Adult diabetic patients age 18 years and older receiving primary care in the Brigham Internal Medicine Associates (BIMA) practice will be randomized to intervention and control groups, based on the practice subset (Suite) within BIMA in which they receive their ongoing care. Patients who receive care from providers in Suites A, B, E, and F will be assigned to the intervention group, while patients who receive care from providers in Suites C, D, G, and H will be assigned to the control group. Patients will not be contacted regarding the study; providers who practice in the intervention Suites will receive specific written recommendations regarding optimal diabetes care parameters from our study pharmacist prior to each patient's visit. Providers who practice in the control Suites will not be contacted. Pre- and post-intervention compliance with multiple diabetes quality-of-care measures (eg, Hemoglobin A1c measurement, LDL cholesterol measurement, pneumococcal vaccination, etc.) will be assessed in the intervention and control groups.
