Changes in Racial Equity Associated With Participation in the Bundled Payments for Care Improvement Advanced Program.

IMPORTANCE: The Medicare alternative payment models are designed to incentivize cost reduction and quality improvement, but there are no requirements established for evaluating the outcomes of the Medicare populations.

OBJECTIVE: To examine whether participation in the Medicare Bundled Payments for Care Improvement Advanced (BPCI-A) program was associated with narrowing or widening of Black and White racial inequities in outcomes and access.

DESIGN, SETTING, AND PARTICIPANTS: Retrospective cohort alternative payment models on equity and quality for disadvantaged populations were studied between April 6, 2021, and August 28, 2022, in US hospitals. Black and White Medicare beneficiaries admitted for any of the 29 inpatient conditions in the BPCI-A program between January 1, 2017, and September 31, 2019, were included.

EXPOSURES: BPCI-A participation implemented in 2018.

MAIN OUTCOMES AND MEASURES: Ninety-day readmission and mortality, healthy days at home, and proportion of Black patients hospitalized. Segmented regression models were used to examine quarterly changes in slopes for each outcome.

RESULTS: The sample included 6 690 336 episodes (6 019 359 White patients, 670 977 Black patients). The population comprised approximately 43% men, 57% women, 17% individuals younger than 65 years, 47% between ages 65 and 80 years, and 36% older than 80 years. Prior to implementation of the BPCI-A program, compared with episodes for White patients, Black patients had higher 90-day readmissions (36.3% vs 29.6%), similar 90-day mortality (12.3% vs 13.3%), and fewer healthy days at home (mean, 68.5 vs 69.5 days). BPCI-A participation was not associated with significant changes in the racial gap in readmissions but was associated with a greater gain in heathy days at home (differences by race, -0.07 days per quarter; 95% CI, -0.12 to -0.01 days per quarter). Among Black patients admitted to BPCI-A hospitals vs controls, healthy days at home increased by 0.09 more days/episode per quarter (95% CI, 0.02-0.17 days/episode per quarter). The proportion of Black patients decreased similarly at BPCI-A and control hospitals.

CONCLUSIONS AND RELEVANCE: In this cohort study, BPCI-A participation was not associated with improvements in racial inequities in clinical outcomes. Black patients in BPCI-A had a slight gain in healthy days at home; there were no changes in access. The findings of this study suggest that more needs to be done if payment policy reform is going to be part of the efforts to address glaring racial inequities in health care quality and outcomes. These findings support a need for payment policy reform specifically targeting equity-enhancing programs.
