formula

MELD-Na = MELD Score - Na - 0.025 ×MELD ×(140-Na) + 140 Sodium is limited in a range of 125-140, and if outside of these bounds, is set to the nearest limit.

information

Interpretation:

The MELD-Na has been found to have a better fit for mortality prediction compared to the MELD Score alone.

pearls

usecase

reasons

The MELD-Na may improve upon theMELD Scorefor liver cirrhosis.

next_advice

Patients should be evaluated for transplant if no reversible causes of cirrhosis can be identified.

instructions

Note: The Organ Procurement and Transplantation Network recently incorporated sodium into their new MELD Score as of January 2016, using a different model than MELD-Na. We recommend using the new MELD Score primarily.
