Worked out from Kamath PS, Wiesner RH, Malinchoc M, et al. A model to predict survival in patients with end-stage liver disease and 4 other sources.
MELD is validated in chronic liver disease from the age of 12; it is not a paediatric score and does not apply to acute liver failure.
A prognostic score used for organ allocation, not a diagnosis or a prognosis for an individual. The mortality figures are waiting-list mortality from a historical OPTN cohort. Interpretation and any transplant decision belong to a hepatology team.

How this is worked out

4 steps
  1. Bounded inputs: bilirubin 4.2, INR 1.6, creatinine 1.9, sodium 130, albumin 3.
  2. MELD(i) = 10 x [0.957 ln(1.9) + 0.378 ln(4.2) + 1.120 ln(1.6) + 0.643] = 23.3.
  3. MELD 3.0 = 1.33 (female) + 4.56 ln(4.2) + 0.82 x 7 - 0.24 x 7 x ln(4.2) + 9.09 ln(1.6) + 11.14 ln(1.9) + 1.85 x 0.5 - 1.83 x 0.5 x ln(1.9) + 6 = 28.9633.
  4. Rounded to the nearest whole number and held to the 6-40 range used for allocation: 29.
