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.

Condition or disease Intervention/treatment Phase
Diabetes Mellitus Behavioral: Electronic prompt plus patient-directed intervention Behavioral: Electronic prompt to clinician to prescribe aspirin Not Applicable

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.
