and two-step TST was 47.3%, 61.1% and 66.3% respectively. Although the levels of overall agreement between IGRA and TST were moderate, the degree of agreement was low in the group with BCG history (kappa = 0.29). Working in TB hospital was associated with twofold increase in odds of TB infection estimated by IGRA. Increased age, low educational level and the high body mass index also demonstrated high odds ratios of IGRA positivity. Prevalence of TB infection estimated by either IGRA or TST is high among HCWs in the hospital environment for TB care in Viet Nam and an infection control program should be reinforced. In communities with heterogeneous history of BCG vaccination, IGRA seems to estimate TB infection more accurately than any other criteria using TST.

Sepsis induces inflammation in response to infection and is a major cause of mortality and hospitalization in children. Obesity induces chronic inflammation leading to many clinical manifestations. Our understanding of the impact of obesity on diseases, such as infection and sepsis, is limited. The objective of this study was to evaluate the association of obesity with organ dysfunction, mortality, duration, and charges during among US children hospitalized with infection. Retrospective study of hospitalizations in children with infection aged 0 to 20 years, using the 2009 Kids' Inpatient Database. Of 3.4 million hospitalizations, 357 701 were for infection, 5685 of which were reported as obese children. Obese patients had higher rates of organ dysfunction (7.35% vs 5.5%, P obesity status (odds ratio: 0.56, 95% confidence interval: 0.23-1.34), however severity of illness modified the association between obesity status and the other outcomes. While there was no difference in in-hospital mortality by obesity diagnosis, variation in organ dysfunction, hospital stay, and hospital charges according to obesity status was mediated by illness severity. Findings from this study have significant implications for targeted approaches to mitigate the burden of obesity on infection and sepsis.

The impact of Clostridium difficile infection (CDI) on healthcare costs is significant due to the extra costs of associated inpatient care. However, the specific contribution of recurrences has rarely been studied. The aim of this study was to estimate the hospital costs of CDI and the fraction attributable to recurrences in French acute-care hospitals. A retrospective study was performed for 2011 on a sample of 12 large acute-care hospitals. CDI costs were estimated from both hospital and public insurance perspectives. For each stay, CDI additional costs were estimated by comparison to controls without CDI extracted from the national DRG (diagnosis-related group) database and matched on DRG, age and sex. When CDI was the primary diagnosis, the full cost of stay was used. A total of 1067 bacteriological cases of CDI were identified corresponding to 979 stays involving 906 different patients. Recurrence(s) were identified in 118 (12%) of these stays with 51.7% of them having occurred within the same stay as the index episode. Their mean length of stay was 63.8 days compared to 25.1 days for stays with an index case only. The mean extra cost per stay with CDI was estimated at €9,575 (median: €7,514). The extra cost of CDI in public acute-care hospitals was extrapolated to €163.1 million at the national level, of which 12.5% was attributable to recurrences. The economic burden of CDI is substantial and directly impacts healthcare systems in France. Copyright © 2015 The Healthcare Infection Society. Published by Elsevier Ltd. All rights reserved.

To determine the prevalence and associated factors of the hospitalization of pregnant women for treatment of urinary tract infection and the repercussions on the health of the newborn, and the absence of a urine exam during the prenatal period. A cross-sectional design, where were eligible all mothers of newborns with births occurring between January 1st and December 31, 2010 in Rio Grande (RS). Mothers were interviewed in the two maternity hospitals in the city. Information was collected regarding hospitalization for urinary tract infection, the prenatal assistance and sociodemographic conditions. Statistical analyses were performed by levels and controlled for confounding using Poisson regression. Of the 2,288 women eligible for the study, 2.9% were hospitalized for treatment of urinary tract infection and was higher, after adjustment, in woman with lowest economic status (3.1% the lowest and 2.1% the highest), younger (4.0% in adolescents and 1.8% in those over 30 years), had less education (3.1% had seven years or less of studying and 1.2% had 12 years or more) and did not live with a partner (4.3% living without partner and 2.6% living with partner). Pathologies of the newborn associated with hospitalization, were preterm birth (4.1% in pre-term and 2.7% in those at term) and low birth weight (6.4% in low and 2.6% in those in normal). Of the women who underwent prenatal care, 23.6% had not done the urine test as recommended and, after adjustment, and the risk for not done the test was higher among those with lower socioeconomic status (34.4% in lower and 14.4% in the highest level), less educated (32.3% with seven years or less of studying and 11.0% with 12 years or more) and not living with a partner (32.7% living without partner and 22.0% living with partner). The high rate of hospitalization reflects the lack of effectiveness of screening for urinary tract infection during pregnancy. The socioeconomic profile of women who required hospitalization and who

Antimicrobial resistance is threatening the successful management of nosocomial infections worldwide. Despite the therapeutic limitations imposed by methicillin-resistant Staphylococcus aureus (MRSA), its clinical impact is still debated. The objective of this study was to estimate the excess mortality and length of hospital stay (LOS) associated with MRSA bloodstream infections (BSI) in European hospitals. Between July 2007 and June 2008, a multicenter, prospective, parallel matched-cohort study was carried out in 13 tertiary care hospitals in as many European countries. Cohort I consisted of patients with MRSA BSI and cohort II of patients with methicillin-susceptible S. aureus (MSSA) BSI. The patients in both cohorts were matched for LOS prior to the onset of BSI with patients free of the respective BSI. Cohort I consisted of 248 MRSA patients and 453 controls and cohort II of 618 MSSA patients and 1,170 controls. Compared to the controls, MRSA patients had higher 30-day mortality (adjusted odds ratio [aOR] = 4.4) and higher hospital mortality (adjusted hazard ratio [aHR] = 3.5). Their excess LOS was 9.2 days. MSSA patients also had higher 30-day (aOR = 2.4) and hospital (aHR = 3.1) mortality and an excess LOS of 8.6 days. When the outcomes from the two cohorts were compared, an effect attributable to methicillin resistance was found for 30-day mortality (OR = 1.8; P = 0.04), but not for hospital mortality (HR = 1.1; P = 0.63) or LOS (difference = 0.6 days; P = 0.96). Irrespective of methicillin susceptibility, S. aureus BSI has a significant impact on morbidity and mortality. In addition, MRSA BSI leads to a fatal outcome more frequently than MSSA BSI. Infection control efforts in hospitals should aim to contain infections caused by both resistant and susceptible S. aureus.

Patients admitted during a 6-month period to a maternity hospital in Saudi Arabia were studied for nosocomial infections and misuse of antibiotics. Patient history and diagnosis on admission and subsequent clinical and laboratory data were analysed. Infection developing from 72 h after admission was considered nosocomial. Therapeutic and prophylactic data as recorded on the patients' charts were assessed for possible misuse of antibiotics. Of 3439 patients, 136 (4.0%) developed nosocomial infection: 2.0%, 8.9% and 37.7% in obstetric, gynaecologic and nursery patients, respectively. Infections among adults were mostly found in the urinary (44.4%) and lower genital (33.3%) tracts. Among newborns, over 70% of cases were eye and ear (29.8%), skin (26.2%) and blood (19.0%) infections. Gram-negative bacteria caused 65.7% of the infections. Over 90% of the bacterial isolates were multidrug-resistant. About 24% of patients received single or multiple antibiotics; 57.2% were misused. The minimal hospital cost estimate for both nosocomial infections and misused antibiotics was US $318,705. The findings of this study, the first of its type in this region, should prompt improved infection control measures as well as educational and antibiotic restriction interventions.

Urinary tract infections (UTI) are one of the most common bacterial infections in children and a major cause of hospitalization. In this study we investigated the clinical characteristics, causative uropathogens; their antibiotic susceptibility and resistance patterns, treatment modalities and efficacy in children hospitalized for UTI in a tertiary care setting. Patients hospitalized for an upper UTI between March 2009 and July 2014 were enrolled. The urine culture-antibiogram results and accompanying urinary tract abnormalities were recorded retrospectively. A total of 142 patients (104 girls, 73.2%; 38 boys, 26.8%) were enrolled. Mean patient age was 32.6 ± 4.1 months. History of recurrent UTI was present in 45.8% (n = 65), with prior hospitalization in 12.0% (n = 17). Frequency of vesicoureteral reflux was 18.3% (n = 26). Gram-negative enteric microorganisms yielded growth in all culture-positive UTI and the most common microorganism was Escherichia coli (n = 114, 80.3%). Extended spectrum beta-lactamase-producing (ESBL (+)) bacterial strains were detected in 49.3% (n = 70), with third-generation cephalosporin resistance in all and increased duration of hospitalization. The prevalence of UTI with ESBL (+) bacterial strains with multi-drug resistance is increasing in the hospitalized pediatric population, therefore rational use of antibiotics is essential. © 2015 Japan Pediatric Society.

Full Text Available Human metapneumovirus (HMPV has an important etiological role in acute lower respiratory infections in children under five years. Our objectives were to estimate the relative contribution of HMPV to hospitalization in children with acute respiratory infection, to define the clinical and epidemiological features of HMPV single and multiple infections, and to compare HMPV infections with respiratory syncytial virus (HRSV, rhinovirus (HRV, adenovirus and human bocavirus infections in the same population.A prospective study performed on all children less than 14 years of age with a respiratory tract disease admitted to a secondary hospital between September 2005- June 2014. Clinical characteristics of patients were analyzed. Nasopharyngeal aspirate was taken at admission for viral study with polymerase chain reaction for 16 respiratory viruses. A total of 3,906 children were included. At least one respiratory virus was detected in 75.2% of them. The most common identified virus was HRSV, followed by HRV. HMPV was detected in 214 cases (5.5%; 133 (62% were single infections and the remaining were detected in coinfection with other viruses. 90.7% cases were detected between February and May. Children's mean age was 13.83 ± 18 months. Fever was frequent (69%, and bronchiolitis (27%, and recurrent wheezing (63% were the main clinical diagnosis. Hypoxia was present in 65% of the patients and 47% of them had an infiltrate in X-ray. Only 6 (2.8% children were admitted to the intensive care unit. Only the duration of the hospitalization was different, being longer in the coinfections group (p <0.05. There were many differences in seasonality and clinical characteristics between HMPV and other respiratory viruses being more similar to HRSV.HMPV infections accounted for 5.5% of total viral infections in hospitalized children. The clinical characteristics were similar to HRSV infections, but seasonality and clinical data were different from other viral

Methods for identifying surgical wound infection after discharge from hospital: a systematic review

Full Text Available Abstract Background Wound infections are a common complication of surgery that add significantly to the morbidity of patients and costs of treatment. The global trend towards reducing length of hospital stay post-surgery and the increase in day case surgery means that surgical site infections (SSI will increasingly occur after hospital discharge. Surveillance of SSIs is important because rates of SSI are viewed as a measure of hospital performance, however accurate detection of SSIs post-hospital discharge is not straightforward. Methods We conducted a systematic review of methods of post discharge surveillance for surgical wound infection and undertook a national audit of methods of post-discharge surveillance for surgical site infection currently used within United Kingdom NHS Trusts. Results Seven reports of six comparative studies which examined the validity of post-discharge surveillance methods were located; these involved different comparisons and some had methodological limitations, making it difficult to identify an optimal method. Several studies evaluated automated screening of electronic records and found this to be a useful strategy for the identification of SSIs that occurred post discharge. The audit identified a wide range of relevant post-discharge surveillance programmes in England, Scotland and Wales and Northern Ireland; however, these programmes used varying approaches for which there is little supporting evidence of validity and/or reliability. Conclusion In order to establish robust methods of surveillance for those surgical site infections that occur post discharge, there is a need to develop a method of case ascertainment that is valid and reliable post discharge. Existing research has not identified a valid and reliable method. A standardised definition of wound infection (e.g. that of the Centres for Disease Control should be used as a basis for developing a feasible, valid and reliable approach to defining post

The CDI definition was based on the current recommendations of the European Society of Clinical Microbiology and Infectious Diseases.Results: The observation period was divided into two 13-month intervals. Increased incidence (of borderline significance of CDI in the second period compared to the first period was observed (1.33% vs 0.65% respectively; p=0.057. Patients after kidney (n=11, kidney and pancreas (n=2 and liver (n=5 transplantation represented 48% of the analyzed CDI patients, and in half of these patients (50% CDI symptoms occurred within the first 3 months after transplantation. Clostridium difficile infection leads to irreversible deterioration of graft function in 38% of kidney recipients. Most incidents of CDI (70% were identified as nosocomial infection.Conclusions: 1. Clostridium difficile infection is particularly common among patients in the early period after solid organ transplantation. 2. Clostridium difficile infection may lead to irreversible deterioration of transplanted kidney function.

Introduction. Blood stream infection (BSI) is a common problem of newborn in neonatal intensive care units (NICUs). Monitoring neonatal infections is increasingly regarded as an important contributor to safe and high-quality healthcare. It results in high mortality rate and serious complications. So, our aim was to determine the incidence and the pattern of BSIs in the NICU of Suez Canal University Hospital, Egypt, and to determine its impact on hospitalization, mortality, and morbidity. Methods. This study was a prospective one in which all neonates admitted to the NICUs in Suez Canal University hospital between January, 2013 and June 2013 were enrolled. Blood stream infections were monitored prospectively. The health care associated infection rate, mortality rate, causative organism, and risk factors were studied. Results. A total of 317 neonates were admitted to the NICU with a mortality rate of 36.0%. During this study period, 115/317 (36.3%) developed clinical signs of sepsis and were confirmed as BSIs by blood culture in only 90 neonates with 97 isolates. The total mean length of stay was significantly longer among infected than noninfected neonates (34.5 ± 18.3 and 10.8 ± 9.9 days, resp., P value Suez Canal University Hospital was relatively high with high mortality rate (36.0%).

Full Text Available BACKGROUND: Transmission of tuberculosis (TB to health care workers (HCWs is a global issue. Although effective infection control measures are expected to reduce nosocomial TB, HCWs' infection has not been assessed enough in TB high burden countries. We conducted a cross-sectional study to determine the prevalence of TB infection and its risk factors among HCWs in Hanoi, Viet Nam. METHODOLOGY/PRINCIPAL FINDINGS: A total of 300 HCWs including all staff members in a municipal TB referral hospital received an interferon-gamma release assay (IGRA, QuantiFERON-TB Gold In-Tube(TM, followed by one- and two-step tuberculin skin test (TST and a questionnaire-based interview. Agreement between the tests was evaluated by kappa statistics. Risk factors for TB infection were analyzed using a logistic regression model. Among the participants aged from 20 to 58 years (median = 40, prevalence of TB infection estimated by IGRA, one- and two-step TST was 47.3%, 61.1% and 66.3% respectively. Although the levels of overall agreement between IGRA and TST were moderate, the degree of agreement was low in the group with BCG history (kappa = 0.29. Working in TB hospital was associated with twofold increase in odds of TB infection estimated by IGRA. Increased age, low educational level and the high body mass index also demonstrated high odds ratios of IGRA positivity. CONCLUSIONS/SIGNIFICANCE: Prevalence of TB infection estimated by either IGRA or TST is high among HCWs in the hospital environment for TB care in Viet Nam and an infection control program should be reinforced. In communities with heterogeneous history of BCG vaccination, IGRA seems to estimate TB infection more accurately than any other criteria using TST.

Staphylococcal cassette chromosome mec typing, multilocus sequence typing, accessory gene regulator typing, staphylococcal protein A typing, and pulsed field gel electrophoresis were used, along with determination of the presence of Panton–Valentine leucocidin toxin and endotoxin gene cluster among each sequence type.Results: The majority of eye infections, both severe and nonsevere, were caused by sequence type (ST772, positive for the Panton–Valentine leucocidin gene, and carrying methicillin-resistant staphylococcal cassette chromosome mec type V cassette (22/33, 67%. Some of the other sequence types that caused severe eye infections were ST1 (9%, 5 (3%, 72 (6%, 88 (3%, 121 (3%, and 672 (3%. This is the first report of the presence of ST1 and 88 in India.Conclusion: Although the number of isolates included in this study was small, most of the eye infections were caused by community-associated S. aureus where patients had no history of hospitalization or treatment in the past year. In the case of six severe infections, patients were admitted for surgeries and there is probability of hospital infection. In addition, only methicillin-resistant S. aureus isolates carrying staphylococcal cassette chromosome mec type V were

The incidence, severity, and associated costs of Clostridium difficile (C. difficile) infection (CDI) have dramatically increased in hospitals over the past decade, indicating an urgent need for strategies to prevent transmission of C. difficile. This article describes a multifaceted collaborative approach to reduce hospital-onset CDI rates in 35 acute care hospitals in the New York metropolitan region. Hospitals participated in a comprehensive CDI reduction intervention and formed interdisciplinary teams to coordinate their efforts. Standardized clinical infection prevention and environmental cleaning protocols were implemented and monitored using checklists. Monthly data reports were provided to hospitals for facility-specific performance evaluation and comparison to aggregate data from all participants. Hospitals also participated in monthly teleconferences to review data and highlight successes, challenges, and strategies to reduce CDI. Incidence of hospital-onset CDI per 10,000 patient days was the primary outcome measure. Additionally, the incidence of nonhospital-associated, community-onset, hospital-associated, and recurrent CDIs were measured. The use of a collaborative model to implement a multifaceted infection prevention strategy was temporally associated with a significant reduction in hospital-onset CDI rates in participating New York metropolitan regional hospitals. © 2013 National Association for Healthcare Quality.

Hand washing is widely accepted as the cornerstone of infection control in the intensive care unit (ICU). Nosocomial infections are frequently viewed as indicating poor compliance with hand washing guidelines. To determine the hand hygiene (HH) compliance rate among healthcare workers (HCWs) and its effect on the nosocomial infection rates in the ICU of our hospital, we conducted an interventional study. The study spanned a period of 7 months (February 2011-August 2011) and consisted of education about HH indications and techniques, workplace reminder posters, focused group sessions, and feedback on the HH compliance and infection rates. The WHO HH observation protocol was used both before and after a hospital-wide HH campaign directed at all staff members, particularly those in the ICU. Compliance was measured by direct observation of the HCWs, using observation record forms in a patient-directed manner, with no more than two patients observed simultaneously. The overall HH compliance rate was calculated by dividing the number of HH actions by the total number of HH opportunities. The nosocomial infection rates for the pre- and post-interventional periods were also compared to establish the effect of the intervention on rate of infections acquired within the unit. The overall rate of HH compliance by all the HCWs increased from 42.9% pre-intervention to 61.4% post-intervention, P<0.001. Individually, the compliance was highest among the nurses, 49.9 vs. 82.5%, respectively (P<0.001) and lowest among the doctors, 38.6 vs. 43.2%, respectively (P=0.24). The effect of the increase in the HH compliance rate on the nosocomial infection rate was remarkable. There were significant reductions in the following: the rate of overall health care-associated infections/1000 patient-days, which fell from 37.2 pre-intervention to 15.1 post-intervention (P<0.001); the rate of bloodstream infections, which fell from 18.6 to 3.4/1000 central-line-days (P<0.001); and the rate of lower

This report provides a national cross-sectional snapshot of infection prevention and control programs and clinician compliance with the implementation of processes to prevent health care-associated infections (HAIs) in intensive care units (ICUs). All hospitals, except Veterans Affairs hospitals, enrolled in the National Healthcare Safety Network (NHSN) were eligible to participate. Participation involved completing a survey assessing the presence of evidence-based prevention policies and clinician adherence and joining our NHSN research group. Descriptive statistics were computed. Facility characteristics and HAI rates by ICU type were compared between respondents and nonrespondents. Of the 3,374 eligible hospitals, 975 provided data (29% response rate) on 1,653 ICUs, and there were complete data on the presence of policies in 1,534 ICUs. The average number of infection preventionists (IPs) per 100 beds was 1.2. Certification of IP staff varied across institutions, and the average hours per week devoted to data management and secretarial support were generally low. There was variation in the presence of policies and clinician adherence to these policies. There were no differences in HAI rates between respondents and nonrespondents. Guidelines for IP staffing in acute care hospitals need to be updated. In future work, we will analyze the associations between HAI rates and infection prevention and control program characteristics, as well as the inplementation of and clinician adherence to evidence-based policies.

Full Text Available Abstract Background Healthcare associated infections (HAI are the most common preventable adverse events following admission to healthcare facilities. Data from low-income countries are scarce. We sought to prospectively define HAI incidence at Angkor Hospital for Children (AHC, a Cambodian pediatric referral hospital. Methods Prospective HAI surveillance was introduced for medical admissions to AHC. Cases were identified on daily ward rounds and confirmed using locally adapted Centers for Disease Control and Prevention (CDC definitions. During the surveillance period, established infection prevention and control (IPC activities continued, including hand hygiene surveillance. In addition, antimicrobial stewardship practices such as the creation of an antimicrobial guideline smartphone app were introduced. Results Between 1st January and 31st December 2015 there were 3,263 medical admissions and 102 HAI cases. The incidence of HAI was 4.6/1,000 patient-days (95% confidence interval 3.8–5.6 and rates were highest amongst neonates. Median length of stay was significantly longer in HAI cases: 25 days versus 5 days for non-HAI cases (p < 0.0001. All-cause in-hospital mortality increased from 2.0 to 16.1% with HAI (p < 0.0001. Respiratory infections were the most common HAI (54/102; 52.9%. Amongst culture positive infections, Gram-negative organisms predominated (13/16; 81.3%. Resistance to third generation cephalosporins was common, supporting the use of more expensive carbapenem drugs empirically in HAI cases. The total cost of treatment for all 102 HCAI cases combined, based on additional inpatient days, was estimated to be $299,608. Conclusions Prospective HAI surveillance can form part of routine practice in low-income healthcare settings. HAI incidence at AHC was relatively low, but human and financial costs remained high due to increased carbapenem use, prolonged admissions and higher mortality rates.

