Racial differences in low value care among older adult Medicare patients in US health systems: retrospective cohort study.
The objective of this retrospective cohort study was to characterize racial differences in receipt of low-value care among older Medicare beneficiaries overall and within U.S. health systems. Medicare fee-for-service administrative data was used for Black and White Medicare patients who were at least 65 as of 2016. Findings showed that, of the 40 low value services examined, Black patients had a higher adjusted receipt of 9 services and lower receipt of 20 services than White patients. Differences were generally small and largely due to differential care within health systems, but the authors concluded that their findings suggested potential factors that researchers, policymakers, and health system leaders might investigate to improve health care quality and equity.

Racial-ethnic composition of primary care practices and Comprehensive Primary Care Plus initiative participation.
The purpose of this study was to explore whether primary care practices serving high rates of Black or Latino Medicare fee-for-service (FFS) beneficiaries were less likely to participate in CPC+ in 2021 compared to practices serving lower rates of these same populations. 11,718 primary care practices and 7,264,812 attributed Medicare FFS beneficiaries across 18 eligible regions participated in the study. The study found that 26.9% of the eligible practices were CPC+ participants. In statistically adjusted analyses, primary care practices with high shares of Black and Latino beneficiaries had a lower likelihood of participating in CPC+ compared to practices with lower shares of these beneficiary groups. Participation disparities for practices with relatively high shares of Black beneficiaries partially explained state differences in CPC+ participation rates but did not explain participation disparities for practices with relatively high shares of Latino beneficiaries.

Health care use and outcomes in assisted living communities: race, ethnicity, and dual eligibility.
The purpose of this study was to examine the type and quality of care received in residential long-term care setting by racial/ ethnic minorities or residents eligible for dual Medicare and Medicaid. With 2018 Medicare data, the researchers identified 255,564 fee-for-service Medicare beneficiaries over the age of 55 who were living in 24,108 assisted living facilities across the United States and evaluated the relationship between race/ethnicity and dual status with emergency room use, inpatient hospital admission, 30-day readmission, and placement in a nursing home. The study found variations within and across assisted living facilities for racial/ethnic minority and dual residents, suggesting that outcome disparities are the most significant by dual eligibility status instead of only race/ ethnicity. The researchers concluded that these results can be used to inform and guide future research, as well as healthcare providers and policy makers.

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 hospitalization outcomes among Medicare beneficiaries during the COVID-19 pandemic.
This study assessed assess racial and ethnic differences in hospitalization outcomes during the COVID-19 pandemic among Medicare beneficiaries. Medicare claims from the Social Security Administration was used to determine in-hospital mortality and mortality inclusive of discharges to hospice and discharges to postacute care. Over 31 million Medicare recipients in the database were analyzed with over 14 million hospitalizations from January 2019 to February 2021. There was a decline in non-COVID-19 and an emergence of COVID-19 hospitalizations among beneficiaries of different racial and ethnic minority groups through February 2021. In-hospital mortality was not significantly different among Black patients relative to White patients but was 3.5 percentage points higher among Hispanic patients and other racial and ethnic minority groups. There were disparities in discharges to hospice and postacute care as well.

Use and disparities in parathyroidectomy for symptomatic primary hyperparathyroidism in the Medicare population.
The investigators’ objective was to determine national usage and disparities in parathyroidectomy for symptomatic primary hyperparathyroidism among insured older adults. Data was obtained using Medicare claims. They found that parathyroidectomy was underused and recommended that quality improvement efforts, rooted in equitable care, be undertaken to increase access to parathyroidectomy for this disease.

Beyond Black and White: mapping misclassification of Medicare beneficiaries race and ethnicity.
This study examined state-level variation in racial/ethnic misclassification of race and ethnicity in the Centers for Medicare and Medicaid Services administrative database using the enrollment database (EDB) beneficiary race code and the Research Triangle Institute (RTI) race code. The cohort included 4,231,370 Medicare beneficiaries who utilized home health care services in 2015. The authors found substantial variation between states in misclassification of self-identified Hispanic, Asian American/Pacific Islander, and American Indian/Alaska Native beneficiaries.

