Role of guidelines in clinical practice for the management of HIV-related diseases.

Several guidelines have been developed for the diagnosis, treatment and prevention of infectious diseases. Actually, evidence-based clinical practice guidelines provide physicians and other health care professionals with scientific information about the most appropriate strategy for the management of these patients, in order to avoid unnecessary or inappropriate interventions. As medical technology rapidly increases and becomes more complex, clinical guidelines can help health care providers to assess current practices and integrate new technological advances. Since AIDS was first recognized nearly 20 years ago, remarkable progress has been made in improving the quality and duration of life for HIV+ patients. In this area, clinical guidelines have been developed to manage patient care, focusing on: antiretroviral therapy, prevention of opportunistic infections, and treatment of tuberculosis. The quality of the guideline is notable when appropriate methodologies are applied. Different methods for developing guidelines are evaluated here: Agency for Health Care Policy and Research (AHPCR) methodology is designed to produce evidence-based guidelines that are valid, clinically applicable, and flexible. Finally, the problems associated with the implementation of guidelines for HIV-related diseases and other infectious diseases are examined.

Do clinical guidelines improve general practice management and referral of infertile couples?

OBJECTIVE: To evaluate guidelines for general practice management and referral of infertile couples. Guidelines were implemented with a disease specific reminder at the time of consultation (the guidelines were embedded within a structured infertility management sheet for each couple). DESIGN: Pragmatic randomised controlled trial. Participating practices were randomised to a group that received the guidelines and a control group. SETTING: 82 general practices in Grampian region. SUBJECTS: 100 couples referred by general practitioners receiving the guideline and 100 couples referred by control general practitioners. MAIN OUTCOME MEASURES: Whether the general practitioner had taken a full sexual history and examined and investigated both partners appropriately. RESULTS: Characteristics of patients referred by study and control general practitioners did not differ significantly at baseline. Compliance with the guidelines increased for all targeted activities. General practitioners in the study group were more likely to take a sexual history (for example, couples' use of fertile period, 85% v 69%, p < 0.01); examine both partners (female partner, 68% v 52%, p < 0.05; male partner 39% v 13%, p < 0.01); and investigate both partners (day 21 progesterone, 72% v 41%, p < 0.001; semen analysis, 51% v 41%, p > 0.05). Improvements were greater when general practitioners used the disease specific reminder. CONCLUSION: Receiving guidelines led to improvements in the process of care of infertile couples within general practice. This effect was enhanced when the guidelines were embedded in a structured infertility management sheet for each couple.

Understanding variation in rates of referral among general practitioners: are inappropriate referrals important and would guidelines help to reduce rates?

OBJECTIVES: To determine the extent to which variation in rates of referral among general practitioners may be explained by inappropriate referrals and to estimate the effect of implementing referral guidelines. SETTING: Practices within Cambridge Health Authority and Addenbrooke's Hospital, Cambridge. MAIN OUTCOME MEASURES: Data on practice referral rates from hospital computers, inappropriate referrals as judged by hospital consultants, and inappropriate referrals as judged against referral guidelines which had been developed locally between general practitioners and specialists. Effect of referral guidelines on referral patterns as judged by general practitioners using the guidelines in clinical practice. RESULTS: There was 2.5-fold variation in referral rates among general practices. According to the specialists, 9.6% (95% confidence interval 6.4% to 12.9%) of referrals by general practitioners and 8.9% (2.6% to 15.2%) of referrals from other specialists were judged possibly or definitely inappropriate. Against locally determined referral guidelines 15.9% of referrals by general practitioners were judged possibly inappropriate (11.8% to 20.0%). Elimination of all possibly inappropriate referrals could reduce variation in practice referral rates only from 2.5-fold to 2.1-fold. An estimate of the effect of using referral guidelines for 60 common conditions in routine general practice suggested that application of guidelines would have been unlikely to reduce rates of referral in hospital (95% confidence interval -4.5% to 8.6% of consultations resulting in referral). CONCLUSION: The variation in referral rates among general practitioners in Cambridge could not be explained by inappropriate referrals. Application of referral guidelines would be unlikely to reduce the number of patients referred to hospital.

