RESUMEN

In 1999, the American College of Physicians (ACP), then the American College of Physicians-American Society of Internal Medicine, and the American College of Cardiology/American Heart Association (ACC/AHA) developed joint guidelines on the management of patients with chronic stable angina. The ACC/AHA then published an updated guideline in 2002, which ACP recognized as a scientifically valid review of the evidence and background paper. This ACP guideline summarizes the recommendations of the 2002 ACC/AHA updated guideline and underscores the recommendations most likely to be important to physicians seeing patients in the primary care setting. This guideline is the second of 2 that provide guidance on the management of patients with chronic stable angina. This document covers treatment and follow-up of symptomatic patients who have not had an acute myocardial infarction or revascularization procedure in the previous 6 months. Sections addressing asymptomatic patients are also included. Asymptomatic refers to patients with known or suspected coronary disease based on a history or electrocardiographic evidence of previous myocardial infarction, coronary angiography, or abnormal results on noninvasive tests. A previous guideline covered diagnosis and risk stratification for symptomatic patients who have not had an acute myocardial infarction or revascularization procedure in the previous 6 months and asymptomatic patients with known or suspected coronary disease based on a history or electrocardiographic evidence of previous myocardial infarction, coronary angiography, or abnormal results on noninvasive tests.

This guideline is the first of 2 that will provide guidance on the management of patients with chronic stable angina. This document will cover diagnosis and risk stratification for symptomatic patients who have not had an acute myocardial infarction or revascularization procedure in the previous 6 months. Sections addressing asymptomatic patients are also included. Asymptomatic refers to patients with known or suspected coronary disease based on history or on electrocardiographic evidence of previous myocardial infarction, coronary angiography, or abnormal results on noninvasive tests. A future guideline will cover pharmacologic therapy and follow-up.

RESUMEN

OBJECTIVE: To evaluate the effectiveness of a patient guideline for educating the public in the recognition and treatment of depression. METHOD: Lay subjects were interviewed regarding their knowledge and beliefs about depression through the use of a semi-structured questionnaire. They were asked to "think aloud" while evaluating two clinical scenarios about depression, both with and without the use of a patient guideline. All interviews were audio taped, transcribed, and analyzed for subjects' thought processes and accuracy of responses in the presence and absence of the guideline. RESULTS: Subjects with no prior history of depression identified fewer symptoms of depression listed in the patient guideline than did subjects with a history of depression. In the absence of the guideline, only 50% and 38% of subjects provided accurate diagnosis of depression for the simple and complex problems respectively. In the presence of the guideline, 92% and 83% of subjects provided an accurate diagnosis of depression for the simple and complex problems respectively. CONCLUSIONS: Lay people have a limited knowledge of depression and its treatment, and are less able to recognize symptoms of depression without the help of patient guideline. The guideline primes lay people to better recognize these symptoms and their relationship to diagnosis. This level of understanding about depression by lay people will facilitate improved communication between physicians and their patients.

RESUMEN

In an effort to provide internists and other primary care physicians with effective management strategies for diabetes care, the Clinical Efficacy Assessment Subcommittee (CEAS) of the American College of Physicians (ACP) decided to develop guidelines on the management of dyslipidemia, particularly hypercholesterolemia, in people with type 2 diabetes mellitus. The CEAS commissioned a systematic review of the currently available evidence on the management of lipids in type 2 diabetes mellitus. The evidence review is presented in a background paper in this issue. On the basis of this systematic review, the CEAS developed recommendations that the ACP Board of Regents then approved as policy. The target audience for this guideline is all clinicians who care for patients with type 2 diabetes. The target patient population is all persons with type 2 diabetes, including those who already have some form of microvascular complication and, of particular importance, premenopausal women. The recommendations are as follows. RECOMMENDATION 1: Lipid-lowering therapy should be used for secondary prevention of cardiovascular mortality and morbidity for all patients (both men and women) with known coronary artery disease and type 2 diabetes. RECOMMENDATION 2: Statins should be used for primary prevention against macrovascular complications in patients (both men and women) with type 2 diabetes and other cardiovascular risk factors. RECOMMENDATION 3: Once lipid-lowering therapy is initiated, patients with type 2 diabetes mellitus should be taking at least moderate doses of a statin. RECOMMENDATION 4: For those patients with type 2 diabetes who are taking statins, routine monitoring of liver function tests or muscle enzymes is not recommended except in specific circumstances.

