We have developed a specific language for the representation of Clinical Practice Guidelines (CPGs) and Windows C++ and platform independent JAVA applications for multimedia presentation and edition of electronically stored CPGs. This approach facilitates translation of guidelines and protocols from paper to computer-based flowchart representations. Users can navigate through the algorithm with a friendly user interface and access related multimedia information within the context of each clinical problem. CPGs can be stored in a computer server and distributed over the World Wide Web, facilitating dissemination, local adaptation, and use as a reference element in medical care. We have chosen the Agency for Health Care and Policy Research's heart failure guideline to demonstrate the capabilities of our tool.

Speech pathologists’ experiences with stroke clinical practice guidelines and the barriers and facilitators influencing their use: a national descriptive study

PubMed Central

2014-01-01

Background Communication and swallowing disorders are a common consequence of stroke. Clinical practice guidelines (CPGs) have been created to assist health professionals to put research evidence into clinical practice and can improve stroke care outcomes. However, CPGs are often not successfully implemented in clinical practice and research is needed to explore the factors that influence speech pathologists’ implementation of stroke CPGs. This study aimed to describe speech pathologists’ experiences and current use of guidelines, and to identify what factors influence speech pathologists’ implementation of stroke CPGs. Methods Speech pathologists working in stroke rehabilitation who had used a stroke CPG were invited to complete a 39-item online survey. Content analysis and descriptive and inferential statistics were used to analyse the data. Results 320 participants from all states and territories of Australia were surveyed. Almost all speech pathologists had used a stroke CPG and had found the guideline “somewhat useful” or “very useful”. Factors that speech pathologists perceived influenced CPG implementation included the: (a) guideline itself, (b) work environment, (c) aspects related to the speech pathologist themselves, (d) patient characteristics, and (e) types of implementation strategies provided. Conclusions There are many different factors that can influence speech pathologists’ implementation of CPGs. The factors that influenced the implementation of CPGs can be understood in terms of knowledge creation and implementation frameworks. Speech pathologists should continue to adapt the stroke CPG to their local work environment and evaluate their use. To enhance guideline implementation, they may benefit from a combination of educational meetings and resources, outreach visits, support from senior colleagues, and audit and feedback strategies.

Initiatives to raise the quality of care provided to mothers need to be given priority in Sub Saharan Africa (SSA). The promotion of clinical practice guidelines (CPGs) is a common strategy, but their implementation is often challenging, limiting their potential impact. Through a cross-country perspective, this study explored CPGs for maternal health in Burkina Faso, Ghana, and Tanzania. The objectives were to compare factors related to CPG use including their content compared with World Health Organization (WHO) guidelines, their format, and their development processes. Perceptions of their availability and use in practice were also explored. The overall purpose was to further the understanding of how to increase CPGs' potential to improve quality of care for mothers in SSA. The study was a multiple case study design consisting of cross-country comparisons using document review and key informant interviews. A conceptual framework to aid analysis and discussion of results was developed, including selected domains related to guidelines' implementability and use by health workers in practice in terms of usability, applicability, and adaptability. The study revealed few significant differences in content between the national guidelines for maternal health and WHO recommendations. There were, however, marked variations in the format of CPGs between the three countries. Apart from the Ghanaian and one of the Tanzanian CPGs, the levels of both usability and applicability were assessed as low or medium. In all three countries, the use of CPGs by health workers in practice was perceived to be limited. Our cross-country study suggests that it is not poor quality of content or lack of evidence base that constitute the major barrier for CPGs to positively impact on quality improvement in maternal care in SSA. It rather emphasises the need to prioritise the format of guidelines to increase their usability and applicability and to consider these attributes together with implementation strategies as integral to their development processes.

Clinical practice guidelines (CPGs) have been shown to improve processes of care and health outcomes, but there is often a discrepancy between recommendations for care and clinical practice. This study sought to explore general practitioner (GP) attitudes towards CPGs, in general and specifically for osteoarthritis (OA), with the implications for translating OA care into practice. A self-administered questionnaire was conducted in January 2013 with a sample of 228 GPs in New South Wales and South Australia. Seventy-nine GPs returned questionnaires (response rate 35%). Nearly all GPs considered that CPGs support decision-making in practice (94%) and medical education (92%). Very few respondents regarded CPGs as a threat to clinical autonomy, and most recognised that individual patient circumstances must be taken into account. Shorter CPG formats were preferred over longer and more comprehensive formats, with preferences being evenly divided among respondents for short, 2-3-page summaries, flowcharts or algorithms and single page checklists. GPs considered accessibility to CPGs to be important, and electronic formats were popular. Familiarity and use of The Royal Australian College of General Practitioners OA Guideline was poor, with most respondents either not aware of it (30%; 95% confidence interval (CI) 27 - 41%), had never used it (19%; 95% CI 12 - 29%) or rarely used it (34%; 95% CI 25-45%). If CPGs are to assist with the translation of evidence into practice, they must be easily accessible and in a format that encourages use.

The use of clinical practice guidelines (CPGs), particularly the routine implementation of evidence-based cardiovascular health maintenance and disease management recommendations, affords both expert and nonexpert practitioners the opportunity to achieve better, and at least theoretically similar, patient outcomes. However, health care practitioners are often stymied in their efforts to follow even well-researched and well-written CPGs as a consequence of contradictory information. The purposeful integration and harmonization of Canadian cardiovascular CPGs, regardless of their specific risk factor or clinical management focus, is critical to their widespread acceptance and implementation. This level of cooperation and coordination among CPG groups and organizations would help to ensure that their clinical practice roadmaps (ie, best practice recommendations) contain clear, concise and complementary, rather than contradictory, patient care information. Similarly, the application of specific tools intended to improve the quality of CPGs, such as the Appraisal of Guidelines for Research and Evaluation (AGREE) assessment tool, may also lead to improvements in CPG quality and potentially enhance their acceptance and implementation.

By November 2013, a total of 125 clinical practice guidelines (CPGs) have been developed in Korea. However, despite the high burden of diseases and the clinical importance of CPGs, most chronic diseases do not have available CPGs. Merely 83 CPGs are related to chronic diseases, and only 40 guidelines had been developed in the last 5 yr. Considering the rate of the production of new evidence in medicine and the worsening burden from chronic diseases, the need for developing CPGs for more chronic diseases is becoming increasingly pressing. Since 2011, the Korean Academy of Medical Sciences and the Korea Centers for Disease Control and Prevention have been jointly developing CPGs for chronic diseases. However, priorities have to be set and resources need to be allocated within the constraint of a limited funding. This study identifies the chronic diseases that should be prioritized for the development of CPGs in Korea. Through an objective assessment by using the analytic hierarchy process and a subjective assessment with a survey of expert opinion, high priorities were placed on ischemic heart disease, cerebrovascular diseases, Alzheimer's disease and other dementias, osteoarthritis, neck pain, chronic kidney disease, and cirrhosis of the liver.

Whilst Clinical Practice Guidelines (CPGs) are used for the development of local protocols in kidney transplantation (Ktx), the quality of their methodology is variable. This systematic review aimed to critically appraise international CPGs in all aspects of Ktx using the Appraisal of Guidelines for Research and Evaluation (AGREE) II tool. CPGs in Ktx and donation published between 2010 and 2017 were identified from MEDLINE, Embase, National Guideline Clearinghouse, NHS and NICE Evidence Searches, and the websites of transplant societies. Using AGREE II, 3 appraisers assessed the quality of CPGs. Interrater reliability was measured using the intraclass correlation coefficient (ICC). Searches identified 3,168 records and 115 CPGs were included. The highest scoring AGREE II domain was 'Scope and Purpose' (80%; Range 30-100%), followed by 'Clarity of Presentation' (77%; Range 43-98%), 'Editorial independence' (52%; Range 0-94%), 'Rigour of Development' (47%; Range 6-97%) and 'Stakeholder Involvement' (41%; Range 11-85%). The poorest scoring domain was 'Applicability' (31%; Range 3-74%). Most CPGs were recommended for future use either with (63%) or without modifications (18%). A small number were not recommended for future use (14%) or reviewers did not agree on recommending the CPG (5%). The overall mean CPG quality score was 4 out of 7 (Range 2-7). The mean ICC of 0.74 indicated substantial agreement between reviewers. The quality of international CPGs in Ktx was variable, and most CPGs lacked key aspects of methodological robustness and transparency. Improvements in methodology, patient involvement and strategies for implementation are required.

Clinical practice guidelines (CPGs) have been developed to summarize evidence about the management of rheumatoid arthritis (RA) and facilitate the uptake of evidence-based knowledge by consumers, health professionals, health administrators and policy makers. The objectives of this review was to assess the quality of CPGS on non-pharmacological management of RA with a standardized and validated instrument--the Appraisal of Guidelines for Research and Evaluation (AGREE II) tool and summarize the key recommendations from these CPGs. Scientific literature databases from 2001 to 2013 were systematically searched and a total of 13 CPGs for RA was identified. Only a minority of AGREE II domains were effectively addressed by the CPGS. Scope and purpose was effectively addressed in 10 out of 13 CPGs, stakeholder involvement in 11 CPGs, rigor of development in 6 CPGs, clarity/presentation in 9 CPGs, editorial independence in 1 CPGs, and applicability in none of the CPGs. The overall quality of the included CPGs according to the 7-point AGREE II scoring system was 4.8 ± 1.04. Patient education/self-management, aerobic, dynamic and stretching exercises were the commonly recommended for the non-pharmacological management of RA by the high-quality CPGs. The general clinical management recommendations tended to be similar among high-quality CPGs. Non-pharmacological management interventions were superficially addressed in more than half of the selected CPGs. CPGs creators should use the AGREE II criteria when developing guidelines. Innovative and effective methods of CPGs implementation to users are needed to ultimately enhance the quality of life of arthritic individuals. In addition, it was difficult to establish between strongly recommended, recommended and weakly recommended, as there is no consensus between the strength of the recommendations between the appraised CPGs.

Evidence-based clinical practice guidelines (CPGs) are defined as "statements that are scientifically reviewed about evidence and systematically developed to assist in the doctors' and patients' decision making in certain clinical situations." This recommendation aims to promote good clinical practice for the provision of safe and effective practices of conscious sedation in dentistry. The development of this clinical practice guideline was conducted by performing a systematic search of the literature for evidence-based CPGs. Existing guidelines, relevant systematic reviews, policy documents, legislation, or other recommendations were reviewed and appraised. To supplement this information, key questions were formulated by the Guideline Development Group and used as the basis for designing systematic literature search strategies to identify literature that may address these questions. Guideline documents were evaluated through a review of domestic and international databases for the development of a renewing of existing conscious sedation guidelines for dentistry. Clinical practice guidelines were critically appraised for their methodologies using Appraisal of guidelines for research and evaluation (AGREE) II. A total of 12 existing CPGs were included and 13 recommendations were made in a range of general, adult, and pediatric areas. The clinical practice guidelines for conscious sedation will be reviewed in 5 years' time for further updates to reflect significant changes in the field.

Support of personalized medicine through risk-stratified treatment recommendations - an environmental scan of clinical practice guidelines

PubMed Central

2013-01-01

Background Risk-stratified treatment recommendations facilitate treatment decision-making that balances patient-specific risks and preferences. It is unclear if and how such recommendations are developed in clinical practice guidelines (CPGs). Our aim was to assess if and how CPGs develop risk-stratified treatment recommendations for the prevention or treatment of common chronic diseases. Methods We searched the United States National Guideline Clearinghouse for US, Canadian and National Institute for Health and Clinical Excellence (United Kingdom) CPGs for heart disease, stroke, cancer, chronic obstructive pulmonary disease and diabetes that make risk-stratified treatment recommendations. We included only those CPGs that made risk-stratified treatment recommendations based on risk assessment tools. Two reviewers independently identified CPGs and extracted information on recommended risk assessment tools; type of evidence about treatment benefits and harms; methods for linking risk estimates to treatment evidence and for developing treatment thresholds; and consideration of patient preferences. Results We identified 20 CPGs that made risk-stratified treatment recommendations out of 133 CPGs that made any type of treatment recommendations for the chronic diseases considered in this study. Of the included 20 CPGs, 16 (80%) used evidence about treatment benefits from randomized controlled trials, meta-analyses or other guidelines, and the source of evidence was unclear in the remaining four (20%) CPGs. Nine CPGs (45%) used evidence on harms from randomized controlled trials or observational studies, while 11 CPGs (55%) did not clearly refer to harms. Nine CPGs (45%) explained how risk prediction and evidence about treatments effects were linked (for example, applying estimates of relative risk reductions to absolute risks), but only one CPG (5%) assessed benefit and harm quantitatively and three CPGs (15%) explicitly reported consideration of patient preferences. Conclusions Only a small proportion of CPGs for chronic diseases make risk-stratified treatment recommendations with a focus on heart disease and stroke prevention, diabetes and breast cancer. For most CPGs it is unclear how risk-stratified treatment recommendations were developed. As a consequence, it is uncertain if CPGs support patients and physicians in finding an acceptable benefit- harm balance that reflects both profile-specific outcome risks and preferences.

Clinical practice guidelines (CPGs) are systematically developed statements to assist practitioner and patient decisions about appropriate healthcare for specific clinical circumstances. There is a limited number of studies on guidelines in Turkey. The quality of Ministry of Health guidelines have formerly been assessed whereas there is no information on the other guidelines developed in the country. This study aims to assess the quality of CPGs that are developed by professional societies that work for the health sector in Turkey, and compare the findings with international guidelines. Professional societies that work for the health sector were determined by using the data obtained from the Ministry of Internal Affairs. Inclusion and exclusion criteria were defined for selecting the CPGs. Guidelines containing recommendations about disease management to the doctors, accessible online, developed within the past 5 years, citing references for recommendations, about the diseases over 1% prevalence according to the "Statistical Yearbook of Turkey 2012" were included in the study. The quality of CPGs were assessed with the AGREE II instrument, which is an internationally recognized tool for this purpose. Four independent reviewers, who did not participate in the development of the selected guidelines and were trained in CPG appraisal, used the AGREE instrument for assessment of the selected guidelines. 47 professional societies were defined which provided access to CPGs in their websites; 3 of them were only open to members so these could not be reached. 8 CPGs from 7 societies were selected from a total of 401 CPGs from 44 societies. The mean scores of the domains of the guidelines which were assessed by the AGREE II tool were; 64%, stakeholder involvement: 37.9%, rigour of development: 35.3%, clarity and presentation: 77.9%, applicability: 49.0% and editorial independence: 46.0%. This is the first study in Turkey regarding quality appraisal of guidelines developed by the local professional societies. It adds to the limited amount of information in the literature that comes from Turkey as well as other developing countries.

The aims of this study were to investigate whether there is a gap between evidence of traditional medicine (TM) interventions in East-Asian countries from the current Clinical Practice Guidelines (CPGs) and evidence from current systematic reviews and meta-analyses (SR-MAs) and to analyze the impact of this gap on present CPGs. We examined 5 representative TM interventions in the health care systems of East-Asian countries. We searched seven relevant databases for CPGs to identify whether core CPGs included evidence of TM interventions, and we searched 11 databases for SR-MAs to re-evaluate current evidence on TM interventions. We then compared the gap between the evidence from CPGs and SR-MAs. Thirteen CPGs and 22 SR-MAs met our inclusion criteria. Of the 13 CPGs, 7 CPGs (54%) mentioned TM interventions, and all were for acupuncture (only one was for both acupuncture and acupressure). However, the CPGs did not recommend acupuncture (or acupressure). Of 22 SR-MAs, 16 were for acupuncture, 5 for manual therapy, 1 for cupping, and none for moxibustion and herbal medicine. Comparing the evidence from CPGs and SR-MAs, an underestimation or omission of evidence for acupuncture, cupping, and manual therapy in current CPGs was detected. Thus, applying the results from the SR-MAs, we moderately recommend acupuncture for chronic LBP, but we inconclusively recommend acupuncture for (sub)acute LBP due to the limited current evidence. Furthermore, we weakly recommend cupping and manual therapy for both (sub)acute and chronic LBP. We cannot provide recommendations for moxibustion and herbal medicine due to a lack of evidence. The current CPGs did not fully reflect the evidence for TM interventions. As relevant studies such as SR-MAs are conducted and evidence increases, the current evidence on acupuncture, cupping, and manual therapy should be rigorously considered in the process of developing or updating the CPG system.

Fertility preservation care for children, adolescents, and young adults (CAYAs) with cancer is not uniform among practitioners. To ensure high-quality care, evidence-based clinical practice guidelines (CPGs) are essential. The authors identified existing CPGs for fertility preservation in CAYAs with cancer, evaluated their quality, and explored differences in recommendations. A systematic search in PubMed (January 2000-October 2014); guideline databases; and Web sites of oncology, pediatric, and fertility organizations was performed. Two reviewers evaluated the quality of the identified CPGs using the Appraisal of Guidelines for Research and Evaluation II Instrument (AGREE II). From high-quality CPGs, the authors evaluated concordant and discordant areas among the recommendations. A total of 25 CPGs regarding fertility preservation were identified. The average AGREE II domain scores (scale of 0%-100%) varied from 15% on applicability to 100% on clarity of presentation. The authors considered 8 CPGs (32%) to be of high quality, which was defined as scores ≥60% in any 4 domains. Large variations in the recommendations of the high-quality CPGs were observed, with 87.2% and 88.6%, respectively, of discordant guideline areas among the fertility preservation recommendations for female and male patients with cancer. Only approximately one-third of the identified CPGs were found to be of sufficient quality. Of these CPGs, the fertility preservation recommendations varied substantially, which can be a reflection of inadequate evidence for specific recommendations, thereby hindering the ability of providers to deliver high-quality care. CPGs including a transparent decision process for fertility preservation can help health care providers to deliver optimal and uniform care, thus improving the quality of life of CAYAs with cancer and cancer survivors.

Ferreira de Meneses, Sarah; Rannou, Francois; Hunter, David J

2016-06-01

Osteoarthritis (OA) is a leading cause of disability worldwide. Clinical practice guidelines (CPGs) have been developed to facilitate improved OA management. Scientific communities worldwide have proposed CPGs for OA treatment. Despite the number of highly prominent guidelines available and their remarkable consistency, their uptake has been suboptimal. Possibly because of the multitude of barriers related to the implementation of CPGs. For example, different guidelines show contradictions, some lack evidence, and they lack a hierarchy or tools to facilitate their translation and application. Also, the guidelines do not acknowledge the effect of comorbidities on choosing the treatments. Finally, poor integration of multidisciplinary services within and across healthcare settings is a major barrier to the effective implementation of management guidelines. Here we describe the main problems related to the OA guidelines and some solutions so as to offer some guidance on the elaboration of future CPGs and their implementation in primary care.

The concept of evidence-based medicine has evolved over the past 2 decades, and has become a cornerstone to clinical decision-making in virtually every aspect of medicine. With a commitment to providing its members with high-quality evidence-based guidelines, the American Academy of Orthopaedic Surgeons has instituted concerted efforts since 2006 to develop clinical practice guidelines (CPGs) and appropriate use criteria (AUCs) for certain orthopaedic conditions. Many of these CPGs and AUCs detail the management of pediatric orthopaedic conditions. By the same token, members of the Pediatric Orthopaedic Society of North America (POSNA) Evidence Based Practice Committee have been publishing succinct evaluations of randomized controlled trials in pediatric orthopaedic surgery to create an evidence-based repository for quick reference to available high-level evidence as well as resource to identify gaps in the current research and identify opportunities for future investigation. In instances where higher-level evidence needed to develop CPGs is not available to address a critically important clinical question, consensus recommendations from experts in the field have been obtained to develop best practice guidelines (BPGs). The purpose of this review is to provide readers with a deeper understanding of the key principles of evidence-based medicine and methodologies used for the development of CPGs, AUCs, and BPGs.

With efforts to combat opioid use disorder, there is an increased interest in clinical practice guidelines (CPGs) for opioid use disorder treatments. No literature exists examining the quality of systematic reviews used in opioid use disorder CPGs. This study aims to describe the methodological quality and reporting clarity of systematic reviews (SRs) used to create CPGs for opioid use disorder. From June to July 2016 guideline clearinghouses and medical literature databases were searched for relevant CPGs used in the treatment of opioid use disorder. Included CPGs must have been recognized by a national organization. SRs from the reference section of each CPG was scored by using AMSTAR (a measurement tool to assess the methodological quality of systematic reviews) tool and PRISMA (preferred reporting items for systematic reviews and meta-analyses) checklist. Seventeen CPGs from 2006-2016 were included in the review. From these, 57 unique SRs were extracted. SRS comprised 0.28% to 17.92% of all references found in the CPGs. All SRs obtained moderate or high methodological quality score on the AMSTAR tool. All reviews met at least 70% of PRISMA criteria. In PRISMA, underperforming areas included accurate title labeling, protocol registration, and risk of bias. Underperforming areas in AMSTAR included conflicts of interest, funding, and publication bias. A positive correlation was found between AMSTAR and PRISMA scores (r = .79). Although the SRs in the CPGs were of good quality, there are still areas for improvement. Systematic reviewers should consult PRISMA and AMSTAR when conducting and reporting reviews. It is important for CPG developers to consider methodological quality as a factor when developing CPG recommendations, recognizing that the quality of systematic reviews underpinning guidelines does not necessarily correspond to the quality of the guideline itself.

Objective To develop and encourage the adoption of clinical practice guidelines (CPGs) for smoking cessation in Canada by engaging stakeholders in the adaptation of existing high-quality CPGs using principles of the ADAPTE framework. Methods An independent expert body in guideline review conducted a review and identified six existing CPGs, which met a priori criteria for quality and potential applicability to the local context. Summary statements were extracted and assigned a grade of recommendation and level of evidence by a second expert panel. Regional knowledge exchange brokers recruited additional stakeholders to build a multidisciplinary network of over 800 clinicians, researchers and decision-makers from across Canada. This interprofessional network and other stakeholders were offered various opportunities to provide input on the guideline both online and in person. We actively encouraged end-user input into the development and adaptation of the guidelines to ensure applicability to various practice settings and to promote adoption. Results The final guideline contained 24 summary statements along with supporting clinical considerations, across six topic area sections. The guideline was adopted by various provincial/territorial and national government and non-governmental organisations. Conclusions This method can be applied in other jurisdictions to adapt existing high-quality smoking cessation CPGs to the local context and to facilitate subsequent adoption by various stakeholders.

The objective of this study was to assess the methodological quality and clarity of reporting of the systematic reviews (SRs) supporting clinical practice guideline (CPG) recommendations in the management of ST-elevation myocardial infarction (STEMI) across international CPGs. We searched 13 guideline clearinghouses including the National Guideline Clearinghouse and Guidelines International Network (GIN). To meet inclusion criteria CPGs must be pertinent to the management of STEMI, endorsed by a governing body or national organization, and written in English. We retrieved SRs from the reference sections using a combination of keywords and hand searching. Two investigators scored eligible SRs using AMSTAR and PRISMA. We included four CPGs. We extracted 71 unique SRs. These SRs received AMSTAR scores ranging from 1 (low) to 9 (high) on an 11-point scale. All CPGs consistently underperformed in areas including disclosure of funding sources, risk of bias, and publication bias according to AMSTAR. PRISMA checklist completeness ranged from 44% to 96%. The PRISMA scores indicated that SRs did not provide a full search strategy, study protocol and registration, assessment of publication bias or report funding sources. Only one SR was referenced in all four CPGs. All CPGs omitted a large subset of available SRs cited by other guidelines. Our study demonstrates the variable quality of SRs used to establish recommendations within guidelines included in our sample. Although guideline developers have acknowledged this variability, it remains a significant finding that needs to be addressed further. This research did not receive any specific grant from funding agencies in the public, commercial, or not-for-profit sectors. Copyright © 2017 Elsevier Inc. All rights reserved.

There has been a significant increase in the publication of clinical practice guidelines (CPGs) for respiratory diseases in China. However, little is known about the quality and potential impacts of these CPGs. Our objective was to critically evaluate the quality of Chinese CPGs for respiratory diseases that were published in peer-reviewed medical journals. A systematic search of scientific literature published between 1979 and 2013 was undertaken to identify and select CPGs that were related to respiratory diseases. Four Chinese databases (the Chinese Biomedical Literature database [CBM], the China National Knowledge Infrastructure [CNKI], the VIP database, and the WANFANG database) were used. The quality of eligible guidelines was assessed independently by four reviewers using the Appraisal of Guidelines for Research and Evaluation (AGREE) II instrument. The overall agreement among reviewers was evaluated using an intraclass correlation coefficient. A total of 109 guidelines published in 27 medical journals from 1979 to 2013 were evaluated. The overall agreement among reviewers was considered good (intraclass correlation coefficient, 0.838; 95% CI, 0.812-0.862). The scores of the six AGREE domains were low: 57.3% for scope and purpose (range, 4.2%-80.5%), 23.8% for stakeholder involvement (range, 2.8%-54.2%), 7.7% for rigor of development (range, 0%-27.1%), 59.8% for clarity and presentation (range, 22.2%-80.6%), 10.9% for applicability (range, 0%-22.9%), and 0.6% for editorial independence (range, 0%-16.7%). Scores for all guidelines were below 60%, and only three guidelines (2.8%) were recommended for clinical practice with modifications. The quality of the guidelines was low, and stakeholder involvement, rigor of development, applicability, and editorial independence should be considered in the future development of CPGs for respiratory diseases in China.

Background Clinical practice guidelines (CPGs) are systematically developed statements to assist practitioner and patient decisions about appropriate healthcare for specific clinical circumstances. There is a limited number of studies on guidelines in Turkey. The quality of Ministry of Health guidelines have formerly been assessed whereas there is no information on the other guidelines developed in the country. Aim This study aims to assess the quality of CPGs that are developed by professional societies that work for the health sector in Turkey, and compare the findings with international guidelines. Methodology Professional societies that work for the health sector were determined by using the data obtained from the Ministry of Internal Affairs. Inclusion and exclusion criteria were defined for selecting the CPGs. Guidelines containing recommendations about disease management to the doctors, accessible online, developed within the past 5 years, citing references for recommendations, about the diseases over 1% prevalence according to the “Statistical Yearbook of Turkey 2012” were included in the study. The quality of CPGs were assessed with the AGREE II instrument, which is an internationally recognized tool for this purpose. Four independent reviewers, who did not participate in the development of the selected guidelines and were trained in CPG appraisal, used the AGREE instrument for assessment of the selected guidelines. Findings 47 professional societies were defined which provided access to CPGs in their websites; 3 of them were only open to members so these could not be reached. 8 CPGs from 7 societies were selected from a total of 401 CPGs from 44 societies. The mean scores of the domains of the guidelines which were assessed by the AGREE II tool were; Scope and purpose: 64%, stakeholder involvement: 37.9%, rigour of development: 35.3%, clarity and presentation: 77.9%, applicability: 49.0% and editorial independence: 46.0%. Conclusion This is the first study in Turkey regarding quality appraisal of guidelines developed by the local professional societies. It adds to the limited amount of information in the literature that comes from Turkey as well as other developing countries. PMID:27295303

Reconciling pairs of concurrently used clinical practice guidelines using Constraint Logic Programming.

2011-01-01

This paper describes a new methodological approach to reconciling adverse and contradictory activities (called points of contention) occurring when a patient is managed according to two or more concurrently used clinical practice guidelines (CPGs). The need to address these inconsistencies occurs when a patient with more than one disease, each of which is a comorbid condition, has to be managed according to different treatment regimens. We propose an automatic procedure that constructs a mathematical guideline model using the Constraint Logic Programming (CLP) methodology, uses this model to identify and mitigate encountered points of contention, and revises the considered CPGs accordingly. The proposed procedure is used as an alerting mechanism and coupled with a guideline execution engine warns the physician about potential problems with the concurrent application of two or more guidelines. We illustrate the operation of our procedure in a clinical scenario describing simultaneous use of CPGs for duodenal ulcer and transient ischemic attack.

Overlap in drug-disease associations between clinical practice guidelines and drug structured product label indications.

Clinical practice guidelines (CPGs) recommend pharmacologic treatments for clinical conditions, and drug structured product labels (SPLs) summarize approved treatment indications. Both resources are intended to promote evidence-based medical practices and guide clinicians' prescribing decisions. However, it is unclear how well CPG recommendations about pharmacologic therapies match SPL indications for recommended drugs. In this study, we perform text mining of CPG summaries to examine drug-disease associations in CPG recommendations and in SPL treatment indications for 15 common chronic conditions. We constructed an initial text corpus of guideline summaries from the National Guideline Clearinghouse (NGC) from a set of manually selected ICD-9 codes for each of the 15 conditions. We obtained 377 relevant guideline summaries and their Major Recommendations section, which excludes guidelines for pediatric patients, pregnant or breastfeeding women, or for medical diagnoses not meeting inclusion criteria. A vocabulary of drug terms was derived from five medical taxonomies. We used named entity recognition, in combination with dictionary-based and ontology-based methods, to identify drug term occurrences in the text corpus and construct drug-disease associations. The ATC (Anatomical Therapeutic Chemical Classification) was utilized to perform drug name and drug class matching to construct the drug-disease associations from CPGs. We then obtained drug-disease associations from SPLs using conditions mentioned in their Indications section in SIDER. The primary outcomes were the frequency of drug-disease associations in CPGs and SPLs, and the frequency of overlap between the two sets of drug-disease associations, with and without using taxonomic information from ATC. Without taxonomic information, we identified 1444 drug-disease associations across CPGs and SPLs for 15 common chronic conditions. Of these, 195 drug-disease associations overlapped between CPGs and SPLs, 917 associations occurred in CPGs only and 332 associations occurred in SPLs only. With taxonomic information, 859 unique drug-disease associations were identified, of which 152 of these drug-disease associations overlapped between CPGs and SPLs, 541 associations occurred in CPGs only, and 166 associations occurred in SPLs only. Our results suggest that CPG-recommended pharmacologic therapies and SPL indications do not overlap frequently when identifying drug-disease associations using named entity recognition, although incorporating taxonomic relationships between drug names and drug classes into the approach improves the overlap. This has important implications in practice because conflicting or inconsistent evidence may complicate clinical decision making and implementation or measurement of best practices.

To assess the quality of integrative medicine clinical practice guidelines (CPGs) published before 2014. A systematic search of the scientific literature published before 2014 was conducted to select integrative medicine CPGs. Four major Chinese integrated databases and one guideline database were searched: the Chinese Biomedical Literature Database (CBM), the China National Knowledge Infrastructure (CNKI), China Science and Technology Journal Database (VIP), Wanfang Data, and the China Guideline Clearinghouse (CGC). Four reviewers independently assessed the quality of the included guidelines using the Appraisal of Guidelines for Research and Evaluation (AGREE) II Instrument. Overall consensus among the reviewers was assessed using the intra-class correlation coefficient (ICC). A total of 41 guidelines published from 2003 to 2014 were included. The overall consensus among the reviewers was good [ICC: 0.928; 95% confifi dence interval (CI): 0.920 to 0.935]. The scores on the 6 AGREE domains were: 17% for scope and purpose (range: 6% to 32%), 11% for stakeholder involvement (range: 0 to 24%), 10% for rigor of development (range: 3% to 22%), 39% for clarity and presentation (range: 25% to 64%), 11% for applicability (range: 4% to 24%), and 1% for editorial independence (range: 0 to 15%). The quality of integrative medicine CPGs was low, the development of integrative medicine CPGs should be guided by systematic methodology. More emphasis should be placed on multi-disciplinary guideline development groups, quality of evidence, management of funding and conflfl icts of interest, and guideline updates in the process of developing integrative medicine CPGs in China.

Clinical practice guidelines (CPGs) are typically written for health care professionals but are meant to assist patients with health care decisions. A number of guideline producers have started to develop patient versions of CPGs to reach this audience. To describe the content and purpose of patient versions of CPGs and compare with patient and public views of CPGs. A descriptive qualitative study with a directed content analysis of a sample of patient versions of CPGs published and freely available in English from 2012 to 2014. We included 34 patient versions of CPGs from 17 guideline producers. Over half of the patient versions were in dedicated patient sections of national/professional agency websites. There was essentially no information about how to manage care in the health care system. The most common purpose was to equip people with information about disease, tests or treatments, and recommendations, but few provided quantitative data about benefits and harms of treatments. Information about beliefs, values and preferences, accessibility, costs, or feasibility of the interventions was rarely addressed. Few provided personal stories or scenarios to personalize the information. Three versions described the strength of the recommendation or the level of evidence. Our search for key institutions that produce patient versions of guidelines was comprehensive, but we only included English and freely available versions. Future work will include other languages. This review describes the current landscape of patient versions of CPGs and suggests that these versions may not address the needs of their targeted audience. Research is needed about how to personalize information, provide information about factors contributing to the recommendations, and provide access. © The Author(s) 2016.

Despite advancements in treating ruptured cerebral aneurysms, an aneurysmal subarachnoid hemorrhage (aSAH) is still a grave cerebrovascular disease associated with a high rate of morbidity and mortality. Based on the literature published to date, worldwide academic and governmental committees have developed clinical practice guidelines (CPGs) to propose standards for disease management in order to achieve the best treatment outcomes for aSAHs. In 2013, the Korean Society of Cerebrovascular Surgeons issued a Korean version of the CPGs for aSAHs. The group researched all articles and major foreign CPGs published in English until December 2015 using several search engines. Based on these articles, levels of evidence and grades of recommendations were determined by our society as well as by other related Quality Control Committees from neurointervention, neurology and rehabilitation medicine. The Korean version of the CPGs for aSAHs includes risk factors, diagnosis, initial management, medical and surgical management to prevent rebleeding, management of delayed cerebral ischemia and vasospasm, treatment of hydrocephalus, treatment of medical complications and early rehabilitation. The CPGs are not the absolute standard but are the present reference as the evidence is still incomplete, each environment of clinical practice is different, and there is a high probability of variation in the current recommendations. The CPGs will be useful in the fields of clinical practice and research. PMID:29526058

To adopt, to adapt, or to contextualise? The big question in clinical practice guideline development.

PubMed

Dizon, Janine Margarita; Machingaidze, Shingai; Grimmer, Karen

2016-09-13

Developing new clinical practice guidelines (CPGs) can be time-consuming and expensive. A more efficient approach could be to adopt, adapt or contextualise recommendations from existing good quality CPGs so that the resultant guidance is tailored to the local context. The first steps are to search for international CPGs that have a similar purpose, end-users and patients to your situation. The second step is to critically appraise the methodological quality of the CPGs to ensure that your guidance is based on credible evidence. Then the decisions begin. Can you simply 'adopt' this (parent) clinical practice guidelines, and implement the recommendations in their entirety, without any changes, in your setting? If so, then no further work is required. However this situation is rare. What is more likely, is that even if recommendations from the parent clinical practice guidelines can be adopted, how they are implemented needs to address local issues. Thus you may need to 'contextualise' the guidance, by addressing implementation issues such as local workforce, training, health systems, equipment and/or access to services. Generally this means that additional information is required (Practice/Context Points) to support effective implementation of the clinical practice guidelines recommendations. In some cases, you may need to 'adapt' the guidance, where you will make changes to the recommendations so that care is relevant to your local environments. This may involve additional work to search for local research, or obtain local consensus, regarding how best to adapt recommendations. For example, adaptation might reflect substituting one drug for another (drugs have similar effects, but the alternative drug to the recommended one may be cheaper, more easily obtained or more culturally acceptable). There is lack of standardisation of clinical practice guidelines terminology, leading clinical practice guideline activities often being poorly conceptualised or reported. We provide an approach that would help improve efficiency and standardisation of clinical practice guidelines activities.

How updating textual clinical practice guidelines impacts clinical decision support systems: a case study with bladder cancer management.

Guideline-based clinical decision support systems (CDSSs) can be effective in increasing physician compliance with recommendations. However, the ever growing pace at which medical knowledge is produced requires that clinical practice guidelines (CPGs) be updated regularly. It is therefore mandatory that CDSSs be revised accordingly. The French Association for Urology publishes CPGs on bladder cancer management every 2 years. We studied the impact of the 2004 revision of these guidelines, with respect to the 2002 version with a CDSS, UroDoc. We proposed a typology of knowledge base modifications resulting from the update of CPGs making the difference between practice, clinical conditions and recommendations refinement as opposed to new practice and new recommendations. The number of formalized recommendations increased from 577 in 2002 to 1,081 in 2004. We evaluated the two versions of UroDoc on a randomized sample of patient records. A single new practice that modifies a decision taken in 49% of all recorded decisions leads to a fall from 67% to 46% of the compliance rate of decisions.

Achieving 90% Adoption of Clinical Practice Guidelines Using the Delphi Consensus Method in a Large Orthopedic Group.

2016-11-01

Little is known about the implementation rate of clinical practice guidelines (CPGs). Our purpose was to report on the adoption rate of CPGs created and implemented by a large orthopedic group using the Delphi consensus method. The draft CPGs were created before the group's annual meeting by 5 teams each assigned a subset of topics. The draft guidelines included a statement and a summary of the available evidence. Each guideline was debated in both small-group and plenary sessions. Voting was anonymous and a 75% supermajority was required for passage. A Likert scale was used to survey the patient's experience with the process at 1 week, and the Kirkpatrick evaluation model was used to gauge the efficacy of the process over a 6-month time frame. Eighty-five orthopedic surgeons attended the meeting. Fifteen guidelines grouped into 5 topics were created. All passed. Eighty-six percent of attendees found the process effective and 84% felt that participating in the process made it more likely that they would adopt the guidelines. At 1 week, an average of 62% of attendees stated they were practicing the guideline as written (range: 35%-72%), and at 6 months, 96% stated they were practicing them (range: 82%-100%). We have demonstrated that a modified Delphi method for reaching consensus can be very effective in both creating CPGs and leading to their adoption. Further we have shown that the process is well received by participants and that an inclusionary approach can be highly successful. Copyright © 2016 Elsevier Inc. All rights reserved.

This systematic review critically evaluated clinical practice guidelines (CPGs) for treating adults with major depressive disorder, dysthymia, or subthreshold or minor depression for recommendations following inadequate response to first-line treatment with selective serotonin reuptake inhibitors (SSRIs). Searches for CPGs (January 2004 to November 2014) in English included 7 bibliographic databases and grey literature sources using CPG and depression as the keywords. Two raters selected CPGs on depression with a national scope. Data extraction included definitions of adequate response and recommended treatment options. Two raters assessed quality using the Appraisal of Guidelines for Research and Evaluation II (AGREE II) instrument. From 46,908 citations, 3167 were screened at full text. From these 21 CPG were applicable to adults in primary care and outpatient settings. Five CPGs consider patients with dysthymia or subthreshold or minor depression. None provides recommendations for those who do not respond to first-line SSRI treatment. For adults with MDD, most CPGs do not define an "inadequate response" or provide specific suggestions regarding how to choose alternative medications when switching to an alternative antidepressant. There is variability between CPGs in recommending combination strategies. AGREE II ratings for stakeholder involvement in CPG development, editorial independence, and rigor of development are domains in which depression guidelines are often less robust. About half of patients with depression require second-line treatment to achieve remission. Consistency and clarity in guidelines for second-line treatment of depression are therefore important for clinicians but lacking in most current guidelines. This may reflect a paucity of primary studies upon which to base conclusions.

Introduction: We provide an overview of the quality of recent clinical clinical practice guidelines (CPGs) for non-neurogenic male lower urinary tract symptoms (LUTS) and summarize the recommendations for their diagnosis, assessment, and treatment. Methods: We systematically searched recent (2008–2013) CPGs for non-neurogenic male LUTS. Eligible CPGs were assessed and appraised using Appraisal of Guidelines, Research and Evaluation II (AGREE II) tool by a CPG-appraisal group. The appraisal scores for each guideline were summarized according to each domain and in total. A recommendation summary was made across the guidelines for diagnostics, conservative management, medical, minimally invasive therapy, and surgical management. Results: A total of 8 guidelines were considered. According to AGREE II appraisal of guidelines, the National Institute for Health and Clinical Excellence (NICE), American Urological Association (AUA) and European Association of Urology (EAU) consistently scored high on the guideline domains assessed. Recommendations on diagnostics, conservative management, medical, and surgical management were consistent among the top 3 guidelines. However, we noted a discrepancy in recommending minimally invasive therapy as an alternative management of moderate to severe or bothersome non-neurogenic male LUTS secondary to benign prostatic enlargement (BPE); the NICE guideline, in particular, does not recommend using minimally invasive therapy. Conclusion: The quality of recent CPGs on non-neurogenic male LUTS was appraised and summarized. The guidelines from NICE, AUA and EAU were considered highly compliant to the AGREE II proposition for guideline formation and development. PMID:26279717

The objective was to provide an overview of the recommendations and quality of evidence-based clinical practice guidelines (CPGs) for the emergency management of mild traumatic brain injury (mTBI), with a view to informing best practice and improving the consistency of recommendations. Electronic searches of health databases (MEDLINE, EMBASE, The Cochrane Library, PsycINFO), CPG clearinghouse websites, CPG developer websites, and Internet search engines up to January 2010 were conducted. CPGs were included if 1) they were published in English and freely accessible, 2) their scope included the management of mTBI in the emergency department (ED), 3) the date of last search was within the past 10 years (2000 onward), 4) systematic methods were used to search for evidence, and 5) there was an explicit link between the recommendations and the supporting evidence. Four authors independently assessed the quality of the included CPGs using the Appraisal of Guidelines, Research and Evaluation (AGREE) Instrument. The authors extracted and categorized recommendations according to initial clinical assessment, imaging, management, observation, discharge planning, and patient information and follow-up. The search identified 18 potential CPGs, of which six met the inclusion criteria. The included CPGs varied in scope, target population, size, and guideline development processes. Four CPGs were assessed as "strongly recommended." The majority of CPGs did not provide information about the level of stakeholder involvement (mean AGREE standardized domain score = 57%, range = 25% to 81%), nor did they address the organizational/cost implications of applying the recommendations or provide criteria for monitoring and review of recommendations in practice (mean AGREE standardized domain score = 46.6%, range = 19% to 94%). Recommendations were mostly consistent in terms of the use of the Glasgow Coma Scale (GCS) score (adult and pediatric) to assess the level of consciousness, initial assessment criteria, the use of computed tomography (CT) scanning as imaging investigation of choice, and the provision of patient information. The CPGs defined mTBI in a variety of ways and described different rules to determine the need for CT scanning and therefore used different criteria to identify high-risk patients. Higher-quality CPGs for mTBI are consistent in their recommendations about assessment, imaging, and provision of patient information. There is not, however, an agreed definition of mTBI, and the quality of future CPGs could be improved with better reporting of stakeholder involvement, procedures for updating, and greater consideration of the applicability of the recommendations (cost implications, monitoring procedures). Nevertheless, guideline developers may benefit from adapting existing CPGs to their local context rather than investing in developing CPGs de novo. © 2011 by the Society for Academic Emergency Medicine.

Coupling computer-interpretable guidelines with a drug-database through a web-based system – The PRESGUID project

2004-01-01

Background Clinical Practice Guidelines (CPGs) available today are not extensively used due to lack of proper integration into clinical settings, knowledge-related information resources, and lack of decision support at the point of care in a particular clinical context. Objective The PRESGUID project (PREScription and GUIDelines) aims to improve the assistance provided by guidelines. The project proposes an online service enabling physicians to consult computerized CPGs linked to drug databases for easier integration into the healthcare process. Methods Computable CPGs are structured as decision trees and coded in XML format. Recommendations related to drug classes are tagged with ATC codes. We use a mapping module to enhance computerized guidelines coupling with a drug database, which contains detailed information about each usable specific medication. In this way, therapeutic recommendations are backed up with current and up-to-date information from the database. Results Two authoritative CPGs, originally diffused as static textual documents, have been implemented to validate the computerization process and to illustrate the usefulness of the resulting automated CPGs and their coupling with a drug database. We discuss the advantages of this approach for practitioners and the implications for both guideline developers and drug database providers. Other CPGs will be implemented and evaluated in real conditions by clinicians working in different health institutions. PMID:15053828

To explore perception, attitude, and satisfaction of paediatric clinicians, trainees, and nurses at King Khalid University Hospital towards clinical practice guidelines (CPGs) including the locally adapted diabetic ketoacidosis CPG (DKA-CPG). A cross-sectional survey was distributed to 260 doctors and nurses working in the paediatrics department. The response rate was 95.4%. The respondents had a positive perception and attitude towards general CPGs and specifically for the DKA-CPG; 98.7% thought CPGs were useful sources of advice, improved safety, and decreased risk, and reduced variation in practice. A total of 99.2% thought CPGs were good clinical tools, 98.3% satisfied with, had confidence in well-developed CPGs, and would recommend them to their colleagues to use, and 94.6% agreed they were cost-effective. The preferred format for CPGs was paper (46.6%) and electronic (42.9%). The DKA-CPG helped in managing patients and respondents were all satisfied and had confidence with it (100%). The rationale and objectives of the DKA-CPG were clear for 99.25%; 98.5% thought the layout was clear and well organized and user-friendly (96.2%). Compared with nurses, physicians had a higher perception towards CPGs in general (P < .05) and the DKA-CPG (P < .05). The paediatric doctors, and nurses have a great perception and satisfaction and positive attitude towards CPGs in general, towards the paediatric diabetic ketoacidosis CPG in particular, which in turn had a positive impact on the acceptability and implementation of the CPGs. These findings could help in sustaining a safe and high-quality health care environment through implementation of evidence-based CPGs. © 2018 John Wiley & Sons, Ltd.

A systematic review and quality appraisal of international guidelines for early breast cancer systemic therapy: Are recommendations sensitive to different global resources?

The breast cancer incidence in low and middle income countries (LMCs) is increasing globally, and patient outcomes are generally worse in these nations compared to high income countries (HICs). This is partly due to resource constraints associated with implementing recommended breast cancer therapies. Clinical practice guideline (CPG) adherence can improve breast cancer outcomes, however, many CPGs are created in HICs, and include costly recommendations that may not be feasible in LMCs. In addition, the quality of CPGs can be variable. The aim of this study was to perform a systematic review of CPGs on early breast cancer systemic therapy with potential international impact, to evaluate their content, quality, and resource sensitivity. A MEDLINE and gray literature search was completed for English language CPGs published between 2005 and 2010, and then updated to July 2014. Extracted guidelines were evaluated using the AGREE 2 instrument. Guidelines were specifically analyzed for resource sensitivity. Most of the extracted CPGs had similar recommendations with regards to systemic therapy. However, only one, the Breast Health Global Initiative, made recommendations with consideration of different global resources. Overall, the CPGs were of variable quality, and most scored poorly in the quality domain evaluating implementation barriers such as resources. Published CPGs for early breast cancer are created in HICs, have similar recommendations, and are generally resource-insensitive. Given the visibility and influence of these CPGs on LMCs, efforts to create higher quality, resource-sensitive guidelines with less redundancy are needed. Copyright © 2014 Elsevier Ltd.

This paper describes a new methodological approach to reconciling adverse and contradictory activities (called points of contention) occurring when a patient is managed according to two or more concurrently used clinical practice guidelines (CPGs). The need to address these inconsistencies occurs when a patient with more than one disease, each of which is a comorbid condition, has to be managed according to different treatment regimens. We propose an automatic procedure that constructs a mathematical guideline model using the Constraint Logic Programming (CLP) methodology, uses this model to identify and mitigate encountered points of contention, and revises the considered CPGs accordingly. The proposed procedure is used as an alerting mechanism and coupled with a guideline execution engine warns the physician about potential problems with the concurrent application of two or more guidelines. We illustrate the operation of our procedure in a clinical scenario describing simultaneous use of CPGs for duodenal ulcer and transient ischemic attack. PMID:22195153

Pit and fissure sealants are effective in reducing the incidence of occlusal caries, and multiple clinical practice guidelines (CPGs) have been developed for recommending their proper use. The usefulness of CPGs depends on their quality and on the rigour of the guideline development process. A study was made to assess the quality of current European CPGs based on the Appraisal of Guidelines for Research and Evaluation (AGREE II) instrument, which uses 23 key items rated on a 7-point scale to assess practice guideline development and the quality of reporting. A search was conducted for fissure sealant guidelines for preventing caries in children and adults at high and low risk published in the last 10 years. Calibration was carried out before scoring to assess agreement between the appraisers using the AGREE II instrument. The searches identified 19 relevant guidelines, and following application of the inclusion/exclusion criteria, three guidelines were retained for evaluation. The proportion of observed agreement was calculated, expressed by the agreement separately for positive and negative ratings (PA = 0.89, NA = 0-91). The results of the guideline assessments revealed the highest score for the Irish guideline, a moderate score for the French guideline and the lowest score for the European guideline. Based on the AGREE II instrument, the results obtained show significant variation in the quality assessment of the three European Fissure Sealant Guidelines. Future studies should be carried out both to develop quality dental CPGs and to investigate effective ways of adopting them. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

In Germany, physicians enrolled in disease management programs are legally obliged to follow evidence-based clinical practice guidelines. That is why a Program for National Disease Management Guidelines (German DM-CPG Program) was established in 2002 aiming at implementation of best-practice evidence-based recommendations for nationwide as well as regional disease management programs. Against this background the article reviews programs, methods and tools for implementing DM-CPGs via clinical pathways as well as regional guidelines for outpatient care. Special reference is given to the institutionalized program of adapting DM-CPGs for regional use by primary-care physicians in the State of Hesse.

Updating clinical practice guidelines (CPGs) is a crucial process for maintaining the validity of recommendations. Methodological handbooks should provide guidance on both developing and updating CPGs. However, little is known about the updating guidance provided by these handbooks. We conducted a systematic review to identify and describe the updating guidance provided by CPG methodological handbooks and included handbooks that provide updating guidance for CPGs. We searched in the Guidelines International Network library, US National Guidelines Clearinghouse and MEDLINE (PubMed) from 1966 to September 2013. Two authors independently selected the handbooks and extracted the data. We used descriptive statistics to analyze the extracted data and conducted a narrative synthesis. We included 35 handbooks. Most handbooks (97.1%) focus mainly on developing CPGs, including variable degrees of information about updating. Guidance on identifying new evidence and the methodology of assessing the need for an update is described in 11 (31.4%) and eight handbooks (22.8%), respectively. The period of time between two updates is described in 25 handbooks (71.4%), two to three years being the most frequent (40.0%). The majority of handbooks do not provide guidance for the literature search, evidence selection, assessment, synthesis, and external review of the updating process. Guidance for updating CPGs is poorly described in methodological handbooks. This guidance should be more rigorous and explicit. This could lead to a more optimal updating process, and, ultimately to valid trustworthy guidelines.

Objective To explore the complex issue of competing interests (CIs) in development of clinical practice guidelines (CPGs) in diabetes with stakeholders. Methods A multidisciplinary panel of 26 health, methodological, legal, and bioethical experts, trainees, and lay people from across Canada participated in a workshop on CIs in CPGs. Mixed methods were used such that qualitative themes were extracted from the discussions and quantitative survey data were collected. Results In the discussions, participants acknowledged that potential competing interests were not uncommon among sponsoring organizations and authors of CPGs. Avoidance of all potential CIs in development of CPGs was emulated as ideal, but considered probably unrealistic, given the paucity of peer-reviewed funding opportunities for development of evidence-informed CPGs and the scarcity of knowledgeable authors without CIs. An optimal approach for management of CIs in CPGs could not be agreed upon by participants. Full disclosure of any financial CIs for authors and sponsoring organizations as well as discouragement of external financial contributors from writing involvement, were endorsed by participants in the workshop and a subsequent survey. Conclusions Complete disclosure of financial CIs of sponsoring organizations and authors of CPGs is essential, yet the optimal approach to management of potential CIs is currently undefined.

Local tailoring of clinical practice guidelines (CPGs) requires experts in medicine and evidence synthesis unavailable in many practice settings. The authors' computer-based system enables developers and users to create, disseminate, and tailor CPGs, using normative decision models (DMs). ALCHEMIST, a web-based system, analyzes a DM, creates a CPG in the form of an annotated algorithm, and displays for the guideline user the optimal strategy. ALCHEMIST'S interface enables remote users to tailor the guideline by changing underlying input variables and observing the new annotated algorithm that is developed automatically. In a pilot evaluation of the system, a DM was used to evaluate strategies for staging non-small-cell lung cancer. Subjects (n = 15) compared the automatically created CPG with published guidelines for this staging and critiqued both using a previously developed instrument to rate the CPGs' usability, accountability, and accuracy on a scale of 0 (worst) to 2 (best), with higher scores reflecting higher quality. The mean overall score for the ALCHEMIST CPG was 1.502, compared with the published-CPG score of 0.987 (p = 0.002). The ALCHEMIST CPG scores for usability, accountability, and accuracy were 1.683, 1.393, and 1.430, respectively; the published CPG scores were 1.192, 0.941, and 0.830 (each comparison p < 0.05). On a scale of 1 (worst) to 5 (best), users' mean ratings of ALCHEMIST'S ease of use, usefulness of content, and presentation format were 4.76, 3.98, and 4.64, respectively. The results demonstrate the feasibility of a web-based system that automatically analyzes a DM and creates a CPG as an annotated algorithm, enabling remote users to develop site-specific CPGs. In the pilot evaluation, the ALCHEMIST guidelines met established criteria for quality and compared favorably with national CPGs. The high usability and usefulness ratings suggest that such systems can be a good tool for guideline development.

The updating of clinical practice guidelines: insights from an international survey

PubMed Central

2011-01-01

Background Clinical practice guidelines (CPGs) have become increasingly popular, and the methodology to develop guidelines has evolved enormously. However, little attention has been given to the updating process, in contrast to the appraisal of the available literature. We conducted an international survey to identify current practices in CPG updating and explored the need to standardize and improve the methods. Methods We developed a questionnaire (28 items) based on a review of the existing literature about guideline updating and expert comments. We carried out the survey between March and July 2009, and it was sent by email to 106 institutions: 69 members of the Guidelines International Network who declared that they developed CPGs; 30 institutions included in the U.S. National Guideline Clearinghouse database that published more than 20 CPGs; and 7 institutions selected by an expert committee. Results Forty-four institutions answered the questionnaire (42% response rate). In the final analysis, 39 completed questionnaires were included. Thirty-six institutions (92%) reported that they update their guidelines. Thirty-one institutions (86%) have a formal procedure for updating their guidelines, and 19 (53%) have a formal procedure for deciding when a guideline becomes out of date. Institutions describe the process as moderately rigorous (36%) or acknowledge that it could certainly be more rigorous (36%). Twenty-two institutions (61%) alert guideline users on their website when a guideline is older than three to five years or when there is a risk of being outdated. Twenty-five institutions (64%) support the concept of "living guidelines," which are continuously monitored and updated. Eighteen institutions (46%) have plans to design a protocol to improve their guideline-updating process, and 21 (54%) are willing to share resources with other organizations. Conclusions Our study is the first to describe the process of updating CPGs among prominent guideline institutions across the world, providing a comprehensive picture of guideline updating. There is an urgent need to develop rigorous international standards for this process and to minimize duplication of effort internationally. PMID:21914177

Clinical practice guidelines (CPGs) for Chinese medicine (CM) are being developed to assist doctors with appropriate decisions concerning CM care. To date, there has been little investigation on the perspectives of those to whom the guidelines are directed. A self-administered questionnaire was sent to 4503 doctors in 28 provinces of China in the latter half of 2012. Questions were organized around the topics of knowledge, application, practice changes, beliefs and outcomes of implementation. Basic classificatory data on specialties and years of qualification were also collected. Replies were received from 4495 CM doctors (99.82%). Of these, 85.56% of CM doctors reported being familiar with CPG recommendations, but the overall adherence rate was only 50.39%. The length of time practicing CM may influence the rate of adherence, since 709 doctors (51.90%) with less than 5 years of experience reported never having followed CPGs. Doctors in nine specialties showed a modest degree of homogeneity in their attitudes towards CM diagnosis and treatment, which were generally positive. Most doctors regarded CPG-recommended therapies as safe (92%), economic (84%), and effective (76%). Approximately four-fifths of those questioned selected 'acceptable' (60.84%) and 'acceptable after revision' (19.23%) regarding their comprehensive assessment of the CPGs. An encouraging result from this survey is that the majority of CM doctors support the concept of CPGs for the practice of CM. However, the results of this survey also suggest that improving the adherence of CM doctors to the guidelines remains a major challenge to improving the practice standards for CM.

Format guidelines to make them vivid, intuitive, and visual: use simple formatting rules to optimize usability and accessibility of clinical practice guidelines.

We present simple formatting rules derived from an extensive literature review that can improve the format of clinical practice guidelines (CPGs), and potentially increase the likelihood of being used. We recently conducted a review of the literature from medicine, psychology, design, and human factors engineering on characteristics of guidelines that are associated with their use in practice, covering both the creation and communication of content. The formatting rules described in this article are derived from that review. The formatting rules are grouped into three categories that can be easily applied to CPGs: first, Vivid: make it stand out; second, Intuitive: match it to the audience's expectations, and third, Visual: use alternatives to text. We highlight rules supported by our broad literature review and provide specific 'how to' recommendations for individuals and groups developing evidence-based materials for clinicians. The way text documents are formatted influences their accessibility and usability. Optimizing the formatting of CPGs is a relatively inexpensive intervention and can be used to facilitate the dissemination of evidence in healthcare. Applying simple formatting principles to make documents more vivid, intuitive, and visual is a practical approach that has the potential to influence the usability of guidelines and to influence the extent to which guidelines are read, remembered, and used in practice.

Knowledge Translation in Audiology

The impetus for evidence-based practice (EBP) has grown out of widespread concern with the quality, effectiveness (including cost-effectiveness), and efficiency of medical care received by the public. Although initially focused on medicine, EBP principles have been adopted by many of the health care professions and are often represented in practice through the development and use of clinical practice guidelines (CPGs). Audiology has been working on incorporating EBP principles into its mandate for professional practice since the mid-1990s. Despite widespread efforts to implement EBP and guidelines into audiology practice, gaps still exist between the best evidence based on research and what is being done in clinical practice. A collaborative dynamic and iterative integrated knowledge translation (KT) framework rather than a researcher-driven hierarchical approach to EBP and the development of CPGs has been shown to reduce the knowledge-to-clinical action gaps. This article provides a brief overview of EBP and CPGs, including a discussion of the barriers to implementing CPGs into clinical practice. It then offers a discussion of how an integrated KT process combined with a community of practice (CoP) might facilitate the development and dissemination of evidence for clinical audiology practice. Finally, a project that uses the knowledge-to-action (KTA) framework for the development of outcome measures in pediatric audiology is introduced. PMID:22194314

Towards symbiosis in knowledge representation and natural language processing for structuring clinical practice guidelines.

The successful adoption by clinicians of evidence-based clinical practice guidelines (CPGs) contained in clinical information systems requires efficient translation of free-text guidelines into computable formats. Natural language processing (NLP) has the potential to improve the efficiency of such translation. However, it is laborious to develop NLP to structure free-text CPGs using existing formal knowledge representations (KR). In response to this challenge, this vision paper discusses the value and feasibility of supporting symbiosis in text-based knowledge acquisition (KA) and KR. We compare two ontologies: (1) an ontology manually created by domain experts for CPG eligibility criteria and (2) an upper-level ontology derived from a semantic pattern-based approach for automatic KA from CPG eligibility criteria text. Then we discuss the strengths and limitations of interweaving KA and NLP for KR purposes and important considerations for achieving the symbiosis of KR and NLP for structuring CPGs to achieve evidence-based clinical practice.

How do we know if a clinical practice guideline is good? A response to Djulbegovic and colleagues' use of fast-and-frugal decision trees to improve clinical care strategies.

Clinical practice guidelines (CPGs) and clinical pathways have become important tools for improving the uptake of evidence-based care. Where CPGs are good, adherence to the recommendations within is thought to result in improved patient outcomes. However, the usefulness of such tools for improving patient important outcomes depends both on adherence to the guideline and whether or not the CPG in question is good. This begs the question of what it is that makes a CPG good? In this issue of the Journal, Djulbegovic and colleagues offer a theory to help guide the development of CPGs. The "fast-and-frugal tree" (FFT) heuristic theory is purported to provide the theoretical structure needed to quantitatively assess clinical guidelines in practice, something that the lack of theory to guide CPG development has precluded. In this paper, I examine the role of FFTs in providing an adequate theoretical framework for developing CPGs. In my view, positioning guideline development within the FFT framework may help with problems related to adherence. However, I believe that FTTs fall short in providing panel members with the theoretical basis needed to justify which factors should be considered when developing a CPG, how information on those factors derived from research studies should be interpreted, and how those factors should be integrated into the recommendation. © 2018 John Wiley & Sons, Ltd.

The South African allied health (AH) primary healthcare (PHC) workforce is challenged with the complex rehabilitation needs of escalating patient numbers. The application of evidence-based care using clinical practice guidelines (CPGs) is one way to make efficient and effective use of resources. Although CPGs are common for AH in high-income countries, there is limited understanding of how to do this in low- to middle-income countries. This paper describes barriers and enablers for AH CPG uptake in South African PHC. Semi-structured individual interviews were undertaken with 25 South African AH managers, policymakers, clinicians and academics to explore perspectives on CPGs. Interviews were conducted by researcher dyads, one being familiar with South African AH PHC practice and the other with CPG expertise. Rigour and transparency of data collection was ensured. Interview transcripts were analysed by structuring content into codes, categories and themes. Exemplar quotations were extracted to support themes. CPGs were generally perceived to be relevant to assist AH providers to address the challenges of consistently providing evidence-based care in South African PHC settings. CPGs were considered to be tools for managing clinical, social and economic complexities of AH PHC practice, particularly if CPG recommendations were contextusalised. CPG uptake was one way to deal with increasing pressures to make efficient use of scarce financial resources, and to demonstrate professional legitimacy. Themes comprised organisational infrastructures and capacities for CPG uptake, interactions between AH actors and interaction with broader political structures, the nature of AH evidence in CPGs, and effectively implementing CPGs into practice. CPGs contextualised to local circumstances offer South African PHC AH services with an efficient vehicle for putting evidence into practice. There are challenges to doing this, related to local barriers such as geography, AH training, workforce availability, scarce resources, an escalating number of patients requiring complex rehabilitation, and local knowledge. Concerted attempts to implement locally relevant CPGs for AH primary care in South Africa are required to improve widespread commitment to evidence-based care, as well as to plan efficient and effective service delivery models.

Perceptions and attitudes of clinicians in Spain toward clinical practice guidelines and grading systems: a protocol for a qualitative study and a national survey

PubMed Central

2010-01-01

Background Clinical practice guidelines (CPGs) have become a very popular tool for decision making in healthcare. While there is some evidence that CPGs improve outcomes, there are numerous factors that influence their acceptability and use by healthcare providers. While evidence of clinicians' knowledge, perceptions and attitudes toward CPGs is extensive, results are still disperse and not conclusive. Our study will evaluate these issues in a large and representative sample of clinicians in Spain. Methods/Design A mixed-method design combining qualitative and quantitative research techniques will evaluate general practitioners (GPs) and hospital-based specialists in Spain with the objective of exploring attitudes and perceptions about CPGs and evidence grading systems. The project will consist of two phases: during the first phase, group discussions will be carried out to gain insight into perceptions and attitudes of the participants, and during the second phase, this information will be completed by means of a survey, reaching a greater number of clinicians. We will explore these issues in GPs and hospital-based practitioners, with or without previous experience in guideline development. Discussion Our study will identify and gain insight into the perceived problems and barriers of Spanish practitioners in relation to guideline knowledge and use. The study will also explore beliefs and attitudes of clinicians towards CPGs and evidence grading systems used to rate the quality of the evidence and the strength of recommendations. Our results will provide guidance to healthcare researchers and healthcare decision makers to improve the use of guidelines in Spain and elsewhere. PMID:21129195

First-order logic theory for manipulating clinical practice guidelines applied to comorbid patients: a case study.

Clinical practice guidelines (CPGs) implement evidence-based medicine designed to help generate a therapy for a patient suffering from a single disease. When applied to a comorbid patient, the concurrent combination of treatment steps from multiple CPGs is susceptible to adverse interactions in the resulting combined therapy (i.e., a therapy established according to all considered CPGs). This inability to concurrently apply CPGs has been shown to be one of the key shortcomings of CPG uptake in a clinical setting1. Several research efforts are underway to address this issue such as the K4CARE2 and GuideLine INteraction Detection Assistant (GLINDA)3 projects and our previous research on applying constraint logic programming to developing a consistent combined therapy for a comorbid patient4. However, there is no generalized framework for mitigation that effectively captures general characteristics of the problem while handling nuances such as time and ordering requirements imposed by specific CPGs. In this paper we propose a first-order logic-based (FOL) approach for developing a generalized framework of mitigation. This approach uses a meta-algorithm and entailment properties to mitigate (i.e., identify and address) adverse interactions introduced by concurrently applied CPGs. We use an illustrative case study of a patient suffering from type 2 diabetes being treated for an onset of severe rheumatoid arthritis to show the expressiveness and robustness of our proposed FOL-based approach, and we discuss its appropriateness as the basis for the generalized theory.

Although clinical practice guidelines (CPGs) have been suggested as a means of encapsulating best practice in evidence-based medical treatment, their usage in clinical environments has been disappointing. Criticisms of guideline representations have been that they are predominantly narrative and are difficult to incorporate into clinical information systems. This paper analyses the use of UML process modelling techniques for guideline representation and proposes the automated generation of executable guidelines using XMI. This hybrid UML-XMI approach provides flexible authoring of guideline decision and control structures whilst integrating appropriate data flow. It also uses an open XMI standard interface to allow the use of authoring tools and process control systems from multiple vendors. The paper first surveys CPG modelling formalisms followed by a brief introduction to process modelling in UMI. Furthermore, the modelling of CPGs in UML is presented leading to a case study of encoding a diabetes mellitus CPG using UML.

Surgical subspecialty societies release clinical practice guidelines (CPGs) to provide topic-specific recommendations to healthcare providers. We hypothesize that there may be significant differences in statement strength and evidence quality both within the American Urological Association (AUA) guidelines and compared to those published by the American Academy of Orthopedic Surgeons (AAOS) and American Academy of Otolaryngology-Head and Neck Surgery (AAO-HNS). CPGs issued through 2017 were extracted from the AUAnet.org. Statements were characterized by evidence basis, strength, and evidence quality. CPGs were compared among urologic subspecialties and to those from the AAOS and AAO-HNS. Analysis used Fisher's exact tests and Student's t-tests with significance p < 0.05. A total of 25 AUA CPGs (672 statements) were reviewed and 34.6% were non-evidence based with the highest proportions in pediatrics (47.5%) and sexual medicine (46.5%). The AUA has published over twice as many statements as the AAOS and quadruple that of the AAO-HNS. A smaller proportion of the AUA statements were evidence-based (65.4%) compared to the AAOS (80.5%, p < 0.001) and AAO-HNS (99.8%, p < 0.001), and fewer used "high" quality evidence (AUA 7.2% versus AAOS 21.2%, p < 0.001; versus AAO-HNS 16.1%, p < 0.001). The AUA has published broad CPGs that far exceed those from the AAOS and AAO-HNS. The AUA has utilized extensive resources to provide guidance to help standardize care among urologists. The AAOS and AAO-HNS may not provide guidelines when evidence is limited. With the continued increase of high quality clinical trials, the AUA will be able to continue improving its robust set of evidence-based CPGs.

Background Adherence to Clinical Practice Guidelines (CPGs) remains suboptimal among internal medicine trainees. Educational games are of growing interest and have the potential to improve adherence to CPGs. The objectives of this study were to develop an educational game to teach CPGs in Internal Medicine residency programs and to evaluate its feasibility and acceptability. Methods We developed the Guide-O-Game© in the format of a TV game show with questions based on recommendations of CPGs. The development of the Guide-O-Game© consisted of the creation of a multimedia interactive tool, the development of recommendation-based questions, and the definition of the game's rules. We evaluated its feasibility through pilot testing and its acceptability through a qualitative process. Results The multimedia interactive tool uses a Macromedia Flash web application and consists of a manager interface and a user interface. The user interface allows the choice of two game styles. We created so far 16 sets of questions relating to 9 CPGs. The pilot testing proved that the game was feasible. The qualitative evaluation showed that residents considered the game to be acceptable. Conclusion We developed an educational game to teach CPGs to Internal Medicine residents that is both feasible and acceptable. Future work should evaluate its impact on educational outcomes.

Currently, very few guidelines for supportive care for children with cancer exist. In the Netherlands, nationwide guidelines are over 10 years old and mostly based on expert opinion. Consequently, there is growing support and need for clinical practice guidelines (CPGs), which ought to be developed with a well-defined methodology and include a systematic search of literature, evidence summaries, and a transparent description of the decision process for the final recommendations. Development of CPGs is time consuming; therefore, it is important to prioritize topics for which there is the greatest clinical demand. This study aims to prioritize childhood cancer supportive care topics for development of CPGs. A Delphi survey consisting of two rounds was conducted to prioritize relevant childhood cancer supportive care topics for the development of CPGs. A group of experts comprising 15 pediatric oncologists, 15 pediatric oncology nurses, and 15 general pediatricians involved in care for childhood cancer patients were invited to participate. All relevant supportive care topics in childhood cancer were rated. In both rounds, 36 panellists (82%) responded. Agreement between panellists was very good, with an intraclass correlation coefficient of 0.918 (95% confidence interval (CI) = 0.849-0.966, p < 0.001) in round 2. The ten topics with the highest score in the final round were infection, sepsis, febrile neutropenia, pain, nausea/vomiting, restrictions in daily life and activities, palliative care, procedural sedation, terminal care, and oral mucositis. We successfully used a Delphi survey to prioritize childhood cancer supportive care topics for the development of CPGs. This is a first step towards uniform and evidence-based Dutch guidelines in supportive care in childhood cancer. Even though performed nationally, we believe that this study can also be regarded as an example starting point for international development of CPGs in the field of supportive care in cancer or any other field for that matter.

