Research Objective: To examine racial differences in diabetes service use and outcomes in Medicare+Choice managed care plans as reported in Health Plan Employer Data and Information Set(HEDIS® ) individual level data.

Study Design: We merged HEDIS® individual level data with the Medicare Denominator file and Group Health Plan file to obtain demographic information and plan association. We compared the use of the four HEDIS® diabetes service measures with the two outcome measures. Associations of race and diabetes service use were investigated after adjusting for age, sex, plan size, profit status, plan type, individual income, and region of the country.

Principal Findings: There was a strong relationship between the number of diabetes services received and the number of favorable outcomes (Kendall's Tau-b=0.76, P<0.001). The relationship was consistent across race groups. Asians had significantly higher rate of receiving diabetes services and significantly higher rate of favorable outcomes compared to the rest of race groups. Blacks had the lowest rate of receiving diabetes services and the lowest rate of favorable outcomes. The order of number of services received and number of favorable outcomes observed was Asians, Whites, Hispanics and Blacks. The rate of diabetes services received, however, was not fully explained by age, sex, plan size, profit status, plan type, individual income, or region of the country.

Conclusions: Racial differences of diabetes outcomes were largely attributed to the differences in receiving diabetes care services. Racial differences in receiving services persisted after controlling for various factors.
