ObjectiveTo examine recent changes in racial and ethnic disparities in access to physician services in the United States, and investigate the economic factors driving the changes observed.MethodsUsing nationally representative data on adults aged 25-64 from the 2000 and 2007 Medical Expenditure Panel Survey, we examine changes in two measures of access: whether the individual reported having a usual source of care, and whether he/she had any doctor visits during the past year. In each year, we calculate disparities in access between African Americans and Whites, and between Hispanics and Whites, applying the Institute of Medicine's definition of a disparity. Nonlinear regression decomposition techniques are then used to quantify how changes in personal characteristics, comparing 2000 and 2007, helped shape the changes observed.ResultsLarge disparities in access to physician care were evident for both minority groups in 2000 and 2007. Disparities in no doctor visits during the past year diminished for African Americans, but disparities in both measures worsened sharply for Hispanics.ConclusionsDisparities in access to physician care are improving for African Americans in one dimension, but eroding for Hispanics in multiple dimensions. The most important contributing factors to the growing disparities between Hispanics and Whites are health insurance, education, and income differences.
