Sample records for clinical intervention system

  1. Selecting a clinical intervention documentation system for an academic setting. (United States)

    Fox, Brent I; Andrus, Miranda; Hester, E Kelly; Byrd, Debbie C


    Pharmacists' clinical interventions have been the subject of a substantial body of literature that focuses on the process and outcomes of establishing an intervention documentation program within the acute care setting. Few reports describe intervention documentation as a component of doctor of pharmacy (PharmD) programs; none describe the process of selecting an intervention documentation application to support the complete array of pharmacy practice and experiential sites. The process that a school of pharmacy followed to select and implement a school-wide intervention system to document the clinical and financial impact of an experiential program is described. Goals included finding a tool that allowed documentation from all experiential sites and the ability to assign dollar savings (hard and soft) to all documented interventions. The paper provides guidance for other colleges and schools of pharmacy in selecting a clinical intervention documentation system for program-wide use.

    AIM: To present our initial clinical experience using this innovative software solution for guidance of percutaneous structural heart disease interventions.METHODS: Left atrial appendage, atrial septal defect and paravalvular leak closure, transaortic valve repair and Mitra Clip procedures were performed in the catheter laboratory under fluoroscopic and echocardiographic guidance. The two-dimensional and three-dimensional images generated by the transesophageal echocardiography probe were interfaced with the fluoroscopic images in real-time using the Echo Navigator-system.RESULTS:The application of the novel image fusion technology was safe and led to a better appreciation of multimodality imaging guidance due to improved visualization of the complex relationship between catheter devices and anatomical structures.CONCLUSION:The Echo Navigator-system is a feasible and safe tool for guidance of interventional procedures in structural heart disease.This innovative technology may improve confidence of interventional cardiologists in targeting and positioning interventional devices in order to increase safety,accuracy,and efficacy of percutaneous interventions in the catheter laboratory.

  4. Electromagnetic tracking system for minimal invasive interventions using a C-arm system with CT option: first clinical results (United States)

    Nagel, Markus; Hoheisel, Martin; Bill, Ulrich; Klingenbeck-Regn, Klaus; Kalender, Willi A.; Petzold, Ralf


    To ensure precise needle placement in soft tissue of a patient for e.g. biopsies, the intervention is normally carried out image-guided. Whereas there are several imaging modalities such as computed tomography, magnetic resonance tomography, ultrasound, or C-arm X-ray systems with CT-option, navigation systems for such minimally invasive interventions are still quite rare. However, prototypes and also first commercial products of optical and electromagnetic tracking systems demonstrated excellent clinical results. Such systems provide a reduction of control scans, a reduction of intervention time, and an improved needle positioning accuracy specially for deep and double oblique access. Our novel navigation system CAPPA IRAD EMT with electromagnetic tracking for minimally invasive needle applications is connected to a C-arm imaging system with CT-option. The navigation system was investigated in clinical interventions by different physicians and with different clinical applications. First clinical results demonstrated a high accuracy during needle placement and a reduction of control scans.

    Full Text Available BACKGROUND: The "classic" endocannabinoid (eCB system includes the cannabinoid receptors CB1 and CB2, the eCB ligands anandamide (AEA and 2-arachidonoylglycerol (2-AG, and their metabolic enzymes. An emerging literature documents the "eCB deficiency syndrome" as an etiology in migraine, fibromyalgia, irritable bowel syndrome, psychological disorders, and other conditions. We performed a systematic review of clinical interventions that enhance the eCB system--ways to upregulate cannabinoid receptors, increase ligand synthesis, or inhibit ligand degradation. METHODOLOGY/PRINCIPAL FINDINGS: We searched PubMed for clinical trials, observational studies, and preclinical research. Data synthesis was qualitative. Exclusion criteria limited the results to 184 in vitro studies, 102 in vivo animal studies, and 36 human studies. Evidence indicates that several classes of pharmaceuticals upregulate the eCB system, including analgesics (acetaminophen, non-steroidal anti-inflammatory drugs, opioids, glucocorticoids, antidepressants, antipsychotics, anxiolytics, and anticonvulsants. Clinical interventions characterized as "complementary and alternative medicine" also upregulate the eCB system: massage and manipulation, acupuncture, dietary supplements, and herbal medicines. Lifestyle modification (diet, weight control, exercise, and the use of psychoactive substances--alcohol, tobacco, coffee, cannabis also modulate the eCB system. CONCLUSIONS/SIGNIFICANCE: Few clinical trials have assessed interventions that upregulate the eCB system. Many preclinical studies point to other potential approaches; human trials are needed to explore these promising interventions.

  6. Kyphoplasty interventions using a navigation system and C-arm CT data: first clinical results (United States)

    Hoheisel, Martin; Skalej, Martin; Beuing, Oliver; Bill, Ulrich; Klingenbeck-Regn, Klaus; Petzold, Ralf; Nagel, Markus H.


    This study evaluates new applications using a novel navigation system with electromagnetic (EM) tracking in clinical routine. The navigation system (iGuide CAPPA, CAS innovations, Erlangen, Germany) consists of a PC with dedicated navigation software, the AURORA tracking system (NDI, Waterloo Ontario, Canada; needles equipped with small coils in their tips for EM navigation. After patient positioning a 3D C-arm data set of the spine region of interest is acquired. The images are reconstructed and the 3D data set is directly transferred to the navigation system. Image loading and image to patient registration are performed automatically by the navigation system. For image acquisition a C-arm system with DynaCT option (AXIOM Artis, Siemens Healthcare, Forchheim, Germany) was used. As new clinical applications we performed kyphoplasty for reconstruction of collapsed vertebrae. All interventions were carried out without any complication. After a single planning scan the radiologists were able to place the needle in the designated vertebra. During needle driving 2D imaging was performed just in a few cases for control reasons. The time between planning and final needle positioning was reduced in all cases compared to conventional methods. Moreover, the number of control scans could be markedly reduced. The deviation of the needle to the planned target was less than 2 mm. The use of DynaCT images in combination with electromagnetic tracking-based navigation systems allows a precise needle positioning for kyphoplasty.

  7. Costing nursing care: using the clinical care classification system to value nursing intervention in an acute-care setting. (United States)

    Moss, Jacqueline; Saba, Virginia


    The purpose of this study was to combine an established methodology for coding nursing interventions and action types using the Clinical Care Classification System with a reliable formula (relative value units) to cost nursing services. Using a flat per-diem rate to cost nursing care greatly understates the actual costs and fails to address the high levels of variability within and across units. We observed nurses performing commonly executed nursing interventions and recorded these into an electronic database with corresponding Clinical Care Classification System codes. The duration of these observations was used to calculate intervention costs using relative value unit calculation formulas. The costs of the five most commonly executed interventions were nursing care coordination/manage-refer ($2.43), nursing status report/assess-monitor ($4.22), medication treatment/perform-direct ($6.33), physical examination/assess-monitor ($3.20), and universal precautions/perform-direct ($1.96). Future studies across a variety of nursing specialties and units are needed to validate the relative value unit for Clinical Care Classification System action types developed for use with the Clinical Care Classification System nursing interventions as a method to cost nursing care.

  13. A computer-assisted protocol for endovascular target interventions using a clinical MRI system for controlling untethered microdevices and future nanorobots. (United States)

    Martel, Sylvain; Mathieu, Jean-Baptiste; Felfoul, Ouajdi; Chanu, Arnaud; Aboussouan, Eric; Tamaz, Samer; Pouponneau, Pierre; Yahia, L'Hocine; Beaudoin, Gilles; Soulez, Gilles; Mankiewicz, Martin


    The possibility of automatically navigating untethered microdevices or future nanorobots to conduct target endovascular interventions has been demonstrated by our group with the computer-controlled displacement of a magnetic sphere along a pre-planned path inside the carotid artery of a living swine. However, although the feasibility of propelling, tracking and performing real-time closed-loop control of an untethered ferromagnetic object inside a living animal model with a relatively close similarity to human anatomical conditions has been validated using a standard clinical Magnetic Resonance Imaging (MRI) system, little information has been published so far concerning the medical and technical protocol used. In fact, such a protocol developed within technological and physiological constraints was a key element in the success of the experiment. More precisely, special software modules were developed within the MRI software environment to offer an effective tool for experimenters interested in conducting such novel interventions. These additional software modules were also designed to assist an interventional radiologist in all critical real-time aspects that are executed at a speed beyond human capability, and include tracking, propulsion, event timing and closed-loop position control. These real-time tasks were necessary to avoid a loss of navigation control that could result in serious injury to the patient. Here, additional simulation and experimental results for microdevices designed to be targeted more towards the microvasculature have also been considered in the identification, validation and description of a specific sequence of events defining a new computer-assisted interventional protocol that provides the framework for future target interventions conducted in humans.

  14. Multidisciplinary meetings as an effective clinical intervention. (United States)

    MacCallam, Jackie; Higgins, Lisa


    When used well, multidisciplinary meetings can function in the same way as other clinical interventions to improve communication, efficiency and outcomes. They help break down barriers, manage difficult emotions, and benefit service users and staff. But it is imperative that they are well prepared, well attended, and that the purpose and agenda are agreed. It is also vital to have an efficient chair and that meetings take place in an environment where feelings can be shared openly and respected. Services should recognise and address relevant training and support requirements.

    CareToy system is an innovative tele-rehabilitative tool, useful in providing intensive, individualized, home-based, family-centred Early Intervention (EI) in infants. Our aim was to evaluate, through a Randomized Clinical Trial (RCT) study, the effects of CareToy intervention on early motor and visual development in preterm infants. 41 preterm infants (range age: 3.0–5.9 months of corrected age) were enrolled and randomized into two groups, CareToy and Standard Care. 19 infants randomized in CareToy group performed a 4-week CareToy program, while 22 allocated to control group completed 4 weeks of Standard Care. Infant Motor Profile (IMP) was primary outcome measure, Alberta Infant Motor Scale (AIMS) and Teller Acuity Cards were secondary ones. Assessments were carried out at baseline (T0) and at the end of CareToy training or Standard Care period (T1). T1 was the primary endpoint. After RCT phase, 17 infants from control group carried out a 4-week CareToy program, while 18 infants from the CareToy group continued with Standard Care. At the end of this phase, infants were re-assessed at T2. In RCT phase, delta IMP total score and variation and performance sub-domains were significantly higher (P<0.050) in CareToy group if compared to Standard Care group. Similar results were found for Teller Acuity Cards, while no differences between groups were found for AIMS. No differences were found in any outcome measure results (T2-T0), between infants who started CareToy training before or after one month of standard care. This RCT study confirms the results of a previous pilot study, indicating that CareToy system can provide effective home-based EI.

  17. Admission Privileges and Clinical Responsibilities for Interventional Radiologists

    Energy Technology Data Exchange (ETDEWEB)

    Al-Kutoubi, Aghiad, E-mail: [The American University of Beirut Medical Center, IR Division, The Department of Diagnostic Radiology (Lebanon)


    Although clinical involvement by interventional radiologists in the care of their patients was advocated at the inception of the specialty, the change into the clinical paradigm has been slow and patchy for reasons related to pattern of practice, financial remuneration or absence of training. The case for the value of clinical responsibilities has been made in a number of publications and the consequences of not doing so have been manifest in the erosion of the role of the interventional radiologists particularly in the fields of peripheral vascular and neuro intervention. With the recent recognition of interventional radiology (IR) as a primary specialty in the USA and the formation of IR division in the Union of European Medical Specialists and subsequent recognition of the subspecialty in many European countries, it is appropriate to relook at the issue and emphasize the need for measures to promote the clinical role of the interventional radiologist.

  18. Music intervention study in abdominal surgery patients: challenges of an intervention study in clinical practice. (United States)

    Vaajoki, Anne; Pietilä, Anna-Maija; Kankkunen, Päivi; Vehviläinen-Julkunen, Katri


    Evidence-based nursing requires carefully designed interventions. This paper discusses methodological issues and explores practical solutions in the use of music intervention in pain management among adults after major abdominal surgery. There is a need to study nursing interventions that develop and test the effects of interventions to advanced clinical nursing knowledge and practice. There are challenges in carrying out intervention studies in clinical settings because of several interacting components and the length and complexity of the causal chains linking intervention with outcome. Intervention study is time-consuming and requires both researchers and participants' commitment to the study. Interdisciplinary and multiprofessional collaboration is also paramount. In this study, patients were allocated into the music group, in which patients listened to music 30 minutes at a time, or the control group, in which patients did not listen to any music during the same period.

    Djulbegovic Benjamin


    Full Text Available Abstract Background Randomised controlled clinical trials are performed to resolve uncertainty concerning comparator interventions. Appropriate acknowledgment of uncertainty enables the concurrent achievement of two goals : the acquisition of valuable scientific knowledge and an optimum treatment choice for the patient-participant. The ethical recruitment of patients requires the presence of clinical equipoise. This involves the appropriate choice of a control intervention, particularly when unapproved drugs or innovative interventions are being evaluated. Discussion We argue that the choice of a control intervention should be supported by a systematic review of the relevant literature and, where necessary, solicitation of the informed beliefs of clinical experts through formal surveys and publication of the proposed trial's protocol. Summary When clinical equipoise is present, physicians may confidently propose trial enrollment to their eligible patients as an act of therapeutic beneficence.

  20. Beef HACCP: intervention and non-intervention systems. (United States)

    Bolton, D J; Doherty, A M; Sheridan, J J


    While there are several generic beef HACCP documents available to the beef industry, these lack sufficient detail to be of any use other than as a general guide to HACCP. A document which clearly identifies and provides a sound scientific basis for potential critical control points (CCPs') and details critical limits, monitoring and corrective actions is clearly required. The objective of this paper is to provide such information. A detailed description of CCPs' for two different HACCP systems (an intervention and a non-intervention system) are presented and the advantages and disadvantages of each are discussed. Individual beef plants may then make an informed choice as to which HACCP system is most suitable for them and have all the specific information required for effective implementation.

  1. A triadic neurocognitive approach to addiction for clinical interventions. (United States)

    Noël, Xavier; Brevers, Damien; Bechara, Antoine


    According to the triadic neurocognitive model of addiction to drugs (e.g., cocaine) and non-drugs (e.g., gambling), weakened "willpower" associated with these behaviors is the product of an abnormal functioning in one or more of three key neural and cognitive systems: (1) an amygdala-striatum dependent system mediating automatic, habitual, and salient behaviors; (2) a prefrontal cortex dependent system important for self-regulation and forecasting the future consequences of a behavior; and (3) an insula dependent system for the reception of interoceptive signals and their translation into feeling states (such as urge and craving), which in turn plays a strong influential role in decision-making and impulse control processes related to uncertainty, risk, and reward. The described three-systems account for poor decision-making (i.e., prioritizing short-term consequences of a decisional option) and stimulus-driven actions, thus leading to a more elevated risk for relapse. Finally, this article elaborates on the need for "personalized" clinical model-based interventions targeting interactions between implicit processes, interoceptive signaling, and supervisory function aimed at helping individuals become less governed by immediate situations and automatic pre-potent responses, and more influenced by systems involved in the pursuit of future valued goals.

    Linde, K


    Although a considerable number of mostly quantitative surveys have investigated the frequency and circumstances of the use of placebo interventions in clinical practice, it remains rather unclear what role placebo interventions really have outside clinical and laboratory research and why they are used. In this article I discuss two aspects which have to be taken into account when future research aims to provide further insights: (1) the different perspectives of patients, providers and scientists when it comes to decide whether a treatment is a placebo or not and (2) the fact that applying placebos intentionally is not only an ethical but also a professional problem.

    We wanted to describe the practice and results of applying the day-hospital system in an interventional radiology clinic. From Oct. 2004 to Dec. 2005, the day-hospital system was applied to various interventional procedures with using a part of the recovery room of an angiography suite as a facility for hospital admission. The study included 91 cases in 73 patients. The source of the patient referral, the procedures, hospital courses and complications were analyzed and questionnaire surveys were conducted for the available 55 patients. Among the patients, 70% (n=64) were referred form other departments, 5% (n=5) from other hospitals, 5% (n=4) were new patients and 20% (n=18) were re-admissions. The procedures included gastrointestinal, biliary, urinary, hemodialysis related-and implantable port related interventions. 96% (n=87) of the patients were successfully discharged in a day and admission to the general ward was only 4% (n=4). Minor complications occurred after discharges in 3% (n=3). The questionnaire survey revealed that 96% (n=53) of the patients were satisfied with the service and they were not anxious after discharge. Most of common interventional procedures were safely done under the day-hospital system with the patients being highly satisfied. The day-hospital system can be a good tool for establishing admitting privileges for an interventional radiology clinic.

  12. Robotic systems for percutaneous needle-guided interventions. (United States)

    Kettenbach, Joachim; Kronreif, Gernot


    Several groups have developed robotic systems for invasive medical procedures. In this article we will focus on selected robotic systems for percutaneous needle-guided interventions using CT or MR imaging. We present six interventional robotic systems designed to work with imaging modalities such as CT, Cone-beam CT and MRI. The details of each system are given along with any phantom, animal, or human trials performed with each particular robot. Although each of these systems has specific features, they are all of great clinical value since they provide very stable needle guidance -- even for angulated approaches, they may allow access to lesions when the width of the CT- or MR- gantry would limit the access for a biopsy needle or other interventional tools such as thermal ablation probes. Then, such a robot may be able to guide the needle into the most promising region of the lesion without the need for a second contrast injection. Thus, more efficacious characterization and treatment, particularly for lesions that are difficult to target, can be anticipated. Although more research and clinical trials are certainly needed, it is, however, our belief that robotic systems will be an important part of future interventions.

  13. Interactive training system for interventional electrocardiology procedures. (United States)

    Talbot, Hugo; Spadoni, Federico; Duriez, Christian; Sermesant, Maxime; O'Neill, Mark; Jaïs, Pierre; Cotin, Stéphane; Delingette, Hervé


    Recent progress in cardiac catheterization and devices has allowed the development of new therapies for severe cardiac diseases like arrhythmias and heart failure. The skills required for such interventions are very challenging to learn, and are typically acquired over several years. Virtual reality simulators may reduce this burden by allowing trainees to practice such procedures without risk to patients. In this paper, we propose the first training system dedicated to cardiac electrophysiology, including pacing and ablation procedures. Our framework involves the simulation of a catheter navigation that reproduces issues intrinsic to intra-cardiac catheterization, and a graphics processing unit (GPU)-based electrophysiological model. A multithreading approach is proposed to compute both physical simulations (navigation and electrophysiology) asynchronously. With this method, we reach computational performances that account for user interactions in real-time. Based on a scenario of cardiac arrhythmia, we demonstrate the ability of the user-guided simulator to navigate inside vessels and cardiac cavities with a catheter and to reproduce an ablation procedure involving: extra-cellular potential measurements, endocardial surface reconstruction, electrophysiology mapping, radio-frequency (RF) ablation, as well as electrical stimulation. A clinical evaluation assessing the different aspects of the simulation is presented. This works is a step towards computerized medical learning curriculum.

    Evaluate the performance of a robotic system for CT-guided lung biopsy in comparison to the conventional manual technique. One hundred patients referred for CT-guided lung biopsy were randomly assigned to group A (robot-assisted procedure) or group B (conventional procedure). Size, distance from entry point and position in lung of target lesions were evaluated to assess homogeneity differences between the two groups. Procedure duration, dose length product (DLP), precision of needle positioning, diagnostic performance of the biopsy and rate of complications were evaluated to assess the clinical performance of the robotic system as compared to the conventional technique. All biopsies were successfully performed. The size (p = 0.41), distance from entry point (p = 0.86) and position in lung (p = 0.32) of target lesions were similar in both groups (p = 0.05). Procedure duration and radiation dose were significantly reduced in group A as compared to group B (p = 0.001). Precision of needle positioning, diagnostic performance of the biopsy and rate of complications were similar in both groups (p = 0.05). Robot-assisted CT-guided lung biopsy can be performed safely and with high diagnostic accuracy, reducing procedure duration and radiation dose in comparison to the conventional manual technique.

  16. Ethical clinical translation of stem cell interventions for neurologic disease

    DEFF Research Database (Denmark)

    Cote, David J; Bredenoord, Annelien L; Smith, Timothy R


    The application of stem cell transplants in clinical practice has increased in frequency in recent years. Many of the stem cell transplants in neurologic diseases, including stroke, Parkinson disease, spinal cord injury, and demyelinating diseases, are unproven-they have not been tested...... in prospective, controlled clinical trials and have not become accepted therapies. Stem cell transplant procedures currently being carried out have therapeutic aims, but are frequently experimental and unregulated, and could potentially put patients at risk. In some cases, patients undergoing such operations...... are not included in a clinical trial, and do not provide genuinely informed consent. For these reasons and others, some current stem cell interventions for neurologic diseases are ethically dubious and could jeopardize progress in the field. We provide discussion points for the evaluation of new stem cell...

  17. Clinical interventions for late-life anxious depression. (United States)

    Diefenbach, Gretchen J; Goethe, John


    Anxiety symptoms are frequently present in patients with late-life depression. The designation "anxious depression" has been used to describe major depressive disorder (MDD) accompanied by clinically significant but subsyndromal anxiety symptoms. MDD may also present comorbid with diagnosable anxiety disorders, although this presentation is less common in late life. Diagnosis of anxious depression in the elderly is complicated by several factors (eg, their tendency to experience and report psychiatric symptoms as somatic illness) and is associated with a more severe clinical presentation, increased risk for suicidal ideation, increased disability, and poorer prognosis. Standard pharmacotherapy for depression may be sufficient but for many patients must be modified or augmented. Psychosocial interventions may also be an important component in the treatment of these patients, although no specific psychosocial treatments have been developed for late-life anxious depression.

  18. Early intervention surveillance strategies (EISS) in dental student clinical performance: a mathematical approach. (United States)

    Tennant, Marc; Kruger, Estie


    Graduating dental practitioners requires the mastery of a number of skills and a significant body of basic information. Dental education is a complex combination of didactic and physical skill learning processes. It is necessary to develop appropriate tools to measure student clinical performance to allow the provision of interventional strategies at the right time targeted at the right individuals. In this study, an approach to early intervention surveillance strategies was developed that is cost-effective, transparent, and robust based on mathematical predictions of student clinical achievements. Using a cohort of students' clinical activity profile, a polynomial pair was developed that represents the predictive function of low and high achieving students. This polynomial pair can then be applied to students to predict their final achievement based on their current status. The polynomial methodology is adaptable to local variation such as access to clinical facilities. The early intervention surveillance strategy developed in this study provides a simple, cost-effective, predictive risk assessment system that relies on data sets already collected in most dental schools and can be completed without the need for significant human intervention. The mathematical approach allows the focusing of educational support towards students that require the assistance, thus augmenting the better use of resources.

  19. The clinical practice of interventional radiology: a European perspective.

    LENUS (Irish Health Repository)

    Keeling, Aoife N


    The purpose of this study was to determine the current clinical environment in which interventional radiology (IR) is practiced throughout Europe. A survey, comprising 12 questions on IR clinical practice, was sent to 1800 CIRSE members. Members were asked to return one survey per department. Two hundred seventy-four departments returned completed questionnaires, 22% from the United Kingdom (n = 60), 11% from Germany (n = 30), 8% from Austria (n = 23), and the remainder spread over Europe. Experts, with more than 10 years of IR experience, comprised 74% of the survey group. Almost one-third of the radiologists dedicated more than 80% of their clinical sessions to IR alone (27%; n = 75), with two-thirds practicing in a university teaching hospital setting (66%; n = 179). Few institutions have dedicated IR inpatient hospital beds (17%; n = 46), however, to compensate, day case beds are available (31%), IR admitting rights are in place (64% overall, 86% for in-patients, and 89% for day cases), and elective IR admissions can be made through other clinicians (87%). IR outpatient clinics are run at 26% of departments, with an average of two sessions per week. Dedicated nurses staff the majority of IR suites (82%), but clinical junior doctors are lacking (46%). Hospital management\\'s refusing access to beds was the most commonly cited reason for not developing a clinical IR service (41%). In conclusion, there is marked variation across European centers in the current practice of IR. Half do not have dedicated junior doctors and only a small minority have inpatient hospital beds. If IR is to be maintained as a dedicated clinical specialty, these issues need to be addressed urgently.

  20. Improving patient access to an interventional US clinic. (United States)

    Steele, Joseph R; Clarke, Ryan K; Terrell, John A; Brightmon, Tonya R


    A continuous quality improvement project was conducted to increase patient access to a neurointerventional ultrasonography (US) clinic. The clinic was experiencing major scheduling delays because of an increasing patient volume. A multidisciplinary team was formed that included schedulers, medical assistants, nurses, technologists, and physicians. The team created an Ishikawa diagram of the possible causes of the long wait time to the next available appointment and developed a flowchart of the steps involved in scheduling and completing a diagnostic US examination and biopsy. The team then implemented a staged intervention that included adjustments to staffing and room use (stage 1); new procedures for scheduling same-day add-on appointments (stage 2); and a lead technician rotation to optimize patient flow, staffing, and workflow (stage 3). Six months after initiation of the intervention, the mean time to the next available appointment had decreased from 25 days at baseline to 1 day, and the number of available daily appointments had increased from 38 to 55. These improvements resulted from a coordinated provider effort and had a net present value of more than $275,000. This project demonstrates that structural changes in staffing, workflow, and room use can substantially reduce scheduling delays for critical imaging procedures.

    The records of 208.777 (100%) clinical trials registered at were downloaded on the 19th of February 2016. Phase II and III trials including patients with glioblastoma were selected for further classification and analysis. Based on the disease settings, trials were classified into three groups: newly diagnosed glioblastoma, recurrent disease and trials with no differentiation according to disease setting. Furthermore, we categorized trials according to the experimental interventions, the primary sponsor, the source of financial support and trial design elements. Trends were evaluated using the autoregressive integrated moving average model. Two hundred sixteen (0.1%) trials were selected for further analysis. Academic centers (investigator initiated trials) were recorded as primary sponsors in 56.9% of trials, followed by industry 25.9%. Industry was the leading source of monetary support for the selected trials in 44.4%, followed by 25% of trials with primarily academic financial support. The number of newly initiated trials between 2005 and 2015 shows a positive trend, mainly through an increase in phase II trials, whereas phase III trials show a negative trend. The vast majority of trials evaluate forms of different systemic treatments (91.2%). In total, one hundred different molecular entities or biologicals were identified. Of those, 60% were involving drugs specifically designed for central nervous system malignancies. Trials that specifically address radiotherapy, surgery, imaging and other therapeutic or diagnostic methods appear to be rare. Current research in glioblastoma is mainly driven or sponsored by industry, academic medical oncologists and neuro-oncologists, with the majority of trials evaluating forms of systemic therapies. Few trials reach phase III. Imaging, radiation therapy and surgical procedures are underrepresented in current trials portfolios. Optimization in research portfolio for glioblastoma is needed.

  5. A network approach to clinical intervention in neurodegenerative diseases. (United States)

    Santiago, Jose A; Potashkin, Judith A


    Network biology has become a powerful tool to dissect the molecular mechanisms triggering neurodegeneration. Recent developments in network biology have led to the discovery of disease-causing genes, diagnostic biomarkers, and therapeutic targets for several neurodegenerative diseases including Alzheimer's, Parkinson's, and Huntington's diseases. Network-based approaches have provided the molecular rationale for the relationship among cancer, diabetes, and neurodegenerative diseases, and have uncovered unexpected links between apparently unrelated diseases. Here, we summarize the recent advances in network biology to untangle the molecular underpinnings giving rise to the most prevalent neurodegenerative diseases. We propose that network analysis provides a feasible and practical tool for identifying biologically meaningful biomarkers and potential therapeutic targets for clinical intervention in neurodegenerative diseases.

  6. Integrating Transgenic Vector Manipulation with Clinical Interventions to Manage Vector-Borne Diseases.

    Directory of Open Access Journals (Sweden)

    Kenichi W Okamoto


    Full Text Available Many vector-borne diseases lack effective vaccines and medications, and the limitations of traditional vector control have inspired novel approaches based on using genetic engineering to manipulate vector populations and thereby reduce transmission. Yet both the short- and long-term epidemiological effects of these transgenic strategies are highly uncertain. If neither vaccines, medications, nor transgenic strategies can by themselves suffice for managing vector-borne diseases, integrating these approaches becomes key. Here we develop a framework to evaluate how clinical interventions (i.e., vaccination and medication can be integrated with transgenic vector manipulation strategies to prevent disease invasion and reduce disease incidence. We show that the ability of clinical interventions to accelerate disease suppression can depend on the nature of the transgenic manipulation deployed (e.g., whether vector population reduction or replacement is attempted. We find that making a specific, individual strategy highly effective may not be necessary for attaining public-health objectives, provided suitable combinations can be adopted. However, we show how combining only partially effective antimicrobial drugs or vaccination with transgenic vector manipulations that merely temporarily lower vector competence can amplify disease resurgence following transient suppression. Thus, transgenic vector manipulation that cannot be sustained can have adverse consequences-consequences which ineffective clinical interventions can at best only mitigate, and at worst temporarily exacerbate. This result, which arises from differences between the time scale on which the interventions affect disease dynamics and the time scale of host population dynamics, highlights the importance of accounting for the potential delay in the effects of deploying public health strategies on long-term disease incidence. We find that for systems at the disease-endemic equilibrium, even

  8. Active ultrasound pattern injection system (AUSPIS for interventional tool guidance.

    Directory of Open Access Journals (Sweden)

    Xiaoyu Guo

    Full Text Available Accurate tool tracking is a crucial task that directly affects the safety and effectiveness of many interventional medical procedures. Compared to CT and MRI, ultrasound-based tool tracking has many advantages, including low cost, safety, mobility and ease of use. However, surgical tools are poorly visualized in conventional ultrasound images, thus preventing effective tool tracking and guidance. Existing tracking methods have not yet provided a solution that effectively solves the tool visualization and mid-plane localization accuracy problem and fully meets the clinical requirements. In this paper, we present an active ultrasound tracking and guiding system for interventional tools. The main principle of this system is to establish a bi-directional ultrasound communication between the interventional tool and US imaging machine within the tissue. This method enables the interventional tool to generate an active ultrasound field over the original imaging ultrasound signals. By controlling the timing and amplitude of the active ultrasound field, a virtual pattern can be directly injected into the US machine B mode display. In this work, we introduce the time and frequency modulation, mid-plane detection, and arbitrary pattern injection methods. The implementation of these methods further improves the target visualization and guiding accuracy, and expands the system application beyond simple tool tracking. We performed ex vitro and in vivo experiments, showing significant improvements of tool visualization and accurate localization using different US imaging platforms. An ultrasound image mid-plane detection accuracy of ±0.3 mm and a detectable tissue depth over 8.5 cm was achieved in the experiment. The system performance is tested under different configurations and system parameters. We also report the first experiment of arbitrary pattern injection to the B mode image and its application in accurate tool tracking.

  10. Clinical outcomes resulting from telemedicine interventions: a systematic review

    Directory of Open Access Journals (Sweden)

    Kraemer Dale


    Full Text Available Abstract Background The use of telemedicine is growing, but its efficacy for achieving comparable or improved clinical outcomes has not been established in many medical specialties. The objective of this systematic review was to evaluate the efficacy of telemedicine interventions for health outcomes in two classes of application: home-based and office/hospital-based. Methods Data sources for the study included deports of studies from the MEDLINE, EMBASE, CINAHL, and HealthSTAR databases; searching of bibliographies of review and other articles; and consultation of printed resources as well as investigators in the field. We included studies that were relevant to at least one of the two classes of telemedicine and addressed the assessment of efficacy for clinical outcomes with data of reported results. We excluded studies where the service did not historically require face-to-face encounters (e.g., radiology or pathology diagnosis. All included articles were abstracted and graded for quality and direction of the evidence. Results A total of 25 articles met inclusion criteria and were assessed. The strongest evidence for the efficacy of telemedicine in clinical outcomes comes from home-based telemedicine in the areas of chronic disease management, hypertension, and AIDS. The value of home glucose monitoring in diabetes mellitus is conflicting. There is also reasonable evidence that telemedicine is comparable to face-to-face care in emergency medicine and is beneficial in surgical and neonatal intensive care units as well as patient transfer in neurosurgery. Conclusions Despite the widespread use of telemedicine in virtually all major areas of health care, evidence concerning the benefits of its use exists in only a small number of them. Further randomized controlled trials must be done to determine where its use is most effective.

  11. Rationale and clinical data supporting nutritional intervention in Alzheimer's disease. (United States)

    Engelborghs, S; Gilles, C; Ivanoiu, A; Vandewoude, M


    Adequate nutrition plays an important role in the maintenance of cognitive function, particularly during aging. Malnutrition is amongst the risk factors for developing mild cognitive impairment (MCI) and Alzheimer's disease (AD). Epidemiological studies have associated deficiencies in some nutrients with a higher risk of cognitive dysfunction and/or AD. Cognitive decline in AD is correlated with synaptic loss and many of the components required to maintain optimal synaptic function are derived from dietary sources. As synapses are part of the neuronal membrane and are continuously being remodelled, the availability of sufficient levels of nutritional precursors (mainly uridine monophosphate, choline and omega-3 fatty acids) to make the phospholipids required to build neuronal membranes may have beneficial effects on synaptic degeneration in AD. In addition, B-vitamins, phospholipids and other micronutrients act as cofactors to enhance the supply of precursors required to make neuronal membranes and synapses. Despite this, no randomized controlled trial has hitherto provided evidence that any single nutrient has a beneficial effect on cognition or lowers the risk for AD. However, a multi-target approach using combinations of (micro)nutrients might have beneficial effects on cognitive function in neurodegenerative brain disorders like AD leading to synaptic degeneration. Here we review the clinical evidence for supplementation, based on a multi-target approach with a focus on key nutrients with a proposed role in synaptic dysfunction. Based on preclinical evidence, a nutrient mixture, Souvenaid(®) (Nutricia N.V., Zoetermeer, The Netherlands) was developed. Clinical trials with Souvenaid(®) have shown improved memory performance in patients with mild AD. Further clinical trials to evaluate the effects of nutritional intervention in MCI and early dementia due to AD are on-going.

  12. Music intervention as system: reversing hyper systemising in autism spectrum disorders to the comprehension of music as intervention. (United States)

    Jaschke, Artur C


    This paper seeks to combine the notion of the Empathising-Systemising (E-S) theory and the resulting twist from the executive dysfunction theory in autism spectrum conditions (ASC) in light of music intervention as system. To achieve these points it will be important to re-visit, nonetheless briefly, the above mentioned theories and re-define music intervention in the light of these. Furthermore there is the need to adjust the executive dysfunction theory to a theory of dysfunctioning executive functions. These notions will create a different understanding of music intervention in this context, allowing the development of future and existing music intervention programs applied clinically. These applications will evolve around a structuralised approach to music intervention as system, proposing five consecutive systems. It will therefore argue the aspects of expanding existing theories in ASC together with the call for generalised interventions to better assess autism from a theoretical point of view. Theories have to be updated in a time of fast and ever-changing development.

  13. Application of balanced scorecard in the evaluation of a complex health system intervention: 12 months post intervention findings from the BHOMA intervention: a cluster randomised trial in Zambia.

    Directory of Open Access Journals (Sweden)

    Wilbroad Mutale

    Full Text Available INTRODUCTION: In many low income countries, the delivery of quality health services is hampered by health system-wide barriers which are often interlinked, however empirical evidence on how to assess the level and scope of these barriers is scarce. A balanced scorecard is a tool that allows for wider analysis of domains that are deemed important in achieving the overall vision of the health system. We present the quantitative results of the 12 months follow-up study applying the balanced scorecard approach in the BHOMA intervention with the aim of demonstrating the utility of the balanced scorecard in evaluating multiple building blocks in a trial setting. METHODS: The BHOMA is a cluster randomised trial that aims to strengthen the health system in three rural districts in Zambia. The intervention aims to improve clinical care quality by implementing practical tools that establish clear clinical care standards through intensive clinic implementations. This paper reports the findings of the follow-up health facility survey that was conducted after 12 months of intervention implementation. Comparisons were made between those facilities in the intervention and control sites. STATA version 12 was used for analysis. RESULTS: The study found significant mean differences between intervention(I and control (C sites in the following domains: Training domain (Mean I:C; 87.5.vs 61.1, mean difference 23.3, p = 0.031, adult clinical observation domain (mean I:C; 73.3 vs.58.0, mean difference 10.9, p = 0.02 and health information domain (mean I:C; 63.6 vs.56.1, mean difference 6.8, p = 0.01. There was no gender differences in adult service satisfaction. Governance and motivation scores did not differ between control and intervention sites. CONCLUSION: This study demonstrates the utility of the balanced scorecard in assessing multiple elements of the health system. Using system wide approaches and triangulating data collection methods seems to be

    LeMay KS


    Full Text Available Background: Pharmacists in Australia are accessible health care professionals, and their provision of clinical pharmacy interventions in a range of areas has been proven to improve patient outcomes. Individual clinical pharmacy interventions in the area of asthma management have been very successful. An understanding of the nature of these interventions will inform future pharmacy services. What we do not know is when pharmacists provide a complex asthma service, what elements of that service (interventions they choose to deliver. Objective: To explore the scope and frequency of asthma-related clinical interventions provided by pharmacists to patients in an evidence-based complex asthma service. Methods: Pharmacists from 4 states/territories of Australia were trained in asthma management. People with asthma had 3 or 4 visits to the pharmacy. Guided by a structured patient file, the pharmacist assessed the patient’s asthma and management and provided interventions where and when considered appropriate, based on their clinical decision making skills. The interventions were recorded in a checklist in the patient file. They were then analysed descriptively and thematically. Results: Pharmacists provided 22,909 clinical pharmacy interventions over the service to 570 patients (398 of whom completed the service. The most frequently delivered interventions were in the themes ‘Education on asthma’, ‘Addressing trigger factors’, ‘Medications – safe and effective use’ and ‘Explore patient perspectives’. The patients had a high and ongoing need for interventions. Pharmacists selected interventions based on their assessment of perceived need then revisited and reinforced these interventions. Conclusion: Pharmacists identified a number of areas in which patients required interventions to assist with their asthma management. Many of these were perceived to require continuing reinforcement over the duration of the service. Pharmacists were

  15. Beyond clinical engagement: a pragmatic model for quality improvement interventions, aligning clinical and managerial priorities. (United States)

    Pannick, Samuel; Sevdalis, Nick; Athanasiou, Thanos


    Despite taking advantage of established learning from other industries, quality improvement initiatives in healthcare may struggle to outperform secular trends. The reasons for this are rarely explored in detail, and are often attributed merely to difficulties in engaging clinicians in quality improvement work. In a narrative review of the literature, we argue that this focus on clinicians, at the relative expense of managerial staff, has proven counterproductive. Clinical engagement is not a universal challenge; moreover, there is evidence that managers-particularly middle managers-also have a role to play in quality improvement. Yet managerial participation in quality improvement interventions is often assumed, rather than proven. We identify specific factors that influence the coordination of front-line staff and managers in quality improvement, and integrate these factors into a novel model: the model of alignment. We use this model to explore the implementation of an interdisciplinary intervention in a recent trial, describing different participation incentives and barriers for different staff groups. The extent to which clinical and managerial interests align may be an important determinant of the ultimate success of quality improvement interventions.

  16. Continuous-Time System Identification of a Smoking Cessation Intervention. (United States)

    Timms, Kevin P; Rivera, Daniel E; Collins, Linda M; Piper, Megan E


    Cigarette smoking is a major global public health issue and the leading cause of preventable death in the United States. Toward a goal of designing better smoking cessation treatments, system identification techniques are applied to intervention data to describe smoking cessation as a process of behavior change. System identification problems that draw from two modeling paradigms in quantitative psychology (statistical mediation and self-regulation) are considered, consisting of a series of continuous-time estimation problems. A continuous-time dynamic modeling approach is employed to describe the response of craving and smoking rates during a quit attempt, as captured in data from a smoking cessation clinical trial. The use of continuous-time models provide benefits of parsimony, ease of interpretation, and the opportunity to work with uneven or missing data.

  17. Preliminary Evaluation of a MRI-compatible Modular Robotic System for MRI-guided Prostate Interventions. (United States)

    Song, Sang-Eun; Cho, Nathan; Tokuda, Junichi; Hata, Nobuhiko; Tempany, Clare; Fichtinger, Gabor; Iordachita, Iulian


    Magnetic Resonance Imaging (MRI) guided robotic interventions have been introduced in order to advance prostate cancer detection and treatment. To overcome problems of such robotic interventions, we have been developing a pneumatically actuated MRI-compatible modular robotic system for MRI-guided transperineal prostate intervention and its interventional procedure. For system evaluation, a series of experiments have been conducted and this paper reports a needle insertion experiment using prostate phantom and patient mockup trials. The needle insertion experiment resulted in noticeable consistent error in one direction, which we will investigate further. Nonetheless, patient mockup experiences suggest that the modular robotic system and its interventional procedure are well integrated and implemented in clinical environment.

  18. The clinical information system implementation evaluation scale. (United States)

    Gugerty, Brian; Maranda, Michael; Rook, Dona


    Measurement instruments to assess user satisfaction with Clinical Information Systems (CIS) and with the implementation of CIS are needed as part of multi-faceted evaluation of CIS. Seven years of experience in developing measurement instruments to assess staff satisfaction with CIS preceded the development effort that created the Clinical Information System Evaluation Scale (CISIES). The scale was developed using precursors of the CISIES and it was guided by an expert panel. Following its construction the 37-item measurement instrument was piloted as part of the assessment of a Critical Care Clinical Information System implementation at a medical center in Florida, USA. Results indicated satisfaction with the implementation, although not strong, at the time of administration. The results of the CISIES administration were used by informaticians at the research site to plan and execute an intervention to improve satisfaction with the implementation. Re-administration of the CISIES at the site to evaluate the success of this intervention is planned. The CISIES was found to be a useful instrument, easy to administer, acceptable to respondents, easy to score and understandable by non-researcher at the study site. Early indications are that it will be useful in the formative and summative evaluation of CIS implementations.

    Full Text Available As colleges of pharmacy prepare a new generation of practitioners, it is important that during practice experiences students learn the impact of clinical interventions. For over ten years, pharmacy students have been a vital part of the multidisciplinary team at the military treatment facility. The overall impact of the student interventions on patient care has not been evaluated. To evaluate the impact, the students began documenting their clinical interventions in Medkeeper RxInterventions™, an online database. The program is used to document faculty and fourth year pharmacy students’ pharmaceutical interventions.Objective: The objective of this study was to analyze the interventions completed by fourth year pharmacy students during a general medicine advanced pharmacy practice experience at a military treatment facility.Methods: The students completing their general medicine advanced pharmacy practice experience at the military treatment facility are responsible for self reporting all interventions made during clinical rounds into the Medkeeper RxIntervention™ database. The researchers retrospectively collected and analyzed interventions made from June 2008 to June 2009.Results: The total number of interventions recorded by 8 fourth year pharmacy students was 114. Students averaged a number of 14.3 interventions during an eight week practice experience. Students spent an average of 5 minutes per intervention. Ninety- five percent of the interventions were accepted.Conclusion: Fourth year pharmacy students’ recommendations were accepted at a high rate by resident physicians. The high acceptance rate may have the ability to positively impact patient care.

  4. Alzheimer’s disease multiple intervention trial (ADMIT: study protocol for a randomized controlled clinical trial

    Directory of Open Access Journals (Sweden)

    Callahan Christopher M


    Full Text Available Abstract Background Given the current lack of disease-modifying therapies, it is important to explore new models of longitudinal care for older adults with dementia that focus on improving quality of life and delaying functional decline. In a previous clinical trial, we demonstrated that collaborative care for Alzheimer’s disease reduces patients’ neuropsychiatric symptoms as well as caregiver stress. However, these improvements in quality of life were not associated with delays in subjects’ functional decline. Trial design Parallel randomized controlled clinical trial with 1:1 allocation. Participants A total of 180 community-dwelling patients aged ≥45 years who are diagnosed with possible or probable Alzheimer’s disease; subjects must also have a caregiver willing to participate in the study and be willing to accept home visits. Subjects and their caregivers are enrolled from the primary care and geriatric medicine practices of an urban public health system serving Indianapolis, Indiana, USA. Interventions All patients receive best practices primary care including collaborative care by a dementia care manager over two years; this best practices primary care program represents the local adaptation and implementation of our prior collaborative care intervention in the urban public health system. Intervention patients also receive in-home occupational therapy delivered in twenty-four sessions over two years in addition to best practices primary care. The focus of the occupational therapy intervention is delaying functional decline and helping both subjects and caregivers adapt to functional impairments. The in-home sessions are tailored to the specific needs and goals of each patient-caregiver dyad; these needs are expected to change over the course of the study. Objective To determine whether best practices primary care plus home-based occupational therapy delays functional decline among patients with Alzheimer’s disease compared

  6. Ubiquitous Multicriteria Clinic Recommendation System. (United States)

    Chen, Toly


    Advancements in information, communication, and sensor technologies have led to new opportunities in medical care and education. Patients in general prefer visiting the nearest clinic, attempt to avoid waiting for treatment, and have unequal preferences for different clinics and doctors. Therefore, to enable patients to compare multiple clinics, this study proposes a ubiquitous multicriteria clinic recommendation system. In this system, patients can send requests through their cell phones to the system server to obtain a clinic recommendation. Once the patient sends this information to the system, the system server first estimates the patient's speed according to the detection results of a global positioning system. It then applies a fuzzy integer nonlinear programming-ordered weighted average approach to assess four criteria and finally recommends a clinic with maximal utility to the patient. The proposed methodology was tested in a field experiment, and the experimental results showed that it is advantageous over two existing methods in elevating the utilities of recommendations. In addition, such an advantage was shown to be statistically significant.

  8. Minimal intervention dentistry - a new frontier in clinical dentistry. (United States)

    Mm, Jingarwar; Nk, Bajwa; A, Pathak


    Minimally invasive procedures are the new paradigm in health care. Everything from heart bypasses to gall bladder, surgeries are being performed with these dynamic new techniques. Dentistry is joining this exciting revolution as well. Minimally invasive dentistry adopts a philosophy that integrates prevention, remineralisation and minimal intervention for the placement and replacement of restorations. Minimally invasive dentistry reaches the treatment objective using the least invasive surgical approach, with the removal of the minimal amount of healthy tissues. This paper reviews in brief the concept of minimal intervention in dentistry.

    Bossi, Larraine M; Ott, Mary Jane; DeCristofaro, Susan


    Oncology nurses and their patients are frequently on the cutting edge of new therapies and interventions that support coping, health, and healing. Reiki is a practice that is requested with increasing frequency, is easy to learn, does not require expensive equipment, and in preliminary research, elicits a relaxation response and helps patients to feel more peaceful and experience less pain. Those who practice Reiki report that it supports them in self-care and a healthy lifestyle. This article will describe the process of Reiki, review current literature, present vignettes of patient responses to the intervention, and make recommendations for future study.

  12. Interventional multispectral photoacoustic imaging with a clinical linear array ultrasound probe for guiding nerve blocks (United States)

    Xia, Wenfeng; West, Simeon J.; Nikitichev, Daniil I.; Ourselin, Sebastien; Beard, Paul C.; Desjardins, Adrien E.


    Accurate identification of tissue structures such as nerves and blood vessels is critically important for interventional procedures such as nerve blocks. Ultrasound imaging is widely used as a guidance modality to visualize anatomical structures in real-time. However, identification of nerves and small blood vessels can be very challenging, and accidental intra-neural or intra-vascular injections can result in significant complications. Multi-spectral photoacoustic imaging can provide high sensitivity and specificity for discriminating hemoglobin- and lipid-rich tissues. However, conventional surface-illumination-based photoacoustic systems suffer from limited sensitivity at large depths. In this study, for the first time, an interventional multispectral photoacoustic imaging (IMPA) system was used to image nerves in a swine model in vivo. Pulsed excitation light with wavelengths in the ranges of 750 - 900 nm and 1150 - 1300 nm was delivered inside the body through an optical fiber positioned within the cannula of an injection needle. Ultrasound waves were received at the tissue surface using a clinical linear array imaging probe. Co-registered B-mode ultrasound images were acquired using the same imaging probe. Nerve identification was performed using a combination of B-mode ultrasound imaging and electrical stimulation. Using a linear model, spectral-unmixing of the photoacoustic data was performed to provide image contrast for oxygenated and de-oxygenated hemoglobin, water and lipids. Good correspondence between a known nerve location and a lipid-rich region in the photoacoustic images was observed. The results indicate that IMPA is a promising modality for guiding nerve blocks and other interventional procedures. Challenges involved with clinical translation are discussed.

  14. Self-management support interventions that are clinically linked and technology enabled: can they successfully prevent and treat diabetes? (United States)

    Kaufman, Neal D; Woodley, Paula D Patnoe


    Patients with diabetes need a complex set of services and supports. The challenge of integrating these services into the diabetes regimen can be successfully overcome through self-management support interventions that are clinically linked and technology enabled: self-management support because patients need help mastering the knowledge, attitudes, skills, and behaviors so necessary for good outcomes; interventions because comprehensive theory-based, evidence-proven, long-term, longitudinal interventions work better than direct-to-consumer or nonplanned health promotion approaches; clinically linked because patients are more likely to adopt new behaviors when the approach is in the context of a trusted therapeutic relationship and within an effective medical care system; and technology enabled because capitalizing on the amazing power of information technology leads to the delivery of cost-effective, scalable, engaging solutions that prevent and manage diabetes.

