Access to care improved for people who gained Medicaid or marketplace coverage in 2014.
Newly available longitudinal survey data show that people who lacked health insurance in 2013 and gained coverage through Medicaid or the Marketplaces in 2014 were far more likely to obtain a usual source of care and receive preventive care services than their counterparts who remained uninsured in 2014.

Changes in utilization and health among low-income adults after Medicaid expansion or expanded private insurance.
The researchers assessed changes in access to care, utilization, and self-reported health among low-income adults in 3 states taking alternative approaches to the ACA. They concluded that in the second year of expansion, Kentucky's Medicaid program and Arkansas's private option were associated with significant increases in outpatient utilization, preventive care, and improved health care quality; reductions in emergency department use; and improved self-reported health.

Access to mental health care increased but not for substance use, while disparities remain.
The researchers assessed whether early implementation of Affordable Care Act (ACA) Medicaid expansion and state health insurance exchanges increased access to mental health and substance use treatment among those in need and whether these changes differed by racial/ethnic group. They found that mental health treatment rates increased significantly but found no evidence of a reduction in the wide racial/ethnic disparities in mental health treatment that preceded ACA expansion from 2005 to 2013.

Reforming access: trends in Medicaid enrollment for new Medicare beneficiaries, 2008-2011.
This study evaluated whether aligning the Part D low-income subsidy and Medicaid program enrollment pathways in 2010 increased Medicaid participation among new Medicare beneficiaries. It found that the percentage of beneficiaries enrolling in limited Medicaid at the start of Medicare coverage increased in 2010 by 0.3 percentage points for individuals aging into Medicare and by 1.3 percentage points for those qualifying due to disability.

Understanding patient, provider, and system factors related to Medicaid readmissions.
This study was undertaken to understand the complexity of Medicaid readmission issues at the patient, provider, and system levels. It found that significant risk factors for Medicaid readmissions included financial stress, high prevalence of mental health and substance abuse disorders, medication nonadherence, and housing instability. Lacking awareness on Medicaid patients' high risk, a sufficient business case, and proven strategies for reducing readmissions were primary barriers for providers.

Receipt of preventive services after Oregon's randomized Medicaid experiment.
This study examined the three-year impact of Oregon's 2008 randomized Medicaid expansion (the "Oregon Experiment") on receipt of 12 preventive care services in community health centers using electronic health record data. They found that Medicaid coverage significantly increased the odds of receipt of most preventive services. They concluded that rates of preventive services receipt will likely increase as community health center patients gain insurance through Affordable Care Act expansions. They recommended continued effort to increase health insurance coverage in an effort to decrease health disparities in vulnerable populations.

The effect of Medicaid adult vision coverage on the likelihood of appropriate correction of distance vision: evidence from the National Health and Nutrition Examination Survey.
This paper examined whether providing adult vision benefits is associated with an increase in the percentage of low-income individuals with appropriately corrected distance vision as measured during an eye exam. Findings imply that Medicaid adult vision coverage is associated with a significant increase in the percentage of Medicaid beneficiaries with appropriately corrected distance vision.

Both the 'private option' and traditional Medicaid expansions improved access to care for low-income adults.
This study found that other than coverage type and trouble paying medical bills (which decreased more in Kentucky than in Arkansas), there were no significant differences between Kentucky's traditional Medicaid expansion and Arkansas's private option, which suggests that both approaches improved access among low-income adults.

Measuring Medicaid physician participation rates and implications for policy.
The authors’ objective was to describe several alternative measures of provider participation in Medicaid using recently publicly available data, to compare state rankings across these different metrics, and to discuss potential advantages and disadvantages of each measure for research and policy purposes. Overall, they found that Medicaid participation as measured by raw percentages of physicians taking new Medicaid patients is only weakly correlated with population-based measures that account for both participation rates and the numbers of physicians per capita or physicians per Medicaid beneficiary.
