Early impact of the Affordable Care Act coverage expansion on safety-net hospital inpatient payer mix and market shares.
The purpose of the study was to examine the impact of the Affordable Care Act's coverage expansion on safety-net hospitals (SNHs). The investigators concluded that postexpansion, non-SNHs experienced a greater percentage increase in Medicaid stays than did SNHs, which may reflect patients choosing non-SNHs over SNHs or a crowd-out of private insurance.

Estimating the causal effects of chronic disease combinations on 30-day hospital readmissions based on observational Medicaid data.
The purpose of this study was to demonstrate how observational causal inference methods can generate insights into the impact of chronic disease combinations on patients' 30-day hospital readmissions. The investigators concluded that multi-hypothesis causal analysis, a new methodological tool, generates meaningful insights from health care claims data, guiding the design of care and intervention programs.

Shifts in Medicaid and uninsured payer mix at safety-net and non-safety-net hospitals during the Great Recession.
The authors examined payer mix at safety-net hospitals (SNHs) and non-SNHs during a period covering the Great Recession using data from 38 states. The number of privately insured stays decreased at both SNHs and non-SNHs. Non-SNHs increasingly served Medicaid-enrolled and uninsured patients; in SNHs, the number of Medicaid stays decreased and uninsured stays remained stable.

Understanding the relationship between Medicaid expansions and hospital closures.
The investigators hypothesized that Medicaid expansion of eligibility for childless adults prevents hospital closures because increased Medicaid coverage for previously uninsured people reduces uncompensated care expenditures and strengthens hospitals' financial position. They tested this hypothesis using data for the period 2008-16 on hospital closures and financial performance and discuss their findings in this paper.
