Racial and ethnic disparities in preventable hospitalizations and ED visits five years after ACA Medicaid expansions,.
This AHRQ-authored paper examined whether the 2014 Affordable Care Act (ACA) Medicaid expansions mitigated existing racial or ethnic disparities in preventable hospitalizations and emergency department (ED) visits. The authors used inpatient data from twenty-nine states and ED data from twenty-six states for the period 2011 to 2018. They found that Medicaid expansions decreased disparities in preventable hospitalizations and ED visits between non-Hispanic Black and White nonelderly adults by 10 percent or more. There were no significant effects on disparities between Hispanic and non-Hispanic White nonelderly adults. Their findings highlight sustained improvements in community-level care for non-Hispanic Black populations, but also suggest access barriers experienced by Hispanic adults that need to be addressed beyond Medicaid eligibility expansion.

Racial and ethnic disparities in utilization rate, hospital volume, and perioperative outcomes after total knee arthroplasty.
The researchers sought to study racial disparities in the utilization of total knee arthroplasty (TKA), the use of high-volume hospitals, and TKA outcomes, including mortality and complications, using all-payer databases. They found that minorities had lower rates of TKA utilization but higher rates of adverse health outcomes associated with the procedure, even after adjusting for patient-related and health-care system-related characteristics.

Has access to care changed in minority communities? A study of preventable hospitalizations over time in selected States.
Basu assessed the changes in access to care in minority communities by examining the association between preventable hospitalization rates and racial/ethnic composition of the community during 1995-2005. Using HCUP data, the results indicated increases in barriers faced by minority adults in accessing primary care over time, with no similar evidence for the elderly subgroup.