Medicare Advantage plan double bonuses drive racial disparity in payments, yield no quality or enrollment improvements.
Using national data for 2008-18, investigators found that double bonuses were not associated with either improvements in plan quality or increased Medicare Advantage enrollment. Additionally, double bonuses increased payments to plans to care for Black beneficiaries by $60 per year, compared with $91 for White beneficiaries. These findings suggest that double bonuses not only fail to improve quality and enrollment but also foster a racially inequitable distribution of Medicare funds that disfavors Black beneficiaries. This study supports eliminating double bonuses, thereby saving Medicare an estimated $1.8 billion per year.

Association of Medicare Advantage Star Ratings with racial, ethnic, and socioeconomic disparities in quality of care.
This cross-sectional study looked at racial/ethnic minority and socioeconomic disparities in ratings for Medicare Advantage (MA) plans, which disproportionately enroll these populations. A total of 1,578,564 enrollees were included in this analysis that used 22 measures of quality and satisfaction at the individual enrollee level, aggregated into simulated star ratings from 2-5 stratified by socioeconomic status (SES) and race/ethnicity. Low SES enrollees had simulated stratified star ratings 0.5 stars lower than individuals with high SES in the same contract. Black enrollees had simulated star ratings that were 0.3 stars lower and Hispanic enrollees had 0.1 lower simulated star ratings than White enrollees in the same contract. There was a larger difference in ratings with 4.5 to 5-star contracts with Black and Hispanic enrollees with Whites, and no statistical difference in 2.0 to 2.5 star-rated contracts. There was only low correlation between simulated ratings for enrollees of low SES and high SES.

Timing of home health care initiation and 30-day rehospitalizations among Medicare beneficiaries with diabetes by race and ethnicity.
Older adults with diabetes are at elevated risk of complications following hospitalization. Home health care services mitigate the risk of adverse events and facilitate a safe transition home. In the United States, when home health care services are prescribed, federal guidelines require they begin within two days of hospital discharge. This study examined the association between timing of home health care initiation and 30-day rehospitalization outcomes in a cohort of 786,734 Medicare beneficiaries following a diabetes-related index hospitalization admission during 2015.

Racial and ethnic disparities in care for health system-affiliated physician organizations and non-affiliated physician organizations.
The purpose of this study was to assess racial and ethnic disparities in care for Medicare fee-for-service (FFS) beneficiaries and whether disparities differ between health system-affiliated physician organizations (POs) and nonaffiliated POs. The investigators found no evidence that system-affiliated POs had smaller racial and ethnic disparities than nonaffiliated POs. Where differences existed, disparities were slightly larger in affiliated POs.

Proportion of racial minority patients and patients with low socioeconomic status cared for by physician groups after joining accountable care organizations.
The purpose of this study was to test for changes in the percentage of racial minority patients and patients with low socioeconomic status cared for by physician groups after joining an accountable care organization (ACO). This cohort study’s subjects consisted of a 15% random sample of Medicare fee-for-service beneficiaries attributed to physician groups. ACO file were used to determine Medicare Shared Savings Program (MSSP) participation. No changes were found in the proportions of vulnerable patients cared for by ACO-participating physician groups after joining an ACO compared with changes among nonparticipating groups.

Validity of race and ethnicity codes in Medicare administrative data compared with gold-standard self-reported race collected during routine home health care visits.
The authors compared the validity of two race/ethnicity variables found in Medicare administrative data against a gold-standard source also available in the Medicare data warehouse. They found that the race/ethnicity variables contained in Medicare administrative data for minority health disparities research can be improved through the use of self-reported race/ethnicity data. They conclude that future work to improve the accuracy of Medicare beneficiaries' race/ethnicity data should incorporate and augment the self-reported race/ethnicity data contained in assessment and survey data, available within the Medicare data warehouse.

Association of race/ethnicity with emergency department destination of emergency medical services transport.
The authors examined the patterns of emergency department (ED) destination of emergency medical services (EMS) transport according to patient race/ethnicity and compared the patterns between those transported by EMS and those who did not draw on EMS. Using Medicare claims data, they found race/ethnicity variation in ED destination for patients using EMS transport, with black and Hispanic patients more likely to be transported to a safety-net hospital ED compared with white patients living in the same zip code.

