The data were related to the actual number of liver transplantations (Tr), the incidence of new patients on the list (I), and the number of patients who died while being on the waitlist (D) from 1997 to 2005 (the pre-MELD era) and from 2006 to 2012 (the post-MELD era).The number of transplantations from 1997 to 2005 and from 2006 to 2012 increased nonlinearly, with a clear trend to levelling to equilibrium at approximately 350 and 500 cases per year, respectively.
MELD was calculated at the time of transplantation, as previously described , using the following objective variables: the serum creatinine, bilirubin, and INR levels.
The minimum acceptable value for INR, creatinine, and bilirubin is 1.
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.
The introduction of the MELD score had a significant effect on the waitlist dynamics in the first 4 years after its introduction; however, the curves diverge from there, implying a null long-range effect by the MELD scores on the waitlist (Figure 3).
