Welten Miko Yu Sumit Mohan Joel T. Adler Clinical Transplantation ABSTRACTIntroductionHow offer notifications are distributed early in the kidney allocation timeline, including how widely they are offered, is unclear. A better understanding of offer notification practices across organ procurement organizations (OPOs) may identify opportunities for more efficient allocation.MethodsWe merged the Scientific Registry of Transplant Recipients potential transplant recipient file with additional offer notification time stamps to identify 54 631 deceased‐donor kidney match runs from 2017 to 2023. Offer notifications for a given match run are sent to candidates/centers in “batches.” We quantified the number of offers in the initial batch—which theoretically reflects the OPO's initial estimate of how widely a kidney should be offered—and compared this metric across OPOs.ResultsKidneys were offered to a median of 14 candidates (IQR 9–38) in the first batch of notifications, and this varied across OPOs from 3 to 746 candidates per initial batch. Batch size at the OPO‐level did not correlate with rank at kidney placement or OPO nonuse rate. OPOs in the highest quartile of batch size sent more offers (median 100) than presumably necessary to place kidneys (median rank at placement 21), and OPOs in the lowest quartile of batch size sent fewer offers (6) than needed to place kidneys (rank at placement 19).ConclusionsOffer notification practices vary widely across OPOs, and many OPOs offer kidneys far more widely than necessary for placement. Optimization of offer notification practices may reduce unnecessary communications. Further research into allocation processes is needed to identify opportunities to improve efficiency of allocation for OPOs and transplant centers. 10.1111/ctr.70024 http://onlinelibrary.wiley.com/termsAndConditions#vor |