  15. PLUS: open-source toolkit for ultrasound-guided intervention systems. (United States)

    Lasso, Andras; Heffter, Tamas; Rankin, Adam; Pinter, Csaba; Ungi, Tamas; Fichtinger, Gabor


    A variety of advanced image analysis methods have been under the development for ultrasound-guided interventions. Unfortunately, the transition from an image analysis algorithm to clinical feasibility trials as part of an intervention system requires integration of many components, such as imaging and tracking devices, data processing algorithms, and visualization software. The objective of our paper is to provide a freely available open-source software platform-PLUS: Public software Library for Ultrasound-to facilitate rapid prototyping of ultrasound-guided intervention systems for translational clinical research. PLUS provides a variety of methods for interventional tool pose and ultrasound image acquisition from a wide range of tracking and imaging devices, spatial and temporal calibration, volume reconstruction, simulated image generation, and recording and live streaming of the acquired data. This paper introduces PLUS, explains its functionality and architecture, and presents typical uses and performance in ultrasound-guided intervention systems. PLUS fulfills the essential requirements for the development of ultrasound-guided intervention systems and it aspires to become a widely used translational research prototyping platform. PLUS is freely available as open source software under BSD license and can be downloaded from

  16. Why economic analysis of health system improvement interventions matters

    Directory of Open Access Journals (Sweden)

    Edward Ivor Broughton


    Full Text Available There is little evidence to direct health systems toward providing efficient interventions to address medical errors, defined as an unintended act of omission or commission or one not executed as intended that may or may not cause harm to the patient but does not achieve its intended outcome. We believe that lack of guidance on what is the most efficient way to reduce adverse events and improve the quality of health care limits the scale-up of health system improvement interventions. Challenges to economic evaluation of these interventions include defining and implementing improvement interventions in different settings with high fidelity, capturing all of the positive and negative effects of the intervention, using process measures of effectiveness rather than health outcomes, and determining the full cost of the intervention and all economic consequences its effects. However, health system improvement interventions should be treated similarly to individual medical interventions and undergo rigorous economic evaluation to provide actionable evidence to guide policy-makers in decisions of resources allocation for improvement activities among other competing demands for health care resources.

    Myint-U, Athi; Bull, Sheana; Greenwood, Gregory L; Patterson, Jocelyn; Rietmeijer, Cornelis A; Vrungos, Shelley; Warner, Lee; Moss, Jesse; O'Donnell, Lydia N


    There is a strong need for inexpensive, easily administered HIV and STD prevention interventions that are highly replicable and appealing to diverse clinic audiences. This article describes the four-step iterative and collaborative process used by the Safe City Study Group to design and develop a brief video-based intervention: Safe in the City. Step 1 involves identification of an appropriate intervention medium, a theoretical framework, and key messages; Step 2, collaboration with a film company to integrate the framework and key messages into an entertaining product; Step 3, facilitation of a multistep participatory process involving input from members of the priority audience (clinic patients), clinic staff, and community reviewers; and Step 4, pilot-testing to determine structural barriers to patients' viewing the video in clinic waiting rooms. Safe in the City has been demonstrated to reduce incident STDs among clinic patients in three cities in the United States.

  1. Expert systems in clinical microbiology. (United States)

    Winstanley, Trevor; Courvalin, Patrice


    This review aims to discuss expert systems in general and how they may be used in medicine as a whole and clinical microbiology in particular (with the aid of interpretive reading). It considers rule-based systems, pattern-based systems, and data mining and introduces neural nets. A variety of noncommercial systems is described, and the central role played by the EUCAST is stressed. The need for expert rules in the environment of reset EUCAST breakpoints is also questioned. Commercial automated systems with on-board expert systems are considered, with emphasis being placed on the "big three": Vitek 2, BD Phoenix, and MicroScan. By necessity and in places, the review becomes a general review of automated system performances for the detection of specific resistance mechanisms rather than focusing solely on expert systems. Published performance evaluations of each system are drawn together and commented on critically.

  2. Yoga & Cancer Interventions: A Review of the Clinical Significance of Patient Reported Outcomes for Cancer Survivors

    Directory of Open Access Journals (Sweden)

    S. Nicole Culos-Reed


    Full Text Available Limited research suggests yoga may be a viable gentle physical activity option with a variety of health-related quality of life, psychosocial and symptom management benefits. The purpose of this review was to determine the clinical significance of patient-reported outcomes from yoga interventions conducted with cancer survivors. A total of 25 published yoga intervention studies for cancer survivors from 2004–2011 had patient-reported outcomes, including quality of life, psychosocial or symptom measures. Thirteen of these studies met the necessary criteria to assess clinical significance. Clinical significance for each of the outcomes of interest was examined based on 1 standard error of the measurement, 0.5 standard deviation, and relative comparative effect sizes and their respective confidence intervals. This review describes in detail these patient-reported outcomes, how they were obtained, their relative clinical significance and implications for both clinical and research settings. Overall, clinically significant changes in patient-reported outcomes suggest that yoga interventions hold promise for improving cancer survivors' well-being. This research overview provides new directions for examining how clinical significance can provide a unique context for describing changes in patient-reported outcomes from yoga interventions. Researchers are encouraged to employ indices of clinical significance in the interpretation and discussion of results from yoga studies.

    Sieving, Renee E; McMorris, Barbara J; Secor-Turner, Molly; Garwick, Ann W; Shlafer, Rebecca; Beckman, Kara J; Pettingell, Sandra L; Oliphant, Jennifer A; Seppelt, Ann M


    Prime Time, a youth development intervention, aims to reduce multiple risk behaviors among adolescent girls seeking clinic services who are at high risk for pregnancy. The purpose of the current study was to examine whether Prime Time involvement produced changes in relational aggression, physical violence, and related psychosocial and behavioral outcomes. Qualitative case exemplars illustrated social contexts of intervention participants with differing longitudinal patterns of relational aggression and physical violence. Data were from a randomized efficacy trial with 13-17 year-old girls (n = 253) meeting specified risk criteria. Intervention participants were involved in Prime Time and usual clinic services for 18 months, control participants received usual clinic services. Participants in the current study completed self-report surveys at baseline and 18 months following enrollment. Outcomes analyses revealed significantly lower levels of relational aggression perpetration in the intervention group versus controls. In contrast, Prime Time involvement did not result in significant reductions in physical violence. Exploratory dose-response analyses indicated that reductions in relational aggression may have been most pronounced among girls actively involved in Prime Time case management and peer leadership activities. Qualitative findings suggested that the intervention's emphasis on modeling and building supportive relationships contributed to reductions in relational aggression. This study contributes to what has been a very limited evidence base regarding effective approaches to preventing violence among high-risk adolescent girls. Findings suggest that offering youth development interventions through clinic settings hold promise in reducing violence risk among vulnerable youth.

    Asher Maya


    Full Text Available Abstract Background The elderly population consumes a large share of medical resources in the western world. A significant portion of the expense is related to hospitalizations. Objectives To evaluate an intervention program designed to reduce the number of hospitalization of elderly patients by a more optimal allocation of resources in primary care. Methods A multidimensional intervention program was conducted that included the re-engineering of existing work processes with a focus on the management of patient problems, improving communication with outside agencies, and the establishment of a system to monitor quality of healthcare parameters. Data on the number of hospitalizations and their cost were compared before and after implementation of the intervention program. Results As a result of the intervention the mean expenditure per elderly patient was reduced by 22.5%. The adjusted number of hospitalizations/1,000 declined from 15.1 to 10.7 (29.3%. The number of adjusted hospitalization days dropped from 132 to 82 (37.9% and the mean hospitalization stay declined from 8.2 to 6.7 days (17.9%. The adjusted hospitalization cost ($/1,000 patients dropped from $32,574 to $18,624 (42.8%. The overall clinic expense, for all age groups, dropped by 9.9%. Conclusion Implementation of the intervention program in a single primary care clinic led to a reduction in hospitalizations for the elderly patient population and to a more optimal allocation of healthcare resources.

  11. National Ambulatory Medical Care Survey: tobacco intervention practices in outpatient clinics. (United States)

    Payne, Thomas J; Chen, Chieh-I; Baker, Christine L; Shah, Sonali N; Pashos, Chris L; Boulanger, Luke


    Tobacco use remains the leading cause of preventable death. The outpatient medical clinic represents an important venue for delivering evidence-based interventions to large numbers of tobacco users. Extensive evidence supports the effectiveness of brief interventions. In a retrospective database analysis of 11,827 adult patients captured in the 2005 National Ambulatory Medical Care Survey (of which 2,420 were tobacco users), we examined the degree to which a variety of patient demographic, clinical and physician-related variables predict the delivery of tobacco counseling during a routine outpatient visit in primary care settings. In 2005, 21.7% of identified tobacco users received a tobacco intervention during their visit. The probability of receiving an intervention differed by gender, geographic region and source of payment. Individuals presenting with tobacco-related health conditions were more likely to receive an intervention. Most physicians classified as specialists were less likely to intervene. The provision of tobacco intervention services appears to be increasing at a modest rate, but remains well below desirable levels. It is a priority that brief interventions be routinely implemented to reduce the societal burden of tobacco use.

  12. Development of clinically meaningful complex interventions - the contribution of qualitative research. (United States)

    Ludvigsen, Mette Spliid; Meyer, Gabriele; Hall, Elisabeth; Fegran, Liv; Aagaard, Hanne; Uhrenfeldt, Lisbeth


    The debate about the "right" methods and designs for nursing research is on-going. According to international surveys, studies on the effectiveness and safety of nursing interventions are rare. Since nursing practice deals daily with interventions, nurses ostensibly expose hospital patients and nursing home residents frequently to unproven therapeutic and preventive nursing interventions. Nursing interventions are predominately of a complex nature, consisting of several components depending on and interacting with each other and their complex contextual factors. Thus, evaluation studies are often challenging and need especially careful development, ambitious designs and systematic evaluations. The UK Medical Research Council (MRC) has proposed a framework, where qualitative and quantitative research rely on each other in order to develop theory-based complex interventions, prepare and conduct their optimal delivery, explain how the interventions work and which conditions contributed in case they did not work. The present essay outlines the points where qualitative research contributes towards the development and evaluation of complex interventions. First, the UK MRC framework is introduced, and secondly it is illustrated where qualitative research should necessarily be located using examples from a handful of qualitative studies. Future clinically meaningful and implementable nursing interventions should best be developed by research groups with both excellent qualitative and quantitative research skills.

  13. Clinically Relevant Physical Benefits of Exercise Interventions in Breast Cancer Survivors. (United States)

    Kirkham, Amy A; Bland, Kelcey A; Sayyari, Sarah; Campbell, Kristin L; Davis, Margot K


    Evidence is currently limited for the effect of exercise on breast cancer clinical outcomes. However, several of the reported physical benefits of exercise, including peak oxygen consumption, functional capacity, muscle strength and lean mass, cardiovascular risk factors, and bone health, have established associations with disability, cardiovascular disease risk, morbidity, and mortality. This review will summarize the clinically relevant physical benefits of exercise interventions in breast cancer survivors and discuss recommendations for achieving these benefits. It will also describe potential differences in intervention delivery that may impact outcomes and, lastly, describe current physical activity guidelines for cancer survivors.

  14. Bibliometric Analysis: Mirror Therapy as an Occupational Therapy Intervention Strategy in the Clinical Setting

    Directory of Open Access Journals (Sweden)

    Elvis Siprián Castro Alzate


    Full Text Available Objective: To determine the national and international scientific evidence regarding the use of mirror therapy, as an occupational therapy intervention tool in the clinical setting, in order to acquire knowledge and implement this strategy in professional practice. Materials and methods: A descriptive study was conducted in which the research strategy was held through medical subject headings (MeSH, such as “mirror neuron”, ”occupational therapy”, “physical rehabilitation” and “motor imagery”. Through the use of the bolean and combinations in five different databases were performed: Embase, Ebsco, OTseeker, Science Direct and Medline. The analysis was elaborated by establishing frequencies of different variables such as journal, country, study type and publish­ing year. Conclusions: In the evidence analysis it was found that mirror therapy is an interven­tion modality recently used by different rehabilitation professionals. Since 2004, an increase in the generation of high impact scientific evidence about this subject has been recognized, due in part to the reported effectiveness in clinical practices, mainly the treatment of health conditions secondary to stroke, limb amputations, chronic pain syndromes, and post-surgical rehabilitation. During the reviewed period, an increase in high level academic evidence was observed: 35.7 % of the analyzed publications correspond to randomized controlled trials and 42.9 % are system­atic reviews. The use of mirror therapy in occupational therapy is an intervention modality that facilitates functional rehabilitation processes, promotes independence in performing activities of daily living (adl and allows social participation and environment adaptation processes to happen.

  15. Extracellular vesicles: masters of intercellular communication and potential clinical interventions. (United States)

    Pitt, Jonathan M; Kroemer, Guido; Zitvogel, Laurence


    Intercellular signaling via extracellular vesicles (EVs) is an underappreciated modality of cell-cell crosstalk that enables cells to convey packages of complex instructions to specific recipient cells. EVs transmit these instructions through their cargoes of multiple proteins, nucleic acids, and specialized lipids, which are derived from their cells of origin and allow for combinatorial effects upon recipient cells. This Review series brings together the recent progress in our understanding of EV signaling in physiological and pathophysiological conditions, highlighting how certain EVs, particularly exosomes, can promote or regulate infections, host immune responses, development, and various diseases - notably cancer. Given the diverse nature of EVs and their abilities to profoundly modulate host cells, this series puts particular emphasis on the clinical applications of EVs as therapeutics and as diagnostic biomarkers.

  16. Improving Decision Making about Genetic Testing in the Clinic: An Overview of Effective Knowledge Translation Interventions (United States)

    Légaré, France; Robitaille, Hubert; Gane, Claire; Hébert, Jessica; Labrecque, Michel; Rousseau, François


    Background Knowledge translation (KT) interventions are attempts to change behavior in keeping with scientific evidence. While genetic tests are increasingly available to healthcare consumers in the clinic, evidence about their benefits is unclear and decisions about genetic testing are thus difficult for all parties. Objective We sought to identify KT interventions that involved decisions about genetic testing in the clinical context and to assess their effectiveness for improving decision making in terms of behavior change, increased knowledge and wellbeing. Methods We searched for trials assessing KT interventions in the context of genetic testing up to March 2014 in all systematic reviews (n = 153) published by two Cochrane review groups: Effective Practice and Organisation of Care (EPOC) and Consumers and Communication. Results We retrieved 2473 unique trials of which we retained only 28 (1%). Two EPOC reviews yielded two trials of KT interventions: audit and feedback (n = 1) and educational outreach (n = 1). Both targeted health professionals and the KT intervention they assessed was found to be effective. Four Consumers and Communication reviews yielded 26 trials: decision aids (n = 15), communication of DNA-based disease risk estimates (n = 7), personalized risk communication (n = 3) and mobile phone messaging (n = 1). Among these, 25 trials targeted only health consumers or patients and the KT interventions were found to be effective in four trials, partly effective in seven, and ineffective in four. Lastly, only one trial targeted both physicians and patients and was found to be effective. Conclusions More research on the effectiveness of KT interventions regarding genetic testing in the clinical context may contribute to patients making informed value-based decisions and drawing the maximum benefit from clinical applications of genetic and genomic innovations.

    Full Text Available Knowledge translation (KT interventions are attempts to change behavior in keeping with scientific evidence. While genetic tests are increasingly available to healthcare consumers in the clinic, evidence about their benefits is unclear and decisions about genetic testing are thus difficult for all parties.We sought to identify KT interventions that involved decisions about genetic testing in the clinical context and to assess their effectiveness for improving decision making in terms of behavior change, increased knowledge and wellbeing.We searched for trials assessing KT interventions in the context of genetic testing up to March 2014 in all systematic reviews (n = 153 published by two Cochrane review groups: Effective Practice and Organisation of Care (EPOC and Consumers and Communication.We retrieved 2473 unique trials of which we retained only 28 (1%.

  18. What's the Point?: A Review of Reward Systems Implemented in Gamification Interventions. (United States)

    Lewis, Zakkoyya H; Swartz, Maria C; Lyons, Elizabeth J


    Rewards are commonly used in interventions to change behavior, but they can inhibit development of intrinsic motivation, which is associated with long-term behavior maintenance. Gamification is a novel intervention strategy that may target intrinsic motivation through fun and enjoyment. Before the effects of gamified interventions on motivation can be determined, there must be an understanding of how gamified interventions operationalize rewards, such as point systems. The purpose of this review is to determine the prevalence of different reward types, specifically point systems, within gamified interventions. Electronic databases were searched for relevant articles. Data sources included Medline OVID, Medline PubMed, Web of Science, CINAHL, Cochrane Central, and PsycINFO. Out of the 21 articles retrieved, 18 studies described a reward system and were included in this review. Gamified interventions were designed to target a myriad of clinical outcomes across diverse populations. Rewards included points (n = 14), achievements/badges/medals (n = 7), tangible rewards (n = 7), currency (n = 4), other unspecified rewards (n = 3), likes (n = 2), animated feedback (n = 1), and kudos (n = 1). Rewards, and points in particular, appear to be a foundational component of gamified interventions. Despite their prevalence, authors seldom described the use of noncontingent rewards or how the rewards interacted with other game features. The reward systems relying on tangible rewards and currency may have been limited by inhibited intrinsic motivation. As gamification proliferates, future research should explicitly describe how rewards were operationalized in the intervention and evaluate the effects of gamified rewards on motivation across populations and research outcomes.

  19. Development of a Web-Based Clinical Decision Support System for Drug Prescription: Non-Interventional Naturalistic Description of the Antipsychotic Prescription Patterns in 4345 Outpatients and Future Applications (United States)

    Berrouiguet, Sofian; Barrigón, Maria Luisa; Brandt, Sara A.; Ovejero-García, Santiago; Álvarez-García, Raquel; Carballo, Juan Jose; Lenca, Philippe; Courtet, Philippe; Baca-García, Enrique


    Purpose The emergence of electronic prescribing devices with clinical decision support systems (CDSS) is able to significantly improve management pharmacological treatments. We developed a web application available on smartphones in order to help clinicians monitor prescription and further propose CDSS. Method A web application ( was developed to assess patients and collect data regarding gender, age, diagnosis and treatment. We analyzed antipsychotic prescriptions in 4345 patients attended in five Psychiatric Community Mental Health Centers from June 2014 to October 2014. The web-application reported average daily dose prescribed for antipsychotics, prescribed daily dose (PDD), and the PDD to defined daily dose (DDD) ratio. Results The MEmind web-application reported that antipsychotics were used in 1116 patients out of the total sample, mostly in 486 (44%) patients with schizophrenia related disorders but also in other diagnoses. Second generation antipsychotics (quetiapine, aripiprazole and long-acting paliperidone) were preferably employed. Low doses were more frequently used than high doses. Long acting paliperidone and ziprasidone however, were the only two antipsychotics used at excessive dosing. Antipsychotic polypharmacy was used in 287 (26%) patients with classic depot drugs, clotiapine, amisulpride and clozapine. Conclusions In this study we describe the first step of the development of a web application that is able to make polypharmacy, high dose usage and off label usage of antipsychotics visible to clinicians. Current development of the MEmind web application may help to improve prescription security via momentary feedback of prescription and clinical decision support system. PMID:27764107

    Full Text Available Abstract Background To determine factors that predict adherence to a mind-body intervention in a randomized trial. Design We analyzed adherence data from a 3-arm trial involving 135 generally healthy seniors 65–85 years of age randomized to a 6-month intervention consisting of: an Iyengar yoga class with home practice, an exercise class with home practice, or a wait-list control group. Outcome measures included cognitive function, mood, fatigue, anxiety, health-related quality of life, and physical measures. Adherence to the intervention was obtained by class attendance and biweekly home practice logs. Results The drop-out rate was 13%. Among the completers of the two active interventions, average yoga class attendance was 77% and home practice occurred 64% of all days. Average exercise class attendance was 69% and home exercise occurred 54% of all days. There were no clear effects of adherence on the significant study outcomes (quality of life and physical measures. Class attendance was significantly correlated with baseline measures of depression, fatigue, and physical components of health-related quality of life. Significant differences in baseline measures were also found between study completers and drop-outs in the active interventions. Adherence was not related to age, gender, or education level. Conclusion Healthy seniors have good attendance at classes with a physically active intervention. Home practice takes place over half of the time. Decreased adherence to a potentially beneficial intervention has the potential to decrease the effect of the intervention in a clinical trial because subjects who might sustain the greatest benefit will receive a lower dose of the intervention and subjects with higher adherence rates may be functioning closer to maximum ability before the intervention. Strategies to maximize adherence among subjects at greater risk for low adherence will be important for future trials, especially complementary

  1. A decision support system for AIDS intervention and prevention. (United States)

    Xu, L D


    In recent years, the importance of information systems has been identified as a vital issue to continuing success in AIDS intervention and prevention (AIP). The advances in information technology have resulted in integrative information systems including decision support systems (DSS). The concept of DSS for AIP was created at the intersection of two trends. The first trend was a growing belief that AIP information systems are successful in automating operations in AIP programs. The second was a continuing improvement in modeling and software development in the AIP area. This paper presents an integrated DSS for AIP. The system is integrated with a database and achieves its efficiency by incorporating various algorithms and models to support AIP decision processes. The application examples include screening AIDS-risky behaviors, evaluating educational interventions, and scheduling AIP sessions. The implementation results present evidence of the usefulness of the system in AIP.

    Zhang, Jing; Luo, Rong; Chen, Shi; Petrovic, Djordje; Redfern, Julie; Xu, Dong Roman; Patel, Anushka


    Background With rapidly expanding infrastructure in China, mobile technology has been deemed to have the potential to revolutionize health care delivery. There is particular promise for mobile health (mHealth) to positively influence health system reform and confront the new challenges of chronic diseases. Objective The aim of this study was to systematically review existing mHealth initiatives in China, characterize them, and examine the extent to which mHealth contributes toward the health system strengthening in China. Furthermore, we also aimed to identify gaps in mHealth development and evaluation. Methods We systematically reviewed the literature from English and Chinese electronic database and trial registries, including PubMed, EMBASE, Cochrane, China National Knowledge of Infrastructure (CNKI), and World Health Organization (WHO) International Clinical Trials Registry Platform. We used the English keywords of mHealth, eHealth, telemedicine, telehealth, mobile phone, cell phone, text messaging, and China, as well as their corresponding Chinese keywords. All articles using mobile technology for health care management were included in the study. Results A total of 1704 articles were found using the search terms, and eventually 72 were included. Overall, few high quality interventions were identified. Most interventions were found to be insufficient in scope, and their evaluation was of inadequate rigor to generate scalable solutions and provide reliable evidence of effectiveness. Most interventions focused on text messaging for consumer education and behavior change. There were a limited number of interventions that addressed health information management, health workforce issues, use of medicines and technologies, or leadership and governance from a health system perspective. Conclusions We provide four recommendations for future mHealth interventions in China that include the need for the development, evaluation and trials examining integrated m

  3. Endoscopic vs. Surgical Interventions for Painful Chronic Pancreatitis: What is Needed for Future Clinical Trials (United States)

    Windsor, John A; Reddy, Nageshwar D


    The treatment of painful chronic pancreatitis remains controversial. The available evidence from two randomized controlled trials favor surgical intervention, whereas an endotherapy-first approach is widely practiced. Chronic pancreatitis is complex disease with different genetic and environmental factors, different pain mechanisms and different treatment modalities including medical, endoscopic, and surgical. The widely practiced step-up approach remains unproven. In designing future clinical trials there are some important pre-requisites including a more comprehensive pain assessment tool, the optimization of conservative medical treatment and interventional techniques. Consideration should be given to the need of a control arm and the optimal timing of intervention. Pending better designed studies, the practical way forward is to identify subgroups of patients who clearly warrant endotherapy or surgery first, and to design the future clinical trials for the remainder.

  5. The impact of IPTi and IPTc interventions on malaria clinical burden - in silico perspectives.

    Directory of Open Access Journals (Sweden)

    Ricardo Aguas

    Full Text Available BACKGROUND: Clinical management of malaria is a major health issue in sub-Saharan Africa. New strategies based on intermittent preventive treatment (IPT can tackle disease burden by simultaneously reducing frequency of infections and life-threatening illness in infants (IPTi and children (IPTc, while allowing for immunity to build up. However, concerns as to whether immunity develops efficiently in treated individuals, and whether there is a rebound effect after treatment is halted, have made it imperative to define the effects that IPTi and IPTc exert on the clinical malaria scenario. METHODS AND FINDINGS: Here, we simulate several schemes of intervention under different transmission settings, while varying immunity build up assumptions. Our model predicts that infection risk and effectiveness of acquisition of clinical immunity under prophylactic effect are associated to intervention impact during treatment and follow-up periods. These effects vary across regions of different endemicity and are highly correlated with the interplay between the timing of interventions in age and the age dependent risk of acquiring an infection. However, even when significant rebound effects are predicted to occur, the overall intervention impact is positive. CONCLUSIONS: IPTi is predicted to have minimal impact on the acquisition of clinical immunity, since it does not interfere with the occurrence of mild infections, thus failing to reduce the underlying force of infection. On the contrary, IPTc has a significant potential to reduce transmission, specifically in areas where it is already low to moderate.

  14. Investigating combination HIV prevention: isolated interventions or complex system

    Directory of Open Access Journals (Sweden)

    Graham Brown


    Full Text Available Introduction: Treatment as prevention has mobilized new opportunities in preventing HIV transmission and has led to bold new UNAIDS targets in testing, treatment coverage and transmission reduction. These will require not only an increase in investment but also a deeper understanding of the dynamics of combining behavioural, biomedical and structural HIV prevention interventions. High-income countries are making substantial investments in combination HIV prevention, but is this investment leading to a deeper understanding of how to combine interventions? The combining of interventions involves complexity, with many strategies interacting with non-linear and multiplying rather than additive effects. Discussion: Drawing on a recent scoping study of the published research evidence in HIV prevention in high-income countries, this paper argues that there is a gap between the evidence currently available and the evidence needed to guide the achieving of these bold targets. The emphasis of HIV prevention intervention research continues to look at one intervention at a time in isolation from its interactions with other interventions, the community and the socio-political context of their implementation. To understand and evaluate the role of a combination of interventions, we need to understand not only what works, but in what circumstances, what role the parts need to play in their relationship with each other, when the combination needs to adapt and identify emergent effects of any resulting synergies. There is little development of evidence-based indicators on how interventions in combination should achieve that strategic advantage and synergy. This commentary discusses the implications of this ongoing situation for future research and the required investment in partnership. We suggest that systems science approaches, which are being increasingly applied in other areas of public health, could provide an expanded vocabulary and analytic tools for

    Full Text Available Intervention planning is crucial for maintenance operations in particle accelerator environments with ionizing radiation, during which the radiation dose received by maintenance workers should be reduced to a minimum. In this context, we discuss the development of a new software tool and the entailed methodology, including the visualization aspects. The software tool integrates interactive exploration of a scene depicting an accelerator facility augmented with residual radiation level simulations, with the visualization of intervention data such as the followed trajectory and maintenance tasks. Its conception allows for future inclusion of measurements performed by mobile robotic devices. In this work, we explore the systems engineering life cycle of the development process of an interactive intervention planner, which includes the needs analysis, specification explicitation, conceptual mathematical modelling, iterative implementation, design and prototype testing and usability testing.

    Kwon, Kyoung Ah; Chun, Peter


    Purpose This study aimed to investigate the clinical significance of serum alanine aminotransferase (ALT) levels in children with nonalcoholic fatty liver disease (NAFLD) and the effect of lifestyle intervention on NAFLD. Methods The clinical data of 86 children diagnosed with NAFLD were reviewed retrospectively. Forty-six patients belonged to the elevated ALT group and 40 to the normal ALT group. The clinical parameters of patients with NAFLD were also compared based on the status of ALT levels after lifestyle intervention. Results Patients with elevated ALT had significantly higher body mass index (BMI) scores than those with normal ALT (P<0.05). Of all the patients with elevated ALT, 89% exhibited moderate or severe degree of fatty change in the liver on ultrasonographic examination, whereas most patients with normal ALT exhibited mild or moderate degree changes. Liver biopsy was performed in 15 children with elevated ALT and all showed mild histological changes. Of all patients with elevated ALT, 49% achieved normal ALT levels after lifestyle intervention. Those with more severe histological changes tended to have continuously increasing ALT levels. There was no correlation between the normalization of posttreatment ALT level and BMI, as well as ultrasonographic findings at diagnosis. Conclusion ALT elevation in NAFLD is highly associated with higher BMI scores and more severe degree of fatty changes on ultrasonographic examination. Lifestyle intervention can significantly improve ALT in children with NAFLD. The degree of histologic changes appears to be a predictor of the treatment response to NAFLD.

  20. Measures of clinical malaria in field trials of interventions against Plasmodium falciparum

    Smith Thomas A


    Full Text Available Abstract Background Standard methods for defining clinical malaria in intervention trials in endemic areas do not guarantee that efficacy estimates will be unbiased, and do not indicate whether the intervention has its effect by modifying the force of infection, the parasite density, or the risk of pathology at given parasite density. Methods Three different sets, each of 500 Phase IIb or III malaria vaccine trials were simulated corresponding to each of a pre-erythrocytic, blood stage, and anti-disease vaccine, each in a population with 80% prevalence of patent malaria infection. Simulations considered only the primary effects of vaccination in a homogeneous trial population. The relationships between morbidity and parasite density and the performance of different case definitions for clinical malaria were analysed using conventional likelihood ratio tests to compare incidence of episodes defined using parasite density cut-offs. Bayesian latent class models were used to compare the overall frequencies of clinical malaria episodes in analyses that did not use diagnostic cut-offs. Results The different simulated interventions led to different relationships between clinical symptoms and parasite densities. Consequently, the operating characteristics of parasitaemia cut-offs in general differ between vaccine and placebo arms of the simulated trials, leading to different patterns of bias in efficacy estimates depending on the type of intervention effect. Efficacy was underestimated when low parasitaemia cut-offs were used but the efficacy of an asexual blood stage vaccine was overestimated when a high parasitaemia cut-off was used. The power of a trial may be maximal using case definitions that are associated with substantial bias in efficacy. Conclusion Secondary analyses of the data of malaria intervention trials should consider the relationship between clinical symptoms and parasite density, and attempt to estimate overall numbers of clinical

    Gross, Douglas P; Armijo-Olivo, Susan; Shaw, William S; Williams-Whitt, Kelly; Shaw, Nicola T; Hartvigsen, Jan; Qin, Ziling; Ha, Christine; Woodhouse, Linda J; Steenstra, Ivan A


    Purpose We aimed to identify and inventory clinical decision support (CDS) tools for helping front-line staff select interventions for patients with musculoskeletal (MSK) disorders. Methods We used Arksey and O'Malley's scoping review framework which progresses through five stages: (1) identifying the research question; (2) identifying relevant studies; (3) selecting studies for analysis; (4) charting the data; and (5) collating, summarizing and reporting results. We considered computer-based, and other available tools, such as algorithms, care pathways, rules and models. Since this research crosses multiple disciplines, we searched health care, computing science and business databases. Results Our search resulted in 4605 manuscripts. Titles and abstracts were screened for relevance. The reliability of the screening process was high with an average percentage of agreement of 92.3 %. Of the located articles, 123 were considered relevant. Within this literature, there were 43 CDS tools located. These were classified into 3 main areas: computer-based tools/questionnaires (n = 8, 19 %), treatment algorithms/models (n = 14, 33 %), and clinical prediction rules/classification systems (n = 21, 49 %). Each of these areas and the associated evidence are described. The state of evidentiary support for CDS tools is still preliminary and lacks external validation, head-to-head comparisons, or evidence of generalizability across different populations and settings. Conclusions CDS tools, especially those employing rapidly advancing computer technologies, are under development and of potential interest to health care providers, case management organizations and funders of care. Based on the results of this scoping review, we conclude that these tools, models and systems should be subjected to further validation before they can be recommended for large-scale implementation for managing patients with MSK disorders.

  5. Development, Implementation, and Evaluation of a Pilot Parenting Educational Intervention in a Pregnancy Buprenorphine Clinic. (United States)

    Giles, Averie C; Ren, Dianxu; Founds, Sandra


    We developed a pilot evidence-based prenatal educational intervention to increase knowledge of neonatal abstinence syndrome (NAS) and early parenting skills for women with opiate dependency who enrolled in a pregnancy buprenorphine clinic. We developed, implemented, and tested modules regarding expectations during newborn hospitalization for observation or treatment of NAS and regarding evidence-based parenting skills in response to NAS behaviors. Testing evaluated baseline knowledge of early parenting skills with newborns at risk for NAS and change from baseline after the educational intervention. No statistically significant difference in composite knowledge scores was observed. A brief survey completed by the participants postpartum affirmed the perception of women that the educational intervention effectively prepared them for the early postpartum period while their newborns were hospitalized.

  7. Clinical trials in Huntington's disease: Interventions in early clinical development and newer methodological approaches. (United States)

    Sampaio, Cristina; Borowsky, Beth; Reilmann, Ralf


    Since the identification of the Huntington's disease (HD) gene, knowledge has accumulated about mechanisms directly or indirectly affected by the mutated Huntingtin protein. Transgenic and knock-in animal models of HD facilitate the preclinical evaluation of these targets. Several treatment approaches with varying, but growing, preclinical evidence have been translated into clinical trials. We review major landmarks in clinical development and report on the main clinical trials that are ongoing or have been recently completed. We also review clinical trial settings and designs that influence drug-development decisions, particularly given that HD is an orphan disease. In addition, we provide a critical analysis of the evolution of the methodology of HD clinical trials to identify trends toward new processes and endpoints. Biomarker studies, such as TRACK-HD and PREDICT-HD, have generated evidence for the potential usefulness of novel outcome measures for HD clinical trials, such as volumetric imaging, quantitative motor (Q-Motor) measures, and novel cognitive endpoints. All of these endpoints are currently applied in ongoing clinical trials, which will provide insight into their reliability, sensitivity, and validity, and their use may expedite proof-of-concept studies. We also outline the specific opportunities that could provide a framework for a successful avenue toward identifying and efficiently testing and translating novel mechanisms of action in the HD field.

    Dani Laura Peruzzolo


    Full Text Available Introduction: Specialized care for infants considers that the sooner the intervention in risk and symptoms occurs, the greater the possibility of obtaining better results. Aims: To describe the process of early intervention provided by an extension program of graduate studies in Occupational Therapy and Hearing, Speech and Languages Science courses and also discuss the theoretical and practical paths in the care for infants and in the Occupational Therapy area. Method: Case report with convenience sample. The study was carried out through an assessment interpreted in light of psychomotor, occupational therapeutic, and speech, hearing and language contributions. The intervention was under the responsibility of an occupational therapist supported by an interdisciplinary team. It occurred once a week from August 2011 to January 2012 and from March 2012 to July 2012. Data analysis was carried out by comparing the entry assessment test and the final assessment test. Results: The boy had not developed concepts of body schema and body image that could sustain his relationship with objects, space and other persons. He presented little linguistic evolution. Considering the contributions of occupational therapy in psychomotor clinic, the boy reconstructed his family place in early intervention. The possibility of language functioning connected to the boy’s demands allowed access to symbolism. Conclusion: The proposal of early occupational therapy intervention with a single therapist supported by an interdisciplinary team was able to overcome the structural and instrumental obstacles to the boy’s development.

  11. OARSI Clinical Trials Recommendations: Design and conduct of clinical trials of rehabilitation interventions for osteoarthritis. (United States)

    Fitzgerald, G K; Hinman, R S; Zeni, J; Risberg, M A; Snyder-Mackler, L; Bennell, K L


    A Task Force of the Osteoarthritis Research Society International (OARSI) has previously published a set of guidelines for the conduct of clinical trials in osteoarthritis (OA) of the hip and knee. Limited material available on clinical trials of rehabilitation in people with OA has prompted OARSI to establish a separate Task Force to elaborate guidelines encompassing special issues relating to rehabilitation of OA. The Task Force identified three main categories of rehabilitation clinical trials. The categories included non-operative rehabilitation trials, post-operative rehabilitation trials, and trials examining the effectiveness of devices (e.g., assistive devices, bracing, physical agents, electrical stimulation, etc.) that are used in rehabilitation of people with OA. In addition, the Task Force identified two main categories of outcomes in rehabilitation clinical trials, which include outcomes related to symptoms and function, and outcomes related to disease modification. The guidelines for rehabilitation clinical trials provided in this report encompass these main categories. The report provides guidelines for conducting and reporting on randomized clinical trials. The topics include considerations for entering patients into trials, issues related to conducting trials, considerations for selecting outcome measures, and recommendations for statistical analyses and reporting of results. The focus of the report is on rehabilitation trials for hip, knee and hand OA, however, we believe the content is broad enough that it could be applied to rehabilitation trials for other regions as well.

  12. Is diagnosis enough to guide interventions in mental health? Using case formulation in clinical practice

    Directory of Open Access Journals (Sweden)

    Macneil Craig A


    Full Text Available Abstract While diagnosis has traditionally been viewed as an essential concept in medicine, particularly when selecting treatments, we suggest that the use of diagnosis alone may be limited, particularly within mental health. The concept of clinical case formulation advocates for collaboratively working with patients to identify idiosyncratic aspects of their presentation and select interventions on this basis. Identifying individualized contributing factors, and how these could influence the person's presentation, in addition to attending to personal strengths, may allow the clinician a deeper understanding of a patient, result in a more personalized treatment approach, and potentially provide a better clinical outcome.

    pressure 24 h patterns (nocturnal hypertension); delayed sleep phase syndrome, non-24 h sleep/wake disorder; recurrent hypersomnia; SW intolerance; delirium; peptic ulcer disease; kidney failure; depression; mania; bipolar disorder; Parkinson's disease; Smith-Magenis syndrome; fatal familial insomnia syndrome; autism spectrum disorder; asthma; byssinosis; cancers; hand, foot and mouth disease; post-operative state; and ICU outcome. Poorly conceived medical interventions, for example nighttime dosing of synthetic corticosteroids and certain β-antagonists and cyclic nocturnal enteral or parenteral nutrition, plus lifestyle habits, including atypical eating times and chronic alcohol consumption, also can be causal of CD. Just as surprisingly are the many proven chronotherapeutic strategies available today to manage the CD of several of these medical conditions. In clinical medicine, CD seems to be a common, yet mostly unrecognized, pathologic mechanism of human disease as are the many effective chronotherapeutic interventions to remedy it.

  14. [Clinical and preventive intervention in eating behaviour: a dialogue between psychology and nutritional sciences]. (United States)

    Tinoco, Rui; Paiva, Isabel


    The eating habits modification is a clinical challenge, both on therapeutic and preventive levels, which requires tools from various areas of health, such as psychology and nutrition. In the structured work in these areas, that includes the referral to specialist consultants, there is a need of a first intervention in Primary Health Care, in clinical and community levels. In this paper, we attempt to systematize useful information for intervention. We will start by reviewing some important interviewing skills, some models of motivational interviewing, and we will make a brief reflection about the client. Then we will analyse an individual case structured in two complementary levels of interpretation: a closer look in general factors and another that reflect the antecedents, consequences and the description of the behaviour problem. We will also tackle issues related to the context in which the individual moves. We will analyse some group intervention programs within a clinical and preventive perspectives. Finally, we will discuss some concepts related to therapeutic adherence.

  15. Relation of metformin treatment to clinical events in diabetic patients undergoing percutaneous intervention. (United States)

    Kao, John; Tobis, Jonathan; McClelland, Robyn L; Heaton, Melissa R; Davis, Barry R; Holmes, David R; Currier, Jesse W


    Diabetic patients undergoing coronary interventions have worse clinical and angiographic outcomes than do patients without diabetes. Metformin, an insulin sensitizer, may decrease the occurrence of these outcomes. Diabetic patients in the Prevention of Restenosis with Tranilast and its Outcomes Trial were identified through their medical records (n = 2,772). In this trial, 1,110 diabetic patients received nonsensitizer therapy (insulin and/or sulfonylureas) and 887 received sensitizer therapy (metformin with or without additional therapy). Logistic regression was used to obtain odds ratios (ORs) (sensitizer vs nonsensitizer therapy) of any clinical event (death, myocardial infarction, or ischemia-driven target vessel revascularization) and adjusted for multiple risk factors. Multivariate analysis showed no effect of lesion characteristics on clinical outcomes. Compared with patients on nonsensitizer therapy, those on sensitizer therapy showed an adjusted OR of 0.72 (95% confidence interval [CI] 0.57 to 0.91, p = 0.005) for any clinical event. The differences between the nonsensitizer therapy group and the sensitizer group were attributable mainly to decreased rates of death (OR 0.39, 95% CI 0.19 to 0.77, p = 0.007) and myocardial infarction (OR 0.31, 95% CI 0.15 to 0.66, p = 0.002). In our retrospective analysis, use of metformin in diabetics undergoing coronary interventions appeared to decrease adverse clinical events, especially death and myocardial infarction, compared with diabetic patients treated with nonsensitizer therapy.

    Full Text Available In this paper we discuss positive clinical psychology as an emerging field within clinical psychology. Positive clinical psychology is based on research demonstrating that mental health is more than the absence of mental illness, on research showing that wellbeing has buffering effects on the incidence of psychopathology and mental illnesses and on studies demonstrating that positive characteristics, such as positive emotions and gratitude, can predict pathology beyond the predictive power of negative characteristics. In this paper we present three distinct forms of well-being: emotional, psychological and social. In addition we review three types of positive clinical interventions: well-being therapy, positive psychotherapy and acceptance and commitment therapy. The paper ends with a call for a transformation of mental health care in which illness oriented treatments are complemented with well-being oriented treatments.

  17. Behavioural and developmental interventions for autism spectrum disorder: a clinical systematic review.

    Directory of Open Access Journals (Sweden)

    Maria B Ospina

    Full Text Available BACKGROUND: Much controversy exists regarding the clinical efficacy of behavioural and developmental interventions for improving the core symptoms of autism spectrum disorders (ASD. We conducted a systematic review to summarize the evidence on the effectiveness of behavioural and developmental interventions for ASD. METHODS AND FINDINGS: Comprehensive searches were conducted in 22 electronic databases through May 2007. Further information was obtained through hand searching journals, searching reference lists, databases of theses and dissertations, and contacting experts in the field. Experimental and observational analytic studies were included if they were written in English and reported the efficacy of any behavioural or developmental intervention for individuals with ASD. Two independent reviewers made the final study selection, extracted data, and reached consensus on study quality. Results were summarized descriptively and, where possible, meta-analyses of the study results were conducted. One-hundred-and-one studies at predominantly high risk of bias that reported inconsistent results across various interventions were included in the review. Meta-analyses of three controlled clinical trials showed that Lovaas treatment was superior to special education on measures of adaptive behaviour, communication and interaction, comprehensive language, daily living skills, expressive language, overall intellectual functioning and socialization. High-intensity Lovaas was superior to low-intensity Lovaas on measures of intellectual functioning in two retrospective cohort studies. Pooling the results of two randomized controlled trials favoured developmental approaches based on initiative interaction compared to contingency interaction in the amount of time spent in stereotyped behaviours and distal social behaviour, but the effect sizes were not clinically significant. No statistically significant differences were found for: Lovaas versus special

    Full Text Available To investigate whether carrying out various interventions part way through the day influences comfort in symptomatic daily disposable (DD contact lens wearers.A subject-masked, randomized, controlled clinical trial was conducted in thirty symptomatic soft lens wearers who wore their habitual DD contact lenses bilaterally for 12 h on two separate days. Five hours after lens application, one of the following three interventions or a control was performed on each eye: replacing the existing lens with a new lens; removing and reapplying the same lens; performing a 'scleral swish'; and no action (control. Comfort scores were recorded using SMS text messages every hour following lens application using a 0 (causes pain to 100 (excellent comfort scale. Comfort scores before lens application, at 6 mins post-application, and at 6 mins post-intervention were also recorded.There was a significant reduction in comfort from pre-lens application to 6 mins post-application for all groups (all p0.05. After the intervention, comfort continued to decline (p<0.0001 with slightly lower mean scores for the control group compared to the new lens group (p = 0.003. Change in comfort relative to pre-intervention (5 h was similar for all groups (p = 0.81. There was no difference in comfort at 12 h between groups (p = 0.83.This work has confirmed that comfort shows a continual and significant decline over a 12-h wearing period in symptomatic DD contact lens wearers. None of the interventions investigated had any significant impact on end-of-day comfort. These data suggest discomfort in lens wearers is more heavily influenced by changes to the ocular environment rather than to the lens ISRCTN10419752

  19. Can teaching agenda-setting skills to physicians improve clinical interaction quality? A controlled intervention

    Directory of Open Access Journals (Sweden)

    Rogers William H


    Full Text Available Abstract Background Physicians and medical educators have repeatedly acknowledged the inadequacy of communication skills training in the medical school curriculum and opportunities to improve these skills in practice. This study of a controlled intervention evaluates the effect of teaching practicing physicians the skill of "agenda-setting" on patients' experiences with care. The agenda-setting intervention aimed to engage clinicians in the practice of initiating patient encounters by eliciting the full set of concerns from the patient's perspective and using that information to prioritize and negotiate which clinical issues should most appropriately be dealt with and which (if any should be deferred to a subsequent visit. Methods Ten physicians from a large physician organization in California with baseline patient survey scores below the statewide 25th percentile participated in the agenda-setting intervention. Eleven physicians matched on baseline scores, geography, specialty, and practice size were selected as controls. Changes in survey summary scores from pre- and post-intervention surveys were compared between the two groups. Multilevel regression models that accounted for the clustering of patients within physicians and controlled for respondent characteristics were used to examine the effect of the intervention on survey scale scores. Results There was statistically significant improvement in intervention physicians' ability to "explain things in a way that was easy to understand" (p = 0.02 and marginally significant improvement in the overall quality of physician-patient interactions (p = 0.08 compared to control group physicians. Changes in patients' experiences with organizational access, care coordination, and office staff interactions did not differ by experimental group. Conclusion A simple and modest behavioral training for practicing physicians has potential to positively affect physician-patient relationship interaction quality

    Full Text Available Abstract Background Guidelines recommend multifactorial intervention programmes to prevent falls in older adults but there are few randomised controlled trials in a real life health care setting. We describe the rationale, intervention, study design, recruitment strategies and baseline characteristics of participants in a randomised controlled trial of a multifactorial falls prevention programme in primary health care. Methods Participants are patients from 19 primary care practices in Hutt Valley, New Zealand aged 75 years and over who have fallen in the past year and live independently. Two recruitment strategies were used – waiting room screening and practice mail-out. Intervention participants receive a community based nurse assessment of falls and fracture risk factors, home hazards, referral to appropriate community interventions, and strength and balance exercise programme. Control participants receive usual care and social visits. Outcome measures include number of falls and injuries over 12 months, balance, strength, falls efficacy, activities of daily living, quality of life, and physical activity levels. Results 312 participants were recruited (69% women. Of those who had fallen, 58% of people screened in the practice waiting rooms and 40% when screened by practice letter were willing to participate. Characteristics of participants recruited using the two methods are similar (p > 0.05. Mean age of all participants was 81 years (SD 5. On average participants have 7 medical conditions, take 5.5 medications (29% on psychotropics with a median of 2 falls (interquartile range 1, 3 in the previous year.

  2. Childhood exposure to violence and lifelong health: Clinical intervention science and stress biology research join forces (United States)

    Moffitt, Terrie E.


    Many young people who are mistreated by an adult, victimized by bullies, criminally assaulted, or who witness domestic violence react to this violence exposure by developing behavioral, emotional, or learning problems. What is less well known is that adverse experiences like violence exposure can lead to hidden physical alterations inside a child’s body, alterations which may have adverse effects on life-long health. We discuss why this is important for the field of developmental psychopathology and for society, and we recommend that stress-biology research and intervention science join forces to tackle the problem. We examine the evidence base in relation to stress-sensitive measures for the body (inflammatory reactions, telomere erosion, epigenetic methylation, and gene expression) and brain (mental disorders, neuroimaging, and neuropsychological testing). We also review promising interventions for families, couples, and children that have been designed to reduce the effects of childhood violence exposure. We invite intervention scientists and stress-biology researchers to collaborate in adding stress-biology measures to randomized clinical trials of interventions intended to reduce effects of violence exposure and other traumas on young people.

