Association of Medicaid expansion in Arkansas with postpartum coverage, outpatient care, and racial disparities.
This study’s objective was to measure the association of Medicaid expansion in Arkansas with postpartum coverage, outpatient care, and racial disparities. A total of 60,990 childbirths were reviewed from January 1, 2014 on with a total of 72.3% paid for by Medicaid and 27.7% paid for by a commercial payer. The mean age of the birthing person was 27; with 67% White, 22% Black, and 7% Hispanic. Medicaid expansion in Arkansas was associated with a 27.8 percentage point increase in continuous insurance coverage and an increase in outpatient visits of 0.9 during the first 6 months postpartum, representing relative increases of 54.9% and 75.0%, respectively. Racial disparities in postpartum coverage decreased from 6.3 percentage points before expansion to -2.0 after. However, disparities in outpatient care after expansion persisted between Black and White individuals.

State policies and enrollees' experiences in Medicaid: evidence from a new national survey.
This study examined patient satisfaction among Medicaid enrollees nationally from 2014-2015. Significant disparities were found among racial/ethnic groups. Managed care enrollees had higher satisfaction ratings than those with fee-for-service. If the patient had a personal doctor that increased satisfaction for an average 4.6 percent.

Household immigration status had differential impact on Medicaid enrollment in expansion and nonexpansion states.
This study identified households that likely included undocumented immigrants and then examined whether gains in health care coverage due to the expansion of Medicaid eligibility under the Affordable Care Act (ACA) were dampened for eligible people living in households with mixed immigration status. It found that coverage gains were significantly lower for people in mixed-status households relative to those in non-mixed-status households in nonexpansion states.

Social effects of health care reform: Medicaid expansion under the Affordable Care Act and changes in volunteering.
This article examined whether public health policy interventions result in pro-social behaviors. Specifically, it examined the association between Medicaid and volunteer work. Volunteerism is implicated in individuals' health and well-being yet it is highly correlated with a person's existing socioeconomic resources. The investigators found that increased volunteer work associated with Medicaid was greater among minority groups and narrowed existing ethnic differences in volunteerism in states that expanded Medicaid eligibility.

California's early coverage expansion under the Affordable Care Act: a county-level analysis.
The researchers assessed the coverage effects of California's 2011 Low-Income Health Program (LIHP), enacted as an "early expansion" under the Affordable Care Act (ACA), and to demonstrate the feasibility of using Census data to measure county-level coverage changes. They concluded that California's 2011 expansion produced significant increases in public coverage for low-income individuals, particularly Latinos.
