MELD 3.0 (Kim 2021, OPTN 2023)

MELD 3.0 adds female sex and albumin to MELD-Na with updated coefficients and a creatinine cap of 3.0 mg/dL; it has been used for US liver allocation since July 2023. Range 6–40; higher scores mean higher 90-day waitlist mortality (score 20 ≈ 5% 90-day mortality).

  • Total bilirubin (mg/dL or µmol/L)
  • INR
  • Serum creatinine (mg/dL or µmol/L)
  • Serum sodium (mmol/L or mEq/L)
  • Serum albumin (g/dL or g/L)
  • Sex: Male; Female
  • Dialysis ≥2 times in the past week (or CVVHD ≥24 h) (yes/no)

≥ 30Very high; highest allocation priority

Formula

MELD 3.0 = 1.33 (if female) + 4.56 ln(bili) + 0.82 (137 − Na) − 0.24 (137 − Na) ln(bili) + 9.09 ln(INR) + 11.14 ln(Cr) + 1.85 (3.5 − Alb) − 1.83 (3.5 − Alb) ln(Cr) + 6; rounded. Bounds: labs <1 → 1; Cr max 3.0 (3.0 if dialysis ≥2×/wk or CVVHD); Na 125–137; albumin 1.5–3.5 g/dL; max 40.

Clinical pearls

  • Creatinine is capped at 3.0 mg/dL (not 4.0 as in MELD/MELD-Na), and dialysis sets creatinine to 3.0.
  • Women receive +1.33 to correct for creatinine underestimating renal dysfunction in smaller patients.
  • Albumin is bounded 1.5–3.5 g/dL, so albumin above 3.5 contributes nothing.

FAQ

What changed from MELD-Na to MELD 3.0?

MELD 3.0 adds female sex and serum albumin, adds bilirubin–sodium and albumin–creatinine interactions, refits the coefficients and lowers the creatinine cap to 3.0 mg/dL.

Is MELD 3.0 used for transplant allocation?

Yes. The OPTN adopted MELD 3.0 for adult liver allocation in the United States in July 2023.
