    To analyse and define the concept "evidence based practice readiness" in nurses. Evidence based practice readiness is a term commonly used in health literature, but without a clear understanding of what readiness means. Concept analysis is needed to define the meaning of evidence based practice readiness. A concept analysis was conducted using Walker and Avant's method to clarify the defining attributes of evidence based practice readiness as well as antecedents and consequences. A Boolean search of PubMed and Cumulative Index for Nursing and Allied Health Literature was conducted and limited to those published after the year 2000. Eleven articles met the inclusion criteria for this analysis. Evidence based practice readiness incorporates personal and organisational readiness. Antecedents include the ability to recognize the need for evidence based practice, ability to access and interpret evidence based practice, and a supportive environment. The concept analysis demonstrates the complexity of the concept and its implications for nursing practice. The four pillars of evidence based practice readiness: nursing, training, equipping and leadership support are necessary to achieve evidence based practice readiness. Nurse managers are in the position to address all elements of evidence based practice readiness. Creating an environment that fosters evidence based practice can improve patient outcomes, decreased health care cost, increase nurses' job satisfaction and decrease nursing turnover. © 2018 John Wiley & Sons Ltd.

    Evidence-based practice (EBP) is a model of professional decision-making in which practitioners integrate the best available evidence with client values/context and clinical expertise in order to provide services for their clients. This framework provides behavior analysts with a structure for pervasive use of the best available evidence in the complex settings in which they work. This structure recognizes the need for clear and explicit understanding of the strength of evidence supporting intervention options, the important contextual factors including client values that contribute to decision making, and the key role of clinical expertise in the conceptualization, intervention, and evaluation of cases. Opening the discussion of EBP in this journal, Smith (The Behavior Analyst, 36, 7-33, 2013) raised several key issues related to EBP and applied behavior analysis (ABA). The purpose of this paper is to respond to Smith's arguments and extend the discussion of the relevant issues. Although we support many of Smith's (The Behavior Analyst, 36, 7-33, 2013) points, we contend that Smith's definition of EBP is significantly narrower than definitions that are used in professions with long histories of EBP and that this narrowness conflicts with the principles that drive applied behavior analytic practice. We offer a definition and framework for EBP that aligns with the foundations of ABA and is consistent with well-established definitions of EBP in medicine, psychology, and other professions. In addition to supporting the systematic use of research evidence in behavior analytic decision making, this definition can promote clear communication about treatment decisions across disciplines and with important outside institutions such as insurance companies and granting agencies.

    Full Text Available Psychosocial interventions that are applied in practice should be those that have received the best scientific evidence about their effectiveness. Evidence-Based Psychosocial Intervention is a methodological tool that aims to raise awareness among professionals and policy makers of the need for professional practice to be guided by the best evidence. For this purpose, systematic reviews and meta-analyses of empirical evaluation studies play an important role as they allow us to synthesize the results of numerous studies on the same issue to determine which are the best treatments and interventions for solving the problem. This article presents an overview of the meta-analyses and the information they can provide for professional practice. The phases in which a meta-analysis is carried out are outlined as follows: (a formulating the problem, (b searching for the studies, (c coding the studies, (d calculating the effect size, (e statistical techniques of integration and (f publishing the study. The scope of meta-analyses and their results are illustrated with an example and their implications for professional practice are discussed.

(1) Those at risk for developing pressure ulcers include the elderly and critically ill as well as persons with neurological impairments and those who suffer conditions associated with immobility. Pressure ulcers are graded or staged with a 4-point classification system denoting severity. Stage I represents the beginnings of a pressure ulcer and stage IV, the severest grade, consists of full thickness tissue loss with exposed bone, tendon, and or muscle. (1) In a 2004 survey of Canadian health care settings, Woodbury and Houghton (2) estimated that the prevalence of pressure ulcers at a stage 1 or greater in Ontario ranged between 13.1% and 53% with nonacute health care settings having the highest prevalence rate (Table 1).

A pressure ulcer is a localized injury to the skin and/or underlying tissue usually over a bony prominence, as a result of pressure, or pressure in conjunction with shear and/or friction. Many areas of the body, especially the sacrum and the heel, are prone to the development of pressure ulcers. People with impaired mobility (e.g., stroke or spinal cord injury patients) are most vulnerable to pressure ulcers. Other factors that predispose people to pressure ulcer formation are poor nutrition, poor sensation, urinary and fecal incontinence, and poor overall physical and mental health. The prevalence of pressure ulcers in Ontario has been estimated to range from a median of 22.1% in community settings to a median of 29.9% in nonacute care facilities. Pressure ulcers have been shown to increase the risk of mortality among geriatric patients by as much as 400%, to increase the frequency

    2006-01-01

    The objective of this analysis is to review a spectrum of functional brain imaging technologies to identify whether there are any imaging modalities that are more effective than others for various brain pathology conditions. This evidence-based analysis reviews magnetoencephalography (MEG), magnetic resonance spectroscopy (MRS), positron emission tomography (PET), and functional magnetic resonance imaging (fMRI) for the diagnosis or surgical management of the following conditions: Alzheimer's disease (AD), brain tumours, epilepsy, multiple sclerosis (MS), and Parkinson's disease (PD). TARGET POPULATION AND CONDITION Alzheimer's disease is a progressive, degenerative, neurologic condition characterized by cognitive impairment and memory loss. The Canadian Study on Health and Aging estimated that there will be 97,000 incident cases (about 60,000 women) of dementia (including AD) in Canada in 2006. In Ontario, there will be an estimated 950 new cases and 580 deaths due to brain cancer in 2006. Treatments for brain tumours include surgery and radiation therapy. However, one of the limitations of radiation therapy is that it damages tissue though necrosis and scarring. Computed tomography (CT) and magnetic resonance imaging (MRI) may not distinguish between radiation effects and resistant tissue, creating a potential role for functional brain imaging. Epilepsy is a chronic disorder that provokes repetitive seizures. In Ontario, the rate of epilepsy is estimated to be 5 cases per 1,000 people. Most people with epilepsy are effectively managed with drug therapy; but about 50% do not respond to drug therapy. Surgical resection of the seizure foci may be considered in these patients, and functional brain imaging may play a role in localizing the seizure foci. Multiple sclerosis is a progressive, inflammatory, demyelinating disease of the central nervous system (CNS). The cause of MS is unknown; however, it is thought to be due to a combination of etiologies, including

  7. Intrathecal baclofen pump for spasticity: an evidence-based analysis.

    Science.gov (United States)

    2005-01-01

    To conduct an evidence-based analysis of the effectiveness and cost-effectiveness of intrathecal baclofen for spasticity. Spasticity is a motor disorder characterized by tight or stiff muscles that may interfere with voluntary muscle movements and is a problem for many patients with multiple sclerosis (MS), spinal cord injury (SCI), cerebral palsy (CP), and acquired brain injury (ABI).(1). Increased tone and spasm reduces mobility and independence, and interferes with activities of daily living, continence and sleep patterns. Spasticity may also be associated with significant pain or discomfort (e.g., due to poor fit in braces, footwear, or wheelchairs), skin breakdown, contractures, sleep disorders and difficulty in transfer. Goals of treatment are to decrease spasticity in order to improve range of motion, facilitate movement, reduce energy expenditure and reduce risk of contractures. Existing treatments include physical therapy, oral medications, injections of phenol or botulinum toxin, or surgical intervention. Baclofen is the oral drug most frequently prescribed for spasticity in cases of SCI and MS.(1) Baclofen is a muscle relaxant and antispasticity drug. In the brain, baclofen delivered orally has some supraspinal activity that may contribute to clinical side effects. The main adverse effects of oral baclofen include sedation, excessive weakness, dizziness, mental confusion, and somnolence.(2) The incidence of adverse effects is reported to range from 10% to 75%.(2) Ochs et al. estimated that approximately 25-30% of SCI and MS patients fail to respond to oral baclofen.(3;4) Adverse effects appear to be dose-related and may be minimized by initiating treatment at a low dose and gradually titrating upwards.(2) Adverse effects usually appear at doses >60 mg/day.(2) The rate of treatment discontinuation due to intolerable adverse effects has generally been reported to range from 4% to 27%.(2) When baclofen is administered orally, only a small portion of the

    arrhythmias (secondary prevention) is an insured service in Ontario. Primary prevention of SCD involves identification of and preventive therapy for patients who are at high risk for SCD. Most of the studies in the literature that have examined the prevention of fatal ventricular arrhythmias have focused on patients with ischemic heart disease, in particular, those with heart failure (HF), which has been shown to increase the risk of SCD. The risk of HF is determined by left ventricular ejection fraction (LVEF); most studies have focused on patients with an LVEF under 0.35 or 0.30. While most studies have found ICDs to reduce significantly the risk for SCD in patients with an LVEF less than 0.35, a more recent study (Sudden Cardiac Death in Heart Failure Trial [SCD-HeFT]) reported that patients with HF with nonischemic heart disease could also benefit from this technology. Based on the generalization of the SCD-HeFT study, the Centers for Medicare and Medicaid in the United States recently announced that it would allocate $10 billion (US) annually toward the primary prevention of SCD for patients with ischemic and nonischemic heart disease and an LVEF under 0.35. The aim of this literature review was to assess the effectiveness, safety, and cost effectiveness of ICDs for the primary prevention of SCD. The standard search strategy used by the Medical Advisory Secretariat was used. This included a search of all international health technology assessments as well as a search of the medical literature from January 2003-May 2005. A modification of the GRADE approach (1) was used to make judgments about the quality of evidence and strength of recommendations systematically and explicitly. GRADE provides a framework for structured reflection and can help to ensure that appropriate judgments are made. GRADE takes into account a study's design, quality, consistency, and directness in judging the quality of evidence for each outcome. The balance between benefits and harms, quality of

    2014-01-01

    Background Dyslipidemias include high levels of total cholesterol, low-density lipoprotein (LDL) cholesterol, and triglycerides and low levels of high-density lipoprotein (HDL) cholesterol. Dyslipidemia is a risk factor for cardiovascular disease, which is a major contributor to mortality in Canada. Approximately 23% of the 2009/11 Canadian Health Measures Survey (CHMS) participants had a high level of LDL cholesterol, with prevalence increasing with age, and approximately 15% had a total cholesterol to HDL ratio above the threshold. Objectives To evaluate the frequency of lipid testing in adults not diagnosed with dyslipidemia and in adults on treatment for dyslipidemia. Research Methods A systematic review of the literature set out to identify randomized controlled trials (RCTs), systematic reviews, health technology assessments (HTAs), and observational studies published between January 1, 2000, and November 29, 2012, that evaluated the frequency of testing for dyslipidemia in the 2 populations. Results Two observational studies assessed the frequency of lipid testing, 1 in individuals not on lipid-lowering medications and 1 in treated individuals. Both studies were based on previously collected data intended for a different objective and, therefore, no conclusions could be reached about the frequency of testing at intervals other than the ones used in the original studies. Given this limitation and generalizability issues, the quality of evidence was considered very low. No evidence for the frequency of lipid testing was identified in the 2 HTAs included. Canadian and international guidelines recommend testing for dyslipidemia in individuals at an increased risk for cardiovascular disease. The frequency of testing recommended is based on expert consensus. Conclusions Conclusions on the frequency of lipid testing could not be made based on the 2 observational studies. Current guidelines recommend lipid testing in adults with increased cardiovascular risk, with

    Full Text Available Introduction: One of the ovarian carcinogenesis theories was the presence of premalignant cells in the epithelium of the fallopian tube. Therefore, the prophylactic salpingectomy during benign gynecological surgery is now expected as the attempt to reduce the ovarian cancer incidence. We studied the effect of prophylactic bilateral salpingectomy (PBS in reducing the ovarian cancer incidence. Methods: This evidence-based report resulted from critical appraisal of 5 articles. It is aimed to answer our clinical question, can bilateral prophylactic salpingectomy reduce the incidence of ovarian cancer among women underwent hysterectomy for benign condition or permanent contraception surgery? The search was conducted on the Cochrane Library®, PubMed®, and Embase® using keywords of “prophylactic salpingectomy,” and “ovarian cancer incidence.” Reference lists of relevant articles were searched for other possibly relevant articles. Results: Five studies were included in our appraisal. The incidence of ovarian cancer among women underwent prophylactic salpingectomy is lower compared to women who were not underwent any intervention (2.2% to 13% and 4.75% to 24.4%. The salpingectomy may reduce 29.2% to 64% of ovarian cancer incidence. No significant effect of PBS to ovarian function, quality of life, sexuality, surgery duration, and its cost-effective profile were also found throughout our literature study. Conclusion: PBS is suggested to be performed for women during benign gynecological surgery as a primary preventive strategy of ovarian cancer. PBS is a cost-effective procedure, risk-reducing for ovarian cancer and has no significant effect to the ovarian function.

    Full Text Available Purpose: In current economy, where ICT plays a crucial role for being competitive and effective, businesses are facing higher pressures of flexibility and efficiency than ever before. Transparency is often considered as a suitable mechanism for better market prices and more efficient market environment. Electronic business environment provides the possibility to set up more transparent environment and bring higher competitiveness and efficiency on the market. The paper analyse the impact of transparency on prices in e-procurement.Methodology: Reverse auctions are considered as transparent tool simulating in partial level real competition. Together, it allows to examine several levels of transparency set up in auction negotiation process. The impact of transparency on final prices was analysed on real data using relation based analysis were different situations of transparency set up is compared against achieved final price.Findings: Research results based on real data shows, that generally, the transparency in electronic reverse auction can lead to more negative prices agreed by purchasers as current scientific and commercial promotions.Research limitation: Significance of research results is limited due to still low readiness and skills of e-procurers. The validation of results is needed to realized within longer period of time and from environments with different level of e-readiness. Together, it reveal that transparency is more complex issue where the significance of transparency can reveal its sense in some specific situations on the market and negotiation.Value of paper: Evidenced based research reveal some controversy results which support new scientific efforts in microeconomics and socio-economic impact of ICT fields. Together, it affects real practitioners in way how to use and perceive claimed impact of reverse auction solutions.

    LDL apheresis to acutely remove LDL from the plasma of 3 high-risk patient populations for whom diet has been ineffective and maximum drug therapy has either been ineffective or not tolerated. The 3 patient groups are as follows: Functional hypercholesterolemic homozygotes with LDL-C >500 mg/dL (>13mmol/L);Functional hypercholesterolemic heterozygotes with LDL-C >300 mg/dL (>7.8mmol/L);Functional hypercholesterolemic heterozygotes with LDL-C >200 mg/dL (>5.2mmol/L) and documented CADNo other LDL apheresis system is currently licensed in Canada. The Medical Advisory Secretariat systematically reviewed the literature to assess the effectiveness and safety of LDL apheresis performed with the HELP system for the treatment of patients with refractory HMZ and HTZ FH. A standard search methodology was used to retrieve international health technology assessments and English-language journal articles from selected databases. The GRADE approach was used to systematically and explicitly make judgments about the quality of evidence and strength of recommendations. The search identified 398 articles published from January 1, 1998 to May 30, 2007. Eight studies met the inclusion criteria. Five case series, 2 case series nested within comparative studies, and one retrospective review, were included in the analysis. A health technology assessment conducted by the Alberta Heritage Foundation for Medical Research, and a review by the United States Food and Drug Administration were also included. Large heterogeneity among the studies was observed. Studies varied in inclusion criteria, baseline patient characteristics and methodology. Overall, the mean acute relative decrease in LDL-C with HELP LDL apheresis ranged from 53 to 77%. The mean acute relative reductions ranged as follows: total cholesterol (TC) 47 to 64%, HDL-C +0.

    Full Text Available Objectives: The aim of this review was to systematically examine the available evidence for the effectiveness of prophylactic antibiotics in cases of vesicoureteric reflux (VUR. Materials and Methods: We searched the relevant data on medical management of VUR and the date of last search was June 2008. The search included both randomized controlled trials as well as the nonrandomized trials and the data sources were; MEDLINE, online peer reviewed journals, Cochrane database and abstracts from conference proceedings. Results: Barring few most of the studies published on medical management were nonrandomized. Besides being small in number many of these studies were of poor-quality and poorly designed eventually failing in giving a reliable answer in this regard. Few of the studies suggest that the children with low grade VUR might do well even without antibiotic prophylaxis. Conclusions : In the absence of properly designed, randomized controlled trials and long-term follow-up the question of antibiotic prophylaxis in cases of VUR remains unanswered in large part of it. Whether to give prophylactic antibiotics or not would ultimately need a shared decision-making involving both the treating physician and the parents assessing both the risks and the benefits.

    alternative to catheterization. An economic analysis estimating the budget-impact of BladderScan in complex continuing care facilities was completed. The analysis results indicated a $192,499 (Cdn) cost-savings per year per facility and a cost-savings of $2,887,485 (Cdn) for all 15 CCC facilities. No economic analysis was completed for long-term care and acute care facilities due to lack of data. Rapid diffusion of portable bladder ultrasound technology is expected. Recently, the IC5 project on improving continence care in Ontario's complex continuing care centres piloted portable bladder ultrasound at 12 sites. Preliminary results were promising. Many physicians and health care facilities already have portable bladder ultrasound devices. However, portable bladder ultrasound devices for PVR measurement are not in use at most health care facilities in Ontario and Canada. The Verathon Corporation (Bothell, Wisconsin, United States), which patents BladderScan, is the sole licensed manufacturer of the portable bladder ultrasound in Canada. Field monopoly may influence the rising costs of portable bladder ultrasound, particularly when faced with rapid expansion of the technology. Several thousand residents of Ontario would benefit from portable bladder ultrasound. The number of residents of Ontario that would benefit from the technology is difficult to quantify, because the incidence and prevalence of incontinence are grossly under-reported. However, long-term care and complex continuing care institutions would benefit greatly from portable bladder ultrasound, as would numerous rehabilitation units, postsurgical care units, and urology clinics. The cost of the portable bladder ultrasound devices ranges from $17,698.90 to $19,565.95 (Cdn) (total purchase price per unit as quoted by the manufacturer). Additional training packages, batteries and battery chargers, software, gel pads, and yearly warranties are additional costs. Studies indicate that portable bladder ultrasound is a

    Public health related decisions often have to balance the cost of intervention strategies with the benefit of the reduction in disease burden. While the cost can often be inferred, forward modelling of the effect of different intervention options is complicated and disease specific. Here we introduce a package that is aimed to simplify this process. The package allows one to infer parameters using a Bayesian approach, perform forward modelling of the likely results of the proposed intervention and finally perform cost effectiveness analysis of the results. The package is based on a method previously used in the United Kingdom to inform vaccination strategies for influenza, with extensions to make it easily adaptable to other diseases and data sources.

  17. Team-Based Models for End-of-Life Care: An Evidence-Based Analysis

    Science.gov (United States)

    2014-01-01

    Background End of life refers to the period when people are living with advanced illness that will not stabilize and from which they will not recover and will eventually die. It is not limited to the period immediately before death. Multiple services are required to support people and their families during this time period. The model of care used to deliver these services can affect the quality of the care they receive. Objectives Our objective was to determine whether an optimal team-based model of care exists for service delivery at end of life. In systematically reviewing such models, we considered their core components: team membership, services offered, modes of patient contact, and setting. Data Sources A literature search was performed on October 14, 2013, using Ovid MEDLINE, Ovid MEDLINE In-Process and Other Non-Indexed Citations, Ovid Embase, EBSCO Cumulative Index to Nursing & Allied Health Literature (CINAHL), and EBM Reviews, for studies published from January 1, 2000, to October 14, 2013. Review Methods Abstracts were reviewed by a single reviewer and full-text articles were obtained that met the inclusion criteria. Studies were included if they evaluated a team model of care compared with usual care in an end-of-life adult population. A team was defined as having at least 2 health care disciplines represented. Studies were limited to English publications. A meta-analysis was completed to obtain pooled effect estimates where data permitted. The GRADE quality of the evidence was evaluated. Results Our literature search located 10 randomized controlled trials which, among them, evaluated the following 6 team-based models of care: hospital, direct contact home, direct contact home, indirect contact comprehensive, indirect contact comprehensive, direct contact comprehensive, direct, and early contact Direct contact is when team members see the patient; indirect contact is when they advise another health care practitioner (e.g., a family doctor) who sees

    Full Text Available Evidence-based dental practice requires the developmment and evaluation of protocols that en-sure translational effectiveness: that is, the efficient incorporation of the best available efficacy and effec-tiveness findings in specific clinical dentistry settings and environments. Evidence-based dentistry predi-cates the synthesis of research for obtaining the best available evidence in a validated, stringent, systematic and unbiased fashion. Research synthesis is now established as a science in its own right, precisely because it adheres to the scientific process that is driven by a research question and a hypothesis, follows through clearly defined methodology and design, yielding quantifiable data that are analyzed statistically, and from which stringent statistical inferences are drawn. The conclusions from the protocol of research synthesis define the best available evidence, which is used in the process of evidence-based revision of clinical practice guidelines. One important hurdle of the process of applying research synthesis in evidence-based dentistry lies in the fact that the statistical inferences produced by research must be translated into clinical relevance. Here, we present a model to circumvent this limitation by means of text analysis/mining protocols, which could lead the path toward a novel, valid and reliable ap-proach for the inferential analysis of clinical relevance.

  20. New directions in evidence-based policy research: a critical analysis of the literature.

    2014-07-14

    Despite 40 years of research into evidence-based policy (EBP) and a continued drive from both policymakers and researchers to increase research uptake in policy, barriers to the use of evidence are persistently identified in the literature. However, it is not clear what explains this persistence - whether they represent real factors, or if they are artefacts of approaches used to study EBP. Based on an updated review, this paper analyses this literature to explain persistent barriers and facilitators. We critically describe the literature in terms of its theoretical underpinnings, definitions of 'evidence', methods, and underlying assumptions of research in the field, and aim to illuminate the EBP discourse by comparison with approaches from other fields. Much of the research in this area is theoretically naive, focusing primarily on the uptake of research evidence as opposed to evidence defined more broadly, and privileging academics' research priorities over those of policymakers. Little empirical data analysing the processes or impact of evidence use in policy is available to inform researchers or decision-makers. EBP research often assumes that policymakers do not use evidence and that more evidence - meaning research evidence - use would benefit policymakers and populations. We argue that these assumptions are unsupported, biasing much of EBP research. The agenda of 'getting evidence into policy' has side-lined the empirical description and analysis of how research and policy actually interact in vivo. Rather than asking how research evidence can be made more influential, academics should aim to understand what influences and constitutes policy, and produce more critically and theoretically informed studies of decision-making. We question the main assumptions made by EBP researchers, explore the implications of doing so, and propose new directions for EBP research, and health policy.

    Drug benefit-risk (BR) analysis is based on firm clinical evidence regarding various safety and efficacy outcomes. In this paper, we propose a new and more formal approach for constructing a supporting multi-criteria model that fully takes into account the evidence on efficacy and adverse drug reactions. Our approach is based on the stochastic multi-criteria acceptability analysis methodology, which allows us to compute the typical value judgments that support a decision, to quantify decision uncertainty, and to compute a comprehensive BR profile. We construct a multi-criteria model for the therapeutic group of second-generation antidepressants. We assess fluoxetine and venlafaxine together with placebo according to incidence of treatment response and three common adverse drug reactions by using data from a published study. Our model shows that there are clear trade-offs among the treatment alternatives. Copyright © 2011 John Wiley & Sons, Ltd.

    In June 2008, the Medical Advisory Secretariat began work on the Diabetes Strategy Evidence Project, an evidence-based review of the literature surrounding strategies for successful management and treatment of diabetes. This project came about when the Health System Strategy Division at the Ministry of Health and Long-Term Care subsequently asked the secretariat to provide an evidentiary platform for the Ministry's newly released Diabetes Strategy.After an initial review of the strategy and consultation with experts, the secretariat identified five key areas in which evidence was needed. Evidence-based analyses have been prepared for each of these five areas: insulin pumps, behavioural interventions, bariatric surgery, home telemonitoring, and community based care. For each area, an economic analysis was completed where appropriate and is described in a separate report.To review these titles within the Diabetes Strategy Evidence series, please visit the Medical Advisory Secretariat Web site, http://www.health.gov.on.ca/english/providers/program/mas/masabout.html,DIABETES STRATEGY EVIDENCE PLATFORM: Summary of Evidence-Based AnalysesContinuous Subcutaneous Insulin Infusion Pumps for Type 1 and Type 2 Adult Diabetics: An Evidence-Based AnalysisBehavioural Interventions for Type 2 Diabetes: An Evidence-Based AnalysisBARIATRIC SURGERY FOR PEOPLE WITH DIABETES AND MORBID OBESITY: An Evidence-Based SummaryCommunity-Based Care for the Management of Type 2 Diabetes: An Evidence-Based AnalysisHome Telemonitoring for Type 2 Diabetes: An Evidence-Based AnalysisApplication of the Ontario Diabetes Economic Model (ODEM) to Determine the Cost-effectiveness and Budget Impact of Selected Type 2 Diabetes Interventions in Ontario The purpose of this evidence-based analysis was to examine the effectiveness and cost-effectiveness of bariatric surgery for the management of diabetes in morbidly obese people.

    B12 have been associated with neurocognitive disorders. This evidence-based analysis assessed the usefulness of serum vitamin B12 testing as it relates to brain function. This review found very low quality evidence that suggests a connection between high plasma homocysteine levels (a by-product of B vitamin metabolism in the body) and the onset of dementia. Moderate quality of evidence indicates treatment with vitamin B12 does not improve brain function. Moderate quality of evidence also indicates treatment using oral vitamin B12 supplements is as effective as injections of vitamin B12.

    In July 2009, the Medical Advisory Secretariat (MAS) began work on Non-Invasive Cardiac Imaging Technologies for the Diagnosis of Coronary Artery Disease (CAD), an evidence-based review of the literature surrounding different cardiac imaging modalities to ensure that appropriate technologies are accessed by patients suspected of having CAD. This project came about when the Health Services Branch at the Ministry of Health and Long-Term Care asked MAS to provide an evidentiary platform on effectiveness and cost-effectiveness of non-invasive cardiac imaging modalities.After an initial review of the strategy and consultation with experts, MAS identified five key non-invasive cardiac imaging technologies for the diagnosis of CAD. Evidence-based analyses have been prepared for each of these five imaging modalities: cardiac magnetic resonance imaging, single photon emission computed tomography, 64-slice computed tomographic angiography, stress echocardiography, and stress echocardiography with contrast. For each technology, an economic analysis was also completed (where appropriate). A summary decision analytic model was then developed to encapsulate the data from each of these reports (available on the OHTAC and MAS website).The Non-Invasive Cardiac Imaging Technologies for the Diagnosis of Coronary Artery Disease series is made up of the following reports, which can be publicly accessed at the MAS website at: www.health.gov.on.ca/mas">www.health.gov.on.ca/mas or at www.health.gov.on.ca/english/providers/program/mas/mas_about.htmlSINGLE PHOTON EMISSION COMPUTED TOMOGRAPHY FOR THE DIAGNOSIS OF CORONARY ARTERY DISEASE: An Evidence-Based AnalysisSTRESS ECHOCARDIOGRAPHY FOR THE DIAGNOSIS OF CORONARY ARTERY DISEASE: An Evidence-Based AnalysisSTRESS ECHOCARDIOGRAPHY WITH CONTRAST FOR THE DIAGNOSIS OF CORONARY ARTERY DISEASE: An Evidence-Based Analysis64-Slice Computed Tomographic Angiography for the Diagnosis of Coronary Artery Disease: An Evidence-Based Analysis

  5. Electronic tools for health information exchange: an evidence-based analysis.

    Science.gov (United States)

    2013-01-01

    As patients experience transitions in care, there is a need to share information between care providers in an accurate and timely manner. With the push towards electronic medical records and other electronic tools (eTools) (and away from paper-based health records) for health information exchange, there remains uncertainty around the impact of eTools as a form of communication. To examine the impact of eTools for health information exchange in the context of care coordination for individuals with chronic disease in the community. A literature search was performed on April 26, 2012, using OVID MEDLINE, OVID MEDLINE In-Process and Other Non-Indexed Citations, OVID EMBASE, EBSCO Cumulative Index to Nursing & Allied Health Literature (CINAHL), the Wiley Cochrane Library, and the Centre for Reviews and Dissemination database, for studies published until April 26, 2012 (no start date limit was applied). A systematic literature search was conducted, and meta-analysis conducted where appropriate. Outcomes of interest fell into 4 categories: health services utilization, disease-specific clinical outcomes, process-of-care indicators, and measures of efficiency. The quality of the evidence was assessed individually for each outcome. Expert panels were assembled for stakeholder engagement and contextualization. Eleven articles were identified (4 randomized controlled trials and 7 observational studies). There was moderate quality evidence of a reduction in hospitalizations, hospital length of stay, and emergency department visits following the implementation of an electronically generated laboratory report with recommendations based on clinical guidelines. The evidence showed no difference in disease-specific outcomes; there was no evidence of a positive impact on process-of-care indicators or measures of efficiency. A limited body of research specifically examined eTools for health information exchange in the population and setting of interest. This evidence included a

    Chambers, David W

    2010-01-01

    Both panegyric and criticism of evidence-based dentistry tend to be clumsy because the concept is poorly defined. This analysis identifies several contributions to the profession that have been made under the EBD banner. Although the concept of clinicians integrating clinical epidemiology, the wisdom of their practices, and patients' values is powerful, its implementation has been distorted by a too heavy emphasis of computerized searches for research findings that meet the standards of academics. Although EBD advocates enjoy sharing anecdotal accounts of mistakes others have made, faulting others is not proof that one's own position is correct. There is no systematic, high-quality evidence that EBD is effective. The metaphor of a three-legged stool (evidence, experience, values, and integration) is used as an organizing principle. "Best evidence" has become a preoccupation among EBD enthusiasts. That overlong but thinly developed leg of the stool is critiqued from the perspectives of the criteria for evidence, the difference between internal and external validity, the relationship between evidence and decision making, the ambiguous meaning of "best," and the role of reasonable doubt. The strongest leg of the stool is clinical experience. Although bias exists in all observations (including searches for evidence), there are simple procedures that can be employed in practice to increase useful and objective evidence there, and there are dangers in delegating policy regarding allowable treatments to external groups. Patient and practitioner values are the shortest leg of the stool. As they are so little recognized, their integration in EBD is problematic and ethical tensions exist where paternalism privileges science over patient's self-determined best interests. Four potential approaches to integration are suggested, recognizing that there is virtually no literature on how the "seat" of the three-legged stool works or should work. It is likely that most dentists

    In early August 2007, the Medical Advisory Secretariat began work on the Aging in the Community project, an evidence-based review of the literature surrounding healthy aging in the community. The Health System Strategy Division at the Ministry of Health and Long-Term Care subsequently asked the secretariat to provide an evidentiary platform for the ministry's newly released Aging at Home Strategy.After a broad literature review and consultation with experts, the secretariat identified 4 key areas that strongly predict an elderly person's transition from independent community living to a long-term care home. Evidence-based analyses have been prepared for each of these 4 areas: falls and fall-related injuries, urinary incontinence, dementia, and social isolation. For the first area, falls and fall-related injuries, an economic model is described in a separate report.Please visit the Medical Advisory Secretariat Web site, http://www.health.gov.on.ca/english/providers/program/mas/mas_about.html, to review these titles within the Aging in the Community series.AGING IN THE COMMUNITY: Summary of Evidence-Based AnalysesPrevention of Falls and Fall-Related Injuries in Community-Dwelling Seniors: An Evidence-Based AnalysisBehavioural Interventions for Urinary Incontinence in Community-Dwelling Seniors: An Evidence-Based AnalysisCaregiver- and Patient-Directed Interventions for Dementia: An Evidence-Based AnalysisSocial Isolation in Community-Dwelling Seniors: An Evidence-Based AnalysisThe Falls/Fractures Economic Model in Ontario Residents Aged 65 Years and Over (FEMOR)This report features the evidence-based analysis on caregiver- and patient-directed interventions for dementia and is broken down into 4 sections: IntroductionCaregiver-Directed Interventions for DementiaPatient-Directed Interventions for DementiaEconomic Analysis of Caregiver- and Patient-Directed Interventions for Dementia CAREGIVER-DIRECTED INTERVENTIONS FOR DEMENTIA: To identify interventions that may be

    2008-01-01

    Evidence-based practice (EBP) offers the integration of the best research evidence with clinical knowledge and expertise and patient values. EBP is a well known term in health care. This paper discusses the implementation of EBP into radiography and introduces the term evidence-based radiography. Evidence-based radiography is radiography informed and based on the combination of clinical expertise and the best available research-based evidence, patient preferences and resources available. In Norway, EBP in radiography is being debated and radiographers are discussing the challenges of implementing EBP in both academic and clinical practice. This discussion paper explains why EBP needs to be a basis for a radiography curriculum and a part of radiographers' practice. We argue that Norwegian radiographers must increase participation in research and developing practice within their specific radiographic domain

    2013-09-01

    The purpose of the research was to conduct a quality indicator analysis of studies investigating peer-tutoring for students with a disability in adapted physical education. An electronic search was conducted among English journals published from 1960 to November 2012. Databases included ERIC, PsycINFO, and SPORTDiscus. Fifteen research studies employing group-experimental (Gersten et al., 2005) or single-subject designs (Horner et al., 2005) met inclusion criteria. Each study was assessed for the presence and clarity of quality indicators. Group designs met an average of 62.5% essential and 69% desirable indicators. An average of 80% of indicators was present for single-subject designs. Results suggest claims of peer-tutoring being an evidence-based practice are premature. Recommendations for clarifying and applying the quality indicators are offered. Copyright © 2013 Elsevier Ltd. All rights reserved.

    Despite the ongoing process for the development and dissemination of empirically supported treatments, little attention has been paid to the development of evidence-based diagnostics. The article aims at evaluating diagnostic procedures and instruments in current clinical research in terms of evidence-based assessment. Volumes 2006 and 2007 of three German psychological journals "Psychotherapeut," "Psychotherapie, Psychosomatik und Medizinische Psychologie," and "Zeitschrift für Psychiatrie, Psychologie und Psychotherapie" were screened for empirical reports and articles dealing with diagnostic issues. 93 articles were identified and evaluated. Most studies used psychometrically valid and established instruments for assessment. However, diagnostic interviews were relatively scarce, as were multimodal assessments. Measures used for outcome evaluation often lacked evidence of sensitivity to change. Clinical assessment to date does not meet criteria for evidence-based diagnostics. Implications for research and guideline development are discussed.

    2009-01-01

    The purpose of this evidence based analysis was to determine the effectiveness and safety of ultraviolet phototherapy for moderate-to-severe plaque psoriasis. The specific research questions for the evidence review were as follows: What is the safety of ultraviolet phototherapy for moderate-to-severe plaque psoriasis?What is the effectiveness of ultraviolet phototherapy for moderate-to-severe plaque psoriasis? TARGET POPULATION AND CONDITION Psoriasis is a common chronic, systemic inflammatory disease affecting the skin, nails and occasionally the joints and has a lifelong waning and waxing course. It has a worldwide occurrence with a prevalence of at least 2% of the general population, making it one of the most common systemic inflammatory diseases. The immune-mediated disease has several clinical presentations with the most common (85% - 90%) being plaque psoriasis. Characteristic features of psoriasis include scaling, redness, and elevation of the skin. Patients with psoriasis may also present with a range of disabling symptoms such as pruritus (itching), pain, bleeding, or burning associated with plaque lesions and up to 30% are classified as having moderate-to-severe disease. Further, some psoriasis patients can be complex medical cases in which diabetes, inflammatory bowel disease, and hypertension are more likely to be present than in control populations and 10% also suffer from arthritis (psoriatic arthritis). The etiology of psoriasis is unknown but is thought to result from complex interactions between the environment and predisposing genes. Management of psoriasis is related to the extent of the skin involvement, although its presence on the hands, feet, face or genitalia can present challenges. Moderate-to-severe psoriasis is managed by phototherapy and a range of systemic agents including traditional immunosuppressants such as methotrexate and cyclospsorin. Treatment with modern immunosuppressant agents known as biologicals, which more specifically

    Evidence-based practice (EBP) is an influential interdisciplinary movement that originated in medicine as evidence-based medicine (EBM) about 1992. EBP is of considerable interest to library and information science (LIS) because it focuses on a thorough documentation of the basis for the decision...... making that is established in research as well as an optimization of every link in documentation and search processes. EBP is based on the philosophical doctrine of empiricism and, therefore, it is subject to the criticism that has been raised against empiricism.

    Narrative review. The etiology of adjacent segment degeneration (ASDeg) and adjacent segment disease (ASDz) after lumbar interbody fusion (LIF) remains controversial. The aim of this narrative review was to provide an evidence-based analysis of the peer-reviewed literature on clinical studies of ASDeg and ASDz after LIF. A review was performed utilizing Medline, Embase, and Cochrane databases. Two reviewers independently extracted relevant data from each included study. Statistical comparisons were made when appropriate. Nine articles that matched the inclusion and exclusion criteria were included. All the studies were Level III and retrospective. MINORS scores ranged from 9.5 to 13. Clinical outcomes were assessed in all 9 studies, but only 6 studies used validated outcomes measures. Only 6 studies reported values for both ASDeg and ASDz. ASDeg alone was reported in 3 studies. Due to the variability in the criteria for designation as ASDz (different radiographic modalities) and ASDeg (different outcomes measures), we were unable to calculate frequency-weighted mean values or compare the various surgical techniques. This review highlights the various limitations of the current literature on ASDeg and ASDz after lumbar fusion, specifically the absence of a rigorous definition and classification system and an extraordinary heterogeneity in methodology. There needs to be a fundamental shift in the current ASDeg and ASDz research landscape, toward a consensus, so that the high-level clinical research that is essential for treatment of spinal pathology may become available.

    2005-01-01

    The purpose of this review was to determine the effectiveness and adverse effects of arthroscopic lavage and debridement, with or without lavage, in the treatment of symptoms of osteoarthritis (OA) of the knee, and to conduct an economic analysis if evidence for effectiveness can be established. QUESTIONS ASKED: Does arthroscopic lavage improve motor function and pain associated with OA of the knee?Does arthroscopic debridement improve motor function and pain associated with OA of the knee?If evidence for effectiveness can be established, what is the duration of effect?What are the adverse effects of these procedures?What are the economic considerations if evidence for effectiveness can be established? Osteoarthritis, the most common rheumatologic musculoskeletal disorder, affects about 10% of the Canadian adult population. Although the natural history of OA is not known, it is a degenerative condition that affects the bone cartilage in the joint. It can be diagnosed at earlier ages, particularly within the sports injuries population, though the prevalence of non-injury-related OA increases with increasing age and varies with gender, with women being twice as likely as men to be diagnosed with this condition. Thus, with an aging population, the impact of OA on the health care system is expected to be considerable. Treatments for OA of the knee include conservative or nonpharmacological therapy, like physiotherapy, weight management and exercise; and more generally, intra-articular injections, arthroscopic surgery and knee replacement surgery. Whereas knee replacement surgery is considered an end-of-line intervention, the less invasive surgical procedures of lavage or debridement may be recommended for earlier and more severe disease. Both arthroscopic lavage and debridement are generally indicated in patients with knee joint pain, with or without mechanical problems, that are refractory to medical therapy. The clinical utility of these procedures is unclear, hence

    Full Text Available Abstract Background Interventions to promote positive parenting are often reported to offer good outcomes for children but they can consume substantial resources and they require rigorous appraisal. Methods Evaluations of the Triple P parenting program were subjected to systematic review and meta-analysis with analysis of biases. PsychInfo, Embase and Ovid Medline were used as data sources. We selected published articles reporting any child-based outcome in which any variant of Triple P was evaluated in relation to a comparison condition. Unpublished data, papers in languages other than English and some book chapters were not examined. Studies reporting Eyberg Child Behavior Inventory or Child Behavior Checklist scores as outcomes were used in the meta-analysis. Results A total of 33 eligible studies was identified, most involving media-recruited families. Thirty-one of these 33 studies compared Triple P interventions with waiting list or no-treatment comparison groups. Most papers only reported maternal assessments of child behavior. Twenty-three papers were incorporated in the meta-analysis. No studies involved children younger than two-years old and comparisons of intervention and control groups beyond the duration of the intervention were only possible in five studies. For maternally-reported outcomes the summary effect size was 0.61 (95%CI 0.42, 0.79. Paternally-reported outcomes following Triple P intervention were smaller and did not differ significantly from the control condition (effect size 0.42 (95%CI -0.02, 0.87. The two studies involving an active control group showed no between-group differences. There was limited evidence of publication bias, but there was substantial selective reporting bias, and preferential reporting of positive results in article abstracts. Thirty-two of the 33 eligible studies were authored by Triple-P affiliated personnel. No trials were registered and only two papers contained conflict of interest

Yet, donor deferral criteria seem to be strongly based on the precautionary principle protecting safety and quality, and on supply and expense considerations. This review therefore provides an overview of the available evidence on donor exclusion criteria, as well as on their cost-effectiveness, for the most frequent reasons of donor deferral in our region. PubMed was queried to retrieve primary research studies, systematic reviews, and health technology assessments (HTAs concerning donor exclusion criteria. With a similar approach, HTAs about the different blood-banking safety interventions were included. Reasons for donor deferral were recorded via the blood bank information system of the Belgian Red Cross-Flanders. Seven systematic reviews were identified: four on donor safety (hypotension, hypertension/type 2 diabetes, epilepsy, and higher age and three on recipient safety (hemochromatosis, men who have sex with men, and endoscopy. Forty-three low-quality observational studies were included, as well as 16 HTAs: three about donor exclusion criteria and 13 cost-utility analyses about blood-banking safety interventions. In general, the available evidence for deferral reasons was of low quality, and for 60% of the top 30 reasons for excluding donors, no evidence was found. Blood banking shows its unique position as many safety measures far exceed the normally accepted cost of €50,000/quality-adjusted life-years. The historical model based on the precautionary principle and on supply and expense considerations provides adequate supplies of

    Evidence-based nursing has been highlighted and highly developed in recent decades in mainland China. Nevertheless, little is known about its overall development. To gain insights on the overall development of evidence-based nursing in the most recent 5 years and to inform future evidence-based nursing research in mainland China. Four Chinese and four English databases were searched with the search terms "evidence-based practice," "nurse or nursing," and "China or Chinese" from 2012 to 2016. Bibliometric and co-word cluster analysis were conducted with the final included publications. A total of 9036 papers published by 13 808 authors in 606 journals were included. Publication numbers were increasing. None of the top ten journals publishing evidence-based nursing papers were core nursing journals. The research hot spots on evidence-based nursing in the recent five years were cardiovascular disease, mental health, and complication prevention. However, little attention has been paid to education for evidence-based nursing. Evidence-based nursing has penetrated into various nursing branches in mainland China and become a well-recognized and relatively mature research domain. More importance should be attached to the study design, methodological, and reporting quality of evidence-based nursing projects. © 2018 John Wiley & Sons Australia, Ltd.