To determine the use of clinical practice guidelines (CPGs) for chronic pain (CP) management; analyze the effects of training in pain and the attitudes of physicians toward pain and CP patients on the adherence to these CPGs; and assess the impact of adherence to CPGs on patient care. This was a cross-sectional study in a sample of physicians involved in CP patient management. Information on the use of CPGs for CP management, their training in pain, and their attitudes toward pain, patients, and patient care was collected. Descriptive and bivariate analyses were performed, and a multinomial logistic regression model was constructed to analyze factors associated with the use of CPGs. Of the 257 physicians surveyed, 46.6% were physiatrists, 26.7% were general practitioners, and 26.7% were medical oncologists. Although 96.5% claimed to have received training in pain, only 10.1% had received college training, and 76.3% expressed having gaps in their knowledge; 53.9% stated they applied CPGs often/always, and 12.5% rarely/never. Limited knowledge on pain, reduced involvement in training activities, more negative attitudes toward patients, and having experienced CP were the factors related to reduced adherence to CPGs, especially among the youngest respondents. The greater the use of CPGs, the better the patient care was. Access to scientific information and specialized training are factors related to the use of CPGs for pain treatment. Therefore, the inclusion of CP training in university and during medical specialty training will be essential measures to improve adherence to CPG, thereby improving patient care and pain control. © 2017 World Institute of Pain.

Purpose: To develop clinical practice guidelines (CPGs) for prevention, diagnosis, treatment and follow-up of ocular injuries caused by exposure to mustard gas. Methods: The clinical questions were designed by the guideline team. Websites and databases including National Guidelines Clearinghouse, National Institute for Clinical Excellence, Cochrane, and PubMed were searched to find related CPGs and explore possible answers to the clinical questions. Since there were no relevant CPGs in the literature, related articles in Persian and English languages were extracted. Each article along with its level of evidence was summarized. Additionally, hand search was performed by looking the reference list of each article. Consequently, recommendations were developed considering the clinical benefits and side effects of each therapeutic modality. The recommendations were re-evaluated in terms of customization criteria. All recommendations along with the related evidence were scored from 1 to 9 by experts from all medical universities of Iran. The level of agreement among the experts was evaluated by analyzing the given scores. Results: The agreement was achieved for all recommendations. The experts suggested a number of minor modifications which were applied to the recommendations. Finally, CPGs were developed with 98 recommendations under three major domains including prevention of injury, diagnosis and management of the acute and delayed-onset mustard gas ocular injuries. Conclusion: Considering the lack of CPGs for the prevention, diagnosis, and management of mustard gas-induced keratitis, these recommendations would be useful to prevent the serious ocular complications of mustard gas and standardize eye care services to the affected individuals.

To develop clinical practice guidelines (CPGs) for prevention, diagnosis, treatment and follow-up of ocular injuries caused by exposure to mustard gas. The clinical questions were designed by the guideline team. Websites and databases including National Guidelines Clearinghouse, National Institute for Clinical Excellence, Cochrane, and PubMed were searched to find related CPGs and explore possible answers to the clinical questions. Since there were no relevant CPGs in the literature, related articles in Persian and English languages were extracted. Each article along with its level of evidence was summarized. Additionally, hand search was performed by looking the reference list of each article. Consequently, recommendations were developed considering the clinical benefits and side effects of each therapeutic modality. The recommendations were re-evaluated in terms of customization criteria.

Clinical practice CPGs (CPGs) have been developed to summarize evidence related to the management of osteoarthritis (OA). CPGs facilitate uptake of evidence-based knowledge by consumers, health professionals, health administrators and policy makers. The objectives of the present review were: 1) to assess the quality of the CPGs on non-pharmacological management of OA; using a standardized and validated instrument - the Appraisal of Guidelines Research and Evaluation (AGREE II) tool - by three pairs of trained appraisers; and 2) to summarize the recommendations based on only high-quality existing CPGs. Scientific literature databases from 2001 to 2013 were systematically searched for the state of evidence, with 17 CPGs for OA being identified. Most CPGs effectively addressed only a minority of AGREE II domains. Scope and purpose was effectively addressed in 10 CPGs on the management of OA, stakeholder involvement in 12 CPGs, rigour of development in 10 CPGs, clarity/presentation in 17 CPGs, editorial independence in 2 CPGs, and applicability in none of the OA CPGs. The overall quality of the included CPGs, according to the 7-point AGREE II scoring system, is 4.8±0.41 for OA. Therapeutic exercises, patient education, transcutaneous electrical nerve stimulation, acupuncture, orthoses and insoles, heat and cryotherapy, patellar tapping, and weight control are commonly recommended for the non-pharmacological management of OA by the high-quality CPGs. The general clinical management recommendations tended to be similar among high-quality CPGs, although interventions addressed varied. Non-pharmacological management interventions were superficially addressed in more than half of the selected CPGs. For CPGs to be standardized uniform creators should use the AGREE II criteria when developing CPGs. Innovative and effective methods of CPG implementation to users are needed to ultimately enhance the quality of life of arthritic individuals. PMID:24427268

Clinical practice guidelines (CPGs) aim to improve professionalism in health care. However, current CPG development manuals fail to address how to include ethical issues in a systematic and transparent manner. The objective of this study was to assess the representation of ethical issues in general CPGs on dementia care. To identify national CPGs on dementia care, five databases of guidelines were searched and national psychiatric associations were contacted in August 2011 and in June 2013. A framework for the assessment of the identified CPGs' ethical content was developed on the basis of a prior systematic review of ethical issues in dementia care. Thematic text analysis and a 4-point rating score were employed to assess how ethical issues were addressed in the identified CPGs. Twelve national CPGs were included. Thirty-one ethical issues in dementia care were identified by the prior systematic review. The proportion of these 31 ethical issues that were explicitly addressed by each CPG ranged from 22% to 77%, with a median of 49.5%. National guidelines differed substantially with respect to (a) which ethical issues were represented, (b) whether ethical recommendations were included, (c) whether justifications or citations were provided to support recommendations, and (d) to what extent the ethical issues were explained. Ethical issues were inconsistently addressed in national dementia guidelines, with some guidelines including most and some including few ethical issues. Guidelines should address ethical issues and how to deal with them to help the medical profession understand how to approach care of patients with dementia, and for patients, their relatives, and the general public, all of whom might seek information and advice in national guidelines. There is a need for further research to specify how detailed ethical issues and their respective recommendations can and should be addressed in dementia guidelines.

Goda, Tamara S; Sherrod, Brad; Kindell, Linda

Transfusion practices vary extensively for patients undergoing cardiac surgical procedures, leading to high utilization of blood products despite evidence that transfusions negatively impact outcomes. An important factor affecting transfusion practice is recognition of the importance of teams in cardiac surgery care delivery. This article reports an evidenced-based practice (EBP) initiative constructed using the Society of Thoracic Surgery (STS) 2011 Blood Conservation Clinical Practice Guidelines (CPGs) to standardize transfusion practice across the cardiac surgery team at a large academic medical center. Project outcomes included: a) Improvement in clinician knowledge related to the STS Blood Conservation CPGs; and b) Decreased blood product utilization for patients undergoing cardiac surgical procedures. Participants' scores reflected an improvement in the overall knowledge of the STS CPGs noting a 31.1% (p = 0.012) increase in the number of participants whose practice reflected the Blood Conservation CPGs post intervention. Additionally, there was a reduction in overall blood product utilization for all patients undergoing cardiac surgery procedures post intervention (p = 0.005). Interdisciplinary education based on the STS Blood Conservation CPGs is an effective way to reduce transfusion practice variability and decrease utilization of blood products during cardiac surgery.

Objectives Considering equity into guidelines presents methodological challenges. This study aims to qualitatively synthesise the methods for incorporating equity in clinical practice guidelines (CPGs). Setting Content analysis of methodological publications. Eligibility criteria for selecting studies Methodological publications were included if they provided checklists/frameworks on when, how and to what extent equity should be incorporated in CPGs. Data sources We electronically searched MEDLINE, retrieved references, and browsed guideline development organisation websites from inception to January 2013. After study selection by two authors, general characteristics and checklists items/framework components from included studies were extracted. Based on the questions or items from checklists/frameworks (unit of analysis), content analysis was conducted to identify themes and questions/items were grouped into these themes. Primary outcomes The primary outcomes were methodological themes and processes on how to address equity issues in guideline development. Results 8 studies with 10 publications were included from 3405 citations. In total, a list of 87 questions/items was generated from 17 checklists/frameworks. After content analysis, questions were grouped into eight themes (‘scoping questions’, ‘searching relevant evidence’, ‘appraising evidence and recommendations’, ‘formulating recommendations’, ‘monitoring implementation’, ‘providing a flow chart to include equity in CPGs’, and ‘others: reporting of guidelines and comments from stakeholders’ for CPG developers and ‘assessing the quality of CPGs’ for CPG users). Four included studies covered more than five of these themes. We also summarised the process of guideline development based on the themes mentioned above. Conclusions For disadvantaged population-specific CPGs, eight important methodological issues identified in this review should be considered when including equity in CPGs under the guidance of a scientific guideline development manual.

Purpose: To customize clinical practice guidelines (CPGs) for management of diabetic retinopathy (DR) in the Iranian population. Methods: Three DR CPGs (The Royal College of Ophthalmologists 2013, American Academy of Ophthalmology [Preferred Practice Pattern 2012], and Australian Diabetes Society 2008) were selected from the literature using the AGREE tool. Clinical questions were designed and summarized into four tables by the customization team. The components of the clinical questions along with pertinent recommendations extracted from the above-mentioned CPGs; details of the supporting articles and their levels of evidence; clinical recommendations considering clinical benefits, cost and side effects; and revised recommendations based on customization capability (applicability, acceptability, external validity) were recorded in 4 tables, respectively. Customized recommendations were sent to the faculty members of all universities across the country to score the recommendations from 1 to 9. Results: Agreed recommendations were accepted as the final recommendations while the non-agreed ones were approved after revision. Eventually, 29 customized recommendations under three major categories consisting of screening, diagnosis and treatment of DR were developed along with their sources and levels of evidence. Conclusion: This customized CPGs for management of DR can be used to standardize the referral pathway, diagnosis and treatment of patients with diabetic retinopathy. PMID:27994809

Physical activity, sedentary and sleep behaviours have strong associations with health. This systematic review aimed to identify how clinical practice guidelines (CPGs) for the management of chronic obstructive pulmonary disease (COPD) report specific recommendations and strategies for these movement behaviours. A systematic search of databases (Medline, Scopus, CiNAHL, EMbase, Clinical Guideline), reference lists and websites identified current versions of CPGs published since 2005. Specific recommendations and strategies concerning physical activity, sedentary behaviour and sleep were extracted verbatim. The proportions of CPGs providing specific recommendations and strategies were reported. From 2370 citations identified, 35 CPGs were eligible for inclusion. Of these, 21 (60%) provided specific recommendations for physical activity, while none provided specific recommendations for sedentary behaviour or sleep. The most commonly suggested strategies to improve movement behaviours were encouragement from a healthcare provider (physical activity n = 20; sedentary behaviour n = 2) and referral for a diagnostic sleep study (sleep n = 4). Since optimal physical activity, sedentary behaviour and sleep durations and patterns are likely to be associated with mitigating the effects of COPD, as well as with general health and well-being, there is a need for further COPD-specific research, consensus and incorporation of recommendations and strategies into CPGs.

Beneficial effects of clinical practice guidelines (CPGs) have not yet reached expectations due to limited routine adoption. Electronic distribution and reminder systems have the potential to overcome implementation barriers. Existing electronic CPG repositories like the National Guideline Clearinghouse (NGC) provide individual access but lack standardized computer-readable interfaces necessary for automated guideline retrieval. The aim of this paper was to facilitate automated context-based selection and presentation of CPGs. Using attributes from the NGC classification scheme, an XML-based metadata repository was successfully implemented, providing document storage, classification and retrieval functionality. Semi-automated extraction of attributes was implemented for the import of XML guideline documents using XPath. A hospital information system interface was exemplarily implemented for diagnosis-based guideline invocation. Limitations of the implemented system are discussed and possible future work is outlined. Integration of standardized computer-readable search interfaces into existing CPG repositories is proposed. PMID:12463831

The use of lithium for the treatment of bipolar disorder: Recommendations from clinical practice guidelines.

PubMed

Malhi, Gin S; Gessler, Danielle; Outhred, Tim

2017-08-01

Lithium is an effective mood stabilizer that is used principally for the management of bipolar disorder (BD). Its administration is complex and often requires sophisticated management and assiduous monitoring. When considering the use of lithium therapy for bipolar disorder, clinicians are advised to refer to recommendations outlined in clinical practice guidelines (CPGs); but because of varying emphases placed by different international CPGs, recommendations addressing the practical use of lithium lack consistency. In order to inform clinicians of optimal lithium therapy for bipolar disorder, we compared and synthesized recommendations for the treatment of bipolar disorder made by recognized CPGs internationally. We conducted a search of the literature and extracted guidance across multiple clinical issues, including clinical indications, disorder subtypes, additional uses, special populations, practical aspects, and side effects. Collectively, CPGs consider lithium most robustly as a first-line intervention for maintenance treatment of bipolar disorder and strongly for the treatment of mania, with relatively modest support for the management of acute bipolar depression. Additionally, there is consensus across the CPGs that lithium tangibly reduces the risk of suicide. Generally, CPGs provide guidance on the many facets of initiating and maintaining patients on lithium therapy, but individually the CPGs varied in terms of depth and practical guidance they provide across these areas. However, consensus was established across many key areas of practice such as the ideal lithium plasma concentration for maintenance and monitoring (0.6-0.8mmol/L), along with the need for regular monitoring of renal and endocrine function. However, with more complex aspects (e.g., atypical presentations) and in special populations (e.g., youth; pregnancy and post-partum; older adults), guidance varied considerably and clear consensus recommendations were more difficult to achieve. In younger adults desirable plasma lithium levels of 0.6-0.8mmol/L can perhaps be achieved with comparatively lower doses and in the very elderly it may be prudent to target lower plasma levels in the first instance. These are important practical points for consideration that, along with many others offered throughout the article, should assist clinicians in dissecting the more complex aspects of management with greater precision. This review was limited to CPGs written in English. CPGs are themselves limited by reliance on evidence that often has little resemblance to real-world presentations. An important area that is not sufficiently addressed in the CPGs is clear guidance on the cessation of lithium therapy. Further research is needed on many aspects of lithium therapy and this alongside existing knowledge needs to be used more consistently to inform CPGs, which should also incorporate empirical evidence and clinical experience. The recommendations in this paper provide a useful synthesis of guidance available currently. Copyright © 2017 Elsevier B.V. All rights reserved.

The purpose of this paper is to present differences in mental models of clinical practice guidelines (CPGs) among 15 Veterans Health Administration (VHA) facilities throughout the United States. Two hundred and forty-four employees from 15 different VHA facilities across four service networks around the country were invited to participate. Participants were selected from different levels throughout each service setting from primary care personnel to facility leadership. This qualitative study used purposive sampling, a semistructured interview process for data collection, and grounded theory techniques for analysis. A semistructured interview was used to collect information on participants' mental models of CPGs, as well as implementation strategies and barriers in their facility. Analysis of these interviews using grounded theory techniques indicated that there was wide variability in employees' mental models of CPGs. Findings also indicated that high-performing facilities exhibited both (a) a clear, focused shared mental model of guidelines and (b) a tendency to use performance feedback as a learning opportunity, thus suggesting that a shared mental model is a necessary but not sufficient step toward successful guideline implementation. We conclude that a clear shared mental model of guidelines, in combination with a learning orientation toward feedback are important components for successful guideline implementation and improved quality of care.

Clinical practice guidelines (CPGs) are not readily implemented in clinical practice. One of the impeding factors is that physical therapists do not hold realistic perceptions of their adherence to CPGs. Peer assessment (PA) is an implementation strategy that aims at improving guideline adherence by enhancing reflective practice, awareness of professional performance, and attainment of personal goals. The purpose of this study was to compare the effectiveness of PA with the usual case discussion (CD) strategy on adherence to CPGs for physical therapist management of upper extremity complaints. A single-masked, cluster-randomized controlled trial with pretest-posttest design was conducted. Twenty communities of practice (n=149 physical therapists) were randomly assigned to groups receiving PA or CD, with both interventions consisting of 4 sessions over 6 months. Both PA and CD groups worked on identical clinical cases relevant to the guidelines. Peer assessment focused on individual performance observed and evaluated by peers; CD focused on discussion. Guideline adherence was measured with clinical vignettes, reflective practice was measured with the Self-Reflection and Insight Scale (SRIS), awareness of performance was measured via the correlation between perceived and assessed improvement, and attainment of personal goals was measured with written commitments to change. The PA groups improved more on guideline adherence compared with the CD groups (effect=22.52; 95% confidence interval [95% CI]=2.38, 42.66; P=.03). The SRIS scores did not differ between PA and CD groups. Awareness of performance was greater for the PA groups (r=.36) than for the CD groups (r=.08) (effect=14.73; 95% CI=2.78, 26.68; P=.01). The PA strategy was more effective than the CD strategy in attaining personal goals (effect=0.50; 95% CI=0.04, 0.96; P=.03). Limited validity of clinical vignettes as a proxy measure of clinical practice was a limitation of the study. Peer assessment was more effective than CD in improving adherence to CPGs. Personal feedback may have contributed to its effectiveness. Future research should address the role of the group coach. © 2015 American Physical Therapy Association.

Clinical practice guidelines (CPGs) and consensus statements (CSs) are used to apply evidence-based medicine or expert recommendations to clinical practice. Here we explore author financial conflicts of interest (FCOIs), sources of guideline funding, and their relationship with endorsement of specific drugs. An electronic search of MEDLINE was conducted to identify CPGs and CSs for common solid cancers published between January 2003 and October 2013. The search was restricted to articles evaluating systemic therapy. We extracted data on self-reported author FCOIs, funding sources, use of manuscript writers, and endorsement of specific drugs in the abstract of the article. Of 142 articles evaluated, 64% were CPGs, and 36% were CSs. The proportion of articles reporting FCOIs improved from 11% in 2003 to 93% in 2013 (P for trend < .001). Only 45% of articles explicitly reported funding sources. Of these, 65% disclosed partial or full industry sponsorship. Use of manuscript writers was declared in 13%, but many articles did not explicitly report the role of authors in the writing of the manuscript. Endorsement of specific drugs was significantly associated with author FCOIs (odds ratio [OR], 7.29; P = .001), but not with industry funding (OR, 0.95; P = .37). Reporting of FCOIs in CPGs and CSs has improved over time. Despite prevalent funding of guideline development by industry, such funding is not associated with endorsement of specific drugs. Author FCOIs are prevalent, and endorsement of a specific drug seems to be more common when authors have FCOIs with the pharmaceutical company marketing that drug. © 2014 by American Society of Clinical Oncology.

Assessing the Methodological Quality of Glaucoma Clinical Practice Guidelines and Their Recommendations on Microinvasive Glaucoma Surgery: A Systematic Review.

Clinical practice guidelines (CPG) are regarded by many as critical communications providing guidance within specific medical fields. Over a decade ago, the first microinvasive glaucoma surgical (MIGS) procedures were introduced. Since then, a number of these novel intraocular pressure controlling surgical options have been approved worldwide. Governing bodies and health care administration often utilize CPGs when considering funding for newer technologies. This highlights the importance of well-written, accurate, and up-to-date CPGs in the rapidly evolving field of MIGS. If CPGs are unable to fill this role, their use in treatment decision-making is doing a disservice to patients, who will be denied currently available and potentially superior care. To determine the overall value of a CPG, the methodological quality with which it was developed, in addition to the current relevance and appropriateness of its recommendations, should be evaluated. The objective of the present study was to assess the methodological quality of currently available international glaucoma CPGs, as well as their coverage of MIGS as a surrogate marker of relevance and appropriateness to policy-makers and ophthalmologists alike. To identify potentially relevant CPGs, a predefined search strategy was used to search the following databases: Medline, EMBASE, BIOSIS, and Web of Science. All CPGs related to adult glaucoma and published in English were included. CPG methodological quality was assessed by 3 individuals using the Appraisal of Guidelines for Research and Evaluation II (AGREE II) tool. Studies were then assessed for coverage of MIGS devices and procedures. Search strategy and subsequent screening identified 11 CPGs for analysis. Eight were of high quality according to the AGREE II criteria. Three included basic information on MIGS, but none provided specific recommendations regarding their indications or which patient populations would benefit most. Many international glaucoma CPGs are of high methodological quality. However, coverage of MIGS is sparse, nonspecific and in many instances, absent. This causes CPGs to be a suboptimal source in guiding physicians and health policy-makers in areas characterized by novel and/or rapidly evolving technologies. Mechanisms to incorporate updated evidence in CPGs would have to be considered before they can be used as a source of contemporary clinical decision-making.

The impact of adherence to clinical practice guidelines (CPGs) for loco-regional treatment (i.e. surgery and radiotherapy) and chemotherapy on local disease control and survival in sarcoma patients was investigated in a European study conducted in an Italian region (Veneto). The completeness of the adherence to the Italian CPGs for sarcomas treatment was assessed by comparing the patient's charts and the CPGs. Propensity score-adjusted multivariate survival analysis was used to assess the impact of CPGs adherence on patient clinical outcomes. A total of 151 patients were included. Adherence to CPGs for loco-regional therapy and chemotherapy was observed in 106 out of 147 (70.2%) and 129 out of 139 (85.4%) patients, respectively. Non-adherence to CPGs for loco-regional treatment was independently associated with AJCC stage III disease [odds ratio (OR) 1.77, P = 0.011] and tumor-positive excision margin (OR 3.55, P = 0.003). Patients not treated according to the CPGs were at a higher risk of local recurrence [hazard ratio (HR) 5.4, P < 0.001] and had a shorter sarcoma-specific survival (HR 4.05, P < 0.001), independently of tumor stage. Incomplete adherence to CPGs for loco-regional treatment of sarcomas was associated with worse prognosis in patients with non-metastatic tumors.

Objectives Rehabilitation clinical practice guidelines (CPGs) contain recommendation statements aimed at optimising care for adults with stroke and other brain injury. The aim of this study was to determine the quality, scope and consistency of CPG recommendations for rehabilitation covering the acquired brain injury populations. Design Systematic review. Interventions Included CPGs contained recommendations for inpatient rehabilitation or community rehabilitation for adults with an acquired brain injury diagnosis (stroke, traumatic or other non-progressive acquired brain impairments). Electronic databases (n=2), guideline organisations (n=4) and websites of professional societies (n=17) were searched up to November 2017. Two independent reviewers used the Appraisal of Guidelines for Research and Evaluation (AGREE) II instrument, and textual syntheses were used to appraise and compare recommendations. Results From 427 papers screened, 20 guidelines met the inclusion criteria. Only three guidelines were rated high (>75%) across all domains of AGREE-II; highest rated domains were ‘scope and purpose’ (85.1, SD 18.3) and ‘clarity’ (76.2%, SD 20.5). Recommendations for assessment and for motor therapies were most commonly reported, however, varied in the level of detail across guidelines. Conclusion Rehabilitation CPGs were consistent in scope, suggesting little difference in rehabilitation approaches between vascular and traumatic brain injury. There was, however, variability in included studies and methodological quality. PROSPERO registration number CRD42016026936. PMID:29490958

Academy of Osseointegration's Summit on Clinical Practice Guidelines for the Edentulous Maxilla: Overview, Process, and Outcomes-Changing the Face of Implant Dentistry.

Stanford, Clark M

2016-01-01

Starting in 2012, the Academy of Osseointegration initiated the planning process for an AO Summit to develop clinical practice guidelines (CPGs) for management of the edentulous maxilla. A planning committee led by Professor Clark Stanford and Dr Ole Jensen created a work plan based on five domain areas to be addressed by the summit. The five domain areas were defined as: (1) role of grafting for ridge development for implant placement, (2) role of implant design and systems in management of the edentulous maxilla, (3) role of imaging to guide implant placement, (4) role of biologics to assist in ridge development, and (5) role of prosthetic management. The summit was held in August 2014, and the results are presented in this overview. All of the supporting systematic reviews and the detailed CPGs are presented in this special edition of JOMI. While the evidence was observed to be weak in regard to the literature for most of the systematic reviews, the summit strived to establish the current best evidence and practical CPGs that will assist clinicians in practice.

Objectives Clinical practice guidelines (CPGs) support the translation of research evidence into clinical practice. Key health questions in CPGs ensure that recommendations will be applicable to the clinical context in which the guideline is used. The objectives of this study were to identify CPGs for the pharmacological treatment of first-episode schizophrenia; assess the quality of these guidelines using the Appraisal of Guidelines for Research and Evaluation II (AGREE II) instrument; and compare recommendations in relation to the key health questions that are relevant to the pharmacological treatment of first-episode schizophrenia. Methods A multidisciplinary group identified key health questions that are relevant to the pharmacological treatment of first-episode schizophrenia. The MEDLINE and EMBASE databases, websites of professional organisations and international guideline repositories, were searched for CPGs that met the inclusion criteria. The AGREE II instrument was applied by three raters and data were extracted from the guidelines in relation to the key health questions. Results In total, 3299 records were screened. 10 guidelines met the inclusion criteria. 3 guidelines scored well across all domains. Recommendations varied in specificity. Side effect concerns, rather than comparative efficacy benefits, were a key consideration in antipsychotic choice. Antipsychotic medication is recommended for maintenance of remission following a first episode of schizophrenia but there is a paucity of evidence to guide duration of treatment. Clozapine is universally regarded as the medication of choice for treatment resistance. There is less evidence to guide care for those who do not respond to clozapine. Conclusions An individual's experience of using antipsychotic medication for the initial treatment of first-episode schizophrenia may have implications for future engagement, adherence and outcome. While guidelines of good quality exist to assist in medicines optimisation, the evidence base required to answer key health questions relevant to the pharmacological treatment of first-episode schizophrenia is limited.

Objectives: Physical activity, sedentary and sleep behaviours have strong associations with health. This systematic review aimed to identify how clinical practice guidelines (CPGs) for the management of chronic obstructive pulmonary disease (COPD) report specific recommendations and strategies for these movement behaviours. Methods: A systematic search of databases (Medline, Scopus, CiNAHL, EMbase, Clinical Guideline), reference lists and websites identified current versions of CPGs published since 2005. Specific recommendations and strategies concerning physical activity, sedentary behaviour and sleep were extracted verbatim. The proportions of CPGs providing specific recommendations and strategies were reported. Results: From 2370 citations identified, 35 CPGs were eligible for inclusion. Of these, 21 (60%) provided specific recommendations for physical activity, while none provided specific recommendations for sedentary behaviour or sleep. The most commonly suggested strategies to improve movement behaviours were encouragement from a healthcare provider (physical activity n = 20; sedentary behaviour n = 2) and referral for a diagnostic sleep study (sleep n = 4). Conclusion: Since optimal physical activity, sedentary behaviour and sleep durations and patterns are likely to be associated with mitigating the effects of COPD, as well as with general health and well-being, there is a need for further COPD-specific research, consensus and incorporation of recommendations and strategies into CPGs.

Financial relationships between physicians and industry have influence on patient care. Therefore, organizations producing clinical practice guidelines (CPGs) must have policies limiting financial conflicts during guideline development. To evaluate payments received by physician authors of otolaryngology CPGs, compare disclosure statements for accuracy, and investigate the extent to which the American Academy of Otolaryngology-Head and Neck Surgery complied with standards for guideline development from the Institute of Medicine (IOM). This cross-sectional analysis retrieved CPGs from the American Academy of Otolaryngology-Head and Neck Surgery Foundation that were published or revised from January 1, 2013, through December 31, 2015, by 49 authors. Data were retrieved from December 1 through 31, 2016. Industry payments received by authors were extracted using the Centers for Medicare & Medicaid Services Open Payments database. The values and types of these payments were then evaluated and used to determine whether self-reported disclosure statements were accurate and whether guidelines adhered to applicable IOM standards. The monetary amounts and types of payments received by physicians who author otolaryngology guidelines and the accuracy of disclosure statements. Of the 49 physicians in this sample, 39 (80%) received an industry payment. Twenty-one authors (43%) accepted more than $1000; 12 (24%), more than $10 000; 7 (14%), more than $50 000; and 2 (4%), more than $100 000. Mean (SD) financial payments amounted to $18 431 ($53 459) per physician. Total reimbursement for all authors was $995 282. Disclosure statements disagreed with the Open Payments database for 3 authors, amounting to approximately $20 000 among them. Of the 3 IOM standards assessed, only 1 was consistently enforced. Some CPG authors failed to fully disclose all financial conflicts of interest, and most guideline development panels and chairpersons had conflicts. In addition, adherence to IOM standards for guideline development was lacking. This study is relevant to CPG panels authoring recommendations, physicians implementing CPGs to guide patient care, and the organizations establishing policies for guideline development.

To determine the characteristics of curricula for teaching the content of clinical practice guidelines (CPGs) in psychiatric residency and child and adolescent fellowship programs as well as to determine if and how the learning of CPG content is applied in clinical care settings. We conducted a national online survey of directors of general psychiatry residency and child and adolescent fellowship programs in the USA. The survey questionnaire included 13 brief questions about the characteristics used to teach CPGs in the programs, as well as two demographic questions about each program and director. Descriptive statistics were reported for each questionnaire item by program classification (i.e., child and adolescent vs. general psychiatry). The survey response rate was 49.8% (146 out of 293). Just 23% of programs reported having written goals and objectives related to teaching CPGs. The most frequently taught aspect of CPGs was their content (72% of programs). Didactic sessions were the most frequently employed teaching strategy (79% of programs). Regarding the application of CPG learning in treatment care settings, just 16% of programs applied algorithms in care settings, and 15% performed evaluations to determine consistency between CPG recommendations and care delivery. Only 8% of programs utilized audit and feedback to residents about their adherence to CPGs. Faculty time constraints and insufficient interest were the leading barriers (39% and 33% of programs, respectively) to CPG teaching, although 38% reported no barriers. However, child and adolescent programs less commonly identified insufficient interest among faculty as a barrier to teaching CPGs compared to general programs (20% vs. 43%). Moreover, compared to general programs, child and adolescent fellowship programs taught more aspects of CPGs, used more educational activities to teach the content of specific CPGs, and used more methods to evaluate the teaching of CPGs. Although the majority of programs provided some teaching of CPGs, the rigorousness of the teaching approaches was limited, especially attempts to evaluate the extent and effectiveness of their use in clinical care. Child and adolescent fellowship programs provided more extensive teaching and evaluation related to CPGs.

Implementation of clinical practice guidelines (CPGs) has been shown to reduce variation in practice and improve health care quality and patients' safety. There is a limited experience of CPG implementation (CPGI) in the Middle East. The CPG program in our institution was launched in 2009. The Quality Management department conducted a Failure Mode and Effect Analysis (FMEA) for further improvement of CPGI. This is a prospective study of a qualitative/quantitative design. Our FMEA included (1) process review and recording of the steps and activities of CPGI; (2) hazard analysis by recording activity-related failure modes and their effects, identification of actions required, assigned severity, occurrence, and detection scores for each failure mode and calculated the risk priority number (RPN) by using an online interactive FMEA tool; (3) planning: RPNs were prioritized, recommendations, and further planning for new interventions were identified; and (4) monitoring: after reduction or elimination of the failure mode. The calculated RPN will be compared with subsequent analysis in post-implementation phase. The data were scrutinized from a feedback of quality team members using a FMEA framework to enhance the implementation of 29 adapted CPGs. The identified potential common failure modes with the highest RPN (≥ 80) included awareness/training activities, accessibility of CPGs, fewer advocates from clinical champions, and CPGs auditing. Actions included (1) organizing regular awareness activities, (2) making CPGs printed and electronic copies accessible, (3) encouraging senior practitioners to get involved in CPGI, and (4) enhancing CPGs auditing as part of the quality sustainability plan. In our experience, FMEA could be a useful tool to enhance CPGI. It helped us to identify potential barriers and prepare relevant solutions. © 2017 John Wiley & Sons, Ltd.

Despite availability of clinical practice guidelines (CPGs), gaps in autonomic dysreflexia (AD) knowledge and practice persist. A free, online educational module, the "ABCs of AD", was developed to improve knowledge of the AD-CPGs among emergency healthcare personnel. We examine short-term changes in paramedic and nurse trainees' knowledge of, and social cognitions towards using, the AD-CPGs following module completion. Pre-post. Thirty-four paramedic and nurse trainees from two training programs in Canada completed measures immediately before and after viewing the online "ABCs of AD" module. AD knowledge test; Theory of Planned Behavior social cognition questionnaire; module feedback survey. Paired samples t-tests revealed significant increases in participants' AD knowledge test scores (M ± SDpre = 9.00 ± 2.46, M ± SDpost = 12.03 ± 4.07, P < 0.001; d = 0.84). Prior to viewing the module, participants reported positive social cognitions for using the AD-CPGs (all Ms ≥ 4.84 out of 7). From pre- to post-module, no significant changes were seen in participants' social cognitions for using the AD-CPGs. Participants' average module viewing time was 36.73 ± 24.17 minutes (range 8-90 minutes). There was a decline in viewing from the first to the last module sections, with only half of participants viewing all six sections. Knowledge alone is insufficient for clinical behavior change; as such, social cognitive determinants of behavior should be explicitly targeted in future iterations of the module to increase the likelihood of increased use of the AD-CPGs. To engage viewers across all module sections, the "ABCs of AD" module should include supplementary learning strategies, such as interactive quizzes and peer-to-peer interaction.

Clinical practice guidelines (CPGs) are significant tools for evidence-based health care quality improvement. The CPG program at King Saud University was launched as a quality improvement program to fulfil the international accreditation standards. This program was a collaboration between the Research Chair for Evidence-Based Healthcare and Knowledge Translation and the Quality Management Department. This study aims to develop a fast-track method for adaptation of evidence-based CPGs and describe results of the program. Twenty-two clinical departments participated in the program. Following a CPGs awareness week directed to all health care professionals (HCPs), 22 teams were trained to set priorities, search, screen, assess, select, and customize the best available CPGs. The teams were technically supported by the program's CPG advisors. To address the local health care context, a modified version of the ADAPTE was used where recommendations were either accepted or rejected but not changed. A strict peer-review process for clinical content and methodology was employed. In addition to raising awareness and building capacity, 35 CPGs were approved for implementation by March 2018. These CPGs were integrated with other existing projects such as accreditation, electronic medical records, performance management, and training and education. Preliminary implementation audits suggest a positive impact on patient outcomes. Leadership commitment was a strength, but the high turnover of the team members required frequent and extensive training for HCPs. This model for CPG adaptation represents a quick, practical, economical method with a sense of ownership by staff. Using this modified version can be replicated in other countries to assess its validity. © 2018 John Wiley & Sons, Ltd.

Food and dietary pattern-based recommendations: an emerging approach to clinical practice guidelines for nutrition therapy in diabetes.

PubMed

Sievenpiper, John L; Dworatzek, Paula D N

2013-02-01

Clinical practice guidelines (CPGs) for the nutritional management of diabetes mellitus have evolved considerably over the last 25 years. As major diabetes associations have focussed on the individualization of nutrition therapy, there has been a move toward a broader more flexible macronutrient distribution that emphasizes macronutrient quality over quantity. There is now a call for the integration of food- and dietary pattern-based approaches into diabetes association CPGs. The main argument has been that an approach that focuses on nutrients alone misses important nutrient interactions oversimplifying the complexity of foods and dietary patterns, both of which have been shown to have a stronger influence on disease risk than nutrients alone. Although cancer and heart associations have begun to integrate this approach into their dietary guidelines, diabetes associations have not yet adopted this approach. We provide a rationale for the adoption of this approach for The Canadian Diabetes Association (CDA) 2013 CPGs for nutrition therapy. The systematic review for the development of these guidelines revealed emerging evidence to support the use of vegetarian, Mediterranean, and Dietary Approaches to Stop Hypertension (DASH) dietary patterns as well as specific foods such as dietary pulses and nuts in people with diabetes. Popular and conventional weight loss diets were also found to have similar advantages in people with diabetes, although poor dietary adherence remains an issue with these diets. The CDA 2013 CPGs will support an even greater individualization of nutrition therapy for people with diabetes and appeal to a broader range of practice styles of health professionals.

Objective The purpose of this paper is to present differences in mental models of clinical practice guidelines (CPGs) among 15 Veterans Health Administration (VHA) facilities throughout the United States. Data Sources Two hundred and forty-four employees from 15 different VHA facilities across four service networks around the country were invited to participate. Participants were selected from different levels throughout each service setting from primary care personnel to facility leadership. Study Design This qualitative study used purposive sampling, a semistructured interview process for data collection, and grounded theory techniques for analysis. Data Collection A semistructured interview was used to collect information on participants' mental models of CPGs, as well as implementation strategies and barriers in their facility. Findings Analysis of these interviews using grounded theory techniques indicated that there was wide variability in employees' mental models of CPGs. Findings also indicated that high-performing facilities exhibited both (a) a clear, focused shared mental model of guidelines and (b) a tendency to use performance feedback as a learning opportunity, thus suggesting that a shared mental model is a necessary but not sufficient step toward successful guideline implementation. Conclusions We conclude that a clear shared mental model of guidelines, in combination with a learning orientation toward feedback are important components for successful guideline implementation and improved quality of care.

Single-group pre-/post-test with 3- and 6-month follow-ups. To test the effects of the 'ABCs of AD' educational module on immediate and longer-term changes in paramedics' knowledge and beliefs about using the autonomic dysreflexia clinical practice guidelines (AD-CPGs). Canada. A total of 119 paramedics completed an AD knowledge test and measures of attitudes, perceived control, self-efficacy, social pressure from patients and health-care professionals, and intentions to use the AD-CPGs before and 1 week, 3 months and 6 months after viewing 'ABCs of AD'. There were significant improvements in AD knowledge, attitudes and social pressure from patients to use the AD-CPGs from baseline to 1 week, 3 months and 6 months post viewing (all P<0.001). Self-efficacy and intentions increased 1 week post viewing (P<0.001), but returned to baseline levels at 3 and 6 months (P>0.05). There was no change in perceived control or social pressure from health-care professionals. AD knowledge and beliefs explained 50-61% of the variance in intentions to use the AD-CPGs. Attitudes, social pressure from patients and perceived behavioural control were significant unique predictors of intentions at all time points (P<0.05); AD knowledge was a significant predictor at 6 months only (P=0.048). No other predictors were significant. 'ABCs of AD' has immediate and sustained effects on paramedics' knowledge of attitudes toward and perceived pressure from patients to use the AD-CPGs. Updates to paramedic patient care guidelines and standards are needed to increase paramedics' perceived control and self-efficacy to implement the guidelines, and their intentions to use the AD-CPGs.

Transforming clinical practice guidelines and clinical pathways into fast-and-frugal decision trees to improve clinical care strategies.

PubMed

Djulbegovic, Benjamin; Hozo, Iztok; Dale, William

2018-02-27

Contemporary delivery of health care is inappropriate in many ways, largely due to suboptimal Q5 decision-making. A typical approach to improve practitioners' decision-making is to develop evidence-based clinical practice guidelines (CPG) by guidelines panels, who are instructed to use their judgments to derive practice recommendations. However, mechanisms for the formulation of guideline judgments remains a "black-box" operation-a process with defined inputs and outputs but without sufficient knowledge of its internal workings. Increased explicitness and transparency in the process can be achieved by implementing CPG as clinical pathways (CPs) (also known as clinical algorithms or flow-charts). However, clinical recommendations thus derived are typically ad hoc and developed by experts in a theory-free environment. As any recommendation can be right (true positive or negative), or wrong (false positive or negative), the lack of theoretical structure precludes the quantitative assessment of the management strategies recommended by CPGs/CPs. To realize the full potential of CPGs/CPs, they need to be placed on more solid theoretical grounds. We believe this potential can be best realized by converting CPGs/CPs within the heuristic theory of decision-making, often implemented as fast-and-frugal (FFT) decision trees. This is possible because FFT heuristic strategy of decision-making can be linked to signal detection theory, evidence accumulation theory, and a threshold model of decision-making, which, in turn, allows quantitative analysis of the accuracy of clinical management strategies. Fast-and-frugal provides a simple and transparent, yet solid and robust, methodological framework connecting decision science to clinical care, a sorely needed missing link between CPGs/CPs and patient outcomes. We therefore advocate that all guidelines panels express their recommendations as CPs, which in turn should be converted into FFTs to guide clinical care. © 2018 John Wiley & Sons, Ltd.

Background Conflict of interest (COI) of clinical practice guideline (CPG) sponsors and authors is an important potential source of bias in CPG development. The objectives of this study were to describe the COI policies for organizations currently producing a significant number of CPGs, and to determine if these policies meet 2011 Institute of Medicine (IOM) standards. Methodology/Principal Findings We identified organizations with five or more guidelines listed in the National Guideline Clearinghouse between January 1, 2009 and November 5, 2010. We obtained the COI policy for each organization from publicly accessible sources, most often the organization's website, and compared those polices to IOM standards related to COI. 37 organizations fulfilled our inclusion criteria, of which 17 (46%) had a COI policy directly related to CPGs. These COI policies varied widely with respect to types of COI addressed, from whom disclosures were collected, monetary thresholds for disclosure, approaches to management, and updating requirements. Not one organization's policy adhered to all seven of the IOM standards that were examined, and nine organizations did not meet a single one of the standards. Conclusions/Significance COI policies among organizations producing a large number of CPGs currently do not measure up to IOM standards related to COI disclosure and management. CPG developers need to make significant improvements in these policies and their implementation in order to optimize the quality and credibility of their guidelines. PMID:22629391

Evidence-based medicine, clinical practice guidelines, and common sense in the management of osteoporosis.

PubMed

Lewiecki, E Michael; Binkley, Neil

2009-01-01

To evaluate the benefits and limitations of randomized controlled trials (RCTs), clinical practice guidelines (CPGs), and clinical judgment in the management of osteoporosis. A review was conducted of the English-language literature on the origins and applications of RCTs, CPGs, evidence-based medicine, and clinical judgment in the management of osteoporosis. Evidence-based medicine is use of the currently available best evidence in making clinical decisions for individual patients. CPGs are recommendations for making clinical decisions based on research evidence, sometimes with consideration of expert opinion, health care policy, and costs of care. The highest levels of medical evidence are usually thought to be RCTs and meta-analyses of high-quality RCTs. Although it is desirable and appropriate for clinicians to consider research evidence from RCTs and recommendations presented in CPGs in making clinical decisions, other factors-such as patient preference, comorbidities, affordability, and availability of care-are important for the actual implementation of evidence-based medicine. Decisions about who to treat, which drug to use, how best to monitor, and how long to treat require clinical skills in addition to knowledge of medical research. The necessity of integrating common sense and clinical judgment is highlighted by the fact that many patients treated for osteoporosis in clinical practice would not qualify for participation in the pivotal clinical trials that demonstrated efficacy and safety of the drugs used to treat them.

Purpose: To customize clinical practice guidelines (CPGs) for cataract management in the Iranian population. Methods: First, four CPGs (American Academy of Ophthalmology 2006 and 2011, Royal College of Ophthalmologists 2010, and Canadian Ophthalmological Society 2008) were selected from a number of available CPGs in the literature for cataract management. All recommendations of these guidelines, together with their references, were studied. Each recommendation was summarized in 4 tables. The first table showed the recommendation itself in clinical question components format along with its level of evidence. The second table contained structured abstracts of supporting articles related to the clinical question with their levels of evidence. The third table included the customized recommendation of the internal group respecting its clinical advantage, cost, and complications. In the fourth table, the internal group their recommendations from 1 to 9 based on the customizing capability of the recommendation (applicability, acceptability, external validity). Finally, customized recommendations were sent one month prior to a consensus session to faculty members of all universities across the country asking for their comments on recommendations. Results: The agreed recommendations were accepted as conclusive while those with no agreement were discussed at the consensus session. Finally, all customized recommendations were codified as 80 recommendations along with their sources and levels of evidence for the Iranian population. Conclusion: Customization of CPGs for management of adult cataract for the Iranian population seems to be useful for standardization of referral, diagnosis and treatment of patients. PMID:27051491

Numerous scientific organisations have developed evidence-based recommendations aiming to optimise the management of osteoarthritis (OA). Uptake, however, has been suboptimal. The purpose of this exercise was to harmonize the recent recommendations and develop a user-friendly treatment algorithm to facilitate translation of evidence into practice. We updated a previous systematic review on clinical practice guidelines (CPGs) for OA management. The guidelines were assessed using the Appraisal of Guidelines for Research and Evaluation for quality and the standards for developing trustworthy CPGs as established by the National Academy of Medicine (NAM). Four case scenarios and algorithms were developed by consensus of a multidisciplinary panel. Sixteen guidelines were included in the systematic review. Most recommendations were directed toward physicians and allied health professionals, and most had multi-disciplinary input. Analysis for trustworthiness suggests that many guidelines still present a lack of transparency. A treatment algorithm was developed for each case scenario advised by recommendations from guidelines and based on panel consensus. Strategies to facilitate the implementation of guidelines in clinical practice are necessary. The algorithms proposed are examples of how to apply recommendations in the clinical context, helping the clinician to visualise the patient flow and timing of different treatment modalities.

Implementation of prophylaxis for venous thomboembolism (VTE) through risk assessment based on clinical practice guidelines (CPGs) is variably adopted in long term care facilities (LTCF). Current guidelines recommend venous thromboembolism prophylaxis (VTE-P) following risk assessment, individualized to patient status. In LTCF, differing comorbidity, life-expectancy, ethical, and quality-of-life issues may warrant a unique approach. This article examines VTE-P practices in LTCF before and after educational intervention to bring practice patterns consistent with CPGs. Phase 1 (preceding article in this issue) identified current practice to assess risk and implement VTE-P (17 geographically diverse LTCFs, 3260 total beds). Phase 2 (educational intervention using CPGs) and Phase 3 (outcomes) reexamined VTE-P at the same 17 centers. The frequency of indications for VTE-P and contraindications to anticoagulation were similar during Phases 1 and 3 (all P > .05). In Phase 3, use of aspirin alone decreased more than 50% (P < .0005), whereas use of compression devices increased (P < .0005). Regression models predicted no relationship between any indication or contraindication and VTE-P in Phase 1 (all P > .05) but identified significant relationships between indication and contraindications and VTE-P in Phase 3 (P = .022 to P < .0005), suggesting adequate understanding of current CPGs following education as the basis for improved VTE-P. The study confirms the presence of significant comorbidity in LTC residents, many with indications for VTE-P, some with contraindications for anticoagulation. Following educational intervention, more residents received VTE-P, influenced by risk-benefit ratio favoring treatment. These findings suggest that even a modest educational intervention significantly improves provider knowledge pertinent to risk assessment consistent with CPG and more appropriate VTE-P.

Methods Thirty-four paramedic and nurse trainees from two training programs in Canada completed measures immediately before and after viewing the online “ABCs of AD” module. Outcome measures AD knowledge test; Theory of Planned Behavior social cognition questionnaire; module feedback survey. Results Paired samples t-tests revealed significant increases in participants’ AD knowledge test scores (M ± SDpre = 9.00 ± 2.46, M ± SDpost = 12.03 ± 4.07, P < 0.001; d = 0.84). Prior to viewing the module, participants reported positive social cognitions for using the AD-CPGs (all Ms ≥ 4.84 out of 7). From pre- to post-module, no significant changes were seen in participants’ social cognitions for using the AD-CPGs. Participants’ average module viewing time was 36.73 ± 24.17 minutes (range 8–90 minutes). There was a decline in viewing from the first to the last module sections, with only half of participants viewing all six sections. Conclusion Knowledge alone is insufficient for clinical behavior change; as such, social cognitive determinants of behavior should be explicitly targeted in future iterations of the module to increase the likelihood of increased use of the AD-CPGs. To engage viewers across all module sections, the “ABCs of AD” module should include supplementary learning strategies, such as interactive quizzes and peer-to-peer interaction. PMID:25055849

We propose a new method to mitigate (identify and address) adverse interactions (drug-drug or drug-disease) that occur when a patient with comorbid diseases is managed according to two concurrently applied clinical practice guidelines (CPGs). A lack of methods to facilitate the concurrent application of CPGs severely limits their use in clinical practice and the development of such methods is one of the grand challenges for clinical decision support. The proposed method responds to this challenge. We introduce and formally define logical models of CPGs and other related concepts, and develop the mitigation algorithm that operates on these concepts. In the algorithm we combine domain knowledge encoded as interaction and revision operators using the constraint logic programming (CLP) paradigm. The operators characterize adverse interactions and describe revisions to logical models required to address these interactions, while CLP allows us to efficiently solve the logical models - a solution represents a feasible therapy that may be safely applied to a patient. The mitigation algorithm accepts two CPGs and available (likely incomplete) patient information. It reports whether mitigation has been successful or not, and on success it gives a feasible therapy and points at identified interactions (if any) together with the revisions that address them. Thus, we consider the mitigation algorithm as an alerting tool to support a physician in the concurrent application of CPGs that can be implemented as a component of a clinical decision support system. We illustrate our method in the context of two clinical scenarios involving a patient with duodenal ulcer who experiences an episode of transient ischemic attack. Copyright © 2013 Elsevier Inc.

Pressure ulcers are a serious complication for people with spinal cord injury (SCI). The Consortium for Spinal Cord Medicine (CSCM) published clinical practice guidelines (CPGs) that provided guidance for pressure ulcer prevention and treatment after SCI. The aim of this study was to assess providers' perceptions for each of the 32 CPG recommendations regarding their agreement with CPGs, degree of CPG implementation, and CPG implementation barriers and facilitators. This descriptive mixed-methods study included both qualitative (focus groups) and quantitative (survey) data collection approaches. The sample (n = 60) included 24 physicians and 36 nurses who attended the 2004 annual national conferences of the American Paraplegia Society or American Association of Spinal Cord Injury Nurses. This sample drew from two sources: a purposive sample from a list of preregistered participants and a convenience sample of conference attendee volunteers. We analyzed quantitative data using descriptive statistics and qualitative data using a coding scheme to capture barriers and facilitators. The focus groups agreed unanimously on the substance of 6 of the 32 recommendations. Nurse and physician focus groups disagreed on the degree of CGP implementation at their sites, with nurses as a group perceiving less progress in implementation of the guideline recommendations. The focus groups identified only one recommendation, complications of surgery, as being fully implemented at their sites. Categories of barriers and facilitators for implementation of CPGs that emerged from the qualitative analysis included (a) characteristics of CPGs: need for research/evidence, (b) characteristics of CPGs: complexity of design and wording, (c) organizational factors, (d) lack of knowledge, and (e) lack of resources. Although generally SCI physicians and nurses agreed with the CPG recommendations as written, they did not feel these recommendations were fully implemented in their respective clinical settings. The focus groups identified multiple barriers to the implementation of the CPGs and suggested several facilitators/solutions to improve implementation of these guidelines in SCI. Participants identified organizational factors and the lack of knowledge as the most substantial systems/issues that created barriers to CPG implementation.

Good-quality clinical practice guidelines (CPGs) provide recommendations based on current best-evidence summaries. Hypertension is a prevalent noncommunicable disease in Africa, with disastrous sequelae (stroke, heart, and kidney disease). Its effective management relies on good quality, current, locally relevant evidence. This paper reports on an all African review of the guidance documents currently informing hypertension management. Attempts were made to contact 62 African countries for formal guidance documents used nationally to inform diagnosis and management of hypertension. Their quality was assessed by using Appraisal of Guidelines for Research & Evaluation (AGREE) II, scored by 2 independent reviewers. Differences in domain scores were compared between documents written prior to 2011 and 2011 onward. Findings were compared with earlier African CPG reviews. Guidelines and protocols were provided by 26 countries. Six used country-specific stand-alone hypertension guidelines, and 10 used protocols embedded in Standard Treatment Guidelines for multiple conditions. Six used guidelines developed by the World Health Organization, and 4 indicated ad hoc use of international guidance (US, Portugal, and Brazil). Only 1 guidance document met CPG construction criteria, and none scored well on all AGREE domain scores. The lowest-scoring domain was rigour of development. There was no significant quality difference between pre-2011 and post-2011 guidance documents, and there were variable AGREE II scores for the same CPGs when comparing the African reviews. The quality of hypertension guidance used by African nations could be improved. The need for so many guidance documents is questioned. Adopting a common evidence base from international good-quality CPGs and layering it with local contexts offer 1 way to efficiently improve African hypertension CPG quality and implementation. © 2018 John Wiley & Sons, Ltd.

Developing computer-interpretable clinical practice guidelines (CPGs) to provide decision support for guideline-based care is an extremely labor-intensive task. In the EON/ATHENA and SAGE projects, we formulated substantial portions of CPGs as computable statements that express declarative relationships between patient conditions and possible interventions. We developed query and expression languages that allow a decision-support system (DSS) to evaluate these statements in specific patient situations. A DSS can use these guideline statements in multiple ways, including: (1) as inputs for determining preferred alternatives in decision-making, and (2) as a way to provide targeted commentaries in the clinical information system. The use of these declarative statements significantly reduces the modeling expertise and effort required to create and maintain computer-interpretable knowledge bases for decision-support purpose. We discuss possible implications for sharing of such knowledge bases.

Aligning Documentation With Congenital Muscular Torticollis Clinical Practice Guidelines: Administrative Case Report.

2016-01-01

A hospital-based pediatric outpatient center, wanting to weave evidence into practice, initiated an update of knowledge, skills, and documentation patterns with its staff physical therapists and occupational therapists who treat people with congenital muscular torticollis (CMT). This case report describes 2 cycles of implementation: (1) the facilitators and barriers to implementation and (2) selected quality improvement outcomes aligned with published clinical practice guidelines (CPGs). The Pediatric Therapy Services of St Joseph's Regional Medical Center in New Jersey has 4 full-time, 1 part-time, and 3 per diem staff. Chart audits in 2012 revealed variations in measurement, interventions, and documentation that led to quality improvement initiatives. An iterative process, loosely following the knowledge-to-action cycle, included a series of in-service training sessions to review the basic anatomy, pathokinesiology, and treatment strategies for CMT; reading assignments of the available CPGs; journal review; documentation revisions; and training on the recommended measurements to implement 2 published CPGs and measure outcomes. A previous 1-page generic narrative became a 3-page CMT-specific form aligned with the American Physical Therapy Association Section on Pediatrics CMT CPG recommendations. Staff training on the Face, Legs, Activity, Cry, Consolability (FLACC) pain scale, classification of severity, type of CMT, prognostication, measures of cervical range of motion, and developmental progression improved documentation consistency from 0% to 81.9% to 100%. Clinicians responded positively to using the longer initial evaluation form. Successful implementation of both clinical and documentation practices were facilitated by a multifaceted approach to knowledge translation that included a culture supportive of evidence-based practice, administrative support for training and documentation redesign, commitment by clinicians to embrace changes aimed at improved care, and clinical guidelines that provide implementable recommendations. © 2016 American Physical Therapy Association.

With the rising efforts to guarantee a high quality treatment in medicine and to reduce the costs in the health care system, Clinical Practice Guidelines (CPG) have developed into a very important reference in medicine. CPGs are especially useful for the standardization of multi-professional treatment processes like the care for patients with malignant diseases. The Tumour-Centre Heidelberg/Mannheim (Germany) leads a project to build up a regional, virtual distributed Electronic Patient Record (EPR) for patients with malignant diseases in the Rhein-Neckar-Area. Aims of the first stages of the project are the introduction of the distributed EPR to two co-operating pilot-clinics. In this context we intend to provide access for medical professionals not only to the data of the jointly treated patients, but also to relevant existing CPGs and other medical knowledge sources like Medline and Cochrane-Library. Knowledge and Patient data should be interlinked to offer patient-specific views on the CPG-information. As all professions have different information needs, this views should be presented individualized according to the demands of the users. We analysed three relevant CPGs and defined a meta-structure that will be refined to a common meta-structure for CPGs in Oncology. CPGs as well as structured patient-documents will be implemented in the Extensible Markup Language (XML), as this platform-independent technology seems to suit our needs for data exchange and presentation purposes best. The implementation process will be accompanied tightly with evaluations to gain experience for further expansions of the EPR. The vision of the project is, that by integrating CPGs in a shared distributed EPR, the way towards standardized treatment processes in a local, but multi-professional setting, and the efforts to guarantee a high quality treatment in Oncology can sufficiently be supported.

Little is known about allied health (AH) clinical practice guideline (CPG) activity in South Africa, and particularly in relation to primary health care (PHC). This paper reports on a scoping study undertaken to establish a reference framework, from which a comprehensive maximum variation sample could be selected. This was required to underpin robust sampling for a qualitative study aimed at understanding South African primary care AH therapy CPG activities. This paper builds on findings from the South African Guidelines Evaluation (Project SAGE) Flagship grant. South African government websites were searched for structures of departments and portfolios, and available CPGs. Professional AH association websites were searched for CPGs, purposively-identified key informants were interviewed, and CPGs previously identified for priority South African primary care conditions were critiqued for AH therapy involvement. Key informants described potentially complex relationships between players who may be engaged in South African AH CPGs, in both public and private sectors. There were disability/rehabilitation portfolios at national and provincial governments, but no uniformity in provincial government organisation of, or support for, PHC AH services. There were no AH primary care therapy CPGs on government websites, although there was 'clinical guidance' in various forms on professional association websites. Only two CPGs of priority South African PHC conditions included mention of any AH therapy (physiotherapy for adult asthma and chronic obstructive pulmonary disease). A comprehensive and wide-reaching stakeholder reference framework would be required in order to capture the heterogeneity of AH primary care CPG activity in South Africa. This should involve the voices of national and purposively-selected provincial governments, academic institutions, consultants, public sector managers and clinicians, private practitioners, professional associations, and private sector insurers. Provincial governments should be selected to reflect heterogeneity in local economics, population demographics and availability of university AH training programs. This investigation should aim to determine the areas of PHC in which AH are engaged.

Health care professionals (HCPs) are able to make effective decisions regarding patient care through the use of systematically developed clinical practice guidelines (CPGs). These recommendations are especially important in a cancer health care context as patients are exposed to a multitude of interdisciplinary HCPs offering high-quality care throughout diagnosis, treatment, survivorship and palliative care. Although a large number of CPGs targeted towards cancer are widely disseminated, it is unknown whether implementation strategies targeting the use of these guidelines are effective in effecting HCP behaviour and patient outcomes in the cancer care context. The purpose of this systematic review will be to determine the effectiveness of different CPG dissemination and implementation interventions on HCPs' behaviour and patient outcomes in the cancer health care context. Five electronic databases (CINAHL, the Cochrane Controlled Trials Register, MEDLINE via Ovid, EMBASE via Ovid and PsycINFO via Ovid) will be searched to include all studies examining the dissemination and/or implementation of CPGs in a cancer care setting targeting all HCPs. CPG implementation strategies will be included if the CPGs were systematically developed (e.g. literature review/evidence-informed, expert panel, evidence appraisal). The studies will be limited to randomized controlled trials, controlled clinical trials and quasi-experimental (interrupted time series, controlled before-and-after designs) studies. Two independent reviewers will assess articles for eligibility, data extraction and quality appraisal. The aim of this review is to inform cancer care health care professionals and policymakers about evidence-based implementation strategies that will allow for effective use of CPGs.

Bridging the gap between clinical research and everyday health-care practice requires effective communication strategies. To address current shortcomings in conveying practice recommendations and supporting evidence, we are creating and testing presentation formats for clinical practice guidelines (CPGs). We carried out multiple cycles of brainstorming and sketching, developing a prototype. Physicians participating in the user testing viewed CPG formats linked to clinical scenarios and engaged in semistructured interviews applying a think-aloud method for exploring important aspects of user experience. We developed a multilayered presentation format that allows clinicians to successively view more in-depth information. Starting with the recommendations, clinicians can, on demand, access a rationale and a key information section containing statements on quality of the evidence, balance between desirable and undesirable consequences, values and preferences, and resource considerations. We collected feedback from 27 stakeholders and performed user testing with 47 practicing physicians from six countries. Advisory group feedback and user testing of the first version revealed problems with conceptual understanding of underlying CPG methodology, as well as difficulties with the complexity of the layout and content. Extensive revisions made before the second round of user testing resulted in most participants expressing overall satisfaction with the final presentation format. We have developed an electronic, multilayered, CPG format that enhances the usability of CPGs for frontline clinicians. We have implemented the format in electronic guideline tools that guideline organizations can now use when authoring and publishing their guidelines.

Objectives: To identify Canadian chiropractors’ attitudes, skills and use of evidence based practice (EBP), as well as their level of awareness of previously published chiropractic clinical practice guidelines (CPGs). Methods: 7,200 members of the Canadian Chiropractic Association were invited by e-mail to complete an online version of the Evidence Based practice Attitude & utilisation SurvEy (EBASE); a valid and reliable measure of participant attitudes, skills and use of EBP. Results: Questionnaires were completed by 554 respondents. Most respondents (>75%) held positive attitudes toward EBP. Over half indicated a high level of self-reported skills in EBP, and over 90% expressed an interest in improving these skills. A majority of respondents (65%) reported over half of their practice was based on evidence from clinical research, and only half (52%) agreed that chiropractic CPGs significantly impacted on their practice. Conclusions: While most Canadian chiropractors held positive attitudes towards EBP, believed EBP was useful, and were interested in improving their skills in EBP, many did not use research evidence or CPGs to guide clinical decision making. Our findings should be interpreted cautiously due to the low response rate. PMID:26816412

Implementation of WHO case management guidelines for serious common childhood illnesses remains a challenge in hospitals in low-income countries. The impact of locally adapted clinical practice guidelines (CPGs) on the quality-of-care of patients in tertiary hospitals has rarely been evaluated. We conducted, in Kenyatta National Hospital, an uncontrolled before and after study with an attempt to explore intervention dose-effect relationships, as CPGs were disseminated and training was progressively implemented. The emergency triage, assessment and treatment plus admission care (ETAT+) training and locally adapted CPGs targeted common, serious childhood illnesses. We compared performance in the pre-intervention (2005) and post-intervention periods (2009) using quality indicators for three diseases: pneumonia, dehydration and severe malnutrition. The indicators spanned four domains in the continuum of care namely assessment, classification, treatment, and follow-up care in the initial 48 hours of admission. In the pre-intervention period patients' care was largely inconsistent with the guidelines, with nine of the 15 key indicators having performance of below 10%. The intervention produced a marked improvement in guideline adherence with an absolute effect size of over 20% observed in seven of the 15 key indicators; three of which had an effect size of over 50%. However, for all the five indicators that required sustained team effort performance continued to be poor, at less than 10%, in the post-intervention period. Data from the five-year period (2005-09) suggest some dose dependency though the adoption rate of the best-practices varied across diseases and over time. Active dissemination of locally adapted clinical guidelines for common serious childhood illnesses can achieve a significant impact on documented clinical practices, particularly for tasks that rely on competence of individual clinicians. However, more attention must be given to broader implementation strategies that also target institutional and organisational aspects of service delivery to further enhance quality-of-care.

ABSTRACT Purpose: In this study, we characterized physiotherapists' attitudes and beliefs about the bio-psychosocial problem of low back pain (LBP), their use of clinical practice guidelines (CPGs), and the extent to which their advice and treatment is in line with best-evidence CPGs. Methods: One hundred eight physiotherapists completed an online survey that included questionnaires exploring the strength of physiotherapists' biomedical and bio-psychosocial orientations toward the management of LBP: the Pain Attitudes and Beliefs Scale for Physiotherapists and the Attitudes to Back Pain Scale for musculoskeletal practitioners. In addition, participants responded to questions about treatment recommendations for patients in two vignettes. Results: Only 12% of respondents were aware of CPGs. Physiotherapists with a stronger biomedical orientation scored the severity of spinal pathology higher in the patient vignettes. A stronger biomedical orientation was also associated with disagreement with recommendations to return to usual activity or work. Conclusions: The results suggest limited awareness by physiotherapists of best-evidence CPGs and contemporary understandings of LBP that support early activation and self-management. Research to better understand and facilitate the implementation of best-evidence professional education and clinical practice is an urgent priority. PMID:22942525

An Algorithm Using Twelve Properties of Antibiotics to Find the Recommended Antibiotics, as in CPGs.

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

Background/Objectives: Clinical Practice Guidelines (CPGs) have been published on a number of topics in spinal cord injury (SCI) medicine. Research in the general medical literature shows that the distribution of CPGs has a minimal effect on physician practice without targeted implementation strategies. The purpose of this study was to determine (a) whether dissemination of an SCI CPG improved the likelihood that patients would receive CPG recommended care and (b) whether adherence to CPG recommendations could be improved through a targeted implementation strategy. Specifically, this study addressed the “Neurogenic Bowel Management in Adults with Spinal Cord Injury” Clinical Practice Guideline published in March 1998 by the Consortium for Spinal Cord Medicine Methods: CPG adherence was determined from medical record review at 6 Veterans Affairs SCI centers for 3 time periods: before guideline publication (T1), after guideline publication but before CPG implementation (T2), and after targeted CPG implementation (T3). Specific implementation strategies to enhance guideline adherence were chosen to address the barriers identified by SCI providers in focus groups before the intervention. Results: Overall adherence to recommendations related to neurogenic bowel did not change between T1 and T2 (P = not significant) but increased significantly between T2 and T3 (P < 0.001) for 3 of 6 guideline recommendations. For the other 3 guideline recommendations, adherence rates were noted to be high at T1. Conclusions: While publication of the CPG alone did not alter rates of provider adherence, the use of a targeted implementation plan resulted in increases in adherence rates with some (3 of 6) CPG recommendations for neurogenic bowel management.

To analyze characteristics of clinical practice guidelines (CPGs) for the management of rheumatoid arthritis (RA) developed in Latin American (LA) countries and to describe the knowledge, use, and barriers for their implementation perceived among LA rheumatologists, a comprehensive literature search including Medline, PubMed, Cochrane Library, LILACS and Scielo was performed. The Appraisal of Guidelines for Research and Evaluation (AGREE) instrument was applied for evaluation. A survey was sent to PANLAR members containing questions related to knowledge about guidelines, application of the recommendations, and difficulties in implementing CPGs. Eight guidelines were identified. Most guidelines were evidence based (62 %), but in only 37 % a systematic literature search was done. None of the guidelines included patients' views and preferences, and only few of them stated an updating procedure. Funding body independence and disclosure of conflicts of interest were rarely reported. The survey was answered by 214 rheumatologists from all Latin American countries. Most rheumatologist reported knowledge and use of clinical guidelines, mainly international ones. In general, rheumatologist felt that guidelines apply to only a minority of patients seen in daily clinical practice. Limited access expensive drugs, suggested by the guidelines, was the most frequent barrier to guidelines implementation that was reported. A good number of guidelines on the treatment of rheumatoid arthritis have been developed in Latin America. Most of them are lacking some of the components recognized for high-quality clinical guidelines development. In spite that most rheumatologist know and apply guidelines, access to drugs is still a very important barrier to their implementation in Latin America.

Systematic and transparent inclusion of ethical issues and recommendations in clinical practice guidelines: a six-step approach.

PubMed

Mertz, Marcel; Strech, Daniel

2014-12-04

Clinical practice guidelines (CPGs), a core tool to foster medical professionalism, differ widely in whether and how they address disease-specific ethical issues (DSEIs), and current manuals for CPG development are silent on this issue. The implementation of an explicit method faces two core challenges: first, it adds further complexity to CPG development and requires human and financial resources. Second, in contrast to the in-depth treatment of ethical issues that is standard in bioethics, the inclusion of DSEIs in CPGs need to be more pragmatic, reductive, and simplistic, but without rendering the resulting recommendations useless or insufficiently justified. This paper outlines a six-step approach, EthicsGuide, for the systematic and transparent inclusion of ethical issues and recommendations in CPGs. The development of EthicsGuide is based on (a) methodological standards in evidence-based CPG development, (b) principles of bioethics, (c) research findings on how DSEIs are currently addressed in CPGs, and (d) findings from two proof-of-concept analyses of the EthicsGuide approach. The six steps are 1) determine the DSEI spectrum and the need for ethical recommendations; 2) develop statements on which to base ethical recommendations; 3) categorize, classify, condense, and paraphrase the statements; 4) write recommendations in a standard form; 5) validate and justify recommendations, making any necessary modifications; and 6) address consent. All six steps necessarily come into play when including DSEIs in CPGs. If DSEIs are not explicitly addressed, they are unavoidably dealt with implicitly. We believe that as ethicists gain greater involvement in decision-making about health, personal rights, or economic issues, they should make their methods transparent and replicable by other researchers; and as ethical issues become more widely reflected in CPGs, CPG developers have to learn how to address them in a methodologically adequate way. The approach proposed should serve as a basis for further discussion on how to reach these goals. It breaks open the black box of what ethicists implicitly do when they develop recommendations. Further, interdisciplinary discussion and pilot tests are needed to explore the minimal requirements that guarantee a simplified procedure which is still acceptable and does not become mere window dressing.

Comparing Drug-Disease Associations in Clinical Practice Guideline Recommendations and Drug Product Label Indications.