What constitutes controlled hypertension? Patient based comparison of hypertension guidelines.

OBJECTIVES: To investigate and quantify the extent to which variations in guidelines influence assessment of control of hypertension. DESIGN: Cross sectional study. Selected patients had hypertension assessed as controlled or uncontrolled with guidelines from New Zealand, Canada, the United States, Britain, and the World Health Organisation. SETTING: 18 general practices in Oxfordshire. SUBJECTS: 876 patients with diagnosed hypertension and taking antihypertensive drugs. MAIN OUTCOME MEASURES: Proportion of patients with controlled hypertension according to each set of guidelines. RESULTS: The proportion of patients with controlled hypertension varied from 17.5% to 84.6% with the different guidelines after adjustment for the sampling method. All five sets of guidelines agreed on the classification for 31% (277) of the patients. The New Zealand guidelines calculate an absolute risk of a cardiovascular event. When this was taken as the standard half of the patients with uncontrolled hypertension by the United States criteria would be treated unnecessarily and 31% of those classified as having controlled hypertension by the Canadian guidelines would be denied beneficial treatment. CONCLUSIONS: Hypertension guidelines are inconsistent in their recommendations and need to make clear the absolute benefits and risks of treatment.

Representing clinical guidelines in GLIF: individual and collaborative expertise.

OBJECTIVE: An evaluation of the cognitive processes used in the translation of a clinical guideline from text into an encoded form so that it can be shared among medical institutions. DESIGN: A comparative study at three sites regarding the generation of individual and collaborative representations of a guideline for the management of encephalopathy using the GuideLine Interchange Format (GLIF) developed by members of the InterMed Collaboratory. MEASUREMENTS: Using theories and methods of cognitive science, the study involves a detailed analysis of the cognitive processes used in generating representations in GLIF. The resulting process-outcome measures are used to compare subjects with various types of computer science or clinical expertise and from different institutions. RESULTS: Consistent with prior studies of text comprehension and expertise, the variability in strategies was found to be dependent on the degree of prior experience and knowledge of the domain. Differing both in content and structure, the representations developed by physicians were found to have additional information and organization not explicitly stated in the guidelines, reflecting the physicians' understanding of the underlying pathophysiology. The computer scientists developed more literal representations of the guidelines; addition were mostly limited to specifications mandated by the logic of GLIF itself. Collaboration between physicians and computer scientists resulted in consistent representations that were more than the sum of the separate parts, in that both domain-specific knowledge of medicine and generic knowledge of guideline structure were seamlessly integrated. CONCLUSION: Because of the variable construction of guideline representations, understanding the processes and limitations involved in their generation is important in developing strategies to construct shared representations that are both accurate and efficient. The encoded guidelines developed by teams that include both clinicians and experts in computer-based representations are preferable to those developed by individuals of either type working alone.

Clinical guidelines: proliferation and medicolegal significance.

Guidelines seeking to influence and regulate clinical activity are currently gaining a new cultural ascendancy on both sides of the Atlantic. Statutory agencies may be charged with developing clinical guidelines, and civil courts, in deciding actions in negligence, could be influenced by standards of care expressed in guideline statements. Clinical guidelines are not accorded unchallengeable status: they have been subject to careful scrutiny by British and American courts to establish their authenticity and relevance. In the United States, compliance with clinical guidelines cannot be used as a defence against liability if a physician's conduct is held to have been negligent, and third party organisations can be held liable if their clinical guidelines are found to be a contributory cause of patient harm. Guidelines have not usurped the role of the expert witness in court. The importance the law attaches to customary practice means that atypical or bizarre guidelines are unlikely to be accepted as embodying a legally required standard of clinical care.