  3. Moving from theory to research to practice. Implementing an effective dyadic intervention to improve antiretroviral adherence for clinic patients. (United States)

    Remien, Robert H; Stirratt, Michael J; Dognin, Joanna; Day, Emily; El-Bassel, Nabila; Warne, Patricia


    There is a dearth of evidence on the relative efficacy of intervention modalities to improve and maintain patient adherence to antiretroviral medications. Although empiric findings from research on HIV/AIDS, other diseases, and chronic medical conditions consistently demonstrate that social support plays an important role in facilitating adherence, few HIV/AIDS interventions have directly targeted this factor. Ewart's social action theory emphasizes the role of social relationships in behavior change and provides a comprehensive and useful guide to the development of interventions for adherence. We describe the development, content, and testing of SMART Couples, an effective antiretroviral adherence intervention that is grounded in social action theory and designed to enhance social support for ART adherence. Finally, we discuss some of the challenges of translating findings from the randomized clinical trial of this intervention into clinical practice and offer recommendations for integration of lessons learned into ongoing clinical care.

    Lightfoot, Marguerita; Rotheram-Borus, Mary Jane; Comulada, W Scott; Reddy, Vanessa S; Duan, Naihua


    Prevention of HIV transmission from patients living with HIV (PLH) is a high national priority and strategies that are easy to implement and sustain to eliminate sexual transmission acts among PLH are needed. We evaluated a brief intervention that focused primarily on the enhancing motivations and encouraging PLH to act in accordance with their values without providing the intensity of the existing evidence-based programs for PLH. Using a quasiexperimental design, six medical clinics in Los Angeles County, CA, were evaluated across three intervention conditions: 1) computerized delivery; 2) provider delivery; or 3) standard care. We examined longitudinal changes in patients' reports of the number of HIV-negative (HIV-) or serostatus-unknown sexual partners and the number of unprotected vaginal and anal sex acts. Among 566 PLH, PLH in the computerized delivery condition reported a significant decrease in the number of HIV-/unknown sexual partners compared with the provider delivery and standard care conditions and a significant decrease in the number of unprotected sex acts in comparison to the standard care condition. Computerized motivational interventions delivered in waiting rooms at medical clinics may be an efficient strategy to reduce unprotected sex acts among PLH.

    Kang, Ning; Afzal, Zubair; Singh, Bharat; Schuemie, Martijn J; van Mulligen, Erik M; Kors, Jan A


    Unstructured information comprises a valuable source of data in clinical records. For text mining in clinical records, concept extraction is the first step in finding assertions and relationships. This study presents a system developed for the annotation of medical concepts, including medical problems, tests, and treatments, mentioned in clinical records. The system combines six publicly available named entity recognition system into one framework, and uses a simple voting scheme that allows to tune precision and recall of the system to specific needs. The system provides both a web service interface and a UIMA interface which can be easily used by other systems. The system was tested in the fourth i2b2 challenge and achieved an F-score of 82.1% for the concept exact match task, a score which is among the top-ranking systems. To our knowledge, this is the first publicly available clinical record concept annotation system.

    Miller, Laurence


    Terrorist attacks combine features of a criminal assault, a mass casualty disaster and an act of war Accordingly, this article presents a model for prevention, response and recovery from the psychological impact of a terror attack. The nature of terrorism is delineated and the various psychological effects are described, including diagnostic clinical syndromes, as well as individual reactions. Interventions in the immediate aftermath of a terrorist attack include on-scene crisis intervention, short-term psychological stabilization, and longer-term psychotherapeutic approaches. Special techniques are described for individuals, families, children, and large groups of survivors and responders. Finally, the ways that mental health clinicians can serve as valuable consultants to community recovery efforts are discussed.

  11. The effect of systematic clinical interventions with cigarette smokers on quit status and the rates of smoking-related primary care office visits.

    Thomas G Land

    Full Text Available BACKGROUND: The United States Public Health Service (USPHS Guideline for Treating Tobacco Use and Dependence includes ten key recommendations regarding the identification and the treatment of tobacco users seen in all health care settings. To our knowledge, the impact of system-wide brief interventions with cigarette smokers on smoking prevalence and health care utilization has not been examined using patient population-based data. METHODS AND FINDINGS: Data on clinical interventions with cigarette smokers were examined for primary care office visits of 104,639 patients at 17 Harvard Vanguard Medical Associates (HVMA sites. An operational definition of "systems change" was developed. It included thresholds for intervention frequency and sustainability. Twelve sites met the criteria. Five did not. Decreases in self-reported smoking prevalence were 40% greater at sites that achieved systems change (13.6% vs. 9.7%, p<.01. On average, the likelihood of quitting increased by 2.6% (p<0.05, 95% CI: 0.1%-4.6% per occurrence of brief intervention. For patients with a recent history of current smoking whose home site experienced systems change, the likelihood of an office visit for smoking-related diagnoses decreased by 4.3% on an annualized basis after systems change occurred (p<0.05, 95% CI: 0.5%-8.1%. There was no change in the likelihood of an office visit for smoking-related diagnoses following systems change among non-smokers. CONCLUSIONS: The clinical practice data from HVMA suggest that a systems approach can lead to significant reductions in smoking prevalence and the rate of office visits for smoking-related diseases. Most comprehensive tobacco intervention strategies focus on the provider or the tobacco user, but these results argue that health systems should be included as an integral component of a comprehensive tobacco intervention strategy. The HVMA results also give us an indication of the potential health impacts when meaningful use core

    CERN Document Server

    Bennett, Casey C


    Purpose: This goal of this study was to evaluate the effects of a data-driven clinical productivity system that leverages Electronic Health Record (EHR) data to provide productivity decision support functionality in a real-world clinical setting. The system was implemented for a large behavioral health care provider seeing over 75,000 distinct clients a year. Design/methodology/approach: The key metric in this system is a "VPU", which simultaneously optimizes multiple aspects of clinical care. The resulting mathematical value of clinical productivity was hypothesized to tightly link the organization's performance to its expectations and, through transparency and decision support tools at the clinician level, affect significant changes in productivity, quality, and consistency relative to traditional models of clinical productivity. Findings: In only 3 months, every single variable integrated into the VPU system showed significant improvement, including a 30% rise in revenue, 10% rise in clinical percentage, a...

  13. Design and development of a mobile image overlay system for needle interventions. (United States)

    Anand, M; King, F; Ungi, T; Lasso, A; Rudan, J; Jayender, J; Fritz, J; Carrino, J A; Jolesz, F A; Fichtinger, G


    Previously, a static and adjustable image overlay systems were proposed for aiding needle interventions. The system was either fixed to a scanner or mounted over a large articulated counterbalanced arm. Certain drawbacks associated with these systems limited the clinical translation. In order to minimize these limitations, we present the mobile image overlay system with the objective of reduced system weight, smaller dimension, and increased tracking accuracy. The design study includes optimal workspace definition, selection of display device, mirror, and laser source. The laser plane alignment, phantom design, image overlay plane calibration, and system accuracy validation methods are discussed. The virtual image is generated by a tablet device and projected into the patient by using a beamsplitter mirror. The viewbox weight (1.0 kg) was reduced by 8.2 times and image overlay plane tracking precision (0.21 mm, STD = 0.05) was improved by 5 times compared to previous system. The automatic self-calibration of the image overlay plane was achieved in two simple steps and can be done away from patient table. The fiducial registration error of the physical phantom to scanned image volume registration was 1.35 mm (STD = 0.11). The reduced system weight and increased accuracy of optical tracking should enable the system to be hand held by the physician and explore the image volume over the patient for needle interventions.

  15. Screening, Brief Intervention, and Referral to Treatment in a rural Ryan White Part C HIV clinic. (United States)

    Graham, Lucy J; Davis, Amy L; Cook, Paul F; Weber, Mary


    About 24% of people living with HIV nationally are identified as needing treatment for alcohol or illicit drug use. Screening, Brief Intervention, and Referral to Treatment (SBIRT) has evolved as a strategy to assess and intervene with substance abuse behaviors in various clinical settings. However, less is known about the processes and outcomes of using the SBIRT intervention in outpatient HIV clinics. This paper presents a descriptive analysis of de-identified existing SBIRT results data from an outpatient HIV clinic located in western Colorado. From 2008 to 2013, a total of 1616 SBIRT evaluations were done, which included duplicate patients because some individual patients were screened more than once in a given year. Over this time period, 37-49% of encounters per year were notable for tobacco use, 8-21% for alcohol use, 6-16% for marijuana use, 3-9% for amphetamine use, and 0-2% for illicit opioid use. Unique, unduplicated patient data from 2013 revealed 40% of patients used tobacco, 16% used alcohol, and 11% used methamphetamine. Analyses highlighted that the majority of our patient population (58% in 2013) used and/or abused tobacco, alcohol, and/or illicit substances. An alarming finding was the increase in methamphetamine use over time with more than 50-fold prevalence of use in our population compared to national rates.

  16. Assessment of the occupational eye lens dose for clinical staff in interventional radiology, cardiology and neuroradiology. (United States)

    Omar, Artur; Kadesjö, Nils; Palmgren, Charlotta; Marteinsdottir, Maria; Segerdahl, Tony; Fransson, Annette


    In accordance with recommendations by the International Commission on Radiological Protection, the current European Basic Safety Standards has adopted a reduced occupational eye lens dose limit of 20 mSv yr(-1). The radiation safety implications of this dose limit is of concern for clinical staff that work with relatively high dose x-ray angiography and interventional radiology. Presented in this work is a thorough assessment of the occupational eye lens dose based on clinical measurements with active personal dosimeters worn by staff during various types of procedures in interventional radiology, cardiology and neuroradiology. Results are presented in terms of the estimated equivalent eye lens dose for various medical professions. In order to compare the risk of exceeding the regulatory annual eye lens dose limit for the widely different clinical situations investigated in this work, the different medical professions were separated into categories based on their distinct work pattern: staff that work (a) regularly beside the patient, (b) in proximity to the patient and (c) typically at a distance from the patient. The results demonstrate that the risk of exceeding the annual eye lens dose limit is of concern for staff category (a), i.e. mainly the primary radiologist/cardiologist. However, the results also demonstrate that the risk can be greatly mitigated if radiation protection shields are used in the clinical routine. The results presented in this work cover a wide range of clinical situations, and can be used as a first indication of the risk of exceeding the annual eye lens dose limit for staff at other medical centres.

    Background and Purpose As a result of the anatomical proximity of the thoracic spine to the cervical, lumbar, and shoulder regions, dysfunction in the thoracic spine can influence pain, mobility, and stability across these areas. Currently, a paucity of evidence exists addressing treatment of individuals with primary thoracic pain, especially in young, athletic patients. Furthermore, current research discussing clinical reasoning frameworks focus on the differential diagnostic process. The purpose of this case report was to present a framework that describes the clinical reasoning process for the implementation and sequencing of procedural interventions for the management of a dancer with thoracic pain. Case Description A 21-year-old female dancer presented to physical therapy with a medical diagnosis of thoracic pain. The patient reported exacerbation of left thoracic pain with prolonged sitting, twisting/arching her back during dance, and lifting >15 lbs overhead. Examination revealed hypomobility with positive pain provocation during mobility testing of T1-T3 and the sternocostal junction of ribs 2-4, with associated muscle guarding palpated in the left iliocostalis thoracis and levator scapulae. Outcomes Following 10 visits, the patient had no pain, no functional deficits, and a Global Rating of Change (GROC) of + 6. She returned to full competition, and a 3-month follow-up revealed continued success with dancing and a GROC of +7. Discussion This case report described the successful management of a dancer with primary thoracic pain using a clinical reasoning framework for the sequencing of procedural interventions, while incorporating Olson's impairment-based classification system. A combination of manual therapy techniques and neuromuscular control exercises were incorporated to address mobility, stability, mobility on stability, and skill level impairments, which allowed the patient to return to dance activities safely. Future studies should consider the

  18. Training-Based Interventions in Motor Rehabilitation after Stroke: Theoretical and Clinical Considerations

    Directory of Open Access Journals (Sweden)

    Annette Sterr


    Full Text Available Basic neuroscience research on brain plasticity, motor learning and recovery has stimulated new concepts in neurological rehabilitation. Combined with the development of set methodological standards in clinical outcome research, these findings have led to a double-paradigm shift in motor rehabilitation: (a the move towards evidence-based procedures for the assessment of clinical outcome & the employment of disablement models to anchor outcome parameters, and (b the introduction of practice-based concepts that are derived from testable models that specify treatment mechanisms. In this context, constraint-induced movement therapy (CIT has played a catalytic role in taking motor rehabilitation forward into the scientific arena. As a theoretically founded and hypothesis-driven intervention, CIT research focuses on two main issues. The first issue is the assessment of long-term clinical benefits in an increasing range of patient groups, and the second issue is the investigation of neuronal and behavioural treatment mechanisms and their interactive contribution to treatment success. These studies are mainly conducted in the research environment and will eventually lead to increased treatment benefits for patients in standard health care. However, gradual but presumably more immediate benefits for patients may be achieved by introducing and testing derivates of the CIT concept that are more compatible with current clinical practice. Here, we summarize the theoretical and empirical issues related to the translation of research-based CIT work into the clinical context of standard health care.

  19. Framework for a clinical information system. (United States)

    Van De Velde, R; Lansiers, R; Antonissen, G


    The design and implementation of Clinical Information System architecture is presented. This architecture has been developed and implemented based on components following a strong underlying conceptual and technological model. Common Object Request Broker and n-tier technology featuring centralised and departmental clinical information systems as the back-end store for all clinical data are used. Servers located in the "middle" tier apply the clinical (business) model and application rules. The main characteristics are the focus on modelling and reuse of both data and business logic. Scalability as well as adaptability to constantly changing requirements via component driven computing are the main reasons for that approach.

    This study aims to investigate the clinical significance of post-interventional cerebral hyperdensities (PCHD) after endovascular mechanical thrombectomy in acute ischaemic stroke. Data of 102 consecutive patients who received post-interventional CT scans within 4.5 h after mechanical thrombectomy were analysed retrospectively. Sixty-two of 102 patients (60.8 %) had PCHD on their post-interventional CT scans. The most common site of PCHD was the basal ganglia. PCHD were persisting in 13 of 62 patients (21.0 %), and transient in the remaining 49 patients (79.0 %) within 24 h. Four patients with PCHD and four patients without PCHD suffered from parenchymal haemorrhage. Neither ASA nor Clopidogrel, Tirofiban or rtPA were risk factors for PCHD. Final infarction size was congruent with or bigger than areas of PCHD in 93.3 % of cases in our series. PCHD was not a risk factor for parenchymal haemorrhage in our series. The occurrence of PCHD was strongly related to the prior presence of infarction. PCHD was also a strong predictor for final infarction size. (orig.)

    Objective:To explore the clinical efficacy of the early comprehensive intervention on hypoxic ischemic encephalopathy (HIE).Methods:HIE children who were admitted in our department from March, 2014 to May, 2015 were included in the study and randomized into the observation group and the control group. The patients in the control group were given routine fluid infusion, electrolyte disturbance correcting, blood sugar maintaining, convulsion controlling, intracranial pressure reducing, hormone, mannitol, vitamins, infection preventing, and other treatments. Based on the treatments given in the control group, the patients in the observation group were given the comprehensive intervention. After treatment, the serum related indicators, NBNA, and DQ in the two groups were observed.Results:The levels of serum AST, LDH, CK, and CK-MB in the observation group were significantly lower than those in the control group (P0.05). NBNA score in the observation group was significantly superior to that in the control group (P<0.05). DQ values at 3, 6, 12, 18, and 24 months in the observation group were significantly higher than those in the control group (P<0.05).Conclusions:Early comprehensive intervention on HIE patients can effectively reduce the serum cardiac enzyme levels, increase the therapeutic effect, improve the intelligence and motor development levels and DQ in order to enhance the living qualities.

    Full Text Available Abstract Background Evidence suggests that continuing medical education improves the clinical competence of general practitioners and the quality of health care services. Thus, we evaluated the relative impact of two educational strategies, critical reading (CR and problem based learning (PBL, on the clinical competence of general practitioners in a healthcare system characterized by excessive workload and fragmentation into small primary healthcare centers. Methods Clinical competence was evaluated in general practitioners assigned to three groups based on the educational interventions used: 1 critical reading intervention; 2 problem based learning intervention; and 3 no intervention (control group, which continued clinical practice as normal. The effect on the clinical competence of general practitioners was evaluated in three dimensions: the cognitive dimension, via a self-administered questionnaire; the habitual behavioral dimension, via information from patient’s medical records; and the affective dimension, through interviews with patients. A paired Student´s t-test was used to evaluate the changes in the mean clinical competence scores before and after the intervention, and a 3 x 2 ANOVA was used to analyze groups, times and their interaction. Results Nine general practitioners participated in the critical reading workshop, nine in the problem-based learning workshop, and ten were assigned to the control group. The participants exhibited no significant differences in clinical competence measures at baseline, or in socio-demographic or job characteristics (p > 0.05. Significant improvements in all three dimensions (cognitive, 45.67 vs 54.89; habitual behavioral, 53.78 vs 82.33; affective, 4.16 vs 4.76 were only observed in the problem-based learning group after the intervention (p > 0.017. Conclusions While no differences in post-intervention scores were observed between groups, we conclude that problem-based learning can be

    Full Text Available Objective: The aim of the current study was to assess the impact of computer games and computer-assisted type instruction on dictation scores of elementary school children with attention deficit – hyperactivity disorder (ADHD. Method: In this single-blind clinical trial, 37 elementary school children with ADHD, selected by convenience sampling and divided into group I (n=17 and group II (n=20, underwent eight one-hour sessions (3 sessions per week of intervention by computer games versus computer-assisted type instruction, respectively. 12 school dictation scores were considered: 4 scores preintervention, 4 scores during interventions, and 4 scores post-intervention. Dictation test was taken during each session. Data was analyzed using repeated measure ANOVA. Results: Two groups were matched for age, gender, school grade, medication, IQ, parent’s and teacher’s Conners’ scale scores, having computer at home, history of working with computer, and mean dictation scores. There was no significant difference in dictation scores before and after interventions and also between the study groups. The improvement in school dictation scores had no significant correlation with age, gender, Ritalin use, owning a computer at home and past history of computer work, baseline dictation scores, Ritalin dose, educational status, IQ, and the total score of parent’s and teacher’s Conners’ rating scale. Conclusion: Absence of significant improvement in dictation scores in study groups may be due to the confounding effect of other variables with known impact on dictation scores. Further studies in this field should also assess the change of attention and memory.

    Full Text Available Objectives: The aim of this study was to evaluate the clinical outcomes, one year after primary percutaneous coronary intervention(PCI. Patients and Methods: From September 2009 to March 2012, primary PCI was performed on 70 cases, and the data relating to their catheterization were recorded. Peri-interventional treatment data included PCI with drug-eluting or bare-metal stent or balloon angioplasty alone. Results: The mean age of the patients was 61.34+11.31 years, and 72.9% of them were males. The ratios of patients with diabetes, hypertension and, hyperlipidemia were 61.4%, 71.4%, and 52.9% respectively. In clinical follow-up, total incidence of death was 4.3%, with no death occurring during 30 days. However, 3 patients died after one-year, of which one patient (1.4% had cardiac problem and the other 2 (2.9% died because of non-cardiac reasons. Target vessel revascularization, reinfarction within 30 days, and mechanical complication or stroke were not found in any of the patients. Patients with hypertension (6% and those with LAD ST-elevation myocardial infarction (5% died after one year (P= 0.263 and P= 0.319 respectively. However, no mortality was reported in patients with RCA and LCX ST-elevation myocardial infarction. Of subjects with multivessel disease, 7% died after one-year (P= 0.161, but there was no reported mortality in those with single vessel disease.

  5. Improving clinical practice using clinical decision support systems: a systematic review of trials to identify features critical to success (United States)

    Kawamoto, Kensaku; Houlihan, Caitlin A; Balas, E Andrew; Lobach, David F


    Objective To identify features of clinical decision support systems critical for improving clinical practice. Design Systematic review of randomised controlled trials. Data sources Literature searches via Medline, CINAHL, and the Cochrane Controlled Trials Register up to 2003; and searches of reference lists of included studies and relevant reviews. Study selection Studies had to evaluate the ability of decision support systems to improve clinical practice. Data extraction Studies were assessed for statistically and clinically significant improvement in clinical practice and for the presence of 15 decision support system features whose importance had been repeatedly suggested in the literature. Results Seventy studies were included. Decision support systems significantly improved clinical practice in 68% of trials. Univariate analyses revealed that, for five of the system features, interventions possessing the feature were significantly more likely to improve clinical practice than interventions lacking the feature. Multiple logistic regression analysis identified four features as independent predictors of improved clinical practice: automatic provision of decision support as part of clinician workflow (P < 0.00001), provision of recommendations rather than just assessments (P = 0.0187), provision of decision support at the time and location of decision making (P = 0.0263), and computer based decision support (P = 0.0294). Of 32 systems possessing all four features, 30 (94%) significantly improved clinical practice. Furthermore, direct experimental justification was found for providing periodic performance feedback, sharing recommendations with patients, and requesting documentation of reasons for not following recommendations. Conclusions Several features were closely correlated with decision support systems' ability to improve patient care significantly. Clinicians and other stakeholders should implement clinical decision support systems that incorporate these

    Rai, Lav; Keast, Thomas M.; Wibowo, Henky; Yu, Kun-Chang; Draper, Jeffrey W.; Gibbs, Jason D.


    Reliable transbronchial access of peripheral lung lesions is desirable for the diagnosis and potential treatment of lung cancer. This procedure can be difficult, however, because accessory devices (e.g., needle or forceps) cannot be reliably localized while deployed. We present a fluoroscopic image-guided intervention (IGI) system for tracking such bronchoscopic accessories. Fluoroscopy, an imaging technology currently utilized by many bronchoscopists, has a fundamental shortcoming - many lung lesions are invisible in its images. Our IGI system aligns a digitally reconstructed radiograph (DRR) defined from a pre-operative computed tomography (CT) scan with live fluoroscopic images. Radiopaque accessory devices are readily apparent in fluoroscopic video, while lesions lacking a fluoroscopic signature but identifiable in the CT scan are superimposed in the scene. The IGI system processing steps consist of: (1) calibrating the fluoroscopic imaging system; (2) registering the CT anatomy with its depiction in the fluoroscopic scene; (3) optical tracking to continually update the DRR and target positions as the fluoroscope is moved about the patient. The end result is a continuous correlation of the DRR and projected targets with the anatomy depicted in the live fluoroscopic video feed. Because both targets and bronchoscopic devices are readily apparent in arbitrary fluoroscopic orientations, multiplane guidance is straightforward. The system tracks in real-time with no computational lag. We have measured a mean projected tracking accuracy of 1.0 mm in a phantom and present results from an in vivo animal study.

  7. Wearable sensors and systems. From enabling technology to clinical applications. (United States)

    Bonato, Paolo


    It is now more than 50 years since the time when clinical monitoring of individuals in the home and community settings was first envisioned. Until recently, technologies to enable such vision were lacking. However, wearable sensors and systems developed over the past decade have provided the tools to finally implement and deploy technology with the capabilities required by researchers in the field of patients' home monitoring. As discussed, potential applications of these technologies include the early diagnosis of diseases such as congestive heart failure, the prevention of chronic conditions such as diabetes, improved clinical management of neurodegenerative conditions such as Parkinson's disease, and the ability to promptly respond to emergency situations such as seizures in patients with epilepsy and cardiac arrest in subjects undergoing cardiovascular monitoring. Current research efforts are now focused on the development of more complex systems for home monitoring of individuals with a variety of preclinical and clinical conditions. Recent research on the clinical assessment of wearable technology promises to deliver methodologies that are expected to lead to clinical adoption within the next five to ten years. In particular, combining home robots and wearable technology is likely to be a key step toward achieving the goal of effectively monitoring patients in the home. These efforts to merge home robots and wearable technology are expected to enable a new generation of complex systems with the ability to monitor subjects' status, facilitate the administration of interventions, and provide an invaluable tool to respond to emergency situations.

    Purpose Healthcare workers have a main role in detection, assessment and spontaneous reporting of adverse drug reactions (ADRs), and improvement of their related knowledge, attitude and perception is essential. The goal of this study was evaluation of clinical pharmacists' interventions in improvement of knowledge, attitude and perception of healthcare workers about ADRs in a teaching referral hospital, Tehran, Iran. Method Changes in knowledge, attitude and perception of healthcare workers of Imam teaching hospital about ADRs were evaluated before and after clinical pharmacists' interventions including workshops, meetings and presentations. Results From the 100 participated subjects, 82 of them completed the study. 51% of the health workers have been aware of the Iranian Pharmacovigilance Center at the ministry of health before intervention and after that all the participants knew this centre. About awareness and detection of ADRs in patients, 69 (84.1%) healthcare workers recognised at least one, and following interventions, it was improved to 73 (89%). Only seven (8.5%) subjects have reported ADRs in before intervention phase that were increased significantly to 18 (22%) after intervention. Conclusion Clinical pharmacists' interventions were successful in improvement of healthcare workers' knowledge, attitude and perception about ADRs and spontaneous reporting in our hospital.

  9. Telehealth: Acceptability, clinical interventions and quality of life in peritoneal dialysis (United States)

    Dey, Vishal; Jones, Audrey; Spalding, Elaine M


    Introduction: Telehealth technologies are being widely adopted across the globe for management of long-term conditions. There are limited data on its use, effectiveness and patient experience in end-stage renal disease. The aim of this pilot project was to explore patient acceptability of technology and evaluate its effect on clinical interventions and quality of life in patients undergoing peritoneal dialysis. Methods: Peritoneal dialysis patients were provided with computer tablets (PODs). PODs contained a knowledge database with treatment- and symptom-based questionnaires that generated alerts for the clinical team. Alerts were reviewed daily and followed up by a telephone call or clinic visit. Interventions were at the discretion of clinicians. Data were recorded prospectively and quality of life and Quebec User Evaluation of Satisfaction with assistive Technology questionnaires evaluated at the start and end of the programme. Results: In all, 22 patients have participated over 15 months. The mean age was 61.6 years and PODs were utilised for an average of 341.9 days with 59.1% choosing to continue beyond the study period. We received a total of 1195 alerts with an average of 2.6 alerts per day. A total of 36 admissions were avoided and patients supported to self-manage on 154 occasions. Quebec User Evaluation of Satisfaction with assistive Technology scores remained high throughout the programme although no improvement in quality of life was seen. Discussion: Telehealth is useful to monitor patients with renal failure on peritoneal dialysis. It is acceptable across age groups and provides an additional resource for patients to self-manage. Satisfaction scores and retention rates suggest a high level of acceptability.

  11. Building sustainable multi-functional prospective electronic clinical data systems. (United States)

    Randhawa, Gurvaneet S; Slutsky, Jean R


    A better alignment in the goals of the biomedical research enterprise and the health care delivery system can help fill the large gaps in our knowledge of the impact of clinical interventions on patient outcomes in the real world. There are several initiatives underway to align the research priorities of patients, providers, researchers, and policy makers. These include Agency for Healthcare Research and Quality (AHRQ)-supported projects to build flexible prospective clinical electronic data infrastructure that meet the needs of these diverse users. AHRQ has previously supported the creation of 2 distributed research networks as a new approach to conduct comparative effectiveness research (CER) while protecting a patient's confidential information and the proprietary needs of a clinical organization. It has applied its experience in building these networks in directing the American Recovery and Reinvestment Act funds for CER to support new clinical electronic infrastructure projects that can be used for several purposes including CER, quality improvement, clinical decision support, and disease surveillance. In addition, AHRQ has funded a new Electronic Data Methods forum to advance the methods in clinical informatics, research analytics, and governance by actively engaging investigators from the American Recovery and Reinvestment Act-funded projects and external stakeholders.

  12. Evaluation of an Intervention among Adolescents to Reduce Preventive Misconception in HIV Vaccine Clinical Trials (United States)

    Lally, Michelle; Goldsworthy, Richard; Sarr, Moussa; Kahn, Jessica; Brown, Larry; Peralta, Ligia; Zimet, Greg


    Purpose Placebo and randomization are important concepts that must be understood before youth can safely participate in HIV vaccine studies or other biomedical trials for HIV prevention. These concepts are central to the phenomenon of preventive misconception which may be associated with an increase in risk behavior among study participants related to mistaken beliefs. Persuasive messaging, traditionally used in the field of marketing, could enhance educational efforts associated with randomized clinical trials. Methods Two educational brochures were designed to increase knowledge about HIV vaccine clinical trials via 1 and 2-sided persuasive messaging. Through the Adolescent Medicine Trials Network, 120 youth were enrolled, administered a mock HIV vaccine trial consent, and then randomized to receive either no supplemental information or one of the two brochures. Results The 2-sided brochure group in which common clinical trial misconceptions were acknowledgedand then refuted had significantly higher scores on knowledge of randomization and interpretation of side effects than the consent-only control group, and willingness to participate in an HIV vaccine trial was not decreased with the use of this brochure. Conclusion Two sided persuasive messaging improves understanding of the concepts of randomization and placebo among youth who would consider participating in an HIV vaccine trial. Further evaluation of this approach should be considered for at-risk youth participating in an actual trial of a biomedical intervention for HIV prevention. PMID:24613097

    Full Text Available Nurse involvement in research is essential to the expansion of nursing science and improved care for patients. The research participation challenges encountered by nurses providing direct care (direct care nurses include balancing patient care demands with research, adjusting to fluctuating staff and patient volumes, working with interdisciplinary personnel, and feeling comfortable with their knowledge of the research process. The purpose of this paper is to describe efforts to engage nurses in research for the Stories and Music for Adolescent/Young Adult Resilience during Transplant (SMART study. SMART was an NIH-funded, multisite, randomized, behavioral clinical trial of a music therapy intervention for adolescents/young adults (AYA undergoing stem cell transplant for an oncology condition. The study was conducted at 8 sites by a large multidisciplinary team that included direct care nurses, advanced practice nurses, and nurse researchers, as well as board-certified music therapists, clinical research coordinators, and physicians. Efforts to include direct care nurses in the conduct of this study fostered mutual respect across disciplines in both academic and clinical settings.

  14. Distance magnetic nanoparticle detection using a magnetoelectric sensor for clinical interventions (United States)

    Huong Giang, D. T.; Dang, D. X.; Toan, N. X.; Tuan, N. V.; Phung, A. T.; Duc, N. H.


    Distance magnetic nanoparticle detections were investigated by using a magnetoelectric based magnetic sensor with a long type bilayer Metglas/PZT laminate composite. In homogeneous magnetic fields, the sensor exhibits a sensitivity of 307.4 mV/Oe, which is possible for a detection limit of 2.7 × 10-7 emu. This sensor can detect an amount of 0.31 μg of the superparamagnetic Fe3O4-chitosan fluid at 2 mm height above the sensor surface. To detect a spot with magnetic nanoparticles at a distance of about 7.6 mm, it should contain at least 50 μg of iron oxide. This approach can develop the local detection of magnetic nanoparticles at a depth of centimeters in the body during clinical interventions.

    Nilson Abrão Szylit

    Full Text Available CONTEXT: Interstitial pregnancy is a rare form of ectopic pregnancy for which the best therapeutic course of action has yet to be determined. Surgical intervention entails a high risk of hemorrhage due to the great vascularization of the cornual region of the uterus. Case descriptions facilitate the analysis of results and aid clinicians in determining the most appropriate course of action in these situations. CASE REPORT: In a patient with an ultrasound diagnosis of interstitial pregnancy, clinical treatment using methotrexate was chosen. However, after one week, there was a marked decline in the serum level of the β subunit of chorionic gonadotropin hormone, although an ultrasound examination revealed embryonic cardiac activity. A second dose of the chemotherapy was administered. Embryonic cardiac activity persisted 48 hours later. Video laparoscopy was performed to achieve right-side cornual resection, which resulted in satisfactory resolution of the case.

    Godfrey Katende


    Full Text Available Noncommunicable diseases (NCDs pose a significant global burden in both developed and developing countries. It is estimated that, by 2025, 41.7% of males and 38.7% of females in Sub-Saharan Africa will develop high blood pressure (HBP. This is particularly true in Uganda with hypertensive prevalence rates estimated to range from 22.5% to 30.5%. Coupled with low levels of detection, treatment, and control, hypertension represents a Ugandan public health crisis. An innovative WHO-ISH education program culturally was adapted in a pilot study and focused on knowledge, skills, and attitudes (KSA of nurses caring for hypertensive patients in an outpatient clinic. Pre-post intervention data was collected and analyzed in which significant improvements were noted on all the three outcome measures. This pilot study demonstrated that nurses’ knowledge, skills, and attitudes could be significantly improved with a multimodal education program implemented in a low resource environment.

  18. [Ageism and its clinical consequences in oncogeriatry: a review of existing data and intervention leads]. (United States)

    Schroyen, S; Adam, S; Jerusalem, G; Missotten, P


    Aging is a risk factor in oncology. Indeed, it is estimated that, in 2030, 70% of diagnosed cancers in the United States will concern subjects older than 65 years. Paradoxically, elderly are often excluded from clinical trials and are undertreated compared to younger patients. An important explanatory factor (and yet still not considered!) for these observations is the age stigma (in other words our stereotypes linked to age, and so ageism), age being actually the main motive for discrimination. In this perspective, our aim is to present ageism manifestations in oncogeriatry and their direct consequences for patients, interlocutors (that is to say health professionals) and interactions between them. Throughout this article, we will enhance our remarks by data from researches in "normal" aging. Before ending, we will give some intervention leads potentially applicable in oncogeriatry, to reduce ageism deleterious effect.

  19. The Efficacy of Oral Nutritional Intervention in Malnourished Cancer Patients: a Systemic Review (United States)


    Cancer is currently a leading cause of deaths worldwide and the number of new cases is growing rapidly in both, developed and developing countries. Nutritional management during and after cancer treatment affects treatment efficacy and patient quality of life (QOL). This review systemically examined the effect of oral nutritional interventions on nutritional and clinical outcomes in cancer patients. We especially focused on outcomes such as nutritional status indices, immune-associated biochemical markers, and QOL assessments to provide insights on the applicability of different outcomes. A total of 28 papers were selected for systematic review. The nutritional composition of oral nutritional supplements (ONS), outcome measures, and efficacy of the oral nutritional interventions were summarized and discussed. Most ONS contain 1 or more functional components in addition to basic nutrients. Each study used various outcome measures and significant efficacy was observed for a limited number of measures. Nutritional status indices, QOL measures, and the duration of hospital stay improved in about 40% of the studies. One or more markers of immune function and inflammatory responses were improved by ONS in 65% of the selected studies. These results suggest that appropriate use of ONS may be an ideal way to improve treatment efficacy; however, additional intervention trials are required to confirm these findings. PMID:27812512

  1. Nursing Education Interventions for Managing Acute Pain in Hospital Settings: A Systematic Review of Clinical Outcomes and Teaching Methods. (United States)

    Drake, Gareth; de C Williams, Amanda C


    The objective of this review was to examine the effects of nursing education interventions on clinical outcomes for acute pain management in hospital settings, relating interventions to health care behavior change theory. Three databases were searched for nursing education interventions from 2002 to 2015 in acute hospital settings with clinical outcomes reported. Methodological quality was rated as strong, moderate, or weak using the Effective Public Health Practice Project Quality Assessment Tool for quantitative studies. The 12 eligible studies used varied didactic and interactive teaching methods. Several studies had weaknesses attributable to selection biases, uncontrolled confounders, and lack of blinding of outcome assessors. No studies made reference to behavior change theory in their design. Eight of the 12 studies investigated nursing documentation of pain assessment as the main outcome, with the majority reporting positive effects of education interventions on nursing pain assessment. Of the remaining studies, two reported mixed findings on patient self-report of pain scores as the key measure, one reported improvements in patient satisfaction with pain management after a nursing intervention, and one study found an increase in nurses' delivery of a relaxation treatment following an intervention. Improvements in design and evaluation of nursing education interventions are suggested, drawing on behavior change theory and emphasizing the relational, contextual, and emotionally demanding nature of nursing pain management in hospital settings.

    Substance use among people living with HIV is high, and screening, brief intervention, and referral to treatment (SBIRT) is an evidence-based approach to addressing the issue. We examined whether patients would participate in a technology-based SBIRT program in an urban HIV clinic. An SBIRT intervention was programmed into the clinic's web-based patient portal linked to their personal health record. We examined: demographic, health, HIV, and substance use characteristics of participants who completed the web-based intervention compared to those who did not. Fewer than half of the 96 participants assigned to the web-based SBIRT completed it (n = 39; 41 %). Participants who completed the web-based intervention had significantly higher amphetamine SSIS scores than those who did not complete the intervention. Participants whose substance use is more harmful may be more motivated to seek help from a variety of sources. In addition, it is important that technology-based approaches to behavioral interventions in clinics take into consideration feasibility, client knowledge, and comfort using technology.

If desired choices are freely accessible, and the act of choosing is efficient and unconstrained, then the outcome is optimized quality of life. The c-c model fits many clinical situations where improved quality of life is a goal, and interventions may be aimed at relieving health-related restrictions of the patient’s desired activities. Aims: To determine the impact of health restrictions of choices and choosing on indicators and outcomes reflecting quality of life. Method: Secondary analysis of a community-based health survey of three ethnic groups, 65 years and older (n = 2,130, repeated after 18 months, with mortality over 6 years. Findings: Complaints of health restrictions of desired activities accounted for about half the variance of all determinants of a quality of life proxy indicator, and had a high frequency. Such complaints also predicted declines in mood and function, higher death rates, and increased service use.Conclusions: Clinical trials are warranted of the efficacy for quality of life improvement of interventions that focus on the relief of health-induced restrictions of desired activities.Keywords: choice, quality of life, aging, health restrictions

    Kilian, H


    Proceeding from contradicting practical requirements some reflections are being made on the possibility of using psycho-diagnostic requests for systemic short interventions in "problem determined systems". Referred to a standard diagnostic situation some possible circular and hypothetic questions of a first interview and potential new interpretations within a concluding statement are listed and being illustrated with 2 case studies. There are finally some considerations on possible functions of requests for psychological testing in "problem-determined systems".

    * Conventional automated interpretative reporting systems use standard or "canned" comments for patient reports. These are result-specific and do not generally refer to the patient context. * Laboratory information systems (LIS) are limited in their application of patient-specific content of reporting. * Patient-specific interpretation requires extensive cross-referencing to other information contained in the LIS such as previous test results, other related tests, and clinical notes, both current and previous. * Expert systems have the potential to improve reporting quality by enabling patient-specific reporting in clinical laboratories.

    Full Text Available At the Research Clinic for Holistic Medicine in Copenhagen, 43 patients who presented with low or very low self-esteem were treated with psychodynamic short-term therapy complemented with bodywork. They received an average of 20 sessions at a cost of 1,600 EURO. The bodywork helped the patients to confront old emotional pain from childhood trauma repressed to the body-mind. Results showed that 60.5% recovered from low selfesteem (95% CI: 44.41–75.02%. Calculated from this, we have NNT = 1.33–2.25. Almost all aspects of life improved at the same time (p < 0.01: physical health, mental health, quality of life, and ability to function in a number of important areas (partner, friends, sexually, and socially.

    Full Text Available In this research a fully sensorized cooperative robot system for manipulation of needles is presented. The setup consists of a DLR/KUKA Light Weight Robot III especially designed for safe human/robot interaction, a FD-CT robot-driven angiographic C-arm system, and a navigation camera. Also, new control strategies for robot manipulation in the clinical environment are introduced. A method for fast calibration of the involved components and the preliminary accuracy tests of the whole possible errors chain are presented. Calibration of the robot with the navigation system has a residual error of 0.81 mm (rms with a standard deviation of ±0.41 mm. The accuracy of the robotic system while targeting fixed points at different positions within the workspace is of 1.2 mm (rms with a standard deviation of ±0.4 mm. After calibration, and due to close loop control, the absolute positioning accuracy was reduced to the navigation camera accuracy which is of 0.35 mm (rms. The implemented control allows the robot to compensate for small patient movements.

  12. Beyond the SYNTAX score--advantages and limitations of other risk assessment systems in left main percutaneous coronary intervention. (United States)

    Capodanno, Davide


    Risk stratification is an emerging topic in the modern management of patients with left main disease referred for percutaneous coronary intervention (PCI). Recent years have witnessed an explosive multiplication of risk models for prognostic stratification in complex PCI. Many of this models deal with modification of the angiographic SYNTAX score, or seek to overcome its known pitfalls and limitations, including lack of clinical and functional information, inter- and intra-observer variabilities, and poor calibration. Risk scoring systems beyond the SYNTAX score may be classified into angiographic (residual SYNTAX score, coronary artery bypass grafting SYNTAX score), clinical (EuroSCORE I and II, ACEF score and modified ACEF scores), combined clinical and angiographic (Global Risk Classification, Clinical SYNTAX score, logistic Clinical SYNTAX score, SYNTAX score II) and functional (Functional SYNTAX score). This article reviews current concepts in risk modeling and explores the advantages and limitations of the alternatives to the SYNTAX score in patients undergoing left main PCI. 

  13. Mentalizing Makes Parenting Work: A Review about Parental Reflective Functioning and Clinical Interventions to Improve It. (United States)

    Camoirano, Andrea


    In the last decade several studies have investigated the role of parental reflective functioning (RF), defined as the parental ability to understand his/her child's mental states, on the child's development. Herein, a narrative review on parental RF is presented aimed at (1) presenting an overview of the existing empirical studies, (2) pinpointing unrequited questions, and (3) identifying future research directions. Specifically, the current review focused on (a) the impact of parental RF on the quality of caregiving and the child's attachment security, (b) the effect of parental RF on the child's emotion regulation and the child's RF, (c) maternal RF in women with a history of neglect and abuse, (d) the efficacy of mentalization-based clinical interventions, and (e) the recently developed Parental Reflective Questionnaire. The following terms "maternal RF," "paternal RF," "parental RF," "parental mentalization," "maternal mentalization," and "paternal mentalization" were searched in titles, abstracts, and main texts using Medline, Web of Science, and Scopus databases. Next, a search in Mendeley was also conducted. Inclusion criteria comprised original articles if they refer to the RF Scale (Fonagy et al., 1998) and were published in an English language, peer-reviewed journal before July, 2016. According to exclusion criteria, dissertations, qualitative or theoretical papers, and chapters in books were not taken into account. The review includes 47 studies that, taken together, supported the notion that higher parental RF was associated with adequate caregiving and the child's attachment security, whereas low maternal RF was found in mothers whose children suffered from anxiety disorders, impairment in emotion regulation, and externalizing behaviors. In addition, higher parental RF was associated with better mentalizing abilities in children. However, unexpected findings have emerged from the most recent randomized controlled trials that tested the efficacy of

    Forbes, Lindsay J. L.; Forster, Alice S.; Dodd, Rachael H.; Tucker, Lorraine; Laming, Rachel; Sellars, Sarah; Patnick, Julietta; Ramirez, Amanda J.


    Background. Women over 70 with breast cancer have poorer one-year survival and present at a more advanced stage than younger women. Promoting early symptomatic presentation in older women may reduce stage cost effectively and is unlikely to lead to overdiagnosis. After examining efficacy in a randomised controlled trial, we piloted a brief health professional-delivered intervention to equip women to present promptly with breast symptoms, as an integral part of the final invited mammogram at age ~70, in the English National Health Service Breast Screening Programme. Methods. We trained mammographers, who then offered the intervention to older women in four breast screening services. We examined breast cancer awareness at baseline and one month in women receiving the intervention, and also in a service where the intervention was not offered. Results. We trained 27 mammographers to deliver the intervention confidently to a high standard. Breast cancer awareness increased 7-fold at one month in women receiving the intervention compared with 2-fold in the comparison service (odds ratio 15.2, 95% confidence interval 10.0 to 23.2). Conclusions. The PEP Intervention can be implemented in routine clinical practice with a potency similar to that achieved in a randomised controlled trial. It has the potential to reduce delay in diagnosis for breast cancer in older women. PMID:23213334

  17. Radiation dose reduction and new image modalities development for interventional C-arm imaging system (United States)

    Niu, Kai

    Cardiovascular disease and stroke are the leading health problems and causes of death in the US. Due to the minimally invasive nature of the evolution of image guided techniques, interventional radiological procedures are becoming more common and are preferred in treating many cardiovascular diseases and strokes. In addition, with the recent advances in hardware and device technology, the speed and efficacy of interventional treatment has significantly improved. This implies that more image modalities can be developed based on the current C-arm system and patients treated in interventional suites can potentially experience better health outcomes. However, during the treatment patients are irradiated with substantial amounts of ionizing radiation with a high dose rate (digital subtraction angiography (DSA) with 3muGy/frame and 3D cone beam CT image with 0.36muGy/frame for a Siemens Artis Zee biplane system) and/or a long irradiation time (a roadmapping image sequence can be as long as one hour during aneurysm embolization). As a result, the patient entrance dose is extremely high. Despite the fact that the radiation dose is already substantial, image quality is not always satisfactory. By default a temporal average is used in roadmapping images to overcome poor image quality, but this technique can result in motion blurred images. Therefore, reducing radiation dose while maintaining or even improving the image quality is an important area for continued research. This thesis is focused on improving the clinical applications of C-arm cone beam CT systems in two ways: (1) Improve the performance of current image modalities on the C-arm system. (2) Develop new image modalities based on the current system. To be more specific, the objectives are to reduce radiation dose for current modalities (e.g., DSA, fluoroscopy, roadmapping, and cone beam CT) and enable cone beam CT perfusion and time resolved cone beam CT angiography that can be used to diagnose and triage acute

    Excess mortality in persons with severe mental disorders (SMD) is a major public health challenge that warrants action. The number and scope of truly tested interventions in this area remain limited, and strategies for implementation and scaling up of programmes with a strong evidence base are scarce. Furthermore, the majority of available interventions focus on a single or an otherwise limited number of risk factors. Here we present a multilevel model highlighting risk factors for excess mortality in persons with SMD at the individual, health system and socio‐environmental levels. Informed by that model, we describe a comprehensive framework that may be useful for designing, implementing and evaluating interventions and programmes to reduce excess mortality in persons with SMD. This framework includes individual‐focused, health system‐focused, and community level and policy‐focused interventions. Incorporating lessons learned from the multilevel model of risk and the comprehensive intervention framework, we identify priorities for clinical practice, policy and research agendas. PMID:28127922

  19. Cancer and Anorexia Nervosa in the Adolescence: A Family-Based Systemic Intervention

    Directory of Open Access Journals (Sweden)

    Gabriella De Benedetta


    Full Text Available Objective. Anorexia nervosa is difficult to diagnose in cancer patients since weight loss, aversion for food, and eating disturbances are frequent in patients undergoing chemotherapy and radiotherapy. Nevertheless, efforts are mandatory to recognize and manage this condition which may occur also in cancer patients with a special regard to adolescents. Methods. Through the clinical history of Anna, a 15-year-old adolescent with advanced cancer, we describe the effectiveness of a family-based systemic intervention to manage anorexia nervosa occurring in concomitance to osteosarcoma. Results. Through a two-year psychotherapy period involving different techniques applied to the whole family such as family genogram, family collage, and sculpture of family time, Anna was relieved from her condition. Conclusions. Upon early diagnosis and appropriate treatment, anorexia nervosa can be effectively approached in adolescent cancer patients. The presence of a life-threatening medical condition such as cancer may provide motivation for a patient to control disordered eating behavior in the context of an appropriate family-based systemic intervention. The general frame of anorexia occurring in cancer-bearing adolescents is reviewed and discussed.

  20. PRIME – PRocess modelling in ImpleMEntation research: selecting a theoretical basis for interventions to change clinical practice

    Directory of Open Access Journals (Sweden)

    Pitts Nigel


    Full Text Available Abstract Background Biomedical research constantly produces new findings but these are not routinely translated into health care practice. One way to address this problem is to develop effective interventions to translate research findings into practice. Currently a range of empirical interventions are available and systematic reviews of these have demonstrated that there is no single best intervention. This evidence base is difficult to use in routine settings because it cannot identify which intervention is most likely to be effective (or cost effective in a particular situation. We need to establish a scientific rationale for interventions. As clinical practice is a form of human behaviour, theories of human behaviour that have proved useful in other similar settings may provide a basis for developing a scientific rationale for the choice of interventions to translate research findings into clinical practice. The objectives of the study are: to amplify and populate scientifically validated theories of behaviour with evidence from the experience of health professionals; to use this as a basis for developing predictive questionnaires using replicable methods; to identify which elements of the questionnaire (i.e., which theoretical constructs predict clinical practice and distinguish between evidence compliant and non-compliant practice; and on the basis of these results, to identify variables (based on theoretical constructs that might be prime targets for behaviour change interventions. Methods We will develop postal questionnaires measuring two motivational, three action and one stage theory to explore five behaviours with 800 general medical and 600 general dental practitioners. We will collect data on performance for each of the behaviours. The relationships between predictor variables (theoretical constructs and outcome measures (data on performance in each survey will be assessed using multiple regression analysis and structural equation

    Laura Fernández-García


    Full Text Available Toxin-antitoxin (TA systems are prevalent in bacteria and archaea. Although not essential for normal cell growth, TA systems are implicated in multiple cellular functions associated with survival under stress conditions. Clinical strains of bacteria are currently causing major human health problems as a result of their multidrug resistance, persistence and strong pathogenicity. Here, we present a review of the TA systems described to date and their biological role in human pathogens belonging to the ESKAPE group (Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa and Enterobacter spp. and others of clinical relevance (Escherichia coli, Burkholderia spp., Streptococcus spp. and Mycobacterium tuberculosis. Better understanding of the mechanisms of action of TA systems will enable the development of new lines of treatment for infections caused by the above-mentioned pathogens.

