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.

Association of Medicaid expansion with quality in safety-net hospitals.
The authors compared changes in quality from 2012 to 2018 between safety net hospitals (SNHs) in states that expanded Medicaid vs those in states that did not. They found that, despite reductions in uncompensated care and improvements in operating margins, there appeared to be little evidence of quality improvement among SNHs in states that expanded Medicaid compared with those in states that did not.

Hospital characteristics associated with risk-standardized readmission rates.
This national study using Medicare data examined the independent association of 8 hospital characteristics with hospital-wide 30-day risk-standardized readmission rate (RSRR). Overall, larger, urban, academic facilities had modestly higher RSRRs than smaller, suburban, community hospitals, although there was a wide range of performance. The strong regional effect suggests that local practice patterns are an important influence.
