There and Back Again: How the Repeal of ACA Can Impact Community Health Centers and the Populations They Serve.

We examined the impact of Medicaid expansion on rates of the remaining uninsured at the federally qualified health center level by race/ethnicity, limited English proficiency, and poverty status of their patients. Results indicated a systematic disadvantage in nonexpansion states for federally qualified health centers with high concentrations of these populations and an advantage in expansion states for federally qualified health centers with fewer limited English proficiency patients. Our findings highlight the importance of maintaining the Affordable Care Act in reducing disparities in coverage and the importance of federal funding to continue services for the remaining uninsured and vulnerable populations in both expansion and nonexpansion states.