RESUMEN

The Joint Panel of the American Academy of Family Physicians and the American College of Physicians, in collaboration with the Johns Hopkins Evidence-based Practice Center, systematically reviewed the available evidence on the management of newly detected atrial fibrillation and developed recommendations for adult patients with first-detected atrial fibrillation. The recommendations do not apply to patients with postoperative or post-myocardial infarction atrial fibrillation, patients with class IV heart failure, patients already taking antiarrhythmic drugs, or patients with valvular disease. The target physician audience is internists and family physicians dedicated to primary care. The recommendations are as follows: RECOMMENDATION 1: Rate control with chronic anticoagulation is the recommended strategy for the majority of patients with atrial fibrillation. Rhythm control has not been shown to be superior to rate control (with chronic anticoagulation) in reducing morbidity and mortality and may be inferior in some patient subgroups to rate control. Rhythm control is appropriate when based on other special considerations, such as patient symptoms, exercise tolerance, and patient preference. Grade: 2A. RECOMMENDATION 2: Patients with atrial fibrillation should receive chronic anticoagulation with adjusted-dose warfarin, unless they are at low risk of stroke or have a specific contraindication to the use of warfarin (thrombocytopenia, recent trauma or surgery, alcoholism). Grade: 1A. RECOMMENDATION 3: For patients with atrial fibrillation, the following drugs are recommended for their demonstrated efficacy in rate control during exercise and while at rest: atenolol, metoprolol, diltiazem, and verapamil (drugs listed alphabetically by class). Digoxin is only effective for rate control at rest and therefore should only be used as a second-line agent for rate control in atrial fibrillation. Grade: 1B. RECOMMENDATION 4: For those patients who elect to undergo acute cardioversion to achieve sinus rhythm in atrial fibrillation, both direct-current cardioversion (Grade: 1C+) and pharmacological conversion (Grade: 2A) are appropriate options. RECOMMENDATION 5: Both transesophageal echocardiography with short-term prior anticoagulation followed by early acute cardioversion (in the absence of intracardiac thrombus) with postcardioversion anticoagulation versus delayed cardioversion with pre- and postanticoagulation are appropriate management strategies for those patients who elect to undergo cardioversion. Grade: 2A. RECOMMENDATION 6: Most patients converted to sinus rhythm from atrial fibrillation should not be placed on rhythm maintenance therapy since the risks outweigh the benefits. In a selected group of patients whose quality of life is compromised by atrial fibrillation, the recommended pharmacologic agents for rhythm maintenance are amiodarone, disopyramide, propafenone, and sotalol (drugs listed in alphabetical order). The choice of agent predominantly depends on specific risk of side effects based on patient characteristics. Grade: 2A.

RESUMEN

Clinical guidelines aim to eliminate clinician errors, reduce practice variation, and promote best medical practices. Computer-interpretable guidelines (CIGs) can deliver patient-specific advice during clinical encounters, which makes them more likely to affect clinician behavior than narrative guidelines. To reduce the number of errors that are introduced while developing narrative guidelines and CIGs, we studied the process used by the ACP-ASIM to develop clinical algorithms from narrative guidelines. We analyzed how changes progressed between subsequent versions of an algorithm and between a narrative guideline and its derived clinical algorithm. We recommend procedures that could limit the number of errors produced when generating clinical algorithms. In addition, we developed a tool for authoring CIGs in GLIF3 format and validating their syntax, data type matches, cardinality constraints, and structural integrity constraints. We used this tool to author guidelines and to check them for errors.