  2. The First Intervention Study in Elder Self-Neglect: A Randomized Clinical Trial to Improve Vitamin D Levels (United States)

    Burnett, Jason; Hochschild, Ann; Smith, Scott M.; Diamond, Pam; Stotts, Angela; Dyer, Carmel


    Despite high mortality rates, elder self-neglect is characterized by refusal of medical and social interventions. To date there have been no tested clinical interventions in elders who self-neglect. Previous research from the TEAM Institute has shown significantly low vitamin D levels in this population. This study aimed to determine the feasibility of a clinical intervention. Replacement of vitamin D was chosen because of its ease of administration and favorable safety profile. Methods: A randomized clinical trial using directly observed therapy of vitamin D was conducted using 50 elders, >65 years of age, with Adult Protective Services (APS) validated self-neglect. A staggered intervention with waiting controls was used to maximize statistical power. One-third (n=17) of the group was administered 50,000 IU vitamin D2 (ergocalciferol) monthly and the remainder (n=33) were administered 400 IU monthly. Serum 25-OH vitamin D was assessed at baseline and 5-months. Results: 69% agreed to participate in the study and of those n=40 (80%) remained at 5-months. At baseline, 12% (n=7) were deficient in vitamin D (vitamin D levels (vitamin D level was 59 nmol/L +25 (mean SD), and increased significantly to 72nmol/L +21 nmol/L at 5-months. Conclusion: These data are the first to provide evidence that clinical interventions are feasible in elders who self-neglect. The increase in vitamin D levels confirmed that the study personnel were able to successfully intervene community-dwelling elders with self-neglect. This study sets the precedent for future intervention and prevention studies

    Full Text Available Abstract Background Objective of the study was to assess the effects of strategies to integrate targeted priority population, health and nutrition interventions into health systems on patient health outcomes and health system effectiveness and thus to compare integrated and non-integrated health programmes. Methods Systematic review using Cochrane methodology of analysing randomised trials, controlled before-and-after and interrupted time series studies. We defined specific strategies to search PubMed, CENTRAL and the Cochrane Effective Practice and Organisation of Care Group register, considered studies published from January 1998 until September 2008, and tracked references and citations. Two reviewers independently agreed on eligibility, with an additional arbiter as needed, and extracted information on outcomes: primary (improved health, financial protection, and user satisfaction and secondary (improved population coverage, access to health services, efficiency, and quality using standardised, pre-piloted forms. Two reviewers in the final stage of selection jointly assessed quality of all selected studies using the GRADE criteria. Results Of 8,274 citations identified 12 studies met inclusion criteria. Four studies compared the benefits of Integrated Management of Childhood Illnesses in Tanzania and Bangladesh, showing improved care management and higher utilisation of health facilities at no additional cost. Eight studies focused on integrated delivery of mental health and substance abuse services in the United Kingdom and United States of America. Integrated service delivery resulted in better clinical outcomes and greater reduction of substance abuse in specific sub-groups of patients, with no significant difference found overall. Quality of care, patient satisfaction, and treatment engagement were higher in integrated delivery models. Conclusions Targeted priority population health interventions we identified led to improved health

    The aim of this article is to discuss how the systems science approach can be used to optimize intervention strategies in food animal systems. It advocates the idea that the challenges of maintaining a safe food supply are best addressed by integrating modeling and mathematics with biological studies critical to formulation of public policy to address these challenges. Much information on the biology and epidemiology of food animal systems has been characterized through single-discipline methods, but until now this information has not been thoroughly utilized in a fully integrated manner. The examples are drawn from our current research. The first, explained in depth, uses clinical mastitis to introduce the concept of dynamic programming to optimize management decisions in dairy cows (also introducing the curse of dimensionality problem). In the second example, a compartmental epidemic model for Johne's disease with different intervention strategies is optimized. The goal of the optimization strategy depends on whether there is a relationship between Johne's and Crohn's disease. If so, optimization is based on eradication of infection; if not, it is based on the cow's performance only (i.e., economic optimization, similar to the mastitis example). The third example focuses on food safety to introduce risk assessment using Listeria monocytogenes and Salmonella Typhimurium. The last example, practical interventions to effectively manage antibiotic resistance in beef and dairy cattle systems, introduces meta-population modeling that accounts for bacterial growth not only in the host (cow), but also in the cow's feed, drinking water and the housing environment. Each example stresses the need to progress toward multi-scale modeling. The article ends with examples of multi-scale systems, from food supply systems to Johne's disease. Reducing the consequences of foodborne illnesses (i.e., minimizing disease occurrence and associated costs) can only occur through an

  5. Shared governance in a clinic system. (United States)

    Meyers, Michelle M; Costanzo, Cindy


    Shared governance in health care empowers nurses to share in the decision-making process, which results in decentralized management and collective accountability. Share governance practices have been present in hospitals since the late 1970s. However, shared governance in ambulatory care clinics has not been well established. The subjects of this quality project included staff and administrative nurses in a clinic system. The stakeholder committee chose what model of shared governance to implement and educated clinic staff. The Index of Professional Nursing Governance measured a shared governance score pre- and postimplementation of the Clinic Nursing Council. The Clinic Nursing Council met bimonthly for 3 months during this project to discuss issues and make decisions related to nursing staff. The Index of Professional Nursing Governance scores indicated traditional governance pre- and postimplementation of the Clinic Nursing Council, which is to be expected. The stakeholder committee was beneficial to the initial implementation process and facilitated staff nurse involvement. Shared governance is an evolutionary process that develops empowered nurses and nurse leaders.

  6. Health record systems that meet clinical needs

    Directory of Open Access Journals (Sweden)

    Gabriella Negrini


    Full Text Available Introduction Increased attention has recently been focused on health record systems as a result of accreditation programs, a growing emphasis on patient safety, and the increase in lawsuits involving allegations of malpractice. Health-care professionals frequently express dissatisfaction with the health record systems and complain that the data included are neither informative nor useful for clinical decision making. This article reviews the main objectives of a hospital health record system, with emphasis on its roles in communication and exchange among clinicians, patient safety, and continuity of care, and asks whether current systems have responded to the recent changes in the Italian health-care system.Discussion If health records are to meet the expectations of all health professionals, the overall information need must be carefully analyzed, a common data set must be created, and essential specialist contributions must be defined. Working with health-care professionals, the hospital management should define how clinical information is to be displayed and organized, identify a functionally optimal layout, define the characteristics of ongoing patient assessment in terms of who will be responsible for these activities and how often they will be performed. Internet technology can facilitate data retrieval and meet the general requirements of a paper-based health record system, but it must also ensure focus on clinical information, business continuity, integrity, security, and privacy.Conclusions The current health records system needs to be thoroughly revised to increase its accessibility, streamline the work of health-care professionals who consult it, and render it more useful for clinical decision making—a challenging task that will require the active involvement of the many professional classes involved.

  7. Using systems thinking to support clinical system transformation. (United States)

    Best, Allan; Berland, Alex; Herbert, Carol; Bitz, Jennifer; van Dijk, Marlies W; Krause, Christina; Cochrane, Douglas; Noel, Kevin; Marsden, Julian; McKeown, Shari; Millar, John


    Purpose - The British Columbia Ministry of Health's Clinical Care Management initiative was used as a case study to better understand large-scale change (LSC) within BC's health system. Using a complex system framework, the purpose of this paper is to examine mechanisms that enable and constrain the implementation of clinical guidelines across various clinical settings. Design/methodology/approach - Researchers applied a general model of complex adaptive systems plus two specific conceptual frameworks (realist evaluation and system dynamics mapping) to define and study enablers and constraints. Focus group sessions and interviews with clinicians, executives, managers and board members were validated through an online survey. Findings - The functional themes for managing large-scale clinical change included: creating a context to prepare clinicians for health system transformation initiatives; promoting shared clinical leadership; strengthening knowledge management, strategic communications and opportunities for networking; and clearing pathways through the complexity of a multilevel, dynamic system. Research limitations/implications - The action research methodology was designed to guide continuing improvement of implementation. A sample of initiatives was selected; it was not intended to compare and contrast facilitators and barriers across all initiatives and regions. Similarly, evaluating the results or process of guideline implementation was outside the scope; the methods were designed to enable conversations at multiple levels - policy, management and practice - about how to improve implementation. The study is best seen as a case study of LSC, offering a possible model for replication by others and a tool to shape further dialogue. Practical implications - Recommended action-oriented strategies included engaging local champions; supporting local adaptation for implementation of clinical guidelines; strengthening local teams to guide implementation; reducing

    Full Text Available This paper investigated the cost-effectiveness of a computer-assisted Clinical Decision Support System (CDSS in the identification of maternal complications in Ghana.A cost-effectiveness analysis was performed in a before- and after-intervention study. Analysis was conducted from the provider's perspective. The intervention area was the Kassena- Nankana district where computer-assisted CDSS was used by midwives in maternal care in six selected health centres. Six selected health centers in the Builsa district served as the non-intervention group, where the normal Ghana Health Service activities were being carried out.Computer-assisted CDSS increased the detection of pregnancy complications during antenatal care (ANC in the intervention health centres (before-intervention = 9 /1,000 ANC attendance; after-intervention = 12/1,000 ANC attendance; P-value = 0.010. In the intervention health centres, there was a decrease in the number of complications during labour by 1.1%, though the difference was not statistically significant (before-intervention =107/1,000 labour clients; after-intervention = 96/1,000 labour clients; P-value = 0.305. Also, at the intervention health centres, the average cost per pregnancy complication detected during ANC (cost -effectiveness ratio decreased from US$17,017.58 (before-intervention to US$15,207.5 (after-intervention. Incremental cost -effectiveness ratio (ICER was estimated at US$1,142. Considering only additional costs (cost of computer-assisted CDSS, cost per pregnancy complication detected was US$285.Computer -assisted CDSS has the potential to identify complications during pregnancy and marginal reduction in labour complications. Implementing computer-assisted CDSS is more costly but more effective in the detection of pregnancy complications compared to routine maternal care, hence making the decision to implement CDSS very complex. Policy makers should however be guided by whether the additional benefit is worth

This study evaluated the effectiveness of an early ESDM-inspired intervention, in a small group of toddlers, delivered at low intensity by the Italian Public Health System.Methods: Twenty-one toddlers at risk for autism spectrum disorders, aged 20–36 months, received 3 hours/wk of one-to-one ESDM-inspired intervention by trained therapists, combined with parents’ and teachers’ active engagement in ecological implementation of treatment. The mean duration of treatment was 15 months. Cognitive and communication skills, as well as severity of autism symptoms, were assessed by using standardized measures at pre-intervention (Time 0 [T0]; mean age =27 months and post-intervention (Time 1 [T1]; mean age =42 months.Results: Children made statistically significant improvements in the language and cognitive domains, as demonstrated by a series of nonparametric Wilcoxon tests for paired data. Regarding severity of autism symptoms, younger age at diagnosis was positively associated with greater improvement at post-assessment.Conclusion: Our results are consistent with the literature that underlines the importance of early diagnosis and early intervention, since prompt diagnosis can reduce the severity of autism symptoms and improve cognitive and language skills in younger children

    This was a prospective study comparing two groups: personalized and non-personalized treatment with P2Y12 receptor blockers during a 12-month follow-up. We aimed to investigate whether personalized antiplatelet treatment in patients with high on-treatment platelet reactivity (HTPR) improves clinical outcome. Platelet reactivity was assessed by adenosine diphosphate induced aggregation using a multiple electrode aggregometry (MEA) in 798 patients with coronary artery disease undergoing percutaneous coronary intervention (PCI). Patients with HTPR received up to four repeated loading doses of clopidogrel or prasugrel in the personalized treatment group (n=403), whereas no change in the treatment strategy was undertaken in patients with HTPR in the non-personalized treatment group (n=395). There were fewer major adverse cardiac events (MACE) in the personalized treatment group than in the non-personalized treatment group (7.4% compared with 15.3% respectively; Ppersonalized treatment group as compared with the non-personalized treatment group [hazard ratio (HR)=0.49; 95% confidence interval (CI): 0.31-0.77; Ppersonalized antiplatelet treatment over the non-personalized treatment (ischemic and bleedings events: 8.2% versus 18.7% respectively; HR=0.46; 95%CI: 0.29-0.70; Ppersonalized antiplatelet treatment might improve patients' outcome without increasing bleeding complications compared with the non-personalized treatment during a 12-month follow-up.

  11. Chinese health care system and clinical epidemiology (United States)

    Sun, Yuelian; Gregersen, Hans; Yuan, Wei


    China has gone through a comprehensive health care insurance reform since 2003 and achieved universal health insurance coverage in 2011. The new health care insurance system provides China with a huge opportunity for the development of health care and medical research when its rich medical resources are fully unfolded. In this study, we review the Chinese health care system and its implication for medical research, especially within clinical epidemiology. First, we briefly review the population register system, the distribution of the urban and rural population in China, and the development of the Chinese health care system after 1949. In the following sections, we describe the current Chinese health care delivery system and the current health insurance system. We then focus on the construction of the Chinese health information system as well as several existing registers and research projects on health data. Finally, we discuss the opportunities and challenges of the health care system in regard to clinical epidemiology research. China now has three main insurance schemes. The Urban Employee Basic Medical Insurance (UEBMI) covers urban employees and retired employees. The Urban Residence Basic Medical Insurance (URBMI) covers urban residents, including children, students, elderly people without previous employment, and unemployed people. The New Rural Cooperative Medical Scheme (NRCMS) covers rural residents. The Chinese Government has made efforts to build up health information data, including electronic medical records. The establishment of universal health care insurance with linkage to medical records will provide potentially huge research opportunities in the future. However, constructing a complete register system at a nationwide level is challenging. In the future, China will demand increased capacity of researchers and data managers, in particular within clinical epidemiology, to explore the rich resources. PMID:28356772

  12. Nursing interventions classification in systematized nomenclature of medicine clinical terms: a cross-mapping validation. (United States)

    Park, Hyun-Tae; Lu, Der-Fa; Konicek, Debra; Delaney, Connie


    The Systemized Nomenclature of Medical Clinical Terms, or SNOMED-CT, was developed to create a comprehensive clinical healthcare reference terminology. Standardized nursing language concepts and terminologies recognized by the American Nurses Association have been added to SNOMED-CT and include the NANDA's Taxonomy II, NIC, NOC, the Omaha System, and CCC. The relationship link between terminologies and SNOMED-CT is provided in a mapping table, which identifies the source terminology. The purpose of this study is to examine the validity of the cross-mapping between the source system (NIC) and the target system (SNOMED-CT) using the methodology developed by Lu and colleagues to detect misassigned concepts. Knowledge representation concepts in the NIC and SNOMED-CT systems were compared using expert human judgment. Of 514 NIC concepts, 14 (2.7%) were identified as misassigned in SNOMED-CT. Two inappropriate representations of concepts were discovered in NIC. Results and recommendations were given to NIC and to SNOMED-CT.

  13. CLARA: an integrated clinical research administration system. (United States)

    Bian, Jiang; Xie, Mengjun; Hogan, William; Hutchins, Laura; Topaloglu, Umit; Lane, Cheryl; Holland, Jennifer; Wells, Thomas


    Administration of human subject research is complex, involving not only the institutional review board but also many other regulatory and compliance entities within a research enterprise. Its efficiency has a direct and substantial impact on the conduct and management of clinical research. In this paper, we report on the Clinical Research Administration (CLARA) platform developed at the University of Arkansas for Medical Sciences. CLARA is a comprehensive web-based system that can streamline research administrative tasks such as submissions, reviews, and approval processes for both investigators and different review committees on a single integrated platform. CLARA not only helps investigators to meet regulatory requirements but also provides tools for managing other clinical research activities including budgeting, contracting, and participant schedule planning.

  14. Review of VA/DOD Clinical Practice Guideline on management of acute stress and interventions to prevent posttraumatic stress disorder

    Directory of Open Access Journals (Sweden)

    William P. Nash, MD


    Full Text Available This article summarizes the recommendations of the Department of Veterans Affairs (VA/Department of Defense (DOD VA/DOD Clinical Practice Guideline for Management of Post-Traumatic Stress that pertain to acute stress and the prevention of posttraumatic stress disorder, including screening and early interventions for acute stress states in various settings. Recommended interventions during the first 4 days after a potentially traumatic event include attending to safety and basic needs and providing access to physical, emotional, and social resources. Psychological first aid is recommended for management of acute stress, while psychological debriefing is discouraged. Further medical and psychiatric assessment and provision of brief, trauma-focused cognitive-behavioral therapy are warranted if clinically significant distress or functional impairment persists or worsens after 2 days or if the criteria for a diagnosis of acute stress disorder are met. Follow-up monitoring and rescreening are endorsed for at least 6 months for everyone who experiences significant acute posttraumatic stress. Four interventions that illustrate early intervention principles contained in the VA/DOD Clinical Practice Guideline are described.

  15. Mentalizing Makes Parenting Work: A Review about Parental Reflective Functioning and Clinical Interventions to Improve It (United States)

    Camoirano, Andrea


    In the last decade several studies have investigated the role of parental reflective functioning (RF), defined as the parental ability to understand his/her child’s mental states, on the child’s development. Herein, a narrative review on parental RF is presented aimed at (1) presenting an overview of the existing empirical studies, (2) pinpointing unrequited questions, and (3) identifying future research directions. Specifically, the current review focused on (a) the impact of parental RF on the quality of caregiving and the child’s attachment security, (b) the effect of parental RF on the child’s emotion regulation and the child’s RF, (c) maternal RF in women with a history of neglect and abuse, (d) the efficacy of mentalization-based clinical interventions, and (e) the recently developed Parental Reflective Questionnaire. The following terms “maternal RF,” “paternal RF,” “parental RF,” “parental mentalization,” “maternal mentalization,” and “paternal mentalization” were searched in titles, abstracts, and main texts using Medline, Web of Science, and Scopus databases. Next, a search in Mendeley was also conducted. Inclusion criteria comprised original articles if they refer to the RF Scale (Fonagy et al., 1998) and were published in an English language, peer-reviewed journal before July, 2016. According to exclusion criteria, dissertations, qualitative or theoretical papers, and chapters in books were not taken into account. The review includes 47 studies that, taken together, supported the notion that higher parental RF was associated with adequate caregiving and the child’s attachment security, whereas low maternal RF was found in mothers whose children suffered from anxiety disorders, impairment in emotion regulation, and externalizing behaviors. In addition, higher parental RF was associated with better mentalizing abilities in children. However, unexpected findings have emerged from the most recent randomized controlled

  16. Clinical improvements in adopted children with fetal alcohol spectrum disorders through neurodevelopmentally informed clinical intervention: A pilot study. (United States)

    Zarnegar, Zohreh; Hambrick, Erin P; Perry, Bruce D; Azen, Stanley P; Peterson, Cassandra


    Research on early intervention for young children (infants and toddlers) with fetal alcohol spectrum disorders (FASD), particularly children with comorbid maltreatment experiences, is limited. Existing research has primarily focused on structuring environments to be responsive to the needs experienced by children with FASD rather than improving their functioning. The purpose of this study is to present outcomes from an early psychosocial intervention with 10 adopted, maltreated young children diagnosed with FASD, aged 10-53 months (M = 35 months), and their adoptive parents. The potential for early, targeted interventions to improve developmental outcomes for children with prenatal alcohol exposure was examined, as well as improving the skills of and reducing stress experienced by their adoptive parents. Based on the outcomes of a neurodevelopmentally informed assessment protocol, the 10 children whose data are presented were recommended to receive a range of regulatory, somatosensory, relational, and cognitive enrichments. As part of their treatment, children and caregivers received Child-Parent Psychotherapy (CPP), and caregivers (here, adoptive parents) also received Mindful Parenting Education (MPE). Related-samples Wilcoxon signed-rank tests indicated that scores of several measures of child developmental functioning improved from pre- to post-intervention and that parents' caregiving skills improved while their caregiving stress decreased. Reliable change analyses indicated that change observed from pre- to post-intervention was reliable. The promise of using neurodevelopmentally informed assessment strategies to sequence interventions for young children with diverse neurodevelopmental insults is discussed.

  17. Multispectral photoacoustic imaging of nerves with a clinical ultrasound system (United States)

    Mari, Jean Martial; West, Simeon; Beard, Paul C.; Desjardins, Adrien E.


    Accurate and efficient identification of nerves is of great importance during many ultrasound-guided clinical procedures, including nerve blocks and prostate biopsies. It can be challenging to visualise nerves with conventional ultrasound imaging, however. One of the challenges is that nerves can have very similar appearances to nearby structures such as tendons. Several recent studies have highlighted the potential of near-infrared optical spectroscopy for differentiating nerves and adjacent tissues, as this modality can be sensitive to optical absorption of lipids that are present in intra- and extra-neural adipose tissue and in the myelin sheaths. These studies were limited to point measurements, however. In this pilot study, a custom photoacoustic system with a clinical ultrasound imaging probe was used to acquire multi-spectral photoacoustic images of nerves and tendons from swine ex vivo, across the wavelength range of 1100 to 1300 nm. Photoacoustic images were processed and overlaid in colour onto co-registered conventional ultrasound images that were acquired with the same imaging probe. A pronounced optical absorption peak centred at 1210 nm was observed in the photoacoustic signals obtained from nerves, and it was absent in those obtained from tendons. This absorption peak, which is consistent with the presence of lipids, provides a novel image contrast mechanism to significantly enhance the visualization of nerves. In particular, image contrast for nerves was up to 5.5 times greater with photoacoustic imaging (0.82 +/- 0.15) than with conventional ultrasound imaging (0.148 +/- 0.002), with a maximum contrast of 0.95 +/- 0.02 obtained in photoacoustic mode. This pilot study demonstrates the potential of photoacoustic imaging to improve clinical outcomes in ultrasound-guided interventions in regional anaesthesia and interventional oncology.

  20. Low omega-6 vs. low omega-6 plus high omega-3 dietary intervention for Chronic Daily Headache: Protocol for a randomized clinical trial

    Directory of Open Access Journals (Sweden)

    Smith Sunyata


    Full Text Available Abstract Background Targeted analgesic dietary interventions are a promising strategy for alleviating pain and improving quality of life in patients with persistent pain syndromes, such as chronic daily headache (CDH. High intakes of the omega-6 (n-6 polyunsaturated fatty acids (PUFAs, linoleic acid (LA and arachidonic acid (AA may promote physical pain by increasing the abundance, and subsequent metabolism, of LA and AA in immune and nervous system tissues. Here we describe methodology for an ongoing randomized clinical trial comparing the metabolic and clinical effects of a low n-6, average n-3 PUFA diet, to the effects of a low n-6 plus high n-3 PUFA diet, in patients with CDH. Our primary aim is to determine if: A both diets reduce n-6 PUFAs in plasma and erythrocyte lipid pools, compared to baseline; and B the low n-6 plus high n-3 diet produces a greater decline in n-6 PUFAs, compared to the low n-6 diet alone. Secondary clinical outcomes include headache-specific quality-of-life, and headache frequency and intensity. Methods Adults meeting the International Classification of Headache Disorders criteria for CDH are included. After a 6-week baseline phase, participants are randomized to a low n-6 diet, or a low n-6 plus high n-3 diet, for 12 weeks. Foods meeting nutrient intake targets are provided for 2 meals and 2 snacks per day. A research dietitian provides intensive dietary counseling at 2-week intervals. Web-based intervention materials complement dietitian advice. Blood and clinical outcome data are collected every 4 weeks. Results Subject recruitment and retention has been excellent; 35 of 40 randomized participants completed the 12-week intervention. Preliminary blinded analysis of composite data from the first 20 participants found significant reductions in erythrocyte n-6 LA, AA and %n-6 in HUFA, and increases in n-3 EPA, DHA and the omega-3 index, indicating adherence.

  2. Brief intervention for alcohol misuse in people attending sexual health clinics: study protocol for a randomized controlled trial

    Directory of Open Access Journals (Sweden)

    Sanatinia Rahil


    Full Text Available Abstract Background Over the last 30 years the number of people who drink alcohol at harmful levels has increased in many countries. There have also been large increases in rates of sexually transmitted infections. Available evidence suggests that excessive alcohol consumption and poor sexual health may be linked. The prevalence of harmful alcohol use is higher among people attending sexual health clinics than in the general population, and a third of those attending clinics state that alcohol use affects whether they have unprotected sex. Previous research has demonstrated that brief intervention for alcohol misuse in other medical settings can lead to behavioral change, but the clinical- and cost-effectiveness of this intervention on sexual behavior have not been examined. Methods We will conduct a two parallel-arm, randomized trial. A consecutive sample of people attending three sexual health clinics in London and willing to participate in the study will be screened for excessive alcohol consumption. Participants identified as drinking excessively will then be allocated to either active treatment (Brief Advice and referral for Brief Intervention or control treatment (a leaflet on healthy living. Randomization will be via an independent and remote telephone randomization service and will be stratified by study clinic. Brief Advice will comprise feedback on the possible health consequences of excessive alcohol consumption, written information about alcohol and the offer of an appointment for further assessment and Brief Intervention. Follow-up data on alcohol use, sexual behavior, health related quality of life and service use will be collected by a researcher masked to allocation status six months later. The primary outcome for the study is mean weekly alcohol consumption during the previous three months, and the main secondary outcome is the proportion of participants who report unprotected sex during this period.

  3. California's digital divide: clinical information systems for the haves and have-nots. (United States)

    Miller, Robert H; D'Amato, Katherine; Oliva, Nancy; West, Christopher E; Adelson, Joel W


    Strong barriers prevent the financing of clinical information systems (CIS) in health care delivery system organizations in market segments serving disadvantaged patients. These segments include community health centers, public hospitals, unaffiliated rural hospitals, and some Medicaid-oriented solo and small-group medical practices. Policy interventions such as loans, grants, pay-for-performance and other reimbursement changes, and support services assistance will help lower these barriers. Without intervention, progress will be slow and worsen health care disparities between the advantaged and disadvantaged populations.

    OBJECTIVE To promote the clinical awareness of cross allergy and prevent the occurrence of medical errors. METHODS Prescribing information on cross allergy in "Contraindications" was derived from a software. Records of drug counseling, cases of medical errors and near misses in an online reporting system were analyzed. Data mining was performed. Clinical pharmacological interventions were conducted and the effects were evaluated. RESULTS Besides 27 kinds of drugs within pharmacologically similar class involving cross allergy, there were seven kinds of drugs with complete different pharmacological effects. Similarity in chemical structures was the main case of cross allergy. Excipients were related with cross allergy. Prescribing information in some drugs had unscientific descriptions on cross allergy associated contraindications, lacking clinical value in guiding safe use of medication. There were difference in descriptions on cross allergy in some drugs within pharmacologically similar clas, and some domestic and imported products. The problem of cross allergy of drugs involving different pharmacological effects was dangerous and not easy to be detected. After pharmacological interventions, awareness was greatly increased and the occurrence rate of medical errors and similar mistake decreased by 97%. CONCLISION Severe potential safety hazard might exist if more attentions are not paid to cross allergy aspect. The comprehensive pharmacological interventions are very effective. Applications of information technology and data maintenance are pivotal for continuous quality improvement in cross allergy aspect.%目的 促进临床医护人员对药物交叉过敏的意识,防范用药失误发生.方法 对药物说明书禁忌症中有关交叉过敏的描述进行信息分析和数据挖掘.对药物咨询、用药失误和近似错误在线呈报系统记录进行分析.实施临床药学综合性干预措施,并评估干预效果.结果 除药理作用相似的27

  9. Peer assisted learning in the clinical setting: an activity systems analysis. (United States)

    Bennett, Deirdre; O'Flynn, Siun; Kelly, Martina


    Peer assisted learning (PAL) is a common feature of medical education. Understanding of PAL has been based on processes and outcomes in controlled settings, such as clinical skills labs. PAL in the clinical setting, a complex learning environment, requires fresh evaluation. Socio-cultural theory is proposed as a means to understand educational interventions in ways that are practical and meaningful. We describe the evaluation of a PAL intervention, introduced to support students' transition into full time clinical attachments, using activity theory and activity systems analysis (ASA). Our research question was How does PAL transfer to the clinical environment? Junior students on their first clinical attachments undertook a weekly same-level, reciprocal PAL activity. Qualitative data was collected after each session, and focus groups (n = 3) were held on completion. Data was analysed using ASA. ASA revealed two competing activity systems on clinical attachment; Learning from Experts, which students saw as the primary function of the attachment and Learning with Peers, the PAL intervention. The latter took time from the first and was in tension with it. Tensions arose from student beliefs about how learning takes place in clinical settings, and the importance of social relationships, leading to variable engagement with PAL. Differing perspectives within the group were opportunities for expansive learning. PAL in the clinical environment presents challenges specific to that context. Using ASA helped to describe student activity on clinical attachment and to highlight tensions and contradictions relating PAL in that setting. Planning learning opportunities on clinical placements, must take account of how students learn in workplaces, and the complexity of the multiple competing activity systems related to learning and social activities.

  10. The immuno-dynamics of conflict intervention in social systems.

    Directory of Open Access Journals (Sweden)

    David C Krakauer

    Full Text Available We present statistical evidence and dynamical models for the management of conflict and a division of labor (task specialization in a primate society. Two broad intervention strategy classes are observed--a dyadic strategy--pacifying interventions, and a triadic strategy--policing interventions. These strategies, their respective degrees of specialization, and their consequences for conflict dynamics can be captured through empirically-grounded mathematical models inspired by immuno-dynamics. The spread of aggression, analogous to the proliferation of pathogens, is an epidemiological problem. We show analytically and computationally that policing is an efficient strategy as it requires only a small proportion of a population to police to reduce conflict contagion. Policing, but not pacifying, is capable of effectively eliminating conflict. These results suggest that despite implementation differences there might be universal features of conflict management mechanisms for reducing contagion-like dynamics that apply across biological and social levels. Our analyses further suggest that it can be profitable to conceive of conflict management strategies at the behavioral level as mechanisms of social immunity.

  11. A randomized controlled clinical trial of a nurse-led structured psychosocial intervention program for people with first-onset mental illness in psychiatric outpatient clinics. (United States)

    Chien, Wai-Tong; Bressington, Daniel


    This study aimed to test the effectiveness of a nurse-led structured psychosocial intervention program in Chinese patients with first-onset mental illness. A single-blind, parallel group, randomized controlled trial design was used. The study involved 180 participants with mild to moderate-severe symptoms of psychotic or mood disorders who were newly referred to two psychiatric outpatient clinics in Hong Kong. Patients were randomly assigned to either an eight-session nurse-led psychosocial intervention program (plus usual care) or usual psychiatric outpatient care (both n=90). The primary outcome was psychiatric symptoms. Outcomes were measured at recruitment, one week and 12 months post-intervention. Patients in the psychosocial intervention group reported statistically significant improvements in symptoms compared to treatment as usual. There were also significant improvements in illness insight and perceived quality of life and reduction in length of re-hospitalizations over the 12-month follow-up. The findings provide evidence that the nurse-led psychosocial intervention program resulted in improved health outcomes in Chinese patients with first-onset mental illness.

    Full Text Available ABSTRACT Objective: to evaluate the effectiveness of the telephone intervention for promoting self-care related to physical activity and following a diet plan in users with diabetes, compared to conventional monitoring of users over a six-month period. Method: this was a randomized clinical trial, which included 210 users with diabetes, linked to eight Primary Health Units of Belo Horizonte, Minas Gerais. The experimental group (104 members received six telephone interventions over the six-month monitoring; the control group (106 members received conventional monitoring. To evaluate the self-care practices related to physical activity and following a healthy eating plan, in both groups, the self-care questionnaire was applied before the intervention and at three and six months after its start. Results: the mean effect of self-care scores in the experimental group was 1.03 to 1.78 higher than the control group, with progressive and significant improvement (p<0.001. Conclusion: the results indicate that the telephone intervention had a beneficial effect on diabetes self-care. The primary identifier of the clinical trials registry was: RBR-8wx7qb.

  13. Liposomal drug delivery systems--clinical applications. (United States)

    Goyal, Parveen; Goyal, Kumud; Vijaya Kumar, Sengodan Gurusamy; Singh, Ajit; Katare, Om Prakash; Mishra, Dina Nath


    Liposomes have been widely investigated since 1970 as drug carriers for improving the delivery of therapeutic agents to specific sites in the body. As a result, numerous improvements have been made, thus making this technology potentially useful for the treatment of certain diseases in the clinics. The success of liposomes as drug carriers has been reflected in a number of liposome-based formulations, which are commercially available or are currently undergoing clinical trials. The current pharmaceutical preparations of liposome-based therapeutic systems mainly result from our understanding of lipid-drug interactions and liposome disposition mechanisms. The insight gained from clinical use of liposome drug delivery systems can now be integrated to design liposomes that can be targeted on tissues, cells or intracellular compartments with or without expression of target recognition molecules on liposome membranes. This review is mainly focused on the diseases that have attracted most attention with respect to liposomal drug delivery and have therefore yielded most progress, namely cancer, antibacterial and antifungal disorders. In addition, increased gene transfer efficiencies could be obtained by appropriate selection of the gene transfer vector and mode of delivery.

  14. System for clinical photometric stereo endoscopy (United States)

    Durr, Nicholas J.; González, Germán.; Lim, Daryl; Traverso, Giovanni; Nishioka, Norman S.; Vakoc, Benjamin J.; Parot, Vicente


    Photometric stereo endoscopy is a technique that captures information about the high-spatial-frequency topography of the field of view simultaneously with a conventional color image. Here we describe a system that will enable photometric stereo endoscopy to be clinically evaluated in the large intestine of human patients. The clinical photometric stereo endoscopy system consists of a commercial gastroscope, a commercial video processor, an image capturing and processing unit, custom synchronization electronics, white light LEDs, a set of four fibers with diffusing tips, and an alignment cap. The custom pieces that come into contact with the patient are composed of biocompatible materials that can be sterilized before use. The components can then be assembled in the endoscopy suite before use. The resulting endoscope has the same outer diameter as a conventional colonoscope (14 mm), plugs into a commercial video processor, captures topography and color images at 15 Hz, and displays the conventional color image to the gastroenterologist in real-time. We show that this system can capture a color and topographical video in a tubular colon phantom, demonstrating robustness to complex geometries and motion. The reported system is suitable for in vivo evaluation of photometric stereo endoscopy in the human large intestine.

    Ndebele Paul M


    Full Text Available Abstract Background The intervention reported in this paper was a follow up to an empirical study conducted in Malawi with the aim of assessing trial participants’ understanding of randomisation, double-blinding and placebo use. In the empirical study, the majority of respondents (61.1%; n=124 obtained low scores (lower than 75% on understanding of all three concepts under study. Based on these findings, an intervention based on a narrative which included all three concepts and their personal implications was designed. The narrative used daily examples from the field of Agriculture because Malawi has an agro-based economy. Methods The intervention was tested using a sample of 36 women who had been identified as low scorers during the empirical study. The 36 low scorers were randomly assigned to control (n=18 and intervention arms (n=18. The control arm went through a session in which they were provided with standard informed consent information for the microbicide trial. The intervention arm went through a session in which they were provided with a narrative in ChiChewa, the local language, with the assistance of a power point presentation which included pictures as well as discussions on justification and personal implications of the concepts under study. Results The findings on the efficacy of the intervention suggest that the 3 scientific concepts and their personal implications can be understood by low literacy populations using simple language and everyday local examples. The findings also suggest that the intervention positively impacted on understanding of trial procedures under study, as 13 of the 18 women in the intervention arm, obtained high scores (above 75% during the post intervention assessment and none of the 18 in the control arm obtained a high score. Using Fischer’s exact test, it was confirmed that the effect of the intervention on understanding of the three procedures was statistically significant (p=0.0001. Conclusions

  17. The Radiologist Is in, but Was it Worth the Wait? Radiology Resident Note Quality in an Outpatient Interventional Radiology Clinic. (United States)

    Abboud, Salim E; Soriano, Stephanie; Abboud, Rayan; Patel, Indravadan; Davidson, Jon; Azar, Nami R; Nakamoto, Dean A


    Preprocedural evaluation of patients in an interventional radiology (IR) clinic is a complex synthesis of physical examination and imaging findings, and as IR transitions to an independent clinical specialty, such evaluations will become an increasingly critical component of a successful IR practice and quality patient care. Prior research suggests that preprocedural evaluations increased patient's perceived quality of care and may improve procedural technical success rates. Appropriate documentation of a preprocedural evaluation in the medical record is also paramount for an interventional radiologist to add value and function as an effective member of a larger IR service and multidisciplinary health care team. The purpose of this study is to examine the quality of radiology resident notes for patients seen in an outpatient IR clinic at a single academic medical center before and after the adoption of clinic note template with reminders to include platelet count, international normalized ratio, glomerular filtration rate, and plan for periprocedural coagulation status. Before adoption of the template, platelet count, international normalized ratio, glomerular filtration rate and an appropriate plan for periprocedural coagulation status were documented in 72%, 82%, 42%, and 33% of patients, respectively. After adoption of the template, appropriate documentation of platelet count, international normalized ratio, and glomerular filtration rate increased to 96%, and appropriate plan for periprocedural coagulation status was documented in 83% of patients. Patient evaluation and clinical documentation skills may not be adequately practiced during radiology residency, and tools such as templates may help increase documentation quality by radiology residents.

  18. Acute inpatient palliative medicine in a cancer center: clinical problems and medical interventions--a prospective study. (United States)

    Lagman, Ruth; Rivera, Nilo; Walsh, Declan; LeGrand, Susan; Davis, Mellar P


    The clinical characteristics and medical interventions of the 100 consecutive cancer admissions to the acute care inpatient palliative medicine unit at the Cleveland Clinic for 2 months are described. Median age was 62 years (range, 31 to 92 years). The male-female ratio was 1:1. Most admissions were referred by hematology-oncology and had prior antineoplastic therapy. Reasons for admission were symptom control and cancer-related complications. Patients underwent invasive diagnostic and therapeutic procedures, hydration, transfusions, radiation, or chemotherapy, or a combination, during their admission. Most were discharged home with hospice care or had outpatient clinic follow-up. The mortality rate was 20%. Aggressive multidisciplinary management of symptoms, disease complications, comorbid conditions, and psychosocial problems were provided. Palliative medicine physicians provided continuity of care in the outpatient clinic and at home. An acute inpatient palliative medicine unit within a tertiary level medical center has a definable and important role in comprehensive cancer care.

  19. Brief Interventions implementation on alcohol from the European health systems perspective

    Directory of Open Access Journals (Sweden)

    Joan eColom


    Full Text Available Alcohol related health problems are important public health issues and alcohol remains one of the leading risk factors of chronic health conditions. In addition, only a small proportion of those who need treatment access it, with figures ranging from 1 in 25 to 1 in 7. In this context, Screening and Brief Interventions (SBI have proven to be effective in reducing alcohol consumption and alcohol related problems in primary health care (PHC and are very cost effective, or even cost-saving, in PHC. Even if the widespread implementation of SBI has been prioritized and encouraged by the WHO, in the global alcohol strategy, the evidence on long term and population level effects is still weak. This review study will summarize the SBI programs implemented by six European countries with different socio-economic contexts. Similar components at health professional level but differences at organizational level, especially on the measures to support clinical practice, incentives and monitoring systems developed were adopted. In Italy cost-effectiveness analyses and Internet trials shed new light on limits and facilitators of renewed, evidence-based approaches to better deal with brief intervention in PHC. The majority of the efforts were aimed at overcoming individual barriers and promoting health professionals’ involvement. The population screened have been in general too low to be able to detect any population level effect, with a negative impact on the acceptability of the program to all stakeholders.This paper will present a different point of view based on a strategic broadening of the implemented actions to real inter-sectoriality and a wider holistic approach. Effective alcohol policies should strive for quality provision of Health Services (HS and the empowerment of the individuals in a Health System (HSys approach.

  20. [Quality control an assessment system. Its location within a program for food, nutrition and metabolic intervention]. (United States)

    Santana Porbén, S


    A design proposal for a HQCAS Hospital Quality Control and Assessment System of the nutritional and feeding care processes conducted in a hospital environment is presented in this article. The design proposal is accompanied of the results of inspections conducted by the hospital NST Nutritional Support Group between 2005-2010. The system design includes quality policies that should rule the useful and safe conduction of such processes, the recording and documentary foundations of the System, and the quality control and assessment exercises for the continuous verification of such established policies. The current state of the conduction of these processes was documented from secondary records opened by the NST after satisfying consultation requests from the medical care teams of the institution. Inspections conducted by the NST revealed that less than half of clinical charts contained information minimally enough for elaborating nutritional judgments, almost one-fifth of the assisted patients were on Nils Per Oris, for whom no nutritional support schemes were prescribed, and a low prescription and usage of artificial nutrition schemes. Corrective measures adopted by the NST served to significantly increase the rates of successful completion of inspected processes. Quality assurance of feeding and nutritional care processes is a practical as well as an intellectual activity subjected to constant remodeling, in order to always warrant the fulfillment of quality policies advanced by the NST, and thus, that the patient benefits from the prescribed nutritional intervention strategy.

  1. Health effects of mixed fruit and vegetable concentrates: a systematic review of the clinical interventions. (United States)

    Esfahani, Amin; Wong, Julia M W; Truan, Jennifer; Villa, Christopher R; Mirrahimi, Arash; Srichaikul, Korbua; Kendall, Cyril W C


    Diets rich in fruits and vegetables (FV) have been associated with a reduced risk of chronic disease, including cardiovascular disease. Unfortunately, public health campaigns to increase FV intake have had limited success. A number of mixed concentrated FV products have been studied, which may help certain individuals improve nutrient status. However, the possible health benefits of FV supplements have not been systematically reviewed. We, therefore, undertook a systematic search of MEDLINE and EMBASE to identify clinical interventions that examined the effect of commercially available concentrated mixed FV supplements on cardiovascular disease risk factors. Twenty-two reports, which used commercially available products, were identified. None of the studies reported any serious adverse effects. Overall, daily consumption of FV supplements significantly increased serum concentrations of the major antioxidant provitamins and vitamins found in plant foods (β-carotene, vitamins C and E) and folate. Functional changes, such as reduced serum homocysteine and markers of protein, lipid, and DNA oxidation, were also reported; in addition, the health advantages on markers of inflammation, immunity, and endothelial function are promising. Limitations of the available studies were related to the diversity of studies conducted with respect to design and study population and the variability in the measured outcomes and assays utilized. While mixed FV supplements may serve as an efficacious complement for individuals who have difficulty achieving their daily FV intake requirement, further research on additional retail preparations is warranted. Key teaching points: Mixed fruit and vegetable supplements produced from plant foods may serve as an efficacious complement to the habitual diet in individuals who have suboptimal intake or variety of nutrient-dense fruits and vegetables. Current research indicates that fruit and vegetable concentrates significantly increase serum levels

  2. Memory Interventions in the Criminal Justice System: Some Practical Ethical Considerations. (United States)

    Cabrera, Laura Y; Elger, Bernice S


    In recent years, discussion around memory modification interventions has gained attention. However, discussion around the use of memory interventions in the criminal justice system has been mostly absent. In this paper we start by highlighting the importance memory has for human well-being and personal identity, as well as its role within the criminal forensic setting; in particular, for claiming and accepting legal responsibility, for moral learning, and for retribution. We provide examples of memory interventions that are currently available for medical purposes, but that in the future could be used in the forensic setting to modify criminal offenders' memories. In this section we contrast the cases of (1) dampening and (2) enhancing memories of criminal offenders. We then present from a pragmatic approach some pressing ethical issues associated with these types of memory interventions. The paper ends up highlighting how these pragmatic considerations can help establish ethically justified criteria regarding the possibility of interventions aimed at modifying criminal offenders' memories.

    Bernardi, Maria-Pia; Ngan, Samuel Y; Michael, Michael; Lynch, A Craig; Heriot, Alexander G; Ramsay, Robert G; Phillips, Wayne A


    Anal squamous cell carcinoma is a human papillomavirus-related disease, in which no substantial advances in treatment have been made in over 40 years, especially for those patients who develop disease relapse and for whom no surgical options exist. HPV can evade the immune system and its role in disease progression can be exploited in novel immunotherapy platforms. Although several studies have investigated the expression and inactivation (through loss of heterozygosity) of tumour suppressor genes in the pathways to cancer, no clinically valuable biomarkers have emerged. Regulators of apoptosis, including survivin, and agents targeting the PI3K/AKT pathway, offer opportunities for targeted therapy, although robust data are scarce. Additionally, antibody therapy targeting EGFR may prove effective, although its safety profile in combination with standard chemoradiotherapy has proven to be suboptimal. Finally, progress in the treatment of anal cancer has remained stagnant due to a lack of preclinical models, including cell lines and mouse models. In this Review, we discuss the molecular biology of anal squamous cell carcinoma, clinical trials in progress, and implications for novel therapeutic targets. Future work should focus on preclinical models to provide a resource for investigation of new molecular pathways and for testing novel targets.

  4. [Digital photograph storage systems in clinical dermatology]. (United States)

    Taberner, R; Contestí, T


    In recent years, digital photography has consolidated its role in clinical dermatology. In view of the quality and low cost of current equipment and the simplicity of digital storage, almost all dermatologists now use digital photography, which is also extremely versatile and readily applicable to teaching. However, to maximize its full potential, image retrieval must be available at any time and with the patient present. This requires a suitable storage system that may vary according to the characteristics of each center. Dermatologists must also find time to maintain and organize the digital archives. The present article describes current options in digital image storage and retrieval, ranging from multidepartmental picture archiving and communication systems at one end to image management freeware at the other, and also including dedicated dermatology software.

  8. Evidence-based clinical practice guidelines for interventional pain management in cancer pain

    Directory of Open Access Journals (Sweden)

    Sushma Bhatnagar


    Full Text Available Intractable cancer pain not amenable to standard oral or parenteral analgesics is a horrifying truth in 10-15% of patients. Interventional pain management techniques are an indispensable arsenal in pain physician′s armamentarium for severe, intractable pain and can be broadly classified into neuroablative and neuromodulation techniques. An array of neurolytic techniques (chemical, thermal, or surgical can be employed for ablation of individual nerve fibers, plexuses, or intrathecalneurolysis in patients with resistant pain and short life-expectancy. Neuraxial administration of drugs and spinal cord stimulation to modulate or alter the pain perception constitutes the most frequently employed neuromodulation techniques. Lately, there is a rising call for early introduction of interventional techniques in carefully selected patients simultaneously or even before starting strong opioids. After decades of empirical use, it is the need of the hour to head towards professionalism and standardization in order to secure credibility of specialization and those practicing it. Even though the interventional management has found a definite place in cancer pain, there is a dearth of evidence-based practice guidelines for interventional therapies in cancer pain. This may be because of paucity of good quality randomized controlled trials (RCTs evaluating their safety and efficacy in cancer pain. Laying standardized guidelines based on existing and emerging evidence will act as a foundation step towards strengthening, credentialing, and dissemination of the specialty of interventional cancer pain management. This will also ensure an improved decision-making and quality of life (QoL of the suffering patients.

  9. Burnout hazard in teachers results of a clinical-psychological intervention study

    Directory of Open Access Journals (Sweden)

    Wegner Ralf


    Full Text Available Abstract Background The study investigates whether established in-patient therapy for teachers with burnout results in long-acting success and whether gender gaps and differences between teachers of different school levels exist. According to our knowledge, our study is the most extensive inpatient intervention study on the burnout of a defined occupational group, i.e., teachers. Methods 200 teachers participated, 150 took part in a later performed katamnestic survey. The Maslach Burnout Inventory (MBI was used and work-related data were recorded. The days of incapacity for work and the percentage of teachers endangered by burnout decreased, which supports the long-term success of the treatment. Results Significant differences between males and females and between teacher levels were found. However, the differences between teacher levels only showed up before treatment. Because males only underwent treatment at a more severe stage, further efforts in persuading males to start therapy earlier are needed. Conclusions The proven and long-term success of the performed intervention could have greater effects if people, especially males, undergo treatment more frequently. Our results are based on selectively high proposition of teachers of advanced age. Thus it is possible that the long term effect of the intervention, particularly on retirement age, is greater when the intervention is started earlier. Regular burnout tests could help to identify risk cases among teachers at an early stage and to offer a therapeutic intervention.

