BACKGROUND: Discard rate of Public Health Service Increased Risk (PHS-IR) organs is high despite the absence of worse kidney transplant outcomes. METHODS: We conducted a retrospective, single-center study of PHS-IR kidney offers made to kidney transplant-only potential recipients from 6/2004 to 5/2015. Overall mortality and transplant outcomes between potential recipients were stratified by response to PHS-IR kidney offers. Cox regression and Kaplan-Meier analyses of mortality and allograft failure were performed. RESULTS: A total of 2423 potential recipients were offered a PHS-IR kidney, with 1502 transplanted, with or without a PHS-IR kidney. Predictors of accepting a PHS-IR kidney included higher Estimated Post Transplant Survival (EPTS) score, prior kidney transplant, and lower educational achievement on multivariable analysis (P = 0.025, P = 0.004, P = 0.023). A positive response to a PHS-IR kidney was associated with lower risk of mortality (3.63% vs 11.6%; aHR 0.467, P = 0.0008). PHS-IR kidney recipients had decreased risk of allograft loss compared to non-PHS-IR recipients (P = 0.007), though mortality outcomes were not significantly different based on PHS-IR status (P = 0.38). No transmission of HIV, HBV, or HCV occurred from PHS-IR kidney donors in this cohort. CONCLUSIONS: Efforts must be made to increase awareness of the beneficial outcomes of PHS-IR organs to maximize appropriate donor allocation.
