Descriptive Information
Brief Title  ICMJE Enhancing the Secondary Prevention of Coronary Artery Disease
Official Title  ICMJE Enhancing the Use of Secondary Prevention Strategies in Patients With Coronary Artery Disease (The ESP-CAD Study)
Brief Summary People with coronary artery disease can reduce their chance of having a heart attack by making healthy lifestyle choices (diet, exercise, quitting smoking,etc.). There are also many medications that have been proven to reduce the risk of heart attacks and may even help people live longer. This study will look at different ways of improving the use of these beneficial medications to enhance the quality of care for people with this condition.
Detailed Description

BACKGROUND: Despite the abundant evidence base for secondary prevention, practice audits consistently demonstrate substantial "care gaps" between this evidence and clinical reality such that many patients with Coronary Artery Disease (CAD) are not offered all possible therapies for the prevention of myocardial infarction or death. For example, even after an acute myocardial infarction, almost one fifth of patients continue to smoke; over half with hypertension or hyperlipidemia have poorly controlled pressure or lipid levels; and proven therapies such as statins, ACE inhibitors, beta-blockers and antiplatelet agents are under-prescribed.

Multiple barriers are often responsible for the lack of implementation of proven efficacious therapies and traditional means of educating practitioners (journal articles, CME, conferences, etc) are usually ineffective in altering practice. Clearly novel interventions to improve the quality of prescribing are needed. Local opinion leaders are trusted by their peers to evaluate medical innovations and thus influence practice patterns within their community. Few controlled studies, however, have evaluated their effect on changing prescribing practices for common conditions such as CAD.

HYPOTHESIS: This trial will test 2 quality improvement interventions. The principle hypothesis is: does a one-page evidence summary endorsed by local opinion leaders increase the provision of secondary prevention therapies in patients with CAD compared to usual care? The secondary hypotheses are: does the same intervention but without local opinion leader endorsement improve the provision of secondary prevention strategies in patients with CAD compared to usual care? Does local opinion leader endorsement increase the effectiveness of the quality improvement intervention?