  10. Clinical trials to estimate the efficacy of preventive interventions against malaria in paediatric populations: a methodological review

    Directory of Open Access Journals (Sweden)

    Reed Zarifah


    Full Text Available Abstract Background Recent years have seen publication of a considerable number of clinical trials of preventive interventions against clinical malaria in children. There has been variability in the specification of end-points, case definitions, analysis methods and reporting and the relative lack of standardization complicates the ability to make comparative evaluations between trials. Methods To prepare for a WHO consultation on design issues in malaria vaccine trials, controlled trials of preventive interventions against malaria in children in endemic countries were identified in which clinical malaria, or death, had been one of the main end-points. Trials were included that evaluated the impact of vaccines, insecticide-treated bed nets (ITN, intermittent presumptive or preventive therapy in infants (IPTi or, in one instance, vitamin A supplementation. Methods that had been used in these trials were summarized and compared in order to identify issues that were directly relevant to the design of malaria vaccine trials. Results 29 controlled trials of preventive malaria interventions were identified, of which eight were vaccine trials. Vaccine trials that were designed to detect an effect on clinical malaria all reported the incidence rate of first episodes of clinical malaria as their primary endpoint. Only one trial of a preventive intervention (of ITN was identified that was designed to detect an effect on severe malaria. A group of larger trials were designed to detect an effect of impregnated bed nets or curtains on all-cause mortality as the primary end-point. Key methodological and reporting differences between trials are noted in the text. Two issues have been identified that are of some concern. Firstly, the choice of primary endpoint is not stated in the reports of a number of the trials and, secondly, the relationship between pre-specified analysis plans and trial reports is rarely made clear. Conclusion This article reports an

    Cobbe, S M


    The clinical usefulness of the Vaughan Williams classification scheme is limited by the complexity of the mechanisms of arrhythmia formation in man, which offer multiple potential sites for intervention. The properties of antiarrhythmic drugs may be considerably altered in abnormal myocardium. Despite these limitations, however, the classification provides a valuable conceptual framework for the understanding of the clinical electrophysiological properties of antiarrhythmic drugs and for their use.

  14. A navigation system for percutaneous needle interventions based on PET/CT images: design, workflow and error analysis of soft tissue and bone punctures. (United States)

    Oliveira-Santos, Thiago; Klaeser, Bernd; Weitzel, Thilo; Krause, Thomas; Nolte, Lutz-Peter; Peterhans, Matthias; Weber, Stefan


    Percutaneous needle intervention based on PET/CT images is effective, but exposes the patient to unnecessary radiation due to the increased number of CT scans required. Computer assisted intervention can reduce the number of scans, but requires handling, matching and visualization of two different datasets. While one dataset is used for target definition according to metabolism, the other is used for instrument guidance according to anatomical structures. No navigation systems capable of handling such data and performing PET/CT image-based procedures while following clinically approved protocols for oncologic percutaneous interventions are available. The need for such systems is emphasized in scenarios where the target can be located in different types of tissue such as bone and soft tissue. These two tissues require different clinical protocols for puncturing and may therefore give rise to different problems during the navigated intervention. Studies comparing the performance of navigated needle interventions targeting lesions located in these two types of tissue are not often found in the literature. Hence, this paper presents an optical navigation system for percutaneous needle interventions based on PET/CT images. The system provides viewers for guiding the physician to the target with real-time visualization of PET/CT datasets, and is able to handle targets located in both bone and soft tissue. The navigation system and the required clinical workflow were designed taking into consideration clinical protocols and requirements, and the system is thus operable by a single person, even during transition to the sterile phase. Both the system and the workflow were evaluated in an initial set of experiments simulating 41 lesions (23 located in bone tissue and 18 in soft tissue) in swine cadavers. We also measured and decomposed the overall system error into distinct error sources, which allowed for the identification of particularities involved in the process as well

    BACKGROUND Men who have sex with men (MSM) experience significant inequalities in health and well-being. They are the group in the UK at the highest risk of acquiring a human immunodeficiency virus (HIV) infection. Guidance relating to both HIV infection prevention, in general, and individual-level behaviour change interventions, in particular, is very limited. OBJECTIVES To conduct an evidence synthesis of the clinical effectiveness of behaviour change interventions to reduce risky sexual behaviour among MSM after a negative HIV infection test. To identify effective components within interventions in reducing HIV risk-related behaviours and develop a candidate intervention. To host expert events addressing the implementation and optimisation of a candidate intervention. DATA SOURCES All major electronic databases (British Education Index, BioMed Central, Cumulative Index to Nursing and Allied Health Literature, EMBASE, Educational Resource Index and Abstracts, Health and Medical Complete, MEDLINE, PsycARTICLES, PsycINFO, PubMed and Social Science Citation Index) were searched between January 2000 and December 2014. REVIEW METHODS A systematic review of the clinical effectiveness of individual behaviour change interventions was conducted. Interventions were examined using the behaviour change technique (BCT) taxonomy, theory coding assessment, mode of delivery and proximity to HIV infection testing. Data were summarised in narrative review and, when appropriate, meta-analysis was carried out. Supplemental analyses for the development of the candidate intervention focused on post hoc realist review method, the assessment of the sequential delivery and content of intervention components, and the social and historical context of primary studies. Expert panels reviewed the candidate intervention for issues of implementation and optimisation. RESULTS Overall, trials included in this review (n = 10) demonstrated that individual-level behaviour change interventions

  16. Healthcare information systems: data mining methods in the creation of a clinical recommender system (United States)

    Duan, L.; Street, W. N.; Xu, E.


    Recommender systems have been extensively studied to present items, such as movies, music and books that are likely of interest to the user. Researchers have indicated that integrated medical information systems are becoming an essential part of the modern healthcare systems. Such systems have evolved to an integrated enterprise-wide system. In particular, such systems are considered as a type of enterprise information systems or ERP system addressing healthcare industry sector needs. As part of efforts, nursing care plan recommender systems can provide clinical decision support, nursing education, clinical quality control, and serve as a complement to existing practice guidelines. We propose to use correlations among nursing diagnoses, outcomes and interventions to create a recommender system for constructing nursing care plans. In the current study, we used nursing diagnosis data to develop the methodology. Our system utilises a prefix-tree structure common in itemset mining to construct a ranked list of suggested care plan items based on previously-entered items. Unlike common commercial systems, our system makes sequential recommendations based on user interaction, modifying a ranked list of suggested items at each step in care plan construction. We rank items based on traditional association-rule measures such as support and confidence, as well as a novel measure that anticipates which selections might improve the quality of future rankings. Since the multi-step nature of our recommendations presents problems for traditional evaluation measures, we also present a new evaluation method based on average ranking position and use it to test the effectiveness of different recommendation strategies.

  17. New Medicine for the U.S. Health Care System: Training Physicians for Structural Interventions. (United States)

    Hansen, Helena; Metzl, Jonathan M


    Structural competency provides a language and theoretical framework to promote institutional-level interventions by clinical practitioners working with community organizations, non-health-sector institutions, and policy makers. The special collection of articles on structural competency in this issue of Academic Medicine addresses the need to move from theory to an appraisal of core educational interventions that operationalize the goals of and foster structural competency. In this Commentary, the authors review the role of clinical practitioners in enhancing population-level health outcomes through collaborations with professionals in fields outside medicine, including the social sciences and law. They describe the core elements of structural competency in preclinical and clinical education, as illustrated by the articles of this special collection: perceiving the structural causes of patients' disease, envisioning structural interventions, and cultivating alliances with non-health-sector agencies that can implement structural interventions. Finally, the authors argue that preparing trainees to form partnerships will empower them to influence the social determinants of their patients' health and reduce health inequalities.

  18. A systematic review and meta-analysis of clinical trials on physical interventions for lateral epicondylalgia. (United States)

    Bisset, L; Paungmali, A; Vicenzino, B; Beller, E


    A systematic review of the literature on the effectiveness of physical interventions for lateral epicondylalgia (tennis elbow) was carried out. Seventy six randomised controlled trials were identified, 28 of which satisfied the minimum criteria for meta-analysis. The evidence suggests that extracorporeal shock wave therapy is not beneficial in the treatment of tennis elbow. There is a lack of evidence for the long term benefit of physical interventions in general. However, further research with long term follow up into manipulation and exercise as treatments is indicated.

  19. Clinical significance of scoring system for systemic inflammatory response syndrome

    HAN Jian; LIANG Hua-ping


    The concepts of systemic inflammatory response syndrome (SIRS) and scoring system were defined by the journal of Bone in 1992. SIRS was described as occurrence of two or more clinical criteria in four ones (fever or hypothermia, tachypnea, tachycardia, and leukocytosis).An early diagnosis and estimation of systemic inflammation in patients is helpful for treatment selection. This paper reviews the application of SIRS scoring system, which has been extensively validated for large groups of critical care patients with severe injury and critical surgical diseases.Recent studies have documented SIRS score as a significant predictive parameter of adverse outcome in critical care patients. Furthermore, some studies also give us a suggestion on how to reduce the overload systemic response.

  3. Clinical applications of plasma based electrosurgical systems (United States)

    Woloszko, Jean; Endler, Ashley; Ryan, Thomas P.; Stalder, Kenneth R.


    Over the past 18 years, several electrosurgical systems generating a low temperature plasma in an aqueous conductive solution have been commercialized for various clinical applications and have been used in over 10 million patients to date. The most popular utilizations are in arthroscopic surgery, otorhinolaryngology surgery, spine and neurosurgery, urology and wound care. These devices can be configured to bring saline to the tip and to have concomitant aspiration to remove by-products and excess fluid. By tuning the electrode geometry, waveform and fluid dynamic at the tip of the devices, tissue resection and thermal effects can be adjusted individually. This allows one to design products that can operate as precise tissue dissectors for treatment of articular cartilage or debridement of chronic wounds, as well as global tissue debulking devices providing sufficient concomitant hemostasis for applications like tonsillectomies. Effects of these plasma based electrosurgical devices on cellular biology, healing response and nociceptive receptors has also been studied in various models. This talk will include a review of the clinical applications, with product descriptions, results and introductory review of some of the research on the biological effects of these devices.

    Electrochemical behavior of dental implant system before and after clinical use (in vivo and in vitro) was researched by using abutment and titanium fixture. To simulate an oral environment, the samples of clinically used and non-used implant systems as a working electrode were exposed to artificial saliva at (36.5±1) ℃. Electrochemical tests were carried out using a potentiostat. After electrochemical test, the corrosion morphology of each sample was investigated by FE-SEM and EDS. The corrosion potential and pitting potential of clinically used implant system are lower than those of non-used implant system, and clinically used implant system exhibits a lower range of passivation, indicating a less degree of inherent resistance against chloride ion. The polarization resistance decreases in the case of clinically used implant system, whereas, Rp for clinically non-used implant system increases compared with clinically used implant system.

    Full Text Available Bruno Bordoni,1,2 Emiliano Zanier2,3 1Department of Cardiology, IRCCS S Maria Nascente, Don Carlo Gnocchi Foundation, Milan, Italy; 2CRESO Osteopathic Centre for Research and Studies, 3EdiAcademy, Milan, Italy Abstract: Every body structure is wrapped in connective tissue, or fascia, creating a structural continuity that gives form and function to every tissue and organ. Currently, there is still little information on the functions and interactions between the fascial continuum and the body system; unfortunately, in medical literature there are few texts explaining how fascial stasis or altered movement of the various connective layers can generate a clinical problem. Certainly, the fascia plays a significant role in conveying mechanical tension, in order to control an inflammatory environment. The fascial continuum is essential for transmitting muscle force, for correct motor coordination, and for preserving the organs in their site; the fascia is a vital instrument that enables the individual to communicate and live independently. This article considers what the literature offers on symptoms related to the fascial system, trying to connect the existing information on the continuity of the connective tissue and symptoms that are not always clearly defined. In our opinion, knowing and understanding this complex system of fascial layers is essential for the clinician and other health practitioners in finding the best treatment strategy for the patient.

  12. An Integrated Intervention for Increasing Clinical Nurses' Knowledge of HIV/AIDS-Related Occupational Safety. (United States)

    He, Liping; Lu, Zhiyan; Huang, Jing; Zhou, Yiping; Huang, Jian; Bi, Yongyi; Li, Jun


    Background: Approximately 35 new HIV (Human Immunodeficiency Virus, HIV) cases and at least 1000 serious infections are transmitted annually to health care workers. In China, HIV prevalence is increasing and nursing personnel are encountering these individuals more than in the past. Contaminated needle-stick injuries represent a significant occupational burden for nurses. Evidence suggests that nurses in China may not fully understand HIV/AIDS (Acquired immunodeficiency syndrome, AIDS) and HIV-related occupational safety. At this time, universal protection precautions are not strictly implemented in Chinese hospitals. Lack of training may place nurses at risk for occupational exposure to blood-borne pathogens. Objectives: To assess the effectiveness of integrated interventions on nurses' knowledge improvement about reducing the risk of occupationally acquired HIV infection. Methods: We audited integrated interventions using 300 questionnaires collected from nurses at the Affiliated Hospital of Xiangnan University, a public polyclinic in Hunan Province. The intervention studied was multifaceted and included appropriate and targeted training content for hospital, department and individual levels. After three months of occupational safety integrated interventions, 234 participants who completed the program were assessed. Results: Of the subjects studied, 94.3% (283/300) were injured one or more times by medical sharp instruments or splashed by body fluids in the last year and 95.3% considered their risk of occupational exposure high or very high. After the intervention, awareness of HIV/AIDS-related knowledge improved significantly (χ² = 86.34, p = 0.00), and correct answers increased from 67.9% to 82.34%. Correct answers regarding risk perception were significantly different between pre-test (54.4%) and post-test (66.6%) (χ² = 73.2, p = 0.00). When coming into contact with patient body fluids and blood only 24.0% of subjects used gloves regularly. The pre

    Most frequent complications in patients with liver cirrhosis are due to portal hypertension. Beside ascites circumvent vessles formate with vasodilatation. Due to counterregulation a secondary hyperaldosteronism develops with release of vasocontrictive agents. If conservative and endoscopic methods fail, indication for building a portosystemic shunt is given. The TIPSS procedure is less invasive than the surgical method of Warren-Shunt, so the radiological intervention has replaced surgery. Reducing the portal pressure by the shunt, the clinical complications change for the better. Still problems are defined as hepatic encephalopathy and right ventricular heart failure. Regular follow up investigations have to be performed to detect complications in the shunt. Using regular clinical and radiological check up TIPSS is of clinical benefit with good long term results. (orig.) [German] Die haeufigsten Komplikationen bei Patienten mit einer Leberzirrhose lassen sich auf das Vorliegen einer portalen Hypertension zurueckfuehren. Neben einer Aszitesbildung kommt es zur Vasodilatation mit Ausbildung portaler Umgehungskreislaeufe, gegenregulatorisch zu einem sekundaeren Hyperaldosteronismus und Ausschuettung vasokonstriktiver Substanzen. Sind mittels konservativer und endoskopischer Methoden die Komplikationen nicht mehr zu beherrschen, ist die Indikation zur Shuntanlage gegeben. Wegen der geringeren Invasivitaet einer TIPSS-Anlage gegenueber der operativen Methode eines Warren-Shunts hat sich die interventionell radiologische Methodik in den letzten Jahren immer mehr durchgesetzt. Durch den mittels Shuntanlage reduzierten Pfortaderdruck kommt es zu einer deutlichen klinischen Besserung der unterschiedlichen Komplikationen. Als klinisch problematische Symptome bei der Shuntanlage sind die hepatische Enzephalopathie und eine Zunahme der Rechtsherzbelastung zu werten. Um Komplikationen im Bereich des Shunts frueh zu erkennen, muss dieser engmaschig kontrolliert werden. Unter

  15. Improving awareness of cancer clinical trials among Hispanic patients and families: audience segmentation decisions for a media intervention. (United States)

    Quinn, Gwendolyn P; McIntyre, Jessica; Gonzalez, Luis E; Antonia, Teresita Muñoz; Antolino, Prado; Wells, Kristen J


    Clinical trials hold great promise for cancer treatment; yet, Hispanic cancer patients have low rates of clinical trial participation. Lack of awareness and knowledge of clinical trials and language barriers may account for low participation rates. Patient education through audiovisual materials can improve knowledge of and attitudes toward clinical trials among Hispanic populations. In this study, 36 Hispanic cancer patients/survivors and caregivers in Florida and Puerto Rico participated in focus groups to aid in developing a Spanish-language DVD and booklet intervention designed to increase knowledge about clinical trials. Focus group results showed (a) low levels of knowledge about clinical trials, (b) uncertainty about why a physician would expect a patient to make a choice about treatment, and (c) desire for family participation in decision making. Respondents expressed various preferences for aspects of the DVD such as showing extended family in the DVD and physician explanations about key terms. On the basis of these preferences, the authors developed a creative brief for a DVD. The content of the DVD was reviewed by Hispanic community leaders and key stakeholders. A final DVD was created, in Spanish, using Hispanic patients and physicians, which contained the information deemed important from the focus groups and stakeholder interviews. The DVD is complete with companion booklet and currently undergoing a randomized control trial.

[Universidad de la Republica, Montevideo (Uruguay). School of Sciences; Duran, A. [Universidad de la Republica, Montevideo (Uruguay). Hospital Dr. Manuel Quintela. Dept. of Cardiology


    The purpose of the present paper is to evaluate interventional radiology x-ray system performance in order to analyze its influence on patient dose. Entrance air kerma rate in fluoroscopy modes and air kerma per image in cine modes were measured at the entrance of PMMA slabs (10 to 30 cm) in two interventional x-ray systems. Air kerma evaluation was performed in all image intensifiers (II) diameters and in all fluoroscopy and cine modes used in the clinical practice with an ionization chamber. High and low contrast resolution was evaluated for all PMMA thickness, II and modes, with two quality image tests (NEMA XR 21 and Leeds TOR-18FG). Significant differences were found in air kerma rate and air kerma per image in both x-ray systems for comparable II and modes. For example, for 24 cm PMMA thickness in fluoroscopic high dose mode, in one x-ray system delivers 0.49 mGy/s and the other one 1.87 mGy/s. However, differences in image quality were not significant. In the same conditions described above, Leeds test showed: 0.032 (low contrast) and 1.25 lp mm (spatial frequency). In addition, when phantom thickness increase, image quality decreases in x-ray systems, but in one of them, the difference is high. Results show that patient dose and image quality depend on the x-ray system characteristics. Due to this it is essential to perform a complete evaluation of the x-ray system in order to help interventional cardiologists (radiologists) to learn possibilities of dose reduction with no lose of image quality.

  19. Developing the clinical components of a complex intervention for a glaucoma screening trial: a mixed methods study

    Directory of Open Access Journals (Sweden)


    Full Text Available Abstract Background Glaucoma is a leading cause of avoidable blindness worldwide. Open angle glaucoma is the most common type of glaucoma. No randomised controlled trials have been conducted evaluating the effectiveness of glaucoma screening for reducing sight loss. It is unclear what the most appropriate intervention to be evaluated in any glaucoma screening trial would be. The purpose of this study was to develop the clinical components of an intervention for evaluation in a glaucoma (open angle screening trial that would be feasible and acceptable in a UK eye-care service. Methods A mixed-methods study, based on the Medical Research Council (MRC framework for complex interventions, integrating qualitative (semi-structured interviews with 46 UK eye-care providers, policy makers and health service commissioners, and quantitative (economic modelling methods. Interview data were synthesised and used to revise the screening interventions compared within an existing economic model. Results The qualitative data indicated broad based support for a glaucoma screening trial to take place in primary care, using ophthalmic trained technical assistants supported by optometry input. The precise location should be tailored to local circumstances. There was variability in opinion around the choice of screening test and target population. Integrating the interview findings with cost-effectiveness criteria reduced 189 potential components to a two test intervention including either optic nerve photography or screening mode perimetry (a measure of visual field sensitivity with or without tonometry (a measure of intraocular pressure. It would be more cost-effective, and thus acceptable in a policy context, to target screening for open angle glaucoma to those at highest risk but for both practicality and equity arguments the optimal strategy was screening a general population cohort beginning at age forty. Conclusions Interventions for screening for open angle

    Kimhi, Einat; Reishtein, Judith L; Cohen, Miri; Friger, Michael; Hurvitz, Nancy; Avraham, Rinat


    This study compared the effect of simulation and clinical experience timing on self-confidence/self-efficacy for the nursing process. Using a randomized, double-crossover design, self-efficacy was measured 3 times. Although self-efficacy was significantly higher at time 1 for students who had clinical experience, there was no difference between the groups at the end of the course (time 2). Thus, simulation increased self-confidence/self-efficacy equivalently if placed either before or after clinical experience.

    Pardo, Joe; Klinker, Kenneth P; Borgert, Samuel J; Butler, Brittany M; Giglio, Patricia G; Rand, Kenneth H


    The purpose of this study was to evaluate the impact of the FilmArray Blood Culture Identification (BCID) Panel on the management of patients with blood cultures growing gram positive cocci and Candida. We retrospectively compared clinical and economic outcomes between patients during the BCID testing period and a matched historical control group before BCID testing was introduced. A total of 84 BCID patients were matched to 252 historical controls. BCID identification of coagulase negative staphylococci contaminants resulted in shorter post-culture length of stay (P historical controls (P = 0.047). The BCID, coupled with antimicrobial stewardship intervention, was a cost effective tool to improve patient care.

  4. A randomized clinical trial of the effectiveness of premarital intervention: moderators of divorce outcomes. (United States)

    Markman, Howard J; Rhoades, Galena K; Stanley, Scott M; Peterson, Kristina M


    This study examined the effects of premarital relationship intervention on divorce during the first 8 years of first marriage. Religious organizations were randomly assigned to have couples marrying through them complete the Prevention and Relationship Education Program (PREP) or their naturally occurring premarital services. Results indicated no differences in overall divorce rates between naturally occurring services (n = 44), PREP delivered by clergy at religious organizations (n = 66), or PREP delivered by professionals at a university (n = 83). Three moderators were also tested. Measured premaritally and before intervention, the level of negativity of couples' interactions moderated effects. Specifically, couples observed to have higher levels of negative communication in a video task were more likely to divorce if they received PREP than if they received naturally occurring services; couples with lower levels of premarital negative communication were more likely to remain married if they received PREP. A history of physical aggression in the current relationship before marriage and before intervention showed a similar pattern as a moderator, but the effect was only marginally significant. Family-of-origin background (parental divorce and/or aggression) was not a significant moderator of prevention effects across the two kinds of services. Implications for defining risk, considering divorce as a positive versus negative outcome, the practice of premarital relationship education, and social policy are discussed.

    Therapeutic assessment (TA) aims to affect change in a client, in part, through an in vivo intervention using any number of assessment methods during a planned assessment intervention session (AIS). To date, neuropsychological tests have not been widely used in AIS. We suggest that the Rey-Osterrieth Complex Figure Test (RCFT) can be a helpful tool, especially when the assessment questions pertain to cognitive functioning, owing to its complexity and the fact that it taps several different cognitive functions. To illustrate this, we present the case of Mr. B, a 45-year-old man with a childhood history of neglect and abuse who was struggling with mood and cognitive complaints in the context of identifying a satisfying career. His performance on the RCFT had illuminated his cognitive style, and an AIS was built around observing and changing his approach to problem solving in the context of a supportive relationship. Based on the intervention, he was able to reassess his narrative of cognitive dysfunction, address his problems in organization, and practice using another person for support in problem solving.

    Randomized clinical trials (RCTs) are considered the gold standard for evidence-based medicine. However, an accurate estimation of the event rate is crucial for their ability to test clinical hypotheses. Overestimation of event rates reduces the required sample size but can compromise the statistica

  7. A systematic method to document population-level nursing interventions in an electronic health system. (United States)

    Baisch, Mary Jo


    Many public health electronic health systems lack the specificity to distinguish between individual- and population-based levels of care provided by public health nurses. Data that describe the broad scope of the everyday practice of public health nurses are critical to providing evidence of their effectiveness in promoting community health, which may not be fully appreciated in an arena of scarce resources. This article describes a method to document population-based nursing practice by adding population-based interventions to the nursing taxonomy underlying an electronic health information system. These interventions, derived from the Intervention Wheel, were incorporated into the Omaha System taxonomy, the conceptual framework for the Automated Community Health Information System (ACHIS), which is a longstanding data system used to capture nursing practice in community nursing centers. This article includes a description of the development and testing of the system's ability to capture the practice of the district public health nurse model. This method of adapting an existing data system to capture population-based interventions could be replicated by public health administrators interested in better evaluating the processes and outcomes of public health nursing and other public health professionals.

  8. Substance abuse interventions for parents involved in the child welfare system: evidence and implications. (United States)

    Osterling, Kathy Lemon; Austin, Michael J


    As child welfare systems across the country face the problem of parental substance abuse, there is an increasing need to understand the types of treatment approaches that are most effective for substance-abusing parents in the child welfare system-the majority of whom are mothers. This structured review of the literature focuses on evidence related to two areas: (1) individual-level interventions designed to assist mothers and women in addressing their substance abuse problems, and (2) system-level interventions designed to improve collaboration and coordination between the child welfare system and the alcohol and other drug system. Overall, research suggests the following program components may be effective with substance-abusing women with children: (1) Women-centered treatment that involves children, (2) Specialized health and mental health services, (3) Home visitation services, (4) Concrete assistance, (5) Short-term targeted interventions, and (6) Comprehensive programs that integrate many of these components. Research also suggests that promising collaborative models between the child welfare system (CWS) and the alcohol and other drug (AOD) system typically include the following core elements: (1) Out-stationing AOD workers in child welfare offices, (2) Joint case planning, (3) Using official committees to guide collaborative efforts, (4) Training and cross-training, (5) Using protocols for sharing confidential information, and (6) Using dependency drug courts. Although more rigorous research is needed on both individual-level and system-level substance abuse interventions for parents involved in the child welfare system, the integration of individual-level interventions and system-level approaches is a potentially useful practice approach with this vulnerable population.

  10. Methodology of clinical trials aimed at assessing interventions for cutaneous leishmaniasis.

    Directory of Open Access Journals (Sweden)

    Piero Olliaro

    Full Text Available The current evidence-base for recommendations on the treatment of cutaneous leishmaniasis (CL is generally weak. Systematic reviews have pointed to a general lack of standardization of methods for the conduct and analysis of clinical trials of CL, compounded with poor overall quality of several trials. For CL, there is a specific need for methodologies which can be applied generally, while allowing the flexibility needed to cover the diverse forms of the disease. This paper intends to provide clinical investigators with guidance for the design, conduct, analysis and report of clinical trials of treatments for CL, including the definition of measurable, reproducible and clinically-meaningful outcomes. Having unified criteria will help strengthen evidence, optimize investments, and enhance the capacity for high-quality trials. The limited resources available for CL have to be concentrated in clinical studies of excellence that meet international quality standards.

  12. Growth in late infancy among HIV-exposed children in urban Haiti is associated with participation in a clinic-based infant feeding support intervention. (United States)

    Heidkamp, Rebecca A; Stoltzfus, Rebecca J; Fitzgerald, Daniel W; Pape, Jean W


    The integration of nutrition support for infants of HIV-infected mothers is a recognized need; however, the evidence for effective programmatic solutions is weak. The objective of our study was to implement and evaluate a new infant feeding support intervention for HIV-exposed, uninfected, non-breast-fed infants 6-12 mo of age attending the Groupe Haïtien d'Etude du Sarcome de Kaposi et des Infections Opportunistes (GHESKIO) pediatric clinic in Port-au-Prince, Haiti. The 24-wk intervention included a lipid-based nutrient supplement, education, promotion of existing clinical services, and social support. We compared growth outcomes among intervention participants (n = 73) at start (wk 0) and end (wk 24) of intervention to a historical control group of HIV-exposed infants seen at the GHESKIO in the year prior to the intervention who would have met the intervention entrance criteria (n = 294). The intervention and historical control groups did not differ significantly at age 6 mo (wk 0). At age 12 mo (wk 24), the intervention group had a lower prevalence of underweight and stunting than the historical control group (weight-for-age Z-score children from 6 to 12 mo of age. This is a promising intervention model that can be adapted and scaled-up to other HIV care contexts.

  13. Proprioception: where are we now? A commentary on clinical assessment, changes across the life course, functional implications and future interventions. (United States)

    Suetterlin, Karen Joan; Sayer, Avan Aihie


    Proprioception, the sense of where one is in space, is essential for effective interaction with the environment. A lack of or reduction in proprioceptive acuity has been directly correlated with falls and with reduced functional independence in older people. Proprioceptive losses have also been shown to negatively correlate with functional recovery post stroke and play a significant role in other conditions such as Parkinson's disease. However, despite its central importance to many geriatric syndromes, the clinical assessment of proprioception has remained remarkably static. We look at approaches to the clinical assessment of proprioception, changes in proprioception across the life course, functional implications of proprioception in health and disease and the potential for targeted interventions in the future such as joint taping, and proprioception-specific rehabilitation and footwear.

    BACKGROUND Excessive use of alcohol is associated with poor sexual health, but the clinical effectiveness and cost-effectiveness of brief alcohol intervention in this setting has not been investigated. OBJECTIVE To examine the effects and cost-effectiveness of brief intervention for excessive alcohol consumption among people who attend sexual health clinics. DESIGN A two-arm, parallel-group, single-blind, pragmatic, randomised controlled trial. Participants were randomised via an independent and remote telephone randomisation service using permuted blocks, stratified by clinic. SETTING Study participants were recruited from three sexual health clinics in central and west London. PARTICIPANTS For inclusion, potential participants had to be aged ≥ 19 years, drink excessive alcohol according to the Modified-Single Alcohol Screening Question, and be willing to provide written informed consent. We excluded those who were unable to communicate in English sufficiently well to complete the baseline assessment and those who could not provide contact details for the follow-up assessment. INTERVENTIONS Brief advice was delivered by the treating clinician and comprised feedback on the possible health consequences of excessive drinking, a discussion of whether the participant's clinic attendance was linked to current alcohol use, written information on alcohol and health and an offer of an appointment with an alcohol health worker (AHW). Appointments with AHWs took place either in person or by telephone, lasted up to 30 minutes, and used the 'FRAMES' (Feedback about the adverse effects of alcohol, an emphasis on personal Responsibility for changing drinking behaviour, Advice about alcohol consumption, a Menu of options for further help and advice, an Empathic stance towards the patient and an emphasis on Self-efficacy) approach. Those in the control arm of the trial were offered a copy of a leaflet providing general information on health and lifestyle. MAIN OUTCOME MEASURES

  16. Impact of SYNTAX score on 1-year clinical outcomes in patients undergoing percutaneous coronary intervention for unprotected left main coronary artery. (United States)

    Nozue, Tsuyoshi; Kamijima, Ryo; Iwaki, Taku; Michishita, Ichiro


    SYNTAX score is an angiographic scoring system that was developed to quantify the number, complexity, and location of lesions in patients undergoing coronary revascularization. Up to now, the impact of SYNTAX score on clinical outcomes in patients undergoing percutaneous coronary intervention (PCI) for unprotected left main coronary artery (LMCA) lesions has not been fully examined. Therefore, we evaluate the usefulness of the SYNTAX score and identify the cutoff value of this score to predict 1-year clinical outcomes in patients undergoing PCI for unprotected LMCA lesions. This was a single-center retrospective study that included 49 consecutive patients undergoing elective PCI for unprotected LMCA lesions. We calculated the SYNTAX score and examined the correlations between this score and 1-year clinical outcomes. Major adverse cardiac events (MACE) occurred in 12 patients (24%): target lesion revascularization in 9 patients (18%), myocardial infarction in 2 (4%), and cardiac death in 1 (2%). The frequency of MACE was significantly higher in the intermediate (47%) or high score group (50%) than in the low score group (4%). Furthermore, the SYNTAX score was significantly higher in the MACE group than in the non-MACE group (31 vs. 22, p = 0.008). Receiver-operating characteristic curve showed that the SYNTAX score exhibited 83% sensitivity and 76% specificity for predicting the development of MACE at a cutoff value 26. These results demonstrate that the SYNTAX score could be a useful tool to predict 1-year clinical outcomes in patients undergoing elective PCI for unprotected LMCA lesions.

  17. Quantified self and human movement: a review on the clinical impact of wearable sensing and feedback for gait analysis and intervention. (United States)

    Shull, Pete B; Jirattigalachote, Wisit; Hunt, Michael A; Cutkosky, Mark R; Delp, Scott L


    The proliferation of miniaturized electronics has fueled a shift toward wearable sensors and feedback devices for the mass population. Quantified self and other similar movements involving wearable systems have gained recent interest. However, it is unclear what the clinical impact of these enabling technologies is on human gait. The purpose of this review is to assess clinical applications of wearable sensing and feedback for human gait and to identify areas of future research. Four electronic databases were searched to find articles employing wearable sensing or feedback for movements of the foot, ankle, shank, thigh, hip, pelvis, and trunk during gait. We retrieved 76 articles that met the inclusion criteria and identified four common clinical applications: (1) identifying movement disorders, (2) assessing surgical outcomes, (3) improving walking stability, and (4) reducing joint loading. Characteristics of knee and trunk motion were the most frequent gait parameters for both wearable sensing and wearable feedback. Most articles performed testing on healthy subjects, and the most prevalent patient populations were osteoarthritis, vestibular loss, Parkinson's disease, and post-stroke hemiplegia. The most widely used wearable sensors were inertial measurement units (accelerometer and gyroscope packaged together) and goniometers. Haptic (touch) and auditory were the most common feedback sensations. This review highlights the current state of the literature and demonstrates substantial potential clinical benefits of wearable sensing and feedback. Future research should focus on wearable sensing and feedback in patient populations, in natural human environments outside the laboratory such as at home or work, and on continuous, long-term monitoring and intervention.

  18. A clinically integrated post-graduate training programme in evidence-based medicine versus 'no intervention' for improving disability evaluations: a cluster randomised clinical trial.

    Directory of Open Access Journals (Sweden)

    Rob Kok

    Full Text Available BACKGROUND: Although several studies have shown that teaching EBM is effective in improving knowledge, at present, there is no convincing evidence that teaching EBM also changes professional behaviour in practice. Therefore, the primary aim of this study was to evaluate the effectiveness of a clinically integrated post-graduate training programme in EBM on evidence-based disability evaluation. METHODS AND FINDINGS: In a cluster randomised controlled trial, fifty-four case-based learning groups consisting of 132 physicians and 1680 patients were randomly assigned to the intervention or control groups. A clinically integrated, post-graduate, 5-day training programme in evidence-based medicine, consisting of (home assignments, peer teaching, interactive training in searching databases, lectures and brainstorming sessions was provided to the intervention group. The control group received no training. The primary outcome was evidence-based disability evaluation, as indicated by the frequency in use of evidence of sufficient quality in disability evaluation reports. There are no general EBM behaviour outcome measures available. Therefore, we followed general guidelines for constructing performance indicators and defined an a priori cut-off for determination of sufficient quality as recommended for evaluating EB training. Physicians trained in EBM performed more evidence-based disability evaluations compared to physicians in the control group (difference in absolute proportion 9.7%, 95% CI 3.5 to 15.9. The primary outcome differences between groups remained significant after both cluster-adjusted analysis and additional sensitivity analyses accounting for subjects lost to follow-up. CONCLUSIONS: A EBM programme successfully improved the use of evidence in a non-hospital based medical specialty. Our findings support the general recommendations to use multiple educational methods to change physician behaviour. In addition, it appeared important that the

  19. A common type system for clinical natural language processing

    Directory of Open Access Journals (Sweden)

    Wu Stephen T


    Full Text Available Abstract Background One challenge in reusing clinical data stored in electronic medical records is that these data are heterogenous. Clinical Natural Language Processing (NLP plays an important role in transforming information in clinical text to a standard representation that is comparable and interoperable. Information may be processed and shared when a type system specifies the allowable data structures. Therefore, we aim to define a common type system for clinical NLP that enables interoperability between structured and unstructured data generated in different clinical settings. Results We describe a common type system for clinical NLP that has an end target of deep semantics based on Clinical Element Models (CEMs, thus interoperating with structured data and accommodating diverse NLP approaches. The type system has been implemented in UIMA (Unstructured Information Management Architecture and is fully functional in a popular open-source clinical NLP system, cTAKES (clinical Text Analysis and Knowledge Extraction System versions 2.0 and later. Conclusions We have created a type system that targets deep semantics, thereby allowing for NLP systems to encapsulate knowledge from text and share it alongside heterogenous clinical data sources. Rather than surface semantics that are typically the end product of NLP algorithms, CEM-based semantics explicitly build in deep clinical semantics as the point of interoperability with more structured data types.

    A patient registration system is mandatory for establishing the scientific credibility of the multi-center clinical trials. The Japan Interventional Radiology in Oncology Study Group (JIVROSG) was organized in 2002 to establish evidence supporting the procedures used in interventional radiology. The Internet Data and Information Center for Medical Research (INDICE), provided by the University Hospital Medical Information Network(UMIN), has been utilized for patient registration in the clinical trials of JIVROSG. In this study, the safety and efficacy of UMIN-INDICE were evaluated. From 2002 to 2010, 18 clinical trials, including one international trial, were conducted. A total of 736 patients were enrolled from 51 institutions. No significant trouble was encountered during this period. A questionnaire survey demonstrated that 90% of participating researchers could use this system without difficulties. UMIN-INDICE may contribute to promoting clinical trials as an infrastructure of multicenter studies.

  1. Data for improvement and clinical excellence: protocol for an audit with feedback intervention in long-term care

    Directory of Open Access Journals (Sweden)

    Schalm Corinne


    Full Text Available Abstract Background There is considerable evidence about the effectiveness of audit coupled with feedback, although few audit with feedback interventions have been conducted in long-term care (LTC settings to date. In general, the effects have been found to be modest at best, although in settings where there has been little history of audit and feedback, the effects may be greater, at least initially. The primary purpose of the Data for Improvement and Clinical Excellence (DICE Long-Term Care project is to assess the effects of an audit with feedback intervention delivered monthly over 13 months in four LTC facilities. The research questions we addressed are: 1. What effects do feedback reports have on processes and outcomes over time? 2. How do different provider groups in LTC and home care respond to feedback reports based on data targeted at improving quality of care? Methods/design The research team conducting this study comprises researchers and decision makers in continuing care in the province of Alberta, Canada. The intervention consists of monthly feedback reports in nine LTC units in four facilities in Edmonton, Alberta. Data for the feedback reports comes from the Resident Assessment Instrument Minimum Data Set (RAI version 2.0, a standardized instrument mandated for use in LTC facilities throughout Alberta. Feedback reports consist of one page, front and back, presenting both graphic and textual information. Reports are delivered to all staff working in the four LTC facilities. The primary evaluation uses a controlled interrupted time series design both adjusted and unadjusted for covariates. The concurrent process evaluation uses observation and self-report to assess uptake of the feedback reports. Following the project phase described in this protocol, a similar intervention will be conducted in home care settings in Alberta. Depending on project findings, if they are judged useful by decision makers participating in this research

  2. The empathic brain and its dysfunction in psychiatric populations: implications for intervention across different clinical conditions

    Directory of Open Access Journals (Sweden)

    Moriguchi Yoshiya


    Full Text Available Abstract Empathy is a concept central to psychiatry, psychotherapy and clinical psychology. The construct of empathy involves not only the affective experience of the other person's actual or inferred emotional state but also some minimal recognition and understanding of another's emotional state. It is proposed, in the light of multiple levels of analysis including social psychology, cognitive neuroscience and clinical neuropsychology, a model of empathy that involves both bottom-up and top-down information processing underpinned by parallel and distributed computational mechanisms. The predictive validity of this model is explored with reference to clinical conditions. As many psychiatric conditions are associated with deficits or even lack of empathy, we discuss a limited number of these disorders including psychopathy/antisocial personality disorders, borderline and narcissistic personality disorders, autistic spectrum disorders, and alexithymia. We argue that future clinical investigations of empathy disorders can only be informative if behavioral, dispositional and biological factors are combined.

  3. Completeness of reporting in abstracts from clinical trials of pre-harvest interventions against foodborne pathogens. (United States)

    Snedeker, Kate G; Canning, Paisley; Totton, Sarah C; Sargeant, Jan M


    Abstracts are the most commonly read part of a journal article, and play an important role as summaries of the articles, and search and screening tools. However, research on abstracts in human biomedicine has shown that abstracts often do not report key methodological features and results. Little research has been done to examine reporting of such features in abstracts from papers detailing pre-harvest food safety trials. Thus, the objective of this study was to assess the quality of reporting of key factors in abstracts detailing trials of pre-harvest food safety interventions. A systematic search algorithm was used to identify all in vivo trials of pre-harvest interventions against foodborne pathogens in PubMed and CAB Direct published from 1999 to October 2009. References were screened for relevance, and 150 were randomly chosen for inclusion in the study. A checklist based on the CONSORT abstract extension and the REFLECT Statement was used to assess the reporting of methodological features and results. All screening and assessment was performed by two independent reviewers with disagreements resolved by consensus. The systematic search returned 3554 unique citations; 356 were found to be relevant and 150 were randomly selected for inclusion. The abstracts were from 51 different journals, and 13 out of 150 were structured. Of the 124 abstracts that reported whether the trial design was deliberate disease challenge or natural exposure, 113 were deliberate challenge and 11 natural exposure. 103 abstracts detailed studies involving poultry, 20 cattle and 15 swine. Most abstracts reported the production stage of the animals (135/150), a hypothesis or objective (123/150), and results for all treatment groups (136/150). However, few abstracts reported on how animals were grouped in housing (25/150), the location of the study (5/150), the primary outcome (2/126), level of treatment allocation (15/150), sample size (63/150) or whether study units were lost to follow up

  5. Recent Clinical Results of Endoscopic Bariatric Therapies as an Obesity Intervention (United States)

    Bazerbachi, Fateh; Vargas Valls, Eric J.; Abu Dayyeh, Barham K.


    Despite advances in lifestyle interventions, anti-obesity medications, and metabolic surgery, the issue of health burden due to obesity continues to evolve. Interest in endoscopic bariatric techniques has increased over the years, as they have been shown to be efficacious, reversible, relatively safe, and cost effective. Further, these techniques offer a therapeutic window for some patients who may otherwise be unable to undergo bariatric surgery. This article aims to review the literature on the safety and efficacy of currently offered endoscopic bariatric techniques, as well as those that are in the pipeline of end-development and regulatory approval.

    Purpose: Three-dimensional (3-D) reconstruction of the coronary arteries during a cardiac catheter-based intervention can be performed from a C-arm based rotational x-ray angiography sequence. It can support the diagnosis of coronary artery disease, treatment planning, and intervention guidance. 3-D reconstruction also enables quantitative vessel analysis, including vessel dynamics from a time-series of reconstructions. Methods: The strong angular undersampling and motion effects present in gated cardiac reconstruction necessitate the development of special reconstruction methods. This contribution presents a fully automatic method for creating high-quality coronary artery reconstructions. It employs a sparseness-prior based iterative reconstruction technique in combination with projection-based motion compensation. Results: The method is tested on a dynamic software phantom, assessing reconstruction accuracy with respect to vessel radii and attenuation coefficients. Reconstructions from clinical cases are presented, displaying high contrast, sharpness, and level of detail. Conclusions: The presented method enables high-quality 3-D coronary artery imaging on an interventional C-arm system.

  7. The development of a systemic school-based intervention: Marte Meo and coordination meetings. (United States)

    Axberg, Ulf; Hansson, Kjell; Broberg, Anders G; Wirtberg, Ingegerd


    Antisocial behavior is often persistent, and in addition to causing suffering to children and their families, it also poses considerable costs for society. Children who display externalizing behavior in their early years run a high risk of having severe problems later in life. There is a need for treatment methods that may be used in various settings because these children constitute a group that is hard to reach with conventional treatment methods. In addition, the dropout rate from ordinary treatment is often high. In the present study, a systemic school-based model for early detection and intervention among 4-12-year-old children who displayed externalizing behavior problems was developed and examined in a nonrandomized study in the county of Skaraborg in Sweden. The intervention was collaborative and included a combination of the Marte Meo model and coordination meetings based on systemic theory and practice. Treatment effects in the group who had received the intervention were compared with a group who had received treatment as usual in their ordinary school setting. Assessments were carried out before, and 2 years after, the intervention. For the intervention group (N = 33), there was a significant decrease in the children's reported symptoms in school and in the home. No decrease in externalizing behavior was found in the comparison group (N = 16). There were no dropouts in the intervention group after the intervention had begun. The results are promising; the study demonstrates that it is possible to work effectively with many children who display externalizing behavior problems in a nonclinical setting.

  8. Guidance from an NIH Workshop on Designing, Implementing, and Reporting Clinical Studies of Soy Interventions1–4 (United States)

    Klein, Marguerite A.; Nahin, Richard L.; Messina, Mark J.; Rader, Jeanne I.; Thompson, Lilian U.; Badger, Thomas M.; Dwyer, Johanna T.; Kim, Young S.; Pontzer, Carol H.; Starke-Reed, Pamela E.; Weaver, Connie M.


    The NIH sponsored a scientific workshop, “Soy Protein/Isoflavone Research: Challenges in Designing and Evaluating Intervention Studies,” July 28–29, 2009. The workshop goal was to provide guidance for the next generation of soy protein/isoflavone human research. Session topics included population exposure to soy; the variability of the human response to soy; product composition; methods, tools, and resources available to estimate exposure and protocol adherence; and analytical methods to assess soy in foods and supplements and analytes in biologic fluids and other tissues. The intent of the workshop was to address the quality of soy studies, not the efficacy or safety of soy. Prior NIH workshops and an evidence-based review questioned the quality of data from human soy studies. If clinical studies are pursued, investigators need to ensure that the experimental designs are optimal and the studies properly executed. The workshop participants identified methodological issues that may confound study results and interpretation. Scientifically sound and useful options for dealing with these issues were discussed. The resulting guidance is presented in this document with a brief rationale. The guidance is specific to soy clinical research and does not address nonsoy-related factors that should also be considered in designing and reporting clinical studies. This guidance may be used by investigators, journal editors, study sponsors, and protocol reviewers for a variety of purposes, including designing and implementing trials, reporting results, and interpreting published epidemiological and clinical studies.

  9. Building the rationale and structure for a complex physical therapy intervention within the context of a clinical trial: a multimodal individualized treatment for patients with hip osteoarthritis. (United States)

    Bennell, Kim L; Egerton, Thorlene; Pua, Yong-Hao; Abbott, J Haxby; Sims, Kevin; Buchbinder, Rachelle


    Evaluating the efficacy of complex interventions such as multimodal, impairment-based physical therapy treatments in randomized controlled trials is essential to inform practice and compare relative benefits of available treatment options. Studies of physical therapy interventions using highly standardized intervention protocols, although methodologically rigorous, do not necessarily reflect "real-world" clinical practice, and in many cases results have been disappointing. Development of a complex intervention that includes multiple treatment modalities and individualized treatment technique selection requires a systematic approach to designing all aspects of the intervention based on theory, evidence, and practical constraints. This perspective article outlines the development of the rationale and structure of a multimodal physical therapy program for painful hip osteoarthritis to be assessed in a clinical trial. The resulting intervention protocol comprises a semi-structured program of exercises and manual therapy, advice, physical activity, and optional prescription of a gait aid that is standardized, yet can be individualized according to physical assessment and radiographic findings. The program is evidence based and reflects contemporary physical therapist practice, while also being reproducible and reportable. This perspective article aims to encourage physical therapy researchers involved in evaluation of complex interventions to better document their own intervention development, as well as the outcomes, thus generating a body of knowledge about the development processes and protocols that is generalizable to the real-world complexity of providing physical therapy to individual patients.

  10. [The initial trial of the clinical use of FK-1 glue in surgical interventions]. (United States)

    Abzhueva, O V; Rusanov, V M; Zhidkov, I L


    The article presents results of a comparative clinical trial of the preparation "fibrinous glue" (FK-1) and "Beriplast" in operations on the lungs for hermetization of the wound and the lung as well as in reconstructive plastic gynecological operations. Intraoperative hermetization in operations on the lungs was obtained in 67% of the cases when using "FK-1" and in 64% with "Beriplast". In all the cases the lung was spread during 12 hours after operation. The visual intraoperative assessment of using "FK-1" and control laparoscopy on the 4th-5th days after operation showed its good effect in gynecological procedures.

    Znoj, Hans-Jörg; Messerli-Burgy, Nadine; Tschopp, Simone; Weber, Rainer; Christen, Lisanne; Christen, Stephan; Grawe, Klaus


    The aim of this exploratory study was to examine the possible mechanisms of behavioral change in a cognitive-behavioral intervention supporting medication adherence in HIV-infected persons. A total of 60 persons currently under medical treatment were randomized to psychotherapy or usual care and were compared with a sociodemographically matched group of general psychotherapy clients. Outcome measures included therapy adherence using medication event-monitoring system psychotherapeutic processes and changes of experience and behavior. The general psychotherapy group was initially more distressed than HIV psychotherapy patients and reached higher levels of psychotherapeutic effect. In the HIV psychotherapy patients, a significant effect was found for maintaining adherence to medical treatment (Weber et al., 2004). These findings show that psychotherapy is a beneficial intervention for HIV-infected persons, and therapeutic alliance and activation of resources do not differ from a general psychotherapy treatment. Differential effects were detected for specific process variables, namely problem actuation.