Non-compliance with national guidelines in the management of acute pancreatitis in the United kingdom.

BACKGROUND: Deficiencies and lack of standardisation of the management of acute pancreatitis in the UK have been reported. National UK guidelines for the management of acute pancreatitis were published in 1998. However, implementation of national guidelines in other areas has been patchy, suggesting that evaluation of the uptake of the pancreatitis guidelines would be appropriate. AIM: Identification of current practice in the management of acute pancreatitis as reported by consultant surgeons, in order to determine how effectively the UK guidelines have been introduced into practice. METHODS: A questionnaire was posted to 1,072 full members of the Association of Surgeons of Great Britain and Ireland. It consisted of 13 questions that aimed to identify the surgeon's practice in the management of patients with acute pancreatitis in relation to key points in the UK guidelines. We compared the practice of hepatobiliary and pancreatic (HBP) vs. non-HBP specialists, and teaching vs. non-teaching hospital surgeons using the chi(2) test. RESULTS: Of 538 responses (50%), 519 were from consultant surgeons. 59 did not look after patients with acute pancreatitis and 89 (17%) had a HBP interest. There were differences between the recommendations in the guidelines and reported practice, particularly in the use of critical care resources and referral to specialist units. Of consultants looking after acute pancreatitis 371 (72%) were non-HBP specialists. There were significant overall differences between the practice of HBP specialists and non-specialists: in severity assessment (Glasgow and C-reactive protein vs. Ranson criteria); indication and timing of requesting computed tomography (routinely at 7-10 days vs. when clinically indicated); nutritional support (enteral feeding vs. no support), and in common bile duct assessment prior to cholecystectomy (intra-operative cholangiography vs. endoscopic retrograde cholangiopancreatography). There was no significant difference between practice in teaching and non-teaching hospitals. CONCLUSION: Implementation of national guidelines for the management of acute pancreatitis was greater in the practice of HBP specialists than non-specialists. This has implications for the rationale of creating guidelines, and for the strategies associated with their introduction.

A review of the treatment guidelines on the management of low levels of high-density lipoprotein cholesterol.

This paper aims to review the guidelines on the importance given to high-density lipoprotein cholesterol (HDL-C) as a risk factor or as threshold and target level in the treatment of dyslipidemia. We developed a strategy with cholesterol-related key words to search for guidelines in the major databases. The Appraisal of Guidelines Research Evaluation (AGREE) instrument was used for the evaluation and inclusion of the guidelines. In total nine guidelines were selected. Almost all selected guidelines consider low HDL-C as a marker of an increased risk for coronary heart disease. However, only few guidelines use the level of HDL-C as a threshold or target level for the treatment of dyslipidemia. The guidelines provide only little information on the management of patients with treatment-induced low HDL-C. Instead of using total cholesterol (TC) or low-density lipoprotein cholesterol (LDL-C) we consider the use of the ratios of TC to HDL-C or LDL-C to HDL-C as a threshold as well as a target for treatment.

The impact of unstable angina guidelines in the triage of emergency department patients with possible acute coronary syndrome.

OBJECTIVE: The primary aim of this study is to determine whether implementing the Agency for Health Care Policy and Research (AHCPR) Unstable Angina Practice Guideline improves emergency physician's decision making in patients with symptoms of possible acute coronary syndrome (ACS), including those for whom the diagnosis of unstable angina is uncertain. METHODS: The authors conducted a prospective guideline implementation trial with pre-post design in the emergency departments of 1 university hospital and 1 university-affiliated community teaching hospital from January 2000 to May 2001. They enrolled 1140 adults who presented with chest pain or other symptoms of possible ACS. The intervention included the following: 1) physician training in use of the AHCPR risk groups, 2) algorithm for risk stratification, and 3) group feedback. To determine how accurately physicians interpreted the guideline algorithm, the authors compared their risk ratings with actual guideline risk groups. RESULTS: No significant difference in physician triage decisions was observed between baseline and intervention periods. Analysis of physician's risk ratings during the intervention period revealed low overall concordance with actual guideline risk groups (kappa = 0.31); however, physician's risk ratings showed superior discrimination in identifying patients with confirmed ACS (receiver operating characteristic [ROC] area .81 v. .74, P = 0.008). Strict adherence to guideline recommendations would have resulted in hospitalizing 9% more non-ACS patients without lowering the rate of missed ACS. CONCLUSION: Implementation of the AHCPR guideline did not improve triage decisions in emergency department patients with possible ACS. Assessing physician triage solely based on concordance with the AHCPR guideline may not accurately reflect the quality of patient care.

