Child-Pugh Score
out of 15 possible points
Class Reference & Prognosis
Score 5–6 — Compensated Cirrhosis
1-year survival ~95–100% | 2-year survival ~90%
Well-tolerated disease; low surgical risk
Score 7–9 — Significant Compromise
1-year survival ~80% | 2-year survival ~60%
Moderate surgical risk; consider transplant evaluation
Score 10–15 — Decompensated Cirrhosis
1-year survival ~45% | 2-year survival ~35%
High surgical risk; urgent transplant evaluation warranted

Summary
The Child-Pugh score (also known as Child-Turcotte-Pugh or CTP score) is a widely used clinical scoring system to assess the severity of chronic liver disease, particularly cirrhosis. It evaluates five parameters — serum bilirubin, serum albumin, prothrombin time (PT/INR), degree of ascites, and grade of hepatic encephalopathy — each scored 1 to 3 points. The total score classifies patients into Class A (compensated cirrhosis, 5–6 points), Class B (significant functional compromise, 7–9 points), or Class C (decompensated cirrhosis, 10–15 points). The classification is used to estimate prognosis, guide treatment decisions, and determine candidacy for liver transplantation.
How it works
- Select the appropriate value for each of the 5 clinical parameters.
- Each parameter is scored 1 (best) to 3 (worst) based on measured values or clinical findings.
- The total score is calculated automatically as you make selections.
- Review the Child-Pugh Class (A, B, or C) and the associated 1-year and 2-year survival estimates.
- Use the results to support clinical decision-making alongside a qualified hepatologist.
Use cases
- Stratify cirrhosis severity for clinical decision-making.
- Estimate 1-year and 2-year survival in patients with chronic liver disease.
- Assess candidacy for liver transplantation or major surgery.
- Guide dosing adjustments for medications metabolized by the liver.
- Monitor disease progression over serial clinical assessments.
- Educate medical students and residents on hepatic function scoring.