Leung, Tiffany I; Dumontier, Michel

2015-01-01

Clinical practice guidelines (CPGs) and structured product labels (SPLs) are both intended to promote evidence-based medical practices and guide clinicians' prescribing decisions. However, it is unclear how well CPG recommendations about pharmacologic therapies for certain diseases match SPL indications for recommended drugs. In this study, we use publicly available data and text mining methods to examine drug-disease associations in CPG recommendations and SPL treatment indications for 15 common chronic conditions. Preliminary results suggest that there is a mismatch between guideline-recommended pharmacologic therapies and SPL indications. Conflicting or inconsistent recommendations and indications may complicate clinical decision making and implementation or measurement of best practices.

Objective Tympanostomy tube (TT) insertion is the most common ambulatory surgery performed on children. American Academy of Otolaryngology-Head and Neck Surgery Founda-tion (AAO-HNSF) Clinical Practice Guidelines (CPGs) recommend hearing testing for all pediatric TT candidates. The aim of this study was to assess audiometric testing in this population. Study Design Retrospective population-based cohort study. Setting All hospitals in the Canadian province of Ontario. Subjects and Methods All patients 12 years of age and younger who underwent at least 1 TT procedure between January 1993 and June 2016. The primary outcomes were the percentage of patients who underwent a hearing test within 1 year before and/or 1 year after surgery. Results A total of 316,599 bilateral TT procedures were performed during the study period (1993 to 2016). Presurgical hearing tests increased from 55.7% to 74.9%, and postsurgical hearing tests increased from 42.2% to 68.9%. Younger surgeons demonstrated a greater adherence to the CPGs (relative risk [RR], 1.22; 95% CI, 1.08-1.38; P = .001). Remarkably, there was not a spike in preoperative hearing tests following the introduction of the CPGs in 2013 (RR, 1.12; 95% CI, 0.85-1.47; P = .432). Presurgical hearing testing ranged from 26.1% to 83.5% across health regions. Conclusion In this cohort of children who underwent TT placement, the trends of preoperative and postoperative audiometric testing are increasing but are still lower than recommended by the CPGs, despite a tripling of practicing audiologists. This study describes the current state of testing in Ontario and highlights issues of access to audiology services, possible parent preferences, and the importance of ongoing continuing medical education for all health care practitioners.

Clinical practice guideline (CPG) activities must be planned carefully for efficient use of available resources and evidence-based implementation. De novo development of CPGs may sometimes 'recreate the wheel' and delay implementation. Three innovative alternatives to de novo CPG development (adopt, contextualise or adapt) are outlined, which have greater potential than de novo development to best use the limited available resources, personnel and time in settings such as South Africa.

Background The Department of Veterans Affairs (VA) mandated the system-wide implementation of clinical practice guidelines (CPGs) in the mid-1990s, arming all facilities with basic resources to facilitate implementation; despite this resource allocation, significant variability still exists across VA facilities in implementation success. Objective This study compares CPG implementation strategy patterns used by high and low performing primary care clinics in the VA. Research Design Descriptive, cross-sectional study of a purposeful sample of six Veterans Affairs Medical Centers (VAMCs) with high and low performance on six CPGs. Subjects One hundred and two employees (management, quality improvement, clinic personnel) involved with guideline implementation at each VAMC primary care clinic. Measures Participants reported specific strategies used by their facility to implement guidelines in 1-hour semi-structured interviews. Facilities were classified as high or low performers based on their guideline adherence scores calculated through independently conducted chart reviews. Findings High performing facilities (HPFs) (a) invested significantly in the implementation of the electronic medical record and locally adapting it to provider needs, (b) invested dedicated resources to guideline-related initiatives, and (c) exhibited a clear direction in their strategy choices. Low performing facilities exhibited (a) earlier stages of development for their electronic medical record, (b) reliance on preexisting resources for guideline implementation, with little local adaptation, and (c) no clear direction in their strategy choices. Conclusion A multifaceted, yet targeted, strategic approach to guideline implementation emphasizing dedicated resources and local adaptation may result in more successful implementation and higher guideline adherence than relying on standardized resources and taxing preexisting channels.

Stress urinary incontinence (SUI) is the most common form of incontinence impacting on quality of life (QOL) and is associated with high financial, social, and emotional costs. The purpose of this study was to provide an update existing Dutch evidence-based clinical practice guidelines (CPGs) for physiotherapy management of patients with stress urinary incontinence (SUI) in order to support physiotherapists in decision making and improving efficacy and uniformity of care. A computerized literature search of relevant databases was performed to search for information regarding etiology, prognosis, and physiotherapy assessment and management in patients with SUI. Where no evidence was available, recommendations were based on consensus. Clinical application of CPGs and feasibility were reviewed. The diagnostic process consists of systematic history taking and physical examination supported by reliable and valid assessment tools to determine physiological potential for recovery. Therapy is related to different problem categories. SUI treatment is generally based on pelvic floor muscle exercises combined with patient education and counseling. An important strategy is to reduce prevalent SUI by reducing influencing risk factors. Scientific evidence supporting assessment and management of SUI is strong. The CPGs reflect the current state of knowledge of effective and tailor-made intervention in SUI patients.

Computerized Clinical Practice Guidelines (CPGs) improve quality of care by assisting physicians in their decision making. A number of problems emerges since patients with close characteristics are given contradictory recommendations. In this article, we propose to use fuzzy logic to model uncertainty due to the use of thresholds in CPGs. A fuzzy classification procedure has been developed that provides for each message of the CPG, a strength of recommendation that rates the appropriateness of the recommendation for the patient under consideration. This work is done in the context of a CPG for the diagnosis and the management of hypertension, published in 1997 by the French agency ANAES. A population of 82 patients with mild to moderate hypertension was selected and the results of the classification system were compared to whose given by a classical decision tree. Observed agreement is 86.6% and the variability of recommendations for patients with close characteristics is reduced. PMID:11825196

Although clinical-practice guidelines (CPGs) are implemented on the assumption that they will improve the quality, efficiency, and consistency of health care, they generally have limited effect in changing physicians' behavior. The purpose of this study was to design and implement an effective program for formulating, promulgating, and implementing CPGs to foster the development of an evidence-based culture in an Israeli HMO. The authors implemented a four-stage program of stepwise collaborative efforts with academic institutions composed of developing quantitative tools to evaluate prescribing patterns, updating CPGs, collecting MDs' input via focus groups and quantitative surveys, and conducting a randomized controlled trial of a two-stage, multipronged intervention. The test case for this study was the development, dissemination, and implementation of CPG for the treatment of acute uncomplicated cystitis in adult women. Interventions in the form of a lecture at a conference and a letter with personalized feedback were implemented, both individually and combined, to improve physicians' rates of prescribing the first-line drug, nitrofurantoin, and, in the absence of nitrofurantoin, adhering to the recommended duration of three days of treatment with ofloxacin. The tools and data-generating capabilities designed and constructed in Stage I of the project were integral components of all subsequent stages of the program. Personalized feedback alone was sufficient to improve the rate of adherence to the guidelines by 19.4% (95% CI = 16.7, 22.1). This study provides a template for introducing the component of experimentation essential for cultivating an evidence-based culture. This process, composed of collaborative efforts between academic institutions and a managed care organization, may be beneficial to other health care systems.

Implementation of World Health Organization case management guidelines for serious childhood illnesses remains a challenge in hospitals in low-income countries. Facilitators of and barriers to implementation of locally adapted clinical practice guidelines (CPGs) have not been explored. This ethnographic study based on the theory of participatory action research (PAR) was conducted in Kenyatta National Hospital, Kenya's largest teaching hospital. The primary intervention consisted of dissemination of locally adapted CPGs. The PRECEDE-PROCEED health education model was used as the conceptual framework to guide and examine further reinforcement activities to improve the uptake of the CPGs. Activities focussed on introduction of routine clinical audits and tailored educational sessions. Data were collected by a participant observer who also facilitated the PAR over an eighteen-month period. Naturalistic inquiry was utilized to obtain information from all hospital staff encountered while theoretical sampling allowed in-depth exploration of emerging issues. Data were analysed using interpretive description. Relevance of the CPGs to routine work and emergence of a champion of change facilitated uptake of best-practices. Mobilization of basic resources was relatively easily undertaken while activities that required real intellectual and professional engagement of the senior staff were a challenge. Accomplishments of the PAR were largely with the passive rather than active involvement of the hospital management. Barriers to implementation of best-practices included i) mismatch between the hospital's vision and reality, ii) poor communication, iii) lack of objective mechanisms for monitoring and evaluating quality of clinical care, iv) limited capacity for planning strategic change, v) limited management skills to introduce and manage change, vi) hierarchical relationships, and vii) inadequate adaptation of the interventions to the local context. Educational interventions, often regarded as 'quick-fixes' to improve care in low-income countries, may be necessary but are unlikely to be sufficient to deliver improved services. We propose that an understanding of organizational issues that influence the behaviour of individual health professionals should guide and inform the implementation of best-practices.

Quality of clinical practice guidelines of lower extremity venous ulcers.

Rumbo-Prieto, José María; Arantón-Areosa, Luis; Palomar-Llatas, Federico; Romero-Martín, Manuel

The clinical variability and professional uncertainty in the prevention and treatment of lower extremity venous ulcers (VU) has as a main consequence, the fact that patients can be subjected to diagnostic and therapeutic tests, sometimes of dubious utility, these may even be harmful to the health of the patient and that, at other times, certain procedures or processes that may be appropriate to the patient's situation and needs may be omitted. It is for this reason that a series of specific documents called clinical practice guidelines for the approach of VU (CPG-VU) have been created, with the aim of improving the effectiveness and quality of care, reducing unjustified variability and establishing homogeneous criteria for its handling. Nevertheless, the literature shows that not all CPGs have the same methodological and evidence-drawing criteria. Many of them are of poor scientific quality and editorial rigor. This implies that CPGs should be periodically reviewed and updated based on the most current evidence and their quality contrasted with validated instruments such as AGREE-II. After an analysis of the quality of six CPG-VU available today, it has been possible to identify what guidelines are recommended for its implementation in the practice of care, which should be modified to improve their applicability and development of the evidence.

Comprehensive mitigation framework for concurrent application of multiple clinical practice guidelines.

PubMed

Wilk, Szymon; Michalowski, Martin; Michalowski, Wojtek; Rosu, Daniela; Carrier, Marc; Kezadri-Hamiaz, Mounira

2017-02-01

In this work we propose a comprehensive framework based on first-order logic (FOL) for mitigating (identifying and addressing) interactions between multiple clinical practice guidelines (CPGs) applied to a multi-morbid patient while also considering patient preferences related to the prescribed treatment. With this framework we respond to two fundamental challenges associated with clinical decision support: (1) concurrent application of multiple CPGs and (2) incorporation of patient preferences into the decision making process. We significantly expand our earlier research by (1) proposing a revised and improved mitigation-oriented representation of CPGs and secondary medical knowledge for addressing adverse interactions and incorporating patient preferences and (2) introducing a new mitigation algorithm. Specifically, actionable graphs representing CPGs allow for parallel and temporal activities (decisions and actions). Revision operators representing secondary medical knowledge support temporal interactions and complex revisions across multiple actionable graphs. The mitigation algorithm uses the actionable graphs, revision operators and available (and possibly incomplete) patient information represented in FOL. It relies on a depth-first search strategy to find a valid sequence of revisions and uses theorem proving and model finding techniques to identify applicable revision operators and to establish a management scenario for a given patient if one exists. The management scenario defines a safe (interaction-free) and preferred set of activities together with possible patient states. We illustrate the use of our framework with a clinical case study describing two patients who suffer from chronic kidney disease, hypertension, and atrial fibrillation, and who are managed according to CPGs for these diseases. While in this paper we are primarily concerned with the methodological aspects of mitigation, we also briefly discuss a high-level proof of concept implementation of the proposed framework in the form of a clinical decision support system (CDSS). The proposed mitigation CDSS "insulates" clinicians from the complexities of the FOL representations and provides semantically meaningful summaries of mitigation results. Ultimately we plan to implement the mitigation CDSS within our MET (Mobile Emergency Triage) decision support environment. Copyright © 2016 Elsevier Inc. All rights reserved.

Several societies have produced and disseminated clinical practice guidelines (CPGs) for the symptomatic management of fever in children. However, to date, the quality of such guidelines has not been appraised. To identify and evaluate guidelines for the symptomatic management of fever in children. The research was conducted using PubMed, guideline websites, and Google (January 2010 to July 2016). The quality of the CPGs was independently assessed by two assessors using the Appraisal of Guidelines for Research & Evaluation II (AGREE II) instrument, and specific recommendations in guidelines were summarised and evaluated. Domain scores were considered of sufficient quality when >60% and of good quality when >80%. Seven guidelines were retrieved. The median score for the scope and purpose domain was 85.3% (range 66.6-100%). The median score for the stakeholder involvement domain was 57.5% (range 33.3-83.3%) and four guidelines scored >60%. The median score for the rigour of development domain was 52.0% (range 14.6-98.9%), and only three guidelines scored >60%. The median score for the clarity of presentation domain was 80.9% (range 50.0-94.4%). The median score for the applicability domain was 39.3% (8.3-100%). Only one guideline scored >60%. The median score for the editorial independence domain was 48.84% (0-91.6%); only three guidelines scored >60%. Most guidelines were recommended for use even if with modification, especially in the methodology, the applicability and the editorial independence domains. Our results could help improve reporting of future guidelines, and affect the selection and use of guidelines in clinical practice. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

There is broad consensus that screening and diagnosis of permanent hearing loss in children must be embedded within a comprehensive, evidence-based, family-centered intervention program. Clinical practice guidelines (CPGs) for pediatric hearing assessment and hearing aid verification aim to reduce variability in practice and increase the use of effective evidence-based diagnostic and treatment options so that optimal outcomes may be achieved. To be of value, guidelines must be translated and implemented into practice and ongoing monitoring of their use in practice should occur. This paper provides the results of two studies that aim to examine current pediatric audiology and amplification practice in North America. A concurrent embedded mixed methods design was used. An electronic survey was distributed to North American audiologists who delivered pediatric audiology services with 350 audiologists participating in study 1 and 63 audiologists participating in study 2. A quantitative approach was the predominant method of data collection. Respondents were prompted to provide additional qualitative text and detail regarding their quantitative response choice. This qualitative text was used during the analysis phase and combined with quantitative results to assist understanding of respondents' knowledge, skills, and barriers/facilitators to implement best practice in pediatric amplification. Approximately 70% of audiologists reported using best-practice protocols for pediatric hearing aid fitting. Despite widespread knowledge and increased use of CPGs over the last 18 yrs, results of these studies show that variation in practice patterns continue to exist. Several examples of implementation challenges are discussed with recommendations provided. In order for audiologists working with children who are deaf or hard of hearing and their families to achieve the principles of family-centered early intervention, practice guidelines must continue to be developed, disseminated, and translated as they have a positive impact on the services provided. Researchers and clinical audiologists who deliver services must continue to collaborate to understand the "how" and "why" of implementing guidelines into practice and to identify the barriers/facilitators encountered in trying to do so.

2016-01-01

The purpose of this narrative inquiry was to explore the experiences of persons who were injured in traffic collisions and seek their recommendations for the development of clinical practice guideline (CPG) for the management of minor traffic injuries. Patients receiving care for traffic injuries were recruited from 4 clinics in Ontario, Canada resulting in 11 adult participants (5 men, 6 women). Eight were injured while driving cars, 1 was injured on a motorcycle, 2 were pedestrians, and none caused the collision. Using narrative inquiry methodology, initial interviews were audiotaped, and follow-up interviews were held within 2 weeks to extend the story of experience created from the first interview. Narrative plotlines across the 11 stories were identified, and a composite story inclusive of all recommendations was developed by the authors. The research findings and composite narrative were used to inform the CPG Expert Panel in the development of new CPGs. Four recommended directions were identified from the narrative inquiry process and applied. First, terminology that caused stigma was a concern. This resulted in modified language ("injured persons") being adopted by the Expert Panel, and a new nomenclature categorizing layers of injury was identified. Second, participants valued being engaged as partners with health care practitioners. This resulted in inclusion of shared decision-making as a foundational recommendation connecting CPGs and care planning. Third, emotional distress was recognized as a factor in recovery. Therefore, the importance of early detection and the ongoing evaluation of risk factors for delayed recovery were included in all CPGs. Fourth, participants shared that they were unfamiliar with the health care system and insurance industry before their accident. Thus, repeatedly orienting injured persons to the system was advised. A narrative inquiry of 11 patients' experiences with traffic collision and their recommendations for clinical guidelines informed the Ontario Protocol for Traffic Injury Management Collaboration in the development of new Minor Injury Guidelines. The values and findings of the qualitative inquiry were interwoven into each clinical pathway and embedded within the final guideline report submitted to government.

Clinical practice guidelines (CPGs) are common tools in policy and clinical practice informing clinical decisions at the bedside, governance of health facilities, health insurer and government spending, and patient choices. South Africa's health sector is transitioning to a national health insurance system, aiming to build on other primary health care initiatives to transform the previously segregated, inequitable services. Within these plans CPGs are an integral tool for delivering standardised and cost effective care. Currently, there is no accepted standard approach to developing, adapting or implementing CPGs efficiently or effectively in South Africa. We explored the current players; drivers; and the context and processes of primary care CPG development from the perspective of stakeholders operating at national level. We used a qualitative approach. Sampling was initially purposeful, followed by snowballing and further sampling to reach representivity of primary care service providers. Individual in-depth interviews were recorded and transcribed verbatim. We used thematic content analysis to analyse the data. We conducted 37 in-depth interviews from June 2014-July 2015. We found CPG development and implementation were hampered by lack of human and funding resources for technical and methodological work; fragmentation between groups, and between national and provincial health sectors; and lack of agreed systems for CPG development and implementation. Some CPG contributors steadfastly work to improve processes aiming to enhance communication, use of evidence, and transparency to ensure credible guidance is produced. Many interviewed had shared values, and were driven to address inequity, however, resource gaps were perceived to create an enabling environment for commercial interests or personal agendas to drive the CPG development process. Our findings identified strengths and gaps in CPG development processes, and a need for national standards to guide CPG development and implementation. Based on our findings and suggestions from participants, a possible way forward would be for South Africa to have a centrally coordinated CPG unit to address these needs and aspects of fragmentation by devising processes that support collaboration, transparency and credibility across sectors and disciplines. Such an initiative will require adequate resourcing to build capacity and ensure support for the delivery of high quality CPGs for South African primary care.

This article reviews the progress Canada has made integrating palliative care into oncologic practice. Key clinical practice guidelines (CPGs) have influenced and have been translated into Canadian oncology policy and operations. Comprehensive accreditation standards exist to guide oncology practice in institutional and ambulatory care settings. Common barriers and challenges are discussed: education and attitudes, compassion fatigue, terminology, paucity of research, aggressive cancer care, and organization and operational considerations. As a result, eight made-in-Canada innovations emerged and are described. Lessons learned and recommendations describe a plan for action.

The US Public Health Service "treating tobacco use and dependence clinical practice guidelines" as a legal standard of care.

The important factors in evaluating the role of clinical practice guidelines (CPGs) in medical malpractice litigation have been discussed for several years, but have focused on broad policy implications rather than on a concrete example of how an actual guideline might be evaluated. There are four items that need to be considered in negligence torts: legal duty, a breach of that duty, causal relationship between breach and injury, and damages. To identify the arguments related to legal duty. The Treating Tobacco Use and Dependence (revised 2000) CPG, sponsored by the US Public Health Service, recommends effective and inexpensive treatments for nicotine addiction, the largest preventable cause of death in the US, and can be used as an example to focus on important considerations about the appropriateness of CPGs in the judicial system. Furthermore, the failure of many doctors and hospitals to deal with tobacco use and dependence raises the question of whether this failure could be considered malpractice, given the Public Health Service guideline's straightforward recommendations, their efficacy in preventing serious disease and cost-effectiveness. Although each case of medical malpractice depends on a multitude of factors unique to individual cases, a court could have sufficient basis to find that the failure to adequately treat the main cause of preventable disease and death in the US qualifies as a violation of the legal duty that doctors and hospitals owe to patients habituated to tobacco use and dependence.

Clinical practice guidelines are structured recommendations that help physicians and patients to make proper decisions when dealing with a specific clinical condition. Because blunt abdominal trauma causes a various range of mild, single-system, and multisystem injuries, early detection will help to reduce mortality and resulting disability. Emergency treatment should be initiated based on CPGs. This study aimed to determine the variables affecting implementing blunt abdominal trauma CPGs in an Iranian hospital. This study was conducted as a qualitative and phenomenology study in the Family Hospital in Tehran (Iran) in 2015. The research population included eight experts and key people in the area of blunt abdominal trauma clinical practice guidelines. Sampling was based on purposive and nonrandom methods. A semistructured interview was done for the data collection. A framework method was applied for the data analysis by using Atlas.ti software. After framework analyzing and various reviewing and deleting and combining the codes from 251 codes obtained, 15 families and five super families were extracted, including technical knowledge barriers, economical barriers, barriers related to deployment and monitoring, political will barriers, and managing barriers. Structural reform is needed for eliminating the defects available in the healthcare system. As with most of the codes, subconcepts and concepts are classified into the field of human resources; it seems that the education and knowledge will be more important than other resources such as capital and equipment.

Clinical practice guidelines (CPGs) have been developed with the aim of helping health professionals, patients, and caregivers make decisions about their health care, using the best available evidence. In many cases, incorporation of these recommendations into clinical practice also implies a need for changes in routine clinical practice. Using educational games as a strategy for implementing recommendations among health professionals has been demonstrated to be effective in some studies; however, evidence is still scarce. The primary objective of this study is to assess the effectiveness of a teaching strategy for the implementation of CPGs using educational games (e-learning EDUCAGUIA) to improve knowledge and skills related to clinical decision-making by residents in family medicine. The primary objective will be evaluated at 1 and 6 months after the intervention. The secondary objectives are to identify barriers and facilitators for the use of guidelines by residents of family medicine and to describe the educational strategies used by Spanish teaching units of family and community medicine to encourage implementation of CPGs. We propose a multicenter clinical trial with randomized allocation by clusters of family and community medicine teaching units in Spain. The sample size will be 394 residents (197 in each group), with the teaching units as the randomization unit and the residents comprising the analysis unit. For the intervention, both groups will receive an initial 1-h session on clinical practice guideline use and the usual dissemination strategy by e-mail. The intervention group (e-learning EDUCAGUIA) strategy will consist of educational games with hypothetical clinical scenarios in a virtual environment. The primary outcome will be the score obtained by the residents on evaluation questionnaires for each clinical practice guideline. Other included variables will be the sociodemographic and training variables of the residents and the teaching unit characteristics. The statistical analysis will consist of a descriptive analysis of variables and a baseline comparison of both groups. For the primary outcome analysis, an average score comparison of hypothetical scenario questionnaires between the EDUCAGUIA intervention group and the control group will be performed at 1 and 6 months post-intervention, using 95 % confidence intervals. A linear multilevel regression will be used to adjust the model. The identification of effective teaching strategies will facilitate the incorporation of available knowledge into clinical practice that could eventually improve patient outcomes. The inclusion of information technologies as teaching tools permits greater learning autonomy and allows deeper instructor participation in the monitoring and supervision of residents. The long-term impact of this strategy is unknown; however, because it is aimed at professionals undergoing training and it addresses prevalent health problems, a small effect can be of great relevance.

Comparison of clinical practice guideline (CPG) recommendations and reported physician management of gastro-enteritis at Paediatric Research in Emergency Departments International Collaborative (PREDICT) network sites as a baseline for further randomised controlled trials. Two part survey comprising: (i) review of CPGs from PREDICT sites for gastro-enteritis; and (ii) survey of senior emergency department physicians regarding the management of gastro-enteritis. All 11 PREDICT sites participated. Nine CPGs were available with three sites using a common CPG. For moderate dehydration, eight CPGs advocated nasogastric (NG) rehydration in preference to intravenous (IV) rehydration. The IV route was reserved for severe dehydration or failed NG rehydration. In the second component of the survey, 78 of 83 (94%) physicians responded. In moderate dehydration, 82% of respondents used NG rehydration. In severe dehydration, 86% used IV fluids; 12% used NG and 3% an initial IV bolus followed by NG fluid. Serum electrolytes were measured universally with IV fluid use and by 22% using NG rehydration. The IV fluid bolus was with normal saline (86%). Fifty-four per cent used anti-emetics 'rarely' or 'sometimes'. The commonest agents were ondansetron (60%) and metoclopramide (29%). CPG recommendations and physician practice for the management of gastro-enteritis were similar across PREDICT sites with a focus on NG for moderate dehydration and IV for severe dehydration. A variety of fluids and administration rates were used. Anti-emetics were used infrequently. The efficacy and safety of newer anti-emetics should be explored in collaborative studies. Collaborative development of new CPGs should be considered to simplify fluid regimens.

Background Falls in older adults are a major public health concern due to high prevalence, impact on health outcomes and quality of life, and treatment costs. Physical therapists can play a major role in reducing fall risk for older adults; however, existing clinical practice guidelines (CPGs) related to fall prevention and management are not targeted to physical therapists. Objective The purpose of this clinical guidance statement (CGS) is to provide recommendations to physical therapists to help improve outcomes in the identification and management of fall risk in community-dwelling older adults. Design and Methods The Subcommittee on Evidence-Based Documents of the Practice Committee of the Academy of Geriatric Physical Therapy developed this CGS. Existing CPGs were identified by systematic search and critically appraised using the Appraisal of Guidelines, Research, and Evaluation in Europe II (AGREE II) tool.

Falls in older adults are a major public health concern due to high prevalence, impact on health outcomes and quality of life, and treatment costs. Physical therapists can play a major role in reducing fall risk for older adults; however, existing clinical practice guidelines (CPGs) related to fall prevention and management are not targeted to physical therapists. The purpose of this clinical guidance statement (CGS) is to provide recommendations to physical therapists to help improve outcomes in the identification and management of fall risk in community-dwelling older adults. The Subcommittee on Evidence-Based Documents of the Practice Committee of the Academy of Geriatric Physical Therapy developed this CGS. Existing CPGs were identified by systematic search and critically appraised using the Appraisal of Guidelines, Research, and Evaluation in Europe II (AGREE II) tool. Through this process, 3 CPGs were recommended for inclusion in the CGS and were synthesized and summarized. Screening recommendations include asking all older adults in contact with a health care provider whether they have fallen in the previous year or have concerns about balance or walking. Follow-up should include screening for balance and mobility impairments. Older adults who screen positive should have a targeted multifactorial assessment and targeted intervention. The components of this assessment and intervention are reviewed in this CGS, and barriers and issues related to implementation are discussed. A gap analysis supports the need for the development of a physical therapy-specific CPG to provide more precise recommendations for screening and assessment measures, exercise parameters, and delivery models. This CGS provides recommendations to assist physical therapists in the identification and management of fall risk in older community-dwelling adults. © 2015 American Physical Therapy Association.

Leveraging workflow control patterns in the domain of clinical practice guidelines.

Clinical practice guidelines (CPGs) include recommendations describing appropriate care for the management of patients with a specific clinical condition. A number of representation languages have been developed to support executable CPGs, with associated authoring/editing tools. Even with tool assistance, authoring of CPG models is a labor-intensive task. We aim at facilitating the early stages of CPG modeling task. In this context, we propose to support the authoring of CPG models based on a set of suitable procedural patterns described in an implementation-independent notation that can be then semi-automatically transformed into one of the alternative executable CPG languages. We have started with the workflow control patterns which have been identified in the fields of workflow systems and business process management. We have analyzed the suitability of these patterns by means of a qualitative analysis of CPG texts. Following our analysis we have implemented a selection of workflow patterns in the Asbru and PROforma CPG languages. As implementation-independent notation for the description of patterns we have chosen BPMN 2.0. Finally, we have developed XSLT transformations to convert the BPMN 2.0 version of the patterns into the Asbru and PROforma languages. We showed that although a significant number of workflow control patterns are suitable to describe CPG procedural knowledge, not all of them are applicable in the context of CPGs due to their focus on single-patient care. Moreover, CPGs may require additional patterns not included in the set of workflow control patterns. We also showed that nearly all the CPG-suitable patterns can be conveniently implemented in the Asbru and PROforma languages. Finally, we demonstrated that individual patterns can be semi-automatically transformed from a process specification in BPMN 2.0 to executable implementations in these languages. We propose a pattern and transformation-based approach for the development of CPG models. Such an approach can form the basis of a valid framework for the authoring of CPG models. The identification of adequate patterns and the implementation of transformations to convert patterns from a process specification into different executable implementations are the first necessary steps for our approach.

Little is known about the use of sedation drugs for the management of acute agitation in Hong Kong's Accident and Emergency Departments (AEDs) and how it compares with Australasian practice. The aim of this study was to determine drug preferences, clinicians' perceived confidence in management, barriers/gaps in training and perceived usefulness of existing clinical practice guidelines (CPGs) in Hong Kong. A validated questionnaire was used, with case vignettes typical of patients presenting to AEDs with acute agitation. The questionnaire was distributed by hand to all trainees and fellows of the Hong Kong College of Emergency Medicine (HKCEM). Two reminders were sent. Of 483 HKCEM members, 280 (58.0% [95% CI 53.5-62.3]) responded. For monotherapy, 46.8% (95% CI 41.0-52.6) of respondents chose haloperidol to manage the undifferentiated patient, followed by midazolam (33.9%, 95% CI 28.6-39.7) and diazepam (13.9%, 95% CI 10.4-18.5). Most respondents (83.6%, 95% CI 78.8-87.5) would not administer combination therapy. Respondents were confident in managing agitation overall. The lack of local/institutional CPGs (55.7%, 95% CI 49.9-61.4) was perceived as an important barrier. Institutional guidelines were considered the most useful CPGs (66.4%, 95% CI 60.7-71.7). Most respondents (72.9%, 95% CI 67.4-77.7) perceived a HKCEM endorsed CPG would be useful. Haloperidol and benzodiazepines are frequently used as monotherapy for the management of acute agitation in Hong Kong's AEDs. Management in Hong Kong differs from Australasian practice in that combination therapy is less common and clinicians' choice of sedation drugs are less variable overall. Results suggest that future work on CPG development and training regarding the safe use of combination therapy would be well received. © 2015 Australasian College for Emergency Medicine and Australasian Society for Emergency Medicine.

Implementation of interventions concerning prevention and health promotion in health care has faced particular challenges resulting in a low frequency and quality of these services. In November 2011, the Swedish National Board of Health and Welfare released national clinical practice guidelines to counteract patients' unhealthy lifestyle habits. Drawing on the results of a previous study as a point of departure, the aim of this two-year follow up was to assess the progress of work with lifestyle interventions in primary healthcare as well as the uptake and usage of the new guidelines on lifestyle interventions in clinical practice. Longitudinal study among health professionals with survey at baseline and 2 years later. Development over time and differences between professional groups were calculated with Pearson chi-square test. Eighteen percent of the physicians reported to use the clinical practice guidelines, compared to 58% of the nurses. Nurses were also more likely to consider them as a support in their work than physicians did. Over time, health professionals usage of methods to change patients' tobacco habits and hazardous use of alcohol had increased, and the nurses worked to a higher extent than before with all four lifestyles. Knowledge on methods for lifestyle change was generally high; however, there was room for improvement concerning methods on alcohol, unhealthy eating and counselling. Forty-one percent reported to possess thorough knowledge of counselling skills. Even if the uptake and usage of the CPGs on lifestyle interventions so far is low, the participants reported more frequent counselling on patients' lifestyle changes concerning use of tobacco and hazardous use of alcohol. However, these findings should be evaluated acknowledging the possibility of selection bias in favour of health promotion and lifestyle guidance, and the loss of one study site in the follow up. Furthermore, this study indicates important differences in physicians and nurses' attitudes to and use of the guidelines, where the nurses reported working to a higher extent with all four lifestyles compared to the first study. These findings suggest further investigations on the implementation process in clinical practice, and the physicians' uptake and use of the CPGs.

Background The important factors in evaluating the role of clinical practice guidelines (CPGs) in medical malpractice litigation have been discussed for several years, but have focused on broad policy implications rather than on a concrete example of how an actual guideline might be evaluated. There are four items that need to be considered in negligence torts: legal duty, a breach of that duty, causal relationship between breach and injury, and damages. Objective To identify the arguments related to legal duty. Results The Treating Tobacco Use and Dependence (revised 2000) CPG, sponsored by the US Public Health Service, recommends effective and inexpensive treatments for nicotine addiction, the largest preventable cause of death in the US, and can be used as an example to focus on important considerations about the appropriateness of CPGs in the judicial system. Furthermore, the failure of many doctors and hospitals to deal with tobacco use and dependence raises the question of whether this failure could be considered malpractice, given the Public Health Service guideline's straightforward recommendations, their efficacy in preventing serious disease and cost‐effectiveness. Conclusion Although each case of medical malpractice depends on a multitude of factors unique to individual cases, a court could have sufficient basis to find that the failure to adequately treat the main cause of preventable disease and death in the US qualifies as a violation of the legal duty that doctors and hospitals owe to patients habituated to tobacco use and dependence.

Introduction Clinical practice guidelines are structured recommendations that help physicians and patients to make proper decisions when dealing with a specific clinical condition. Because blunt abdominal trauma causes a various range of mild, single-system, and multisystem injuries, early detection will help to reduce mortality and resulting disability. Emergency treatment should be initiated based on CPGs. This study aimed to determine the variables affecting implementing blunt abdominal trauma CPGs in an Iranian hospital. Methods This study was conducted as a qualitative and phenomenology study in the Family Hospital in Tehran (Iran) in 2015. The research population included eight experts and key people in the area of blunt abdominal trauma clinical practice guidelines. Sampling was based on purposive and nonrandom methods. A semistructured interview was done for the data collection. A framework method was applied for the data analysis by using Atlas.ti software. Results After framework analyzing and various reviewing and deleting and combining the codes from 251 codes obtained, 15 families and five super families were extracted, including technical knowledge barriers, economical barriers, barriers related to deployment and monitoring, political will barriers, and managing barriers. Conclusion Structural reform is needed for eliminating the defects available in the healthcare system. As with most of the codes, subconcepts and concepts are classified into the field of human resources; it seems that the education and knowledge will be more important than other resources such as capital and equipment.

Purpose The purpose of this paper is to critically analyze empirical studies related to the implementation strategies for clinical practice guidelines (CPGs) in intensive care units (ICUs). Design/methodology/approach A systematic review with a narrative synthesis adapted from Popay et al.'s method for a narrative synthesis was conducted. A search using CINAHL, Google Scholar, Academic search complete, Cochrane Register for Randomized Controlled Trials, MEDLINE via PUBMED and grey literature was conducted in 2014 and updated in 2016 (August). After reading the abstracts, titles and full-text articles, 11 ( n=11) research studies met the inclusion criteria. Findings After critical appraisal, using the Joanna Briggs Critical Appraisal Tools, eight randomized controlled trials conducted in adult and neonatal ICUs using implementation strategies remained. Popay et al.'s method for narrative synthesis was adapted and used to analyze and synthesize the data and formulate concluding statements. Included studies found that multi-faceted strategies appear to be more effective than single strategies. Strategies mostly used were printed educational materials, information/ sessions, audit, feedback, use of champion leaders, educational outreach visits, and computer or internet usage. Practical training, monitoring visits and grand rounds were less used. Practical implications Findings can be used by clinicians to implement the best combination of multi-faceted implementation strategies in the ICUs in order to enhance the optimal use of CPGs. Originality/value No systematic review was previously done on the implementation strategies that should be used best for optimal CPG implementation in the ICU.

The prevalence of type 2 diabetes (T2D) in Asia is growing at an alarming rate, posing significant clinical and economic risk to health care stakeholders. Commonly, Asian patients with T2D manifest a distinctive combination of characteristics that include earlier disease onset, distinct pathophysiology, syndrome of complications, and shorter life expectancy. Optimizing treatment outcomes for such patients requires a coordinated inclusive care plan and knowledgeable practitioners. Comprehensive management starts with medical nutrition therapy (MNT) in a broader lifestyle modification program. Implementing diabetes-specific MNT in Asia requires high-quality and transparent clinical practice guidelines (CPGs) that are regionally adapted for cultural, ethnic, and socioeconomic factors. Respected CPGs for nutrition and diabetes therapy are available from prestigious medical societies. For cost efficiency and effectiveness, health care authorities can select these CPGs for Asian implementation following abridgement and cultural adaptation that includes: defining nutrition therapy in meaningful ways, selecting lower cutoff values for healthy body mass indices and waist circumferences (WCs), identifying the dietary composition of MNT based on regional availability and preference, and expanding nutrition therapy for concomitant hypertension, dyslipidemia, overweight/obesity, and chronic kidney disease. An international task force of respected health care professionals has contributed to this process. To date, task force members have selected appropriate evidence-based CPGs and simplified them into an algorithm for diabetes-specific nutrition therapy. Following cultural adaptation, Asian and Asian-Indian versions of this algorithmic tool have emerged. The Asian version is presented in this report.

To estimate the adherence to institutional venous thromboprophylaxis clinical practice guidelines (CPGs) in general surgery patients and to assess the effectiveness of a multi-strategy improvement intervention. A prospective before-after study. Two teaching hospitals located in the city of Buenos Aires, Argentina. Prescriptions belonging to patients admitted to the general surgery wards were evaluated. A multi-strategy intervention that included (i) simplification of institutional CPGs for venous thromboprophylaxis using a single drug at a single dose, based on the American College of Chest Physicians recommendations, (ii) distribution of pocket cards with an algorithm for the implementation of new recommendations to both, physicians and nurses, working in the general surgery units, (iii) educational talks, (iv) paper-based reminders and (v) audit and feedback. The adherence of the venous thromboprophylaxis prescription to the institutional recommendations. The prescriptions of 100 admitted patients before and 90 after the intervention were included in the analysis. The initial rate of adherence was 31%. After the intervention this rate rose to 71.1% (P< 0.001). The major improvement observed was the reduction in omitted prophylaxis in patients at risk of venous thromboembolism from 45 to 13.3% (P< 0.001). In the adjusted model, prescribing compliance with CPGs was five times more likely during the second stage than during the first stage (OR = 5.60, 95% CI = 2.92-10.74). Simple and economical interventions such as those described in this study can improve general surgeons compliance with the institutional and international guidelines, thus assuring patient safety and quality of health care.

Traumatic brain injury (TBI) is common and especially with military service. In Iraq and Afghanistan, explosive blast related TBI has become prominent and is mainly from improvised explosive devices (IED). Civilian standard of care clinical practice guidelines (CPG) were appropriate has been applied to the combat setting. When such CPGs do not exist or are not applicable, new practice standards for the military are created, as for TBI. Thus, CPGs for prehospital care of combat TBI CPG [1] and mild TBI/concussion [2] were introduced as was a DoD system-wide clinical care program, the first large scale system wide effort to address all severities of TBI in a comprehensive organized way. As TBI remains incompletely understood, substantial research is underway. For the DoD, leading this effort are The Defense and Veterans Brain Injury Center, National Intrepid Center of Excellence and the Defense Centers of Excellence for Psychological Health and Traumatic Brain Injury. This program is a beginning, a work in progress ready to leverage advances made scientifically and always with the intent of providing the best care to its military beneficiaries.

After seven years the National Disease Management Guidelines Programme (German DM-CPG Programme) that was established under the auspices of the German Medical Association, the National Association of Statutory Health Insurance Physicians and the Association of the Scientific Medical Societies in Germany has been widely accepted by both health care professionals and patients. DM-CPGs are available as tools for knowledge and quality management for widespread chronic diseases showing need for improvement in treatment pathways and coordination between health care providers. The main objective of the German DM-CPG Programme is to establish consensus among the medical professions on evidence-based key recommendations covering all sectors of health care provision and facilitating the coordination of care for the individual patient over time and across interfaces. German DM-CPGs provide a conceptual basis for disease management and integrative care aiming at the implementation of best practice recommendations for prevention, acute care, rehabilitation, chronic care and management aspects for high priority health care topics. Thus, representatives of all disciplines, professions and patients concerned with the topic of an individual German DM-CPG are involved in the development process. The methodology of guideline development is in accordance with international standards. However, the improvement of strategies for effective implementation and continuous update remain challenging. Future work will also focus on content-related aspects such as co-morbidity, gender and migration background. Copyright © 2010. Published by Elsevier GmbH.

ABSTRACTOur primary objective was to understand the barriers and facilitators associated with the implementation of high-quality clinical practice guidelines (CPGs) for depression and anxiety in patients with dementia or Parkinson's disease (PD). We conducted focus groups or interviews with participants experiencing dementia or PD, their caregivers, and physicians in Calgary, Alberta, and applied the theoretical domains framework and behaviour change wheel to guide data collection and perform a framework analysis. Thirty-three physicians and seven PD patients/caregivers participated. We report barriers and facilitators to the implementation of guideline recommendations for diagnosis, management, and the use of the guidelines. An overarching theme was the lack of evidence for depression or anxiety disorders in dementia or PD, which was prominent for anxiety versus depression. Patients noted difficulties with communicating symptoms and accessing services. Although guidelines are available, physicians have difficulty implementing certain recommendations due primarily to a lack of evidence regarding efficacy.

The Canadian critical care nutrition guidelines in 2013: an update on current recommendations and implementation strategies.

Clinical practice guidelines (CPGs) are systematically developed statements to assist practitioners and patient decisions about appropriate healthcare for specific clinical circumstances, and are designed to minimize practice variation, improve costs, and improve clinical outcomes. The Canadian Critical Care Practice Guidelines (CCPGs) were first published in 2003 and most recently updated in 2013. A total of 68 new randomized controlled trials were identified since the last version in 2009, 50 of them published between 2009 and 2013. The remaining articles were trials published before 2009 but were not identified in previous iterations of the CCPGs. For clinical practice guidelines to be useful to practitioners, they need to be up-to-date and be reflective of the current body of evidence. Herein we describe the process by which the CCPGs were updated. This process resulted in 10 new sections or clinical topics. Of the old clinical topics, 3 recommendations were upgraded, 4 were downgraded, and 27 remained the same. To influence decision making at the bedside, these updated guidelines need to be accompanied by active guideline implementation strategies. Optimal implementation strategies should be guided by local contextual factors including barriers and facilitators to best practice recommendations. Moreover, evaluating and monitoring performance, such as participating in the International Nutrition Survey of practice, should be part of any intensive care unit's performance improvement strategy. The active implementation of the updated CCPGs may lead to better nutrition care and improved patient outcomes in the critical care setting.

We evaluated clinical practice guideline (cpg) recommendations from Cancer Care Ontario's Program in Evidence-Based Care (pebc) for molecularly targeted systemic treatments (tts) and subsequent funding decisions from the Ontario Ministry of Health and Long-Term Care. We identified pebc cpgs on tt published before June 1, 2010, and extracted information regarding the key evidence cited in support of cpg recommendations and the effect size associated with each tt. Those variables were compared with mohltc funding decisions as of June 2011. From 23 guidelines related to 17 tts, we identified 43 recommendations, among which 38 (88%) endorsed tt use. Among all the recommendations, 38 (88%) were based on published key evidence, with 82% (31 of 38) being supported by meta-analyses or phase iii trials. For the 38 recommendations endorsing tts, funding was approved in 28 (74%; odds ratio related to cpg recommendation: 29.9; p = 0.003). We were unable to demonstrate that recommendations associated with statistically significant improvements in overall survival [os: 14 of 16 (88%) vs. 8 of 14 (57%); p = 0.10] or disease- (dfs) or progression-free survival [pfs: 16 of 21 (76%) vs. 3 of 5 (60%); p = 0.59] were more likely to be funded than those with no significant difference. Moreover, we did not observe significant associations between funding approvals and absolute improvements of 3 months or more in os [6 of 6 (100%) vs. 3 of 6 (50%), p = 0.18] or pfs [6 of 8 (75%) vs. 10 of 12 (83%), p = 1.00]. For use of tts, most recommendations in pebc cpgs are based on meta-analyses or phase iii data, and funding decisions were strongly associated with those recommendations. Our data suggest a trend toward increased rates of funding for therapies with statistically significant improvements in os.

Tools developed and disseminated by guideline producers to promote the uptake of their guidelines.

The uptake of clinical practice guidelines (CPGs) is inconsistent, despite their potential to improve the quality of health care and patient outcomes. Some guideline producers have addressed this problem by developing tools to encourage faster adoption of new guidelines. This review focuses on the effectiveness of tools developed and disseminated by guideline producers to improve the uptake of their CPGs. To evaluate the effectiveness of implementation tools developed and disseminated by guideline producers, which accompany or follow the publication of a CPG, to promote uptake. A secondary objective is to determine which approaches to guideline implementation are most effective. We searched the Cochrane Effective Practice and Organisation of Care (EPOC) Group Specialised Register, Cochrane Central Register of Controlled Trials (CENTRAL); NHS Economic Evaluation Database, HTA Database; MEDLINE and MEDLINE In-Process and other non-indexed citations; Embase; PsycINFO; CINAHL; Dissertations and Theses, ProQuest; Index to Theses; Science Citation Index Expanded, ISI Web of Knowledge; Conference Proceedings Citation Index - Science, ISI Web of Knowledge; Health Management Information Consortium (HMIC), and NHS Evidence up to February 2016. We also searched trials registers, reference lists of included studies and relevant websites. We included randomised controlled trials (RCTs) and cluster-RCTs, controlled before-and-after studies (CBAs) and interrupted time series (ITS) studies evaluating the effects of guideline implementation tools developed by recognised guideline producers to improve the uptake of their own guidelines. The guideline could target any clinical area. Two review authors independently extracted data and assessed the risk of bias of each included study using the Cochrane 'Risk of bias' criteria. We graded our confidence in the evidence using the approach recommended by the GRADE working group. The clinical conditions targeted and the implementation tools used were too heterogenous to combine data for meta-analysis. We report the median absolute risk difference (ARD) and interquartile range (IQR) for the main outcome of adherence to guidelines. We included four cluster-RCTs that were conducted in the Netherlands, France, the USA and Canada. These studies evaluated the effects of tools developed by national guideline producers to implement their CPGs. The implementation tools evaluated targeted healthcare professionals; none targeted healthcare organisations or patients.One study used two short educational workshops tailored to barriers. In three studies the intervention consisted of the provision of paper-based educational materials, order forms or reminders, or both. The clinical condition, type of healthcare professional, and behaviour targeted by the CPG varied across studies.Two of the four included studies reported data on healthcare professionals' adherence to guidelines. A guideline tool developed by the producers of a guideline probably leads to increased adherence to the guidelines; median ARD (IQR) was 0.135 (0.115 and 0.159 for the two studies respectively) at an average four-week follow-up (moderate certainty evidence), which indicates a median 13.5% greater adherence to guidelines in the intervention group. Providing healthcare professionals with a tool to improve implementation of a guideline may lead to little or no difference in costs to the health service. Implementation tools developed by recognised guideline producers probably lead to improved healthcare professionals' adherence to guidelines in the management of non-specific low back pain and ordering thyroid-function tests. There are limited data on the relative costs of implementing these interventions.There are no studies evaluating the effectiveness of interventions targeting the organisation of care (e.g. benchmarking tools, costing templates, etc.), or for mass media interventions. We could not draw any conclusions about our second objective, the comparative effectiveness of implementation tools, due to the small number of studies, the heterogeneity between interventions, and the clinical conditions that were targeted.

To organize the clinical practice guidelines (CPGs) related to acupuncture included in the National Guideline Clearinghouse (NGC) to systematically summarize the diseases and disorders most commonly treated with acupuncture, the strength of recommendations for acupuncture and the quality of evidence. The NGC database was systematically searched for guidelines that included acupuncture as an intervention. Two independent reviewers studied the summaries and the full texts of the guidelines and included guidelines based on the inclusion and exclusion criteria. Thirty-nine guidelines were collected with 80 recommendations. The Appraisal of Guidelines for Research and Evaluation (AGREE) II instrument was used to assess the quality of these guidelines. Of the 80 recommendations on acupuncture, 49 recommendations were clearly for acupuncture, 25 recommendations were against acupuncture and 6 recommendations did not indicate any clear recommendations, 37 recommendations were for painful diseases/disorders, and 12 recommendations were for non-painful diseases/disorders. Locomotor system disorders were the most common in the painful diseases/disorders category. Out of all the recommendations for acupuncture, most recommendations (87.76%) were weak in strength, and most of the evidence (40.84%) was of low quality. In the National Guideline Clearinghouse, the recommendations for acupuncture focus on painful diseases/disorders. The recommendations in the guidelines are not high in strength, and most of the evidence is moderate or low in quality.

The increasing prevalence of multimorbidity is a challenge for physicians who have to manage a constantly growing number of patients with simultaneous diseases. Adding to this challenge is the need to incorporate patient preferences as key components of the care process, thanks in part to the emergence of personalized and participatory medicine. In our previous work we proposed a framework employing first order logic to represent clinical practice guidelines (CPGs) and to mitigate possible adverse interactions when concurrently applying multiple CPGs to a multimorbid patient. In this paper, we describe extensions to our methodological framework that (1) broaden our definition of revision operators to support required and desired types of revisions defined in secondary knowledge sources, and (2) expand the mitigation algorithm to apply revisions based on their type. We illustrate the capabilities of the expanded framework using a clinical case study of a multimorbid patient with stable cardiac artery disease who suffers a sudden onset of deep vein thrombosis.

To describe the process of collecting and evaluating evidence for treating rheumatoid arthritis (RA) for developing clinical practice guidelines (CPGs) for rheumatologists in Japan. The task force comprised rheumatologists, epidemiologists, health economists, and patients. First, the critical outcomes were determined according to a three-round Delphi method, and eight topics with 88 clinical questions (CQs) were formulated. A systematic review of CQs was conducted using the Cochran Database of Systematic Reviews, MEDLINE, and Japana Centra Revvo Medicina (2003-2012). A questionnaire survey and focus group interview were performed to capture the patients' values and preferences. Data from the National Health Insurance drug price list and product information provided by pharmaceutical companies were collected to evaluate drug cost and safety. The GRADE approach was used to describe the evidence quality and determine the strength of recommendations. Recommendations were developed using a modified Delphi method by a multidisciplinary panel including patients. Eight meetings and frequent e-mail communications were conducted to draft a quality assessment of evidence and recommendations. For 88 CQs, recommendation statements were determined. Using the GRADE approach, new CPGs successfully addressed important clinical issues for treating RA patients. Timely updating of recommendations should be routinely considered.

The literature demonstrates that medical residents and practicing physicians have an attitudinal-behavioral discordance concerning their positive attitudes towards clinical practice guidelines (CPG), and the implementation of these guidelines into clinical practice patterns. A pilot study was performed to determine if change in a previously identified CPG compliance factor (accessibility) would produce a significant increase in family medicine resident knowledge and attitude toward the guidelines. The primary study intervention involved placing a summary of the Sixth Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure (JNC VI) and the National Cholesterol Education Program Expert Panel on Detection, Evaluation, and Treatment of High Blood Cholesterol in Adults (NCEP III) CPGs in all patient (>18 yr.) charts for a period of three months. The JNC VI and NCEP III CPGs were also distributed to each Wayne State family medicine resident, and a copy of each CPG was placed in the preceptor's area of the involved clinics. Identical pre- and post- intervention questionnaires were administered to all residents concerning CPG knowledge and attitude. Post-intervention analysis failed to demonstrate a significant difference in CPG knowledge. A statistically significant post-intervention difference was found in only on attitude question. The barriers to CPG compliance were identified as 1) lack of CPG instruction; 2) lack of critical appraisal ability; 3) insufficient time; 4) lack of CPG accessibility; and 5) lack of faculty modeling. This study demonstrated no significant post intervention changes in CPG knowledge, and only one question that reflected attitude change. Wider resident access to dedicated clinic time, increased faculty modeling, and the implementation of an electronic record/reminder system that uses a team-based approach are compliance factors that should be considered for further investigation. The interpretation of CPG non-compliance will benefit from a causal matrix focused on physician knowledge, attitudes, and behavior. Recent findings in resident knowledge-behavior discordance may direct the future investigation of physician CPG non-compliance away from generalized barrier research, and toward the development of information that maximizes the sense of individual practitioner urgency and certainty.

Strategies to assess the validity of recommendations: a study protocol

PubMed Central

2013-01-01

Background Clinical practice guidelines (CPGs) become quickly outdated and require a periodic reassessment of evidence research to maintain their validity. However, there is little research about this topic. Our project will provide evidence for some of the most pressing questions in this field: 1) what is the average time for recommendations to become out of date?; 2) what is the comparative performance of two restricted search strategies to evaluate the need to update recommendations?; and 3) what is the feasibility of a more regular monitoring and updating strategy compared to usual practice?. In this protocol we will focus on questions one and two. Methods The CPG Development Programme of the Spanish Ministry of Health developed 14 CPGs between 2008 and 2009. We will stratify guidelines by topic and by publication year, and include one CPG by strata. We will develop a strategy to assess the validity of CPG recommendations, which includes a baseline survey of clinical experts, an update of the original exhaustive literature searches, the identification of key references (reference that trigger a potential recommendation update), and the assessment of the potential changes in each recommendation. We will run two alternative search strategies to efficiently identify important new evidence: 1) PLUS search based in McMaster Premium LiteratUre Service (PLUS) database; and 2) a Restrictive Search (ReSe) based on the least number of MeSH terms and free text words needed to locate all the references of each original recommendation. We will perform a survival analysis of recommendations using the Kaplan-Meier method and we will use the log-rank test to analyse differences between survival curves according to the topic, the purpose, the strength of recommendations and the turnover. We will retrieve key references from the exhaustive search and evaluate their presence in the PLUS and ReSe search results. Discussion Our project, using a highly structured and transparent methodology, will provide guidance of when recommendations are likely to be at risk of being out of date. We will also assess two novel restrictive search strategies which could reduce the workload without compromising rigour when CPGs developers check for the need of updating. PMID:23967896

The uptake of Clinical Practice Guideline (CPG) recommendations that improve outcomes in heart failure (HF) remains suboptimal. We will conduct a systematic review to identify implementation strategies that improve physician adherence to class I recommendations, those with clear evidence that benefits outweigh the risks. We will use American, Canadian and European HF guidelines as our reference. We will conduct a literature search in the databases of MEDLINE, EMBASE, HEALTHSTAR, CINAHL, Cochrane Library, Campbell Collaboration, Joanna Briggs Institute Evidence Based Practice, Centre for Reviews and Dissemination and Evidence Based Practice Centres. We will include prospective studies evaluating implementation interventions aimed at improving uptake of class I CPG recommendations in HF. We will extract data in duplicate. We will classify interventions according to their level of application (ie, provider, organisation, systems level) and common underlying characteristics (eg, education, decision-support, financial incentives) using the Cochrane Effective Practice and Organisation of Care Taxonomy. We will assess the impact of the intervention on adherence to the CPGs. Outcomes will include proportion of eligible patients who were: prescribed a CPG-recommended pharmacological treatment; referred for device consideration; provided self-care education at discharge; and provided left ventricular function assessment. We will include clinical outcomes such as hospitalisations, readmissions and mortality, if data is available. We will identify the common elements of successful and failing interventions, and examine the context in which they were applied, using the Process Redesign contextual framework. We will synthesise the results narratively and, if appropriate, will pool results for meta-analysis. In this review, we will assess the impact of implementation strategies and contextual factors on physician adherence to HF CPGs. We will explore why some interventions may succeed in one setting and fail in another. We will disseminate our findings through briefing reports, publications and presentations. CRD42015017155.

Background The GRADE method represents a new approach to grading the quality of evidence and strength of recommendations in the preparation of Clinical Practice Guidelines (CPG). In the context of a pilot study to assess the implementability of the system in Spain, we considered it relevant to gain an insight into the significance of the perceptions and attitudes expressed by the actual experts participating in the system try-out. Methods Qualitative research with an ethnographic approach, through non-participant observation and focus groups within the context of a consensus workshop in which 19 CPG experts participated to evaluate the GRADE proposal using 12 evidence tables taken from hypertension, asthma and arthritis CPGs. The interventions were recorded, under a guarantee of confidentiality. The transcriptions and field notes were analyzed, based on a sociological discourse analysis model, and the provisional findings were re-sent to participants in order to improve their validity. Results 1) Certain problems over procedure and terminology hindered the acceptance of this new method as a common reference system for the preparation of CPGs. 2). A greater closeness to clinical practice was accompanied by concerns over value judgments and subjectivity, with a demand for greater explicitness in the consensus process. 3). The type of "evidence" on which the guidelines are based, how and by whom the evidence is prepared, and what the role of the different actors should be, all constitute unresolved concerns in the CPG preparation and implementation processes. 4). The grading process is not neutral: professional background, prior experience and the degree of leadership all condition the participants' input and interactions. Conclusion The findings obtained allow the quantitative evaluation to be better interpreted and, in turn, go beyond the particularities of the GRADE method. Adaptation to the complexities of clinical practice, the need for carefully designed multi-disciplinary work and the reflexivity present in the CPG preparation process, all represent lines of debate that are necessary to improve the CPG quality in the Spanish health care sector.

The purpose of guidelines in clinical practice is to improve the effectiveness and efficiency of clinical care. It is known that nationally or internationally produced guidelines which, in particular, do not involve medical processes at the time of consultation, do not take local factors into account, and have no consistent implementation strategy, have limited impact in changing either the behaviour of physicians, or patterns of care. The literature provides evidence for the effectiveness of computerization of CPGs for increasing compliance and improving patient outcomes. Probably the most effective concepts are knowledge-based functions for decision support or monitoring that are integrated in clinical information systems. This approach is mostly restricted by the effort required for development and maintenance of the information systems and the limited number of implemented medical rules. Most of the guidelines are text-based, and are primarily published in medical journals and posted on the internet. However, internet-published guidelines have little impact on the behaviour of physicians. It can be difficult and time-consuming to browse the internet to find (a) the correct guidelines to an existing diagnosis and (b) and adequate recommendation for a specific clinical problem. Our objective is to provide a web-based guideline service that takes as input clinical data on a particular patient and returns as output a customizable set of recommendations regarding diagnosis and treatment. Information in healthcare is to a very large extent transmitted and stored as unstructured or slightly structured text such as discharge letters, reports, forms, etc. The same applies for facilities containing medical information resources for clinical purposes and research such as text books, articles, guidelines, etc. Physicians are used to obtaining information from text-based sources. Since most guidelines are text-based, it would be practical to use a document-based solution that preserves the original cohesiveness. The lack of structure limits the automatic identification and extraction of the information contained in these resources. For this reason, we have chosen a document-based approach using eXtensible Markup Language (XML) with its schema definition and related technologies. XML empowers the applications for in-context searching. In addition it allows the same content to be represented in different ways. Our XML reference clinical data model for guidelines has been realized with the XML schema definition. The schema is used for structuring new text-based guidelines and updating existing documents. It is also used to establish search strategies on the document base. We hypothesize that enabling the physicians to query the available CPGs easily, and to get access to selected and specific information at the point of care will foster increased use. Based on current evidence we are confident that it will have substantial impact on the care provided, and will improve health outcomes.

Vital signs are the primary indicator of physiological status and for determining the need for urgent clinical treatment. Yet, if physiological signs of deterioration are missed, misinterpreted or mismanaged, then critical illness, unplanned intensive care admissions, cardiac arrest and death may ensue. Although evidence demonstrates the benefit of early recognition and management of deteriorating patients, failure to escalate care and manage deteriorating patients remains a relatively frequent occurrence in hospitals. A pragmatic cluster-randomised controlled trial design will be used to measure clinical effectiveness and cost of a facilitation intervention to improve nurses' vital sign measurement, interpretation, treatment and escalation of care for patients with abnormal vital signs. A cost consequence analysis will evaluate the intervention cost and effectiveness, and a process evaluation will determine how the implementation of the intervention contributes to outcomes. We will compare clinical outcomes and costs from standard implementation of clinical practice guidelines (CPGs) to facilitated implementation of CPGs. The primary outcome will be adherence to the CPGs by nurses, as measured by escalation of care as per organisational policy. The study will be conducted in four Australian major metropolitan teaching hospitals. In each hospital, eight to ten wards will be randomly allocated to intervention and control groups. Control wards will receive standard implementation of CPGs, while intervention wards will receive standard CPG implementation plus facilitation, using facilitation methods and processes tailored to the ward context. The intervention will be administered to all nursing staff at the ward level for 6 months. At each hospital, two types of facilitators will be provided: a hospital-level facilitator as the lead; and two ward-level facilitators for each ward. This study uses an innovative, networked approach to facilitation to enable uptake of CPGs. Findings will inform the intervention utility and knowledge translation measurement approaches. If successful, the study methodology and intervention has potential for translation to other health care standards. Australian New Zealand Clinical Trials Registry (ANZCTR), ACTRN12616000544471p.

International lessons in new methods for grading and integrating cost effectiveness evidence into clinical practice guidelines.

Economic evidence is influential in health technology assessment world-wide. Clinical Practice Guidelines (CPG) can enable economists to include economic information on health care provision. Application of economic evidence in CPGs, and its integration into clinical practice and national decision making is hampered by objections from professions, paucity of economic evidence or lack of policy commitment. The use of state-of-art economic methodologies will improve this. Economic evidence can be graded by 'checklists' to establish the best evidence for decision making given methodological rigor. New economic evaluation checklists, Multi-Criteria Decision Analyses (MCDA) and other decision criteria enable health economists to impact on decision making world-wide. We analyse the methodologies for integrating economic evidence into CPG agencies globally, including the Agency of Health Research and Quality (AHRQ) in the USA, National Health and Medical Research Council (NHMRC) and Australian political reforms. The Guidelines and Economists Network International (GENI) Board members from Australia, UK, Canada and Denmark presented the findings at the conference of the International Health Economists Association (IHEA) and we report conclusions and developments since. The Consolidated Guidelines for the Reporting of Economic Evaluations (CHEERS) 24 item check list can be used by AHRQ, NHMRC, other CPG and health organisations, in conjunction with the Drummond ten-point check list and a questionnaire that scores that checklist for grading studies, when assessing economic evidence. Cost-effectiveness Analysis (CEA) thresholds, opportunity cost and willingness-to-pay (WTP) are crucial issues for decision rules in CEA generally, including end-of-life therapies. Limitations of inter-rater reliability in checklists can be addressed by including more than one assessor to reach a consensus, especially when impacting on treatment decisions. We identify priority areas to generate economic evidence for CPGs by NHMRC, AHRQ, and other agencies. The evidence may cover demand for care issues such as involved time, logistics, innovation price, price sensitivity, substitutes and complements, WTP, absenteeism and presentism. Supply issues may include economies of scale, efficiency changes, and return on investment. Involved equity and efficiency measures may include cost-of-illness, disease burden, quality-of-life, budget impact, cost-effective ratios, net benefits and disparities in access and outcomes. Priority setting remains essential and trade-off decisions between policy criteria can be based on MCDA, both in evidence based clinical medicine and in health planning.

Bipolar disorder is a chronic and recurrent mood disorder, which may severely impact on the patient's global functioning. It has been estimated that approximately 1.6% of the population is affected. A long delay in diagnosis and an excessive disparity in the treatment of these patients have been detected. Within the Quality Plan of the Spanish National Health System, one of the key strategies is to improve clinical practice through the development and use of clinical practice guidelines (CPGs). In this context, the CPG on bipolar disorder arises from an agreement between the Ministry of Health and the University of Alcalá, involving the Spanish Association of Neuropsychiatry as developer and project manager. Its main objective is to develop recommendations on the diagnostic, therapeutic and rehabilitative care for patients with bipolar disorder, primarily applicable in the public mental health services. In this paper we present the main recommendations on pharmacological and psychosocial interventions in bipolar disorder. Copyright © 2013 Elsevier España, S.L. All rights reserved.

Framework for enhancing clinical practice guidelines through continuous patient engagement.

Patient engagement in clinical practice guideline (CPG) development is recommended by multiple institutions and instruments measuring guideline quality. Approaches to engaging patients, however, vary between oversight organizations, quality tools and guideline developers. We propose a ten-step framework outlining steps and options for patient engagement in guideline development with the goal of highlighting steps for patient engagement and methods by which this can be achieved. This framework provides a model for continuous patient engagement in CPGs by outlining ten steps of guideline development occurring at the levels of the developer/committee and the individual guideline project. At the developer level, patients can assist in topic nomination (step 1), topic prioritization (step 2) and guideline development group selection (step 3). Within specific guideline projects, patients' opinions may be incorporated when framing the question (step 4), creating an analytic framework and research plan (step 5), conducting the systematic review and conclusion formation (step 6), development of recommendations (step 7) and dissemination and implementation (step 8). At the end of process, patients can again be engaged at the developer level by helping determine when guidelines need updating (step 9) and evaluating the developer's approach to patient engagement (step 10). Patient engagement at each CPG development step has different purposes, mechanisms, advantages and disadvantages, and implications for resource utilization. This framework can serve as a resource for guideline developers desiring to increase patient engagement and reference for researchers investigating engagement methodology at different steps of the CPG lifecycle. © 2016 The Authors.

The high prevalence of COPD together with its high level of misdiagnosis and late diagnosis dictate the necessity for the development and implementation of clinical practice guidelines (CPGs) in order to improve the management of this disease. High-quality, evidence-based international CPGs need to be adapted to the particular situation of each country or region. A new version of the Russian Respiratory Society guidelines released at the end of 2016 was based on the proposal by Global Initiative for Obstructive Lung Disease but adapted to the characteristics of the Russian health system and included an algorithm of pharmacologic treatment of COPD. The proposed algorithm had to comply with the requirements of the Russian Ministry of Health to be included into the unified electronic rubricator, which required a balance between the level of information and the simplicity of the graphic design. This was achieved by: exclusion of the initial diagnostic process, grouping together the common pharmacologic and nonpharmacologic measures for all patients, and the decision not to use the letters A–D for simplicity and clarity. At all stages of the treatment algorithm, efficacy and safety have to be carefully assessed. Escalation and de-escalation is possible in the case of lack of or insufficient efficacy or safety issues. Bronchodilators should not be discontinued except in the case of significant side effects. At the same time, inhaled corticosteroid (ICS) withdrawal is not represented in the algorithm, because it was agreed that there is insufficient evidence to establish clear criteria for ICSs discontinuation. Finally, based on the Global Initiative for Obstructive Lung Disease statement, the proposed algorithm reflects and summarizes different approaches to the pharmacological treatment of COPD taking into account the reality of health care in the Russian Federation.

Transparency ethics in practice: Revisiting financial conflicts of interest disclosure forms in clinical practice guidelines

2017-01-01

Background Authors of clinical practice guidelines (CPGs) disclose financial conflicts of interest (FCOIs) to promote transparency ethics. Typically, they do so on standard declaration forms containing generic open-ended questions on FCOIs. Yet, the literature is scant on the format and effect of alternative disclosure forms. Does supplementing a standard form with subsequent detailed disclosure forms tailored to the context of the CPG improve the yield or accuracy of FCOIs declarations? Methods For an international CPG in gastroenterology on the endoscopic surveillance for colorectal neoplasia in inflammatory bowel disease, we compared the use of a standard FCOIs disclosure form with a contextual FCOIs disclosure form that detailed commercial relations related to the CPG topic. This included manufacturers of endoscopes, endoscopy equipment and accessories. Participants completed the generic form early, and the supplementary contextual form six months later. We then compared the FCOI disclosures obtained. Findings 26 participants provided FCOIs disclosures using both disclosure forms. We found discrepancies regarding (1) the disclosure of FCOIs (presence/absence), and (2) the listing of financial entities. While the number of participants who disclosed a FCOI remained the same (30.8%) using the two forms, disclosures were not from the same individuals: two additional participants disclosed a FCOI, whereas two participants withdrew previous disclosures. Among those who reported a FCOI in either form, we noted inconsistencies in disclosures for 70% of the participants. This included changes in FCOIs disclosure status or modifications of "their commercial relations". Discussion Accurate reporting of FCOIs advances the transparency and ethical integrity of CPGs. Our experience suggests that a contextual FCOIs disclosure form tailored to content of the CPG with narrow, detailed questions provides supplementary, more complete FCOIs declarations than generic forms alone. The finding raises challenges on how forms are best written and formatted, optimally timed, and more effectively processed with sensitivity to professional behaviour, so as to heighten transparency.

The European Federation of Laboratory Medicine (EFLM) and the Union of European Medical Specialists (UEMS) joint Working Group on guidelines recently proposed a checklist to help standardize the description of laboratory investigations in clinical practice guidelines (CPG). Nine CPGs or consensus documents published from 2011 to 2013 describing the investigation of chest pain, diagnosis of acute coronary syndrome, or myocardial infarction were evaluated against the published checklist. Clinical use of troponin analysis are commonly dealt with but the publications present variable, vague and sometimes conflicting information regarding this laboratory test being very much relied on upon making a diagnosis of acute coronary syndrome. Most of the laboratory related checklist items are not considered or need to be updated e.g. suggested analytical quality goals are not applicable for the high sensitive assays and important interferences that may lead to false positive or negative diagnoses are commonly not mentioned. The current paper sums up important analytical and biological issues related to troponin assays and gives suggestions for analytical quality goals that could be included in CPG's.

