Decreased Utilization Rate of Grafts for Liver Transplantation After Implementation of Acuity Circle-based Allocation. Transplantation Bekki, Y., Myers, B., Tomiyama, K., Imaoka, Y., Akabane, M., Kwong, A. J., Melcher, M. L., Sasaki, K. 2023

Abstract

The allocation system for livers began using acuity circles (AC) in 2020. In this study, we sought to evaluate the impact of AC policy on the utilization rate for liver transplantation (LT).Using the US national registry data between 2018 and 2022, LTs were equally divided into 2 eras: pre-AC (before February 4, 2020) and post-AC (February 4, 2020, and after). Deceased potential liver donors were defined as deceased donors from whom at least 1 organ was procured.The annual number of deceased potential liver donors increased post-AC (from 10?423 to 12?259), approaching equal to that of new waitlist registrations for LT (n?=?12?801). Although the discard risk index of liver grafts was comparable between the pre- and post-AC eras, liver utilization rates in donation after brain death (DBD) and donation after circulatory death (DCD) donors were lower post-AC (P?
