The Liver Transplant Program at the Charité Berlin

Area of Science:

• Hepatology
• Transplantation Surgery
• Public Health Policy

Background:

• Liver transplantation is a critical treatment for end-stage liver disease.
• The EUROTRANSPLANT region implemented a MELD-based allocation system in 2006 due to organ scarcity.
• Challenges include increased demand, limited donor organs, and use of extended criteria donors.

Purpose of the Study:

• To evaluate the impact of the MELD-based allocation system on liver transplant outcomes.
• To identify factors contributing to recent challenges in liver transplantation.
• To propose modifications to allocation algorithms and incentives.

Main Methods:

• Analysis of liver transplant data from the EUROTRANSPLANT region post-2006.
• Comparison of pre- and post-MELD system waiting list mortality and 1-year patient survival.
• Examination of changes in allocation thresholds (mean match-MELD).

Main Results:

• Waiting list mortality decreased from 20% to 10% after MELD implementation.
• 1-year post-transplant patient survival declined from 90% to below 80%.
• The mean match-MELD increased significantly from 25 to 34 in Germany.

Conclusions:

• While MELD-based allocation reduced waiting list mortality, it negatively impacted post-transplant survival.
• Economic pressures and resource limitations may contribute to suboptimal outcomes.
• Modifying allocation algorithms and incentives is crucial for improving liver transplant results.
