Notes
  • The model for end-stage liver disease (MELD) score is used to estimate relative disease severity in adult patients.
  • If a patient has had 2 or more hemodialysis treatments or ≥24 hours of CVVHD in the week prior to the time of the scoring, Creatinine will be set to 353.6 mcmol/L, which is the maximum creatinine level allowed in the model.
  • The default setting for the choice "Hemodialysis twice or ≥24 hours of CVVHD in the past week" is "No."
  • For patients with hepatocellular carcinoma, the MELD score is increased according to an algorithm established by the United Network for Organ Sharing (UNOS).
  • INR: international normalized ratio; CVVHD: continuous venovenous hemodialysis.
  • Please refer to appropriate UpToDate topic reviews for further information.
  • * This calculator uses SI units (Système international d'unités) as the default for inputs. Do not use this calculator if you are using conventional units (also known as US units and gravimetric units); please refer instead to the conventional units version of this calculator.

 
Equations used
 
MELD_score = (Round the following expression to the nearest integer)((9.57 * ln(Creatinine/88.4)) + (3.78 * ln(Bilirubin/17.1)) + (11.2 * ln(INR)) + 6.43)

 

 
Only digits 0 to 9 and a single decimal point (".") are acceptable as numeric inputs. Attempted input of other characters into a numeric field may lead to an incorrect result.