Human parainfluenza viruses account for a significant proportion of lower respiratory tract infections in children. To assess the prevalence of Human parainfluenza viruses as a cause of acute respiratory infection and to compare clinical data for this infection against those of the human respiratory syncytial virus. A prospective study in children younger than five years with acute respiratory infection was conducted. Detection of respiratory viruses in nasopharyngeal aspirate samples was performed using the indirect immunofluorescence reaction. Length of hospital stay, age, clinical history and physical exam, clinical diagnoses, and evolution (admission to Intensive Care Unit or general ward, discharge or death) were assessed. Past personal (premature birth and cardiopathy) as well as family (smoking and atopy) medical factors were also assessed. A total of 585 patients were included with a median age of 7.9 months and median hospital stay of six days. No difference between the HRSV+ and HPIV+ groups was found in terms of age, gender or length of hospital stay. The HRSV+ group had more fever and cough. Need for admission to the Intensive Care Unit was similar for both groups but more deaths were recorded in the HPIV+ group. The occurrence of parainfluenza peaked during the autumn in the first two years of the study. Parainfluenza was responsible for significant morbidity, proving to be the second-most prevalent viral agent in this population after respiratory syncytial virus. No difference in clinical presentation was found between the two groups, but mortality was higher in the HPIV+ group. Copyright © 2015. Published by Elsevier Editora Ltda.

From January to May 2012, 1,860 hospitals throughout Germany received a questionnaire encompassing 77 items. Additionally, 300 outpatient care services and 310 nursing homes for elderly in Berlin also received a 10-item questionnaire asking on their implemented infection control practices. All questionnaires were anonymous. A total of 229 completed questionnaires from hospitals, 14 questionnaires from outpatient care services, and 16 questionnaires from nursing homes were eligible for further analysis. The lack of Infection Control physicians was identified as the largest issue. In hospitals sized 400-999 beds a gap of 71%, and in hospitals sized ≥1,000 beds a gap of 17% was reported. Depending on the number of hospital beds, 13-29% of hospitals sized ≥100 beds reported not havening one infection control nurse. Since based on the number of beds in larger institutions or in facilities caring for high-risk patients several infection control nurses may be required, the deficiency in infection control nurses may even be higher, particularly in secondary and tertiary care facilities. Furthermore, the analysis revealed that the legal requirements for surveillance and reporting of notifiable infectious diseases have not yet been implemented in 11% of the facilities. The implementation of antibiotic strategies did show significant gaps. However, deficiencies in the implemented measures for the prevention of surgical site infections were less frequent. Yet 12% of the participants did not have a dedicated infection control concept for their surgical services. Eight percent of hospitals were not prepared for an outbreak management and 10% did not have established regulations for wearing surgical scrubs. Deficiencies in waste disposal and the control of air-conditioning systems were also noted. Based on the results of this survey, conclusions on the optimal resource allocation for further improvement of patient safety may be drawn. While all participating nursing homes had

Full Text Available Puerperal sepsis causes 10% of maternal deaths in Africa, but prospective studies on incidence, microbiology and antimicrobial resistance are lacking.We performed a prospective cohort study of 4,231 Ugandan women presenting to a regional referral hospital for delivery or postpartum care, measured vital signs after delivery, performed structured physical exam, symptom questionnaire, and microbiologic evaluation of febrile and hypothermic women. Malaria rapid diagnostic testing, blood and urine cultures were performed aseptically and processed at Epicentre Mbarara Research Centre. Antimicrobial susceptibility and breakpoints were determined using disk diffusion per EUCAST standards. Hospital diagnoses, treatments and outcomes were abstracted from patient charts.Mean age was 25 years, 12% were HIV-infected, and 50% had cesarean deliveries. Approximately 5% (205/4176 with ≥1 temperature measurement recorded developed postpartum fever or hypothermia; blood and urine samples were collected from 174 (85%, and 17 others were evaluated clinically. Eighty-four (48% had at least one confirmed source of infection: 39% (76/193 clinical postpartum endometritis, 14% (25/174 urinary tract infection (UTI, 3% (5/174 bloodstream infection. Another 3% (5/174 had malaria. Overall, 30/174 (17% had positive blood or urine cultures, and Acinetobacter species were the most common bacteria isolated. Of 25 Gram-negatives isolated, 20 (80% were multidrug-resistant and cefepime non-susceptible.For women in rural Uganda with postpartum fever, we found a high rate of antibiotic resistance among cultured urinary and bloodstream infections, including cephalosporin-resistant Acinetobacter species. Increasing availability of microbiology testing to inform appropriate antibiotic use, development of antimicrobial stewardship programs, and strengthening infection control practices should be high priorities.

Cryptococcal meningitis (CM) is a common central nervous system infection in HIV-infected patients. This study aimed to determine treatment outcomes among HIV-infected patients who had cryptococcal meningitis and to determine predictors of death. We conducted a retrospective cohort study among HIV-infected patients receiving care at Chiang Mai University Hospital from January 1, 2005 to December 31, 2010. We studied 79 patients; 45 (57.0%) were male and the mean age was 35.1 +/- 7.2 years. Eleven patients (13.9%) had previous opportunistic infection. The most common presenting symptoms were headache (63 patients, 79.8%), fever (49 patients, 62.0%), and altered consciousness (21 patients, 26.6%). The median CD4+ cell count was 20 cells/mm3 [Interquartile range (IQR) 10, 53]. The in-hospital, 90-day, and 1-year mortality rates were 24.1%, 32.4%, and 52.2%, respectively. The CM attributable in-hospital, 90-day and 1-year mortality rates were 13.9%, 20.3%, and 23.2%, respectively. Predictors associated with a 1-year mortality were a high cerebrospinal (CSF) cryptococcal antigen titer (> 1:10,000) [Odds Ratio (OR) =7.08, 95% confidence interval (CI): 1.62-31.00, p = 0.009], and altered consciousness at presentation (OR = 5.27; 95% CI: 1.16-24.05; p = 0.032). Cryptococcal meningitis is an important cause of death in HIV-infected patients. HIV-infected patients with a low CD4+ cell count, a headache, fever and altered consciousness should be investigated for CM and those with a high CSF cryptococcal antigen titer are at high risk for mortality.

Appropriate antibiotic use improves patient outcome and prevents the emergence of antibiotic resistance. A point-prevalence audit of antibiotic use at Beaumont Hospital, Dublin was carried out during the collection of data for the 2006 Hospital Infection Society (HIS) Prevalence Survey of Healthcare-Associated Infection. All inpatients who met the HIS survey entry criteria were included in the HIS survey, and all inpatients who were receiving antibiotics at the time of the survey were included in the point-prevalence audit of antibiotic use. Among these, 7.18% and 36.8% of patients had a healthcare-associated infection (HCAI) and were on antibiotics, respectively. Unnecessary collection of duplicate data was avoided by conducting an audit of antibiotic use and a national survey of HCAI simultaneously.

. Judicious use should be considered when using doripenem as a first-line agent or drug of choice for serious infections. Doripenem is a well-tolerated drug with common adverse effects including headache, nausea and diarrhea. Caution should be used in patients with hypersensitivity to carbapenems and adverse reactions to β-lactam agents. Dosage adjustment is needed for patients with renal impairment. Doripenem has demonstrated economic and clinical benefits. It has been shown to reduce hospital length of stay and duration of mechanical ventilation for intensive care unit (ICU patients. Therefore, doripenem is a welcome addition to our limited armamentarium of antibiotics available to treat serious bacterial infections in hospitalized patients.Keywords: doripenem, nosocomial pneumonia, intra-abdominal infections, urinary tract infections

To examine the outcome of surgery for active infective endocarditis (IE) in a cohort of patients. One hundred sixty-four consecutive patients who underwent valve surgery for active IE (diagnosis according to Duke criteria) in Madani Heart Center, Tabriz, Iran from 1996 to 2006 were studied. The mean age of patients was 36.3+-16 years overall: 34.6+-17.5 years for native valve endocarditis and 38.6+-15.2 yrs for prosthetic valve endocarditis (p=0.169). Ninety one (55.5%) patients were men. The infected valve was native in 112 (68.7%) of patients and prosthetic in 52(31.3%). In 61 (37%) patients, no predisposing heart disease was found. The aortic valve was infected in 78 (47.6%), mitral valve in 69 (42.1%), and multiple valves in 17 (10.3%) of patients. Active culture positive endocarditis was present in 81 (49.4%) whereas 83 (50.6%) patients had culture-negative endocarditis. Staphylococcus aureus was the most common isolated microorganism. Ninety patients (54.8%) were in NYHA classes III and IV. Mechanical valves were implanted in 69 patients (42.1%) and bioprostheses in 95 (57.9%), including a homograft in 19 (11.5%). There were 16 (9%) operative deaths, but there was only 1 death in patients that underwent aortic homograft replacement. Reoperation was required in 18 (10.9%) of cases. On multivariate logistic regression analysis, Staphylococcus aureus infection (p=0.008), prosthetic valve endocarditis (p=0.01), paravalvular abscess (p=0.001) and left ventricular ejection fraction less than 40% (p=0.04) were independent predictors of in-hospital mortality. Surgery for infective endocarditis continues to be challenging and associated with high operative mortality and morbidity. Prosthetic valve endocarditis, impaired ventricular function, paravalvular abscess and Staphylococcus aureus infection adversely affect in-hospital mortality. Also we found that aortic valve replacement with an aortic homograft can be performed with acceptable in hospital mortality and

This qualitative work was developed according to Bardin's method of content analysis. It aimed at finding out the perceptions of nurses that are members of a Hospital Infection Control Commission about ethical issues that are inherent to their professional practice as well as understanding the clinical nurses opinion regarding the professional practice of the nurses that are members of the Hospital Infection Control Commission, considering the ethical aspects. In order to achieve an ethical, efficient and effective professional practice, there is a need for governmental changes and professional recognition through autonomy, respect and exclusivity in the Service of Hospital Infection Control, as well as improvements regarding information, the care provided to the patient and professional secret. The predominance of bureaucratic activities and team work were mentioned by the clinical nurses as differentiating factors of the activities performed by nurses that are members of the Commission.

A multidisciplinary intervention to reduce infections of ESBL- and AmpC-producing, gram-negative bacteria at a University Hospital.

Jenny Dahl Knudsen

Full Text Available In response to a considerable increase in the infections caused by ESBL/AmpC-producing Klebsiella pneumonia in 2008, a multidisciplinary intervention, with a main focus on antimicrobial stewardship, was carried out at one university hospital. Four other hospitals were used as controls. Stringent guidelines for antimicrobial treatment and prophylaxis were disseminated throughout the intervention hospital; cephalosporins were restricted for prophylaxis use only, fluoroquinolones for empiric use in septic shock only, and carbapenems were selected for penicillin-allergic patients, infections due to ESBL/AmpC-producing and other resistant bacteria, in addition to their use in severe sepsis/septic shock. Piperacillin-tazobactam ± gentamicin was recommended for empiric treatments of most febrile conditions. The intervention also included education and guidance on infection control, as well as various other surveillances. Two year follow-up data on the incidence rates of patients with selected bacterial infections, outcomes, and antibiotic consumption were assessed, employing before-and-after analysis and segmented regression analysis of interrupted time series, using the other hospitals as controls. The intervention led to a sustained change in antimicrobial consumption, and the incidence of patients infected with ESBL-producing K. pneumoniae decreased significantly (p<0.001. The incidences of other hospital-associated infections also declined (p's<0.02, but piperacillin-tazobactam-resistant Pseudomonas aeruginosa and Enterococcus faecium infections increased (p's<0.033. In wards with high antimicrobial consumption, the patient gut carrier rate of ESBL-producing bacteria significantly decreased (p = 0.023. The unadjusted, all-cause 30-day mortality rates of K. pneumoniae and E. coli were unchanged over the four-year period, with similar results in all five hospitals. Although not statistically significant, the 30-day mortality rate of patients

Full Text Available The aim of this research was to investigate the prognostic and diagnostic value of some clinical and biological factors in the development of acute intestinal rotavirus infection in children. We observed 161 children aged 1 month to 6 years. 81 children were diagnosed with rotavirus infection, and 80 — with secretory diarrhea of unknown origin. Treatment of children was carried out in a hospital. Analysis of clinical and anamnestic data enabled to choose the most prognostically and diagnostically important predictors out of 117 studied risk factors. The authors investigated the association of clinical and biological factors with the severity of rotavirus infection, which would highlight the groups of children with high risk of rotavirus infection, which requires treatment in a hospital. The practical application of the results of this work should be the optimization of early diagnostics of rotavirus infections and timeliness of preventive measures.

Quantitative assessment of organizational culture within hospitals and its relevance to infection prevention and control strategies.

It has been suggested that organizational culture (OC) is an important driver of infection prevention and control (IPC) behaviour among healthcare workers. This study examined OC in seven European hospitals using a validated assessment tool based on Hofstede's model, and identified significant variations in OC scores. Hospitals with low prevalence of meticillin-resistant Staphylococcus aureus (MRSA) exhibited high scores for change facilitation and change readiness, whereas hospitals with high prevalence of MRSA exhibited low scores for these determinants. It is possible to use tools, available outside health care, to study OC within hospitals and gain better insight into IPC behaviour change strategies.

Full Text Available BACKGROUND: Acute lower respiratory infections (ALRIs are an important cause of acute illnesses and mortality worldwide and in China. However, a large-scale study on the prevalence of viral infections across multiple provinces and seasons has not been previously reported from China. Here, we aimed to identify the viral etiologies associated with ALRIs from 22 Chinese provinces. METHODS AND FINDINGS: Active surveillance for hospitalized ALRI patients in 108 sentinel hospitals in 24 provinces of China was conducted from January 2009-September 2013. We enrolled hospitalized all-age patients with ALRI, and collected respiratory specimens, blood or serum collected for diagnostic testing for respiratory syncytial virus (RSV, human influenza virus, adenoviruses (ADV, human parainfluenza virus (PIV, human metapneumovirus (hMPV, human coronavirus (hCoV and human bocavirus (hBoV. We included 28,369 ALRI patients from 81 (of the 108 sentinel hospitals in 22 (of the 24 provinces, and 10,387 (36.6% were positive for at least one etiology. The most frequently detected virus was RSV (9.9%, followed by influenza (6.6%, PIV (4.8%, ADV (3.4%, hBoV (1.9, hMPV (1.5% and hCoV (1.4%. Co-detections were found in 7.2% of patients. RSV was the most common etiology (17.0% in young children aged <2 years. Influenza viruses were the main cause of the ALRIs in adults and elderly. PIV, hBoV, hMPV and ADV infections were more frequent in children, while hCoV infection was distributed evenly in all-age. There were clear seasonal peaks for RSV, influenza, PIV, hBoV and hMPV infections. CONCLUSIONS: Our findings could serve as robust evidence for public health authorities in drawing up further plans to prevent and control ALRIs associated with viral pathogens. RSV is common in young children and prevention measures could have large public health impact. Influenza was most common in adults and influenza vaccination should be implemented on a wider scale in China.

Full Text Available Introduction. Blood stream infection (BSI is a common problem of newborn in neonatal intensive care units (NICUs. Monitoring neonatal infections is increasingly regarded as an important contributor to safe and high-quality healthcare. It results in high mortality rate and serious complications. So, our aim was to determine the incidence and the pattern of BSIs in the NICU of Suez Canal University Hospital, Egypt, and to determine its impact on hospitalization, mortality, and morbidity. Methods. This study was a prospective one in which all neonates admitted to the NICUs in Suez Canal University hospital between January, 2013 and June 2013 were enrolled. Blood stream infections were monitored prospectively. The health care associated infection rate, mortality rate, causative organism, and risk factors were studied. Results. A total of 317 neonates were admitted to the NICU with a mortality rate of 36.0%. During this study period, 115/317 (36.3% developed clinical signs of sepsis and were confirmed as BSIs by blood culture in only 90 neonates with 97 isolates. The total mean length of stay was significantly longer among infected than noninfected neonates (34.5 ± 18.3 and 10.8 ± 9.9 days, resp., P value < 0.001. The overall mortality rates among infected and noninfected neonates were 38.9% and 34.8%, respectively, with a significant difference. Klebsiella spp. were the most common pathogen (27.8% followed by Pseudomonas (21.6% and Staphylococcus aureus (15.4%. Conclusion. The rate of BSIs in NICU at Suez Canal University Hospital was relatively high with high mortality rate (36.0%.

Sharps disposal containers are ubiquitous in health care facilities; however, there is paucity of data on their potential role in pathogen transmission. This study assessed the relationship between use of single-use versus reusable sharps containers and rates of Clostridium difficile infections in a national sample of hospitals. A 2013 survey of 1,990 hospitals collected data on the use of sharps containers. Responses were linked to the 2012 Medicare Provider Analysis and Review dataset. Bivariate and multivariable negative binomial regression were conducted to examine differences in C difficile rates between hospitals using single-use versus reusable containers. There were 604 hospitals who completed the survey; of these, 539 provided data on use of sharps containers in 2012 (27% response rate). Hospitals had, on average, 289 beds (SD ± 203) and were predominantly non-for-profit (67%) and nonteaching (63%). Most used reusable sharps containers (72%). In bivariate regression, hospitals using single-use containers had significantly lower rates of C difficile versus hospitals using reusable containers (incidence rate ratio [IRR] = 0.846, P = .001). This relationship persisted in multivariable regression (IRR = 0.870, P = .003) after controlling for other hospital characteristics. This is the first study to show a link between use of single-use sharps containers and lower C difficile rates. Future research should investigate the potential for environmental contamination of reusable containers and the role they may play in pathogen transmission.

Latin America is a large and diverse region, comprising more than 600 million inhabitants and one million physicians in over 20 countries. Resistance to antibacterial drugs is particularly important in the region. This paper describes the design, implementation and results of an international bi-lingual (Spanish and Portuguese) online continuing interprofessional interactive educational program on hospital-acquired infections and antimicrobial resistance for Latin America, supported by the American Society for Microbiology. Participation, satisfaction and knowledge gain (through pre and post tests) were used. Moreover, commitment to change statements were requested from participants at the end of the course and three months later. There were 1169 participants from 19 Latin American countries who registered: 57% were physicians and 43% were other health care professionals. Of those, 1126 participated in the course, 46% received a certificate of completion and 54% a certificate of participation. There was a significant increase in knowledge between before and after the course. Of 535 participants who took both tests, the grade increased from 59 to 81%. Commitments to change were aligned with course objectives. Implementation of this educational program showed the feasibility of a continent-wide interprofessional massive course on hospital acquired-infections in Latin America, in the two main languages spoken in the region. Next steps included a new edition of this course and a "New Challenges" course on hospital-acquired infections, which were successfully implemented in the second semester of 2015 by the same institutions.

Clostridium difficile is the principal cause of infectious diarrhea in hospitalized patients. The aim of this study was to describe and compare length of stay (LOS), costs, and in-hospital deaths for C difficile infection (CDI) and non-CDI hospitalizations, in a cohort of middle-aged and older Australians. We used survey data from the 45 and Up Study, linked to hospitalization and death data. We calculated the average LOS and costs per hospitalization, and the proportion of in-hospital deaths for CDI and non-CDI hospitalizations. We then compared hospitalizations with CDI as a secondary diagnosis to non-CDI hospitalizations by stratifying hospitalizations based on principal diagnosis and then using generalized linear models to compare LOS and in-hospital costs, and logistic regression for in-hospital deaths, adjusting for age and sex. There were 641 CDI hospitalizations during 2006-2012. The average LOS was 17 days; the average cost per hospitalization was AUD 12,704; and in 7.3% of admissions (47 out of 641) the patient died. After adjusting for age and sex, hospitalizations with CDI were associated with longer LOS, higher costs, and a greater proportion of in-hospital deaths compared with hospitalizations with similar principal diagnosis but without CDI. CDI places additional burden on the Australian hospital system, with CDI patients having relatively lengthy hospital stays and high costs.

