What is Child-Pugh Score?
The Child-Pugh classification (also called Child-Turcotte-Pugh) is a prognostic scoring system that quantifies the severity of chronic liver disease and predicts survival in cirrhosis. Originally proposed by Child and Turcotte in 1964 and modified by Pugh et al. in 1973 to assess operative risk for portacaval shunts, it combines five parameters — total bilirubin, serum albumin, INR (prothrombin time), ascites, and hepatic encephalopathy — each scored 1 to 3 points. The total (5–15) defines three classes: A (5–6, well-compensated, ~100% 1-year survival), B (7–9, significant compromise, ~80%), and C (10–15, decompensated, ~45%).
How to use
- Select the bracket for bilirubin, albumin, INR, ascites, and encephalopathy.
- The total score (5–15) and Child-Pugh class with survival estimates update instantly.
- Use for prognosis and to assess perioperative risk in cirrhotic patients.
Frequently asked questions
What is the Child-Pugh score?
A 5–15 point score that grades the severity of chronic liver disease (cirrhosis) from bilirubin, albumin, INR, ascites, and encephalopathy, mapped to Class A, B, or C.
How are Child-Pugh classes defined?
Class A = 5–6 points, Class B = 7–9, Class C = 10–15. Higher class means worse hepatic reserve and prognosis.
Child-Pugh vs MELD?
MELD is objective (labs only) and used for transplant allocation; Child-Pugh adds clinical assessment of ascites and encephalopathy and is widely used for surgical risk and prognosis.
Why does Child-Pugh class matter before surgery?
Operative mortality rises steeply with class — non-transplant surgery in Class C cirrhosis carries very high perioperative risk.
