Association between Medicaid expansion, dental coverage policies for adults, and children's receipt of preventive dental services.
Researchers examined whether low-income children's use of preventive dental services is linked to variation in state Medicaid policies that affect parents' access to dental care in Medicaid. Using MEPS data along with Area Health Resources File and Medicaid adult dental coverage policies, they found no change in children's receipt of preventive dental care associated with Medicaid expansions in states that covered vs did not cover preventive dental services for adults. They concluded that factors other than parental access to dental benefits through Medicaid may be more salient determinants of preventive dental care use among low-income children.

Medicaid expansion and marketplace eligibility both increased coverage, with trade-offs in access, affordability.
The researchers found that as of 2015, adults with incomes of 100-138 percent of the federal poverty level had experienced large declines in uninsurance rates in both expansion and nonexpansion states. Adults in expansion and nonexpansion states also experienced similar increases in having a usual source of care and primary care visits, and similar reductions in delayed receipt of medical care due to cost.

Medicaid expansion for adults had measurable 'welcome mat' effects on their children.
This study used data from the 2013-15 American Community Survey to provide the first national-level (analytical) estimates of welcome-mat effects on children's coverage post Affordable Care Act (ACA). It estimated that 710,000 low-income children gained coverage through these effects. The study was also the first to show a link between parents' eligibility for Medicaid and welcome-mat effects for their children under the ACA.

In low-income Latino patients, post-affordable care act insurance disparities may be reduced even more than broader national estimates: evidence from Oregon.
This study compared the insurance status of low-income patients served in 23 community health centers (CHCs) in Oregon, by race/ethnicity and language, over a period of 6 years straddling the implementation of ACA-related Medicaid expansion in 2014. It found that among previously uninsured low-income patients returning to Oregon CHCs, insurance disparities were eliminated after Medicaid expansion, especially in Spanish-speaking Latinos.

Three-year impacts of the Affordable Care Act: improved medical care and health among low-income adults.
Using survey data collected from low-income adults through the end of 2016 in three states: Kentucky, which expanded Medicaid; Arkansas, which expanded private insurance to low-income adults using the federal Marketplace; and Texas, which did not expand coverage, researchers found that by the end of 2016 the uninsurance rate in the two expansion states had dropped by more than 20 percentage points relative to the nonexpansion state.

Medicaid expansion coverage effects grew in 2015 with continued improvements in coverage quality.
The researchers used detailed federal survey data through 2015 to analyze recent changes in coverage for low-income adults after the expansion associated with the Affordable Care Act's (ACA's) Medicaid expansion in 2014. They found that the uninsurance rate fell in both expansion and nonexpansion states but that it fell significantly more in expansion states.

At federally funded health centers, Medicaid expansion was associated with improved quality of care.
In 2014 many uninsured, low-income nonelderly adults gained access to health insurance in states that expanded Medicaid eligibility under the Affordable Care Act. The researchers used a difference-in-differences approach to compare changes among 1,057 such centers in expansion versus nonexpansion States. Medicaid expansion was associated with improved quality for asthma treatment, Pap testing, body mass index assessment, and hypertension control.