  17. Exploring links between genotypes, phenotypes, and clinical predictors of response to early intensive behavioural intervention in Autism Spectrum Disorder

    Directory of Open Access Journals (Sweden)

    Valsamma eEapen


    Full Text Available Autism Spectrum Disorder (ASD is amongst the most familial of psychiatric disorders. Twin and family studies have demonstrated a monozygotic concordance rate of 70–90%, dizygotic concordance of around 10% and more than a 20-fold increase in risk for first-degree relatives. Despite major advances in the genetics of autism, the relationship between different aspects of the behavioural and cognitive phenotype and their underlying genetic liability is still unclear. This is complicated by the heterogeneity of autism, which exists at both genetic and phenotypic levels. Given this heterogeneity, one method to find homogeneous entities and link these with specific genotypes would be to pursue endophenotypes. Evidence from neuroimaging, eye tracking and electrophysiology studies supports the hypothesis that, building on genetic vulnerability, ASD emerges from a developmental cascade in which a deficit in attention to social stimuli leads to impaired interactions with primary caregivers. This results in abnormal development of the neurocircuitry responsible for social cognition, which in turn adversely affects later behavioural and functional domains dependent on these early processes, such as language development. Such a model begets a heterogeneous clinical phenotype, and is also supported by studies demonstrating better clinical outcomes with earlier treatment. Treatment response following intensive early behavioural intervention in ASD is also distinctly variable; however, relatively little is known about specific elements of the clinical phenotype that may predict response to current behavioural treatments. This paper overviews the literature regarding genotypes, phenotypes and predictors of response to behavioural intervention in ASD and presents suggestions for future research to explore linkages between these that would enable better identification of, and increased treatment efficacy for, ASD.

  18. Evaluation of different systems for clinical quantification of varicose veins. (United States)

    Cornu-Thénard, A; De Vincenzi, I; Maraval, M


    One hundred twenty-five lower limbs with varicose veins were studied clinically, essentially by palpation. Two specialists in venous pathology scored the severity of the varicose veins from 0 to 20. Comparison between the different clinical parameters and the scores of the specialists showed that two systems of clinical quantification gave good results and were easy to use. One system is the maximum diameter of the largest varicose vein; the other system is the sum of maximum diameters over 7 sections (3 for thigh, 3 for leg, 1 for foot). This latter system gives a more precise evaluation of the clinical severity of the varicose veins.

  20. Data for improvement and clinical excellence: protocol for an audit with feedback intervention in home care and supportive living

    Directory of Open Access Journals (Sweden)

    Fraser Kimberly D


    Full Text Available Abstract Background Although considerable evidence exists about the effectiveness of audit coupled with feedback, very few audit-with-feedback interventions have been done in either home care or supportive living settings to date. With little history of audit and feedback in home care or supportive living there is potential for greater effects, at least initially. This study extends the work of an earlier study designed to assess the effects of an audit-with-feedback intervention. It will be delivered quarterly over a one-year period in seven home care offices and 11 supportive living sites. The research questions are the same as in the first study but in a different environment. They are as follows: 1. What effects do feedback reports have on processes and outcomes over time? 2. How do different provider groups in home care and supportive living sites respond to feedback reports based on quality indicator data? Methods The research team conducting this study includes researchers and decision makers in continuing care in the province of Alberta, Canada. The intervention consists of quarterly feedback reports in 19 home care offices and supportive living sites across Alberta. Data for the feedback reports are based on the Resident Assessment Instrument Home Care tool, a standardized instrument mandated for use in home care and supportive living environments throughout Alberta. The feedback reports consist of one page, printed front and back, presenting both graphic and textual information. Reports are delivered to all employees working in each site. The primary evaluation uses a controlled interrupted time-series design, both adjusted and unadjusted for covariates. The concurrent process evaluation includes observation, focus groups, and self-reports to assess uptake of the feedback reports. The project described in this protocol follows a similar intervention conducted in our previous study, Data for Improvement and Clinical Excellence

  3. Family perceptions of early hearing, detection, and intervention systems: listening to and learning from families. (United States)

    DesGeorges, Janet


    As universal newborn hearing systems (screening, diagnosis, intervention) are being established around the world, the success of children who are identified to be deaf and hard of hearing is critically impacted by parent's reactions, acceptance, and advocacy for their child. It is imperative for professionals who are creating systems for Early Hearing, Detection, and Intervention to understand and learn from families' experiences in order to improve this process. This manuscript will identify the areas in which parents have spoken out about the professionals they have encountered through the system: what parents wish for in a healthy, productive relationship with professionals; and how parents can play a part in advocating for a system in which families needs are met so that infants identified to be deaf or hard of hearing can reach their full potential.

  4. A randomized clinical trial of a peri-operative behavioral intervention to improve physical activity adherence and functional outcomes following total knee replacement

    Directory of Open Access Journals (Sweden)

    Zheng Hua


    Full Text Available Abstract Background Total knee replacement (TKR is a common and effective surgical procedure to relieve advanced knee arthritis that persists despite comprehensive medical treatment. Although TKR has excellent technical outcomes, significant variation in patient-reported functional improvement post-TKR exists. Evidence suggests that consistent post-TKR exercise and physical activity is associated with functional gain, and that this relationship is influenced by emotional health. The increasing use of TKR in the aging US population makes it critical to find strategies that maximize functional outcomes. Methods/Design This randomized clinical trial (RCT will test the efficacy of a theory-based telephone-delivered Patient Self-Management Support intervention that seeks to enhance adherence to independent exercise and activity among post- TKR patients. The intervention consists of 12 sessions, which begin prior to surgery and continue for approximately 9 weeks post-TKR. The intervention condition will be compared to a usual care control condition using a randomized design and a probabilistic sample of men and women. Assessments are conducted at baseline, eight weeks, and six- and twelve- months. The project is being conducted at a large healthcare system in Massachusetts. The study was designed to provide greater than 80% power for detecting a difference of 4 points in physical function (SF36/Physical Component Score between conditions (standard deviation of 10 at six months with secondary outcomes collected at one year, assuming a loss to follow up rate of no more than 15%. Discussion As TKR use expands, it is important to develop methods to identify patients at risk for sub-optimal functional outcome and to effectively intervene with the goal of optimizing functional outcomes. If shown efficacious, this peri-TKR intervention has the potential to change the paradigm for successful post-TKR care. We hypothesize that Patient Self-Management Support

  5. Experimental gingivitis induces systemic inflammatory markers in young healthy individuals: a single-subject interventional study.

    Directory of Open Access Journals (Sweden)

    Jörg Eberhard

    Full Text Available OBJECTIVES: We here investigated whether experimental gingivitis enhances systemic markers of inflammation which are also known as surrogate markers of atherosclerotic plaque development. BACKGROUND: Gingivitis is a low-level oral infection induced by bacterial deposits with a high prevalence within Western populations. A potential link between the more severe oral disease periodontitis and cardiovascular disease has already been shown. METHODS: 37 non-smoking young volunteers with no inflammatory disease or any cardiovascular risk factors participated in this single-subject interventional study with an intra-individual control. Intentionally experimental oral inflammation was induced by the interruption of oral hygiene for 21 days, followed by a 21-days resolving phase after reinitiation of oral hygiene. Primary outcome measures at baseline, day 21 and 42 were concentrations of hsCRP, IL-6, and MCP-1, as well as adhesion capacity and oxLDL uptake of isolated blood monocytes. RESULTS: The partial cessation of oral hygiene procedures was followed by the significant increase of gingival bleeding (34.0%, P<0.0001. This local inflammation was associated with a systemic increase in hsCRP (0.24 mg/L, P = 0.038, IL-6 (12.52 ng/L, P = 0.0002 and MCP-1 (9.10 ng/l, P = 0.124 in peripheral blood samples between baseline and day 21, which decreased at day 42. Monocytes showed an enhanced adherence to endothelial cells and increased foam cell formation after oxLDL uptake (P<0.050 at day 21 of gingivitis. CONCLUSIONS: Bacterial-induced gingival low-level inflammation induced a systemic increase in inflammatory markers. Dental hygiene almost completely reversed this experimental inflammatory process, suggesting that appropriate dental prophylaxis may also limit systemic markers of inflammation in subjects with natural gingivitis.

  6. Perinatal complications associated with autism--a case control study in a neurodevelopment and early intervention clinic. (United States)

    Nath, Saswati; Roy, Rita; Mukherjee, Suchandra


    Early and intensive intervention can have a profound impact on the quality of life for children at risk for autism. Hence a high degree of suspicion towards babies exposed to known risk factors is warranted. Previous studies have shown that different perinatal factors like antepartum bleeding, postmaturity, birth asphyxia, meconium aspiration syndrome, anaemia in early infancy and exposure to toxins of various origins makes an infant susceptible to development of autism; attention deficit hyperactivity disorder (ADHD) and other neurodevelopmental disorders in later life.This study aims to find out the association of perinatal risk factors in relation to development of autism spectrum disorders. All babies who are at least three years of age, attending the neurodevelopment and early intervention clinic at SSKM Hospital at Kolkata taken as cases. Age matched controls were taken from general paediatric OPD of the same hospital. After history taking, physical and neurological examination, developmental maturity was assessed by the Denver Developmental Screening Test (DDST) and Vineland Social Maturity Scale (VSMS). A semi-structured parent's questionnaire and the modified checklist for autism in toddlers (M-CHAT) was used to screen for autism. Diagnosis was confirmed by DSM-IV-TR (Diagnostic and Statistical Manual of Mental Disorders - Fourth Edition, Text Revision) criteria. Significant correlation was found between presence of antepartum haemorrhage, pregnancy induced hypertension, preterm delivery and autism in the baby. Perinatal complications are important risk factor for autism. Knowing the risk factors will help clinicians to be aware of the avoidable complications, and to undertake either preventive steps or intense intervention to reduce the degree of disability.

  7. Can the theoretical domains framework account for the implementation of clinical quality interventions?


    Lipworth, Wendy; Taylor, Natalie; Braithwaite, Jeffrey


    Background The health care quality improvement movement is a complex enterprise. Implementing clinical quality initiatives requires attitude and behaviour change on the part of clinicians, but this has proven to be difficult. In an attempt to solve this kind of behavioural challenge, the theoretical domains framework (TDF) has been developed. The TDF consists of 14 domains from psychological and organisational theory said to influence behaviour change. No systematic research has been conducte...

  8. An assembly-type master-slave catheter and guidewire driving system for vascular intervention. (United States)

    Cha, Hyo-Jeong; Yi, Byung-Ju; Won, Jong Yun


    Current vascular intervention inevitably exposes a large amount of X-ray to both an operator and a patient during the procedure. The purpose of this study is to propose a new catheter driving system which assists the operator in aspects of less X-ray exposure and convenient user interface. For this, an assembly-type 4-degree-of-freedom master-slave system was designed and tested to verify the efficiency. First, current vascular intervention procedures are analyzed to develop a new robotic procedure that enables us to use conventional vascular intervention devices such as catheter and guidewire which are commercially available in the market. Some parts of the slave robot which contact the devices were designed to be easily assembled and dissembled from the main body of the slave robot for sterilization. A master robot is compactly designed to conduct insertion and rotational motion and is able to switch from the guidewire driving mode to the catheter driving mode or vice versa. A phantom resembling the human arteries was developed, and the master-slave robotic system is tested using the phantom. The contact force of the guidewire tip according to the shape of the arteries is measured and reflected to the user through the master robot during the phantom experiment. This system can drastically reduce radiation exposure by replacing human effort by a robotic system for high radiation exposure procedures. Also, benefits of the proposed robot system are low cost by employing currently available devices and easy human interface.

  11. What Clinical Interventions Have Been Implemented to Prevent or Reduce Postpartum Hypertension Readmissions? A Clin-IQ

    Directory of Open Access Journals (Sweden)

    Sara O'Meara


    Full Text Available A literature review was conducted to determine what clinical interventions have been studied and implemented to prevent and/or reduce postpartum hypertension readmissions. Appropriate verbal and printed educational materials should be given to the patient prior to discharge with use of the “teach back” method. Patients and health care providers within the multidisciplinary team should be educated on the warning signs and symptoms of worsening hypertensive disease and when to appropriately involve the obstetrician. The use of text messaging may be useful in preventing hospital readmissions by increasing patient follow-up and compliance and appropriately managing patients in the postpartum period. Treating postpartum patients with furosemide may decrease blood pressure and prevent postpartum hypertension and the need for antihypertensive therapy.

  12. Multiparameter Stochastic Dynamics of Ecological Tourism System with Continuous Visitor Education Interventions

    Dongping Wei


    Full Text Available Management of ecological tourism in protected areas faces many challenges, with visitation-related resource degradations and cultural impacts being two of them. To address those issues, several strategies including regulations, site managements, and visitor education programs have been commonly used in China and other countries. This paper presents a multiparameter stochastic differential equation model of an Ecological Tourism System to study how the populations of stakeholders vary in a finite time. The solution of Ordinary Differential Equation of Ecological Tourism System reveals that the system collapses when there is a lack of visitor educational intervention. Hence, the Stochastic Dynamic of Ecological Tourism System is introduced to suppress the explosion of the system. But the simulation results of the Stochastic Dynamic of Ecological Tourism System show that the system is still unstable and chaos in some small time interval. The Multiparameters Stochastic Dynamics of Ecological Tourism System is proposed to improve the performance in this paper. The Multiparameters Stochastic Dynamics of Ecological Tourism System not only suppresses the explosion of the system in a finite time, but also keeps the populations of stakeholders in an acceptable level. In conclusion, the Ecological Tourism System develops steadily and sustainably when land managers employ effective visitor education intervention programs to deal with recreation impacts.

  13. Uptake of prevention of mother to child transmission interventions in Kenya: health systems are more influential than stigma

    Kinuthia John


    Full Text Available Abstract Background We set out to determine the relative roles of stigma versus health systems in non-uptake of prevention of mother to child transmission (PMTCT of HIV-1 interventions: we conducted cross-sectional assessment of all consenting mothers accompanying infants for six-week immunizations. Methods Between September 2008 and March 2009, mothers at six maternal and child health clinics in Kenya's Nairobi and Nyanza provinces were interviewed regarding PMTCT intervention uptake during recent pregnancy. Stigma was ascertained using a previously published standardized questionnaire and infant HIV-1 status determined by HIV-1 polymerase chain reaction. Results Among 2663 mothers, 2453 (92.1% reported antenatal HIV-1 testing. Untested mothers were more likely to have less than secondary education (85.2% vs. 74.9%, p = 0.001, be from Nyanza (47.1% vs. 32.2%, p Conclusions Antenatal HIV-1 testing and antiretroviral uptake was high (both more than 90% and infant HIV-1 infection risk was low, reflecting high PMTCT coverage. Investment in health systems to deliver HIV-1 testing and antiretrovirals can effectively prevent infant HIV-1 infection despite substantial HIV-1 stigma.

  14. The Stochastic Dynamics for Ecological Tourism System with Visitor Educational Intervention

    Directory of Open Access Journals (Sweden)

    Dongping Wei


    Full Text Available The ever-increasing visitation in parks and protected areas continues to present a considerable challenge for worldwide land managers with allowing recreational use while preserving natural conditions. In China, the fast expanding visitation in protected areas is quickly damaging the natural resources and precious culture without effective visitor education, while regulation and site management are also gaining very limited efficacy. We propose a differential equation to describe the ecological tourism system. Shown by the theoretical proof and numerical simulation, the ecological tourism system is unstable without any perturbed factors, especially visitor educational intervention, because the solution of the dynamic system explodes in a finite time given any initial value. Supposing that the intrinsic increasing rate of stakeholders in the systems stochastically perturbed by the visitor educational intervention, we discover that the stochastic dynamic model can effectively suppress the explosion of the solution. As such, we demonstrate that the tourism system can develop steadily and safely even under a large amount of visitors in public vacation, when employing continuous visitor education intervention programmes.

  16. A Clinical Trial of Translation of Evidence Based Interventions to Mobile Tablets and Illness Specific Internet Sites. (United States)

    Smith, Carol E; Piamjariyakul, Ubolrat; Werkowitch, Marilyn; Yadrich, Donna Macan; Thompson, Noreen; Hooper, Dedrick; Nelson, Eve-Lynn


    This article describes a method to translate an evidence based health care intervention to the mobile environment. This translation assisted patient participants to: avoid life threatening infections; monitor emotions and fatigue; keep involved in healthy activities. The mobile technology also decreased costs by reducing for example travel to visit health care providers. Testing of this translation method and its use by comparison groups of patients adds to the knowledge base for assessing technology for its impact on health outcome measures. The challenges and workflow of designing materials for the mobile format are described. Transitioning clinical trial verified interventions, previously provided in person to patients, onto tablet and internet platforms is an important process that must be evaluated. In this study, our evidence based guide's intravenous (IV) homeCare interventions (IVhomeCare) were delivered via Apple iPad mini™ tablet audiovisual instruction / discussion sessions and on a website. Each iPad audiovisual session (n = 41), included three to five families, a mental health specialist, and healthcare professionals. Patients and their family caregivers readily learned to use the wireless mobile tablets, and the IVhomeCare interventions, as described here, were successfully translated onto these mobile technology platforms. Using Likert scale responses on a questionnaire (1 = not helpful and 5 = very helpful) participants indicated that they gained problem solving skills for home care through iPad group discussion (M = 4.60, SD = 0.60). The firewall protected videoconferencing in real time with multiple healthcare professionals effectively allowed health history taking and visual inspection of the patient's IV insertion site for signs of infection. Supportive interactions with peer families on videoconferencing were documented during discussions. Discussion topics included low moods, fatigue, infection worry, how to maintain independence, and need

    Full Text Available OBJECTIVES: Russia faces a high burden of cardiovascular disease. Prevalence of all cardiovascular risk factors, especially hypertension, is high. Elevated blood pressure is generally poorly controlled and medication usage is suboptimal. With a disease-model simulation, we forecast how various treatment programs aimed at increasing blood pressure control would affect cardiovascular outcomes. In addition, we investigated what additional benefit adding lipid control and smoking cessation to blood pressure control would generate in terms of reduced cardiovascular events. Finally, we estimated the direct health care costs saved by treating fewer cardiovascular events. METHODS: The Archimedes Model, a detailed computer model of human physiology, disease progression, and health care delivery was adapted to the Russian setting. Intervention scenarios of achieving systolic blood pressure control rates (defined as systolic blood pressure <140 mmHg of 40% and 60% were simulated by modifying adherence rates of an antihypertensive medication combination and compared with current care (23.9% blood pressure control rate. Outcomes of major adverse cardiovascular events; cerebrovascular event (stroke, myocardial infarction, and cardiovascular death over a 10-year time horizon were reported. Direct health care costs of strokes and myocardial infarctions were derived from official Russian statistics and tariff lists. RESULTS: To achieve systolic blood pressure control rates of 40% and 60%, adherence rates to the antihypertensive treatment program were 29.4% and 65.9%. Cardiovascular death relative risk reductions were 13.2%, and 29.6%, respectively. For the current estimated 43,855,000-person Russian hypertensive population, each control-rate scenario resulted in an absolute reduction of 1.0 million and 2.4 million cardiovascular deaths, and a reduction of 1.2 million and 2.7 million stroke/myocardial infarction diagnoses, respectively. Averted direct costs from

  18. How Transdiagnostic Factors of Personality and Psychopathology Can Inform Clinical Assessment and Intervention. (United States)

    Rodriguez-Seijas, Craig; Eaton, Nicholas R; Krueger, Robert F


    Research suggests that many mental disorders-mood and anxiety, substance use, and personality psychopathology-are related through relatively few latent transdiagnostic factors. With regard to the comorbidity of personality disorders and common mental disorders, factor structures such as internalizing-externalizing have been replicated in numerous samples, across the life span, and around the globe. One critical feature of transdiagnostic factors is that they serve as a point of intersection between personality and psychopathology, making them particularly relevant phenomena for applied clinical work. Although numerous studies have supported the significance of transdiagnostic factors for research and classification purposes, there has been comparatively less articulation of how such factors might be of benefit to practicing assessment clinicians. Herein, we present an overview of transdiagnostic factor research findings, and we apply these findings to the clinical topics of assessment, diagnosis, and treatment. For clinicians as well as researchers, the use of transdiagnostic constructs presents positive implications for efforts to understand, characterize, and ameliorate psychopathology-including its manifestations as personality disorder-in a valid, effective, and efficient way.

  19. Human computer interaction issues in Clinical Trials Management Systems. (United States)

    Starren, Justin B; Payne, Philip R O; Kaufman, David R


    Clinical trials increasingly rely upon web-based Clinical Trials Management Systems (CTMS). As with clinical care systems, Human Computer Interaction (HCI) issues can greatly affect the usefulness of such systems. Evaluation of the user interface of one web-based CTMS revealed a number of potential human-computer interaction problems, in particular, increased workflow complexity associated with a web application delivery model and potential usability problems resulting from the use of ambiguous icons. Because these design features are shared by a large fraction of current CTMS, the implications extend beyond this individual system.

    Objectives To evaluate the efficacy and safety of clinical application of a novel type of vascular closure device named Boomerang closure wire system (BCWS). Methods BCWSs were used in 288 patients (BCWSs group) for hemostasis after transfernoral coronary angiography (CAG) or percutaneous coronary intervention (PCI). Device suc-cess rate, hemostasis success rate, manual compression time, recumbent time, minor peripheral complication rate, se-vere peripheral complication rate and hospital staying time after procedure were analyzed. Results were compared to those from 300 patients (control group) who received manual compression in our hospital during the same period. Results In BCWS group, device success rate was 97.2 %, hemostasis success rate was 95.1%. Manual compression time in CAG subgroup and PCI subgroup was 7.8 min and 11.2 min, respectively. Recumbent time was 136. 3 min in CAG subgroup, 284.6 min in PCI subgroup. Minor peripheral complication rate was 4.5 %, severe peripheral compli-cation rate was 2.4 %. Hospital-staying time after procedure in CAG group and PCI group was 1.8 d and 6.6 d, re-spectively. Compared to control group, manual compression time, recumbent time and hospital-staying time of BCWSs group had statistical significance; hemostasis success rate, minor peripheral complication rate and severe peripheral complication rate of BCWSs group bad no statistical difference. Conclusions BCWS provides satisfied haemostatic effect. Compared to routine manual compression, BCWS shortens manual compression time, recumbent time and hos-pital staying time.

    AIM To study the effect of sclerotic complex agents (SCA) on the gallbladder wall of hybrid rabbits, andits therapeutic effect in hepatic cysts.METHODS The SCA containing tetracycline and dexamethasone was injected into the gallbladder of rabbitsto compare its action with those of normal saline and absolute ethylalcohol on the gallbladder wall. Thetherapeutic effects of SCA and absolute ethylalcohol on hepatic cysts were observed.RESULTS Abnormal changes were not found in the tissue cells of gallbladder in normal saline group. Butin absolute ethylalcohol group, a large amount of oozing fluid and blood appeared, the absorption processwas slow, and the fibrous tissue proliferated scarcely. In SCA group, there was less oozing fluid, no blood inthe gallbladder, and the absorption was active and the fibrous tissues grow obviously. In clinical practice,SCA possesses much advantage in the treatment of hepatic cysts, by which the cysts closed promptly, theexudation reduced from early stimulation, and no relapse occurred. The cure rates at the third, sixth,twelfth and twenty-fourth month were 65.1%, 96.2%, 98.1%, and 99.1% respectively; while in thecontrol group were 10.8%, 36.0%, 67.6% and 88.3% respectively. The difference was significant(P<0.01, <0.01, <0.01, <0.05). After the observation for 24 months, no relapse occurred in the SCAgroup, but 7 (6.3%) cases relapsed in control group (P<0.05).CONCLUSION The sclerotic agents should be used in sequence, i. e., a high concentration wasadministered to reduce and destroy the epithelium of the cysts, and to promote fiber tissue adhesion and thenthe remaining drug was used to stimulate epithelium to absorb the exudation. This combined regimen wasproved to be an ideal and effective method for treating hepatic cysts clinically.

    Tsekos, Nikolaos V; Khanicheh, Azadeh; Christoforou, Eftychios; Mavroidis, Constantinos


    The continuous technological progress of magnetic resonance imaging (MRI), as well as its widespread clinical use as a highly sensitive tool in diagnostics and advanced brain research, has brought a high demand for the development of magnetic resonance (MR)-compatible robotic/mechatronic systems. Revolutionary robots guided by real-time three-dimensional (3-D)-MRI allow reliable and precise minimally invasive interventions with relatively short recovery times. Dedicated robotic interfaces used in conjunction with fMRI allow neuroscientists to investigate the brain mechanisms of manipulation and motor learning, as well as to improve rehabilitation therapies. This paper gives an overview of the motivation, advantages, technical challenges, and existing prototypes for MR-compatible robotic/mechatronic devices.

    Cascella, Nicola G; Kryszak, Debra; Bhatti, Bushra; Gregory, Patricia; Kelly, Deanna L; Mc Evoy, Joseph P; Fasano, Alessio; Eaton, William W


    Celiac disease (CD) and schizophrenia have approximately the same prevalence, but epidemiologic data show higher prevalence of CD among schizophrenia patients. The reason for this higher co-occurrence is not known, but the clinical knowledge about the presence of immunologic markers for CD or gluten intolerance in schizophrenia patients may have implications for treatment. Our goal was to evaluate antibody prevalence to gliadin (AGA), transglutaminase (tTG), and endomysium (EMA) in a group of individuals with schizophrenia and a comparison group. AGA, tTG, and EMA antibodies were assayed in 1401 schizophrenia patients who were part of the Clinical Antipsychotic Trials of Intervention Effectiveness study and 900 controls. Psychopathology in schizophrenia patients was assessed using the Positive and Negative Symptoms Scale (PANSS). Logistic regression was used to assess the difference in the frequency of AGA, immunoglobulin A (IgA), and tTG antibodies, adjusting for age, sex, and race. Linear regression was used to predict PANSS scores from AGA and tTG antibodies adjusting for age, gender, and race. Among schizophrenia patients, 23.1% had moderate to high levels of IgA-AGA compared with 3.1% of the comparison group (χ(2) = 1885, df = 2, P gluten sensitivity.

    Kristian Laake


    Full Text Available Introduction. Fractalkine is a chemokine associated with atherosclerosis. Increased serum levels have been reported in unstable coronary artery disease (CAD and to predict mortality in heart failure. Mediterranean-like diet and omega-3 fatty acids (n3-PUFA have documented cardioprotective and anti-inflammatory effects. We have investigated the effect of Mediterranean-like dietary counseling and n-3 PUFA on serum fractalkine in an elderly population and its ability to predict cardiovascular disease (CVD. Materials and Methods. 563 men (age 64–75 yrs at high risk of CAD were randomized into a 2 × 2 factorial designed trial for 3-year dietary counseling and/or n-3 PUFA supplementation (2.4 g/d. Circulating levels of fractalkine were measured at baseline and at end of study. Clinical events were recorded after 3 years. Results. Fractalkine levels were significantly reduced in all groups from baseline to 3 years (P<0.001, all, but without between-group differences in changes. Fractalkine levels at baseline were not predictive for CVD events (n=68 or total mortality. Lower fractalkine levels were observed in smokers (P=0.019. Conclusions. Reduced levels of fractalkine from baseline to 3 years were observed, however, without any influence of Mediterranean-like diet or n-3 PUFA supplementation. Fractalkine levels at baseline were not predictive for later CVD events.

  10. Clinical intervention in aging: ethicolegal issues in assessing risk and benefit

    Directory of Open Access Journals (Sweden)

    Pierre Mallia


    Full Text Available Pierre MalliaMedical School, University of Malta, Mater Dei Hospital, MaltaAbstract: The ethical dimension of treating the elderly, including risk–benefit analysis, focuses mainly on quality of life and end-of-life issues. These include arguments on advance directives and the concept of extraordinary treatments. This paper looks more closely at the philosophical approach to aging in order to address questions on the direction of research and issues such as longevity and social construction of the aging process. It is the way society moves to understand the value-laden choices on aging that directs the goals of treatment and research. Whilst these vary culturally, one has to reckon with a postmodern view of aging which may, in turn, reflect on the course of action of future care and research in aging. The paper canvasses how, in reality, four principles act as guidelines for moral discourse, and discusses how changing values in society decide this course of action.Keywords: aging, principles, decision-making, conflict, treatment, clinical decision-making, social construction 

  11. Modelling household responses to energy efficiency interventions via system dynamics and survey data

    Directory of Open Access Journals (Sweden)

    S Davis


    Full Text Available An application of building a system dynamics model of the way households might respond to interventions aimed at reducing energy consumption (specifically the use of electricity is described in this paper. A literature review of past research is used to build an initial integrated model of household consumption, and this model is used to generate a small number of research hypotheses about how households possessing different characteristics might react to various types of interventions. These hypotheses are tested using data gathered from an efficiency intervention conducted in a town in the South African Western Cape in which households were able to exchange regular light bulbs for more efficient compact fluorescent lamp light bulbs. Our experiences are (a that a system dynamics approach proved useful in advancing a non-traditional point of view for which, for historical and economic reasons, data were not abundantly available; (b that, in areas where traditional models are heavily quantitative, some scepticism to a system dynamics model may be expected; and (c that a statistical comparison of model results by means of empirical data may be an effective tool in reducing such scepticism.

  12. Ethical and diversity challenges in ecologically sensitive systems-oriented interventions. (United States)

    Jason, Leonard A


    This article discusses ethical and diversity challenges involved in implementing ecologically sensitive, systems-oriented research. These issues are considered with reference to a series of community-based interventions dealing with stigma and chronic illness, recovery from substance-use disorders, and prevention of tobacco use. Each of these ecological interventions incorporates a systems approach, which allows an understanding of how individuals affect and are influenced by their social environments. In addition, issues of diversity with respect to underrepresented and marginalized groups are considered, including overcoming obstacles to gaining access to resources and promoting increased opportunities and empowerment. Throughout, the central importance of developing relationships with key gatekeepers and stakeholders, as well as timely and effective communications with various coalition members, is highlighted. By bringing into the research and policy process diverse citizen/participant suggestions and input regarding the need for, or design and implementation of ecologically and systems-based interventions, researchers can build collaborative relationships that fuel trust and partnerships, leading to more ethically responsible research.

    DeVoe, Ellen R; Paris, Ruth; Emmert-Aronson, Ben; Ross, Abigail; Acker, Michelle


    Objective: Parenting through the deployment cycle presents unique stressors for military families. To date, few evidence-based and military-specific parenting programs are available to support parenting through cycles of deployment separation and reintegration, especially for National Guard/Reserve members. The purpose of this research was to test the efficacy of a parenting program developed specifically to support military families during reintegration. Method: Within 1 year of returning from deployment to Afghanistan or Iraq, 115 service members with very young children were randomly assigned to receive either the Strong Families Strong Forces Parenting Program at baseline or after a 12-week waiting period. Using a home-based modality, service members, at-home parents, and their young child were assessed at baseline, 3 months posttreatment/wait period, and 6 months from baseline. Results: Service member parents in Strong Families evidenced greater reductions in parenting stress and mental health distress relative to those in the waitlist comparison group. Service members with more posttraumatic stress symptoms reported higher levels of perceived parental efficacy in the intervention group than service members in the comparison group. Intervention also resulted in enhanced parental reflective capacity, including increased curiosity and interest in the young child among those in the intervention group relative to comparison. Conclusion: Service member parents and their spouses demonstrated high interest in participating in a postdeployment parenting program targeting families with very young children. Findings point to the feasibility, appeal, and efficacy of Strong Families in this initial trial and suggest promise for implementation in broader military and community service systems.

    王少玲; 黄金月; 周家仪


    Intervention design is a key link in an experimental research and may directly affect the quality and outcomes of care and research. Effective nursing interventions are developed through a systematic and rigorous process. With authors own experience in designing nursing interventions, this article recommends three main steps for developing intervention protocols in nursing clinical trials. They are: ①to establish a conceptual framework for interventions with the regard to the indentiifed research problem;②to develop evidence-based intervention protocols along with careful consideration of the intervention target, delivery methods, intervention property, intervention dose (including components, amount, frequency and duration of nursing care), interventionists and intervention management;③to validate and take pilot test of the protocols before their actual usage in the main study.%干预方案的设计是实验性研究中的一个重要环节,直接影响护理和研究的质量和结局。有效护理干预方案的制定须经历一个严谨的过程。本文借助笔者的设计经验提出护理临床研究中干预方案的制定的三个重要步骤:①围绕研究主题建立干预的概念框架;②建立以循证为基础的干预方案,包含目标群体、实施方法、干预特性、护理剂量(成分、数量、频次和周期)、干预者和干预管理;③实施前对干预方案进行审核和测试。

    Kim, Jeesu; Park, Sara; Jung, Yuhan; Chang, Sunyeob; Park, Jinyong; Zhang, Yumiao; Lovell, Jonathan F; Kim, Chulhong


    Photoacoustic imaging has attracted interest for its capacity to capture functional spectral information with high spatial and temporal resolution in biological tissues. Several photoacoustic imaging systems have been commercialized recently, but they are variously limited by non-clinically relevant designs, immobility, single anatomical utility (e.g., breast only), or non-programmable interfaces. Here, we present a real-time clinical photoacoustic and ultrasound imaging system which consists of an FDA-approved clinical ultrasound system integrated with a portable laser. The system is completely programmable, has an intuitive user interface, and can be adapted for different applications by switching handheld imaging probes with various transducer types. The customizable photoacoustic and ultrasound imaging system is intended to meet the diverse needs of medical researchers performing both clinical and preclinical photoacoustic studies.

    Full Text Available Early intervention services and lekoteks in Moscow preschool education system are aimed to help children from several months to 7 years of age with developmental disorders and their parents. The number of such programs reached 200 in 2012 and was growing faster than the number of professionals skilled to work at them. This obvious mismatch situation emerged the need for quality assessment and structured educational programs for specialist initial education and recertification. In this article we discuss the most commonly used protocols in early intervention programs, and current trends in their improvement. We also propose a model for quality standard development in early intervention services and lekoteks, based on worldwide experience and ISO (ISO 9001:2000 quality management principles.

  20. Changes in actual and perceived physical abilities in clinically obese children: a 9-month multi-component intervention study.

    Milena Morano

    Full Text Available OBJECTIVES: (1 To examine relationships among changes in physical activity, physical fitness and some psychosocial determinants of activity behavior in a clinical sample of obese children involved in a multi-component program; (2 to investigate the causal relationship over time between physical activity and one of its strongest correlates (i.e. perceived physical ability. METHODS: Self-reported physical activity and health-related fitness tests were administered before and after a 9-month intervention in 24 boys and 20 girls aged 8 to 11 years. Individuals' perceptions of strength, speed and agility were assessed using the Perceived Physical Ability Scale, while body image was measured using Collins' Child Figure Drawings. RESULTS: Findings showed that body mass index, physical activity, performances on throwing and weight-bearing tasks, perceived physical ability and body image significantly improved after treatment among obese children. Gender differences were found in the correlational analyses, showing a link between actual and perceived physical abilities in boys, but not in girls. For the specific measurement interval of this study, perception of physical ability was an antecedent and not a potential consequence of physical activity. CONCLUSIONS: Results indicate that a multi-component activity program not based merely on a dose-effect approach enhances adherence of the participants and has the potential to increase the lifelong exercise skills of obese children. Rather than focusing entirely on diet and weight loss, findings support the inclusion of interventions directed toward improving perceived physical ability that is predictive of subsequent physical activity.

  1. Nonattendance at a hospital-based otolaryngology clinic: a preliminary analysis within a universal healthcare system. (United States)

    Zirkle, Molly S; McNelles, Laurie R


    Missed appointments at specialty clinics generate concerns for physicians and clinic administrators. Appointment nonattendance obstructs the provision of timely medical interventions and the maximization of systemic efficiencies. Yet, empiric study of factors associated with missed appointments at adult specialty clinics has received little attention in North America. We conducted a preliminary study of otolaryngology clinic nonattendance in the context of a universal healthcare system environment in Canada. Our data were based on the schedule of 1,512 new patient appointments at a hospital-based clinic from May 1 through Sept. 30, 2008. Gathered information included the employment status of the attending physician (i.e., full-time vs. part-time), the patient's sex and age, the day of the week and the time of the appointment, and the attendance status. We found that the rate of nonattendance was 24.4% (n = 369). Nonattendance rates varied significantly according to physician employment status (more common for part-time physicians), patient sex (women) and age (younger adults), and the day of the appointment (Wednesdays), but not according to the time of day. Our findings suggest that there are predictable patient and systemic factors that influence nonattendance at medical appointments. Awareness of these factors can have implications for the delivery of healthcare services within a universal healthcare context.

    Directory of Open Access Journals (Sweden)

    Maarten Janssen


    Full Text Available Osteoarthritis (OA is a big burden of disease worldwide and one of the most common causes of disability in the adult population. Currently applied therapies consist of physical therapy, oral medication, intra-articular injections, and surgical interventions, with the main goal being to reduce pain and improve function and quality of life. Intra-articular (IA administration of drugs has potential benefits in OA treatment because it minimizes systemic bioavailability and side effects associated with oral administration of drugs without compromising the therapeutic effect in the joint. However, IA drug residence time is short and there is a clinical need for a vehicle that is able to provide a sustained release long enough for IA therapy to fulfill its promise. This review summarizes the use of different polymeric systems and the incorporated drugs for IA drug delivery in the osteoarthritic joint with a primary focus on clinical needs and opportunities.

    Full Text Available Abstract Background The aim of the present study was to assess possible effects on mental and physical well-being and stress-related biological markers of a web-based health promotion tool. Methods A randomized, prospectively controlled study was conducted with before and after measurements, involving 303 employees (187 men and 116 women, age 23–64 from four information technology and two media companies. Half of the participants were offered web-based health promotion and stress management training (intervention lasting for six months. All other participants constituted the reference group. Different biological markers were measured to detect possible physiological changes. Results After six months the intervention group had improved statistically significantly compared to the reference group on ratings of ability to manage stress, sleep quality, mental energy, concentration ability and social support. The anabolic hormone dehydroepiandosterone sulphate (DHEA-S decreased significantly in the reference group as compared to unchanged levels in the intervention group. Neuropeptide Y (NPY increased significantly in the intervention group compared to the reference group. Chromogranin A (CgA decreased significantly in the intervention group as compared to the reference group. Tumour necrosis factor α (TNFα decreased significantly in the reference group compared to the intervention group. Logistic regression analysis revealed that group (intervention vs. reference remained a significant factor in five out of nine predictive models. Conclusion The results indicate that an automatic web-based system might have short-term beneficial physiological and psychological effects and thus might be an opportunity in counteracting some clinically relevant and common stress and health issues of today.

  6. Therapeutic intervention at cellular quality control systems in Alzheimer's and Parkinson's diseases. (United States)

    Arduino, Daniela M; Esteves, A Raquel; Silva, Diana F F; Martins-Branco, Diogo; Santos, Daniel; Pimentel, Diana F Gomes; Cardoso, Sandra M


    Cellular homeostasis relies on quality control systems so that damaged biologic structures are either repaired or degraded and entirely replaced by newly formed proteins or even organelles. The clearance of dysfunctional cellular structures in long-lived postmitotic cells, like neurons, is essential to eliminate, per example, defective mitochondria, lipofuscin-loaded lysosomes and oxidized proteins. Short-lived proteins are degraded mainly by proteases and proteasomes whether most long-lived proteins and all organelles are digested by autophagy in the lysosomes. Recently, it an interplay was established between the ubiquitin-proteasome system and macroautophagy, so that both degradative mechanisms compensate for each other. In this article we describe each of these clearance systems and their contribution to neuronal quality control. We will highlight some of the findings that provide evidence for the dysfunction of these systems in Alzheimer's and Parkinson's diseases. Ultimately, we provide an outline on potential therapeutic interventions based on the modulation of cellular degradative systems.

    Objective: To evaluate the effect of Xiongshao Capsule (XS, 芎芍胶囊) in preventing clinical and angiographic restenosis after coronary angioplasty or/and stenting. Methods: The total of 108 coronary heart disease patients with successful coronary angioplasty or/and stenting were randomly divided into the control group (55 cases, routine treatment) and the XS group (53 cases, routine treatment combined with XS). The recurrence of angina, clinical end-point events, changing of blood-stasis syndrome score (BSSS) and coronary angiography within 6 month after coronary angioplasty or/and stenting were observed. Results: Follow-up angiography was performed in 42 patients including 18 cases in the XS group (restenosis was observed in 7 patients) and 24 cases in the control group (restenosis was observed in 17 patients), there was significant difference between the occurrence of restenosis in XS and that in control group (P<0.05). The occurrence of clinical end-point events (death, nonfatal target lesion myocardial infarction, coronary artery bypass graft surgery, or repeat target-vessel angioplasty) in the XS group (18.8%) was significantly lower than that in the control group (40%)(P<0.05). The recurrent angina was observed in 13 cases in the XS group, there was significant difference as compared with 27 cases in the control group (P<0.05). There was also remarkable significance for the difference of base-line and follow-up BSSS between groups (P<0.01). Logistic multivariate stepwise regress analysis and multivariate regress analysis of the related factors with restenosis confirmed by coronary angiography showed that, the base-line BSSS and the difference of base-line and follow-up BSSS were important influencing factors on the occurrence of restenosis after interventional treatment (P<0.05). Conclusion: XS could markedly reduce the occurrence of angiographic restenosis, clinical end-point events and recurrent angina, improve condition of blood-stasis after coronary

    Directory of Open Access Journals (Sweden)

    Alcacer-Pitarch Begonya


    Full Text Available Abstract Background Foot problems associated with Systemic Sclerosis (SSc/Scleroderma have been reported to be both common and disabling. There are only limited data describing specifically, the mechanical changes occurring in the foot in SSc. A pilot project conducted in preparation for this trial confirmed the previous reports of foot related impairment and reduced foot function in people with SSc and demonstrated a link to mechanical etiologies. To-date there have been no formal studies of interventions directed at the foot problems experienced by people with Systemic Sclerosis. The primary aim of this trial is to evaluate whether foot pain and foot-related health status in people with Systemic Sclerosis can be improved through the provision of a simple pressure-relieving insole. Methods The proposed trial is a pragmatic, multicenter, randomised controlled clinical trial following a completed pilot study. In four participating centres, 140 consenting patients with SSc and plantar foot pain will be randomised to receive either a commercially available pressure relieving and thermally insulating insole, or a sham insole with no cushioning or thermal properties. The primary end point is a reduction in pain measured using the Foot Function Index Pain subscale, 12 weeks after the start of intervention. Participants will complete the primary outcome measure (Foot Function Index pain sub-scale prior to randomisation and at 12 weeks post randomisation. Secondary outcomes include participant reported pain and disability as derived from the Manchester Foot Pain and Disability Questionnaire and plantar pressures with and without the insoles in situ. Discussion This trial protocol proposes a rigorous and potentially significant evaluation of a simple and readily provided therapeutic approach which, if effective, could be of a great benefit for this group of patients.

    Full Text Available Background: Parents of children with cancer experience high levels of stress and discomfort. Religious beliefs are important sources of comfort and support for many cancer patients and their families. The present study aimed to assess the effect of educational-spiritual intervention on burnout of the parents of the children with cancer. Methods: In this randomized clinical trial, 135 parents of children with cancer were randomly assigned into intervention and control groups. Data were collected through SMBQ (Shirom and Melamed Burnout Questionnaire from both groups, before, immediately after and one month after the intervention. Educational-spiritual programs were held for six weeks, one session every week. The data were analyzed by SPSS using independent t-test, and repeated measure ANOVA. Results: The results showed that the mean burnout score before the intervention in the intervention group was 4.28±0.61 and in the control group it was 4.23±0.50; most of the parents reported moderate to high burnout. But, there was a significant difference between the intervention and control groups immediately after and one month after the intervention (t=10.16, P<0.0001. The mean burnout score in the intervention group was less than the control group. Results also showed that there was a significant difference between the two groups in terms of parental burnout in three times of measurements (F=58.62, P<0.0001. Conclusion: This study indicated that educational-spiritual intervention was effective on reduction of the burnout of the parents of the children with cancer. Due to high burnout of most of the parents, offering such a program could be beneficial for them. More studies in this regard are recommended.

  13. Development of an auxiliary system for the execution of vascular catheter interventions with a reduced radiological risk; system description and first experimental results. (United States)

    Placidi, Giuseppe; Franchi, Danilo; Marsili, Luca; Gallo, Pasquale


    Vascular catheterization is a common procedure in clinical medicine. It is normally performed by a specialist using an X-ray fluoroscopic guide and contrast-media. In the present paper, an image-guided navigation system which indicates a path providing guidance to the desired target inside the vascular tree is described with the aim of reducing the exposure of personnel and patients to X-rays during the catheterization procedure. A 3D model of the patient vascular tree, reconstructed with data collected by an angiography before starting the intervention, is used as a guide map instead of fluoroscopic scans. An accurate spatial correspondence between the body of the patient and the 3D reconstructed vascular model is established and, by means of a position indicator installed over the catheter tip, the real-time position/orientation of the tip is indicated correctly. This paper describes the system and the operational procedures necessary to use the proposed method efficiently during a catheter intervention. Preliminary experimental results on a phantom are also reported.

  15. Representing clinical communication knowledge through database management system integration. (United States)

    Khairat, Saif; Craven, Catherine; Gong, Yang


    Clinical communication failures are considered the leading cause of medical errors [1]. The complexity of the clinical culture and the significant variance in training and education levels form a challenge to enhancing communication within the clinical team. In order to improve communication, a comprehensive understanding of the overall communication process in health care is required. In an attempt to further understand clinical communication, we conducted a thorough methodology literature review to identify strengths and limitations of previous approaches [2]. Our research proposes a new data collection method to study the clinical communication activities among Intensive Care Unit (ICU) clinical teams with a primary focus on the attending physician. In this paper, we present the first ICU communication instrument, and, we introduce the use of database management system to aid in discovering patterns and associations within our ICU communications data repository.

    Bojalil, R; Guiscafré, H; Espinosa, P; Viniegra, L; Martínez, H; Palafox, M; Gutiérrez, G


    In Tlaxcala State, Mexico, we determined that 80% of children who died from diarrhoea or acute respiratory infections (ARI) received medical care before death; in more than 70% of the cases this care was provided by a private physician. Several strategies have been developed to improve physicians' primary health care practices but private practitioners have only rarely been included. The objective of the present study was to evaluate the impact of in-service training on the case management of diarrhoea and ARI among under-5-year-olds provided by private and public primary physicians. The training consisted of a five-day course of in-service practice during which physicians diagnosed and treated sick children attending a centre and conducted clinical discussions of cases under guidance. Each training course was limited to six physicians. Clinical performance was evaluated by observation before and after the courses. The evaluation of diarrhoea case management covered assessment of dehydration, hydration therapy, prescription of antimicrobial and other drugs, advice on diet, and counselling for mothers; that of ARI case management covered diagnosis, decisions on antimicrobial therapy, use of symptomatic drugs, and counselling for mothers. In general the performance of public physicians both before and after the intervention was better than that of private doctors. Most aspects of the case management of children with diarrhoea improved among both groups of physicians after the course; the proportion of private physicians who had five or six correct elements out of six increased from 14% to 37%: for public physicians the corresponding increase was from 53% to 73%. In ARI case management, decisions taken on antimicrobial therapy and symptomatic drug use improved in both groups; the proportion of private physicians with at least three correct elements out of four increased from 13% to 42%, while among public doctors the corresponding increase was from 43% to 78%.

  17. Semantic Interoperability in Clinical Decision Support Systems: A Systematic Review. (United States)

    Marco-Ruiz, Luis; Bellika, Johan Gustav


    The interoperability of Clinical Decision Support (CDS) systems with other health information systems has become one of the main limitations to their broad adoption. Semantic interoperability must be granted in order to share CDS modules across different health information systems. Currently, numerous standards for different purposes are available to enable the interoperability of CDS systems. We performed a literature review to identify and provide an overview of the available standards that enable CDS interoperability in the areas of clinical information, decision logic, terminology, and web service interfaces.

    Kerby, Tessa; Schneider, Nicole; Asche, Stephen; Loes, Linda; Maciosek, Michael; Meyers, Peter; Michalski, Derek; Margolis, Karen


    Background/Aims: Designing a seamless data collection tool for a research study across multiple physical locations within a health care system is challenging. Paper-based data collection is prone to data entry errors, subject to delays in availability of data, and environmentally wasteful. Web-based data collection tools are costly, time consuming to produce, and have security issues. We used Microsoft Access to create an efficient, low-cost electronic data collection tool for a clinical trial that required availability at numerous locations in the HealthPartners system. Methods: The research study required data collection entry points at ten different locations for different types of users, all linked into the HealthPartners computer network. A single Access database with linked modules for recruitment, tracking, eligibility determination and data collection was designed. Results: The recruitment module used at the research department integrated data on recruitment mailings and telephone screening of interested respondents, and used an automated algorithm to perform eligibility checks. The research clinic module for clinic visits was populated with eligible participants as determined by the recruitment module. This clinic module included further eligibility checks, data collection and treatment assignment. Participants then became available in the intervention module to pharmacist case managers located at 8 HealthPartners primary care clinics to collect data for the intervention. Based on study entry date, Access created a visit log to aid the case managers with timely adherence to the trial protocol. The database is stored on a secure server that is accessible only to authorized study team members, with further restrictions on data entry and access determined by study team role. Conclusions: The disadvantages of Microsoft Access (lack of flexibility, “bugginess”, older technology) are counterbalanced by many advantages (ready availability, inexpensiveness

  19. Compliance of an elderly hip fracture population with secondary preventative measures. Efficacy of a simple clinical practice intervention.