  4. Applications of Liquid Based Separation in Conjunction with Mass Spectrometry to the Analysis of Forensic Evidence.

    2018-03-12

    In the past few years, there has been a significant effort by the forensic science community to develop new scientific techniques for the analysis of forensic evidence. Forensic chemists have been spearheaded to develop information-rich confirmatory technologies and techniques and apply them to a broad array of forensic challenges. The purpose of these confirmatory techniques is to provide alternatives to presumptive techniques that rely on data such as color changes, pattern matching, or retention time alone, which are prone to more false positives. To this end, the application of separation techniques in conjunction with mass spectrometry has played an important role in the analysis of forensic evidence. Moreover, in the past few years the role of liquid separation techniques, such as liquid chromatography and capillary electrophoresis in conjunction with mass spectrometry, has gained significant tractions and have been applied to a wide range of chemicals, from small molecules such as drugs and explosives, to large molecules such as proteins. For example, proteomics and peptidomics have been used for identification of humans, organs, and bodily fluids. A wide range of HPLC techniques including reversed phase, hydrophilic interaction, mixed-mode, supercritical fluid, multidimensional chromatography, and nanoLC, as well as several modes of capillary electrophoresis mass spectrometry, including capillary zone electrophoresis, partial filling, full filling, and micellar electrokenetic chromatography have been applied to the analysis drugs, explosives, and questioned documents. In this article, we review recent (2015-2017) applications of liquid separation in conjunction with mass spectrometry to the analysis of forensic evidence. This article is protected by copyright.

Purported advantages over multifocal IOLs include the avoidance of haloes and no reduction in contrast sensitivity. Polymethyl methacrylate (PMMA) was the first material used in the fabrication of IOLs and has inherent ultraviolet blocking abilities. PMMA IOLs are inflexible, however, and require a larger incision for implantation compared with newer foldable silicone (hydrophobic) and acrylic (hydrophobic or hydrophilic) lenses. IOLs can be further sub-classified as being either aspheric or spheric, blue/violet filtered or non-filtered or 1- or 3-piece. METHODS OF EVIDENCE-BASED ANALYSIS: A literature search was conducted from January 2003 to January 2009 that included OVID MEDLINE, MEDLINE In-Process and Other Non-Indexed Citations, EMBASE, the Cumulative Index to Nursing & Allied Health Literature (CINAHL), The Cochrane Library, and the International Agency for Health Technology Assessment/Centre for Review and Dissemination.

    Patients and consumers are increasingly searching the Internet for medical and healthcare information. Using the criteria of evidence-based medicine the present study analyses the websites of Wikipedia and two major German statutory health insurances for content and presentation of patient information. 22 senior students of health sciences and education evaluated one topic each. In a first step, they identified the evidence for their specific question. Afterwards they used their results as reference for the evaluation of the three websites. Using a check list each student and a second researcher independently rated content and presentation of the information offered. All these websites failed to meet relevant criteria, and key information such as the presentation of probabilities of success on patient-relevant outcomes, probabilities of unwanted effects, and unbiased risk communication was missing. On average items related to the objectives of interventions, the natural course of disease and treatment options were only rated as "partially fulfilled". Overall, there were only minor differences between the three providers, except for items related to the specific nature of the websites such as disclosure of authorship, conflict of interest and support offers. In addition, the Wikipedia information tended to achieve lower comprehensibility. In conclusion, the quality of the healthcare information provided by Wikipedia and two major German statutory health insurances is comparable. They do not meet important criteria of evidence-based patient and consumer information though.

    The objective of the MAS evidence review was to conduct a systematic review of the available evidence on the safety, effectiveness, durability and cost-effectiveness of endovascular laser therapy (ELT) for the treatment of primary symptomatic varicose veins (VV). The Ontario Health Technology Advisory Committee (OHTAC) met on November 27, 2009 to review the safety, effectiveness, durability and cost-effectiveness of ELT for the treatment of primary VV based on an evidence-based review by the Medical Advisory Secretariat (MAS). CLINICAL CONDITION: VV are tortuous, twisted, or elongated veins. This can be due to existing (inherited) valve dysfunction or decreased vein elasticity (primary venous reflux) or valve damage from prior thrombotic events (secondary venous reflux). The end result is pooling of blood in the veins, increased venous pressure and subsequent vein enlargement. As a result of high venous pressure, branch vessels balloon out leading to varicosities (varicose veins). SYMPTOMS TYPICALLY AFFECT THE LOWER EXTREMITIES AND INCLUDE (BUT ARE NOT LIMITED TO): aching, swelling, throbbing, night cramps, restless legs, leg fatigue, itching and burning. Left untreated, venous reflux tends to be progressive, often leading to chronic venous insufficiency (CVI). A NUMBER OF COMPLICATIONS ARE ASSOCIATED WITH UNTREATED VENOUS REFLUX: including superficial thrombophlebitis as well as variceal rupture and haemorrhage. CVI often results in chronic skin changes referred to as stasis dermatitis. Stasis dermatitis is comprised of a spectrum of cutaneous abnormalities including edema, hyperpigmentation, eczema, lipodermatosclerosis and stasis ulceration. Ulceration represents the disease end point for severe CVI. CVI is associated with a reduced quality of life particularly in relation to pain, physical function and mobility. In severe cases, VV with ulcers, QOL has been rated to be as bad or worse as other chronic diseases such as back pain and arthritis. Lower limb VV is a

    The purpose of this project was to determine the role of corneal implants in the management of corneal thinning disease conditions. An evidence-based review was conducted to determine the safety, effectiveness and durability of corneal implants for the management of corneal thinning disorders. The evolving directions of research in this area were also reviewed. SUBJECT OF THE EVIDENCE-BASED ANALYSIS: The primary treatment objectives for corneal implants are to normalize corneal surface topography, improve contact lens tolerability, and restore visual acuity in order to delay or defer the need for corneal transplant. Implant placement is a minimally invasive procedure that is purported to be safe and effective. The procedure is also claimed to be adjustable, reversible, and both eyes can be treated at the same time. Further, implants do not limit the performance of subsequent surgical approaches or interfere with corneal transplant. The evidence for these claims is the focus of this review. The specific research questions for the evidence review were as follows: SafetyCorneal Surface Topographic Effects:Effects on corneal surface remodellingImpact of these changes on subsequent interventions, particularly corneal transplantation (penetrating keratoplasty [PKP])Visual AcuityRefractive OutcomesVISUAL QUALITY (SYMPTOMS): such as contrast vision or decreased visual symptoms (halos, fluctuating vision)Contact lens toleranceFunctional visual rehabilitation and quality of lifePatient satisfaction:Disease Process:Impact on corneal thinning processEffect on delaying or deferring the need for corneal transplantation TARGET POPULATION AND CONDITION Corneal ectasia (thinning) comprises a range of disorders involving either primary disease conditions such as keratoconus and pellucid marginal corneal degeneration or secondary iatrogenic conditions such as corneal thinning occurring after LASIK refractive surgery. The condition occurs when the normally round dome-shaped cornea

    This review examines the effectiveness of semantic feature analysis as an intervention to improve naming abilities for persons with aphasia. A systematic search of the literature identified 11 studies that met the pre-determined inclusion criteria. Two independent raters evaluated each study for methodological quality and assigned appropriate levels of evidence using the Single Case Experimental Design scale. To determine clinical effectiveness, effect sizes using Cohen's d were calculated if sufficient data were available. Alternatively, percent of non-overlapping data was calculated. Results indicated that methodologically sound research has been conducted to determine the effectiveness of semantic feature analysis for persons with aphasia using single subject research designs. When using Cohen's d, the majority of participants showed a small effect size. However, when percent of non-overlapping data was calculated, a large treatment effect was present for the majority of participants. Semantic feature analysis was an effective intervention for improving confrontational naming for the majority of participants included in the current review. Further research is warranted to examine generalization effects. Copyright © 2014 Elsevier Masson SAS. All rights reserved.

  11. Are clinical findings of systemic titanium dispersion following implantation explained by available in vitro evidence? An evidence-based analysis.

    2017-08-01

    Although the presence of titanium wear particles released into tissues is known to induce local inflammation following the therapeutic implantation of titanium devices into humans, the role that titanium ions play in adverse tissue responses has received little attention. Support that ongoing titanium ion release occurs is evidenced by the presence of ionic titanium bound to transferrin in blood, and ongoing excretion in the urine of patients with titanium devices. However, as reports documenting the presence of titanium within tissues do not distinguish between particulate and ionic forms due to technical challenges, the degree to which ionic titanium is released into tissues is unknown. To determine the potential for titanium ion release into tissues, this study evaluates available in vitro evidence relating to the release of ionic titanium under physiological conditions. This is a systematic literature review of studies reporting titanium ion release into solutions from titanium devices under conditions replicating the interstitial pH and constituents. Inclusion and exclusion criteria were defined. Of 452 articles identified, titanium ions were reported in nine media relevant to human biology in seventeen studies. Only one study, using human serum replicated both physiological pH and the concentration of constituents while reporting the presence of titanium ions. While there is insufficient information to explain the factors that contribute to the presence of titanium ions in serum of humans implanted with titanium devices, currently available information suggests that areas of future inquiry include the role of transferrin and organic acids.

    Schizophrenia is a chronic psychiatric disorder that affects about 1% of the population globally. A tremendous amount of effort has been expended in the past decade, including more than 2400 association studies, to identify genes influencing susceptibility to the disorder. However, few genes or markers have been reliably replicated. The wealth of this information calls for an integration of gene association data, evidence-based gene ranking, and follow-up replication in large sample. The objective of this study is to develop and evaluate evidence-based gene ranking methods and to examine the features of top-ranking candidate genes for schizophrenia. We proposed a gene-based approach for selecting and prioritizing candidate genes by combining odds ratios (ORs) of multiple markers in each association study and then combining ORs in multiple studies of a gene. We named it combination-combination OR method (CCOR). CCOR is similar to our recently published method, which first selects the largest OR of the markers in each study and then combines these ORs in multiple studies (i.e., selection-combination OR method, SCOR), but differs in selecting representative OR in each study. Features of top-ranking genes were examined by Gene Ontology terms and gene expression in tissues. Our evaluation suggested that the SCOR method overall outperforms the CCOR method. Using the SCOR, a list of 75 top-ranking genes was selected for schizophrenia candidate genes (SZGenes). We found that SZGenes had strong correlation with neuro-related functional terms and were highly expressed in brain-related tissues. The scientific landscape for schizophrenia genetics and other complex disease studies is expected to change dramatically in the next a few years, thus, the gene-based combined OR method is useful in candidate gene selection for follow-up association studies and in further artificial intelligence in medicine. This method for prioritization of candidate genes can be applied to other

    A quantitative weight of evidence (WoE) approach was developed to evaluate studies used for regulatory purposes, as well as those in the open literature, that report the effects of the herbicide atrazine on fish, amphibians, and reptiles. The methodology for WoE analysis incorporated a detailed assessment of the relevance of the responses observed to apical endpoints directly related to survival, growth, development, and reproduction, as well as the strength and appropriateness of the experimental methods employed. Numerical scores were assigned for strength and relevance. The means of the scores for relevance and strength were then used to summarize and weigh the evidence for atrazine contributing to ecologically significant responses in the organisms of interest. The summary was presented graphically in a two-dimensional graph which showed the distributions of all the reports for a response. Over 1290 individual responses from studies in 31 species of fish, 32 amphibians, and 8 reptiles were evaluated. Overall, the WoE showed that atrazine might affect biomarker-type responses, such as expression of genes and/or associated proteins, concentrations of hormones, and biochemical processes (e.g. induction of detoxification responses), at concentrations sometimes found in the environment. However, these effects were not translated to adverse outcomes in terms of apical endpoints. The WoE approach provided a quantitative, transparent, reproducible, and robust framework that can be used to assist the decision-making process when assessing environmental chemicals. In addition, the process allowed easy identification of uncertainty and inconsistency in observations, and thus clearly identified areas where future investigations can be best directed.

    The aim of this meta-analysis was to assess the effectiveness of evidence-based nursing (EBN) on the development of critical thinking for nursing students. A systematic literature review of original studies on randomized controlled trials was conducted. The relevant randomized controlled trials were retrieved from multiple electronic databases including Cochrane Central Register of Controlled Trials (CENTRAL), PubMed, EMBASE, Web of Science, Cumulative Index to Nursing and Allied Health (CINAHL), Chinese BioMed Database (CBM), China National Knowledge Infrastructure (CNKI), and WanFang Database. In order to make a systematic evaluation, studies were selected according to inclusion and exclusion criteria, and then according to extracted data and assessed quality. The data extraction was completed by two independent reviewers, and the methodological quality assessment was completed by another two reviewers. All of the data was analyzed by the software RevMan5.3. A total of nine studies with 1079 nursing students were chosen in this systematic literature review. The result of this meta-analysis showed that the effectiveness of evidence-based nursing was superior to that of traditional teaching on nursing students' critical thinking. The results of this meta-analysis indicate that evidence-based nursing could help nursing students to promote their development of critical thinking. More researches with higher quality and larger sample size can be analyzed in the further. Copyright © 2018. Published by Elsevier Ltd.

    Full Text Available ABSTRACT BACKGROUND Gastric cancer is the fourth most common cancer in men and the sixth among women, except for non-melanoma skin tumors, in Brazil. Epidemiological evidences reveal the multifactorial etiology of this cancer, highlighting risk factors such as: infection by the bacterium Helicobacter pylori, advanced age, smoking, chronic alcohol abuse, eating habits and genetic polymorphisms. Considering the context of genetic polymorphisms, there is the absence of the GSTM1 gene. The lack of GSTM1 function to detoxify xenobiotics and promote defense against oxidative stress leads to increased DNA damage, promoting gastric carcinogenesis. This process is multifactorial and the development of gastric cancer results from a complex interaction of these variables. OBJECTIVE The aim of this study was to investigate the association of GSTM1 null polymorphism in the pathogenesis of gastric cancer. METHODS A meta-analysis was conducted from 70 articles collected in SciELO and PubMed databases, between September 2015 and July 2016. In order to evaluate a possible association, we used the odds ratio (OR and confidence interval of 95% (CI 95%. To assess the heterogeneity of the studies was used the chi-square test. Statistical analysis was performed using the BioEstat® 5.3. RESULTS This study included 70 studies of case-control, including 28,549 individuals, which were assessed for the null polymorphism of the GSTM1 gene, and of which 11,208 (39.26% were cases and 17,341 (60.74% were controls. The final analysis showed that the presence of the GSTM1 gene acts as a protective factor against the development of gastric cancer (OR=0.788; 95%CI 0.725-0.857; P<0.0001. Positive statistical association was found in Asia (OR=0.736; 95%CI 0.670-0.809; P<0.0001 and Eurasia (OR=0.671; 95%CI 0.456-0.988; P=0.05. However, statistically significant data was not obtained in Europe (OR=1.033; 95%CI 0.873-1.222; P=0.705 and America (OR=0.866; 95%CI 0.549-1.364; P=0

    The presence of benzene in motor gasoline has been a health concern for potential increased risk of acute myelogenous leukemia and perhaps other lymphatic/hematopoietic cancers for approximately 40 years. Because of the widespread and increasing use of gasoline by consumers and the high exposure potential of occupational cohorts, a thorough understanding of this issue is important. The current study utilizes an evidence-based approach to examine whether or not the available epidemiologic studies demonstrate a strong and consistent association between occupational exposure to gasoline and lymphatic/hematopoietic cancers. Among 67 epidemiologic studies initially identified, 54 were ranked according to specific criteria relating to the relevance and robustness of each study for answering the research question. The 30 highest-ranked studies were sorted into three tiers of evidence and were analyzed for strength, specificity, consistency, temporality, dose-response trends and coherence. Meta statistics were also calculated for each general and specific lymphatic/hematopoietic cancer category with adequate data. The evidence-based analysis did not confirm any strong and consistent association between occupational exposure to gasoline and lymphatic/hematopoietic cancers based on the epidemiologic studies available to date. These epidemiologic findings, combined with the evidence showing relatively low occupational benzene vapor exposures associated with gasoline formulations during the last three decades, suggest that current motor gasoline formulations are not associated with increased lymphatic/hematopoietic cancer risks related to benzene.

    We sought to identify factors believed to facilitate or hinder evidence-based practice (EBP) implementation in public mental health service systems as a step in developing theory to be tested in future studies. Focusing across levels of an entire large public sector mental health service system for youths, we engaged participants from 6 stakeholder groups: county officials, agency directors, program managers, clinical staff, administrative staff, and consumers. Participants generated 105 unique statements identifying implementation barriers and facilitators. Participants rated each statement on importance and changeability (i.e., the degree to which each barrier or facilitator is considered changeable). Data analyses distilled statements into 14 factors or dimensions. Descriptive analyses suggest that perceptions of importance and changeability varied across stakeholder groups. Implementation of EBP is a complex process. Cross-system-level approaches are needed to bring divergent and convergent perspectives to light. Examples include agency and program directors facilitating EBP implementation by supporting staff, actively sharing information with policymakers and administrators about EBP effectiveness and fit with clients' needs and preferences, and helping clinicians to present and deliver EBPs and address consumer concerns.

    Purpose Early detection, monitoring and understanding of changes in the retina are central to the diagnosis of glaucomatous optic neuropathy, and vital to reduce visual loss from this progressive condition. The main objective of this investigation was to compare glaucoma diagnostic accuracy of commercially available optical coherence tomography (OCT) devices (Zeiss Stratus, Zeiss Cirrus, Heidelberg Spectralis and Optovue RTVue, and Topcon 3D-OCT). Patients 16,104 glaucomatous and 11,543 normal eyes reported in 150 studies. Methods Between Jan. 2017 and Feb 2017, MEDLINE®, EMBASE®, CINAHL®, Cochrane Library®, Web of Science®, and BIOSIS® were searched for studies assessing glaucoma diagnostic accuracy of the aforementioned OCT devices. Meta-analysis was performed pooling area under the receiver operating characteristic curve (AUROC) estimates for all devices, stratified by OCT type (RNFL, macula), and area imaged. Results 150 studies with 16,104 glaucomatous and 11,543 normal control eyes were included. Key findings: AUROC of glaucoma diagnosis for RNFL average for all glaucoma patients was 0.897 (0.887–0.906, n = 16,782 patient eyes), for macula ganglion cell complex (GCC) was 0.885 (0.869–0.901, n = 4841 eyes), for macula ganglion cell inner plexiform layer (GCIPL) was 0.858 (0.835–0.880, n = 4211 eyes), and for total macular thickness was 0.795 (0.754–0.834, n = 1063 eyes). Conclusion The classification capability was similar across all 5 OCT devices. More diagnostically favorable AUROCs were demonstrated in patients with increased glaucoma severity. Diagnostic accuracy of RNFL and segmented macular regions (GCIPL, GCC) scans were similar and higher than total macular thickness. This study provides a synthesis of contemporary evidence with features of robust inclusion criteria and large sample size. These findings may provide guidance to clinicians when navigating this rapidly evolving diagnostic area characterized by numerous options. PMID:29300765

    Full Text Available Numerous neuroimaging studies report abnormal regional brain activity during working memory performance in schizophrenia, but few have examined brain network integration as determined by "functional connectivity" analyses.We used independent component analysis (ICA to identify and characterize dysfunctional spatiotemporal networks in schizophrenia engaged during the different stages (encoding and recognition of a Sternberg working memory fMRI paradigm. 37 chronic schizophrenia and 54 healthy age/gender-matched participants performed a modified Sternberg Item Recognition fMRI task. Time series images preprocessed with SPM2 were analyzed using ICA. Schizophrenia patients showed relatively less engagement of several distinct "normal" encoding-related working memory networks compared to controls. These encoding networks comprised 1 left posterior parietal-left dorsal/ventrolateral prefrontal cortex, cingulate, basal ganglia, 2 right posterior parietal, right dorsolateral prefrontal cortex and 3 default mode network. In addition, the left fronto-parietal network demonstrated a load-dependent functional response during encoding. Network engagement that differed between groups during recognition comprised the posterior cingulate, cuneus and hippocampus/parahippocampus. As expected, working memory task accuracy differed between groups (p<0.0001 and was associated with degree of network engagement. Functional connectivity within all three encoding-associated functional networks correlated significantly with task accuracy, which further underscores the relevance of abnormal network integration to well-described schizophrenia working memory impairment. No network was significantly associated with task accuracy during the recognition phase.This study extends the results of numerous previous schizophrenia studies that identified isolated dysfunctional brain regions by providing evidence of disrupted schizophrenia functional connectivity using ICA within

    This article provides critical examination and comparison of the conceptual meaning and underlying assumptions of the concepts evidence-based design (EBD) and research-informed design (RID) in order to facilitate practical use and theoretical development. In recent years, EBD has experienced broad adoption, yet it has been simultaneously critiqued for rigidity and misapplication. Many practitioners are gravitating to the term RID to describe their method of integrating knowledge into the design process. However, the term RID lacks a clear definition and the blurring of terms has the potential to weaken advances made integrating research into practice. Concept analysis methods from Walker and Avant were used to define the concepts for comparison. Conceptual definitions, process descriptions, examples (i.e., model cases), and methods of evaluation are offered for EBD and RID. Although EBD and RID share similarities in meaning, the two terms are distinct. When comparing evidence based (EB) and research informed, EB is a broad base of information types (evidence) that are narrowly applied (based), while the latter references a narrow slice of information (research) that is broadly applied (informed) to create an end product of design. Much of the confusion between the use of the concepts EBD and RID arises out of differing perspectives between the way practitioners and academics understand the underlying terms. The authors hope this article serves to generate thoughtful dialogue, which is essential to the development of a discipline, and look forward to the contribution of the readership.

    Balneotherapy is appreciated as a traditional treatment modality in medicine. Hungary is rich in thermal mineral waters. Balneotherapy has been in extensive use for centuries and its effects have been studied in detail. Here, we present a systematic review and meta-analysis of clinical trials conducted with Hungarian thermal mineral waters, the findings of which have been published by Hungarian authors in English. The 122 studies identified in different databases include 18 clinical trials. Five of these evaluated the effect of hydro- and balneotherapy on chronic low back pain, four on osteoarthritis of the knee, and two on osteoarthritis of the hand. One of the remaining seven trials evaluated balneotherapy in chronic inflammatory pelvic diseases, while six studies explored its effect on various laboratory parameters. Out of the 18 studies, 9 met the predefined criteria for meta-analysis. The results confirmed the beneficial effect of balneotherapy on pain with weight bearing and at rest in patients with degenerative joint and spinal diseases. A similar effect has been found in chronic pelvic inflammatory disease. The review also revealed that balneotherapy has some beneficial effects on antioxidant status, and on metabolic and inflammatory parameters. Based on the results, we conclude that balneotherapy with Hungarian thermal-mineral waters is an effective remedy for lower back pain, as well as for knee and hand osteoarthritis.

  6. Continuity of care to optimize chronic disease management in the community setting: an evidence-based analysis.

    Science.gov (United States)

    2013-01-01

    This evidence-based analysis reviews relational and management continuity of care. Relational continuity refers to the duration and quality of the relationship between the care provider and the patient. Management continuity ensures that patients receive coherent, complementary, and timely care. There are 4 components of continuity of care: duration, density, dispersion, and sequence. The objective of this evidence-based analysis was to determine if continuity of care is associated with decreased health resource utilization, improved patient outcomes, and patient satisfaction. MEDLINE, EMBASE, CINAHL, the Cochrane Library, and the Centre for Reviews and Dissemination database were searched for studies on continuity of care and chronic disease published from January 2002 until December 2011. Systematic reviews, randomized controlled trials, and observational studies were eligible if they assessed continuity of care in adults and reported health resource utilization, patient outcomes, or patient satisfaction. Eight systematic reviews and 13 observational studies were identified. The reviews concluded that there is an association between continuity of care and outcomes; however, the literature base is weak. The observational studies found that higher continuity of care was frequently associated with fewer hospitalizations and emergency department visits. Three systematic reviews reported that higher continuity of care is associated with improved patient satisfaction, especially among patients with chronic conditions. Most of the studies were retrospective cross-sectional studies of large administrative databases. The databases do not capture information on trust and confidence in the provider, which is a critical component of relational continuity of care. The definitions for the selection of patients from the databases varied across studies. There is low quality evidence that: Higher continuity of care is associated with decreased health service utilization.There is

    2014-01-01

    The increasing prevalence of diabetes in Ontario means that there will be growing demand for hemoglobin A1c (HbA1c) testing to monitor glycemic control for the management of this chronic disease. Testing HbA1c where patients receive their diabetes care may improve system efficiency if the results from point-of-care HbA1c testing are comparable to those from laboratory HbA1c measurements. To review the correlation between point-of-care HbA1c testing and laboratory HbA1c measurement in patients with diabetes in clinical settings. The literature search included studies published between January 2003 and June 2013. Search terms included glycohemoglobin, hemoglobin A1c, point of care, and diabetes. Studies were included if participants had diabetes; if they compared point-of-care HbA1c devices (licensed by Health Canada and available in Canada) with laboratory HbA1c measurement (reference method); if they performed point-of-care HbA1c testing using capillary blood samples (finger pricks) and laboratory HbA1c measurement using venous blood samples within 7 days; and if they reported a correlation coefficient between point-of-care HbA1c and laboratory HbA1c results. Three point-of-care HbA1c devices were reviewed in this analysis: Bayer's A1cNow+, Bio-Rad's In2it, and Siemens' DCA Vantage. Five observational studies met the inclusion criteria. The pooled results showed a positive correlation between point-of-care HbA1c testing and laboratory HbA1c measurement (correlation coefficient, 0.967; 95% confidence interval, 0.960-0.973). Outcomes were limited to the correlation coefficient, as this was a commonly reported measure of analytical performance in the literature. Results should be interpreted with caution due to risk of bias related to selection of participants, reference standards, and the multiple steps involved in POC HbA1c testing. Moderate quality evidence showed a positive correlation between point-of-care HbA1c testing and laboratory HbA1c measurement. Five

    to evaluate arterial flow in blood vessels. The value of the ABI can provide an assessment of the severity of the disease. Other non invasive imaging techniques include: Computed Tomography (CT) and Magnetic Resonance Angiography (MRA). Definitive diagnosis of PAD can be made by an invasive catheter based angiography procedure which shows the roadmap of the arteries, depicting the exact location and length of the stenosis / occlusion. Angiography is the standard method against which all other imaging procedures are compared for accuracy. More than 70% of the patients diagnosed with PAD remain stable or improve with conservative management of pharmacologic agents and life style modifications. Significant PAD symptoms are well known to negatively influence an individual quality of life. For those who do not improve, revascularization methods either invasive or non-invasive can be used to restore peripheral circulation. TECHNOLOGY UNDER REVIEW: A Stent is a wire mesh "scaffold" that is permanently implanted in the artery to keep the artery open and can be combined with angioplasty to treat PAD. There are two types of stents: i) balloon-expandable and ii) self expandable stents and are available in varying length. The former uses an angioplasty balloon to expand and set the stent within the arterial segment. Recently, drug-eluting stents have been developed and these types of stents release small amounts of medication intended to reduce neointimal hyperplasia, which can cause re-stenosis at the stent site. Endovascular stenting avoids the problem of early elastic recoil, residual stenosis and flow limiting dissection after balloon angioplasty. In individuals with PAD of the lower extremities (superficial femoral artery, infra-popliteal, crural and iliac artery stenosis or occlusion), is primary stenting more effective than percutaneous transluminal angioplasty (PTA) in improving patency?In individuals with PAD of the lower extremities (superficial femoral artery, infra

    Full Text Available This paper tests technical and scale efficiency of 20 Kazakh banks using annualdata on three inputs (interest expenses, non-interestexpenses and deposits andthree outputs (interest income, non-interest income and loans over the period2007-2011. Two input-oriented data envelopment analysis models of Charnes etal (1978 and Banker et al(1984, which are based on constant return to scale andvariable return to scale respectively, areused to evaluate technical efficiency,whereas scale efficiency is computed bydividing the former efficiency ratio bythe latter one. The resultsobtained show that the average efficiency ratios ofindividual banks under constant and variable returns toscale range from 0.88 and1.00 to 0.93 and 1.00 respectively, whereas those of all banks between 0.95 and0.98 respectively. Only are the fivebanks (ATFB, Citibank, HSBC bank,KazInvest bank and Exim bank the mostefficient banks in Kazakhstan, sincetheir efficiency ratios have been consistently equal to unity, implying that thesebanks operate at their optimal levels. The efficiency scores of the remaining 15banks range from 0.88 to 0.99, and as suchthe majority of these banks do notseem to operate far more below their optimal level. The results indicate that theperformance of the Kazakh banks deteriorated substantially during the globalfinancial crisis of 2008 because theCRS ratio dropped from 0.65 in 2007 to 0.50in 2008 and to 0.40 in 2009. The results alsoconfirm that most of the foreignbanks perform relatively better than domestic banks.

    2010-01-01

    This paper extends the work in Tabak and Cajueiro (Are the crude oil markets becoming weakly efficient over time, Energy Economics 29 (2007) 28-36) and Alvarez-Ramirez et al. (Short-term predictability of crude oil markets: a detrended fluctuation analysis approach, Energy Economics 30 (2008) 2645-2656). In this paper, we test for the efficiency of WTI crude oil market through observing the dynamic of local Hurst exponents employing the method of rolling window based on multiscale detrended fluctuation analysis. Empirical results show that short-term, medium-term and long-term behaviors were generally turning into efficient behavior over time. However, in this way, the results also show that the market did not evolve along stable conditions for long times. Multiscale analysis is also implemented based on multifractal detrended fluctuation analysis. We found that the small fluctuations of WTI crude oil market were persistent; however, the large fluctuations had high instability, both in the short- and long-terms. Our discussion is also extended by incorporating arguments from the crude oil market structure for explaining the different correlation dynamics. (author)

  14. Evidence-based analysis of prophylactic treatment of asymptomatic retinal breaks and lattice degeneration.

    2000-01-01

    To assess the quality of information in the literature regarding the benefits of prophylactic treatment of asymptomatic retinal tears and lattice degeneration. Asymptomatic retinal breaks occur in approximately 7% of patients over age 40, and lattice degeneration is present in approximately 8% of the general population. Because retinal breaks cause retinal detachment and lattice degeneration is associated with approximately 30% of retinal detachments, prophylactic treatment of these lesions has sometimes been recommended. A panel of vitreoretinal experts performed a literature review of all publications regarding prevention of retinal detachment that have been published in English. These articles were then used to prepare recommendations for patient care in an American Academy of Ophthalmology Preferred Practice Pattern (PPP). Each recommendation was rated according to: (1) its importance in the care process and (2) the strength of evidence supporting the given recommendation. Most recommendations were rated as A (most important to patient care). Only a single publication was graded as I (providing strong evidence in support of a recommendation), and this was not a prospective trial. Of the few publications rated as II (substantial evidence), most were studies documenting a lack of treatment benefit. Because of an absence of level I and level II studies in the literature, level III (consensus of expert opinion) was the basis for most recommendations in the PPP. The current literature regarding prevention of retinal detachment does not provide sufficient information to support strongly prophylactic treatment of lesions other than symptomatic flap tears. Prospective randomized trials of prophylactic therapy are indicated. Eyes highly predisposed to retinal detachment should be considered for such studies.

    2015-01-01

    Prostate cancer (PC) is the most commonly diagnosed non-cutaneous cancer in men and their second or third leading cause of cancer death. Prostate-specific antigen (PSA) testing for PC has been in common practice for more than 20 years. A systematic review of the scientific literature was conducted to determine the effectiveness of PSA-based population screening programs for PC to inform policy decisions in a publicly funded health care system. A systematic review of bibliographic databases was performed for systematic reviews or randomized controlled trials (RCT) of PSA-based population screening programs for PC. A broad search strategy was employed to identify studies reporting on key outcomes of PC mortality and all-cause mortality. The search identified 5 systematic reviews and 6 RCTs. None of the systematic reviews found a statistically significant reduction in relative risk (RR) of PC mortality or overall mortality with PSA-based screening. PC mortality reductions were found to vary by country, by screening program, and by age of men at study entry. The European Randomized Study of Screening for Prostate Cancer found a statistically significant reduction in RR in PC mortality at 11-year follow-up (0.79; 95% CI, 0.67-0.92), although the absolute risk reduction was small (1.0/10,000 person-years). However, the primary treatment for PCs differed significantly between countries and between trial arms. The American Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial (PLCO) found a statistically non-significant increase in RR for PC mortality with 13-year follow-up (1.09; 95% CI, 0.87-1.36). The degree of opportunistic screening in the control arm of the PLCO trial, however, was high. None of the RCTs found a reduction in all-cause mortality and all found a statistically significant increase in the detection of mainly low-risk, organ-confined PCs in the screening arm. There was no evidence of a PC mortality reduction in the American PLCO trial, which

  19. Clinical relevance of oxidative stress and sperm chromatin damage in male infertility: an evidence based analysis

    Directory of Open Access Journals (Sweden)

    2007-10-01

    Full Text Available Oxidative stress (OS in the reproductive tract is now a real entity and concern due to the potential harmful effects of high levels of reactive oxygen species (ROS on sperm number, motility, quality, and function including damage to sperm nuclear DNA. Evaluation of OS related damage to non-functional sperm is highly relevant as intracytoplasmic sperm injection (ICSI technique, an effective therapy for severe male factor infertility, bypasses the majority of reproductive tract deficiencies. Despite the controversial findings in the existing literature, there is now enough evidence to show that sperm DNA damage is detrimental to reproductive outcomes. In addition, spermatozoa of infertile men are suggested to carry more DNA damage than do the spermatozoa from fertile men. Besides impairment of fertility such damage is likely to increase the transmission of genetic diseases during the assisted reproductive procedures. Standardization of protocols to assess reactive oxygen species and DNA damage is very important in introducing these tests in such clinical practice. Thus evaluation of seminal ROS levels and extent of sperm DNA damage especially in an infertile male may help develop new therapeutic strategies and improve success of assisted reproductive techniques (ART.

    The aim of this study was to examine the relative efficacy of evidence-based treatments (EBTs) versus treatment-as-usual (TAU) in routine care for anxiety and depression in adults. A computerized search of studies that directly compared an EBT with a TAU was conducted. Meta-analytic methods were used to estimate effectiveness of EBTs relative to TAU and to model how various confounding variables impacted the results of this comparative research. A total of 14 studies were included in the final meta-analysis. There was significant heterogeneity in the TAU conditions, which ranged from unknown and/or minimal mental health treatment to psychotherapeutic interventions provided by trained professionals. Although the effect for EBT vs. TAU was significantly greater than zero, the effect for EBT vs. TAUs that were psychotherapeutic interventions was not statistically different from zero. Heterogeneity of TAU conditions in this meta-analysis highlight the importance of clarifying the research questions being asked when investigating and drawing conclusions from EBT-TAU comparisons. Researchers need to clarify if they are comparing an EBT to psychotherapeutic services in routine care or to minimal mental health services. Extant research on EBT versus TAU reveals that there is insufficient evidence to recommend the transportation of EBTs for anxiety and depression to routine care, particularly when the routine care involves psychotherapeutic services.

    2010-05-01

    The phylogeny and the biogeographical history of the genus Vanilla was investigated using four chloroplastic genes (psbB, psbC; psaB and rbcL), on 47 accessions of Vanilla chosen from the ex situ CIRAD collection maintained in Reunion Island and additional sequences from GenBank. Bayesian methods provided a fairly well supported reconstruction of the phylogeny of the Vanilloideae sub-family and more particularly of the genus Vanilla. Three major phylogenetic groups in the genus Vanilla were differentiated, which is in disagreement with the actual classification in two sections (Foliosae and Aphyllae) based on morphological traits. Recent Bayesian relaxed molecular clock methods allowed to test the two main hypotheses of the phylogeography of the genus Vanilla. Early radiation of the Vanilla genus and diversification by vicariance consecutive to the break-up of Gondwana, 95 million years ago (Mya), was incompatible with the admitted age of origin of Angiosperm. Based on the Vanilloideae age recently estimated to 71 million years ago (Mya), we conclude that the genus Vanilla would have appeared approximately 34 Mya in South America, when continents were already separated. Nevertheless, whatever the two extreme scenarios tested, at least three long distance migration events are needed to explain the present distribution of Vanilla species in tropical areas. These transoceanic dispersions could have occurred via transoceanic passageway such as the Rio Grande Ridge and the involvement of floating vegetation mats and migratory birds.

    Pron, G; Ieraci, L; Kaulback, K

    2011-01-01

    The main objectives for this evidence-based analysis were to determine the safety and effectiveness of photochemical corneal collagen cross-linking with riboflavin (vitamin B(2)) and ultraviolet-A radiation, referred to as CXL, for the management of corneal thinning disease conditions. The comparative safety and effectiveness of corneal cross-linking with other minimally invasive treatments such as intrastromal corneal rings was also reviewed. The Medical Advisory Secretariat (MAS) evidence-based analysis was performed to support public financing decisions. SUBJECT OF THE EVIDENCE-BASED ANALYSIS: The primary treatment objective for corneal cross-linking is to increase the strength of the corneal stroma, thereby stabilizing the underlying disease process. At the present time, it is the only procedure that treats the underlying disease condition. The proposed advantages for corneal cross-linking are that the procedure is minimally invasive, safe and effective, and it can potentially delay or defer the need for a corneal transplant. In addition, corneal cross-linking does not adversely affect subsequent surgical approaches, if they are necessary, or interfere with corneal transplants. The evidence for these claims for corneal cross-linking in the management of corneal thinning disorders such as keratoconus will be the focus of this review. The specific research questions for the evidence review were as follows: TECHNICAL: How technically demanding is corneal cross-linking and what are the operative risks? What is known about the broader safety profile of corneal cross-linking?Effectiveness - Corneal Surface Topographic Affects:What are the corneal surface remodeling effects of corneal cross-linking?Do these changes interfere with subsequent interventions, particularly corneal transplant known as penetrating keratoplasty (PKP)?Effectiveness -Visual Acuity:What impacts does the remodeling have on visual acuity?Are these impacts predictable, stable, adjustable and

    As part of the process of creating an update of the clinical practice guidelines for developmental coordination disorder (DCD) (Blank, Smits-Engelsman, Polatajko, & Wilson, 2012), a systematic review of intervention studies, published since the last guidelines statement was conducted. The aim of this study was to 1) systematically review the evidence published from January 2012 to February 2017 regarding the effectiveness of motor based interventions in individuals with DCD, 2) quantify treatment effects using a meta-analysis, 3) examine the available information on different aspects of delivery including use of group intervention, duration and frequency of therapy, and 4) identify gaps in the literature and make recommendations for future intervention research. An electronic search of 5 databases (PubMed, Embase, Pedro, Scopus and Cochrane) was conducted for studies that evaluated motor-based interventions to improve performance for individuals with DCD. Thirty studies covering 25 datasets were included, 19 of which provided outcomes on standardized measures of motor performance. The overall effect size (Cohen's d) across intervention studies was large (1.06), but the range was wide: for 11 interventions, the observed effect was large (>0.80), in eight studies moderate (>0.50), and in five it was small or negligible (Positive benefits were evident for activity-oriented approaches, body function-oriented combined with activities, active video games, and small group programs. Results showed that activity-oriented and body function oriented interventions can have a positive effect on motor function and skills. However, given the varied methodological quality and the large confidence intervals of some studies, the results should be interpreted with caution. Copyright © 2018 Elsevier Ltd.

Methods - This paper critically analyses three evidence based research projects conducted at Bond University Library. Each project combined a range of research methods including surveys, literature reviews and the analysis of internal performance data to find solutions to problems in library service delivery. The first research project investigated library opening hours and the feasability of twenty-four hour opening. Another project reseached questions about the management of a collection of feature films on DVD and video. The thrd project investigated issues surrounding the teaching of EndNote to undergarduate students. Results - Despite some deficiencies in the methodologies used, each evidence based research project had positive outcomes. One of the highlights asn an essential feature of the process at Bond University Library was the involvement of stakeholders. The ability to build consensus and agree action plans with stakeholders was an important outcome of that process. Conclusion - Drawing on the experience of these research projects, the paper illustrates the benefits of evidence based information practice to stimulate innovation and improve library services. Librarians, like most professionals, need to continue to develop the skills and a culture to effectively carry out evidence based practice.

    1) based on moderate quality evidence, with consistent results among a subgroup analysis of patients with diabetes based on low quality evidence. Model 2 showed an overall improvement in appropriate process measures, disease-specific measures, and patient satisfaction based on low to moderate quality evidence. There was low quality evidence that nurses working under Model 2 may reduce hospitalizations for patients with coronary artery disease. The specific role of the nurse in supplementing or substituting physician care was unclear, making it difficult to determine the impact on efficiency. Nurses with additional skills, training, or scope of practice may help improve the primary care of patients with chronic diseases. This review found that specialized nurses working on their own could achieve health outcomes that were similar to those of doctors. It also found that specialized nurses who worked with doctors could reduce hospital visits and improve certain patient outcomes related to diabetes, coronary artery disease, or heart failure. Patients who had nurse-led care were more satisfied and tended to receive more tests and medications. It is unclear whether specialized nurses improve quality of life or doctor workload.

    The objective of this manuscript is to provide an evidence-based analysis of the current status and future perspectives of robotic laparoendoscopic single-site surgery (R-LESS). A PubMed search has been performed for all relevant urological literature regarding natural orifice transluminal endoscopic surgery (NOTES) and laparoendoscopic single-site surgery (LESS). All clinical and investigative reports for robotic LESS and NOTES procedures in the urological literature have been considered. A significant number of clinical urological procedures have been successfully completed utilizing R-LESS procedures. The available experience is limited to referral centers, where the case volume is sufficient to help overcome the challenges and learning curve of LESS surgery. The robotic interface remains the best fit for LESS procedures but its mode of use continues to evolve in attempts to improve surgical technique. We stand today at the dawn of R-LESS surgery, but this approach may well become the standard of care in the near future. Further technological development is needed to allow widespread adoption of the technique.

