Brief summary

Our aim is to determine if a patient-directed intervention is more effective than computerized clinician reminders alone for improving aspirin use in adults with diabetes.

Detailed description

Many patients with diabetes do not use aspirin to prevent cardiovascular events. Quality improvement initiatives involving both patients and physicians may be more effective than physician-directed approaches alone. In a large urban primary care internal medicine practice, this study seeks to test if a patient-directed intervention is more effective than computerized clinician reminders alone for improving the appropriate use of aspirin in adults with diabetes. The study design is a cluster-randomized trial by physician. The frequency of self-reported regular aspirin use will be compared between patients cared for by physicians in the computerized reminder alone group and the computerized reminder plus physician-supervised, nurse practitioner intervention group.
