Objectives: MELD, UKELD and D-MELD (donor age x MELD) have been assessed as scores for predicting survival after orthotopic liver transplantation (OLT), but with mediocre results. We introduced new indices based on preoperative MELD and UKELD scores, assessed their predictive ability concerning post-OLT survival, and compared it with that of the pre-existing scores.
Methods: We included 1017 OLTs from deceased donors that were performed in our department between 2008 (the year UKELD was introduced) and 2019. Data were collected about donor and recipient characteristics (including MELD and UKELD scores), and transplant characteristics and outcomes. The following scores were calculated: D-MELD, D-UKELD (donor age x UKELD), DR-MELD [(donor age+recipient age)xMELD], DR-UKELD [(donor age+recipient age)xUKELD]. Results: No score had predictive value concerning graft survival. Regarding patient survival, DR-MELD and DR-UKELD provided the best results, but with a low accuracy. The highest accuracy was observed at 1 year post OLT