    This study aims to offer evidence-based feedback about the emotional challenges of cancer in South Africa. The action research photovoice methodology was used to capture accounts of cancer-related challenges via 316 face-to-face interviews with cancer patients and family members (n = 286), and oncology support and medical staff (n = 30). The photovoice contributions constituted qualitative data that were analysed according to inductive thematic analysis whereby nine themes of cancer challenges were identified and photovoice images were descriptively summarised from a phenomenological perspective. The emotional challenges theme was the most commonly reported of these themes, and is the focus of this paper. The findings of this study highlighted widespread emotional distress, anxiety, loss, poverty, physical challenges, traumatic impact of a cancer diagnosis, cancer stigma and low patient empowerment in the medical setting. Four main causes of patient emotional isolation in advanced stages of cancer are also identified, and this extends current understanding and offers new direction for clinical management. Recommendations from these findings include the need for the development and inclusion of psychosocial oncology services, best-practice standards of care, distress screening, patient empowerment and the prioritising of training and support for oncology staff in the South African health-care setting.

  15. Evidence-based management reconsidered.

    Reports of medical mistakes have splashed across newspapers and magazines in the United States. At the same time, instances of overuse, underuse, and misuse of management tactics and strategies receive far less attention. The sense of urgency associated with improving the quality of medical care does not exist with respect to improving the quality of management decision making. A more evidence-based approach would improve the competence of the decision-makers and their motivation to use more scientific methods when making a decision. The authors of this article consider a study of 68 U.S. health services managers that found a low level of evidence-based management behaviors. From the findings, four strategies are suggested to increase health systems managers' use of research evidence to improve decision making: focusing evidence-based decision making on strategically important issues, developing committees and other structures to diffuse management research throughout the organization, building a management culture that values research, and training managers in the competencies required to apply research evidence to health services management decisions. To aid the manager in understanding and applying an evidenced-based approach to decision making, the article provides practical tools, techniques, and resources for immediate use.

    The aim of this study is to determine the clinical rates of the demonstration of the inframammary angle (IMA) on the mediolateral oblique (MLO) view of the breast on digital mammograms and to compare the outcomes with current accreditation standards for compliance. Relationships between the IMA, age, the posterior nipple line (PNL) and compressed breast thickness will be identified and the study outcomes validated using appropriate analyses of inter-reader and inter-rater reliability and variability. Differences in left versus right data were also investigated. A quantitative retrospective study of 2270 randomly selected paired digital mammograms performed by BreastScreen NSW was undertaken. Data was collected by direct measurement and visual analysis. Intra-class correlation analyses were used to evaluate inter- and intra-rater reliability. The IMA was demonstrated on 52.4% of individual and 42.6% of paired mammograms. A linear relationship was found between the posterior nipple line (PNL) and age (p-value PNL was predicted to increase by 0.48 mm for every one year increment in age. The odds of demonstrating the IMA reduced by 2% for every one year increase in age (p-value = 0.001); are 0.4% higher for every 1 mm increase in PNL (p-value = 0.001) and 1.6% lower for every 1 mm increase in compressed breast thickness, (p-valuePNL while there was 100% agreement for the demonstration of the IMA. Analysis of the demonstration of the IMA indicates clinically achievable rates (42.6%) well below that required for compliance (50%-75%) to known worldwide accreditation standards for screening mammography. These standards should be aligned to the reported evidence base. Visualisation of the IMA is impacted negatively by increasing age and compressed breast thickness but positively by breast size (PNL).

    Those in nursing have been charged with practicing to the full extent of their education and training by the Institute of Medicine. Therefore, evidence-based practice (EBP) has never been more important to nursing than in the current healthcare environment. Frequently the burden of EBP is the responsibility of the bedside practitioner, but has been found to be a process that requires leadership and organizational support. A key underlying component of a strong EBP environment includes effective communications and collaboration among staff and nursing leadership. Developing measurement tools that examine the milieu and nursing leadership in which the staff nurse practices is an important component of understanding the factors that support or hinder EBP. The aim of this study is to report on the development and analysis of two new scales designed to explore leadership and organizational support for EBP. The EBP Nursing Leadership Scale (10 items) examines the staff nurses perception of support provided by the nurse manager for EBP, and the EBP Work Environment Scale (8 items) examines organizational support for EBP. Staff nurses who worked at least .5 FTE in direct patient care, from two inner city hospitals (n = 422) completed the scales. The scales were evaluated for internal consistency reliability with the Cronbach alpha technique, content validity using a panel of experts, and construct validity by The content validity index computed from expert rankings was .78 to 1.0 with an average of.96. Cronbach's alpha was .96 (n = 422) for the EBP Nursing Leadership Scale and .86 (n = 422) for the EBP Work Environment Scale. Factor analysis confirmed that each scale measured a unidimensional construct (p Leadership Scale and the EBP Work Environment Scale are psychometrically sound instruments to examine organizational influences on EBP. © 2014 Sigma Theta Tau International.

    2017-04-01

    The aims of this study were to identify characteristics of the top-cited articles in problem-based learning (PBL) and assess the quality of evidence provided by these articles. The most frequently cited articles on PBL were searched in April 2015 in the Science Citation Index Expanded database (List A) and Google Scholar database (List B). Eligible articles identified were reviewed for key characteristics. The Oxford Centre for Evidence-Based Medicine guidelines were used in assessing the level of evidence. The number of citations varied (62 to 923 on List A and 218 to 2,859 on List B). Countries that contributed the majority of articles in both lists were the United States, Netherlands, United Kingdom, and Canada. No significant correlations were found between number of citations and number of years since published (p=0.451), number of authors (p=0.144), females in authorship (p=0.189), non-medical authors (p=0.869), number of institutions (p=0.452), and number of grants (p=0.143), but a strong correlation was found with number of countries involved (p=0.007). Application of the Oxford hierarchy of evidence showed that 36 articles were at levels 4 and 5 of evidence. This study found that research articles represented approximately one-third of PBL articles assessed and reported mainly on questionnaire-based studies. The most highly cited articles occupied top-ranking positions in the journals in which they were published. The lower level of evidence observed in most top-cited articles may reflect the significance of innovative ideas or content of these articles. These findings have implications for dental educators and dental researchers.

    2017-01-01

    In recent years there has been increasing emphasis on evidence-based practice in psychology (EBPP), and as is true in most health care professions, the primary focus of EBPP has been on treatment. Comparatively little attention has been devoted to applying the principles of EBPP to psychological assessment, despite the fact that assessment plays a central role in myriad domains of empirical and applied psychology (e.g., research, forensics, behavioral health, risk management, diagnosis and classification in mental health settings, documentation of neuropsychological impairment and recovery, personnel selection and placement in organizational contexts). This article outlines the central elements of evidence-based psychological assessment (EBPA), using the American Psychological Association's tripartite definition of EBPP as integration of the best available research with clinical expertise in the context of patient characteristics, culture, and preferences. After discussing strategies for conceptualizing and operationalizing evidence-based testing and evidence-based assessment, 6 core skills and 3 meta-skills that underlie proficiency in psychological assessment are described. The integration of patient characteristics, culture, and preferences is discussed in terms of the complex interaction of patient and assessor identities and values throughout the assessment process. A preliminary framework for implementing EBPA is offered, and avenues for continued refinement and growth are described.

This study aimed to develop a composite tool to measure the organisational context for evidence-based practice (EBP in healthcare. Methods A structured search of the major healthcare and management databases for measurement tools from four domains: research utilisation (RU, research activity (RA, knowledge management (KM, and organisational learning (OL. Included studies were reports of the development or use of measurement tools that included organisational factors. Tools were appraised for face and content validity, plus development and testing methods. Measurement tool items were extracted, merged across the four domains, and categorised within a constructed framework describing the absorptive and receptive capacities of organisations. Results Thirty measurement tools were identified and appraised. Eighteen tools from the four domains were selected for item extraction and analysis. The constructed framework consists of seven categories relating to three core organisational attributes of vision, leadership, and a learning culture, and four stages of knowledge need, acquisition of new knowledge, knowledge sharing, and knowledge use. Measurement tools from RA or RU domains had more items relating to the categories of leadership, and acquisition of new knowledge; while tools from KM or learning organisation domains had more items relating to vision, learning culture, knowledge need, and knowledge sharing. There was equal emphasis on knowledge use in the different domains. Conclusion If the translation of evidence into knowledge is viewed as socially mediated, tools to measure the organisational context of EBP in healthcare could be enhanced by consideration of related concepts from the organisational

  4. Is Project Based Learning More Effective than Direct Instruction in School Science Classrooms? An Analysis of the Empirical Research Evidence

    Science.gov (United States)

    Dann, Clifford

    An increasingly loud call by parents, school administrators, teachers, and even business leaders for "authentic learning", emphasizing both group-work and problem solving, has led to growing enthusiasm for inquiry-based learning over the past decade. Although "inquiry" can be defined in many ways, a curriculum called "project-based learning" has recently emerged as the inquiry practice-of-choice with roots in the educational constructivism that emerged in the mid-twentieth century. Often, project-based learning is framed as an alternative instructional strategy to direct instruction for maximizing student content knowledge. This study investigates the empirical evidence for such a comparison while also evaluating the overall quality of the available studies in the light of accepted standards for educational research. Specifically, this thesis investigates what the body of quantitative research says about the efficacy of project-based learning vs. direct instruction when considering student acquisition of content knowledge in science classrooms. Further, existing limitations of the research pertaining to project based learning and secondary school education are explored. The thesis concludes with a discussion of where and how we should focus our empirical efforts in the future. The research revealed that the available empirical research contains flaws in both design and instrumentation. In particular, randomization is poor amongst all the studies considered. The empirical evidence indicates that project-based learning curricula improved student content knowledge but that, while the results were statistically significant, increases in raw test scores were marginal.

    To estimate the association of implementation of evidence-based bundles with surgical site infection rates after cesarean delivery. We searched MEDLINE through PubMed, EMBASE, Scopus, the Cochrane Database of Systematic Reviews, Google Scholar, and ClinicalTrials.gov. We searched electronic databases for randomized controlled trials and observational studies comparing evidence-based infection prevention bundles for cesarean delivery, defined as implementation of three or more processes proven to prevent surgical site infection such as chlorhexidine skin preparation, antibiotic prophylaxis, and hair clipping, with usual care. The primary outcome was overall surgical site infection, defined using Centers for Disease Control and Prevention's National Healthcare Safety Network criteria. Secondary outcomes were superficial or deep surgical site infection and endometritis. Quality of studies and heterogeneity were assessed using validated measures. Pooled relative risks (RRs) with 95% CIs were calculated using random-effects models. Numbers needed to treat were estimated for outcomes with significant reduction. We found no randomized controlled trials. Fourteen preintervention and postintervention studies met inclusion criteria. Eight were full-text articles, and six were published abstracts. Quality of most of the primary studies was adequate with regard to the intervention, but modest in terms of implementation. The rate of surgical site infection was significantly lower after implementing an evidence-based bundle (14 studies: pooled rates 6.2% baseline compared with 2.0% intervention, pooled RR 0.33, 95% CI 0.25-0.43, number needed to treat=24). Evidence-based bundles were also associated with a lower rate of superficial or deep surgical site infection (six studies: pooled rate 5.9% baseline compared with 1.1% intervention, pooled RR 0.19, 95% CI 0.12-0.32, number needed to treat=21). The rate of endometritis was low at baseline and not significantly different after

    Various interventions are used in clinical practice to address insecure or disorganized attachment patterns and attachment disorders. The most common of these are parenting interventions, but not all have a robust empirical evidence base. We undertook a systematic review of randomized trials comparing a parenting intervention with a control, where these used a validated attachment instrument, in order to evaluate the clinical and cost-effectiveness of interventions aiming to improve attachment in children with severe attachment problems (mean age parenting interventions included in our systematic review that were clinically effective in promoting secure attachment. For completeness, we also briefly discuss other interventions without randomized controlled trial evidence, identified in Patient Public Involvement workshops and expert groups at the point our review was completed as being used or recommended. We outline the key implications of our findings for clinical practice and future research.

    2000-01-01

    This paper discusses the challenges of finding evidence needed to implement Evidence-Based Librarianship (EBL). Focusing first on database coverage for three health sciences librarianship journals, the article examines the information contents of different databases. Strategies are needed to search for relevant evidence in the library literature via these databases, and the problems associated with searching the grey literature of librarianship. Database coverage, plausible search strategies, and the grey literature of library science all pose challenges to finding the needed research evidence for practicing EBL. Health sciences librarians need to ensure that systems are designed that can track and provide access to needed research evidence to support Evidence-Based Librarianship (EBL).

    2005-01-01

    health technology assessments for urge incontinence, urgency-frequency, and urinary retention included (RCTs (level 2) as their primary source of evidence for their conclusions. The assessment of fecal incontinence based its conclusions on evidence from case series (level 4). Because there was level 2 data available for the use of SNS in patients with urinary conditions, the Medical Advisory Secretariat chose to review thoroughly the RCTs included in the assessments and search for publications since the assessments were released. However, for the health technology assessment for fecal incontinence, which contained only level 4 evidence, the Medical Advisory Secretariat searched for studies on SNS and fecal incontinence that were published since that assessment was released. URGE INCONTINENCE: Two RCTs were identified that compared SNS to no treatment in patients with refractory urge incontinence. Both RCTs reported significant improvements (> 50% improvement in voiding function) in the SNS group for number of incontinence episodes per day, number of pads used per day, and severity of incontinence episodes. URGENCY-FREQUENCY (WITH OR WITHOUT CHRONIC PELVIC PAIN): One RCT was identified that compared SNS to no treatment in patients with refractory urgency-frequency. The RCT reported significant improvements in urgency-frequency symptoms in the SNS group (average volume per void, detrusor pressure). In addition to the RCT, 1 retrospective review and 2 prospective case series were identified that measured pelvic pain associated with urgency-frequency in patients who underwent SNS. All 3 studies reported a significant decrease in pain at median follow-up. URINARY RETENTION: One RCT was identified that compared SNS to no treatment in patients with refractory urinary retention. The RCT reported significant improvements in urinary retention in the SNS group compared to the control group for number of catheterizations required and number of voids per day. In addition to this RCT

    Full Text Available Significant benefits can be derived by heart failure patients from exercise training. This paper provides an evidence-based assessment of expected clinical benefits of exercise training for heart failure patients. Meta-analyses and randomized, controlled trials of exercise training in heart failure patients were reviewed from a search of PubMed, Cochrane Controlled Trial Registry (CCTR, CINAHL, and EMBASE. Exercise training improves functional capacity, quality of life, hospitalization, and systolic and diastolic function in heart failure patients. Heart failure patients with preserved systolic function (HFnEF participating in exercise training studies are more likely to be women and are 5–7 years older than their systolic heart failure (CHF counterparts. All patients exhibit low functional capacities, although in HFnEF patients this may be age related, therefore subtle differences in exercise prescriptions are required. Published works report that exercise training is beneficial for heart failure patients with and without systolic dysfunction.

    2014-01-01

    Full Text Available A method based on grey relational analysis and D-S theory of evidence is proposed for fuzzy soft sets in decision making. Firstly, grey relational analysis is used to calculate grey mean relational degrees and determine uncertain degrees of parameters. Then based on uncertain degrees, suitable mass functions of different independent alternatives with different parameters can be constructed. Next, D-S rule of evidence combination is applied to aggregate these alternatives into a collective alternative. Finally, these alternatives are ranked and the best alternative(s are obtained. Moreover, the effectiveness and feasibility of this method are demonstrated by comparing with the mean potentiality approach and giving an application to medical diagnosis.

    Functional decline is a primary risk factor for institutionalization and mortality among older adults. Although community-based fall risk reduction programs have been widely disseminated, little is known about their impact on gait speed, a key indicator of functional performance. Changes in functional performance between baseline and post-intervention were examined by means of timed up and go (TUG), a standardized functional assessment test administered to participants enrolled in A Matter of Balance/Volunteer Lay Leader (AMOB/VLL) model, an evidence-based fall risk reduction program. This study included 71 participants enrolled in an AMOB/VLL program in the Brazos Valley and South Plain regions of Texas. Paired t-tests were employed to assess program effects on gait speed at baseline and post-intervention for all participants and by subgroups of age, sex, living status, delivery sites, and self-rated health. The Bonferroni correction was applied to adjust inflated Type I error rate associated with performing multiple t-tests, for which p-values fall risk reduction programs can improve gait speed for older adults. More translational research is needed to understand factors related to the effectiveness of fall risk reduction programs in various populations and settings.

    Many occupational therapy practitioners consider evidence-based practice (EBP) to be the means by which occupational therapy can prove the validity of its services and thus support the legitimacy of our profession. The unquestioned acceptance of EBP as the way to establish credibility concerns me; unchallenged acceptance of any idea concerns me. Do practitioners accept EBP as the paradigm for guiding occupational therapy practice and research solely because it is presented as what we must do? I believe that practitioners must examine the implications for our profession of accepting EBP without question. In this article, I review EBP, present criticisms and concerns voiced by other professions and, finally, examine the implications of adopting an EBP perspective that replaces theory-directed practice.

    Since the term "evidence-based medicine" (EBM) first appeared in the scientific literature in 1991, the concept has had considerable influence in many parts of the world. Most professional societies, the public,and funding agencies have accepted EBM with remarkable enthusiasm. The concept of evidence-based practice is now applied in management, education, criminology, and social work. Yet, EBM has attracted controversy: its critics allege that EBM uses a narrow concept of evidence and a naive conception of the relationships between evidence, theory, and practice. They also contend that EBM presents itself as a radical restructuring of medical knowledge that discredits more traditional ways of knowing in medicine, largely in the interests of people with a particular investment in the enterprise of large-scale clinical trials. Because EBM proposes aspecific relationship between theory, evidence, and knowledge, its theoretical basis can be understood as an epistemological system. Undertaking epistemological inquiry is important because the adoption of a particular epistemological view defines how science is conducted. In this paper, we challenge this critical view of EBM by examining how EBM fits into broad epistemological debates within the philosophy of science. We consider how EBM relates to some classical debates regarding the nature of science and knowledge. We investigate EBM from the perspective of major epistemological theories (logical-positivism/inductivism, deductivism/falsificationism/theory-ladeness of observations, explanationism/holism, instrumentalism, underdetermination theory by evidence). We first explore the relationship between evidence and knowledge and discuss philosophical support for the main way that evidence is used in medicine: (1) in the philosophical tradition that "rational thinkers respect their evidence," we show that EBM refers to making medical decisions that are consistent with evidence, (2) as a reliable sign, symptom, or mark to

    We aimed to review and discuss the evidence-based arguments for the efficacy of electroconvulsive therapy (ECT) in the treatment of catatonia. Randomized controlled trials (RCTs) and observational studies focusing on the response to ECT in catatonia were selected in PubMed, the Cochrane Library, Embase, ClinicalTrials.gov and Current Controlled Trials through October 2016 and qualitatively described. Trials assessing pre-post differences using a catatonia or clinical improvement rating scale were pooled together using a random effect model. Secondary outcomes were adverse effects of anesthesia and seizure. 564 patients from 28 studies were included. RCTs were of low quality and were heterogeneous; therefore, it was not possible to combine their efficacy results. An improvement of catatonic symptoms after ECT treatment was evidenced in ten studies (SMD = -3.14, 95% CI [-3.95; -2.34]). The adverse effects that were reported in seven studies included mental confusion, memory loss, headache, or adverse effects associated with anesthesia. ECT protocols were heterogeneous. The literature consistently describes improvement in catatonic symptoms after ECT. However, the published studies fail to demonstrate efficacy and effectiveness. It is now crucial to design and perform a quality RCT to robustly validate the use of ECT in catatonia.Prospero registration information: PROSPERO 2016: CRD42016041660.

    Full Text Available There is controversy in the literature regarding a number of topics related to anterior cruciate ligament (ACLreconstruction. The purpose of this article is to answer the following questions: 1 Bone patellar tendon bone (BPTB reconstruction or hamstring reconstruction (HR; 2 Double bundle or single bundle; 3 Allograft or authograft; 4 Early or late reconstruction; 5 Rate of return to sports after ACL reconstruction; 6 Rate of osteoarthritis after ACL reconstruction. A Cochrane Library and PubMed (MEDLINE search of systematic reviews and meta-analysis related to ACL reconstruction was performed. The key words were: ACL reconstruction, systematic reviews and meta-analysis. The main criteria for selection were that the articles were systematic reviews and meta-analysesfocused on the aforementioned questions. Sixty-nine articles were found, but only 26 were selected and reviewed because they had a high grade (I-II of evidence. BPTB-R was associated with better postoperative knee stability but with a higher rate of morbidity. However, the results of both procedures in terms of functional outcome in the long-term were similar. The double-bundle ACL reconstruction technique showed better outcomes in rotational laxity, although functional recovery was similar between single-bundle and double-bundle. Autograft yielded better results than allograft. There was no difference between early and delayed reconstruction. 82% of patients were able to return to some kind of sport participation. 28% of patients presented radiological signs of osteoarthritis with a follow-up of minimum 10 years.

  20. Evidence-based pathology: umbilical cord coiling.

    Khong, T Y

    2010-12-01

    The generation of a pathology test result must be based on criteria that are proven to be acceptably reproducible and clinically relevant to be evidence-based. This review de-constructs the umbilical cord coiling index to illustrate how it can stray from being evidence-based. Publications related to umbilical cord coiling were retrieved and analysed with regard to how the umbilical coiling index was calculated, abnormal coiling was defined and reference ranges were constructed. Errors and other influences that can occur with the measurement of the length of the umbilical cord or of the number of coils can compromise the generation of the coiling index. Definitions of abnormal coiling are not consistent in the literature. Reference ranges defining hypocoiling or hypercoiling have not taken those potential errors or the possible effect of gestational age into account. Even the way numerical test results in anatomical pathology are generated, as illustrated by the umbilical coiling index, warrants a critical analysis into its evidence base to ensure that they are reproducible or free from errors.

    Organizational and wider health system factors influence the implementation and success of interventions. Clinical Pathways in Acute Coronary Syndromes 2 is a cluster randomized trial of a clinical pathway-based intervention to improve acute coronary syndrome care in hospitals in China. We performed a qualitative evaluation to examine the system-level barriers to implementing clinical pathways in the dynamic healthcare environment of China. A qualitative descriptive analysis of 40 in-depth interviews with health professionals conducted in a sample of 10 hospitals purposively selected to explore barriers to implementation of the intervention. Qualitative data were analyzed using the Framework method. In-depth interviews identified 5 key system-level barriers to effective implementation: (1) leadership support for implementing quality improvement, (2) variation in the capacity of clinical services and quality improvement resources, (3) fears of patient disputes and litigation, (4) healthcare funding constraints and high out-of-pocket expenses, and (5) patient-related factors. System-level barriers affect the ability of acute coronary syndrome clinical pathways to change practice. Addressing these barriers in the context of current and planned national health system reform will be critical for future improvements in the management of acute coronary syndromes, and potentially other hospitalized conditions, in China.

From the literature search (n = 26), the most prevalent features were (1) PHR or Web server synchronization, 18 (69%), (2) insulin and medication recording, 17 (65%), (3) diet recording, 17 (65%), and (4) data export and communication, 16 (62%). Interestingly, although clinical guidelines widely refer to the importance of education, this is missing from the top functionalities in both cases. Conclusions While a wide selection of mobile applications seems to be available for people with diabetes, this study shows there are obvious gaps between the evidence-based recommendations and the functionality used in study interventions or found in online markets. Current results confirm personalized education as an underrepresented feature in diabetes mobile applications. We found no studies evaluating social media concepts in diabetes self-management on mobile devices, and its potential remains largely unexplored. PMID:21979293

    Full Text Available Legal actions have been playing a significant role as an alternative pathway to access to medicines in Brazil. These lawsuits demand medicines used in Primary Health Care as well as medicines that are still in clinical research and have not been market approved by the Brazilian National Agency for Sanitary Surveillance (ANVISA. The goal was to analyze medicines demanded through lawsuits brought to the judicial district which includes the city of Rio de Janeiro, Brazil, from July/2007 to June/2008. The medicines in 281 lawsuits were examined for their respective indications, classified according to their presence in publicly-funded lists, market approval by ANVISA, compliance with national clinical guidelines, existence of alternative therapies in lists and support of indication by scientific evidence. Six different categories were described, which are deemed useful to managers and the Judiciary in decision-making. The support of evidence is of utmost importance for medicines that are not included in public funding lists and also for those with no available therapeutic alternatives.

    Full Text Available Objective ‐ To examine the evidence based management literature, as an example of evidence based practice, and determine how applicable evidence based management might be in the special library environment. Methods ‐ Recent general management literature and the subject‐focused literature of evidence based management were reviewed; likewise recent library/information science management literature and the subject‐focused literature of evidence based librarianshipwere reviewed to identify relevant examples of the introduction and use of evidence based practice in organizations. Searches were conducted in major business/management databases, major library/information science databases, and relevant Web sites, blogs and wikis. Citation searches on key articles and follow‐up searches on cited references were also conducted. Analysis of the retrieved literature was conducted to find similarities and/or differences between the management literature and the library/information scienceliterature, especially as it related to special libraries.Results ‐ The barriers to introducing evidence based management into most organizations were found to apply to many special libraries and are similar to issues involved with evidence based practice in librarianship in general. Despite these barriers, a set of resources to assist special librarians in accessing research‐based information to help them use principles of evidence based management is identified.Conclusion ‐ While most special librarians are faced with a number of barriers to using evidence based management, resources do exist to help overcome these obstacles.

    It is important to analyze the influence mechanism of energy-related carbon emissions from a regional perspective to effectively achieve reductions in energy consumption and carbon emissions in China. Based on the "energy-economy-carbon emissions" hybrid input-output analysis framework, this study conducted structural decomposition analysis (SDA) on carbon emissions influencing factors in Guangdong Province. Systems-based examination of direct and indirect drivers for regional emission is presented. (1) Direct effects analysis of influencing factors indicated that the main driving factors of increasing carbon emissions were economic and population growth. Carbon emission intensity was the main contributing factor restraining carbon emissions growth. (2) Indirect effects analysis of influencing factors showed that international and interprovincial trades significantly affected the total carbon emissions. (3) Analysis of the effects of different final demands on the carbon emissions of industrial sector indicated that the increase in carbon emission arising from international and interprovincial trades is mainly concentrated in energy- and carbon-intensive industries. (4) Guangdong had to compromise a certain amount of carbon emissions during the development of its export-oriented economy because of industry transfer arising from the economic globalization, thereby pointing to the existence of the "carbon leakage" problem. At the same time, interprovincial export and import resulted in Guangdong transferring a part of its carbon emissions to other provinces, thereby leading to the occurrence of "carbon transfer."

However, definitions are in themselves insufficient to explain the underlying processes of EBP and to differentiate between an evidence-based process and evidence-based outcome. There is a need for a clear statement of what Evidence-Based Practice (EBP means, a description of the skills required to practise in an evidence-based manner and a curriculum that outlines the minimum requirements for training health professionals in EBP. This consensus statement is based on current literature and incorporating the experience of delegates attending the 2003 Conference of Evidence-Based Health Care Teachers and Developers ("Signposting the future of EBHC". Discussion Evidence-Based Practice has evolved in both scope and definition. Evidence-Based Practice (EBP requires that decisions about health care are based on the best available, current, valid and relevant evidence. These decisions should be made by those receiving care, informed by the tacit and explicit knowledge of those providing care, within the context of available resources. Health care professionals must be able to gain, assess, apply and integrate new knowledge and have the ability to adapt to changing circumstances throughout their professional life. Curricula to deliver these aptitudes need to be grounded in the five-step model of EBP, and informed by ongoing research.

Summary All health care professionals need to understand the principles of EBP, recognise EBP in action, implement evidence-based policies, and have a critical attitude to their own practice and to evidence. Without these skills, professionals and organisations will find it difficult to provide 'best practice'.

    There are still no clearly defined clinical-practice guidelines related to surgical intervention for chronic low back pain (CLBP) in the absence of serious structural problems such as instability, spinal stenosis, spondylolysis, infection, or neoplasm. There is also a lack of high-quality evidence regarding CLBP treatment. To compare the clinical effectiveness of lumbar surgery vs. nonsurgical treatment for chronic low back pain. A search was conducted using MEDLINE®, Embase, and reference lists of articles and personal files. After a systematic search, studies were selected on the basis of inclusion criteria. Six articles (904 patients) met the inclusion criteria for the study. Pooled estimates of clinical results were calculated with 95% confidence intervals. All six eligible studies were independent randomized clinical trials. Pooled data revealed that, compared with surgical treatment, nonsurgical treatment was associated with better Oswestry Disability Index scores. Both groups had similar Visual Analogue Scale and Emotional Distress Scale scores as well as General Function Scores. For chronic low back pain, nonsurgical treatment was shown to be effective, feasible, and safe during the follow-up period. More randomized controlled trials are needed to compare surgical and nonsurgical treatment of chronic low back pain.

    Decision analysis is a tool that clinicians can use to choose an option that maximizes the overall net benefit to a patient. It is an explicit, quantitative, and systematic approach to decision making under conditions of uncertainty. In this article, we present two teaching tips aimed at helping clinical learners understand the use and relevance of decision analysis. The first tip demonstrates the structure of a decision tree. With this tree, a clinician may identify the optimal choice among complicated options by calculating probabilities of events and incorporating patient valuations of possible outcomes. The second tip demonstrates how to address uncertainty regarding the estimates used in a decision tree. We field tested the tips twice with interns and senior residents. Teacher preparatory time was approximately 90 minutes. The field test utilized a board and a calculator. Two handouts were prepared. Learners identified the importance of incorporating values into the decision-making process as well as the role of uncertainty. The educational objectives appeared to be reached. These teaching tips introduce clinical learners to decision analysis in a fashion aimed to illustrate principles of clinical reasoning and how patient values can be actively incorporated into complex decision making.

    Patients often seek guidance from the aesthetic practitioners regarding treatments to enhance their 'beauty'. Is there a science behind the art of assessment and if so is it measurable? Through the centuries, this question has challenged scholars, artists and surgeons. This study aims to undertake a review of the evidence behind quantitative facial measurements in assessing beauty to help the practitioner in everyday aesthetic practice. A Medline, Embase search for beauty, facial features and quantitative analysis was undertaken. Inclusion criteria were studies on adults, and exclusions included studies undertaken for dental, cleft lip, oncology, burns or reconstructive surgeries. The abstracts and papers were appraised, and further studies excluded that were considered inappropriate. The data were extracted using a standardised table. The final dataset was appraised in accordance with the PRISMA checklist and Holland and Rees' critique tools. Of the 1253 studies screened, 1139 were excluded from abstracts and a further 70 excluded from full text articles. The remaining 44 were assessed qualitatively and quantitatively. It became evident that the datasets were not comparable. Nevertheless, common themes were obvious, and these were summarised. Despite measures of the beauty of individual components to the sum of all the parts, such as symmetry and the golden ratio, we are yet far from establishing what truly constitutes quantitative beauty. Perhaps beauty is truly in the 'eyes of the beholder' (and perhaps in the eyes of the subject too). This journal requires that authors assign a level of evidence to each article.

    The main purposes of this study were to elucidate the effects of supervised-exercise training (ET) interventions on hepatic fat content and on non-alcoholic fatty liver disease (NAFLD) prevalence in children and adolescents and to provide information about the optimal ET prescription (type, intensity, volume, and frequency) needed to reduce hepatic fat content in youths. Supervised-ET interventions performed in children and adolescents (6-19 years) that provided results of exercise effects on hepatic fat content or NAFLD prevalence were included. Supervised-exercise significantly reduced hepatic fat content compared to the control groups. Lifestyle interventions that included supervised-ET significantly reduced the prevalence of NAFLD. This systematic review and meta-analysis shows that supervised-ET could be an effective strategy in the management and prevention of NAFLD in children and adolescents. Both aerobic and resistance ET, at vigorous or moderate-to-vigorous intensities, with a volume ≥60 min/session and a frequency ≥3 sessions/week, aiming to improve cardiorespiratory fitness and muscular strength, had benefits on hepatic fat content reduction in youth. These data concur with the international recommendations of physical activity for health promotion in youth and may be useful when designing ET programs to improve and prevent hepatic steatosis in the pediatric population.

    The phenomenon of the physical, moral or psychical violence in the working environment, variously indicated as "mobbing", "workplace bullying" or "workplace harassment", is to date object of numerous studies, mostly of epidemiological type, which are yet to clear, in a sufficient way, the aspects of that phenomenon, the possible causes, risk factors, constituent characteristics and consequences. Our search, a systematic review of the existing studies in literature and a meta-analysis of the jobs chosen to such scope, has shown that only a small percentage of the researches conducted on the topic is represented from studies that collected original information on the subject. The results of the meta-analysis show that in the category of the mobbed workers the psychosomatic disturbs, stress, and anxiety are greater than in the group of controls and that the perception of the surrounding environment is more negative in the victims of mobbing compared with the not mobbed workers. The value of such results is reduced by the characteristics and the heterogeneity of the studies.

    New anti-angiogenesis pharmacotherapies have dramatically altered treatment of age-related macular degeneration (AMD), the leading cause of blindness in older adults. Monthly intraocular injections however, are extremely burdensome to ophthalmologists, patients, and their families. Repeated injections also increase risks of complications or adverse events. Although the pharmacokinetics of anti-vascular endothelial growth factor (A-VEGF) drugs are fairly well known, an individuals' AMD presentation and their pharmacodynamics or response to the drug has been shown to be extremely variable.

  2. Evidence-based management: a literature review.

    Science.gov (United States)

    Young, Sam K

    2002-05-01

    This paper presents a review of evidence-based management (EBM), exploring whether management activities within healthcare have been, or can be, subject to the same scientific framework as clinical practice. The evidence-based approach was initially examined, noting the hierarchy of evidence ranging from randomized control trials to clinical anecdote. The literature varied in its degree of criticism of this approach; the most common concern referring to the assumed superiority of positivism. However, evidence-based practice was generally accepted as the best way forward. Stewart (1998) offered the only detailed exposition of EBM, outlining a necessary 'attitude of mind' both for EBM and for the creation of a research culture. However, the term 'clinical effectiveness' emerged as a possible replacement buzz-word for EBM (McClarey 1998). The term appears to encompass the sentiments of the evidence-based approach, but with a concomitant concern for economic factors. In this paper the author has examined the divide between those who viewed EBM as an activity for managers to make their own practice accountable and those who believed it to be a facilitative practice to help clinicians with evidence-based practice. Most papers acknowledged the limited research base for management activities within the health service and offered some explanation such as government policy constraints and lack of time. Nevertheless, the overall emphasis is that ideally there should be a management culture firmly based in evidence.

    Intervention is a key concept in the technology of psychology and it plays a decisive role in evidence-based research. But analyses of this concept are remarkably sparse. Based on a critical analysis of the conception of intervention in the American Psychological Association’s guidelines...... for evidence-based research and practice, I argue that, while psychological interventions are primarily meant to work in people’s everyday lives, how interventions do so is barely addressed and poorly captured.

    A Probabilistic Analysis of the Sacco and Vanzetti Evidence is a Bayesian analysis of the trial and post-trial evidence in the Sacco and Vanzetti case, based on subjectively determined probabilities and assumed relationships among evidential events. It applies the ideas of charting evidence and probabilistic assessment to this case, which is perhaps the ranking cause celebre in all of American legal history. Modern computation methods applied to inference networks are used to show how the inferential force of evidence in a complicated case can be graded. The authors employ probabilistic assess

    To demonstrate how the core characteristics of both evidence-based medicine (EBM) and evidence-based health care (EBHC) can be adapted to health sciences librarianship. Narrative review essay involving development of a conceptual framework. The author describes the central features of EBM and EBHC. Following each description of a central feature, the author then suggests ways that this feature applies to health sciences librarianship. First, the decision-making processes of EBM and EBHC are compatible with health sciences librarianship. Second, the EBM and EBHC values of favoring rigorously produced scientific evidence in decision making are congruent with the core values of librarianship. Third, the hierarchical levels of evidence can be applied to librarianship with some modifications. Library researchers currently favor descriptive-survey and case-study methods over systematic reviews, randomized controlled trials, or other higher levels of evidence. The library literature nevertheless contains diverse examples of randomized controlled trials, controlled-comparison studies, and cohort studies conducted by health sciences librarians. Health sciences librarians are confronted with making many practical decisions. Evidence-based librarianship offers a decision-making framework, which integrates the best available research evidence. By employing this framework and the higher levels of research evidence it promotes, health sciences librarians can lay the foundation for more collaborative and scientific endeavors.

    e-Health is experiencing a difficult time. On the one side, the forecast is for a bright digital health future created by precision medicine and smart devices. On the other hand, most large scale e-health projects struggle to make a difference and are often controversial. Both futures fail because they are not evidence-based. Medical informatics should follow the example of evidence-based medicine, i.e. conduct rigorous research that gives us evidence to solve real world problems, synthesise that evidence and then apply it strictly. We already have the tools for creating a different universe. What we need is evidence, will, a culture of learning, and hard work.

    Blended learning describes a combination of teaching methods, often utilizing digital technologies. Research suggests that learner outcomes can be improved through some blended learning formats. However, the cost-effectiveness of delivering blended learning is unclear. This study aimed to determine the cost-effectiveness of a face-to-face learning and blended learning approach for evidence-based medicine training within a medical program. The economic evaluation was conducted as part of a randomized controlled trial (RCT) comparing the evidence-based medicine (EBM) competency of medical students who participated in two different modes of education delivery. In the traditional face-to-face method, students received ten 2-hour classes. In the blended learning approach, students received the same total face-to-face hours but with different activities and additional online and mobile learning. Online activities utilized YouTube and a library guide indexing electronic databases, guides, and books. Mobile learning involved self-directed interactions with patients in their regular clinical placements. The attribution and differentiation of costs between the interventions within the RCT was measured in conjunction with measured outcomes of effectiveness. An incremental cost-effectiveness ratio was calculated comparing the ongoing operation costs of each method with the level of EBM proficiency achieved. Present value analysis was used to calculate the break-even point considering the transition cost and the difference in ongoing operation cost. The incremental cost-effectiveness ratio indicated that it costs 24% less to educate a student to the same level of EBM competency via the blended learning approach used in the study, when excluding transition costs. The sunk cost of approximately AUD $40,000 to transition to the blended model exceeds any savings from using the approach within the first year of its implementation; however, a break-even point is achieved within its

    Current health care reform in the United States is producing a shift in radiology practice from the traditional volume-based role of performing and interpreting a large number of examinations to providing a more affordable and higher-quality service centered on patient outcomes, which is described as a value-based approach to the provision of health care services. In the 1990 s, evidence-based medicine was defined as the integration of current best evidence with clinical expertise and patient values. When these methods are applied outside internal medicine, the process is called evidence-based practice (EBP). EBP facilitates understanding, interpretation, and application of the best current evidence into radiology practice, which optimizes patient care. It has been incorporated into "Practice-based Learning and Improvement" and "Systems-based Practice," which are two of the six core resident competencies of the Accreditation Council for Graduate Medical Education and two of the 12 American Board of Radiology milestones for diagnostic radiology. Noninterpretive skills, such as systems-based practice, are also formally assessed in the "Quality and Safety" section of the American Board of Radiology Core and Certifying examinations. This article describes (a) the EBP framework, with particular focus on its relevance to the American Board of Radiology certification and maintenance of certification curricula; (b) how EBP can be integrated into a residency program; and (c) the current value and likely place of EBP in the radiology information technology infrastructure.

    randomization, type of control intervention, outcome measures for effectiveness and safety, and length of follow-up. The quality of the studies and level of the evidence was initially scored by one clinical epidemiologist using the Jadad scale and GRADE approach. Level of quality depends on the amount of certainty about the magnitude of effect and is based on study designs, extent of methodological limitations, consistency of results and applicability (i.e. directness) to the Ontario clinical context. The GRADE approach also permits comment on the strength of recommendations resulting from the evidence, based on estimates of the magnitude of effect relative to the magnitude of risk and burden and the level of certainty around these estimates. The quality assessments were subsequently peer-reviewed. The literature search revealed 2 previous health technology assessments, 3 meta-analyses of placebo-controlled trials, 1 Cochrane review and meta-analysis encompassing 18 randomized controlled trials (RCTs) that compared hylan G-F 20 to either placebo or active treatments, 11 RCTs of hylan G-F 20 (all included in the Cochrane review), and 10 observational studies. Given the preponderance of evidence, the Medical Advisory Secretariat's analysis focused on studies with Level 1 evidence of effectiveness (i.e., the meta-analyses of RCTs and the RCTs). Only safety data from the observational studies were included. The authors of the 2 health technology assessments concluded that the data were sparse and poor quality. There was some evidence that hylan G-F 20 delivered a small, clinical benefit at 3 to 6 months after treatment on a magnitude comparable to NSAIDs and intra-articular steroids. Hylan G-F 20 appeared to carry a risk of a local adverse reaction of in the range of 3% to 18% per 100 injections, but there was no apparent risk of a severe adverse event, although the data were limited. Each of the 3 meta-analyses of placebo-controlled trials of intra-articular hyaluronans had only 3

    When assessing the quality of clinical trials in intermittent claudication, on principle the same strict biometric and medical standards need to be applied for studies on the effect of walking exercise as for conservative drug treatment studies. However, as demonstrated by a recent review of the Cochrane Collaboration, this is apparently not always the case. The review included ten randomized controlled studies published between 1966 and 1997 with a total of 258 patients. The exercise regimes varied considerably between studies with regard to mode, intensity, frequency, duration and supervision, just as the treadmill tests employed to measure walking distance and walking time, respectively (primary endpoint). None of these studies used a confirmatory approach, and they all have a number of further methodological flaws when taking current biometric and medical guidelines into account. Also unmentioned in the abstract remains the important fact that, owing to missing data, finally only 53 patients from three studies could be pooled for the actual meta-analysis. All in all, the Cochrane review under discussion here is hardly suitable to scientifically prove the generally accepted efficacy of walking exercise in intermittent claudication. At the same time, it becomes clear that even publications of well-reputed institutions such as the Cochrane Collaboration should always be critically scrutinized. On the other hand, applying modern guidance for investigation under the aspect of evidence based medicine must not lead to a retrospective discrimination of accepted historical scientific data and thereby call into question proven therapeutic strategies.

