An important metric of liver transplantation outcome is not readily available: acceptance of organ offers. A recent study (E Mitchell et al. Liver Transplantation 2018; 24: 803-809) showed a great deal of variability among pediatric liver transplantation centers in this metric.
The authors examined data from 2007-2015 with 4088 unique patients and 27,094 match runs. The range in organ acceptance rates was 5.1% to 14.6% with a median of 8.9%.
- “Center-level acceptance rates were associated with wait-list mortality, with a >10% increase in the risk of wait-list mortality for every 1% decrease in a centers adjusted liver offer acceptance rate (odds ratio, 1.10, CI 1.01-1.19)
As noted in a previous post, Pediatric Liver Transplantation -Past Time to Split, larger centers generally have higher acceptance rates.
My take: This study adds to the literature regarding the inequities that some patients unknowingly face when listed in some centers.

Those listed before age 6 months and with higher MELD scores (>20) were at increased risk. Recognition of these factors may help improve allocation.