The Commission for Hospital Hygiene and Infection Prevention (KRINKO) updated the recommendations for the prevention of catheter-associated urinary tract infections in 2015. This article will describe the implementation of these recommendations in Frankfurt's hospitals in autumn, 2015. In two non-ICU wards of each of Frankfurt's 17 hospitals, inspections were performed using a checklist based on the new KRINKO recommendations. In one large hospital, a total of 5 wards were inspected. The inspections covered the structure and process quality (operating instructions, training, indication, the placement and maintenance of catheters) and the demonstration of the preparation for insertion of a catheter using an empty bed and an imaginary patient, or insertion in a model. Operating instructions were available in all hospital wards; approximately half of the wards regularly performed training sessions. The indications were largely in line with the recommendations of the KRINKO. Alternatives to urinary tract catheters were available and were used more often than the urinary tract catheters themselves (15.9% vs. 13.5%). In accordance with the recommendations, catheters were placed without antibiotic prophylaxis or the instillation of antiseptic or antimicrobial substances or catheter flushing solutions. The demonstration of catheter placement was conscientiously performed. Need for improvement was seen in the daily documentation and the regular verification of continuing indication for a urinary catheter, as well as the omission of regular catheter change. Overall, the recommendations of the KRINKO on the prevention of catheter-associated urinary tract infections were adequately implemented. However, it cannot be ruled out that in situations with time pressure and staff shortage, the handling of urinary tract catheters may be of lower quality than that observed during the inspections, when catheter insertion was done by two nurses. Against this background, a sufficient

This study estimates annual HAI hospital costs in the US avoided through use of health care antiseptics (health care personnel hand washes and rubs; surgical hand scrubs and rubs; patient preoperative and preinjection skin preparations. Methods: A spreadsheet model was developed with base case inputs derived from the published literature, supplemented with assumptions when data were insufficient. Five HAIs of interest were identified: catheter-associated urinary tract infections, central line-associated bloodstream infections, gastrointestinal infections caused by Clostridium difficile, hospital- or ventilator-associated pneumonia, and surgical site infections. A national estimate of the annual potential lost benefits from elimination of these products is calculated based on the number of HAIs, the proportion of HAIs that are preventable, the proportion of preventable HAIs associated with health care antiseptics, and HAI hospital costs. The model is designed to be user friendly and to allow assumptions about prevention across all infections to vary or stay the same. Sensitivity analyses provide low- and high-end estimates of costs avoided. Results: Low- and high-end estimates of national, annual HAIs in hospitals avoided through use of health care antiseptics are 12,100 and 223,000, respectively, with associated hospital costs avoided of US$142 million and US$4.25 billion, respectively. Conclusion: The model presents a novel

To determine the pattern of nosocomial infections in two ICUs' of a teaching hospital in terms of frequency, common sites of infection, the pathogens involved and the antibiotic sensitivity patterns. It was conducted in two medical ICUs (Neurology and Nephrology) of a public tertiary care hospital. Data was collected prospectively on patients suspected to have developed nosocomial infection after 48 hours of admission to the ICU according to objective. There were 101 cases of suspected nosocomial infection out of a total of 254 patients. The frequency of nosocomial infection was 39.7%. UTI developed in 44.6%, while 27% had blood stream infection, and 21% had pneumonia. Each of the three major sites of infection was strongly associated with the use of invasive devices. Escherichia (E.) coli was the most common organism isolated followed by Pseudomonas aeruginosa and Klebsiella. E. coli and Klebsiella showed a maximum sensitivity to Imipenem followed by Tazocin (pipericillin + tazobactam). Pseudomonas aeruginosa was sensitive to Amikacin and Fosfomycin. The high frequency of nosocomial infection suggests that more strict measures regarding invasive devices should be taken in future to control the infection and limit the emergence of antibiotic resistant organisms.

Bloodstream infection (BSI) is one of the most common causes of nosocomial infection in neonatal intensive care units (NICU). The aim of the present study was to determine bacterial agents and their susceptibility patterns to antibiotics and to investigate the risk factors associated with BSI. This was a nested case-control study carried out from September 2009 to June 2010 in the NICU wards in Sanandaj hospitals western Iran. Cases were patients with BSI and controls were other patients who had negative blood culture. Bacteriologic diagnosis and antibiotic susceptibility pattern was performed based on the Edward & Ewings and the National Committee of Clinical Laboratory (NCCL) Standards. Of 472 patients who hospitalized in NICU, 6.4% had BSI (n = 30) including 17girls (56.7%) and 13 boys (43.3%). Enterobacter SPP was the predominant isolated bacteria from blood culture (36.7%). The maximum antibiotic resistance and sensitivity were observed by Tetracycline and Ciprofloxacin respectively. Risk factors associated with BSI were age ≤ 7 days (p = 0.001), previous antibiotic consumption (p = 0.013), and low birth weight (LBW), (p = 0.001). Gram negative bacteria and Entrobacter in particular are the most common pathogens. Improving prenatal health care, standards of infection control and choosing accurate antibiotics are recommended to avoid BSI in neonatal intensive care units.

To examine the effect of heterogeneous case mix for a benchmarking analysis and interhospital comparison of the prevalence rates of nosocomial infection. Cross-sectional survey. Eleven hospitals located in Cyprus and in the region of Crete in Greece. The survey included all inpatients in the medical, surgical, pediatric, and gynecology-obstetrics wards, as well as those in intensive care units. Centers for Disease Control and Prevention criteria were used to define nosocomial infection. The information collected for all patients included demographic characteristics, primary admission diagnosis, Karnofsky functional status index, Charlson comorbidity index, McCabe-Jackson severity of illness classification, use of antibiotics, and prior exposures to medical and surgical risk factors. Outcome data were also recorded for all patients. Case mix-adjusted rates were calculated by using a multivariate logistic regression model for nosocomial infection risk and an indirect standardization method.Results. The overall prevalence rate of nosocomial infection was 7.0% (95% confidence interval, 5.9%-8.3%) among 1,832 screened patients. Significant variation in nosocomial infection rates was observed across hospitals (range, 2.2%-9.6%). Logistic regression analysis indicated that the mean predicted risk of nosocomial infection across hospitals ranged from 3.7% to 10.3%, suggesting considerable variation in patient risk. Case mix-adjusted rates ranged from 2.6% to 12.4%, and the relative ranking of hospitals was affected by case-mix adjustment in 8 cases (72.8%). Nosocomial infection was significantly and independently associated with mortality (adjusted odds ratio, 3.6 [95% confidence interval, 2.1-6.1]). The first attempt to rank the risk of nosocomial infection in these regions demonstrated the importance of accounting for heterogeneous case mix before attempting interhospital comparisons.

Objective: Infections are a major cause of morbidity and mortality in systemic lupus erythematosus. Clinical outcomes of systemic lupus erythematosus patients hospitalized due to infections vary among different ethnic populations. Thus, we determined the outcomes and associated factors in a group of Hispanics from Puerto Rico with systemic lupus erythematosus admitted due to severe infections. Methods: Records of systemic lupus erythematosus patients admitted to the Adult University Hospital, San Juan, Puerto Rico, from January 2006 to December 2014 were examined. Demographic parameters, lupus manifestations, comorbidities, pharmacologic treatments, inpatient complications, length of stay, readmissions, and mortality were determined. Patients with and without infections were compared using bivariate and multivariate analyses. Results: A total of 204 admissions corresponding to 129 systemic lupus erythematosus patients were studied. The mean (standard deviation) age was 34.7 (11.6) years; 90% were women. The main causes for admission were lupus flare (45.1%), infection (44.0%), and initial presentation of systemic lupus erythematosus (6.4%). The most common infections were complicated urinary tract infections (47.0%) and soft tissue infections (42.0%). In the multivariate analysis, patients admitted with infections were more likely to have diabetes mellitus (odds ratio: 4.20, 95% confidence interval: 1.23–14.41), exposure to aspirin prior to hospitalization (odds ratio: 4.04, 95% confidence interval: 1.03–15.80), and higher mortality (odds ratio: 6.00, 95% confidence interval: 1.01–35.68) than those without infection. Conclusion: In this population of systemic lupus erythematosus patients, 44% of hospitalizations were due to severe infections. Patients with infections were more likely to have diabetes mellitus and higher mortality. Preventive and control measures of infection could be crucial to improve survival in these patients.

Urinary Tract Infection implies presence of actively multiplying organisms in the urinary tract. Although it is infrequently associated with mortality, it is still a significant cause of morbidity. Early diagnosis is critical to preserve renal function of growing kidney. Our purpose was to determine the clinical, microbiologic profile and antibiotic sensitivity of such infections in pediatric Urinary Tract Infection (UTI) patients at Dhulikhel Hospital. A hospital based prospective descriptive study of 135 children from 2 months to 16 years, with clinical diagnosis of urinary tract infection who visited the pediatric department of Dhulikhel Hospital over the period of 15 months were enrolled in the study. All patients underwent routine urine analysis and culture. Children with recurrent UTI underwent micturating cystourethrogram (MCUG). Children with recurrent UTI of more than two years and with feature of pyelonephritis underwent USG abdomen as well. Complications and response of the treatment was observed in all cases of UTI. All data were entered in Epidata and data analysis was done using spss 16 version. Among 135 children, 32.5% were male and 67.4% were female. Fever was the most common presenting symptom in 74.80% of patients followed by dysuria in 54.1%. Among these children 95.6% had significant pyuria and 45% had culture positive infection. Children who showed positive for bacteriuria, Escherichia coli (78.7%) was the most common organism and are more than 80% sensitive to Amikacin, Gentamicin, Ceftriaxone, Ofloxacin, Nalidixic acid, Imipenem and Vancomycin. Co-trimoxazole was the most common drug used for treatment with a mean drug respond time of (mean+/-S.D) of 2.21+/-.78 days. 2+/-. Children who had recurrent UTI were more prone to develop culture positive UTI (p=0.0001). Urinary Tract Infection in female was almost twice more common than in male. Cotrimoxazole was the most common drug used for treatment, sensitivity of this drug was less than 50% for

The aim of this study was to determine the incidence and associates of bacterial infection severe enough to require hospitalization in well-characterized community-based patients with type 2 diabetes. METHODS AND FINDINGS: We studied a cohort of 1,294 patients (mean±SD age 64.1±11.3 years from the longitudinal observational Fremantle Diabetes Study Phase I (FDS1 and 5,156 age-, gender- and zip-code-matched non-diabetic controls. The main outcome measure was incident hospitalization for bacterial infection as principal diagnosis between 1993 and 2010. We also examined differences in statin use in 52 FDS1 pairs hospitalized with pneumonia (cases or a contemporaneous non-infection-related cause (controls. During 12.0±5.4 years of follow-up, 251 (19.4% patients were hospitalized on 368 occasions for infection (23.7/1,000 patient-years. This was more than double the rate in matched controls (incident rate ratio (IRR (95% CI, 2.13 (1.88-2.42, P<0.001.

Urinary tract infections are the most frequent healthcare associated infections, being related to both high costs and morbidity. Our intention was to carry out an epidemiological characterization of hospital acquired urinary tract infections that occurred in an internal medicine department of a Portuguese hospital. Retrospective cohort study (historic cohort). Data were analysed from a systematic random sample of 388 patients, representative of the 3492 admissions occurred in 2014 in that department. One in four patients underwent the placement of a bladder catheter [24.7% (n = 96); 95% CI: 20% - 29%], 36.5% (95% CI: 33% - 48%) of which in the absence of clinical criteria for that procedure. The global cumulative incidence rate for nosocomial urinary tract infections was 4.6% (95% CI: 2.5% - 6.7%). Most hospital acquired urinary tract infections (61.1%) were related to bladder catheter use. We quantified 3.06 infections / 1000 patient-days and 14.5 infections / 1000 catheter-days. Catheter associated urinary tract infection occurred at an early stage of hospitalization. The vast majority of patients (66.7%) that developed a catheter associated urinary tract infection were subjected to bladder catheter placement at emergency department. Seventy one per cent of catheter associated urinary tract infection occurred in patients that were subjected to bladder catheter placement without criteria. These results point to an excessive and inadequate use of urinary catheters, highlighting the need for judicious use taking into account the formal clinical indications. The incidence of catheter associated urinary tract infection is similar to what we found in other studies. Nevertheless we found a very high incidence density per catheter-days that may foresee a problem probably related to the absence of early withdrawal of the device, and to both bladder catheter placement and maintenance practices. A significant part of catheter associated urinary tract infection

Infections caused by methicillin-resistant Staphylococcus aureus (MRSA) incur significant costs. We aimed to examine the cost and cost-benefit of infection control interventions against MRSA and to examine factors affecting economic estimates. We performed a systematic review of studies assessing infection control interventions aimed at preventing spread of MRSA in hospitals and reporting intervention costs, savings, cost-benefit or cost-effectiveness. We searched PubMed and references of included studies with no language restrictions up to January 2012. We used the Quality of Health Economic Studies tool to assess study quality. We report cost and savings per month in 2011 US$. We calculated the median save/cost ratio and the save-cost difference with interquartile range (IQR) range. We examined the effects of MRSA endemicity, intervention duration and hospital size on results. Thirty-six studies published between 1987 and 2011 fulfilled inclusion criteria. Fifteen of the 18 studies reporting both costs and savings reported a save/cost ratio >1. The median save/cost ratio across all 18 studies was 7.16 (IQR 1.37-16). The median cost across all studies reporting intervention costs (n = 31) was 8648 (IQR 2025-19 170) US$ per month; median savings were 38 751 (IQR 14 206-75 842) US$ per month (23 studies). Higher save/cost ratios were observed in the intermediate to high endemicity setting compared with the low endemicity setting, in hospitals with 6 months. Infection control intervention to reduce spread of MRSA in acute-care hospitals showed a favourable cost/benefit ratio. This was true also for high MRSA endemicity settings. Unresolved economic issues include rapid screening using molecular techniques and universal versus targeted screening. © 2013 The Authors Clinical Microbiology and Infection © 2013 European Society of Clinical Microbiology and Infectious Diseases.

Knowledge sharing and organizational learning in the context of hospital infection prevention.

Recently, hospitals that have been successful in preventing infections have labeled their improvement approaches as either the Toyota Production System (TPS) approach or the Positive Deviance (PD) approach. PD has been distinguished from TPS as being a bottom-up approach to improvement, as against top-down. Facilities that have employed both approaches have suggested that PD may be more effective than TPS for infection prevention. This article integrates organizational learning, institutional, and knowledge network theories to develop a theoretical framework for understanding the structure and evolution of effective knowledge-sharing networks in health care organizations, that is, networks most conducive to learning and improvement. Contrary to arguments put forth by hospital success stories, the framework suggests that networks rich in brokerage and hierarchy (ie, top-down, "TPS-like" structures) may be more effective for learning and improvement in health care organizations, compared with a networks rich in density (ie, bottom-up, "PD-like" structures). The theoretical framework and ensuing analysis help identify several gaps in the literature related to organization learning and improvement in the infection prevention context. This, in turn, helps put forth recommendations for health management research and practice.

Environmental contamination in hospitals with antibiotic-resistant organisms (AROs) is associated with patient contraction of AROs. This study examined the working relationship of Infection Prevention and Control (IPAC) and Environmental Services and the impact of that relationship on ARO rates. Lead infection control professionals completed an online survey that assessed the IPAC and Environmental Services working relationship in their acute care hospital in 2011. The survey assessed cleaning collaborations, staff training, hospital cleanliness, and nosocomial methicillin-resistant Staphylococcus aureus (MRSA) infection, vancomycin-resistant Enterococcus (VRE) infection, and Clostridium difficile infection (CDI). The survey was completed by 58.3% of hospitals (119 of 204). Two-thirds (65.8%; 77 of 117) of the respondents reported that their cleaners were adequately trained, and 62.4% (73 of 117) reported that their hospital was sufficiently clean. Greater cooperation between IPAC and Environmental Services was associated with lower rates of MRSA infection (r = -0.22; P = .02), and frequent collaboration regarding cleaning protocols was associated with lower rates of VRE infection (r = -0.20; P = .03) and CDI (r = -0.31; P Environmental Services, and this was associated with lower rates of ARO. Deficits in the adequacy of cleaning staff training and hospital cleanliness were identified. The promotion of collaborative working relationships and additional training for Environmental Services workers would be expected to lower ARO rates.

To investigate the epidemiology of Clostridium difficile infection in Romanian hospitals. A survey was conducted at nine hospitals throughout Romania between November 2013 and February 2014. The survey identified 393 patients with Clostridium difficile infection. The median age was 67 years (range: 2-94 years); 56% of patients were aged >65 years. The mean prevalence of Clostridium difficile infection was 5.2 cases per 10.000 patient-days. The highest prevalences were 24.9 and 20 per 10.000 patient-days in hospitals specializing in gastroenterology and infectious diseases, respectively. Clostridium difficile infections were health care-associated in 70.5% patients and community-acquired in 10.2%. The origin was not determined in 19.3%. Clostridium difficile infection was severe in 12.3% of patients, and the in-hospital all-cause mortality was 8.8%. Polymerase chain reaction ribotype 027 had the highest prevalence in all participating hospitals and represented 82.6% of the total ribotyped isolates. The minimum inhibitory concentration of moxifloxacin was >4 μg/mL for 59 of 80 tested isolates (73.8%). Of 59 isolates, 54 were highly resistant to moxifloxacin (minimum inhibitory concentration ≥32 μg/mL), and the majority were polymerase chain reaction ribotype 027 (pClostridium difficile infections in Romania. In some specialized hospitals, the prevalence of Clostridium difficile infection was higher than the European mean prevalence, and this demonstrates the need for strict adherence to infection control programs.

We aimed to assess the current status of infectious diseases (ID), clinical microbiology (CM) and infection control (IC) staffing in hospitals and to analyse modifiers of staffing levels. We conducted an Internet-based survey of European Society of Clinical Microbiology and Infectious Diseases members and affiliates, collecting data on hospital characteristics, ID management infrastructure, ID/IC-related activities and the ratio of physicians per 100 hospital beds. Regression analyses were conducted to examine factors associated with the physician-bed ratio. Five hundred sixty-seven hospital responses were collected between April and June 2015 from 61 countries, 81.2% (384/473) from Europe. A specialized inpatient ward for ID patients was reported in 58.4% (317/543) of hospitals. Rates of antibiotic stewardship programmes (ASP) and surveillance activities in survey hospitals were high, ranging from 88% to 90% for local antibiotic guidelines and 70% to 82% for programmes monitoring hospital-acquired infections. The median ID/CM/IC physician per 100 hospital beds ratio was 1.12 (interquartile range 0.56-2.13). In hospitals performing basic ASP and IC (including local antibiotic guidelines and monitoring device-related or surgical site infections), the ratio was 1.21 (interquartile range 0.57-2.14). Factors independently associated with higher ratios included compliance with European Union of Medical Specialists standards, smaller hospital size, tertiary-care institution, presence of a travel clinic, beds dedicated to ID and a CM unit. More than half of respondents estimated that additional staffing is needed for appropriate IC or ID management. No standard of physician staffing for ID/CM/IC in hospitals is available. A ratio of 1.21/100 beds will serve as an informed point of reference enabling ASP and infection surveillance. Copyright © 2016 European Society of Clinical Microbiology and Infectious Diseases.

Full Text Available Infectious diseases of the central nervous system (CNS remain common and life-threatening, especially in developing countries. Knowledge of the aetiological agents responsible for these infections is essential to guide empiric therapy and develop a rational public health policy. To date most data has come from patients admitted to tertiary referral hospitals in Asia and there is limited aetiological data at the provincial hospital level where most patients are seen.We conducted a prospective Provincial Hospital-based descriptive surveillance study in adults and children at thirteen hospitals in central and southern Viet Nam between August 2007-April 2010. The pathogens of CNS infection were confirmed in CSF and blood samples by using classical microbiology, molecular diagnostics and serology.We recruited 1241 patients with clinically suspected infection of the CNS. An aetiological agent was identified in 640/1241 (52% of the patients. The most common pathogens were Streptococcus suis serotype 2 in patients older than 14 years of age (147/617, 24% and Japanese encephalitis virus in patients less than 14 years old (142/624, 23%. Mycobacterium tuberculosis was confirmed in 34/617 (6% adult patients and 11/624 (2% paediatric patients. The acute case fatality rate (CFR during hospital admission was 73/617 (12% in adults and to 42/624 (7% in children.Zoonotic bacterial and viral pathogens are the most common causes of CNS infection in adults and children in Viet Nam.

Urinary tract infections are among the most common infections after liver transplant, especially soon after surgery. This study analyzed urinary tract infections or bacteriuria, their causative agents, and related risk factors in the early period after liver transplant in hospitalized adult transplant recipients in the main liver transplant referral center in Iran. In this prospective study, 389 consecutive adult patients who underwent liver transplant at the Nemazee Teaching Hospital were enrolled between October 2014 and October 2015. Risk factors were compared for patients who developed urinary tract infections or bacteriuria ("infection group "; n = 63 [16.2% ]) and patients without evidence of infection ("control group "; n = 211 [54.2% ]). Patients with sites of infection other than the urinary tract were excluded. Antimicrobial sus ceptibility testing was performed using the Kirby-Bauer disk-diffusion method. Univariate and multivariate analyses compared variables between the 2 groups. Seventy-nine episodes of urinary tract infections or bacteriuria occurred in the infection group. Multiple logistic regression analysis showed that female sex, hospitalization 2 to 7 days before transplant, and frequency of abdominal exploration were 11.0, 5.9, and 3.0 times more common in the infection group than in the control group. The chance of infection rises 1.1 times with each one unit increase of body mass index. The most common infection causes were gram-negative bacteria (n = 50; 63.3%), predominantly Escherichia coli (n = 24; 30.4%); followed by gram-positive bacteria (n = 20; 25.3%), predominantly Enterococcus species (n = 14; 17.8%) that had a high incidence of vancomycin resistance (n = 10; 71.4%); and non-Candida albicans species isolates (n = 9; 11.4%). Urinary tract infections are a common infection in hospitalized adult patients soon after liver transplant. Female sex, hospitalization shortly before transplant, more frequent abdominal exploration, and higher

Full Text Available Background: The risk of pacemaker pocket infections (PPIs is rare with good antisepsis techniques and use of advanced antibiotics. However, injudicious antibiotic usage leads to the rise of multidrug-resistant bacteria, which may cause PPI. Few reports exist about the microbial spectrum of the PPI from our country, prompting us to study the same. Methods: We conducted this retrospective observational study for 3 years (January 2013–February 2016 from all the patients with PPI. We collected the relevant clinical samples (blood and pus for the microbial culture using a standard protocol. We included 100 samples collected from the medical staff and the hospital environment as a control sample. The data were analyzed using appropriate statistical methods and a P< 0.05 was considered statistically significant. Results: Our data showed that 17 out of 160 (10.6% patients had PPI. Coagulase negative Staphylococcus sp. was isolated in 7 (41.2% patients, followed by Staphylococcus aureus in 4 patients (23.5%. Other isolated bacteria include multidrug-resistant Burkholderia cepacia (n = 3, Mycobacterium abscessus (n = 2 and polymicrobial infection in a single patient. One out of hundred surveillance samples grew B. cepacia. Conclusion: Our data revealed a high incidence of Gram-positive cocci causing PPI. Every hospital should formulate their antibiotic policy based on the pattern of the hospital flora and their drug sensitivity.