    2013-09-01

    Our "desired outcome" in writing this article was to present not only key process issues stemming from the Cognitive Behavioral Analysis System of Psychotherapy (CBASP; McCullough, 2000), but to highlight those therapy maneuvers that we, a "seasoned" clinician/supervisor and a clinical trainee, find most useful in delivering treatment and in conducting supervision. We strongly believe that it is only through the translation of evidence-based therapeutic models, such as CBASP, into effective training that a true integration of science and practice can be obtained. Thus, the congruence of trainer's and trainee's views on what constitute top process issues in therapy is important in evaluating the reliability of a therapy model; with this in mind, we focus on three process issues, as follows: (1) problems are anchored to the "here and now" and to specific situational outcomes; (2) patients are encouraged to identify the role they play in affecting their distressing outcomes and to take responsibility for "fixing" them; and (3) the therapist planfully engages in the process of change via disciplined personal involvement. Research and theory supporting these maneuvers are presented, in conjunction with clinical examples. 2013 APA, all rights reserved

    Full Text Available Traditionally, clinical decisions in dentistry have been based on the experience of the dentist. If the given treatment works, it was utilized again, but if the results were disappointing, the procedure was deserted. Evaluating clinical treatment in this fashion is difficult because it is hard to know which factors are important for success and which contribute to failure. This came with the concept of evidence-based approach which facilitates conclusions for clinical practice based on sound research studies.

    To provide an overview of evidence-based medicine (EBM) in relation to radiology and to define a policy for adoption of this principle in the European radiological community. Starting from Sackett's definition of EBM we illustrate the top-down and bottom-up approaches to EBM as well as EBM's limitations. Delayed diffusion and peculiar features of evidence-based radiology (EBR) are defined with emphasis on the need to shift from the demonstration of the increasing ability to see more and better, to the demonstration of a significant change in treatment planning or, at best, of a significant gain in patient outcome. The ''as low as reasonably achievable'' (ALARA) principle is thought as a dimension of EBR while EBR is proposed as part of the core curriculum of radiology residency. Moreover, we describe the process of health technology assessment in radiology with reference to the six-level scale of hierarchy of studies on diagnostic tests, the main sources of bias in studies on diagnostic performance, and levels of evidence and degrees of recommendations according to the Centre for Evidence-Based Medicine (Oxford, UK) as well as the approach proposed by the GRADE working group. Problems and opportunities offered by evidence-based guidelines in radiology are considered. Finally, we suggest nine points to be actioned by the ESR in order to promote EBR. Radiology will benefit greatly from the improvement in practice that will result from adopting this more rigorous approach to all aspects of our work. (orig.)

    This meta-analysis examined the enduring efficacy of evidence-based psychotherapies (EBP) in comparison to treatment as usual (TAU) by examining effects from termination to follow-up for acute anxiety and depression in an adult outpatient population. It was hypothesized that EBPs might extend their efficacy at follow-up assessment (Tolin, 2010). Longitudinal multilevel meta-analyses were conducted that examined the magnitude of difference between EBP and TAU. Targeted (disorder-specific) outcomes were examined, along with dropout rates at follow-up assessments. A total of 15 comparisons (including 30 repeated effect sizes [ES]) were included in this meta-analysis (average of 8.9 month follow-up). Small to moderate ES differences were found to be in favor of EBPs at 0-4 month assessments (Hedges' g=0.40) and up to 12-18 month assessments (g=0.20), indicating no extended efficacy at follow-up. However, the TAU-conditions were heterogeneous, ranging from absence of minimal mental health treatment to legitimate psychotherapeutic interventions provided by trained professionals, the latter of which resulted in smaller ES differences. Furthermore, samples where substance use comorbidities were not actively excluded indicated smaller ES differences. TAU-conditions produced slightly higher dropout rates than EBP-conditions. Findings indicate small and no extended superiority of EBP for acute depression and anxiety disorders in comparison to TAU at follow-up assessment. There are a limited number of studies investigating the transportability and lasting efficacy of EBP compared to TAU, especially to TAU with equivalent conditions between treatment groups.

    Understanding principles of evidence-based medicine is of vital importance for improving quality of care, promoting public health and health system development. Understanding principles of evidence-based medicine allows using the most powerful information source, which have ever existed in medicine. To evaluate the effectiveness of teaching Evidence-Based Medicine, including long-term outcomes of training. The study was conducted at the Medical University of Astana, where the Scientific and Educational Center of Evidence-Based Medicine was established in 2010 with the help of the corresponding project of the World Bank. The participants of the study were the faculty trained in Evidence-Based Medicine at the workshop "Introduction to Evidence-Based Medicine" for the period of 2010-2015 years. There were a total of 16 workshops during the period, and 323 employees were trained. All participants were asked to complete our questionnaire two times: before the training - pre-training (to determine the initial level of a listener) and after the training - post-training (to determine the acquired level and get the feedback). Questionnaires were prepared in such a way, that the majority of questions before and after training were identical. Thus, it provided a clear picture of the effectiveness of training. Questions in the survey were open-ended so that the respondents had the opportunity to freely and fully express their views. The main part of the questionnaires included the following questions: "Do you understand what evidence-based medicine is", "how do you understand what the study design means", "what is randomization", "how research is classified", "do you know the steps of decision-making according to Evidence-Based Medicine, list them", "what literature do you prefer to use when searching for information (print, electronic, etc.)", "what resources on the Internet do you prefer to use".

    Educational reforms in resident training have historically been driven by reports from medical societies and organizations. Although educational initiatives are well intended, they are rarely supported by robust evidence. The Accreditation Council for Graduate Medical Education recently introduced competency-based training, a form of outcomes-based education that has been used successfully in nonmedical professional vocations. This initiative has promise to advance the quality of resident education, but questions remain regarding implementation within plastic surgery. In particular, how will competency-based training impact patient outcomes, and will the methodologies used to assess competencies (i.e., milestones) be accurate and validated by literature? This report investigates resident educational reform and the need for more evidence-based educational initiatives in plastic surgery training.

    Full Text Available Evidence-based practice (EBP implementation requires substantial resources in workforce training; yet, failure to achieve long-term sustainment can result in poor return on investment. There is limited research on EBP sustainment in mental health services long after implementation. This study examined therapists’ continued vs. discontinued practice delivery based on administrative claims for reimbursement for six EBPs [Cognitive Behavioral Interventions for Trauma in Schools (CBITS, Child–Parent Psychotherapy, Managing and Adapting Practices (MAP, Seeking Safety (SS, Trauma-Focused Cognitive Behavior Therapy (TF-CBT, and Positive Parenting Program] adopted in a system-driven implementation effort in public mental health services for children. Our goal was to identify agency and therapist factors associated with a sustained EBP delivery. Survival analysis (i.e., Kaplan–Meier survival functions, log-rank tests, and Cox regressions was used to analyze 19 fiscal quarters (i.e., approximately 57 months of claims data from the Prevention and Early Intervention Transformation within the Los Angeles County Department of Mental Health. These data comprised 2,322,389 claims made by 6,873 therapists across 88 agencies. Survival time was represented by the time elapsed from therapists’ first to final claims for each practice and for any of the six EBPs. Results indicate that therapists continued to deliver at least one EBP for a mean survival time of 21.73 months (median = 18.70. When compared to a survival curve of the five other EBPs, CBITS, SS, and TP demonstrated a higher risk of delivery discontinuation, whereas MAP and TF-CBT demonstrated a lower risk of delivery discontinuation. A multivariate Cox regression model revealed that agency (centralization and service setting and therapist (demographics, discipline, and case-mix characteristics characteristics were significantly associated with risk of delivery discontinuation for any of

    2011-01-01

    Background Acutely swollen or painful joints are common complaints in the emergency department (ED). Septic arthritis in adults is a challenging diagnosis, but prompt differentiation of a bacterial etiology is crucial to minimize morbidity and mortality. Objectives The objective was to perform a systematic review describing the diagnostic characteristics of history, physical examination, and bedside laboratory tests for nongonococcal septic arthritis. A secondary objective was to quantify test and treatment thresholds using derived estimates of sensitivity and specificity, as well as best-evidence diagnostic and treatment risks and anticipated benefits from appropriate therapy. Methods Two electronic search engines (PUBMED and EMBASE) were used in conjunction with a selected bibliography and scientific abstract hand search. Inclusion criteria included adult trials of patients presenting with monoarticular complaints if they reported sufficient detail to reconstruct partial or complete 2 × 2 contingency tables for experimental diagnostic test characteristics using an acceptable criterion standard. Evidence was rated by two investigators using the Quality Assessment Tool for Diagnostic Accuracy Studies (QUADAS). When more than one similarly designed trial existed for a diagnostic test, meta-analysis was conducted using a random effects model. Interval likelihood ratios (LRs) were computed when possible. To illustrate one method to quantify theoretical points in the probability of disease whereby clinicians might cease testing altogether and either withhold treatment (test threshold) or initiate definitive therapy in lieu of further diagnostics (treatment threshold), an interactive spreadsheet was designed and sample calculations were provided based on research estimates of diagnostic accuracy, diagnostic risk, and therapeutic risk/benefits. Results The prevalence of nongonococcal septic arthritis in ED patients with a single acutely painful joint is approximately 27

    This study aimed at estimating the efficiency of palivizumab in the prevention of Respiratory Syncytial Virus (RSV) infection and its sequelae in preterm infants (32 day 1 -35 day 0 weeks of gestational age -wGA-) in Spain. A decision-tree model was developed to compare health benefits (Quality Adjusted Life Years-QALYs) and costs of palivizumab versus a non-prophylaxis strategy over 6 years. A hypothetical cohort of 1,000 preterm infants, 32 day 1 -35 day 0 wGA (4.356 kg average weight) at the beginning of the prophylaxis (15 mg/kg of palivizumab; 3.88 average number of injections per RSV season) was analysed. The model considered the most recent evidence from Spanish observational and epidemiological studies on RSV infection: the FLIP II study provided hospital admission and Intensive Care Unit (ICU) admission rates; in-hospital mortality rate was drawn from an epidemiological study from 2004 to 2012; recurrent wheezing rates associated to RSV infection from SPRING study were adjusted by the evidence on the palivizumab effect from clinical trials. Quality of life baseline value, number of hospitalized infants and the presence of recurrent wheezing over time were granted to estimate QALYs. National Health Service and societal perspective (included also recurrent wheezing indirect cost) were analysed. Total costs (€, 2016) included pharmaceutical and administration costs, hospitalization costs and recurrent wheezing management annual costs. A discount rate of 3.0% was applied annually for both costs and health outcomes. Over 6 years, the base case analysis showed that palivizumab was associated to an increase of 0.0731 QALYs compared to non-prophylaxis. Total costs were estimated in €2,110.71 (palivizumab) and €671.68 (non-prophylaxis) from the National Health System (NHS) perspective, resulting in an incremental cost utility ratio (ICUR) of €19,697.69/QALYs gained (prophylaxis vs non-prophylaxis).

    The extensile lateral approach (ELA) has been widely performed for displaced intra-articular calcaneal fractures (DIACFs), and wound complications remain a significant problem. As a minimal incision technique, the sinus tarsi approach (STA) was designed to overcome this disadvantage. There were already many reports about this approach but the conclusions were not completely consistent. Based on the current evidence, we performed this meta-analysis to compare the STA with ELA in the management of DIACF and expected to draw a certain and meaningful conclusion. All potentially relevant randomized controlled trials (RCTs) and cohort studies (CSs) were searched in the databases of PubMed, Embase, Cochrane Central Register of Controlled Trials (CENTRAL) and ClinicalTrial.gov. The desirable outcomes including wound complications, excellent and good rate, secondary surgery rate and Böhler's angle were extracted. RCT studies were assessed using the Risk of Bias Tool recommended by the Cochrane Collaboration, and cohort studies were evaluated using the Newcastle-Ottawa Scale. The data of RCTs and cohorts were pooled respectively using the fixed-effect model or random-effect model. Mean differences with 95% confidence intervals (CIs) were calculated for continuous data, and relative risks (RRs) with 95% CIs were calculated for dichotomous data. Statistical heterogeneity was assessed with the Q test and I 2 . Sensitivity analysis was developed to assess the reliability of pooled results. Seven studies including two RCTs and five CSs were eligible for the meta-analysis. No matter RCTs or CSs, the pooled data all showed that STA group had a lower incidence of wound complications than that in the ELA group and no significant difference was found in excellent and good rate and the recovery of Böhler's angle between the two groups. The CSs also showed that the STA group had a lower incidence of secondary surgeries than that in the ELA group. Through a STA, we not only can reduce

    Full Text Available Evidence based library and information practice (EBLIP is a strategy to bridge research and practice. Generally EBLIP is seen as a movement to encourage and give practitioners the means to incorporate research into their practice, where it previously may have been lacking. The widely accepted definition of EBLIP (Booth, 2000 stresses three aspects that contribute to a practice that is evidence based: 1 "the best available evidence;" 2 "moderated by user needs and preferences;" 3 "applied to improve the quality of professional judgements." The area that the EBLIP movement has focused on is how to create and understand the best available research evidence. CE courses, critical appraisal checklists, and many articles have been written to address a need for librarian education in this area, and it seems that strides have been made.But very little in the EBLIP literature talks about how we make professional judgements, or moderate evidence based on our user needs and preferences. Likewise, how do we make good evidence based decisions when our evidence base is weak. These things seem to be elements we just take for granted or can’t translate into words. It is in keeping with tacit knowledge that librarians just seem to have or acquire skills with education and on the job experience. Tacit knowledge is "knowledge that is not easily articulated, and frequently involves knowledge of how to do things. We can infer its existence only by observing behaviour and determining that this sort of knowledge is a precondition for effective performance" (Patel, Arocha, & Kaufman, 1999, p.78. It is something that is difficult to translate into an article or guideline for how we work. I think of this area as the "art" of evidence based practice. And the art is crucial to being an evidence based practitioner.Science = systematized knowledge, explicit research, methodological examination, investigation, dataArt = professional knowledge of your craft, intuition

  3. Applying Multi-Criteria Decision Analysis (MCDA) Simple Scoring as an Evidence-based HTA Methodology for Evaluating Off-Patent Pharmaceuticals (OPPs) in Emerging Markets.

    Off-patent pharmaceuticals (OPPs) represent more than 60% of the pharmaceutical market in many emerging countries, where they are frequently evaluated primarily on cost rather than with health technology assessment. OPPs are assumed to be identical to the originators. Branded and unbranded generic versions can, however, vary from the originator in active pharmaceutical ingredients, dosage, consistency formulation, excipients, manufacturing processes, and distribution, for example. These variables can alter the efficacy and safety of the product, negatively impacting both the anticipated cost savings and the population's health. In addition, many health care systems lack the resources or expertise to evaluate such products, and current assessment methods can be complex and difficult to adapt to a health system's needs. Multicriteria decision analysis (MCDA) simple scoring is an evidence-based health technology assessment methodology for evaluating OPPs, especially in emerging countries in which resources are limited but decision makers still must balance affordability with factors such as drug safety, level interchangeability, manufacturing site and active pharmaceutical ingredient quality, supply track record, and real-life outcomes. MCDA simple scoring can be applied to pharmaceutical pricing, reimbursement, formulary listing, and drug procurement. In November 2015, a workshop was held at the International Society for Pharmacoeconomics and Outcomes Research Annual Meeting in Milan to refine and prioritize criteria that can be used in MCDA simple scoring for OPPs, resulting in an example MCDA process and 22 prioritized criteria that health care systems in emerging countries can easily adapt to their own decision-making processes.

    Full Text Available Nel corso dell’ultimo decennio, nel pensiero pedagogico anglosassone, si è affermata una cultura dell’evidenza cui ci si riferisce con l’espressione “evidence based education” (EBE. Secondo tale prospettiva, le decisioni in ambito educativo dovrebbero essere assunte sulla base delle conoscenze che la ricerca empirica offre in merito alla minore o maggiore efficacia delle differenti opzioni didattiche. Si tratta di un approccio (denominato “evidence based practice” che ha origine in ambito medico e che in seguito ha trovato applicazione in differenti domini delle scienze sociali. L’autore presenta un quadro introduttivo all’EBE, dando conto delle sue origini e dei differenti significati di cui è portatrice.

    2010-05-01

    Full Text Available The process of facilitating the uptake of evidence, for example, scientific research findings, into the policymaking process is multifaceted and thus complex. It is therefore important for scientists to understand this process in order to influence it more effectively. Similarly, policymakers need to understand the complexities of the scientific process to improve their interaction with the scientific sphere. This literature review addresses those factors that influence the uptake of scientific evidence into policymaking, the barriers to using science in policymaking, as well as recommendations for improved science–policymaking interaction. A visual diagram of the gears of a car is used to convey the message of the complexities around the engagement between science and policymaking. It is concluded that the issue of evidence-based policymaking remains unresolved and questions for future research on the science–policy interface are raised.

  8. Can Scholarly Communication be Evidence Based? (Editorial

    2010-12-01

    Full Text Available This issue of Evidence Based Library and Information Practice includes three papers from the Evidence Based Scholarly Communication Conference (EBSCC that took place in March 2010i. Kroth, Philips and Eldredge have written a commentary that gives an overview of the conference, and introduces us to the research papers that were presented. As well, two research presentations from the conference appear in this issue, an article by Donahue about a potential new method of communicating between scholars, and a paper by Gilliland in our Using Evidence in Practice section, detailing a library’s Open Access Day preparations.Kroth, Philips and Eldredge note that “The EBSCC brought together librarians and information specialists to share evidence-based strategies for developing effective local scholarly communication support and training and, hopefully, form new coalitions to address this topic at a local and national level.” (p 108. This conference focused on translational medicine, and looked at how to promote new methods of scholarly communication, partially through the inclusion of research papers at the conference.The inclusion of these articles and the evidence based focus of the EBSCC conference, made me ask myself, can scholarly communication be evidence based? At its core, scholarly communication is anything but a scientific issue. It is charged with emotion; from authors, publishers, librarians and others involved in the business of publishing. The recent shift to look at new models of scholarly communication has been a threat to many of the established models and sparked much debate in the academic world, especially in relation to open access. In her 2006 EBLIP commentary on evidence based practice and open access, Morrison notes, “Open Access and evidence based librarianship are a natural combination” (p. 49, and outlines her perspective on many of the reasons why. Debate continues to rage, however, regarding how authors should

    Limited data is available on the role, and extent of, postchemotherapy lymphadenectomy (PC-LND) in patients with clinical evidence of pelvic (cN1-3) or retroperitoneal (RP) lymph node spread from urothelial bladder carcinoma. To compare the outcomes of operated versus nonoperated patients after first-line chemotherapy. Data from 34 centers was collected, totaling 522 patients, treated between January 2000 and June 2015. Criteria for patient selection were the following: bladder primary tumor, lymph node metastases (pelvic±RP) only, first-line platinum-based chemotherapy given. LND (with cystectomy) versus observation after first-line chemotherapy for metastatic urothelial bladder carcinoma. Overall survival (OS) was the primary endpoint. Multiple propensity score techniques were adopted, including 1:1 propensity score matching and inverse probability of treatment weighting. Additionally, the inverse probability of treatment weighting analysis was performed with the inclusion of the covariates, that is, with doubly robust estimation. Overall, 242 (46.4%) patients received PC-LND and 280 (53.6%) observation after chemotherapy. There were 177 (33.9%) and 345 (66.1%) patients with either RP or pelvic LND only, respectively. Doubly robust estimation-adjusted comparison was not significant for improved OS for PC-LND (hazard ratio [HR]: 0.86, 95% confidence interval [CI]: 0.56-1.31, p=0.479), confirmed by matched analysis (HR: 0.91, 95% CI: 0.60-1.36, p=0.628). This was also observed in the RP subgroup (HR: 1.12, 95% CI: 0.68-1.84). The retrospective nature of the data and the heterogeneous patient population were the major limitations. Although there were substantial differences between the two groups, after accounting for major confounders we report a nonsignificant OS difference with PC-LND compared with observation only. These findings may be hypothesis-generating for future prospective trials. We found no differences in survival by adding postchemotherapy

    Full Text Available Hypertension is an important worldwide public -health challenge with high mortality and disability. Due to the limitations and concerns with current available hypertension treatments, many hypertensive patients, especially in Asia, have turned to Chinese medicine (CM. Although hypertension is not a CM term, physicians who practice CM in China attempt to treat the disease using CM principles. A variety of approaches for treating hypertension have been taken in CM. For seeking the best evidence of CM in making decisions for hypertensive patients, a number of clinical studies have been conducted in China, which has paved the evidence-based way. After literature searching and analyzing, it appeared that CM was effective for hypertension in clinical use, such as Chinese herbal medicine, acupuncture, moxibustion, cupping, qigong, and Tai Chi. However, due to the poor quality of primary studies, clinical evidence is still weak. The potential benefits and safety of CM for hypertension still need to be confirmed in the future with well-designed RCTs of more persuasive primary endpoints and high-quality SRs. Evidence-based Chinese medicine for hypertension still has a long way to go.

  11. Evidence-based recommendation on toothpaste use

    2014-01-01

    Full Text Available Toothpaste can be used as a vehicle for substances to improve the oral health of individuals and populations. Therefore, it should be recommended based on the best scientific evidence available, and not on the opinion of authorities or specialists. Fluoride is the most important therapeutic substance used in toothpastes, adding to the effect of mechanical toothbrushing on dental caries control. The use of fluoride toothpaste to reduce caries in children and adults is strongly based on evidence, and is dependent on the concentration (minimum of 1000 ppm F and frequency of fluoride toothpaste use (2'/day or higher. The risk of dental fluorosis due to toothpaste ingestion by children has been overestimated, since there is no evidence that: 1 fluoride toothpaste use should be postponed until the age of 3-4 or older, 2 low-fluoride toothpaste avoids fluorosis and 3 fluorosis has a detrimental effect on the quality of life of individuals exposed to fluoridated water and toothpaste. Among other therapeutic substances used in toothpastes, there is evidence that triclosan/copolymer reduce dental biofilm, gingivitis, periodontitis, calculus and halitosis, and that toothpastes containing stannous fluoride reduce biofilm and gingivitis.

  12. Radiographers' preconditions for evidence-based radiography

    2010-01-01

    Evidence-based practice (EBP) is essential in today's health care, but its establishment requires several preconditions from individuals and organizations (e.g. knowledge, understanding, attitudes, abilities, self-confidence, support, and resources). Previous studies suggest that radiographers do generate and use evidence in their work, but evidence-based radiography (EBR) is not yet used routinely as established practice, especially in terms of research utilization. This paper aims to describe radiographers' preconditions for EBR, and their participation in research activities. Main focus is on research utilization. Using an electronic questionnaire developed for this study, a survey was conducted: data collected from Finnish radiographers and radiotherapists (N = 438) were analysed both statistically and qualitatively. The final response rate was 39%. The results suggest radiographers' preconditions for EBR to consist of knowledge of research, significance of research activities, research-orientated way of working, and support. In addition, adequate resourcing is essential. Reading scientific journals, participation in research activities, a higher degree of education, and senior post seem to be significant promoters of EBR and research utilization. The results support the notion that EBR, and especially research utilization, are not yet well-established in Finland, and radiographers' viewpoints concerning the role and significance of research evidence and research activities still seem to vary.

    2014-03-01

    The standard adjuvant treatment for glioblastoma is temozolomide concomitant with radiotherapy, followed by a further six cycles of temozolomide. However, due to the lack of empirical evidence and international consensus regarding the optimal duration of temozolomide treatment, it is often extended to 12 or more cycles, even in the absence of residual disease. No clinical trial has shown clear evidence of clinical benefit of this extended treatment. We have explored the economic impact of this practice in Spain. Spanish neuro-oncologists completed a questionnaire on the clinical management of glioblastomas in their centers. Based on their responses and on available clinical and demographic data, we estimated the number of patients who receive more than six cycles of temozolomide and calculated the cost of this extended treatment. Temozolomide treatment is continued for more than six cycles by 80.5 % of neuro-oncologists: 44.4 % only if there is residual disease; 27.8 % for 12 cycles even in the absence of residual disease; and 8.3 % until progression. Thus, 292 patients annually will continue treatment beyond six cycles in spite of a lack of clear evidence of clinical benefit. Temozolomide is covered by the National Health Insurance System, and the additional economic burden to society of this extended treatment is nearly 1.5 million euros a year. The optimal duration of adjuvant temozolomide treatment merits investigation in a clinical trial due to the economic consequences of prolonged treatment without evidence of greater patient benefit.

  14. Why evidence-based medicine failed in patient care and medicine-based evidence will succeed.

    Horwitz, Ralph I; Singer, Burton H

    2017-04-01

    Evidence-based medicine (EBM) has succeeded in strengthening the evidence base for population medicine. Where EBM has failed is in answering the practicing doctor's question of what a likely outcome would be when a given treatment is administered to a particular patient with her own distinctive biological and biographical (life experience) profile. We propose Medicine-based evidence (MBE), based on the profiles of individual patients, as the evidence base for individualized or personalized medicine. MBE will build an archive of patient profiles using data from all study types and data sources, and will include both clinical and socio-behavioral information. The clinician seeking guidance for the management of an individual patient will start with the patient's longitudinal profile and find approximate matches in the archive that describes how similar patients responded to a contemplated treatment and alternative treatments.

    2017-09-01

    Evidence-based medicine allows veterinarians to practice high-quality medicine, because the basis for all decision making is quantitative, objective, and reproducible. Case reports and case series are limited in their scope and application. Cross-sectional studies, likewise, cannot provide answers to specific variable testing with a temporal application. It is essential for the reptile specialty to expand into case-control studies, cohort studies, and experimental/intervention studies. Unfortunately, much of the reptile literature remains limited to descriptive studies. This article reviews current evidence-based topics in reptile medicine and shares how everyone practicing in the field can contribute to improving this specialty. Copyright © 2017 Elsevier Inc.

  17. Evidence-based hypnotherapy for depression.

    Science.gov (United States)

    Alladin, Assen

    2010-04-01

    Cognitive hypnotherapy (CH) is a comprehensive evidence-based hypnotherapy for clinical depression. This article describes the major components of CH, which integrate hypnosis with cognitive-behavior therapy as the latter provides an effective host theory for the assimilation of empirically supported treatment techniques derived from various theoretical models of psychotherapy and psychopathology. CH meets criteria for an assimilative model of psychotherapy, which is considered to be an efficacious model of psychotherapy integration. The major components of CH for depression are described in sufficient detail to allow replication, verification, and validation of the techniques delineated. CH for depression provides a template that clinicians and investigators can utilize to study the additive effects of hypnosis in the management of other psychological or medical disorders. Evidence-based hypnotherapy and research are encouraged; such a movement is necessary if clinical hypnosis is to integrate into mainstream psychotherapy.

    The purpose of this review is to determine the effectiveness of 2 separate modalities, digital mammography (DM) and magnetic resonance imaging (MRI), relative to film mammography (FM), in the screening of women asymptomatic for breast cancer. A third analysis assesses the effectiveness and safety of the combination of MRI plus mammography (MRI plus FM) in screening of women at high risk. An economic analysis was also conducted. How does the sensitivity and specificity of DM compare to FM?How does the sensitivity and specificity of MRI compare to FM?How do the recall rates compare among these screening modalities, and what effect might this have on radiation exposure? What are the risks associated with radiation exposure?How does the sensitivity and specificity of the combination of MRI plus FM compare to either MRI or FM alone?What are the economic considerations? The effectiveness of FM with respect to breast cancer mortality in the screening of asymptomatic average- risk women over the age of 50 has been established. However, based on a Medical Advisory Secretariat review completed in March 2006, screening is not recommended for women between the ages of 40 and 49 years. Guidelines published by the Canadian Task Force on Preventive Care recommend mammography screening every 1 to 2 years for women aged 50 years and over, hence, the inclusion of such women in organized breast cancer screening programs. In addition to the uncertainty of the effectiveness of mammography screening from the age of 40 years, there is concern over the risks associated with mammographic screening for the 10 years between the ages of 40 and 49 years. The lack of effectiveness of mammography screening starting at the age of 40 years (with respect to breast cancer mortality) is based on the assumption that the ability to detect cancer decreases with increased breast tissue density. As breast density is highest in the premenopausal years (approximately 23% of postmenopausal and 53% of

    Full Text Available Morphea is a rare fibrosing disorder of the skin. Evidence-based treatment strategies in morphea are lacking. This review summarizes the available data on morphea treatment and provides therapeutic strategies based on morphea subtypes. The Cochrane Library, Medline and Embase from inception until May of 2011 were searched using the key words "morphea" and "morphea treatment." Reference lists of the resultant articles, as well as relevant reviews, were also searched. This review focuses on randomized controlled trials, prospective interventional trials without controls and retrospective reviews with greater than five subjects.

  1. The application of probability analysis in evidence evaluation

    Directory of Open Access Journals (Sweden)

    Feješ Ištvan

    2014-01-01

    Full Text Available The paper is divided into three larger parts. In the introductory part the author reminds us that the application of mathematics to assess the evidence is not a substantially new idea. Inquisition procedures prescribed the legal assessment of evidence that consisted of primitive mechanical adding and subtracting the available evidence. However, modern mathematical methods that can be used for assessing evidence are far more sophisticated, and are based on probability analysis and computer technology. In the second part the paper deals with some possibilities of applying the probability analysis to evaluate evidence. It particularly tackles the potential of the Bayes' theorem of conditional probability in evidence assessment. The third part is the conclusion in which the author emphasizes that scientific progress is extremely fast and that mathematics will enter even more into courtrooms and thus progressively increase the exact elements of the now primarily subjective process of evidence evaluation. It particularly emphasizes the advantages of Bayesian analysis, but it warns that the results of this method are only one' mathematical truth', and that interpretation is the key.

  2. Evidence-based ethics? On evidence-based practice and the "empirical turn" from normative bioethics.

    Science.gov (United States)

    Goldenberg, Maya J

    2005-11-08

    The increase in empirical methods of research in bioethics over the last two decades is typically perceived as a welcomed broadening of the discipline, with increased integration of social and life scientists into the field and ethics consultants into the clinical setting, however it also represents a loss of confidence in the typical normative and analytic methods of bioethics. The recent incipiency of "Evidence-Based Ethics" attests to this phenomenon and should be rejected as a solution to the current ambivalence toward the normative resolution of moral problems in a pluralistic society. While "evidence-based" is typically read in medicine and other life and social sciences as the empirically-adequate standard of reasonable practice and a means for increasing certainty, I propose that the evidence-based movement in fact gains consensus by displacing normative discourse with aggregate or statistically-derived empirical evidence as the "bottom line". Therefore, along with wavering on the fact/value distinction, evidence-based ethics threatens bioethics' normative mandate. The appeal of the evidence-based approach is that it offers a means of negotiating the demands of moral pluralism. Rather than appealing to explicit values that are likely not shared by all, "the evidence" is proposed to adjudicate between competing claims. Quantified measures are notably more "neutral" and democratic than liberal markers like "species normal functioning". Yet the positivist notion that claims stand or fall in light of the evidence is untenable; furthermore, the legacy of positivism entails the quieting of empirically non-verifiable (or at least non-falsifiable) considerations like moral claims and judgments. As a result, evidence-based ethics proposes to operate with the implicit normativity that accompanies the production and presentation of all biomedical and scientific facts unchecked. The "empirical turn" in bioethics signals a need for reconsideration of the methods used

  3. Evaluation Considerations for Secondary Uses of Clinical Data: Principles for an Evidence-based Approach to Policy and Implementation of Secondary Analysis.

    2017-08-01

    Objectives: To set the scientific context and then suggest principles for an evidence-based approach to secondary uses of clinical data, covering both evaluation of the secondary uses of data and evaluation of health systems and services based upon secondary uses of data. Method: Working Group review of selected literature and policy approaches. Results: We present important considerations in the evaluation of secondary uses of clinical data from the angles of governance and trust, theory, semantics, and policy. We make the case for a multi-level and multi-factorial approach to the evaluation of secondary uses of clinical data and describe a methodological framework for best practice. We emphasise the importance of evaluating the governance of secondary uses of health data in maintaining trust, which is essential for such uses. We also offer examples of the re-use of routine health data to demonstrate how it can support evaluation of clinical performance and optimize health IT system design. Conclusions: Great expectations are resting upon "Big Data" and innovative analytics. However, to build and maintain public trust, improve data reliability, and assure the validity of analytic inferences, there must be independent and transparent evaluation. A mature and evidence-based approach needs not merely data science, but must be guided by the broader concerns of applied health informatics. Georg Thieme Verlag KG Stuttgart.

    2015-08-01

    Cellulite is a multifactorial condition that is present in 80-90 % of post-pubertal women. Despite its high prevalence, it remains a major cosmetic concern for women. A wide range of products and treatments for cellulite reduction is available; however, no systematic review has been performed so far to evaluate the efficacy of the available treatment options for cellulite. The objective of this review is to provide a systematic evaluation of the scientific evidence of the efficacy of treatments for cellulite reduction. This systematic review followed the PRISMA guidelines for reporting systematic reviews and meta-analyses. Only original articles in English or German reporting data on the efficacy of cellulite treatments from in vivo human studies were considered. In total, 67 articles were analyzed for the following information: therapy, presence of a control group, randomization, blinding, sample size, description of statistical methods, results, and level of evidence. Most of the evaluated studies, including laser- and light-based modalities, radiofrequency, and others had important methodological flaws; some did not use cellulite severity as an endpoint or did not provide sufficient statistical analyses. Of the 67 studies analyzed in this review, only 19 were placebo-controlled studies with randomization. Some evidence for potential benefit was only seen for acoustic wave therapy (AWT) and the 1440 nm Nd:YAG minimally invasive laser. This article provides a systematic evaluation of the scientific evidence of the efficacy of treatment for cellulite reduction. No clear evidence of good efficacy could be identified in any of the evaluated cellulite treatments.

    Cell phone use and texting are prevalent within society and have thus pervaded the driving population. This technology is a growing concern within the confines of distracted driving, as all diversions from attention to the road have been shown to increase the risk of crashes. Adolescent, inexperienced drivers, who have the greatest prevalence of texting while driving, are at a particularly higher risk of crashes because of distraction. Members of the Injury Control Violence Prevention Committee of the Eastern Association for the Surgery of Trauma performed a PubMed search of articles related to distracted driving and cell phone use as a distractor of driving between 2000 and 2013. A total of 19 articles were found to merit inclusion as evidence in the evidence-based review. These articles provided evidence regarding the relationship between distracted driving and crashes, cell phone use contributing to automobile accidents, and/or the relationship between driver experience and automobile accidents. (Adjust methods/results sections to the number of articles that correctly corresponds to the number of references, as well as the methodology for reference inclusion.) Based on the evidence reviewed, we can recommend the following. All drivers should minimize all in-vehicle distractions while on the road. All drivers should not text or use any touch messaging system (including the use of social media sites such as Facebook and Twitter) while driving. Younger, inexperienced drivers should especially not use cell phones, texting, or any touch messaging system while driving because they pose an increased risk for death and injury caused by distractions while driving.

    2011-01-01

    Full Text Available AbstractPurpose: The objective of the study was to compare a traditionally structured journal club with an evidence based structured journal club during an advanced clinical pharmacy rotation and to determine the best utilization that aligns with recent changes to the pharmacy school accreditation standards.Methods: The study included 21 students who completed journal club utilizing the traditional journal club format and 24 students who utilized an evidence based journal club format. Background characteristics, student reported beliefs, and mean critical evaluation skills scores were evaluated and compared in each group.Results: There were no statistically significant differences between the two cohorts in mean overall percentage grade for the activity. Students in the traditional cohort received significantly higher grades for the Study Analysis and Critique section (90.97 + 12.18 versus 81.25 + 11.18, P=0.01 as well as for the Preparedness section (96.11 + 8.03 versus 85.0 + 17.13, P=0.002. Students in the evidence based cohort received statistically superior grades for the Presentation Skills section (96.43 + 6.39 versus 82.47 + 14.12, P=0.0004.Conclusion: An evidence based journal club is a reasonable and effective alternative to the traditionally structured journal club when the primary objective is to assist students in understanding evidence based concepts and to apply current literature to clinical practice.

    2017-12-01

    Raynaud's phenomenon (RP) is relevant to the rheumatologist because it may signify an underlying connective tissue disease and also because it can be very challenging to treat, especially when it has progressed to digital ulceration or critical ischaemia. This review article discusses diagnosis (does this patient have an underlying connective tissue disease?), including the role for nailfold capillaroscopy, and treatment. Management of 'uncomplicated' RP is first described and then treatment of RP complicated by progression to digital ulceration or critical ischaemia, highlighting recent advances (including phosphodiesterase type 5 inhibition, and endothelin 1 receptor antagonism) and the evidence base underpinning these. Possible future therapies are briefly discussed.

    2017-09-01

    Because most research on rabbit husbandry, welfare, and nutrition was performed on production animals, evidence for best practices in pet rabbits is scarce, and guidelines must be based on transfer of results, deduction, and common sense. Rabbits benefit from being kept with at least one conspecific; from large enclosures and multistory hutches; from drinking water offered ad libitum in open dish drinker systems; and from receiving hay ad libitum, with restricted amounts of fresh grass, herbs, or green leafy vegetables, and a high-fiber complete diet. Offering hay ad libitum bears several advantages and should be considered a matter of course. Copyright © 2017 Elsevier Inc. All rights reserved.

    Learning to practice EBM provides physicians with the tools needed to overcome some of the common barriers they face when trying to use the medical literature to solve patient problems. It does require a change in attitude and behavior and is likely to be met with some resistance. Understanding the learners' stage of behavior change is likely to facilitate educational intervention. Behavior change does not occur unless physicians are convinced of the benefits of practicing EBM. Easy access to evidence-based summaries facilitates the use of high-quality evidence. Developing the ability to access information from the medical literature, critically appraising it, and applying it to patient care requires skills that need to be taught. Most practicing physicians were not taught these skills in medical school. Excellent resources are available from which to learn and teach EBM. Multiple exposures using a variety of formats are most effective. Finally, a tool to evaluate the acquisition of knowledge and skills needed to practice EBM recently has been validated. Despite ongoing challenges, learning and teaching EBM has never been easier and each year brings new and better tools to help practitioners and educators use the best available evidence. Box 2 lists suggestions for getting started.

    2011-01-01

    Chronic constipation is a common condition seen in family practice among the elderly and women. There is no consensus regarding its exact definition, and it may be interpreted differently by physicians and patients. Physicians prescribe various treatments, and patients often adopt different over-the-counter remedies. Chronic constipation is either caused by slow colonic transit or pelvic floor dysfunction, and treatment differs accordingly. To update our knowledge of chronic constipation and its etiology and best-evidence treatment, information was synthesized from articles published in PubMed, EMBASE, and Cochrane Database of Systematic Reviews. Levels of evidence and recommendations were made according to the Strength of Recommendation taxonomy. The standard advice of increasing dietary fibers, fluids, and exercise for relieving chronic constipation will only benefit patients with true deficiency. Biofeedback works best for constipation caused by pelvic floor dysfunction. Pharmacological agents increase bulk or water content in the bowel lumen or aim to stimulate bowel movements. Novel classes of compounds have emerged for treating chronic constipation, with promising clinical trial data. Finally, the link between senna abuse and colon cancer remains unsupported. Chronic constipation should be managed according to its etiology and guided by the best evidence-based treatment.

  15. Content analysis of UK newspaper and online news representations of women's and men's 'binge' drinking: a challenge for communicating evidence-based messages about single-episodic drinking?

    2016-12-27

    In the UK, men's alcohol-related morbidity and mortality still greatly exceeds women's, despite an increase in women's alcohol consumption in recent decades. New UK alcohol guidelines introduce gender-neutral low-risk alcohol consumption guidance. This study explores how UK newspaper and online news represent women's and men's 'binge' drinking to identify opportunities to better align reporting of harmful drinking with evidence. Quantitative and qualitative content analysis of 308 articles published in 7 UK national newspapers and the BBC News website between 1 January 2012 and 31 December 2013. Articles associated women with 'binge' drinking more frequently than men, and presented women's drinking as more problematic. Men were more frequently characterised as violent or disorderly, while women were characterised as out of control, putting themselves in danger, harming their physical appearance and burdening men. Descriptions of female 'binge' drinkers' clothing and appearance were typically moralistic. The UK news media's disproportionate focus on women's 'binge' drinking is at odds with epidemiological evidence, may reproduce harmful gender stereotypes and may obstruct public understandings of the gender-neutral weekly consumption limits in newly proposed alcohol guidelines. In order to better align reporting of harmful drinking with current evidence, public health advocates may engage with the media with a view to shifting media framing of 'binge' drinking away from specific groups (young people; women) and contexts (public drinking) and towards the health risks of specific drinking behaviours, which affect all groups regardless of context.

  17. Ethical reflections on Evidence Based Medicine

    Directory of Open Access Journals (Sweden)

    S. Corrao

    2013-05-01

    Full Text Available BACKGROUND According to Potter’s point of view, medical ethics is the science of survival, a bridge between humanistic and scientific culture. The working out of judgements on right or wrong referred to the human being are studied by this science. Methodological quality is fundamental in clinical research, and several technical issues are of paramount importance in trying to answer to the final question “what is the true, the right thing?”. We know they are essential aspects as in medical ethics as in evidence based practice. AIM OF THE STUDY The aim of this paper is to talk about relationships and implications between ethical issues and Evidence Based Medicine (EBM. DISCUSSION EBM represents a new paradigm that introduces new concepts to guide medical-decision making and health-care planning. Its principles are deeply rooted in clinical research methodology since information are derived from sound studies of strong quality. Health-care professionals have to deal with methodological concepts for critical appraisal of literature and implementation of evidences in clinical practice and healthcare planning. The central role of EBM in medical ethics is obvious, but a risk could be possible. The shift from Hippocratic point of view to community-centred one could lose sight of the centrality of the patient. CONCLUSION Both EBM principles and the needs to adequately response to economic restrictions urge a balance between individual and community ethics. All this has to represent an opportunity to place the patient at the centre of medical action considering at the same time community ethics as systemic aim, but without forgetting the risk that economic restrictions push towards veterinary ethics where herd is central and individual needs do not exist.

