The Model for End-Stage Liver Disease (MELD) is a reliable measure of mortality risk in patients with end-stage liver disease. It is used as a disease severity index to help prioritize allocation of organs for transplant. The MELD Na adds the sodium to the calculation to better categorize patients with cirrhois with mortality. The MELD refit attempts to better model prediction of mortality.

Formula :

4.258×Loge (bilirubinC) + 6.792×Loge (creatinineC) + 8.290×Loge (INRC) + 0.652 × (140−NaC) − 0.194×(140−NaC) × LogeBiliCC + 6.327

Explanation of Result :

3 Month Mortality :

MELD score > 40 : 71.3% mortality
MELD score 30–39 : 52.6% mortality
MELD score 20–29 : 19.6% mortality
MELD score 10–19 : 6.0% mortality
MELD score < 9 : 1.9% mortality
