The impacts of the 340B Program on health care quality for low-income patients.
This study’s objective was to assess the effects of hospital 340B eligibility on quality of inpatient care provided to Medicaid and uninsured patients and for all patients. HCUP State Inpatient Data, Hospital Cost Reporting Information System Data, Office of Pharmacy Affairs Information System Data, and the American Hospital Association Annual Survey were all used to extract inpatient data from general acute care hospitals from 2008 to 2014 in 15 states. Data was linked on hospital 340B eligibility and participation. The authors did not find discontinuities in inpatient care quality across the Program eligibility threshold for Medicaid and uninsured patients; specifically, on all-cause mortality, 30-day readmission rates, or other measures. Among insured and non-Medicaid patients, they found discontinuities for acute myocardial infarction and postoperative sepsis mortality.

Changes in hospital inpatient utilization following health care reform.
The purpose of this retrospective study was to estimate the effects of 2014 Medicaid expansions on inpatient outcomes using population and unemployment data from HCUP’s State Inpatient Databases. Outcomes included total admissions, referral-sensitive surgical and preventable admissions, length of stay, cost, and severity of patient illness. The authors conclude that Medicaid expansions did not change all-payer admission volumes, but expansions were associated with increased Medicaid and decreased uninsured volumes. The results of the study suggest that previously uninsured persons with a greater need for inpatient services were the most likely to gain coverage.

The role of Medicare's inpatient cost-sharing in Medicaid entry.
This study sought to isolate the effect of greater inpatient cost-sharing on Medicaid entry among Medicare beneficiaries. It concluded that Increasing Medicare cost-sharing requirements may promote Medicaid enrollment among low-income beneficiaries. Potential savings from an increased cost-sharing in the Medicare program may be offset by increased Medicaid participation.

Massachusetts inpatient Medicaid cost response to increased supplemental nutrition assistance program benefits.
This study investigated the impact of an increase in Supplemental Nutrition Assistance Program (SNAP) benefits on Medicaid costs and use in Massachusetts. It found that compared with the overall Medicaid population, cost growth for people with the selected chronic illnesses was significantly greater before the SNAP increase, as was the decline in growth afterward. Reduced hospital admissions after the SNAP increase drove the cost declines.

Children with medical complexity and Medicaid: spending and cost savings.
The authors described the expenditures for children with medical complexity insured by Medicaid across the care continuum, reported the increasingly large amount of spending on hospital care for these children, and presented a business case that estimates how cost savings might be achieved from potential reductions in hospital and emergency department use and shows how the savings could underwrite investments in outpatient and community care. They concluded by discussing the importance of these findings in the context of Medicaid's quality of care and health care reform.
