Allocation of cadaveric livers for transplantation in the United States is now based on the severity of illness as determined by the model for end‐stage liver disease (MELD) score, a function of bilirubin, creatinine and international normalized ratio (INR). The aim of our study was to determine the association of various pre‐transplant risk factors, including the MELD score, on patient survival after orthotopic liver transplantation (OLT). The medical records of 499 consecutive patients (233 female, 266 males, mean age 50.9 ± 10.6 years) undergoing cadaveric OLT at our institution between June 1990 and February 1998 were reviewed. In the 407 patients alive at the latest contact, follow‐up was 4.7 years, with a minimum of 20 months (maximum of 9.4 years). Variables considered for analysis included MELD score, age, pre‐transplant renal dysfunction requiring dialysis, Child–Pugh classification, underlying liver disease, diabetes mellitus, and heart disease (ischemic/valvular/other). There were 92 deaths during follow‐up. In univariate analysis, the MELD score, renal failure requiring hemodialysis pre‐OLT, age > 42 years, and underlying etiology of liver disease were significantly associated with death during long‐term follow‐up. In multivariate models, age, underlying etiology of liver disease and renal failure requiring hemodialysis were independent predictors of death after OLT.
