Important: Inputs must be complete to perform calculation.


MELD 3.0 score excluding albumin
90-day survival estimation
60-day survival estimation
30-day survival estimation

Notes

The MELD 3.0 score accounts for intrinsic differences in Serum creatinine between females and males.
In previous iterations of MELD, these differences might bias the calculation and interpretation by resulting in lower MELD scores in females than males with otherwise identical risk factors.
If a patient has not received intravenous albumin infusions, consider using the MELD 3.0 score including serum albumin calculator.
For more information on the use of the MELD 3.0 score in organ allocation, please refer to UpToDate topics that discuss the management of liver failure.

Equations used

MELD 3.0 score excluding albumin = (Round the following expression to the nearest integer)(Sex + (4.85 * ln(Total bilirubin)) + (0.88 * (137 - Serum sodium)) - (0.25 * (137 - Serum sodium) * ln(Total bilirubin)) + (9.66 * ln(INR)) + (10.47 * ln(Serum creatinine)) + 6)

90-day survival estimation = 100 * 0.946^{e^{(0.17698*MELD 3.0 score excluding albumin-3.56)}}

60-day survival estimation = 100 * 0.963^{e^{(0.17698*MELD 3.0 score excluding albumin-3.56)}}

30-day survival estimation = 100 * 0.981^{e^{(0.17698*MELD 3.0 score excluding albumin-3.56)}}

Calculation details and variables

Total bilirubin, Serum creatinine, and INR values are set to 1 if measured values are less than 1.
Serum creatinine is set to 3 mg/dL for all measured values >3 mg/dL.
Serum sodium is similarly bound 125-137 mEq/L.
Serum albumin is similarly bound 1.5-3.5 g/dL.

Equation parameters, such as Sex, have 2 or more discrete values that may be used in the calculation. The numbers in the parentheses, eg, (1.4), represent the values that will be used.