The monitoring and genotyping of Enterovirus (EV) infections can help to associate particular or severe clinical manifestations with specific EV types and to identify the aetiology of infectious outbreaks. To describe the epidemiological features of EV infections diagnosed during the year 2013 in the Greater Paris area (Ile de France). During 2013, 2497 samples taken from 470 patients in 33 hospitals of Ile-de France were tested for EV genome by RT-PCR. EV genotyping was performed by the National Reference Centre (NRC) laboratories. EV infections were retrospectively reviewed by retrieving clinical and genotyping data from the NRC database. Of the 2497 samples, 490 (19.6%) was positive for EV genome detection. These EV infections represented 88.7% and 24.1%, respectively, of all reported regional and national infections. Twenty-seven different genotypes were identified. Echovirus 30 (E-30) accounted for 54.1% of all characterized strains and caused a large outbreak. Four severe neonatal infections were reported, of which two were caused by EV-A71. Respiratory infections involving EV-D68 were observed in two adults. One fatal case of Coxsackievirus A2-associated myocarditis was reported. Monitoring EV infections in combination with EV genotyping via the French EV network characterized the epidemiology of EV infections in the Ile de France region in 2013 and documented severe EV infections associated with EV-A71 or CV-A2.

To identify potential risk factors associated with endogenous endophthalmitis among hospitalized patients with hematogenous infections. Retrospective cross-sectional study. MarketScan Commercial Claims and Encounters, and Medicare Supplemental and Coordination of Benefit inpatient databases from the years 2007-2011 were obtained. Utilizing ICD-9 codes, logistic regression was used to identify potential predictors/comorbidities for developing endophthalmitis in patients with hematogenous infections. Among inpatients with hematogenous infections, the overall incidence rate of presumed endogenous endophthalmitis was 0.05%-0.4% among patients with fungemia and 0.04% among patients with bacteremia. Comorbid human immunodeficiency virus infection/acquired immunodeficiency syndrome (HIV/AIDS) (OR = 4.27; CI, 1.55-11.8; P = .005), tuberculosis (OR = 8.5; CI, 1.2-61.5; P = .03), endocarditis (OR = 8.3; CI, 4.9-13.9; P endogenous endophthalmitis.

To understand protozoan, viral, and bacterial infections in diarrheal patients, we analyzed positivity and mixed-infection status with 3 protozoans, 4 viruses, and 10 bacteria in hospitalized diarrheal patients during 2004-2006 in the Republic of Korea. A total of 76,652 stool samples were collected from 96 hospitals across the nation. The positivity for protozoa, viruses, and bacteria was 129, 1,759, and 1,797 per 10,000 persons, respectively. Especially, Cryptosporidium parvum was highly mixed-infected with rotavirus among pediatric diarrheal patients (29.5 per 100 C. parvum positive cases), and Entamoeba histolytica was mixed-infected with Clostridium perfringens (10.3 per 100 E. histolytica positive cases) in protozoan-diarrheal patients. Those infected with rotavirus and C. perfringens constituted relatively high proportions among mixed infection cases from January to April. The positivity for rotavirus among viral infection for those aged ≤ 5 years was significantly higher, while C. perfringens among bacterial infection was higher for ≥ 50 years. The information for association of viral and bacterial infections with enteropathogenic protozoa in diarrheal patients may contribute to improvement of care for diarrhea as well as development of control strategies for diarrheal diseases in Korea.

The consequences of the HIV epidemic on cancer epidemiology are sparsely documented in Africa. We aimed to estimate the association between HIV infection and selected types of cancers among patients hospitalized for cancer in four West African countries. A case-referent study was conducted in referral hospitals of Benin, Côte d'Ivoire, Nigeria and Togo. Each participating clinical ward included all adult patients seeking care with a confirmed diagnosis of cancer. All patients were systematically screened for HIV infection. HIV prevalence of AIDS-defining and some non-AIDS defining cancers (Hodgkin lymphoma, leukemia, liver, lung, skin, pharynx, larynx, oral cavity and anogenital cancers) were compared to a referent group of cancers reported in the literature as not associated with HIV. Odds ratios adjusted on age, gender and lifetime number of sexual partners (aOR) and their 95% confidence intervals (CI) were estimated. Among the 1644 cancer patients enrolled, 184 (11.2%) were identified as HIV-infected. The HIV prevalence in the referent group (n=792) was 4.4% [CI 3.0-5.8]. HIV infection was associated with Kaposi sarcoma (aOR 34.6 [CI: 17.3-69.0]), non-Hodgkin lymphoma (aOR 3.6 [CI 1.9-6.8]), cervical cancer (aOR 4.3 [CI 2.2-8.3]), anogenital cancer (aOR 17.7 [CI 6.9-45.2]) and squamous cell skin carcinoma (aOR 5.2 [CI 2.0-14.4]). A strong association is now reported between HIV infection and Human Papillomavirus (HPV)-related cancers including cervical cancer and anogenital cancer. As these cancers are amenable to prevention strategies, screening of HPV-related cancers among HIV-infected persons is of paramount importance in this African context. Copyright © 2015 Elsevier Ltd.

The aim of the paper is to describe the criteria used for identification of first and so far the only one outbreak of hospital bacterial infections due to L. pneumophila. The infected persons were patients hospitalized at ophthalmic ward for more than 10 days. Four patients were found ill among 27 hospitalized (15%) at ophthalmic ward and 3 of them died (75%) in spite treatment in intensive care unit. The source of infection was found in the hospital hot water system. It was shown that L. pneumophila sg 1 and sg 2-14 were settled in the tanks and pipelines of hot water installations. The high number of L. pneumophila sg I and sg 2-14 colony forming units (> 10 000 cfu /100 ml) were found in the water specimens taken from the hospital water system, showing the high risk of Legionella infection for patients. Cleaning and disinfection of hot water system was repeated three times using composition every time modified as stronger mechanical, thermal and chemical methods. Complete elimination of Legionella from hot water system was achieved after cutting off deadlegs of water and replacement of both old hot water reservoirs with new ones. Collected experience served for preparation of guidelines for control and prevention of Legionella infections in hospital buildings, published on National Institute of Hygiene web site A month later Polish Ministry of Health published the Directives concerning the quality of drinking water to which the control of Legionella infection has been included.

There are limited data on the epidemiology of paediatric healthcare-associated infection (HCAI) and infection control in low-income countries. We describe the value of intermittent point-prevalence surveys for monitoring HCAI and evaluating infection control interventions in a Cambodian paediatric hospital. Hospital-wide, point-prevalence surveys were performed monthly in 2011. Infection control interventions introduced during this period included a hand hygiene programme and a ventilator-associated pneumonia (VAP) care bundle. Overall HCAI prevalence was 13.8/100 patients at-risk, with a significant decline over time. The highest HCAI rates (50%) were observed in critical care; the majority of HCAIs were respiratory (61%). Klebsiella pneumoniae was most commonly isolated and antimicrobial resistance was widespread. Hand hygiene compliance doubled to 51.6%, and total VAP cases/1000 patient-ventilator days fell from 30 to 10. Rates of HCAI were substantial in our institution, and antimicrobial resistance a major concern. Point-prevalence surveys are effective for HCAI surveillance, and in monitoring trends in response to infection control interventions.

The physical design of hospital wards is associated with transmission of pathogenic organisms and hospital-acquired infections. A novel hospital unit, the Medical Ward of the 21st Century (W21C), optimizes features for infection prevention and control practices. Ethnographic research on the W21C versus conventional hospital wards examined the experiential and behavioural elements of the different designs. Three recurring themes emerged regarding the design features on the W21C and included visual cues, 'having a place for things', and less sharing of spaces and materials. Observational data of healthcare worker practices demonstrated significantly higher compliance with hand hygiene opportunities on the W21C compared with older hospital units. These findings suggest how the physical design of a hospital ward may enhance infection prevention and control practices.

Full Text Available Abstract Background Many hospitalizations for residents of skilled nursing facilities are potentially avoidable. Factors that could prevent hospitalization for urinary tract infection (UTI were investigated, with focus on patient mobility. Methods A retrospective cohort study was conducted using 2003–2004 data from the Centers for Medicare and Medicaid Services. The study included 408,192 residents of 4267 skilled nursing facilities in California, Florida, Michigan, New York, and Texas. The patients were followed over time, from admission to the skilled nursing facility to discharge or, for those who were not discharged, for 1 year. Cox proportional hazards regression was conducted with hospitalization for UTI as the outcome. Results The ability to walk was associated with a 69% lower rate of hospitalization for UTI. Maintaining or improving walking ability over time reduced the risk of hospitalization for UTI by 39% to 76% for patients with various conditions. For residents with severe mobility problems, such as being in a wheelchair or having a missing limb, maintaining or improving mobility (in bed or when transferring reduced the risk of hospitalization for UTI by 38% to 80%. Other potentially modifiable predictors included a physician visit at the time of admission to the skilled nursing facility (Hazard Ratio (HR, 0.68, use of an indwelling urinary catheter (HR, 2.78, infection with Clostridium difficile or an antibiotic-resistant microorganism (HR, 1.20, and use of 10 or more medications (HR, 1.31. Patient characteristics associated with hospitalization for UTI were advancing age, being Hispanic or African-American, and having diabetes mellitus, renal failure, Parkinson's disease, dementia, or stroke. Conclusion Maintaining or improving mobility (walking, transferring between positions, or moving in bed was associated with a lower risk of hospitalization for UTI.

Monitoring of prevalence and antibiotic susceptibility of strictly anaerobic bacteria, causing infections in hospitalized patients, constitutes a part of a program for prudent use of antibiotics. The aim of the study was to assess prevalence of strictly anaerobic bacteria in patients hospitalized in a tertiary care hospital in 2001-2002 with reference to empiric antibiotic therapy. The most common gram-positive bacteria were Clostridium difficile--27.7%, Peptostreptococcus spp. and Peptoniphilus asaccharolyticus--21.9% and Actinomyces spp.--11.1%. There was an increase in the number of stool samples positive for C. difficile toxins A and B from 39.4% in 2001 to 59.0% in 2002. The results of susceptibility testing of gram-positive isolates showed the highest percentages of strains susceptible to piperacilin/tazobactam--99.6%, ticarcillin/clavulanate--98.5%, imipenem--98.5%, amoxicillin/clavulanate--97.4% and piperacillin--97.4%. The most prevalent gram-negative anaerobes were strains of Bacteroides spp.--43.1%, Prevotella spp.--35.8% and Fusobacterium spp.--11.0%. All tested strains of gram-negative bacteria were susceptible to metronidazole, piperacilin/tazobactam, ticarcillin/clavulanate and imipenem. In the analyzed population beta-lactam antibiotics with beta-lactamase inhibitors, carbapenems and metronidazole may be used in empiric therapy of infections caused by strictly anaerobic bacteria.

Urinary tract infection in children is well recognized as a cause of acute morbidity and chronic medical conditions. As a result, appropriate use of antimicrobial agents, however, increases antibiotic resistance and complicates its treatment due to increased patient morbidity, costs, rates of hospitalization, and use of broader-spectrum antibiotics. The goal of this study was to determine antibiotic susceptibility to commonly used agents for urinary tract infection against recent urinary isolates. A total of 457 consecutive children attending the emergency room at the Hospital Infantil de México Federico Gómez with symptoms of uncomplicated lower urinary tract infection were eligible for inclusion. Patients who had had symptoms for≥7 days and those who had had previous episodes of urinary tract infection, received antibiotics or other complicated factors were excluded. Midstream and catheter urine specimens were collected. All isolates were identified and the in vitro activities of antimicrobials were determined. The most frequently isolated urinary pathogens were as follows: Escherichia coli (E. coli) (312, 68.3%), Enterococcus spp. (42, 11%), Klebsiella pneumoniae (K. pneumoniae) (40, 8.7%), Pseudomonas aeruginosa (P. aeruginosa) (34, 7.5%), Proteus mirabilis (P. mirabilis) (21, 4.5%), Enterobacter cloacae (8, 1.7%). The resistance to trimetoprim/sulfametoxazol (%) was 73.7, 62.2, 100, 52, and 50, respectively, for E. coli, K. pneumoniae, P. aeruginosa, P. mirabilis and Enterobacter spp., 92.5 for Enterococcus faecalis (E. faecalis) and 49.9 for Enterococcus faecium (E. faecium). Ampicillin was 86.3, 45, 100, 47.9, and 66.6% for the same strains, ciprofloxacin 33.8, 9, 18.8, 0, 0%, nitrofurantoin 4.4, 13, 97.7, 70, 0%; to E. faecalis 0% and 16.7% to E. faecium. Frequently prescribed empirical agents for uncomplicated urinary tract infection demonstrate lowered in vitro susceptibilities when tested against recent clinical isolates. Copyright © 2014 Hospital

The prosthetic joint infection is the most feared and catastrophic complication for cause severe physical damage to patients and, generates high economic costs. To describe the microbiological characteristics and to determine the resistance pattern in prosthetic joint infections in a reference hospital in Mexico. Patients whose prosthetic devices were withdrawn due to suspicion of septic and aseptic loosening were included. Cultures were performed to identify microorganisms and susceptibility analysis. Of the 111 patients included, 55% were diagnosed with prosthetic joint infection, with the most frequent prosthesis being of the hip (43%). Positive cultures were obtained in 97% of the infected cases, of which 75% were monomicrobial infections. The most frequent bacterial species isolated were: Staphylococcus epidermidis (31%), Enterococcus faecalis (16%), Staphylococcus aureus (13%), and Escherichia coli (8%). The resistance patterns for the Staphylococcus genus were: oxacillin (79%), erythromycin (45%) and ciprofloxacin (37%). Enterococcus faecalis showed a high percentage of resistance to erythromycin and clindamycin (86%), and fluoroquinolones (43%). The large majority (86%) of Escherichia coli were extended spectrum beta-lactamases positive, in addition to having high resistance to fluoroquinolones (86%), trimethoprim/sulfamethoxazole (86%) and gentamicin (72%). The microbiological characteristics found in prosthetic joint infections vary according to the hospitals. In this series, a high proportion of coagulase-negative Staphylococci and Enterococcus spp. were found, as well as a high bacterial resistance. Copyright © 2015 Academia Mexicana de Cirugía A.C.

Hospital-acquired urinary tract infection point prevalence in Turkey: Differences in risk factors among patient groups

Science.gov (United States)

2013-01-01

Background The aim of this study was to determine the point prevalence of nosocomial urinary tract infections (UTIs) and to investigate risk factors for pathogen type (E. coli vs. others) and extended-spectrum beta-lactamase (ESBL) positivity among nosocomial UTI patients. Methods A questionnaire consisting of 44 questions on demographic data and risk factors of UTI cases was sent to 51 tertiary care hospitals. Univariate and multivariate analyses were conducted. Results The overall prevalence of UTI was 1.82% (483/26534). The prevalence of UTI was higher in intensive care units (ICUs) with 6.77% versus 1.45% outside ICUs. Hospitals of the Ministry of Health (compared to university hospitals), hospitals in less developed provinces and hospitals with bed capacity urinary catheter were more likely to have received immunosuppressive therapy, current corticosteroid use, renal transplantation and uterine prolapsus and less likely to have another infection outside the urinary tract, as compared to catheterized patients. Among the 422 culture-positive patients, the most common pathogen was E. coli (45.5%). The risk factors increasing the likelihood of E. coli in urine culture were being female, history of urinary tract operation, no use of antibiotics in the preceding three months and infection outside the urinary tract. There were 247 patients with E. coli or Klebsiella spp. positive in culture. Among these, 61% (n=151) were ESBL- positive. Among patients having E. coli/Klebsiella positive in culture, antibiotic use in the preceding three months and history of urinary tract operation were the independent risk factors significantly increasing the risk of ESBL. Conclusions The reasons underlying the high prevalence of nosocomial UTIs, and a better understanding of the risk factors might lead to improved control of these infections. PMID:24188193

To determine the incidence and outcomes of respiratory syncytial virus (RSV)-related acute lower respiratory tract infection (ALRI) including morbidity, nosocomial infection and mortality among newborn infants who were admitted to the neonatal intensive care units (NICUs). A multicenter, prospective study was conducted in newborns who were hospitalized with community acquired or nosocomial RSV infection in 44 NICUs throughout Turkey. Newborns with ALRI were screened for RSV infection by Respi-Strip®-test. Main outcome measures were the incidence of RSV-associated admissions in the NICUs and morbidity, mortality and epidemics results related to these admissions. The incidence of RSV infection was 1.24% (n: 250) and RSV infection constituted 19.6% of all ALRI hospitalizations, 226 newborns (90.4%) had community-acquired whereas 24 (9.6%) patients had nosocomial RSV infection in the NICUs. Of the 250 newborns, 171 (68.4%) were full-term infants, 183 (73.2%) had a BW >2500 g. RSV-related mortality rate was 1.2%. Four NICUs reported seven outbreaks on different months, which could be eliminated by palivizumab prophylaxis in one NICU. RSV-associated ALRI both in preterm and term infants accounts an important percent of hospitalizations in the season, and may threat other high-risk patients in the NICU.

During prospective epidemiological surveillance cases of pyogenic and septic infections (PSI) in mothers and newborns in two maternity hospitals were studied using standard case definition and leading risk factors of their development were revealed. These factors differed in two hospitals and were connected mainly with high level of patients colonization, contamination of the environment by nosocomial strains of microorganisms, and degree of participation of mother's relatives in delivery. It was shown that permission to relatives for presence on delivery did not influence on the rate of PSI. Specificity of risk factors of PSI in mothers and newborns dictates necessity to determine them in each maternity hospital.

A Quality Improvement Approach to Reducing the Caesarean section Surgical Site Infection Rate in a Regional Hospital

LENUS (Irish Health Repository)

O’ Hanlon, M

2016-09-01

Surgical site infection (SSI) rates are used extensively by hospitals as a basis for quality improvement. A 30-day post-discharge SSI programme for Caesarean section operations has been implemented in Our Lady of Lourdes Hospital since 2011. It has been shown that skin antisepsis and antibiotic prophylaxis are key factors in the prevention of SSI. Using quality improvement methodology, an infection prevention bundle was introduced to address these two factors. Skin antisepsis was changed from povidone-iodine to chlorhexidine-alcohol. Compliance with choice of antibiotic prophylaxis increased from 89.6% in 2014 to 98.5% in 2015. Compliance with timing also improved. The SSI rate of 7.5% was the lowest recorded to date, with the majority of SSIs (64%) diagnosed after hospital discharge. The level of variation was also reduced. However, the continued presence of variation and possibility of lower infection rates from the literature imply that further improvements are required.

Prevention of Clostridium difficile infection (CDI) remains challenging across the spectrum of health care. There are limited data on prevention practices for CDI in the rural health care setting. An electronic survey was administered to 21 rural facilities in Wisconsin, part of the Rural Wisconsin Health Cooperative. Data were collected on hospital characteristics and practices to prevent endemic CDI. Fifteen facilities responded (71%). Nearly all respondent facilities reported regular use of dedicated patient care items, use of gown and gloves, private patient rooms, hand hygiene, and room cleaning. Facilities in which the infection preventionist thought the support of his/her leadership to be "Very good" or "Excellent" employed significantly more CDI practices (13.3 ± 2.4 [standard deviation]) compared with infection preventionists who thought there was less support from leadership (9.8 ± 3.0, P = .033). Surveillance for CDI was highly variable. The most frequent barriers to implementation of CDI prevention practices included lack of adequate resources, lack of a physician champion, and difficulty keeping up with new recommendations. Although most rural facilities in our survey reported using evidence-based practices for prevention of CDI, surveillance practices were highly variable, and data regarding the impact of these practices on CDI rates were limited. Future efforts that correlate CDI prevention initiatives and CDI incidence will help develop evidence-based practices in these resource-limited settings. Published by Mosby, Inc.