A national examination of long-term care setting, outcomes, and disparities among elderly dual eligibles.
The authors investigated the outcomes of expanding Medicaid funding for long-term care home and community-based services (HCBS). Using national Medicaid claims data on older adults enrolled in both Medicare and Medicaid, they found that overall hospitalization rates were similar for HCBS and nursing facility users. They concluded that home and community-based services need to be carefully targeted to avoid adverse outcomes and that the racial/ethnic disparities in access to high-quality institutional long-term care are also present in HCBS.

How have 30-day readmission penalties affected racial disparities in readmissions?: an analysis from 2007 to 2014 in five US states.
The purpose of this study was to examine changes in Black-White disparities in 30-day readmissions for acute myocardial infarction (AMI), congestive heart failure (CHF), or pneumonia following the passage and implementation of the Hospital Readmission Reduction Program (HRRP), and to compare disparities across safety-net and non-safety-net hospitals. Prior to the passage of HRRP, Black and White readmission rates and disparities in readmissions were decreasing, with largest reductions at safety-net hospitals. Findings showed that improvements in readmissions have not reversed following the implementation of HRRP. In contrast, disparities continue to persist at non-safety-net hospitals.

Examining black-white disparities among Medicare beneficiaries in assisted living settings in 2014.
The purpose of this study examined racial differences among a national cohort of assisted living (AL) residents and how the racial variation among AL Medicare Fee-For-Service (FFS) beneficiaries compared to differences among community-dwelling and nursing home cohorts. Using the Medicare Master Summary Beneficiary File, researchers found that black patients were disproportionately represented in AL, younger, more likely to be Medicaid eligible, had higher levels of acuity, and more often lived in ALs with fewer whites and more patients with dual eligibility. Further, new black residents entered AL with higher rates of acute care hospitalizations and skilled nursing facility utilization. Further research is recommended.

Racial/ethnic differences in those accompanying Medicare patients to the doctor: insights from the 2013 Medicare current beneficiary's survey.
This study used multivariable models applied to Medicare Current Beneficiary's Survey Access to Care public use data in order to predict companion accompaniment to health care providers among Medicare beneficiaries; Chi square analyses compared, by race/ethnicity, who was accompanying patients and why. Black and Hispanic patients were more likely to be accompanied than whites. In all three groups, more than a third of patients brought someone with them to ‘take notes,’ ‘ask questions,’ and/or ‘explain things,’ but significantly more Hispanic patients brought a companion to ‘explain instructions,’ ‘translate,’ and/or to provide ‘moral support.’ The authors conclude that many Medicare beneficiaries are accompanied to doctors' appointments, particularly among minority racial/ethnic groups, and that this should be taken in consideration in healthcare policy and practice.

Sex and race differences in the utilization and outcomes of coronary artery bypass grafting among Medicare beneficiaries, 1999-2014.
The authors sought to evaluate how the use of coronary artery bypass grafting (CABG) and its outcomes have evolved in different sex and racial subgroups. Using Medicare data, they found that women and black patients had persistently higher CABG mortality than men and white patients, respectively, despite greater declines over the time period. The authors conclude that these findings indicate progress, but further progress is needed.

Effects of transitioning to Medicare Part D on access to drugs for medical conditions among dual enrollees with cancer.
This study evaluated the impact of transitioning from Medicaid to Medicare Part D drug coverage on the use of noncancer treatments among dual enrollees with cancer. Its findings suggest that the removal of drug caps under Part D had a modest impact on the treatment of hypercholesterolemia overall and may have reduced white-black gaps in the use of lipid-lowering and antidepressant therapies.

Access to medications for Medicare enrollees related to race/ethnicity: results from the 2013 Medicare Current Beneficiary Survey.
Prescription medications are taken by millions of Americans to manage chronic conditions and treat acute conditions. These medications, however, are not equally accessible to all. The purpose of this study was to examine medication access by race/ethnicity among Medicare beneficiaries. The authors found that possible interventions for non-Hispanic blacks might include assisting them in finding the best drug plan to meeting their needs, connecting them to medication assistance programs, and discussing convenience of pharmacy with patients.
