Quality of care of Medicare patients with diabetes in a metropolitan fee-for-service primary care integrated delivery system

Abstract

Diabetes care in the United States is suboptimal. Although closed-panel health maintenance organizations (HMOs) and the Department of Veterans Affairs (VA) report performance superior to national norms, fee-for-service performance is uncertain. To address this issue, 3 outcome and 5 process indicators were measured for 2010 Medicare diabetes patients across 22 sites in a large, fee-for-service primary care group practice. American Diabetes Association standards for glycemic control, low-density lipoprotein cholesterol, and blood pressure were met by 53%, 46%, and 19% of patients, respectively. Diabetes Quality Improvement Project/Alliance poor control markers for the same measures were exceeded by 9%, 20%, and 54% of patients. Chart abstraction demonstrated annual eye examination, foot examination, and nephropathy screening rates of 16%, 49%, and 38%, while Medicare claims showed an annual eye examination rate of 63%. Observed processes and outcomes in this fee-for-service setting were superior to reported national performance and similar to the best performance in staff-model HMOs and the VA.
