On the first year after the implementation of MELD, these patients arbitrarily received a MELD score of 29, which was changed to a MELD score of 24 in the second year after the implementation of MELD.
The candidates were divided into the pre-MELD group for those listed from July 2007 to December 2005 and the post-MELD group for those listed from July 2006 to December 2012.
The patients with hepatocellular carcinoma (HCC) according to the Milan criteria were granted additional MELD points.
The implementation of the MELD score resulted in a shorter waiting time until liver transplantation.
Additionally, there was a significant effect on the waitlist dynamics in the first 4 years; however, the curves diverge from there, implying a null long-range effect on the waitlist by the MELD scores.
Until July 15, 2006, the time on the waiting list was the main criterion for allocating deceased donor livers in the state of São Paulo, Brazil.
After this date, MELD has been the basis for the allocation of deceased donor livers for adult transplantation.After this date, MELD was the basis for the allocation of deceased donor livers for adult transplantation.The MELD score primarily sought to increase access to transplantation for severely ill patients as a means to reduce the mortality rate of the waiting list patients.This calculation was performed by dividing the variables from Table 2. The transplantation rate decreased until 2005, increased dramatically thereafter, and peaked at approximately 50% in 2009/2010, dropping from there onwards.The increased mortality of patients waiting for a liver transplant and the shortage of donor organs induced efforts to improve the allocation criteria for liver transplantation candidates.The maximum acceptable value for serum creatinine is 4 mg/d L.
