National Guideline Clearinghouse guideline syntheses and comparisons.

As the number of clinical practice guidelines relevant to clinical practice continues to grow, nurse practitioners may find it confusing to choose from two or more guidelines on the same or similar topics. The National Guideline Clearinghouse provides two resources to assist clinicians in comparing multiple guidelines on similar topics: guideline syntheses and guideline comparisons. This column describes the features of these two resources, using examples from guidelines on acute pharyngitis.

Developing evidence-based clinical guidelines for military use: case study of smoking cessation guidelines.

OBJECTIVE: To develop evidence-based clinical guidelines on smoking cessation, for use throughout the British military. METHOD: A ten-member, multiprofessional smoking cessation working group met five times between October 2000 and July 2001 to develop targeted smoking cessation guidelines for use by military health professionals in the clinical setting. The guidelines were based on the best available scientific evidence at that time, mainly systematic review of controlled trials, and individual randomised trials. RESULTS: The agreed military guidelines on smoking cessation were promulgated in July 2001. Three tiers of support were defined. Military health professionals have a key role as nonsmoking models and advocates, and should be trained to use 'brief intervention' at every clinical encounter with a military smoker. 'Intermediate support' (defined as a specialist service delivered by military health professionals who have undergone specific training and continuation training) is to be available at local level. The most heavily addicted military smokers will require referral to civilian smoking cessation clinics. Effective technologies for use at any one of the three levels of care are: nicotine skin patches, nicotine gum, nicotine lozenges and bupropion. CONCLUSIONS: These are the first ever clinical guidelines for military use which meet accepted modern quality criteria. Informal monitoring of the uptake of these guidelines between July 2001 to December 2001 suggests that they have been well received by military health professionals. An audit of their impact on smoking patterns within the UK Armed Forces will commence in 2002. The guidelines will be updated 5-yearly, or sooner.

Involvement of consumers in the development of evidence based clinical guidelines: practical experiences from the North of England evidence based guideline development programme.

BACKGROUND: Consumer involvement in clinical guidelines has long been advocated although there are few empirical accounts of attempts to do so. It is therefore not surprising that there is a lack of clarity about how and when to involve consumers and what to expect from them within the process of guideline development. METHODS: The North of England evidence based guideline development programme has used four different methods of consumer involvement. RESULTS: When individual patients were included in a guideline development group they contributed infrequently and had problems with the use of technical language. Although they contributed most in discussions of patient education, their contributions were not subsequently acted on. In a "one off" meeting with a group of patients there were again reported problems with medical terminology and the group were most interested in sections on patient education and self management. However, their understanding of the use of scientific evidence in order to contribute to a more cost effective health care remained unclear. In a workshop it was possible to explain the technical elements of guideline development to patients who could then engage with such a process and make relevant suggestions as a consequence. However, this was relatively resource intensive. A patient advocate within a guideline development group felt confidence to speak, was used to having discussions with health professionals, and was familiar with the medical terminology. CONCLUSIONS: Consumers should be involved in all stages of guideline development. While this is possible, it is not straightforward. There is no one right way to accomplish this and there is a clear need for further work on how best to achieve it.

Implementing practice guidelines: a workshop on guidelines dissemination and implementation with a focus on asthma and COPD.

The present supplement summarizes the proceedings of the symposium "Implementing practice guidelines: A workshop on guidelines dissemination and implementation with a focus on asthma and COPD", which took place in Quebec City, Quebec, from April 14 to 16, 2005. This international symposium was a joint initiative of the Laval University Office of Continuing Medical Education (Bureau de la Formation Médicale Continue), the Canadian Thoracic Society and the Canadian Network for Asthma Care, and was supported by many other organizations and by industrial partners. The objectives of this meeting were to examine the optimal implementation of practice guidelines, review current initiatives for the implementation of asthma and chronic obstructive pulmonary disease (COPD) guidelines in Canada and in the rest of the world, and develop an optimal strategy for future guideline implementation. An impressive group of scientists, physicians and other health care providers, as well as policy makers and representatives of patients' associations, the pharmaceutical industry, research and health networks, and communications specialists, conveyed their perspectives on how to achieve these goals. This important event provided a unique opportunity for all participants to discuss key issues in improving the care of patients with asthma and COPD. These two diseases are responsible for an enormous human and socioeconomic burden around the world. Many reports have indicated that current evidence-based guidelines are underused by physicians and others, and that there are many barriers to an effective translation of recommendations into day-to-day care. There is therefore a need to develop more effective ways to communicate key information to both caregivers and patients, and to promote appropriate health behaviours. This symposium contributed to the initiation of what could become the "Canadian Asthma and COPD Campaign", aimed at improving care and, hence, the quality of life of those suffering from these diseases. It is hoped that this event will be followed by other meetings that focus on how to improve the transfer of key recommendations from evidence-based guidelines into current care, and how to stimulate research to accomplish this.

