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.

Impact of Medicaid expansion on cardiac surgery volume and outcomes.
The objective of this study was to evaluate the effect of Medicaid expansion on cardiac surgery volume and outcomes comparing one state that expanded to one that did not. It concluded that Medicaid expansion was associated with fewer uninsured cardiac surgery patients and improved predicted risk scores and morbidity rates. In addition to improving health care financing, Medicaid expansion may positively affect patient care and outcomes.

Medicaid expansion produces long-term impact on insurance coverage rates in community health centers.
This study assesses changes in insurance status of patients visiting community health centers (CHCs) comparing states that expanded Medicaid to those that did not. Rates of uninsured visits decreased pre- to post- Affordable Care Act with greater drops in expansion (-57 percent) versus nonexpansion (-20 percent) states. Medicaid-insured visits increased 60 percent in expansion states while remaining unchanged in nonexpansion states.

Psychological distress and enrollment in Medicaid.
Adults with poor mental health may want and need insurance to obtain care, but symptoms may impede enrollment into public health insurance. The enrollment response to Medicaid expansions prior to the Affordable Care Act was stronger for adults symptomatic of psychological distress compared with adults without distress and compared to adults with chronic physical health problems.

Medicaid's impact on chronic disease biomarkers: a cohort study of community health center patients.
This study assessed changes in biomarkers of chronic disease among community health center (CHC) patients who gained Medicaid coverage with the Oregon Medicaid expansion (2008-2011). It found that patients with uncontrolled chronic conditions experienced objective health improvements over time. In two of three chronic disease cohorts, those who gained Medicaid coverage were more likely to achieve a controlled measurement than those who remained uninsured.

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.

Premium subsidies, the mandate, and Medicaid expansion: coverage effects of the Affordable Care Act.
Using premium subsidies for private coverage, an individual mandate, and Medicaid expansion, the Affordable Care Act (ACA) has increased insurance coverage. Win this study, the investigators provide the first comprehensive assessment of these provisions' effects, using the 2012-2015 American Community Survey and a triple-difference estimation strategy that exploits variation by income, geography, and time.

Adults are more likely to become eligible for Medicaid during future recessions if their state expanded Medicaid.
The researchers simulated eligibility for Medicaid for the period 2005-14 in two scenarios: assuming that each state's eligibility rules in 2009, the year before passage of the Affordable Care Act (ACA), were in place during the entire study period; and assuming that the ACA's expanded eligibility rules were in place during the entire period for all states. Their simulations showed that the ACA expansion increased Medicaid's responsiveness to changes in unemployment.

Most newly insured people in 2014 were long-term uninsured.
This study found that in 2014-after the implementation of most of the Affordable Care Act provisions, including Medicaid expansions in some states and subsidies to purchase Marketplace coverage in all states-adults who had been uninsured for more than three years represented a larger share of the newly insured, compared to adults who had been insured for shorter periods of time.

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.

What factors influence states' capacity to report children's health care quality measures? A multiple-case study.
The objective of this study was to describe factors that influence the ability of state Medicaid agencies to report the Centers for Medicare & Medicaid Services' (CMS) core set of children's health care quality measures . Reporting capacity was influenced by a state's Medicaid data availability, ability to link to other state data systems, past experience with quality measurement, staff time and technical expertise, and demand for the measures.
