Liver transplantation in the high MELD era: a fair chance for everyone?

Introduction:
In 2006, the model for end-stage liver disease (MELD) was introduced in Germany. Recent data clearly show a decrease of mortality on the waiting list but also a decrease of post-liver transplant survival. Several factors are discussed to be responsible for that; although, a MELD >30 is known to be major risk factor for outcome, MELD scores have increased to over 30 since introduction of the MELD system. On the other hand, the quality of donor organs is deteriorating from year to year at the same time.
Results:
To date, we have to face the dilemma of organ allocation to significantly sicker patients resulting in a noticeably worsening of post-orthotopic liver transplant (OLT) results. The question is how to keep an acceptable standard of post-OLT results.
Conclusion:
Should allocation guidelines be modified? A further significant question is: How fair is the current allocation system for patients on the waiting list? Does the MELD score privileges or discriminates potential organ recipients?
Insights
The Model for End-Stage Liver Disease (MELD) system in Germany has reduced waiting list deaths but also lowered post-liver transplant survival. This raises questions about organ allocation fairness and the MELD score's impact.
Area of Science:
- Hepatology
- Transplant Surgery
- Public Health Policy
Background:
- The Model for End-Stage Liver Disease (MELD) was implemented in Germany in 2006.
- Post-MELD introduction, a decrease in waiting list mortality is observed, alongside a decline in post-liver transplant survival.
- Increasing MELD scores (above 30) and deteriorating donor organ quality are potential contributing factors.
Purpose of the Study:
- To address the dilemma of allocating organs to increasingly sicker patients.
- To investigate strategies for maintaining acceptable post-orthotopic liver transplant (OLT) outcomes.
- To evaluate the fairness and impact of the current MELD-based organ allocation system.
Main Methods:
- Analysis of liver transplant waiting list data.
- Evaluation of post-orthotopic liver transplant (OLT) survival rates.
- Assessment of organ donor quality trends.
Main Results:
- A decrease in liver transplant waiting list mortality.
- A noticeable worsening of post-orthotopic liver transplant (OLT) results.
- Rising MELD scores and declining donor organ quality observed concurrently.
Conclusions:
- The current organ allocation system, particularly the MELD score, may require modification.
- There are significant concerns regarding the fairness of the MELD system for patients awaiting liver transplants.
- Further investigation is needed to determine if the MELD score discriminates against certain potential organ recipients.
