title: Impact of the model for end-stage liver disease score on mortality after liver transplantation.
abstract: OBJECTIVE
  The objective of this study was to analyze survival, and mortality, rates as well as its causes during the month following liver transplantation with respect to the model for end-stage liver disease (MELD) model.
  
  
  METHODS
  We reviewed the mortality at 24 and 48 hours as well as 1 and 4 weeks of 380 transplanted patients over the past 7 years with regard to the MELD score.
  
  
  RESULTS
  The mean patient age was 55 years. Among subjects with MELD score ≤ 15 (n = 142; 37.36%), there were 34 deaths (23.94%), including 7 (4.92%) who died during the first month. The mean cause of death during this period was hemorrhage (n = 3; 8.8%). Among those with MELD scores between 16 and 18 (n = 76; 20%), the mortality rate increased to 23.68% (n = 18), including 3 who died during the first month (3.94%) with 1 case due to hemorrhage. Among the cohort with MELD scores between 19 and 21 (n = 78; 20.52%), 25 (32.05%) died, including 9 during the first month (11.53%). The most frequent cause of death was septic shock (n = 5; 20%). The mortality rate among patients with a MELD score between 22 and 24 was 22% (n = 11), of which 8% (n = 4) died in the month. The mean cause of death during this period was multiple organ dysfunction (n = 2; 18.1%). The patient group with a MELD score >24 had a 32.3% mortality rate (n = 11); 4 patients died during the first month following transplantation (11.76%). The most frequent cause of death was hemorrhage (n = 2; 18.1%).
  
  
  CONCLUSIONS
  Survival during the first month did not seem to be related to the MELD score at the time of transplantation, nor did we observe a direct correlation between the MELD score and the overall risk of mortality.
