Abstract
This study examined whether the Medicare Part D program was associated with racial/ethnic disparities in prescription drug access among elderly individuals who reported adequate access to physicians. Using a population-based survey of New Jersey residents, a difference-in-differences model estimated elderly blacks (OR = 3.20; p = .05) and Hispanics (OR = 4.29; p = .05) had higher odds than whites of reporting prescription access problems in the post, but not the pre-Part D period. The presence of prescription insurance did not lead to a significant decrease in access problems. Part D beneficiaries are required to make complicated decisions on cost-sharing and medication choices that require active involvement by physicians and pharmacists. Lack of guidance may critically impact minorities and economically vulnerable patients and cannot be addressed by extending coverage alone.
