AbstractNonstandard exceptions requests (NSERs), in which transplant centers appeal on a case-by-case basis for Pediatric End-Stage Liver Disease/Mayo End-Stage Liver Disease points, have been highly utilized for pediatric liver transplant candidates. We evaluated whether NSE outcomes are associated with waitlist and posttransplant mortality. United Network for Organ Sharing (UNOS) Scientific Registry of Transplant Recipients data on pediatric liver transplant candidates listed in 2009-2014 were analyzed after excluding those granted automatic UNOS exceptions. Of 2581 pediatric waitlist candidates, 44% had an NSE request. Of the 1134 children with NSERs, 93% were approved and 7% were denied. For children 2-18 years at listing, NSER denial increased the risk of waitlist mortality or removal for being too sick (subhazard ratio 2.99, 95% confidence interval [CI] 1.26-7.07, p = 0.01 in multivariate analysis). For children younger than 2 years, NSER denial did not impact waitlist mortality/removal. Children with NSER approved had reduced risk of graft loss 3 years posttransplant in univariate but not multivariable analysis (odds ratio 0.73, 95% CI 0.53-1.01, p = 06). Those with NSER denial had a higher risk of posttransplant death than those with no NSER (hazard ratio 2.43, 95% CI 0.99-5.95, p = 0.05, multivariable analysis), but NSER approval did not impact posttransplant death. Further research on NSER utilization in pediatric liver transplant is needed to optimize organ allocation and outcomes for children.© Copyright 2016 The American Society of Transplantation and the American Society of Transplant Surgeons.