To identify risk factors for Klebsiella pneumoniae bloodstream infections (BSI) in neonates in a hospital in the Kingdom of Saudi Arabia (KSA). Two case-control studies among hospitalized neonates during February 15-May 14, 1991, and a procedural and microbiological investigation. Hospital A, a maternity and children's hospital in KSA. Case patients had a blood culture positive for K pneumoniae after >2 days of hospitalization and had no evidence of a nonblood primary site of infection. When the 20 case patients were compared with controls, hospitalization in a critical-care unit (odds ratio [OR], 5.5; 95% confidence interval [CI95], 1.20-51.1; P=.03) was identified as a risk factor. When the case patients were compared with a second set of controls matched by critical-care status, receipt of a particular intravenous fluid (D10%/0.2NS; OR, 11.0; CI95, 1.42-85.2; P=.009) or a blood product (OR undefined; P=.04) were identified as risk factors. Infusates were administered via umbilical catheters for most case and control patients (19/20 vs 15/20, P>.05); catheters were manipulated more frequently in patients in critical-care units. Umbilical catheter tip, skin, or mucus membrane K pneumoniae colonization occurred in 47% and 53% of evaluated case and control patients, respectively. Available K pneumoniae isolates from blood cultures and colonization sites had identical antimicrobial susceptibility patterns. Emphasis on handwashing, careful preparation and administration of infusates, and aseptic technique for catheter insertion, maintenance, and manipulation was temporally associated with resolution of the epidemic. This outbreak was probably due to infusion therapy practices that led to BSI in nursery patients colonized with K pneumoniae. Both catheter-related infections and extrinsic contamination of infusates may have occurred. Hospital personnel should be aware of their potential to spread nosocomial pathogens from person to person and should implement Centers for

Background Hospital-acquired infections (HAIs) are infections that patients contract while in the hospital that were neither present nor developing at the time of admission. In Canada an estimated 10% of adults with short-term hospitalization have HAIs. According to 2003 Canadian data, between 4% and 6% of these patients die from these infections. The most common HAIs in Ontario are caused by Clostridium difficile. The standard method of reducing and preventing these infections is decontamination of patient rooms through manual cleaning and disinfection. Several portable no-touch ultraviolet (UV) light systems have been proposed to supplement current hospital cleaning and disinfecting practices. Methods We searched for studies published from inception of UV disinfection technology to January 23, 2017. We compared portable UV surface-disinfecting devices used together with standard hospital room cleaning and disinfecting versus standard hospital cleaning and disinfecting alone. The primary outcome was HAI from C. difficile. Other outcomes were combined HAIs, colonization (i.e., carrying an infectious agent without exhibiting disease symptoms), and the HAI-associated mortality rate. We used Grading of Recommendations Assessment, Development, and Evaluation (GRADE) to rate the quality of evidence of included studies. We also performed a 5-year budget impact analysis from the hospital's perspective. This assessment was limited to portable devices and did not examine wall mounted devices, which are used in some hospitals. Results The database search for the clinical review yielded 10 peer-reviewed publications that met eligibility criteria. Three studies focused on mercury UV-C–based technology, seven on pulsed xenon UV technology. Findings were either inconsistent or produced very low-quality evidence using the GRADE rating system. The intervention was effective in reducing the rate of the composite outcome of HAIs (combined) and colonization (but quality of evidence

To study the transmission route of severe acute respiratory syndrome (SARS) nosocomial infection. Ten identified SARS patients were selected from a general hospital in March. Survey was carried out through a standardized questionnaire provided by Chinese Center for Disease Control and Prevention. Contents of the questionnaire would include: history of contact with SARS patient, route of infection, methods used for protection and so on. (1) Distribution os SARS patients were confined to 3 wards: 4, 5, and 6 on the 7, 8, 12, 13 and 14 floors in the west unit of the inpatient building. Most of the inpatients were elderly and having severe original diseases. (2) Index patients were the first generation source of transmission and they infected inpatients and medical staff, making them the second generation. People with latent infection who had close contact with SARS patients might also serve as the possible source of transmission. (3) The major transmission routes were: near distant droplet infection and close contact infection. There was also a clue to the probability of aerosol or droplet nuclei infection through air-conditioning and ventilation system. Nosocomial infection appeared to be the main characteristic of the SARS epidemic in the early stage of this hospital. Other than close contact and near space airborne transmission of SARS virus, the possibility of long-distance aerosol transmission called for further epidemiological and experimental studies in the future.

Background: Patients undergoing open heart surgery have a relatively high risk of acquiring nosocomial infections. The development of antibiotic-resistant infections is associated with prolonged hospital stays and mortalities. Objectives: The present study was conducted to investigate nosocomial infections and the antibiotic resistance pattern in bacteria causing these infections in open heart surgery patients at Imam Ali Hospital in Kermanshah in the west of Iran over a 4-year period from March 2011 to March 2014. Materials and methods: The present cross-sectional study was conducted on 135 cases of nosocomial infection among open heart surgery patients. The demographic characteristics and the risk factors of each case of infection were recorded. The antibiotic susceptibility test was carried out using the Minimum Inhibitory Concentration (MIC) method based on the Clinical and Laboratory Standards Institute (CLSI) protocol. The data collected were then analyzed in SPSS-16. Results: Out of the 6,000 patients who underwent open heart surgery during this 4-year period at the selected hospital, nosocomial infections developed in 135 patients (2.25%), 59.3% of whom were female and 40.7% male. Surgery site infection (SSI), pneumonia (PNEU), urinary tract infection (UTI) and blood stream infection (BSI) affected 52.6%, 37%, 9.6% and 0.8% of the cases, respectively. E.coli , Klebsiella spp. and S. aureus were the most common bacteria causing the nosocomial infections. E. coli was most frequently resistant to imipenem (23.3%) Klebsiella spp. to gentamicin (38.5%) S. aureus to co-trimoxazole (54.2%). Conclusion: SSI had a high prevalence in this study. Further studies should therefore be conducted to examine the risk factors associated with SSI in open heart surgery. Various studies have shown that antibiotic resistance patterns are different in different regions. Finding a definitive treatment therefore requires an antibiogram.

Objective: To analyze the pathogens of lower respiratory tract infection(LRTI) including bacterial, viral and mixed infection, and to establish a discriminant model based on clinical features in order to predict the pathogens. Methods: A total of 243 hospitalized patients with lower respiratory tract infections were enrolled in Fujian Provincial Hospital from April 2012 to September 2015. The clinical data and airway (sputum and/or bronchoalveolar lavage) samples were collected. Microbes were identified by traditional culture (for bacteria), loop-mediated isothermal amplification(LAMP) and gene sequencing (for bacteria and atypical pathogen), or Real-time quantitative polymerase chain reaction (Real-time PCR)for viruses. Finally, a discriminant model was established by using the discriminant analysis methods to help to predict bacterial, viral and mixed infections. Results: Pathogens were detected in 53.9% (131/243) of the 243 cases.Bacteria accounted for 23.5%(57/243, of which 17 cases with the virus, 1 case with Mycoplasma pneumoniae and virus), mainly Pseudomonas Aeruginosa and Klebsiella Pneumonia.

Gastrointestinal Infections have been implicated as possible causes of exacerbation of inflammatory bowel disease (IBD) or risk factors for severe flares in general. The introduction of the G-DRG reimbursement system has greatly increased the pressure to provide cost effective treatment in German hospitals. Few studies have compared the costs of treating IBD patients with or without gastrointestinal infections and none of them have specifically considered the German reimbursement situation. We performed a single center case-control retrospective chart review from 2002 to 2011 of inpatients with IBD (Department of Internal Medicine IV, University Hospital Jena) with an exacerbation of their disease. The presence of gastrointestinal infections (Salmonella, Shigella, Campylobacter, Yersinia, adeno-, rota-, norovirus and Clostridium difficile) was assessed in all inpatients with Cohn's disease (CD) and ulcerative colitis (UC). IBD patients with gastrointestinal infections (n = 79) were matched for age to IBD patients who were negative for gastrointestinal pathogens (n = 158). Patient level costing (PLC) was used to express the total cost of hospital care for each patient; PLC comprised a weighted daily bed cost plus cost of all medical services provided (e. g., endoscopy, microbiology, pathology) calculated according to an activity-based costing approach. All costs were discounted to 2012 values. Gastrointestinal infections in IBD patients were not associated with an increase in mortality (0%); however, they were associated with 2.3-fold higher total hospital charges (6499.10 € vs. 2817.00 €; p = 0.001) and increased length of stay in hospital (14.5 vs. 9.4 days; p costs, especially in UC. Inpatient hospital costs differ significantly for IBD patients with and without gastrointestinal infections, especially in ulcerative colitis, when care was provided in a single university hospital. © Georg Thieme Verlag KG Stuttgart · New York.

BACKGROUND High-quality cost estimates for hospital-acquired Clostridium difficile infection (CDI) are vital evidence for healthcare policy and decision-making. OBJECTIVE To evaluate the costs attributable to hospital-acquired CDI from the healthcare payer perspective. METHODS We conducted a population-based propensity-score matched cohort study of incident hospitalized subjects diagnosed with CDI (those with the International Statistical Classification of Diseases and Related Health Problems, 10th Revision, Canada code A04.7) from January 1, 2003, through December 31, 2010, in Ontario, Canada. Infected subjects were matched to uninfected subjects (those without the code A04.7) on age, sex, comorbidities, geography, and other variables, and followed up through December 31, 2011. We stratified results by elective and nonelective admissions. The main study outcomes were up-to-3-year costs, which were evaluated in 2014 Canadian dollars. RESULTS We identified 28,308 infected subjects (mean annual incidence, 27.9 per 100,000 population, 3.3 per 1,000 admissions), with a mean age of 71.5 years (range, 0-107 years), 54.0% female, and 8.0% elective admissions. For elective admission subjects, cumulative mean attributable 1-, 2-, and 3-year costs adjusted for survival (undiscounted) were $32,151 (95% CI, $28,192-$36,005), $34,843 ($29,298-$40,027), and $37,171 ($30,364-$43,415), respectively. For nonelective admission subjects, the corresponding costs were $21,909 ($21,221-$22,609), $26,074 ($25,180-$27,014), and $29,944 ($28,873-$31,086), respectively. CONCLUSIONS Hospital-acquired CDI is associated with substantial healthcare costs. To the best of our knowledge, this study is the first CDI costing study to present longitudinal costs. New strategies may be warranted to mitigate this costly infectious disease. Infect Control Hosp Epidemiol 2016;37:1068-1078.

Ward closure is a method of controlling hospital-acquired infectious diseases outbreaks and is often coupled with other practices. However, the value and efficacy of ward closures remains uncertain. To understand the current practices and perceptions with respect to ward closure for hospital-acquired infectious disease outbreaks in acute care hospital settings across Canada. A Web-based environmental scan survey was developed by a team of infection prevention and control (IPC) experts and distributed to 235 IPC professionals at acute care sites across Canada. Data were analyzed using a mixed-methods approach of descriptive statistics and thematic analysis. A total of 110 completed responses showed that 70% of sites reported at least 1 outbreak during 2013, 44% of these sites reported the use of ward closure. Ward closure was considered an "appropriate," "sometimes appropriate," or "not appropriate" strategy to control outbreaks by 50%, 45%, and 5% of participants, respectively. System capacity issues and overall risk assessment were main factors influencing the decision to close hospital wards following an outbreak. Results suggest the use of ward closure for containment of hospital-acquired infectious disease outbreaks in Canadian acute care health settings is mixed, with outbreak control methods varying. The successful implementation of ward closure was dependent on overall support for the IPC team within hospital administration.

Management of pressure ulcers (PrUs) in patients with gunshot-spinal cord injuries (SCIs) presents unique medical and economic challenges for practitioners. A retrospective chart review was conducted at 3 acute care hospitals in metropolitan Detroit for patients admitted with PrUs due to gunshot-SCIs between January 2004 and December 2008. Multivariate analysis using logistic regression was conducted to choose for the independent predictors of infected PrUs. Mean adjusted in-hospital costs per patient and per hospitalization were calculated and compared between infected and noninfected PrUs. The study cohort included 201 gunshot-SCI patients with PrUs contributing to 395 admissions, including readmissions, between 2004 and 2008. Seventy-six patients (38%) had infected PrUs at time of the index admission. Independent predictors of infected PrUs on index admission included Charlson Comorbidity Index ≥2 (odds ratio, 2.18, P = .026) and stage III/IV PrU (odds ratio, 4.82; P cost of $19,969 ± $6639 per patient. The mean adjusted cost per hospitalization for patients with infected PrUs was significantly higher than that for patients with noninfected PrUs ($16,735 ± $8310 vs $12,356 ± $7007; P costs.

Full Text Available This study aimed to determine the prevalence of infection related to the provisional catheter for hemodialysis in a teaching hospital and evaluate the risk factors associated with these infections.  A cross-sectional study analyzed by descriptive statistics and parametric tests. It was found that out of 129 patients, 48.8 % had catheter-related infection in hemodialysis, 65 % were male, 33.3 % were 60 years old and over, and 88 % of patients were admitted to intensive care unit. The prevalence of infection in this group was high, and the vast majority of diagnoses of infection were empirical. Given this, it is suggested to establish the routine culture of the catheter tip in all cases of suspected catheter infection to improve the quality of patient care, and the relentless pursuit of the causes that trigger the infection process in line with good practice from across the healthcare team.

Full Text Available Viruses that cause respiratory tract infections are the most common agents of infectious diseases in humans throughout the world. A virus that infects the respiratory system, may induce various clinical symptoms. What is more, the same symptoms may be caused by different viruses. The aim of the study was to analyze the prevalence of enteroviruses that cause respiratory infections in patients with influenzavirus A/H1N1 hospitalized in the Lublin province. The experimental material was throat and nose swabs taken from patients hospitalized in Lublin and Tomaszow Lubelski. In the group of 44 patients (20 women and 24 men infected with influenza A/H1N1, the genetic material of enteroviruses was detected in 13 patients (29.5%. Respiratory viruses co-infections are very common in hospitalized patients. Studies show that co-infection with influenza virus and enterovirus are more common in children than in adults. Moreover, viral respiratory tract infections are independent from the patients’ gender.

The spread of Extended Spectrum β-lactamases (ESBLs) among Enterobacteriaceae and other Gram-Negative pathogens in the community and hospitals represents a major challenge to combat infections. We conducted a study to assess the prevalence and genetic makeup of ESBL-type resistance in bacterial isolates causing community- and hospital-acquired urinary tract infections. A total of 172 isolates of Enterobacteriaceae were collected in Dar es Salaam, Tanzania, from patients who met criteria of community and hospital-acquired urinary tract infections. We used E-test ESBL strips to test for ESBL-phenotype and PCR and sequencing for detection of ESBL genes. Overall 23.8% (41/172) of all isolates were ESBL-producers. ESBL-producers were more frequently isolated from hospital-acquired infections (32%, 27/84 than from community-acquired infections (16%, 14/88, p Enterobacteriaceae causing both hospital- and community-acquired infections in Tanzania.

Waterless alcohol-based hand sanitizers are an increasingly popular method of hand hygiene and help prevent hospital-acquired infection (HAI). Whether hand sanitizer dispensers (HSDs) may themselves harbor pathogens or act as fomites has not been reported. All HSDs in the surgical intensive care unit of an urban teaching hospital were cultured at three sites: The dispenser lever, the rear underside, and the area surrounding the dispensing nozzle. All HSDs yielded one or more bacterial species, including commensal skin flora and enteric gram-negative bacilli. Colonization was greatest on the lever, where there is direct hand contact. Hand sanitizer dispensers can become contaminated with pathogens that cause HAI and thus are potential fomites.

According to WHO, Malaysia has been classified as a concentrated epidemic country due to progression of HIV infection in the population of injecting drug users. The main objectives of current study are to determine the prevalence of HBV among HIV-positive individuals in a tertiary care hospital of Malaysia and to assess the predictors involved in the outcomes of HIV-HBV co-infected patients. A retrospective, cross-sectional study is conducted at Hospital Palau Pinang, Malaysia. The collection of socio-demographic data as well as clinical data is done with the help of data collection form. Data were analyzed after putting the collected values of required data by using statistical software SPSS version 20.0 and P > 0.05 is considered as significant. Results show that the overall prevalence of HBV was 86 (13%) including 495 (74.5%) males and 169 (25.5%) females among a total of 664 HIV-infected patients. It was observed that there is a high prevalence of HIV-HBV co-infection in males 76 (11.4%) as compared to females 10 (1.5%) (P = 0.002). The median age of the study population was 39 years. The statistical significant risk factors involved in the outcomes of HIV-HBV co-infected patients were observed in the variables of gender, age groups, and injecting drug users. The findings of the present study shows that the prevalence of HBV infection among HIV-positive patients was 13% and the risk factors involved in the outcomes of HIV-HBV co-infected patients were gender, age, and intravenous drug users. © 2015 Wiley Periodicals, Inc.

Obesity is the most common public health problem and is a clinically complicating risk factor among hospitalized children. The impact of pediatric obesity on the severity and morbidity of lower respiratory tract infections remains unclear. We conducted a retrospective cohort study of bronchitis and pneumonia among children aged 2-20 years using hospital discharge records. The data were obtained from the Kid's Inpatient Database in 2003, 2006, 2009, and 2012, and were weighted to estimate the number of hospitalizations in the United States. We used the International Classification of Diseases, Ninth Revision, Clinical Modification code (278.0×) to classify whether the patient was obese or not. We investigated the associations between pediatric obesity and use of mechanical ventilation using multivariable logistic regression model. In addition, we ascertained the relationships between pediatric obesity, comorbid blood stream infections, mean healthcare cost, and length of hospital stay. We estimated a total of 133 602 hospitalizations with pneumonia and bronchitis among children aged between 2 and 20 years. Obesity was significantly associated with use of mechanical ventilation (adjusted OR 2.90, 95% CI 2.15-3.90), comorbid bacteremia or septicemia (adjusted OR 1.58, 95% CI 1.03-2.44), elevated healthcare costs (adjusted difference $383, 95%CI $276-$476), and prolonged length of hospital stay (difference 0.32 days, 95%CI 0.23-0.40 days), after adjusting for patient and hospital characteristics using multivariable logistic regression models. Pediatric obesity is an independent risk factor for severity and morbidity among pediatric patients with lower respiratory tract infections. These findings suggest the importance of obesity prevention for pediatric populations. © 2017 John Wiley & Sons Ltd.

Full Text Available Predictors of death in hospitalized HIV-infected patients have not been previously reported in Bangladesh.The primary aim of this study was to determine predictors of death among hospitalized HIV-infected patients at a large urban hospital in Bangladesh.A study was conducted in the HIV in-patient unit (Jagori Ward of icddr,b's Dhaka Hospital. Characteristics of patients who died during hospitalization were compared to those of patients discharged from the ward. Bivariate analysis was performed to determine associations between potential risk factors and death. Multivariable logistic regression was used to identify factors independently associated with death.Of 293 patients admitted to the Jagori Ward, 57 died during hospitalization. Most hospitalized patients (67% were male and the median age was 35 (interquartile range: 2-65 years. Overall, 153 (52% patients were diagnosed with HIV within 6 months of hospitalization. The most common presumptive opportunistic infections (OIs identified were tuberculosis (32%, oesophageal candidiasis (9%, Pneumocystis jirovecii pneumonia (PJP (8%, and histoplasmosis (7%. On multivariable analysis, independent predictors of mortality were CD4 count ≤200 cells/mm3 (adjusted odds ratio [aOR]: 16.6, 95% confidence interval [CI]: 3.7-74.4, PJP (aOR: 18.5, 95% CI: 4.68-73.3, oesophageal candidiasis (aOR: 27.5, 95% CI: 5.5-136.9, malignancy (aOR:15.2, 95% CI: 2.3-99.4, and bacteriuria (aOR:7.9, 95% CI: 1.2-50.5. Being on antiretroviral therapy prior to hospitalization (aOR: 0.2, 95% CI: 0.06-0.5 was associated with decreased mortality.This study showed that most patients who died during hospitalization on the Jagori Ward had HIV-related illnesses which could have been averted with earlier diagnosis of HIV and proper management of OIs. It is prudent to develop a national HIV screening programme to facilitate early identification of HIV.

Increasing rate of Diabetic Foot Infections (DFIs) caused by multi-drug-resistance pathogens plays a huge role in the duration of hospitalization, morbidity, and mortality of diabetic patients. The aim of the study is to assess the antibiotic sensitivity pattern of bacteria in DFIs and causative microorganisms. Using cross-sectional retrospective study, data were collected from medical records of DFIs patients previously hospitalized atHaji Adam Malik Hospital, Medan from January to July 2017. 33 patients met the criteria and got enrolled in the study. The classification of DFIs was evaluated according to Wagner’s Classification. Evaluation of antibiotic sensitivity and identification of causative microorganisms were performed in standard microbiologic methods. The most common grade of DFIs was Grade-4 (48.5%), followed by Grade-3 (39.4%) and Grade-5 (9.1%). A total of 12 pathogens were identified. The most common infecting microorganism isolated on pus cultures was Klebsiella pneumonia (33.3%), followed by Escherichia coli (24.2%), Acinetobacter baumanni (12.1%), and Staphylococcus aureus (9.1%). Frequent susceptible antibiotics were Amikacin (88.8%), Imipenem (87%), Meropenem (84.6%), Erythromycin (75%), and Cefoperazone/Sulbactam (68.9%).

