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.

Association of insurance gains and losses with access to prescription drugs.
The researchers used longitudinal data to assess the effects of insurance gains and losses on prescription drug access. Their findings that unmet need for prescription drugs declined among initially uninsured adults who gained coverage and doubled among initially insured adults who lost coverage provide longitudinal evidence that having and maintaining health insurance is a key protection against unmet need for prescription drugs in a nationally representative sample.

Association of state access standards with accessibility to specialists for Medicaid managed care enrollees.
The researchers compared ratings of access to specialists for adult Medicaid and commercial enrollees before and after the implementation of specialty access standards. Overall, there was no significant improvement in timely access to specialty services for Medicaid managed care enrollees in the period following implementation of standard(s) nor was there any impact of access standards on insurance-based disparities in access.

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.

Growing insurance coverage did not reduce access to care for the continuously insured.
The researchers examined data for the period 2008-14 from the Medical Expenditure Panel Survey and found no consistent evidence that increases in the proportions of adults with insurance at the local-area level affected access to care for adults residing in the same areas who already had, and continued to have, insurance.

The Mental Health Parity and Addiction Equity Act (MHPAEA) evaluation study: impact on quantitative treatment limits.
This study assessed Mental Health Parity and Addiction Equity Act’s (MHPAEA) effect on the prevalence of behavioral health quantitative treatment limits (QTLs). It concluded that, before MHPAEA, QTLs were common. Postimplementation, virtually all plans dropped such limits, suggesting that MHPAEA was effective at eliminating QTLs.

Medicaid's lasting impressions: population health and insurance at birth.
This article examines lasting mortality improvements associated with availability of Medicaid at time and place of birth. Being born after Medicaid was associated with between 2.03 and 3.64 fewer deaths per 100,000 person-years in childhood and between 1.35 and 3.86 fewer deaths per 100,000 person-years in the thirties. The association between Medicaid at birth and mortality was the strongest in the oldest age group (36-40) in this study.

Protocol for the analysis of a natural experiment on the impact of the Affordable Care Act on diabetes care in community health centers.
It is hypothesized that Affordable Care Act (ACA) Medicaid expansions could substantially improve access to health insurance and healthcare services for patients at risk for diabetes mellitus (DM), with pre-DM, or already diagnosed with DM. Data collection will include information on changes in health insurance, service receipt, and health outcomes, spanning 9 years (pre- and post-expansion), comparing states that expanded Medicaid, and those that did not.
