Abstract
OBJECTIVES: We examined disparities among US adults with disabilities and the degree to which health insurance attenuates disparities by race, ethnicity, and socioeconomic status (SES). METHODS: We pooled data from the 2001-2007 Medical Expenditure Panel Survey on individuals with disabilities aged 18 to 64 years. We modeled measures of access and use as functions of predisposing, enabling, need, and contextual factors. We then included health insurance and examined the extent to which it reduced observed differences by race, ethnicity, and SES. RESULTS: We found evidence of disparities in access and use among adults with disabilities. Adjusting for health insurance reduced these disparities most consistently for emergency department use. Uninsured individuals experienced substantially poorer access across most measures, including reporting a usual source of care and experiencing delays in or being unable to obtain care. CONCLUSIONS: Although health insurance is an important enabling resource among adults with disabilities, its effect on reducing differences by race, ethnicity, and SES on health care access and use was limited. Research exploring the effects of factors such as patient-provider interactions is warranted.