  18. Evidence-based standard care of malignant glioma

    International Nuclear Information System (INIS)

    Shinoda, Jun; Yano, Hirohito; Sakai, Noboru

    2004-01-01

    The amount of scientific evidence regarding therapy for primary cases of glioblastoma and anaplastic astrocytoma is small compared with that for malignant tumors in other organs, and recommended therapeutic strategies derived from this evidence are not diverse. Evidence-based standard care of these tumors is very limited. At this moment, the benchmark treatment for these malignant gliomas is gross resection of the tumor bulk followed by local external beam radiotherapy (50-60 Gy) in combination with nitrosourea-based chemotherapy. Additional stereotactic radiosurgery or other strategies for localized therapeutic boosting have also been recommended. However, the clinical outcomes obtained through these standard treatments are unfortunately not always satisfactory. Novel therapeutic strategies for malignant gliomas are expected to develop and we hope that some scientific evidence would emerge from clinical trials using these novel strategies. New scientific evidence for practical and novel treatments appropriate for patients with malignant gliomas may come to be available as the evaluation of patients' quality of life is used as an end point for the analysis of clinical results, in addition to the commonly used survival analysis.

    2008-09-01

    Full Text Available I love food. I love cooking, baking, testing, and eating. I read about food preparation, food facts, and food service. Over the years I’ve developed my fair share of knowledge about cooking and I’m a decent cook, but I’m no chef. I guess I’m what you’d call a “foodie”. However, I have the good fortune to have a friend who is a chef and owns one of the best, and certainly the most innovative, restaurants in town. During this summer I hosted a cooking class in my home for my family with my chef friend as instructor. The Tex-Mex barbecue theme was a big hit (you can contact me for recipes, if you like, but much more fascinating was the explanation of the science behind the cooking. It turns out that there is a term for this: molecular gastronomy. Another term, and hence the genesis of my “Eureka!” moment of the summer, is evidence based cooking. Good cooking is not just following a recipe (not all of which are evidence based but at its best is the culmination of heaps of tested information regarding why and how chemical and environmental factors work together to result in a gastronomical delight. For example, will brining or marinating a pork chop make it moister? And, if brining, what temperature should the water be, how long should it soak, and how much salt is needed? Why does pounding meat increase its tenderness? What will keep guacamole from browning better – the pit or lime juice? What does baking soda do in a chocolate cake? Eggs or no eggs in fresh pasta? Like most librarians, I tend not to take information at face value. I want to know where information comes from and whether or not it is valid, based on specific factors. I’ve come to notice that evidence based, or evidence informed, practice is everywhere and has a tremendous impact on our lives. Why do you rotate the tires on your car? Evidence shows that the front tires wear more quickly (think about all those 3-pointturns, the braking, etc and therefore

    Moeller, M R; Fey, P; Sachs, H

    1993-12-01

    Because hair analysis can be used for the determination of drug use months after drug consumption, hair analysis data can often act as important and even decisive evidence in the courtroom. More recently developed GC/MS methods offer excellent sensitivity and can make the distinction between chronic heroin and codeine use, which was not possible earlier with radioimmunoassay techniques. From more than a thousand hair analyses, the morphine/codeine ratios necessary to determine heroin use were set at 5:1 for low morphine concentrations (< 1 ng/mg hair) and 2:1 for concentrations above 1 ng/mg hair. The distinction can be further focused with the additional analysis of the metabolite monoacetylmorphine (MAM). As can be seen from several case examples, hair analysis cannot pinpoint an exact date of opiate use, but it can be used to validate or invalidate a subject's statement concerning his/her drug consumption. Interpretations should always be made cautiously. Ranges, means and medians are also listed for amphetamine, cocaine and cannabis and work is under way to draw similar safety guidelines for these drugs.

    2013-01-01

    This preceptorship course case study employed an evidence-based reflective teaching practice perspective based on a nursing process framework to develop, implement, and evaluate assignment efficacy directly related to course objectives. Journaling and article analysis had been used to assess development of role socialization, critical thinking, and self-reflective practice. These activities were found to be ineffective; new assignments were needed to address essential issues and allow for evaluation of assignment efficacy. Based upon contextual constructivism, four assignments were developed focused on learning goals, nursing skills, assumptions/biases, and role socialization.Assignment efficacy was evaluated via anonymous exploratory surveys. Student reports identified that assignments met learning outcomes. Methods for improvement in instructional practice were identified and revisions made. Participation in evidence-based reflective teaching practice can enhance reflective practice in students through appropriate assignment development, advancing the discipline of nursing education.

  4. Evidence-based policymaking is not like evidence-based medicine, so how far should you go to bridge the divide between evidence and policy?

    Cairney, Paul; Oliver, Kathryn

    2017-04-26

    There is extensive health and public health literature on the 'evidence-policy gap', exploring the frustrating experiences of scientists trying to secure a response to the problems and solutions they raise and identifying the need for better evidence to reduce policymaker uncertainty. We offer a new perspective by using policy theory to propose research with greater impact, identifying the need to use persuasion to reduce ambiguity, and to adapt to multi-level policymaking systems.We identify insights from secondary data, namely systematic reviews, critical analysis and policy theories relevant to evidence-based policymaking. The studies are drawn primarily from countries such as the United States, United Kingdom, Canada, Australia and New Zealand. We combine empirical and normative elements to identify the ways in which scientists can, do and could influence policy.We identify two important dilemmas, for scientists and researchers, that arise from our initial advice. First, effective actors combine evidence with manipulative emotional appeals to influence the policy agenda - should scientists do the same, or would the reputational costs outweigh the policy benefits? Second, when adapting to multi-level policymaking, should scientists prioritise 'evidence-based' policymaking above other factors? The latter includes governance principles such the 'co-production' of policy between local public bodies, interest groups and service users. This process may be based primarily on values and involve actors with no commitment to a hierarchy of evidence.We conclude that successful engagement in 'evidence-based policymaking' requires pragmatism, combining scientific evidence with governance principles, and persuasion to translate complex evidence into simple stories. To maximise the use of scientific evidence in health and public health policy, researchers should recognise the tendency of policymakers to base judgements on their beliefs, and shortcuts based on their emotions

    2011-03-01

    Many neurodevelopmental disorders affect early brain development in ways that are still poorly understood; yet, these disorders can place an enormous toll on patients, families, and society as a whole and affect all aspects of daily living for patients and their families. We describe a pragmatic, evidence-based framework for engaging in empiric ethics inquiry for a large consortium of researchers in neurodevelopmental disorders and provide relevant case studies of pragmatic neuroethics. The 3 neurodevelopmental disorders that are at the focus of our research, cerebral palsy (CP), autism spectrum disorder (ASD), and fetal alcohol spectrum disorder (FASD), bring unique and intersecting challenges of translating ethically research into clinical care for children and neonates. We identify and discuss challenges related to health care delivery in CP; neonatal neurological decision making; alternative therapies; and identity, integrity, and personhood.

    The internet is an easy and always accessible source of information for cancer patients. The aim of our study was to evaluate the information provided on German websites. We developed an instrument based on criteria for patient information from the German Network for Evidence-based Medicine, the Agency for Quality in Medicine, HONcode, DISCERN, and the afgis. We simulated a patient's search and derived the websites for evaluation. We analyzed the visibility of each website and evaluated the websites using the developed instrument. We analyzed 77 websites. The highest visibility index was shown by 4 profit websites. Websites from professional societies and self-help groups have low rankings. Concerning quality, websites from non-profit providers and self-help groups are on top. Websites with a profit interest have the lowest average score. A discrepancy exists between the visibility and the quality of the analyzed websites. With the internet becoming an important source of information on cancer treatments for patients, this may lead to false information and wrong decisions. We provide a list of suggestions as to how this risk may be reduced by complementary information from the physician and from trustworthy websites. © 2015 S. Karger GmbH, Freiburg.

    Evidence-based medicine is the conscientious, explicit, and judicious use of current best evidence in making decisions about the care of individual patients. .. by best available external clinical evidence we mean clinically relevant research.' Health care reform authorized by the Affordable Care Act is based on the belief that evidence-based practice (EBP) generates cost savings due to the delivery of more effective care.2 Medical librarians, skilled in identifying appropriate resources and working with multiple complex interfaces, can support clinicians' efforts to practice evidence based medicine by providing time and expertise in articulating the clinical question and identifying the best evidence.

    Recent scientific debate has focused on the potential for inhaled formaldehyde to cause lymphohematopoietic cancers, particularly leukemias, in humans. The concern stems from certain epidemiology studies reporting an association, although particulars of endpoints and dosimetry are inconsistent across studies and several other studies show no such effects. Animal studies generally report neither hematotoxicity nor leukemia associated with formaldehyde inhalation, and hematotoxicity studies in humans are inconsistent. Formaldehyde's reactivity has been thought to preclude systemic exposure following inhalation, and its apparent inability to reach and affect the target tissues attacked by known leukemogens has, heretofore, led to skepticism regarding its potential to cause human lymphohematopoietic cancers. Recently, however, potential modes of action for formaldehyde leukemogenesis have been hypothesized, and it has been suggested that formaldehyde be identified as a known human leukemogen. In this article, we apply our hypothesis-based weight-of-evidence (HBWoE) approach to evaluate the large body of evidence regarding formaldehyde and leukemogenesis, attending to how human, animal, and mode-of-action results inform one another. We trace the logic of inference within and across all studies, and articulate how one could account for the suite of available observations under the various proposed hypotheses. Upon comparison of alternative proposals regarding what causal processes may have led to the array of observations as we see them, we conclude that the case fora causal association is weak and strains biological plausibility. Instead, apparent association between formaldehyde inhalation and leukemia in some human studies is better interpreted as due to chance or confounding. PMID:21635189

    With the rapid discovery of prognostic and predictive molecular parameters for glioma, the status of histopathology in the diagnostic process should be scrutinized. Our project aimed to construct a diagnostic algorithm for gliomas based on molecular and histologic parameters with independent prognostic values. The pathology slides of 636 patients with gliomas who had been included in EORTC 26951 and 26882 trials were reviewed using virtual microscopy by a panel of six neuropathologists who independently scored 18 histologic features and provided an overall diagnosis. The molecular data for IDH1, 1p/19q loss, EGFR amplification, loss of chromosome 10 and chromosome arm 10q, gain of chromosome 7, and hypermethylation of the promoter of MGMT were available for some of the cases. The slides were divided in discovery (n = 426) and validation sets (n = 210). The diagnostic algorithm resulting from analysis of the discovery set was validated in the latter. In 66% of cases, consensus of overall diagnosis was present. A diagnostic algorithm consisting of two molecular markers and one consensus histologic feature was created by conditional inference tree analysis. The order of prognostic significance was: 1p/19q loss, EGFR amplification, and astrocytic morphology, which resulted in the identification of four diagnostic nodes. Validation of the nodes in the validation set confirmed the prognostic value (P < .001). We succeeded in the creation of a timely diagnostic algorithm for anaplastic glioma based on multivariable analysis of consensus histopathology and molecular parameters. © 2015 by American Society of Clinical Oncology.

    Bronchiolitis is the leading cause of lower respiratory tract infection in infants and produces significant morbidity. Limited progress has been made in the treatment of this disease and, in many cases, the therapy employed is controversial and mainly based on general recommendations and not on evidence-based strategies. This report uses evidence-based methodology to provide a critical review of the data available on the treatment of acute bronchiolitis (understood as the first episode of respiratory syncytial virus bronchiolitis in a previously healthy infant). After this analysis, we conclude that the only justifiable therapeutic interventions in these patients are supportive treatment, nebulized epinephrine and mechanical ventilation. Other therapies such us physiotherapy, nebulization, heliox, anticholinergics or exogenous surfactant, among others, require further randomized controlled trials to determine their utility. No evidence supports the routine use of corticosteroids, beta-adrenergic drugs, antibiotics, immunoglobulins, interferon, vitamin A or ribavirin in these patients. Finally, we consider that a national consensus review for the implementation of evidence-based clinical practical guidelines on the management of acute bronchiolitis would be of great interest.

    2015-01-01

    Background Magnetic resonance–guided high-intensity focused ultrasound (MRgHIFU) is a noninvasive uterine-preserving treatment alternative to hysterectomy for women with symptomatic uterine leiomyomas (fibroids). Uterine fibroids commonly occur, have a broad impact on women's health and lifestyle, continue to be the main indication for hysterectomy, and represent a costly public health burden. Objectives The objectives of the analysis were to evaluate patients’ eligibility for MRgHIFU treatment of symptomatic uterine fibroids and the technical success, safety, effectiveness, and durability of this treatment. The review also compared the safety and effectiveness of MRgHIFU with other minimally invasive uterine-preserving treatments and surgeries for uterine fibroids. Methods A literature search was performed on March 27, 2014, using Ovid MEDLINE, Ovid MEDLINE In-Process and Other Non-Indexed Citations, Ovid EMBASE, EBSCO Cumulative Index to Nursing & Allied Health Literature (CINAHL), and EBM Reviews, for studies published from January 1, 2000, to March 27, 2014. Results The evidence review identified 2 systematic reviews, 2 RCTs, 45 cohort study reports, and 19 case reports involving HIFU treatment of symptomatic uterine fibroids. Eligibility for MRgHIFU treatment was variable, ranging from 14% to 74%. In clinical cohort studies involving 1,594 patients, 26 major complications (1.6%) were reported. MRgHIFU resulted in statistically and clinically significant reductions in fibroid-related symptoms in studies conducted in 10 countries, although few involved follow-up longer than 1 year. Retreatment rates following MRgHIFU were higher in early clinical studies involving regulated restrictions in the extent of fibroid ablation than in later reports involving near-complete ablation. Emergent interventions, however, were rare. Although a desire for fertility was an exclusion criteria for treatment, spontaneous term pregnancies did occur following HIFU. There were no

    A reduction in tissue tolerance promotes the development of pressure ulcers (PUs) and incontinence-associated dermatitis (IAD). To determine the cost-effectiveness and efficacy of evidence-based (EB) nursing interventions on increasing tissue tolerance by maintaining tissue integrity. The study involved 154 patients in two intensive care units (77 patients, control group; 77 patients, intervention group). Data were collected using the following: patient characteristics form, Braden PU risk assessment scale, tissue integrity monitoring form, PU identification form, IAD and severity scale, and a cost table of the interventions. Patients in the intervention group were cared for by nurses trained in the use of the data collection tools and in EB practices to improve tissue tolerance. Routine nursing care was given to the patients in the control group. The researcher observed all patients in terms of tissue integrity and recorded the care-related costs. Deterioration of tissue integrity was observed in 18.2% patients in the intervention group compared to 54.5% in the control group (p prevention in the intervention and control groups was X¯ = $204.34 ± 41.07 and X¯ = $138.90 ± 1.70, respectively. It is recommended that EB policies and procedures are developed to improve tissue tolerance by maintaining tissue integrity. Although the cost of EB preventive initiatives is relatively high compared to those that are not EB, the former provide a significant reduction in the prevalence of tissue integrity deterioration. © 2017 Sigma Theta Tau International.

    Continued debate about the relative value of fidelity versus adaptation, and lack of clarity about the meaning of fidelity, raise concerns about how frontline service providers resolve similar issues in their daily practice. We use SISTA (‘Sisters Informing Sisters on Topics about acquired immune deficiency syndrome’), an evidence-based human immunodeficiency virus (HIV) prevention intervention for African American women, to understand how facilitators and program directors interpret and enact implementation fidelity with the need for adaptation in real-world program delivery. We conducted 22 in-depth, semi-structured interviews with service providers from four agencies implementing SISTA. Facilitators valued their skills as group leaders and ability to emotionally engage participants as more critical to program effectiveness than delivering the intervention with strict fidelity. Consequently, they saw program manuals as guides rather than static texts that should never be changed and, moreover, viewed the prescriptive nature of manuals as undermining their efforts to fully engage with participants. Our findings suggest that greater consideration should be given to understanding the role of facilitators in program effectiveness over and above the question of whether they implement the program with fidelity. Moreover, training curricula should provide facilitators with transferable skills through general facilitator training rather than only program-specific or manual-specific training. PMID:26944867

    Full Text Available ABSTRACT Objective: to verify the content evidence of a spectrographic analysis protocol. Methods: a methodological study in which five speech therapists who assessed the clarity and the relevance of the protocol were selected. The Content Validity Index (CVI was used to investigate the level of agreement among judges regarding overall aspects, items and domains of the protocol. Results: most judges considered the overall aspects of the protocol as comprehensive. As for clarity, 17 items showed an excellent content validity (CVI ≥ 0.78, three showed a good content validity (0.60 ≤ CVI ≤ 0.77 and two items were judged as poor (CVI ≤ 0.59. As for relevance, 19 items obtained an excellent content validity (CVI ≥ 0.78 and three had a good content validity (0.60 ≤ CVI ≤ 0.77. The judges suggested adding items related to vocal signal normality in all domains. After the analysis, 18 items required no reformulation, five items were added, three were reformulated and one was excluded. Conclusion: the proposed protocol was regarded as a comprehensive one. The items presented a good to excellent content validity as for clarity and relevance. After this validation step, the protocol ended up presenting 25 items distributed into five domains.

    Health-system barriers and facilitators associated with cardiovascular medication adherence have seldom been studied, particularly in low- and middle-income countries where uptake rates are poorest. This study sought to explore the major obstacles and facilitators to the use of evidence-supported medications for secondary prevention of cardiovascular disease using qualitative analysis in 2 diverse countries across multiple levels of their health care systems. A qualitative descriptive study approach was implemented in Hamilton, Ontario, Canada, and Delhi, India. A purposeful sample (n = 69) of 23 patients, 10 physicians, 2 nurse practitioners, 5 Department of Ayurveda, Yoga and Naturopathy, Unani, Siddha, and Homoeopathy physicians, 11 pharmacists, 3 nurses, 4 hospital administrators, 1 social worker, 3 nongovernmental organization workers, 2 pharmaceutical company representatives, and 5 policy makers participated in interviews in Hamilton, Ontario, Canada (n = 21), and Delhi, India (n = 48). All interviews were digitally recorded and transcribed followed by directed content analysis to summarize and categorize the interviews. Themes that emerged across the stakeholder groups included: medication counseling; monitoring adherence; medication availability; medication affordability and drug coverage; time restrictions; and task shifting. The depth of verbal medication counseling provided varied substantially between countries, with prescribers in India unable to convey relevant information about drug treatments due to time constraint and high patient load. Canadian patients reported drug affordability as a common issue and very few patients were familiar with government subsidized drug programs. In India, patients purchased medications out-of-pocket from private, community pharmacies to avoid long commutes, lost wages, and unavailability of medications from hospitals formularies. Task shifting medication-refilling and titration to nonphysician health workers was

    Researchers often struggle with the gap between efficacy and effectiveness in clinical research. To bridge this gap, the Community Healthcare for Asthma Management and Prevention of Symptoms (CHAMPS) study adapted an efficacious, randomized controlled trial that resulted in evidence-based asthma interventions in community health centers. Children (aged 5-12 years; N = 590) with moderate to severe asthma were enrolled from 3 intervention and 3 geographically/capacity-matched control sites in high-risk, low-income communities located in Arizona, Michigan, and Puerto Rico. The asthma intervention was tailored to the participant's allergen sensitivity and exposure, and it comprised 4 visits over the course of 1 year. Study visits were documented and monitored prospectively via electronic data capture. Asthma symptoms and health care utilization were evaluated at baseline, and at 6 and 12 months. A total of 314 intervention children and 276 control children were enrolled in the study. Allergen sensitivity testing (96%) and home environmental assessments (89%) were performed on the majority of intervention children. Overall study activity completion (eg, intervention visits, clinical assessments) was 70%. Overall and individual site participant symptom days in the previous 4 weeks were significantly reduced compared with control findings (control, change of -2.28; intervention, change of -3.27; difference, -0.99; P asthma in these high-need populations.

    Information literacy, the recognition of information required, and the development of skills for locating, evaluating, and effectively using relevant evidence is needed for evidence-based practice (EBP). The purpose of this study was to examine perianesthesia nurses' perception of searching skills and access to evidence sources. The design was a descriptive, exploratory survey. The sample consisted of ASPAN members (n = 64) and nonmembers (n = 64). The Information Literacy for Evidence-Based Nursing Practice instrument was used. Findings were that ASPAN members read more journal articles, were more proficient with computers, and used Cumulative Index to Nursing and Allied Health Literature (CINAHL) more frequently than nonmembers. The three top barriers to use of research were: lack of understanding of organization or structure of electronic databases, lack of skills to critique and/or synthesize the literature, and difficulty in accessing research materials. In conclusion, education is needed for critiquing literature and understanding electronic databases and research articles to promote EBP in perianesthesia areas. Copyright 2010.

    Full Text Available Two behavioral HIV prevention interventions for people who inject drugs (PWID infected with HIV include the Holistic Health Recovery Program for HIV+ (HHRP+, a comprehensive evidence-based CDC-supported program, and an abbreviated Holistic Health for HIV (3H+ Program, an adapted HHRP+ version in treatment settings. We compared the projected health benefits and cost-effectiveness of both programs, in addition to opioid substitution therapy (OST, to the status quo in the U.S.A dynamic HIV transmission model calibrated to epidemic data of current US populations was created. Projected outcomes include future HIV incidence, HIV prevalence, and quality-adjusted life years (QALYs gained under alternative strategies. Total medical costs were estimated to compare the cost-effectiveness of each strategy.Over 10 years, expanding HHRP+ access to 80% of PWID could avert up to 29,000 HIV infections, or 6% of the projected total, at a cost of $7,777/QALY gained. Alternatively, 3H+ could avert 19,000 infections, but is slightly more cost-effective ($7,707/QALY, and remains so under widely varying effectiveness and cost assumptions. Nearly two-thirds of infections averted with either program are among non-PWIDs, due to reduced sexual transmission from PWID to their partners. Expanding these programs with broader OST coverage could avert up to 74,000 HIV infections over 10 years and reduce HIV prevalence from 16.5% to 14.1%, but is substantially more expensive than HHRP+ or 3H+ alone.Both behavioral interventions were effective and cost-effective at reducing HIV incidence among both PWID and the general adult population; however, 3H+, the economical HHRP+ version, was slightly more cost-effective than HHRP+.

    The Strategic Group of Advisory Experts (SAGE) on immunization is an independent advisory committee with a mandate to advise the World Health Organization (WHO) on the development of vaccine and immunization related policies. SAGE working groups are established on a time-limited basis to review and provide evidence-based recommendations, together with their implications, for open deliberation and decision-making by SAGE. In making its recommendations, SAGE takes into consideration: the epidemiologic and clinical characteristics of the disease; vaccine and immunization characteristics; economic analysis; health system considerations; the existence of and interaction with other intervention and control strategies; costing and social impacts; and legal and ethical concerns. Since 1998, WHO has produced evidence-based vaccine position papers for use primarily by national public health officials and immunization programme managers. Since April 2006 all new or updated position papers have been based on SAGE recommendations. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach has been adopted by WHO and, since 2008, GRADE tables that rate the quality of evidence have been produced in support of key recommendations. SAGE previously expressed concern that GRADE was not ideally suited to many immunization-specific issues such as the vaccine population level effect and the inclusion of surveillance system data, particularly for vaccine safety. Extensive productive interactions with various advisory groups including the US Advisory Committee on Immunization Practices, the European Centres for Disease Control, the German Standing Committee on Vaccination (STIKO), WHO's Global Advisory Committee on Vaccine Safety and the GRADE working group resulted in key enhancements to accommodate vaccine-relevant evidence. This facilitated integration and acceptability of the GRADE approach in the development of immunization related SAGE and WHO

    Full Text Available Objective - In developing marketing strategies for the Business & Economics Library (BEL at the University of Illinois at Urbana-Champaign (UIUC, a survey was designed to answer the following questions: - Should BEL develop marketing strategies differently for East Asian business students? - What services do graduate business students want to receive from BEL? - With whom should BEL partner to increase visibility at the College of Business? Marketing research techniques were used to gather evidence upon which BEL could construct appropriate marketing strategies. Methods - A questionnaire was used with graduate business students enrolled at UIUC. The survey consisted of four categories of questions: 1 demographics, 2 assessment of current library services, 3 desired library services, and 4 research behavior. The data were analyzed using desriptive statistics and hypothesis testing to answer the three research questions. Results - East Asian business students showed similar assessment of current services as non-East Asian international business students. Survey results also showed the graduate business students had low awareness of current library services. The Business Career Services Office was identified as a co-branding partner for BEL to increase its visibility. Conclusion - A marketing research approach was used to help BEL make important strategic decisions before launching marketing campaigns to increase visibility to graduate business students at UIUC. As a result of the survey, a deeper understanding of graduate business students' expectations and assessment of library services was gained. Students' perceptions became a foundation that helped shape marketing strategies for BEL to increase its visibility at the College of Business. Creating marketing strategies without concrete data and analysis is a risky endeavor that librarians, not just corporate marketers, should avoid.

    In England the National Health Service (NHS) is not allowed to impose 'blanket bans' on treatments, but local commissioners produce lists of 'low value' procedures that they will normally not fund. Breast surgery is one example. However, evidence suggests that some breast surgery is clinically effective, with significant health gain. National guidelines indicate the circumstances under which breast surgery should be made available on the NHS, but there is widespread variation in their implementation.The purpose of this study was to explore the work practices of 'individual funding request' (IFR) panels, as they considered 'one-off' funding requests for breast surgery; examine how the notion of 'value' is dialogically constructed, and how decisions about who is deserving of NHS funding and who is not are accomplished in practice. We undertook ethnographic exploration of three IFR panels. We extracted all (22) breast surgery cases considered by these panels from our data set and progressively focused on three case discussions, one from each panel, covering the three main breast procedures.We undertook a microanalysis of the talk and texts arising from these cases, within a conceptual framework of interpretive policy analysis. Through an exploration of the symbolic artefacts (language, objects and acts) that are significant carriers of policy meaning, we identified the ways in which IFR panels create their own 'interpretive communities', within which deliberations about the funding of breast surgery are differently framed, and local decisions come to be justified. In particular, we demonstrated how each decision was contingent on [a] the evaluative accent given to certain words, [b] the work that documentary objects achieve in foregrounding particular concerns, and [c] the act of categorising. Meaning was constructed dialogically through local interaction and broader socio-cultural discourses about breasts and 'cosmetic' surgery. Despite the appeal of calls to tackle

    The purpose of this investigation is to determine the proportion of sports medicine studies that are labeled as Level I Evidence in 5 journals and compare the quality of surgical and nonsurgical studies using simple quality assessment tools (Consolidated Standards of Reporting Trials [CONSORT] and Jadad). By use of PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines over the prior 2 years in the top 5 (citation and impact factor based) sports medicine journals, only Level I Evidence studies were eligible for inclusion and were analyzed. All study types (therapeutic, prognostic, diagnostic, and economic) were analyzed. Study quality was assessed with the level of evidence, Jadad score, and CONSORT 2010 guidelines. Study demographic data were compared among journals and between surgical and nonsurgical studies by use of χ(2), 1-way analysis of variance, and 2-sample Z tests. We analyzed 190 Level I Evidence studies (10% of eligible studies) (119 randomized controlled trials [RCTs]). Therapeutic, nonsurgical, single-center studies from the United States were the most common studies published. Sixty-two percent of studies reported a financial conflict of interest. The knee was the most common body part studied, and track-and-field/endurance sports were the most common sports analyzed. Significant differences (P .05) were shown among journals based on the proportion of Level I studies or appropriate randomization. Significant strengths and limitations of RCTs were identified. This study showed that Level I Evidence and RCTs comprise 10% and 6% of contemporary sports medicine literature, respectively. Therapeutic, nonsurgical, single-center studies are the most common publications with Level I Evidence. Significant differences across sports medicine journals were found in study quality. Surgical studies appropriately described randomization, blinding, and patient enrollment significantly more than nonsurgical studies. Level I

    Finding robust brain substrates of mood disorders is an important target for research. The degree to which major depression (MDD) and bipolar disorder (BD) are associated with common and/or distinct patterns of volumetric changes is nevertheless unclear. Furthermore, the extant literature is heterogeneous with respect to the nature of these changes. We report a meta-analysis of voxel-based morphometry (VBM) studies in MDD and BD. We identified studies published up to January 2015 that compared grey matter in MDD (50 data sets including 4101 individuals) and BD (36 data sets including 2407 individuals) using whole-brain VBM. We used statistical maps from the studies included where available and reported peak coordinates otherwise. Group comparisons and conjunction analyses identified regions in which the disorders showed common and distinct patterns of volumetric alteration. Both disorders were associated with lower grey-matter volume relative to healthy individuals in a number of areas. Conjunction analysis showed smaller volumes in both disorders in clusters in the dorsomedial and ventromedial prefrontal cortex, including the anterior cingulate cortex and bilateral insula. Group comparisons indicated that findings of smaller grey-matter volumes relative to controls in the right dorsolateral prefrontal cortex and left hippocampus, along with cerebellar, temporal and parietal regions were more substantial in major depression. These results suggest that MDD and BD are characterised by both common and distinct patterns of grey-matter volume changes. This combination of differences and similarities has the potential to inform the development of diagnostic biomarkers for these conditions.

    Most textbooks contains messages relating to health. This profuse information requires analysis with regards to the quality of such information. The objective was to identify the scientific evidence on which the health messages in textbooks are based. The degree of evidence on which such messages are based was identified and the messages were subsequently classified into three categories: Messages with high, medium or low levels of evidence; Messages with an unknown level of evidence; and Messages with no known evidence. 844 messages were studied. Of this total, 61% were classified as messages with an unknown level of evidence. Less than 15% fell into the category where the level of evidence was known and less than 6% were classified as possessing high levels of evidence. More than 70% of the messages relating to "Balanced Diets and Malnutrition", "Food Hygiene", "Tobacco", "Sexual behaviour and AIDS" and "Rest and ergonomics" are based on an unknown level of evidence. "Oral health" registered the highest percentage of messages based on a high level of evidence (37.5%), followed by "Pregnancy and newly born infants" (35%). Of the total, 24.6% are not based on any known evidence. Two of the messages appeared to contravene known evidence. Many of the messages included in school textbooks are not based on scientific evidence. Standards must be established to facilitate the production of texts that include messages that are based on the best available evidence and which can improve children's health more effectively.

    Full Text Available Objective – This paper provides an overview of progress and developments surrounding evidence based practice in school librarianship, and seeks to provide a picture of current thinking about evidence based practice as it relates to the field. It addresses current issues and challenges facing the adoption of evidence based practice in school librarianship.Methods – The paper is based on a narrative review of a small but growing body of literature on evidence based practice in school librarianship, set within a broader perspective of evidence based education. In addition, it presents the outcomes of a collaborative process of input from 200 school libraries leaders collected at a School Library summit in 2007 specifically to address the emerging arena of evidence based practice in this field.Results – A holistic model of evidence based practice for school libraries is presented, centering on three integrated dimensions of evidence: evidence for practice, evidence in practice, and evidence of practice.Conclusion – The paper identifies key challenges ahead if evidence based school librarianship is to develop further. These include: building research credibility within the broader educational environment; the need for ongoing review and evaluation of the diverse body of research in education, librarianship and allied fields to make quality evidence available in ways that can enable practicing school librarians to build a culture of evidence based practice; development of tools, strategies, and exemplars to use to facilitate evidence based decision-making; and, ensuring that the many and diverse advances in education and librarianship become part of the practice of school librarianship.

  13. Strengths and Limitations of Evidence-Based Dermatology

    Williams, Hywel C

    2014-01-01

    The need for understanding and reflecting on evidence-based dermatology (EBD) has never been greater given the exponential growth of new external evidence to inform clinical practice. Like any other branch of medicine, dermatologists need to acquire new skills in constructing answerable questions, efficiently searching electronic bibliographic databases, and critically appraising different types of studies. Secondary summaries of evidence in the form of systematic reviews (SR), that is, reviews that are conducted in a systematic, unbiased and explicit manner, reside at the top of the evidence hierarchy, because they are less prone to bias than traditional expert reviews. In addition to providing summaries of the best external evidence, systematic reviews and randomized controlled trials (RCTs) are also powerful ways of identifying research gaps and ultimately setting the agenda of future clinical research in dermatology. But like any paradigm, EBD can have its limitations. Wrong application, misuse and overuse of EBD can have serious consequences. For example, mindless pooling together of data from dissimilar studies in a meta-analysis may render it a form of reductionism that does not make any sense. Similarly, even highly protocolised study designs such as SRs and RCTs are still susceptible to some degree of dishonesty and bias. Over-reliance on randomized controlled trials (RCT) may be inappropriate, as RCTs are not a good source for picking up rare but important adverse effects such as lupus syndrome with minocycline. A common criticism leveled against SRs is that these frequently conclude that there is lack of sufficient evidence to inform current clinical practice, but arguably, such a perception is grounded more on the interpretation of the SRs than anything else. The apparent absence of evidence should not paralyze the dermatologist to adopt a state of therapeutic nihilism. Poor primary data and an SR based on evidence that is not up-to-date are also

    Existing research postulates a variety of components that show an impact on utilization of technology-mediated mental health information systems (MHIS) and treatment outcome. Although researchers assessed the effect of isolated design elements on the results of Web-based interventions and the associations between symptom reduction and use of components across computer and mobile phone platforms, there remains uncertainty with regard to which components of technology-mediated interventions for mental health exert the greatest therapeutic gain. Until now, no studies have presented results on the therapeutic benefit associated with specific service components of technology-mediated MHIS for depression. This systematic review aims at identifying components of technology-mediated MHIS for patients with depression. Consequently, all randomized controlled trials comparing technology-mediated treatments for depression to either waiting-list control, treatment as usual, or any other form of treatment for depression were reviewed. Updating prior reviews, this study aims to (1) assess the effectiveness of technology-supported interventions for the treatment of depression and (2) add to the debate on what components in technology-mediated MHIS for the treatment of depression should be standard of care. Systematic searches in MEDLINE, PsycINFO, and the Cochrane Library were conducted. Effect sizes for each comparison between a technology-enabled intervention and a control condition were computed using the standard mean difference (SMD). Chi-square tests were used to test for heterogeneity. Using subgroup analysis, potential sources of heterogeneity were analyzed. Publication bias was examined using visual inspection of funnel plots and Begg's test. Qualitative data analysis was also used. In an explorative approach, a list of relevant components was extracted from the body of literature by consensus between two researchers. Of 6387 studies initially identified, 45 met all

  20. Metabolomics-based evidence of the hypoglycemic effect of Ge-Gen-Jiao-Tai-Wan in type 2 diabetic rats via UHPLC-QTOF/MS analysis.

    Ge-Gen-Jiao-Tai-Wan (GGJTW) formula, derived from traditional Chinese herbal medicine, is composed of Pueraria montana var. lobata (Willd.) Sanjappa & Pradeep (Ge-Gen in Chinese), Coptis chinensis Franch (Huang-Lian), and Cinnamomum cassia (L.) J. Presl (Rou-Gui). GGJTW is used for treatment of diabetes in China, reflecting the potent hypoglycemic effect of its ingredients. However, little is known of the hypoglycemic effect of GGJTW and the underlying metabolic mechanism. This study aimed to investigate the hypoglycemic effect of GGJTW in type 2 diabetic rats and the metabolic mechanism of action. Ultra high-performance liquid chromatography coupled with quadrupole-time-of-flight tandem mass spectrometry (UHPLC-QTOF/MS)-based metabolomics approach was used for monitoring hyperglycaemia induced by high-sugar high-fat fodder and streptozotocin (STZ), and the protective effect of GGJTW. Dynamic fasting blood glucose (FBG) levels, body weight, and biochemical parameters, including lipid levels, hepatic-renal function, and hepatic histopathology were used to confirm the hyperglycaemic toxicity and attenuation effects. An orthogonal partial least squared-discriminant analysis (OPLS-DA) approach highlighted significant differences in the metabolome of the healthy control, diabetic, and drug-treated rats. The metabolomics pathway analysis (MetPA) and Kyoto encyclopedia of genes and genomes (KEGG) database were used to investigate the underlying metabolic pathways. Metabolic profiling revealed 37 metabolites as the most potential biomarker metabolites distinguishing GGJTW-treated rats from model rats. Most of the metabolites were primarily associated with bile acid metabolism and lipid metabolism. The most critical pathway was primary bile acid biosynthesis pathway involving the up-regulation of the levels of cholic acid (CA), chenodeoxycholic acid (CDCA), taurocholic acid (TCA), glycocholic acid (GCA), taurochenodesoxycholic acid (TCDCA), and taurine.

    This study sought to investigate the relative safety and efficacy of bioabsorbable polymer (BP)-based biolimus-eluting stents (BES) versus durable-polymer (DP)-drug-eluting stents (DES) and bare-metal stents (BMS) by means of a network meta-analysis. Studies have suggested that BP-BES might reduce the risk of stent thrombosis (ST) and late adverse outcomes compared with first-generation DES. However, the relative safety and efficacy of BP-BES versus newer-generation DES coated with more biocompatible DP have not been investigated in depth. Randomized controlled trials comparing BP-BES versus currently U.S.-approved DES or BMS were searched through MEDLINE, EMBASE, and Cochrane databases. Information on study design, inclusion and exclusion criteria, sample characteristics, and clinical outcomes was extracted. Data from 89 trials including 85,490 patients were analyzed. At 1-year follow-up, BP-BES were associated with lower rates of cardiac death/myocardial infarction (MI), MI, and target vessel revascularization (TVR) than BMS and lower rates of TVR than fast-release zotarolimus-eluting stents. The BP-BES had similar rates of cardiac death/MI, MI, and TVR compared with other second-generation DP-DES but higher rates of 1-year ST than cobalt-chromium everolimus-eluting stents (CoCr-EES). The BP-BES were associated with improved late outcomes compared with BMS and paclitaxel-eluting stents, considering the latest follow-up data available, with nonsignificantly different outcomes compared with other DP-DES although higher rates of definite ST compared with CoCr-EES. In this large-scale network meta-analysis, BP-BES were associated with superior clinical outcomes compared with BMS and first-generation DES and similar rates of cardiac death/MI, MI, and TVR compared with second-generation DP-DES but higher rates of definite ST than CoCr-EES.

    Full Text Available The patients with chronic pain are increasingly reporting to the physicians for its management. Chronic pain are associated with head, neck and shoulder pain, spinal pain, pain in the joints and extremities, complex regional pain syndrome and phantom pain. The chronic pain is being managed worldwide. The different specialty of medicine is producing a lot of evidence through the published literature but the same is not being published in the field of chronic pain management. Though some evidence is being reported as to different aspects of pain management from different parts of the world but same is lacking from Indian subcontinent. This is in contrast to much done clinical work in this field as well. We present here the available evidence in relation to chronic pain management.

    The Bactrocera dorsalis species complex, currently comprising about 90 entities has received much attention. During the last decades, considerable effort has been devoted to delimiting the species of the complex. This information is of great importance for agriculture and world trade, since the complex harbours several pest species of major economic importance and other species that could evolve into global threats. Speciation in Diptera is usually accompanied by chromosomal rearrangements, particularly inversions that are assumed to reduce/eliminate gene flow. Other candidates currently receiving much attention regarding their possible involvement in speciation are reproductive symbionts, such as Wolbachia, Spiroplasma, Arsenophonus, Rickettsia and Cardinium. Such symbionts tend to spread quickly through natural populations and can cause a variety of phenotypes that promote pre-mating and/or post-mating isolation and, in addition, can affect the biology, physiology, ecology and evolution of their insect hosts in various ways. Considering all these aspects, we present: (a) a summary of the recently gained knowledge on the cytogenetics of five members of the Bactrocera dorsalis complex, namely Bactrocera dorsalis s.s., Bactrocera invadens, Bactrocera philippinensis, Bactrocera papayae and Bactrocera carambolae, supplemented by additional data from a Bactrocera dorsalis s.s. colony from China, as well as by a cytogenetic comparison between the dorsalis complex and the genetically close species, Bactrocera tryoni, and, (b) a reproductive symbiont screening of 18 different colonized populations of these five taxa. Our analysis did not reveal any chromosomal rearrangements that could differentiate among them. Moreover, screening for reproductive symbionts was negative for all colonies derived from different geographic origins and/or hosts. There are many different factors that can lead to speciation, and our data do not support chromosomal and/or symbiotic-based

    Currently there is an ongoing debate and limited evidence on the use of masks and respirators for the prevention of respiratory infections in health care workers (HCWs). This study aimed to examine available policies and guidelines around the use of masks and respirators in HCWs and to describe areas of consistency between guidelines, as well as gaps in the recommendations, with reference to the WHO and the CDC guidelines. Policies and guidelines related to mask and respirator use for the prevention of influenza, SARS and TB were examined. Guidelines from the World Health Organization (WHO), the Center for Disease Control and Prevention (CDC), three high-income countries and six low/middle-income countries were selected. Uniform recommendations are made by the WHO and the CDC in regards to protecting HCWs against seasonal influenza (a mask for low risk situations and a respirator for high risk situations) and TB (use of a respirator). However, for pandemic influenza and SARS, the WHO recommends mask use in low risk and respirators in high risk situations, whereas, the CDC recommends respirators in both low and high risk situations. Amongst the nine countries reviewed, there are variations in the recommendations for all three diseases. While, some countries align with the WHO recommendations, others align with those made by the CDC. The choice of respirator and the level of filtering ability vary amongst the guidelines and the different diseases. Lastly, none of the policies discuss reuse, extended use or the use of cloth masks. Currently, there are significant variations in the policies and recommendations around mask and respirator use for protection against influenza, SARS and TB. These differences may reflect the scarcity of level-one evidence available to inform policy development. The lack of any guidelines on the use of cloth masks, despite widespread use in many low and middle-income countries, remains a policy gap. Health organizations and countries should

    INTRODUCTION: A probabilistic decision support model such as the Integrated Medical Model (IMM) utilizes an immense amount of input data that necessitates a systematic, integrated approach for data collection, and management. As a result of this approach, IMM is able to forecasts medical events, resource utilization and crew health during space flight. METHODS: Inflight data is the most desirable input for the Integrated Medical Model. Non-attributable inflight data is collected from the Lifetime Surveillance for Astronaut Health study as well as the engineers, flight surgeons, and astronauts themselves. When inflight data is unavailable cohort studies, other models and Bayesian analyses are used, in addition to subject matters experts input on occasion. To determine the quality of evidence of a medical condition, the data source is categorized and assigned a level of evidence from 1-5; the highest level is one. The collected data reside and are managed in a relational SQL database with a web-based interface for data entry and review. The database is also capable of interfacing with outside applications which expands capabilities within the database itself. Via the public interface, customers can access a formatted Clinical Findings Form (CLiFF) that outlines the model input and evidence base for each medical condition. Changes to the database are tracked using a documented Configuration Management process. DISSCUSSION: This strategic approach provides a comprehensive data management plan for IMM. The IMM Database s structure and architecture has proven to support additional usages. As seen by the resources utilization across medical conditions analysis. In addition, the IMM Database s web-based interface provides a user-friendly format for customers to browse and download the clinical information for medical conditions. It is this type of functionality that will provide Exploratory Medicine Capabilities the evidence base for their medical condition list

    Full Text Available Global acknowledgement of ecological restoration, as an important tool to complement conservation efforts, requires an effort to increase the effectiveness of restoration interventions. Evidence-based practice is purported to promote effectiveness. A central tenet of this approach is decision making that is based on evidence, not intuition. Evidence can be generated experimentally and in practice but needs to be linked to baseline information collection, clear goals and monitoring of impact. In this paper, we report on a survey conducted to assess practitioners’ perceptions of the evidence generated in restoration practice in South Africa, as well as challenges encountered in building this evidence base. Contrary to a recent assessment of this evidence base which found weaknesses, respondents viewed it as adequate and cited few obstacles to its development. Obstacles cited were mostly associated with planning and resource availability. We suggest that the disparity between practitioners’ perceptions and observed weaknesses in the evidence base could be a challenge in advancing evidence-based restoration. We explore opportunities to overcome this disparity as well as the obstacles listed by practitioners. These opportunities involve a shift from practitioners as users of scientific knowledge and evidence, to practitioners involved in the co-production of evidence needed to increase the effectiveness of restoration interventions.