This article presents the results of a project conducted by the Institut national d'excellence en santé et en services sociaux of Québec to develop quality of care indicators for the management of six chronic illnesses. Indicators were identified through literature searches and analysis of clinical practice guidelines (CPGs). Interdisciplinary expert panels assessed their validity and the strength of the evidence on which they were based. Representatives of patients (N = 19) and professionals (N = 29) were consulted on their relevance and acceptability. Indicators were categorized according to the Chronic Care Model (CCM). A total of 164 indicators were developed, 126 specific to the illnesses under study and 38 on processes and outcomes generic to the CCM. There was convergence between patients and professionals on the relevance of a majority of indicators. Professionals expressed concerns on the indicators measured by means of patient surveys that they considered to be too subjective. The importance given to CPGs as the main source of indicators resulted in a great number of indicators of the technical quality ofcare. Using the CCM contributed to a broader perspective of quality. The consultation process identified some of the concerns of professionals about indicator measurement, thusguidingfuture implementation initiatives.

Determine the acceptability, perceived usefulness, and adoption of implementation tools and technical assistance provided by the Health Technology Assessment Institute (IETS) in hospitals in two regions of Colombia. Assistance was provided for implementation of clinical practice guidelines (CPGs) in 24 hospitals (17 in Antioquia and seven in Cundinamarca) in areas with high prevalence of sexually transmitted infections, and for use of the implementation tools. Health professionals were given surveys and medical specialists were interviewed. Overall, 86% of respondents are familiar with the GPGs, 86% with the tracer recommendations, 79% with the interactive flow charts, and 82% with the evidence sheets, while 41% never used the implementation tools. Of the respondents who used the tools, 55% did so on their work computer, while 24% used their personal telephone. The most useful tools were the evidence sheets and flow charts (98%) and the tracer recommendations (92%). The least useful were the budgetary impact tools (81%). The implementation tools and technical assistance provided in hospitals in two regions of Colombia are perceived as useful and acceptable, although the degree of implementation is low. The findings of this research will help the different actors, such as the Ministry of Health and Social Protection, the IETS, and the Administrative Department of Science, Technology and Innovation (Colciencias), among others, improve their programs for the implementation of clinical practice guidelines.

Clinical practice guidelines within the Southern African development community: a descriptive study of the quality of guideline development and concordance with best evidence for five priority diseases

PubMed Central

2012-01-01

Background Reducing the burden of disease relies on availability of evidence-based clinical practice guidelines (CPGs). There is limited data on availability, quality and content of guidelines within the Southern African Development Community (SADC). This evaluation aims to address this gap in knowledge and provide recommendations for regional guideline development. Methods We prioritised five diseases: HIV in adults, malaria in children and adults, pre-eclampsia, diarrhoea in children and hypertension in primary care. A comprehensive electronic search to locate guidelines was conducted between June and October 2010 and augmented with email contact with SADC Ministries of Health. Independent reviewers used the AGREE II tool to score six quality domains reporting the guideline development process. Alignment of the evidence-base of the guidelines was evaluated by comparing their content with key recommendations from accepted reference guidelines, identified with a content expert, and percentage scores were calculated. Findings We identified 30 guidelines from 13 countries, publication dates ranging from 2003-2010. Overall the 'scope and purpose' and 'clarity and presentation' domains of the AGREE II instrument scored highest, median 58%(range 19-92) and 83%(range 17-100) respectively. 'Stakeholder involvement' followed with median 39%(range 6-75). 'Applicability', 'rigour of development' and 'editorial independence' scored poorly, all below 25%. Alignment with evidence was variable across member states, the lowest scores occurring in older guidelines or where the guideline being evaluated was part of broader primary healthcare CPG rather than a disease-specific guideline. Conclusion This review identified quality gaps and variable alignment with best evidence in available guidelines within SADC for five priority diseases. Future guideline development processes within SADC should better adhere to global reporting norms requiring broader consultation of stakeholders and transparency of process. A regional guideline support committee could harness local capacity to support context appropriate guideline development. PMID:22221856

Analysis of a private insurer's administrative data set revealed significant variation in the length of hospital stay following hernia surgery. This review examined factors influencing the performance of day surgery for inguinal, femoral and umbilical hernia repair in adults. A systematic literature search was conducted in the PubMed, Embase and Cochrane Library databases to identify studies and clinical practice guidelines (CPGs) comparing same day hernia surgery to surgery followed by an overnight stay. Screening of studies by abstract and full text was completed by a single researcher and checked by a second. Studies were selected for inclusion based on a step-wise approach across three phases. Limited evidence from one systematic review, and three case series studies including 3213 patients found that same day hernia surgery was as safe and effective as an overnight stay. All identified CPGs recommended a same day procedure for most patients. Two case series studies reported that 3-8% of patients were ineligible for day procedures due to medical reasons; however, the characteristics of patients, in general, which are not suitable, have not been adequately investigated. Day surgery for groin hernia repair is safe and effective for most patients. However, evidence-based support is only one of many factors that may contribute to the uptake of day surgery in Australia. There is an opportunity for key stakeholders across the private healthcare system to deliver an equally effective but more sustainable and affordable hernia care by increasing the day surgery rates. © 2018 Royal Australasian College of Surgeons.

The American Pediatric Surgical Association Trauma Committee proposed the use of a clinical practice guideline (CPG) for the non-operative management of isolated splenic injuries in 1998. An analysis was conducted to determine the financial impact of CPGs on the management of these injuries. The Pediatric Health Information System database, which contains data from 44 children's hospitals, was used to identify children who sustained a graded isolated splenic injury between June 2005 and June 2010. Demographics, length of stay (LOS), readmission rates, and laboratory, imaging, procedural, and total cost data were determined for all hospitals verified as a pediatric trauma center by the American College of Surgeons and/or designated by their local authority. Comparisons were made between facilities self-identifying as having a splenic injury management CPG and those without a CPG. Children (1,154) with isolated splenic injuries (grades 1-4) were cared for in 26 pediatric trauma centers: 20 with a CPG and 6 without (non-CPG). Median costs were significantly lower at CPG than non-CPG centers for imaging (US $163 vs. US $641, P < .001), laboratory (US $629 vs. US $1,044, P < .001), and total hospital stay (US $9,868 vs. US $10,830, P < .001). The median LOS for CPG and non-CPG centers were similar (3 vs. 2 days, P = .38), as were readmission rates within 90 days (3.1 vs. 5.1 %, P = .21). Multiple linear regression indicated that LOS (P < .001) and utilization of a CPG (P = .007) are significant independent predictors of total cost. Utilization of a CPG to manage children with isolated splenic injuries at a pediatric trauma center results in significantly reduced imaging, laboratory, and total hospital costs independent of patient age, gender, grade, and LOS.

The main objective of this study is to determine the current use of lung cancer diagnostic procedures in two large hospitals in the Netherlands, to explore deviations in guideline adherence between the hospitals, and to estimate the budget impact of the diagnostic work-up as well as the over- and underutilization. A state transition model for the diagnostic pathway for lung cancer patients was developed using existing clinical practice guidelines (CPG) combined with a systematic literature. In addition to the CPGs depicting current practice, diagnostic utilization was gathered in two large hospitals representing an academic tertiary care hospital and a large regional teaching hospital for patients, who were selected from the Netherlands cancer registry. The total population consisted of 376 patients with lung cancer. Not in all cases the guideline was followed, for instance in the usage of MR brain with stage III lung cancer patients (n = 70). The state-transition model predicts an average budget impact for the diagnostic pathway per patient estimated of € 2496 in the academic tertiary care hospital and € 2191 in the large regional teaching hospital. The adherence to the CPG's differed between hospitals, which questions the adherence to CPG's in general. Adherence to CPG's could lead to less costs in the diagnostic pathway for lung cancer patients.

Previous surveys of organizations that support the development of evidence-informed health policies have focused on organizations that produce clinical practice guidelines (CPGs) or undertake health technology assessments (HTAs). Only rarely have surveys focused at least in part on units that directly support the use of research evidence in developing health policy on an international, national, and state or provincial level (i.e., government support units, or GSUs) that are in some way successful or innovative or that support the use of research evidence in low- and middle-income countries (LMICs). We drew on many people and organizations around the world, including our project reference group, to generate a list of organizations to survey. We modified a questionnaire that had been developed originally by the Appraisal of Guidelines, Research and Evaluation in Europe (AGREE) collaboration and adapted one version of the questionnaire for organizations producing CPGs and HTAs, and another for GSUs. We sent the questionnaire by email to 176 organizations and followed up periodically with non-responders by email and telephone. We received completed questionnaires from 152 (86%) organizations. More than one-half of the organizations (and particularly HTA agencies) reported that examples from other countries were helpful in establishing their organization. A higher proportion of GSUs than CPG- or HTA-producing organizations involved target users in the selection of topics or the services undertaken. Most organizations have few (five or fewer) full-time equivalent (FTE) staff. More than four-fifths of organizations reported providing panels with or using systematic reviews. GSUs tended to use a wide variety of explicit valuation processes for the research evidence, but none with the frequency that organizations producing CPGs, HTAs, or both prioritized evidence by its quality. Between one-half and two-thirds of organizations do not collect data systematically about uptake, and roughly the same proportions do not systematically evaluate their usefulness or impact in other ways. The findings from our survey, the most broadly based of its kind, both extend or clarify the applicability of the messages arising from previous surveys and related documentary analyses, such as how the 'principles of evidence-based medicine dominate current guideline programs' and the importance of collaborating with other organizations. The survey also provides a description of the history, structure, processes, outputs, and perceived strengths and weaknesses of existing organizations from which those establishing or leading similar organizations can draw.

A collaborative, multidisciplinary guideline adaptation process was developed to construct a single overarching, evidence-based clinical practice guideline (CPG) for all primary care practitioners responsible for the management of low back pain (LBP) to curb the use of ineffective treatments and improve patient outcomes. The adaptation strategy, which involved multiple committees and partnerships, leveraged existing knowledge transfer connections to recruit guideline development group (GDG) members and ensure that all stakeholders had a voice in the guideline development process. Videoconferencing was used to coordinate the large, geographically dispersed GDG. Information services and health technology assessment experts were used throughout the process to lighten the GDG's workload. The GDG reviewed seven seed guidelines and drafted an Alberta-specific guideline during 10 half-day meetings over a 12-month period. The use of ad hoc subcommittees to resolve uncertainties or disagreements regarding evidence interpretation expedited the process. Challenges were encountered in dealing with subjectivity, guideline appraisal tools, evidence source limitations and inconsistencies, and the lack of sophisticated evidence analysis inherent in guideline adaptation. Strategies for overcoming these difficulties are discussed. Guideline adaptation is useful when resources are limited and good-quality seed CPGs exist. The Ambassador Program successfully utilized existing stakeholder interest to create an overarching guideline that aligned guidance for LBP management across multiple primary care disciplines. Unforeseen challenges in guideline adaptation can be overcome with credible seed guidelines, a consistently applied and transparent methodology, and clear documentation of the subjective contextualization process. Multidisciplinary stakeholder input and an open, trusting relationship among all contributors will ensure that the end product is clinically meaningful. © 2010 Blackwell Publishing Ltd.

Evaluation and management of combat-related spinal injuries: a review based on recent experiences.

2012-09-01

The current approach to the evaluation and treatment of military casualties in the Global War on Terror is informed by medical experience from prior conflicts and combat encounters from the last 10 years. In an effort to standardize the care provided to military casualties in the ongoing conflicts, the Department of Defense (DoD) has published Clinical Practice Guidelines (CPGs) that deal specifically with the combat casualty sustaining a spinal injury. However, the combat experience with spine injuries in the present conflicts remains incompletely described. To describe the CPGs for the care of the combat casualty with suspected spine injuries and discuss them in light of the published military experience with combat-related spinal trauma. Literature review. A literature review was conducted regarding published works that discussed the incidence, epidemiology, and management of combat-related spinal trauma. The CPGs, established by the DoD, are discussed in light of actual military experiences with spine trauma, the present situation in the forward surgical teams and combat support hospitals treating casualties in theater, and recent publications in the field of spine surgery. In the conventional wars fought by the United States between 1950 and 1991 (Korea, Vietnam, Gulf War I), the incidence of spine injuries remained close to 1% of all combat casualties. However, in the Global War on Terror, the enemy has relied on implements of asymmetric warfare, including sniper attacks, ambush, roadside bombs, and improvised explosive devices. The increase in explosive mechanisms of injury has elevated the number of soldiers exposed to blunt force trauma and, consequently, recent publications reported the highest incidence of combat-related spinal injuries in American military history. Wounded soldiers are expeditiously evacuated through the echelons of care but typically do not receive surgical management in theater. The current CPGs for the care of soldiers with combat-related spinal injuries should be re-examined in light of data regarding the increasing number of spine injuries, new injury patterns, such as lumbosacral dissociation and low lumbar burst fractures, and recent reports within the field of spine surgery as a whole. American and coalition forces are sustaining the highest spine combat casualty rates in recorded history and previously unseen injuries are being encountered with increased frequency. While the CPGs provide useful direction in terms of the evaluation and management of combat casualties with spine injuries, such recommendations may warrant periodic re-evaluation in light of recent combat experiences and evolving scientific evidence within the spine literature.

To report the current quality measures that are applicable to orthopaedic sports medicine physicians. Six databases were searched with a customized search term to identify quality measures relevant to orthopaedic sports medicine surgeons: MEDLINE/PubMed, EMBASE, the National Quality Forum (NQF) Quality Positioning System (QPS), the Agency for Healthcare Research and Quality (AHRQ) National Quality Measures Clearinghouse (NQMC), the Physician Quality Reporting System (PQRS) database, and the American Academy of Orthopaedic Surgeons (AAOS) website. Results were screened by 2 Board-certified orthopaedic surgeons with fellowship training in sports medicine and dichotomized based on sports medicine-specific or general orthopaedic (nonarthroplasty) categories. Hip and knee arthroplasty measures were excluded. Included quality measures were further categorized based on Donabedian's domains and the Center for Medicare and Medicaid (CMS) National Quality Strategy priorities. A total of 1,292 quality measures were screened and 66 unique quality measures were included. A total of 47 were sports medicine-specific and 19 related to the general practice of orthopaedics for a fellowship-trained sports medicine specialist. Nineteen (29%) quality measures were collected within PQRS, with 5 of them relating to sports medicine and 14 relating to general orthopaedics. AAOS Clinical Practice Guidelines (CPGs) comprised 40 (60%) of the included measures and were all within sports medicine. Five (8%) additional measures were collected within AHRQ and 2 (3%) within NQF. Most quality measures consist of process rather than outcome or structural measures. No measures addressing concussions were identified. There are many existing quality measures relating to the practice of orthopaedic sports medicine. Most quality measures are process measures described within PQRS or AAOS CPGs. Knowledge of quality measures are important as they may be used to improve care, are increasingly being used to determine physician reimbursement, and can inform future quality measure development efforts.

2012-04-01

India and other countries in Asia are experiencing rapidly escalating epidemics of type 2 diabetes (T2D) and cardiovascular disease. The dramatic rise in the prevalence of these illnesses has been attributed to rapid changes in demographic, socioeconomic, and nutritional factors. The rapid transition in dietary patterns in India-coupled with a sedentary lifestyle and specific socioeconomic pressures-has led to an increase in obesity and other diet-related noncommunicable diseases. Studies have shown that nutritional interventions significantly enhance metabolic control and weight loss. Current clinical practice guidelines (CPGs) are not portable to diverse cultures, constraining the applicability of this type of practical educational instrument. Therefore, a transcultural Diabetes Nutrition Algorithm (tDNA) was developed and then customized per regional variations in India. The resultant India-specific tDNA reflects differences in epidemiologic, physiologic, and nutritional aspects of disease, anthropometric cutoff points, and lifestyle interventions unique to this region of the world. Specific features of this transculturalization process for India include characteristics of a transitional economy with a persistently high poverty rate in a majority of people; higher percentage of body fat and lower muscle mass for a given body mass index; higher rate of sedentary lifestyle; elements of the thrifty phenotype; impact of festivals and holidays on adherence with clinic appointments; and the role of a systems or holistic approach to the problem that must involve politics, policy, and government. This Asian Indian tDNA promises to help guide physicians in the management of prediabetes and T2D in India in a more structured, systematic, and effective way compared with previous methods and currently available CPGs.

We aimed to report a large series of idiopathic granulomatous lobular mastitis (IGLM) from Iran and sketch preliminary clinical practice guidelines (CPG) for approaching an inflammatory breast mass. In a retrospective records review, 43 consecutive IGLM cases were studied. Data on baseline, clinical, imaging, and pathologic characteristics were collected. The mean age of the women was 33.5 years. All but 1 were married and had given birth. 16% had a cancer-like presentation. Inflammatory signs, architectural distortion, and a nodular pattern were the most common findings clinically, mammographically and ultrasonographically, respectively. 29.5% of the pathological reports indicated necrosis which was more common in younger subjects (p = 0.016); microabscesses were associated with a shorter lactation course (p = 0.006). Corticosteroids had been used as the initial treatment modality in 51%, immunosuppressive agents had not been administered, and a 16% relapse rate was recorded. We recognized the need for a multidisciplinary approach covering radiology, oncology, and surgery to best handle diagnostic and therapeutic issues and manage relevant infections as well as the major differential diagnosis, i.e. malignancy. We hypothesized that a shorter lactation period may cause more milk stasis and extravasation and be contributory to IGLM. CPGs are needed to incorporate the needed multidisciplinary approach and to standardize IGLM care. We present one such guideline.

Evaluation of feasibility and effectiveness of Surviving Sepsis Campaign (SSC) Guidelines implementation at a Pediatric Intensive Care Unit (PICU) in Saudi Arabia to reduce severe sepsis associated mortality. Retrospective data analysis for a prospective quality improvement (QI) initiative. PICU at King Saud University Medical City, Saudi Arabia. Children ≤14 years of age admitted to the PICU from July 2010 to March 2011 with suspected or proven sepsis. Comparisons were made to a previously admitted group of patients with sepsis from October 2009 to June 2010. Adaptation and implementation of the Surviving Sepsis Campaign-Clinical Practice Guidelines (SSC-CPGs) through AGREE instrument and ADAPTE process. We reported pre- and post-implementation outcome of interest for this QI initiative, annual sepsis-related mortality rate. Furthermore, we reported follow-up of annual mortality rate until December 2016. Sixty-five patients was included in the study (42 in post-guidelines implementation group and 23 in pre-guidelines implementation group). Mortality was insignificantly lower in the post-implementation group (26.2% vs. 47.8%; P = 0.079). However, when adjusted for severity, identified by number of failing organs in the multivariate regression analysis, the mortality difference was favorable for the post-implementation group (P = 0.006). The lower sepsis-related mortality rate was also sustained, with an average mortality rate of 15.11% for the subsequent years (2012-16). Adaptation and implementation of SSC Guidelines in our setting support its feasibility and potential benefits. However, a larger study is recommended to explore detailed compliance rates.

To determine the impact of implementing clinical practice guidelines (CPGs) in the treatment of community-acquired pneumonia (CAP) in the emergency department (ED) by analyzing case management decisions (admission or discharge, appropriateness and timeliness of antibiotic therapy, complementary tests) and the consequent results (clinical stabilization time, length of hospital stay, re-admission to ED and mortality). A prospective, observational, descriptive, comparative study carried out from 1st January 2008 to 1st August 2009 in two phases: before and after the implementation of the "Management of CAP in ED" SEMES-SEPAR (Spanish Society of Emergency Medicine - Spanish Society of Pneumology and Thoracic Surgery) clinical practice guidelines from 2008. Two hundred adult patients treated in the ED with a diagnosis of CAP were included in the study, both in the pre-intervention and post-intervention groups. The application of the guidelines increased the administration of early and appropriate antibiotic therapy (P<.001) and shortened both the total antibiotic therapy (P<.001) and the intravenous antibiotic therapy (P=.042) times. Time to clinical stabilization (P=.027), length of hospital stay (1.14 days, P=.01), intra-hospital mortality (P=.004) and total 30-day mortality (P=.044) were all reduced. Assessment with the Pneumonia Severity Index (PSI) and biomarkers aided in appropriate decision-making concerning admission/discharge (P<.001). The implementation of the SEMES-SEPAR 2008 guidelines, along with the use of PSI and biomarkers, significantly improved the entire treatment process of CAP. This benefitted both patients and the system by reducing mortality and improving the results of other patient management factors. Copyright © 2012 SEPAR. Published by Elsevier España, S.L.

To develop and evaluate Diabetes Web-Centric Information and Support Environment (D-WISE) that offers 1) a computerized decision-support system to assist physicians to A) use the Canadian Diabetes Association clinical practice guidelines (CDA CPGs) to recommend evidence-informed interventions; B) offer a computerized readiness assessment strategy to help physicians administer behaviour-change strategies to help patients adhere to disease self-management programs; and 2) a patient-specific diabetes self-management application, accessible through smart mobile devices, that offers behaviour-change interventions to engage patients in self-management. The above-mentioned objectives were pursued through a knowledge management approach that involved 1) Translation of paper-based CDA CPGs and behaviour-change models as computerized decision-support tools that will assist physicians to offer evidence-informed and personalized diabetes management and behaviour-change strategies; 2) Engagement of patients in their diabetes care by generating a diabetes self-management program that takes into account their preferences, challenges and needs; 3) Empowering patients to self-manage their condition by providing them with personalized educational and motivational messages through a mobile self-management application. The theoretical foundation of our research is grounded in behaviour-change models and healthcare knowledge management. We used 1) knowledge modelling to computerize the paper-based CDA CPGs and behaviour-change models, in particular, the behaviour-change strategy elements of A) readiness-to-change assessments; B) motivation-enhancement interventions categorized along the lines of patients' being ready, ambivalent or not ready; and C) self-efficacy enhancement. The CDA CPGs and the behaviour-change models are modelled and computerized in terms of A) a diabetes management ontology that serves as the knowledge resource for all the services offered by D-WISE; B) decision support services that use logic-based reasoning algorithms to utilize the knowledge encoded within the diabetes management ontology to assist physicians by recommending patient-specific diabetes-management interventions and behaviour-change strategies; C) a mobile diabetes self-management application to engage and educate diabetes patients to self-manage their condition in a home-based setting while working in concert with their family physicians. We have been successful in creating and conducting a usability assessment of the physician decision support tool. These results will be published once the patient self- management application has been evaluated. D-WISE will be evaluated through pilot studies measuring 1) the usability of the e-Health interventions; and 2) the impact of the interventions on patients' behaviour changes and diabetes control.

[Central Pattern Generators: Mechanisms of the Activity and Their Role in the Control of "Automatic" Movements].

PubMed

Arshavsky, I; Deliagina, T G; Orlovsky, G N

2015-01-01

Central pattern generators (CPGs) are a set of interconnected neurons capable of generating a basic pattern of motor output underlying "automatic" movements (breathing, locomotion, chewing, swallowing, and so on) in the absence of afferent signals from the executive motor apparatus. They can be divided into the constitutive CPGs active throughout the entire lifetime (respiratory CPGs) and conditional CPGs controlling episodic movements (locomotion, chewing, swallowing, and others). Since a motor output of CPGs is determined by their internal organization, the activities of the conditional CPGs are initiated by simple commands coming from higher centers. We describe the structural and functional organization of the locomotor CPGs in the marine mollusk Clione limacina, lamprey, frog embryo, and laboratory mammals (cat, mouse, and rat), CPGs controlling the respiratory and swallowing movements in mammals, and CPGs controlling discharges of the electric organ in the gymnotiform fish. It is shown that in all these cases, the generation of rhythmic motor output is based both on the endogenous (pacemaker) activity of specific groups of interneurons and on interneural interactions. These two interrelated mechanisms complement each other, ensuring the high reliability of CPG functionality. We discuss how the experience obtained in studying CPGs can be used to understand mechanisms of more complex functions of the brain, including its cognitive functions.

The current CPG in epilepsy is based on the scientific method, which extracts recommendations from published scientific evidence. A reduction in the variability in clinical practice through standardization of medical practice has become its main function. This CPG is focused on comprehensive care for individuals affected by epilepsy as a primary and predominant symptom, regardless of the age of onset and medical policy. 1. Creation of GE-SEN neurologists working group, in collaboration with Neuropediatricians, Neurophysiologists and Neuroradiologists. 2. Identification of clinical areas to be covered: diagnosis, prognosis and treatment. 3. Search and selection of the relevant scientific evidence. 4. Formulation of recommendations based on the classification of the available scientific evidence. It contains 161 recommendations of which 57% are consensus between authors and publishers, due to an important lack of awareness in many fields of this pathology. This Epilepsy CPG formulates recommendations based on explicit scientific evidence as a result of a formal and rigorous methodology, according to the current knowledge in the pre-selected areas. This paper includes the CPG chapter dedicated to emergency situations in seizures and epilepsy, which may present as a first seizure, an unfavorable outcome in a patient with known epilepsy, or status epilepticus as the most severe manifestation.

To describe the prescribing practice of emergency medicine clinicians in the management of highly agitated patients and to identify perceived barriers to management and the gaps in training. We undertook an anonymous cross-sectional mail survey of the Australasian College for Emergency Medicine (ACEM) members (fellows and advanced trainees) between June and September 2009. A questionnaire including a case vignette of a hypothetical patient and three clinical scenarios was employed to ascertain prescribing practice and assess perceived barriers to management, confidence and the perceived usefulness of existing and future Clinical Practice Guidelines (CPGs). All 2052 ACEM members were surveyed. However, seven had incorrect postal addresses and could not be reached. Of the remaining 2045, 786/2052 (38.3%, 95% CI 36.2-40.5) responses were received. Of the 786 respondents, 783 were practicing clinicians. If monotherapy was chosen, 622/783 (79.4%, 95% CI 76.4-82.2) of respondents preferred midazolam to manage the common scenario where no history was available, followed by haloperidol 45/783 (5.8%, 95% CI 4.3-7.7) and olanzapine 38/783 (4.9%, 95% CI 3.5-6.7). Most respondents 500/783 (63.9%, 95% CI 60.4-67.2) would also administer another sedative (combination therapy). Important perceived barriers to agitation management included lack of both training (352/783 [45.0%, 95% CI 41.4-48.5]) and a national CPG (313/783 [40.0%, 95% CI 36.5-43.5]). Respondents were generally confident in all aspects of management, although relatively fewer trainees were confident in determining dosing. Institutional CPGs were considered most useful for 415/783 (53.0%, 95% CI 49.4-56.5) respondents. If an ACEM-endorsed CPG were to be developed in the future, 634/783 (81.0%, 95% CI 78.0-83.6) respondents would consider this useful. There is considerable variation in the management of hypothetical cases of acute agitation in Australasian EDs. Benzodiazepines and antipsychotics, either alone or in combination, are commonly used. An ACEM-endorsed, Australasian CPG was perceived as useful. © 2010 The Authors. EMA © 2010 Australasian College for Emergency Medicine and Australasian Society for Emergency Medicine.

Enhanced Recovery After Surgery (ERAS) protocols have been shown to increase recovery, decrease complications, and reduce length of stay. However, they are difficult to implement. To develop and implement an ERAS clinical practice guideline (CPG) at multiple hospitals. A tailored strategy based on the Knowledge-to-action (KTA) cycle was used to develop and implement an ERAS CPG at 15 academic hospitals in Canada. This included an initial audit to identify gaps and interviews to assess barriers and enablers to implementation. Implementation included development of an ERAS guideline by a multidisciplinary group, communities of practice led by multidiscipline champions (surgeons, anesthesiologists, and nurses) both provincially and locally, educational tools, and clinical pathways as well as audit and feedback. The initial audit revealed there was greater than 75% compliance in only 2 of 18 CPG recommendations. Main themes identified by stakeholders were that the CPG must be based on best evidence, there must be increased communication and collaboration among perioperative team members, and patient education is essential. ERAS and Pain Management CPGs were developed by a multidisciplinary team and have been adopted at all hospitals. Preliminary data from more than 1000 patients show that the uptake of recommended interventions varies but despite this, mean length of stay has decreased with low readmission rates and adverse events. On the basis of short-term findings, our results suggest that a tailored implementation strategy based on the KTA cycle can be used to successfully implement an ERAS program at multiple sites.

Extensive cross-talk between signaling pathways is required to integrate the myriad of extracellular signal combinations at the cellular level. Gene duplication events may lead to the emergence of novel functions, leaving groups of similar genes - termed paralogs - in the genome. To distinguish critical paralog groups (CPGs) from other paralogs in human signaling networks, we developed a signaling network-based method using cross-talk annotation and tissue-specific signaling flow analysis. 75 CPGs were found with higher degree, betweenness centrality, closeness, and ‘bowtieness’ when compared to other paralogs or other proteins in the signaling network. CPGs had higher diversity in all these measures, with more varied biological functions and more specific post-transcriptional regulation than non-critical paralog groups (non-CPG). Using TGF-beta, Notch and MAPK pathways as examples, SMAD2/3, NOTCH1/2/3 and MEK3/6-p38 CPGs were found to regulate the signaling flow of their respective pathways. Additionally, CPGs showed a higher mutation rate in both inherited diseases and cancer, and were enriched in drug targets. In conclusion, the results revealed two distinct types of paralog groups in the signaling network: CPGs and non-CPGs. Thus highlighting the importance of CPGs as compared to non-CPGs in drug discovery and disease pathogenesis. PMID:27922122

Today medicine is facing a "knowledge crisis" in that explosively expanding medical knowledge encounters limited abilities to disseminate new practices [1]. Clinical practice guidelines (CPGs) are intended to promote high standards of care in specific areas of medicine by summarizing best clinical practice based on careful reviews of current research. However, doctors are often short of time to study these documents and check their updates, have little motivation for strict adherence to them. A systematic review of 11 studies reporting on 29 recommendations has found that median adherence to all recommendations was 34%, suggesting that potential benefits for patients from health research may be lost [2].Clinical decision support systems (CDSS) can serve as a knowledge translation tool, mediator between clinical guidelines and physicians by providing the right information to the right person at the right time. To evaluate the effectiveness of implementation of international and national CPGs for venous thromboembolism (VTE) prevention with the help of CDSS in a general hospital. A multifunctional CDSS based on national and international guidelines on the VTE prevention was developed and implemented in the Medical Center of the Bank of Russia (MC). The system has the following functionalities: 1) it supports the decision on the VTE prevention based on individual risk assessment of thrombosis (scales of Caprini, Rogers and Khorana, Padua Prediction Score, additional risk factors) and bleeding (IMPROVE scale for non-surgical patients, major bleeding scale for surgical patients and major orthopedic surgeries, hemorrhagic complications risk in cancer patients); 2) generates the summary containing the grade of recommendations and the level of evidence, personalized recommendations on regimen and duration of preventive antithrombotic therapy, dose correction according to creatinine clearance; 3) provides an audit form for and statistical analysis of VTE cases; 3) automatically generates a quality register for VTE prevention.CDSS was implemented in June 2014. We analyzed VTE cases identified by triggers (deep vein thrombosis diagnosed by Doppler ultrasound and pulmonary embolism at the chest CT) that occurred in 2014 before and after CDSS implementation, as well as in the first half of 2015. Patients with VTE diagnosed during the first 48 hours of hospitalization or receiving anticoagulants in therapeutic doses were excluded from the analysis. Chi-square test for linear trend and non-parametric methods of descriptive statistics were used for data analysis. CDSS utilization was regulated by a special hospital-wide policy; lectures were organized to educate doctors how to use the system. Although international recommendations require VTE risk assessment for all hospitalized patients (except those receiving anticoagulant in therapeutic doses), the doctors filled forms for only 306 patients during the first 6 months of CDSS functioning (14.1% of discharges with length of stay >48 hours during this period). In the first half of 2015 the coverage of VTE risk assessment with CDSS was 19% (n = 506). Correctness of filling out the forms was 78.4%, in the rest of cases doctors made mistakes in choosing patient's profile or when filling in risk scales.Doctors adhere to given recommendations in 85.4% of cases. Most often (47.5%) pharmacotherapy with low molecular weight heparin (LMWH), preventive doses, was recommended by the system, and in this category the adherence to recommended practice was the lowest (74.6%). Among patients who underwent pharmacoprophylaxis, in 21.1% cases the use of anticoagulants was inconsistent with clinical guidelines or drug package insert (typically inappropriate choice of LMWH prophylactic doses, delaying or reducing the duration of prophylaxis).The rate of hospital-acquired VTE significantly decreased after CDSS implementation and was 11.71, 8.28 and 4.84 per 1,000 hospitalizations in the first and second half of 2014 and in the first half of 2015, respectively (χ2 = 7.325, df = 1, p = 0.0068). The rate of postoperative VTE for the same period amounted to 8.76, 3.39 and 4.17 per 1,000 operations, respectively (χ2 = 7.266, df = 1, p = 0.007), reaching a level of the correspondent AHRQ safety indicator (4.99 per 1,000 operations) [3]. Deviations from clinical guidelines or anticoagulant package inserts were revealed in 74% of VTE cases; and more than 1/3 of deviations affected treatment outcomes. Coverage of hospitalized patients with documented VTE risk assessment gradually increased after the CDSS implementation, but remained at a low level (19% of eligible patients). Partly it may be attributed to the lack of CDSS integration in electronic health record or computerized physician order entry systems that would facilitate routine documentation of VTE and bleeding risks. However, the introduction of CDSS has allowed reducing significantly the rate of hospital-acquired VTE. This can be explained by drawing doctor's attention to the VTE problem and by training effect of CDSS. After receiving appropriate recommendations doctors adhere to them, on average, in 85.4% of cases, although for LMWH pharmacoprophylaxis this level was lower (74.6%). Development of hospital-acquired VTE in most cases (74%) was accompanied by non-compliance with CPGs recommendations, emphasizing the importance of additional measures for better adherence to evidence-based clinical practices.

In 2012, the Israel Defense Forces Medical Corps (IDF-MC) set a goal of reducing mortality and eliminating preventable death on the battlefield. A force buildup plan entitled "My Brother's Keeper" was launched addressing: trauma medicine, training, change of Clinical Practice Guidelines (CPGs), injury prevention, data collection, global collaboration and more. The aim of this article is to examine how military medical care has evolved due "My Brother's Keeper" between Second Lebanon War (SLW, 2006) to Operation Protective Edge (OPE, 2014). Records of all casualties during OPE and SLW were extracted and analyzed from the I.D.F Trauma Registry. Noncombat injuries and civilian injuries from missile attacks were excluded from this analysis. The plans main impacts were; incorporation of a physician or paramedic as an integral part of each fighting company, implementation of new CPGs, introduction of new approaches for extremity haemorrhage control and Remote Damage Control Resuscitation at point of injury (POI) using single donor reconstituted freeze dried plasma (25 casualties) and transexamic acid (98 casualties). During OPE, 704 soldiers sustained injuries compared with 833 casualties during SLW. Fatalities were 65 and 119, respectively, cumulating to Case Fatality Rate of 9.2% and 14.3%, respectively. Significant changes in the way the IDF-MC provides combat casualty care have been made in recent years. It is the transformation from concept to doctrine and integration into a structured and Goal-Oriented Casualty Care System, especially POI care that led to the unprecedented survival rates in IDF as shown in this conflict.

The Program for National Disease Management Guidelines (German DM-CPG Program) was established in 2002 by the German Medical Association (umbrella organization of the German Chambers of Physicians) and joined by the Association of the Scientific Medical Societies (AWMF; umbrella organization of more than 150 professional societies) and by the National Association of Statutory Health Insurance Physicians (NASHIP) in 2003. The program provides a conceptual basis for disease management, focusing on high-priority health-care topics and aiming at the implementation of best practice recommendations for prevention, acute care, rehabilitation and chronic care. It is organized by the German Agency for Quality in Medicine, a founding member of the Guidelines International Network (G-I-N). The main objective of the German DM-CPG Program is to establish consensus of the medical professions on evidence-based key recommendations covering all sectors of health-care provision and facilitating the coordination of care for the individual patient through time and across interfaces. Within the last year, DM-CPGs have been published for asthma, chronic obstructive pulmonary disease, type 2 diabetes, and coronary heart disease. In addition, experts from national patient self-help groups have been developing patient guidance based upon the recommendations for health-care providers. The article describes background, methods, and tools of the DM-CPG Program, and is the first of a publication series dealing with innovative recommendations and aspects of the program.

The implementation of a community-based aerobic walking program for mild to moderate knee osteoarthritis (OA): a knowledge translation (KT) randomized controlled trial (RCT): Part I: The Uptake of the Ottawa Panel clinical practice guidelines (CPGs)

PubMed Central

2012-01-01

Background The implementation of evidence based clinical practice guidelines on self-management interventions to patients with chronic diseases is a complex process. A multifaceted strategy may offer an effective knowledge translation (KT) intervention to promote knowledge uptake and improve adherence in an effective walking program based on the Ottawa Panel Evidence Based Clinical Practice Guidelines among individuals with moderate osteoarthritis (OA). Methods A single-blind, randomized control trial was conducted. Patients with mild to moderate (OA) of the knee (n=222) were randomized to one of three KT groups: 1) Walking and Behavioural intervention (WB) (18 males, 57 females) which included the supervised community-based aerobic walking program combined with a behavioural intervention and an educational pamphlet on the benefits of walking for OA; 2) Walking intervention (W) (24 males, 57 females) wherein participants only received the supervised community-based aerobic walking program intervention and the educational pamphlet; 3) Self-directed control (C) (32 males, 52 females) wherein participants only received the educational pamphlet. One-way analyses of variance were used to test for differences in quality of life, adherence, confidence, and clinical outcomes among the study groups at each 3 month assessment during the 12-month intervention period and 6-month follow-up period. Results Short-term program adherence was greater in WB compared to C (p<0.012) after 3 months. No statistical significance (p> 0.05) was observed for long-term adherence (6 to 12 months), and total adherence between the three groups. The three knowledge translation strategies demonstrated equivalent long-term results for the implementation of a walking program for older individuals with moderate OA. Lower dropout rates as well as higher retention rates were observed for WB at 12 and 18 months. Conclusion The additional knowledge translation behavioural component facilitated the implementation of clinical practice guidelines on walking over a short-term period. More studies are needed to improve the long-term walking adherence or longer guidelines uptake on walking among participants with OA. Particular attention should be taken into account related to patient’s characteristic and preference. OA can be managed through the implementation of a walking program based on clinical practice guidelines in existing community-based walking clubs as well as at home with the minimal support of an exercise therapist or a trained volunteer.

Using an expert- and data-driven methodology, we have constructed the first clinical practice guidelines (CPGs) for adult Still's disease (ASD) after complete systematic review (SR) of the literature based upon the Medical Information Network Distribution Service (Minds) procedure. The CPG committee for ASD organized by the Research Team for Autoimmune Diseases, the Research Program for Intractable Disease of the Japanese Ministry of Health, Labour, and Welfare has developed CPG for ASD 2017, according to the procedure proposed by Minds. The CPG development process includes (1) clarification of the purpose of CPG, (2) organization of the steering committee, (3) organization of the CPG committee and secretariat, (4) defining the scope (setting of clinical questions (CQs)), (5) SR, (6) development of recommendations, (7) drafting the CPG, (8) external evaluation and public comments, and (9) release. Because we wanted to construct CPG for ASD to encompass both adult-onset Still's disease (AOSD) and adult patients with systemic juvenile idiopathic arthritis (sJIA), we also included SR data from sJIA in this study. Twenty-six CQs were selected and roughly divided into the following items: (1) clinical findings (CQs 1-4), (2) laboratory findings (CQs 5-8), (3) complications (CQs 9-13), (4) treatment with oral medicine (CQs 14-19), (5) treatment with biological reagents (CQs 20-23), and (6) treatments for sJIA (CQs 25-26). Recommendations and the strength of the recommendations for these CQs were decided by a modified Delphi method. We have developed the first published CPG for ASD including AOSD and sJIA, which includes 26 CQs and recommendations. This guideline will help rheumatologists, non-specialized physicians, other healthcare providers, medical and health-related students, and patients and their family members to understand and treat ASD.

Implementing clinical practice guidelines (CPGs) in healthcare settings is a complex intervention involving both independent and interdependent components. Although the Consolidated Framework for Implementation Research (CFIR) has never been evaluated in a practical context, it appeared to be a suitable theoretical framework to guide an implementation process. The aim of this study was to evaluate the comprehensiveness, applicability and usefulness of the CFIR in the implementation of a fall-prevention CPG in nursing practice to improve patient care in an Austrian university teaching hospital setting. The evaluation of the CFIR was based on (1) team-meeting minutes, (2) the main investigator's research diary, containing a record of a before-and-after, mixed-methods study design embedded in a participatory action research (PAR) approach for guideline implementation, and (3) an analysis of qualitative and quantitative data collected from graduate and assistant nurses in two Austrian university teaching hospital departments. The CFIR was used to organise data per and across time point(s) and assess their influence on the implementation process, resulting in implementation and service outcomes. Overall, the CFIR could be demonstrated to be a comprehensive framework for the implementation of a guideline into a hospital-based nursing practice. However, the CFIR did not account for some crucial factors during the planning phase of an implementation process, such as consideration of stakeholder aims and wishes/needs when implementing an innovation, pre-established measures related to the intended innovation and pre-established strategies for implementing an innovation. For the CFIR constructs reflecting & evaluating and engaging, a more specific definition is recommended. The framework and its supplements could easily be used by researchers, and their scope was appropriate for the complexity of a prospective CPG-implementation project. The CFIR facilitated qualitative data analysis and provided a structure that allowed project results to be organised and viewed in a broader context to explain the main findings. The CFIR was a valuable and helpful framework for (1) the assessment of the baseline, process and final state of the implementation process and influential factors, (2) the content analysis of qualitative data collected throughout the implementation process, and (3) explaining the main findings.

Despite American Academy of Orthopaedic Surgeons Clinical Practice Guidelines (CPGs) related to the non-arthroplasty management of osteoarthritis (OA) of the knee, non-recommended treatments remain in common use. We sought to determine the costs associated with non-arthroplasty management of knee OA in the year prior to total knee arthroplasty (TKA) and stratify them by CPG recommendation status. The Humana database was reviewed from 2007 to 2015 for primary TKA patients. Costs for hyaluronic acid (HA) and corticosteroid injections, physical therapy, braces, wedge insoles, opioids, non-steroidal anti-inflammatories, and tramadol in the year prior to TKA were calculated. Cost was defined as reimbursement paid by the insurance provider. Costs were analyzed relative to the overall non-inpatient costs for knee OA and categorized based on CPG recommendations. In total 86,081 primary TKA patients were analyzed and 65.8% had at least one treatment in the year prior to TKA. Treatments analyzed made up 57.6% of the total non-inpatient cost of knee OA in the year prior to TKA. Only 3 of the 8 treatments studied have a strong recommendation for their use (physical therapy, non-steroidal anti-inflammatories, tramadol) and costs for these interventions represented 12.2% of non-inpatient knee OA cost. In contrast, 29.3% of the costs are due to HA injections alone, which are not supported by CPGs. In the year prior to TKA, over half of the non-inpatient costs associated with knee OA are from injections, therapy, prosthetics, and prescriptions. Approximately 30% of this is due to HA injections alone. If only interventions recommend by the CPG are utilized then costs associated with knee OA could be decreased by 45%.

Aortic aneurysm (AA) is a pathology with high morbidity and mortality. The management can be expectant, surgical, or through endovascular repair (EVAR). In Latin America the incidence of AA has increased and the analysis of therapeutic options, especially if they are expensive, is fundamental. To analyze available evidence on the effectiveness, safety and coverage policies of the EVAR. Panoramic review in the main bibliographical bases (MEDLINE, LILACS, EMBASE, Cochrane Library, DARE) and generic internet searchers, main health technology assessment (HTA) agencies and health insurance companies. Systematic reviews (SR), clinical practice guidelines (CPG), HTA and coverage policies, followed by the identification of primary studies published after the SR search date were included. A search of studies published until November 2015 in English and Spanish was carried out. 311 references were recovered, from which seven SRs were selected, one clinical study and 15 CPGs, consensus or coverage policies and ETS. For abdominal AA, high quality evidence showed no differences inlong-term survival with the use of EVAR compared to conventional surgery, but lower early mortality was observed (OR = 0.33, 95% CI 0.20 -0.55). EVAR was associated with a greater need for re-intervention. In the case of other types of AA, further evidence is still required to establish the benefit of EVAR. The CPGs, consensus, HTAs and coverage policies identified, mostly consider open surgery as the treatment of choice, reserving the EVAR for patients with high surgical risk for conventional surgery in the presence of favorable anatomy.

Anxiety is a common mental health problem seen in primary care. However, its management in clinical practice varies greatly. Clinical practice guidelines (CPGs) have the potential to reduce variations and improve the care received by patients by promoting interventions of proven benefit. However, uptake and adherence to their recommendations can be low. This study involves a community based on cluster randomized trial in primary healthcare centres in the Madrid Region (Spain). The project aims to determine whether the use of implementation strategy (including training session, information, opinion leader, reminders, audit, and feed-back) of CPG for patients with anxiety disorders in primary care is more effective than usual diffusion. The number of patients required is 296 (148 in each arm), all older than 18 years and diagnosed with generalized anxiety disorder, panic disorder, and panic attacks by the Diagnostic and Statistical Manual of Mental Disorders-IV (DSM-IV). They are chosen by consecutive sampling. The main outcome variable is the change in two or more points into Goldberg anxiety scale at six and twelve months. Secondary outcome variables include quality of life (EuroQol 5D), and degree of compliance with the CPG recommendations on treatment, information, and referrals to mental health services. Main effectiveness will be analyzed by comparing the patients percentage improvement on the Goldberg scale between the intervention group and the control group. Logistic regression with random effects will be used to adjust for prognostic factors. Confounding factors or factors that might alter the effect recorded will be taken into account in this analysis. There is a need to identify effective implementation strategies for CPG for the management of anxiety disorders present in primary care. Ensuring the appropriate uptake of guideline recommendations can reduce clinical variation and improve the care patients receive. ISRCTN: ISRCTN83365316.

Cancer predisposition genes (CPGs) are genes in which inherited mutations confer highly or moderately increased risks of developing cancer. Identification of these genes and understanding the biological mechanisms that underlie them is crucial for the prevention, early diagnosis, and optimized management of cancer. Over the past decades, great efforts have been made to identify CPGs through multiple strategies. However, information on these CPGs and their molecular functions is scattered. To address this issue and provide a comprehensive resource for researchers, we developed the Cancer Predisposition Gene Database (dbCPG, Database URL: http://bioinfo.ahu.edu.cn:8080/dbCPG/index.jsp), the first literature-based gene resource for exploring human CPGs. It contains 827 human (724 protein-coding, 23 non-coding, and 80 unknown type genes), 637 rats, and 658 mouse CPGs. Furthermore, data mining was performed to gain insights into the understanding of the CPGs data, including functional annotation, gene prioritization, network analysis of prioritized genes and overlap analysis across multiple cancer types. A user-friendly web interface with multiple browse, search, and upload functions was also developed to facilitate access to the latest information on CPGs. Taken together, the dbCPG database provides a comprehensive data resource for further studies of cancer predisposition genes.

In utero arsenic exposure may alter fetal developmental programming by altering DNA methylation, which may result in a higher risk of disease in later life. We evaluated the association between in utero arsenic exposure and DNA methylation (DNAm) in cord blood and its influence in later life. Genome-wide DNA methylation in cord blood from 64 subjects in the Taiwanese maternal infant and birth cohort was analyzed. Robust regressions were applied to assess the association of DNA methylation with in utero arsenic exposure. Multiple testing was adjusted by controlling false discovery rate (FDR) of 0.05. The DAVID bioinformatics tool was implemented for functional annotation analyses on the detected CpGs. The identified CpGs were further tested in an independent cohort. For the CpGs replicated in the independent cohort, linear mixed models were applied to assess the association of DNA methylation with low-density lipoprotein (LDL) at different ages (2, 5, 8, 11 and 14 years). In total, 579 out of 385,183 CpGs were identified after adjusting for multiple testing (FDR = 0.05), of which ~60% were positively associated with arsenic exposure. Functional annotation analysis on these CpGs detected 17 KEGG pathways (FDR = 0.05) including pathways for cardiovascular diseases (CVD) and diabetes mellitus. In the independent cohort, about 46% (252 out of 553 CpGs) of the identified CpGs showed associations consistent with those in the study cohort. In total, 11 CpGs replicated in the independent cohort were in the pathways related to CVD and diabetes mellitus. Via longitudinal analyses, we found at 5 out of the 11 CpGs methylation was associated with LDL over time and interactions between DNA methylation and time were observed at 4 of the 5 CpGs, cg25189764 (coeff = 0.157, p-value = 0.047), cg04986899 (coeff. For interaction [coeff.int] = 0.030, p-value = 0.024), cg04903360 (coeff.int = 0.026, p-value = 0.032), cg08198265 (coeff.int = -0.063, p-value = 0.0021), cg10473311 (coeff.int = -0.021, p-value = 0.027). In utero arsenic exposure was associated with cord blood DNA methylation at various CpGs. The identified CpGs may help determine pathological epigenetic mechanisms linked to in utero arsenic exposure. Five CpGs (cg25189764, cg04986899, cg04903360, cg08198265 and cg10473311) may serve as epigenetic markers for changes in LDL later in life.

Lipid-lowering drugs in ischaemic heart disease: A quasi-experimental uncontrolled before-and-after study of the effectiveness of clinical practice guidelines

PubMed Central

2011-01-01

Background Cardiovascular diseases(CVD), specifically ischaemic heart disease(IHD), are the main causes of death in industrialized countries. Statins are not usually prescribed in the most appropriate way. To ensure the correct prescription of these drugs, it is necessary to develop, disseminate and implement clinical practice guidelines(CPGs), and subsequently evaluate them. The main objective of this study is to evaluate the effectiveness of the implementation of consensual Lipid-lowering drugs (LLD) prescription guidelines in hospital and primary care settings, to improve the control of Low-Density Lipoprotein Cholesterol (LDL-C) levels in patients with IHD in the Terres de l'Ebre region covered by the Catalonian Health Institute. Secondary objectives are to assess the improvement of the prescription profile of these LLDs, to assess cardiovascular morbimortality and the professional profile and participant centre characteristics that govern the control of LDL-C. Methods/Design Design: Quasi-experimental uncontrolled before and after study. The intervention consists of the delivery of training strategies for guideline implementation (classroom clinical sessions and on-line courses) aimed at primary care and hospital physicians. The improvement in the control of LDL-C levels in the 3,402 patients with IHD in our territory is then assessed. Scope: Primary care physicians from 11 basic health areas(BHAs) and two hospital services (internal medicine and cardiology). Sample: 3,402 patients registered with IHD in the database of the Catalan Institute of Health(E-cap) before December 2008 and patients newly diagnosed during 2009-2010. Variables: Percentage of patients achieving good control of LDL-C, measured in milligrams per decilitre. The aim of the intervention is to achieve levels of LDL-C < 100 mg/dl in patients with IHD. Secondary variables measure type and time of diagnosis of IHD, type and dose of prescribed cholesterol-lowering drugs, level of physician participation in training activities and their professional profile. Discussion The development of prescription guidelines previously agreed by various medical specialists involved in treating IHD patients have usually improved drug prescription. The guideline presented in this study aims to improve the control of LDL-C by training physicians through presential and on-line courses on the dissemination of this guideline, and by providing feedback on their personal results a year after this training intervention.

Despite growing interest in the importance of, and challenges associated with the involvement of patient and population (IPP) in the process of developing and adapting clinical practice guidelines (CPGs), there is a lack of knowledge about the best method to use. This is especially problematic in the field of rehabilitation, where individuals with disabilities might face many barriers to their involvement in the guideline development and adaptation process. The goal of this pilot trial is to document the acceptability, feasibility and effectiveness of two methods of involving patients with a disability (traumatic brain injury) in CPG development. A single-blind, randomized, crossover pragmatic trial will be performed with 20 patients with traumatic brain injury (TBI). They will be randomized into two groups, and each will try two alternative methods of producing recommendations; a discussion group (control intervention) and a Wiki, a webpage that can be modified by those who have access to it (experimental intervention). The participants will rate the acceptability of the two methods, and feasibility will be assessed using indicators such as the number of participants who accessed and completed the two methods, and the number of support interventions required. Twenty experts, blinded to the method of producing the recommendations, will independently rate the recommendations produced by the participants for clarity, accuracy, appropriateness and usefulness. Our trial will allow for the use of optimal IPP methods in a larger project of adapting guidelines for the rehabilitation of individuals with TBI. Ultimately the results will inform the science of CPG development and contribute to the growing knowledge about IPP in rehabilitation settings. Clinical trial KT Canada 87776.

Conductive polymers have attracted significant interest over the past few decades because they synergize the advantageous features of conventional polymeric materials and organic conductors. With rationally designed nanostructures, conductive polymers can further exhibit exceptional mechanical, electrical, and optical properties because of their confined dimensions at the nanoscale level. Among various nanostructured conductive polymers, conductive polymer gels (CPGs) with synthetically tunable hierarchical 3D network structures show great potential for a wide range of applications, such as bioelectronics, and energy storage/conversion devices owing to their structural features. CPGs retain the properties of nanosized conductive polymers during the assembly of the nanobuilding blocksmore » into a monolithic macroscopic structure while generating structure-derived features from the highly cross-linked network. In this Account, we review our recent progress on the synthesis, properties, and novel applications of dopant cross-linked CPGs. We first describe the synthetic strategies, in which molecules with multiple functional groups are adopted as cross-linkers to cross-link conductive polymer chains into a 3D molecular network. These cross-linking molecules also act as dopants to improve the electrical conductivity of the gel network. The microstructure and physical/chemical properties of CPGs can be tuned by controlling the synthetic conditions such as species of monomers and cross-linkers, reaction temperature, and solvents. By incorporating other functional polymers or particles into the CPG matrix, hybrid gels have been synthesized with tailored structures. These hybrid gel materials retain the functionalities from each component, as well as enable synergic effects to improve mechanical and electrical properties of CPGs. We then introduce the unique structure-derived properties of the CPGs. The network facilitates both electronic and ionic transport owing to the continuous pathways for electrons and hierarchical pores for ion diffusion. CPGs also provide high surface area and solvent compatibility, similar to natural gels. With these improved properties, CPGs have been explored to enable novel conceptual devices in diverse applications from smart electronics and ultrasensitive biosensors, to energy storage and conversion devices. CPGs have also been adopted for developing hybrid materials with multifunctionalities, such as stimuli responsiveness, self-healing properties, and super-repellency to liquid. With synthetically tunable physical/chemical properties, CPGs emerge as a unique material platform to develop novel multifunctional materials that have the potential to impact electronics, energy, and environmental technologies.

The aim of this study was to survey the selection, use, and maintenance of chemical protective gloves (CPGs) at real workplaces. Subjects comprised 817 workers using CPGs at seven domestic manufacturing plants in Japan. We administered an anonymous questionnaire survey comprising the following aspect related to CPGs: environment of use, conditions of use, method of selection, knowledge/awareness pertaining to their use, method of use, precautionary measures associated with their use, maximum time of use, and maintenance. We compared responses provided by management staff and field workers. Chi square test was used for the analysis. Respondents included 661 (80.9%) manufacturing workers, 121 (14.8%) managers or supervisors, and 35 (4.3%) others. In total, 70.5% organic solvents, 28.9% acid or/and alkali, 18.1% dust, and 10.3% carcinogenic substances were the chemical substances handled using CPGs. The reason for deciding to wear CPGs was "the use of chemical substances" for 46.5%, "notice in safety data sheet (SDS) " for 29.8%, and "management staffs' guidance" for 21.4% respondents. "The grasp of chemical substances" was 70.1% (91.1% excluding "not applicable" ). "Warning of caution on skin and eyes" was indicated by 69.5% (91.0%) and "educational reasons for use of CPGs" was accepted by 68.1% (90.7%) respondents. On the other hand, the rate of responses such as "obtaining permeability test results of target substances" and "mixed substances are selected considering substances with short permeation time" was 25.2% (38.4%) and 29.2% (48.4%), respectively. The rate of "yes" as a response in the item concerning "permeation test" was low. On comparing the response provided by the management staff and field workers, the rate of "the permeation test result of the target substance was obtained" was 27.7% for management staff and 41.2% for field workers (p = 0.022). Regarding the cuffs of CPGs, the rate of "to fold back and to prevent sagging" and "mounted with tape" were 30.5% and 21.8% for management staff and 50.2% and 42.2% for field workers (p = 0.001 and p = 0.001), respectively. This survey results suggested that the knowledge of "permeation test" of CPGs was not yet popular at industrial workplaces. It is necessary to disseminate knowledge related to "permeation test" to the users from manufacturers of CPGs. Additionally, the employer should appoint an administrator to ensure that CPGs are worn and increase the understanding of correct knowledge and usage of CPGs among workers.

Development of these guidelines is mandated by the American Association of Clinical Endocrinologists (AACE) Board of Directors and the American College of Endocrinology (ACE) Board of Trustees and adheres to published AACE protocols for the standardized production of clinical practice guidelines (CPGs). Recommendations are based on diligent review of clinical evidence with transparent incorporation of subjective factors. There are 9 broad clinical questions with 123 recommendation numbers that include 160 specific statements (85 [53.1%] strong [Grade A], 48 [30.0%] intermediate [Grade B], and 11 [6.9%] weak [Grade C], with 16 [10.0%] based on expert opinion [Grade D]) that build a comprehensive medical care plan for obesity. There were 133 (83.1%) statements based on strong (best evidence level [BEL] 1 = 79 [49.4%]) or intermediate (BEL 2 = 54 [33.7%]) levels of scientific substantiation. There were 34 (23.6%) evidence-based recommendation grades (Grades A-C = 144) that were adjusted based on subjective factors. Among the 1,788 reference citations used in this CPG, 524 (29.3%) were based on strong (evidence level [EL] 1), 605 (33.8%) were based on intermediate (EL 2), and 308 (17.2%) were based on weak (EL 3) scientific studies, with 351 (19.6%) based on reviews and opinions (EL 4). The final recommendations recognize that obesity is a complex, adiposity-based chronic disease, where management targets both weight-related complications and adiposity to improve overall health and quality of life. The detailed evidence-based recommendations allow for nuanced clinical decision-making that addresses real-world medical care of patients with obesity, including screening, diagnosis, evaluation, selection of therapy, treatment goals, and individualization of care. The goal is to facilitate high-quality care of patients with obesity and provide a rational, scientific approach to management that optimizes health outcomes and safety.

The Human Central Pattern Generator for Locomotion.

2017-03-01

The ability of dedicated spinal circuits, referred to as central pattern generators (CPGs), to produce the basic rhythm and neural activation patterns underlying locomotion can be demonstrated under specific experimental conditions in reduced animal preparations. The existence of CPGs in humans is a matter of debate. Equally elusive is the contribution of CPGs to normal bipedal locomotion. To address these points, we focus on human studies that utilized spinal cord stimulation or pharmacological neuromodulation to generate rhythmic activity in individuals with spinal cord injury, and on neuromechanical modeling of human locomotion. In the absence of volitional motor control and step-specific sensory feedback, the human lumbar spinal cord can produce rhythmic muscle activation patterns that closely resemble CPG-induced neural activity of the isolated animal spinal cord. In this sense, CPGs in humans can be defined by the activity they produce. During normal locomotion, CPGs could contribute to the activation patterns during specific phases of the step cycle and simplify supraspinal control of step cycle frequency as a feedforward component to achieve a targeted speed. Determining how the human CPGs operate will be essential to advance the theory of neural control of locomotion and develop new locomotor neurorehabilitation paradigms.

Numerous studies have elucidated the genetics of Parkinson's disease; however, the aetiology of the majority of sporadic cases has not yet been resolved. We hypothesized that epigenetic variations could be associated with PD and evaluated the DNA methylation pattern in PD patients compared to brothers or twins without PD. The methylation of DNA from peripheral blood mononuclear cells of 62 discordant siblings including 24 monozygotic twins was characterized with Illumina DNA Methylation 450K bead arrays and subsequently validated in two independent cohorts: 221 PD vs. 227 healthy individuals (cohort 1) applying Illumina's VeraCode and 472 PD patients vs. 487 controls (cohort 2) using pyrosequencing. We choose a delta beta of >15 % and selected 62 differentially methylated CpGs in 51 genes from the discordant siblings. Among them, three displayed multiple CpGs per gene: microRNA 886 (MIR886, 10 CpGs), phosphodiesterase 4D (PDE4D, 2 CpGs) and tripartite motif-containing 34 (TRIM34, 2 CpGs). PDE4D was confirmed in both cohorts (p value 2.44e-05). In addition, for biomarker construction, we used the penalized logistic regression model, resulting in a signature of eight CpGs with an AUC of 0.77. Our findings suggest that a distinct level of PD susceptibility stems from individual, epigenetic modifications of specific genes. We identified a signature of CpGs in blood cells that could separate control from disease with a reasonable discriminatory power, holding promise for future epigenetically based biomarker development.

Background: Previous research supports the claim that managers are vital players in the implementation of clinical practice guidelines (CPGs), yet little is known about interventions aiming to develop managers’ leadership in facilitating implementation. In this pilot study, process evaluation was employed to study the feasibility and usefulness of a leadership intervention by exploring the intervention’s potential to support managers in the implementation of national guideline recommendations for stroke care in outpatient rehabilitation. Methods: Eleven senior and frontline managers from five outpatient stroke rehabilitation centers participated in a four-month leadership intervention that included workshops, seminars, and teleconferences. The focus was on developing knowledge and skills to enhance the implementation of CPG recommendations, with a particular focus on leadership behaviors. Each dyad of managers was assigned to develop a leadership plan with specific goals and leadership behaviors for implementing three rehabilitation recommendations. Feasibility and usefulness were explored through observations and interviews with the managers and staff members prior to the intervention, and then one month and one year after the intervention. Results: Managers considered the intervention beneficial, particularly the participation of both senior and frontline managers and the focus on leadership knowledge and skills for implementing CPG recommendations. All the managers developed a leadership plan, but only two units identified goals specific to implementing the three stroke rehabilitation recommendations. Of these, only one identified leadership behaviors that support implementation. Conclusion: Managers found that the intervention was delivered in a feasible way and appreciated the focus on leadership to facilitate implementation. However, the intervention appeared to have limited impact on managers’ behaviors or clinical practice at the units. Future interventions directed towards managers should have a stronger focus on developing leadership skills and behaviors to tailor implementation plans and support implementation of CPG recommendations.

In 2012, comprehensive clinical practice guidelines (CPGs) were published regarding the management of hypothyroidism. We sought to document current practices in the management of primary hypothyroidism and compare these results with recommendations made in the 2012 American Thyroid Association (ATA)/American Association of Clinical Endocrinologists (AACE) hypothyroidism CPGs. In addition, we sought to examine differences in management among international members of U.S.-based endocrine societies and to compare survey results with those obtained from a survey of ATA members performed 12 years earlier. Clinical members of The Endocrine Society (TES), the ATA, and the AACE were asked to take a web-based survey consisting of 30 questions dealing with testing, treatment, and modulating factors in the management of primary hypothyroidism. In total, 880 respondents completed the survey, including 618 members of TES, 582 AACE members, and 208 ATA members. North American respondents accounted for 67.6%, Latin American 9.7%, European 9.2%, Asia and Oceania 8.1%, and Africa and Middle East 5.5%. Overt hypothyroidism would be treated using l-T4 alone by 99.2% of respondents; 0.8% would use combination l-T4 and liothyronine (l-T3) therapy. Generic l-T4 would be used by 49.3% and a brand name by 49.9%. The rate of replacement would be gradual (38.5%); an empiric dose, adjusted to achieve target (33.6%); or a calculated full replacement dose (27.8%). A target TSH of 1.0 to 1.9 mU/L was favored in the index case, but 3.0 to 3.9 mU/L was the most commonly selected TSH target for an octogenarian. Persistent hypothyroid symptoms despite achieving a target TSH would prompt testing for other causes by 84.3% of respondents, a referral to primary care by 11.3%, and a change to l-T4 plus l-T3 therapy by 3.6%. Evaluation of persistent symptoms would include measurement of T3 levels by 21.9% of respondents. Subclinical disease with a TSH 5.0 to 10.0 mU/L would be treated without further justification by 21.3% of respondents, or in the presence of positive thyroid peroxidase antibodies (62.3%), hypothyroid symptoms (60.9%), high low-density lipoprotein (52.9%), or goiter (46.6%). The TSH target for a newly pregnant patient was <2.5 mU/L for 96.1% of respondents, with 63.5% preferring a TSH target <1.5 mU/L. Thyroid hormone levels would be checked every 4 weeks during pregnancy by 67.7% and every 8 weeks by an additional 21.4%. A hypothyroid patient with TSH of 0.5 mU/L who becomes pregnant would receive an immediate l-T4 dose increase by only 36.9% of respondents. The current survey of clinical endocrinologists catalogs current practice patterns in the management of hypothyroidism and demonstrates 1) a nearly exclusive preference for l-T4 alone as initial therapy, 2) the widespread use of age-specific TSH targets for replacement therapy, 3) a low threshold for treating mild thyroid failure, 4) meticulous attention to TSH targets in the pregnant and prepregnant woman, and 5) a highly variable approach to both the rate and means of restoring euthyroidism for overt disease. Both alignment and focal divergence from recent CPGs are demonstrated.

Several articles describe highly accurate age estimation methods based on human DNA-methylation data. It is not yet known whether similar epigenetic aging clocks can be developed based on blood methylation data from canids. Using Reduced Representation Bisulfite Sequencing, we assessed blood DNA-methylation data from 46 domesticated dogs ( Canis familiaris ) and 62 wild gray wolves ( C. lupus ). By regressing chronological dog age on the resulting CpGs, we defined highly accurate multivariate age estimators for dogs (based on 41 CpGs), wolves (67 CpGs), and both combined (115 CpGs). Age related DNA methylation changes in canids implicate similar gene ontology categories as those observed in humans suggesting an evolutionarily conserved mechanism underlying age-related DNA methylation in mammals.

To succeed, pregnancies need to initiate immune biases towards T helper 2 (Th2) responses, yet little is known about what establishes this bias. Using the Illumina 450 K platform, we explored changes in DNA methylation (DNAm) of Th1, Th2, Th17, and regulatory T cell pathway genes before and during pregnancy. Female participants were recruited at birth (1989), and followed through age 18 years and their pregnancy (2011–2015). Peripheral blood DNAm was measured in 245 girls at 18 years; from among these girls, the DNAm of 54 women was repeatedly measured in the first (weeks 8–21, n = 39) and second (weeks 22–38, n = 35) halves of pregnancy, respectively. M-values (logit-transformed β-values of DNAm) were analyzed: First, with repeated measurement models, cytosine–phosphate–guanine sites (CpGs) of pathway genes in pregnancy and at age 18 (nonpregnant) were compared for changes (p ≤ 0.05). Second, we tested how many of the 348 pathway-related CpGs changed compared to 10 randomly selected subsets of all other CpGs and compared to 10 randomly selected subsets of other CD4+-related CpGs (348 in each subset). Contrasted to the nonpregnant state, 27.7% of Th1-related CpGs changed in the first and 36.1% in the second half of pregnancy. Among the Th2 pathway CpGs, proportions of changes were 35.1% (first) and 33.8% (second half). The methylation changes suggest involvement of both Th1 and Th2 pathway CpGs in the immune bias during pregnancy. Changes in regulatory T cell and Th17 pathways need further exploration.

Current clinical practice guidelines (CPGs) for posttraumatic stress disorder (PTSD) offer contradictory recommendations regarding use of medications or psychotherapy as first-line treatment. Direct head-to-head comparisons are lacking. Systemic review of Medline, EMBASE, PILOTS, Cochrane Central Register of Controlled Trials, PsycINFO, and Global Health Library was conducted without language restrictions. Randomized clinical trials ≥8 weeks in duration using structured clinical interview-based outcome measures, active-control conditions (e.g. supportive psychotherapy), and intent-to-treat analysis were selected for analyses. Independent review, data abstraction, and bias assessment were performed using standardized processes. Study outcomes were grouped around conventional follow-up time periods (3, 6, and 9 months). Combined effect sizes were computed using meta-analyses for medication versus control, medication pre-/posttreatment, psychotherapy versus control, and psychotherapy pre-/posttreatment. Effect sizes for trauma-focused psychotherapies (TFPs) versus active control conditions were greater than medications versus placebo and other psychotherapies versus active controls. TFPs resulted in greater sustained benefit over time than medications. Sertraline, venlafaxine, and nefazodone outperformed other medications, although potential for methodological biases were high. Improvement following paroxetine and fluoxetine treatment was small. Venlafaxine and stress inoculation training (SIT) demonstrated large initial effects that decreased over time. Bupropion, citalopram, divalproex, mirtazapine, tiagabine, and topiramate failed to differentiate from placebo. Aripiprazole, divalproex, guanfacine, and olanzapine failed to differentiate from placebo when combined with an antidepressant. Study findings support use of TFPs over nontrauma-focused psychotherapy or medication as first-line interventions. Second-line interventions include SIT, and potentially sertraline or venlafaxine, rather than entire classes of medication, such as SSRIs. Future revisions of CPGs should prioritize studies that utilize active controls over waitlist or treatment-as-usual conditions. Direct head-to-head trials of TFPs versus sertraline or venlafaxine are needed. © 2016 Wiley Periodicals, Inc.