Translating guidelines into practice. A systematic review of theoretic concepts, practical experience and research evidence in the adoption of clinical practice guidelines.

OBJECTIVE: To recommend effective strategies for implementing clinical practice guidelines (CPGs). DATA SOURCES: The Research and Development Resource Base in Continuing Medical Education, maintained by the University of Toronto, was searched, as was MEDLINE from January 1990 to June 1996, inclusive, with the use of the MeSH heading "practice guidelines" and relevant text words. STUDY SELECTION: Studies of CPG implementation strategies and reviews of such studies were selected. Randomized controlled trials and trials that objectively measured physicians' performance or health care outcomes were emphasized. DATA EXTRACTION: Articles were reviewed to determine the effect of various factors on the adoption of guidelines. DATA SYNTHESIS: The articles showed that CPG dissemination or implementation processes have mixed results. Variables that affect the adoption of guidelines include qualities of the guidelines, characteristics of the health care professional, characteristics of the practice setting, incentives, regulation and patient factors. Specific strategies fell into 2 categories: primary strategies involving mailing or publication of the actual guidelines and secondary interventional strategies to reinforce the guidelines. The interventions were shown to be weak (didactic, traditional continuing medical education and mailings), moderately effective (audit and feedback, especially concurrent, targeted to specific providers and delivered by peers or opinion leaders) and relatively strong (reminder systems, academic detailing and multiple interventions). CONCLUSIONS: The evidence shows serious deficiencies in the adoption of CPGs in practice. Future implementation strategies must overcome this failure through an understanding of the forces and variables influencing practice and through the use of methods that are practice- and community-based rather than didactic.

Development of evidence-based clinical practice guidelines for diabetes: the Department of Veterans Affairs/Department of Defense guidelines initiative.

OBJECTIVE: To describe the Veterans Affairs (VA)/Department of Defense (DoD) Clinical Practice Guidelines for diabetes and contrast selected recommendations with those of the American Diabetes Association (ADA). RESEARCH DESIGN AND METHODS: We summarize the general structure of the VA/DoD Guidelines and describe the rationale for recommendations issued in 2003 for glycemic control, management of hypertension, and retinopathy screening. We compare the synthesis of evidence and resulting recommendations for these content areas with the 2004 American Diabetes Association Clinical Practice Recommendations. RESULTS: The VA/DoD Guidelines and the ADA Clinical Practice Recommendations reported similar strength of evidence findings by content area, but clinical recommendations varied. The VA/DoD Guidelines and practice recommendations emphasize the use of data on absolute risk reduction from available published randomized clinical trials rather than relative risk reduction from observational analyses. The VA/DoD Guidelines employ an algorithm-based methodology to guide clinicians through a risk-stratified approach to managing individual patients rather than promoting a single standard for most or all patients without explicit consideration of competing comorbidities. CONCLUSIONS: The VA/DoD Guidelines are intended to guide diabetes care by providing Internet-ready, evidence-based annotations in algorithmic form to help clinicians set and revise individual treatment goals for their patients.

Erythropoietin use in oncology: a summary of the evidence and practice guidelines comparing efforts of the Cochrane Review group and Blue Cross/Blue Shield to set up the ASCO/ASH guidelines.