    LENUS (Irish Health Repository)

    Street, John


    Secondary pharmaceutical measures are effective in all age groups for the prevention of osteoporotic fractures. This prospective study determines the demographics of 566 consecutive osteoporotic hip fractures presenting to a Level 1 Trauma Center. We examine the efficacy of simple treatment recommendations for pharmaceutical treatment of osteoporosis and the factors determining general practitioner and patient compliance with these recommendations in a community setting. One out of four patients (24.5%) had sustained a previous fragility fracture. Mean age was 80 years. Twenty five percent were resident in a nursing home and only 10% were taking anti-resorptive therapy preoperatively. In hospital mortality was 6%, and 39% of recruited patients were dead at 12 months. By this time more than half the survivors were resident in a nursing home. The compliance with anti-resorptive therapy had increased to over 70% consequent to our simple recommendations. Significant differences in GP and patient compliance were observed between nursing home and own residence dwellers. This study demonstrates the efficacy of a simple clinical practice intervention in increasing patient and GP compliance with secondary fracture prevention measures. We also discuss many of the confounding issues determining this compliance.

  20. What is the right time for supportive versus expressive interventions in supervision? An illustration based on a clinical mistake. (United States)

    Leibovich, Liat; Zilcha-Mano, Sigal


    Although supportive-expressive (SE) psychotherapy is one of the most studied psychodynamic therapies today, little is known empirically about effective strategies in SE supervision, or in psychodynamic supervision in general (Diener & Mesrie, 2015; Watkins, 2011). One of the important questions in SE psychotherapy is how to decide when to use supportive and when to use expressive interventions. As a parallel process, this type of decision is relevant also to SE supervision. The present case study focuses on the decision-making process in an SE supervision session: when should supervisors use supportive as opposed to expressive strategies with their supervisees? Our aim is to develop decision rules that reliably support supervisors' decisions. We analyze a clinical error made by supervisors in this type of decision making, and show how mistakes of this type can either be avoided or, when they occur, how to turn them into opportunities for learning and for the formation of new understanding and growth. Similarly to the finding that therapists with better skills in managing their countertransference feelings were shown to have better outcomes with their patients (Gelso, Latts, Gomez, & Fassinger, 2002; Hayes, Gelso, & Hummel, 2011), we suggest that the management of the supervisors' feelings, and working through their mistakes with the therapists, can contribute to the supervisory relationship and to the development of the psychodynamic therapists' skills.

    Stephen Honeybul

    Full Text Available BACKGROUND: Decompressive craniectomy has been traditionally used as a lifesaving rescue treatment in severe traumatic brain injury (TBI. This study assessed whether objective information on long-term prognosis would influence healthcare workers' opinion about using decompressive craniectomy as a lifesaving procedure for patients with severe TBI. METHOD: A two-part structured interview was used to assess the participants' opinion to perform decompressive craniectomy for three patients who had very severe TBI. Their opinion was assessed before and after knowing the predicted and observed risks of an unfavourable long-term neurological outcome in various scenarios. RESULTS: Five hundred healthcare workers with a wide variety of clinical backgrounds participated. The participants were significantly more likely to recommend decompressive craniectomy for their patients than for themselves (mean difference in visual analogue scale [VAS] -1.5, 95% confidence interval -1.3 to -1.6, especially when the next of kin of the patients requested intervention. Patients' preferences were more similar to patients who had advance directives. The participants' preferences to perform the procedure for themselves and their patients both significantly reduced after knowing the predicted risks of unfavourable outcomes, and the changes in attitude were consistent across different specialties, amount of experience in caring for similar patients, religious backgrounds, and positions in the specialty of the participants. CONCLUSIONS: Access to objective information on risk of an unfavourable long-term outcome influenced healthcare workers' decision to recommend decompressive craniectomy, considered as a lifesaving procedure, for patients with very severe TBI.

  3. Implementation of a school-based social and emotional learning intervention: understanding diffusion processes within complex systems. (United States)

    Evans, Rhiannon; Murphy, Simon; Scourfield, Jonathan


    Sporadic and inconsistent implementation remains a significant challenge for social and emotional learning (SEL) interventions. This may be partly explained by the dearth of flexible, causative models that capture the multifarious determinants of implementation practices within complex systems. This paper draws upon Rogers (2003) Diffusion of Innovations Theory to explain the adoption, implementation and discontinuance of a SEL intervention. A pragmatic, formative process evaluation was conducted in alignment with phase 1 of the UK Medical Research Council's framework for Developing and Evaluating Complex Interventions. Employing case-study methodology, qualitative data were generated with four socio-economically and academically contrasting secondary schools in Wales implementing the Student Assistance Programme. Semi-structured interviews were conducted with 15 programme stakeholders. Data suggested that variation in implementation activity could be largely attributed to four key intervention reinvention points, which contributed to the transformation of the programme as it interacted with contextual features and individual needs. These reinvention points comprise the following: intervention training, which captures the process through which adopters acquire knowledge about a programme and delivery expertise; intervention assessment, which reflects adopters' evaluation of an intervention in relation to contextual needs; intervention clarification, which comprises the cascading of knowledge through an organisation in order to secure support in delivery; and intervention responsibility, which refers to the process of assigning accountability for sustainable delivery. Taken together, these points identify opportunities to predict and intervene with potential implementation problems. Further research would benefit from exploring additional reinvention activity.

  4. Conceptualization of an electronic system for documentation of nursing diagnosis, outcomes, and intervention. (United States)

    Peres, Heloisa Helena Ciqueto; de Almeida Lopes Monteiro da Cruz, Diná; Lima, Antônio Fernandes Costa; Gaidzinski, Raquel Rapone; Ortiz, Diley Cardoso Franco; Mendes e Trindade, Michelle; Tsukamoto, Rosangela; Batista de Oliveira, Neurilene


    Electronic nursing documentation constitutes technical, scientific, legal, and ethical documents. The objective of this study was to develop an electronic nursing documentation system. The system was developed in four phases (conceptualization, detailing, prototype building, implementation), and the knowledge base was based on domains and classes according to the NANDA-I, NIC, and NOC unified framework. The result is an electronic system (PROCEnf--USP--Nursing Process Electronic Documentation System of the University of São Paulo) which allows documenting nursing process generating reports of nursing process, besides supporting decisions on nursing diagnosis, expected outcomes, and interventions. Integration of different fields of knowledge, as well as the institutional feature of valuing continuous theoretical and practical improvement of nursing process were factors of success of this technological project.

  5. Semantically based clinical TCM telemedicine systems

    Wong, Allan K Y; Lin, Wilfred W K; Dillon, Tharam S; Chang, Elizabeth J


    Recent years have seen the development of two significant trends namely: the adoption of some Traditional Chinese Medicine Practices into mainstream Allopathic Western Medicine and the advent of the internet and broad band networks leading to an increased interest in the use of Telemedicine to deliver medical services. In this book, we see the convergence of these two trends leading to a semantically-based TCM Telemedicine system that utilizes an ontology to provide sharable knowledge in the TCM realm to achieve this. The underpinning research required the development of a three-layer architecture and an Ontology of the TCM knowledge. As TCM knowledge like all medical knowledge is not frozen in time it was important to develop an approach that would allow evolution of the Ontology when new evidence became available. In order for the system to be practically grounded it was important to work with an industry partner PuraPharm Group/HerbMiners Informatics Limited. This partnership was initiated through Professo...

  6. Toward an evaluation of an integrated clinical imaging system: identifying clinical benefits. (United States)

    Kaplan, B; Lundsgaarde, H P


    Integrated clinical imaging systems can provide the foundation for future computer-based patient record systems as recommended by the Institute of Medicine. However, documenting the benefits of such systems is difficult. This paper reports an evaluation of a clinical imaging system that is integrated with an on-line electronic patient record. The evaluation used interviews and observations to identify what physicians thought were the benefits of this system. Reported benefits may be classified into patient care benefits, educational benefits, and productivity and cost-reduction benefits Physicians said that the imaging system provided patient care benefits by: improving clinical communication and decision making, making care more patient-based, reducing the number of procedures and patient risks, and improving record keeping. Educational benefits they reported included: improving communication, providing broad "real" experience, and improving supervision. These benefits may be reflected in increased productivity and cost reduction by increasing time savings, reducing clerical work, improving morale, and reducing the costs of care. The approach described in this study was valuable in identifying potential benefits of a clinical information system. The findings point the way to realization of benefits for other systems, and, ultimately, for computer-based patient records.

  7. Incorporating an Early Detection System Into Routine Clinical Practice in Two Community Hospitals. (United States)

    Dummett, B Alex; Adams, Carmen; Scruth, Elizabeth; Liu, Vincent; Guo, Margaret; Escobar, Gabriel J


    Efforts to improve outcomes of patients who deteriorate outside the intensive care unit have included the use of rapid response teams (RRTs) as well as manual and automated prognostic scores. Although automated early warning systems (EWSs) are starting to enter clinical practice, there are few reports describing implementation and the processes required to integrate early warning approaches into hospitalists' workflows. We describe the implementation process at 2 community hospitals that deployed an EWS. We employed the Institute for Healthcare Improvement's iterative Plan-Do-Study-Act approach. Our basic workflow, which relies on having an RRT nurse and the EWS's 12-hour outcome time frame, has been accepted by clinicians and has not been associated with patient complaints. Whereas our main objective was to develop a set of workflows for integrating the electronic medical record EWS into clinical practice, we also uncovered issues that must be addressed prior to disseminating this intervention to other hospitals. One problematic area is that of documentation following an alert. Other areas that must be addressed prior to disseminating the intervention include the need for educating clinicians on the rationale for deploying the EWS, careful consideration of interdepartment service agreements, clear definition of clinician responsibilities, pragmatic documentation standards, and how to communicate with patients. In addition to the deployment of the EWS to other hospitals, a future direction for our teams will be to characterize process-outcomes relationships in the clinical response itself.

  8. Smart-card-based automatic meal record system intervention tool for analysis using data mining approach. (United States)

    Zenitani, Satoko; Nishiuchi, Hiromu; Kiuchi, Takahiro


    The Smart-card-based Automatic Meal Record system for company cafeterias (AutoMealRecord system) was recently developed and used to monitor employee eating habits. The system could be a unique nutrition assessment tool for automatically monitoring the meal purchases of all employees, although it only focuses on company cafeterias and has never been validated. Before starting an interventional study, we tested the reliability of the data collected by the system using the data mining approach. The AutoMealRecord data were examined to determine if it could predict current obesity. All data used in this study (n = 899) were collected by a major electric company based in Tokyo, which has been operating the AutoMealRecord system for several years. We analyzed dietary patterns by principal component analysis using data from the system and extracted 5 major dietary patterns: healthy, traditional Japanese, Chinese, Japanese noodles, and pasta. The ability to predict current body mass index (BMI) with dietary preference was assessed with multiple linear regression analyses, and in the current study, BMI was positively correlated with male gender, preference for "Japanese noodles," mean energy intake, protein content, and frequency of body measurement at a body measurement booth in the cafeteria. There was a negative correlation with age, dietary fiber, and lunchtime cafeteria use (R(2) = 0.22). This regression model predicted "would-be obese" participants (BMI >or= 23) with 68.8% accuracy by leave-one-out cross validation. This shows that there was sufficient predictability of BMI based on data from the AutoMealRecord System. We conclude that the AutoMealRecord system is valuable for further consideration as a health care intervention tool.

  9. Salmonella internalization in mung bean sprouts and pre- and postharvest intervention methods in a hydroponic system. (United States)

    Ge, Chongtao; Rymut, Susan; Lee, Cheonghoon; Lee, Jiyoung


    Mung bean sprouts, typically consumed raw or minimally cooked, are often contaminated with pathogens. Internalized pathogens pose a high risk because conventional sanitization methods are ineffective for their inactivation. The studies were performed (i) to understand the potential of internalization of Salmonella in mung bean sprouts under conditions where the irrigation water was contaminated and (ii) to determine if pre- and postharvest intervention methods are effective in inactivating the internalized pathogen. Mung bean sprouts were grown hydroponically and exposed to green fluorescence protein-tagged Salmonella Typhimurium through maturity. One experimental set received contaminated water daily, while other sets received contaminated water on a single day at different times. For preharvest intervention, irrigation water was exposed to UV, and for postharvest intervention-contaminated sprouts were subjected to a chlorine wash and UV light. Harvested samples were disinfected with ethanol and AgNO3 to differentiate surface-associate pathogens from the internalized ones. The internalized Salmonella Typhimurium in each set was quantified using the plate count method. Internalized Salmonella Typhimurium was detected at levels of 2.0 to 5.1 log CFU/g under all conditions. Continuous exposure to contaminated water during the entire period generated significantly higher levels of Salmonella Typhimurium internalization than sets receiving contaminated water for only a single day (P < 0.05). Preintervention methods lowered the level of internalized Salmonella by 1.84 log CFU/g (P < 0.05), whereas postintervention methods were ineffective in eliminating internalized pathogens. Preintervention did not completely inactivate bacteria in sprouts and demonstrated that the remaining Salmonella Typhimurium in water became more resistant to UV. Because postharvest intervention methods are ineffective, proper procedures for maintaining clean irrigation water must be followed

  10. Effectiveness of personalized face-to-face and telephone nursing counseling interventions for cardiovascular risk factors: a controlled clinical trial 1 (United States)

    Vílchez Barboza, Vivian; Klijn, Tatiana Paravic; Salazar Molina, Alide; Sáez Carrillo, Katia Lorena


    Abstract Objective: to evaluate the effect and gender differences of an innovative intervention involving in-person and telephone nursing counseling to control cardiovascular risk factors (arterial hypertension, dyslipidemia, and overweight), improve health-related quality of life and strengthen self-efficacy and social support in persons using the municipal health centers' cardiovascular health program. Method: a randomized controlled clinical trial involving participants randomized into the intervention group who received traditional consultation plus personalized and telephone nursing counseling for 7 months (n = 53) and the control group (n = 56). The study followed the Consolidated Standards of Reporting Trials Statement. Results: women in the intervention group presented a significant increase in the physical and mental health components compared to the control group, with decreases in weight, abdominal circumference, total cholesterol, low-density lipoprotein cholesterol, and the atherogenic index. The effects attributable to the intervention in the men in the intervention group were increased physical and emotional roles and decreased systolic and diastolic pressure, waist circumference, total cholesterol, low-density lipoprotein cholesterol, atherogenic index, cardiovascular risk factor, and 10-year coronary risk. Conclusion: this intervention is an effective strategy for the control of three cardiovascular risk factors and the improvement of health-related quality of life. PMID:27508917

  11. Development of a clinical data warehouse from an intensive care clinical information system. (United States)

    de Mul, Marleen; Alons, Peter; van der Velde, Peter; Konings, Ilse; Bakker, Jan; Hazelzet, Jan


    There are relatively few institutions that have developed clinical data warehouses, containing patient data from the point of care. Because of the various care practices, data types and definitions, and the perceived incompleteness of clinical information systems, the development of a clinical data warehouse is a challenge. In order to deal with managerial and clinical information needs, as well as educational and research aims that are important in the setting of a university hospital, Erasmus Medical Center Rotterdam, The Netherlands, developed a data warehouse incrementally. In this paper we report on the in-house development of an integral part of the data warehouse specifically for the intensive care units (ICU-DWH). It was modeled using Atos Origin Metadata Frame method. The paper describes the methodology, the development process and the content of the ICU-DWH, and discusses the need for (clinical) data warehouses in intensive care.

    Directory of Open Access Journals (Sweden)

    Smit Filip


    Full Text Available Abstract Background Depressive and anxiety symptoms in older adults could develop into significant health problems with detrimental effects on quality of life and a possibly poor prognosis. Therefore, there is a need for preventive interventions which are at once effective, acceptable and economic affordable. Methods and design This paper describes the design of a study evaluating "The stories we live by", a preventive life-review group intervention, which was recently developed for adults of 55 years and over with depressive and anxiety symptoms. Both clinical and economic effectiveness will be evaluated in a pragmatic randomized controlled trial. The participants in the intervention condition will receive the 8-session preventive intervention. The participants in the control condition will have access to usual care. Clinical end-terms are depressive and anxiety symptoms, current major depressive episode, quality of life and positive mental health post-treatment (3 months after baseline and at follow-ups (6 and 12 months after baseline. Additional goals of this study are to identify groups for whom the intervention is particularly effective and to identify the therapeutic pathways that are vital in inducing clinical change. This will be done by analyzing if treatment response is moderated by demographics, personality, past major depressive episodes, important life events and chronically disease, and mediated by reminiscence functions, perceived control, automatic positive thoughts and meaning in life. Finally the cost-effectiveness of the intervention relative to care as usual will be assessed by computing incremental costs per case of depression and anxiety avoided (cost-effectiveness and per quality adjusted life year (QALY (cost utility. Discussion It is expected that both the life-review intervention and its evaluation will contribute to the existing body of knowledge in several ways. First, the intervention is unique in linking life

  13. Almanac 2012: interventional cardiology. The national society journals present selected research that has driven recent advances in clinical cardiology

    Directory of Open Access Journals (Sweden)

    Meier Pascal


    Full Text Available The field of interventional cardiology continues to progress quickly. The efficacy of percutaneous interventions with newer generation drug-eluting stents has advanced a lot over the last decade. This improvement in stent performance has broadened the level of indication towards more complex interventions such as left main and multivessel PCI. Major improvements continue in the field of medical co-therapy such as antiplatelet therapies (bivalirudin, prasugrel, ticagrelor and this will further improve outcomes of PCI. The same is true for intravascular imaging such as ultrasound IVUS and optical coherence tomography OCT. However, interventional cardiology has become a rather broad field, also including alcohol septal ablation for hypertrophic obstructive cardiomyopathy, etc. At the moment, the fastest growing area is the structural interventions, especially for aortic valve stenosis (transcatheter aortic valve implantation TAVI and for mitral regurgitation (mitral clipping.This review covers recent advances in all these different fields of interventional cardiology.

    Full Text Available Abstract Background A four-year action research study was conducted across the Australian Capital Territory health system to strengthen interprofessional collaboration (IPC though multiple intervention activities. Methods We developed 272 substantial IPC intervention activities involving 2,407 face-to-face encounters with health system personnel. Staff attitudes toward IPC were surveyed yearly using Heinemann et al's Attitudes toward Health Care Teams and Parsell and Bligh's Readiness for Interprofessional Learning scales (RIPLS. At study's end staff assessed whether project goals were achieved. Results Of the improvement projects, 76 exhibited progress, and 57 made considerable gains in IPC. Educational workshops and feedback sessions were well received and stimulated interprofessional activities. Over time staff scores on Heinemann's Quality of Interprofessional Care subscale did not change significantly and scores on the Doctor Centrality subscale increased, contrary to predictions. Scores on the RIPLS subscales of Teamwork & Collaboration and Professional Identity did not alter. On average for the assessment items 33% of staff agreed that goals had been achieved, 10% disagreed, and 57% checked neutral. There was most agreement that the study had resulted in increased sharing of knowledge between professions and improved quality of patient care, and least agreement that between-professional rivalries had lessened and communication and trust between professions improved. Conclusions Our longitudinal interventional study of IPC involving multiple activities supporting increased IPC achieved many project-specific goals. However, improvements in attitudes over time were not demonstrated and neutral assessments predominated, highlighting the difficulties faced by studies targeting change at the systems level and over extended periods.

    Full Text Available Objective  To assess the safety and efficiency of robotic minimally invasive surgery and transcatheter interventional occlusion for treatment of adult secundum atrial septal defect (ASD by comparing the early and recent postoperative follow-up results of the two minimally invasive surgery. Methods  Thirty adult patients with secundum ASD, who admitted to the General Hospital of PLA from Jan. 2008 to Dec. 2014 and received treatment of da Vinci Surgical System, were recruited as TEASD-R group, meanwhile, another 30 adult patients who received transcatheter interventional occlusion were recruited under the strict 1:1 criterion as TIASD-O group. The early postoperative complications, in-hospital conditions, recent postoperative follow-up results and the quality of life 30d and 6 months after operation were compared and retrospectively analyzed between the two groups. Results  The success rates of surgery were 100% in the both groups, no early and recent postoperative complications (residual shunt, pericardial effusion, cerebral infarction, peripheral vascular embolism, new arrhythmia, etc. were found in TEASD-R group. While some of corresponding complications existed in TISAD-O group, and the differences were of statistical significance (P<0.05 between the two groups in the incidence of postoperative new arrhythmia, tricuspid incompetence and pulmonary hypertension, as well as in the early size of right atrium and in-hospital time. SF-36 quality of life questionnaire showed that the difference of somatic pain 30d after operation was of statistical significance (P<0.05 between the two groups, but the difference disappeared 6 months after operation. Conclusion  Robotic minimally invasive surgery for adult secundum ASD is feasible, safe and efficacious since no postoperative complications occurred such as tricuspid incompetence and pulmonary hypertension, but the longer operative and inhosptial time are the shortages of the operation.

With a view of developing a "real-world traditional Chinese medicine clinical research paradigm," these clinics explored the mode of constructing research outpatient clinics from the aspects of clinical research, health management, and characteristics diagnosis and treatment.

  18. Physical therapy combined with corticosteroid intervention for systemic lupus erythematosus with central nervous system involvement: a case report. (United States)

    Lee, In-Hee; Ryu, Young Uk


    [Purpose] Systemic lupus erythematosus (SLE) is a chronic, immune-mediated disease, affecting 0.1% of the general population. To date, few studies have investigated the efficacy of physical therapy for SLE patients with CNS involvement. The aim of this study was to report whether the combined use of corticosteroids and physical therapy, consisting of reflex inhibition and functional training, was beneficial to functional recovery. [Subjects and Methods] A 22-year-old male SLE patient with CNS involvement requested physical therapy due to strong spasticity of the trunk and limbs in a bedridden state. Corticosteroid intervention and physical therapy were undertaken for 16 days. [Result] After 16 days of the interventions, the patient demonstrated stabilized and alleviated neurological symptoms and an improved functional level. [Conclusion] The present case indicates that physical therapy combined with corticosteroids might be a possible treatment and rehabilitation method to effectively recover motor function for SLE patients who have strong spasticity due to CNS involvement.

    Beder, Joan; Postiglione, Paul


    For the social worker in the Veterans Health Administration (VA) System, numerous challenges are faced and met while serving the nation's Veterans. As part of the multidisciplinary team, social workers perform a variety of tasks and function in diverse roles. The qualitative survey research reported in this article sought to detail what social workers identified about the impact and rewards of their work and what they saw as the challenges and frustrations. In addition the social workers were asked to clarify their role with the patient and the family. Intervention strategies used in the course of the social workers interaction with the Veterans was also ascertained.

  20. Open Source Clinical NLP - More than Any Single System. (United States)

    Masanz, James; Pakhomov, Serguei V; Xu, Hua; Wu, Stephen T; Chute, Christopher G; Liu, Hongfang


    The number of Natural Language Processing (NLP) tools and systems for processing clinical free-text has grown as interest and processing capability have surged. Unfortunately any two systems typically cannot simply interoperate, even when both are built upon a framework designed to facilitate the creation of pluggable components. We present two ongoing activities promoting open source clinical NLP. The Open Health Natural Language Processing (OHNLP) Consortium was originally founded to foster a collaborative community around clinical NLP, releasing UIMA-based open source software. OHNLP's mission currently includes maintaining a catalog of clinical NLP software and providing interfaces to simplify the interaction of NLP systems. Meanwhile, Apache cTAKES aims to integrate best-of-breed annotators, providing a world-class NLP system for accessing clinical information within free-text. These two activities are complementary. OHNLP promotes open source clinical NLP activities in the research community and Apache cTAKES bridges research to the health information technology (HIT) practice.

  1. The Effect of Educational-Spiritual Intervention on The Burnout of The Parents of School Age Children with Cancer: A Randomized Controlled Clinical Trial (United States)

    Beheshtipour, Nooshin; Nasirpour, Parisa; Yektatalab, Shahrzad; Karimi, Mehran; Zare, Najaf


    Background: Parents of children with cancer experience high levels of stress and discomfort. Religious beliefs are important sources of comfort and support for many cancer patients and their families. The present study aimed to assess the effect of educational-spiritual intervention on burnout of the parents of the children with cancer. Methods: In this randomized clinical trial, 135 parents of children with cancer were randomly assigned into intervention and control groups. Data were collected through SMBQ (Shirom and Melamed Burnout Questionnaire) from both groups, before, immediately after and one month after the intervention. Educational-spiritual programs were held for six weeks, one session every week. The data were analyzed by SPSS using independent t-test, and repeated measure ANOVA. Results: The results showed that the mean burnout score before the intervention in the intervention group was 4.28±0.61 and in the control group it was 4.23±0.50; most of the parents reported moderate to high burnout. But, there was a significant difference between the intervention and control groups immediately after and one month after the intervention (t=10.16, Pburnout score in the intervention group was less than the control group. Results also showed that there was a significant difference between the two groups in terms of parental burnout in three times of measurements (F=58.62, Pburnout of the parents of the children with cancer. Due to high burnout of most of the parents, offering such a program could be beneficial for them. More studies in this regard are recommended.

  2. The effect of system intervention on the cognitive control of preschool children. (United States)

    Modarressi, T


    In response to the high rate of learning problems among socially deprived children, the Baltimore Early School Admission Project set up a system intervention model engaging three points of entry: parents, educators, and mental health workers. The emphasis was on: a) the redefinition of the roles of all participants; b) the school as a self-reliant system, discouraging referrals to outside agencies; c) the development of the children's functioning and adaptive potentials, based on their individual cognitive styles. The program included five public schools. Ninety-one children between the ages of 4 and 5 years were involved. All of these were selected from a hard core socioeconomically deprived population. Eighty-three percent were black and 17 per cent white. Fifteen children were identified as "vulnerable" according to specific criteria provided to the teachers and the parents. Of the vulnerable group, nine children's learning problems were related primarily to emotional and environmental factors, five had perceptual, sensory-motor dysfunction mixed with emotional factors, and one suffered primarily from brain damage. Results indicated that only one of the vulnerable children required referral outside of that provided in the above design. Eleven vulnerable children performed as well as the nonvulnerable group, and three showed a moderate improvement. Furthermore, five children with serious learning problems responded to the systemic intervention as well as they might have with specialized professional help.

  3. Interventions to Support System-level Implementation of Health Promoting Schools: A Scoping Review

    Directory of Open Access Journals (Sweden)

    Jessie-Lee D. McIsaac


    Full Text Available Health promoting schools (HPS is recognized globally as a multifaceted approach that can support health behaviours. There is increasing clarity around factors that influence HPS at a school level but limited synthesized knowledge on the broader system-level elements that may impact local implementation barriers and support uptake of a HPS approach. This study comprised a scoping review to identify, summarise and disseminate the range of research to support the uptake of a HPS approach across school systems. Two reviewers screened and extracted data according to inclusion/exclusion criteria. Relevant studies were identified using a multi-phased approach including searching electronic bibliographic databases of peer reviewed literature, hand-searching reference lists and article recommendations from experts. In total, 41 articles met the inclusion criteria for the review, representing studies across nine international school systems. Overall, studies described policies that provided high-level direction and resources within school jurisdictions to support implementation of a HPS approach. Various multifaceted organizational and professional interventions were identified, including strategies to enable and restructure school environments through education, training, modelling and incentives. A systematic realist review of the literature may be warranted to identify the types of intervention that work best for whom, in what circumstance to create healthier schools and students.

  4. Clinical and Management Requirements for Computerized Mental Health Information Systems


    Levinton, Paula H.; Dunning, Tessa F.E.


    Information requirements of mental health providers are sufficiently different from those of other health care managers to warrant a different approach to the development of management information systems (MIS). Advances in computer technology and increased demands for fiscal accountability have led to developing integrated mental health information systems (MHIS) that support clinical and management requirements.

  6. Toward a world of theranostic medication: Programming biological sentinel systems for therapeutic intervention. (United States)

    Kojima, Ryosuke; Aubel, Dominique; Fussenegger, Martin


    Theranostic systems support diagnostic and therapeutic functions in a single integrated entity and enable precise spatiotemporal control of the generation of therapeutic molecules according to the individual patient's disease state, thereby maximizing the therapeutic outcome and minimizing side effects. These systems can also incorporate reporter systems equipped with a disease-sensing module that can be used to estimate the efficacy of treatment in vivo. Among these reporter systems, biological sentinel systems, such as viruses, bacteria, and mammalian cells, have great potential for use in the development of novel theranostic systems because of their ability to sense a variety of disease markers and secrete various therapeutic molecules. Furthermore, recent advances in biotechnology and synthetic biology have made it possible to treat these biological systems as true programmable entities capable of conducting complex operations, to accurately identify each individual patient's disease state. In this review, we introduce the basic design principles of these rapidly expanding classes of biological sentinel system-based theranostic agents, with a focus on recent advances, and we also discuss potential enabling technologies that can further improve these systems and provide more sophisticated therapeutic interventions in the near future. In addition, we consider the possibility of synergistic use of theranostic agents that use different modalities and discuss the prospects for next-generation theranostic agents.

  7. Improving the implementation of clinical decision support systems. (United States)

    Rüping, Stefan; Anguita, Alberto; Bucur, Anca; Cirstea, Traian Cristian; Jacobs, Björn; Torge, Antje


    Clinical decision support (CDS) systems promise to improve the quality of clinical care by helping physicians to make better, more informed decisions efficiently. However, the design and testing of CDS systems for practical medical use is cumbersome. It has been recognized that this may easily lead to a problematic mismatch between the developers' idea of the system and requirements from clinical practice. In this paper, we will present an approach to reduce the complexity of constructing a CDS system. The approach is based on an ontological annotation of data resources, which improves standardization and the semantic processing of data. This, in turn, allows to use data mining tools to automatically create hypotheses for CDS models, which reduces the manual workload in the creation of a new model. The approach is implemented in the context of EU research project p-medicine. A proof of concept implementation on data from an existing Leukemia study is presented.

The service system applied the concept of modern health management information to implementing informational management for screening,treatment, following up, outcome monitoring, so as to provide a base for promotion of health, diagnosis, treatment as well as scientific research, with the prenatal screening of Down's syndrome as a model. The introduction to informational network during the processes of service has been carried out with regards to its composition, function and application, while introducing the effects of computerized case record individualized in prevention, management and research of Down's syndrome.

  10. Fungal infections of the central nervous system: The clinical syndromes

    Directory of Open Access Journals (Sweden)

    Murthy J.M.K


    Full Text Available Fungal infections of the central nervous system (CNS are being increasingly diagnosed both in immunocompromised and immunocompetent individuals. Sinocranial aspergillosis is more frequently described from countries with temperate climates, more often in otherwise immunocompetent individuals. The clinical syndromes with which fungal infections of the CNS can present are protean and can involve most part of the neuroaxis. Certain clinical syndromes are specific for certain fungal infections. The rhinocerebral form is the most common presenting syndrome with zygomycosis and skull-base syndromes are often the presenting clinical syndromes in patients with sinocranial aspergillosis. Subacute and chronic meningitis in patients with HIV infection is more likely to be due to cryptococcal infection. Early recognition of the clinical syndromes in an appropriate clinical setting is the first step towards achieving total cure in some of these infections.

  11. Screening and brief interventions for hazardous and harmful alcohol use among patients with active tuberculosis attending primary care clinics in South Africa: a cluster randomized controlled trial protocol

    Directory of Open Access Journals (Sweden)

    Naidoo Pamela P


    Full Text Available Abstract Background In 2008 the World Health Organization (WHO reported that South Africa had the highest tuberculosis (TB incidence in the world. This high incidence rate is linked to a number of factors, including HIV co-infection and alcohol use disorders. The diagnosis and treatment package for TB and HIV co-infection is relatively well established in South Africa. However, because alcohol use disorders may present more insidiously, making it difficult to diagnose, those patients with active TB and misusing alcohol are not easily cured from TB. With this in mind, the primary purpose of this cluster randomized controlled trial is to provide screening for alcohol misuse and to test the efficacy of brief interventions in reducing alcohol intake in those patients with active TB found to be misusing alcohol in primary health care clinics in three provinces in South Africa. Methods/Design Within each of the three selected health districts with the highest TB burden in South Africa, 14 primary health care clinics with the highest TB caseloads will be selected. Those agreeing to participate will be stratified according to TB treatment caseload and the type of facility (clinic or community health centre. Within strata from 14 primary care facilities, 7 will be randomly selected into intervention and 7 to control study clinics (42 clinics, 21 intervention clinics and 21 control clinics. At the clinic level systematic sampling will be used to recruit newly diagnosed TB patients. Those consenting will be screened for alcohol misuse using the AUDIT. Patients who screen positive for alcohol misuse over a 6-month period will be given either a brief intervention based on the Information-Motivation-Behavioural Skills (IMB Model or an alcohol use health education leaflet. A total sample size of 520 is expected. Discussion The trial will evaluate the impact of alcohol screening and brief interventions for patients with active TB in primary care settings in

  12. Clinical Effectiveness of Family Therapeutic Interventions Embedded in General Pediatric Primary Care Settings for Parental Mental Health: A Systematic Review and Meta-analysis. (United States)

    Cluxton-Keller, Fallon; Riley, Anne W; Noazin, Sassan; Umoren, Mfon Valencia


    The aim of this systematic review and meta-analysis was to synthesize the available evidence on embedded family therapy interventions in pediatrics and impacts on parental mental health and family functioning outcomes. The Cochrane Collaboration guidelines for systematic reviews and meta-analysis were used for this study. Six electronic databases were searched for randomized controlled trials and cluster randomized trials. The Cochrane Collaboration's Risk of Bias Tool and GRADE system were used to rate the quality of evidence of the included studies. The primary outcomes included parental distress, parental depressive symptoms, and dysfunctional parent-child interaction. Fixed effects models showed statistically significant reductions in parental distress at 6-month and 12-month post-intervention in favor of the intervention group. Family therapy model, intervention level, delivery modality, and dosage moderated intervention impacts on parental distress. Fixed effects models showed statistically significant reductions in parental depressive symptoms and in dysfunctional parent-child interaction in favor of the intervention group. Family therapy interventions can be successfully embedded in general pediatric primary care, and intended outcomes are achieved in this setting. Recommendations for future research and implications for policy development are discussed.

  13. Introduction of Education Systems for Clinical Engineers in Japan

    Japanese clinical engineer (CE) is a significant and unique profession compared with other nations with its dual clinical and technology focus and national licensing. The CE system of licensing was established in May 1987 under the Clinical Engineers Act. CEs are required to complete 3 to 4 years in designated schools and pass a national examination. It is a professional medical position responsible for the operation and maintenance of life-support and non-life-support medical device systems under the direction of physicians. Currently approximately 70 educational institutes - including technical colleges and universities - provide diverse and wide-ranging curricula from engineering to various clinical disciplines to produce CEs. Since clinical practice training is mandatory as a part of institute work, an important approach for CEs is gained by working in hospitals. The comprehensive curricula and the licensing system in Japan together serve to keep the appropriate quantity and quality of CEs. The Japan Association for Clinical Engineers (JACE) was established in February 1990; one of its aims is to support improvement of CEs throughout their careers through various lectures, seminars, on-the-job trainings, workshops, and an annual member meeting. New CEs can now take advantage of video e-learning. For junior CEs, there are seminars for hyperbaric oxygen therapy, blood purification, heart-lung bypass, respiratory therapy, operating room, intensive care unit, arrhythmia and aphaeresis related devices, as well as healthcare technology management (HTM). Also, the institutes provide a leadership seminar alongside this clinical practice training. Besides the licensing process, a proper certification system for CEs is a critical element in the clinical field. This enhances the ability of CEs to engage in more extensive duties and develop specialties, as well as to provide better healthcare. Associated societies provide certification with technology qualifications in

  14. Evaluating statistical and clinical significance of intervention effects in single-case experimental designs: an SPSS method to analyze univariate data. (United States)

    Maric, Marija; de Haan, Else; Hogendoorn, Sanne M; Wolters, Lidewij H; Huizenga, Hilde M


    Single-case experimental designs are useful methods in clinical research practice to investigate individual client progress. Their proliferation might have been hampered by methodological challenges such as the difficulty applying existing statistical procedures. In this article, we describe a data-analytic method to analyze univariate (i.e., one symptom) single-case data using the common package SPSS. This method can help the clinical researcher to investigate whether an intervention works as compared with a baseline period or another intervention type, and to determine whether symptom improvement is clinically significant. First, we describe the statistical method in a conceptual way and show how it can be implemented in SPSS. Simulation studies were performed to determine the number of observation points required per intervention phase. Second, to illustrate this method and its implications, we present a case study of an adolescent with anxiety disorders treated with cognitive-behavioral therapy techniques in an outpatient psychotherapy clinic, whose symptoms were regularly assessed before each session. We provide a description of the data analyses and results of this case study. Finally, we discuss the advantages and shortcomings of the proposed method.

  15. ROV: improving remotely operated vehicle (ROV) intervention capabilities for blowout preventer override systems

    Energy Technology Data Exchange (ETDEWEB)

    Lazar, Stephen [Christopher S. Mancini, Tomball, TX (United States)


    Events during 2010 have focused attention on increased ROV/BOP Intervention capabilities and standardization of BOP/ROV interfaces in the oil and gas offshore industry. Currently no enforced set standards for ROV intervention panels or manifold types for use on BOP Override systems are specified. The industry offers multiple configurations at present. This abstract will discuss the advantages and disadvantages of the various configurations in existence, trending toward suggested industry standards taking shape as requirements in the near term. Standards for the offshore industry or a set specification must be made to increase safety and functionality of BOP control systems. To date, ROV override capabilities have been added to existing engineered BOP systems. BOP designed closing times were not a critical consideration, only that the access was there to allow for ROV override. Increased ROV flow and pressure capabilities: no current minimum flow requirements for Emergency BOP Override pumps are established. Based on stack valving and configuration, a minimum, 7 gpm may be required to shift valving fully to allow BOP operator function. IADC/API minimum requirements may be proposed at 10 gpm at 3000psi. Based on shear pressures exceeding 3000psi, pressures of 5000psi should be considered. Current intervention skids/pump capabilities will be required if ROVs must achieve API 16D BOP minimum closing times. Remote or isolated accumulation for increased intervention capabilities offers possibilities when ANY ROV of opportunity can trigger a function (such as small inspection type ROVs). Increased volumes will be required. This is critical in functioning stack rams with an ROV of opportunity to achieve API 16D closing times. We now understand that higher flows and pressures are required along with standardization of stab types. Current recommendations: API 17H Hi-Flow manifolds should be added to essential ROV overrides. ROV skids will have a minimum requirement of 10gpm

  17. Towards knowledge-based systems in clinical practice: development of an integrated clinical information and knowledge management support system. (United States)

    Kalogeropoulos, Dimitris A; Carson, Ewart R; Collinson, Paul O


    Given that clinicians presented with identical clinical information will act in different ways, there is a need to introduce into routine clinical practice methods and tools to support the scientific homogeneity and accountability of healthcare decisions and actions. The benefits expected from such action include an overall reduction in cost, improved quality of care, patient and public opinion satisfaction. Computer-based medical data processing has yielded methods and tools for managing the task away from the hospital management level and closer to the desired disease and patient management level. To this end, advanced applications of information and disease process modelling technologies have already demonstrated an ability to significantly augment clinical decision making as a by-product. The wide-spread acceptance of evidence-based medicine as the basis of cost-conscious and concurrently quality-wise accountable clinical practice suffices as evidence supporting this claim. Electronic libraries are one-step towards an online status of this key health-care delivery quality control environment. Nonetheless, to date, the underlying information and knowledge management technologies have failed to be integrated into any form of pragmatic or marketable online and real-time clinical decision making tool. One of the main obstacles that needs to be overcome is the development of systems that treat both information and knowledge as clinical objects with same modelling requirements. This paper describes the development of such a system in the form of an intelligent clinical information management system: a system which at the most fundamental level of clinical decision support facilitates both the organised acquisition of clinical information and knowledge and provides a test-bed for the development and evaluation of knowledge-based decision support functions.

    Full Text Available Aims: To determine the effects of percutaneous coronary intervention (PCI on cardiac perfusion, cardiac function, and quality of life in patients with chronic total occlusion (CTO lesion in left anterior descending (LAD coronary artery.Methods and Results: Patients (n=99 with CTO lesion in the LAD coronary artery who had successfully undergone PCI were divided into three groups based on the SPECT/CTCA fusion imaging: (a no severe cardiac perfusion defects (n=9; (b reversible cardiac perfusion defects (n=40; or (c fixed cardiac perfusion defects (n=50. No statistical difference of perfusion abnormality was observed at 6 months and 1 year after PCI in group (a. In group (b, SPECT/CTCA fusion imaging demonstrated that cardiac perfusion abnormality was significantly decreased 6 month and 1 year after PCI. Left ventricular ejection fraction (LVEF increased significantly at 6 months and 1 year follow up. Quality of life improved at 6 months and 1 year after PCI procedure. Moreover, patients in group (c also benefited from PCI therapy: a decrease in cardiac perfusion abnormality, an increase in LVEF, and an improvement in quality of life. PCI of coronary arteries in addition to LAD did not significantly affect cardiac function and quality of life improvement in each group.Conclusions: PCI exerts functional and clinical benefits in patients with CTO lesion in LAD coronary artery, particularly in patients with reversible cardiac perfusion defects. SPECT/CTCA fusion imaging may serve as a useful tool to evaluate the outcomes of patients with CTO lesion in LAD coronary artery.

  20. Evidence-based interventional pain medicine according to clinical diagnoses. 17. Herpes zoster and post-herpetic neuralgia. (United States)

    van Wijck, Albert J M; Wallace, Mark; Mekhail, Nagy; van Kleef, Maarten


    Herpes zoster infection is caused by a reactivation of the latent varicella zoster virus that causes chicken pox. It appears predominantly in older adults whose immunity for the virus has waned. The natural course of the disease is usually favorable, and the symptoms disappear spontaneously within a few weeks. Some patients, however, have prolonged pain: post-herpetic neuralgia. The diagnosis of acute zoster infection is made on the clinical signs including the appearance of rash. Post-herpetic neuralgia is described as sharp, burning, aching, or shooting constantly present in the dermatome that corresponds with the earlier rash. The objectives of treating herpes zoster are: (1) acute pain reduction; (2) promotion of recovery of epidermal defects and prevention of secondary infections; and (3) reduction or prevention of post-herpetic neuralgia. The objective of the treatment of post-herpetic neuralgia is primarily pain alleviation and improvement of the quality of life. Early treatment of the infection and the pain is believed to reduce the risk for post-herpetic neuralgia. This persistent pain syndrome is difficult to treat. Antiepileptic drugs and tricyclic antidepressants are the first choice. Interventional treatments, such as epidural injections of corticosteroids and local anesthetic drugs, have an effect on the acute pain but are of limited use in preventing post-herpetic neuralgia. When conservative treatment fails in providing satisfactory relief of post-herpetic neuralgia, a sympathetic block may be considered (2 C+); if this treatment provides unsatisfactory results, spinal cord stimulation may be considered, in a study context (2 C+).

    Full Text Available Objective To assess impact of selective thrombus aspiration (TA during primary percutaneous coronary intervention (pPCI on long-term prognosis in patients with ST-segment elevation myocardial infarction (STEMI. Methods  Between Jan. 2008 and Jan. 2014, a total of 2357 STEMI patients [429 in thrombus aspiration (TA group and 1928 in routine percutaneous coronsry intorventim (PCI group (control group] were eligible for the study criteria and candidates for pPCI were enrolled in this study. The reflow of the involved vessel in pPCI procedure, stent thrombosis and major adverse cardiac events (MACE were comparatively analyzed in the two groups during hospital stay and 12-month follow-up period. Results Although the success rate of TA procedure was significantly lower in TA group compared with that in control group (P<0.001, both the TIMI flow grade ≥2 after TA procedure and stent implantation occurred more frequently in TA group than in control group (P<0.05. The rates of MACE and stent thrombosis showed no difference between two groups during in-hospital and 12-month follow-up period (P>0.05. But the rates of total MACE and target vessel revascularization were significantly higher in control group than in TA group (P=0.04. Conclusion Selective TA procedure before primary PCI could improve final myocardial reperfusion, reduce the incidence of MACE and improve the 1-year clinical result for STEMI patients.

    In interventional radiology adjunctive medical therapy can increase patient's comfort, and should further reduce the risks of the procedures. In order to fulfill the responsibility of the interventionist to the patients and to increase the success rate of the interventions, a profound knowledge of certain drugs is indispensable. This includes, for example, sedatives, analgesics, cardiovascular drugs and agents to prevent infections, thromboembolic complications or restenoses. Moreover, a good monitoring system during complex procedures will increase the safety of radiological interventions. These topics and several more are presented in this book. (orig.). 32 figs.

    Background:The impact of body mass index (BMI) on the clinical outcomes after percutaneous coronary intervention (PCI) in patients ≥75 years old remained unclear.Methods:A total of 1098 elderly patients undergoing PCI with stent implantation were recruited.Patients were divided into four groups by the value of BMI:Underweight (<20.0 kg/m2),normal weight (20.0-24.9 kg/m2),overweight (25.0-29.9 kg/m2) and obese (≥30.0 kg/m2).Major clinical outcomes after PCI were compared between the groups.The primary endpoint was defined as in-hospital major adverse cardiovascular events (MACEs),which included death,myocardial infarction (MI) and target vessel revascularization.The secondary endpoint was defined as 1 year death.Logistic regression analysis was performed to adjust for the potential confounders.Results:Totally,1077 elderly patients with available BMIs were included in the analysis.Patients of underweight,normal weight,overweight and obese accounted for 5.6%,45.4%,41.5% and 7.5% of the population,respectively.Underweight patients were more likely to attract ST-segment elevation MI,and get accompanied with anemia or renal dysfunction.Meanwhile,they were less likely to achieve thrombolysis in MI 3 grade flow after PCI,and receive beta-blocker,angiotensin converting enzyme inhibitor or angiotensin receptor blocker after discharge.In underweight,normal weight,overweight and obese patients,in-hospital MACE were 1.7%,2.7%,3.8%,and 3.7% respectively (P =0.68),and 1 year mortality rates were 5.0%,3.9%,5.1% and 3.7% (P =0.80),without significant difference between the groups.Multivariate regression analysis showed that the value of BMI was not associated with in-hospital MACE in patients at 75 years old.Conclusions:The BMI "obese paradox" was not found in patients ≥75 years old.It was suggested that BMI may not be a sensitive predictor of adverse cardiovascular events in elderly patients.

  4. SICAR: geographic information system for the documentation of restoration analyses and intervention (United States)

    Baracchini, Clara; Lanari, Paolo; Scopigno, Roberto; Tecchia, Franco; Vecchi, Andrea


    SICAR is an internet-based system for the management of the information gathered during restoration analysis and intervention (alphanumeric and raster data), which is mapped and geo-referenced to 2D or 3D models. Joining the skills of a set of multidisciplinary partners, an integrated and innovative system will be developed, to permit to link to an accurate 2D or 3D model of the monument under restoration all the data gathered during the restoration analysis and intervention [raster images, document in TXT format, hypertext (HTML) or semi-structured text (XML)]. As far concerns semi-structured texts, a software module will automatically process documents, extracting their structure. SICAR will be developed to be completely accessible via web, for data entry and displaying, and will be suitable to wireless and intranet connection (GPRS, Bluetooth, etc.), in order to document the status of the objects to be restored, in restoration sites or laboratories. In this way data will be accessible even with low-speed connection.

  5. Toll-like Receptors in Systemic Lupus Erythematosus Prospects for Therapeutic Intervention (United States)

    Kim, Wan-Uk; Sreih, Antoine; Bucala, Richard


    Recent experimental and clinical studies have placed new emphasis on the role of the innate immune system in SLE. Nucleic acid-containing immune complexes activate the innate response by engaging specific Toll-like receptors (TLRs) and promote the generation of autoantibodies. Pharmacologic modulation of TLR-directed pathways may offer new therapeutic approaches for the treatment of SLE. PMID:18722558

  7. Exercise and Motor Training in People with Parkinson's Disease: A Systematic Review of Participant Characteristics, Intervention Delivery, Retention Rates, Adherence, and Adverse Events in Clinical Trials

    Directory of Open Access Journals (Sweden)

    Natalie E. Allen


    Full Text Available There is research evidence that exercise and motor training are beneficial for people with Parkinson's disease (PD, and clinicians seek to implement optimal programs. This paper summarizes important factors about the nature and reporting of randomized controlled trials of exercise and/or motor training for people with PD which are likely to influence the translation of research into clinical practice. Searches identified 53 relevant trials with 90 interventions conducted for an average duration of 8.3 (SD 4.2 weeks. Most interventions were fully supervised (74% and conducted at a facility (79%. Retention rates were high with 69% of interventions retaining ≥85% of their participants; however adherence was infrequently reported, and 72% of trials did not report adverse events. Overall, the labor-intensive nature of most interventions tested in these trials and the sparse reporting of adherence and adverse events are likely to pose difficulties for therapists attempting to balance benefits and costs when selecting protocols that translate to sustainable clinical practice for people with PD.