Splenic preservation is the standard of care for hemodynamically stable children with splenic injuries. We report a 20-year single-institutional series of children with splenic injuries managed without a splenectomy. Children evaluated and treated for blunt splenic injury at Boston Children's Hospital from 1994 to 2014 were extracted from the trauma registry. Demographics, clinical characteristics, complications, and outcomes were reviewed. Three time-periods were evaluated based upon the development and modification of splenic injury clinical pathway guidelines (CPGs). Survival was defined as being discharged from the hospital alive. 502 suffered isolated splenic injuries. The median AAST grade of splenic injury increased across the three CPG time periods (p<0.001). No splenic-injury related mortalities occurred. Hospital length of stay decreased significantly secondary to splenic injury CPGs (p<0.001). 99% of the patients were discharged home. In children managed over the last 20years for isolated splenic injury, no patient died or underwent splenectomy. Hospital length of stay decreased across time, despite an increase in the severity of splenic injuries encountered. Splenectomy has become so unusual in the management of hemodynamically stable children with a splenic injury that it may no longer be a legitimate outcome marker. Copyright © 2015 Elsevier Inc.

Evidence-based clinical practice guidelines (CPGs) are statements that provide recommendations to optimize patient care for a specific clinical problem or question. Merely reading a guideline rarely leads to implementation of recommendations. The American Academy of Neurology (AAN) has a formal process of guideline development and dissemination. The last few years have seen a burgeoning of social media such as Facebook, Twitter, and LinkedIn, and newer methods of dissemination such as podcasts and webinars. The role of these media in guideline dissemination has not been studied. Systematic evaluation of dissemination methods and comparison of the effectiveness of newer methods with traditional methods is not available. It is also not known whether specific dissemination methods may be more effectively targeted to specific audiences. Our aim was to (1) develop an innovative dissemination strategy by adding social media-based dissemination methods to traditional methods for the AAN clinical practice guidelines "Complementary and alternative medicine in multiple sclerosis" ("CAM in MS") and (2) evaluate whether the addition of social media outreach improves awareness of the CPG and knowledge of CPG recommendations, and affects implementation of those recommendations. Outcomes were measured by four surveys in each of the two target populations: patients and physicians/clinicians ("physicians"). The primary outcome was the difference in participants' intent to discuss use of complementary and alternative medicine (CAM) with their physicians or patients, respectively, after novel dissemination, as compared with that after traditional dissemination. Secondary outcomes were changes in awareness of the CPG, knowledge of CPG content, and behavior regarding CAM use in multiple sclerosis (MS). Response rates were 25.08% (622/2480) for physicians and 43.5% (348/800) for patients. Awareness of the CPG increased after traditional dissemination (absolute difference, 95% confidence interval: physicians 36%, 95% CI 25-46, and patients 10%, 95% CI 1-11) but did not increase further after novel dissemination (physicians 0%, 95% CI -11 to 11, and patients -4%, 95% CI -6 to 14). Intent to discuss CAM also increased after traditional dissemination but did not change after novel dissemination (traditional: physicians 12%, 95% CI 2-22, and patients 19%, 95% CI 3-33; novel: physicians 11%, 95% CI -1 to -21, and patients -8%, 95% CI -22 to 8). Knowledge of CPG recommendations and behavior regarding CAM use in MS did not change after either traditional dissemination or novel dissemination. Social media-based dissemination methods did not confer additional benefit over print-, email-, and Internet-based methods in increasing CPG awareness and changing intent in physicians or patients. Research on audience selection, message formatting, and message delivery is required to utilize Web 2.0 technologies optimally for dissemination.

Background Studies in animal models and in cultured cells have shown that fatty acids can induce alterations in the DNA methylation of specific genes. There have been no studies of the effects of fatty acid supplementation on the epigenetic regulation of genes in adult humans. Methods and Results We investigated the effect of supplementing renal patients with 4 g daily of either n-3 long-chain polyunsaturated fatty acids (n-3 LCPUFA) or olive oil (OO) for 8 weeks on the methylation status of individual CpG loci in the 5′ regulatory region of genes involved in PUFA biosynthesis in peripheral blood mononuclear cells from men and women (aged 53 to 63 years). OO and n-3 LCPUFA each altered (>10% difference in methylation) 2/22 fatty acid desaturase (FADS)-2 CpGs, while n-3 LCPUFA, but not OO, altered (>10%) 1/12 ELOVL5 CpGs in men. OO altered (>6%) 8/22 FADS2 CpGs and (>3%) 3/12 elongase (ELOVL)-5 CpGs, while n-3 LCPUFA altered (>5%) 3/22 FADS2 CpGs and 2/12 (>3%) ELOVL5 CpGs in women. FADS1 or ELOVL2 methylation was unchanged. The n-3 PUFA supplementation findings were replicated in blood DNA from healthy adults (aged 23 to 30 years). The methylation status of the altered CpGs in FADS2 and ELOVL5 was associated negatively with the level of their transcripts. Conclusions These findings show that modest fatty acid supplementation can induce altered methylation of specific CpG loci in adult humans, contingent on the nature of the supplement and on sex. This has implications for understanding the effect of fatty acids on PUFA metabolism and cell function. PMID:25329159

Recently, it has been proposed that epigenetic variation may contribute to the risk of complex genetic diseases like cancer. We aimed to demonstrate that epigenetic changes in normal cells, collected years in advance of the first signs of morphological transformation, can predict the risk of such transformation. We analyzed DNA methylation (DNAm) profiles of over 27,000 CpGs in cytologically normal cells of the uterine cervix from 152 women in a prospective nested case-control study. We used statistics based on differential variability to identify CpGs associated with the risk of transformation and a novel statistical algorithm called EVORA (Epigenetic Variable Outliers for Risk prediction Analysis) to make predictions. We observed many CpGs that were differentially variable between women who developed a non-invasive cervical neoplasia within 3 years of sample collection and those that remained disease-free. These CpGs exhibited heterogeneous outlier methylation profiles and overlapped strongly with CpGs undergoing age-associated DNA methylation changes in normal tissue. Using EVORA, we demonstrate that the risk of cervical neoplasia can be predicted in blind test sets (AUC = 0.66 (0.58 to 0.75)), and that assessment of DNAm variability allows more reliable identification of risk-associated CpGs than statistics based on differences in mean methylation levels. In independent data, EVORA showed high sensitivity and specificity to detect pre-invasive neoplasia and cervical cancer (AUC = 0.93 (0.86 to 1) and AUC = 1, respectively). We demonstrate that the risk of neoplastic transformation can be predicted from DNA methylation profiles in the morphologically normal cell of origin of an epithelial cancer. Having profiled only 0.1% of CpGs in the human genome, studies of wider coverage are likely to yield improved predictive and diagnostic models with the accuracy needed for clinical application. The ARTISTIC trial is registered with the International Standard Randomised Controlled Trial Number ISRCTN25417821.

Educational attainment is a key behavioural measure in studies of cognitive and physical health, and socioeconomic status. We measured DNA methylation at 410,746 CpGs (N = 4152) and identified 58 CpGs associated with educational attainment at loci characterized by pleiotropic functions shared with neuronal, immune and developmental processes. Associations overlapped with those for smoking behaviour, but remained after accounting for smoking at many CpGs: Effect sizes were on average 28% smaller and genome-wide significant at 11 CpGs after adjusting for smoking and were 62% smaller in never smokers. We examined sources and biological implications of education-related methylation differences, demonstrating correlations with maternal prenatal folate, smoking and air pollution signatures, and associations with gene expression in cis, dynamic methylation in foetal brain, and correlations between blood and brain. Our findings show that the methylome of lower-educated people resembles that of smokers beyond effects of their own smoking behaviour and shows traces of various other exposures.

The placenta is important in providing a healthy environment for the fetus and plays a central role in the pathophysiology of preeclampsia (PE). Fetal and placental developments are influenced by epigenetic programming. There is some evidence that PE is controlled to an altered circadian homeostasis. In a nested case-control study embedded in the Rotterdam Periconceptional Cohort, we obtained placental tissue, umbilical cord leukocytes (UCL), and human umbilical venous endothelial cells of 13 early-onset PE, 16 late-onset PE and 83 controls comprising 36 uncomplicated and 47 complicated pregnancies, i.e. 27 fetal growth restricted and 20 spontaneous preterm birth. To investigate the associations between PE and the epigenetics of circadian clock and clock-controlled genes in placental and newborn tissues, genome-wide DNA methylation analysis was performed using the Illumina HumanMethylation450K BeadChip and a candidate-gene approach using ANCOVA was applied on 939 CpGs of 39 circadian clock and clock-controlled genes. DNA methylation significantly differed in early-onset PE compared with spontaneous preterm birth at 6 CpGs in placental tissue (3.73 E-5 ≤ p ≤ 0.016) and at 21 CpGs in UCL (1.09 E-5 ≤ p ≤ 0.024). In early-onset PE compared with fetal growth restriction 2 CpGs in placental tissue (p < 0.05) and 8 CpGs in uncomplicated controls (4.78 E-5 ≤ p ≤ 0.049) were significantly different. Moreover, significantly different DNA methylation in early-onset PE compared with uncomplicated controls was shown at 6 CpGs in placental tissue (1.36 E-4 ≤ p ≤ 0.045) and 11 CpGs in uncomplicated controls (2.52 E-6 ≤ p ≤ 0.009). No significant associations were shown with late-onset PE between study groups or tissues. The most differentially methylated CpGs showed hypomethylation in placental tissue and hypermethylation in uncomplicated controls. In conclusion, DNA methylation of circadian clock and clock-controlled genes demonstrated most differences in UCL of early-onset PE compared with spontaneous preterm birth. Implications of the tissue-specific variations in epigenetic programming for circadian performance and long-term health need further investigation.

The development of these guidelines is mandated by the American Association of Clinical Endocrinologists (AACE) Board of Directors and American College of Endocrinology (ACE) Board of Trustees and adheres with published AACE protocols for the standardized production of clinical practice guidelines (CPGs). Recommendations are based on diligent reviews of the clinical evidence with transparent incorporation of subjective factors, according to established AACE/ACE guidelines for guidelines protocols. The Executive Summary of this document contains 87 recommendations of which 45 are Grade A (51.7%), 18 are Grade B (20.7%), 15 are Grade C (17.2%), and 9 (10.3%) are Grade D. These detailed, evidence-based recommendations allow for nuance-based clinical decision-making that addresses multiple aspects of real-world medical care. The evidence base presented in the subsequent Appendix provides relevant supporting information for Executive Summary Recommendations. This update contains 695 citations of which 203 (29.2 %) are EL 1 (strong), 137 (19.7%) are EL 2 (intermediate), 119 (17.1%) are EL 3 (weak), and 236 (34.0%) are EL 4 (no clinical evidence). This CPG is a practical tool that endocrinologists, other health care professionals, health-related organizations, and regulatory bodies can use to reduce the risks and consequences of dyslipidemia. It provides guidance on screening, risk assessment, and treatment recommendations for a range of individuals with various lipid disorders. The recommendations emphasize the importance of treating low-density lipoprotein cholesterol (LDL-C) in some individuals to lower goals than previously endorsed and support the measurement of coronary artery calcium scores and inflammatory markers to help stratify risk. Special consideration is given to individuals with diabetes, familial hypercholesterolemia, women, and youth with dyslipidemia.

Clinical practice guidelines on the management of neck pain make recommendations to help practitioners optimize patient care. By examining the practice patterns of practitioners, adherence to CPGs or lack thereof, is demonstrated. Understanding utilization of various treatments by practitioners and comparing these patterns to that of recommended guidelines is important to identify gaps for knowledge translation and improve treatment regimens. To describe the utilization of interventions in patients with neck pain by clinicians. A cross-sectional international survey was conducted from February 2012 to March 2013 to determine physical medicine, complementary and alternative medicine utilization amongst 360 clinicians treating patients with neck pain. The survey was international (19 countries) with Canada having the largest response (38%). Results were analyzed by usage amongst physical therapists (38%) and chiropractors (31%) as they were the predominant respondents. Within these professions, respondents were male (41-66%) working in private practice (69-95%). Exercise and manual therapies were consistently (98-99%) used by both professions but tests of subgroup differences determined that physical therapists used exercise, orthoses and 'other' interventions more, while chiropractors used phototherapeutics more. However, phototherapeutics (65%), Orthoses/supportive devices (57%), mechanical traction (55%) and sonic therapies (54%) were not used by the majority of respondents. Thermal applications (73%) and acupuncture (46%) were the modalities used most commonly. Analysis of differences across the subtypes of neck pain indicated that respondents utilize treatments more often for chronic neck pain and whiplash conditions, followed by radiculopathy, acute neck pain and whiplash conditions, and facet joint dysfunction by diagnostic block. The higher rates of usage of some interventions were consistent with supporting evidence (e.g. manual therapy). However, there was moderate usage of a number of interventions that have limited support or conflicting evidence (e.g. ergonomics). This survey indicates that exercise and manual therapy are core treatments provided by chiropractors and physical therapists. Future research should address gaps in evidence associated with variable practice patterns and knowledge translation to reduce usage of some interventions that have been shown to be ineffective.

Background DNA methylation leaves a long-term signature of smoking exposure and is one potential mechanism by which tobacco exposure predisposes to adverse health outcomes, such as cancers, osteoporosis, lung, and cardiovascular disorders. Methods and Results To comprehensively determine the association between cigarette smoking and DNA methylation, we conducted a meta-analysis of genome-wide DNA methylation assessed using the Illumina BeadChip 450K array on 15,907 blood derived DNA samples from participants in 16 cohorts (including 2,433 current, 6,518 former, and 6,956 never smokers). Comparing current versus never smokers, 2,623 CpG sites (CpGs), annotated to 1,405 genes, were statistically significantly differentially methylated at Bonferroni threshold of p<1×10−7 (18,760 CpGs at False Discovery Rate (FDR)<0.05). Genes annotated to these CpGs were enriched for associations with several smoking-related traits in genome-wide studies including pulmonary function, cancers, inflammatory diseases and heart disease. Comparing former versus never smokers, 185 of the CpGs that differed between current and never smokers were significant p<1×10−7 (2,623 CpGs at FDR<0.05), indicating a pattern of persistent altered methylation, with attenuation, after smoking cessation. Transcriptomic integration identified effects on gene expression at many differentially methylated CpGs. Conclusions Cigarette smoking has a broad impact on genome-wide methylation that, at many loci, persists many years after smoking cessation. Many of the differentially methylated genes were novel genes with respect to biologic effects of smoking, and might represent therapeutic targets for prevention or treatment of tobacco-related diseases. Methylation at these sites could also serve as sensitive and stable biomarkers of lifetime exposure to tobacco smoke. PMID:27651444

Transcriptomic integration identified effects on gene expression at many differentially methylated CpGs. Cigarette smoking has a broad impact on genome-wide methylation that, at many loci, persists many years after smoking cessation. Many of the differentially methylated genes were novel genes with respect to biological effects of smoking and might represent therapeutic targets for prevention or treatment of tobacco-related diseases. Methylation at these sites could also serve as sensitive and stable biomarkers of lifetime exposure to tobacco smoke. © 2016 American Heart Association, Inc.

DNA methylation is an important epigenetic modification involved in many biological processes and diseases. Many studies have mapped DNA methylation changes associated with embryogenesis, cell differentiation, and cancer at a genome-wide scale. Our understanding of genome-wide DNA methylation changes in a developmental or disease-related context has been steadily growing. However, the investigation of which CpGs are variably methylated in different normal cell or tissue types is still limited. Here, we present an in-depth analysis of 54 single-CpG-resolution DNA methylomes of normal human cell types by integrating high-throughput sequencing-based methylation data. We found that the ratio of methylated to unmethylated CpGs is relatively constant regardless of cell type. However, which CpGs made up the unmethylated complement was cell-type specific. We categorized the 26,000,000 human autosomal CpGs based on their methylation levels across multiple cell types to identify variably methylated CpGs and found that 22.6% exhibited variable DNA methylation. These variably methylated CpGs formed 660,000 variably methylated regions (VMRs), encompassing 11% of the genome. By integrating a multitude of genomic data, we found that VMRs enrich for histone modifications indicative of enhancers, suggesting their role as regulatory elements marking cell type specificity. VMRs enriched for transcription factor binding sites in a tissue-dependent manner. Importantly, they enriched for GWAS variants, suggesting that VMRs could potentially be implicated in disease and complex traits. Taken together, our results highlight the link between CpG methylation variation, genetic variation, and disease risk for many human cell types. Copyright © 2016 Gu et al.

Background: Although bronchiolitis poses a significant health problem in low- and middle-income countries (LMICs), to the best of our knowledge, to date it has not been determined whether evidence-based bronchiolitis clinical practice guidelines (CPGs) complemented by standardized educational strategies reduce the use of unnecessary diagnostic tests and medications and improve clinically important outcomes in LMICs. Methods: In an uncontrolled before and after study, we assessed the impact of the implementation of an evidence-based bronchiolitis CPG on physician behavior and the care of infants with bronchiolitis by comparing pre-guideline (March to August 2014) and post-guideline (March to August 2015) use of diagnostic tests and medications through an electronic medical record review in a children’s hospital in Bogota, Colombia. We also sought to assess the impact of the implementation of the CPG on clinically important outcomes such as lengths of stay, hospital admissions, intensive care admissions, and hospital readmissions. Results: Data from 662 cases of bronchiolitis (pre-guideline period) were compared with the data from 703 cases (post-guideline period). On comparing the pre- and post-guideline periods, it was seen that there was a significant increase in the proportion of patients with an appropriate diagnosis and treatment of bronchiolitis (36.4% versus 44.5%, p = 0.003), and there were statistically significant decreases in the use of a hemogram (33.2% versus 26.6%, p=0.010), procalcitonin (3.9% versus 1.6%, p=0.018), nebulized beta-2 agonists (45.6% versus 3.4%, p < 0.001), nebulized anticholinergics (3.3% versus 1.4%, p= 0.029), and nebulized epinephrine (16.2% versus 7.8%, p < 0.001). Likewise, a significant increase in the use of nebulized hypertonic saline was seen (79.6% versus 91.7%, p < 0.001). However, implementation of the CPG for bronchiolitis was not associated with significant changes in clinically important outcomes. Conclusions: The development and implementation of a good quality bronchiolitis CPG is associated with a significant increase in the proportion of cases with an appropriate diagnosis and treatment of the disease in the context of a university-based hospital located in the capital of an LMIC. However, we could not demonstrate an improvement in clinically important outcomes such as any of the bronchiolitis severity parameters. PMID:27492738

Rhythm generation, coordination, and initiation in the vocal pathways of male African clawed frogs

Central pattern generators (CPGs) in the brain stem are considered to underlie vocalizations in many vertebrate species, but the detailed mechanisms underlying how motor rhythms are generated, coordinated, and initiated remain unclear. We addressed these issues using isolated brain preparations of Xenopus laevis from which fictive vocalizations can be elicited. Advertisement calls of male X. laevis that consist of fast and slow trills are generated by vocal CPGs contained in the brain stem. Brain stem central vocal pathways consist of a premotor nucleus [dorsal tegmental area of medulla (DTAM)] and a laryngeal motor nucleus [a homologue of nucleus ambiguus (n.IX-X)] with extensive reciprocal connections between the nuclei. In addition, DTAM receives descending inputs from the extended amygdala. We found that unilateral transection of the projections between DTAM and n.IX-X eliminated premotor fictive fast trill patterns but did not affect fictive slow trills, suggesting that the fast and slow trill CPGs are distinct; the slow trill CPG is contained in n.IX-X, and the fast trill CPG spans DTAM and n.IX-X. Midline transections that eliminated the anterior, posterior, or both commissures caused no change in the temporal structure of fictive calls, but bilateral synchrony was lost, indicating that the vocal CPGs are contained in the lateral halves of the brain stem and that the commissures synchronize the two oscillators. Furthermore, the elimination of the inputs from extended amygdala to DTAM, in addition to the anterior commissure, resulted in autonomous initiation of fictive fast but not slow trills by each hemibrain stem, indicating that the extended amygdala provides a bilateral signal to initiate fast trills. NEW & NOTEWORTHY Central pattern generators (CPGs) are considered to underlie vocalizations in many vertebrate species, but the detailed mechanisms underlying their functions remain unclear. We addressed this question using an isolated brain preparation of African clawed frogs. We discovered that two vocal phases are mediated by anatomically distinct CPGs, that there are a pair of CPGs contained in the left and right half of the brain stem, and that mechanisms underlying initiation of the two vocal phases are distinct.

The prevalence of eczema is increasing in industrialized nations. Limited evidence has shown the association of DNA methylation (DNA-M) with eczema. We explored this association at the epigenome-scale to better understand the role of DNA-M. Data from the first generation (F1) of the Isle of Wight (IoW) birth cohort participants and the second generation (F2) were examined in our study. Epigenome-scale DNA methylation of F1 at age 18 years and F2 in cord blood was measured using the Illumina Infinium HumanMethylation450 Beadchip. A total of 307,357 cytosine-phosphate-guanine sites (CpGs) in the F1 generation were screened via recursive random forest (RF) for their potential association with eczema at age 18. Functional enrichment and pathway analysis of resulting genes were carried out using DAVID gene functional classification tool. Log-linear models were performed in F1 to corroborate the identified CpGs. Findings in F1 were further replicated in F2. The recursive RF yielded 140 CpGs, 88 of which showed statistically significant associations with eczema at age 18, corroborated by log-linear models after controlling for false discovery rate (FDR) of 0.05. These CpGs were enriched among many biological pathways, including pathways related to creating transcriptional variety and pathways mechanistically linked to eczema such as cadherins, cell adhesion, gap junctions, tight junctions, melanogenesis, and apoptosis. In the F2 generation, about half of the 83 CpGs identified in F1 showed the same direction of association with eczema risk as in F1, of which two CpGs were significantly associated with eczema risk, cg04850479 of the PROZ gene (risk ratio (RR) = 15.1 in F1, 95 % confidence interval (CI) 1.71, 79.5; RR = 6.82 in F2, 95 % CI 1.52, 30.62) and cg01427769 of the NEU1 gene (RR = 0.13 in F1, 95 % CI 0.03, 0.46; RR = 0.09 in F2, 95 % CI 0.03, 0.36). Via epigenome-scaled analyses using recursive RF followed by log-linear models, we identified 88 CpGs associated with eczema in F1, of which 41 were replicated in F2. Several identified CpGs are located within genes in biological pathways relating to skin barrier integrity, which is central to the pathogenesis of eczema. Novel genes associated with eczema risk were identified (e.g., the PROZ and NEU1 genes).

Central pattern generators for social vocalization: Androgen-dependent neurophysiological mechanisms

PubMed Central

Bass, Andrew H.; Remage-Healey, Luke

2008-01-01

Historically, most studies of vertebrate central pattern generators (CPGs) have focused on mechanisms for locomotion and respiration. Here, we highlight new results for ectothermic vertebrates, namely teleost fish and amphibians, showing how androgenic steroids can influence the temporal patterning of CPGs for social vocalization. Investigations of vocalizing teleosts show how androgens can rapidly (within minutes) modulate the neurophysiological output of the vocal CPG (fictive vocalizations that mimic the temporal properties of natural vocalizations) inclusive of their divergent actions between species, as well as intraspecific differences between male reproductive morphs. Studies of anuran amphibians (frogs) demonstrate that long-term steroid treatments (wks) can masculinize the fictive vocalizations of females, inclusive of its sensitivity to rapid modulation by serotonin. Given the conserved organization of vocal control systems across vertebrate groups, the vocal CPGs of fish and amphibians provide tractable models for identifying androgen-dependent events that are fundamental to the mechanisms of vocal motor patterning. These basic mechanisms can also inform our understanding of the more complex CPGs for vocalization, and social behaviors in general, that have evolved among birds and mammals. PMID:18262186

Methylation-based non-invasive prenatal testing of fetal aneuploidies is an alternative method that could possibly improve fetal aneuploidy diagnosis, especially for trisomy 13(T13) and trisomy 18(T18). Our aim was to study the methylation landscape in placenta DNA from trisomy 13, 18 and 21 pregnancies in an attempt to find trisomy-specific methylation differences better suited for non-invasive prenatal diagnosis. We have conducted high-resolution methylation specific bead chip microarray analyses assessing more than 450,000 CpGs analyzing placentas from 12 T21 pregnancies, 12 T18 pregnancies and 6 T13 pregnancies. We have compared the methylation landscape of the trisomic placentas to the methylation landscape from normal placental DNA and to maternal blood cell DNA. Comparing trisomic placentas to normal placentas we identified 217 and 219 differentially methylated CpGs for CVS T18 and CVS T13, respectively (delta β>0.2, FDR<0.05), but only three differentially methylated CpGs for T21. However, the methylation differences was only modest (delta β<0.4), making them less suitable as diagnostic markers. Gene ontology enrichment analysis revealed that the gene set connected to theT18 differentially methylated CpGs was highly enriched for GO terms related to"DNA binding" and "transcription factor binding" coupled to the RNA polymerase II transcription. In the gene set connected to the T13 differentially methylated CpGs we found no significant enrichments.

Purpose Early-stage hepatocellular carcinoma (E-HCC) is being diagnosed increasingly, and in one half of diagnosed patients, recurrence will develop. Thus, it is urgent to identify recurrence-related markers. We investigated the effectiveness of CpG methylation in predicting recurrence for patients with E-HCCs. Patients and Methods In total, 576 patients with E-HCC from four independent centers were sorted by three phases. In the discovery phase, 66 tumor samples were analyzed using the Illumina Methylation 450k Beadchip. Two algorithms, Least Absolute Shrinkage and Selector Operation and Support Vector Machine-Recursive Feature Elimination, were used to select significant CpGs. In the training phase, penalized Cox regression was used to further narrow CpGs into 140 samples. In the validation phase, candidate CpGs were validated using an internal cohort (n = 141) and two external cohorts (n = 191 and n =104). Results After combining the 46 CpGs selected by the Least Absolute Shrinkage and Selector Operation and the Support Vector Machine-Recursive Feature Elimination algorithms, three CpGs corresponding to SCAN domain containing 3, Src homology 3-domain growth factor receptor-bound 2-like interacting protein 1, and peptidase inhibitor 3 were highlighted as candidate predictors in the training phase. On the basis of the three CpGs, a methylation signature for E-HCC (MSEH) was developed to classify patients into high- and low-risk recurrence groups in the training cohort ( P < .001). The performance of MSEH was validated in the internal cohort ( P < .001) and in the two external cohorts ( P < .001; P = .002). Furthermore, a nomogram comprising MSEH, tumor differentiation, cirrhosis, hepatitis B virus surface antigen, and antivirus therapy was generated to predict the 5-year recurrence-free survival in the training cohort, and it performed well in the three validation cohorts (concordance index: 0.725, 0.697, and 0.693, respectively). Conclusion MSEH, a three-CpG-based signature, is useful in predicting recurrence for patients with E-HCC.

Emergent central pattern generator behavior in gap-junction-coupled Hodgkin-Huxley style neuron model.

Horn, Kyle G; Memelli, Heraldo; Solomon, Irene C

2012-01-01

Most models of central pattern generators (CPGs) involve two distinct nuclei mutually inhibiting one another via synapses. Here, we present a single-nucleus model of biologically realistic Hodgkin-Huxley neurons with random gap junction coupling. Despite no explicit division of neurons into two groups, we observe a spontaneous division of neurons into two distinct firing groups. In addition, we also demonstrate this phenomenon in a simplified version of the model, highlighting the importance of afterhyperpolarization currents (I(AHP)) to CPGs utilizing gap junction coupling. The properties of these CPGs also appear sensitive to gap junction conductance, probability of gap junction coupling between cells, topology of gap junction coupling, and, to a lesser extent, input current into our simulated nucleus.

Development of a computer-interpretable clinical guideline model for decision support in the differential diagnosis of hyponatremia.

Hyponatremia is the most common type of electrolyte imbalance, occurring when serum sodium is below threshold levels, typically 135mmol/L. Electrolyte balance has been identified as one of the most challenging subjects for medical students, but also as one of the most relevant areas to learn about according to physicians and researchers. We present a computer-interpretable guideline (CIG) model that will be used for medical training to learn how to improve the diagnosis of hyponatremia applying an expert consensus document (ECDs). We used the PROForma set of tools to develop the model, using an iterative process involving two knowledge engineers (a computer science Ph.D. and a preventive medicine specialist) and two expert endocrinologists. We also carried out an initial validation of the model and a qualitative post-analysis from the results of a retrospective study (N=65 patients), comparing the consensus diagnosis of two experts with the output of the tool. The model includes over two-hundred "for", "against" and "neutral" arguments that are selectively triggered depending on the input value of more than forty patient-state variables. We share the methodology followed for the development process and the initial validation results, that achieved a high ratio of 61/65 agreements with the consensus diagnosis, having a kappa value of K=0.86 for overall agreement and K=0.80 for first-ranked agreement. Hospital care professionals involved in the project showed high expectations of using this tool for training, but the process to follow for a successful diagnosis and application is not trivial, as reported in this manuscript. Secondary benefits of using these tools are associated to improving research knowledge and existing clinical practice guidelines (CPGs) or ECDs. Beyond point-of-care clinical decision support, knowledge-based decision support systems are very attractive as a training tool, to help selected professionals to better understand difficult diseases that are underdiagnosed and/or incorrectly managed.

Primary care management of osteoarthritis (OA) is variable and often inconsistent with clinical practice guidelines (CPGs). This study aimed to identify and synthesize available qualitative evidence on primary care clinicians' views on providing recommended management of OA. Eligibility criteria included full reports published in peer-reviewed journals, with data collected directly from primary care clinicians using qualitative methods for collection and analysis. Five electronic databases (MEDLINE, Cochrane Central Register, EMBASE, CINAHL and PsychInfo) were searched to August 2016. Two independent reviewers identified eligible reports, conducted critical appraisal (based on Critical Appraisal Skills Programme (CASP) criteria), and extracted data. Three reviewers independently, then collaboratively, synthesized and interpreted data through an inductive and iterative process to derive new themes. The Confidence in Evidence from Reviews of Qualitative research (CERQual) approach was used to determine a confidence profile for each finding. Eight studies involving approximately 83 general practitioners (GPs), 24 practice nurses, 12 pharmacists and 10 physical therapists, from Australia, France, United Kingdom, Germany and Mexico were included. Four barriers were identified as themes 1) OA is not that serious, 2) Clinicians are, or perceive they are, under-prepared, 3) Personal beliefs at odds with providing recommended practice, and 4) Dissonant patient expectations. No themes were enablers. Confidence ratings were moderate or low. Synthesising available data revealed barriers that collectively point towards a need to address clinician knowledge gaps, and enhance clinician communication and behaviour change skills to facilitate patient adherence, enable effective conversations and manage dissonant patient expectations.

Epigenetic modifications, including DNA methylation, represent a potential mechanism for environmental impacts on human disease. Maternal smoking in pregnancy remains an important public health problem that impacts child health in a myriad of ways and has potential lifelong consequences. The mechanisms are largely unknown, but epigenetics most likely plays a role. We formed the Pregnancy And Childhood Epigenetics (PACE) consortium and meta-analyzed, across 13 cohorts (n = 6,685), the association between maternal smoking in pregnancy and newborn blood DNA methylation at over 450,000 CpG sites (CpGs) by using the Illumina 450K BeadChip. Over 6,000 CpGs were differentially methylated in relation to maternal smoking at genome-wide statistical significance (false discovery rate, 5%), including 2,965 CpGs corresponding to 2,017 genes not previously related to smoking and methylation in either newborns or adults. Several genes are relevant to diseases that can be caused by maternal smoking (e.g., orofacial clefts and asthma) or adult smoking (e.g., certain cancers). A number of differentially methylated CpGs were associated with gene expression. We observed enrichment in pathways and processes critical to development. In older children (5 cohorts, n = 3,187), 100% of CpGs gave at least nominal levels of significance, far more than expected by chance (p value < 2.2 × 10−16). Results were robust to different normalization methods used across studies and cell type adjustment. In this large scale meta-analysis of methylation data, we identified numerous loci involved in response to maternal smoking in pregnancy with persistence into later childhood and provide insights into mechanisms underlying effects of this important exposure.

Coordination polymer gels with important environmental and biological applications.

PubMed

Jung, Jong Hwa; Lee, Ji Ha; Silverman, Julian R; John, George

2013-02-07

Coordination Polymer Gels (CPGs) constitute a subset of solid-like metal ion and bridging organic ligand structures (similar to metal-organic frameworks) that form multi-dimensional networks through a trapped solvent as a result of non-covalent interactions. While physical properties of these gels are similar to conventional high molecular weight organic polymer gels, coordination polymer gel systems are often fully reversible and can be assembled and disassembled in the presence of additional energy (heat, sonication, shaking) to give a solution of solvated gelators. Compared to gels resulting from purely organic self-assembled low molecular weight gelators, metal ions incorporated into the fibrilar networks spanning the bulk solvent can impart CPGs with added functionalities. The solid/liquid nature of the gels allows for species to migrate through the gel system and interact with metals, ligands, and the solvent. Chemosensing, catalysis, fluorescence, and drug-delivery applications are some of the many potential uses for these dynamic systems, taking advantage of the metal ion's coordination, the organic polydentate ligand's orientation and functionality, or a combination of these properties. By fine tuning these systems through metal ion and ligand selection and by directing self-assembly with external stimuli the rational synthesis of practical systems can be envisaged.

DNA methylation is one of the most extensively studied epigenetic marks in humans. Yet, it is largely unknown what causes variation in DNA methylation between individuals. The comparison of DNA methylation profiles of monozygotic (MZ) twins offers a unique experimental design to examine the extent to which such variation is related to individual-specific environmental influences and stochastic events or to familial factors (DNA sequence and shared environment). We measured genome-wide DNA methylation in buccal samples from ten MZ pairs (age 8–19) using the Illumina 450k array and examined twin correlations for methylation level at 420,921 CpGs after QC. After selecting CpGs showing the most variation in the methylation level between subjects, the mean genome-wide correlation (rho) was 0.54. The correlation was higher, on average, for CpGs within CpG islands (CGIs), compared to CGI shores, shelves and non-CGI regions, particularly at hypomethylated CpGs. This finding suggests that individual-specific environmental and stochastic influences account for more variation in DNA methylation in CpG-poor regions. Our findings also indicate that it is worthwhile to examine heritable and shared environmental influences on buccal DNA methylation in larger studies that also include dizygotic twins. PMID:24802513

The problem of tuning nonlinear dynamical systems parameters, such that the attained results are considered good ones, is a relevant one. This article describes the development of a gait optimization system that allows a fast but stable robot quadruped crawl gait. We combine bio-inspired Central Patterns Generators (CPGs) and Genetic Algorithms (GA). CPGs are modelled as autonomous differential equations, that generate the necessar y limb movement to perform the required walking gait. The GA finds parameterizations of the CPGs parameters which attain good gaits in terms of speed, vibration and stability. Moreover, two constraint handling techniques based on tournament selection and repairing mechanism are embedded in the GA to solve the proposed constrained optimization problem and make the search more efficient. The experimental results, performed on a simulated Aibo robot, demonstrate that our approach allows low vibration with a high velocity and wide stability margin for a quadruped slow crawl gait.

This paper describes the generation of adaptive gait patterns using new Central Pattern Generators (CPGs) including motor dynamic models for a quadruped robot under various environment. The CPGs act as the flexible oscillators of the joints and make the desired angle of the joints. The CPGs are mutually connected each other, and the sets of their coupling parameters are adjusted by genetic algorithm so that the quadruped robot can realize the stable and adequate gait patterns. As a result of generation, the suitable CPG networks for not only a walking straight gait pattern but also rotation gait patterns are obtained. Experimental results demonstrate that the proposed CPG networks are effective to automatically adjust the adaptive gait patterns for the tested quadruped robot under various environment. Furthermore, the target tracking control based on image processing is achieved by combining the generated gait patterns.

The recent upsurge in research on coordination polymer gels (CPGs) stems from their synthetic modularity, nanoscale processability, and versatile functionalities. Here we report self-assembly of an amphiphilic, tripodal low-molecular weight gelator (L) that consists of 4,4',4-[1,3,5-phenyl-tri(methoxy)]-tris-benzene core and 2,2':6',2″-terpyridyl termini, with different metal ions toward the formation of CPGs that show controllable nanomorphologies, tunable emission, and stimuli-responsive behaviors. L can also act as a selective chemosensor for Zn II with very low limit of detection (0.18 ppm) in aqueous medium. Coordination-driven self-assembly of L with Zn II in H 2 O/MeOH solvent mixture results in a coordination polymer hydrogel (ZnL) that exhibits sheet like morphology and charge-transfer emission. On the other hand, coordination of L with Tb III and Eu III in CHCl 3 /tetrahydrofuran solvent mixture results in green- and red-emissive CPGs, respectively, with nanotubular morphology. Moreover, precise stoichiometric control of L/Eu III /Tb III ratio leads to the formation of bimetallic CPGs that show emissions over a broad spectral range, including white-light-emission. We also explore the multistimuli responsive properties of the white-light-emitting CPG by exploiting the dynamics of Ln III -tpy coordination.

Genome-wide association studies have identified loci influencing circulating lipid concentrations in humans; further information on novel contributing genes, pathways, and biology may be gained through studies of epigenetic modifications. To identify epigenetic changes associated with lipid concentrations, we assayed genome-wide DNA methylation at cytosine-guanine dinucleotides (CpGs) in whole blood from 2306 individuals from 2 population-based cohorts, with replication of findings in 2025 additional individuals. We identified 193 CpGs associated with lipid levels in the discovery stage ( P <1.08E-07) and replicated 33 (at Bonferroni-corrected P <0.05), including 25 novel CpGs not previously associated with lipids. Genes at lipid-associated CpGs were enriched in lipid and amino acid metabolism processes. A differentially methylated locus associated with triglycerides and high-density lipoprotein cholesterol (HDL-C; cg27243685; P =8.1E-26 and 9.3E-19) was associated with cis -expression of a reverse cholesterol transporter ( ABCG1; P =7.2E-28) and incident cardiovascular disease events (hazard ratio per SD increment, 1.38; 95% confidence interval, 1.15-1.66; P =0.0007). We found significant cis -methylation quantitative trait loci at 64% of the 193 CpGs with an enrichment of signals from genome-wide association studies of lipid levels ( P TC =0.004, P HDL-C =0.008 and P triglycerides =0.00003) and coronary heart disease ( P =0.0007). For example, genome-wide significant variants associated with low-density lipoprotein cholesterol and coronary heart disease at APOB were cis -methylation quantitative trait loci for a low-density lipoprotein cholesterol-related differentially methylated locus. We report novel associations of DNA methylation with lipid levels, describe epigenetic mechanisms related to previous genome-wide association studies discoveries, and provide evidence implicating epigenetic regulation of reverse cholesterol transport in blood in relation to occurrence of cardiovascular disease events. © 2017 The Authors.

Identification of CNVs through chromosomal microarray (CMA) testing is the first-line investigation in individuals with learning difficulties/congenital abnormalities. Although recognised that CMA testing may identify CNVs encompassing a cancer predisposition gene (CPG), limited information is available on the frequency and nature of such results. We investigated CNV gains and losses affecting 39 CPGs in 3366 pilot index case individuals undergoing CMA testing, and then studied an extended cohort (n=10 454) for CNV losses at 105 CPGs and CNV gains at 9 proto-oncogenes implicated in inherited cancer susceptibility. In the pilot cohort, 31/3366 (0.92%) individuals had a CNV involving one or more of 16/39 CPGs. 30/31 CNVs involved a tumour suppressor gene (TSG), and 1/30 a proto-oncogene (gain of MET ). BMPR1A , TSC2 and TMEM127 were affected in multiple cases. In the second stage analysis, 49/10 454 (0.47%) individuals in the extended cohort had 50 CNVs involving 24/105 CPGs. 43/50 CNVs involved a TSG and 7/50 a proto-oncogene (4 gains, 3 deletions). The most frequently involved genes, FLCN (n=10) and SDHA (n=7), map to the Smith-Magenis and cri-du-chat regions, respectively. Incidental identification of a CNV involving a CPG is not rare and poses challenges for future cancer risk estimation. Prospective data collection from CPG-CNV cohorts ascertained incidentally and through syndromic presentations is required to determine the risks posed by specific CNVs. In particular, ascertainment and investigation of adults with CPG-CNVs and adults with learning disability and cancer, could provide important information to guide clinical management and surveillance. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

The military's approach to traumatic brain injury and post-traumatic stress disorder

Ling, Geoffrey S. F.; Grimes, Jamie; Ecklund, James M.

2014-06-01

Traumatic brain injury (TBI) and Post Traumatic Stress Disorder (PTSD) are common conditions. In Iraq and Afghanistan, explosive blast related TBI became prominent among US service members but the vast majority of TBI was still due to typical causes such as falls and sporting events. PTS has long been a focus of the US military mental health providers. Combat Stress Teams have been integral to forward deployed units since the beginning of the Global War on Terror. Military medical management of disease and injury follows standard of care clinical practice guidelines (CPG) established by civilian counterparts. However, when civilian CPGs do not exist or are not applicable to the military environment, new practice standards are created. Such is the case for mild TBI. In 2009, the VA-DoD CPG for management of mild TBI/concussion was published and a system-wide clinical care program for mild TBI/concussion was introduced. This was the first large scale effort on an entire medical care system to address all severities of TBI in a comprehensive organized way. In 2010, the VA-DoD CPG for management of PTSD was published. Nevertheless, both TBI and PTS are still incompletely understood. Investment in terms of money and effort has been committed by the DoD to their study. The Defense and Veterans Brain Injury Center, National Intrepid Center of Excellence and the Defense Centers of Excellence for Psychological Health and Traumatic Brain Injury are prominent examples of this effort. These are just beginnings, a work in progress ready to leverage advances made scientifically and always striving to provide the very best care to its military beneficiaries.

Appropriateness of tumor marker request: a case of study

Trevisiol, Chiara; Fabricio, Aline S. C.

2017-01-01

Appropriateness is crucial to provide efficient and high-quality health services at affordable costs. Laboratory medicine is a sector of special interest for the investigation of inappropriateness, due to the high rate of technological innovation and its pivotal role in many diseases and clinical settings. Some subjective aspects related to either the patient or physician seem to have a major role on inappropriateness rates. Given the psychological impact of cancer on both patients and physicians, tumor markers represent a case of study for appropriateness. The assessment of inappropriateness of laboratory tests has been focused mainly on ordering patterns. Appropriateness can barely be appraised by matching the requested test with the clinical problem because clinical information on the test requisition form is usually inadequate. Monitoring inappropriateness through individual clinical information may be feasible in inpatient (clinical data are available), while an indirect approach should be used for outpatients. To estimate inappropriateness in outpatients our group developed innovative models based on comparison between the actually ordered and expected requests of tumor marker, calculated according to recommendations of clinical practice guidelines (CPGs) applied to figures of cancer prevalence. The implementation of the model at national scale in Italy led to recognize a very high rate of overordering of tumor markers. The model was further focused by a dedicated algorithm to be adapted to different clinical conditions or organizational settings by applying performance indicators to cohort-wide structured information in electronic health records (EHRs). With this novel approach, we showed that inappropriateness is multifaceted even within the specific category of tumour markers. The model was effective in identifying both over- and underordering. Implementation of evidence based information and monitoring their impact on the clinical practice are parts of the same, multistage, process aimed at the progressive improvement of health care.

Background: Prenatal exposure to maternal cigarette smoking (prenatal smoke exposure) had been associated with altered DNA methylation (DNAm) at birth. Objective: We examined whether such alterations are present from birth through adolescence. Methods: We used the Infinium HumanMethylation450K BeadChip to search across 473,395 CpGs for differential DNAm associated with prenatal smoke exposure during adolescence in a discovery cohort (n = 132) and at birth, during childhood, and during adolescence in a replication cohort (n = 447). Results: In the discovery cohort, we found five CpGs in MYO1G (top-ranking CpG: cg12803068, p = 3.3 × 10–11) and CNTNAP2 (cg25949550, p = 4.0 × 10–9) to be differentially methylated between exposed and nonexposed individuals during adolescence. The CpGs in MYO1G and CNTNAP2 were associated, respectively, with higher and lower DNAm in exposed versus nonexposed adolescents. The same CpGs were differentially methylated at birth, during childhood, and during adolescence in the replication cohort. In both cohorts and at all developmental time points, the differential DNAm was in the same direction and of a similar magnitude, and was not altered appreciably by adjustment for current smoking by the participants or their parents. In addition, four of the five EWAS (epigenome-wide association study)–significant CpGs in the adolescent discovery cohort were also among the top sites of differential methylation in a previous birth cohort, and differential methylation of CpGs in CYP1A1, AHRR, and GFI1 observed in that study was also evident in our discovery cohort. Conclusions: Our findings suggest that modifications of DNAm associated with prenatal maternal smoking may persist in exposed offspring for many years—at least until adolescence.

Background: Smoking increases the risk of many diseases, and it is also linked to blood DNA methylation changes that may be important in disease etiology. Objectives: We sought to identify novel CpG sites associated with cigarette smoking. Methods: We used two epigenome-wide data sets from the Sister Study to identify and confirm CpG sites associated with smoking. One included 908 women with methylation measurements at 27,578 CpG sites using the HumanMethylation27 BeadChip; the other included 200 women with methylation measurements for 473,844 CpG sites using the HumanMethylation450 BeadChip. Significant CpGs from the second data set that were not included in the 27K assay were validated by pyrosequencing in a subset of 476 samples from the first data set. Results: Our study successfully confirmed smoking associations for 9 previously established CpGs and identified 2 potentially novel CpGs: cg26764244 in GNG12 (p = 9.0 × 10–10) and cg22335340 in PTPN6 (p = 2.9 × 10–05). We also found strong evidence of an association between smoking status and cg02657160 in CPOX (p = 7.3 × 10–7), which has not been previously reported. All 12 CpGs were undermethylated in current smokers and showed an increasing percentage of methylation in former and never-smokers. Conclusions: We identified 2 potentially novel smoking related CpG sites, and provided independent replication of 10 previously reported CpGs sites related to smoking, one of which is situated in the gene CPOX. The corresponding enzyme is involved in heme biosynthesis, and smoking is known to increase heme production. Our study extends the evidence base for smoking-related changes in DNA methylation.

CpG Oligodeoxynucleotides Facilitate Delivery of Whole Inactivated H9N2 Influenza Virus via Transepithelial Dendrites of Dendritic Cells in Nasal Mucosa

ABSTRACT The spread of the low-pathogenicity avian H9N2 influenza virus has seriously increased the risk of a new influenza pandemic. Although whole inactivated virus (WIV) vaccine via intranasal pathway is the effective method of blocking virus transmission, the mucosal barrier seems to be a major factor hampering its development. CpG oligodeoxynucleotides, a known adjuvant, can target downstream dendritic cells (DCs) and effectively enhance the mucosal and systemic immune responses. However, the ability of CpGs to assist H9N2 WIV in transepithelial transport remains unknown. Here, in vitro and in vivo, we showed that CpGs provided assistance for H9N2 WIV in recruiting DCs to the nasal epithelial cells (ECs) and forming transepithelial dendrites (TEDs) to capture luminal viruses. CD103+ DCs participated in this process. Chemokine CCL20 from nasal ECs played a key role in driving DC recruitment and TED formation. Virus-loaded DCs quickly migrated into the draining cervical lymph nodes (CLNs) for antigen presentation. In addition, the competence of CpGs was independent of direct epithelial transport via the transcellular or paracellular pathway. Taken together, our data demonstrated that CpGs enhanced the transport of H9N2 WIV via TEDs of nasal DCs, which might be a novel mechanism for optimal adaptive immune responses. IMPORTANCE This paper demonstrates by both an in vivo and an in vitro coculture model that CpG oligodeoxynucleotides, known as an adjuvant generally targeting downstream immune responses, also are crucial for the transport of H9N2 WIV across nasal epithelial cells (ECs) via the uptake of transepithelial dendrites (TEDs). Our results prove for the first time to our knowledge that the immune-potentiating mechanism of CpGs is based on strengthening the transepithelial uptake of H9N2 WIV in nasal mucosa. These findings provide a fresh perspective for further improvement of intranasal influenza vaccines, which are urgently needed in the face of the potential threat of H9N2 influenza. PMID:25810544

Genetic and epigenetic mechanisms may interact and together affect biological processes and disease development. However, most previous studies have investigated genetic and epigenetic mechanisms independently, and studies examining their interactions throughout the human genome are lacking. To identify genetic loci that interact with the epigenome, we performed the first genome-wide DNA methylation quantitative trait locus (mQTL) analysis in human pancreatic islets. We related 574,553 single nucleotide polymorphisms (SNPs) with genome-wide DNA methylation data of 468,787 CpG sites targeting 99% of RefSeq genes in islets from 89 donors. We identified 67,438 SNP-CpG pairs in cis, corresponding to 36,783 SNPs (6.4% of tested SNPs) and 11,735 CpG sites (2.5% of tested CpGs), and 2,562 significant SNP-CpG pairs in trans, corresponding to 1,465 SNPs (0.3% of tested SNPs) and 383 CpG sites (0.08% of tested CpGs), showing significant associations after correction for multiple testing. These include reported diabetes loci, e.g. ADCY5, KCNJ11, HLA-DQA1, INS, PDX1 and GRB10. CpGs of significant cis-mQTLs were overrepresented in the gene body and outside of CpG islands. Follow-up analyses further identified mQTLs associated with gene expression and insulin secretion in human islets. Causal inference test (CIT) identified SNP-CpG pairs where DNA methylation in human islets is the potential mediator of the genetic association with gene expression or insulin secretion. Functional analyses further demonstrated that identified candidate genes (GPX7, GSTT1 and SNX19) directly affect key biological processes such as proliferation and apoptosis in pancreatic β-cells. Finally, we found direct correlations between DNA methylation of 22,773 (4.9%) CpGs with mRNA expression of 4,876 genes, where 90% of the correlations were negative when CpGs were located in the region surrounding transcription start site. Our study demonstrates for the first time how genome-wide genetic and epigenetic variation interacts to influence gene expression, islet function and potential diabetes risk in humans. PMID:25375650

We explored the association between gestational age and cord blood DNA methylation at birth and whether DNA methylation could be effective in predicting gestational age due to limitations with the presently used methods. We used data from the Norwegian Mother and Child Birth Cohort study (MoBa) with Illumina HumanMethylation450 data measured for 1753 newborns in two batches: MoBa 1, n = 1068; and MoBa 2, n = 685. Gestational age was computed using both ultrasound and the last menstrual period. We evaluated associations between DNA methylation and gestational age and developed a statistical model for predicting gestational age using MoBa 1 for training and MoBa 2 for predictions. The prediction model was additionally used to compare ultrasound and last menstrual period-based gestational age predictions. Furthermore, both CpGs and associated genes detected in the training models were compared to those detected in a published prediction model for chronological age. There were 5474 CpGs associated with ultrasound gestational age after adjustment for a set of covariates, including estimated cell type proportions, and Bonferroni-correction for multiple testing. Our model predicted ultrasound gestational age more accurately than it predicted last menstrual period gestational age. DNA methylation at birth appears to be a good predictor of gestational age. Ultrasound gestational age is more strongly associated with methylation than last menstrual period gestational age. The CpGs linked with our gestational age prediction model, and their associated genes, differed substantially from the corresponding CpGs and genes associated with a chronological age prediction model.

Neural mechanism of optimal limb coordination in crustacean swimming

2014-01-01

A fundamental challenge in neuroscience is to understand how biologically salient motor behaviors emerge from properties of the underlying neural circuits. Crayfish, krill, prawns, lobsters, and other long-tailed crustaceans swim by rhythmically moving limbs called swimmerets. Over the entire biological range of animal size and paddling frequency, movements of adjacent swimmerets maintain an approximate quarter-period phase difference with the more posterior limbs leading the cycle. We use a computational fluid dynamics model to show that this frequency-invariant stroke pattern is the most effective and mechanically efficient paddling rhythm across the full range of biologically relevant Reynolds numbers in crustacean swimming. We then show that the organization of the neural circuit underlying swimmeret coordination provides a robust mechanism for generating this stroke pattern. Specifically, the wave-like limb coordination emerges robustly from a combination of the half-center structure of the local central pattern generating circuits (CPGs) that drive the movements of each limb, the asymmetric network topology of the connections between local CPGs, and the phase response properties of the local CPGs, which we measure experimentally. Thus, the crustacean swimmeret system serves as a concrete example in which the architecture of a neural circuit leads to optimal behavior in a robust manner. Furthermore, we consider all possible connection topologies between local CPGs and show that the natural connectivity pattern generates the biomechanically optimal stroke pattern most robustly. Given the high metabolic cost of crustacean swimming, our results suggest that natural selection has pushed the swimmeret neural circuit toward a connection topology that produces optimal behavior.

The contribution of a central pattern generator in a reflex-based neuromuscular model

2014-01-01

Although the concept of central pattern generators (CPGs) controlling locomotion in vertebrates is widely accepted, the presence of specialized CPGs in human locomotion is still a matter of debate. An interesting numerical model developed in the 90s’ demonstrated the important role CPGs could play in human locomotion, both in terms of stability against perturbations, and in terms of speed control. Recently, a reflex-based neuro-musculo-skeletal model has been proposed, showing a level of stability to perturbations similar to the previous model, without any CPG components. Although exhibiting striking similarities with human gaits, the lack of CPG makes the control of speed/step length in the model difficult. In this paper, we hypothesize that a CPG component will offer a meaningful way of controlling the locomotion speed. After introducing the CPG component in the reflex model, and taking advantage of the resulting properties, a simple model for gait modulation is presented. The results highlight the advantages of a CPG as feedforward component in terms of gait modulation. PMID:25018712

Royal Australian and New Zealand College of Psychiatrists clinical practice guidelines for the treatment of schizophrenia and related disorders.

PubMed

2005-01-01

The Royal Australian and New Zealand College of Psychiatrists is co-ordinating the development of clinical practice guidelines (CPGs) in psychiatry, funded under the National Mental Health Strategy (Australia) and the New Zealand Health Funding Authority. This paper presents CPGs for schizophrenia and related disorders. Over the past decade schizophrenia has become more treatable than ever before. A new generation of drug therapies, a renaissance of psychological and psychosocial interventions and a first generation of reform within the specialist mental health system have combined to create an evidence-based climate of realistic optimism. Progressive neuroscientific advances hold out the strong possibility of more definitive biological treatments in the near future. However, this improved potential for better outcomes and quality of life for people with schizophrenia has not been translated into reality in Australia. The efficacy-effectiveness gap is wider for schizophrenia than any other serious medical disorder. Therapeutic nihilism, under-resourcing of services and a stalling of the service reform process, poor morale within specialist mental health services, a lack of broad-based recovery and life support programs, and a climate of tenacious stigma and consequent lack of concern for people with schizophrenia are the contributory causes for this failure to effectively treat. These guidelines therefore tackle only one element in the endeavour to reduce the impact of schizophrenia. They distil the current evidence-base and make recommendations based on the best available knowledge. A comprehensive literature review (1990-2003) was conducted, including all Cochrane schizophrenia reviews and all relevant meta-analyses, and a number of recent international clinical practice guidelines were consulted. A series of drafts were refined by the expert committee and enhanced through a bi-national consultation process. This guideline provides evidence-based recommendations for the management of schizophrenia by treatment type and by phase of illness. The essential features of the guidelines are: (i) Early detection and comprehensive treatment of first episode cases is a priority since the psychosocial and possibly the biological impact of illness can be minimized and outcome improved. An optimistic attitude on the part of health professionals is an essential ingredient from the outset and across all phases of illness. (ii) Comprehensive and sustained intervention should be assured during the initial 3-5 years following diagnosis since course of illness is strongly influenced by what occurs in this 'critical period'. Patients should not have to 'prove chronicity' before they gain consistent access and tenure to specialist mental health services. (iii) Antipsychotic medication is the cornerstone of treatment. These medicines have improved in quality and tolerability, yet should be used cautiously and in a more targeted manner than in the past. The treatment of choice for most patients is now the novel antipsychotic medications because of their superior tolerability and, in particular, the reduced risk of tardive dyskinesia. This is particularly so for the first episode patient where, due to superior tolerability, novel agents are the first, second and third line choice. These novel agents are nevertheless associated with potentially serious medium to long-term side-effects of their own for which patients must be carefully monitored. Conventional antipsychotic medications in low dosage may still have a role in a small proportion of patients, where there has been full remission and good tolerability; however, the indications are shrinking progressively. These principles are now accepted in most developed countries. (vi) Clozapine should be used early in the course, as soon as treatment resistance to at least two antipsychotics has been demonstrated. This usually means incomplete remission of positive symptomatology, but clozapine may also be considered where there are pervasive negative symptoms or significant or persistent suicidal risk is present. (v) Comprehensive psychosocial interventions should be routinely available to all patients and their families, and provided by appropriately trained mental health professionals with time to devote to the task. This includes family interventions, cognitive-behaviour therapy, vocational rehabilitation and other forms of therapy, especially for comorbid conditions, such as substance abuse, depression and anxiety. (vi) The social and cultural environment of people with schizophrenia is an essential arena for intervention. Adequate shelter, financial security, access to meaningful social roles and availability of social support are essential components of recovery and quality of life. (vii) Interventions should be carefully tailored to phase and stage of illness, and to gender and cultural background. (viii) Genuine involvement of consumers and relatives in service development and provision should be standard. (ix) Maintenance of good physical health and prevention and early treatment of serious medical illness has been seriously neglected in the management of schizophrenia, and results in premature death and widespread morbidity. Quality of medical care for people with schizophrenia should be equivalent to the general community standard. (x) General practitioners (GPs)s should always be closely involved in the care of people with schizophrenia. However, this should be truly shared care, and sole care by a GP with minimal or no specialist involvement, while very common, is not regarded as an acceptable standard of care. Optimal treatment of schizophrenia requires a multidisciplinary team approach with a consultant psychiatrist centrally involved.

Endocrine-disrupting chemicals (EDCs), among which is the antiandrogen vinclozolin (VCZ), have been reported to affect the male reproductive system. In this study, VCZ was administered to pregnant mice at the time of embryo sex determination, and its possible effects on the differentially methylated domains (DMDs) of two paternally (H19 and Gtl2) and three maternally (Peg1, Snrpn, and Peg3) imprinted genes were tested in the male offspring. The CpGs methylation status within the five gene DMDs was analyzed in the sperm, tail, liver, and skeletal muscle DNAs by pyrosequencing. In the sperm of controls, the percentages of methylated CpGs were close to the theoretical values of 100 and 0% in paternally or maternally imprinted genes respectively. VCZ decreased the percentages of methylated CpGs of H19 and Gtl2 (respective values 83.1 and 91.5%) and increased those of Peg1, Snrpn, and Peg3 (respective values 11.3, 18.3, and 11.2%). The effects of VCZ were transgenerational, but they disappeared gradually from F1 to F3. The mean sperm concentration of the VCZ-administered female offspring was only 56% of that of the controls in the F1 offspring, and it was back to normal values in the F2 and F3 offspring. In the somatic cells of controls, the percentages of methylated CpGs were close to the theoretical value of 50% and, surprisingly, VCZ altered the methylation of Peg3. We propose that the deleterious effects of VCZ on the male reproductive system are mediated by imprinting defects in the sperm. The reported effects of EDCs on human male spermatogenesis might be mediated by analogous imprinting alterations.

Although it is assumed that epigenetic mechanisms, such as changes in DNA methylation (DNAm), underlie the relationship between adverse intrauterine conditions and adult metabolic health, evidence from human studies remains scarce. Therefore, we evaluated whether DNAm in whole blood mediated the association between prenatal famine exposure and metabolic health in 422 individuals exposed to famine in utero and 463 (sibling) controls. We implemented a two-step analysis, namely, a genome-wide exploration across 342,596 cytosine-phosphate-guanine dinucleotides (CpGs) for potential mediators of the association between prenatal famine exposure and adult body mass index (BMI), serum triglycerides (TG), or glucose concentrations, which was followed by formal mediation analysis. DNAm mediated the association of prenatal famine exposure with adult BMI and TG but not with glucose. DNAm at PIM3 (cg09349128), a gene involved in energy metabolism, mediated 13.4% [95% confidence interval (CI), 5 to 28%] of the association between famine exposure and BMI. DNAm at six CpGs, including TXNIP (cg19693031), influencing β cell function, and ABCG1 (cg07397296), affecting lipid metabolism, together mediated 80% (95% CI, 38.5 to 100%) of the association between famine exposure and TG. Analyses restricted to those exposed to famine during early gestation identified additional CpGs mediating the relationship with TG near PFKFB3 (glycolysis) and METTL8 (adipogenesis). DNAm at the CpGs involved was associated with gene expression in an external data set and correlated with DNAm levels in fat depots in additional postmortem data. Our data are consistent with the hypothesis that epigenetic mechanisms mediate the influence of transient adverse environmental factors in early life on long-term metabolic health. The specific mechanism awaits elucidation. PMID:29399631

Background Aberrant DNA methylation may promote prostate carcinogenesis. We investigated epigenome-wide DNA methylation profiles in prostate cancer (PCa) compared to adjacent benign tissue to identify differentially methylated CpG sites. Methods The study included paired PCa and adjacent benign tissue samples from 20 radical prostatectomy patients. Epigenetic profiling was done using the Infinium HumanMethylation450 BeadChip. Linear models that accounted for the paired study design and False Discovery Rate Q-values were used to evaluate differential CpG methylation. mRNA expression levels of the genes with the most differentially methylated CpG sites were analyzed. Results In total, 2,040 differentially methylated CpG sites were identified in PCa versus adjacent benign tissue (Q-value <0.001), the majority of which were hypermethylated (n = 1,946; 95%). DNA methylation profiles accurately distinguished between PCa and benign tissue samples. Twenty-seven top-ranked hypermethylated CpGs had a mean methylation difference of at least 40% between tissue types, which included 25 CpGs in 17 genes. Furthermore, for ten genes over 50% of promoter region CpGs were hypermethylated in PCa versus benign tissue. The top-ranked differentially methylated genes included three genes that were associated with both promoter hypermethylation and reduced gene expression: SCGB3A1, HIF3A, and AOX1. Analysis of The Cancer Genome Atlas (TCGA) data provided confirmatory evidence for our findings. Conclusions This study of PCa versus adjacent benign tissue showed many differentially methylated CpGs and regions in and outside gene promoter regions, which may potentially be used for the development of future epigenetic-based diagnostic tests or as therapeutic targets.

Realising the Promise of Cancer Predisposition Genes

PubMed Central

Rahman, Nazneen

2016-01-01

Genes in which germline mutations confer high or moderate increased risks of cancer are called cancer predisposition genes (CPG). Over 100 CPGs have been identified providing important scientific insights in many areas, particularly mechanisms of cancer causation. Moreover, clinical utilisation of CPGs has had substantial impact in diagnosis, optimised management and prevention of cancer. The recent transformative advances in DNA sequencing bring the promise of many more CPG discoveries and greater, broader clinical applications. However, there is also considerable potential for incorrect inferences and inappropriate clinical applications. Realising the promise of cancer predisposition genes for science and medicine will thus require careful navigation. PMID:24429628

A generalized locomotion CPG architecture based on oscillatory building blocks.

Yang, Zhijun; França, Felipe M G

2003-07-01

Neural oscillation is one of the most extensively investigated topics of artificial neural networks. Scientific approaches to the functionalities of both natural and artificial intelligences are strongly related to mechanisms underlying oscillatory activities. This paper concerns itself with the assumption of the existence of central pattern generators (CPGs), which are the plausible neural architectures with oscillatory capabilities, and presents a discrete and generalized approach to the functionality of locomotor CPGs of legged animals. Based on scheduling by multiple edge reversal (SMER), a primitive and deterministic distributed algorithm, it is shown how oscillatory building block (OBB) modules can be created and, hence, how OBB-based networks can be formulated as asymmetric Hopfield-like neural networks for the generation of complex coordinated rhythmic patterns observed among pairs of biological motor neurons working during different gait patterns. It is also shown that the resulting Hopfield-like network possesses the property of reproducing the whole spectrum of different gaits intrinsic to the target locomotor CPGs. Although the new approach is not restricted to the understanding of the neurolocomotor system of any particular animal, hexapodal and quadrupedal gait patterns are chosen as illustrations given the wide interest expressed by the ongoing research in the area.

Evolution of central pattern generators and rhythmic behaviours

PubMed Central

Katz, Paul S.

2016-01-01

Comparisons of rhythmic movements and the central pattern generators (CPGs) that control them uncover principles about the evolution of behaviour and neural circuits. Over the course of evolutionary history, gradual evolution of behaviours and their neural circuitry within any lineage of animals has been a predominant occurrence. Small changes in gene regulation can lead to divergence of circuit organization and corresponding changes in behaviour. However, some behavioural divergence has resulted from large-scale rewiring of the neural network. Divergence of CPG circuits has also occurred without a corresponding change in behaviour. When analogous rhythmic behaviours have evolved independently, it has generally been with different neural mechanisms. Repeated evolution of particular rhythmic behaviours has occurred within some lineages due to parallel evolution or latent CPGs. Particular motor pattern generating mechanisms have also evolved independently in separate lineages. The evolution of CPGs and rhythmic behaviours shows that although most behaviours and neural circuits are highly conserved, the nature of the behaviour does not dictate the neural mechanism and that the presence of homologous neural components does not determine the behaviour. This suggests that although behaviour is generated by neural circuits, natural selection can act separately on these two levels of biological organization. PMID:26598733

Efficacy of a strategy for implementing a guideline for the control of cardiovascular risk in a primary healthcare setting: the SIRVA2 study a controlled, blinded community intervention trial randomised by clusters

PubMed Central

2011-01-01

This work describes the methodology used to assess a strategy for implementing clinical practice guidelines (CPG) for cardiovascular risk control in a health area of Madrid. Background The results on clinical practice of introducing CPGs have been little studied in Spain. The strategy used to implement a CPG is known to influence its final use. Strategies based on the involvement of opinion leaders and that are easily executed appear to be among the most successful. Aim The main aim of the present work was to compare the effectiveness of two strategies for implementing a CPG designed to reduce cardiovascular risk in the primary healthcare setting, measured in terms of improvements in the recording of calculated cardiovascular risk or specific risk factors in patients' medical records, the control of cardiovascular risk factors, and the incidence of cardiovascular events. Methods This study involved a controlled, blinded community intervention in which the 21 health centres of the Number 2 Health Area of Madrid were randomly assigned by clusters to be involved in either a proposed CPG implementation strategy to reduce cardiovascular risk, or the normal dissemination strategy. The study subjects were patients ≥ 45 years of age whose health cards showed them to belong to the studied health area. The main variable examined was the proportion of patients whose medical histories included the calculation of their cardiovascular risk or that explicitly mentioned the presence of variables necessary for its calculation. The sample size was calculated for a comparison of proportions with alpha = 0.05 and beta = 0.20, and assuming that the intervention would lead to a 15% increase in the measured variables. Corrections were made for the design effect, assigning a sample size to each cluster proportional to the size of the population served by the corresponding health centre, and assuming losses of 20%. This demanded a final sample size of 620 patients. Data were analysed using summary measures for each cluster, both in making estimates and for hypothesis testing. Analysis of the variables was made on an intention-to-treat basis. Trial Registration ClinicalTrials.gov: NCT01270022 PMID:21504570

ABSTRACT As part of the American Society for Microbiology (ASM) Evidence-Based Laboratory Medicine Practice Guidelines Committee of the Professional Practice Committee, an ad hoc committee was formed in 2014 to assess guidelines published by the committee using an assessment tool, Appraisal of Guidelines for Research Evaluation II (AGREE II). The AGREE II assessment helps reviewers determine whether published guidelines are robust, transparent, and clear in presenting practice recommendations in a standardized manner. Identifying strengths and weaknesses of practice guidelines by ad hoc assessments helps with improving future guidelines through the participation of key stakeholders. This minireview describes the development of the ad hoc committee and results from their review of several ASM best practices guidelines and a non-ASM practice guideline from the Emergency Nurses Association.

Medicinal leeches (Hirudo spp.) swim using a metachronal, front-to-back undulation. The behavior is generated by central pattern generators (CPGs) distributed along the animal’s midbody ganglia and is coordinated by both central and peripheral mechanisms. Here we report that a component of the venom of Conus imperialis, α-conotoxin ImI, known to block nicotinic acetylcholine receptors in other species, disrupts swimming. Leeches injected with the toxin swam in circles with exaggerated dorsoventral bends and reduced forward velocity. Fictive swimming in isolated nerve cords was even more strongly disrupted, indicating that the toxin targets the CPGs and central coordination, while peripheral coordination partially rescues the behavior in intact animals.

Oliveira, Miguel; Santos, Cristina P.; Costa, Lino

2012-09-01

In this paper, a study based on sensitivity analysis is performed for a gait multi-objective optimization system that combines bio-inspired Central Patterns Generators (CPGs) and a multi-objective evolutionary algorithm based on NSGA-II. In this system, CPGs are modeled as autonomous differential equations, that generate the necessary limb movement to perform the required walking gait. In order to optimize the walking gait, a multi-objective problem with three conflicting objectives is formulated: maximization of the velocity, the wide stability margin and the behavioral diversity. The experimental results highlight the effectiveness of this multi-objective approach and the importance of the objectives to find different walking gait solutions for the quadruped robot.