Clinical research evidence on outcomes of using epoetin (EPO) to treat or prevent anemia in oncology has recently been systematically synthesized to provide a scientific foundation for developing and implementing clinical practice guidelines. Two groups have distinguished themselves by their meticulous research methods, the Blue Cross and Blue Shield Association Technology Evaluation Center (BCBSA TEC) and the Cochrane Review Group (CRG), and have summarized existing research evidence on the role of EPO in anemia associated with cancer treatment. An ASH/ASCO (American Society of Hematology/American Society of Clinical Oncology) panel has used the BCBSA TEC review to develop practice guidelines on the use of EPO in patients with cancer. The ASH/ASCO guideline panel identified eight important clinical circumstances for which use of EPO in oncology might be considered and used the BCBSA TEC evidence review to formulate evidence-based guidelines that support use of EPO. Both BCBSA TEC and CRG found solid evidence exists to show that EPO improves hemoglobin levels and reduce the risk for transfusion. The ASH/ASCO panel concluded that best empirical evidence exists to support the use of EPO to correct anemia due to chemotherapy if Hgb</=10g/dl. In other clinical circumstances the ASH/ASCO panel made recommendations either by extrapolating evidence from similar settings or relied on expert opinion since sufficient evidence was lacking. Both BCBSA TEC and CRG also concluded that limited evidence exists that EPO improves symptoms, fatigue, or quality of life, particularly when anemia is less severe. The finding from these systematic reviews are also reflected in the opinion of the ASH/ASCO guidelines panel, which also concluded that better evidence is needed to support use of EPO in oncology under these circumstances. In this paper, the findings from the guidelines set by ASH/ASCO that were culled from systematic reviews by BCBSA TEC and the Cochrane Review are compared and contrasted.

Taking the national guideline for care of acute myocardial infarction to the bedside: developing the guideline applied in practice (GAP) initiative in Southeast Michigan.

BACKGROUND: The Guideline Applied in Practice (GAP) program was developed in 2000 to improve the quality of care by improving adherence to clinical practice guidelines. For the first GAP project, the American College of Cardiology (ACC) partnered with the Southeast Michigan Quality Forum Cardiovascular Subgroup and the Michigan Peer Review Organization (MPRO) to develop interventions that might facilitate the use of the ACC/AHA Acute Myocardial Infarction (AMI) guideline in the practice setting. Ten Michigan hospitals participated in implementing the project, which began in March 2000. DESIGNING THE PROJECT: The project developed a multifaceted intervention aimed at key players in the care delivery triangle: the physician, nurse, and patient. Intervention components included a project kick-off presentation and dinner, creation and implementation of a customized tool kit, identification and assignment of local nurse and physician opinion leaders, grand rounds site visits, and measurement before and after the intervention. IMPLEMENTING THE PROJECT: The GAP project experience suggests that hospitals are enthusiastic about partnering with ACC to improve quality of care; partners can work together to develop a program for guideline implementation; rapid-cycle implementation is possible with the GAP model; guidelines and quality indicators for AMI are well accepted; and hospitals can adapt the national guideline for care into usable tools focused on physicians, nurses, and patients. DISCUSSION: Important structure and process changes--both of which are required for successful QI efforts--have been demonstrated in this project. Ultimately, the failure or success of this initiative will depend on an indication that the demonstrated improvement in the quality indicators is sustained over time.

A method for guideline development: assessing practical feasibility and adaptation of thyroid nodule guidelines.

The objective of this study was to assess adaptation and feasibility of practice guidelines for thyroid nodule management. For one month physicians completed a self-administered semi-structured questionnaire concerning a draft version of the guidelines for each consecutive patient. A sample group of 20 endocrinologists, 20 surgeons and 120 general practitioners from all parts of France took part in this study. The main outcome measures were whether the case description was found by the physicians, and whether recommendations were found and agreement with these recommendations were assessed. We found that two hundred and fifty-three patients (of whom 85% were women) were included in the study: 52% were seen for a surgical decision; 20% for diagnosis or screening and 28% for follow-up. Four percent of the women were pregnant; 2% of the patients had a large nodule; and 2%, a retrosternal nodule. These last three situations had not been well identified in the draft guidelines. The patient's case description was appropriately identified in 75% of the responses. Most cases reported as being not found were, however, covered by the guidelines. Physicians in private practice were less likely than the others to identify their patient's cases. Physicians agreed with the recommendation in 77% of cases. General practitioners were more likely and endocrinologists less likely than surgeons to disagree. Most disagreements and alternative proposals were not evidence-based. Our conclusion is that this study shows that the draft guidelines were applicable, and allowed minor improvements of the final version. Adapting guidelines to practice could improve their use and, consequently, the quality of health care.