Full Text Available BACKGROUND AND METHODOLOGY: Due to geographic overlap of malaria and visceral leishmaniasis (VL, co-infections may exist but have been poorly investigated. To describe prevalence, features and risk factors for VL-malaria co-infections, a case-control analysis was conducted on data collected at Amudat Hospital, Uganda (2000-2006 by Médecins sans Frontières. Cases were identified as patients with laboratory-confirmed VL and malaria at hospital admission or during hospitalization; controls were VL patients with negative malaria smears. A logistic regression analysis was performed to study the association between patients' characteristics and the occurrence of the co-infection. RESULTS: Of 2414 patients with confirmed VL, 450 (19% were positively diagnosed with concomitant malaria. Most co-infected patients were males, residing in Kenya (69%. While young age was identified by multivariate analysis as a risk factor for concurrent VL and malaria, particularly the age groups 0-4 (odds ratio (OR: 2.44; 95% confidence interval (CI: 1.52-3.92 and 5-9 years (OR: 2.23, 95% CI: 1.45-3-45, mild (OR: 0.53; 95% CI: 0.32-0.88 and moderate (OR: 0.45; 95% CI: 0.27-0.77 anemia negatively correlated with the co-morbidity. VL patients harboring skin infections were nearly three times less likely to have the co-infection (OR: 0.35; 95% CI: 0.17-0.72, as highlighted by the multivariate model. Anorexia was slightly more frequent among co-infected patients (OR: 1.71; 95% CI: 0.96-3.03. The in-hospital case-fatality rate did not significantly differ between cases and controls, being 2.7% and 3.1% respectively (OR: 0.87; 95% CI: 0.46-1.63. CONCLUSIONS: Concurrent malaria represents a common condition among young VL patients living in the Pokot region of Kenya and Uganda. Although these co-morbidities did not result in a poorer prognosis, possibly due to early detection of malaria, a positive trend towards more severe symptoms was identified, indicating that routine

Public reporting of surgical site infections (SSIs) by hospitals is largely limited to infections detected during surgical hospitalizations or readmissions to the same facility. SSI rates may be underestimated if patients with SSIs are readmitted to other hospitals. We assessed the impact of readmissions to other facilities on hospitals' SSI rates following primary total hip arthroplasty (THA) or total knee arthroplasty (TKA). This was a retrospective cohort study of all patients who underwent primary THA or TKA at California hospitals between 1 January 2006 and 31 December 2009. SSIs were identified using ICD-9-CM diagnosis codes predictive of SSI assigned at any California hospital within 365 days of surgery using a statewide repository of hospital data that allowed tracking of patients between facilities. We used statewide data to estimate the fraction of each hospital's THA and TKA SSIs identified at the operative hospital versus other hospitals. A total of 91 121 THA and 121 640 TKA procedures were identified. Based on diagnosis codes, SSIs developed following 2214 (2.3%) THAs and 2465 (2.0%) TKAs. Seventeen percent of SSIs would have been missed by operative hospital surveillance alone. The proportion of hospitals' SSIs detected at nonoperative hospitals ranged from 0% to 100%. Including SSIs detected at nonoperative hospitals resulted in better relative ranking for 61% of THA hospitals and 61% of TKA hospitals. Limiting SSI surveillance to the operative hospital caused varying degrees of SSI underestimation and substantially impacted hospitals' relative rankings, suggesting that alternative methods for comprehensive postdischarge surveillance are needed for accurate benchmarking.

Water is the main stimulus for the development of microorganisms, and its flow has an important role in the spreading of contaminants. In hospitals, the water distribution system requires special attention since it can be a source of pathogens, including those in the form of biofilms often correlated with resistance of microorganisms to various treatments. In this paper, information relevant to cases of nosocomial infections involving water circuits as a source of contaminants is compiled, with emphasis on the importance of microbiological control strategies to prevent the installation, spreading and growth of microorganisms in hospitals. An overview of the worldwide situation is provided, with emphasis on Brazilian hospitals. Different approaches normally used to control the occurrence of nosocomial infections due to waterborne contaminants are analyzed, and the use of the polysaccharide chitosan for this specific application is briefly discussed.

Full Text Available Abstract Background: Lower respiratory tract infections like acute bronchitis, exacerbated chronic obstructive pulmonary disease and community-acquired pneumonia are often unnecessarily treated with antibiotics, mainly because of physicians' difficulties to distinguish viral from bacterial cause and to estimate disease-severity. The goal of this trial is to compare medical outcomes, use of antibiotics and hospital resources in a strategy based on enforced evidence-based guidelines versus procalcitonin guided antibiotic therapy in patients with lower respiratory tract infections. Methods and design: We describe a prospective randomized controlled non-inferiority trial with an open intervention. We aim to randomize over a fixed recruitment period of 18 months a minimal number of 1002 patients from 6 hospitals in Switzerland. Patients must be >18 years of age with a lower respiratory tract infections Discussion: Use of and prolonged exposure to antibiotics in lower respiratory tract infections is high. The proposed trial investigates whether procalcitonin-guidance may safely reduce antibiotic consumption along with reductions in hospitalization costs and antibiotic resistance. It will additionally generate insights for improved prognostic assessment of patients with lower respiratory tract infections. Trial registration: ISRCTN95122877

An update on opportunistic infections/co-infections (OIs/CIs) is essential to understand the success of highly active antiretroviral therapy offered by the government agencies in reducing AIDS-related OIs/CIs. Hence, the present study aimed to evaluate the frequency of OIs/CIs in HIV-positive individuals at a tertiary care hospital in Mumbai. Its' association with CD4 counts, anti-retroviral treatment and on HIV transmission was also determined. An observational study was designed to evaluate different OIs/CIs in individuals, who tested positive for HIV infection at the ICTC/Shakti Clinic of Seth G.S. Medical College and KEM Hospital, Mumbai. Data analysis was done with the use of SPSS software (version 19.0, SPSS, Chicago, IL, USA). P value was considered significant if it is < 0.05. Heterosexual contact was the major route of transmission among the enrolled 185 individuals. Ninety (48.06%) HIV-infected individuals were with OIs/CIs. Tuberculosis (TB) was the most common OI (68.8%). Other CIs noted were Herpes zoster, syphilis, hepatitis C and B, malaria, typhoid and dengue. The median CD4 count in HIV-positive individuals with TB was 337 ± 248 cells/μl, and 67.7% of individuals with OIs/CIs had low CD4 counts (<400 cells/μl). Individuals in 31-40 years of age group had significantly (P = 0.01) more OIs/CIs. More (53.7%) spouse/children of HIV-positive individuals without OIs/CIs were HIV-1 positive. Low proportions of individuals with or without OIs/CIs were on ART. Nearly half of HIV-infected individuals were with OIs/CIs. Initiation of free ART programme since 2004 possibly associated with the type and rate of OIs/CIs. Tuberculosis and multiple OIs/CIs were associated with low CD4 counts. Infection was high in 31-40 years age group. Most of the spouses of individuals without OIs/CIs were HIV positive, indirectly indicates lack of condom use or lack of awareness of condom use.

Full Text Available BACKGROUND: Hospital-acquired infections (HAI are associated with increased attributable morbidity, mortality, prolonged hospitalization, and economic costs. A simple, reliable prediction model for HAI has great clinical relevance. The objective of this study is to develop a scoring system to predict HAI that was derived from Logistic Regression (LR and validated by Artificial Neural Networks (ANN simultaneously. METHODOLOGY/PRINCIPAL FINDINGS: A total of 476 patients from all the 806 HAI inpatients were included for the study between 2004 and 2005. A sample of 1,376 non-HAI inpatients was randomly drawn from all the admitted patients in the same period of time as the control group. External validation of 2,500 patients was abstracted from another academic teaching center. Sixteen variables were extracted from the Electronic Health Records (EHR and fed into ANN and LR models. With stepwise selection, the following seven variables were identified by LR models as statistically significant: Foley catheterization, central venous catheterization, arterial line, nasogastric tube, hemodialysis, stress ulcer prophylaxes and systemic glucocorticosteroids. Both ANN and LR models displayed excellent discrimination (area under the receiver operating characteristic curve [AUC]: 0.964 versus 0.969, p = 0.507 to identify infection in internal validation. During external validation, high AUC was obtained from both models (AUC: 0.850 versus 0.870, p = 0.447. The scoring system also performed extremely well in the internal (AUC: 0.965 and external (AUC: 0.871 validations. CONCLUSIONS: We developed a scoring system to predict HAI with simple parameters validated with ANN and LR models. Armed with this scoring system, infectious disease specialists can more efficiently identify patients at high risk for HAI during hospitalization. Further, using parameters either by observation of medical devices used or data obtained from EHR also provided good prediction

The emergence of the epidemic Clostridium difficile 027 strain has renewed interest in infection control practices. To review the effectiveness of different practices to reduce hospital C. difficile infection (CDI) in non-outbreak settings. Data sources were identified by a MEDLINE search in English and French. The ORION statement was used to extract key data from articles describing interventions to manage CDI. Twenty-one studies, published between 1982 and December 2013, were reviewed. Most studies were before-after interventions, and a few studies were planned, formal, prospective investigations. The effects of the following single or combined interventions were described: antibiotic management; environmental disinfection and/or cleaning; hand hygiene; bathing; surveillance; cohorting; and isolation of infected patients in private rooms. With many methodological weaknesses and some inadequate research reporting, the observed reduction in CDI may not be entirely attributable to interventions. Although infection control programmes involving education and handwashing/gloving protocols were found to have contributed to a reduction in the incidence of CDI, these measures were usually a component of multi-faceted interventions that did not provide for evaluation of the relative impact of each factor. Appropriate environmental disinfection and antibiotic stewardship would appear to offer the most effective benefits. Copyright © 2015 The Healthcare Infection Society. Published by Elsevier Ltd.

Full Text Available Invasive infections caused by Candida spp. are an important problem in immunocompromised patients. There is scarce data on the epidemiology of blood stream candidiasis in Salvador, Brazil. This study evaluates the risk factors associated with candidemia, among patients admitted to three tertiary, private hospitals, in Salvador, Brazil. We conducted a case-control, retrospective study to compare patients with diagnosis of candidemia in three different tertiary hospitals in Salvador, Brazil. Patients were matched for nosocomial, acquired infections, according to the causal agent: cases were defined by positive blood cultures for Candida species. Controls were those patients who had a diagnosis of systemic bacterial infection, with a positive blood culture to any bacteria, within the same time period (± 30 days of case identification. The groups were compared for the main known risk factors for candidemia and for mortality rates. A hundred thirty-eight patients were identified. Among the 69 cases, only 14 were diagnosed as infected by Candida albicans. Candida species were defined in only eight cultures: C. tropicalis (4 cases, C. glabrata, C. parapsilosis, C. guillermondi, C. formata (1 case each. The main risk factors, identified in a univariate analysis, were: presence of a central venous catheter (CVC, use of parenteral nutrition support (PNS, previous exposure to antibiotics, and chronic renal failure (CRF. No association was detected with surgical procedures, diabetes mellitus, neutropenia or malignancies. Patients were more likely to die during the hospitalization period, but the rates of death caused by the infections were similar for cases and controls. The length of hospitalization was similar for both groups, as well as the time for a positive blood culture. Blood stream infection by Candida spp. is associated with CVC, PNS, previous use of antibiotics, and CRF. The higher mortality rate for cases probably better reflects the severity

Full Text Available Context: Acinetobacter infections are a major nosocomial infection causing epidemics of infection in the Intensive Care Units (ICU. Aims: This study estimates the clinical and economic outcomes of Acinetobacter infections and compares them with those of non-Acinetobacter bacterial infections. Settings and Design: Prospective cross-sectional observational study carried out for 6 months in the medicine ICU of a tertiary care hospital. Materials and Methods: Patients were divided in two groups, one group with Acinetobacter infections and the other with non-Acinetobacter infections. The data was collected for infection, length of stay (LOS, mortality and cost along with patient demographics from the hospital records for analysis. Statistical Analysis Used: The data was analyzed using Statistical Package for the Social Sciences Version 15.0. The LOS and cost of treatment (COT for the two groups were compared using the nonparametric Mann–Whitney U-test. Results: A total of 220 patients were studied out of which 91 had Acinetobacter infections. The median LOS was 20 days in Group-A and 12 days in Group-B (P < 0.0001. The median COT was INR 125,862 in Group-A and INR 68,228 in the Group-B (P < 0.0001. Mortality in Group-A and Group-B was 32.97 and 32.56 (P = 0.949 respectively. Conclusion: The burden of Acinetobacter infections in ICUs is increasing with the increase in LOS and COT for the patients. The infection control team has to play a major role in reducing the rate of nosocomial infections.

Document seasonality occurrence and epidemiologic characteristics of Cyclospora cayetanensis infections during a 10-year period from patients consulting at the University Hospital, Honduras. Retrospective non interventional hospital-based study analyzed laboratory results from the period 2002 to 2011 of fresh and Ziehl-Nielsen carbolfuchsin stained routine stool samples received for parasitologic examination. Sporadically a sample with numerous oocysts was allowed to sporulate in 2.5 % potassium dichromate confirming the presence of bi-cystic bi-zoic oocysts. A total of 35,157 fecal samples were examined during a ten-year span, of which a third (28.4 %) was stained by the Ziehl-Neelsen carbolfuchsin method diagnosing a total of 125 (1.3 %) C.cayetanensis infections. A statistically significant apparent seasonality was observed most years during May to August (range p < 0.036-0.001), with 83.3 % of 125 cases occurring in those rainy months. All C. cayetanensis cases came from urban poor neighborhoods; male/female relation was 1:1 except in 2006, when all patients were females (p = 0.05; r(2) = 22,448). Forty four point eight percent of the stool samples were diarrheic or liquid and 65.6 % infections were identified in children 10 years old or less. Enteric helminths and protozoa co-infected Cyclospora positive patients in 52 instances.: 8 % Ascaris lumbricoides, 8 % Giardia duodenalis, 23.2 % Blastocystis spp. and less frequently Entamoeba histolytica/E. dispar, Strongyloides stercoralis, and Trichuris trichiura. Results suggest a seasonal pattern for Cyclospora infections diagnosed in a clinical setting during the rainy months in Tegucigalpa and surrounding areas. Community studies should be conducted to support or dispute these observations.

During the Severe Acute Respiratory Syndrome (SARS) outbreak, high compliance in healthcare workers to hand hygiene was primarily driven by fear. However, the post-SARS period confirmed that this practice was not sustainable. At the Singapore General Hospital, a 1,600-bedded acute tertiary care hospital, the hand hygiene program was revised in early 2007 following Singapore's signing of the pledge to the World Health Organization (WHO) "Clean Care is Safer Care" program. A multi-prong approach was used in designing the hand hygiene program. This included system change; training and education; evaluation and feedback; reminders in the workplace; and institutional safety climate. Hand hygiene compliance rate improved from 20% (in January 2007) to 61% (2010). Improvement was also seen annually in the compliance to each of the 5 moments as well as in all staff categories. Healthcare-associated MRSA infections were reduced from 0.6 (2007) to 0.3 (2010) per 1000 patient-days. Leadership's support of the program evidenced through visible leadership presence, messaging and release of resources is the key factor in helping to make the program a true success. The hospital was recognised as a Global Hand Hygiene Expert Centre in January 2011. The WHO multi-prong interventions work in improving compliance and reducing healthcare associated infections.

Acute upper and lower respiratory infections are main causes of mortality and morbidity in children. Air pollution has been recognized as an important contributor to development and exacerbation of respiratory infections. However, few studies are available in China. In this study, we investigated the short-term effect of air pollution on hospital visits for acute upper and lower respiratory infections among children under 15 years in Ningbo, China. Poisson generalized models were used to estimate the associations between air pollution and hospital visits for acute upper and lower respiratory infections adjusted for temporal, seasonal, and meteorological effects. We found that four pollutants (PM 2.5 , PM 10 , NO 2 , and SO 2 ) were significantly associated with hospital visits for acute upper and lower respiratory infections. The effect estimates for acute upper respiratory infections tended to be higher (PM 2.5 ER = 3.46, 95% CI 2.18, 4.76; PM 10 ER = 2.81, 95% CI 1.93, 3.69; NO 2 ER = 11.27, 95% CI 8.70, 13.89; SO 2 ER = 15.17, 95% CI 11.29, 19.19). Significant associations for gaseous pollutants (NO 2 and SO 2 ) were observed after adjustment for particular matter. Stronger associations were observed among older children and in the cold period. Our study suggested that short-term exposure to outdoor air pollution was associated with hospital visits for acute upper and lower respiratory infections in Ningbo.

Malaria and HIV/AIDS are two of the most widespread infectious diseases encountered in sub-Saharan Africa. Even minor interactions between these two diseases could have substantial effects on public health. The purpose of this study was to investigate associations between malaria and HIV infection. Study was carried out over an 8-month period (April 1, 2003 to November 30, 2003) in the Tropical and Infectious Diseases Department of the Donka National Hospital in Conakry, Guinea. A total of 89 malaria patients including 41 cases with HIV infection and 48 controls without HIV infection were included. All patients were hospitalized during the study and provided informed consent. Results showed that malaria affected all age groups in the same proportion. Mean patient age was 34 years (range, 15 and 76 years). Males were more frequently infected with a sex ratio of 1.05. The average number of malaria episodes was higher in cases (malaria with HIV-infection than in controls (malaria without HIV infection). Hyperthermia was observed in most cases (68.29%) and controls (77.08%). Severe anemia was observed in 26.82% of cases versus 10.41% of controls. Low parasite density was observed in 73.17% of cases as compared to 68.75% of controls. The recovery rate was higher in the control group than in case group: 27.08% versus 14.63%. The death rate was higher in the case group than in the control group: 21.95% versus 6.25%. These findings demonstrate a link between malaria and HIV. The frequency of malaria episodes was higher in patients with HIV infection than patients without HIV infection and the outcome of malarial episodes was better in patients without HIV infection.

In hospital care, management of the risk of infection represents a crucial issue. Nevertheless, this question remains a neglected area in anthropological research, especially in African countries. To shed new light on this question, we conducted an anthropological investigation in the infectious disease department of a hospital in Niger. Daily observation of the work of the hospital staff for a total period of 6 months was spread out over 2008 and 2009. During our prolonged stay, we also collected 64 in-depth interviews of health care workers and attendants in the department. This study method made it possible to describe many of the practices and discourses related to the issues of medical and personal care and hospital hygiene and to compare the practices observed to standard principles for preventing hospital-acquired infections. Our ethnographic attention to the behavior of the actors showed the absence of formal spatial segmentations between different activities. The care provided by the untrained relatives serving as personal attendants introduced territorial enclaves governed by home hygiene standards into the interior of technical spaces. At the same time, privatizing equipment and space for their diverse activities, the medical staff disrupted technical chains and generated the recurrent crossing of microbial geographies. These results allow us to offer two principal guidelines for improving the quality of care and the management of risks of infection in hospitals in West Africa: (1) the essential role of the attendants in the care provided to hospital inpatients must be officially taken into account, especially by including them in the organization of medical hygiene procedures; (2) the different overlapping technical activities and social activities in the work space must be limited by their geographic and architectural segmentation.

Full Text Available Abstract Background Surgical site infections (SSI remain a major clinical problem in terms of morbidity, mortality, and hospital costs. Nearly 60% of SSI diagnosis occur in the postdischarge period. However, literature provides little information on risk factors associated to in-hospital and postdischarge SSI occurrence. A national prospective multicenter study was conducted with the aim of assessing the incidence of both in-hospital and postdisharge SSI, and the associated risk factors. Methods In 2002, a one-month, prospective national multicenter surveillance study was conducted in General and Gynecological units of 48 Italian hospitals. Case ascertainment of SSI was carried out using standardized surveillance methodology. To assess potential risk factors for SSI we used a conditional logistic regression model. We also reported the odds ratios of in-hospital and postdischarge SSI. Results SSI occurred in 241 (5.2% of 4,665 patients, of which 148 (61.4% during in-hospital, and 93 (38.6% during postdischarge period. Of 93 postdischarge SSI, sixty-two (66.7% and 31 (33.3% were detected through telephone interview and questionnaire survey, respectively. Higher SSI incidence rates were observed in colon surgery (18.9%, gastric surgery (13.6%, and appendectomy (8.6%. If considering risk factors for SSI, at multivariate analysis we found that emergency interventions, NNIS risk score, pre-operative hospital stay, and use of drains were significantly associated with SSI occurrence. Moreover, risk factors for total SSI were also associated to in-hospital SSI. Additionally, only NNIS, pre-operative hospital stay, use of drains, and antibiotic prophylaxis were associated with postdischarge SSI. Conclusion Our study provided information on risk factors for SSI in a large population in general surgery setting in Italy. Standardized postdischarge surveillance detected 38.6% of all SSI. We also compared risk factors for in-hospital and postdischarge SSI

Full Text Available Background and Objective: The hospital-acquired infection (HAI is defined as a serious public health problem, resulting in increased morbidity and mortality. The role of nursing staff on this issue is essential in ensuring solving and quality care, minimizing damages that may arise as a result of the care offered to patients. From this discussion, this study aimed to understand the vision of the nursing team professionals about HAI. Method: This is a qualitative, descriptive study. The data collection was performed using a semi-structured interview. We used the Bardin Content Analysis. Results: The categories that emerged were: Definition of HAI; Implemented prevention measures; Difficulties in controlling the HAI, and coping strategies. The study found a clear understanding of what is a HAI for nurses, however, for practical nurses that understanding appeared wrongly. Hand washing and the use of PPE were the main measures mentioned in prevention. The low uptake of the above measures and the problems of working in teams were listed challenges. Conclusion: Therefore, lifelong learning is an important instrument to promote changes in practice. It is essential that HIC act with professionals raising their awareness about the importance of play in the prevention and control of potential complications, ensuring the safety and quality of care directed to the patient.

