Child-Pugh Score (Cirrhosis Severity)

Calculate the Child-Pugh score to grade chronic liver disease / cirrhosis severity and estimate perioperative mortality. Five parameters scored 1–3 each (total 5–15): Total bilirubin (<2 mg/dL =1, 2–3 =2, >3 =3) — supports mg/dL or µmol/L input (auto ÷17.1); Serum albumin (>3.5 g/dL =1, 2.8–3.5 =2, <2.8 =3); INR (<1.7 =1, 1.7–2.3 =2, >2.3 =3); Ascites (absent =1, slight/controlled =2, moderate–severe =3); Hepatic encephalopathy (none =1, grade I–II =2, grade III–IV =3). Classes: A (5–6) well-compensated (1-y ~100%, 2-y ~85%); B (7–9) significant compromise (1-y ~80%, 2-y ~60%); C (10–15) decompensated (1-y ~45%, 2-y ~35%). Derived from Pugh et al. 1973 (Br J Surg) and the original Child-Turcotte classification. Not medical advice.

Endpoint

HTTP

POST https://api.elysiatools.com/en/api/tools/child-pugh-score

Parameters

Name	Type	Required	Description
bilirubin	number	Yes	Total serum bilirubin. Select the unit. mg/dL thresholds: <2 (1), 2–3 (2), >3 (3); µmol/L is auto-converted (÷17.1).
bilirubinUnit	select	Yes	Unit of the entered bilirubin value. µmol/L is converted to mg/dL (÷17.1) for scoring.
albumin	number	Yes	Serum albumin in g/dL. >3.5 (1), 2.8–3.5 (2), <2.8 (3).
inr	number	Yes	International normalized ratio (INR) or prothrombin time-derived. <1.7 (1), 1.7–2.3 (2), >2.3 (3).
