Wait Time Modifications for Black Transplant Candidates Affected by Race-Based Kidney Function Estimation

How did national kidney transplant rates change after the implementation of wait time modifications for Black candidates affected by race-based kidney function estimation?From January 2023 through June 2025, a total of 21 119 modification recipients were allocated 51 061 person-years of waitlist time. In interrupted time series analyses, policy implementation was associated with an increase of 5.3 transplants per 1000 Black candidate listings, with significant increases among preemptive and postdialysis candidates and without significant changes in living donor transplant rates or transplant rates among non-Black and/or Hispanic candidates.A national policy intervention to retrospectively remedy the harms of race-based kidney function equations was associated with increased transplant rates among Black candidates.