    Evidence-based policy (EBP), a concept modelled on the principles of evidence-based medicine (EBM), is widely used in different areas of policymaking. Systematic reviews (SRs) with meta-analyses gradually became the methods of choice for synthesizing research evidence about interventions and judgements about quality of evidence and strength of recommendations. Critics have argued that the relation between research evidence and service policies is weak, and that the notion of EBP rests on a misunderstanding of policy processes. Having explored EBM standards and knowledge requirements for health policy decision-making, we present an empirical point of departure for discussing the relationship between EBM and EBP. In a case study exploring the Norwegian Knowledge Centre for the Health Services (NOKC), an independent government unit, we first searched for information about the background and development of the NOKC to establish a research context. We then identified, selected and organized official NOKC publications as an empirical sample of typical top-of-the-line knowledge delivery adhering to EBM standards. Finally, we explored conclusions in this type of publication, specifically addressing their potential as policy decision tools. From a total sample of 151 SRs published by the NOKC in the period 2004-2013, a purposive subsample from 2012 (14 publications) advised major caution about their conclusions because of the quality or relevance of the underlying documentation. Although the case study did not include a systematic investigation of uptake and policy consequences, SRs were found to be inappropriate as universal tools for health policy decision-making. The case study demonstrates that EBM is not necessarily suited to knowledge provision for every kind of policy decision-making. Our analysis raises the question of whether the evidence-based movement, represented here by an independent government organization, undertakes too broad a range of commissions using

    Full Text Available The main focus of the present paper is to answer two different questions: From the perspective of Austrian education policy, which core areas of schooling are linked to the demand for equal opportunity? Can these reform efforts sustain the current state of research, and what are the consequences for schooling? The paper draws on an analysis by Hopmann, Geppert & Bauer (2010. Fifteen official self-presentations (political programmes of Austrian political parties were analysed for statements concerning the improvement of the education system. This resulted in about seventy different statements, which were aggregated into eight core areas.We conducted a systematic analysis of four of these core areas, dealing with the topics of equal opportunity: comprehensive school, all-day schooling, school autonomy and standardisation of students’ achievements. The aim was not to judge the legitimacy or the political content of the claims made. In line with evaluative discourse, we asked whether the combination of political demands and their associated expectations met the current state of research. In many policy programmes, it is assumed that comprehensive schooling, all-day schooling, education standards, standardised general certification for university attendance, school autonomy or language surveys go hand in hand with more equality of opportunity, justice andquality in education, but an analysis of the current state of research could not confirm this. The analysis showed that, with regard to education policy demands, statements having empirically little or nothing to do with each other are often linked.

    Full Text Available Threatened miscarriage is the commonest complication of early pregnancy and affects about 20% of pregnancies. It presents with vaginal bleeding with or without abdominal cramps. Increasing age of women, smoking, obesity or polycystic ovary syndrome (PCOS and a previous history of miscarriage are risk factors for threatened miscarriage. The pathophysiology has been associated with changes in levels of cytokines or maternal immune dysfunction. Clinical history and examination, maternal serum biochemistry and ultrasound findings are important to determine the treatment options and provide valuable information for the prognosis. Bed rest is the commonest advice, but there is little evidence of its value. Other options include progesterone, human chorionic gonadotropin (HCG and muscle relaxants. The complementary and alternative medicine (CAM therapies such as acupuncture and Chinese herbs have also been tried. There is some evidence from clinical studies indicating that CAM therapies may reduce the rate of miscarriage, but the quality of studies is poor. Thus, further double-blind, randomized-controlled trials are necessary to confirm its effectiveness, especially acupuncture and Chinese herbs.

    Venous Thromboembolism (VTE) is a cause of hospital mortality and managing its morbidity is associated with significant expenditure. Uptake of evidenced based guideline recommendations intended to prevent VTE in hospital settings is sub-optimal. This study was conducted to explore clinicians' attitudes and the clinical environment in which they work to understand their reluctance to adopt VTE prophylaxis guidelines. Between February and November 2009, 40 hospital employed doctors from 2 Australian metropolitan hospitals were interviewed in depth. Qualitative data were analysed according to thematic methodology. Analysis of interviews revealed that barriers to evidence based practice include i) the fragmented system of care delivery where multiple members of teams and multiple teams are responsible for each patient's care, and in the case of VTE, where everyone shares responsibility and no-one in particular is responsible; ii) the culture of practice where team practice is tailored to that of the team head, and where medicine is considered an 'art' in which guidelines should be adapted to each patient rather than applied universally. Interviewees recommend clear allocation of responsibility and reminders to counteract VTE risk assessment being overlooked. Senior clinicians are the key enablers for practice change. They will need to be convinced that guideline compliance adds value to their patient care. Then with the support of systems in the organisation designed to minimize the effects of care fragmentation, they will drive practice changes in their teams. We believe that evidence based practice is only possible with a coordinated program that addresses individual, cultural and organisational constraints.

    Full Text Available Objective To evaluate the therapeutic efficacy and side effects of various treatment for sleep disorders in order to provide the best therapeutic regimen for the evidence-based treatment of sleep disorders. Methods Sleep disorder, insomnia, restless legs syndrome or RLS, obstructive sleep apnea or OSA, narcolepsy, REM behaviour disorder or RBD, treatment or therapy were used as retrieval words. Cochrane Library, MEDLINE, ScienceDirect were used for retrieval, and manual searching was also used. Related clinical guidelines, systematic reviews, randomized controlled clinical trials, retrospective case analysis, case-observation studies and reviews were collected and evaluated by Jadad Scale. Results Forty related articles were selected as following: 6 clinical guidelines, 12 systematic reviews, 5 randomized controlled trials, 2 retrospective case analysis, 1 case-observation study and 14 reviews. Thirty-three were of high quality, while 7 were of low quality with score. According to the evaluation of therapeutic efficacy and side effects of various therapies, it is suggested as following: 1 insomnia is the most common in sleep disorders; the treatment methods of insomnia mainly include drug therapy and cognitive behavioral treatment (CBT; the two kinds of therapy have their own advantages and disadvantages, and the combination therapy of drugs and CBT is the best treatment plan. 2 The first-line treatment of primary RLS is dopamine agonists and anti-seizure drugs; however, the treatment of secondary RLS is mainly etiologic treatment. 3 The main treatments of OSAS are nasal continuous positive airway pressure (nCPAP, oral orthotics and surgery, and nCPAP is the first-line treatments. 4 The medication of narcolepsy is mainly modafinil, hydroxy butyric acid sodium and antidepressants, and the specific choosingshould accord to clinical classifications. 5 The main treatments of RBD include general treatments such as avoiding triggers, insuring the

    Taxonomic confusion exists within the genus Epinephelus due to the lack of morphological specializations and the overwhelming number of species reported in several studies. The homogenous nature of the morphology has created confusion in the Malaysian Marine fish species Epinephelus fuscoguttatus and Epinephelus hexagonatus. In this study, the partial DNA sequence of the 16S gene and mitochondrial nucleotide sequences of two gene regions, Cytochrome Oxidase Subunit I and III were used to investigate the phylogenetic relationship between them. In the phylogenetic trees, E. fuscoguttatus was monophyletic with E. hexagonatus species and morphology examination shows that no significant differences were found in the morphometric features between these two taxa. This suggests that E. fuscoguttatus is not distinguishable from E. hexagonatus species, and that E. fuscoguttatus have been identified to be E. hexagonatus species is likely attributed to differences in environment and ability to camouflage themselves under certain conditions. Interestingly, this finding was also supported by Principal Component Analysis on Attenuated Total Reflectance-Fourier-transform Infrared (ATR-FTIR) data analysis. Molecular, morphological and meristic characteristics were combined with ATR-FTIR analysis used in this study offer new perspectives in fish species identification. To our knowledge, this is the first report of an extensive genetic population study of E. fuscoguttatus in Malaysia and this understanding will play an important role in informing genetic stock-specific strategies for the management and conservation of this highly valued fish.

    2012-08-01

    Instrument development consistent with best practices is necessary for effective assessment and evaluation of learners and programs across the medical education continuum. The author explored the extent to which current factor analytic methods and other techniques for establishing validity are consistent with best practices. The author conducted electronic and hand searches of the English-language medical education literature published January 2006 through December 2010. To describe and assess current practices, she systematically abstracted reliability and validity evidence as well as factor analysis methods, data analysis, and reported evidence from instrument development articles reporting the application of exploratory factor analysis and principal component analysis. Sixty-two articles met eligibility criteria. They described 64 instruments and 95 factor analyses. Most studies provided at least one source of evidence based on test content. Almost all reported internal consistency, providing evidence based on internal structure. Evidence based on response process and relationships with other variables was reported less often, and evidence based on consequences of testing was not identified. Factor analysis findings suggest common method selection errors and critical omissions in reporting. Given the limited reliability and validity evidence provided for the reviewed instruments, educators should carefully consider the available supporting evidence before adopting and applying published instruments. Researchers should design for, test, and report additional evidence to strengthen the argument for reliability and validity of these measures for research and practice.

  13. A care pathway analysis of tuberculosis patients in benin: Highlights on direct costs and critical stages for an evidence-based decision-making.

    Directory of Open Access Journals (Sweden)

    Samia Laokri

    Full Text Available BACKGROUND: Free tuberculosis control fail to protect patients from substantial medical and non-medical expenditure, thus a greater degree of disaggregation of patient cost is needed to fully capture their context and inform policymaking. METHODS: A retrospective cross-sectional study was conducted on a convenience sample of six health districts of Southern Benin. From August 2008 to February 2009, we recruited all smear-positive pulmonary tuberculosis patients treated under the national strategy in the selected districts. Direct out-of-pocket costs associated with tuberculosis, time delays, and care-seeking pattern were collected from symptom onset to end of treatment. RESULTS: Population description and outcome data were reported for 245 patients of whom 153 completed their care pathway. For them, the median overall direct cost was USD 183 per patient. Payments to traditional healers, self-medication drugs, travel, and food expenditures contributed largely to this cost burden. Patient, provider, and treatment delays were also reported. Pre-diagnosis and intensive treatment stages were the most critical stages, with median expenditure of USD 43 per patient and accounting for 38% and 29% of the overall direct cost, respectively. However, financial barriers differed depending on whether the patient lived in urban or rural areas. CONCLUSIONS: This study delivers new evidence about bottlenecks encountered during the TB care pathway. Financial barriers to accessing the free-of-charge tuberculosis control strategy in Benin remain substantial for low-income households. Irregular time delays and hidden costs, often generated by multiple visits to various care providers, impair appropriate patient pathways. Particular attention should be paid to pre-diagnosis and intensive treatment. Cost assessment and combined targeted interventions embodied by a patient-centered approach on the specific critical stages would likely deliver better program outcomes.

  14. Teaching evidence based practice to undergraduate nursing students.

    Sin, Mo-Kyung; Bliquez, Rebecca

    Considering the heightened importance of evidence-based practice in healthcare settings, incorporating evidence-based practice into the nursing curriculum, especially in baccalaureate programs is essential because this is a first step to prepare students for their professional role as an RN, and the undergraduate nursing students are the ones who will spend the most time with patients at their bedside providing direct care. Teaching evidence-based practice at the undergraduate level, however, can be challenging. Creative and enjoyable teaching strategies are instrumental in order to promote students' engagement and learning about evidence-based practice.

    As an important component of judicial expertise, forensic science is broad and highly specialized. With development of network technology, increasement of information resources, and improvement of people's legal consciousness, forensic scientists encounter many new problems, and have been required to meet higher evidentiary standards in litigation. In view of this, evidence-based concept should be established in forensic medicine. We should find the most suitable method in forensic science field and other related area to solve specific problems in the evidence-based mode. Evidence-based practice can solve the problems in legal medical field, and it will play a great role in promoting the progress and development of forensic science. This article reviews the basic theory of evidence-based medicine and its effect, way, method, and evaluation in the forensic medicine in order to discuss the application value of forensic evidence-based medicine in computer communication networks.

    2014-12-01

    Full Text Available Evidence based medicine is the training of health care professionals to access, assess and apply the best scientific evidence to clinical practice. EBM is the conscientious, explicit and judicious use of current best evidence along with clinical expertise and patient values in making decisions about the case of individual patients. The current undergraduate curriculum of health profession is based on past knowledge accumulated for years. The scientific relevance of the mostly outdated information has never been questioned. The students passively absorb this available knowledge and apply it in their future professional life. There is no active learning on their part, by way of positive enquiry and critical analysis of the curriculum imposed on them. This has an undesirable impact on their competency as health professionals and the quality of the health care imparted by them. Hence there is need for emphasis on the teaching of EBM skills in undergraduate, postgraduate, and continuing medical education programs. Early introduction of EBM in the undergraduate medical curriculum, in the form of a short course, using various modes of instruction, enhances the competence of critical thinking and also influences change in attitude towards EBM positively in medical students. The EBM course is planned to introduce in the curriculum of medical undergraduates at the beginning of second phase when they enter clinical posting. Total number of student would be 100 per batch and the course duration will be of 1 year. Educational methods program incorporates multiple teaching methods like lectures, discussion sessions, demonstration, case based learning, timely feedback, real life exposure, role modeling and peer evaluation.

    Skin barrier restoration represents the mainstay of the treatment of atopic dermatitis and the use of moisturizers is recommended by several international guidelines. The aim of the study was to investigate through an evidence-based medicine analysis the effectiveness and safety of different moisturizing products available for a non-pharmacological treatment of atopic dermatitis. A total of 92 randomized controlled trials (RCTs) have been identified and analyzed. The results confirm the presence of a reasonable number of studies highlighting moisturizers safety and effectiveness in the treatment of atopic dermatitis by improving disease severity, increasing the time of relapse and reducing the time of flares. Moisturizers containing urea, glycerin or glycyrrhetinic acid seem to show the greater evidence of efficacy being supported by more clinical trials. Among the existing moisturizers, those containing a single agent generally work although the heterogeneity of RCTs does not allow reaching more definitive conclusions. Moisturizers made of a mixture of substances seem to be more effective thanks to the presence of different active substances that may exert a synergistic effect. A meta-analysis of 4 RCTs confirms the efficacy of a medical device containing glycyrrhetinic acid, hyaluronic acid, shea butter, telmesteine, and vitis vinifera in the treatment of atopic dermatitis.

  7. Evidence for 5S rDNA Horizontal Transfer in the toadfish Halobatrachus didactylus (Schneider, 1801) based on the analysis of three multigene families

    Science.gov (United States)

    2012-01-01

    Background The Batrachoididae family is a group of marine teleosts that includes several species with more complicated physiological characteristics, such as their excretory, reproductive, cardiovascular and respiratory systems. Previous studies of the 5S rDNA gene family carried out in four species from the Western Atlantic showed two types of this gene in two species but only one in the other two, under processes of concerted evolution and birth-and-death evolution with purifying selection. Here we present results of the 5S rDNA and another two gene families in Halobatrachus didactylus, an Eastern Atlantic species, and draw evolutionary inferences regarding the gene families. In addition we have also mapped the genes on the chromosomes by two-colour fluorescence in situ hybridization (FISH). Results Two types of 5S rDNA were observed, named type α and type β. Molecular analysis of the 5S rDNA indicates that H. didactylus does not share the non-transcribed spacer (NTS) sequences with four other species of the family; therefore, it must have evolved in isolation. Amplification with the type β specific primers amplified a specific band in 9 specimens of H. didactylus and two of Sparus aurata. Both types showed regulatory regions and a secondary structure which mark them as functional genes. However, the U2 snRNA gene and the ITS-1 sequence showed one electrophoretic band and with one type of sequence. The U2 snRNA sequence was the most variable of the three multigene families studied. Results from two-colour FISH showed no co-localization of the gene coding from three multigene families and provided the first map of the chromosomes of the species. Conclusions A highly significant finding was observed in the analysis of the 5S rDNA, since two such distant species as H. didactylus and Sparus aurata share a 5S rDNA type. This 5S rDNA type has been detected in other species belonging to the Batrachoidiformes and Perciformes orders, but not in the Pleuronectiformes

    Full Text Available In human medicine, the management of care to ensure safety for the service-user constitutes an important element of the patient ‘journey.’ The name given to this discipline is patient safety. It is founded upon those elements of good medical practice which help avoid or mitigate human error.  Investigations in the U.S. first highlighted the alarming extent of medical error: Brennan et al. (1991 concluded that in the state of New York, the overall rate of adverse events was approximately 4% for hospitalised patients, which equated to over 13,000 deaths a year. Doctors looked to other safety critical industries and aviation in particular (Reason 1995, to address this phenomenon: there is now a wealth of research on the impact of various safety initiatives on measurable rates of harm. The World Health Organisation’s ‘Safe Surgery Saves Lives’ initiative - a campaign that advocates the use of a surgical checklist to standardise aspects of peri-operative care - is one example of aviation methodology successfully employed in a clinical setting (van Klei et al. 2012. The critical importance of effective communication, leadership and situational awareness has also been discussed at length in the human patient safety literature.ObjectivesVeterinary patient safety is an analogous discipline and researchers have attempted to understand more about the topic of veterinary medical error. However, the evidence-base for veterinary patient safety is sparse.  This presentation aims to summarise the evidence to date and highlight the benefits in practice of an emerging subject. MethodA search of the terms veterinary patient safety on the PubMed database from 1990 to 2016 was performed.Findings15 articles were identified as contributing to the veterinary patient safety literature.OutcomeThe available literature has addressed a number of areas. The use of checklists in a clinical setting has been proven to reduce the incidence of specific undesirable

    Objective: To update the 2004 American Academy of Neurology/Child Neurology Society practice parameter on treatment of infantile spasms in children. Methods: MEDLINE and EMBASE were searched from 2002 to 2011 and searches of reference lists of retrieved articles were performed. Sixty-eight articles were selected for detailed review; 26 were included in the analysis. Recommendations were based on a 4-tiered classification scheme combining pre-2002 evidence and more recent evidence. Results: There is insufficient evidence to determine whether other forms of corticosteroids are as effective as adrenocorticotropic hormone (ACTH) for short-term treatment of infantile spasms. However, low-dose ACTH is probably as effective as high-dose ACTH. ACTH is more effective than vigabatrin (VGB) for short-term treatment of children with infantile spasms (excluding those with tuberous sclerosis complex). There is insufficient evidence to show that other agents and combination therapy are effective for short-term treatment of infantile spasms. Short lag time to treatment leads to better long-term developmental outcome. Successful short-term treatment of cryptogenic infantile spasms with ACTH or prednisolone leads to better long-term developmental outcome than treatment with VGB. Recommendations: Low-dose ACTH should be considered for treatment of infantile spasms. ACTH or VGB may be useful for short-term treatment of infantile spasms, with ACTH considered preferentially over VGB. Hormonal therapy (ACTH or prednisolone) may be considered for use in preference to VGB in infants with cryptogenic infantile spasms, to possibly improve developmental outcome. A shorter lag time to treatment of infantile spasms with either hormonal therapy or VGB possibly improves long-term developmental outcomes. PMID:22689735

    Our sense of rhythm relies on orchestrated activity of several cerebral and cerebellar structures. Although functional connectivity studies have advanced our understanding of rhythm perception, this phenomenon has not been sufficiently studied as a function of musical training and beyond the General Linear Model (GLM) approach. Here, we studied pulse clarity processing during naturalistic music listening using a data-driven approach (independent component analysis; ICA). Participants' (18 musicians and 18 controls) functional magnetic resonance imaging (fMRI) responses were acquired while listening to music. A targeted region of interest (ROI) related to pulse clarity processing was defined, comprising auditory, somatomotor, basal ganglia, and cerebellar areas. The ICA decomposition was performed under different model orders, i.e., under a varying number of assumed independent sources, to avoid relying on prior model order assumptions. The components best predicted by a measure of the pulse clarity of the music, extracted computationally from the musical stimulus, were identified. Their corresponding spatial maps uncovered a network of auditory (perception) and motor (action) areas in an excitatory-inhibitory relationship at lower model orders, while mainly constrained to the auditory areas at higher model orders. Results revealed (a) a strengthened functional integration of action-perception networks associated with pulse clarity perception hidden from GLM analyses, and (b) group differences between musicians and non-musicians in pulse clarity processing, suggesting lifelong musical training as an important factor that may influence beat processing.

    2012-03-01

    The objective was to review scientific evidence for efficacy and safety of pharmacotherapy in adults or children with an eating disorder (ED). We conducted a computer search for all randomized controlled trials (RCTs) published between 1960 and May 2010 for treatment of anorexia nervosa (AN), bulimia nervosa (BN) or binge-eating disorder (BED). For drugs for which no RCT was found, open trials or case reports were retrieved. Clinically relevant RCTs in the treatment of AN have used atypical antipsychotics, selective serotonin reuptake inhibitors (SSRIs), and zinc supplementation. Olanzapine demonstrated an adjunctive effect for in-patient treatment of underweight AN patients, and fluoxetine helped prevent relapse in weight-restored AN patients in 1/2 studies. For treatment of BN, controlled studies have used SSRIs, other antidepressants, and mood stabilizers. In 9/11 studies, pharmacotherapy yielded a statistically significant although moderate reduction in binge/purge frequency, and some additional benefits. For BED, RCTs have been conducted using SSRIs and one serotonin norepinephrine reuptake inhibitor (SNRI), mood stabilizers, and anti-obesity medications. In 11/12 studies, there was a statistically significant albeit limited effect of medication. Meta-analyses on efficacy of pharmacotherapy for BN and BED support moderate effect sizes for medication, but generally low recovery rates. Treatment resistance is an inherent feature of AN, where treatment should focus on renourishment plus psychotherapy. For BN and BED, combined treatment with pharmacotherapy and cognitive behaviour therapy has been more effective than either alone. Data on the long-term efficacy of pharmacotherapy for EDs are scarce. Short- and long-term pharmacotherapy of EDs still remains a challenge for the clinician.

    2017-11-01

    The current systematic review sought to compare available evidence-based clinical treatment guidelines for all specific eating disorders. Nine evidence-based clinical treatment guidelines for eating disorders were located through a systematic search. The international comparison demonstrated notable commonalities and differences among these current clinical guidelines. Evidence-based clinical guidelines represent an important step toward the dissemination and implementation of evidence-based treatments into clinical practice. Despite advances in clinical research on eating disorders, a growing body of literature demonstrates that individuals with eating disorders often do not receive an evidence-based treatment for their disorder. Regarding the dissemination and implementation of evidence-based treatments, current guidelines do endorse the main empirically validated treatment approaches with considerable agreement, but additional recommendations are largely inconsistent. An increased evidence base is critical in offering clinically useful and reliable guidance for the treatment of eating disorders. Because developing and updating clinical guidelines is time-consuming and complex, an international coordination of guideline development, for example, across the European Union, would be desirable.

  15. On evidence and evidence-based medicine: lessons from the philosophy of science.

    Science.gov (United States)

    Goldenberg, Maya J

    2006-06-01

    The evidence-based medicine (EBM) movement is touted as a new paradigm in medical education and practice, a description that carries with it an enthusiasm for science that has not been seen since logical positivism flourished (circa 1920-1950). At the same time, the term "evidence-based medicine" has a ring of obviousness to it, as few physicians, one suspects, would claim that they do not attempt to base their clinical decision-making on available evidence. However, the apparent obviousness of EBM can and should be challenged on the grounds of how 'evidence' has been problematised in the philosophy of science. EBM enthusiasm, it follows, ought to be tempered. The post-positivist, feminist, and phenomenological philosophies of science that are examined in this paper contest the seemingly unproblematic nature of evidence that underlies EBM by emphasizing different features of the social nature of science. The appeal to the authority of evidence that characterizes evidence-based practices does not increase objectivity but rather obscures the subjective elements that inescapably enter all forms of human inquiry. The seeming common sense of EBM only occurs because of its assumed removal from the social context of medical practice. In the current age where the institutional power of medicine is suspect, a model that represents biomedicine as politically disinterested or merely scientific should give pause.

    Planned organizational change processes can be used to address the many challenges facing human service organizations (HSOs) and improve organizational outcomes. There is massive literature on organizational change, ranging from popular management books to academic research on specific aspects of change. Regarding HSOs, there is a growing literature, including increasing attention to implementation science and evidence-based practices. However, research which offers generalizable, evidence-based guidelines for implementing change is not common. The purpose of the authors was to assess the evidence base in this organizational change literature to lay the groundwork for more systematic knowledge development in this important field.

    2010-01-01

    The American Music Therapy Association has recently put into action a plan called its Research Strategic Priority, with one of its central purposes to advance the music therapy field through research promoting Evidence-Based Practice of music therapy. The extant literature on music therapy practice, theory, and research conveys a range of very different perspectives on what may count as the "evidence" upon which practice is based. There is therefore a need to conceptualize evidence-based music therapy practice in a multifaceted, yet coherent and balanced way. The purpose of this paper is to illustrate a framework based upon four distinct epistemological perspectives on evidence-based music therapy practice that together represent an integral understanding.

    This article reviews the relation between evidence-based medicine and epidemiology and the recent evolution of the former. The meaning of evidence and the international efforts to collect, summarize, and disseminate findings from scientific research that are relevant for medical decision making are discussed. Evidence, current resources, and people's values, all play a role in making evidence-based medical decisions. This also has important implications for public health practice. However, decision making differs considerably between clinical care of individual patients and public health decision and policies that normally apply to populations. Although more closely related to epidemiology than clinical medicine, public health should also adopt a more systematic approach to evidence-based practice.

    It is unclear whether L1-VLP-based human papillomavirus (HPV) vaccines are efficacious in reducing the likelihood of anogenital pre-cancer in women with evidence of prior vaccine-type HPV exposure. This study aims to determine whether the combined results of the vaccine trials published to date provide evidence of efficacy compared with control (hepatitis A vaccine/placebo). A systematic review and meta-analysis was conducted. Randomized-controlled trials (RCTs) were identified from MEDLINE, Embase, Web of Science, PubMed, Cochrane Central Register of Controlled Trials and references of identified studies. The bivalent vaccine containing HPV-16 and 18 VLPs from GlaxoSmithKline Biologicals (Rixenstart, Belgium), the quadrivalent vaccine containing HPV-6, 11, 16, and 18 VLPs from Merck & Co., Inc., (Whitehouse Station, NJ USA), and the HPV-16 monovalent vaccine from Merck Research Laboratories (West Point, PA USA) were evaluated. Three RCT reports and two post-trial cohort studies were eligible, comprising data from 13,482 women who were included in the vaccine studies but had evidence of HPV infection at study entry. Data on efficacy was synthesized using the Mantel-Haenszel weighted fixed-effect approach, or where there was heterogeneity between studies, the DerSimonian and Laird weighted random-effect approach. The mean odds ratio (OR) and 95% confidence interval (CI) for the association between Cervarix, Gardasil and HPV-16 monovalent vaccine and HPV-associated cervical intraepithelial neoplasia grade 3 or worse was 0·90 (95% CI: 0·56, 1·44). For the association between Gardasil and HPV-associated vulval/vaginal intraepithelial neoplasia grades 2-3, the overall OR and 95% CI was 2.25 (95% CI: 0·78, 6.50). Sample size and follow-up were limited. There was no evidence that HPV vaccines are effective in preventing vaccine-type HPV associated pre-cancer in women with evidence of prior HPV exposure.

    Full Text Available Abstract Background Venous Thromboembolism (VTE is a cause of hospital mortality and managing its morbidity is associated with significant expenditure. Uptake of evidenced based guideline recommendations intended to prevent VTE in hospital settings is sub-optimal. This study was conducted to explore clinicians' attitudes and the clinical environment in which they work to understand their reluctance to adopt VTE prophylaxis guidelines. Methods Between February and November 2009, 40 hospital employed doctors from 2 Australian metropolitan hospitals were interviewed in depth. Qualitative data were analysed according to thematic methodology. Results Analysis of interviews revealed that barriers to evidence based practice include i the fragmented system of care delivery where multiple members of teams and multiple teams are responsible for each patient's care, and in the case of VTE, where everyone shares responsibility and no-one in particular is responsible; ii the culture of practice where team practice is tailored to that of the team head, and where medicine is considered an 'art' in which guidelines should be adapted to each patient rather than applied universally. Interviewees recommend clear allocation of responsibility and reminders to counteract VTE risk assessment being overlooked. Conclusions Senior clinicians are the key enablers for practice change. They will need to be convinced that guideline compliance adds value to their patient care. Then with the support of systems in the organisation designed to minimize the effects of care fragmentation, they will drive practice changes in their teams. We believe that evidence based practice is only possible with a coordinated program that addresses individual, cultural and organisational constraints.

  15. Sentiment Prediction Based on Dempster-Shafer Theory of Evidence

    2014-01-01

    Full Text Available Sentiment prediction techniques are often used to assign numerical scores to free-text format reviews written by people in online review websites. In order to exploit the fine-grained structural information of textual content, a review may be considered as a collection of sentences, each with its own sentiment orientation and score. In this manner, a score aggregation method is needed to combine sentence-level scores into an overall review rating. While recent work has concentrated on designing effective sentence-level prediction methods, there remains the problem of finding efficient algorithms for score aggregation. In this study, we investigate different aggregation methods, as well as the cases in which they perform poorly. According to the analysis of existing methods, we propose a new score aggregation method based on the Dempster-Shafer theory of evidence. In the proposed method, we first detect the polarity of reviews using a machine learning approach and then, consider sentence scores as evidence for the overall review rating. The results from two public social web datasets show the higher performance of our method in comparison with existing score aggregation methods and state-of-the-art machine learning approaches.

    Choe, Jae Gol

    2001-01-01

    EBM is 'the conscientious, explicit and judicious use of current best evidence in making decisions about the care of the individual patient. It means integrating individual clinical expertise with the best available external clinical evidence from systematic research.' EBM is the integration of clinical expertise, patient values, and the best evidence into the decision making process for patient care. The practice of EBM is usually triggered by patient encounters which generate questions about the effects of therapy, the utility of diagnostic tests, the prognosis of diseases, or the etiology of disorders. The best evidence is usually found in clinically relevant research that has been conducted using sound methodology. Evidence-based medicine requires new skills of the clinician, including efficient literature-searching, and the application of formal rules of evidence in evaluating the clinical literature. Evidence-based medicine converts the abstract exercise of reading and appraising the literature into the pragmatic process of using the literature to benefit individual patients while simultaneously expanding the clinician's knowledge base. This review will briefly discuss about concepts of evidence medicine and method of critical appraisal of literatures

  18. Towards Trustable Digital Evidence with PKIDEV: PKI Based Digital Evidence Verification Model

    Uzunay, Yusuf; Incebacak, Davut; Bicakci, Kemal

    How to Capture and Preserve Digital Evidence Securely? For the investigation and prosecution of criminal activities that involve computers, digital evidence collected in the crime scene has a vital importance. On one side, it is a very challenging task for forensics professionals to collect them without any loss or damage. On the other, there is the second problem of providing the integrity and authenticity in order to achieve legal acceptance in a court of law. By conceiving digital evidence simply as one instance of digital data, it is evident that modern cryptography offers elegant solutions for this second problem. However, to our knowledge, there is not any previous work proposing a systematic model having a holistic view to address all the related security problems in this particular case of digital evidence verification. In this paper, we present PKIDEV (Public Key Infrastructure based Digital Evidence Verification model) as an integrated solution to provide security for the process of capturing and preserving digital evidence. PKIDEV employs, inter alia, cryptographic techniques like digital signatures and secure time-stamping as well as latest technologies such as GPS and EDGE. In our study, we also identify the problems public-key cryptography brings when it is applied to the verification of digital evidence.

    The major difference between Iranian traditional medicine and allopathic medicine is in the application  of  evidence  and  documents.  In  this  study,  criteria  for  evidence-based  practice  in  Iranian traditional medicine and its rules of practice were studied. The experts' views were investigated through in- depth, semi-structured interviews and the results were categorized into four main categories including Designing clinical questions/clinical question-based search, critical appraisal, resource search criteria and clinical prescription appraisal. Although the application of evidence in Iranian traditional medicine follows Evidence Based Medicine (EBM) principles but it benefits from its own rules, regulations, and criteria that are compatible with EBM.

Although we have a fair understanding of the reasons for this progress, we don't have conclusive evidence for this. A new generation of road safety management approaches has entered road safety, starting when countries decided to guide themselves by setting quantitative targets (e.g. 50% less casualties in ten years' time. Setting realistic targets, designing strategies and action plans to achieve these targets and monitoring progress have resulted in more scientific research to support decision-making on these topics. Three subjects are key in this new approach of evidence-based and data-driven road safety management: ex-post and ex-ante evaluation of both individual interventions and intervention packages in road safety strategies, and transferability (external validity of the research results. In this article, we explore these subjects based on recent experiences in four jurisdictions (Western Australia, the Netherlands, Sweden and Switzerland. All four apply similar approaches and tools; differences are considered marginal. It is concluded that policy-making and political decisions were influenced to a great extent by the results of analysis and research. Nevertheless, to compensate for a relatively weak theoretical basis and to improve the power of this new approach, a number of issues will need further research. This includes ex-post and ex-ante evaluation, a better understanding of extrapolation of historical trends and the transferability of research results. This new approach cannot be realized without high-quality road safety data. Good data and knowledge are indispensable for this new and very promising approach.

    Full Text Available Abstract Background The reduction of health inequalities is a focus of many national and international health organisations. The need for pragmatic evidence-based approaches has led to the development of a number of evidence-based equity initiatives. This paper describes a new program that focuses upon evidence- based tools, which are useful for policy initiatives that reduce inequities. Methods This paper is based on a presentation that was given at the "Regional Consultation on Policy Tools: Equity in Population Health Reports," held in Toronto, Canada in June 2002. Results Five assessment tools were presented. 1. A database of systematic reviews on the effects of educational, legal, social, and health interventions to reduce unfair inequalities is being established through the Cochrane and Campbell Collaborations. 2 Decision aids and shared decision making can be facilitated in disadvantaged groups by 'health coaches' to help people become better decision makers, negotiators, and navigators of the health system; a pilot study in Chile has provided proof of this concept. 3. The CIET Cycle: Combining adapted cluster survey techniques with qualitative methods, CIET's population based applications support evidence-based decision making at local and national levels. The CIET map generates maps directly from survey or routine institutional data, to be used as evidence-based decisions aids. Complex data can be displayed attractively, providing an important tool for studying and comparing health indicators among and between different populations. 4. The Ottawa Equity Gauge is applying the Global Equity Gauge Alliance framework to an industrialised country setting. 5 The Needs-Based Health Assessment Toolkit, established to assemble information on which clinical and health policy decisions can be based, is being expanded to ensure a focus on distribution and average health indicators.

    In 2013, many public health functions transferred from the National Health Service to local government in England. From 2006 NICE had produced public health guidelines based on the principles of evidence-based medicine. This study explores how the guidelines were received in the new environment in local government and related issues raised relating to the use of evidence in local authoritites. In depth, interviews with 31 elected members and officers, including Directors of Public Health, from four very different local government organizations ('local authorities'). Participants reported that (i) there were tensions between evidence-based, and political decision-making; (ii) there were differences in views about what constituted 'good' evidence and (iii) that organizational life is an important mediator in the way evidence is used. Democratic political decision-making does not necessarily naturally align with decision-making based on evidence from the international scientific literature, and local knowledge and local evidence are very important in the ways that public health decisions are made. © The Author 2017.

    Although the effectiveness of interventions for prevention and treatment of mental health and behavioral problems in abused and neglected youth is demonstrated through the accumulation of evidence through rigorous and systematic research, it is uncertain whether use of research evidence (URE) by child-serving systems leaders increases the likelihood of evidence- based practice (EBP) implementation and sustainment. Information on URE was collected from 151 directors and senior administrators of child welfare, mental health and juvenile justice systems in 40 California and 11 Ohio counties participating in an RCT of the use of community development teams (CDTs) to scale up implementation of Treatment Foster Care Oregon over a 3 year period (2010-12). Separate multivariate models were used to assess independent effects of evidence acquisition (input), evaluation (process), application (output), and URE in general (SIEU Total) on two measures of EBP implementation, highest stage reached and proportion of activities completed at pre-implementation, implementation and sustainment phases. Stage of implementation and proportion of activities completed in the implementation and sustainment phases were independently associated with acquisition of evidence and URE in general. Participation in CDTs was significantly associated with URE in general and acquisition of research evidence in particular. Implementation of EBPs for treatment of abused and neglected youth does appear to be associated with use of research evidence, especially during the later phases.

    To identify patterns in information sharing between a series of Chinese evidence based medicine (EBM) journals and the Cochrane Database of Systematic Reviews, to determine key evidence dissemination areas for EBM and to provide a scientific basis for improving the dissemination of EBM research. Data were collected on citing and cited from the Chinese Journal of Evidence-Based Medicine (CJEBM), Journal of Evidence-Based Medicine (JEBMc), Chinese Journal of Evidence Based Pediatrics (CJEBP), and the Cochrane Database of Systematic Reviews (CDSR). Relationships between citations were visualized. High-frequency key words from these sources were identified, to build a word co-occurrence matrix and to map research subjects. CDSR contains a large collection of information of relevance to EBM and its contents are widely cited across many journals, suggesting a well-developed citation environment. The content and citation of the Chinese journals have been increasing in recent years. However, their citation environments are much less developed, and there is a wide variation in the breadth and strength of their knowledge communication, with the ranking from highest to lowest being CJEBM, JEBMc and CJEBP. The content of CDSR is almost exclusively Cochrane intervention reviews examining the effects of healthcare interventions, so it's contribution to EBM is mostly in disease control and treatment. On the other hand, the Chinese journals on evidence-based medicine and practice focused more on areas such as education and research, design and quality of clinical trials, evidence based policymaking, evidence based clinical practice, tumor treatment, and pediatrics. Knowledge and findings of EBM are widely communicated and disseminated. However, citation environments and range of knowledge communication differ greatly between the journals examined in this study. This finds that Chinese EBM has focused mainly on clinical medicine, Traditional Chinese Medicine, pediatrics, tumor

    Nowadays, evidence-based medicine (EBM) is essential to learn and to practice medicine. The aim of the current study was to investigate the baseline level of knowledge of French students regarding EBM. Between April and May2008, a questionnaire was sent by e-mail to 900students in their last year of medical study. On 327 answers, 297 (91%), 94 (29%) and 85 (26%) students declared they read, write and speak medical English. Ninety (28%) read an article of a French medical review once a month and 43 (13%) read an article of an international medical review once a month. Three hundred and eleven (95%) knew the bases of medical research on the Internet and 219 (67%) used them. Twenty-four (7%) had already participated in a editorial staff of a medical article, 7 (2%) had been co-authors. Two hundred and seventy-two (83%) had made an oral presentation during a medical staff and 3 (1%) during a congress. Finally, 237 (73%) understood the interest of the critical analysis of an article at the ECN and 70 (21%) thought they were prepared. The incapacity of learning EBM is one of the limits of the French medical training system. The introduction of the reading critical of an article at the ECN is the concrete beginning of an answer to this problem.

    2010-11-01

    With the considerable cost of disease-related malnutrition to individuals and to society (estimated to be >£13×109 for the UK, 2007 prices), there is a need for effective and evidence-based ways of preventing and treating this condition. The wide range of oral nutritional supplements that may be prescribed for the dietary management of malnutrition and other conditions account for only about 1% (about £99×106, 2007 data) of the prescribing budget in England. Systematic reviews and meta-analyses consistently suggest that ready-made, multi-nutrient liquids which may be prescribed can improve energy and nutritional intake, body weight and have a variety of clinical and functional benefits in a number of patient groups. Meta-analyses have repeatedly shown that oral nutritional supplements produce significant reductions in complications (e.g. infections) and mortality, and a recent meta-analysis shows a reduction in hospital admissions (OR 0·56 (95% CI 0·41, 0·77), six randomised controlled trials). Such benefits suggest that the appropriate use of oral nutritional supplements should form an integral part of the management of malnutrition, particularly as there is currently a lack of evidence for alternative oral nutrition strategies (e.g. food fortification and counselling). As with all therapies, compliance to oral nutritional supplements needs to be maximised and the use monitored. To make sure that those at risk of malnutrition are identified and treated appropriately, there is a need to embed national and local policies into routine clinical practice. In doing so, the economic burden of this costly condition can be curtailed. As recently suggested by the National Institute for Health and Clinical Excellence, substantial cost savings could be made if screening and treatment of malnourished patients was undertaken.

