About this study

Intro: The present clinical research protocol is part of the LEOPARD European project (Grant n° 101080964 Horizon Europe) which aims to design and validate new predictive models of mortality among liver transplantation (LT) candidates. MELD based-liver graft allocation systems have become increasingly inaccurate over the last decade to predict mortality/dropout of liver transplantation (LT) candidates on the waitlist (WL). Wide disparities in mortality/dropout on the WL also exist across European countries, ranging from 5 to 30% according to transplantation indications and countries. In this setting, the European Commission- Horizon Europe funded-LEOPARD project intends to design new, 2nd generation, AI-machine learning-based predictive models of delisting in LT candidates, to better serve on time patients with the highest risk of dropout on the WL and to improve equity of access to LT across Europe. Hypothesis/Objective: The scientific justification of the LEOPARD TVDCS is therefore to collect a large set of data in liver transplantation candidates listed in Europe a) to design and b) to validate LEOPARD 2nd generation AI-based predictive models of mortality/dropout The primary objective is to develop new predictive models of mortality/drop out on the waitlist in patients with decompensated cirrhosis, or other end-stage chronic liver diseases, and in patients listed for Hepato-cellular carcinoma (HCC). Method: Longitudinal multicenter prospective health care data collec…