Auditing the implementation of SIGN (Scottish Intercollegiate Guidelines Network) clinical guidelines.

Clinical practice guidelines are increasingly being recognised as integral to the clinical effectiveness agenda. According to the recent Scottish White Paper, Scotland "leads the way in clinical effectiveness". The Scottish Intercollegiate Guidelines Network (SIGN), established in 1993, has produced over 20 clinical practice guidelines, and plans to produce at least as many more, while reviewing existing guidelines at a minimum of every two years. This represents a substantial investment of NHS resources. This paper investigates whether this investment is being recouped in Scottish NHS acute trusts via the implementation of SIGN guidelines, and whether their implementation is being audited properly. It is argued that without clinical audit, guideline implementation is unlikely to succeed. This has important ramifications for the implementation of clinical governance.

Including practice data to improve evidence-based guidelines. Example of guidelines on the management of thyroid nodules.

Although clinical guidelines are based on the best evidence available, their proliferation has often failed to change actual practice. One of the many explanations suggested is that there is a gap between the expectations of the targeted professionals and the recommendations in the guidelines. In this study, we attempted to take into account the state of current practice and the physicians' priorities. Using the example of guidelines on the management of thyroid nodules, three different surveys have been conducted: (1) an analysis of physicians' expectations and practice through a postal questionnaire to define appropriate questions; (2) a survey of the professionals' expert opinions, and (3) a prospective study of the use of these guidelines in the management of 253 patients. The results of these surveys have modified the development of the guidelines, and helped us to adapt the content of the guidelines to match physicians' practices more closely.

[The Cologne Guidelines Conference: computer-assisted clinical practice guidelines in clinical diagnosis].

Eighteen clinical practice guidelines on interdisciplinary diagnostic issues were developed at the University Hospital of Cologne, Germany. The guideline committee is organized and directed by the quality control program, which also includes the local Cochrane initiative and a wide range of organizational topics. During guideline development, questions of differential diagnosis were addressed to the same extent as the organizational and financial realization. Broad consideration was given to medicolegal implications, but need for interspecialty cooperation was judged to be more critical and even more relevant in this regard. Guidelines were primarily developed as algorithms and translated to text versions secondarily. Critical steps in the decision tree were supported by rated literature and recommendations weighte by criteria as used in evidence-based medicine. For implementation, guidelines were presented to colleagues in a series of short lectures, as print versions containing all literature used in the developing process, and in hypertext format, which is accessible via intranet. Three levels of presentation were chosen in the html-version: algorithm, decision, and information. The former is due to orientation in the guideline, the second displays the binary question, and the latter makes the scientific background available, together with literature and links for more information. Efforts to check effectiveness are currently been made, questions of efficiency will be addressed in future.

Preparing strategic information management plans for hospitals: a practical guideline SIM plans for hospitals: a guideline.

OBJECTIVES: Systematic information management in hospitals demands for a strategic information management plan (SIM plan). As preparing a SIM plan is a considerable challenge we provide a practical guideline that is directly applicable when a SIM plan is going to be prepared. METHODS: The guideline recommends a detailed structure of a SIM plan and gives advice about its content and the preparation process. It may be used as template, which can be adapted to the individual demands of any hospital. RESULTS: The guideline was used in several hospitals preparing a SIM plan. Experiences showed that the SIM plans could be prepared very efficiently and timely using the guideline, that the proposed SIM plan structure suited well, that the guideline offers enough flexibility to meet the requirements of the individual hospitals and that the specific recommendations of the guideline were very helpful. CONCLUSIONS: Nevertheless, we must strive for a more comprehensive theory of strategic information management planning which -- in the sense of enterprise architecture planning -- represents the intrinsic correlations of the different parts of a SIM plan to a greater extent.

Keeping cancer guidelines current: results of a comprehensive prospective literature monitoring strategy for twenty clinical practice guidelines.