Relationship between guideline treatment and health-related quality of life in asthma.

The aim of this study was to compare the health-related quality of life (HRQL) of asthma patients treated according to the 1997 National Institute of Health (NIH) international asthma guideline and that of asthmatics receiving non-guideline treatment. The suitability of 146 asthmatics' medication regimes was determined according to the 1997 NIH asthma guideline. Quality of life was assessed on a seven-point scale using the Asthma Quality of Life questionnaire. Just over half of the patients were not currently using the treatment considered necessary for controlling their asthma. Patients treated according to the guideline (n=72) had a significantly higher overall HRQL than patients with non-guideline treatment (5.7 versus 5.3). The differences were also significant for the subscales measuring symptoms and environmental exposure, but not for activities or emotional function. An association between non-guideline treatment and a poorer health-related quality of life in asthma patients treated in general practice was observed. This study supports the role of evidence-based guidelines in daily practice. Further studies are needed to determine if guideline treatment is responsible for the increase in health-related quality of life observed in this work.

Clinical guidelines.

Clinical guidelines are likely to be an important part of medical practice for the foreseeable future. Guidelines at their best are tools for consistency and effectiveness in patient care. Guideline methodology has evolved such that there are internationally agreed standards with which to develop and assess guidelines. Guideline development groups should ideally be multidisciplinary in composition and if possible have patient representation. Key to the process is the rigour of the systematic review in order to assess the best evidence on which to base recommendations. Guideline recommendations should be explicitly linked to the evidence. In order to safeguard trust, guideline development groups must have editorial independence of government, industry and special interest groups, while at the same time having regard to the implications of their recommendations. Implementation of guidelines by passive dissemination is largely ineffective; effective dissemination requires an imaginative approach tailored to the intended audience.

US physicians' perceptions of the effect of practice guidelines and ability to provide high-quality care.

OBJECTIVES: In the USA, health care organizations frequently disseminate practice guidelines to physicians, but physicians often resist implementing guidelines when they perceive no improvements in quality of care will result. Greater involvement with a single health care organization may a inverted exclamation market physicians' perceptions of guidelines. We examined the relationship between the perceived effect of guidelines on practice and perceived quality of care for US primary care physicians (PCPs) and specialists with varying levels of financial involvement with a single managed care organization. METHODS: Data were from the 1996-1997 Community Tracking Study, a nationally representative, cross-sectional survey of 12,528 physicians. Data were adjusted for possible confounders using ordinal logistic regression. RESULTS: Almost half the physicians described a moderate to very large perceived effect of guidelines (46% of PCPs, 46% of specialists). Physicians' financial involvement with a single organization was modest: PCPs received on average 24% of their revenue from their largest contract, while specialists averaged 18%. For specialists, increasing perceived effect of guidelines was associated with increasingly negative perceptions of quality of care [beta= -0.16, 95% confidence interval (-0.22, -0.10)]. Similar results were obtained for PCPs with low levels of financial involvement with a single organization. However, this negative association disappeared for PCPs with higher levels of financial involvement. CONCLUSIONS: PCPs with substantial financial involvement with a single organization who perceive greater effects of guidelines on practice have less negative perceptions of their ability to provide high-quality care. Although our data cannot confirm a causal relationship, financial involvement with a single organization may be one factor linking practice guidelines to high-quality care.