    Full Text Available The abbreviated article contains a brief overview of the contemporary state of evidence-based social work (EBSW and projections of its likely future. The forecast is based upon a review and analysis of the current trends and themes reflected in books, journal articles, dissertations, conferences, university programs, centers and resources available through the World Wide Web. The analysis suggests that the future of evidence-based practice (EBP in social work is likely to be characterized by further evolution, clarification, and explication of the EBP perspective; continued growth and popularity and a commensurate increase in the number of publications about EBP; modest increase in the number of practice-relevant research studies conducted by social workers; slight decrease in the gap between research-based knowledge and actual practice; and continued polarization within the profession about the relative value and utility of evidence-based social work.

    2018-03-01

    Evidence has the potential to be misleading if its value when expressing beliefs in hypotheses is not fully understood or presented. Although the knowledge base to understand uncertainties is growing, a challenge remains to prioritise research and to continuously assess the magnitude and consequences of misleading evidence in criminal cases. This study used a systematic content analysis to identify misleading evidence, drawing information from case transcripts of rulings argued unsafe by the Court of Appeal of England and Wales. In the 7-year study period, 218 applications were successful on appeal, containing 235 cases of misleading evidence. The majority (76%) of successful appeals were based upon the same materials available in the original trial, rather than the presentation of new relevant information. Witness (39%), forensic (32%), and character evidence (19%) were the most commonly observed evidence types, with the validity of witnesses (26%), probative value of forensic evidence (12%), and relevance of character evidence (10%) being the most prevalent combinations of identified issues. Additionally, the majority (66%) of misleading evidence types relate to their interpretation at activity level. The findings suggest that many of these misleading aspects could have been prevented by providing more transparency in the relationship between evidence and hypotheses. Generally, the results contribute to gaining a more complete picture of the role of misleading evidence in the criminal justice system. Copyright © 2017 The Authors. Published by Elsevier B.V.

    For more than a decade, nursing education has experienced several significant changes in response to challenges faced by healthcare organizations. Accrediting organizations have called for improved quality and safety in care, and the Institute of Medicine has identified evidence-based practice and quality improvement as 2 core competencies to include in the curricula for all healthcare professionals. However, the application of these competencies reaches far beyond the classroom setting. For nurses to possess the knowledge, skills, and attitudes to apply evidence-based practice and quality improvement to the real-world setting, academic-clinical institution partnerships are vital.

    Evidence-based nursing practice requires the use of effective search strategies to locate relevant resources to guide practice change. Continuing education and staff development professionals can assist nurses to conduct effective literature searches. This article provides suggestions for strategies to aid in identifying search terms. Strategies also are recommended for refining searches by using controlled vocabulary, truncation, Boolean operators, PICOT (Population/Patient Problem, Intervention, Comparison, Outcome, Time) searching, and search limits. Suggestions for methods of managing resources also are identified. Using these approaches will assist in more effective literature searches and may help evidence-based practice decisions.

    Little research exists linking interview-appropriate attire to improved employment outcomes for women. Thus, it appears that the professional clothing bank has not been investigated as evidence-based practice. To provide preliminary evidence for clothing banks, in this article the author synthesizes findings from existing research on the provision of a professional clothing bank as a means for offering interview-appropriate attire to poor women in job readiness programming. For context, job readiness programs are explored and a case study of one program operating a professional clothing bank is presented. Finally, preliminary considerations for planning and implementing clothing banks based on this literature review are given.

    2016-01-01

    This paper discusses an evidence-based approach to software requirements engineering. The approach is called evidence-based, since it uses publications on the specific problem as a surrogate for stakeholder interests, to formulate risks and testing experiences. This complements the idea that agile software development models are more relevant, in which requirements and solutions evolve through collaboration between self-organizing cross-functional teams. The strategy is exemplified and applied to the development of a Software Requirements list used to develop software systems for patient registries.

    2018-02-01

    A sizeable literature exists on the use of frequentist power analysis in the null-hypothesis significance testing (NHST) paradigm to facilitate the design of informative experiments. In contrast, there is almost no literature that discusses the design of experiments when Bayes factors (BFs) are used as a measure of evidence. Here we explore Bayes Factor Design Analysis (BFDA) as a useful tool to design studies for maximum efficiency and informativeness. We elaborate on three possible BF designs, (a) a fixed-n design, (b) an open-ended Sequential Bayes Factor (SBF) design, where researchers can test after each participant and can stop data collection whenever there is strong evidence for either [Formula: see text] or [Formula: see text], and (c) a modified SBF design that defines a maximal sample size where data collection is stopped regardless of the current state of evidence. We demonstrate how the properties of each design (i.e., expected strength of evidence, expected sample size, expected probability of misleading evidence, expected probability of weak evidence) can be evaluated using Monte Carlo simulations and equip researchers with the necessary information to compute their own Bayesian design analyses.

    Due to the removal of many pharmaceuticals from the prescription requirement, self-medication implies an increasing responsibility for pharmacists towards their patients. The application of evidence-based guidelines could be a responsible basis for consulting in pharmacies. Evidence-based guidelines represent the systematically accumulated and evaluated facts (the evidence) of desired and undesired effects of pharmaceuticals in the population. We wanted to find out which interest pharmaceutical professionals have in evidence-based guidelines and which are the exact requirements on their content, deducted from public pharmacies everyday demands. With this purpose, three surveys were conducted between March and August 2012, in which 365, 350, and 486 pharmaceutical professionals participated respectively. The results show that pharmacy staff is very interested in evidence based guidelines. Furthermore, they suggest that the pharmacy staff feel safe with the self-diagnosis of the customer, with the consideration of limits of self-medication, as well as with the selection of the--according to own assessment--appropriate active substance. For the selection of the correct active substance, the following criteria are named: self-security in the counselling, first-hand experiences as well as the wish of the customer. At the same time, it is striking that the most frequent critique the pharmacy staff gets from pharmacy customers is the lack of effectiveness of the selected medication. With that in mind, it is possible that not the appropriate medication was selected, and the chosen criteria as selection method should be replaced by an evidence-based decision. Secondly, the results show that in up to 52% of the cases, depending on the indications, the participating consultants felt less certain to uncertain with regards to possible interactions or contraindications. Also in this context, it is desirable to prepare the existing data in such a practical way, that the

    The need for an evidence base for human nutrition action is analysed in the context of human rights. Over the last 50 years the twin tracks of development, economical needs based and normative rights based, have come progressively closer in terms of goals and objectives, even if they do maintain different orientations and origins. The international human rights machinery is described, together with those parts that are of relevance to the right to food and nutrition. The role of the State in respecting, protecting and facilitating these rights is further described. The evidence base for the benefit of nutrition interventions during the fetal and infant period to the health and well-being of populations throughout life's course is briefly reviewed, and reasons why such a large body of evidence has not been acted upon are discussed. The power of nutrition is in prevention more than cure, and the prevention of nutritional deficiency is best suited to radical population-wide strategies rather than high-risk strategies targeted at individuals. The population-wide distribution of benefits of nutrition is in congruence with universality of human rights. In the UK much remains to be done to ensure that food and nutrition rights are realised, especially during the critical period of fetal and infant growth. What role the Nutrition Society might play in the realisation of these rights, including the creation of a robust evidence base for nutrition action, is further discussed.

    Strong evidence supports use of noninvasive ventilation (NIV) for patients with respiratory distress from chronic obstructive pulmonary disease and heart failure (strong evidence conditions [SECs]). Despite unclear benefits of NIV for other causes of acute respiratory failure, utilization for conditions with weaker evidence is increasing, despite evidence demonstrating higher mortality for patients who suffer NIV failure (progression from NIV to invasive mechanical ventilation [IMV])) compared with being treated initially with IMV. To determine the association of hospital variation in evidence-based utilization of NIV with patient outcomes. Using the California State Inpatient Database 2011, we identified adult patients who received NIV. Patients were considered to have an SEC for NIV if they had an acute exacerbation of chronic obstructive pulmonary disease or heart failure. We used multivariable hierarchical logistic regression to determine the association between hospital rates of NIV use for SECs and patient risk of NIV failure (need for IMV after NIV). Among 22,706 hospitalizations with NIV as the initial ventilatory strategy, 6,820 (30.0%) had SECs. Patients with SECs had lower risk of NIV failure than patients with weak evidence conditions (8.1 vs. 18.2%, P benefited from admission to hospitals that used NIV more often for patients with SECs (Quartile 4 vs. Quartile 1 adjusted odds ratio for NIV failure = 0.68; 95% CI = 0.52-0.88). Most patients who received NIV did not have conditions with strong supporting evidence for its use with wide institutional variation in patient selection for NIV. Surprisingly, we found that all patients, even those without an SEC, benefited from admission to hospitals with greater evidence-based utilization of NIV, suggesting a "hospital effect" that is synergistic with patient selection.

    Full Text Available Background. Evidence-based medicine employs systematic searching, evaluation and use of current research findings as the basis for clinical decision-making. However, there are some problems and uncertainties hindering introduction and spreading of the use of the method in clinical practice. Physicians often have no time for literature searching and for use of the method in practice. For certain questions in clinical practice there are no answers in medical literature. Most of the evidences in medical literature are only available in English. Introduction of the method is hampered also by the fact that clinical decision-making is complex and does not allow procedures prescribed in advance. Rigidity and universality of decisions resulting from the evidence may appear impersonal and may affect the relationship between the physician and the patient. Trends towards evidence based medicine are followed also by big multinational pharmaceutical corporations. They carry out large and expensive clinical trials using the results for promotional purposes. In this way, they get the competitive advantage and influence the objectivity of physicians’ clinical decision-making.Conclusions. With introduction of evidence based medicine into clinical practice physicians acquire new information and use a new form of continuing education by following new developments in their field. This way, new findings from medical literature get into clinical practice faster and more efficiently. In addition, physicians get more professional satisfaction and quality in clinical practice is higher.

    Full Text Available Evidence based medicine (EBM is the conscientious, explicit and judicious use of current best evidence in making decisions about the care of individual patients. It is estimated that only 15% of medical interventions is evidence-based. Increasing demand, new technological developments, malpractice legislations, a very speed increase in knowledge and knowledge sources push the physicians forward for EBM, but at the same time increase load of physicians by giving them the responsibility to improve their skills. Clinical maneuvers are needed more, as the number of clinical trials and observational studies increase. However, many of the physicians, who are in front row of patient care do not use this increasing evidence. There are several examples related to different training methods in order to improve skills of physicians for evidence based practice. There are many training methods to improve EBM skills and these trainings might be given during medical school, during residency or as continuous trainings to the actual practitioners in the field. It is important to discuss these different training methods in our country as well and encourage dissemination of feasible and effective methods. [TAF Prev Med Bull 2010; 9(3.000: 245-254

    The purpose of this paper is to analyze the implementation of an organizational change initiative--Studer Group®'s Evidence-Based Leadership (EBL)--in two large, US health systems by comparing and contrasting the factors associated with successful implementation and sustainability of the EBL initiative. This comparative case study assesses the responses to two pairs of open-ended questions during in-depth qualitative interviews of leaders and managers at both health systems. Qualitative content analysis was employed to identify major themes. Three themes associated with success and sustainability of EBL emerged at both health systems: leadership; culture; and organizational processes. The theme most frequently identified for both success and sustainability of EBL was culture. In contrast, there was a significant decline in salience of the leadership theme as attention shifts from success in implementation of EBL to sustaining EBL long term. Within the culture theme, accountability, and buy-in were most often cited by interviewees as success factors, while sense of accountability, buy-in, and communication were the most reported factors for sustainability. Cultural factors, such as accountability, staff support, and communication are driving forces of success and sustainability of EBL across both health systems. Leadership, a critical factor in several stages of implementation, appears to be less salient as among factors identified as important to longer term sustainability of EBL.

    The actively developing approach in modern medicine is the approach focused on principles of evidence-based medicine. The assessment of quality and reliability of studies is needed. However, in some cases studies corresponding to the first level of evidence may contain errors in randomized control trials (RCTs). Solution of the problem is the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system. Studies both in the fields of medicine and information retrieval are conducted for developing search engines for the MEDLINE database [1]; combined techniques for summarization and information retrieval targeted to solving problems of finding the best medication based on the levels of evidence are being developed [2]. Based on the relevance and demand for studies both in the field of medicine and information retrieval, it was decided to start the development of a search engine for the MEDLINE database search on the basis of the Saint-Petersburg State University with the support of Pavlov First Saint-Petersburg State Medical University and Tashkent Institute of Postgraduate Medical Education. Novelty and value of the proposed system are characterized by the use of ranking method of relevant abstracts. It is suggested that the system will be able to perform ranking based on studies level of evidence and to apply GRADE criteria for system evaluation. The assigned task falls within the domain of information retrieval and machine learning. Based on the results of implementation from previous work [3], in which the main goal was to cluster abstracts from MEDLINE database by subtypes of medical interventions, a set of algorithms for clustering in this study was selected: K-means, K-means ++, EM from the sklearn (http://scikit-learn.org) and WEKA (http://www.cs.waikato.ac.nz/~ml/weka/) libraries, together with the methods of Latent Semantic Analysis (LSA) [4] choosing the first 210 facts and the model "bag of words" [5] to represent clustered documents

    The purpose of this paper is to develop some thoughts on philosophical issues surrounding evidence-based medicine (EBM), especially related to its epistemological dimensions. After considering the scope of several philosophical concepts that are relevant to the discussion, and drawing some distinctions among different aspects of EBM, we evaluate the status of EBM and suggest that EBM is mainly a meta-methodology. Then, we outline an evaluation of the thesis that EBM is a 'new paradigm' in the practice of medicine. We argue that EBM does not seem to have arisen in the way Kuhn imagined paradigms to arise but as a conscious, deliberate proposal, more as programme than as a reality. Furthermore, there is something paradoxical about appealing to evidence or to the best evidence as a way of promoting a new paradigm. For the proposal seems to assume that there is something that by its own virtue is the best evidence for a given time. But this idea would have been rejected by Kuhn. If EBM involves a genuine new alternative in the field of medicine and shows a way in which the discipline will endure henceforth, this indicates that it is not what Kuhn once called a 'paradigm' and even, paradoxically, it is good evidence that scientific paradigms do not exist, at least in medicine. © 2015 John Wiley & Sons, Ltd.

  3. Analysis of indirect evidence in hit-and-run cases

    Full Text Available For personnel handling cases in public security bodies, evaluation of evidence is key to discover the fact and then to settle disputes. The process of evaluation shall be confirmed to rules of logic. Rules of logic are a set of judgment rules for people to reflect, induce, and deduce the development of law worldwide. Thus, evaluation of evidence shall be built on objective and rational logic deduction. Rules of logic applied in the investigation and judgment of evidence can help in finding a direct or indirect link between the evidence and the facts of an accident, thereby providing support and assistance for accident identification. It is particularly necessary to apply rules of logic to evaluate the indirect evidence chain in the investigation of hit-and-run traffic accident cases. This article demonstrates the specific application of such rules in the investigation of a serious hit-and-run traffic accident case. In the investigation process through the comprehensive analysis of and logical thinking around all indirect evidence, such as site inspection data, video monitoring data, witness testimony, and expert conclusions, and the combining of this with the direct evidence of the parties' statements, a complete chain of evidence for identifying a suspect's vehicle and the accident facts can be formed. The effective application of rules of logic in the evaluation of the indirect evidence chain in hit-and-run traffic accident cases provides more clues and narrows the scope of an investigation, improving its efficiency and accuracy, thereby helping to identify the facts of an accident.

    Over the past years concerns are rising about the use of Evidence-Based Medicine (EBM) in health care. The calls for an increase in the practice of EBM, seem to be obstructed by many barriers preventing the implementation of evidence-based thinking and acting in general practice. This study aims to explore the barriers of Flemish GPs (General Practitioners) to the implementation of EBM in routine clinical work and to identify possible strategies for integrating EBM in daily work. We used a qualitative research strategy to gather and analyse data. We organised focus groups between September 2002 and April 2003. The focus group data were analysed using a combined strategy of 'between-case' analysis and 'grounded theory approach'. Thirty-one general practitioners participated in four focus groups. Purposeful sampling was used to recruit participants. A basic classification model documents the influencing factors and actors on a micro-, meso- as well as macro-level. Patients, colleagues, competences, logistics and time were identified on the micro-level (the GPs' individual practice), commercial and consumer organisations on the meso-level (institutions, organisations) and health care policy, media and specific characteristics of evidence on the macro-level (policy level and international scientific community). Existing barriers and possible strategies to overcome these barriers were described. In order to implement EBM in routine general practice, an integrated approach on different levels needs to be developed.

    Sensor data fusion plays an important role in fault diagnosis. Dempster-Shafer (D-R) evidence theory is widely used in fault diagnosis, since it is efficient to combine evidence from different sensors. However, under the situation where the evidence highly conflicts, it may obtain a counterintuitive result. To address the issue, a new method is proposed in this paper. Not only the statistic sensor reliability, but also the dynamic sensor reliability are taken into consideration. The evidence distance function and the belief entropy are combined to obtain the dynamic reliability of each sensor report. A weighted averaging method is adopted to modify the conflict evidence by assigning different weights to evidence according to sensor reliability. The proposed method has better performance in conflict management and fault diagnosis due to the fact that the information volume of each sensor report is taken into consideration. An application in fault diagnosis based on sensor fusion is illustrated to show the efficiency of the proposed method. The results show that the proposed method improves the accuracy of fault diagnosis from 81.19% to 89.48% compared to the existing methods.

Methodological tools of Evidence-Based Medicine (EBM) were developed within the EBM Course in the Medical School of Torino, Italy, as problem solving and patient information tools (5th year students work in small groups under the supervision of statisticians, epidemiologists and experts of internal medicine--nephrology in this case). Methodological and ethical problems were identified: in the pre-dialysis field, evidence from randomized clinical trials (RCT) is scant; how to use evidence gathered in dialysis? How to deal with implementation? How with the mass media? Do we need to discuss the drug choice with the patients? How to deal with rare and severe side effects?). The "evidence" was searched for on Medline/Embase, by using key-words and free terms. About 680 papers were retrieved and screened. Forms available on the Internet were retrieved and a general scheme was drawn: it included 5 areas: title, aim and targets (patients and family physicians); search strategies and updating; pros and cons of therapy; alternative options; open questions. EBM may offer valuable tools for systematically approaching patient information; the inclusion of this kind of exercise in the Medical School EBM courses may help enhance the awareness of future physicians of the correct communication with patients.

    It was recognized early on that an Evidence-Based Medicine (EBM) approach could be applied to Public Health (PH), including the area of Occupational Health (OH). The aim of Evidence-Based Occupational Health (EBOH) is to ensure safety, health, and well-being in the workplace. Currently, high-quality research is necessary in order to provide arguments and scientific evidence upon which effective, efficient, and sustainable preventive measures and policies are to be developed in the workplace in Western countries. Occupational physicians need to integrate available scientific evidence and existing recommendations with a framework of national employment laws and regulations. This paper addresses the state of the art of scientific evidence available in the field (i.e., efficacy of interventions, usefulness of education and training of workers, and need of a multidisciplinary strategy integrated within the national PH programs) and the main critical issues for their implementation. Promoting good health is a fundamental part of the smart, inclusive growth objectives of Europe 2020 - Europe's growth strategy: keeping people healthy and active for longer has a positive impact on productivity and competitiveness. It appears clear that health quality and safety in the workplace play a key role for smart, sustainable, and inclusive growth in Western countries.

    There are several treatment proposals for the obstetric patient with pre-eclampsia, but there is limited evidence on the adequacy of standard treatment. International healthcare organisations recommend that hospitals or anaesthesia departments have written guidelines, protocols or recommendations for dealing with common or severe situations. We propose evidence-based recommendations for the treatment of pre-eclampsia. A literature review was performed using several sources, bibliography databases, recommendations made by specialist societies, and reviews. Four anaesthesiologists reviewed the references selected, in order to design clinical questions (these were obtained from recent pre-eclampsia review articles). Consensus of at least 3 out of 4 experts was required. The Oxford criteria for evidence were chosen to classify the scientific articles, and the Jadad score was applied to the final articles selected. A total of 50 clinical questions were designed and answered. These were classified into: general questions, influence of the type of delivery, pre-anaesthesia evaluation, peripartum treatment (including analgesia and anaesthesia), eclampsia, post-delivery period, and intensive care and transport. Most of the responses showed low scientific evidence. Evidence-based recommendations for severe pre-eclampsia treatment were provided with special emphasis on the anaesthesiologist point of view.

    2007-03-01

    With the dramatic increase in the amount of scientific information available about oral health, an evidence-based approach to oral health care and the practice of dentistry is necessary. There is a need to summarize, critique, and disseminate scientific evidence and to translate the evidence into a practical format that is used easily by dentists. The evidence-based clinical recommendations in this report were developed by an expert panel established by the American Dental Association Council on Scientific Affairs that evaluated the collective body of scientific evidence on the effectiveness of professionally applied topical fluoride for caries prevention. The recommendations are intended to assist dentists in clinical decision making. MEDLINE and the Cochrane Library were searched for systematic reviews and clinical studies of professionally applied topical fluoride-including gel, foam, and varnish-through October 2005. Panelists were selected on the basis of their expertise in the relevant subject matter. The recommendations are stratified by age groups and caries risk and indicate that periodic fluoride treatments should be considered for both children and adults who are at moderate or high risk of developing caries. Included in the clinical recommendations is a summary table that can be used as a chairside resource. The dentist, knowing the patient's health history and vulnerability to oral disease, is in the best position to make treatment decisions in the interest of each patient. These clinical recommendations must be balanced with the practitioner's professional expertise and the individual patient's preferences.

  20. Mass lesions in chronic pancreatitis: benign or malignant? An "evidence-based practice" approach.

    2012-02-01

    The diagnosis of a pancreatic mass lesion in the presence of chronic pancreatitis can be extremely challenging. At the same time, a high level of certainty about the diagnosis is necessary for appropriate management planning. The aim of this study was to establish current best evidence about which imaging methods reliably differentiate a benign from a malignant lesion, and show how that evidence is best applied. A diagnostic algorithm based on Bayesian analysis is proposed.

  1. An Evidence Base for Human Spaceflight Risks in Wikipedia

    NASA's Human Research Program (HRP) is focused on understanding and mitigating thirty two risks to crew health and performance in exploration missions beyond low Earth orbit. The HRP has developed an evidence report for each of the risks. Most evidence reports are a brief review article describing the evidence related to a specified risk, written at a level appropriate for the scientifically educated, non-specialist reader. Each evidence report captured the current state of knowledge from both research and operations. Two limitations of the evidence reports have become apparent: 1) they are updated infrequently and 2) they do not take full advantage of the expertise available in other space agencies and in related fields of terrestrial research. Therefore, the HRP is experimenting with the use of Wikipedia articles as a repository for evidence. Wikipedia's accessibility to the international space flight community and researchers in related terrestrial fields creates the opportunity to generate a more timely and comprehensive evidence base. Initial Wikipedia articles were populated for seven risks using a subset of the information in the HRP-approved evidence reports: Fatigue and Sleep Loss, Treating An Ill or Injured Crew Member, Radiation Carcinogenesis, Visual Impairment and Intracranial Pressure, Renal Stone Formation, Team Cohesion, and Intervertebral Disc Damage. Since the initial articles were created, there have been additions to these Wikipedia articles, including content from sources outside the HRP, and editorial changes to the pages. We will report on the nature of the contributions made after the initial articles were created, the comprehensiveness of the resulting Wikipedia articles, and the effort required to maintain quality control of the content. The Wikipedia approach will also be compared to wiki efforts that exert more traditional editorial control of content prior to posting.

    Playing a musical instrument that loads the masticatory system has frequently been linked to temporomandibular disorders (TMDs). Previous literature reviews on this topic do not conform to the current standards of evidence-based medicine. To investigate the effects of playing a musical instrument (i.e. violin/viola and wind instruments) or singing on the presence of TMDs, based on evidence derived from observational studies. Databases of Medline, Web of Science and Google Scholar were searched using MeSH and other relevant terms. For each study, a quality assessment was undertaken using a modified version of the Newcastle-Ottawa Scale (NOS). Fifteen relevant papers were identified for inclusion in this review. Of the seven possible points that could be scored with the NOS, the majority of these studies scored under half. Based on the available evidence, the purported relationship between the playing of specific musical instruments and TMDs was not as evident as reported in previous literature reviews. There is limited evidence to conclude that playing a wind instrument is a hazard to the temporomandibular system. Furthermore, there is no available evidence to suggest that vocalists experience more TMDs than controls. The studies that investigated the presence of TMDs among violists and violinists yielded ambiguous outcomes; some studies reported no association between the playing of these instruments and the presence of signs and symptoms of TMDs, whereas in studies where a clinical examination was performed (though of lower methodological quality), an association was found. © The Author 2017.

    Moch, Susan D; Quinn-Lee, Lisa; Gallegos, Cara; Sortedahl, Charlotte K

    : An innovative way to facilitate evidence-based practice (EBP) learning and to get evidence into practice is through academic-clinical agency projects involving faculty, undergraduate students, and agency staff. The central role of the faculty is key to successful academic-clinical agency partnerships. Faculty navigate the often difficult process of focusing students and engaging busy staff through initiating, maintaining, and evaluating projects. Students learn valuable EBP skills, staff become engaged in EBP, and the projects are rated highly by agency administrators.

  5. Improving the evidence for ecosystem-based adaptation

    Reid, Hannah

    2011-11-15

    Ecosystem-based approaches to adaptation (EBA) integrate the use of biodiversity and ecosystem services into an overall strategy for helping people adapt to climate change. The body of scientific evidence that indicates how effective they are is in some cases lacking but in other cases is dispersed across a range of related fields, such as natural resource management, disaster risk reduction and agroecology, from which it needs to be synthesised. Without presenting and strengthening this evidence in a consolidated way, EBA cannot secure the policy traction at local, national and international levels that it merits.

    2016-01-01

    Recommendations for the evaluation of quality improvement interventions have been made in order to improve the evidence base of whether, to what extent, and why quality improvement interventions affect chosen outcomes. The purpose of this article is to articulate why these recommendations are appropriate to improve the rigor of quality improvement intervention evaluation as a research endeavor, but inappropriate for the purposes of everyday quality improvement practice. To support our claim, we describe the differences between quality improvement interventions that occur for the purpose of practice as compared to research. We then carefully consider how feasibility, ethics, and the aims of evaluation each impact how quality improvement interventions that occur in practice, as opposed to research, can or should be evaluated. Recommendations that fit the evaluative goals of practice-based quality improvement interventions are needed to support fair appraisal of the distinct evidence they produce. We describe a current debate on the nature of evidence to assist in reenvisioning how quality improvement evidence generated from practice might complement that generated from research, and contribute in a value-added way to the knowledge base.

  7. The personalised medicine: a paradigm of evidence-based medicine

    Full Text Available The practice of "evidence-based medicine" aims at the conscientious, explicit and judicious use of the current best evidence in making decisions about the individualised patient care. The clinical genetics evolved from translational genetics research and contributes to the clinical care of patients and families through evidence-based health care in managing inherited disorders through accurate diagnosis, molecular pathology and assessing phenotypic correlations. Translational genetics and genomics research has led to the development of powerful tools for clinical diagnosis, assessing individual's genomic profile for disease prediction/prevention, high-throughput genome-wide screening for predisposition and/or protection to complex medical conditions, and discovery and development of new drugs and vaccines. Gene mapping and deciphering pathogenic mutations have helped in unravelling the basic biological mechanisms leading to new drug discovery and development. Targeted pharmacotherapy is now possible for managing the highly penetrant multi-system dominantly inherited conditions. Notable examples include rapamycin (sirolimus in suppressing the mTOR pathway associated hamartomas in dominantly inherited cancer family syndromes and angiotensin converting enzyme receptor blockers (ACE-RB in preventing aortic dilatation in Marfan syndrome and related familial arteriopathies. The translational genomic research is the essential prerequisite for developing sound evidence-based diagnostic, therapeutic and prognostic clinical protocols for the practice of personalised clinical medicine.

    This paper reports on the development of a tool by the Arizona Health Sciences Library (AHSL) for searching clinical evidence that can be customized for different user groups. The AHSL provides services to the University of Arizona's (UA's) health sciences programs and to the University Medical Center. Librarians at AHSL collaborated with UA College of Medicine faculty to create an innovative search engine, Evidence-based Medicine (EBM) Search, that provides users with a simple search interface to EBM resources and presents results organized according to an evidence pyramid. EBM Search was developed with a web-based configuration component that allows the tool to be customized for different specialties. Informal and anecdotal feedback from physicians indicates that EBM Search is a useful tool with potential in teaching evidence-based decision making. While formal evaluation is still being planned, a tool such as EBM Search, which can be configured for specific user populations, may help lower barriers to information resources in an academic health sciences center.

  9. When is enough evidence enough? - Using systematic decision analysis and value-of-information analysis to determine the need for further evidence.

    Decision analysis (DA) and value-of-information (VOI) analysis provide a systematic, quantitative methodological framework that explicitly considers the uncertainty surrounding the currently available evidence to guide healthcare decisions. In medical decision making under uncertainty, there are two fundamental questions: 1) What decision should be made now given the best available evidence (and its uncertainty)?; 2) Subsequent to the current decision and given the magnitude of the remaining uncertainty, should we gather further evidence (i.e., perform additional studies), and if yes, which studies should be undertaken (e.g., efficacy, side effects, quality of life, costs), and what sample sizes are needed? Using the currently best available evidence, VoI analysis focuses on the likelihood of making a wrong decision if the new intervention is adopted. The value of performing further studies and gathering additional evidence is based on the extent to which the additional information will reduce this uncertainty. A quantitative framework allows for the valuation of the additional information that is generated by further research, and considers the decision maker's objectives and resource constraints. Claxton et al. summarise: "Value of information analysis can be used to inform a range of policy questions including whether a new technology should be approved based on existing evidence, whether it should be approved but additional research conducted or whether approval should be withheld until the additional evidence becomes available." [Claxton K. Value of information entry in Encyclopaedia of Health Economics, Elsevier, forthcoming 2014.] The purpose of this tutorial is to introduce the framework of systematic VoI analysis to guide further research. In our tutorial article, we explain the theoretical foundations and practical methods of decision analysis and value-of-information analysis. To illustrate, we use a simple case example of a foot ulcer (e.g., with

    Obsessive–compulsive disorder (OCD) is a neuropsychiatric illness that often develops in childhood, affects 1%–2% of the population, and causes significant impairment across the lifespan. The first step in identifying and treating OCD is a thorough evidence-based assessment. This paper reviews the administration pragmatics, psychometric properties, and limitations of commonly used assessment measures for adults and youths with OCD. This includes diagnostic interviews, clinician-administered symptom severity scales, self-report measures, and parent/child measures. Additionally, adjunctive measures that assess important related factors (ie, impairment, family accommodation, and insight) are also discussed. This paper concludes with recommendations for an evidence-based assessment based on individualized assessment goals that include generating an OCD diagnosis, determining symptom severity, and monitoring treatment progress.

    Full Text Available Consumers and patients want to be included in decisions regarding their own health and have an ethically justified claim on informed decisions. Therefore, sound information is required, but health information is often misleading and based on different interests. The risks of disease and the benefits of medical interventions tend to be overestimated, whereas harm is often underestimated. Evidence-based health information has to fulfil certain criteria, for instance, it should be evidence-based, independent, complete, true as well as understandable. The aim of a medical intervention has to be explained. The different therapeutic options including the option not to intervene have to be delineated. The probabilities for success, lack of success and unwanted side effects have to be communicated in a numerical and understandable manner. Patients have the right to reject medical interventions without any sanctions.

    Full Text Available Abstract Background Chiropractors must continue to learn, develop themselves professionally throughout their careers, and become self-directed and lifelong learners. Using an evidence-based approach increases the probability of optimal patient outcomes. But most chiropractors lack knowledge and interest in evidence-based approaches. The purpose of this study was to develop and measure the effectiveness of evidence-based training for chiropractic practitioners in a continuing education setting. Methods We developed and evaluated a continuing education workshop on evidence-based principles and methods for chiropractic practitioners. Forty-seven chiropractors participated in the training and testing. The course consisted of 12.5 hours of training in which practitioners learned to develop focused questions, search electronic data bases, critically review articles and apply information from the literature to specific clinical questions. Following the workshop, we assessed the program performance through the use of knowledge testing and anonymous presentation quality surveys. Results Eighty-five percent of the participants completed all of the test, survey and data collection items. Pretest knowledge scores (15-item test were low (47%. Post intervention scores (15-item test improved with an effect size of 2.0. A 59-item knowledge posttest yielded very good results (mean score 88%. The quality of presentation was rated very good, and most participants (90% would "definitely recommend" or "recommend" the workshop to a colleague. Conclusion The results of the study suggest that the continuing education course was effective in enhancing knowledge in the evidence-based approach and that the presentation was well accepted.

    To describe evidence-based practice among head nurses and to explore whether number of years of duty is associated with such activities. Further to evaluate the effects of education on evidence-based practice and perceived support from immediate superiors. Registered nurses in Sweden are required by law to perform care based on research findings and best experiences. In order to achieve this, evidence-based practice (EBP) is of key importance. All 168 head nurses at two hospitals were asked to participate. Ninety-nine (59%) completed the survey. Data were collected using a study-specific web-based questionnaire. The majority reported a positive attitude towards EBP, but also a lack of time for EBP activities. A greater number of years as a head nurse was positively correlated with research utilization. Education in research methods and perceived support from immediate superiors were statistically and significantly associated with increased EBP activities. The present study highlights the value of education in research methods and the importance of supportive leadership. Education is an important factor in the employment of head nurses. We recommend interventions to create increased support for EBP among management, the goal being to deliver high-quality care and increase patient satisfaction.

    Strengthening public health systems has been a concern in Canada in the wake of public health emergencies. In one Canadian province, British Columbia, a high priority has been placed on the role of evidence to guide decision making; however, there are numerous challenges to using evidence in practice. The National Collaborating Centre for Methods and Tools therefore developed the Evidence Informed Public Health Framework (EIPH), a seven step guide to assist public health practitioners to use evidence in practice. We used this framework to examine the evidence literacy of public health practitioners in BC. We conducted a secondary analysis of two separate qualitative studies on the public health renewal process in which the use and understanding of evidence were key interview questions. Using constant comparative analysis, we analyzed the evidence-related data, mapping it to the categories of the EIPH framework. Participants require both data and evidence for multiple purposes in their daily work; data may be more important to them than research evidence. They are keen to provide evidence-based programs in which research evidence is balanced with community knowledge and local data. Practitioners recognise appraisal as an important step in using evidence, but the type of evidence most often used in daily practice does not easily lend itself to established methods for appraising research evidence. In the synthesis stage of the EIPH process, synthesized evidence in the form of systematic reviews and practice guidelines is emphasized. Participants, however, need to synthesize across the multiple forms of evidence they use and see the need for more skill and resources to help them develop skill in this type of synthesis. Public health practitioners demonstrated a good level of evidence literacy, particularly at the collective level in the organization. The EIPH framework provides helpful guidance in how to use research evidence in practice, but it lacks support on

    Systematic reviews that collate data about the relative effects of multiple interventions via network meta-analysis are highly informative for decision-making purposes. A network meta-analysis provides two types of findings for a specific outcome: the relative treatment effect for all pairwise comparisons, and a ranking of the treatments. It is important to consider the confidence with which these two types of results can enable clinicians, policy makers and patients to make informed decisions. We propose an approach to determining confidence in the output of a network meta-analysis. Our proposed approach is based on methodology developed by the Grading of Recommendations Assessment, Development and Evaluation (GRADE) Working Group for pairwise meta-analyses. The suggested framework for evaluating a network meta-analysis acknowledges (i) the key role of indirect comparisons (ii) the contributions of each piece of direct evidence to the network meta-analysis estimates of effect size; (iii) the importance of the transitivity assumption to the validity of network meta-analysis; and (iv) the possibility of disagreement between direct evidence and indirect evidence. We apply our proposed strategy to a systematic review comparing topical antibiotics without steroids for chronically discharging ears with underlying eardrum perforations. The proposed framework can be used to determine confidence in the results from a network meta-analysis. Judgements about evidence from a network meta-analysis can be different from those made about evidence from pairwise meta-analyses. PMID:24992266

    2017-06-01

    For many nurses and other health care practitioners, implementing evidence-based practice (EBP) presents two interlinked challenges: acquisition of EBP skills and adoption of evidence-based interventions and abandonment of ingrained non-evidence-based practices. The purpose of this study to describe two modes of learning and use these as lenses for analyzing the challenges of implementing EBP in health care. The article is theoretical, drawing on learning and habit theory. Adaptive learning involves a gradual shift from slower, deliberate behaviors to faster, smoother, and more efficient behaviors. Developmental learning is conceptualized as a process in the "opposite" direction, whereby more or less automatically enacted behaviors become deliberate and conscious. Achieving a more EBP depends on both adaptive and developmental learning, which involves both forming EBP-conducive habits and breaking clinical practice habits that do not contribute to realizing the goals of EBP. From a learning perspective, EBP will be best supported by means of adaptive learning that yields a habitual practice of EBP such that it becomes natural and instinctive to instigate EBP in appropriate contexts by means of seeking out, critiquing, and integrating research into everyday clinical practice as well as learning new interventions best supported by empirical evidence. However, the context must also support developmental learning that facilitates disruption of existing habits to ascertain that the execution of the EBP process or the use of evidence-based interventions in routine practice is carefully and consciously considered to arrive at the most appropriate response. © 2017 Sigma Theta Tau International.

    Health IT is expected to have a positive impact on the quality and efficiency of health care. But reports on negative impact and patient harm continue to emerge. The obligation of health informatics is to make sure that health IT solutions provide as much benefit with as few negative side effects as possible. To achieve this, health informatics as a discipline must be able to learn, both from its successes as well as from its failures. To present motivation, vision, and history of evidence-based health informatics, and to discuss achievements, challenges, and needs for action. Reflections on scientific literature and on own experiences. Eight challenges on the way towards evidence-based health informatics are identified and discussed: quality of studies; publication bias; reporting quality; availability of publications; systematic reviews and meta-analysis; training of health IT evaluation experts; translation of evidence into health practice; and post-market surveillance. Identified needs for action comprise: establish health IT study registers; increase the quality of publications; develop a taxonomy for health IT systems; improve indexing of published health IT evaluation papers; move from meta-analysis to meta-summaries; include health IT evaluation competencies in curricula; develop evidence-based implementation frameworks; and establish post-marketing surveillance for health IT. There has been some progress, but evidence-based health informatics is still in its infancy. Building evidence in health informatics is our obligation if we consider medical informatics a scientific discipline.

    The Common Drug Review (CDR) was created to provide a single process to review the comparative clinical efficacy and cost effectiveness of new drugs, and then to make formulary listing recommendations to Canadian publicly funded drug benefit plans. The objective was to conduct an in-depth analysis of Canadian Expert Drug Advisory Committee (CEDAC) recommendations to date, to explore predictors and possible explanatory factors associated with negative recommendations. Final recommendations were identified from inception (September 2003) to 31 December 2009. Using only publicly available information, recommendations were analysed under the following categories: submission specifics, drug characteristics, clinical factors and economic factors. Descriptive analyses were conducted, followed by statistical analyses, to determine which factors independently predicted a 'do not list' (DNL) recommendation. The database consisted of 138 unique final recommendations. The overall DNL rate was 48%. Significant differences in DNL rates were observed between therapeutic areas, ranging from 0% for HIV antivirals up to 88% for analgesic drugs. In the univariate analysis, several factors were significantly associated with a DNL recommendation, including first-in-class drugs and use of clinical scales as an outcome. In the multivariate regression, four factors were significantly predictive of a DNL recommendation: clinical uncertainty (odds ratio [OR] 14), price higher than comparators (OR 9), request for reconsideration (OR 10) and price as the only economic evidence used (OR 18). Incremental cost-effectiveness thresholds were not predictive of recommendations. The hypothesis that economic factors did not impact recommendations when clinical factors were included first was supported by the analysis. This analysis documented an evidence-driven process that simultaneously weighted multiple factors. Clinical uncertainty and price considerations, but not economic results, had a strong

    Rapid eye movement (REM) sleep behavior disorder (RBD) is characterized by dream enactment behavior resulting from a loss of REM skeletal muscle atonia. The neurobiology of REM sleep and the characteristic features of REM atonia have an important basis for understanding the aggravating etiologies the proposed pharmacological interventions in its management. This review outlines the evidence for behavioral and therapeutic measures along with evidence-based guidelines for their implementation, impact on falls, and effect on polysomnography (PSG) while highlighting the non-motor, autonomic, and cognitive impact of this entity. PubMed databases were reviewed upto May 2013 in peer-reviewed scientific literature regarding the pathophysiology and management of RBD in adults. The literature was graded according to the Oxford centre of evidence-based Medicine Levels. An early intervention that helps prevent consequences such as falls and provides a base for intervention with neuroprotective mechanisms and allocates a unique platform that RBD portrays with its high risk of disease conversion with a sufficiently long latency. RBD provides a unique platform with its high risk of disease conversion with a sufficiently long latency, providing an opportunity for early intervention both to prevent consequences such as falls and provide a base for intervention with neuroprotective mechanisms.

    Practice habits continue in clinical practice despite the availability of research and other forms of evidence that should be used to guide critical care practice interventions. This article is based on a presentation at the 2014 National Teaching Institute of the American Association of Critical-Care Nurses. The article is part of a series of articles that challenge critical care nurses to examine the evidence guiding nursing practice interventions. Four common practice interventions are reviewed: (1) weight-based medication administration, (2) chest tube patency maintenance, (3) daily interruption of sedation, and (4) use of chest physiotherapy in children. For weight-based administration of medication, the patient's actual weight should be measured, rather than using an estimate. The therapeutic effectiveness and dosages of medications used in obese patients must be critically evaluated. Maintaining patency of chest tubes does not require stripping and milking, which probably do more harm than good. Daily interruption of sedation and judicious use of sedatives are appropriate in most patients receiving mechanical ventilation. Traditional chest physiotherapy does not help children with pneumonia, bronchiolitis, or asthma and does not prevent atelectasis after extubation. Critical care nurses are challenged to evaluate their individual practice and to adopt current evidence-based practice interventions into their daily practice. ©2015 American Association of Critical-Care Nurses.

