Explaining racial and ethnic disparities in health care.

Objectives: The substantial racial and ethnic disparities in access to and use of health services are well documented. A number of studies highlight factors such as health insurance coverage and socioeconomic differences that explain some of the differences between groups, but much remains unexplained. We build on this previous research by incorporating additional factors such as attitudes about health care and neighborhood characteristics, as well as separately analyzing different Hispanic subgroups.

Pathways to access: health insurance, the health care delivery system, and racial/ethnic disparities, 1996-1999.

We examine the roles that insurance coverage, the delivery system, and external factors play in explaining persistent disparities in access among racial and ethnic groups of all ages. Using data from the 1996-1999 Medical Expenditure Panel Surveys and regression-based decomposition methods, we find that our measures of health care system capacity explain little and that while insurance clearly matters, external factors are equally important. Employment, job characteristics, and marital status are key determinants of disparities in access to insurance but are difficult for health policy to affect directly.