Avoidable costs of physical treatments for chronic back, neck and shoulder pain within the Spanish National Health Service: a cross-sectional study

PubMed Central

2011-01-01

Background Back, neck and shoulder pain are the most common causes of occupational disability. They reduce health-related quality of life and have a significant economic impact. Many different forms of physical treatment are routinely used. The objective of this study was to estimate the cost of physical treatments which, despite the absence of evidence supporting their effectiveness, were used between 2004 and 2007 for chronic and non-specific neck pain (NP), back pain (BP) and shoulder pain (SP), within the Spanish National Health Service in the Canary Islands (SNHSCI). Methods Chronic patients referred from the SNHSCI to private physical therapy centres for NP, BP or SP, between 2004 and 2007, were identified. The cost of providing physical therapies to these patients was estimated. Systematic reviews (SRs) and clinical practice guidelines (CPGs) for NP, BP and SP available in the same period were searched for and rated according to the Oxman and AGREE criteria, respectively. Those rated positively for ≥70% of the criteria, were used to categorise physical therapies as Effective; Ineffective; Inconclusive; and Insufficiently Assessed. The main outcome was the cost of physical therapies included in each of these categories. Results 8,308 chronic cases of NP, 4,693 of BP and 5,035 of SP, were included in this study. Among prescribed treatments, 39.88% were considered Effective (physical exercise and manual therapy with mobilization); 23.06% Ineffective; 13.38% Inconclusive, and 23.66% Insufficiently Assessed. The total cost of treatments was € 5,107,720. Effective therapies accounted for € 2,069,932. Conclusions Sixty percent of the resources allocated by the SNHSCI to fund physical treatment for NP, BP and SP in private practices are spent on forms of treatment proven to be ineffective, or for which there is no evidence of effectiveness.

Neural tube defects (NTDs) are common birth defects of complex etiology. Though family- and population-based studies have confirmed a genetic component, the responsible genes for NTDs are still largely unknown. Based on the hypothesis that folic acid prevents NTDs by stimulating methylation reactions, epigenetic factors, such as DNA methylation, are predicted to be involved in NTDs. Homeobox (HOX) genes play a role in spinal cord development and are tightly regulated in a spatiotemporal and collinear manner, partly by epigenetic modifications. We have quantified DNA methylation for the different HOX genes by subtracting values from a genome-wide methylation analysis using leukocyte DNA from 10 myelomeningocele (MMC) patients and 6 healthy controls. From the 1575 CpGs profiled for the 4 HOX clusters, 26 CpGs were differentially methylated (P-value < 0.05; β-difference > 0.05) between MMC patients and controls. Seventy-seven percent of these CpGs were located in the HOXA and HOXB clusters, with the most profound difference for 3 CpGs within the HOXB7 gene body. A validation case-control study including 83 MMC patients and 30 unrelated healthy controls confirmed a significant association between MMC and HOXB7 hypomethylation (-14.4%; 95% CI: 11.9–16.9%; P-value < 0.0001) independent of the MTHFR 667C>T genotype. Significant HOXB7 hypomethylation was also present in 12 unaffected siblings, each related to a MMC patient, suggestive of an epigenetic change induced by the mother. The inclusion of a neural tube formation model using zebrafish showed that Hoxb7a overexpression but not depletion resulted in deformed body axes with dysmorphic neural tube formation. Our results implicate HOXB7 hypomethylation as risk factor for NTDs and highlight the importance for future genome-wide DNA methylation analyses without preselecting candidate pathways.

Aside from Gleason sum, few factors accurately identify the subset of prostate cancer patients at high risk for metastatic progression. We hypothesized that epigenetic alterations could distinguish prostate tumors with life-threatening potential. Epigenome-wide DNA methylation profiling was performed in surgically resected primary tumor tissues from a population-based (n = 430) and a replication (n = 80) cohort of prostate cancer patients followed prospectively for at least 5 years. Metastasis was confirmed by positive bone scan, MRI, CT, or biopsy, and death certificates confirmed cause of death. AUC, partial AUC (pAUC, 95% specificity), and P value criteria were used to select differentially methylated CpG sites that robustly stratify patients with metastatic-lethal from nonrecurrent tumors, and which were complementary to Gleason sum. Forty-two CpG biomarkers stratified patients with metastatic-lethal versus nonrecurrent prostate cancer in the discovery cohort, and eight of these CpGs replicated in the validation cohort based on a significant (P < 0.05) AUC (range, 0.66-0.75) or pAUC (range, 0.007-0.009). The biomarkers that improved discrimination of patients with metastatic-lethal prostate cancer include CpGs in five genes (ALKBH5, ATP11A, FHAD1, KLHL8, and PI15) and three intergenic regions. In the validation dataset, the AUC for Gleason sum alone (0.82) significantly increased with the addition of four individual CpGs (range, 0.86-0.89; all P <0.05). Eight differentially methylated CpGs that distinguish patients with metastatic-lethal from nonrecurrent tumors were validated. These novel epigenetic biomarkers warrant further investigation as they may improve prognostic classification of patients with clinically localized prostate cancer and provide new insights on tumor aggressiveness.

Computational Modeling Approach in Probing the Effects of Cytosine Methylation on the Transcription Factor Binding to DNA.

PubMed

Tenayuca, John; Cousins, Kimberley; Yang, Shumei; Zhang, Lubo

2017-01-01

Cytosine methylation at CpG dinucleotides is a chief mechanism in epigenetic modification of gene expression patterns. Previous studies demonstrated that increased CpG methylation of Sp1 sites at -268 and -346 of protein kinase C ε promoter repressed the gene expression. The present study investigated the impact of CpG methylation on the Sp1 binding via molecular modeling and electrophoretic mobility shift assay. Each of the Sp1 sites contain two CpGs. Methylation of either CpG lowered the binding affinity of Sp1, whereas methylation of both CpGs produced a greater decrease in the binding affinity. Computation of van der Waals (VDW) energy of Sp1 in complex with the Sp1 sites demonstrated increased VDW values from one to two sites of CpG methylation. Molecular modeling indicated that single CpG methylation caused underwinding of the DNA fragment, with the phosphate groups at C1, C4 and C5 reoriented from their original positions. Methylation of both CpGs pinched the minor groove and increased the helical twist concomitant with a shallow, hydrophobic major groove. Additionally, double methylation eliminated hydrogen bonds on recognition helix residues located at positions -1 and 1, which were essential for interaction with O6/N7 of G-bases. Bonding from linker residues Arg565, Lys595 and Lys596 were also reduced. Methylation of single or both CpGs significantly affected hydrogen bonding from all three Sp1 DNA binding domains, demonstrating that the consequences of cytosine modification extend beyond the neighboring nucleotides. The results indicate that cytosine methylation causes subtle structural alterations in Sp1 binding sites consequently resulting in inhibition of side chain interactions critical for specific base recognition and reduction of the binding affinity of Sp1.

2016-07-01

The management of thyroid nodules has changed dramatically over the past two decades. In the interim, technological advances including high-resolution ultrasound and molecular testing of thyroid nodules have been introduced. We sought to document current practices in the management thyroid nodules and assess the extent to which technological advances have been incorporated into current practice. We further sought to compare current practice to recommendations made in a recently updated American Thyroid Association (ATA) clinical practice guideline (CPG) and examine differences in thyroid nodule management among international members of U.S.-based endocrine societies. Members of The Endocrine Society, ATA, and American Association of Clinical Endocrinologists were invited to participate in a Web-based survey dealing with testing, treatment preference, and modulating factors in patients with thyroid nodules. A total of 897 respondents participated in the survey, including 661 members of The Endocrine Society, 454 American Association of Clinical Endocrinologists members, and 365 ATA members. Thyroid fine-needle aspiration (FNA) in 2015 is generally performed by endocrinologists (56.6%) and radiologists (31.9%), most frequently using ultrasound guidance (83.3%). Respondents in general have a lower threshold for FNA of thyroid nodules than that recommended in the updated ATA CPG. Management depends on the FNA result, with follicular lesion of undetermined significance/atypia of undetermined significance resulting in molecular testing (38.8% of respondents), repeat FNA cytology (31.5%), or immediate referral for thyroid surgery (24.4%). Nodules showing follicular neoplasm by FNA are referred for thyroid surgery by 61.2% of respondents (46.6 % lobectomy, 14.6 % total thyroidectomy) or molecular testing (29.0 %). Nodules found suspicious but not conclusive for malignancy (Bethesda category V), are referred for thyroid surgery (86.0%) and rarely undergo molecular testing (9.5%). During pregnancy, only 47.6% of respondents would perform FNA in the absence of nodular growth, with most respondents deferring FNA until after pregnancy. Endocrinologists are 64.2% less likely to perform FNA in an octogenarian than a younger patient with a comparable thyroid nodule. Striking international differences were identified in the routine measurement of calcitonin and in the use of molecular testing of thyroid nodules. In summary, our survey of clinical endocrinologists on the management of thyroid nodules documents current practice patterns and demonstrates both concordance and focal discordance with recently updated CPGs. Both international differences and a change in practice patterns during the past two decades are demonstrated.

Are nutrition messages lost in transmission? Assessing the quality and consistency of diabetes guideline recommendations on the delivery of nutrition therapy.

To provide an overview of (1) the consistency of Type 2 Diabetes Clinical Practice Guidelines recommendations on the delivery of nutrition therapy and (2) Clinical Practice Guideline quality. Large international clinical practice guideline repositories, diabetes organisation websites, and electronic databases (Pubmed, Scopus), were searched to identify Clinical Practice Guidelines for adults with type 2 diabetes published 2005 to August 2014. Recommendations on the delivery of nutrition therapy were extracted and inductive content analysis was used to analyse consistency. Two researchers independently assessed guideline quality using the AGREE II tool. Nine topics were identified from the recommendations. Overall the consistency of the recommendations was related to guideline type. Compared with nutrition-specific guidelines, the broad ones had a broader focus and included more patient-focused recommendations. The ten Clinical Practice Guidelines assessed included six broad guidelines and four nutrition specific guidelines. Based on AGREE II analysis, the broad guidelines were higher quality than nutrition-specific ones. Broad Clinical Practice Guidelines were higher quality and included more patient-focused recommendations than nutrition-specific ones. Our findings suggest a need for nutrition-specific guidelines to be modified to include greater patient-focus, or for practitioners delivering nutrition therapy to adopt broad Clinical Practice Guidelines.

The aim of this study is to:a.Highlight the most important guidelines and practices of quality in the pharmaceutical industry.b.Organize such guidelines and practices to create a guide to pave the way for other researchers who would like to dig deeper into these guidelines and practices. A review was conducted of 102 publications; 56 publications were concerned with the pharmaceutical quality directly while 46 publications were concerned with the general quality practices. The content of those sources was analyzed and the following themes were identified:a.Research theme 1: Guidelines of the pharmaceutical quality.b.Research theme 2: General practices recently applied in the pharmaceutical industry. The following guidelines were identified and reviewed: WHO guidelines, FDA guidelines, EU guidelines and ICH guidelines in the research theme I. In research theme II; the following topics were identified and reviewed: quality risk management, quality by design, corrective actions and preventive actions, process capability analysis, Six Sigma, process analytical technology, lean manufacturing, total quality management, ISO series and HACCP. Upon reviewing the previously highlighted guidelines and the practices that are widely applied in the pharmaceutical industry, it was noticed that there is an abundant number of papers and articles that explain the general guidelines and practices but the literature lack those describing application; case studies of the pharmaceutical factories applying those guidelines and significance of those guidelines and practices. It is recommended that the literature would invest more in the area of application and significance of guidelines and practices. New case studies should be done to prove the feasibility of such practices.

At present, several clinical practice guidelines for the treatment of osteoarthritis have been developed by institutes or societies. The ultimate purpose of developing clinical practice guidelines is to formulate the process in the treatment of osteoarthritis effectively. However, the methodologies used in developing clinical practice guidelines may place an influence on the transformation and application of that in treating osteoarthritis. The present study summarized the methodological features of individual clinical practice guideline and presented the tools for quality evaluation of clinical practice guideline.

2009-10-01

In the era of exponential increase in the medical literature, physicians and health policy-makers are relying on well-constructed, evidence-based practice guidelines to help ensure that the care given to patients is based on valid, scientific data. The construction of practice guidelines, however, may not always adhere to accepted research protocol. In this article, the authors detail the steps required to produce effective, evidence-based practice guidelines. The seven essential steps in crafting a practice guideline are presented: (1) defining a topic, (2) selecting a work group, (3) performing a literature review, (4) writing the guideline, (5) peer review, (6) making plans for review and revision, and (7) dissemination. Given the importance of practice guidelines in supporting everyday practice, this article strives to provide a practical guide in the development of this key component of evidence-based medicine.

Objectives The aim of this study is to:a.Highlight the most important guidelines and practices of quality in the pharmaceutical industry.b.Organize such guidelines and practices to create a guide to pave the way for other researchers who would like to dig deeper into these guidelines and practices. Design A review was conducted of 102 publications; 56 publications were concerned with the pharmaceutical quality directly while 46 publications were concerned with the general quality practices. The content of those sources was analyzed and the following themes were identified:a.Research theme 1: Guidelines of the pharmaceutical quality.b.Research theme 2: General practices recently applied in the pharmaceutical industry. Main outcome measures The following guidelines were identified and reviewed: WHO guidelines, FDA guidelines, EU guidelines and ICH guidelines in the research theme I. In research theme II; the following topics were identified and reviewed: quality risk management, quality by design, corrective actions and preventive actions, process capability analysis, Six Sigma, process analytical technology, lean manufacturing, total quality management, ISO series and HACCP. Results Upon reviewing the previously highlighted guidelines and the practices that are widely applied in the pharmaceutical industry, it was noticed that there is an abundant number of papers and articles that explain the general guidelines and practices but the literature lack those describing application; case studies of the pharmaceutical factories applying those guidelines and significance of those guidelines and practices. Conclusions It is recommended that the literature would invest more in the area of application and significance of guidelines and practices. New case studies should be done to prove the feasibility of such practices. PMID:26594110

Clinical practice guidelines are an important result of evidence-based research. However, current clinical practice remains out of step with the rapid pace of research advancements. Often, decades pass before research is translated into clinical practice. The National Comprehensive Cancer Network (NCCN) has created evidence-based clinical guidelines to promote effective clinical practice. Formerly, the NCCN established guidelines to reduce cancer-related infections only for neutropenic patients; however, they have expanded their guidelines beyond neutropenia to prevent and treat cancer-related infections. Implementing scientific evidence into clinical practice is challenging and complex, and healthcare professionals should understand barriers to implementing clinical practice guidelines to ensure successful translation into practice. This article provides a brief review of NCCN guidelines and describes common barriers encountered during implementation. In addition, a conceptual framework is offered to help identify and address potential concerns before and after adoption of guidelines.

We previously showed that vitamin A supplementation in early life impacts white adipose tissue (WAT) biology. We here studied the vitamin's effects on DNA methylation of genes crucial for WAT cell development, determination and metabolism. CpG promoter methylation and mRNA expression of Pparg, Zfp423, Pcna, and Rbp4 was compared in inguinal WAT of 21-day-old rats supplemented during the suckling period with vehicle (controls) or an emulsion of vitamin A as retinyl ester (RE) or β-carotene (BC). The methylation profile of promoters was affected by vitamin A supplementation with pronounced differences between the RE and BC groups. In the RE group, hypermethylation of the Rbp4 (at multiple CpGs) and the Pparg2 (at a specific CpG) promoters and hypomethylation of the Pcna promoter (at multiple CpGs) was observed, together with inverse changes in gene expression levels. In the BC group, hypomethylation of the Rbp4 and hypermethylation of the Pcna promoter at distinct CpGs was observed, with no effects on gene expression. In both supplemention groups, hypomethylation and increased expression was found for Zfp423. Thus, modest vitamin A supplementation in early postnatal life impacts methylation marks in developing WAT. Differential epigenetic effects of RE and BC in early life may affect adipose tissue programming activity. Copyright © 2018 Elsevier Inc. All rights reserved.

Determining coding CpG islands by identifying regions significant for pattern statistics on Markov chains.

Recent experimental and computational work confirms that CpGs can be unmethylated inside coding exons, thereby showing that codons may be subjected to both genomic and epigenomic constraint. It is therefore of interest to identify coding CpG islands (CCGIs) that are regions inside exons enriched for CpGs. The difficulty in identifying such islands is that coding exons exhibit sequence biases determined by codon usage and constraints that must be taken into account. We present a method for finding CCGIs that showcases a novel approach we have developed for identifying regions of interest that are significant (with respect to a Markov chain) for the counts of any pattern. Our method begins with the exact computation of tail probabilities for the number of CpGs in all regions contained in coding exons, and then applies a greedy algorithm for selecting islands from among the regions. We show that the greedy algorithm provably optimizes a biologically motivated criterion for selecting islands while controlling the false discovery rate. We applied this approach to the human genome (hg18) and annotated CpG islands in coding exons. The statistical criterion we apply to evaluating islands reduces the number of false positives in existing annotations, while our approach to defining islands reveals significant numbers of undiscovered CCGIs in coding exons. Many of these appear to be examples of functional epigenetic specialization in coding exons.

The Vitamin D Receptor (VDR) gene encodes a transcription factor which, on activation by vitamin D, modulates diverse biological processes including calcium homeostasis and immune function. Genetic variation involving VDR shows striking differences in allele frequency between populations and has been associated with disease susceptibility including tuberculosis and autoimmunity, although results have often been conflicting. We hypothesized that methylation of VDR may be population specific and that the combination of differential methylation and genetic variation may characterise TB predisposition. We use bisulphite conversion and/or pyrosequencing to analyse the methylation status of 17 CpGs of VDR and to genotype 7 SNPs in the 3′ CpG Island (CGI 1060), including the commonly studied SNPs ApaI (rs7975232) and TaqI (rs731236). We show that for lymphoblastoid cell lines from two ethnically diverse populations (Yoruba from HapMap, n=30 and Caucasians, n=30) together with TB cases (n=32) and controls (n=29) from the Venda population of South Africa there are methylation variable positions (MVPs) in the 3′ end that significantly distinguish ethnicity (9/17 CpGs) and TB status (3/17 CpGs). Moreover methylation status shows complex association with TaqI genotype highlighting the need to consider both genetic and epigenetic variants in genetic studies of VDR association with disease.

Epigenetic factors and consumption of alcohol, which suppresses DNA methylation, may influence the development and progression of epithelial ovarian cancer (EOC). However, there is a lack of understanding whether these factors interact to affect the EOC risk. In this study, we aimed to gain insight into this relationship by identifying leukocyte-derived DNA methylation markers acting as potential mediators of alcohol-associated EOC. We implemented a causal inference test (CIT) and the VanderWeele and Vansteelandt multiple mediator model to examine CpG sites that mediate the association between alcohol consumption and EOC risk. We modified one step of the CIT by adopting a high-dimensional inference procedure. The data were based on 196 cases and 202 age-matched controls from the Mayo Clinic Ovarian Cancer Case-Control Study. Implementation of the CIT test revealed two CpG sites (cg09358725, cg11016563), which represent potential mediators of the relationship between alcohol consumption and EOC case-control status. Implementation of the VanderWeele and Vansteelandt multiple mediator model further revealed that these two CpGs were the key mediators. Decreased methylation at both CpGs was more common in cases who drank alcohol at the time of enrollment vs. those who did not. cg11016563 resides in TRPC6 which has been previously shown to be overexpressed in EOC. These findings suggest two CpGs may serve as novel biomarkers for EOC susceptibility.

With the widespread use of information communication technologies, computerized clinical practice guidelines are developed and considered as effective decision supporting tools in assisting the processes of clinical activities. However, the development of computerized clinical practice guidelines in Taiwan is still at the early stage and acceptance level among major users (physicians) of computerized clinical practice guidelines is not satisfactory. This study aims to investigate critical factors influencing physicians' intention to computerized clinical practice guideline use through an integrative model of activity theory and the technology acceptance model. The survey methodology was employed to collect data from physicians of the investigated hospitals that have implemented computerized clinical practice guidelines. A total of 505 questionnaires were sent out, with 238 completed copies returned, indicating a valid response rate of 47.1 %. The collected data was then analyzed by structural equation modeling technique. The results showed that attitudes toward using computerized clinical practice guidelines (γ = 0.451, p < 0.001), organizational support (γ = 0.285, p < 0.001), perceived usefulness of computerized clinical practice guidelines (γ = 0.219, p < 0.05), and social influence (γ = 0.213, p < 0.05) were critical factors influencing physicians' intention to use computerized clinical practice guidelines, and these factors can explain 68.6 % of the variance in intention to use computerized clinical practice guidelines. This study confirmed that some subject (human) factors, environment (organization) factors, tool (technology) factors mentioned in the activity theory should be carefully considered when introducing computerized clinical practice guidelines. Managers should pay much attention on those identified factors and provide adequate resources and incentives to help the promotion and use of computerized clinical practice guidelines. Through the appropriate use of computerized clinical practice guidelines, the clinical benefits, particularly in improving quality of care and facilitating the clinical processes, will be realized.

Purpose The purpose of the present systematic review was to develop a practice guideline to inform health care providers about screening, assessment, and effective management of cancer-related fatigue (crf) in adults. Methods The internationally endorsed adapte methodology was used to develop a practice guideline for pan-Canadian use. A systematic search of the literature identified a broad range of evidence: clinical practice guidelines, systematic reviews, and other guidance documents on the screening, assessment, and management of crf. The search included medline, embase, cinahl, the Cochrane Library, and other guideline and data sources to December 2009. Results Two clinical practice guidelines were identified for adaptation. Seven guidance documents and four systematic reviews also provided supplementary evidence to inform guideline recommendations. Health professionals across Canada provided expert feedback on the adapted recommendations in the practice guideline and algorithm through a participatory external review process. Conclusions Practice guidelines can facilitate the adoption of evidence-based assessment and interventions for adult cancer patients experiencing fatigue. Development of an algorithm to guide decision-making in practice may also foster the uptake of a guideline into routine care. PMID:23737693

Genome-wide methylation arrays are powerful tools for assessing cell composition of complex mixtures. We compare three approaches to select reference libraries for deconvoluting neutrophil, monocyte, B-lymphocyte, natural killer, and CD4+ and CD8+ T-cell fractions based on blood-derived DNA methylation signatures assayed using the Illumina HumanMethylationEPIC array. The IDOL algorithm identifies a library of 450 CpGs, resulting in an average R 2  = 99.2 across cell types when applied to EPIC methylation data collected on artificial mixtures constructed from the above cell types. Of the 450 CpGs, 69% are unique to EPIC. This library has the potential to reduce unintended technical differences across array platforms.

Consensus statements and clinical practice guidelines are widely available for enhancing the care of cancer patients. Despite subtle differences in their definition and purpose, these terms are often used interchangeably. We systematically assessed the methodological quality of consensus statements and clinical practice guidelines published in three commonly read, geographically diverse, cancer-specific journals. Methods Consensus statements and clinical practice guidelines published between January 2005 and September 2013 in Current Oncology, European Journal of Cancer and Journal of Clinical Oncology were evaluated. Each publication was assessed using the Appraisal of Guidelines for Research and Evaluation II (AGREE II) rigour of development and editorial independence domains. For assessment of transparency of document development, 7 additional items were taken from the Institute of Medicine's standards for practice guidelines and the Journal of Clinical Oncology guidelines for authors of guidance documents. Consensus statements and clinical practice guidelines published between January 2005 and September 2013 in Current Oncology, European Journal of Cancer and Journal of Clinical Oncology were evaluated. Each publication was assessed using the Appraisal of Guidelines for Research and Evaluation II (AGREE II) rigour of development and editorial independence domains. For assessment of transparency of document development, 7 additional items were taken from the Institute of Medicine's standards for practice guidelines and the Journal of Clinical Oncology guidelines for authors of guidance documents. Thirty-four consensus statements and 67 clinical practice guidelines were evaluated. The rigour of development score for consensus statements over the three journals was 32% lower than that of clinical practice guidelines. The editorial independence score was 15% lower for consensus statements than clinical practice guidelines. One journal scored consistently lower than the others over both domains. No journals adhered to all the items related to the transparency of document development. One journal's consensus statements endorsed a product made by the sponsoring pharmaceutical company in 64% of cases. Guidance documents are an essential part of oncology care and should be subjected to a rigorous and validated development process. Consensus statements had lower methodological quality than clinical practice guidelines using AGREE II. At a minimum, journals should ensure that that all consensus statements and clinical practice guidelines adhere to AGREE II criteria. Journals should consider explicitly requiring guidelines to declare pharmaceutical company sponsorship and to identify the sponsor's product to enhance transparency.

2018-04-01

Objective The American Academy of Otolaryngology-Head and Neck Surgery Foundation clinical practice guideline (CPG) proposes recommendations regarding sudden sensorineural hearing loss (SSNHL). SSNHL is managed by primary care, emergency medicine, and otolaryngology providers in the Department of Defense (DoD). However, their adherence to this CPG is unknown. We sought to determine provider compliance and identify areas for improvement. Study Design Case series with chart review. Setting DoD's electronic medical record. Subjects and Methods Patients with SSNHL (N = 204) were treated between March 1, 2012, and September 30, 2015. Time from onset of symptoms to evaluation by primary care, emergency department, audiology, and otolaryngology providers and treatments were analyzed. Results The average interval from onset of symptoms to evaluation by a primary care or emergency department provider was 4.86 days (95% CI, 3.46-6.26). Time from presentation to ear, nose, and throat and audiologic evaluation was 15.26 days (95% CI, 12.34-18.20) and 14.16 days (95% CI, 11.31-17.01), respectively. Diagnostic workup included magnetic resonance imaging (n = 150, 73.5%), computed tomography (n = 28, 13.7%), and laboratory testing (n = 50, 24.5%). Oral steroids were used in 137 (67.2%) patients, with 78.8% treated with the recommended dose. Intratympanic steroids were utilized in 65 (31.9%) patients, with variable dosing. Conclusion The DoD is uniquely positioned to evaluate adherence to CPGs on national and international levels given the robust and standardized electronic medical record. Areas of improvement include timely identification of SSNHL with rapid referral to ear, nose, and throat and audiology providers; minimizing unnecessary imaging, laboratory testing, and medications; and correct dosing of oral and intratympanic steroids.

Neck Pain (NP) is a common musculoskeletal disorder and the literature provides conflicting evidence about its management. To describe the methodology used to conduct an overview of reviews (OvR) and to characterize the distribution and risk of bias profiles across the evidence for all areas of NP management. Standard systematic review (SR) methodology was employed. MEDLINE, CINAHL, EMBASE, ILC, Cochrane CENTRAL, and LILACS were searched from 2000 to March 2012; Narrative and SR and clinical practice guidelines (CPG) evaluating the efficacy of treatment (benefits and harms), diagnosis/classification, prognosis, and outcomes were eligible. For treatment, articles were limited to SRs from 2005 forward. Risk of bias of SR was assessed with the AMSTAR; the AGREE II was used to critically appraise the CPGs. From 2476 articles, 508 were eligible for full text screening. A total of 341 articles were included. Treatment (n=117) had the greatest yield. Other clinical areas had less literature (diagnosis=54, prognosis=16, outcomes=27, harms=16). There were no SR for classification and narrative reviews were problematic for this topic. There was great overlap across different databases within each clinical area except for those for outcome measures. Risk of bias assessment using the AMSTAR of eligible SRs showed a similar trend across different clinical areas. A summary of methods used to review the literature in five clinical areas of NP management have been described. The challenges of selecting and synthesizing eligible articles in an OvR required customized solutions across different areas of clinical focus.

The Sea Slug, Pleurobranchaea californica: A Signpost Species in the Evolution of Complex Nervous Systems and Behavior.

PubMed

Gillette, Rhanor; Brown, Jeffrey W

2015-12-01

How and why did complex brain and behavior evolve? Clues emerge from comparative studies of animals with simpler morphology, nervous system, and behavioral economics. The brains of vertebrates, arthropods, and some annelids have highly derived executive structures and function that control downstream, central pattern generators (CPGs) for locomotion, behavioral choice, and reproduction. For the vertebrates, these structures-cortex, basal ganglia, and hypothalamus-integrate topographically mapped sensory inputs with motivation and memory to transmit complex motor commands to relay stations controlling CPG outputs. Similar computations occur in the central complex and mushroom bodies of the arthropods, and in mammals these interactions structure subjective thought and socially based valuations. The simplest model systems available for comparison are opisthobranch molluscs, which have avoided selective pressure for complex bodies, brain, and behavior through potent chemical defenses. In particular, in the sea-slug Pleurobranchaea californica the functions of vertebrates' olfactory bulb and pallium are performed in the peripheral nervous system (PNS) of the chemotactile oral veil. Functions of hypothalamus and basal ganglia are combined in Pleurobranchaea's feeding motor network. The actions of basal ganglia on downstream locomotor regions and spinal CPGs are analogous to Pleurobranchaea's feeding network actions on CPGs for agonist and antagonist behaviors. The nervous systems of opisthobranch and pulmonate gastropods may conserve or reflect relations of the ancestral urbilaterian. Parallels and contrasts in neuronal circuits for action selection in Pleurobranchaea and vertebrates suggest how a basic set of decision circuitry was built upon in evolving segmentation, articulated skeletons, sociality, and highly invested reproductive strategies. They suggest (1) an origin of olfactory bulb and pallium from head-region PNS; (2) modularization of an ancestral feeding network into discrete but interacting executive modules for incentive comparison and decision (basal ganglia), and homeostatic functions (hypothalamus); (3) modification of a multifunctional premotor network for turns and locomotion, and its downstream targets for mid-brain and hind-brain motor areas and spinal CPGs; (4) condensation of a distributed serotonergic network for arousal into the raphe nuclei, with superimposed control by a peptidergic hypothalamic network mediating appetite and arousal; (5) centralization and condensation of the dopaminergic sensory afferents of the PNS, and/or the disperse dopaminergic elements of central CPGs, into the brain nuclei mediating valuation, reward, and motor arousal; and (6) the urbilaterian possessed the basic circuit relations integrating sensation, internal state, and learning for cost-benefit approach-avoidance decisions. © The Author 2015.

To describe quantitative and qualitative best evidence as sources for practical interventions usable in daily care delivery in order to integrate best evidence into clinical decision-making at local practice settings. To illustrate the development, implementation and evaluation of a pain management nursing care bundle based on a clinical practice guideline via a real-world clinical exemplar. Successful implementation of evidence-based practice requires consistent integration of best evidence into daily clinical decision-making. Best evidence comprises high-quality knowledge summarised in systematic reviews and translated into guidelines. However, consistent integration of guidelines into care delivery remains challenging, partly due to guidelines not being in a usable form for daily practice or relevant for the local context. A position paper with a clinical exemplar of a nurse-led, evidence-based quality improvement project to design, implement and evaluate a pain management care bundle translated from a national nursing guideline. A pragmatic approach to integrating guidelines into daily practice is presented. Best evidence from a national nursing guideline was translated into a pain management care bundle and integrated into daily practice in 15 medical-surgical (med-surg) units of nine hospitals of a large university hospital system in Finland. Translation of best evidence from guidelines into usable form as care bundles adapted to the local setting may increase implementation and uptake of guidelines and improve quality and consistency of care delivery. A pragmatic approach to translating a nursing guideline into a pain management care bundle to incorporate best evidence into daily practice may help achieve more consistent and equitable integration of guidelines into care delivery, and better quality of pain management and patient outcomes. © 2015 John Wiley & Sons Ltd.

The objectives of this study were to: (1) examine differences in the use of dental clinical practice guidelines among Japanese dentists, and (2) identify characteristics associated with the number of guidelines used by participating dentists. We conducted a cross-sectional study consisting of a questionnaire survey in Japan between July 2014 and May 2015. The study queried dentists working in outpatient dental practices who are affiliated with the Dental Practice-Based Research Network Japan (n = 148). They were asked whether they have used each of 15 Japanese dental clinical guidelines. Associations between the number of guidelines used by participants and specific characteristics were analysed via negative binomial regression analysis. The mean number of guidelines used by participating dentists was 2.5 ± 2.9 [standard deviation (SD)]. Rate of use of guidelines showed substantial variation, from 5% to 34% among dentists. The proportion of dentists that used guidelines was the highest among oral medicine specialists, who had the highest proportion for 10 of 15 guidelines. Negative binomial regression analysis identified three factors significantly associated with the number of guidelines used: 'years since graduation from dental school', 'specialty practice' and 'practice busyness'. These results suggest that the use of clinical practice guidelines by Japanese dentists may still be inadequate. Training in the use of the guidelines could be given to dental students as undergraduate education and to young clinicians as continuing education. © 2016 John Wiley & Sons, Ltd.

Computer simulations of neural mechanisms explaining upper and lower limb excitatory neural coupling

PubMed Central

2010-01-01

Background When humans perform rhythmic upper and lower limb locomotor-like movements, there is an excitatory effect of upper limb exertion on lower limb muscle recruitment. To investigate potential neural mechanisms for this behavioral observation, we developed computer simulations modeling interlimb neural pathways among central pattern generators. We hypothesized that enhancement of muscle recruitment from interlimb spinal mechanisms was not sufficient to explain muscle enhancement levels observed in experimental data. Methods We used Matsuoka oscillators for the central pattern generators (CPG) and determined parameters that enhanced amplitudes of rhythmic steady state bursts. Potential mechanisms for output enhancement were excitatory and inhibitory sensory feedback gains, excitatory and inhibitory interlimb coupling gains, and coupling geometry. We first simulated the simplest case, a single CPG, and then expanded the model to have two CPGs and lastly four CPGs. In the two and four CPG models, the lower limb CPGs did not receive supraspinal input such that the only mechanisms available for enhancing output were interlimb coupling gains and sensory feedback gains. Results In a two-CPG model with inhibitory sensory feedback gains, only excitatory gains of ipsilateral flexor-extensor/extensor-flexor coupling produced reciprocal upper-lower limb bursts and enhanced output up to 26%. In a two-CPG model with excitatory sensory feedback gains, excitatory gains of contralateral flexor-flexor/extensor-extensor coupling produced reciprocal upper-lower limb bursts and enhanced output up to 100%. However, within a given excitatory sensory feedback gain, enhancement due to excitatory interlimb gains could only reach levels up to 20%. Interconnecting four CPGs to have ipsilateral flexor-extensor/extensor-flexor coupling, contralateral flexor-flexor/extensor-extensor coupling, and bilateral flexor-extensor/extensor-flexor coupling could enhance motor output up to 32%. Enhancement observed in experimental data exceeded 32%. Enhancement within this symmetrical four-CPG neural architecture was more sensitive to relatively small interlimb coupling gains. Excitatory sensory feedback gains could produce greater output amplitudes, but larger gains were required for entrainment compared to inhibitory sensory feedback gains. Conclusions Based on these simulations, symmetrical interlimb coupling can account for much, but not all of the excitatory neural coupling between upper and lower limbs during rhythmic locomotor-like movements.

Air pollution exposure represents a major health threat to the developing foetus. DNA methylation is one of the most well-known molecular determinants of the epigenetic status of cells. Blood DNA methylation has been proven sensitive to air pollutants, but the molecular impact of air pollution on new-borns has so far received little attention. We investigated whether nitrogen dioxide (NO 2 ), particulate matter (PM 10 ), temperature and humidity during pregnancy are associated with differences in placental DNA methylation levels. Whole-genome DNA-methylation was measured using the Illumina's Infinium HumanMethylation450 BeadChip in the placenta of 668 newborns from the EDEN cohort. We designed an original strategy using a priori biological information to focus on candidate genes with a specific expression pattern in placenta (active or silent) combined with an agnostic epigenome-wide association study (EWAS). We used robust linear regression to identify CpGs and differentially methylated regions (DMR) associated with each exposure during short- and long-term time-windows. The candidate genes approach identified nine CpGs mapping to 9 genes associated with prenatal NO 2 and PM 10 exposure [false discovery rate (FDR) p < 0.05]. Among these, the methylation level of 2 CpGs located in ADORA2B remained significantly associated with NO 2 exposure during the 2nd trimester and whole pregnancy in the EWAS (FDR p < 0.05). EWAS further revealed associations between the environmental exposures under study and variations of DNA methylation of 4 other CpGs. We further identified 27 DMRs significantly (FDR p < 0.05) associated with air pollutants exposure and 13 DMRs with meteorological conditions. The methylation of ADORA2B, a gene whose expression was previously associated with hypoxia and pre-eclampsia, was consistently found here sensitive to atmospheric pollutants. In addition, air pollutants were associated to DMRs pointing towards genes previously implicated in preeclampsia, hypertensive and metabolic disorders. These findings demonstrate that air pollutants exposure at levels commonly experienced in the European population are associated with placental gene methylation and provide some mechanistic insight into some of the reported effects of air pollutants on preeclampsia.

Motor Neurons Tune Premotor Activity in a Vertebrate Central Pattern Generator

PubMed Central

2017-01-01

Central patterns generators (CPGs) are neural circuits that drive rhythmic motor output without sensory feedback. Vertebrate CPGs are generally believed to operate in a top-down manner in which premotor interneurons activate motor neurons that in turn drive muscles. In contrast, the frog (Xenopus laevis) vocal CPG contains a functionally unexplored neuronal projection from the motor nucleus to the premotor nucleus, indicating a recurrent pathway that may contribute to rhythm generation. In this study, we characterized the function of this bottom-up connection. The X. laevis vocal CPG produces a 50–60 Hz “fast trill” song used by males during courtship. We recorded “fictive vocalizations” in the in vitro CPG from the laryngeal nerve while simultaneously recording premotor activity at the population and single-cell level. We show that transecting the motor-to-premotor projection eliminated the characteristic firing rate of premotor neurons. Silencing motor neurons with the intracellular sodium channel blocker QX-314 also disrupted premotor rhythms, as did blockade of nicotinic synapses in the motor nucleus (the putative location of motor neuron-to-interneuron connections). Electrically stimulating the laryngeal nerve elicited primarily IPSPs in premotor neurons that could be blocked by a nicotinic receptor antagonist. Our results indicate that an inhibitory signal, activated by motor neurons, is required for proper CPG function. To our knowledge, these findings represent the first example of a CPG in which precise premotor rhythms are tuned by motor neuron activity. SIGNIFICANCE STATEMENT Central pattern generators (CPGs) are neural circuits that produce rhythmic behaviors. In vertebrates, motor neurons are not commonly known to contribute to CPG function, with the exception of a few spinal circuits where the functional significance of motor neuron feedback is still poorly understood. The frog hindbrain vocal circuit contains a previously unexplored connection from the motor to premotor region. Our results indicate that motor neurons activate this bottom-up connection, and blocking this signal eliminates normal premotor activity. These findings may promote increased awareness of potential involvement of motor neurons in a wider range of CPGs, perhaps clarifying our understanding of network principles underlying motor behaviors in numerous organisms, including humans.

Understanding the fundamental dynamics of epigenome variation during normal aging is critical for elucidating key epigenetic alterations that affect development, cell differentiation and diseases. Advances in the field of aging and DNA methylation strongly support the aging epigenetic drift model. Although this model aligns with previous studies, the role of other epigenetic marks, such as histone modification, as well as the impact of sampling specific CpGs, must be evaluated. Ultimately, it is crucial to investigate how all CpGs in the human genome change their methylation with aging in their specific genomic and epigenomic contexts. Here, we analyze whole genome bisulfite sequencing DNA methylation maps of brain frontal cortex from individuals of diverse ages. Comparisons with blood data reveal tissue-specific patterns of epigenetic drift. By integrating chromatin state information, divergent degrees and directions of aging-associated methylation in different genomic regions are revealed. Whole genome bisulfite sequencing data also open a new door to investigate whether adjacent CpG sites exhibit coordinated DNA methylation changes with aging. We identified significant ‘aging-segments’, which are clusters of nearby CpGs that respond to aging by similar DNA methylation changes. These segments not only capture previously identified aging-CpGs but also include specific functional categories of genes with implications on epigenetic regulation of aging. For example, genes associated with development are highly enriched in positive aging segments, which are gradually hyper-methylated with aging. On the other hand, regions that are gradually hypo-methylated with aging (‘negative aging segments’) in the brain harbor genes involved in metabolism and protein ubiquitination. Given the importance of protein ubiquitination in proteome homeostasis of aging brains and neurodegenerative disorders, our finding suggests the significance of epigenetic regulation of this posttranslational modification pathway in the aging brain. Utilizing aging segments rather than individual CpGs will provide more comprehensive genomic and epigenomic contexts to understand the intricate associations between genomic neighborhoods and developmental and aging processes. These results complement the aging epigenetic drift model and provide new insights. PMID:26091484

The aim of this study was to explore the realities of everyday nursing practice associated with the implementation of a guideline for the assessment and management of cardiovascular risk. The use of clinical practice guidelines is pivotal to improving health outcomes. However, the implementation of guidelines into practice is complex, unpredictable and, in spite of much investigation, remains resistant to explanation of what works and why. Exploration of the nature of guideline implementation has the potential to illuminate the complexities of guideline implementation by focussing on the nature of practice. Nurses are well placed at the front line of primary health care to contribute to an understanding of how guideline implementation plays out in their everyday practice. Qualitative description was used, involving focus groups and interviews with 32 participants (20 nurses, four doctors, five managers and three funder/planners), to explore the use of a guideline in everyday primary health-care practice. Thematic analysis of data was managed through an inductive process of familiarisation, coding, categorising and generation of themes. Four themes were generated from the data portraying the realities of guideline implementation for primary health-care nurses: self-managing patient, everyday nursing practice, developing new relationships in the health team and impact on health-care delivery. The findings reveal that, even with the best of intentions to implement the guideline, health professionals were frustrated and at a loss as to how to achieve that in practice. Consequently, cardiovascular risk assessment and management was uneven and fragmented. Primary health-care practice environments vary so much that solutions to the difficulties of implementing evidence into practice requires context-specific solution-finding through collaborative teamwork. Furthermore, the attention of guideline developers, health-care policymakers, funders and researchers requires direct focus on the 'how' and the 'what' of evidence implementation.

The aim of this study is the methodological evaluation of Clinical Practice Guidelines (CPG) in hypertension. This is the first in a series of review articles, analysis, assessment in methodology and content of clinical practice guidelines in Cardiology. Of all clinical practice guidelines, three were selected and the Appraisal of Guidelines for Research and Evaluation (AGREE II) instrument was used to assess each guide. The guidelines obtained the lowest score in the domain of applicability (mean 43.8%); while the highest score was for clarity of presentation (mean 81.5%). The lowest percentage was found in the applicability domain (European guideline) and the highest of all scores was found in two domains: scope and purpose, and clarity of presentation (Canadian guideline). Assessing the quality of the clinical practice guidelines analyzed, the Canadian is one with the best scores obtained by applying the AGREE II instrument, and it is advised to be used without modifications.

Although the adherence to stroke guidelines in high-income countries has been shown to be associated with improved patient outcomes, the research, development and implementation of rehabilitation related guidelines in African countries is lacking. The purpose of this article is to describe how a group of front-line practitioners collaborated with academics and students to develop best practice guidelines (BPG) for the management and rehabilitation of stroke in adult patients in Cameroon. A working group was established and adapted internationally recognised processes for the development of best practice guidelines. The group determined the scope of the guidelines, documented current practices, and critically appraised evidence to develop guidelines relevant to the Cameroon context. The primary result of this project is best practice guidelines which provided an overview of the provision of stroke rehabilitation services in the region, and made 83 practice recommendations to improve these services. We also report on the successes and challenges encountered during the process, and the working group's recommendations aimed at encouraging others to consider similar projects. This project demonstrated that there is interest and capacity for improving stroke rehabilitation practices and for stroke guideline development in Africa.

[Clinical practice guidelines (II): searching and critical evaluation].

PubMed

Alonso, P; Bonfill, X

2007-01-01

Clinical practice guidelines have unique characteristics of the Internet era in which they are starting to be increasingly popular. The fact that they are often elaborated by governmental agencies and are not published in conventional journals means that they may not be accessible using the usual search methods employed for other types of scientific studies and documents (clinical trials, reviews, etc.). The Internet has become an essential tool for locating clinical practice guidelines, and meta-search engines, specific databases, directories, and elaborating institutions are of special importance. The relative lack of indexing of clinical practice guides means that Medline and Embase are not as useful in this context as in searching for original studies. With the aim of evaluating the validity, reproducibility, and reliability of clinical practice guidelines, a series of European institutions designed a tool to evaluate clinical practice guidelines at the end of the 1990s. This instrument, named AGREE, aims to offer a framework for the evaluation of the quality of clinical practice guidelines. It can also be useful in the design of new clinical practice guidelines as well as in the evaluation of the validity of guidelines to be updated or adapted. The AGREE instrument has become the reference for those that use guidelines, those that elaborate them, and for healthcare providers.

[How to assess clinical practice guidelines with AGREE II: The example of neonatal jaundice].

Neonatal jaundice is a very frequent condition that occurs in approximately 50-70% of term or near-term (>35 GA) babies in the 1st week of life. In some cases, a high bilirubin blood level can lead to kernicterus. There is no consensus for the management of neonatal jaundice and few countries have published national clinical practice guidelines for the management of neonatal jaundice. The aim of this study was to assess the quality of these guidelines. We conducted a systematic review of the literature for national clinical practice guidelines for the management of neonatal jaundice in term or near-term babies. Four independent reviewers assessed the quality of each guideline using the AGREE II evaluation. For each of the clinical practice guidelines, the management modalities were analyzed (screening, treatment, follow-up, etc.). Seven national clinical practice guidelines were found (South Africa, USA AAP, UK NICE, Canada, Norway, Switzerland, and Israel). The AGREE II score showed widespread variation regarding the quality of these national guidelines. There was no major difference between the guidelines concerning the clinical management of these babies. The NICE guideline is the most valuable guideline regarding the AGREE II score. NICE showed that, despite a strong and rigorous methodology, there is no evidenced-based recommended code of practice (RCP). Comparing RCPs, we found no major differences. The NICE guideline showed the best quality. The AGREE II instrument should be used as a framework when developing clinical practice guidelines to improve the quality of the future guideline. In France, a national guideline is needed for a more standardized management of neonatal jaundice. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

Trichostatin A (TSA), an inhibitor of histone deacetylase, is a well-known antitumor agent that effectively and selectively induces tumor growth arrest and apoptosis. Recently, it was reported that hTERT is one of the primary targets for TSA-induced apoptosis in cancer cells but the mechanism of which has not yet been elucidated. In the present study, to better understand the epigenetic regulation mechanism responsible for the repression of hTERT by TSA, we examined expression of hTERT in the HCT116 colon cancer cell line after treatment with TSA and performed site-specific CpG methylation analysis of the hTERT promoter. We found that TSA-induced the demethylation of site-specific CpGs on the promoter of hTERT, which was caused by down-regulation of DNA methyltransferase 1 (DNMT1). Among the demethylated region, the 31st-33rd CpGs contained a binding site for CTCF, an inhibitor of hTERT transcription. ChIP analysis revealed that TSA-induced demethylation of the 31st-33rd CpGs promoted CTCF binding on hTERT promoter, leading to repression of hTERT. Taken together, down-regulation of DNMT1 by TSA caused demethylation of a CTCF binding site on the hTERT promoter, the result of which was repression of hTERT via recruitment of CTCF to the promoter.

Flight and Walking in Locusts–Cholinergic Co-Activation, Temporal Coupling and Its Modulation by Biogenic Amines

PubMed Central

Rillich, Jan; Stevenson, Paul A.; Pflueger, Hans-Joachim

2013-01-01

Walking and flying in locusts are exemplary rhythmical behaviors generated by central pattern generators (CPG) that are tuned in intact animals by phasic sensory inputs. Although these two behaviors are mutually exclusive and controlled by independent CPGs, leg movements during flight can be coupled to the flight rhythm. To investigate potential central coupling between the underlying CPGs, we used the muscarinic agonist pilocarpine and the amines octopamine and tyramine to initiate fictive flight and walking in deafferented locust preparations. Our data illustrate that fictive walking is readily evoked by comparatively lower concentrations of pilocarpine, whereas higher concentrations are required to elicit fictive flight. Interestingly, fictive flight did not suppress fictive walking so that the two patterns were produced simultaneously. Frequently, leg motor units were temporally coupled to the flight rhythm, so that each spike in a step cycle volley occurred synchronously with wing motor units firing at flight rhythm frequency. Similarly, tyramine also induced fictive walking and flight, but mostly without any coupling between the two rhythms. Octopamine in contrast readily evoked fictive flight but generally failed to elicit fictive walking. Despite this, numerous leg motor units were recruited, whereby each was temporarily coupled to the flight rhythm. Our results support the notion that the CPGs for walking and flight are largely independent, but that coupling can be entrained by aminergic modulation. We speculate that octopamine biases the whole motor machinery of a locust to flight whereas tyramine primarily promotes walking. PMID:23671643

[Purpose] This study aimed to investigate Japanese physical therapists’ attitudes of evidence-based practice and clinical practice guidelines. [Subjects and Methods] In 2014, a cross-sectional postal mail survey using a self-administered questionnaire was conducted. Of 2,982 physical therapists belonging to the Chiba Prefecture Physical Therapist Association, 1,000 were randomly selected. The questionnaire comprised 42 items pertaining to the attitudes of and behavior toward evidence-based practice and clinical practice guidelines. It was investigated to reveal the relationship between clinical practice guidelines/evidence-based practice and therapist characteristics. [Results] The response rate was 39.6%, and 384 questionnaires were available. The main results were as follows: 83.3% participants agreed to the importance of evidence-based practice, 77.1% agree to that evidence-based practice supports clinical decision of physical therapists, and about 11% agreed to have been educated about evidence-based practice. Then, 29.2% used, 54.9% agreed to the importance of, and 13.3% agreed to the utility of clinical practice guidelines. An important factor related mostly to a positive attitude, knowledge and behavior of evidence-based practice and clinical practice guidelines was participating in research activities. [Conclusion] Many of physical therapists do not use and understand the importance of clinical practice guidelines. Participating in research activities may partially contribute to improving these conditions. PMID:28265139

There is a need to critically appraise clinical practice guidelines in order to ensure safe and effective practices are being implemented to optimize patient care. Appraising guidelines within one therapeutic area enable recommendations for improvement during guideline creation and dissemination. Study objectives were to systematically appraise selected published guidelines used in the treatment of pediatric infectious diseases and to make recommendations for improvement throughout the development and dissemination processes. The study occurred between collaborative academic and practice-based institutions located in Canada and Qatar. A literature search identified guidelines for management of pediatric infectious diseases from 1997 to 2013. Each guideline was appraised by four independent assessors, according to the appraisal of guidelines for research and evaluation II (AGREE II) instrument. Standardized domain scores were calculated for each guideline and pooled. Final endorsements for use in clinical practice were also determined. Inter-rater reliability was assessed using intraclass correlation coefficients. Standardized domain scores according to the AGREE II instrument. Twenty guidelines met inclusion criteria and were appraised. Pooled domain scores were: scope and purpose (69.9), stakeholder involvement (40.1), rigour of development (47.1), clarity of presentation (73.4), applicability (23.7), editorial independence (46.7), and overall assessment (55.8). Two (10%) guidelines were recommended for use without revision, 13 (65%) guidelines were recommended with modifications, and 5 (25%) guidelines were not recommended for implementation into practice. Inter-rater reliability was moderate to good with intra-class correlations of 0.65-0.93 per guideline. The majority of appraised guidelines were moderately rated, with a 25% of guidelines not recommended for use. Strategies for improvement require the involvement of all key stakeholders (caregivers, patients, and allied health professionals), and consideration of facilitators, barriers and resource implications during implementation. Additionally, critical appraisal of guidelines should become standard practice prior to adoption into clinical settings.

Financial relationships between organizations that produce clinical practice guidelines and biomedical companies are vulnerable to conflicts of interest. We sought to determine whether organizations that produce clinical practice guidelines have financial relationships with biomedical companies and whether there are associations between organizations' conflict of interest policies and recommendations and disclosures provided in guidelines. We conducted a cross-sectional survey and review of websites of 95 national/international medical organizations that produced 290 clinical practice guidelines published on the National Guideline Clearinghouse website from January 1 to December 31, 2012. Survey responses were available for 68% (65/95) of organizations (167/290 guidelines, 58%), and websites were reviewed for 100% (95/95) of organizations (290/290 guidelines, 100%). In all, 63% (60/95) of organizations producing clinical practice guidelines reported receiving funds from a biomedical company; 80% (76/95) of organizations reported having a policy for managing conflicts of interest. Disclosure statements (disclosing presence or absence of financial relationships with biomedical companies) were available in 65% (188/290) of clinical practice guidelines for direct funding sources to produce the guideline, 51% (147/290) for financial relationships of the guideline committee members, and 1% (4/290) for financial relationships of the organizations producing the guidelines. Among all guidelines, 6% (18/290) disclosed direct funding by biomedical companies, 40% (117/290) disclosed financial relationships between committee members and biomedical companies (38% of guideline committee members, 773/2,043), and 1% (4/290) disclosed financial relationships between the organizations producing the guidelines and biomedical companies. In the survey responses, 60 organizations reported the procedures that they included in their conflict of interest policies (158 guidelines): guidelines produced by organizations reporting more comprehensive conflict of interest policies (per additional procedure, range 5-17) included fewer positive (rate ratio [RR] 0.91, 95% CI 0.86-0.95) and more negative (RR 1.32, 95% CI 1.09-1.60) recommendations regarding patented biomedical products. The clinical practice guidelines produced by organizations reporting more comprehensive conflict of interest policies were also more likely to include disclosure statements for direct funding sources (odds ratio [OR] 1.31, 95% CI 1.10-1.56) and financial relationships of guideline committee members (OR 1.36, 95% CI 1.09-1.79), but not financial relationships of the organizations (0 disclosures). Limitations of the study include the use of the National Guideline Clearinghouse as the single source of clinical practice guidelines and the self-report of survey responses and organizations' website postings. Financial relationships between organizations that produce clinical practice guidelines and biomedical companies are common and infrequently disclosed in guidelines. Our study highlights the need for an effective policy to manage organizational conflicts of interest and disclosure of financial relationships.

In the evidence-to-practice pathway, guidelines are developed to provide a practical summary of evidence and stimulate change. However, when guidelines are used in practice, adherence to the recommendations in guidelines is limited, and adaptations are common. Thus, we need more detailed knowledge about adherence and adaptations when guidelines are used in practice to understand the end of the evidence-to-practice pathway. Subsequently, the aim is to examine adherence to and adaptations of recommendations in the Swedish National Guidelines for Methods of Preventing Disease. A questionnaire was sent to healthcare professionals and managers in Stockholm between January and March 2014. Adherence to the recommendations was compared between practice settings, and the frequency of different adaptations and reasons for adaptations was analysed. Partial adherence to the guidelines was found. The adherence was significantly greater within primary care than at the hospitals (P < .001). Modifications formed the most common category of adaptations (55%) and included mainly prioritization of specific patient groups and increased patient customization. The most common reason for adaptations (25%) was to meet the patients' specific needs and capabilities. This study provides insight into adherence and adaptation when guidelines are used in practice. Work with lifestyle habits was partially done in accordance with the guidelines. Lack of time and lack of resources were not the most common reasons for adaptations. Rather, the findings suggest that when patient needs and capabilities contrast with guideline recommendations, patient needs trump adherence to guidelines. © 2017 John Wiley & Sons, Ltd.

Evidence-based clinical practice guidelines can facilitate proper evaluation and management of concussions in the emergency department (ED), often the initial and primary point of contact for concussion care. There is no universally adopted set of guidelines for concussion management, and extant evidence suggests that there may be variability in concussion care practices and limited application of clinical practice guidelines in the ED. This study surveyed EDs throughout New England to examine current practices of concussion care and utilization of evidence-based clinical practice guidelines in the evaluation and management of concussions. In 2013, a 32-item online survey was e-mailed to 149/168 EDs throughout New England (Connecticut, Rhode Island, Massachusetts, Vermont, New Hampshire, Maine). Respondents included senior administrators asked to report on their EDs use of clinical practice guidelines, neuroimaging decision-making, and discharge instructions for concussion management. Of the 72/78 respondents included, 35% reported absence of clinical practice guidelines, and 57% reported inconsistency in the type of guidelines used. Practitioner preference guided neuroimaging decision-making for 57%. Although 94% provided written discharge instructions, there was inconsistency in the recommended time frame for follow-up care (13% provided no specific time frame), the referral specialist to be seen (25% did not recommend any specialist), and return to activity instructions were inconsistent. There is much variability in concussion care practices and application of evidence-based clinical practice guidelines in the evaluation and management of concussions in New England EDs. Knowledge translational efforts will be critical to improve concussion management in the ED setting.

Background The treatment of head-and-neck cancer is complex and requires the involvement of various health care professionals with a wide range of expertise. We describe the process of developing a practice guideline with recommendations about the organization and delivery of health care services for head-and-neck cancer patients in Alberta. Methods Outcomes of interest included composition of the health care team, qualification requirements for team members, cancer centre and team member volumes, infrastructure needs, and wait times. A search for existing practice guidelines and a systematic review of the literature addressing the organization and delivery of health care services for head-and-neck cancer patients were conducted. The search included the Standards and Guidelines Evidence (sage) directory of cancer guidelines and PubMed. Results One practice guideline was identified for adaptation. Three additional practice guidelines provided supplementary evidence to inform guideline recommendations. Members of the Alberta Provincial Head and Neck Tumour Team (consisting of various health professionals from across the province) provided expert feedback on the adapted recommendations through an online and in-person review process. Selected experts in head-and-neck cancer from outside the province participated in an external online review. SUMMARY The recommendations outlined in this practice guideline are based on existing guidelines that have been modified to fit the Alberta context. Although specific to Alberta, the recommendations lend credence to similar published guidelines and could be considered for use by groups lacking the resources of appointed guideline panels. The recommendations are meant to be a guide rather than a fixed protocol. The implementation of this practice guideline will depend on many factors, including but not limited to availability of trained personnel, adequate funding of infrastructure, and collaboration with other associations of health care professionals in the province.

To explore the difficulties and strategies regarding guideline implementation among emergency nurses. Emerging infectious diseases remain an underlying source of global health concern. Guidelines for accident and emergency departments would require adjustments for infectious disease management. However, disparities between guidelines and nurses' practice are frequently reported, which undermines the implementation of these guidelines into practice. This article explores the experience of frontline emergency nurses regarding guideline implementation and provides an in-depth account of their strategies in bridging guideline-practice gaps. A qualitative descriptive design was used. Semi-structured, face-to-face, individual interviews were conducted between November 2013-May 2014. A purposive sample of 12 frontline emergency nurses from five accident and emergency departments in Hong Kong were recruited. The audio-recorded interviews were transcribed verbatim and analysed with a qualitative content analysis approach. Four key categories associated with guideline-practice gaps emerged, including getting work done, adapting to accelerated infection control measures, compromising care standards and resolving competing clinical judgments across collaborating departments. The results illustrate that the guideline-practice gaps could be associated with inadequate provision of corresponding organisational supports after guidelines are established. The nurses' experiences have uncovered the difficulties in the implementation of guidelines in emergency care settings and the corresponding strategies used to address these problems. The nurses' experiences reflect their endeavour in adjusting accordingly and adapting themselves to their circumstances in the face of unfeasible guidelines. It is important to customise guidelines to the needs of frontline nurses. Maintaining cross-departmental consensus on guideline interpretation and operation is also indicated as an important component for effective guideline implementation. © 2016 John Wiley & Sons Ltd.

Olguin, Abel

Hypersonic Glide Vehicles (HGVs) are a type of reentry vehicle that couples the high speed of ballistic missiles with the maneuverability of aircraft. The HGV has been in development since the 1970s, and its technology falls under the category of Conventional Prompt Global Strike (CPGS) weapons. As noted by James M. Acton, a senior associate in the Nuclear Policy Program at the Carnegie Endowment, CPGS is a “missile in search of a mission.” With the introduction of any significant new military capability, a doctrine for use—including specifics regarding how, when and where it would be used, as well as tactics,more » training and procedures—must be clearly defined and understood by policy makers, military commanders, and planners. In this paper, benefits and limitations of the HGV are presented. Proposed criteria and four scenarios illustrate a possible method for assessing when to use an HGV.« less

Background Financial relationships between organizations that produce clinical practice guidelines and biomedical companies are vulnerable to conflicts of interest. We sought to determine whether organizations that produce clinical practice guidelines have financial relationships with biomedical companies and whether there are associations between organizations’ conflict of interest policies and recommendations and disclosures provided in guidelines. Methods and Findings We conducted a cross-sectional survey and review of websites of 95 national/international medical organizations that produced 290 clinical practice guidelines published on the National Guideline Clearinghouse website from January 1 to December 31, 2012. Survey responses were available for 68% (65/95) of organizations (167/290 guidelines, 58%), and websites were reviewed for 100% (95/95) of organizations (290/290 guidelines, 100%). In all, 63% (60/95) of organizations producing clinical practice guidelines reported receiving funds from a biomedical company; 80% (76/95) of organizations reported having a policy for managing conflicts of interest. Disclosure statements (disclosing presence or absence of financial relationships with biomedical companies) were available in 65% (188/290) of clinical practice guidelines for direct funding sources to produce the guideline, 51% (147/290) for financial relationships of the guideline committee members, and 1% (4/290) for financial relationships of the organizations producing the guidelines. Among all guidelines, 6% (18/290) disclosed direct funding by biomedical companies, 40% (117/290) disclosed financial relationships between committee members and biomedical companies (38% of guideline committee members, 773/2,043), and 1% (4/290) disclosed financial relationships between the organizations producing the guidelines and biomedical companies. In the survey responses, 60 organizations reported the procedures that they included in their conflict of interest policies (158 guidelines): guidelines produced by organizations reporting more comprehensive conflict of interest policies (per additional procedure, range 5–17) included fewer positive (rate ratio [RR] 0.91, 95% CI 0.86–0.95) and more negative (RR 1.32, 95% CI 1.09–1.60) recommendations regarding patented biomedical products. The clinical practice guidelines produced by organizations reporting more comprehensive conflict of interest policies were also more likely to include disclosure statements for direct funding sources (odds ratio [OR] 1.31, 95% CI 1.10–1.56) and financial relationships of guideline committee members (OR 1.36, 95% CI 1.09–1.79), but not financial relationships of the organizations (0 disclosures). Limitations of the study include the use of the National Guideline Clearinghouse as the single source of clinical practice guidelines and the self-report of survey responses and organizations’ website postings. Conclusions Financial relationships between organizations that produce clinical practice guidelines and biomedical companies are common and infrequently disclosed in guidelines. Our study highlights the need for an effective policy to manage organizational conflicts of interest and disclosure of financial relationships. PMID:27244653

Clinical guidelines are considered to be essential for improving quality and safety of health care. However, interventions to promote implementation of guidelines have demonstrated only partial effectiveness and the reasons for this apparent failure are not yet fully understood. To investigate how GPs implement clinical guidelines in everyday clinical practice and how implementation approaches differ between practices. Individual semi-structured open-ended interviews with seven GPs who were purposefully sampled with regard to gender, age and practice form. Interviews were recorded, transcribed verbatim and then analysed using systematic text condensation. Analysis of the interviews revealed three different approaches to the implementation of guidelines in clinical practice. In some practices the GPs prioritized time and resources on collective implementation activities and organized their everyday practice to support these activities. In other practices GPs discussed guidelines collectively but left the application up to the individual GP whilst others again saw no need for discussion or collective activities depending entirely on the individual GP's decision on whether and how to manage implementation. Approaches to implementation of clinical guidelines vary substantially between practices. Supporting activities should take this into account. © The Author 2015. Published by Oxford University Press.

Intensive-care practices and settings may differ for India in comparison to other countries. While international guidelines are available to direct the use of enteral nutrition (EN), there are no recommendations specific to Indian settings. Advisory board meetings were arranged to develop the practice guidelines specific to Indian context, for the use of EN in critically ill patients and to overcome challenges in this field. Various existing guidelines, meta-analyses, randomized controlled trials, controlled trials, and review articles were reviewed for their contextual relevance and strength. A systematic grading of practice guidelines by advisory board was done based on strength of the supporting evidence. Wherever Indian studies were not available, references were taken from the international guidelines. Based on the literature review, the recommendations for developing the practice guidelines were made as per the grading criteria agreed upon by the advisory board. The recommendations were to address challenges regarding EN versus parenteral nutrition; nutrition screening and assessment; nutrition in hemodynamically unstable; route of nutrition; tube feeding and challenges; tolerance; optimum calorie-protein requirements; selection of appropriate enteral feeding formula; micronutrients and immune-nutrients; standard nutrition in hepatic, renal, and respiratory diseases and documentation of nutrition practices. This paper summarizes the optimum nutrition practices for critically ill patients. The possible solutions to overcome the challenges in this field are presented as practice guidelines at the end of each section. These guidelines are expected to provide guidance in critical care settings regarding appropriate critical-care nutrition practices and to set up Intensive Care Unit nutrition protocols.

Objectives To assess attitudes of ICU staff members toward practice guidelines in general and toward a specific guideline, CDC's Guideline for Hand Hygiene in Healthcare Settings; to correlate these attitudes with staff and hospital characteristics; and to examine the impact of staff attitudes toward the Hand Hygiene Guideline on self reported implementation of the Guideline. Methods A cross-sectional survey of staff in 70 ICUs in 39 U.S. hospitals, members of The National Nosocomial Infection Surveillance (NNIS) System. A survey, “Attitudes Regarding Practice Guidelines”, was administered anonymously to all willing staff during a site visit at each hospital; 1,359 ICU personnel: 1,003 nurses (74%), 228 physicians (17%), and 128 others (10%) responded. Results Significantly more positive attitudes toward practice guidelines were found among staff in pediatric as compared with adult ICUs (p<0.001). Nurses and other staff when compared with physicians had more positive attitudes toward guidelines in general but not toward the specific Hand Hygiene Guideline. Those with more positive attitudes were significantly more likely to report that they had implemented recommendations of the Guideline (p<0.001) and used an alcohol product for hand hygiene (p=0.002). Conclusions The majority of staff members were familiar with the CDC Hand Hygiene Guideline. Staff attitudes toward practice guidelines varied by type of ICU and by profession, and more positive attitudes were associated with significantly better self-reported guideline implementation. Because differences in staff attitudes might hinder or facilitate their acceptance and adoption of evidence-based practice guidelines, these results may have important implications for the education and/or socialization of ICU staff.

The development of guidelines and standards for telemedicine is an important and valuable process to help insure effective and safe delivery of quality healthcare. Some organizations, such as the American Telemedicine Association (ATA), have made the development of standards and guidelines a priority. The practice guidelines developed so far have been well received by the telemedicine community and are being adopted in numerous practices, as well as being used in research to support the practice and growth of telemedicine. Studies that utilize published guidelines not only help bring them into greater public awareness, but they also provide evidence needed to validate existing guidelines and guide the revision of future versions. Telemedicine will continue to grow and be adopted by more healthcare practitioners and patients in a wide variety of forms not just in the traditional clinical environments, and practice guidelines will be a key factor in fostering this growth. Creation of guidelines is important to payers and regulators as well as increasingly they are adopting and integrating them into regulations and policies. This paper will review some of the recent ATA efforts in developing telemedicine practice guidelines, review the role of research in guidelines development, review data regarding their use, and discuss some of areas where guidelines are still needed.

Chronic psychological stress is associated with accelerated aging and increased risk for aging-related diseases, but the underlying molecular mechanisms are unclear. We examined the effect of lifetime stressors on a DNA methylation-based age predictor, epigenetic clock. After controlling for blood cell-type composition and lifestyle parameters, cumulative lifetime stress, but not childhood maltreatment or current stress alone, predicted accelerated epigenetic aging in an urban, African American cohort (n = 392). This effect was primarily driven by personal life stressors, was more pronounced with advancing age, and was blunted in individuals with higher childhood abuse exposure. Hypothesizing that these epigenetic effects could be mediated by glucocorticoid signaling, we found that a high number (n = 85) of epigenetic clock CpG sites were located within glucocorticoid response elements. We further examined the functional effects of glucocorticoids on epigenetic clock CpGs in an independent sample with genome-wide DNA methylation (n = 124) and gene expression data (n = 297) before and after exposure to the glucocorticoid receptor agonist dexamethasone. Dexamethasone induced dynamic changes in methylation in 31.2 % (110/353) of these CpGs and transcription in 81.7 % (139/170) of genes neighboring epigenetic clock CpGs. Disease enrichment analysis of these dexamethasone-regulated genes showed enriched association for aging-related diseases, including coronary artery disease, arteriosclerosis, and leukemias. Cumulative lifetime stress may accelerate epigenetic aging, an effect that could be driven by glucocorticoid-induced epigenetic changes. These findings contribute to our understanding of mechanisms linking chronic stress with accelerated aging and heightened disease risk.

The utility and reliability of assessing molecular biomarkers for translational applications on pre-operative core biopsy specimens assume consistency of molecular profiles with larger surgical specimens. Whether DNA methylation in ductal carcinoma in situ (DCIS), measured in core biopsy and surgical specimens are similar, remains unclear. Here, we compared genome-scale DNA methylation measured in matched core biopsy and surgical specimens from DCIS, including specific DNA methylation biomarkers of subsequent invasive cancer. DNA was extracted from guided 2mm cores of formalin fixed paraffin embedded (FFPE) specimens, bisulfite-modified, and measured on the Illumina HumanMethylation450 BeadChip. DNA methylation profiles of core biopsies exhibited high concordance with matched surgical specimens. Within-subject variability in DNA methylation was significantly lower than between-subject variability (all P<2.20E-16). In 641 CpGs whose methylation was related with increased hazard of invasive breast cancer, lower within-subject than between-subject variability was observed in 92.3% of the study participants (P<0.05). Between patient-matched core biopsy and surgical specimens, <0.6% of CpGs measured had changes in median DNA methylation >15%, and a pathway analysis of these CpGs indicated enrichment for genes related with wound healing. Our results indicate that DNA methylation measured in core biopsies are representative of the matched surgical specimens and suggest that DCIS biomarkers measured in core biopsies can inform clinical decision-making.