Explanations and unresolved issues pertaining to the development of the Nuclear Pharmacy Compounding Guidelines.

OBJECTIVES: To provide background information related to the development of the Nuclear Pharmacy Compounding Guidelines, to discuss regulatory complexities related to radiopharmaceutical compounding practice, and to summarize the gaps in the current compounding regulations for radiopharmaceuticals. DATA SOURCES: The Guidelines closely follow the provisions of section 503A of the Federal Food, Drug, and Cosmetic Act (FD&C Act), the monographs and chapters related to pharmacy compounding in the United States Pharmacopeia (USP), and the recommended guidelines published by the American Society of Health-System Pharmacists. SUMMARY: The Food and Drug Administration Modernization Act (FDAMA) of 1997 established parameters under which the compounding of drug products is appropriate and lawful, but these criteria expressly do not apply to radiopharmaceuticals. The Nuclear Pharmacy Compounding Practice Committee, a group of nuclear pharmacists convened by the American Pharmaceutical Association, developed the Nuclear Pharmacy Compounding Guidelines to establish a set of principles and guidelines for good radiopharmaceutical compounding practice. The intent of the new document is to provide guidance on radiopharmaceutical compounding practices that have evolved over the last 2 decades and to place them in an appropriate regulatory framework in accordance with previous enforcement policies and guidelines issued by the U.S. Food and Drug Administration (FDA) regarding the exemption of certain pharmacy practices from enforcement of adulteration, misbranding, and new drug requirements. CONCLUSION: The Nuclear Pharmacy Compounding Guidelines, recently released by APhA, is the first official document that provides realistic and practical compounding guidance for nuclear pharmacists. Even though the United States Court of Appeals for the Ninth Circuit recently ruled section 503A of the FD&C Act to be invalid in its entirety, and the Supreme Court upheld that ruling, the compliance policy guides issued by FDA in March 1992 and revised in May 2002 maintain guiding principles on pharmacy compounding similar to those stated in section 503A of the FD&C Act. The Nuclear Pharmacy Compounding Practice Committee is optimistic that the practical information contained in the Guidelines will assist state boards of pharmacy, FDA, and the United States Pharmacopeial Convention in setting appropriate standards for nuclear pharmacy compounding practice that will ensure the continued availability of high-quality compounded radiopharmaceuticals at reasonable cost.

New recommendations from the 1999 American College of Cardiology/American Heart Association acute myocardial infarction guidelines.

