    BackgroundManagement of patients on the kidney transplant waitlist lacks oversight, and transplant centers can delist candidates without consequence. To better understand between-center differences in waitlist management, we examined delisting rates and mortality after delisting within 3 years of removal from the kidney transplant waitlist.Study DesignThis is a retrospective cohort study using data from the Scientific Registry of Transplant Recipients of adults listed for deceased donor kidney transplant in 2015 and followed until the end of 2018. Patients of interest were those delisted for reasons other than transplant, death, or transfer. Centers were excluded if they had fewer than 20 waitlisted patients per year. We calculated probability of delisting and death after delisting using multivariable competing risk models.ResultsDuring follow-up, 14.2% of patients were delisted. The median probability of delisting within 3 years, adjusted for center-level variability, was 7.0% (interquartile range [IQR]: 3.9% to 10.6%). Median probability of death was 58.2% (IQR: 40% to 73.4%). There was no meaningful correlation between probability of delisting and death (τ = -0.05, p = 0.34).ConclusionsThere is significant variability in the rate of death after delisting across kidney transplant centers. Likelihood of transplant is extremely important to candidates, and improved data collection efforts are needed to inform whether current delisting practices are successfully removing patients who could not meaningfully benefit from transplant, or whether certain populations may benefit from remaining on the list and maintaining eligibility.Copyright © 2022 by the American College of Surgeons.
