Intermediate or intensive care unit admission across race and ethnicity.
This study’s aim was to assess the association between race and ethnicity and admission to intermediate (IMCUs) or intensive care units (ICUs) among hospitalized patients. Florida hospital discharge data from the State Inpatient Database was used to assess the relationship between race (White, Black, Other) and Hispanic ethnicity and IMCU or ICU admission. After controlling for demographics and comorbidities, the prevalence of IMCU or ICU admission was higher among non-Hispanic Blacks and non-Hispanic patients of other races compared with non-Hispanic Whites. The prevalence of IMCU or ICU use was lower among Hispanic Whites and Hispanics of other races compared with non-Hispanic Whites after controlling for other demographic characteristics and comorbidities.

Severe maternal morbidity and mortality risk at the intersection of rurality, race and ethnicity, and Medicaid.
Using maternal discharge records from childbirth hospitalizations in the HCUP National Inpatient Sample, 2007-15, researchers examined differences in rates of severe maternal morbidity and mortality by rural or urban geography, race and ethnicity, and clinical factors among Medicaid-funded births and privately insured hospital births. The highest rate of severe maternal morbidity and mortality occurred among rural Indigenous Medicaid-funded births; births among Black rural and urban residents and among Hispanic urban residents also experienced elevated rates. The researchers concluded that heightened rates of severe maternal morbidity and mortality among Medicaid-funded births indicate an opportunity for state and federal policy responses to address the maternal health challenges faced by Medicaid beneficiaries, including Black, Indigenous, and rural residents

New evidence on geographic disparities in United States hospital capacity.
The purpose of this study was to describe hospital capacity across the United States. The researchers combined American Hospital Association Survey, Hospital Compare, and American Community Survey data with the 2017 near-census of U.S. hospital inpatient discharges from the Healthcare Cost and Utilization Project (HCUP). The study found that 0.11 more beds per 1000 population were supplied to zip codes where Non-Hispanic individuals live than zip codes where non-Hispanic White individuals live. However, the hospitals supplying this capacity have 0.36 fewer staff per bed and perform worse on many care quality measures. Zip codes in the most urban parts of America have the least hospital capacity (2.11 beds per 1000 persons) from across the rural-urban continuum. While more rural areas have higher capacity levels, urban areas have advantages in staff and capital per bed. The researchers did not find systematic differences in care quality between rural and urban areas. The study concluded that lower hospital care quality and resource intensity plays a key role in racial, ethnic, and income disparities in hospital care related outcomes.

Impact of race/ethnicity and socioeconomic status on risk-adjusted hospital readmission rates following hip and knee arthroplasty.
This study examined the extent to which risk-adjusting for race/ethnicity and socioeconomic status affected hospital performance in terms of readmission rates following total hip arthroplasty (THA) and total knee arthroplasty (TKA). It found that inclusion of race/ethnicity and socioeconomic status in the risk-adjustment algorithm led to a relative-performance change in readmission rates following THA and TKA at less than 3 percent of the hospitals.

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.

Disparities in rates of inpatient mortality and adverse events: race/ethnicity and language as independent contributors.
The authors investigated inpatient mortality rates and obstetric trauma for self-reported speakers of English, Spanish, and languages of Asia and the Pacific Islands (API) and compared quality of care by language with patterns by race/ethnicity. They found that speaking a non-English principal language and having a non-White race/ethnicity did not place patients at higher risk for inpatient mortality, except for a higher stroke mortality for Japanese-speaking patients. Patients who spoke API languages or had API race/ethnicity had higher risk for obstetric trauma than English-speaking White patients, while Spanish-speaking Hispanic patients had more obstetric trauma than English-speaking Hispanic patients.

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.
