Geographic access to federally qualified health centers before and after the Affordable Care Act.
Funding for Federally Qualified Health Centers (FQHCs) increased with the advent of the Affordable Care Act (ACA). The purpose of this study was to define FQHC service areas based on patient use and examine the characteristics of areas that gained FQHC access post-ACA. The researchers first defined FQHC service areas using total patient counts by ZIP code from the Uniform Data System (UDS) and then compared that approach with other methods. The authors then compared the characteristics of ZIP codes from Medically Underserved Areas/ Populations (MUA/Ps) that gained access to FQHCs between 2011-2015, with MUA/P ZIP codes that did not gain access to FQHCs during that same time period. The study found that FQHC service areas based on the UDS data included a larger percentage of FQHC patients and a higher use of FQHCs among low-income residents, on average, than Primary Care Service Areas or counties. The researchers also discovered that MUA/Ps that gained access to an FQHC between 2011 and 2015 included more poor, publicly insured, uninsured, and foreign born residents than underserved areas that did not gain access. The study concluded that measures of actual patient use are a useful method of assessing FQHC service areas and access.

Immigrants and the Affordable Care Act: changes in coverage and access to care by documentation status.
This study used data from the California Health Interview Survey (2003-2016) to compare changes in health coverage and access to care among immigrants in California before and after the Affordable Care Act (ACA). The authors found that the ACA has led to major gains in coverage for lawful permanent residents in California, but unauthorized immigrants experienced only modest increases in coverage. This result widened the disparity in uninsured rates for unauthorized immigrants relative to citizens considerably since 2014.

Federal investments to eliminate racial/ethnic health-care disparities.
The authors presented a model that describes the relationships among social disadvantage, health-care disparities, and health disparities. They proposed that increasing the diversity of the public health and health-care workforces is an efficient strategy for reducing disparities because it impacts both access to care and patient-provider communication.
