Effects of the Children's Health Insurance Reauthorization Act on immigrant children's healthcare access.
The purpose of this study was to estimate the effects of the Children's Health Insurance Reauthorization Act (CHIPRA) on insurance coverage, access, utilization, and health outcomes among immigrant children. The researchers utilized the restricted use 2000-2016 National Health Interview Survey (NHIS)with a sample which included immigrant children between the ages of 0 and 18 born outside the United States, with family income below 300% of the Federal Poverty Level (FPL). The study found that CHIPRA was related with a decrease in uninsured rates and an increase in public insurance enrollment for immigrant children. The effects of CHIPRA became small and statistically not significant 3 years after adoption. The researchers found no significant changes in health care access and utilization, and health outcomes, overall and across subgroups due to CHIPRA. The researchers concluded that the eligibility expansion of CHIPRA was related with increases in public insurance coverage for low-income children. However, no effect of CHIPRA on access to care and health was found.

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.

Association of socioeconomic characteristics with where children receive emergency care.
This study’s objective was to characterize national associations of neighborhood income and insurance type for children with the characteristics of emergency departments (EDs) from which they receive care. The authors conducted a cross-sectional study of ED visits by children from 2014 to 2017 using the Nationwide Emergency Department Sample. Emergency department characteristics were characterized by pediatric volume category. There was a total of 107.6 million ED visits from 2014 to 2017. Children outside of the wealthiest neighborhood income quartile had lower proportions of visits to high-volume pediatric EDs and greater proportions of visits to low-volume pediatric EDs than children in the wealthiest quartile. Publicly insured children were modestly more likely to visit higher-volume pediatric EDs than privately insurance and uninsured children. This association appears to be principally driven by urban-rural differences in access to pediatric emergency care.

FQHC designation and safety net patient revenue associated with primary care practice capabilities for access and quality.
Researchers assessed capabilities around access to and quality of care among primary care practices serving a high share of Medicaid and uninsured patients compared to practices serving a low share of these patients. Data from the National Survey of Healthcare Organizations and Systems was analyzed. They found that federally qualified health centers were more likely than other types of primary care practices (both safety net practices and other practices) to possess capabilities related to access and quality. However, safety net practices were less likely than non-safety net practices to possess health information technology capabilities.

Insurance coverage for non-standard workers: experiences of temporary workers, freelancers, and part-time workers in the USA, 2010-2017.
This AHRQ-authored paper estimates insurance disparities across non-standard employment categories and determines how coverage disparities shifted following health reform in 2014. Data on working-age adults was analyzed from the 2010-2012 and 2015-2017 MEPS. Uninsurance decreased after health reform for all groups of nonstandard workers with a 10-14% point decline. Uninsurance remained high for all freelance workers at 30.8%, full-time temporary workers (25.1%) and part-time workers (17.9%) compared to full-time workers (11.9%). Lower uninsurance in a Medicaid expansion state was found for all categories of workers.

Impacts of the Affordable Care Act on receipt of women's preventive services in Community Health Centers in Medicaid expansion and nonexpansion states.
Researchers assessed whether ACA implementation and Medicaid expansion were followed by greater receipt of recommended preventive services among women and girls in a large network of community health centers. Data was collected from electronic health records in 14 states. The researchers found that among female patients at community health centers, receipt of recommended preventive care improved after ACA implementation in both Medicaid expansion and non-expansion states, although the overall rates remained low. They recommended continued support to overcome barriers to preventive care in this population.