Healthcare-associated infections have serious implications for both patients and hospitals. Environmental surface contamination is the key to transmission of nosocomial pathogens. Routine manual cleaning and disinfection eliminates visible soil and reduces environmental bioburden and risk of transmission, but may not address some surface contamination. Automated area decontamination technologies achieve more consistent and pervasive disinfection than manual methods, but it is challenging to demonstrate their efficacy within a randomized trial of the multiple interventions required to reduce healthcare-associated infection rates. Until data from multicenter observational studies are available, automated area decontamination technologies should be an adjunct to manual cleaning and disinfection within a total, multi-layered system and risk-based approach designed to control environmental pathogens and promote patient safety.

The aim of this study was to evaluate clinical and radiological findings and the role of periapical infection and antecedent dental treatment of infected focus teeth in odontogenic maxillofacial abscesses requiring hospital care. In this retrospective cohort study, we evaluated medical records and panoramic radiographs during the hospital stay of patients (n = 60) admitted due to odontogenic maxillofacial infection originating from periapical periodontitis. Twenty-three (38 %) patients had received endodontic treatment and ten (17 %) other acute dental treatment. Twenty-seven (45 %) had not visited the dentist in the near past. Median age of the patients was 45 (range 20-88) years and 60 % were males. Unfinished root canal treatment (RCT) was the major risk factor for hospitalisation in 16 (27 %) of the 60 cases (p = .0065). Completed RCT was the source only in 7 (12 %) of the 60 cases. Two of these RCTs were adequate and five inadequate. The initiation of inadequate or incomplete primary RCT of acute periapical periodontitis appears to open a risk window for locally invasive spread of infection with local abscess formation and systemic symptoms. Thereafter, the quality of the completed RCT appears to have minor impact. However, a considerable proportion of the patients had not received any dental treatment confirming the importance of good dental health. Thus, thorough canal debridement during the first session is essential for minimising the risk for spread of infection in addition to incision and drainage of the abscess. If this cannot be achieved, tooth extraction should be considered. Incomplete or inadequate canal debridement and drainage of the abscess may increase the risk for spread of endodontic infection.

Ophthalmic infections cause significant morbidity in Cambodian children but aetiologic data are scarce. We investigated the causes of acute eye infections in 54 children presenting to the ophthalmology clinic at Angkor Hospital for Children, Siem Reap between March and October 2012. The median age at presentation was 3.6 years (range 6 days - 16.0 years). Forty two patients (77.8%) were classified as having an external eye infection, ten (18.5%) as ophthalmia neonatorum, and two (3.7%) as intra-ocular infection. Organisms were identified in all ophthalmia neonatorum patients and 85.7% of patients with an external eye infection. Pathogens were not detected in either of the intra-ocular infection patients. Most commonly isolated bacteria were Staphylococcus aureus (23 isolates), coagulase-negative staphylococci (13), coliforms (7), Haemophilus influenzae/parainfluenzae (6), Streptococcus pneumoniae (4), and Neisseria gonorrhoeae (2). Chlamydia trachomatis DNA was detected in 60% of swabs taken from ophthalmia neonatorum cases. This small study demonstrates the wide range of pathogens associated with common eye infections in Cambodian children. The inclusion of molecular assays improved the spectrum of detectable pathogens, most notably in neonates.

Variation in Clostridium difficile infection (CDI) rates between healthcare institutions suggests overall incidence could be reduced if the lowest rates could be achieved more widely. We used whole-genome sequencing (WGS) of consecutive C. difficile isolates from 6 English hospitals over 1 year (2013-14) to compare infection control performance. Fecal samples with a positive initial screen for C. difficile were sequenced. Within each hospital, we estimated the proportion of cases plausibly acquired from previous cases. Overall, 851/971 (87.6%) sequenced samples contained toxin genes, and 451 (46.4%) were fecal-toxin-positive. Of 652 potentially toxigenic isolates >90-days after the study started, 128 (20%, 95% confidence interval [CI] 17-23%) were genetically linked (within ≤2 single nucleotide polymorphisms) to a prior patient's isolate from the previous 90 days. Hospital 2 had the fewest linked isolates, 7/105 (7%, 3-13%), hospital 1, 9/70 (13%, 6-23%), and hospitals 3-6 had similar proportions of linked isolates (22-26%) (P ≤ .002 comparing hospital-2 vs 3-6). Results were similar adjusting for locally circulating ribotypes. Adjusting for hospital, ribotype-027 had the highest proportion of linked isolates (57%, 95% CI 29-81%). Fecal-toxin-positive and toxin-negative patients were similarly likely to be a potential transmission donor, OR = 1.01 (0.68-1.49). There was no association between the estimated proportion of linked cases and testing rates. WGS can be used as a novel surveillance tool to identify varying rates of C. difficile transmission between institutions and therefore to allow targeted efforts to reduce CDI incidence. © The Author 2017.

Full Text Available PURPOSE: Urinary tract infection is the most common nosocomially acquired infection. It is important to know the etiology and antibiotic susceptibility infectious agents to guide the initial empirical treatment. OBJECTIVE: To determine the prevalence of bacterial strains and their antibiotic susceptibility in nosocomially acquired urinary tract infection in a university hospital between January and June 2003. METHODS: We analyzed the data of 188 patients with positive urine culture (= 10(5 colony-forming units/mL following a period of 48 hours after admission. RESULTS: Half of patients were male. Mean age was 50.26 ± 22.7 (SD, range 3 months to 88 years. Gram-negative bacteria were the agent in approximately 80% of cases. The most common pathogens were E. coli (26%, Klebsiella sp. (15%, P. aeruginosa (15% and Enterococcus sp. (11%. The overall bacteria susceptibility showed that the pathogens were more sensible to imipenem (83%, second or third generation cephalosporin and aminoglycosides; and were highly resistant to ampicillin (27% and cefalothin (30%. It is important to note the low susceptibility to ciprofloxacin (42% and norfloxacin (43%. CONCLUSION: This study suggests that if one can not wait the results of urine culture, the best choices to begin empiric treatment are imipenem, second or third generation cephalosporin and aminoglycosides. Cefalothin and ampicillin are quite ineffective to treat these infections.

Full Text Available Objective: Survey the prevalence of arbovirus infections among pregnant women provided with care at a maternity hospital school in Recife, Pernambuco, Brazil. Method: Descriptive, cross-sectional, retrospective, and quantitative study, carried out with data collected from the notification forms filled in during obstetric screening between August 2015 and July 2016. Results: Positive serology was found for arboviruses in 40.2% of the 103 suspected cases. Serology was not performed or it showed inconclusive results in 59.8% of the cases. Dengue fever occurred in 44% of the cases, chikungunya in 34%, and zika fever in 22%. Infections were more frequent among pregnant women over 20 years old, with low income and low schooling levels, living in Recife (48.5% and Olinda, Pernambuco, Brazil (24.3%. The most frequently mentioned symptoms were arthralgia (94%, exanthema (82%, and fever (78%. Infections occurred within the first trimester of pregnancy (54.5%, 63.3% of the pregnant women had to be hospitalized, and 45.4% of them did not undergo morphological ultrasonography. Most babies were born full-term and they had adequate weight. The prevalence of microcephaly was 9.7% when considering cases of arbovirose and 62.5% when considering specific cases of zika fever. Conclusion: The prevalence and repercussions of arboviruses justify the consolidation of actions to fight Aedes aegypti, as well as the effective deployment of clinical protocols and recommendations aimed at the mother and child care.

OBJECTIVE To describe the hospital stays of patients with Clostridium difficile infection (CDI) and to measure the hospitalization costs of CDI (as primary and secondary diagnoses) from the French national health insurance perspective DESIGN Burden of illness study SETTING All acute-care hospitals in France METHODS Data were extracted from the French national hospitalization database (PMSI) for patients covered by the national health insurance scheme in 2014. Hospitalizations were selected using the International Classification of Diseases, 10 th revision (ICD-10) code for CDI. Hospital stays with CDI as the primary diagnosis or the secondary diagnosis (comorbidity) were studied for the following parameters: patient sociodemographic characteristics, mortality, length of stay (LOS), and related costs. A retrospective case-control analysis was performed on stays with CDI as the secondary diagnosis to assess the impact of CDI on the LOS and costs. RESULTS Overall, 5,834 hospital stays with CDI as the primary diagnosis were included in this study. The total national insurance costs were €30.7 million (US $33,677,439), and the mean cost per hospital stay was €5,267±€3,645 (US $5,777±$3,998). In total, 10,265 stays were reported with CDI as the secondary diagnosis. The total national insurance additional costs attributable to CDI were estimated to be €85 million (US $93,243,725), and the mean additional cost attributable to CDI per hospital stay was €8,295±€17,163, median, €4,797 (US $9,099±$8,827; median, $5,262). CONCLUSION CDI has a high clinical and economic burden in the hospital, and it represents a major cost for national health insurance. When detected as a comorbidity, CDI was significantly associated with increased LOS and economic burden. Preventive approaches should be implemented to avoid CDIs.

There is scarcity of data regarding epidemiology and clinical aspects of human adenovirus acute respiratory infection (ARI) among children in developing countries. Retrospective data on demographics, clinical presentation, outcomes and laboratory findings of 116 children admitted into Tuanku Jaafar Hospital in Seremban, Malaysia from 2012 to 2013 with documented diagnosis of community-acquired adenovirus ARI were collected and analyzed. Male to female ratio was 1.70. Median age was 14 (1-107) months. The commonest symptoms were fever (94.8%; 110/116), cough (82.8%, 96), rhinorrhea (63.8%; 74), interrupted feeding (66.4%; 77), diarrhea (33.6%; 39) and conjunctivitis (21.6%; 25). Mean temperature on admission was 38.4°C±0.9°C. Among all 116 subjects, 20.7% (24) needed oxygen supplementation, 57.8% (67) required intravenous hydration, 11.2% (13) were admitted into the pediatric intensive care unit and 6.9% (8) required mechanical ventilation. Only 1% (1/87) had positive blood culture (Streptococcus pneumoniae) among 87 who received antibiotic treatment. Case fatality rate was 2.6% (3/116) and 1.7% (2/116) developed bronchiolitis obliterans. Median length of hospital stay was 4 (1-50) days. Adenovirus ARI caused significant morbidity and substantial resource utilization among hospitalized Malaysian children. It should be considered in the differential diagnosis of infants below two years presenting with ARI associated with high fever. Antibiotics should not be prescribed as secondary bacterial infections are uncommon. © The Author 2015.

Full Text Available Vancomycin resistant Enterococcus faecium (VREF ia an emerging and challenging nosocomial pathogen. This study aimed to determine the prevalence, risk factors and clonal relationships between different VREF isolates in the intensive care units (ICUs of the university hospitals in our geographic location. This prospective study was conducted from July, 2012 until September, 2013 on 781 patients who were admitted to the ICUs of the Mansoura University Hospitals (MUHs, and fulfilled the healthcare-associated infection (HAI criteria. Susceptibility testing was determined using the disk diffusion method. The clonal relationships were evaluated with pulsed field gel electrophoresis (PFGE. Out of 52 E. faecium isolates, 12 (23.1% were vancomycin resistant. The significant risk factors for the VREF infections were: transfer to the ICU from a ward, renal failure, an extended ICU stay and use of third-generation cephalosporins, gentamicin, or ciprofloxacin. PFGE with the 12 isolates showed 9 different patterns; 3 belonged to the same pulsotype and another 2 carried a second pulsotypes. The similar pulsotypes isolates were isolated from ICUs of one hospital (EICUs; however, all of the isolates from the other ICUs had different patterns. Infection control policy, in conjunction with antibiotic stewardship, is important to combat VREF transmission in these high-risk patients.

Despite control efforts, the burden of health-care-associated infections in Europe is high and leads to around 37,000 deaths each year. We did a systematic review to identify crucial elements for the organisation of effective infection-prevention programmes in hospitals and key components for implementation of monitoring. 92 studies published from 1996 to 2012 were assessed and ten key components identified: organisation of infection control at the hospital level; bed occupancy, staffing, workload, and employment of pool or agency nurses; availability of and ease of access to materials and equipment and optimum ergonomics; appropriate use of guidelines; education and training; auditing; surveillance and feedback; multimodal and multidisciplinary prevention programmes that include behavioural change; engagement of champions; and positive organisational culture. These components comprise manageable and widely applicable ways to reduce health-care-associated infections and improve patients' safety. Copyright © 2015 Elsevier Ltd. All rights reserved.

Methicillin-resistant Staphylococcus aureus (MRSA) presents nosocomial infection problemsin hospitals. Identification of risk factors related to MRSA infection is a concern among healthcare provider. A retrospective case-control study was conducted to identify MRSA infection proportion among isolates, also to identify risk factors amonginpatients at Prof. dr.R. D. Kandou General Hospital, Manado. Data were from themedical record, from patient’s culture isolateswith positive Staphylococcus aureus infection from January-December 2015. Case subject isolated cultures of MRSA and control subject isolated cultures of non-MRSA. Bivariate analysis were performed in 10 independent variables (age, length of stay, prior use of antibiotics before cultures, history of HIV infection, prior use of corticosteroid, history of malignancy, history of chronic disease, prior use of medical tools (catheter, ventilator, etc), history of invasive medical procedure, history of hospitalization before). All variables with a p-value<0.05 were into multivariate analysis with forwarding stepwise logistic regression. Mean subjects age were 48.13 ± 2.05 years old and length of stay were 8.65 ± 0.25 days, and only prior antibiotic use-variable were considered statistically significant (p = 0.017; OR 1.889; 95%CI 1.595 – 2.238).

Despite hospitals' efforts to reduce health care-associated infections (HAIs), success rates vary. We studied how leadership practices might impact these efforts. We conducted eight case studies at hospitals pursuing central line-associated blood stream infection (CLABSI)-prevention initiatives. At each hospital, we interviewed senior leaders, clinical leaders, and line clinicians (n = 194) using a semistructured interview protocol. All interviews were transcribed and iteratively analyzed. We found that the presence of local clinical champions was perceived across organizations and interviewees as a key factor contributing to HAI-prevention efforts, with champions playing important roles as coordinators, cheerleaders, and advocates for the initiatives. Top-level support was also critical, with elements such as visibility, commitment, and clear expectations valued across interviewees. VALUE/ORGINALITY: Results suggest that leadership plays an important role in the successful implementation of HAI-prevention interventions. Improving our understanding of nonclinical differences across health systems may contribute to efforts to eliminate HAIs.

More than three decades after recognition of acquired immunodeficiency syndrome (AIDS) in the United States, the pandemic of human immunodeficiency virus (HIV) infection has dramatically changed the global burden of disease. The main goal of this research is retrospective analysis of epidemiological and clinical characteristics of 28 HIV infected patients, who were diagnosed and treated at the Clinic for Infectious Diseases in University Clinical Center Tuzla in the period from 1996 until the end of 2013. Retrospective analysis was performed using the medical records of 28 HIV-infected persons. Two rapid tests were used for HIV testing: OraQuick Advance test, Vikia HIV1/2, Elisa combo test, HIV RNA test. AIDS disease was determined by using the criteria from WHO. Among a total of 28 HIV-infected persons, 23 (82.14%) were males and 5 (17.86%) were females, with the male: female ratio of 4,6:1. In terms of the transmission route, a large proportion of cases were infected through heterosexual contact 19 (67.86%). At the time of the first visit, 16 (57.15%) patients showed asymptomatic HIV infection, 4 (14.28%) HIV infection with symptoms other than the AIDS defining diseases, and 8 (28.57) had AIDS. At the time of first hospital visit, the CD4 + cells count ranged from 40 to 1795/µl (conducted in 19 patients), and mean value of CD4 + cells was 365,31/µl, and mean HIV RNA titer was 287 118 copies/ml³. Of 28 HIV-infected persons 39 cases of opportunistic diseases developed in 12 patients (42.9%). In terms of the frequency of opportunistic diseases, tuberculosis (12 cases, 42.9%). Among a total of 28 HIV-infected patients, 6 (21.4%) of them died. This study characterizes the epidemiological and clinical patterns of HIV-infected patients in Tuzla region of Bosnia and Herzegovina to accurately understand HIV infection/AIDS in our region, in the hope to contribute in the establishment of effective HIV guidelines in the Tuzla region of B&H in the future.

Little is known about Clostridium difficile infection (CDI) in Asia. The aims of our study were to explore (i) the prevalence, risk factors and molecular epidemiology of CDI and colonization in a tertiary academic hospital in North-Eastern Peninsular Malaysia; (ii) the rate of carriage of C. difficile among the elderly in the region; (iii) the awareness level of this infection among the hospital staffs and students. For stool samples collected from hospital inpatients with diarrhea (n = 76) and healthy community members (n = 138), C. difficile antigen and toxins were tested by enzyme immunoassay. Stool samples were subsequently analyzed by culture and molecular detection of toxin genes, and PCR ribotyping of isolates. To examine awareness among hospital staff and students, participants were asked to complete a self-administered questionnaire. For the hospital and community studies, the prevalence of non-toxigenic C. difficile colonization was 16% and 2%, respectively. The prevalence of CDI among hospital inpatients with diarrhea was 13%. Out of 22 C. difficile strains from hospital inpatients, the toxigenic ribotypes 043 and 017 were most common (both 14%). In univariate analysis, C. difficile colonization in hospital inpatients was significantly associated with greater duration of hospitalization and use of penicillin (both P difficile colonization is prevalent in a Malaysian hospital setting but not in the elderly community with little or no contact with hospitals. Awareness of CDI is alarmingly poor.

Objective: To explore the desirability of setting a routine of test for detection of the serum markers of several viral infections hospitalized patients before anticipated blood exposure. Methods: Serum levels of five HBV markers, anti-HCV, anti-HIV (with ELISA) and ALT were determined in 214 hospitalized patients before forthcoming blood exposure as well as in 2468 controls. Results: The positive rate of each of the above-mentioned markers in the patients was: HBsAg 15.2% (397/2614), HBcAb- IgG 72.5% (1895/2614), anti-HCV 3.91% (102/2614), anti- HIV 0.08% (2/2614) and ALT level was above 40 u in 8.7% of the patients (227/2614). Each of the positive rate was significantly higher than that in the controls. Conclusion: There is a substantial portion of subjects harboring viral infections in the hospitalized patients. It is imperative to have these patients identified before blood exposure so that proper cautions can be taken and preventive measures implemented to minimize possible nosocomial as well as patients-to-staff infections. Moreover, any potential legal problems can also be appropriately dealt with. (authors)

Full Text Available Abstract Background During the Severe Acute Respiratory Syndrome (SARS outbreak, high compliance in healthcare workers to hand hygiene was primarily driven by fear. However, the post-SARS period confirmed that this practice was not sustainable. At the Singapore General Hospital, a 1,600-bedded acute tertiary care hospital, the hand hygiene program was revised in early 2007 following Singapore's signing of the pledge to the World Health Organization (WHO "Clean Care is Safer Care" program. Findings A multi-prong approach was used in designing the hand hygiene program. This included system change; training and education; evaluation and feedback; reminders in the workplace; and institutional safety climate. Hand hygiene compliance rate improved from 20% (in January 2007 to 61% (2010. Improvement was also seen annually in the compliance to each of the 5 moments as well as in all staff categories. Healthcare-associated MRSA infections were reduced from 0.6 (2007 to 0.3 (2010 per 1000 patient-days. Conclusions Leadership's support of the program evidenced through visible leadership presence, messaging and release of resources is the key factor in helping to make the program a true success. The hospital was recognised as a Global Hand Hygiene Expert Centre in January 2011. The WHO multi-prong interventions work in improving compliance and reducing healthcare associated infections.

To describe the epidemiology and rates of all health care-associated bloodstream infections (HA-BSIs) and of specific HA-BSI subsets in public hospitals in Queensland. Standardised HA-BSI surveillance data were collected in 23 Queensland public hospitals, 2008-2012. HA-BSIs were prospectively classified in terms of place of acquisition (inpatient, non-inpatient); focus of infection (intravascular catheter-associated, organ site focus, neutropenic sepsis, or unknown focus); and causative organisms. Inpatient HA-BSI rates (per 10,000 patient-days) were calculated. There were 8092 HA-BSIs and 9418 causative organisms reported. Inpatient HA-BSIs accounted for 79% of all cases. The focus of infection in 2792 cases (35%) was an organ site, intravascular catheters in 2755 (34%; including 2240 central line catheters), neutropenic sepsis in 1063 (13%), and unknown in 1482 (18%). Five per cent (117 of 2240) of central line-associated BSIs (CLABSIs) were attributable to intensive care units (ICUs). Eight groups of organisms provided 79% of causative agents: coagulase-negative staphylococci (18%), Staphylococcus aureus (15%), Escherichia coli (11%), Pseudomonas species (9%), Klebsiella pneumoniae/oxytoca (8%), Enterococcus species (7%), Enterobacter species (6%), and Candida species (5%). The overall inpatient HA-BSI rate was 6.0 per 10,000 patient-days. The rates for important BSI subsets included: intravascular catheter-associated BSIs, 1.9 per 10,000 patient-days; S. aureus BSIs, 1.0 per 10,000 patient-days; and methicillin-resistant S. aureus BSIs, 0.3 per 10,000 patient-days. The rate of HA-BSIs in Queensland public hospitals is lower than reported by similar studies elsewhere. About one-third of HA-BSIs are attributable to intravascular catheters, predominantly central venous lines, but the vast majority of CLABSIs are contracted outside ICUs. Different sources of HA-BSIs require different prevention strategies.

