The only criticism received by the model concerns the fact that it doesn’t have yet enough relevant validation. Survival chances change significantly, especially in the ranges of sodium change between 120 and 135 mEq/L, when a decrease in serum sodium of one unit corresponds to a 12% increase in mortality risk in the following 3 months. Hyponatremia is in general considered a predictor of early mortality, therefore independent of the previous MELD score but now more specific and superior to the original model for patients awaiting transplant. Serum sodium is often used as a marker for the severity of a disease, especially in cirrhosis where hyponatremia indicates solute-free water retention and the indirect marker of portal hypertension during cirrhosis. The formula used is the one below and sodium normal values are around 135 mEq/L.

The sodium addition in the model was based on the registration data from the United Network for Organ Sharing.

This model evaluation is used in patients in which cirrhosis is caused by factors that are not reversible and transplant is the only solution.

This MELD-Na score calculator differs from the standard MELD calculator because it uses the Na value to adapt the result and to provide a more specialized view and improves upon the MELD Score for liver cirrhosis, especially in regard to the mortality prediction. This health tool assesses the outcome in patients who need transplant or suffer from a serious liver condition such as cirrhosis and adds the serum sodium determination to the precedent equation in the Model of End Stage Liver Disease. How does this MELD Na score calculator work?