    Full Text Available Abstract Objective – The primary objective was to examine online journal database usage statistics for a provincial ministry of health in the context of evidence based decision-making. In addition, the study highlights implementation of the Journal Access Centre (JAC that is housed and powered by the Ontario Ministry of Health and Long-Term Care (MOHLTC to inform health systems policy-making. Methods – This was a prospective case study using descriptive analysis of the JAC usage statistics of journal articles from January 2009 to September 2013. Results – JAC enables ministry employees to access approximately 12,000 journals with full-text articles. JAC usage statistics for the 2011-2012 calendar years demonstrate a steady level of activity in terms of searches, with monthly averages of 5,129. In 2009-2013, a total of 4,759 journal titles were accessed including 1,675 journals with full-text. Usage statistics demonstrate that the actual consumption was over 12,790 full-text downloaded articles or approximately 2,700 articles annually. Conclusion – JAC’s steady level of activities, revealed by the study, reflects continuous demand for JAC services and products. It testifies that access to online journal databases has become part of routine government knowledge management processes. MOHLTC’s broad area of responsibilities with dynamically changing priorities translates into the diverse information needs of its employees and a large set of required journals. Usage statistics indicate that MOHLTC information needs cannot be mapped to a reasonably compact set of “core” journals with a subsequent subscription to those.

    Full Text Available The resurgence of bed bugs in major urban centres in North America has resulted in conflict between landlords and tenants. This is commonly focused on attribution of blame for source of infestation, on responsibility, on costs for preparation, treatment and losses, and for compensation as rent abatement and/or alternative temporary housing. In Ontario, Canada, these issues are often decided by adjudicators at the Landlord and Tenant Board hearing claims, counter-claims and defense by legal representation (lawyers and paralegals as well as through mediation. Evidence in these hearings may include photographs, invoices for costs as well as testimony by tenants, landlords and “expert witnesses” who are most often pest control firms representing their landlord clients.

  8. Evidence-based medicine: what is the evidence that it has made a difference?

    Science.gov (United States)

    2011-07-01

    Evidence-based medicine (EBM) has, over the past 20 years, made us all more critical in our thinking about the efficacy and safety of interventions. This is evident in the higher standards of our spoken and written work, formal and informal, and in our approach to the subject. The downside has been the coincidence of the squeeze on healthcare funding with the emergence of the EBM ideas - it has been all too easy to misuse the tools of EBM to deny patients access to treatment, and this, together with the off-putting political correctness of the EBM approach in some quarters, has made clinicians uneasy. Clinicians have to make decisions about therapy for the individual patient. Ideally this is guided by the best available evidence and their experience. EBM can guide one as to the population efficacy and safety of a particular intervention, but as we all know few patients are average. That guidance can only be given if there is adequate evidence, and the difficulty with guidance about symptom control is often the paucity of evidence of sufficient quality to yield credible guidance. Palliative care is often a 'complex intervention', and here EBM struggles to untangle which components, if any, of the complex interventions are important. The trial and review methodologies for complex intervention are wanting. Tom Chalmers, a grandfather of the EBM movement, argued late in his career that the most important function of the EBM approach was to frame the research agenda. This we think is correct. The process of systematic review of a topic throws up the deficits in trial methods and the lacunae in the data, and this then can show the way forward.

    Evidence-based medicine is the conscientious and judicious use of current best knowledge in making decisions about the care of individual patients, often from well-designed, randomized, controlled trials. Authoritative medicine is the traditional approach to learning and practicing medicine, but no one authority has comprehensive scientific knowledge. Archie Cochrane proposed that every medical specialty should compile a list of all of the randomized, controlled trials within its field to be available for those who wish to know what treatments are effective. This was done first for obstetrics by a group collecting and critically analyzing all of the randomized trials and then indicating procedures every mother should have and those that no mother should have. Support during labor was used as an example. Similar groups are now active in almost all specialties, with information available on the Internet in the Cochrane Database of Systematic Reviews. Developmental-behavioral pediatrics should be part of this movement to evidence-based medicine.

    2013-01-01

    Evidence-based medicine (EBM) as a health care practice is being incorporated into education programs across the spectrum of medical education to develop lifelong learning skills and to enhance the practice of evidence-based health care. Since improving the quality of patient care is the ultimate goal of EBM, EBM learning must be integrated with clinical application, and resulted outcomes must be reflected in learning transfer (or EBM practice) within the context of solving patient problems. Different factors may constitute the context or environment in which EBM is learned, practiced, and sustained. However, these contextual factors are seldom considered and examined in the development, implementation, and evaluation of EBM instruction for learners at different levels. This article will introduce several contextual factors as tips and strategies that affect EBM learning and transfer. Also included in the article are recommended practices for designing effective EBM instruction that would contribute to a sustainable change in learner behavior.

    In this closing article of the special issue, we present the conclusions and recommendations of the interdivisional task force on evidence-based therapy relationships. The work was based on a series of meta-analyses conducted on the effectiveness of various relationship elements and methods of treatment adaptation. A panel of experts concluded that several relationship elements were demonstrably effective (alliance in individual psychotherapy, alliance in youth psychotherapy, alliance in family therapy, cohesion in group therapy, empathy, collecting client feedback) while others were probably effective (goal consensus, collaboration, positive regard). Three other relationship elements (congruence/genuineness, repairing alliance ruptures, and managing countertransference) were deemed promising but had insufficient evidence to conclude that they were effective. Multiple recommendations for practice, training, research, and policy are advanced. (PsycINFO Database Record (c) 2011 APA, all rights reserved).

    Injections are routinely administered by nurses in acute care settings and in the community. Nurses require a thorough understanding of anatomy and physiology, pharmacological principles and equipment, and potential risks to the patient of injections. Nurses should also take an active approach to patient assessment before injecting medicines. This article, the first of two, provides an evidence-based review of injection administration, with particular reference to subcutaneous injections, and suggests a framework for best practice.

    Full Text Available Abstract Objective: To analyze the apprehensions of nurse managers in the implementation of the Evidence Based Practice in a Teaching Hospital of Triângulo Mineiro. Method: Qualitative research guided by the Theory of the Diffusion of Innovations. Five workshops were conducted per focal group (n = 18 participants, conducted by hermeneutic-dialectic interactions between August and September/2016. Textual records resulting from each workshop were analyzed by semantic categories. Results: Aspects conditioning to the implementation of the Evidence Based Practice permeate from elements related to the fragmentation of the care network to the necessary expansion of the governability of the nurse managers to put changes into practice in their sectors. Most importantly, timely access to the results of research conducted at the teaching hospital was mentioned as crucial to guide better practices. Final considerations: The approach allowed the recognition of contextual conditions for the implementation of the Evidence-Based Practice, which may coincide with similar scenarios, as well as increase the national scientific production on the subject, which is still scarce.

    (EBME) [corrected] is an attitude of mind that entails the creation of a culture in which teachers think critically about what they are doing, look at the best evidence available and on this basis, make decisions about their teaching practice, and subsequently, undertake the necessary revision and change. More medical schools have opened in Saudi Arabia in the last few years than have existed over the last three decades. Currently, the education of health professionals is based on assumption and traditions and rarely on research findings. Medical teaching has evolved from being opinion-based to evidence-based and the art of teaching is rapidly becoming the 'science' of teaching. The need for evidence in our teaching and medical education practices is as important as it is in assessing a new therapy. This approach to education is not only associated with better results in terms of better learning, from the side of the students (the consumers), but also has a wider impact on patient care and the community. Moreover, in this age of accountability, litigations and quality assurance, the need for BEME becomes greater. Some suggestions to implement BEME in Saudi Arabia have been put forward and these are the training of medical education professionals in the use the existing information systems, and disseminating information through the creation of a BEME journal (secondary publication) that publishes a critically appraised summary of medical education articles that are both valid and of immediate clinical use.

    Although we are in the era of evidence-based medicine, there is still a substantial gap between theory and current practice with the application of reference intervals as decision making tools. Different laboratories may have different reference intervals for the same tests using the same analytical methods and platforms. These differences have the potential to confuse physicians making the assessment and monitoring of patients more difficult by providing discordant information. This paper attempts to demonstrate how to use evidence-based approach for harmonising reference intervals. In order to consider harmonisation we must first have an appreciation of the various factors that influence the determination of that reference interval such as the choice of individuals within the population studied, biological variability of the analyte studied, partitioning, sample collection, analytical aspects such as bias and statistical models. An a priori approach for determining reference intervals, whilst recommended, may be beyond the scope of most laboratories and consideration should be given to the use of a validated indirect a posteriori approach. Regardless of method used, the continuing application of an evidence-based approach in harmonised reference intervals to meet the quality expectations of physicians should be pursued. © 2013.

  19. The Developing Role of Evidence-Based Environmental Health

    2015-10-01

    Full Text Available There has been renewed recognition that proactive strategies and interventions can address the social determinants of health, and the environmental health profession is well placed to effect positive change in many of these determinants. This qualitative research has revealed differences in the perceptions, experiences, and understandings of evidence-based practice among public health professionals from different backgrounds across different services in health care and local government in England. The absence of a strong tradition of evidence-based practice in environmental health appears to be a disadvantage in securing funding and playing a full role, as it has become the expectation in the new public health system. This has, at times, resulted in tensions between professionals with different backgrounds and frustration on the part of environmental health practitioners, who have a tradition of responding quickly to new challenges and “getting on with the job.” There is generally a willingness to develop evidence-based practice in environmental health; however, this will take time and investment.

    2018-02-21

    A strong foundation in physical conditioning and sport-specific experience, in addition to a bespoke and periodized training and nutrition program, are essential for athlete development. Once these underpinning factors are accounted for, and the athlete reaches a training maturity and competition level where marginal gains determine success, a role may exist for the use of evidence-based performance supplements. However, it is important that any decisions surrounding performance supplements are made in consideration of robust information that suggests the use of a product is safe, legal, and effective. The following review focuses on the current evidence-base for a number of common (and emerging) performance supplements used in sport. The supplements discussed here are separated into three categories based on the level of evidence supporting their use for enhancing sports performance: (1) established (caffeine, creatine, nitrate, beta-alanine, bicarbonate); (2) equivocal (citrate, phosphate, carnitine); and (3) developing. Within each section, the relevant performance type, the potential mechanisms of action, and the most common protocols used in the supplement dosing schedule are summarized.

    This paper discusses the integration of evidence-based design (EBD) into the design process as an innovation, illuminates the significance and progress of the diffusion of this innovation, and identifies EBD advocates and the consequences of meeting the EBD challenge. A free tool for engaging in EBD is explored. Healthcare designers are leading the EBD charge, because their clients depend on it. But not all designers engage in EBD, because it may be beyond the resources of a firm or outside its culture. However, as with other meaningful design innovations, designers who do not practice EBD could fall by the wayside. EBD is a product of the diffusion of the innovation of evidence-based medicine. The academy (i.e., the collective of institutions of higher education), design organizations, design communities, and the media all contribute to the diffusion of EBD. However, the quantity, quality, and understandability of evidence continue to challenge its broad adoption. InformeDesign®, a free, Internet-based tool, presents information to designers in a concise, understandable way. Firms must invest in EBD incrementally as a value-added component of design to meet current and future challenges. It is important for designers to realize that engaging in EBD is not a rejection of creativity, but a means by which to elevate their design solutions. ©2009 VENDOME GROUP, LLC

    Neuropsychology is poised for transformations of its concepts and methods, leveraging advances in neuroimaging, the human genome project, psychometric theory, and information technologies. It is argued that a paradigm shift towards evidence-based science and practice can be enabled by innovations, including: (1) formal definition of neuropsychological concepts and tasks in cognitive ontologies; (2) creation of collaborative neuropsychological knowledgebases; and (3) design of web-based assessment methods that permit free development, large-sample implementation, and dynamic refinement of neuropsychological tests and the constructs these aim to assess. This article considers these opportunities, highlights selected obstacles, and offers suggestions for stepwise progress towards these goals. PMID:21092355

    Full Text Available Objective. To perform an evidence-based review of treatments for Toxoplasma retinochoroiditis (TRC. Methods. A systematic literature search was performed using the PubMed database and the key phrase “ocular toxoplasmosis treatment” and the filter for “controlled clinical trial” and “randomized clinical trial” as well as OVID medline (1946 to May week 2 2014 using the keyword ‘‘ocular toxoplasmosis’’. The included studies were used to evaluate the various treatment modalities of TRC. Results. The electronic search yielded a total of 974 publications of which 44 reported on the treatment of ocular toxoplasmosis. There were 9 randomized controlled studies and an additional 3 comparative studies on the treatment of acute TRC with systemic or intravitreous antibiotics or on reducing the recurrences of TRC. Endpoints of studies included visual acuity improvement, inflammatory response, lesion size changes, recurrences of lesions, and adverse effects of medications. Conclusions. There was conflicting evidence as to the effectiveness of systemic antibiotics for TRC. There is no evidence to support that one antibiotic regimen is superior to another so choice needs to be informed by the safety profile. Intravitreous clindamycin with dexamethasone seems to be as effective as systemic treatments. There is currently level I evidence that intermittent trimethoprim-sulfamethoxazole prevents recurrence of the disease.

    2012-09-01

    Drugs are estimated to cause about 10 - 25% of all cases of gynecomastia. Over the course of several decades, multiple medications have been implicated in the development of gynecomastia mostly in the form of case reports and case series. However, these reports suffer from a multitude of deficiencies, including poor quality of evidence. Studies were selected for this review by performing an extensive electronic and hand-search using BIOSIS, EMBASE and Medline, from 1940 to present, for all reported drug associations of gynecomastia and their possible pathophysiology. Quality of evidence was assessed on a three-point scale: good, fair and poor, and each of the drugs reported to cause gynecomastia was assigned a level of strength. The pathophysiology of gynecomastia is also discussed in detail for each of the drugs found to have a good or fair evidence of association with gynecomastia. Most of the reported drug-gynecomastia associations were based on poor quality evidence. The drugs definitely associated with the onset of gynecomastia are spironolactone, cimetidine, ketoconazole, hGH, estrogens, hCG, anti-androgens, GnRH analogs and 5-α reductase inhibitors. Medications probably associated with gynecomastia include risperidone, verapamil, nifedipine, omeprazole, alkylating agents, HIV medications (efavirenz), anabolic steroids, alcohol and opioids.

    The scope of pharmacist services for patients with pulmonary disease has primarily focused on drug related outcomes; however pharmacists have the ability to broaden the scope of clinical services by performing diagnostic testing including quality spirometry testing. Studies have demonstrated that pharmacists can perform quality spirometry testing based upon international guidelines. The primary aim of this review was to assess the published evidence of pharmacists performing quality spirometry testing based upon American Thoracic Society/European Respiratory Society (ATS/ERS) guidelines. In order to accomplish this, the description of evidence and type of outcome from these services were reviewed. A literature search was conducted using five databases [PubMed (1946-January 2015), International Pharmaceutical Abstracts (1970 to January 2015), Cumulative Index of Nursing and Allied Health Literature, Cochrane Central Register of Controlled Trials and Cochrane Database of Systematic Reviews] with search terms including pharmacy, spirometry, pulmonary function, asthma or COPD was conducted. Searches were limited to publications in English and reported in humans. In addition, Uniform Resource Locators and Google Scholar searches were implemented to include any additional supplemental information. Eight studies (six prospective multi-center trials, two retrospective single center studies) were included. Pharmacists in all studies received specialized training in performing spirometry testing. Of the eight studies meeting inclusion and exclusion criteria, 8 (100%) demonstrated acceptable repeatability of spirometry testing based upon standards set by the ATS/ERS guidelines. Acceptable repeatability of seven studies ranged from 70 to 99% consistent with published data. Available evidence suggests that quality spirometry testing can be performed by pharmacists. More prospective studies are needed to add to the current evidence of quality spirometry testing performed by

    Key roles in teaching evidence-based practice (EBP) are of interest to many hospital and academic librarians. This article describes how three academic librarians, in collaboration with the academic medical center's EBP Nursing Council, developed a seminar consisting of three credit hours of instruction in the basics of evidence-based practice. The seminar consists of three core elements: basic principles of EBP and finding literature, clinical experience and integration of knowledge into the hospital setting, and patient education and participation. Emphasis is placed upon analysis of the literature, institutional models of practice change, and the importance of patient roles in guideline development.

    This study was designed to adapt a surgical wound care algorithm that is used to provide evidence-based surgical wound care in a critical care unit. This study used, the 'ADAPTE process', an international clinical practice guideline development method. The 'Bonnie Sue wound care algorithm' was used as a draft for the new algorithm. A content validity index (CVI) targeting 135 critical care nurses was conducted. A 5-point Likert scale was applied to the CVI test using a statistical criterion of .75. A surgical wound care algorithm comprised 9 components: wound assessment, infection control, necrotic tissue management, wound classification by exudates and depths, dressing selection, consideration of systemic factors, wound expected outcome, reevaluate non-healing wounds, and special treatment for non-healing wounds. All of the CVI tests were ≥.75. Compared to existing wound care guidelines, the new wound care algorithm provides precise wound assessment, reliabilities of wound care, expands applicability of wound care to critically ill patients, and provides evidence and strength of recommendations. The new surgical wound care algorithm will contribute to the advancement of evidence-based nursing care, and its use is expected as a nursing intervention in critical care.

    Full Text Available Abstract Background Infertility is defined as inability of a couple to conceive naturally after one year of regular unprotected sexual intercourse. It remains a major clinical and social problem, affecting perhaps one couple in six. Evaluation usually starts after 12 months; however it may be indicated earlier. The most common causes of infertility are: male factor such as sperm abnormalities, female factor such as ovulation dysfunction and tubal pathology, combined male and female factors and unexplained infertility. Objectives The aim of this study is to provide the healthcare professionals an evidence-based management protocol for infertile couples away from medical information overload. Methods A comprehensive review where the literature was searched for "Management of infertility and/or infertile couples" at library website of University of Bristol (MetaLib by using a cross-search of different medical databases besides the relevant printed medical journals and periodicals. Guidelines and recommendations were retrieved from the best evidence reviews such as that from the American College of Obstetricians and Gynaecologists (ACOG, American Society for Reproductive Medicine (ASRM, Canadian Fertility and Andrology Society (CFAS, and Royal College of Obstetricians and Gynaecologists (RCOG. Results A simple guide for the clinicians to manage the infertile couples. Conclusions The study deploys a new strategy to translate the research findings and evidence-base recommendations into a simplified focused guide to be applied on routine daily practice. It is an approach to disseminate the recommended medical care for infertile couple to the practicing clinicians.

    2016-12-01

    The US Food and Drug Administration (FDA) approved 10 new drugs for the treatment of multiple myeloma (MM) over the last two decades. The influx of new anti-myeloma agents with high efficacy and acceptable tolerability add complexity to the clinical decision-making process. First, treatment of smoldering multiple myeloma (SMM) remains investigational to date, although a randomized trial showed a survival gain in high-risk patients receiving lenalidomide. Second, in newly diagnosed MM, the majority of contemporary induction regimens have been studied in single-arm trials or compared to an older regimen, which complicates evidence-based treatment selection. Third, the role of consolidation chemotherapy followed by autologous stem cell transplant (ASCT) needs to be revisited in the context of highly effective agents, as newer regimens- such as carfilzomib, lenalidomide, and dexamethasone-are able to achieve extremely deep responses equivalent to or exceeding those seen after conventional induction and ASCT. Fourth, risks and benefits of maintenance therapy should also be redefined and individualized, as long-term survival and safety data accumulate. Here we selected four clinical settings where controversies exist, reviewed evidences behind conflicting treatment strategies, and asked myeloma experts to discuss evidence-based recommendations.

    2007-03-01

    This project identified evidence-based psychotherapy treatments for anxiety disorders in older adults. The authors conducted a review of the geriatric anxiety treatment outcome literature by using specific coding criteria and identified 17 studies that met criteria for evidence-based treatments (EBTs). These studies reflected samples of adults with generalized anxiety disorder (GAD) or samples with mixed anxiety disorders or symptoms. Evidence was found for efficacy for 4 types of EBTs. Relaxation training, cognitive-behavioral therapy (CBT), and, to a lesser extent, supportive therapy and cognitive therapy have support for treating subjective anxiety symptoms and disorders. CBT for late-life GAD has garnered the most consistent support, and relaxation training represents an efficacious, relatively low-cost intervention. The authors provide a review of the strengths and limitations of this research literature, including a discussion of common assessment instruments. Continued investigation of EBTs is needed in clinical geriatric anxiety samples, given the small number of available studies. Future research should examine other therapy models and investigate the effects of psychotherapy on other anxiety disorders, such as phobias and posttraumatic stress disorder in older adults.

  14. Evidence-based therapies for upper extremity dysfunction.

    Liepert, Joachim

    2010-12-01

    The diversity of interventions aimed at improving upper extremity dysfunction is increasing. This article reviews the effectiveness of different therapeutic approaches that have been published in 2009 and 2010. Evidence is based on randomized controlled trials, systematic reviews, and meta-analyses. Application of constraint-induced movement therapy in acute stroke patients was not more effective than a control intervention, and a more intense therapy may even be harmful. Botulinum toxin injections do not only reduce spasticity but, in children, also improve motor functions if combined with occupational therapy. Strength training improves arm function but not necessarily activities of daily living. Bilateral arm training is as effective as other interventions. Extrinsic feedback and sensory training may further improve motor functions. Mirror therapy was particularly effective for patients with initial hand plegia. For some interventions (e.g. constraint-induced movement therapy, botulinum toxin), efficacy is evident, for others (e.g. mental practice, virtual reality), well designed studies with sufficient numbers of patients are needed. The ultimate goal still is to develop evidence-based therapies for all different degrees of motor impairment.

    The purpose of this project was to explore nurses' willingness to question and change practice. Nurses were invited to report practice improvement opportunities, and participants were supported through the process of a practice change. The project leader engaged to the extent desired by the participant. Meetings proceeded until the participant no longer wished to continue, progress was blocked, or practice was changed. Evaluation of the evidence-based practice change process occurred. Fifteen nurses reported 23 practice improvement opportunities. The majority (12 of 15) preferred to have the project leader review the evidence. Fourteen projects changed practice; 4 were presented at conferences. Multiple barriers were identified throughout the process and included loss of momentum, the proposed change involved other disciplines, and low level or controversial evidence. Practice issues were linked to quality metrics, cost of care, patient satisfaction, regulatory compliance, and patient safety. Active engagement by nurse leaders was needed for a practice change to occur. Participants identified important problems previously unknown to hospital administrators. The majority of nurses preferred involvement in practice change based on clinical problem solving when supported by others to provide literature review and manage the process through committees. Recommendations include supporting a culture that encourages employees to report practice improvement opportunities and provide resources to assist in navigating the identified practice change.

    Antiepileptic drugs (AEDs) have many benefits but also many side effects, including aggression, agitation, and irritability, in some patients with epilepsy. This article offers a comprehensive summary of current understanding of aggressive behaviors in patients with epilepsy, including an evidence-based review of aggression during AED treatment. Aggression is seen in a minority of people with epilepsy. It is rarely seizure related but is interictal, sometimes occurring as part of complex psychiatric and behavioral comorbidities, and it is sometimes associated with AED treatment. We review the common neurotransmitter systems and brain regions implicated in both epilepsy and aggression, including the GABA, glutamate, serotonin, dopamine, and noradrenaline systems and the hippocampus, amygdala, prefrontal cortex, anterior cingulate cortex, and temporal lobes. Few controlled clinical studies have used behavioral measures to specifically examine aggression with AEDs, and most evidence comes from adverse event reporting from clinical and observational studies. A systematic approach was used to identify relevant publications, and we present a comprehensive, evidence-based summary of available data surrounding aggression-related behaviors with each of the currently available AEDs in both adults and in children/adolescents with epilepsy. A psychiatric history and history of a propensity toward aggression/anger should routinely be sought from patients, family members, and carers; its presence does not preclude the use of any specific AEDs, but those most likely to be implicated in these behaviors should be used with caution in such cases.

    2011-01-01

    Full Text Available Evidence-based medicine (EBM is not a old hat, a "cookbook" medicine perpetrated by arrogant to serve cost cutters to suppress clinical freedom, a mandatory, deterministic, totalitarian practice of medicine, a way to control cost and to ignore patient preferences, a limit to personal/humanistic/individual medicine. EBM is a reference of excellence to guide clinical decisions, the integration of own expertise with others' expertise and patient preferences, a way to improve medical practice and limit the variability and errors created when there is not evidence to identify the gold standard and differentiate among alternatives available. But evidences need to be integrated with a new thinking based on Complexity Science. Health care systems operates as complex adaptative systems rather than rigid, linear or mechanical organizations and innovation is a critical outcome of Complexity Science. How does EBM impact drug innovation? New drug approvals are not keeping pace with rising Research and Development spending, clinical approval success rate for new chemical entities (NCEs is progressively dropping and maybe, through these indicators, we are seeing the worst face of EBM: its limiting, blocking, and controlling side. If that is the case, EBM is the main ally to keep the economy of health systems under control and the great excuse to block the access of the innovation to patients. Certainly not the best way to maximize the benefits of EBM.

    Objective To identify and clarify current evidence supporting and disputing the effectiveness of perioperative antibiotic use for common otolaryngology procedures. Data Sources PubMed, Embase (OVID), and CINAHL (EBSCO). Review Methods English-language, original research (systematic reviews/meta-analyses, randomized control trials, prospective or retrospective cohort studies, case-control studies, or case series) studies that evaluated the role of perioperative antibiotic use in common otolaryngology surgeries were systematically extracted using standardized search criteria by 2 investigators independently. Conclusions Current evidence does not support routine antibiotic prophylaxis for tonsillectomy, simple septorhinoplasty, endoscopic sinus surgery, clean otologic surgery (tympanostomy with tube placement, tympanoplasty, stapedectomy, and mastoidectomy), and clean head and neck surgeries (eg, thyroidectomy, parathyroidectomy, salivary gland excisions). Antibiotic prophylaxis is recommended for complex septorhinoplasty, skull base surgery (anterior and lateral), clean-contaminated otologic surgery (cholesteatoma, purulent otorrhea), and clean-contaminated head and neck surgery (violation of aerodigestive tract, free flaps). In these cases, antibiotic use for 24 to 48 hours postoperatively has shown equal benefit to longer duration of prophylaxis. Despite lack of high-quality evidence, the US Food and Drug Administration suggests antibiotic prophylaxis for cochlear implantation due to the devastating consequence of infection. Data are inconclusive regarding postoperative prophylaxis for nasal packing/splints after sinonasal surgery. Implications for Practice Evidence does not support the use of perioperative antibiotics for most otolaryngologic procedures. Antibiotic overuse and variability among providers may be due to lack of formal practice guidelines. This review can help otolaryngologists understand current evidence so they can make informed decisions about

Among the elderly, STF is the risk factor that causes the largest number of inpatient days...... at hospitals. It is the argued that prevention of STF is insufficient and that the reason is insufficient evidence on incidence rates, the causes and the health impact of STF related injuries.

STF in the injury model is considered not as an injury, but as a pre-event of an injury and in most cases a near miss without injury.

    Full Text Available Various interventions are used in clinical practice to address insecure or disorganized attachment patterns and attachment disorders. The most common of these are parenting interventions, but not all have a robust empirical evidence base. We undertook a systematic review of randomized trials comparing a parenting intervention with a control, where these used a validated attachment instrument, in order to evaluate the clinical and cost-effectiveness of interventions aiming to improve attachment in children with severe attachment problems (mean age <13 years. This article aims to inform clinicians about the parenting interventions included in our systematic review that were clinically effective in promoting secure attachment. For completeness, we also briefly discuss other interventions without randomized controlled trial evidence, identified in Patient Public Involvement workshops and expert groups at the point our review was completed as being used or recommended. We outline the key implications of our findings for clinical practice and future research.

    Evidence-based medicine (EBM) refers to the conscientious, explicit and judicious use of current best evidence from research for the care of an individual patient. The concept of EBM was first described in human medicine in the early 1990s and was introduced to veterinary medicine 10 years later. However, it is not clear that the EBM approach promulgated in human medicine can be applied to the same extent to veterinary medicine. EBM has the potential to help veterinarians to make more informed decisions, but obstacles to the implementation of EBM include a lack of high quality patient-centred research, the need for basic understanding of clinical epidemiology by veterinarians, the absence of adequate searching techniques and accessibility to scientific data bases and the inadequacy of EBM tools that can be applied to the busy daily practise of veterinarians. This review describes the development of EBM in the veterinary profession, identifies its advantages and disadvantages and discusses whether and how veterinary surgeons should further adopt the EBM approach of human medicine.

    pharmaceutical counseling standards: Article 1.1 "Code of Ethics of the pharmaceutical worker of Russia" states: "The main task of the professional activity of the pharmaceutical worker - protection of human health", Article 1.3 states that a pharmaceutical worker must take professional decisions solely in the interests of a patient [1]. However, the pharmacy is a trade organization, thus as a retailer the pharmacy is directly interested in making profits and increasing sales of pharmaceutical products, including non-prescription medicines. Moreover, while the clinical medicine is monitored for unjustified prescribing and measures are being taken to prevent polypharmacy, for a pharmacist the growing sales of over-the-counter drugs, active promotion of dietary supplements, homeopathic medicines, medical devices, and, consequently, an increase of financial indicators (particularly "average purchase size") - all are characteristics of success [2].Rational use of over-the-counter medicines requires introduction of pharmaceutical counseling standards (pharmaceutical care) according to symptoms - major reasons to visit a pharmacy as part of responsible self-medication (cold, sore throat, headache, diarrhea, etc.). Standards of pharmaceutical counseling should be objective, reliable and up-to-date and contain recommendations for the rational use of over-the-counter drugs as well as indications requiring treatment to the doctor. Standardization of pharmaceutical counseling in terms of Evidence-based Pharmacy would enhance the efficiency, safety and cost-effectiveness of over-the-counter medicines.Currently, the lack of clinical component in the higher pharmaceutical education and the lack of approved standards of pharmaceutical counseling lead to the introduction of cross-selling technologies (which are broadly applied in other areas of trade, for example, the offer of a boot-polish during the sale of shoes) to the pharmaceutical practice [2, 3]. However, drugs belong to a special group

  6. Evidence-based ethics – What it should be and what it shouldn't

    2008-10-01

    Full Text Available Abstract Background The concept of evidence-based medicine has strongly influenced the appraisal and application of empirical information in health care decision-making. One principal characteristic of this concept is the distinction between "evidence" in the sense of high-quality empirical information on the one hand and rather low-quality empirical information on the other hand. In the last 5 to 10 years an increasing number of articles published in international journals have made use of the term "evidence-based ethics", making a systematic analysis and explication of the term and its applicability in ethics important. Discussion In this article four descriptive and two normative characteristics of the general concept "evidence-based" are presented and explained systematically. These characteristics are to then serve as a framework for assessing the methodological and practical challenges of evidence-based ethics as a developing methodology. The superiority of evidence in contrast to other empirical information has several normative implications such as the legitimization of decisions in medicine and ethics. This implicit normativity poses ethical concerns if there is no formal consent on which sort of empirical information deserves the label "evidence" and which does not. In empirical ethics, which relies primarily on interview research and other methods from the social sciences, we still lack gold standards for assessing the quality of study designs and appraising their findings. Conclusion The use of the term "evidence-based ethics" should be discouraged, unless there is enough consensus on how to differentiate between high- and low-quality information produced by empirical ethics. In the meantime, whenever empirical information plays a role, the process of ethical decision-making should make use of systematic reviews of empirical studies that involve a critical appraisal and comparative discussion of data.

    Full Text Available We aimed to investigate the characteristics of patients with osteoarthritis (OA, using the data of all Koreans registered in the National Health Insurance Sharing Service Database (NHISS DB, and to provide ideal alternative cutoff thresholds for alleviating OA symptoms. Patients with OA (codes M17 and M17.1–M17.9 in the Korean Standard Classification of Disease and Causes of Death were analyzed using SAS software. Optimal cutoff thresholds were determined using receiver operating characteristic curve analysis. The 50-year age group was the most OA pathogenic group (among 40~70 years, n=2088. All exercise types affected the change of body mass index (p<0.05 and the sex difference in blood pressure (BP (p<0.01. All types of exercise positively affected the loss of waist circumference and the balance test (standing time on one leg in seconds (p<0.01. The cutoff threshold for the time in seconds from standing up from a chair to walking 3 m and returning to the same chair was 8.25 (80% sensitivity and 100% specificity. By using the exercise modalities, categorized multiple variables, and the cutoff threshold, an optimal alternative exercise program can be designed for alleviating OA symptoms in the 50-year age group.

    Full Text Available This paper describes the philosophy, development and framework of the body of elements formulated to provide an approach to evidence-based learning sustained by Learning Objects and web based technology Due to the demands for continuous improvement in the delivery of healthcare and in the continuous endeavour to improve the quality of life, there is a continuous need for practitioner's to update their knowledge by accomplishing accredited courses. The rapid advances in medical science has meant increasingly, there is a desperate need to adopt wireless schemes, whereby bespoke courses can be developed to help practitioners keep up with expanding knowledge base. Evidently, without current best evidence, practice risks becoming rapidly out of date, to the detriment of the patient. There is a need to provide a tactical, operational and effective environment, which allows professional to update their education, and complete specialised training, just-in-time, in their own time and location. Following this demand in the marketplace the information engineering group, in combination with several medical and dental schools, set out to develop and design a conceptual framework which form the basis of pioneering research, which at last, enables practitioner's to adopt a philosophy of life long learning. The body and structure of this framework is subsumed under the term Object oriented approach to Evidence Based learning, Just-in-time, via Internet sustained by Reusable Learning Objects (The OEBJIRLO Progression. The technical pillars which permit this concept of life long learning are pivoted by the foundations of object oriented technology, Learning objects, Just-in-time education, Data Mining, intelligent Agent technology, Flash interconnectivity and remote wireless technology, which allow practitioners to update their professional skills, complete specialised training which leads to accredited qualifications.

    2015-09-01

    The contrast between the efficiency of Evidence-Based Medicine (EBM), a scientific fact, and the popularity of Complementary and Alternative Medicines (CAM) is a paradox of the art of healing. EBM is based on the paradigm of positivism and materialism while CAM are based on those of relativism and vitalism. These paradigms are diametrically opposed and the aim of an integrative medicine is aporetic. However, EBM is today in a dead end. The objective proof of a disease according to the rules of EBM is often lacking face to the expectations of patients demanding their illness to be taken into account. EBM and CAM have thus to coexist. Lessons can be drawn from CAM : patient expectations should be given a meaning and be integrated in his or her psychosocial context.

    Schema Therapy is becoming an increasingly popular psychological model for working with individuals who have a variety of mental health and personality difficulties. The aim of this review is to look at the current evidence base for Schema Therapy and highlight directions for further research. A systematic search of the literature was conducted up until January 2011. All studies that had clinically tested the efficacy of Schema Therapy as described by Jeffrey Young (1994 and 2003) were considered. These studies underwent detailed quality assessments based on Scottish Intercollegiate Guidelines Network (SIGN-50) culminating in 12 studies being included in the review. The culminative message (both from the popularity of this model and the medium-to-large effect sizes) is of a theory that has already demonstrated clinically effective outcomes in a small number of studies and that would benefit from ongoing research and development with complex client groups. It is imperative that psychological practice be guided by high-quality research that demonstrates efficacious, evidence-based interventions. It is therefore recommended that researchers and clinicians working with Schema Therapy seek to build on these positive outcomes and further demonstrate the clinical effectiveness of this model through ongoing research.

    Although not without its critics, evidence-based practice is widely espoused as supporting professional nursing practice. Engaging with the evidence-based practice discourse from a vantage point offered by the critical perspectives of postcolonial feminism, the incomplete epistemologies and limitations of the standardization characteristic of the evidences-based movement are analyzed. Critical analysis of evidence is suggested, such that it recognizes the evidence generated from multiple paradigms of inquiry, along with contextual interpretation and application of this evidence. We examine how broader interpretations of evidence might contribute to nursing knowledge development and translation for transformative professional nursing practice, and ultimately to address persistent health disparities within the complex context of healthcare delivery.

    The young field of obesity surgery (bariatric surgery) in Germany expands as a consequence of the rapid increase of overweight and obesity. New surgical methods, minimal access techniques, and the enormous increase of scientific studies and evidence, all contribute to the success of bariatric surgery, which is the only realistic chance of permanent weight loss and regression of secondary diseases in many cases. A systematic literature review, classification of evidence, graded recommendations, and interdisciplinary consensus. Obesity surgery is an integral component of the multimodal treatment of obesity, which consists of multidisciplinary evaluation and preparation, conservative and surgical treatment elements, and a life-long follow-up. The guideline confirms the body mass index (BMI)-based spectrum of indications (BMI > 40 kg/m(2) or >35 kg/m(2) with secondary diseases) and extends it through elimination of all age restrictions (>18 years and <60 years) and most of the contraindications. Precondition for surgery is the failure of a structured conservative program of 6-12 months or the expected futility of it. Type II diabetes mellitus becomes an independent indication criterion for BMI < 35 kg/m(2) (metabolic surgery). The standard techniques are gastric balloon, gastric banding, gastric bypass, gastric sleeve, and biliopancreatic diversion. The choice of procedure is based on profound knowledge of results, long-term effects, complications, and patient-specific circumstances. The after-care should be structured and organized long term. The S3-guidelines contain evidence-based recommendations for the indication, selection of procedure, technique, and follow-up. Patient care should improve after implementation of these guidelines in clinical practice. Compliance by decision makers and health insurers is warranted.

    Military medical treatment facilities offer a unique environment in which to develop a culture of evidence-based practice (EBP). Distinctive issues arise in the context of changed patient care demographics because of a war-injured population. These issues offer an opportunity to enhance the quality of care through the use and adaptation of research findings in this special nursing environment. In addition, the colocation of two military medical centers offers the prospect of collaborative efforts to create a regional culture for nursing EBP. The purposes of this study were to describe the processes of a collaborative project to train nurses in EBP and to share resources in developing and implementing evidence-based clinical nursing guidelines in two large military medical centers in the Northeastern United States and to discuss the collective efforts of nurse researchers, leadership, advanced practice nurses, and staff nurses in each hospital to facilitate the EBP process. A description of the organizational structure and the climate for EBP of each facility is provided followed by discussion of training efforts and the inculcation of an organizational culture for EBP. Contextual barriers and facilitators were encountered throughout the project. The two nurse researchers leading the projects were able to overcome the barriers and capitalize on opportunities to promote EBP. Three evidence-based clinical practice guidelines were developed at each facility and are currently in various stages of implementation. Despite the barriers, EBP continues to be at the forefront of military nursing practice in the U.S. National Capital Region. Clear communication and regular meetings were essential to the success of the collaborative project within and between the two military hospitals. Military-specific barriers to EBP included high team attrition and turnover because of the war mission and the usual high staff turnover at military hospitals. Military facilitators included a

    Full Text Available Objective To formulate the best treatment plan for multiple sclerosis (MS patients by evaluating the therapeutic efficacy and side effect of various evidence-based programs. Methods Key words were defined as multiple sclerosis, immunomodulatory therapy and therapy, etc. We searched MEDLINE, Cochrane Library, Wanfang data bases for Scientific Journals in China and National Knowledge Infrastructure for Chinese Scientific Journals Database. Additionally, we applied manual searching and screened out conference paper and academic dissertation, etc, from various references. After that we obtained and evaluated by Jadad scales on systematic reviews, randomized controlled trials, controlled clinical trials and observational study cases about glucocorticoids, plasmapheresis, intravenous immunoglobulin, IFN-β, glatiramer acetate, mitoxantrone, natalizumab, fingolimod. Results After screening, all seventeen selected resources included systematic reviews 6 articles, randomized controlled trials 7 articles, controlled clinical trials 2 articles, observational study cases 2 articles, among which fifteen articles were proved to be high quality (according to Jadad scoring system, five score 4, six score 5, four score 7, two chapters were judged to be low quality scoring 3. Finally, we summerize that: 1 The first choice of treatment for acute relapses is glucocorticoids and we suggest that plasmapheresis or intravenous immunoglobulin may be tried as an alternative therapy in acute MS relapse, especially in case of contraindications to intravenous methylprednisolone. 2 Immunomodulatory or immunosuppressive treatment (IFN-β, glatiramer acetate, mitoxantrone, natalizumab can be an option to prevent new relapses and progression of disability. 3 Fingolimod is an oral treatment for multiple sclerosis to improve treatment adherence. Conclusion Using evidence-based medicine methods can provide us best clinical evidence on MS treatment.

    Adoptive cell therapy (ACT) has been developed in cancer treatment by transferring/infusing immune cells into cancer patients, which are able to recognize, target, and destroy tumor cells. Recently, sipuleucel-T and genetically-modified T cells expressing chimeric antigen receptors (CAR) show a great potential to control metastatic castration-resistant prostate cancer and hematologic malignancies in clinic. This review summarized some of the major evidence-based ACT and the challenges to improve cell quality and reduce the side effects in the field. This review also provided future research directions to make sure ACT widely available in clinic.

    This work aims to deepen our understanding of the role played by technical guidelines and tools for the design, construction and operation of healthcare facilities, ultimately establishing the impact of the physical environment on staff and patient outcomes. Using case studies largely drawn from the UK, Europe, China and Australasia, design approaches such as sustainability (e.g. targets for energy efficiency, carbon neutrality, reduction of waste), evidence-based design (EBD), and Post-Project Evaluation (PPE) are examined in order to identify policies, mechanisms and strategies that can promote an integrated learning environment that in turn supports innovation in healthcare.

    Recommended strategies for developing evidence-based clinical practice guidelines (CPGs) are provided. The intent is that future CPGs developed with the support of the Section on Pediatrics of the American Physical Therapy Association would consistently follow similar developmental processes to yield consistent quality and presentation. Steps in the process of developing CPGs are outlined and resources are provided to assist CPG developers in carrying out their task. These recommended processes may also be useful to CPG developers representing organizations with similar structures, objectives, and resources.

    Fish and aquatic invertebrates deserve evidence-based medicine. Pharmacologic information is available; most pharmacokinetic studies are derived from the aquaculture industry and extrapolated to ornamental fish. Conversely, advanced diagnostics and information regarding diseases affecting only ornamental fish and invertebrates require more peer-reviewed experimental studies; the examples of carp edema virus, sea star wasting disease, seahorse nutrition, and gas bubble disease of fish under human care are discussed. Antinociception is also a controversial topic of growing interest in aquatic animal medicine. This article summarizes information regarding new topics of interest in companion fish and invertebrates and highlights some future avenues for research. Copyright © 2017 Elsevier Inc.
