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.

Disparities in United States hospitalizations for serious infections in patients with and without opioid use disorder: a nationwide observational study.
This study examined the differences in patients with and without opioid use disorder (OUD) who were hospitalized for serious infections focusing on infective endocarditis, epidural abscess, septic arthritis or osteomyelitis. The authors used the 2016 National Inpatient Sample to examine differences in length of stay (LOS), discharge disposition, and charges. Patients with OUD had a lower probability of discharge at any given LOS, and lower odds of discharge to home with higher odds of discharge to a post-acute care facility. There were no significant differences in average total hospital charges.

Adults with diabetes residing in "food swamps" have higher hospitalization rates.
This study examined the relationship between ‘food swamps’ and hospitalization rates among adults with diabetes. Food Swamps are defined and measured by a ratio of fast food outlets to grocery stores within a given area. Data resources for this study included the Blue Cross Blue Shield Association Community Health Management Hub(R), AHRQ’s Health Care Cost and Utilization Project State Inpatient Databases, and HHS’s Area Health Resources File. The study concludes that higher hospitalization rates among adults with diabetes are significantly associated with food swamps, more so in rural than urban communities, and that improvements to local food environments may help to reduce this disparity.

Infectious disease hospitalizations among American Indian/Alaska native and non-American Indian/Alaska native persons in Alaska, 2010-2011.
The researchers used a merged state database to determine infectious disease (ID) hospitalization rates among American Indian/Alaska native (AI/AN) and non-American Indian/Alaska native persons in Alaska. They concluded that a substantial disparity in ID hospitalization rates exists between AI/AN and non-AI/AN persons, and the most common reason for ID hospitalization among AI/AN persons was lower respiratory tract infection.

Costs of care for hospitalization for pemphigus in the United States.
The purpose of this study was to determine the incidence of and risk factors for hospitalization with pemphigus and cost of care. It concluded that there is a significant inpatient burden for pemphigus in the United States. Moreover, there appear to be racial/ethnic and health care disparities with respect to pemphigus, such that poor, nonwhite, and/or uninsured or underinsured patients have higher odds of hospitalization.

Ethnic differences in potentially preventable hospitalizations among Asian Americans, Native Hawaiians, and other Pacific Islanders: implications for reducing health care disparities.
This study aimed to produce reliable estimates of health care quality among Native Hawaiian (NH), Other Pacific Islander (PI), and Asian American (AA) small population subgroups. Results showed that, despite efforts to reduce racial/ethnic health care disparities, significant gaps remain in potentially preventable hospitalization rates.