OBJECTIVE: To review literature relating to significant changes in drug therapy recommendations in the 1999 American College of Cardiology (ACC)/American Heart Association (AHA) guidelines for treating patients with acute myocardial infarction (AMI). DATA SOURCES: 1999 ACC/AHA AMI guidelines, English-language clinical trials, reviews, and editorials researching the role of drug therapy and primary angioplasty for AMI that were referenced in the guidelines were included. Additional data published in 2000 or unpublished were also included if relevant to interpretation of the guidelines. STUDY SELECTION: The articles selected influence AMI treatment recommendations. DATA SYNTHESIS: Many clinicians and health systems use the ACC/AHA AMI guidelines to develop treatment plans for AMI patients. This review highlights important changes in AMI drug therapy recommendations by reviewing the results of recent clinical trials. Insights into evolving drug therapy strategies that may impact future guideline development are also described. CONCLUSIONS: Several changes in drug therapy recommendations were included in the 1999 AMI ACC/AHA guidelines. There is emphasis on administering fibrin-specific thrombolytics secondary to enhanced efficacy. Selection between fibrin-specific agents is unclear at this time. Low response rates to thrombolytics have been noted in the elderly, women, patients with heart failure, and those showing left bundle-branch block on the electrocardiogram. These patient groups should be targeted for improved utilization programs. The use of glycoprotein (GP) IIb/IIIa receptor inhibitors in non-ST-segment elevation MI was emphasized. Small trials combining reduced doses of thrombolytics with GP IIb/IIIa receptor inhibitors have shown promise by increasing reperfusion rates without increasing bleeding risk, but firm conclusions cannot be made until the results of larger trials are known. Primary percutaneous coronary intervention (PCI) trials suggest lower mortality rates for primary PCI when compared with thrombolysis alone. However, primary PCI, including coronary angioplasty, is only available at approximately 13% of US hospitals, making thrombolysis the preferred strategy for most patients. Clopidogrel has supplanted ticlopidine as the recommended antiplatelet agent for patients with aspirin allergy or intolerance following reports of a better safety profile. The recommended dose of unfractionated heparin is lower than previously recommended, necessitating a separate nomogram for patients with acute coronary syndromes. Routine use of warfarin, either alone or in combination with aspirin, is not supported by clinical trials; however, warfarin remains a choice for antithrombotic therapy in patients intolerant to aspirin. Beta-adrenergic receptor blockers continue to be recommended, and emphasis is placed on improving rates of early administration (during hospitalization), even in patients with moderate left ventricular dysfunction. New recommendations for drug treatment of post-AMI patients with low high-density lipoprotein cholesterol and/or elevated triglycerides are included, with either niacin or gemfibrozil recommended as an option. Supplementary antioxidants are not recommended for either primary or secondary prevention of AMI, with new data demonstrating lack of efficacy vitamin E in primary prevention. Estrogen replacement therapy or hormonal replacement therapy should not be initiated solely for prevention of cardiovascular disease, but can be continued in cardiovascular patients already taking long-term therapy for other reasons. Bupropion has been added as a new treatment option for smoking cessation. As drug therapy continues to evolve in treating AMI, more frequent updates of therapy guidelines will be necessary.

Impact of prescribing guidelines for inpatient anticoagulation.

BACKGROUND: Anticoagulants are widely used and represent a class of drugs that are problem-prone and have a high potential for adverse patient outcomes. As such, these drugs may be amenable to the use of prescribing guidelines. However, relatively little has been published on the effect of such guidelines on clinical outcomes or costs of care. OBJECTIVE: To assess whether guidelines improve the appropriateness of prescribing, clinical outcomes, and costs associated with use of anticoagulants in a sample of community hospitals in the US. METHODS: A retrospective analysis was performed of data voluntarily collected by 15 hospitals before (July-September 2001) and after (March-May 2002) implementation of anticoagulant prescribing guidelines. Statistical analyses of both patient- and hospital-level variables were conducted. RESULTS: Implementation of the guidelines resulted in a significant increase in the proportion of anticoagulants that were prescribed appropriately (59.8% vs 86.9%; p < 0.001). The guidelines also resulted in a shift in the type of anticoagulants prescribed (decreased use of unfractionated heparin and increased use of low-molecular-weight heparins). There was suggestive evidence, although not statistically significant, that the guidelines resulted in fewer anticoagulant-associated adverse events (total bleeding RR 0.71) and lower costs (savings of $56.15 per patient per day). CONCLUSIONS: While limitations existed with the study design, sufficient benefits were identified to warrant hospitals to consider use of these or similar guidelines on a routine basis. Clearly, additional study in this area would be useful.

Adherence to established guidelines for preoperative pulmonary function testing.