Full Text Available Background. It is a fact that hand hygiene prevents nosocomial infection, but compliance with recommended instructions is commonly poor. The purpose of this study was to implement a hand hygiene program for increase compliance with hand hygiene and its relationship with nosocomial infection (NI and MRSA infection/colonization rates. Methods. Compliance to hand hygiene was evaluated in a hospital by direct observation and measured of health care-associated infections, including methicillin resistant Staphylococcus aureus, before and after an educational intervention, using visual poster, colorful stamps, and feedback of the results. Results. Overall compliance did not increase during intervention, only handwashing before and after patient contact has improved from 40% to 76% (=0.01 for HCWs, but NI and MRSA rates remained high and stable. Conclusion. In a combination of high prevalence of NI and low compliance to hand hygiene, the programme of measure does not motivate the HCW hand hygiene. Future interventions should employ incremental evaluation to develop effective hand hygiene initiatives.

OBJECTIVE Prevention of Clostridium difficile infection (CDI) in acute-care hospitals is a priority for hospitals and clinicians. We performed a qualitative systematic review to update the evidence on interventions to prevent CDI published since 2009. DESIGN We searched Ovid, MEDLINE, EMBASE, The Cochrane Library, CINAHL, the ISI Web of Knowledge, and grey literature databases from January 1, 2009 to August 1, 2015. SETTING We included studies performed in acute-care hospitals. PATIENTS OR PARTICIPANTS We included studies conducted on hospitalized patients that investigated the impact of specific interventions on CDI rates. INTERVENTIONS We used the QI-Minimum Quality Criteria Set (QI-MQCS) to assess the quality of included studies. Interventions were grouped thematically: environmental disinfection, antimicrobial stewardship, hand hygiene, chlorhexidine bathing, probiotics, bundled approaches, and others. A meta-analysis was performed when possible. RESULTS Of 3,236 articles screened, 261 met the criteria for full-text review and 46 studies were ultimately included. The average quality rating was 82% according to the QI-MQCS. The most effective interventions, resulting in a 45% to 85% reduction in CDI, included daily to twice daily disinfection of high-touch surfaces (including bed rails) and terminal cleaning of patient rooms with chlorine-based products. Bundled interventions and antimicrobial stewardship showed promise for reducing CDI rates. Chlorhexidine bathing and intensified hand-hygiene practices were not effective for reducing CDI rates. CONCLUSIONS Daily and terminal cleaning of patient rooms using chlorine-based products were most effective in reducing CDI rates in hospitals. Further studies are needed to identify the components of bundled interventions that reduce CDI rates. Infect Control Hosp Epidemiol 2017;38:476-482.

There is an ongoing debate about the reasons for and factors contributing to healthcare-associated infection (HAI). Different solutions have been proposed over time to control the spread of HAI, with more focus on hand hygiene than on other aspects such as preventing the aerial dissemination of bacteria. Yet, it emerges that there is a need for a more pluralistic approach to infection control; one that reflects the complexity of the systems associated with HAI and involves multidisciplinary teams including hospital doctors, infection control nurses, microbiologists, architects, and engineers with expertise in building design and facilities management. This study reviews the knowledge base on the role that environmental contamination plays in the transmission of HAI, with the aim of raising awareness regarding infection control issues that are frequently overlooked. From the discussion presented in the study, it is clear that many unknowns persist regarding aerial dissemination of bacteria, and its control via cleaning and disinfection of the clinical environment. There is a paucity of good-quality epidemiological data, making it difficult for healthcare authorities to develop evidence-based policies. Consequently, there is a strong need for carefully designed studies to determine the impact of environmental contamination on the spread of HAI. © 2014 John Wiley & Sons A/S.

Objective  Infection following surgery is a serious complication, especially in neurosurgery. The aim of the study is to report the change of incidence rates of infection in patients undergoing elective neurosurgical procedures at a university hospital in South China as well as the risk factors. Material and Methods  The medical records and postoperative courses for patients undergoing 1,033 neurosurgical procedures from 2008 to 2014 were reviewed retrospectively to determine the incidence of neurosurgical infection, the identity of the offending organisms, and the factors associated with infection. Results  A total of 33 patients (40 cases) experienced postoperative infection representing 3.19% of the study population. Twenty cases were incision infections (1.94%), and 20 were cranial/spinal infections (1.94%) including 15 intracranial infections and 5 intraspinal infections. The 2.4-fold greater incidence of postoperative infection in 2008 to 2010 was compared with that in 2011 to 2014 with perioperative antibiotic prophylaxis ( p neurosurgery (1.08%). The most common offending organism was Staphylococcus aureus (27.5%). Foreign body implantation, operative time > 4 hours, and cerebrospinal fluid (CSF) leak (13 infections in 158 patients; p <0.001) were risk factors for infections ( p <0.05). Conclusion  The neurosurgical infection rate is usually low with perioperative antibiotic prophylaxis even in developing countries. Less foreign body implantation, shorter operative times, and controlling CSF leak could reduce infection rates. Georg Thieme Verlag KG Stuttgart · New York.

The classical Wells-Riley model for predicting risk of airborne transmission of diseases assumes a uniform spatial distribution of the infected cases in an enclosed space. A new mathematical model is developed here for predicting the spatial distribution of infection risk of airborne transmitted diseases by integrating the Wells-Riley equation into computational fluid dynamics. We applied our new integrated model to analyze a large nosocomial SARS outbreak in Hong Kong during the 2003 SARS epidemics, which was studied in the literature with regard to the association between airflow and SARS infection. The predicted numbers of infected cases of medical students in the same cubicle, the adjacent cubicle and the distant cubicle were 6.39, 0.78 and 0.2 respectively while the observed numbers of infected medical students in the three cubicles were 7, 0 and 0 respectively during the morning of March 6th, which was the highest attack period. The predicted numbers of infected cases of inpatients during the morning of March 6th in the same cubicle, the adjacent cubic and the distance cubicle were 7.8, 5.1, and 4.8 respectively which also agree well with the observed distribution of the infected inpatients during the entire infection period. The new developed model provides a new modelling tool for investigating the airborne transmission of diseases in enclosed spaces. The model is applicable when the susceptible stays mostly at the same location in an enclosed space during the infectious period, such as inpatients in a hospital ward, passengers in an airplane etc. (author)

To determine trends, mortality rates, and costs of antimicrobial resistance in invasive bacterial infections in hospitalized children, we analyzed data from Angkor Hospital for Children, Siem Reap, Cambodia, for 2007-2016. A total of 39,050 cultures yielded 1,341 target pathogens. Resistance rates were high; 82% each of Escherichia coli and Klebsiella pneumoniae isolates were multidrug resistant. Hospital-acquired isolates were more often resistant than community-acquired isolates; resistance trends over time were heterogeneous. K. pneumoniae isolates from neonates were more likely than those from nonneonates to be resistant to ampicillin-gentamicin and third-generation cephalosporins. In patients with community-acquired gram-negative bacteremia, third-generation cephalosporin resistance was associated with increased mortality rates, increased intensive care unit admissions, and 2.26-fold increased healthcare costs among survivors. High antimicrobial resistance in this setting is a threat to human life and the economy. In similar low-resource settings, our methods could be reproduced as a robust surveillance model for antimicrobial resistance.

Globally, More than 350 million individuals are chronically infected with hepatitis B virus (HBV), and >20 million of them are co-infected with hepatitis D virus (HDV). The aim of this study was to determine the pattern of HDV infection in patients with chronic hepatitis B in three main tertiary hospitals in Tripoli and Benghazi, Libya. This cross sectional and descriptive study was conducted on 162 patients with chronic hepatitis B positive for more than six months) who were followed up at hepatitis clinics of the three main tertiary hospitals in Tripoli city (88 patients from Tripoli Medical Centre and Tripoli Central Hospital) and Benghazi city (74 patients from Aljomhoria Hospital) during the period from January 2010 to June 2012. HBV and HDV markers were detected by enzyme linked fluorescent assay (ELFA) or enzyme-linked immunosorbent assay and HBV-DNA was quantified by real-time PCR techniques. The mean age of patients was 36,92 ± 15,35. One hundred and three (63.6%) of them were males and 59 (36,4%) were females. Four patients (2,5%) were tested positive for anti-HD antibodies, all of them have had clinical and/or histological diagnosis of cirrhosis. In multivariable regression analysis, age (p = .04), elevation of serum ALT (p = .03), elevation of serum AST (p = .04), and presence of cirrhosis (p = .003) were significantly related to HDV seropositivity. Although the study demonstrated that Libya has low to moderate prevalence of HDV (2,5%), it is important for policy makers and health care providers to continue the preventive measures for HDV spread, and HBV prevention program including utilization of HBV vaccine. Furthermore, it is imperative to screen chronic HBV patients for HDV for close observation for early diagnosis of subsequent development of liver cirrhosis. Moreover, further epidemiologic and genetic studies are needed to explore the trend for HDV infection in Libya. Copyright © 2017 Pan-Arab Association of Gastroenterology

Most patients are free in their choice of hospital for nonemergency admissions. In a nationwide survey in 1000 German households, we interviewed randomly chosen persons (age 14 and older) by phone about what they consider important when choosing a hospital. A standardized questionnaire was used. Additionally, question order was randomized prior to each interview. Demographic data included age, gender, education, and previous admissions to hospitals. Categories that might influence the choice of hospital included "distance to hospital," "friendly staff," "staff-to-patient ratio," "cleanliness," "nosocomial infection rate," "own experiences," "friend's opinion," and "facility's reputation in public media." General cleanliness, low nosocomial infection rates, and friendly staff proved to be the most important issues in our study. In contrast, the reputation of the health care facility in the public media was much less important. It seems that kindness and basic hygiene measures, both quite inexpensive factors, are key issues for patients.

Hospitalization due to dengue illness is an important measure of dengue morbidity. However, limited studies are based on administrative database because the validity of the diagnosis codes is unknown. We validated the International Classification of Diseases, 10th revision (ICD) diagnosis coding for dengue infections in the Malaysian Ministry of Health's (MOH) hospital discharge database. This validation study involves retrospective review of available hospital discharge records and hand-search medical records for years 2010 and 2013. We randomly selected 3219 hospital discharge records coded with dengue and non-dengue infections as their discharge diagnoses from the national hospital discharge database. We then randomly sampled 216 and 144 records for patients with and without codes for dengue respectively, in keeping with their relative frequency in the MOH database, for chart review. The ICD codes for dengue were validated against lab-based diagnostic standard (NS1 or IgM). The ICD-10-CM codes for dengue had a sensitivity of 94%, modest specificity of 83%, positive predictive value of 87% and negative predictive value 92%. These results were stable between 2010 and 2013. However, its specificity decreased substantially when patients manifested with bleeding or low platelet count. The diagnostic performance of the ICD codes for dengue in the MOH's hospital discharge database is adequate for use in health services research on dengue.

We surveyed US and Canadian pediatric hospitals about their use of central line-associated bloodstream infection (CLABSI) prevention strategies beyond typical insertion and maintenance bundles. We found wide variation in supplemental strategies across hospitals and in their penetration within hospitals. Future studies should assess specific adjunctive prevention strategies and CLABSI rates.

Restriction of antibiotic consumption to below predefined total use thresholds might remove the selection pressure that maintains antimicrobial resistance within populations. We assessed the effect of national antibiotic stewardship and infection prevention and control programmes on prevalence density of meticillin-resistant Staphylococcus aureus (MRSA) infections across a region of Scotland. This non-linear time-series analysis and quasi-experimental study explored ecological determinants of MRSA epidemiology among 1,289,929 hospital admissions and 455,508 adults registered in primary care in northeast Scotland. Interventions included antibiotic stewardship to restrict use of so-called 4C (cephalosporins, co-amoxiclav, clindamycin, and fluoroquinolones) and macrolide antibiotics; a hand hygiene campaign; hospital environment inspections; and MRSA admission screening. Total effects were defined as the difference between scenarios with intervention (observed) and without intervention (predicted from time-series models). The primary outcomes were prevalence density of MRSA infections per 1000 occupied bed days (OBDs) in hospitals or per 10,000 inhabitants per day (IDs) in the community. During antibiotic stewardship, use of 4C and macrolide antibiotics fell by 47% (mean decrease 224 defined daily doses [DDDs] per 1000 OBDs, 95% CI 154-305, p=0·008) in hospitals and 27% (mean decrease 2·52 DDDs per 1000 IDs, 0·65-4·55, p=0·031) in the community. Hospital prevalence densities of MRSA were inversely related to intensified infection prevention and control, but positively associated with MRSA rates in neighbouring hospitals, importation pressures, bed occupancy, and use of fluoroquinolones, co-amoxiclav, and third-generation cephalosporins, or macrolide antibiotics that exceeded hospital-specific thresholds. Community prevalence density was predicted by hospital MRSA rates and above-threshold use of macrolides, fluoroquinolones, and clindamycin. MRSA prevalence

To investigate the clinical epidemiologic characteristics and analyze risk factors for acute respiratory syncytial virus (RSV) infection in hospitalized infants with acute lower respiratory tract infection (ALRI). ALRI infants admitted to Children's Hospital of Fudan University from March 1st, 2011 to February 29th, 2012, were enrolled in this study. Patient information included demographic characteristics, feeding history, family status, clinical presentation, accessory examination, treatment and prognosis. According to the etiology of ALRI infants, we compared the seasonal distribution, demographic characteristics, household characteristics and underlying diseases between RSV-positive patients and RSV-negative patients. Univariate and multiple Logistic regression analyses were used to determine factors that were associated with risk of RSV infection. Among 1 726 ALRI infants, there were 913 RSV-positive infants (52.9%). The occurrence of RSV infection had a seasonal variation, with a peak in winter (59.1%). The median (P25, P75) age of RSV infants was 64 (21-155) days. The gestational age (GA) and body weight (BW) was (37.5 ± 2.4) weeks and (3.07 ± 0.66) kg, respectively. The male/female ratio among these was 1.9: 1. RSV infection was more popular among infants in the families with smoking members, crowded living conditions, history of atopic mother. Differences of the proportion of patients with underlying disease between RSV-positive and negative groups were statistically significant (59.4% vs. 54.2%, P infection were: GAinfection (OR = 1.351, 95%CI: 1.024-1.783; OR = 1.713, 95%CI: 1.332-2.204). Multivariate logistic regression determined the factors increasing the risk of RSV infection were: underlying CHD (OR = 1.298, 95%CI: 1.002-1.681), mother with atopic diseases (OR = 1.766, 95%CI: 1.237-2.520), autumn or winter infection (OR = 1.481, 95%CI: 1.105-1.985; OR = 1.766, 95%CI: 1.358-2.296). The prevalence of RSV infection was the highest in winter, while

Acute respiratory infections (ARIs) are a great public health challenge globally. The prevalence of respiratory viruses in patients with ARIs attending at different hospital settings is fully undetermined. Laboratory-based surveillance for ARIs was conducted at inpatient and outpatient settings of 11 hospitals in North China. The first 2-5 patients with ARIs were recruited in each hospital weekly from 2012 through 2015. The presence of respiratory viruses was screened by PCR assays. The prevalence of respiratory viruses was determined and compared between patients at different hospital settings. A total of 3487 hospitalized cases and 6437 outpatients/Emergency Department (ED) patients were enrolled. The most commonly detected viruses in the hospitalized cases were respiratory syncytial virus (RSV, 33.3%) in children less than two years old, adenoviruses (13.0%) in patients 15-34 years old, and influenza viruses (IFVs, 9.6%) in patients ≥65 years. IFVs were the most common virus in outpatient/ED patients across all age groups (22.7%). After controlling for the confounders caused by other viruses and covariates, adenoviruses (adjusted odds ratio [aOR]: 3.97, 99% confidence interval [99% CI]: 2.19-7.20) and RSV (aOR: 2.04, 99% CI: 1.34-3.11) were independently associated with increased hospitalization in children, as well as adenoviruses in adults (aOR: 2.14, 99% CI: 1.19-3.85). Additionally, co-infection of RSV with IFVs was associated with increased hospitalization in children (aOR: 12.20, 99% CI: 2.65-56.18). A substantial proportion of ARIs was associated with respiratory viruses in North China. RSV, adenoviruses, and co-infection of RSV and IFVs were more frequent in hospitalized children (or adenoviruses in adults), which might predict the severity of ARIs. Attending clinicians should be more vigilant of these infections.

Gastrointestinal and urinary tract pathogenic infections are aggravating the incidence and progression of the Human Immunodeficiency Virus (HIV) infection into Acquired Immune Deficiency Syndrome (AIDS) more especially in the developing countries. This study was conducted to assess the common gastrointestinal and urinary infections among HIV/AIDS patients at the Komfo Anokye Teaching Hospital (KATH) in Ghana between April and December 2008. This work reports on gastrointestinal and urinary tract pathogenic infections among 500 HIV seropositive and 300 HIV seronegative patients. There was a 35% (175/500) prevalence of intestinal parasites among HIV seropositive patients compared to 4.3% (13/300) in HIV seronegative patients. Giardia lamblia and Cryptosporidium accounted for 19% (95/500) and 14% (70/500) respectively, while Schistosoma mansoni, Strongyloides stercoralis and hookworm together accounted for 2% (10/500) of intestinal parasitic infections among the HIV seropositive patients. There was no significant difference (p > 0.05) in urinary parasitic infection between HIV seropositive 1% (2/500) and seronegative patients 0.7% (2/300). Most, 60 (86%) out of 70, of the urinary tract infection among the HIV seropositive patients was due to bacteria with E. coli being the most predominant isolate, 28 (47%) out of 60. There was no significant difference in infections based on age and gender. G. lamblia and Cryptosporidium were the most common gastrointestinal parasites detected while bacteria accounted for majority of the urinary tract infections among the HIV seropositive patients at the hospital.

Clostridium difficile infection (CDI) is associated with significant morbidity and mortality among adults. However, outcomes are poorly defined among children. A retrospective cohort study was performed among hospitalized children at 41 children's hospitals between January 2006 and August 2011. Patients with CDI (exposed) were matched 1:2 to patients without CDI (unexposed) based on the probability of developing CDI (propensity score derived from patient characteristics). Exposed subjects were stratified by C. difficile test date, suggestive of community-onset (CO) versus hospital-onset (HO) CDI. Outcomes were analyzed for matched subjects. We identified 5107 exposed and 693 409 unexposed subjects. Median age was 6 years (interquartile range [IQR], 2-13 years) for exposed and 8 years (IQR, 3-14 years) for unexposed subjects. Of these, 4474 exposed were successfully matched to 8821 unexposed by propensity score. In-hospital mortality differed significantly (CDI, 1.43% vs matched unexposed, 0.66%; P cost were significant: 5.55 days (95% CI, 4.54-6.56 days) and $18 900 (95% CI, $15 100-$22 700) for CO-CDI, and 21.60 days (95% CI, 19.29-23.90 days) and $93 600 (95% CI, $80 000-$107 200) for HO-CDI. Pediatric CDI is associated with increased mortality, longer LOS, and higher costs. These findings underscore the importance of antibiotic stewardship and infection control programs to prevent this disease in children.

Clostridium difficile infection (CDI) is a common complication to antibiotic use. Saccharomyces boulardii has shown effect as a prophylactic agent. We aimed to evaluate the efficacy of S. boulardii in preventing CDI in unselected hospitalized patients treated with antibiotics. We conducted a 1 year...... controlled prospective intervention study aiming to prescribe Sacchaflor (S. boulardii 5 × 109, Pharmaforce ApS) twice daily to hospitalized patients treated with antibiotics. Comparable departments from three other hospitals in our region were included as controls. All occurrences of CDI in patients...... receiving antibiotics were reported and compared to a baseline period defined as 2 years prior to intervention. Results were analyzed using run chart tests for non-random variation in CDI rates. In addition, odds ratios for CDI were calculated. S. boulardii compliance reached 44% at the intervention...

Abstract Background herpes zoster (HZ) is a common infection with potential complications requiring hospital care, especially for patients with multiple comorbities. However, there is little information on HZ from hospital registries. Methods we searched for hospital-based records of B02 code (ICD-10) between March 2000 and January 2017 at Hospital de Clínicas de Porto Alegre, a tertiary, university hospital in south Brazil. To avoid misclassifications, we considered clinical evaluation for the diagnosis of cutaneous HZ and postherpetic neuralgia (PHN), ophthalmological evaluation for ophthalmic HZ and the combination of clinical, radiologic and cerebrospinal fluid analysis for HZ meningo-encephalitis (ME). We analyzed conditions associated with immune dysregulation, complications, length of hospital stay, and mortality. Chi-square test and Kaplan-Meier estimator were used for statistical analyses. P < 0.05 was considered statistically significant. Results there were 847 records for this period, of which 801 were confirmed according to our criteria and included in the analysis. Most patients were women (n = 448; 60%), with an average of 48.8 years, standard deviation of 22.2. There were more diagnoses in the inpatients group (74.4%), and fewer in the emergency room (22.4%) and outpatient (3.3%). The median length of hospital stay was 7 days (2-10, P25-P75) when HZ was the main reason for admission. Most patients presented cutaneous HZ (n = 743, 92.8%). There were fewer cases of PHN (6.1%), ophthalmic HZ (7.6%) and ME (4.1%). Seventy percent had some kind of immune dysregulation; more frequently AIDS (31%), use of immunosuppressive agents (18.7%) and malignant disease (16.2%). We followed the subjects for a median of 28.2 (2.8-77.5) months. During this period, there were 105 (13.1%) deaths. Five were related to HZ ME. The 30-day overall mortality rate was 1.5%. There was no statistical difference in cumulative survival (graph 1, P = 0.05) or incidence of
