Multicenter study of racial and ethnic inequities in liver transplantation evaluation: understanding mechanisms and identifying solutions.
This multicenter study examined racial and ethnic inequities in liver transplantation. The authors recruited participants from the liver transplantation (LT) teams including coordinators, advanced practice providers, physicians, social workers, dieticians, pharmacists, leadership at 2 major LT centers. They conducted 54 interviews and had 49 observation hours. They created a conceptual framework describing how transplant work system characteristics and other external factors may improve equity in the LT evaluation process. They proposed transplant center-level solutions (i.e., including but not limited to training of staff on health equity) to modifiable barriers in the clinical work system that could help patient navigation, reduce disparities, and improve access to care. Their findings call for an urgent need for transplant centers, national societies, and policy makers to focus efforts on improving equity (tailored, patient-centered resources) using the science of human factors and systems engineering.

Changes in preventive service use by race and ethnicity after Medicare eligibility in the United States.
Researchers examined whether widespread eligibility for Medicare at age 65 narrows disparate preventive service use by race and ethnicity. Using MEPS data and examining six preventive services, they found that, for non-Hispanic Black adults, preventive service use increased after age 65. Further, for all four preventive health measures that were lower for Hispanic adults compared with non-Hispanic White adults prior to age 65, service use was indistinguishable between these groups after reaching the Medicare eligibility age. They concluded that Medicare eligibility appeared to reduce most racial and ethnic disparities in preventive service use.

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.

Intersection of living in a rural versus urban area and race/ethnicity in explaining access to health care in the United States.
The researchers examined whether living in a rural versus urban area differentially exposes populations to social conditions associated with disparities in access to health care. They cocluded that rural status confers additional disadvantage for most of the health care use measures, independently of poverty and health care supply.

Help-seeking behavior and health care navigation by Bhutanese refugees.
The objective of this study was to document barriers to care, help-seeking behaviors, and the impact of a community-based patient navigation intervention on patient activation levels among Bhutanese refugees in the U.S. Following the intervention, only one-third reported the lowest level of patient activation and one-third were highly activated. Bhutanese refugees overcome healthcare access barriers by seeking help from a network of support that begins within the community.

Measuring geographic "hot spots" of racial/ethnic disparities: an application to mental health care.
The researchers identified geographic "hot spots" of racial/ethnic disparities in mental health care access. They identified these "hot spots": Richmond, Virginia, and Columbus, Georgia, for Black-White disparities; Fresno, California, and Dallas, Texas, for Latino-White disparities; and Riverside, California, and Houston, Texas, for Asian-White mental health care disparities. They discussed the potential and limitations of these methods as tools for understanding health care disparities in other contexts.

Healthcare access and utilization among Korean Americans: The mediating role of English use and proficiency.
This study examines whether English language use and proficiency plays a mediating role in the relationships between length of hospital stay in the US and health insurance coverage, access to, and use of care. Results show that health care utilization was primarily driven by having health insurance and a usual source of care. Recommendations include a focus on increasing English use and proficiency and insurance coverage among older, female, less educated Korean Americans to mitigate health disparities associated with reduced access to health services in this population.

The effects of telemedicine on racial and ethnic disparities in access to acute stroke care.
The authors sought to determine the effect of telemedicine on access to acute stroke care for racial and ethnic minorities in the state of Texas. They found that telemedicine increased access to acute stroke care for 1.5 million Texans, and they found no evidence of disparities in access to the acute stroke expertise afforded by telemedicine.

'Pharmacy deserts' are prevalent in Chicago's predominantly minority communities, raising medication access concerns.
The authors examined whether trends in the availability of pharmacies varied across communities in Chicago with different racial or ethnic compositions and whether "pharmacy deserts," or low-access neighborhoods, were more common in segregated black and Hispanic communities than elsewhere. They found that in 2012 there were disproportionately more pharmacy deserts in segregated black communities, as well as in low-income communities and federally designated Medically Underserved Areas. These findings suggest that public policies aimed at improving access to prescription medications may need to address factors beyond insurance coverage and medication affordability.

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.

Explaining racial and ethnic disparities in cholesterol screening.
This study examining the impact of low socioeconomic status, access to care, and language on racial and ethnic disparities in cholesterol screening found that these factors explained most of those disparities. After adjusting for these factors, disparities between whites and Blacks and Hispanics but not Asians and Pacific Islanders were eliminated.

Federal investments to eliminate racial/ethnic health-care disparities.
The authors presented a model that describes the relationships among social disadvantage, health-care disparities, and health disparities. They proposed that increasing the diversity of the public health and health-care workforces is an efficient strategy for reducing disparities because it impacts both access to care and patient-provider communication.