Guidelines for ordering preoperative spirometry have been proposed by GM Tisi (1979) and more recently by the American College of Physicians (ACP). Requests for preoperative spirometries represent a significant portion of all requests for screening spirometry at our institution and utilize significant man-hours of technician time. We determined the percentage of these requests that did not meet the ACP guidelines and characterized why these requests were being generated. We sampled 441 screening spirometries performed by the Walter Reed Pulmonary Function Laboratory over a 4-week period. One hundred thirty-eight (31%) of these were done preoperatively and complete data were available in 135 cases. Patients in the analyzed group had a mean age of 59 years (+/- 14 years), ranging from 20 to 84 years of age. Fifty-two (39%) requests did not meet ACP guidelines. Most of these requests were associated with either normal spirometry (n = 34) or only mild spirometric abnormalities (n = 14). Spirometry revealed severe obstruction in only one case when the request was not indicated. No cases of moderate obstruction, severe restrictive pattern, or possible upper airway obstruction were found in the group of requests in which spirometry was not indicated. Of the requests that did not meet ACP guidelines, 21 met Tisi's broader guidelines. Most of these requests were found exclusively in patients older than 70 years of age (n = 13) and the morbidly obese (n = 4). Of the 31 studies that did not meet either set of guidelines, 25 occurred in asymptomatic, current, or prior smokers. In conclusion, during a 4-week study period at our institution, 39% of preoperative spirometry requests did not meet ACP guidelines. Most of the patients had been referred because of age greater than 70 years, morbid obesity, and a current/prior history of smoking. However, the literature does not support obtaining preoperative spirometry in such patients except for those undergoing only lung resection. We recommend stricter adherence to the ACP guidelines as a means of decreasing the number and cost of unnecessary spirometries being performed.

Reducing length of stay for patients hospitalized with exacerbation of COPD by using a practice guideline.

UNLABELLED: Clinical practice guidelines have been promoted as an effective way of reducing costs while maintaining quality care. OBJECTIVE: To study a practice guideline to shorten length of stay for patients hospitalized with exacerbation of COPD. METHODS: We retrospectively studied a practice guideline to identify patients who were at low risk of complications from their exacerbation of COPD and hence potentially suitable for early hospital discharge. We then prospectively studied the practice guideline using an alternate month intervention and control time series over a period of 12 months. RESULTS: The practice guideline was retrospectively studied in 250 consecutive patients hospitalized with exacerbation of COPD. Of the 250 patients, 237 patients (94.8%) were classified as low risk after 72 h of hospitalization and were potentially suitable for discharge. In the prospective study, few patients (24 of 124 or 19%) were identified for implementation of the guideline. However, in those patients who were identified, length of stay was not statistically different. The data also showed that length of stay for both intervention and control groups had shortened over this time. CONCLUSION: Certain practice guidelines may appear efficacious in studies but may actually lack effectiveness when applied in clinical settings and may even increase costs. We demonstrated the importance of prospectively evaluating clinical practice guidelines before recommending them for widespread implementation.

Guidelines for chronic obstructive pulmonary disease treatment and issues of implementation.

Chronic obstructive pulmonary disease (COPD) is a major cause of morbidity and mortality worldwide. Treatment advances over the last decade, although limited, have precipitated the development of clinical practice guidelines, with the aim of improving the quality of care received by patients through fostering evidence-based decision making and accelerating the application of new advances to everyday practice. Of the COPD guidelines that have been developed, those developed through the Global Initiative for Chronic Obstructive Lung Disease (GOLD), initially a joint activity between the U.S. National Heart, Lung, and Blood Institute and the World Health Organization, and the National Institute of Clinical Excellence (NICE) in the United Kingdom have both published their methods for evaluation of evidence. These comprehensive guidelines cover all aspects of the disease, with the aim of providing the basis for local care pathways. The guideline development process includes evaluation of the evidence, development of the guideline, and dissemination of the findings. Efforts to enhance guideline effectiveness have focused on improving the methods and approaches to implementation, which requires an appreciation of the issues that stop translation of guideline definitions of best practice into improved patient care. A variety of questions remain unanswered in the clinical management of COPD, including the definition of outcome measures that move beyond lung function, the potential application of multidimensional grading systems that assess respiratory and systemic expressions of COPD and that could possibly better categorize and predict outcome in these patients, and the impact of new clinical trial findings. Large ongoing outcome studies may also have an effect on defining best practice within future guideline recommendations.
