 The primary care clinic at each of the six VISN 13 facilities will serve as intervention sites. Within those sites we will randomize providers to one of three reminder systems. Control sites will consist of twelve other facilities matched to the intervention sites on the basis of facility characteristics. We will use a modified pre-post nested cohort design that allows us to evaluate the effect of the intervention controlling for secular trends. Target patients will be identified based on the following: 1. an IHD diagnosis within the past 5 years; 2. regular follow-up in a primary care clinic; 3. most recent LDL-cholesterol 130 mgdl and HDL-cholesterol 40 mgdl; 4. No lipid therapy within prior 6 months. The intervention will consist of: a. an on-site interactive educational workshop for providers; b. reminders either patient-directed mailed reminders, computer-chart reminders at the time of visit, or automatic consults; c. opinion leader recruitment and activation. The primary outcome is proportion of target patients receiving guideline-concordant therapy. For objective 1, the outcome will be compared between intervention and control sites. For objective 2, the outcome will be compared between the three groups randomized to the different reminder systems. In addition, providers will be surveyed with a written questionnaire to determine their reaction to the educational workshop and the different reminder systems.
