    Model for End-Stage Liver Disease (MELD)

    Estimates short-term survival in patients with end-stage liver disease for transplant planning.

    IMPORTANT

    MDCalc has recently streamlined the MELD calculator collection.

    On this page, you'll find the original MELD Score (Pre-2016), MELD Na (UNOS/OPTN), and MELD 3.0. MELD Na is the current standard calculation for organ transplantation consideration in the United States.  MELD 3.0 better accounts for disparities in organ allotment based on sex. 

    When to Use
    Pearls/Pitfalls
    Why Use
    • Determines prognosis and prioritizes receipt of liver transplantation.

    MELD Na (UNOS/OPTN):

    • Primarily used to stratify patients ≥12 years old on liver transplant waiting lists.
    • Predicts mortality in the following scenarios: (a) after transjugular intrahepatic portosystemic shunt (TIPS), (b) cirrhotic patients undergoing non-transplantation surgical procedures, (c) acute alcoholic hepatitis, and (d) acute variceal hemorrhage.
    • Values should be no more than 48 hours old.
    • MELD can be used on any patient with end stage liver disease irrespective of cirrhosis etiology.

    MELD Na (UNOS/OPTN):

    • The MELD Score predicts three-month survival in patients (age 12+) with liver cirrhosis.
    • Scores range from 6 to 40, with higher scores correlating with increased severity of liver dysfunction and higher three-month mortality.
    • Several conditions are “standard MELD exceptions” and receive a different score (see Next Steps > Critical Actions):  hepatocellular carcinoma, hepatopulmonary syndrome, portopulmonary hypertension, familial amyloid polyneuropathy, primary hyperoxaluria, cystic fibrosis, hilar cholangiocarcinoma and hepatic artery thrombosis.
    • One of the exclusion criteria for the original data set was absence of acute reversible conditions such as spontaneous bacterial peritonitis or prerenal azotemia secondary to dehydration. Therefore, in principle, the score should only be applied after these reversible conditions have been treated, according to the authors (Kamath 2007).
    • MELD is the standard used by the Organ Procurement and Transplantation Network (OPTN) and determines who is the highest priority to receive liver transplants in the US.
    • It has been widely studied and validated.
