Data and Measures
We obtained 1999 claims and enrollment data from 9 Medicare and 10 commercial plans representing approximately 200,000 Medicare and 2.1 million commercial enrollees in 4 geographic regions. All 19 plans were affiliated with the same national health insurer.
We used the claims and enrollment data to calculate performance rates for 7 quality measures focused on processes of care for patients with CVD and diabetes (Table 1). This set of measures included 6 NCQA HEDIS measures (β-blocker use after
Results
As shown in Table 2, the number of enrollees meeting eligibility criteria varied by measure and insurance type, ranging from 34,981 commercial (45% of whom were women) and 15,252 Medicare (53% of whom were women) enrollees for HgbA1c testing in diabetics to 727 commercial (21% women) and 275 Medicare (40% women) enrollees for β-blocker treatment after MI.
Before adjustment for covariates, gender differences in care were detected for 6 of 11 measures among Medicare enrollees, and for 7 of 11
Discussion
We found gender differences for a variety of quality of care measures for CVD and diabetes among both commercial and Medicare health plan enrollees in a geographically diverse set of health plans associated with 1 national insurer. Gender differences were observed for screening, treatment, and intermediate outcomes. In general, the quality of care was better on process measures than on intermediate outcome measures and the opportunity exists to improve quality of care for both men and women.

She is currently completing a book with Patricia Rieker titled Gender and Health: The Effects of Constrained Choice and Social Policies in which they examine how differences in the social organization of men’s and women’s lives contribute to differences in their health.
