National and regional analysis of exceptions to the Pediatric End-Stage Liver Disease scoring system (2003-2004).
Since February 2002, the Pediatric End Stage Liver Disease (PELD) scoring system has been utilized as a means of prioritizing children for liver transplantation. The United Network for Organ Sharing database was queried to assess utilization of PELD in 2003 and 2004; 682 liver transplants were performed in pediatric recipients where the PELD score was potentially the primary determinant of liver allocation. In the majority of circumstances (53%) the actual calculated PELD score was not utilized to determine liver allocation. An exception to the PELD score was utilized in 24% of cases. An additional 29% of the children were listed as urgent (status 1) without having acute liver failure. There was considerable regional variability in the inability to utilize actual PELD scores for liver allocation to children. PELD utilization was higher in regions of the country where pediatric donor organs were more available, presumably because children have some priority for organs from pediatric donors. There were 87 deaths in children awaiting liver transplantation. The mean PELD score in children without acute liver failure or metabolic liver disease (n = 33) near the time of death was 24.2, which has a purported 3-month risk of mortality of less than 10%. In our opinion the assigned 3-month risk of mortality associated with PELD scores is understated. Three-month mortality risk is used to inter-convert the adult and pediatric scoring systems. Therefore exceptions to the scoring system are required when children compete with adults for donor organs. In conclusion, urgent reassessment of the PELD scoring system is needed to avoid morbidity and mortality in children.
