Abstract

Insights

Urgent liver transplant candidates with a MELD score ≥30 face longer waits in Italy’s Southern Macro Area (SMA) compared to the Northern Macro Area (NMA). This study suggests a nationwide program is needed to improve transplant access for these critical patients.

Area of Science:

  • Transplant Medicine
  • Organ Allocation Systems
  • Hepatology

Background:

  • Patients with an urgent MELD score ≥30 in Italy are managed by a macro area-based system (Northern Macro Area - NMA, Southern Macro Area - SMA).
  • This system divides Italy into two main regions for managing liver transplant recipients with critical scores.

Purpose of the Study:

  • To evaluate the feasibility and necessity of transitioning the MELD score ≥30 macro area-based program to a nationwide system.
  • To analyze disparities in liver transplant access for patients with urgent MELD scores between Italy's NMA and SMA.

Main Methods:

  • Retrospective analysis of urgent MELD score ≥30 liver transplant requests from August 2014 to August 2015.
  • Comparison of waiting list times, request fulfillment rates, and unmet requests between the NMA and SMA.

Main Results:

  • A total of 132 requests were handled; 98 from NMA and 34 from SMA.
  • The NMA had significantly shorter average waiting list times (2.74 ± 2.29 days) compared to the SMA (4.5 ± 3.98 days).
  • Transplant fulfillment rates were higher in the NMA (80.4%) than in the SMA (55.5%), with significantly longer waiting times for unmet requests in the SMA (5.78 ± 4.59 days).

Conclusions:

  • Significant disparities exist in liver transplant waiting times and access between Italy's NMA and SMA for patients with MELD scores ≥30.
  • The increased mortality risk associated with longer waiting times necessitates consideration of a nationwide transplant program.
  • Transitioning to a national program could improve equity and timely access to liver transplantation for critically ill patients.
