MELD score predicts mortality in liver disease and prioritizes transplant allocation. It uses three objective lab values.

Formule

Apply formula: MELD = (0.957 × ln(creatinine) + 0.378 × ln(bilirubin) + 1.120 × ln(INR) - 0.643)
INR
INR value — Variable used in the calculation

Stapsgewijze handleiding

  1. 1Calculate from: creatinine, bilirubin, and INR
  2. 2Apply formula: MELD = (0.957 × ln(creatinine) + 0.378 × ln(bilirubin) + 1.120 × ln(INR) - 0.643)
  3. 3Score 0-40; higher indicates greater mortality risk

Uitgewerkte voorbeelden

Invoer
Creatinine 2.0, bilirubin 3.0, INR 2.5
Resultaat
MELD ≈ 26
Significant mortality risk

Veelgemaakte fouten om te vermijden

  • Using Child-Pugh instead of objective lab values
  • Not updating scores regularly as labs change

Veelgestelde vragen

Why use natural logarithms?

Log transformation compresses wide value ranges into predictive model; handles extreme values better.

What MELD score requires transplant?

MELD >15 may warrant consideration; MELD >30 carries urgent need. Scores change frequently requiring recalculation.
