Growing Insurance Coverage Did Not Reduce Access To Care For The Continuously Insured

Recent expansions in health insurance coverage have raised concerns about health care providers' capacity to supply additional services and how that may have affected access to care for people who were already insured. When we examined data for the period 2008-14 from the Medical Expenditure Panel Survey, we found no consistent evidence that increases in the proportions of adults with insurance at the local-area level affected access to care for adults residing in the same areas who already had, and continued to have, insurance. This lack of an apparent relationship held true across eight measures of access, which included receipt of preventive care. It also held true among two adult subpopulations that may have been at greater risk for compromised access: people residing in health care professional shortage areas and Medicaid beneficiaries.