OBJECTIVES: To describe a methodology used to keep practice guidelines up to date and to summarize data collected during the first year of implementing this plan with a cancer practice guidelines program. METHODS: The updating strategy includes regular searches of peer-reviewed literature and meeting proceedings, review and interpretation of new evidence, review and revision of clinical recommendations, and notification to practitioners and policy makers about new evidence and its impact on recommendations. RESULTS: Eighty pieces of new evidence were found relating to seventeen of the twenty guidelines included in this study. On average, four pieces of new evidence were found per guideline, but there was considerable variation across the guidelines. Of the eighty pieces, nineteen contributed to modifications of clinical recommendations in six practice guidelines, whereas the remaining evidence served to support the original recommendations. None of the modifications led to changes that advised against original recommendations. MEDLINE, the Cochrane Library, and meeting proceedings yielded many pieces of evidence, whereas CancerLit and HealthStar did not contribute significantly to the overall yield. Furthermore, key pieces of evidence that led to modifications to the recommendations were often identified by members of the disease site groups before appearing in electronic databases. CONCLUSIONS: The updating process is resource intensive but yields important findings. In response to this evaluation, the updating protocol has been revised such that literature searches are conducted quarterly and the scope of sources searched routinely is restricted to MEDLINE, the Cochrane Library, and meeting proceedings.

Internists' evaluation of guidelines: the IMCARE Practice Guidelines Network.

This paper presents the attitudes and experiences of one group of practicing internists, the IMCARE Practice Guidelines Network, with clinical practice guidelines. From its beginning the Network has enjoyed close ties to both the Agency for Health Care Policy and Research (AHCPR) and the Institute of Medicine (IOM) with their guideline mandates. The Network is a self-selected group of 471 internists and their subspecialty colleagues, dispersed throughout the U.S. Network member evaluations of draft clinical practice guidelines present a compelling case for the need for clarity of language and a more condensed guideline structure. As Network members' critique indicates, once published, guidelines have become communication tools.

Translating practice guidelines into patient care : guidelines at the bedside.

Practice guidelines have been developed by a myriad of government, subspecialty, and local organizations in an attempt to reduce undesirable variations in care and to improve the quality of care. Despite the current enthusiasm driving the creation of thousands and thousands of guidelines, their longevity will depend on the ability to demonstrate measurable improvements in patient care caused by the dissemination and implementation of guidelines. In order for guidelines to improve care, they must influence the decisions that physicians and other health-care providers make as they care for patients on a day-to-day basis. Studies on this topic show that some guideline implementation strategies are consistently effective, meaning that they lead to changes in care that benefit patients. Other strategies have been shown to be consistently ineffective. Using an evidence-based approach to selecting guideline dissemination and implementation strategies may facilitate the greatest chance of success, and enhance the probability that patient care will be meaningfully improved as a result of these efforts.

Validation of an XML-based process to automatically web-enable clinical practice guidelines: experience with the smoking cessation guideline.

OBJECTIVES: To validate the ease by which a Clinical Practice Guideline (CPG) can be web-enabled using an XML-based semi-automated process. DESIGN AND IMPLEMENTATION: An XML DTD for Clinical Practice Guidelines and an MS Word authoring template were created in an earlier project. We took an existing guideline, Bedside Smoking Cessation Intervention, placed it into the MS Word template, converted it into XML, and then to HTML for deployment over the Kaiser Permanent intranet. CONCLUSIONS: We were able to use the MS Word authoring template and automatically generate both an XML representation of our guideline, and an HTML representation, which we have deployed on our intranet. The Bedside Smoking Cessation Intervention guideline was automatically merged into the online guidelines collection. Placing it on our intranet allowed for rapid and easy access by physicians and other health care providers throughout the Kaiser Permanente Medical Care Program.

A preliminary evaluation of guideline content mark-up using GEM--an XML guideline elements model.

OBJECTIVE: To describe application of GEM to analysis and categorization of guideline content. METHOD: We examined the application of GEM constructs to the AAP guideline on neurodiagnostic evaluation of febrile seizures. Subjects at 4 sites marked-up the guideline content using a hierarchical template that includes branches for identity, developer, purpose, intended audience, method of development, knowledge components, testing, and review. The types of elements used were tabulated. Subjects were surveyed regarding the usability of the model. RESULTS: Eight subjects analyzed the guideline, using between 46 and 149 elements to model its content. There was considerable variation in the application of elements. The number of elements used correlated with time to complete the task. Subjects found application of GEM to be straightforward in 6 of 8 categories and sufficiently comprehensive to model the guideline's information content. CONCLUSIONS: Subjects found GEM constructs were able to model the content of the guideline. Improved editing tools will facilitate translation.
