Abstract

Abstract: Background: MELD exceptions are designed to equipoise liver transplant waiting list survival. We aimed to analyze the impact of the MELD Upgrade rule and all other MELD exceptions on the liver transplant waiting list outcomes during 2012–2017 in Switzerland. Methods: We conducted a nationwide cohort study including all adult patients registered on the Swiss liver transplant waiting list between 2012 and 2017. Waiting list mortality and access to transplantation were analyzed, considering MELD exceptions as time-dependent covariates. Results: 730 patients were included. Patients with MELD Upgrade exceptions had a higher risk of dying while on the waiting list (OR 2.13; CI 95% 1.30–3.47) and also an increased likelihood of receiving a liver transplantation, when compared to patients without MELD exceptions. Patients with any type of MELD exceptions were more likely to be transplanted when compared to patients without MELD exceptions. The proportion of patients with MELD exceptions increased from 2012 to 2017 (44% vs 88%). Allocation MELD at the time of transplantation showed an annual increase (23 ± 8 points vs 32 ± 5 points, p < 0.001). Conclusion: Only patients with MELD Upgrade exceptions had the expected combination of higher waiting list mortality and quicker access to liver transplantation.
