Child-Pugh Score

Assesses severity of chronic liver disease and cirrhosis. Guides prognosis and surgical risk.

Used in: Liver Disease & Cirrhosis

How to use & interpret

The Child-Pugh score grades the severity of chronic liver disease (cirrhosis) using bilirubin, albumin, INR, ascites and hepatic encephalopathy, classifying patients as A (5–6), B (7–9) or C (10–15).

Class A is well-compensated; class C carries the worst prognosis. It is widely used to estimate peri-operative and procedural risk and to guide drug dosing/avoidance in liver impairment. Two of its components (ascites, encephalopathy) are subjective, which is why MELD is preferred for transplant allocation.

Score interpretation

Child-Pugh Class A 5–6

Score 5–6: Class A — Well-compensated cirrhosis. 1-year survival ~100%.

→ Regular surveillance (AFP + USS 6-monthly). Endoscopy screening for varices. Liver transplant assessment if appropriate.

Child-Pugh Class B 7–9

Score 7–9: Class B — Significant functional compromise. 1-year survival ~80%.

→ Hepatology specialist management. Consider liver transplant referral. Manage complications.

Child-Pugh Class C 10–15

Score 10–15: Class C — Decompensated cirrhosis. 1-year survival ~45%.

→ Urgent liver transplant assessment. Aggressive management of decompensation. Palliative care discussion.

Frequently asked questions

Child-Pugh or MELD?

Child-Pugh is convenient for bedside prognosis, surgical-risk discussion and drug dosing; MELD is objective and better for transplant prioritisation and short-term mortality. They are complementary.