  8. Incorporating Systems Science Principles into the Development of Obesity Prevention Interventions: Principles, Benefits, and Challenges. (United States)

    Gittelsohn, Joel; Mui, Yeeli; Adam, Atif; Lin, Sen; Kharmats, Anna; Igusa, Takeru; Lee, Bruce Y


    Systems modeling represents an innovative approach for addressing the obesity epidemic at the community level. We developed an agent-based model of the Baltimore City food environment that permits us to assess the relative impact of different programs and policies, alone and in combination, and potential unexpected consequences. Based on this experience, and a review of literature, we have identified a set of principles, potential benefits, and challenges. Some of the key principles include the importance of early and multilevel engagement with the community prior to initiating model development and continued engagement and testing with community stakeholders. Important benefits include improving community stakeholder understanding of the system, testing of interventions before implementation, and identification of unexpected consequences. Challenges in these models include deciding on the most important, yet parsimonious factors to consider, how to model food source and food selection behavior in a realistic yet transferable manner, and identifying the appropriate outcomes and limitations of the model.

  9. Metadata registry and management system based on ISO 11179 for Cancer Clinical Trials Information System. (United States)

    Park, Yu Rang; Kim, Ju Han


    Standardized management of data elements (DEs) for Case Report Form (CRF) is crucial in Clinical Trials Information System (CTIS). Traditional CTISs utilize organization-specific definitions and storage methods for Des and CRFs. We developed metadata-based DE management system for clinical trials, Clinical and Histopathological Metadata Registry (CHMR), using international standard for metadata registry (ISO 11179) for the management of cancer clinical trials information. CHMR was evaluated in cancer clinical trials with 1625 DEs extracted from the College of American Pathologists Cancer Protocols for 20 major cancers.

  11. Methodology of integration of a clinical data warehouse with a clinical information system: the HEGP case. (United States)

    Zapletal, Eric; Rodon, Nicolas; Grabar, Natalia; Degoulet, Patrice


    Clinical Data Warehouses (CDW) can complement current Clinical Information Systems (CIS) with functions that are not easily implemented by traditional operational database systems. Here, we describe the design and deployment strategy used at the Pompidou University Hospital in southwest Paris. Four realms are described: technological realm, data realm, restitution realm, and administration realm. The corresponding UML use cases and the mapping rules from the shared integrated electronic health records to the five axes of the i2b2 CDW star model are presented. Priority is given to the anonymization and security principles used for the 1.2 million patient records currently stored in the CDW. Exploitation of a CDW by clinicians and investigators can facilitate clinical research, quality evaluations and outcome studies. These indirect benefits are among the reasons for the continuous use of an integrated CIS.

  12. [Costs analysis system; its location within a program for food, nutrition and metabolic intervention]. (United States)

    Fernández Hernández, Ileana Sonia; Santana Porbén, Sergio


    Every medical surgical action implies costs. Costs of medical provisions should be translated into tangible, and thus, measurable, benefits for the health status of the patient. Nutritional support therapies might increase the costs of medical provisions, but it is expected their implementation to result in lower morbidity and mortality rates as well as shortening of hospital stay, all of them leading to important savings. It is then required the assimilation of tools for costs analysis for a better management of nutritional support therapies. A proposal for the design of a hospital system (regarded anywhere in this text as SHACOST) for the analysis of the costs of interventions conducted in a patient in accordance with the guidelines included in the Metabolic, Nutrient and Food Intervention Program (referred everywhere for its Spanish acronym PRINUMA) is presented in this article. Hence, strategies are described to estimate the costs of a specified intervention. In addition, a primer on cost-effectiveness (ACE) and incremental cost-effectiveness (ACEI) analyses is shown relying on examples taken from the authors's experience in the provision of nutritional care to patients electively operated for a colorectal cancer. Finally, costs of surgical treatment of a mandibular tumor are described, followed by a discussion on how a better impact of the adopted surgical action could be achieved without considerable increases in total costs should a perioperatory nutritional support program be included. Implementation of SHACOST can provide the medical care teams with accounting tools required to assess the effectiveness of hospital nutritional support schemes, decide whether to acquire and introduce new technologies, and measure the impact of the performance of hospital forms for provision of nutritional care upon health management and perceived quality of life of the patient and their relatives.

  13. The "close-in" or ultra high-risk model: a safe and effective strategy for research and clinical intervention in prepsychotic mental disorder. (United States)

    McGorry, Patrick D; Yung, Alison R; Phillips, Lisa J


    The development of a new frontier for research and early intervention in psychotic disorders is highly dependent on the construction of synergistic clinical infrastructures. This has catalyzed great progress in the recognition, enhanced treatment, and study of first episode psychosis, and the task is even more challenging when the boundaries are extended to include the earliest clinical phase of illness, the prodromal or prepsychotic phase. This article describes the conceptual and practical building blocks for the construction of service models for intervention in the postonset clinical phase prior to the attainment of current diagnostic thresholds. This is best regarded as indicated prevention, a form of very early secondary prevention, which involves a blend of immediate clinical care combined with research-oriented preventive intervention. The experience of the Personal Assessment and Crisis Evaluation (PACE) Clinic in Melbourne across several stages of growth is described and contrasted with that of several emerging centers in Europe and North America. The progress to date, the lessons learned, and the unresolved challenges and opportunities are detailed. It is concluded that service models can be developed that are acceptable and helpful to young people and their families, and that create a unique environment for the study of the transition to frank psychotic disorder. The ultimate clinical utility and general safety of this approach and the range of effective treatments remain unclear, and will be determined by more extensive research. Such research must be conducted in a logical and rigorous manner with the best designs possible, sensitive to input from consumers and caregivers and to ethical considerations.

  14. A networked modular hardware and software system for MRI-guided robotic prostate interventions (United States)

    Su, Hao; Shang, Weijian; Harrington, Kevin; Camilo, Alex; Cole, Gregory; Tokuda, Junichi; Hata, Nobuhiko; Tempany, Clare; Fischer, Gregory S.


    Magnetic resonance imaging (MRI) provides high resolution multi-parametric imaging, large soft tissue contrast, and interactive image updates making it an ideal modality for diagnosing prostate cancer and guiding surgical tools. Despite a substantial armamentarium of apparatuses and systems has been developed to assist surgical diagnosis and therapy for MRI-guided procedures over last decade, the unified method to develop high fidelity robotic systems in terms of accuracy, dynamic performance, size, robustness and modularity, to work inside close-bore MRI scanner still remains a challenge. In this work, we develop and evaluate an integrated modular hardware and software system to support the surgical workflow of intra-operative MRI, with percutaneous prostate intervention as an illustrative case. Specifically, the distinct apparatuses and methods include: 1) a robot controller system for precision closed loop control of piezoelectric motors, 2) a robot control interface software that connects the 3D Slicer navigation software and the robot controller to exchange robot commands and coordinates using the OpenIGTLink open network communication protocol, and 3) MRI scan plane alignment to the planned path and imaging of the needle as it is inserted into the target location. A preliminary experiment with ex-vivo phantom validates the system workflow, MRI-compatibility and shows that the robotic system has a better than 0.01mm positioning accuracy.

  15. Interventions to increase access to STI services: A study of England?s `High Impact Changes? across three central London clinics


    Menon-Johansson, Anatole S; Cohen, Charlotte; Jones, Rachael; Nwokolo, Nneka; McOwan, Alan; Barton, Simon E.; Mandalia, Sundhiya; Sullivan, Ann K.


    Abstract Background Increasing access to sexual health services is a key objective for the Department of Health (DH) in England and Wales. In 2006 the DH published ten high impact changes (HICs) designed to enhance 48-hour access to genitourinary medicine services. However, there is limited evidence on the effectiveness of the proposed interventions. We therefore evaluated the implementation of five HICs in three sexual health clinics over four years. These HICs included a t...

    Pfefferbaum, Betty; North, Carol S


    Several decades of research have informed our knowledge of children's reactions to disasters and the factors that influence their reactions. This article describes the system of care for child disaster mental health services using population risk to determine needed services and a stepped care approach built on assessment and monitoring to advance children to appropriate services. To assess the evidence base for disaster interventions, recent reviews of numerous child disaster mental health interventions are summarized.

  18. Laboratory automation in clinical bacteriology: what system to choose? (United States)

    Croxatto, A; Prod'hom, G; Faverjon, F; Rochais, Y; Greub, G


    Automation was introduced many years ago in several diagnostic disciplines such as chemistry, haematology and molecular biology. The first laboratory automation system for clinical bacteriology was released in 2006, and it rapidly proved its value by increasing productivity, allowing a continuous increase in sample volumes despite limited budgets and personnel shortages. Today, two major manufacturers, BD Kiestra and Copan, are commercializing partial or complete laboratory automation systems for bacteriology. The laboratory automation systems are rapidly evolving to provide improved hardware and software solutions to optimize laboratory efficiency. However, the complex parameters of the laboratory and automation systems must be considered to determine the best system for each given laboratory. We address several topics on laboratory automation that may help clinical bacteriologists to understand the particularities and operative modalities of the different systems. We present (a) a comparison of the engineering and technical features of the various elements composing the two different automated systems currently available, (b) the system workflows of partial and complete laboratory automation, which define the basis for laboratory reorganization required to optimize system efficiency, (c) the concept of digital imaging and telebacteriology, (d) the connectivity of laboratory automation to the laboratory information system, (e) the general advantages and disadvantages as well as the expected impacts provided by laboratory automation and (f) the laboratory data required to conduct a workflow assessment to determine the best configuration of an automated system for the laboratory activities and specificities.

  19. NOTE: MRI-guided robotic system for transperineal prostate interventions: proof of principle (United States)

    van den Bosch, Michiel R.; Moman, Maaike R.; van Vulpen, Marco; Battermann, Jan J.; Duiveman, Ed; van Schelven, Leonard J.; de Leeuw, Hendrik; Lagendijk, Jan J. W.; Moerland, Marinus A.


    In this study, we demonstrate the proof of principle of the University Medical Center Utrecht (UMCU) robot dedicated to magnetic resonance imaging (MRI)-guided interventions in patients. The UMCU robot consists of polymers and non-ferromagnetic materials. For transperineal prostate interventions, it can be placed between the patient's legs inside a closed bore 1.5T MR scanner. The robot can manually be translated and rotated resulting in five degrees of freedom. It contains a pneumatically driven tapping device to automatically insert a needle stepwise into the prostate using a controller unit outside the scanning room. To define the target positions and to verify the needle insertion point and the needle trajectory, a high-resolution 3D balanced steady state free precession (bSSFP) scan that provides a T2/T1-weighted contrast is acquired. During the needle insertion fast 2D bSSFP images are generated to track the needle on-line. When the target position is reached, the radiation oncologist manually places a fiducial gold marker (small seed) at this location. In total two needle trajectories are used to place all markers. Afterwards, a high-resolution 3D bSSFP scan is acquired to visualize the fiducial gold markers. Four fiducial gold markers were placed transperineally into the prostate of a patient with a clinical stage T3 prostate cancer. In the generated scans, it was possible to discriminate the patient's anatomy, the needle and the markers. All markers were delivered inside the prostate. The procedure time was 1.5 h. This study proves that MRI-guided needle placement and seed delivery in the prostate with the UMCU robot are feasible.

  20. CliniProteus: A flexible clinical trials information management system (United States)

    Mathura, Venkatarajan S; Rangareddy, Mahendiranath; Gupta, Pankaj; Mullan, Michael


    Clinical trials involve multi-site heterogeneous data generation with complex data input-formats and forms. The data should be captured and queried in an integrated fashion to facilitate further analysis. Electronic case-report forms (eCRF) are gaining popularity since it allows capture of clinical information in a rapid manner. We have designed and developed an XML based flexible clinical trials data management framework in .NET environment that can be used for efficient design and deployment of eCRFs to efficiently collate data and analyze information from multi-site clinical trials. The main components of our system include an XML form designer, a Patient registration eForm, reusable eForms, multiple-visit data capture and consolidated reports. A unique id is used for tracking the trial, site of occurrence, the patient and the year of recruitment. Availability PMID:21670796

  1. Bluetooth Roaming for Sensor Network System in Clinical Environment. (United States)

    Kuroda, Tomohiro; Noma, Haruo; Takase, Kazuhiko; Sasaki, Shigeto; Takemura, Tadamasa


    A sensor network is key infrastructure for advancing a hospital information system (HIS). The authors proposed a method to provide roaming functionality for Bluetooth to realize a Bluetooth-based sensor network, which is suitable to connect clinical devices. The proposed method makes the average response time of a Bluetooth connection less than one second by making the master device repeat the inquiry process endlessly and modifies parameters of the inquiry process. The authors applied the developed sensor network for daily clinical activities in an university hospital, and confirmed the stabilitya and effectiveness of the sensor network. As Bluetooth becomes a quite common wireless interface for medical devices, the proposed protocol that realizes Bluetooth-based sensor network enables HIS to equip various clinical devices and, consequently, lets information and communication technologies advance clinical services.

  2. Outcomes of Health System Structures, Highly Pertinent Clinical Information, Idea Stimulators, Clinical Reviews, and Prediction Tools: JABFM Exemplified. (United States)

    Bowman, Marjorie A; Neale, Anne Victoria; Seehusen, Dean A


    This issue exemplifies the types of articles that JABFM publishes to advance family medicine. We have articles on the implications of health system organizational structures. Three of these are international articles at the level of the national health system (1 from China) and systematic local health interventions (1 from Canada and 1 from Netherlands). Inside the United States, where there are more family physicians, there is less obesity, and designation as a Patient Centered Medical Home is related to increased rates of colorectal cancer screening. Review articles on common clinical topics discuss treatments that are changing (acne in pregnancy) or lack consensus (distal radial fractures). We have articles on making life easier in the office, such as for predicting Vitamin D levels, osteoporosis, and pre-diabetes in normal weight adults. There are articles to raise awareness of the "newest" testing or treatments, that is, auditory brainstem implants. "Reminder" articles highlight known entities that need to be reinforced to prevent over-/underdiagnosis or treatment, for example, "cotton fever." Another article discusses the increased risk for postoperative complications with sleep apnea. We also provide "thought" pieces, in this case about the terminology we are using to extend our concept of patient-centered medical homes.

  4. [Efficiency, risks, and advantages of using robotic support systems in interventional medicine]. (United States)

    Feussner, H; Can, S; Fiolka, A; Schneider, A; Wilhelm, D


    During the past decade, robotic systems were evaluated for the first time in practically all surgical disciplines. With only a few exceptions (radical prostatectomy), mechatronic systems did not achieve a breakthrough in any field of application. Second generation robotic devices with better integration of complementary technologies (preoperative therapy planning, intraoperative diagnostic work-up, navigation, etc.) and augmented functionality are now ready to be introduced into clinical practice. It is hoped that the specific advantages of robotics will result in increased use compared to previous systems. Robotics is a key technology if new surgical strategies ("scarless surgery") are to succeed.

  5. Clinical decision support for perioperative information management systems. (United States)

    Wanderer, Jonathan P; Ehrenfeld, Jesse M


    Clinical decision support (CDS) systems are being used to optimize the increasingly complex care that our health care system delivers. These systems have become increasingly important in the delivery of perioperative care for patients undergoing cardiac, thoracic, and vascular procedures. The adoption of perioperative information management systems (PIMS) has allowed these technologies to enter the operating room and support the clinical work flow of anesthesiologists and operational processes. Constructing effective CDS systems necessitates an understanding of operative work flow and technical considerations as well as achieving integration with existing information systems. In this review, we describe published examples of CDS for PIMS, including support for cardiopulmonary bypass separation physiological alarms, β-blocker guideline adherence, enhanced revenue capture for arterial line placement, and detection of hemodynamic monitoring gaps. Although these and other areas are amenable to CDS systems, the challenges of latency and data reliability represent fundamental limitations on the potential application of these tools to specific types of clinical issues. Ultimately, we expect that CDS will remain an important tool in our efforts to optimize the quality of care delivered.

  6. [Knowledge management system for laboratory work and clinical decision support]. (United States)

    Inada, Masanori; Sato, Mayumi; Yoneyama, Akiko


    This paper discusses a knowledge management system for clinical laboratories. In the clinical laboratory of Toranomon Hospital, we receive about 20 questions relevant to laboratory tests per day from medical doctors or co-medical staff. These questions mostly involve the essence to appropriately accomplish laboratory tests. We have to answer them carefully and suitably because an incorrect answer may cause a medical accident. Up to now, no method has been in place to achieve a rapid response and standardized answers. For this reason, the laboratory staff have responded to various questions based on their individual knowledge. We began to develop a knowledge management system to promote the knowledge of staff working for the laboratory. This system is a type of knowledge base for assisting the work, such as inquiry management, laboratory consultation, process management, and clinical support. It consists of several functions: guiding laboratory test information, managing inquiries from medical staff, reporting results of patient consultation, distributing laboratory staffs notes, and recording guidelines for laboratory medicine. The laboratory test information guide has 2,000 records of medical test information registered in the database with flexible retrieval. The inquiry management tool provides a methos to record all questions, answer easily, and retrieve cases. It helps staff to respond appropriately in a short period of time. The consulting report system treats patients' claims regarding medical tests. The laboratory staffs notes enter a file management system so they can be accessed to aid in clinical support. Knowledge sharing using this function can achieve the transition from individual to organizational learning. Storing guidelines for laboratory medicine will support EBM. Finally, it is expected that this system will support intellectual activity concerning laboratory work and contribute to the practice of knowledge management for clinical work support.

  7. Systems for physical health care for mental health patients in the community: different approaches to improve patient care and safety in an Early Intervention in Psychosis Service (United States)

    Mouko, Josie; Sullivan, Rebecca


    Patients with mental illnesses have a high rate of physical comorbidity, and specifically, those with psychosis are at an increased risk of cardiometabolic disease and shortened lifespans, due to medication, lifestyle and illness factors. There are recognised challenges with physical health care in this group. At baseline, no patients on the Bath and North East Somerset Early Intervention in Psychosis caseload had a fully completed physical health assessment. Our aim was to offer a physical health check, blood tests, and ECG for all patients, trialling four phases of interventions. The four phases were (1) increased awareness, education and data collection tools; (2) mobile physical health clinics; (3) letters sent to patients and GPs to request health checks be conducted, (4) a combination of the above approaches, as well as regular caseload reviews and prompts to professionals. At the time of our study (2015-16), many of the above parameters were also incentivised nationally by Commissioning for Quality and Innovation (CQUIN) payments. The mobile physical health clinic offered patient choice of home visits or clinic checks, to increase engagement and provide flexible care. The most successful approach overall was the combination approach, resulting in 48% of all patients having fully completed physical health checks, bloods and ECGs. The mobile clinic resulted in physical health checks completion rates of 60%, and blood tests in 65-70%. 92% of patients undertook ECG's, following letter requests to GPs and patients. Combining mobile physical health clinics, GP letters, financial incentives and managerial engagement produced much improved results, but was very time consuming, and in our case was inefficient due to using multiple professionals. We recommend embedding such approaches within the team, using sustainable systems, and would encourage teams to trial dedicated trained clinicians to establish sustainable systems to improve the physical health care of this

  12. Designing clinically useful systems: examples from medicine and dentistry. (United States)

    Koch, S


    Despite promising results in medical informatics research and the development of a large number of different systems, few systems get beyond a prototype state and are really used in practice. Among other factors, the lack of explicit user focus is one main reason. The research projects presented in this paper follow a user-centered system development approach based on extensive work analyses in interdisciplinary working groups, taking into account human cognitive performance. Different medical and health-care specialists, together with researchers in human-computer interaction and medical informatics, specify future clinical work scenarios. Special focus is put on analysis and design of the information and communication flow and on exploration of intuitive visualization and interaction techniques for clinical information. Adequate choice of the technical access device is made depending on the user's work situation. It is the purpose of this paper to apply this method in two different research projects and thereby to show its potential for designing clinically useful systems that do support and not hamper clinical work. These research projects cover IT support for chairside work in dentistry ( and ICT support for home health care of elderly citizens (

  17. Paediatric early warning systems for detecting and responding to clinical deterioration in children: a systematic review (United States)

    Lambert, Veronica; Matthews, Anne; MacDonell, Rachel; Fitzsimons, John


    Objective To systematically review the available evidence on paediatric early warning systems (PEWS) for use in acute paediatric healthcare settings for the detection of, and timely response to, clinical deterioration in children. Method The electronic databases PubMed, MEDLINE, CINAHL, EMBASE and Cochrane were searched systematically from inception up to August 2016. Eligible studies had to refer to PEWS, inclusive of rapid response systems and teams. Outcomes had to be specific to the identification of and/or response to clinical deterioration in children (including neonates) in paediatric hospital settings (including emergency departments). 2 review authors independently completed the screening and selection process, the quality appraisal of the retrieved evidence and data extraction; with a third reviewer resolving any discrepancies, as required. Results were narratively synthesised. Results From a total screening of 2742 papers, 90 papers, of varied designs, were identified as eligible for inclusion in the review. Findings revealed that PEWS are extensively used internationally in paediatric inpatient hospital settings. However, robust empirical evidence on which PEWS is most effective was limited. The studies examined did however highlight some evidence of positive directional trends in improving clinical and process-based outcomes for clinically deteriorating children. Favourable outcomes were also identified for enhanced multidisciplinary team work, communication and confidence in recognising, reporting and making decisions about child clinical deterioration. Conclusions Despite many studies reporting on the complexity and multifaceted nature of PEWS, no evidence was sourced which examined PEWS as a complex healthcare intervention. Future research needs to investigate PEWS as a complex multifaceted sociotechnical system that is embedded in a wider safety culture influenced by many organisational and human factors. PEWS should be embraced as a part of a

    Abbott, M; Bellringer, M; Vandal, A C; Hodgins, D C; Battersby, M; Rodda, S N


    Introduction The primary purpose of this study is to evaluate the relative effectiveness of 2 of the best developed and most promising forms of therapy for problem gambling, namely face-to-face motivational interviewing (MI) combined with a self-instruction booklet (W) and follow-up telephone booster sessions (B; MI+W+B) and face-to-face cognitive–behavioural therapy (CBT). Methods and analysis This project is a single-blind pragmatic randomised clinical trial of 2 interventions, with and without the addition of relapse-prevention text messages. Trial assessments take place pretreatment, at 3 and 12 months. A total of 300 participants will be recruited through a community treatment agency that provides services across New Zealand and randomised to up to 10 face-to-face sessions of CBT or 1 face-to-face session of MI+W+up to 5 B. Participants will also be randomised to 9 months of postcare text messaging. Eligibility criteria include a self-perception of having a current gambling problem and a willingness to participate in all components of the study (eg, read workbook). The statistical analysis will use an intent-to-treat approach. Primary outcome measures are days spent gambling and amount of money spent per day gambling in the prior month. Secondary outcome measures include problem gambling severity, gambling urges, gambling cognitions, mood, alcohol, drug use, tobacco, psychological distress, quality of life, health status and direct and indirect costs associated with treatment. Ethics and dissemination The research methods to be used in this study have been approved by the Ministry of Health, Health and Disability Ethics Committees (HDEC) 15/CEN/99. The investigators will provide annual reports to the HDEC and report any adverse events to this committee. Amendments will also be submitted to this committee. The results of this trial will be submitted for publication in peer-reviewed journals and as a report to the funding body. Additionally, the results

    Pfund, A; Wendland, G; Baer, F; Lauterbach, K; Höpp, H W


    The reduction of acute complications and late restenosis compared to conventional PTCA has led to a rapid increase in stent implantation as initial treatment for coronary stenosis. As a result, in-stent restenosis has become an important clinical and economical problem, especially the diffuse form, which is much more likely to reappear. In order to compare the consequences of initial stenting and initial angioplasty, we developed an analytic model, considering the differences between diffuse and focal in-stent restenosis. The simulation based on the optimized therapeutic proceeding following an elective 1-vessel revascularization of a 60-year-old patient, dealing with probabilities for acute complications and late restenosis taken from the literature and in-hospital costs obtained from 200 elective interventions. In the stent group 71.0% of patients were free of any target lesion-related event, compared to 60.2% in the PTCA group. Catheter reintervention was necessary for 32.1% of the patients initially treated with angioplasty and for 17.6% of the initially stented patients, whereas 7.7% of the stent patients had to undergo elective bypass surgery as final treatment compared to 2.8% in the PTCA arm. Long-term medical costs for initial stenting (6,237 Euros) were 14% higher than for conventional PTCA (5,345 Euros). Taking also into consideration the indirect costs (loss of productivity) for a collective with an employment rate of 50%, the difference between stent implantation (9,067 Euros) and angioplasty (8,581 Euros) is smaller. Initial treatment of coronary stenosis by stent implantation decreases the rate of repeat revascularization compared to initial PTCA, but there is a greater likelihood that elective bypass surgery will become necessary. This difference in following treatment is related to the occurrence of diffuse in-stent restenosis. When calculating the long-term costs stenting still appeared to be more expensive than PTCAA because the savings in

    Full Text Available Introduction: Studies have indicated a global high prevalence of hospital malnutrition on admission and during hospitalization. Clinical Nutritional Risk Screen (CNRS is a way to identify malnutrition and manage nutritional interventions. Several traditional and non-computer based tools have been suggested for screening nutritional risk levels. The present study was an attempt to employ a computer based fuzzy model decision support system as a nutrition-screening tool for inpatients. Method: This is an applied modeling study. The system architecture was designed based on the fuzzy logic model including input data, inference engine, and output. A clinical nutritionist entered nineteen input variables using a windows-based graphical user interface. The inference engine was involved with knowledge obtained from literature and the construction of ‘IF-THEN’ rules. The output of the system was stratification of patients into four risk levels from ‘No’ to ‘High’ where a number was also allocated to them as a nutritional risk grade. All patients (121 people admitted during implementing the system participated in testing the model. The classification tests were used to measure the CNRS fuzzy model performance. IBM SPSS version 21 was utilized as a tool for data analysis with α = 0.05 as a significance level. Results: Results showed that sensitivity, specificity, accuracy, and precision of the fuzzy model performance were 91.67% (±4.92, 76% (±7.6, 88.43% (±5.7, and 93.62% (±4.32, respectively. Instant performance on admission and very low probability of mistake in predicting malnutrition risk level may justify using the model in hospitals. Conclusion: To conclude, the fuzzy model-screening tool is based on multiple nutritional risk factors, having the capability of classifying inpatients into several nutritional risk levels and identifying the level of required nutritional intervention.

  2. Cross-system evaluation of clinical trial search engines. (United States)

    Jiang, Silis Y; Weng, Chunhua


    Clinical trials are fundamental to the advancement of medicine but constantly face recruitment difficulties. Various clinical trial search engines have been designed to help health consumers identify trials for which they may be eligible. Unfortunately, knowledge of the usefulness and usability of their designs remains scarce. In this study, we used mixed methods, including time-motion analysis, think-aloud protocol, and survey, to evaluate five popular clinical trial search engines with 11 users. Differences in user preferences and time spent on each system were observed and correlated with user characteristics. In general, searching for applicable trials using these systems is a cognitively demanding task. Our results show that user perceptions of these systems are multifactorial. The survey indicated eTACTS being the generally preferred system, but this finding did not persist among all mixed methods. This study confirms the value of mixed-methods for a comprehensive system evaluation. Future system designers must be aware that different users groups expect different functionalities.

    We have been using an X-ray angiography system that incorporates a flat panel detector (FPD) since December 2001. This system is equipped with the scintillator-type FPD PaxScan 4030A from Varian Medical Systems, and for objective comparison of the image intensifier (I.I.) and FPD, the system is constructed so that these detectors can be used alternatively. Using this system and other X-ray angiography systems, visual studies have been conducted on the digital subtraction angiography (DSA) images acquired by FPD and I.I. We have found from the clinical images that the FPD is superior to the I.I. in depiction of fine blood vessels as well as of physical characteristics. Fluoroscopy images acquired by the FPD were not entirely satisfactory, however the improvement made in its performance now permits equal use of the FPD and I.I. systems.

  4. Nerve growth factor-mediated regulation of pain signalling and proposed new intervention strategies in clinical pain management. (United States)

    McKelvey, Laura; Shorten, George D; O'Keeffe, Gerard W


    Nerve growth factor (NGF) is the founding member of the neurotrophins family of proteins. It was discovered more than half a century ago through its ability to promote sensory and sympathetic neuronal survival and axonal growth during the development of the peripheral nervous system, and is the paradigmatic target-derived neurotrophic factor on which the neurotrophic hypothesis is based. Since that time, NGF has also been shown to play a key role in the generation of acute and chronic pain and in hyperalgesia in diverse pain states. NGF is expressed at high levels in damaged or inflamed tissues and facilitates pain transmission by nociceptive neurons through a variety of mechanisms. Genetic mutations in NGF or its tyrosine kinase receptor TrkA, lead to a congenital insensitivity or a decreased ability of humans to perceive pain. The hereditary sensory autonomic neuropathies (HSANs) encompass a spectrum of neuropathies that affect one's ability to perceive sensation. HSAN type IV and HSAN type V are caused by mutations in TrkA and NGF respectively. This review will focus firstly on the biology of NGF and its role in pain modulation. We will review neuropathies and clinical presentations that result from the disruption of NGF signalling in HSAN type IV and HSAN type V and review current advances in developing anti-NGF therapy for the clinical management of pain.

  5. Compassionate use of interventions: results of a European Clinical Research Infrastructures Network (ECRIN) survey of ten European countries

    Whitfield, Kate


    Abstract Background \\'Compassionate use\\' programmes allow medicinal products that are not authorised, but are in the development process, to be made available to patients with a severe disease who have no other satisfactory treatment available to them. We sought to understand how such programmes are regulated in ten European Union countries. Methods The European Clinical Research Infrastructures Network (ECRIN) conducted a comprehensive survey on clinical research regulatory requirements, including questions on regulations of \\'compassionate use\\' programmes. Ten European countries, covering approximately 70% of the EU population, were included in the survey (Austria, Denmark, France, Germany, Hungary, Ireland, Italy, Spain, Sweden, and the UK). Results European Regulation 726\\/2004\\/EC is clear on the intentions of \\'compassionate use\\' programmes and aimed to harmonise them in the European Union. The survey reveals that different countries have adopted different requirements and that \\'compassionate use\\' is not interpreted in the same way across Europe. Four of the ten countries surveyed have no formal regulatory system for the programmes. We discuss the need for \\'compassionate use\\' programmes and their regulation where protection of patients is paramount. Conclusions \\'Compassionate use\\' is a misleading term and should be replaced with \\'expanded access\\'. There is a need for expanded access programmes in order to serve the interests of seriously ill patients who have no other treatment options. To protect these patients, European legislation needs to be more explicit and informative with regard to the regulatory requirements, restrictions, and responsibilities in expanded access programmes.

    Chen, Zhao-hua; Huang, Qin; Deng, Ya-zhong; Zhang, Yue; Xu, Yu; Yu, Hao; Liu, Zong-fan


    Data quality management system is essential to ensure accurate, complete, consistent, and reliable data collection in clinical research. This paper is devoted to various choices of data quality metrics. They are categorized by study status, e.g. study start up, conduct, and close-out. In each category, metrics for different purposes are listed according to ALCOA+ principles such us completeness, accuracy, timeliness, traceability, etc. Some general quality metrics frequently used are also introduced. This paper contains detail information as much as possible to each metric by providing definition, purpose, evaluation, referenced benchmark, and recommended targets in favor of real practice. It is important that sponsors and data management service providers establish a robust integrated clinical trial data quality management system to ensure sustainable high quality of clinical trial deliverables. It will also support enterprise level of data evaluation and bench marking the quality of data across projects, sponsors, data management service providers by using objective metrics from the real clinical trials. We hope this will be a significant input to accelerate the improvement of clinical trial data quality in the industry.

  7. The Smart Drug Delivery System and Its Clinical Potential. (United States)

    Liu, Dong; Yang, Fang; Xiong, Fei; Gu, Ning


    With the unprecedented progresses of biomedical nanotechnology during the past few decades, conventional drug delivery systems (DDSs) have been involved into smart DDSs with stimuli-responsive characteristics. Benefiting from the response to specific internal or external triggers, those well-defined nanoplatforms can increase the drug targeting efficacy, in the meantime, reduce side effects/toxicities of payloads, which are key factors for improving patient compliance. In academic field, variety of smart DDSs have been abundantly demonstrated for various intriguing systems, such as stimuli-responsive polymeric nanoparticles, liposomes, metals/metal oxides, and exosomes. However, these nanoplatforms are lack of standardized manufacturing method, toxicity assessment experience, and clear relevance between the pre-clinical and clinical studies, resulting in the huge difficulties to obtain regulatory and ethics approval. Therefore, such relatively complex stimulus-sensitive nano-DDSs are not currently approved for clinical use. In this review, we highlight the recent advances of smart nanoplatforms for targeting drug delivery. Furthermore, the clinical translation obstacles faced by these smart nanoplatforms have been reviewed and discussed. We also present the future directions and perspectives of stimuli-sensitive DDS in clinical applications.

P.; Soher, Brian J.; Tkáč, Ivan; Vigneron, Daniel B.; Kauppinen, Risto A.


    A large body of published work shows that proton (hydrogen 1 [1H]) magnetic resonance (MR) spectroscopy has evolved from a research tool into a clinical neuroimaging modality. Herein, the authors present a summary of brain disorders in which MR spectroscopy has an impact on patient management, together with a critical consideration of common data acquisition and processing procedures. The article documents the impact of 1H MR spectroscopy in the clinical evaluation of disorders of the central nervous system. The clinical usefulness of 1H MR spectroscopy has been established for brain neoplasms, neonatal and pediatric disorders (hypoxia-ischemia, inherited metabolic diseases, and traumatic brain injury), demyelinating disorders, and infectious brain lesions. The growing list of disorders for which 1H MR spectroscopy may contribute to patient management extends to neurodegenerative diseases, epilepsy, and stroke. To facilitate expanded clinical acceptance and standardization of MR spectroscopy methodology, guidelines are provided for data acquisition and analysis, quality assessment, and interpretation. Finally, the authors offer recommendations to expedite the use of robust MR spectroscopy methodology in the clinical setting, including incorporation of technical advances on clinical units. © RSNA, 2014 Online supplemental material is available for this article.

  13. Interventional MRI

    Energy Technology Data Exchange (ETDEWEB)

    Fukatsu, Hiroshi [Nagoya Univ. (Japan). School of Medicine


    MR guided interventional procedures have become useful clinical tools recently. In this article the authors discuss the usefulness and problems of MR-guided needle biopsy and MR-guided laser induced thermotherapy (LITT) for clinical cases. MR enabled optimal plane monitoring with desired image contrast during the procedure without X-ray irradiation for puncture and tissue sampling. Also only MR could non-invasively provide interstitial temperature information during laser ablation. Bone and soft tissue lesions are likely to be candidates for MR interventions because they are free from any physiological motions, and radiologists should compare MR-guidance with CT- or US guidance for individual cases in order to achieve a less invasive diagnosis or treatment.

    Full Text Available Abstract Background US Latinos have greater prevalence of type 2 diabetes (diabetes, uncontrolled diabetes and diabetes co-morbidities compared to non-Latino Whites. They also have lower literacy levels and are more likely to live in poverty. Interventions are needed to improve diabetes control among low-income Latinos. Methods and design This randomized clinical trial tested the efficacy of a culturally- and literacy-tailored diabetes self-management intervention (Latinos en Control on glycemic control among low-income Latinos with diabetes, compared to usual care (control. Participants were recruited from five community health centers (CHCs in Massachusetts. The theory-based intervention included an intensive phase of 12 weekly sessions and a follow-up maintenance phase of 8 monthly sessions. Assessments occurred at baseline, and at 4 and 12 months. The primary outcome was glycosylated hemoglobin (HbA1c. Secondary outcomes were self-management behaviors, weight, lipids and blood pressure. Additional outcomes included diabetes knowledge, self-efficacy, depression and quality of life. The study was designed for recruitment of 250 participants (estimated 20% dropout rate to provide 90% power for detecting a 7% or greater change in HbA1c between the intervention and control groups. This is a difference in change of HbA1c of 0.5 to 0.6%. Discussion Low-income Latinos bear a great burden of uncontrolled diabetes and are an understudied population. Theory-based interventions that are tailored to the needs of this high-risk population have potential for improving diabetes self-management and reduce health disparities. This article describes the design and methods of a theory driven intervention aimed at addressing this need. Trial registration # NCT00848315

[Academic Medical Center–University of Amsterdam, Amsterdam (Netherlands); Mehta, Rajendra H. [Duke Clinical Research Institute, Durham, NC (United States); Winter, Robbert J. de [Academic Medical Center–University of Amsterdam, Amsterdam (Netherlands)


    Background: Percutaneous coronary intervention (PCI) of saphenous vein grafts (SVG) poses a high-risk for distal coronary thromboembolic events. Glycoprotein IIb/IIIa inhibitors are frequently used in hope of reducing the impact of this, although the safety and efficacy of these drugs to improve outcomes in this setting are understudied. Methods: Patients were included if they had prior coronary artery bypass surgery and subsequently underwent PCI of ≥ 1 SVG graft at a Dutch academic center between 1997 and 2008. These patients were matched 1:1 based on peri-procedural use of abciximab using a propensity-score matching algorithm based on 17 variables. Conditional logistic regression and Cox regression stratified on matched pairs were performed to evaluate the association between abciximab use and MACCE (the composite measure of mortality, myocardial infarction, stroke and repeat revascularization) at 30 days and up to 1 year. Results: The composite of 30-day MACCE occurred in 18 patients (15.3%) in the abciximab group and 16 patients (13.6%) in the propensity matched control group (OR: 1.13, 95% CI: 0.57–2.21, p = 0.73). At 1-year follow-up, MACCE rates were also similar (32.5% vs. 33.9%, HR: 0.97, 95% CI: 0.59–1.59). Major bleeding (BARC types 3a–c) was higher in the abciximab group (11.9% vs. 4.2%, OR: 2.80, 95% CI: 1.01–7.77). Ischemic outcomes did not differ among patients with acute coronary syndromes. Conclusion: The use of intravenous abciximab was not associated with improved clinical outcomes up to 1-year among patients undergoing SVG PCI, but was related to more bleeding. - Highlights: • PCI of SVG poses a high-risk for distal coronary thromboembolic events. • Glycoprotein IIb/IIIa inhibitors are frequently used in an attempt to reduce this risk. • We evaluated the safety and efficacy of abciximab (a glycoprotein IIb/IIIa inhibitor) using a propensity-score matched analysis of 236 patients at a large academic medical center. • Thirty

    Chang, Larry W; Njie-Carr, Veronica; Kalenge, Sheila; Kelly, Jack F; Bollinger, Robert C; Alamo-Talisuna, Stella


    Mobile technologies for health (mHealth) represents a growing array of tools being applied in diverse health care settings. mHealth interventions for improving HIV/AIDS care is a promising strategy, but its evidence base is limited. We conducted a formative research evaluation to inform the development of novel mHealth HIV/AIDS care interventions to be used by community health workers (CHWs) in Kampala, Uganda. A mixed methods formative research approach was utilized. Qualitative methods included 20 in-depth interviews (IDIs) and six focus groups with CHWs, clinic staff, and patients. Thematic analysis was performed and selected quotations used to illustrate themes. Quantitative methods consisted of a survey administered to CHWs and clinic staff, using categorical and Likert scale questions regarding current mobile phone and internet access and perceptions on the potential use of smartphones by CHWs. Qualitative results included themes on significant current care challenges, multiple perceived mHealth benefits, and general intervention acceptability. Key mHealth features desired included tools to verify CHWs' task completions, clinical decision support tools, and simple access to voice calling. Inhibiting factors identified included concerns about CHWs' job security and unrealistic expectations of mHealth capabilities. Quantitative results from 27 staff participants found that 26 (96%) did not have internet access at home, yet only 2 (7.4%) did not own a mobile phone. Likert scale survey responses (1-5, 1 = Strongly Disagree, 5 = Strongly Agree) indicated general agreement that smartphones would improve efficiency (Mean = 4.35) and patient care (4.31) but might be harmful to patient confidentiality (3.88) and training was needed (4.63). Qualitative and quantitative results were generally consistent, and, overall, there was enthusiasm for mHealth technology. However, a number of potential inhibiting factors were also discovered. Findings from this study may help

CONCLUSION: The Ministry of Health ensured investments to encourage clinical research in Brazil and contributed towards promoting cohesion between investigators, health policies and the healthcare industrial production complex.

  19. Original research paper. Public health care system, a quasi-experimental study: Acceptance and attitude to implicate clinical services. (United States)

    Gillani, Syed Wasif; Abdul, Mohi Iqbal Mohammad


    A six-month longitudinal intervention arm study with a pre-post cross-sectional questionnaire-based survey was performed. A 3-phase objective structured clinical examination (OSCE) design was utilized for evaluation of acceptance and attitude of pharmacy students towards clinical pharmacy services. The pre-OSCE survey showed increased disagreement with the role of clinical pharmacists, compared to a significant positive shift in attitude towards their services in the healthcare team after 6 months of the trial. Responses improved for awareness (the current healthcare system could be improved by involving pharmacists, p model suggested a strong positive effect on patient interaction, medical information tasks, clinical decisions on drug-related problems (DRPs), and communication with healthcare professionals (R2 = 0.41, F = 1.51, p < 0.001).

  20. Liposomal drug delivery systems: from concept to clinical applications. (United States)

    Allen, Theresa M; Cullis, Pieter R


    The first closed bilayer phospholipid systems, called liposomes, were described in 1965 and soon were proposed as drug delivery systems. The pioneering work of countless liposome researchers over almost 5 decades led to the development of important technical advances such as remote drug loading, extrusion for homogeneous size, long-circulating (PEGylated) liposomes, triggered release liposomes, liposomes containing nucleic acid polymers, ligand-targeted liposomes and liposomes containing combinations of drugs. These advances have led to numerous clinical trials in such diverse areas as the delivery of anti-cancer, anti-fungal and antibiotic drugs, the delivery of gene medicines, and the delivery of anesthetics and anti-inflammatory drugs. A number of liposomes (lipidic nanoparticles) are on the market, and many more are in the pipeline. Lipidic nanoparticles are the first nanomedicine delivery system to make the transition from concept to clinical application, and they are now an established technology platform with considerable clinical acceptance. We can look forward to many more clinical products in the future.

  1. Driver's behavioural changes with new intelligent transport system interventions at railway level crossings--A driving simulator study. (United States)

    Larue, Grégoire S; Kim, Inhi; Rakotonirainy, Andry; Haworth, Narelle L; Ferreira, Luis


    Improving safety at railway level crossings is an important issue for the Australian transport system. Governments, the rail industry and road organisations have tried a variety of countermeasures for many years to improve railway level crossing safety. New types of intelligent transport system (ITS) interventions are now emerging due to the availability and the affordability of technology. These interventions target both actively and passively protected railway level crossings and attempt to address drivers' errors at railway crossings, which are mainly a failure to detect the crossing or the train and misjudgement of the train approach speed and distance. This study aims to assess the effectiveness of three emerging ITS that the rail industry considers implementing in Australia: a visual in-vehicle ITS, an audio in-vehicle ITS, as well as an on-road flashing beacons intervention. The evaluation was conducted on an advanced driving simulator with 20 participants per trialled technology, each participant driving once without any technology and once with one of the ITS interventions. Every participant drove through a range of active and passive crossings with and without trains approaching. Their speed approach of the crossing, head movements and stopping compliance were measured. Results showed that driver behaviour was changed with the three ITS interventions at passive crossings, while limited effects were found at active crossings, even with reduced visibility. The on-road intervention trialled was unsuccessful in improving driver behaviour; the audio and visual ITS improved driver behaviour when a train was approaching. A trend toward worsening driver behaviour with the visual ITS was observed when no trains were approaching. This trend was not observed for the audio ITS intervention, which appears to be the ITS intervention with the highest potential for improving safety at passive crossings.

  2. Comparative efficacy of two primary care interventions to assist withdrawal from long term benzodiazepine use: A protocol for a clustered, randomized clinical trial

    Roca Miguel


    Full Text Available Abstract Background Although benzodiazepines are effective, long-term use is not recommended because of potential adverse effects; the risks of tolerance and dependence; and an increased risk of hip fractures, motor vehicle accidents, and memory impairment. The estimated prevalence of long-term benzodiazepine use in the general population is about 2,2 to 2,6%, is higher in women and increases steadily with age. Interventions performed by General Practitioners may help patients to discontinue long-term benzodiazepine use. We have designed a trial to evaluate the effectiveness and safety of two brief general practitioner-provided interventions, based on gradual dose reduction, and will compare the effectiveness of these interventions with that of routine clinical practice. Methods/Design In a three-arm cluster randomized controlled trial, general practitioners will be randomly allocated to: a a group in which the first patient visit will feature a structured interview, followed by visits every 2-3 weeks to the end of dose reduction; b a group in which the first patient visit will feature a structured interview plus delivery of written instructions to self-reduce benzodiazepine dose, or c routine care. Using a computerized pharmaceutical prescription database, 495 patients, aged 18-80 years, taking benzodiazepine for at least 6 months, will be recruited in primary care health districts of three regions of Spain (the Balearic Islands, Catalonia, and Valencia. The primary outcome will be benzodiazepine use at 12 months. The secondary outcomes will include measurements of anxiety and depression symptoms, benzodiazepine dependence, quality of sleep, and alcohol consumption. Discussion Although some interventions have been shown to be effective in reducing benzodiazepine consumption by long-term users, the clinical relevance of such interventions is limited by their complexity. This randomized trial will compare the effectiveness and safety of two

  3. Evidence-Based Psychological Interventions for the Management of Pediatric Chronic Pain: New Directions in Research and Clinical Practice (United States)

    Coakley, Rachael; Wihak, Tessa


    Over the past 20 years our knowledge about evidence-based psychological interventions for pediatric chronic pain has dramatically increased. Overall, the evidence in support of psychological interventions for pediatric chronic pain is strong, demonstrating positive psychological and behavioral effects for a variety of children with a range of pain conditions. However, wide scale access to effective psychologically-based pain management treatments remains a challenge for many children who suffer with pain. Increasing access to care and reducing persistent biomedical biases that inhibit attainment of psychological services are a central focus of current pain treatment interventions. Additionally, as the number of evidence-based treatments increase, tailoring treatments to a child or family’s particular needs is increasingly possible. This article will (1) discuss the theoretical frameworks as well as the specific psychological skills and strategies that currently hold promise as effective agents of change; (2) review and summarize trends in the development of well-researched outpatient interventions over the past ten years; and (3) discuss future directions for intervention research on pediatric chronic pain.

  5. Efficacy of a brief multifactorial adherence-based intervention on reducing the blood pressure of patients with poor adherence: protocol for a randomized clinical trial

    Directory of Open Access Journals (Sweden)

    Llobera Joan


    Full Text Available Abstract Background Lowering of blood pressure by antihypertensive drugs reduces the risks of cardiovascular events, stroke, and total mortality. However, poor adherence to antihypertensive medications reduces their effectiveness and increases the risk of adverse events. In terms of relative risk reduction, an improvement in medication adherence could be as effective as the development of a new drug. Methods/Design The proposed randomized controlled trial will include patients with a low adherence to medication and uncontrolled blood pressure. The intervention group will receive a multifactorial intervention during the first, third, and ninth months, to improve adherence. This intervention will include motivational interviews, pill reminders, family support, blood pressure self-recording, and simplification of the dosing regimen. Measurement The primary outcome is systolic blood pressure. The secondary outcomes are diastolic blood pressure, proportion of patients with adequately controlled blood pressure, and total cost. Discussion The trial will evaluate the impact of a multifactorial adherence intervention in routine clinical practice.

  6. Effectiveness of a nursing intervention in decreasing the anxiety levels of family members of patients undergoing cardiac surgery: a randomized clinical trial (United States)

    Hamester, Letícia; de Souza, Emiliane Nogueira; Cielo, Cibele; Moraes, Maria Antonieta; Pellanda, Lúcia Campos


    ABSTRACT Objective: to verify the effectiveness of nursing orientation provided to families of patients in the immediate post-operative following cardiac surgery before the first visit to the post-anesthesia care unit, in decreasing anxiety levels, compared to the unit's routine orientation. Method: open randomized clinical trial addressing family members in the waiting room before the first visit in the immediate post-operative period. The family members assigned to the intervention group received audiovisual orientation concerning the patients' conditions at the time and the control group received the unit's routine orientation. Outcome anxiety was assessed using the STAI-State. Results: 210 individuals were included, 105 in each group, aged 46.4 years old on average (±14.5); 69% were female and 41% were the patients' children. The mean score obtained on the anxiety assessment in the intervention group was 41.3±8.6, while the control group scored 50.6±9.4 (p<0.001). Conclusion: a nursing intervention focused on providing guidance to families before their first visit to patients in the immediate post-operative period of cardiac surgery helps to decrease the levels of anxiety of companions, making them feel better prepared for the moment.
