Race/Ethnicity and 30-Day Readmission Rates in Medicare Beneficiaries With COPD.

COPD is now included in Medicare's hospital readmission reduction program. Hospitals with excessive risk-adjusted 30-d readmission rates receive financial penalties. Race/ethnicity is not included in the risk-adjustment models. We examined whether race/ethnicity was independently associated with readmission after controlling for clinical factors and other demographic variables. We used the 100% Medicare in-patient (Part A) files to identify patients hospitalized with COPD (MS-DRG codes 190, 191, 192) who were discharged between January 1, 2013, and September 13, 2014. The outcome measure was an unplanned readmission within 30 d of hospital discharge. We used generalized linear mixed models to test the independent effects of race/ethnicity on 30-d readmission. The sample included 298,706 Medicare beneficiaries hospitalized for COPD: 87% white, 8% African-American, and 5% Hispanic. Mean age was 77.7 ± 7.7 y. Overall, 17.3% of subjects experienced an unplanned readmission. Whites (17.4%) and African-Americans (17.7%) had significantly higher unadjusted rates than Hispanics, and Hispanics demonstrated the lowest readmission rate (16.3%). The minority groups generally displayed higher-risk clinical profiles. After controlling for those differences, the multivariable model suggested a benefit for both minority groups in terms of readmission risk. The adjusted readmission rates for whites, African-Americans, and Hispanics were 16.6%, 15.9%, and 14.6%, respectively. Racial/ethnic disparities in observed readmission rates may be largely explained by the more severe clinical profiles of minority populations. Controlling for known clinical risk factors effectively mediates the relationship between race/ethnicity and readmission.

Sex and racial/ethnic differences in the reason for 30-day readmission after COPD hospitalization.

Reduction of 30-day readmissions in patients hospitalized for chronic obstructive pulmonary disease (COPD) is a national objective. However, there is a dearth of research on sex and racial/ethnic differences in the reason for 30-day readmission. We conducted a retrospective cohort study using 2006-2012 data from the State Inpatient Database of eight geographically-diverse US states (Arkansas, California, Florida, Iowa, Nebraska, New York, Utah, and Washington). After identifying all hospitalizations for COPD made by patients aged ≥40 years, we investigated the primary diagnostic code for all-cause readmissions within 30 days after the original COPD hospitalization, among the overall group and by sex and race/ethnicity strata. Between 2006 and 2012, there was a total of 845,465 COPD hospitalizations at risk for 30-day readmissions in the eight states. COPD was the leading diagnostic for 30-day readmission after COPD hospitalization, both overall (28%) and across all sex and race/ethnicity strata. The proportion of respiratory diseases (COPD, pneumonia, respiratory failure, and asthma) as the readmission diagnosis was higher in non-Hispanic black (55%), compared to non-Hispanic white (52%) and Hispanics (51%) (p < 0.001). The proportion of asthma as the readmission diagnosis differed significantly by sex (6% in men and 9% in women; p < 0.001). Similarly, the proportion of asthma also differed significantly by race/ethnicity (5% in non-Hispanic white, 16% in non-Hispanic black, 15% in Hispanics, 13% in others; p < 0.001). In this analysis of all-payer population-based data, we found sex and racial/ethnic differences in the reason for 30-day readmission in patients hospitalized for COPD.

Racial Disparities in Readmission Rates among Patients Discharged to Skilled Nursing Facilities.

Prior studies have reported mixed findings about the existence of racial disparities in readmission rates among Medicare Advantage beneficiaries, but these studies used data from one state, focused on black-white disparities, and did not focus on patients discharged to skilled nursing facilities (SNFs). The objective of the study was to characterize racial and ethnic disparities in rates of 30-day rehospitalization directly from SNFs among fee-for-service and Medicare Advantage patients. A cross-sectional study of admissions to SNFs in 2015 was conducted. SNFs across the United States. The sample included 1 500 334 white, 213 848 African American, and 99 781 Hispanic Medicare patients who were admitted to 13 375 SNFs. The main outcome of interest was readmission, identified as patients sent back to any hospital directly from the SNF within 30 days of admission, as indicated on the Minimum Data Set discharge assessment. Overall readmission rates for fee-for-service patients were 16.7% (95% confidence interval [CI] = 16.7%-16.8%) for whites, 18.8% (95% CI = 18.7%-19.0%) for African Americans, and 17.4% (95% CI = 17.1%-17.7%) for Hispanics. Readmission rates in Medicare Advantage were 14.7% (95% CI = 14.5%-14.8%) for whites, 16.8% (95% CI = 16.6%-17.1%) for African Americans, and 15.3% (95% CI = 14.9%-15.6%) for Hispanics. We also found that African Americans had about 1% higher readmission rates than whites, even when they received care within the same SNF. No statistically significant differences were found in the magnitude of within-SNF racial disparities in Medicare Advantage compared with Medicare fee-for-service. We found racial disparities in readmission rates even within the same facility for both Medicare Advantage and fee-for-service beneficiaries. Intervention to reduce disparities in readmission rates, as well as more comprehensive quality measures that incorporate outcomes for Medicare Advantage enrollees, are needed.
