Why was sodium added to MELD?

Hyponatremia independently predicts 90-day mortality in cirrhosis. MELD-Na improves prediction of waitlist mortality vs standard MELD, particularly for patients with sodium below 130 mEq/L.

What MELD-Na score triggers transplant listing priority?

Scores above 15 typically meet criteria for listing. Scores above 25–30 indicate high waitlist mortality and urgency. Exception points may be granted for specific conditions.

How often is MELD-Na recalculated?

For listed patients: every 3 months for MELD-Na 10–18, every month for 19–24, every 2 weeks for 25+. Scores can be recalculated more frequently with clinical changes.

MELD-Na Sodium-Adjusted MELD Score Calculator

Calculate MELD-Na score incorporating serum sodium for liver transplant prioritization. MELD-Na = MELD + 1.32 × (137 − Na) − [0.033 × MELD × (137 − Na)]. Used by UNOS for organ allocation.
