  • PPC-RS = Physician Practice Connections Research Survey.

  • a Possible range of scores: 0 to 100.

  • Notes: Numbers of clinics for each score/measure ranged from 98 to 102, as some had missing data. Optimal diabetes rate = percentage of patients with diabetes meeting all thresholds for control of hemoglobin A1c, blood pressure, and lipids as well as aspirin use and tobacco abstinence. Optimal vascular rate = percentage of patients with heart disease meeting all thresholds for control of blood pressure and lipids as well as aspirin use and tobacco abstinence.
