Abstract

This study was designed to determine whether managed care plans reduce racial disparities in use of influenza vaccination, mammography, and prostate-specific antigen screening. The study analyzed the use of three types of preventive care in a population-based sample of adults who were 65 years or older and were enrolled in a Medicare managed care (MMC) or fee-for-service (FFS) plan in Allegheny County, Pennsylvania. The study sample included 463 African Americans and 592 whites. Fewer African Americans than whites reported having had an influenza vaccination (64.4% versus 76.5%; p < 0.01) or a prostate-specific antigen test (64% versus 71.2%; p = 0.09) during the previous year. Slightly more African Americans than white women reported having had a mammogram (66.1% versus 63.8%). Logistic regression showed that, regardless of health plan type, African Americans were significantly less likely than whites to have an influenza vaccination (p < 0.05). A MMC plan did not narrow racial differences in preventive care. Reducing disparities may require interventions developed for specific racial/ethnic groups.