1999-03-01

Rural health care workforce forecasting has not included adjustments for predictable changes in practice patterns, such as the introduction of practice guidelines. To estimate the impact of a practice guideline for a single health condition on the needs of a rural health professional workforce. The current care of a cohort of rural Medicare recipients with diabetes mellitus was compared with the care recommended by a diabetes practice guideline. The additional tests and visits that were needed to comply with the guideline were translated into additional hours of physician services and total physician full-time equivalents. The implementation of a practice guideline for Medicare recipients with diabetes in rural Minnesota would require over 30,000 additional hours of primary care physician services and over 5,000 additional hours of eye care professionals' time per year. This additional need represents a 1.3% to 2.4% increase in the number of primary care physicians and a 1.0% to 6.6% increase in the number of eye-care clinicians in a state in which the rural medical provider to population ratios already meet some recommended workforce projections. The implementation of practice guidelines could result in an increased need for rural health care physicians or other providers. That increase, caused by guideline implementation, should be accounted for in future rural health care workforce predictions.

The efficacy of corticosteroid and hyaluronic acid injections for knee osteoarthritis has been questioned. The purpose of this study was to determine the impact of the American Academy of Orthopaedic Surgeons (AAOS) clinical practice guidelines on the use of these injections in the United States and determine if utilization differed by provider specialty. Patients with knee osteoarthritis were identified within the Humana database from 2007 to 2015, and the percentage of patients receiving a knee injection relative to the number of patients having an encounter for knee osteoarthritis was calculated and was trended for the study period. The impact of each edition of the AAOS clinical practice guidelines on injection use was evaluated with segmented regression analysis. Injection trends were also analyzed relative to the specialty of the provider performing the injection. Of 1,065,175 patients with knee osteoarthritis, 405,101 (38.0%) received a corticosteroid injection and 137,005 (12.9%) received a hyaluronic acid injection. The rate of increase in hyaluronic acid use, per 100 patients with knee osteoarthritis, decreased from 0.15 to 0.07 injection per quarter year (p = 0.02) after the first clinical practice guideline, and the increase changed to a decrease at a rate of -0.12 injection per quarter (p < 0.001) after the second clinical practice guideline. After the first clinical practice guideline, the rate of increase in utilization of corticosteroids, per 100 patients with knee osteoarthritis, significantly lessened to 0.12 injection per quarter (p < 0.001), and after the second clinical practice guideline, corticosteroid injection use plateaued (p = 0.72). The trend in use of hyaluronic acid injections by orthopaedic surgeons and pain specialists decreased with time following the second-edition clinical practice guideline but did not change for primary care physicians or nonoperative musculoskeletal providers. Subtle but significant changes in hyaluronic acid and corticosteroid injections occurred following the publication of both clinical practice guidelines. Although the clinical practice guidelines did impact injection use, given the high costs of these injections and their questionable clinical efficacy, further interventions beyond publishing clinical practice guidelines are needed to encourage higher-value care for patients with knee osteoarthritis.

Objective: Several countries have developed Clinical Practice Guidelines regarding treatment of perinatal depressive symptoms and perinatal use of antidepressant. We aimed to compare guidelines to guide clinicians in best clinical practice. Methods: An extensive search in guideline databases, MEDLINE and PsycINFO was performed. When no guidelines were (publicly) available online, we contacted psychiatric-, obstetric-, perinatal- and mood disorder societies of all first world countries and the five largest second world countries. Only Clinical Practice Guidelines adhering to quality criteria of the Appraisal of Guidelines for Research and Evaluation instrument and including a systematic review of evidence were included. Data extraction focussed on recommendations regarding continuation or withdrawal of antidepressants and preferred treatment in newly depressed patients. Results: Our initial search resulted in 1094 articles. After first screening, 40 full-text articles were screened. Of these, 24 were excluded for not being an official Clinical Practice Guidelines. In total, 16 Clinical Practice Guidelines were included originating from 12 countries. Eight guidelines were perinatal specific and eight were general guidelines. Conclusion: During pregnancy, four guidelines advise to continue antidepressants, while there is a lack of evidence supporting this recommendation. Five guidelines do not specifically advise or discourage continuation. For new episodes, guidelines agree on psychotherapy (especially cognitive behavioural therapy) as initial treatment for mild to moderate depression and antidepressants for severe depression, with a preference for sertraline. Paroxetine is not preferred treatment for new episodes but switching antidepressants for ongoing treatment is discouraged (three guidelines). If mothers use antidepressants, observation of the neonate is generally recommended and breastfeeding encouraged. PMID:29506399

Applying clinical guidelines in general practice: a qualitative study of potential complications.

Clinical guidelines for single diseases often pose problems in general practice work with multimorbid patients. However, little research focuses on how general practice is affected by the demand to follow multiple guidelines. This study explored Norwegian general practitioners' (GPs') experiences with and reflections upon the consequences for general practice of applying multiple guidelines. Qualitative focus group study carried out in Mid-Norway. The study involved a purposeful sample of 25 Norwegian GPs from four pre-existing groups. Interviews were audio-recorded, transcribed and analyzed using systematic text condensation, i.e. applying a phenomenological approach. The GPs' responses clustered around two major topics: 1) Complications for the GPs of applying multiple guidelines; and, 2) Complications for their patients when GPs apply multiple guidelines. For the GPs, applying multiple guidelines created a highly problematic situation as they felt obliged to implement guidelines that were not suited to their patients: too often, the map and the terrain did not match. They also experienced greater insecurity regarding their own practice which, they admitted, resulted in an increased tendency to practice 'defensive medicine'. For their patients, the GPs experienced that applying multiple guidelines increased the risk of polypharmacy, excessive non-pharmacological recommendations, a tendency toward medicalization and, for some, a reduction in quality of life. The GPs experienced negative consequences when obliged to apply a variety of single disease guidelines to multimorbid patients, including increased risk of polypharmacy and overtreatment. We believe patient-centered care and the GPs' courage to non-comply when necessary may aid in reducing these risks. Health care authorities and guideline developers need to be aware of the potential negative effects of applying a single disease focus in general practice, where multimorbidity is highly prevalent.

Medical Malpractice Implications of Clinical Practice Guidelines.

Clinical practice guidelines aim to improve medical care by clarifying and making useful recommendations to providers. Although providers should account for patients' unique characteristics when determining a treatment plan, it is generally perceived as good practice to follow guidelines when applicable. This is of interest in malpractice litigation, where it is essential to establish a standard of care to evaluate the performances of providers. Although the opinions of expert witnesses are used to determine standards of care, guidelines are expected to play a leading role. Guidelines alone should not establish a legal standard but may help inform this discussion in the courtroom. Therefore, it is incumbent that excellent, practical, and timely guidelines are continually created and updated in a transparent way. These guidelines must be very clear and underscore the various strengths of recommendation based on the quality of available evidence.

Japanese Society of Neurology (JSN) published Practical guideline for Parkinson's Disease (PD) in 2002 and revised version in 2012. This guideline was prepared according to the method of evidence-based medicine. We surveyed the daily practice of PD to expert neurologists for PD nationwide in Japan. Many specialists for PD reported that patients with PD had poor treatment by neurologists and neurosurgeons that was out of PD practical guideline. Some patients were treated with small dose levodopa despite of Hoehn-Yahr 3 stage. Another disabled patients were treated with dopamine agonists alone despite of over aged of 80. Many neurologists treated PD patients out of guideline. It is important to educate guideline to neurologists and general practioner.

Chronic obstructive pulmonary disease (COPD) is a complex chronic lung disease characterised by progressive fixed airflow limitation and acute exacerbations that frequently require hospitalisation. Evidence-based clinical guidelines for the diagnosis and management of COPD are now widely available. However, the uptake of these COPD guidelines in clinical practice is highly variable, as is the case for many other chronic disease guidelines. Studies have identified many barriers to implementation of COPD and other guidelines, including factors such as lack of familiarity with guidelines amongst clinicians and inadequate implementation programs. Several methods for enhancing adherence to clinical practice guidelines have been evaluated, including distribution methods, professional education sessions, electronic health records (EHR), point of care reminders and computer decision support systems (CDSS). Results of these studies are mixed to date, and the most effective ways to implement clinical practice guidelines remain unclear. Given the significant resources dedicated to evidence-based medicine, effective dissemination and implementation of best practice at the patient level is an important final step in the process of guideline development. Future efforts should focus on identifying optimal methods for translating the evidence into everyday clinical practice to ensure that patients receive the best care. PMID:25478199

Evidence-based guidelines in clinical oncology practice are now prominent, with emphasis on clinical, health outcome and economic perspectives. Given the complexity of cancer management, a multidisciplinary approach is essential. Evidence-based guidelines to address supportive cancer care have merged expert opinion, systematic evaluation of clinical and research data, and meta-analyses of clinical trials. Production of supportive care guidelines by the interdisciplinary team is dependent on sufficient high-quality research studies. Once published, it is essential they be customized at institutional and national levels. Implementation in clinical practice is perhaps the greatest challenge. Optimal management occurs through integration of country-specific issues, including care access, healthcare resources, information technology, and national coordination of healthcare practices. The purpose of this article is to: (1) provide an overview of interdisciplinary cancer management using evidence-based guidelines; (2) delineate the theory and practice of guideline dissemination, utilization and outcome assessment; and (3) recommend future research strategies to maximize guidelines use in clinical practice.

To assess Canadian physicians' confidence in, attitudes about and preferences regarding clinical practice guidelines. Cross-sectional, self-administered mailed survey. Stratified random sample of 3000 Canadian physicians; 1878 (62.6%) responded. Canada. Physicians' use of various information sources; familiarity with and confidence in guidelines; attitudes about guidelines and their effect on medical care; rating of importance of guidelines and other sources of information in clinical decision-making; rating of importance of various considerations in deciding whether to adopt a set of guidelines; and rating of usefulness of different formats for presenting guidelines. In all, 52% of the respondents reported using guidelines at least monthly, substantially less frequently than traditional information sources. Most of the respondents expressed confidence in guidelines issued by various physician organizations, but 51% to 77% were not confident in guidelines issued by federal or provincial health ministries or by health insurance plans. The respondents were generally positive about guidelines (e.g., over 50% strongly agreed that they are a convenient source of advice and good educational tools); however, 22% to 26% had concerns about loss of autonomy, the rigidity of guidelines and decreased satisfaction with medical practice. Endorsement by respected colleagues or major organizations was identified as very important by 78% and 62% of the respondents respectively in deciding whether to adopt a set of guidelines in their practice. User friendliness of the guidelines format was thought to be very important by 62%; short pamphlets, manuals summarizing a number of guidelines, journal articles and pocket cards summarizing guidelines were the preferred formats (identified as most useful by 50% to 62% of the respondents). Canadian physicians, although generally positive about guidelines and confident in those developed by clinicians, have not yet integrated the use of guidelines into their practices to a large extent. Our results suggest that respected organizations and opinion leaders should be involved in the development of guidelines and that the acceptability of any proposed format and medium for guidelines presentation should be pretested.

Maintaining oral hygiene is a key component of preventing ventilator-associated pneumonia; however, practices are inconsistent. To explore how characteristics of institutional guidelines for oral hygiene influence nurses' oral hygiene practices and perceptions of that practice. Oral hygiene section of a larger survey study on prevention of ventilator-associated pneumonia. Critical care nurses at 8 hospitals in Northern California that had more than 1000 ventilator days in 2009 were recruited to participate in the survey. Twenty-one questions addressed oral hygiene practices and practice perceptions. Descriptive statistics, analysis of variance, and Spearman correlations were used for analyses. A total of 576 critical care nurses (45% response rate) responded to the survey. Three types of institutional oral hygiene guidelines existed: nursing policy, order set, and information bulletin. Nursing policy provided the most detail about the oral hygiene care; however, adherence, awareness, and priority level were higher with order sets (P < .05). The content and method of disseminating these guidelines varied, and nursing practices were affected by these differences. Nurses assessed the oral cavity and used oral swabs more often when those practices were included in institutional guidelines. The content and dissemination method of institutional guidelines on oral hygiene do influence the oral hygiene practices of critical care nurses. Future studies examining how institutional guidelines could best be incorporated into routine workflow are needed. ©2015 American Association of Critical-Care Nurses.

Developing Practice Guidelines for Psychoanalysis

Consensus-based practice guidelines codify clinical intelligence and the rich oral tradition in medicine. Because they reflect actual practice, they are readily accepted by clinicians as a basis for external review. This article illustrates the development of guidelines for a psychoanalytic approach to the large pool of patients who present with a depression. It suggests an integrated biopsychosocial approach to these individuals that is useful in current practice, and it offers propositions that may be tested in future research undertakings. Eventually, practice guidelines such as these may form the basis of economical systems of health care that avoid arbitrary, clinically untenable limitations on services. PMID:22700290

Lenz, Janelle R; Degnan, Daniel D; Hertig, John B; Stevenson, James G

In 2015, the Institute for Safe Medication Practices (ISMP) released safe practice guidelines for adult intravenous (IV) push medications. ISMP's most recent set of guidelines has added to a growing list of recommendations from professional groups on the safe use of IV medications. These recommendations and guidelines vary with regard to their audience, scope, and terminology. In some ways, these variations may contribute to confusion and delayed adoption of the standards. This report attempts to provide clarity about the rationale and background regarding the need for practice improvement, discussion of various guidelines, and practice mitigation strategies to improve patient safety.

Major opportunity exists to better align clinical science and clinical practice. To do so will require efforts not only to develop clinical practice guidelines, but to facilitate their application in practice. The American College of Cardiology operates a program to develop and assess the effectiveness of tools that facilitate the application of guidelines in practice. Here we review what we have learned about the process of guideline implementation, lay out the major research questions that need to be addressed, and argue that professional societies play a critical role in moving from guideline development to application.

Adherence To Diabetes Mellitus Treatment Guidelines From Theory To Practice: The Missing Link.

PubMed

Hashmi, Noreen Rahat; Khan, Shahzad Ali

2016-01-01

Diabetes mellitus is a complex multisystem disease that requires high quality care. Clinical practice guidelines help physicians and patients make the best possible health care decisions and improve health care management of diabetic patients. These guidelines provide the norms for clinical management as well as monitoring of diabetes care. They are not simple algorithms but are based on structured evidence based diabetic management protocols developed from randomized controlled trials. Despite the widespread availability of this diabetic guideline, their use is suboptimal at best. There are several factors blamed for contributing to this missing link from available theoretical guideline recommendations to practical applications of these guidelines. We present a brief review based on available literature review for an ongoing interventional study being done by authors in two tertiary care hospital in Lahore Pakistan for improving adherence to diabetes guidelines. We will discuss guideline implementation cycle and also present a framework encompassing various factors involved in adherence to guidelines. Until recently the emphasis to improve the guideline adherence targeted the factors relating to individual health care professionals in reference to their knowledge, attitude practice of the guidelines. However, we will discuss that broader range of health care systems, organizational factors, and factors relating to patients which may also significantly impact the adherence to the guidelines. The framework emphasises that it is important to understand the factors that act as barriers and contribute to the missing link between theory and practice of diabetic guidelines. This will help plan appropriate strategies in the pre-implementation stage for effective and improved diabetes guidelines adherence and management.

To assess the quality of guidelines published in peer-reviewed literature concerning the role of physiotherapy in the management of patients with RA. A systematic literature search for clinical practice guidelines that included physiotherapy interventions was performed in four electronic databases. We assessed the quality of the selected guidelines using the appraisal of guidelines for research and evaluation (AGREE) instrument. In addition, the recommendations of guidelines with the highest quality scores were summarized. Eight clinical practice guidelines fulfilled the inclusion criteria. Scope/purpose was the most often adequately addressed AGREE domain (in seven of the eight guidelines) and applicability the least (in two of the eight guidelines). Based on the AGREE domain scores, six guidelines could be recommended or strongly recommended for clinical use. Five out of these six (strongly) recommended guidelines included a recommendation on exercise therapy and/or patient education, with these interventions being recommended in every case. Transcutaneous electrical nerve stimulation and thermotherapy were recommended in four of these six guidelines. US, thermotherapy, low-level laser therapy, massage, passive mobilization and balneotherapy were addressed in one or two of these six guidelines. Six of eight clinical practice guidelines addressing physiotherapy interventions were recommended or strongly recommended according to the AGREE instrument. In general, guideline recommendations on physiotherapy intervention, from both the recommended guidelines as well as from the not recommended guidelines, lacked detail concerning mode of delivery, intensity, frequency and duration.

Inherent in the care provided to patients with cancer is an important psychosocial element which has been explored scientifically through qualitative research. The purpose of our study was to evaluate the availability of qualitative research in gynaecologic oncology and to measure its integration in gynaecologic oncology practice guidelines. We searched Medline, CINHAL, Scopus, and Web of Science databases to identify the availability of qualitative research conducted in the past 20 years on the three most prevalent gynaecologic cancers: endometrial, ovarian, and cervical cancer. National and international practice guidelines on management of gynaecologic cancers were selected using the National Guideline Clearinghouse website, the Society of Obstetricians and Gynaecologists of Canada website, and the Standards and Guidelines Evidence directory of cancer guidelines. Bibliometric analysis was used to determine the frequency of qualitative references cited in these guidelines. One hundred thirteen qualitative research papers on gynaecologic cancers were identified focusing on psychological impacts, social dynamics, and doctor-patient interactions during cancer treatment and recovery. Among the 15 national and international clinical practice guidelines identified on management of gynaecologic cancer, there were a total of 2272 references, and of these only three references citing qualitative research were identified (0.1%) in only one of the 15 practice guidelines. Although qualitative research is being carried out in gynaecologic oncology, its integration into clinical practice guidelines is essentially absent. Efforts to narrow the gap between qualitative research and clinical practice are essential in ensuring a comprehensive approach to the treatment of patients with gynaecologic cancer.

Limited attention is directed to the potential conflicts of interest (COI) of the authors of practice guidelines writing groups of professional medical societies (PMS) and industry. The objective of this study was to report the proportion of authors with potential COI among guidelines writing groups of PMS. A systematic search in PubMed to identify practice guidelines of a convenience sample of 12 publicly known PMS for a period of 3 years. The authors' disclosures of COI were reviewed for the identified guidelines. We identified 126 guidelines, of which 107 (85%) reported authors' disclosures of COI and 19 (15%) did not. With the exception of the US Preventive Services Task Force, all of the reviewed guidelines writing groups of PMS had potential COI to some extent. The maximum percentage of authors with potential COI varied among PMS from 25% to 100%. A substantial variation of percentage of authors with potential COI exists among guidelines writing groups of different PMS. Several practice guidelines of PMS fail to include the disclosures of potential COI in their published guidelines. We made several suggestions to promote the transparency of potential COI in clinical practice guidelines.

The goal of this project was to develop evidence- and consensus-based practice guidelines for psychological interventions in the rehabilitation of patients with oncological disease (breast, prostate, or colorectal cancer). First of all, we conducted a literature search and survey of all oncological rehabilitation centers in Germany (N = 145) to obtain a thorough perspective of the recent evidence, guidelines, the structural framework, and practice of psychological services in oncological rehabilitation. Next, an expert workshop was held with national experts from scientific departments, clinicians from rehabilitation centers, and patients. In this workshop, we drafted and agreed upon an initial version of the practice guidelines. Afterwards, the practice guidelines were sent to all head physicians and senior psychologists at oncological rehabilitation centers in Germany for approval (N = 280 questionnaires). In addition, key recommendations were discussed with a group of rehabilitation patients. Finally, the practice guidelines were revised by the expert panel and made available online to the public. The practice guidelines have been widely accepted by both the expert panel and the surveyed clinicians and patients. They include recommendations for psycho-oncological interventions that should be offered to all rehabilitation patients with breast, prostate, or colorectal cancer. They also comprise recommendations for specific problem areas concerning psychological functions, body functions, and environmental and personal factors. The practice guidelines provide detailed recommendations for high-quality psychosocial care in an oncological rehabilitation context. It is their aim to guide the multidisciplinary team, especially psychologists and physicians, in their daily practice. Copyright © 2016 John Wiley & Sons, Ltd.

dementia is a highly prevalent acquired cognitive disorder that interferes with activities of daily living, relationships and quality of life. Recognition and effective management strategies are necessary to provide comprehensive care for these patients and their families. High-quality clinical practice guidelines can improve the quality and consistency of care in all aspects of dementia diagnosis and management by clarifying interventions supported by sound evidence and by alerting clinicians to interventions without proven benefit. we aimed to offer a synthesis of existing practice recommendations for the diagnosis and management of dementia, based upon moderate-to-high quality dementia guidelines. we performed a systematic search in EMBASE and MEDLINE as well as the grey literature for guidelines produced between 2008 and 2013. thirty-nine retrieved practice guidelines were included for quality appraisal by the Appraisal of Guidelines Research and Evaluation II (AGREE-II) tool, performed by two independent reviewers. From the 12 moderate-to-high quality guidelines included, specific practice recommendations for the diagnosis and/or management of any aspect of dementia were extracted for comparison based upon the level of evidence and strength of recommendation. there was a general agreement between guidelines for many practice recommendations. However, direct comparisons between guidelines were challenging due to variations in grading schemes. © The Author 2014.

One way to facilitate the translation of research into the occupational health service practice is through clinical practice guidelines. To increase the implementability of guidelines it is important to include the end-users in the development, for example by a community of practice approach. This paper describes the development of an occupational health practice guideline aimed at the management of non-specific low back pain (LBP) by using a community of practice approach. The paper also includes a process evaluation of the development providing insight into the feasibility of the process. A multidisciplinary community of practice group (n = 16) consisting of occupational nurses, occupational physicians, ergonomists/physical therapists, health and safety engineers, health educators, psychologists and researchers from different types of occupational health services and geographical regions within Sweden met eleven times (June 2012-December 2013) to develop the practice guideline following recommendations of guideline development handbooks. Process-outcomes recruitment, reach, context, satisfaction, feasibility and fidelity were assessed by questionnaire, observations and administrative data. Group members attended on average 7.5 out of 11 meetings. Half experienced support from their workplace for their involvement. Feasibility was rated as good, except for time-scheduling. Most group members were satisfied with the structure of the process (e.g. presentations, multidisciplinary group). Fidelity was rated as fairly high. The described development process is a feasible process for guideline development. For future guideline development expectations of the work involved should be more clearly communicated, as well as the purpose and tasks of the CoP-group. Moreover, possibilities to improve support from managers and colleagues should be explored. This paper has important implications for future guideline development; it provides valuable information on how practitioners can be included in the development process, with the aim of increasing the implementability of the developed guidelines.

Background The diffusion of national evidence-based practice guidelines and their impact on patient outcomes often go unmeasured. Methods Our objectives were to (1) evaluate implementation and compliance with clinical practices recommended in the new Centers for Disease Control and Prevention (CDC) Hand Hygiene Guideline, (2) compare rates of health care-associated infections (HAI) before and after implementation of the Guideline recommendations, and (3) examine the patterns and correlates of changes in rates of HAI. We used pre- and post-Guideline implementation site visits and surveys in the setting of 40 US hospitals—members of the National Nosocomial Infections Surveillance System—and measured HAI rates 1 year before and after publication of the CDC Guideline and used direct observation of hand hygiene compliance and Guideline implementation scores. Results All study hospitals had changed their policies and procedures and provided products in compliance with Guideline recommendations; 89.8% of 1359 staff members surveyed anonymously reported that they were familiar with the Guideline. However, in 44.2% of the hospitals (19/40), there was no evidence of a multidisciplinary program to improve compliance. Hand hygiene rates remained low (mean, 56.6%). Rates of central line-associated bloodstream infections were significantly lower in hospitals with higher rates of hand hygiene (P < .001). No impact of Guideline implementation or hand hygiene compliance on other HAI rates was identified. Other factors occurring over time could affect rates of HAI. Observed hand hygiene compliance rates were likely to overestimate rates in actual practice. The study may have been of too short duration to detect the impact of a practice guideline. Conclusion Wide dissemination of this Guideline was not sufficient to change practice. Only some hospitals had initiated multidisciplinary programs; practice change is unlikely without such multidisciplinary efforts and explicit administrative support. PMID:18063132

2017-07-18

Cancer-related fatigue (CRF) is a key concern for people living with cancer and can impair physical functioning and activities of daily living. Evidence-based guidelines for CRF are available, yet inconsistently implemented globally. This study aimed to identify barriers and enablers to applying a cancer fatigue guideline and to derive implementation strategies. A mixed-method study explored the feasibility of implementing the CRF guideline developed by the Canadian Association for Psychosocial Oncology (CAPO). Health professionals, managers and consumers from different practice settings participated in a modified Delphi study with two survey rounds. A reference group informed the design of the study including the surveys. The first round focused on guideline characteristics, compatibility with current practice and experience, and behaviour change. The second survey built upon and triangulated the first round. Forty-five health practitioners and managers, and 68 cancer survivors completed the surveys. More than 75% of participants endorsed the CAPO cancer related fatigue guidelines. Some respondents perceived a lack of resources for accessible and expert fatigue management services. Further barriers to guideline implementation included complexity, limited practical details for some elements, and lack of clinical tools such as assessment tools or patient education materials. Recommendations to enhance guideline applicability centred around four main themes: (1) balancing the level of detail in the CAPO guideline with ease of use, (2) defining roles of different professional disciplines in CRF management, (3) how best to integrate CRF management into policy and practice, (4) how best to ensure a consumer-focused approach to CRF management. Translating current knowledge on optimal management of CRF into clinical practice can be enhanced by the adoption of valid guidelines. This study indicates that it is feasible to adopt the CAPO guidelines. Clinical application may be further enhanced with guideline adaptation, professional education and integration with existing practices.

ABSTRACT Good guidelines will help us to take evidence into practice. In a survey among Dutch orthopedic surgeons, development and use of evidence-based guidelines was perceived as one of the best ways of moving from opinion-based to evidence-based orthopedic practice. The increasing number of guidelines means that knowing how to make a critical appraisal of guidelines is now a key part of every surgeon’s life. This is particularly true because guidelines use varying systems to judge the quality of evidence and the strength of recommendations. In this manuscript we discuss what a guideline is, where we can find guidelines, how to evaluate the quality of guidelines, and finally provide an example on the different steps of guideline development. Thus, we show that good guidelines are a summary of the best available evidence and that they provide a graded recommendation to help surgeons in evidence-based practice. PMID:19234892

To identify the characteristics of the published clinical practice guidelines for the management of epithelial ovarian cancer that suggest a good methodological quality. A literature review was performed on 25 clinical practice guidelines for epithelial ovarian cancer that were identified in different databases (MEDLINE, Guidelines International Network, National Guidelines Clearing house) published between 2007 and 2014. The quality of the guidelines was evaluated using the Appraisal of Guidelines Research and Evaluation II tool. Descriptive and bivariate analyses were performed to assess the association between the quality of the guidelines and of some of their features and their developers. Just under half (48%) of the guidelines were rated as low quality. Scientific societies or independent centres and private funding, or under-reporting the source of funding, were statistically associated with lower quality of clinical practice guidelines (P<.01). The guidelines developed by National Program Guidelines had a median of consistently higher scores in all domains of the Appraisal of Guidelines Research and Evaluation II, with significant differences in the definition of scope and objectives, the participation of stakeholders, the methodological rigour of development, and applicability to the context. Features such as the nature of the developer and funding of the guidelines are predictors of quality that should be taken into account prior to the use of the recommendations of a document.

The quality of reporting practice guidelines is often poor, and there is no widely accepted guidance or standards for such reporting in health care. The international RIGHT (Reporting Items for practice Guidelines in HealThcare) Working Group was established to address this gap. The group followed an existing framework for developing guidelines for health research reporting and the EQUATOR (Enhancing the QUAlity and Transparency Of health Research) Network approach. It developed a checklist and an explanation and elaboration statement. The RIGHT checklist includes 22 items that are considered essential for good reporting of practice guidelines: basic information (items 1 to 4), background (items 5 to 9), evidence (items 10 to 12), recommendations (items 13 to 15), review and quality assurance (items 16 and 17), funding and declaration and management of interests (items 18 and 19), and other information (items 20 to 22). The RIGHT checklist can assist developers in reporting guidelines, support journal editors and peer reviewers when considering guideline reports, and help health care practitioners understand and implement a guideline.

Adherence to clinical guidelines requires support in practice. However, systematic implementation of evidence-based guidelines is not common practice in oral healthcare. The Knowledge Institute Oral Care (KiMo) offers the opportunity to take into account potential barriers and facilitators during the development of evidence-based clinical practice guidelines. These factors which are relevant to the guideline and the oral healthcare practice provide the ingredients for a tailor-made programme of implementation that has a scientific basis. Elements of any implementation programme are the quality indicators derived from the oral healthcare guidelines. These indicators should fit, on the one hand, the specific goals of the guidelines (patient safety, effectiveness, efficiency, patient-centred, timeliness, accessibility) and, onthe other hand, the various perspectives of the different stakeholders, such as patients, caregivers, health insurers and inspectorate. These quality indicators provide information on adherence to the guidelines, the results of a certain treatment and the success of the implementation strategy, all with the aim to improve the quality of oral healthcare.

Clinical practice guidelines are of increasing importance in the decision making for the treatment of knee osteoarthritis. Inconsistent recommendations regarding the use of intra-articular hyaluronic acid for the treatment of knee osteoarthritis have led to confusion among treating physicians. Literature search to identify clinical practice guidelines that provide recommendations regarding the use of intra-articular hyaluronic acid treatment for knee osteoarthritis was conducted. Included guidelines were appraised using the AGREE II instrument. Guideline development methodologies, how the results were assessed, the recommendation formation, and work group composition were summarized. Overall, 10 clinical practice guidelines were identified that met our inclusion criteria. AGREE II domain scores were variable across the included guidelines. The methodology utilized across the guidelines was heterogeneous regarding the evidence inclusion criteria, analysis of evidence results, formulation of clinical practice recommendations, and work group composition. The recommendations provided by the guidelines for intra-articular hyaluronic acid treatment for knee osteoarthritis are highly inconsistent as a result of the variability in guideline methodology. Overall, 30% of the included guidelines recommended against the use of intra-articular hyaluronic acid in the treatment of knee osteoarthritis, while 30% deemed the treatment an appropriate intervention under certain scenarios. The remaining 40% of the guidelines provided either an uncertain recommendation or no recommendation at all, based on the high variability in reviewed evidence regarding efficacy and trial quality. There is a need for a standard "appropriate methodology" that is agreed upon for osteoarthritis clinical practice guidelines in order to prevent the development of conflicting recommendations for intra-articular hyaluronic acid treatment for knee osteoarthritis, and to assure that treating physicians who are utilizing these guidelines are making their clinical decisions on the best available evidence. At present, the inconsistent recommendations provided for intra-articular hyaluronic acid treatment make it difficult for clinical professionals to determine its appropriateness when treating patients with knee osteoarthritis.

Hemodialysis (HD) is a complex procedure with many specifications and requires adherence to a set of particular clinical practice guidelines. These guidelines had already been established by globally acclaimed renal authorities and their implementation was shown to correlate with patients' morbidity and mortality. This study was conducted to evaluate the adherence of healthcare professionals to the evidence-based clinical practice patterns in Khartoum State HD units. A cross-sectional study was conducted in Khartoum State HD units during the period from September 2010 to January of 2011. Data was collected from the healthcare professionals using a specially designed checklist. The checklist included the evidence-based clinical practice guidelines for the HD vascular access, HD adequacy, anemia of chronic kidney disease (CKD), nutrition, cardiovascular risk assessment, and hepatitis B and C virus infection control. Implementation of these guidelines was evaluated, and further graded using a Likert-type scale. Four randomly selected HD units were included in the study. The rate of implementation of the HD vascular access guidelines was 54.8%, adequacy guidelines 57%, anemia of CKD 68.8%, nutrition 58.4%, cardiovascular risk assessment 57%, and hepatitis B and C infection control guidelines was 79.2%. Overall, the four HD units assessed showed moderate deviations from the practice guidelines of anemia of CKD and hepatitis B and C infection control. Extreme deviations from the clinical practice guidelines were seen in HD vascular access practices, adequacy assessments, nutrition and cardiovascular risk assessment. Hemodialysis services in Khartoum State are in need of great improvements regarding adherence to protocols and the standards of care.

Transition to adult-centered care is becoming an increasingly important area of practice in pediatric organ transplant. Standardized, best-practice guidelines are needed to assist transplant practitioners in providing optimal transitional care for this population of patients. To describe the development and implementation of a practice guideline for the transitional care of pediatric transplant recipients. A quality improvement project was undertaken in a pediatric multiorgan transplant program setting. Strategies employed included (1) creation of an interdisciplinary working group, (2) survey of transition-related practices and learning needs of transplant practitioners, (3) review of the literature and existing transition-related materials, and (4) creation of transition guidelines. An interdisciplinary survey of transplant practitioners at our institution identified practice strengths related to transitional care and learning needs. Review of relevant literature and other materials revealed limited but emerging research related to the transition of pediatric transplant recipients from pediatric to adult care. Existing transition tools were examined and applicable items identified. A practice guideline for use with pediatric transplant recipients transitioning to adult care was developed. Strategies to educate staff about the guideline and promote ongoing guideline use were implemented. Preparing pediatric transplant recipients and their families for transition to adult-centered care is an emerging challenge for transplant teams. These guidelines provide practitioners with a developmentally sensitive overview of important transition-related domains and strategies directed toward patients and their caregivers, who may experience the process of transition differently. Dissemination of the pediatric transplant transition guideline will make transition information more widely available to transplant practitioners.

Chiropractic quality assurance: standards and guidelines

Gatterman, Meridel I; Dobson, Thomas P; LeFevbre, Ron

2001-01-01

Chiropractic quality assurance involves development of both clinical guidelines and standards. Confusion generated by poor differentiation of guidelines from standards contributes to mistrust of the guideline development process. Guidelines are considered to be recommendations that allow for flexibility and individual patient differences. Standards are more binding and require a high level of supporting evidence. While guidelines serve as educational tools to improve the quality of practice, standards that outline minimum competency are used more as administrative tools on which to base policy. Barriers to development of clinical guidelines and standards include fear that they will create prescriptive “cookbook” practice, and the distrust that guidelines are developed primarily for cost containment. Clinicians also criticize guidelines developed by academics that don't relate to practice, and those based on evidence that lacks clinical relevance. Conflicting guidelines perceived to be based on strong bias or conflict of interest are also suspect. To reduce barriers to acceptance and implementation, guidelines should be inclusive, patient-centered, and based on a variety of evidence and clinical experience.

Guidelines were introduced in hospital- and practice-based otorhinolaryngology in the 1990ies, and have been undergoing further development ever since. There are currently 20 guidelines on file at the German Society of Oto-Rhino-Laryngology, Head & Neck Surgery. The society has cooperated in further 34 guidelines. The quality of the guidelines has been continuously improved by concrete specifications put forward by the Association of the Scientific Medical Societies in Germany (Arbeitsgemeinschaft der Wissenschaftlichen Medizinischen Fachgesellschaften e.V., AWMF). Since increasing digitalization has made access to scientific publications quicker and simpler, relevant study results can be incorporated in guidelines more easily today than in the analog world. S2e and S3 guidelines must be based on a formal literature search with subsequent evaluation of the evidence. The consensus procedure for S2k guidelines is also regulated. However, the implementation of guidelines in routine medical practice must still be considered inadequate, and there is still a considerable need for improvement in adherence to these guidelines.

Accessibility of water immersion for labour and/or birth is often dependent on the care provider and also the policies/guidelines that underpin practice. With little high quality research about the safety and practicality of water immersion, particularly for birth, policies/guidelines informing the practice may lack the evidence necessary to ensure practitioner confidence surrounding the option thereby limiting accessibility and women's autonomy. The aims of the study were to determine how water immersion policies and/or guidelines are informed, who interprets the evidence to inform policies/guidelines and to what extent the policy/guideline facilitates the option for labour and birth. Phase one of a three-phase mixed-methods study critically analysed 25 Australian water immersion policies/guidelines using critical discourse analysis. Policies/guidelines pertaining to the practice of water immersion reflect subjective opinions and views of the current literature base in favour of the risk-focused obstetric and biomedical discursive practices. Written with hegemonic influence, policies and guidelines impact on the autonomy of both women and practitioners. Policies and guidelines pertaining to water immersion, particularly for birth reflect opinion and varied interpretations of the current literature base. A degree of hegemonic influence was noted prompting recommendations for future maternity care policy and guidelines'.

2016-12-01

To provide recommended practice guidelines for assessing single operative performances and for combining results of operative performance assessments into estimates of overall operative performance ability. Operative performance is one defining characteristic of surgeons. Assessment of operative performance is needed to provide feedback with learning benefits to surgical residents in training and to assist in making progress decisions for residents. Operative performance assessment has been a focus of investigation over the past 20 years. This review is designed to integrate findings of this research into a set of recommended operative performance practices. Literature from surgery and from other pertinent research areas (psychology, education, business) was reviewed looking for evidence to inform practice guideline development. Guidelines were created along with a conceptual and scientific foundation for each guideline. Ten guidelines are provided for assessing individual operative performances and 10 are provided for combing data from individual operative performances into overall judgments of operative performance ability. The practice guidelines organize available information to be immediately useful to program directors, to support surgical training, and to provide a conceptual framework upon which to build as the base of pertinent knowledge expands through future research and development efforts.

Acute respiratory distress syndrome (ARDS) is a devastating clinical syndrome with a considerable case fatality rate (~30-40%). Health disparities exist with African descent subjects (ADs) exhibiting greater mortality than European descent individuals (EDs). Myosin light chain kinase (MLCK) is encoded by MYLK whose genetic variants are implicated in ARDS pathogenesis and may influence ARDS mortality. As baseline population-specific epigenetic changes, i.e. cytosine modifications, have been observed between AD and ED individuals, epigenetic variations in MYLK may provide insights into ARDS disparities. We compared methylation levels of MYLK CpGs between ARDS patients and ICU controls overall and by ethnicity in a nested case control study of 39 ARDS cases and 75 non-ARDS intensive care unit controls. Two MYLK CpG sites (cg03892735, cg23344121) were differentially modified between ARDS subjects and controls (p<0.05; q<0.25) in a logistic regression model, where no effect modification from ethnicity or age was found. One CpG site was associated with ARDS in patients less than 58 years old, cg19611163 (intron 19,20). Two CpG sites were associated with ARDS in EDs only, gene body CpG (cg01894985, intron 2,3) and CpG (cg16212219, intron 31,32), with higher modification levels exhibited in ARDS subjects than controls. Cis-acting mQTL (modified cytosine quantitative trait loci) were identified using linear regression between local genetic variants and modification levels for two ARDS-associated CpGs (cg23344121, cg16212219). In summary, these ARDS-associated MYLK CpGs with effect modification by ethnicity and local mQTL, suggest that MYLK epigenetic variation and local genetic background may contribute to health disparities observed in ARDS.

Cardiac rhythm management devices provide therapies for both arrhythmias and resynchronisation but not heart failure, which affects millions of patients worldwide. This paper reviews recent advances in biophysics and mathematical engineering that provide a novel technological platform for addressing heart disease and enabling beat-to-beat adaptation of cardiac pacing in response to physiological feedback. The technology consists of silicon hardware central pattern generators (hCPGs) that may be trained to emulate accurately the dynamical response of biological central pattern generators (bCPGs). We discuss the limitations of present CPGs and appraise the advantages of analog over digital circuits for application in bioelectronic medicine. To test the system, we have focused on the cardio-respiratory oscillators in the medulla oblongata that modulate heart rate in phase with respiration to induce respiratory sinus arrhythmia (RSA). We describe here a novel, scalable hCPG comprising physiologically realistic (Hodgkin–Huxley type) neurones and synapses. Our hCPG comprises two neurones that antagonise each other to provide rhythmic motor drive to the vagus nerve to slow the heart. We show how recent advances in modelling allow the motor output to adapt to physiological feedback such as respiration. In rats, we report on the restoration of RSA using an hCPG that receives diaphragmatic electromyography input and use it to stimulate the vagus nerve at specific time points of the respiratory cycle to slow the heart rate. We have validated the adaptation of stimulation to alterations in respiratory rate. We demonstrate that the hCPG is tuneable in terms of the depth and timing of the RSA relative to respiratory phase. These pioneering studies will now permit an analysis of the physiological role of RSA as well as its any potential therapeutic use in cardiac disease. PMID:25433077

Background The link between DNA methylation, obesity, and adiposity-related diseases in the general population remains uncertain. Methods and Findings We conducted an association study of body mass index (BMI) and differential methylation for over 400,000 CpGs assayed by microarray in whole-blood-derived DNA from 3,743 participants in the Framingham Heart Study and the Lothian Birth Cohorts, with independent replication in three external cohorts of 4,055 participants. We examined variations in whole blood gene expression and conducted Mendelian randomization analyses to investigate the functional and clinical relevance of the findings. We identified novel and previously reported BMI-related differential methylation at 83 CpGs that replicated across cohorts; BMI-related differential methylation was associated with concurrent changes in the expression of genes in lipid metabolism pathways. Genetic instrumental variable analysis of alterations in methylation at one of the 83 replicated CpGs, cg11024682 (intronic to sterol regulatory element binding transcription factor 1 [SREBF1]), demonstrated links to BMI, adiposity-related traits, and coronary artery disease. Independent genetic instruments for expression of SREBF1 supported the findings linking methylation to adiposity and cardiometabolic disease. Methylation at a substantial proportion (16 of 83) of the identified loci was found to be secondary to differences in BMI. However, the cross-sectional nature of the data limits definitive causal determination. Conclusions We present robust associations of BMI with differential DNA methylation at numerous loci in blood cells. BMI-related DNA methylation and gene expression provide mechanistic insights into the relationship between DNA methylation, obesity, and adiposity-related diseases. PMID:28095459

The crustacean pyloric Central Pattern Generator (CPG) is a nervous circuit that endogenously provides periodic motor patterns. Even after about 40 years of intensive studies, the rhythm genesis is still not rigorously understood in this CPG, mainly because it is made of neurons with irregular intrinsic activity. Using mathematical models we addressed the question of using a network of irregularly behaving elements to generate periodic oscillations, and we show some advantages of using non-periodic neurons with intrinsic behavior in the transition from bursting to tonic spiking (as found in biological pyloric CPGs) as building components. We studied two- and three-neuron model CPGs built either with Hindmarsh-Rose or with conductance-based Hodgkin-Huxley-like model neurons. By changing a model's parameter we could span the neuron's intrinsic dynamical behavior from slow periodic bursting to fast tonic spiking, passing through a transition where irregular bursting was observed. Two-neuron CPG, half center oscillator (HCO), was obtained for each intrinsic behavior of the neurons by coupling them with mutual symmetric synaptic inhibition. Most of these HCOs presented regular antiphasic bursting activity and the changes of the bursting frequencies was studied as a function of the inhibitory synaptic strength. Among all HCOs, those made of intrinsic irregular neurons presented a wider burst frequency range while keeping a reliable regular oscillatory (bursting) behavior. HCOs of periodic neurons tended to be either hard to change their behavior with synaptic strength variations (slow periodic burster neurons) or unable to perform a physiologically meaningful rhythm (fast tonic spiking neurons). Moreover, 3-neuron CPGs with connectivity and output similar to those of the pyloric CPG presented the same results.

Fast Dynamical Coupling Enhances Frequency Adaptation of Oscillators for Robotic Locomotion Control

2017-01-01

Rhythmic neural signals serve as basis of many brain processes, in particular of locomotion control and generation of rhythmic movements. It has been found that specific neural circuits, named central pattern generators (CPGs), are able to autonomously produce such rhythmic activities. In order to tune, shape and coordinate the produced rhythmic activity, CPGs require sensory feedback, i.e., external signals. Nonlinear oscillators are a standard model of CPGs and are used in various robotic applications. A special class of nonlinear oscillators are adaptive frequency oscillators (AFOs). AFOs are able to adapt their frequency toward the frequency of an external periodic signal and to keep this learned frequency once the external signal vanishes. AFOs have been successfully used, for instance, for resonant tuning of robotic locomotion control. However, the choice of parameters for a standard AFO is characterized by a trade-off between the speed of the adaptation and its precision and, additionally, is strongly dependent on the range of frequencies the AFO is confronted with. As a result, AFOs are typically tuned such that they require a comparably long time for their adaptation. To overcome the problem, here, we improve the standard AFO by introducing a novel adaptation mechanism based on dynamical coupling strengths. The dynamical adaptation mechanism enhances both the speed and precision of the frequency adaptation. In contrast to standard AFOs, in this system, the interplay of dynamics on short and long time scales enables fast as well as precise adaptation of the oscillator for a wide range of frequencies. Amongst others, a very natural implementation of this mechanism is in terms of neural networks. The proposed system enables robotic applications which require fast retuning of locomotion control in order to react to environmental changes or conditions. PMID:28377710

Epigenomes are tissue specific and thus the choice of surrogate tissue can play a critical role in interpreting neonatal epigenome-wide association studies (EWAS) and in their extrapolation to target tissue. To develop a better understanding of the link between tissue specificity and neonatal EWAS, and the contributions of genotype and prenatal factors, we compared genome-wide DNA methylation of cord tissue and cord blood, two of the most accessible surrogate tissues at birth. In 295 neonates, DNA methylation was profiled using Infinium HumanMethylation450 beadchip arrays. Sites of inter-individual variability in DNA methylation were mapped and compared across the two surrogate tissues at birth, i.e., cord tissue and cord blood. To ascertain the similarity to target tissues, DNA methylation profiles of surrogate tissues were compared to 25 primary tissues/cell types mapped under the Epigenome Roadmap project. Tissue-specific influences of genotype on the variable CpGs were also analyzed. Finally, to interrogate the impact of the in utero environment, EWAS on 45 prenatal factors were performed and compared across the surrogate tissues. Neonatal EWAS results were tissue specific. In comparison to cord blood, cord tissue showed higher inter-individual variability in the epigenome, with a lower proportion of CpGs influenced by genotype. Both neonatal tissues were good surrogates for target tissues of mesodermal origin. They also showed distinct phenotypic associations, with effect sizes of the overlapping CpGs being in the same order of magnitude. The inter-relationship between genetics, prenatal factors and epigenetics is tissue specific, and requires careful consideration in designing and interpreting future neonatal EWAS. This birth cohort is a prospective observational study, designed to study the developmental origins of health and disease, and was retrospectively registered on 1 July 2010 under the identifier NCT01174875 .

Critical Appraisal Tools and Reporting Guidelines for Evidence-Based Practice.

Buccheri, Robin K; Sharifi, Claire

2017-12-01

Nurses engaged in evidence-based practice (EBP) have two important sets of tools: Critical appraisal tools and reporting guidelines. Critical appraisal tools facilitate the appraisal process and guide a consumer of evidence through an objective, analytical, evaluation process. Reporting guidelines, checklists of items that should be included in a publication or report, ensure that the project or guidelines are reported on with clarity, completeness, and transparency. The primary purpose of this paper is to help nurses understand the difference between critical appraisal tools and reporting guidelines. A secondary purpose is to help nurses locate the appropriate tool for the appraisal or reporting of evidence. A systematic search was conducted to find commonly used critical appraisal tools and reporting guidelines for EBP in nursing. This article serves as a resource to help nurse navigate the often-overwhelming terrain of critical appraisal tools and reporting guidelines, and will help both novice and experienced consumers of evidence more easily select the appropriate tool(s) to use for critical appraisal and reporting of evidence. Having the skills to select the appropriate tool or guideline is an essential part of meeting EBP competencies for both practicing registered nurses and advanced practice nurses (Melnyk & Gallagher-Ford, 2015; Melnyk, Gallagher-Ford, & Fineout-Overholt, 2017). Nine commonly used critical appraisal tools and eight reporting guidelines were found and are described in this manuscript. Specific steps for selecting an appropriate tool as well as examples of each tool's use in a publication are provided. Practicing registered nurses and advance practice nurses must be able to critically appraise and disseminate evidence in order to meet EBP competencies. This article is a resource for understanding the difference between critical appraisal tools and reporting guidelines, and identifying and accessing appropriate tools or guidelines. © 2017 Sigma Theta Tau International.

Potential facilitators and barriers to adopting standard treatment guidelines in clinical practice.

Sharma, Sangeeta; Pandit, Ajay; Tabassum, Fauzia

2017-04-18

Purpose The purpose of this paper is to assess medicines information sources accessed by clinicians, if sources differed in theory and practice and to find out the barriers and facilitators to effective guideline adoption. Design/methodology/approach In all, 183 doctors were surveyed. Barriers and facilitators were classified as: communication; potential adopters; innovation; organization characteristics and environmental/social/economic context. Findings Most of the clinicians accessed multiple information sources including standard treatment guidelines, but also consulted seniors/colleagues in practice. The top three factors influencing clinical practice guideline adoption were innovation characteristics, environmental context and individual characteristics. The respondents differed in the following areas: concerns about flexibility offered by the guideline; denying patients' individuality; professional autonomy; insights into gaps in current practice and evidence-based practice; changing practices with little or no benefit. Barriers included negative staff attitudes/beliefs, guideline integration into organizational structures/processes, time/resource constraints. Fearing third parties (government and insurance companies) restricting medicines reimbursement and poor liability protection offered by the guidelines emerged as the barriers. Facilitators include aligning organizational structures/processes with the innovation; providing leadership support to guide diffusion; increasing awareness and enabling early innovation during pre/in-service training, with regular feedback on outcomes and use. Practical implications Guideline adoption in clinical practice is partly within doctors' control. There are other key prevailing factors in the local context such as environmental, social context, professional and organizational culture affecting its adoption. Organizational policy and accreditation standards necessitating adherence can serve as a driver. Originality/value This survey among clinicians, despite limitations, gives helpful insights. While favourable attitudes may be helpful, clinical adoption could be improved more effectively by targeting barriers.

Strehl ratio: a tool for optimizing optical nulls and singularities.

Hénault, François

2015-07-01

In this paper a set of radial and azimuthal phase functions are reviewed that have a null Strehl ratio, which is equivalent to generating a central extinction in the image plane of an optical system. The study is conducted in the framework of Fraunhofer scalar diffraction, and is oriented toward practical cases where optical nulls or singularities are produced by deformable mirrors or phase plates. The identified solutions reveal unexpected links with the zeros of type-J Bessel functions of integer order. They include linear azimuthal phase ramps giving birth to an optical vortex, azimuthally modulated phase functions, and circular phase gratings (CPGs). It is found in particular that the CPG radiometric efficiency could be significantly improved by the null Strehl ratio condition. Simple design rules for rescaling and combining the different phase functions are also defined. Finally, the described analytical solutions could also serve as starting points for an automated searching software tool.

Clinical practice guidelines for gynecologic cancers have been developed by many organizations. Although these guidelines have much in common in terms of the practice of standard of care for uterine corpus cancer, practice guidelines that reflect the characteristics of patients and healthcare and insurance systems are needed for each country. The Korean Society of Gynecologic Oncology (KSGO) published the first edition of practice guidelines for gynecologic cancer treatment in late 2006; the second edition was released in July 2010 as an evidence-based recommendation. The Guidelines Revision Committee was established in 2015 and decided to produce the third edition of the guidelines as an advanced form based on evidence-based medicine, considering up-to-date clinical trials and abundant qualified Korean data. These guidelines cover screening, surgery, adjuvant treatment, and advanced and recurrent disease with respect to endometrial carcinoma and uterine sarcoma. The committee members and many gynecologic oncologists derived key questions from the discussion, and a number of relevant scientific literatures were reviewed in advance. Recommendations for each specific question were developed by the consensus conference, and they are summarized here, together with other details. The objective of these practice guidelines is to establish standard policies on issues in clinical areas related to the management of uterine corpus cancer based on the findings in published papers to date and the consensus of experts as a KSGO Consensus Statement.

The applicability assessment based on questionnaire survey and the traditional Chinese medicine (TCM) practitioners were asked to independently fill the Questionnaire for Applicability Assessment on the Guidelines for Diagnosis and Treatment in Traditional Chinese Medicine. The practicability assessment was based on prospective case investigation and analysis method and the TCM practitioners-in-charge filled the Case Investigation Questionnaire for Practicability Assessment on the Guidelines for Diagnosis and Treatment in Traditional Chinese Medicine. The data were analyzed in descriptive statistics. 151 questionnaires were investigated for applicability assessment and 1 016 patients were included for practicability assessment. The results showed that 88.74% of them were familiar with the guidelines and 45.70% used them. The guidelines quality and related items were similar in applicability assessment and practicability assessment, and scored highly as more than 85.00% except the "recuperating and prevention". The results suggested that the quality of Guidelines for Diagnosis and Treatment of Common Diseases of Otolaryngology in Traditional Chinese Medicine was high and could better guide the clinical practice. The "recuperating and prevention" part should be improved and the evidence data should be included in future guideline revision, so that the clinical utilization rate could be increased.

Colombia is developing multiple national practice guidelines from a range of diseases. Clinical practice guidelines represent a very useful tool to be able to take decision over a patient care that is widely available for the clinician. In psychiatry there are a good number of international clinical guidelines for the treatment of schizophrenia nevertheless there is no article that evaluate them scientifically In the settings of developing a Colombian schizophrenia practice guideline, a systematic search was performed in multiple databases and the results were then evaluated by two trained persons. We present the results globally and by domains. We found 164 matches for possible guidelines. After screening 7 guidelines were evaluated with the AGREE II instrument. Globally and by the different domains, the National Institute for Health and Care Excellence (NICE) was the guideline that got the best score. From the guidelines that were reviewed, 4 were from Europe and only 2 were from Latin America. None of the guidelines used GRADE methodology for the recommendations. The diversity of the schizophrenia treatment guidelines does not allow an easy adoption of the recommendation by a psychiatrist in Colombia. Copyright © 2014 Asociación Colombiana de Psiquiatría.

It is well documented that financial conflicts of interest influence medical research and clinical practice. Prior to the Open Payments provisions of the Affordable Care Act, financial ties became apparent only through self-disclosure. The nature of financial interests has not been studied among physicians who develop dermatology clinical practice guidelines. To evaluate payments received by physicians who author dermatology clinical practice guidelines, compare disclosure statements for accuracy, determine whether pharmaceutical companies from which the authors received payments manufactured products related to the guidelines, and examine the extent to which the American Academy of Dermatology enforced their Administrative Regulations for guideline development. Three American Academy of Dermatology guidelines published from 2013 to 2016 were retrieved. Double data extraction was used to record financial payments received by 49 guideline authors using the Open Payments database. Payments received by the authors from the date of the initial literature search to the date of publication were used to evaluate disclosure statement accuracy, detail the companies providing payments, and evaluate Administrative Regulations enforcement. This study is applicable to clinical practice guideline panels drafting recommendations, physicians using clinical practice guidelines to inform patient care, and those establishing policies for guideline development. Our main outcomes are the monetary values and types of payments received by physicians who author dermatology guidelines and the accuracy of disclosure statements. Data were collected from the Open Payments database and analyzed descriptively. Of the 49 authors evaluated, 40 received at least 1 reported industry payment, 31 accepted more than $1000, 25 accepted more than $10 000, and 18 accepted more than $50 000. Financial payments amounted to a mean of $157 177 per author. The total reimbursement among the 49 authors from 2013 to 2015 was $7 701 681. Of the 40 authors receiving payments, 22 did not accurately disclose industry relationships. Authors received payments from companies with products directly related to the guideline topic. Violations to the Administrative Regulations were found. Dermatology clinical practice guideline authors received sizable industry payments and did not completely disclose these payments. The American Academy of Dermatology policies may benefit from stricter enforcement or the adoption of new standards.

OBJECTIVE: To assess Canadian physicians' confidence in, attitudes about and preferences regarding clinical practice guidelines. DESIGN: Cross-sectional, self-administered mailed survey. PARTICIPANTS: Stratified random sample of 3000 Canadian physicians; 1878 (62.6%) responded. SETTING: Canada. OUTCOME MEASURES: Physicians' use of various information sources; familiarity with and confidence in guidelines; attitudes about guidelines and their effect on medical care; rating of importance of guidelines and other sources of information in clinical decision-making; rating of importance of various considerations in deciding whether to adopt a set of guidelines; and rating of usefulness of different formats for presenting guidelines. MAIN RESULTS: In all, 52% of the respondents reported using guidelines at least monthly, substantially less frequently than traditional information sources. Most of the respondents expressed confidence in guidelines issued by various physician organizations, but 51% to 77% were not confident in guidelines issued by federal or provincial health ministries or by health insurance plans. The respondents were generally positive about guidelines (e.g., over 50% strongly agreed that they are a convenient source of advice and good educational tools); however, 22% to 26% had concerns about loss of autonomy, the rigidity of guidelines and decreased satisfaction with medical practice. Endorsement by respected colleagues or major organizations was identified as very important by 78% and 62% of the respondents respectively in deciding whether to adopt a set of guidelines in their practice. User friendliness of the guidelines format was thought to be very important by 62%; short pamphlets, manuals summarizing a number of guidelines, journal articles and pocket cards summarizing guidelines were the preferred formats (identified as most useful by 50% to 62% of the respondents). CONCLUSIONS: Canadian physicians, although generally positive about guidelines and confident in those developed by clinicians, have not yet integrated the use of guidelines into their practices to a large extent. Our results suggest that respected organizations and opinion leaders should be involved in the development of guidelines and that the acceptability of any proposed format and medium for guidelines presentation should be pretested.

Antoniotti, Nina; Bernard, Jordana

2013-01-01

Abstract Background: The American Telemedicine Association (ATA) Standards and Guidelines Committee develops practice standards and guidelines. Key to the Committee's mission is dissemination so the standards can be used in the practice of telemedicine. Over a 2-year period, when a standards document was accessed from the ATA Web site, a short survey was completed, but it did not assess how the documents were used once downloaded. A more formal survey was conducted to determine the impact ATA standards and guidelines are having on healthcare delivery via telemedicine. Materials and Methods: A survey was developed and distributed via SurveyMonkey to 13,177 ATA members and nonmembers in November 2011. Results were compiled and analyzed after a 90-day open period for responses to be submitted. Results: The majority of respondents (96%) believe the practice of telemedicine/telehealth should have standards and guidelines and that the ATA and other professional societies/associations should be responsible for developing them. The top uses of guidelines include guidance for clinical practice, training, gaining reimbursement, and research. Respondents indicating a need for standards and guidelines said the ATA (78.7%) and other professional societies/associations (74.5%) should be responsible for development. When asked to list specific practice guidelines or standards they are using for telehealth, the majority (21.5%) are using in-house (e.g., hospital, company)-developed guidelines, followed by those from professional associations/societies (20.4%) and those developed by the ATA (18.2%). Conclusions: Overall, the survey results indicate guidelines documents developed by the ATA and other professional societies and those developed in-house are being regularly accessed and used in both public and private sectors. Practitioners of telemedicine believe that standards and guidelines are needed for guidance for clinical practice, training, gaining reimbursement, and research, and they are to use those developed by professional organization such as the ATA as well as those developed by their own institutions.

We examined genetic and epigenetic changes that occur during disease progression from indolent to aggressive forms of chronic lymphocytic leukemia (CLL) using serial samples from 27 patients. Analysis of DNA mutations grouped the leukemia cases into three categories: evolving (26%), expanding (26%) and static (47%). Thus, approximately three-quarters of the CLL cases had little to no genetic subclonal evolution. However, we identified significant recurrent DNA methylation changes during progression at 4752 CpGs enriched for regions near Polycomb 2 repressive complex (PRC2) targets. Progression-associated CpGs near the PRC2 targets undergo methylation changes in the same direction during disease progression as during normal development from naive to memory B cells. Our study shows that CLL progression does not typically occur via subclonal evolution, but that certain CpG sites undergo recurrent methylation changes. Our results suggest CLL progression may involve developmental processes shared in common with the generation of normal memory B cells.

A simple rule for quadrupedal gait generation determined by leg loading feedback: a modeling study

PubMed Central

Fukuoka, Yasuhiro; Habu, Yasushi; Fukui, Takahiro

2015-01-01

We discovered a specific rule for generating typical quadrupedal gaits (the order of the movement of four legs) through a simulated quadrupedal locomotion, in which unprogrammed gaits (diagonal/lateral sequence walks, left/right-lead canters, and left/right-lead transverse gallops) spontaneously emerged because of leg loading feedbacks to the CPGs hard-wired to produce a default trot. Additionally, all gaits transitioned according to speed, as seen in animals. We have therefore hypothesized that various gaits derive from a trot because of posture control through leg loading feedback. The body tilt on the two support legs of each diagonal pair during trotting was classified into three types (level, tilted up, or tilted down) according to speed. The load difference between the two legs led to the phase difference between their CPGs via the loading feedbacks, resulting in nine gaits (32: three tilts to the power of two diagonal pairs) including the aforementioned.

With increasing interests in oppressed groups, the number of feminist studies in nursing has steadily increased. Despite the increasing number of feminist studies, very few articles have been written to provide practical guidelines for feminist research in nursing. In this article, guidelines for feminist research in nursing are proposed on the basis of 3 previous feminist studies. First, characteristics of feminist research are concisely described. Then, the 3 studies that are the basis for the guidelines are described. Finally, practical guidelines for feminist nursing research are proposed on the basis of 10 idea categories related to issues/concerns from the 3 studies.

In 2011, the Korean Society of Neurogastroenterology and Motility (KSNM) published clinical practice guidelines on the management of irritable bowel syndrome (IBS) based on a systematic review of the literature. The KSNM planned to update the clinical practice guidelines to support primary physicians, reduce the socioeconomic burden of IBS, and reflect advances in the pathophysiology and management of IBS. The present revised version of the guidelines is in continuity with the previous version and targets adults diagnosed with, or suspected to have, IBS. A librarian created a literature search query, and a systematic review was conducted to identify candidate guidelines. Feasible documents were verified based on predetermined inclusion and exclusion criteria. The candidate seed guidelines were fully evaluated by the Guidelines Development Committee using the Appraisal of Guidelines for Research and Evaluation II quality assessment tool. After selecting 7 seed guidelines, the committee prepared evidence summaries to generate data exaction tables. These summaries comprised the 4 main themes of this version of the guidelines: colonoscopy; a diet low in fermentable oligosaccharides, disaccharides, monosaccharides, and polyols; probiotics; and rifaximin. To adopt the core recommendations of the guidelines, the Delphi technique (ie, a panel of experts on IBS) was used. To enhance dissemination of the clinical practice guidelines, a Korean version will be made available, and a food calendar for patients with IBS is produced. PMID:29605976

The quality of reporting practice guidelines is often poor, and there is no widely accepted guidance or standards for such reporting in health care. The international RIGHT (Reporting Items for practice Guidelines in HealThcare) Working Group was established to address this gap. The group followed an existing framework for developing guidelines for health research reporting and the EQUATOR (Enhancing the QUAlity and Transparency Of health Research) Network approach. A checklist and an explanation and elaboration statement were developed. The RIGHT checklist includes 22 items that are considered essential for good reporting of practice guidelines: basic information (items 1 to 4), background (items 5 to 9), evidence (items 10 to 12), recommendations (items 13 to 15), review and quality assurance (items 16 and 17), funding and declaration and management of interests (items 18 and 19), and other information (items 20 to 22). The RIGHT checklist can assist developers in reporting guidelines, support journal editors and peer reviewers when considering guideline reports, and help health care practitioners understand and implement a guideline.

Clinical practice guidelines are important evidence-based resources to guide complex clinical decision making. However, it is challenging for health professionals to keep abreast available guidelines and to know how and where to access relevant guidelines. This review examines currently available guidelines for lung cancer published in the English language. Important key features are listed for each identified guideline. The methodology, approaches to dissemination and implementation, and associated resources are summarised. General challenges in the area of guideline development are highlighted. The potential to collaborate more widely across lung cancer guideline developers by sharing literature searches and assessments is discussed. PMID:24163752

Clinical practice guidelines in complementary and alternative medicine. An analysis of opportunities and obstacles. Practice and Policy Guidelines Panel, National Institutes of Health Office of Alternative Medicine.

1997-01-01

An estimated 1 of 3 Americans uses some form of complementary and alternative medicine (CAM), such as acupuncture, homeopathy, or herbal medicine. In 1995, the National Institutes of Health Office of Alternative Medicine convened an expert panel to examine the role of clinical practice guidelines in CAM. The panel concluded that CAM practices currently are unsuitable for the development of evidence-based practice guidelines, in part because of the lack of relevant outcomes data from well-designed clinical trials. Moreover, the notions of standardization and appropriateness, inherent in guideline development, face challenging methodologic problems when applied to CAM, which considers many different treatment practices appropriate and encourages highly individualized care. Due to different belief systems and divergent theories about the nature of health and illness, CAM disciplines have fundamental differences in how they define target conditions, causes of disease, interventions, and outcome measures of effectiveness. These differences are even more striking when compared with those used by Western medicine. The panel made a series of recommendations on strategies to strengthen the evidence base for future guideline development in CAM and to meet better the current information needs of clinicians, patients, and guideline developers who seek information about CAM treatments.

To explore how clinical practice guidelines can be adapted to facilitate shared decision making. This was a qualitative key-informant study with group discussions and semi-structured interviews. First, 75 experts in guideline development or shared decision making participated in group discussions at two international conferences. Next, health professionals known as experts in depression or breast cancer, experts on clinical practice guidelines and/or shared decision making, and patient representatives were interviewed (N=20). Using illustrative treatment decisions on depression or breast cancer, we asked the interviewees to indicate as specifically as they could how guidelines could be used to facilitate shared decision making. Interviewees suggested some generic strategies, namely to include a separate chapter on the importance of shared decision making, to use language that encourages patient involvement, and to develop patient versions of guidelines. Recommendation-specific strategies, related to specific decision points in the guideline, were also suggested: These include structuring the presentation of healthcare options to increase professionals' option awareness; structuring the deliberation process between professionals and patients; and providing relevant patient support tools embedded at important decision points in the guideline. This study resulted in an overview of strategies to adapt clinical practice guidelines to facilitate shared decision making. Some strategies seemed more contentious than others. Future research should assess the feasibility and impact of these strategies to make clinical practice guidelines more conducive to facilitate shared decision making.

Development and validation of an international appraisal instrument for assessing the quality of clinical practice guidelines: the AGREE project.

PubMed

2003-02-01

International interest in clinical practice guidelines has never been greater but many published guidelines do not meet the basic quality requirements. There have been renewed calls for validated criteria to assess the quality of guidelines. To develop and validate an international instrument for assessing the quality of the process and reporting of clinical practice guideline development. The instrument was developed through a multi-staged process of item generation, selection and scaling, field testing, and refinement procedures. 100 guidelines selected from 11 participating countries were evaluated independently by 194 appraisers with the instrument. Following refinement the instrument was further field tested on three guidelines per country by a new set of 70 appraisers. The final version of the instrument contained 23 items grouped into six quality domains with a 4 point Likert scale to score each item (scope and purpose, stakeholder involvement, rigour of development, clarity and presentation, applicability, editorial independence). 95% of appraisers found the instrument useful for assessing guidelines. Reliability was acceptable for most domains (Cronbach's alpha 0.64-0.88). Guidelines produced as part of an established guideline programme had significantly higher scores on editorial independence and, after the publication of a national policy, had significantly higher quality scores on rigour of development (p<0.005). Guidelines with technical documentation had higher scores on that domain (p<0.0001). This is the first time an appraisal instrument for clinical practice guidelines has been developed and tested internationally. The instrument is sensitive to differences in important aspects of guidelines and can be used consistently and easily by a wide range of professionals from different backgrounds. The adoption of common standards should improve the consistency and quality of the reporting of guideline development worldwide and provide a framework to encourage international comparison of clinical practice guidelines.

Patients with hypothyroidism are increasingly enquiring about the benefit of using combination therapy of levothyroxine (LT4) and liothyronine (LT3) as a potential treatment for hypothyroidism. Combination therapy, however, remains controversial. The purpose of this study was to systematically review available hypothyroidism treatment recommendations from clinical practice guidelines from around the world to identify the consensus regarding combination therapy. Clinical practice guidelines were obtained from searches of PubMed, EMBASE, and MEDLINE, using several combinations of MeSH terms. The search was limited to clinical guidelines in English-language publications, published between January 1, 1990 and May 1, 2015. A quantitative approach was utilized for data synthesis. Thirteen guidelines were identified, including three regarding pregnancy, two regarding pediatric populations and eight regarding adult populations. There were six guidelines from North America, four guidelines from Europe and three guidelines from South America. Twelve of the guidelines were published after 2010. Nine guidelines addressed combination therapy of LT4 plus LT3, and all nine concluded that LT4 therapy alone is the standard of care, with insufficient evidence to recommend widespread combination therapy. Only the 2012 ETA Guidelines and the 2015 BTA Guidelines concluded that combination therapy could be used, although only in certain circumstances and as an experimental treatment. This systematic review illustrates that clinical practice guidelines worldwide do not recommend and do not support routine use of combination LT4 and LT3 therapy to treat hypothyroidism.

Cervical cancer screening in adolescents: an evidence-based internet education program for practice improvement among advanced practice nurses.

The literature reports great variation in the knowledge levels and application of the recent changes of cervical cancer screening guidelines into clinical practice. Evidence-based screening guidelines for the prevention and early detection of cervical cancer offers healthcare providers the opportunity to improve practice patterns among female adolescents by decreasing psychological distress as well as reducing healthcare costs and morbidities associated with over-screening. The purpose of this pilot intervention study was to determine the effects of a Web-based continuing education unit (CEU) program on advanced practice nurses' (APNs) knowledge of current cervical cancer screening evidence-based recommendations and their application in practice. This paper presents a process improvement project as an example of a way to disseminate updated evidence-based practice guidelines among busy healthcare providers. This Web-based CEU program was developed, piloted, and evaluated specifically for APNs. The program addressed their knowledge level of cervical cancer and its relationship with high-risk human papillomavirus. It also addressed the new cervical cancer screening guidelines and the application of those guidelines into clinical practice. Results of the study indicated that knowledge gaps exist among APNs about cervical cancer screening in adolescents. However, when provided with a CEU educational intervention, APNs' knowledge levels increased and their self-reported clinical practice behaviors changed in accordance with the new cervical cancer screening guidelines. Providing convenient and readily accessible up-to-date electronic content that provides CEU enhances the adoption of clinical practice guidelines, thereby decreasing the potential of the morbidities associated with over-screening for cervical cancer in adolescents and young women. © 2014 Sigma Theta Tau International.

Practice guidelines have been developed in child neurology during the last fifteen years to address important clinical questions and provide evidence-based recommendations for patient care. This review describes the guideline development process and how it has evolved to meet the needs of child neurologists. Several current child neurology guidelines are reviewed and the advantages and disadvantages of guidelines, as well as the legal consequences of using them to determine a standard of care are discussed. The future of guidelines and of their influence on integrated support systems also is considered. Child neurology practice guidelines are a helpful resource for clinicians, families and institutions as they provide evidence-based recommendations concerning the diagnosis and management of common neurological conditions affecting children. Incorporating consensus processes has allowed expansion of clinically relevant recommendations that has increased the utility of guidelines. Copyright © 2015 Elsevier Inc. All rights reserved.

Value for money in changing clinical practice: should decisions about guidelines and implementation strategies be made sequentially or simultaneously?

2009-01-01

Decisions about clinical practice change, that is, which guidelines to adopt and how to implement them, can be made sequentially or simultaneously. Decision makers adopting a sequential approach first compare the costs and effects of alternative guidelines to select the best set of guideline recommendations for patient management and subsequently examine the implementation costs and effects to choose the best strategy to implement the selected guideline. In an integral approach, decision makers simultaneously decide about the guideline and the implementation strategy on the basis of the overall value for money in changing clinical practice. This article demonstrates that the decision to use a sequential v. an integral approach affects the need for detailed information and the complexity of the decision analytic process. More importantly, it may lead to different choices of guidelines and implementation strategies for clinical practice change. The differences in decision making and decision analysis between the alternative approaches are comprehensively illustrated using 2 hypothetical examples. We argue that, in most cases, an integral approach to deciding about change in clinical practice is preferred, as this provides more efficient use of scarce health-care resources.

Abdominal aortic aneurysm (AAA) is a deadly cardiovascular disease characterised by the gradual, irreversible dilation of the abdominal aorta. AAA is a complex genetic disease but little is known about the role of epigenetics. Our objective was to determine if global DNA methylation and CpG-specific methylation at known AAA risk loci is associated with AAA, and the functional effects of methylation changes. We assessed global methylation in peripheral blood mononuclear cell DNA from 92 individuals with AAA and 93 controls using enzyme-linked immunosorbent assays, identifying hyper-methylation in those with large AAA and a positive linear association with AAA diameter ( P  < 0.0001, R 2  = 0.3175).We then determined CpG methylation status of regulatory regions in genes located at AAA risk loci identified in genome-wide association studies, using bisulphite next-generation sequencing (NGS) in vascular smooth muscle cells (VSMCs) taken from aortic tissues of 44 individuals (24 AAAs and 20 controls). In IL6R , 2 CpGs were hyper-methylated ( P  = 0.0145); in ERG , 13 CpGs were hyper-methylated ( P  = 0.0005); in SERPINB9 , 6 CpGs were hypo-methylated ( P  = 0.0037) and 1 CpG was hyper-methylated ( P  = 0.0098); and in SMYD2 , 4 CpGs were hypo-methylated ( P  = 0.0012).RT-qPCR was performed for each differentially methylated gene on mRNA from the same VSMCs and compared with methylation. This analysis revealed downregulation of SMYD2 and SERPINB9 in AAA, and a direct linear relationship between SMYD2 promoter methylation and SMYD2 expression ( P  = 0.038). Furthermore, downregulation of SMYD2 at the site of aneurysm in the aortic wall was further corroborated in 6 of the same samples used for methylation and gene expression analysis with immunohistochemistry. This study is the first to assess DNA methylation in VSMCs from individuals with AAA using NGS, and provides further evidence there is an epigenetic basis to AAA. Our study shows that methylation status of the SMYD2 promoter may be linked with decreased SMYD2 expression in disease pathobiology. In support of our work, downregulated SMYD2 has previously been associated with adverse cardiovascular physiology and inflammation, which are both hallmarks of AAA. The identification of such adverse epigenetic modifications could potentially contribute towards the development of epigenetic treatment strategies in the future.

Although the BTS-SIGN asthma guideline is one of the most well known and widely respected guidelines in the world, implementation in UK primary care remains patchy. Building on extensive earlier descriptive work, we sought to explore the way teamwork and inter-professional relationships impact on the implementation of the BTS-SIGN guideline on asthma in general practice. Qualitative comparative case study using nine in-depth interviews and 2 focus groups with general practitioners and practice nurses, involved in delivering asthma care. Participants were purposively recruited from practices in a Scottish health board with high and low compliance with the BTS-SIGN asthma guideline. There was a marked difference in the way respondents from practices with high compliance and respondents from practices with low compliance spoke about the value of guidelines and the challenges of implementing them. On both accounts, the former were more positive than the latter and were able to be more specific about the strategies they used to overcome barriers to implementation. We explored the reason for this difference in response and identified practice organisation, centring on delegation of work to nurses, as a factor mediating the practice's level of compliance. Effective delegation was underpinned by organisation of asthma work among practice members who have the appropriate level of skills and knowledge, know and understand each others' work and responsibilities, communicate well among themselves and trust each others' skills. It was the combination of these factors which made for successful delegation and guideline implementation, not any one factor in isolation. In our sample of practices, teamwork and organisation of care within practices appeared to impact on guideline implementation and further larger studies are needed to explore this issue further. Isolated interventions such as measures to improve staff's knowledge or increased clinical resource and time, which are currently being considered, are unlikely to be effective unless practices are supported in developing their teams in a way which supports the deployment of these resources.

Considerable time and resources are allocated to carry out qualitative research. The purpose of our study was to evaluate the availability of qualitative research on women's health screening and assess its influence on screening practice guidelines in the United States, Canada, and the United Kingdom. Medline, CINHAL, and WEB of Science databases were used to identify the availability of qualitative research conducted in the past 15 years on 3 different women's health screening topics: cervical cancer screening, breast cancer screening, and prenatal first-trimester screening. Key national practice guidelines on women's health screening were selected using the National Guideline Clearinghouse web site. Bibliometric analysis was used to determine the frequency of qualitative references cited in the guidelines. A total of 272 qualitative research papers on women's health screening was identified: 109 on cervical cancer screening, 104 on breast cancer screening, and 59 on prenatal first-trimester screening. The qualitative studies focused on health care provider perspectives as well as ethical, ethnographic, psychological, and social issues surrounding screening. Fifteen national clinical practice guidelines on women's health screening were identified. A total of 943 references was cited, only 2 of which comprised of qualitative research cited by only 1 clinical practice guideline. Although there is considerable qualitative research that has been carried out on women's health screening, its incorporation into clinical practice guidelines is minimal. Further exploration of the disconnect between the two is important for enhancing knowledge translation of qualitative research within clinical practice. Copyright © 2014 Mosby, Inc.

Developing clinical practice guidelines: target audiences, identifying topics for guidelines, guideline group composition and functioning and conflicts of interest

PubMed Central

2012-01-01

Clinical practice guidelines are one of the foundations of efforts to improve health care. In 1999, we authored a paper about methods to develop guidelines. Since it was published, the methods of guideline development have progressed both in terms of methods and necessary procedures and the context for guideline development has changed with the emergence of guideline clearing houses and large scale guideline production organisations (such as the UK National Institute for Health and Clinical Excellence). It therefore seems timely to, in a series of three articles, update and extend our earlier paper. In this first paper we discuss: the target audience(s) for guidelines and their use of guidelines; identifying topics for guidelines; guideline group composition (including consumer involvement) and the processes by which guideline groups function and the important procedural issue of managing conflicts of interest in guideline development.

In view of the publication of these guidelines, the scope of this guideline excludes business cases for information, management, and technology projects and large capital projects.

Review of the International Society for Heart and Lung Transplantation Practice guidelines for management of heart failure in children.

PubMed

Colan, Steven D

2015-08-01

In 2004, practice guidelines for the management of heart failure in children by Rosenthal and colleagues were published in conjunction with the International Society for Heart and Lung Transplantation. These guidelines have not been updated or reviewed since that time. In general, there has been considerable controversy as to the utility and purpose of clinical practice guidelines, but there is general recognition that the relentless progress of medicine leads to the progressive irrelevance of clinical practice guidelines that do not undergo periodic review and updating. Paediatrics and paediatric cardiology, in particular, have had comparatively minimal participation in the clinical practice guidelines realm. As a result, most clinical practice guidelines either specifically exclude paediatrics from consideration, as has been the case for the guidelines related to cardiac failure in adults, or else involve clinical practice guidelines committees that include one or two paediatric cardiologists and produce guidelines that cannot reasonably be considered a consensus paediatric opinion. These circumstances raise a legitimate question as to whether the International Society for Heart and Lung Transplantation paediatric heart failure guidelines should be re-reviewed. The time, effort, and expense involved in producing clinical practice guidelines should be considered before recommending an update to the International Society for Heart and Lung Transplantation Paediatric Heart Failure guidelines. There are specific areas of rapid change in the evaluation and management of heart failure in children that are undoubtedly worthy of updating. These domains include areas such as use of serum and imaging biomarkers, wearable and implantable monitoring devices, and acute heart failure management and mechanical circulatory support. At the time the International Society for Heart and Lung Transplantation guidelines were published, echocardiographic tissue Doppler, 3 dimensional imaging, and strain and strain rate were either novel or non-existent and have now moved into the main stream. Cardiac magnetic resonance imaging (MRI) had very limited availability, and since that time imaging and assessment of myocardial iron content, delayed gadolinium enhancement, and extracellular volume have moved into the mainstream. The only devices discussed in the International Society for Heart and Lung Transplantation guidelines were extracorporeal membrane oxygenators, pacemakers, and defibrillators. Since that time, ventricular assist devices have become mainstream. Despite the relative lack of randomised controlled trials in paediatric heart failure, advances continue to occur. These advances warrant implementation of an update and review process, something that is best done under the auspices of the national and international cardiology societies. A joint activity that includes the International Society for Heart and Lung Transplantation, American College of Cardiology/American Heart Association, the Association for European Paediatric and Congenital Cardiology (AEPC), European Society of Cardiology, Canadian Cardiovascular Society, and others will have more credibility than independent efforts by any of these organisations.

Global perspectives on ensuring the safety of pharmaceutical products in the distribution process

The distribution of counterfeit or falsified drugs is increasing worldwide. This can contribute to the high burden of disease and cost to society and is of global concern with the worldwide circulation of pharmaceuticals. The preparation and implementation of good distribution practice should be one of the most important aspects of ensuring safe drug circulation and administration. This research aimed to compare and analyze good distribution practice guidelines from advanced countries and international organizations, and to evaluate the status of the current good distribution practice guidelines in the world. Advanced pharmaceutical countries and international organizations, such as the World Health Organization, European Union, Pharmaceutical Inspection Co-operation Scheme, United States of America, Canada, and Australia, which have stable good distribution practice guidelines and public confidence, were included in the analysis. The World Health Organization and European Union guidelines are models for standardized good distribution practice for nations worldwide. The United States of America has a combination of four different series of distribution practices which have a unique structure and detailed content compared to those of other countries. The Canadian guidelines focus on temperature control during storage and transportation. The Australian guidelines apply to both classes of medicinal products and medical devices and need separate standardization. Transparent information about the Internet chain, international cooperation regarding counterfeiting, a high-standard qualification of sellers and customers, and technology to track and trace the whole life cycle of drugs should be the main focus of future good distribution practice guidelines worldwide.

To describe oncology nurses' use of National Comprehensive Cancer Network (NCCN) clinical practice guidelines for chemotherapy-induced neutropenia (CIN) and febrile neutropenia (FN). Cross-sectional survey design; descriptive, correlational analysis. E-mail invitation to Web-based survey. Random sample of 309 Oncology Nursing Society (ONS) members with e-mail addresses who provide care to adult patients receiving chemotherapy. The investigator-developed Neutropenia Oncology Nurses Survey was used. Descriptive tests compared respondents' personal and professional characteristics to those of general ONS members; nonparametric chi-square and Kruskal-Wallis tests were used to correlate respondents' survey subscale scores with demographic data. Significant associations were entered into multiple logistic regression models. The Neutropenia Oncology Nurses Survey's subscales measured subjective norm, attitude, perceived competence and confidence, perceived barriers, and use of NCCN clinical practice guidelines for CIN and FN. Response rate of nurses who opened the survey was 50%. Most practiced in community versus academic centers. Eighty percent reported using the NCCN clinical practice guidelines for CIN and FN. Respondents were more likely to use clinical practice guidelines when they were expected to by physician and nurse colleagues, they perceived fewer barriers, or they held advanced oncology certification. This study was the first to assess oncology nurses' reported use of NCCN clinical practice guidelines for CIN and FN. It also demonstrated the feasibility of partnering with ONS for Web-based survey research. The findings give insight into work-place barriers to evidence-based practice in various settings. Expanding dissemination and implementation of clinical practice guideline recommendations will support the development of oncology nursing standards for risk assessment, management, and patient and family education in CIN and FN.

Midwives are actively involved in providing dietary advice to pregnant women. In order to describe the current status of prenatal dietary advice provided by midwives, we conducted a questionnaire survey inquiring about their knowledge and usage of the "Dietary Guidelines for Pregnant and Lactating Women" (Guidelines) issued by the Ministry of Health, Labour, and Welfare in 2006. In total, 2000 members of the Japanese Midwives' Association were randomly selected for administration of the questionnaire. The recovery rate was 42.1%, and 785 responses were eligible for analyses. The questionnaire collected information on the respondent's age, years of work experience, current involvement in delivery practice, number of deliveries per year in the current affiliation, provision of dietary advice to pregnant women, and knowledge and usage of the Guidelines. The proportion of respondents in their 20 s was low (1.8%). About half of the respondents were practicing delivery. Further, 66.1% (519 midwives) reported they had knowledge of the Guidelines. Among those who had knowledge of the Guidelines and were currently providing dietary advice (426 midwives), 88.0% were using the Guidelines. The most frequently used item in the Guidelines was "Diet for preventing anemia" (75.8%). The least used item was "Shoku-iku (diet and nutrition education) for pregnant and lactating women" (58.5%). Midwives who were practicing delivery showed a significantly lower usage of the Guidelines than those who were not (84.9% vs. 92.6%, P = 0.02). Among midwives practicing delivery, the most common reason for not using the Guidelines was "using original educational material produced by oneself or the facility." Providing dietary advice to pregnant women constituted a large fraction of midwives' duties as well as delivery practice. About 90% of the midwives, who had knowledge of the Guidelines and provided dietary advice, were using the Guidelines. In order to increase the usage of individual items of the Guidelines, ready-to-use brochures should be developed for midwives.

The Society for Academic Continuing Medical Education commissioned a study to clarify and, if possible, standardize the terminology for a set of important educational interventions. In the form of a guideline, this article describes one such intervention, practice facilitation, which is a common strategy in primary care to help practices develop capacity and infrastructure to support their ability to improve patient care. Based on a review of recent evidence and a facilitated discussion with US and Canadian experts, we describe practice facilitation, its terminology, and other important information about the intervention. We encourage leaders and researchers to consider and build on this guideline as they plan, implement, evaluate, and report practice facilitation efforts. Clear and consistent use of terminology is imperative, along with complete and accurate descriptions of interventions, to improve the use and study of practice facilitation.

Evidence demonstrates that providing nutritional support to intensive care unit (ICU) patients within 24 hours of ICU admission reduces mortality. However, early feeding is not universally practiced. Changing practice in complex multidisciplinary environments is difficult. Evidence supporting whether guidelines can improve ICU feeding practices and patient outcomes is contradictory. To determine whether evidence-based feeding guidelines, implemented using a multifaceted practice change strategy, improve feeding practices and reduce mortality in ICU patients. Cluster randomized trial in ICUs of 27 community and tertiary hospitals in Australia and New Zealand. Between November 2003 and May 2004, 1118 critically ill adult patients expected to remain in the ICU longer than 2 days were enrolled. All participants completed the study. Intensive care units were randomly assigned to guideline or control groups. Guideline ICUs developed an evidence-based guideline using Browman's Clinical Practice Guideline Development Cycle. A practice-change strategy composed of 18 specific interventions, leveraged by educational outreach visits, was implemented in guideline ICUs. Hospital discharge mortality. Secondary outcomes included ICU and hospital length of stay, organ dysfunction, and feeding process measures. Guideline and control ICUs enrolled 561 and 557 patients, respectively. Guideline ICUs fed patients earlier (0.75 vs 1.37 mean days to enteral nutrition start; difference, -0.62 [95% confidence interval {CI}, -0.82 to -0.36]; P < .001 and 1.04 vs 1.40 mean days to parenteral nutrition start; difference, -0.35 [95% CI, -0.61 to -0.01]; P = .04) and achieved caloric goals more often (6.10 vs 5.02 mean days per 10 fed patient-days; difference, 1.07 [95% CI, 0.12 to 2.22]; P = .03). Guideline and control ICUs did not differ with regard to hospital discharge mortality (28.9% vs 27.4%; difference, 1.4% [95% CI, -6.3% to 12.0%]; P = .75) or to hospital length of stay (24.2 vs 24.3 days; difference, -0.08 [95% CI, -3.8 to 4.4]; P = .97) or ICU length of stay (9.1 vs 9.9 days; difference, -0.86 [95% CI, -2.6 to 1.3]; P = .42). Using a multifaceted practice change strategy, ICUs successfully developed and introduced an evidence-based nutritional support guideline that promoted earlier feeding and greater nutritional adequacy. However, use of the guideline did not improve clinical outcomes. Trial Registration anzctr.org.au Identifier: ACTRN12608000407392.

Adapting heart failure guidelines for nursing care in home health settings: challenges and solutions.

Nurses provide most of home health services for patients with heart failure, and yet there are no evidence-based practice guidelines developed for home health nurses. The purpose of this article was to review the challenges and solutions for adapting generally available HF clinical practice guidelines to home health nursing. Appropriate HF guidelines were identified and home health nursing-relevant guidelines were extracted by the research team. In addition, a team of nursing academic and practice experts evaluated the extracted guidelines and reached consensus through Delphi rounds. We identified 172 recommendations relevant to home health nursing from the American Heart Association and Heart Failure Society of America guidelines. The recommendations were divided into 5 groups (generic, minority populations, normal ejection fraction, reduced ejection fraction, and comorbidities) and further subgroups. Experts agreed that 87% of the recommendations selected by the research team were relevant to home health nursing and rejected 6% of the selected recommendations. Experts' opinions were split on 7% of guideline recommendations. Experts mostly disagreed on recommendations related to HF medication and laboratory prescription as well as HF patient assessment. These disagreements were due to lack of patient information available to home health nurses as well as unclear understanding of scope of practice regulations for home health nursing. After 2 Delphi rounds over 8 months, we achieved 100% agreement on the recommendations. The finalized guideline included 153 recommendations. Guideline adaptation projects should include a broad scope of nursing practice recommendations from which home health agencies can customize relevant recommendations in accordance with available information and state and agency regulations.

To describe the suggested clinical practice of palliative sedation as it is presented in the literature and discuss available guidelines for its use. CINAHL, PubMed, and Web of Science were searched for publications since 1997 for recommended guidelines and position statements on palliative sedation as well as data on its provision. Keywords included palliative sedation, terminal sedation, guidelines, United States, and end of life. Inclusion criteria were palliative sedation policies, frameworks, guidelines, or discussion of its practice, general or oncology patient population, performance of the intervention in an inpatient unit, for humans, and in English. Exclusion criteria were palliative sedation in children, acute illness, procedural, or burns, and predominantly ethical discussions. Guidelines were published by American College of Physicians-American Society of Internal Medicine (2000), Hospice and Palliative Nurses Association (2003), American Academy of Hospice and Palliative Medicine (2006), American Medical Association (2008), Royal Dutch Medical Association (2009), European Association for Palliative Care (2009), National Hospice and Palliative Care Organization (2010), and National Comprehensive Cancer Network (2012). Variances throughout guidelines include definitions of the practice, indications for its use, continuation of life-prolonging therapies, medications used, and timing/prognosis. The development and implementation of institutional-based guidelines with clear stance on the discussed variances is necessary for consistency in practice. Data on provision of palliative sedation after implementation of guidelines needs to be collected and disseminated for a better understanding of the current practice in the United States. © The Author(s) 2014.

[Implementation of clinical practice guidelines: how can we close the evidence-practice gap?].

PubMed

Muche-Borowski, Cathleen; Nothacker, M; Kopp, I

2015-01-01

Guidelines are intended as instruments of knowledge transfer to support decision-making by physicians, other health professionals and patients in clinical practice and thereby contribute to quality improvements in healthcare. To date they are an indispensable tool for healthcare. Their benefit for patients can only be seen in application, i.e. the implementation of guideline recommendations. For successful implementation, implementability and practicability play a crucial role and these characteristics can be influenced and should be promoted by the guideline development group. In addition, a force field analysis to identify barriers against and facilitators for the implementation of specific guideline recommendations from the perspective of physicians and patients is recommended to guide the development of an individual implementation strategy and the selection of appropriate interventions. However, implementation cannot be achieved by the guideline development group alone and a universal implementation strategy does not exist. Therefore, a process using theory, analysis, experience and shared responsibility of stakeholders in healthcare is recommended, with the aim to achieve sustainable behavioral change and improve the quality of care by guideline-oriented behavior.

Clinical practice guideline development manual: a quality-driven approach for translating evidence into action.

PubMed

Rosenfeld, Richard M; Shiffman, Richard N

2009-06-01

Guidelines translate best evidence into best practice. A well-crafted guideline promotes quality by reducing health-care variations, improving diagnostic accuracy, promoting effective therapy, and discouraging ineffective-or potentially harmful-interventions. Despite a plethora of published guidelines, methodology is often poorly defined and varies greatly within and among organizations. This manual describes the principles and practices used successfully by the American Academy of Otolaryngology-Head and Neck Surgery to produce quality-driven, evidence-based guidelines using efficient and transparent methodology for action-ready recommendations with multidisciplinary applicability. The development process, which allows moving from conception to completion in 12 months, emphasizes a logical sequence of key action statements supported by amplifying text, evidence profiles, and recommendation grades that link action to evidence. As clinical practice guidelines become more prominent as a key metric of quality health care, organizations must develop efficient production strategies that balance rigor and pragmatism. Equally important, clinicians must become savvy in understanding what guidelines are-and are not-and how they are best utilized to improve care. The information in this manual should help clinicians and organizations achieve these goals.

Compared with the current focus on the development of clinical practice guidelines the effort devoted to their evaluation is meagre. Yet the ultimate success of guidelines depends on routine evaluation. Three types of evaluation are identified: evaluation of guidelines under development and before dissemination and implementation, evaluation of health care programs in which guidelines play a central role, and scientific evaluation, through studies that provide the scientific knowledge base for further evolution of guidelines. Identification of evaluation and program goals, evaluation design and a framework for evaluation planning are discussed. PMID:7489550

Characteristics of communication guidelines that facilitate or impede guideline use: a focus group study

Veldhuijzen, Wemke; Ram, Paul M; van der Weijden, Trudy; Niemantsverdriet, Susan; van der Vleuten, Cees PM

2007-01-01

Background The quality of doctor-patient communication has a major impact on the quality of medical care. Communication guidelines define best practices for doctor patient communication and are therefore an important tool for improving communication. However, adherence to communication guidelines remains low, despite doctors participating in intensive communication skill training. Implementation research shows that adherence is higher for guidelines in general that are user centred and feasible, which implies that they are consistent with users' opinions, tap into users' existing skills and fit into existing routines. Developers of communication guidelines seem to have been somewhat negligent with regard to user preferences and guideline feasibility. In order to promote the development of user centred and practicable communication guidelines, we elicited user preferences and identified which guideline characteristics facilitate or impede guideline use. Methods Seven focus group interviews were conducted with experienced GPs, communication trainers (GPs and behavioural scientists) and communication learners (GP trainees and medical students) and three focus group interviews with groups of GP trainees only. All interviews were transcribed and analysed qualitatively. Results The participants identified more impeding guideline characteristics than facilitating ones. The most important impeding characteristic was that guidelines do not easily fit into GPs' day-to-day practice. This is due to rigidity and inefficiency of communication guidelines and erroneous assumptions underpinning guideline development. The most important facilitating characteristic was guideline structure. Guidelines that were structured in distinct phases helped users to remain in control of consultations, which was especially useful in complicated consultations. Conclusion Although communication guidelines are generally considered useful, especially for structuring consultations, their usefulness is impaired by lack of flexibility and applicability to practice routines. User centred and feasible guidelines should combine the advantages of helping doctors to structure consultations with flexibility to tailor communication strategies to specific contexts and situations.

Evidence-based clinical practice guidelines may improve treatment quality, but the uptake of guideline recommendations is often incomplete and slow. Recently new low back pain guidelines are being launched in Denmark. The guidelines are considered to reduce personal and public costs. The aim of this study is to evaluate whether a complex, multifaceted implementation strategy of the low back pain guidelines will reduce secondary care referral and improve patient outcomes compared to the usual simple implementation strategy. In a two-armed cluster randomised trial, 100 general practices (clusters) and 2,700 patients aged 18 to 65 years from the North Denmark region will be included. Practices are randomly allocated 1:1 to a simple or a complex implementation strategy. Intervention practices will receive a complex implementation strategy, including guideline facilitator visits, stratification tools, and quality reports on low back pain treatment. Primary outcome is referral to secondary care. Secondary outcomes are pain, physical function, health-related quality of life, patient satisfaction with care and treatment outcome, employment status, and sick leave. Primary and secondary outcomes pertain to the patient level. Assessments of outcomes are blinded and follow the intention-to-treat principle. Additionally, a process assessment will evaluate the degree to which the intervention elements will be delivered as planned, as well as measure changes in beliefs and behaviours among general practitioners and patients. This study provides knowledge concerning the process and effect of an intervention to implement low back pain guidelines in general practice, and will provide insight on essential elements to include in future implementation strategies in general practice.

Smoking cessation treatment practices described by the 5 A's (ask, advise, assess, assist, arrange) are not well applied at cardiology wards because of various reasons, such as a lack of time and appropriate skills of the nursing staff. Therefore, a simplified guideline proposing an ask-advise-refer (AAR) strategy was introduced in Dutch cardiac wards. This study aimed to identify factors that determine the intentions of cardiac ward heads in adopting the simplified AAR guideline, as ward heads are key decision makers in the adoption of new guidelines. Ward heads' perceptions of current smoking cessation practices at the cardiac ward were also investigated. A cross-sectional survey with written questionnaires was conducted among heads of cardiology wards throughout the Netherlands, of whom 117 (64%) responded. According to the heads of cardiac wards, smoking cessation practices by cardiologists and nurses were mostly limited to brief practices that are easy to conduct. Only a minority offered intensive counseling or arranged follow-up contact. Heads with strong intentions of adopting the AAR guideline differed significantly on motivational and organizational attributes and perceived more smoking cessation assistance by other health professionals than did heads with weak intentions of adopting. Positive attitudes, social support toward adoption, and perception of much assistance at the ward were significantly associated with increased intentions to adopt the AAR guideline. Brief smoking cessation practices are adequately performed at cardiac wards, but the most effective practices, offering assistance and arranging for follow-up, are less than optimal. The AAR guideline offers a more feasible approach for busy cardiology wards. To ensure successful adoption of this guideline, the heads of cardiac wards should be convinced of its advantages and be encouraged by a supportive work environment. Policies may also facilitate the adoption of the AAR guideline.

For this purpose, a questionnaire which was developed by the members of the World Dental Federation, European Regional Organization Working Group - 'Relation Between Dental Practitioner and Universities', was implemented by the National Dental Associations of six European Regional Organization-zone countries (Georgian Stomatological Association - Georgia, Associazione Nazionale Dentisti Italiani - Italy, Portuguese Dental Association - Portugal, Russian Dental Association - Russia, Swiss Dental Association - Switzerland, and Turkish Dental Association - Turkey. The questionnaire was filled by a total of 910 dental professionals who are members of one of these national dental associations and who voluntarily wanted to participate to this survey. Most of the survey participants were familiar with clinical dental guidelines (68%), claimed that they implemented them into daily practice (61.7%), and generally acknowledged their benefits (81.8%). Many participants believed that clinical dental guidelines could help to improve the clinical treatment plan (50.6 %) and the accuracy of diagnosis (39.4%); which increased with age and years of practice (p < 0.05). The most frequently perceived barrier to the effective implementation of clinical dental guidelines was expressed as 'lack of awareness', while participants suggested a role for national dental associations in spreading clinical dental guidelines. A better understanding of the perceptions and attitudes of dentists towards clinical dental guidelines and the potential impact of factors affecting such perceptions and attitudes may be of particular importance for attempts aiming at overcoming the barriers for effective implementation of clinical dental guidelines into daily practice. Despite a significant familiarity and a common positive attitude, dental professionals are likely to have different perceptions towards clinical dental guidelines, especially regarding their effective implementation into daily practice, benefits and barriers.

Khan, Sohail Ahmad; Rodrigues, Gabrial; Kumar, Pramod; Rao, Padma G M

2006-06-01

To study the impact of guidelines on surgical antibiotic prophylaxis in clinical practice, barriers involved in adherence to guidelines and how to overcome the same. Literature pertaining to prophylactic antibiotic usage was searched. Medscape, Medline, Cochrane, Surgical Infection Prevention (SIP) project databases were reviewed. Recent articles from relevant journals, texts, and standard guidelines were also studied. Local guidelines seem more likely to be accepted and followed than those developed nationally. Major barriers involved in adherence to guidelines include lack of awareness about the guidelines, general perception of guideline as a bureaucratic rather than educational tool. Some practitioners perceive guidelines as "cookbook medicine" that does not permit them to make their own medical decisions. Other barriers are complex, multi-step systems that create confusion, decrease accountability. Methods for guideline adherence include surveillance and data analysis, new systems to facilitate documentation and improving workflow, education regarding current evidence-based guidelines and promoting the development of local guidelines or protocol, development and implementation of reminders to facilitate adherence to the local guidelines. A multidisciplinary steering team of surgeons, infectious disease specialists, pharmacists, anesthesiologists, microbiologists and nurses should develop local guidelines suitable to their institution and methods for adherence to prevent the surgical site infections. The gap between evidence-based guidelines and practice must be addressed in order to achieve optimal practice in this domain.

Closing the clinical gap: translating best practice knowledge to performance with guidelines implementation.

PubMed

Ishii, Lisa E

2013-06-01

Unsustainable health care costs coupled with opportunity for improvement in health care outcomes in the United States are stimulating meaningful transformation in the way we deliver care. One approach in this transformation focuses on minimizing unnecessary variation in physician practices, instead focusing on evidence-based medicine in a more uniform manner. Clinical practice guidelines contain evidence-based recommendations, articulate goals of care, and can help to reduce unnecessary variation. While thousands of clinical practice guidelines are in existence, a clinical gap exists between knowledge and clinical performance. With thoughtful guidelines implementation strategies in place, organizations can begin to close the gap and translate best practice knowledge into care. Health systems that have done this effectively have seen improved clinical outcomes, improved patient satisfaction, and lower cost per patient.

Clinical practice guidelines are tools that have been able to streamline decisions made in health issues and to decrease the gap between clinical action and scientific evidence. The objective of the study is to share the experience in the development and to update the guidelines by the National Health System of Mexico. The methodology in the development of the guidelines consists of 5 phases: prioritisation, establishment of work groups, development by adoption of international guidelines of de novo, validation and integration in the Master catalogue of clinical practice guidelines for its dissemination. The Master catalogue of clinical practice guidelines contains 664 guidelines, distributed in 42% Internal Medicine, 22% Surgery, 24% Pediatrics and 12% Gynecology. From the total of guidelines coverage is granted at an 85% of the Universal catalogue of health services, an 84% of the Catastrophic expenses protection fund and a 61% of the XXI Century Medical Insurance of the National Commission of Social Protection in Health. The result is the sum of a great effort of coordination and cooperation between the institutions of the National Health System, political wills and a commitment of 3,477 health professionals that participate in guidelines' development and update. Master catalogue guidelines' integration, diffusion and implantation improve quality of attention and security of the users of the National Health System.

The National Library for Health offers a comprehensive searchable database of nationally approved clinical guidelines, called the Guidelines Finder. This resource, commissioned in 2002, is managed and developed by the University of Sheffield Health Sciences Library. The authors introduce the historical and political dimension of guidelines and the nature of guidelines as a mechanism to ensure clinical effectiveness in practice. The article then outlines the maintenance and organisation of the Guidelines Finder database itself, the criteria for selection, who publishes guidelines and guideline formats, usage of the Guidelines Finder service and finally looks at some lessons learnt from a local library offering a national service. Clinical guidelines are central to effective clinical practice at the national, organisational and individual level. The Guidelines Finder is one of the most visited resources within the National Library for Health and is successful in answering information needs related to specific patient care, clinical research, guideline development and education.

Clinical Practice Guidelines are clinical tools addressed to medical and health professionals and are normally employed to improve quality and safety of diagnostic and therapeutical procedures but may sometimes limit the autonomy of medical and other health care professionals. The adherence to Clinical Practice Guidelines should not be an exclusive step to evaluate the liability and respect of standards of care in case of medico-legal investigations being each clinical case very specific. Medical liability and respect of standards of care should be evaluated with the support of Clinical Practice Guidelines and the extensive examination of all specific features, professional background and experience requested to treat each single patient.

To gain a better understanding of factors influencing clinicians' embryo transfer practices. Cross-sectional survey. Web-based survey conducted in December 2008 of individuals practicing IVF in centers registered with the Society for Assisted Reproductive Technology (SART). None. None. Prevalence of clinicians reporting following embryo transfer guidelines recommended by the American Society for Reproductive Medicine (ASRM), prevalence among these clinicians to deviate from ASRM guidelines in commonly encountered clinical scenarios, and practice patterns related to single embryo transfer. Six percent of respondents reported following their own, independent guidelines for the number of embryos to transfer after IVF. Of the 94% of respondents who reported routinely following ASRM embryo transfer guidelines, 52% would deviate from these guidelines for patient request, 51% for cycles involving the transfer of frozen embryos, and 70% for patients with previously failed IVF cycles. All respondents reported routinely discussing the risks of multiple gestations associated with standard embryo transfer practices, whereas only 34% reported routinely discussing single embryo transfer with all patients. Although the majority of clinicians responding to our survey reported following ASRM embryo transfer guidelines, at least half would deviate from these guidelines in a number of different situations.

Decision-support systems based on clinical practice guidelines can support physicians and other health-care personnel in the process of following best practice consistently. A knowledge-based approach to represent guidelines makes it possible to encode computer-interpretable guidelines in a formal manner, perform consistency checks, and use the guidelines directly in decision-support systems. Decision-support authors and guideline users require guidelines in human-readable formats in addition to computer-interpretable ones (e.g., for guideline review and quality assurance). We propose a new document-oriented information architecture that combines knowledge-representation models with electronic and paper documents. The approach integrates decision-support modes with standard document formats to create a combined clinical-guideline model that supports on-line viewing, printing, and decision support.

Clinical practice guideline (CPG), clinical practice algorithm (CPA), and clinical checklist (CC, collectively CPGAC) development is a high priority of the American Association of Clinical Endocrinologists (AACE) and American College of Endocrinology (ACE). This 2017 update in CPG development consists of (1) a paradigm change wherein first, environmental scans identify important clinical issues and needs, second, CPA construction focuses on these clinical issues and needs, and third, CPG provide CPA node/edge-specific scientific substantiation and appended CC; (2) inclusion of new technical semantic and numerical descriptors for evidence types, subjective factors, and qualifiers; and (3) incorporation of patient-centered care components such as economics and transcultural adaptations, as well as implementation, validation, and evaluation strategies. This third point highlights the dominating factors of personal finances, governmental influences, and third-party payer dictates on CPGAC implementation, which ultimately impact CPGAC development.

The practice guidelines of the American College of Medical Genetics and Genomics (ACMG) and the National Society of Genetic Counselors (NSGC) are developed by members of the ACMG and NSGC to assist medical geneticists, genetic counselors, and other health-care providers in making decisions about appropriate management of genetic concerns, including access to and/or delivery of services. Each practice guideline focuses on a clinical or practice-based issue and is the result of a review and analysis of current professional literature believed to be reliable. As such, information and recommendations within the ACMG and NSGC joint practice guidelines reflect the current scientific and clinical knowledge at the time of publication, are current only as of their publication date, and are subject to change without notice as advances emerge. In addition, variations in practice, which take into account the needs of the individual patient and the resources and limitations unique to the institution or type of practice, may warrant approaches, treatments, and/or procedures that differ from the recommendations outlined in this guideline. Therefore, these recommendations should not be construed as dictating an exclusive course of management, nor does the use of such recommendations guarantee a particular outcome. Genetic counseling practice guidelines are never intended to displace a health-care provider's best medical judgment based on the clinical circumstances of a particular patient or patient population. Practice guidelines are published by the ACMG or the NSGC for educational and informational purposes only, and neither the ACMG nor the NSGC "approve" or "endorse" any specific methods, practices, or sources of information.Cancer genetic consultation is an important aspect of the care of individuals at increased risk of a hereditary cancer syndrome. Yet several patient, clinician, and system-level barriers hinder identification of individuals appropriate for cancer genetics referral. Thus, the purpose of this practice guideline is to present a single set of comprehensive personal and family history criteria to facilitate identification and maximize appropriate referral of at-risk individuals for cancer genetic consultation. To develop this guideline, a literature search for hereditary cancer susceptibility syndromes was conducted using PubMed. In addition, GeneReviews and the National Comprehensive Cancer Network guidelines were reviewed when applicable. When conflicting guidelines were identified, the evidence was ranked as follows: position papers from national and professional organizations ranked highest, followed by consortium guidelines, and then peer-reviewed publications from single institutions. The criteria for cancer genetic consultation referral are provided in two formats: (i) tables that list the tumor type along with the criteria that, if met, would warrant a referral for a cancer genetic consultation and (ii) an alphabetical list of the syndromes, including a brief summary of each and the rationale for the referral criteria that were selected. Consider referral for a cancer genetic consultation if your patient or any of their first-degree relatives meet any of these referral criteria.

Guidelines for computer security in general practice.

As general practice becomes increasingly computerised, data security becomes increasingly important for both patient health and the efficient operation of the practice. To develop guidelines for computer security in general practice based on a literature review, an analysis of available information on current practice and a series of key stakeholder interviews. While the guideline was produced in the context of Australian general practice, we have developed a template that is also relevant for other countries. Current data on computer security measures was sought from Australian divisions of general practice. Semi-structured interviews were conducted with general practitioners (GPs), the medical software industry, senior managers within government responsible for health IT (information technology) initiatives, technical IT experts, divisions of general practice and a member of a health information consumer group. The respondents were asked to assess both the likelihood and the consequences of potential risks in computer security being breached. The study suggested that the most important computer security issues in general practice were: the need for a nominated IT security coordinator; having written IT policies, including a practice disaster recovery plan; controlling access to different levels of electronic data; doing and testing backups; protecting against viruses and other malicious codes; installing firewalls; undertaking routine maintenance of hardware and software; and securing electronic communication, for example via encryption. This information led to the production of computer security guidelines, including a one-page summary checklist, which were subsequently distributed to all GPs in Australia. This paper maps out a process for developing computer security guidelines for general practice. The specific content will vary in different countries according to their levels of adoption of IT, and cultural, technical and other health service factors. Making these guidelines relevant to local contexts should help maximise their uptake.

Developing clinical practice guidelines: reviewing, reporting, and publishing guidelines; updating guidelines; and the emerging issues of enhancing guideline implementability and accounting for comorbid conditions in guideline development

PubMed Central

2012-01-01

Clinical practice guidelines are one of the foundations of efforts to improve health care. In 1999, we authored a paper about methods to develop guidelines. Since it was published, the methods of guideline development have progressed both in terms of methods and necessary procedures and the context for guideline development has changed with the emergence of guideline clearing houses and large scale guideline production organisations (such as the UK National Institute for Health and Clinical Excellence). It therefore seems timely to, in a series of three articles, update and extend our earlier paper. In this third paper we discuss the issues of: reviewing, reporting, and publishing guidelines; updating guidelines; and the two emerging issues of enhancing guideline implementability and how guideline developers should approach dealing with the issue of patients who will be the subject of guidelines having co-morbid conditions.

prescription rates of antidepressants during pregnancy range from 2-3% in The Netherlands to 6.2% in the USA. Inconclusive evidence about harms and benefits of antidepressants during pregnancy leads to variation in advice given by gynaecologists and midwives. The objective was to investigate familiarity with, and adherence to the Dutch multidisciplinary guideline on Selective Serotonin Reuptake Inhibitor (SSRI) use during pregnancy by gynaecologists and midwives in the Netherlands. an online survey was developed and send to Dutch gynaecologists and midwives. The survey consisted mainly of multiple-choice questions addressing guideline familiarity and current practice of the respondent. Also, caregiver characteristics associated with guideline adherence were investigated. a total of 178 gynaecologists and 139 midwives responded. Overall familiarity with the Dutch guideline was 92.7%. However, current practice and advice given to patients by caregivers differed substantially, both between gynaecologists and midwives as well as within both professions. Overall guideline adherence was 13.9%. Multivariable logistic regression showed that solely caregiver profession was associated with guideline adherence, with gynaecologists having a higher adherence rate (OR 2.10, 95%CI 1.02-4.33) than midwives. although reported familiarity with the guideline is high, adherence to the guideline is low, possibly resulting in advice to patients that is inconsistent with guidelines and unwanted variation in current practice. further implementation of the recommendations as given in the guideline should be stimulated. Additional research is needed to examine how gynaecologists and midwives can be facilitated to follow the recommendations of the clinical guideline on SSRI use during pregnancy.

- The incorporation of best practice guidelines into one's institution is a challenging goal of utilization management, and the successful adoption of such guidelines depends on institutional context. Laboratorians who have access to key clinical data are well positioned to understand existing local practices and promote more appropriate laboratory testing. - To apply a novel approach to utilization management by reviewing international clinical guidelines and current institutional practices to create a reliable mechanism to improve detection and reduce unnecessary tests in our patient population. - We targeted a frequently ordered genetic test for HFE-related hereditary hemochromatosis, a disorder of low penetrance. After reviewing international practice guidelines, we evaluated 918 HFE tests and found that all patients with new diagnoses had transferrin saturation levels that were significantly higher than those of patients with nonrisk genotypes (72% versus 42%; P < .001). - Our "one-button" order that restricts HFE genetic tests to patients with transferrin saturation greater than 45% is consistent with published practice guidelines and detected 100% of new patients with HFE-related hereditary hemochromatosis. - Our proposed algorithm differs from previously published approaches in that it incorporates both clinical practice guidelines and local physician practices, yet requires no additional hands-on effort from pathologists or clinicians. This novel approach to utilization management embraces the role of pathologists as leaders in promoting high-quality patient care in local health care systems.

Guidelines for Good Epidemiology Practices for Occupational and Environmental Epidemiologic Research. The Chemical Manufacturers Association's Epidemiology Task Group.

1991-12-01

The Guidelines for Good Epidemiology Practices (GEPs) for Occupational and Environmental Epidemiologic Research address the conduct of studies generally undertaken to answer questions about human health in relationship to the work place or the environment. The GEPs propose minimum practices and procedures that should be considered to help ensure the quality and integrity of data used in epidemiologic research and to provide adequate documentation of the research methods. The GEPs address the process of conducting individual epidemiologic studies and do not prescribe specific research methods. The Guidelines for Good Epidemiology Practices propose minimum practices and procedures in the following areas: I. Organization and Personnel II. Facilities, Resource Commitment, and Contractors III. Protocol IV. Review and Approval V. Study Conduct VI. Communication VII. Archiving VIII. Quality Assurance Although the Guidelines for Good Epidemiology Practices will not guarantee good epidemiology, they do provide a useful framework for ensuring that all research issues are adequately addressed. This framework is proposed as a first step in improving epidemiologic research practices through adherence to sound scientific research principles. Appendices provide an overview of standard operating procedures, a glossary of terms used in the Guidelines, and suggested references on occupational epidemiology methods.

In 2001, the ARIA guidelines were published to assist healthcare practitioners in managing allergic rhinitis (AR) according to the best evidence. Very limited information, however, is avail-able on the impact of these guidelines on clinical practice. All Belgian Otorhinolaryngologists were invited to complete a questionnaire, covering demographic and professional characteristics, knowledge, use and perception of the ARIA guidelines and 4 clinical case scenarios of AR. Of the 258 (44%) Belgian Otorhinolaryngologists who participated, almost 90% had ever heard about ARIA and 64% had followed a lecture specifically dedicated to the ARIA guidelines. Furthermore, 62% stated to always or mostly follow the ARIA treatment algorithms in the daily management of AR patients. In the clinical case section, adherence to the ARIA guidelines raised with increased self-reported knowledge and use of the ARIA guidelines and among participants that considered the guidelines more userfriendly. Of the respondents, 51% were considered as good com-pliers. Younger age was a significant predictor for good compliance. More efforts are required to improve the translation of scientific knowledge into clinical practice and to further identify which factors may influence guideline compliance.

Pre-post controlled study. Catalonia, autonomous community located in north-eastern Spain. Individuals aged 35-74 years assigned to general practitioners of the Catalan Health Institute. The intervention group consisted of individuals whose general practitioners had accessed the computerized clinical practice guidelines at least twice a day, while the control group consisted of individuals whose general practitioner had never accessed the computerized clinical practice guidelines platform. The Chi-squared test was used to detect significant differences in the follow-up, control, and treatment variables for all three disorders (hypertension, hypercholesterolaemia, and type 2 diabetes mellitus) between individuals assigned to users and non-users of the computerized clinical practice guidelines, respectively. A total of 189,067 patients were included in this study, with a mean age of 56 years (standard deviation 12), and 55.5% of whom were women. Significant differences were observed in hypertension management, treatment and control; type 2 diabetes mellitus management, treatment and diagnoses, and the management and control of hypercholesterolaemia in both sexes. Computerized clinical practice guidelines are an effective tool for the control and follow-up of patients diagnosed with hypertension, type 2 diabetes mellitus, and hypercholesterolaemia. The usefulness of computerized clinical practice guidelines to diagnose and adequately treat individuals with these disorders remains unclear. Copyright © 2016 Elsevier España, S.L.U.

To determine whether a collaborative learning strategy-derived clinical practice guideline can reduce the duration of endotracheal intubation following infant heart surgery. Prospective and retrospective data collected from the Pediatric Heart Network in the 12 months pre- and post-clinical practice guideline implementation at the four sites participating in the collaborative (active sites) compared with data from five Pediatric Heart Network centers not participating in collaborative learning (control sites). Ten children's hospitals. Data were collected for infants following two-index operations: 1) repair of isolated coarctation of the aorta (birth to 365 d) and 2) repair of tetralogy of Fallot (29-365 d). There were 240 subjects eligible for the clinical practice guideline at active sites and 259 subjects at control sites. Development and application of early extubation clinical practice guideline. After clinical practice guideline implementation, the rate of early extubation at active sites increased significantly from 11.7% to 66.9% (p < 0.001) with no increase in reintubation rate. The median duration of postoperative intubation among active sites decreased from 21.2 to 4.5 hours (p < 0.001). No statistically significant change in early extubation rates was found in the control sites 11.7% to 13.7% (p = 0.63). At active sites, clinical practice guideline implementation had no statistically significant impact on median ICU length of stay (71.9 hr pre- vs 69.2 hr postimplementation; p = 0.29) for the entire cohort. There was a trend toward shorter ICU length of stay in the tetralogy of Fallot subgroup (71.6 hr pre- vs 54.2 hr postimplementation, p = 0.068). A collaborative learning strategy designed clinical practice guideline significantly increased the rate of early extubation with no change in the rate of reintubation. The early extubation clinical practice guideline did not significantly change postoperative ICU length of stay.

[Practice guidelines in rehabilitation: infringement upon physicians' autonomy or foundation for better outcomes?].

Brüggemann, S; Korsukéwitz, C

2004-10-01

Clinical practice guidelines - seen as an aggregation of scientific evidence - and evidence based medicine are of relevance and importance for everybody involved in health care. Nevertheless, the discussion of their pros and cons is controversial. Major criticisms concern methodological aspects, a disregard of the patients' perspective, potentially increasing costs and the limitation of doctors' autonomy possibly caused by streamlining therapy. Supporters emphasize the improvement of care that comes with using proven therapies, patients' empowerment, cost reduction and equity in the distribution of resources. Following medical practice guidelines the liability for medical malpractice may be limited, but non-adherence to guidelines does not entail liability per se. Clinical practice guidelines in the rehabilitative sector differ from those in curative medicine by being required to achieve more complex goals than maintenance, recovery and improvement of health. Activities in the rehabilitation sector address two main topics: The integration of rehabilitation into curative guidelines, e. g. by participating in the German clearing process for guidelines, and the development of guidelines specific to rehabilitation. There are a number of guideline initiatives, e. g. with the Association of the Scientific Medical Societies (AWMF), the Federation of German Pension Insurance Institutes (VDR) and the Federal Insurance Institute for Salaried Employees (BfA). The BfA project is the first to allow integration of evidence based medicine into the quality assurance programme of the German Pension Insurance complementing it with differentiated criteria for the assessment of therapeutic processes. Taking evidence based medicine increasingly into consideration and the continuous process of introducing rehabilitative clinical practice guidelines are going to improve health care for people with chronic diseases.

Over recent decades, the number of available clinical practice guidelines has enormously grown. Guidelines should meet specific quality criteria to ensure good quality. There is a growing need for the developement of a set of criteria to ensure that potential biases inherent in guideline development have been properly addressed and that the recommendations for practice are valid and reliable. The AGREE-collaboration is an international network that developed an instrument to critically appraise the methodological quality of guidelines. AGREE promotes a clear strategy to produce, disseminate and evaluate guidelines of high quality. In the first phase of the international project the AGREE-instrument was tested in 11 different countries. Based on this experience the instrument was refined and optimised. In the second phase it was disseminated, promoted and evaluated in 18 participating countries. Belgium was one of them. The Belgian partner in the AGREE-project developed 3 workshops and established 13 validation committees to validate guidelines from Belgian developer groups. We collected 33 questionnaires from participants of the workshops and the validation committees, in which we asked for primary experiences and information on the usefulness and applicability of the instrument. We were also interested in the shortcomings of the instrument and potential strategies to bridge them. More efforts should be made to train methodological experts to gain certain skills for a critical appraisal of clinical practice guidelines. Promoting the AGREE-instrument will lead to a broader knowledge and use of quality criteria in guideline development and appraisal. The development and dissemination of an international list of criteria to appraise the quality of guidelines will stimulate the development of methodologically sound guidelines. International comparisons between existing guidelines will lead to a better collaboration between guideline developers throughout the world.

To evaluate the methodological quality of the Palestinian Clinical Practice Guideline for Diabetes Mellitus using the Translated Arabic Version of the AGREE II. Methodological evaluation. A cross-cultural adaptation framework was followed to translate and develop a standardised Translated Arabic Version of the AGREE II. Palestinian Primary Healthcare Centres. Sixteen appraisers independently evaluated the Clinical Practice Guideline for Diabetes Mellitus using the Translated Arabic Version of the AGREE II. Methodological quality of diabetic guideline. The Translated Arabic Version of the AGREE II showed an acceptable reliability and validity. Internal consistency ranged between 0.67 and 0.88 (Cronbach's α). Intra-class coefficient among appraisers ranged between 0.56 and 0.88. The quality of this guideline is low. Both domains 'Scope and Purpose' and 'Clarity of Presentation' had the highest quality scores (66.7% and 61.5%, respectively), whereas the scores for 'Applicability', 'Stakeholder Involvement', 'Rigour of Development' and 'Editorial Independence' were the lowest (27%, 35%, 36.5%, and 40%, respectively). The findings suggest that the quality of this Clinical Practice Guideline is disappointingly low. To improve the quality of current and future guidelines, the AGREE II instrument is extremely recommended to be incorporated as a gold standard for developing, evaluating or updating the Palestinian Clinical Practice Guidelines. Future guidelines can be improved by setting specific strategies to overcome implementation barriers with respect to economic considerations, engaging of all relevant end-users and patients, ensuring a rigorous methodology for searching, selecting and synthesising the evidences and recommendations, and addressing potential conflict of interests within the development group.

Patient-provider electronic communication has proliferated in recent years, yet there is a dearth of published research either leading to, or including, recommendations that improve clinical care and prevent unintended negative consequences. We critically appraise published guidelines and suggest an agenda for future work in this area. To understand how existing guidelines align with current practice, evidence, and technology. We performed a narrative review of provider-targeted guidelines for electronic communication between patients and providers, searching Ovid MEDLINE, Embase, and PubMed databases using relevant terms. We limited the search to articles published in English, and manually searched the citations of relevant articles. For each article, we identified and evaluated the suggested practices. Across 11 identified guidelines, the primary focus was on technical and administrative concerns, rather than on relational communication. Some of the security practices recommended by the guidelines are no longer needed because of shifts in technology. It is unclear the extent to which the recommendations that are still relevant are being followed. Moreover, there is no guideline-cited evidence of the effectiveness of the practices that have been proposed. Our analysis revealed major weaknesses in current guidelines for electronic communication between patients and providers: the guidelines appear to be based on minimal evidence and offer little guidance on how best to use electronic tools to communicate effectively. Further work is needed to systematically evaluate and identify effective practices, create a framework to evaluate quality of communication, and assess the relationship between electronic communication and quality of care.

Although several clinical practice guidelines have been developed in the last decades, cancer pain management is still deficient. The purpose of this work was to carry out a comprehensive and systematic literature review of current clinical practice guidelines on cancer pain management, and critically appraise their methodology and content in order to evaluate their quality and validity to cope with this public health issue. A systematic review was performed in the main databases, using English, French and Spanish as languages, from 2008 to 2013. Reporting and methodological quality was rated with the Appraisal of Guidelines, Research and Evaluation II (AGREE-II) tool, including an inter-rater reliability analysis. Guideline recommendations were extracted and classified into several categories and levels of evidence, aiming to analyse guidelines variability and evidence-based content comprehensiveness. Six guidelines were included. A wide variability was found in both reporting and methodological quality of guidelines, as well as in the content and the level of evidence of their recommendations. The Scottish Intercollegiate Guidelines Network guideline was the best rated using AGREE-II, while the Sociedad Española de Oncología Médica guideline was the worst rated. The Ministry of Health Malaysia guideline was the most comprehensive, and the Scottish Intercollegiate Guidelines Network guideline was the second one. The current guidelines on cancer pain management have limited quality and content. We recommend Ministry of Health Malaysia and Scottish Intercollegiate Guidelines Network guidelines, whilst Sociedad Española de Oncología Médica guideline still needs to improve.

In Ontario, Canada, the Registered Nurses' Association promotes a Best Practice Spotlight Organization initiative to enhance evidence-based practice. Qualifying organizations are required to implement strategies, evaluate outcomes, and sustain practices aligned with nursing clinical practice guidelines. This study reports on the development and evaluation of a multifaceted implementation strategy to support adoption of a nursing clinical practice guideline on the assessment and management of acute pain in a pediatric rehabilitation and complex continuing care hospital. Multiple approaches were employed to influence behavior, attitudes, and awareness around optimal pain practice (e.g., instructional resources, electronic reminders, audits, and feedback). Four measures were introduced to assess pain in communicating and noncommunicating children as part of a campaign to treat pain as the fifth vital sign. A prospective repeated measures design examined survey and audit data to assess practice aligned with the guideline. The Knowledge and Attitudes Survey (KNAS) was adapted to ensure relevance to the local practice setting and was assessed before and after nurses' participation in three education modules. Audit data included client demographics and pain scores assessed annually over a 3-year window. A final sample of 69 nurses (78% response rate) provided pre-/post-survey data. A total of 108 pediatric surgical clients (younger than 19 years) contributed audit data across the three collection cycles. Significant improvements in nurses' knowledge, attitudes, and behaviors related to optimal pain care for children with disabilities were noted following adoption of the pain clinical practice guideline. Targeted guideline implementation strategies are central to supporting optimal pain practice. Copyright © 2015 American Society for Pain Management Nursing. Published by Elsevier Inc.

The 2008 National Mastectomy and Breast Reconstruction Audit demonstrated marked variation in the practice and outcomes of breast reconstruction in the UK. To standardise practice and improve outcomes for patients, the British professional associations developed best-practice guidelines with specific guidance for newer mesh-assisted implant-based techniques. We explored the degree of uptake of best-practice guidelines within units performing implant-based reconstruction (IBBR) as the first phase of the implant Breast Reconstruction Evaluation (iBRA) study. A questionnaire developed by the iBRA Steering Group was completed by trainee and consultant leads at breast and plastic surgical units across the UK. Simple summary statistics were calculated for each survey item to assess compliance with current best-practice guidelines. 81 units from 79 NHS Trusts completed the questionnaire. Marked variation was observed in adherence to guidelines, especially those relating to clinical governance and infection prevention strategies. Less than half (n = 28, 47%) of units obtained local clinical governance board approval prior to offering new mesh-based techniques and prospective audit of the clinical, cosmetic and patient-reported outcomes of surgery was infrequent. Most units screened for methicillin-resistant staphylococcus aureus prior to surgery but fewer than 1 in 3 screened for methicillin-sensitive strains. Laminar-flow theatres (recommended for IBBR) were not widely-available with less than 1 in 5 units having regular access. Peri-operative antibiotics were widely-used, but the type and duration were highly-variable. The iBRA national practice questionnaire has demonstrated variation in reported practice and adherence to IBBR guidelines. High-quality evidence is urgently required to inform best practice.

NASA HQ established the NASA R&M Steering Committee (R&MSC) comprised of membership from each NASA field center. The primary charter of the R&MSC is to obtain, record, and share the best design practices that NASA has applied to successful space flight programs and current design considerations (guidelines) that should enhance flight reliability on emerging programs. The practices and guidelines are being assembled in a living document for distribution to NASA centers and the aerospace community. The document will be updated annually with additional practices and guidelines as contributions from the centers are reviewed and approved by the R&MSC. Practices and guidelines are not requirements, but rather a means of sharing procedures and techniques that a given center and the R&MSC together feel have strong technical merit and application to the design of space-related equipment.

Hypertension and diabetes, key risk factors for cardiovascular disease, are significant health problems globally. As cardiovascular disease is one of the leading causes of mortality in Mongolia since 2000, clinical guidelines on arterial hypertension and diabetes were developed and implemented in 2011. This paper explores the barriers and enablers influencing the implementation of these guidelines in the primary care setting. A phenomenological qualitative study with semi-structured interviews was conducted to explore the implementation of the diabetes and hypertension guidelines at the primary care level, as well as to gain insight into how practitioners view the usability and practicality of the guidelines. Ten family health centres were randomly chosen from a list of all the family health centres (n = 136) located in Ulaanbaatar City. In each centre, a focus group discussion with nurses (n = 20) and individual interviews with practice doctors (n = 10) and practice managers (n = 10) were conducted. Data was analysed using a thematic approach utilising the Theoretical Domains Framework. The majority of the study participants reported being aware of the guidelines and that they had incorporated them into their daily practice. They also reported having attended guideline training sessions which were focused on practice skill development. The majority of participants expressed satisfaction with the wide range of resources that had been supplied to them by the Mongolian Government to assist with the implementation of the guidelines. The resources, supplied from 2011 onwards, included screening devices, equipment for blood tests, medications and educational materials. Other enablers were the participants' commitment and passion for guideline implementation and their belief in the simplicity and practicality of the guidelines. Primary care providers reported a number of challenges in implementing the guidelines, including frustration caused by increased workload and long waiting times, time constraints, difficulties with conflicting tasks and low patient health literacy. This study provides evidence that comprehensive and rigorous dissemination and implementation strategies increase the likelihood of successful implementation of new guidelines in low resource primary care settings. It also offers some key lessons that might be carefully considered when other evidence-based clinical guidelines are to be put into effect in low resource settings and elsewhere.

Despite the availability of evidence-based guidelines for the management of low back pain (LBP) that contain consistent messages, large evidence-practice gaps in primary care remain. To perform a systematic review and metasynthesis of qualitative studies that have explored primary care clinicians' perceptions and beliefs about guidelines for LBP, including perceived enablers and barriers to guideline adherence. Studies investigating perceptions and beliefs about LBP guidelines were included if participants were primary care clinicians and qualitative methods had been used for both data collection and analysis. We searched major databases up to July 2014. Pairs of reviewers independently screened titles and abstracts, extracted data, appraised method quality using the CASP checklist, conducted thematic analysis, and synthesized the results in narrative format. Seventeen studies, with a total of 705 participants, were included. We identified 3 key emergent themes and 8 subthemes: (1) guideline implementation and adherence beliefs and perceptions; (2) maintaining the patient-clinician relationship with imaging referrals; and (3) barriers to guideline implementation. Clinicians believed that guidelines were categorical, prescriptive, and constrained professional practice; however, popular clinical practices superseded the guidelines. Imaging referrals were used to manage consultations and to obtain definitive diagnoses. Clinicians' perceptions reflected a lack of content knowledge and understanding of how guidelines are developed. Addressing misconceptions and other barriers to uptake of evidence-based guidelines for managing LBP is needed to improve knowledge transfer and close the evidence-practice gap in the treatment of this common condition.

This paper summarizes the guidelines published by the Osteoarthritis research society International (OARSI) and compares these guidelines with others. The OARSI guidelines are based on a systematic review of the literature, a meta-analysis and an expert consensus. The OARSI has developed 25 guidelines including 8 for pharmacology modalities, 12 for non-pharmacology modalities and 5 for surgery modalities. The usefulness of the guidelines in the daily practice is very low. The barriers for the guidelines implementation are the lack of interest of the practitioners, the lack of scientific advances in the OA diagnosis and treatments and the low applicability of these guidelines in the daily practice.

Symmetry in locomotor central pattern generators and animal gaits

Golubitsky, Martin; Stewart, Ian; Buono, Pietro-Luciano; Collins, J. J.

1999-10-01

Animal locomotion is controlled, in part, by a central pattern generator (CPG), which is an intraspinal network of neurons capable of generating a rhythmic output. The spatio-temporal symmetries of the quadrupedal gaits walk, trot and pace lead to plausible assumptions about the symmetries of locomotor CPGs. These assumptions imply that the CPG of a quadruped should consist of eight nominally identical subcircuits, arranged in an essentially unique matter. Here we apply analogous arguments to myriapod CPGs. Analyses based on symmetry applied to these networks lead to testable predictions, including a distinction between primary and secondary gaits, the existence of a new primary gait called `jump', and the occurrence of half-integer wave numbers in myriapod gaits. For bipeds, our analysis also predicts two gaits with the out-of-phase symmetry of the walk and two gaits with the in-phase symmetry of the hop. We present data that support each of these predictions. This work suggests that symmetry can be used to infer a plausible class of CPG network architectures from observed patterns of animal gaits.

The left end of rat L1 (L1Rn, long interspersed repeated) DNA which is a CpG island can function as a promoter.

Here we report that the 600 bp promoter-like region at the left end of a newly isolated and characterized rat L1 DNA element can activate the prokaryotic chloramphenicol acyltransferase gene in a rat cell line. Activation only occurs when the promoter region is oriented to the transferase gene as it is to the L1 protein encoding sequences and is 75% inhibited by methylation of just 5 of the 22 CpGs present in the promoter. The G + C rich promoter contains enough CpGs to qualify it as a CpG island, but in contrast to other CpG islands, genomic L1 promoters are fully methylated in both somatic cell and sperm DNA as judged by restriction enzyme analysis. Partial demethylation of the genomic promoters by treatment with 5-azacytidine failed to produce discrete L1 transcripts. The relationship of methylation to the evolutionary history and fate of the rat L1 promoter is discussed. Images PMID:2459662

Nucleosome dynamics and maintenance of epigenetic states of CpG islands

NASA Astrophysics Data System (ADS)

Sneppen, Kim; Dodd, Ian B.

2016-06-01

Methylation of mammalian DNA occurs primarily at CG dinucleotides. These CpG sites are located nonrandomly in the genome, tending to occur within high density clusters of CpGs (islands) or within large regions of low CpG density. Cluster methylation tends to be bimodal, being dominantly unmethylated or mostly methylated. For CpG clusters near promoters, low methylation is associated with transcriptional activity, while high methylation is associated with gene silencing. Alternative CpG methylation states are thought to be stable and heritable, conferring localized epigenetic memory that allows transient signals to create long-lived gene expression states. Positive feedback where methylated CpG sites recruit enzymes that methylate nearby CpGs, can produce heritable bistability but does not easily explain that as clusters increase in size or density they change from being primarily methylated to primarily unmethylated. Here, we show that an interaction between the methylation state of a cluster and its occupancy by nucleosomes provides a mechanism to generate these features and explain genome wide systematics of CpG islands.

Clinical practice guideline development manual: A quality-driven approach for translating evidence into action

Background Guidelines translate best evidence into best practice. A well-crafted guideline promotes quality by reducing healthcare variations, improving diagnostic accuracy, promoting effective therapy, and discouraging ineffective – or potentially harmful – interventions. Despite a plethora of published guidelines, methodology is often poorly defined and varies greatly within and among organizations. Purpose This manual describes the principles and practices used successfully by the American Academy of Otolaryngology – Head and Neck Surgery to produce quality-driven, evidence-based guidelines using efficient and transparent methodology for action-ready recommendations with multi-disciplinary applicability. The development process, which allows moving from conception to completion in twelve months, emphasizes a logical sequence of key action statements supported by amplifying text, evidence profiles, and recommendation grades that link action to evidence. Conclusions As clinical practice guidelines become more prominent as a key metric of quality healthcare, organizations must develop efficient production strategies that balance rigor and pragmatism. Equally important, clinicians must become savvy in understanding what guidelines are – and are not – and how they are best utilized to improve care. The information in this manual should help clinicians and organizations achieve these goals. PMID:19464525

Evidence-based practice guidelines in OHS: are they agree-able?

Hulshof, Carel; Hoenen, John

2007-01-01

The purpose of this study was to evaluate the acceptance, validity, reliability and feasibility of the AGREE (Appraisal of Guidelines and REsearch and Evaluation) instrument to assess the quality of evidence-based practice guidelines for occupational physicians. In total, 6 practice guidelines of the Netherlands Society of Occupational Medicine (NVAB) were appraised by 20 occupational health professionals and experts in guideline development or implementation. Although appraisers often disagreed on individual item scores, the internal consistency and interrater reliability for most domains was sufficient. The AGREE criteria were in general considered relevant and no major suggestions for additional items for use in the context of occupational health were brought up. The domain scores for the individual guidelines show a wide variety: 'applicability' had on average the lowest mean score (53%) while 'scope and purpose' had the highest one (87%). Low scores indicate where improvements are possible and necessary, e.g. by providing more information about the development. Key experts in occupational health report that AGREE is a relevant and easy to use instrument to evaluate quality aspects and the included criteria provide a good framework to develop or update evidence-based practice guidelines in the field of occupational health.

Background Clinical practice guidelines are important for guiding practice, but it is unclear if they are commensurate with the available evidence. Methods We examined guidelines produced by cancer and gynecological societies and organizations and evaluated their coverage of and stance towards chemotherapy for advanced stage disease among 4 gynecological malignancies (breast, ovarian, cervical, endometrial cancer) where the evidence for the use of chemotherapy is very different (substantial and conclusive for breast and ovarian cancer, limited and suggesting no major benefit for cervical and endometrial cancer). Eligible societies and organizations were identified through systematic internet searches (last update June 2009). Pertinent websites were scrutinized for presence of clinical practice guidelines, and relative guidelines were analyzed. Results Among 224 identified eligible societies and organizations, 69 (31%) provided any sort of guidelines, while recommendations for chemotherapy on advanced stage gynecological malignancies were available in 20 of them. Only 14 had developed their own guideline, and only 5 had developed guidelines for all 4 malignancies. Use of levels of evidence and grades of recommendations, and aspects of the production, implementation, and timeliness of the guidelines did not differ significantly across malignancies. Guidelines on breast and ovarian cancer utilized significantly more randomized trials and meta-analyses. Guidelines differed across malignancies on their coverage of disease-free survival (p = 0.033), response rates (p = 0.024), symptoms relief (p = 0.005), quality of life (p = 0.001) and toxicity (p = 0.039), with breast and ovarian cancer guidelines typically covering more frequently these outcomes. All guidelines explicitly or implicitly endorsed the use of chemotherapy. Conclusions Clinical practice guidelines are provided by the minority of professional societies and organizations. Available guidelines tend to recommend chemotherapy even for diseases where the effect of chemotherapy is controversial and recommendations are based on scant evidence. PMID:21611154
