โ UNOS
The Child-Pugh score (Child-Turcotte-Pugh) classifies cirrhosis severity using five clinical and laboratory parameters. Each parameter scores 1-3 points; total 5-15 maps to Class A (well-compensated), B (moderate), or C (decompensated). Class A has 100% 1-year survival; Class C has 45% 1-year survival. Used for prognosis, surgical risk, and transplant evaluation.

Key Takeaways
- โข Class A (5-6): Well-compensated; 100% 1-year survival; low surgical risk
- โข Class B (7-9): Moderate compromise; 80% 1-year survival; optimize before surgery
- โข Class C (10-15): Decompensated; 45% 1-year survival; urgent transplant evaluation
- โข MELD preferred for transplant allocation; Child-Pugh for prognosis and surgical risk
Did You Know?
How Does Child-Pugh Work?
Lab Parameters
Bilirubin (<2, 2-3, >3 mg/dL), albumin (>3.5, 2.8-3.5, <2.8 g/dL), INR (<1.7, 1.7-2.3, >2.3) each score 1-3.
Clinical Parameters
Ascites (none, mild, moderate-severe) and encephalopathy (West Haven Criteria) also score 1-3.
Classification
Sum all five scores. 5-6 = A, 7-9 = B, 10-15 = C. Higher class = worse prognosis.

Frequently Asked Questions
What is the Child-Pugh score?
A clinical tool that classifies cirrhosis severity using bilirubin, albumin, INR, ascites, and encephalopathy. Scores 5-15 map to Class A, B, or C.
What does Child-Pugh Class A mean?
Class A (5-6 points) indicates well-compensated cirrhosis with 100% 1-year and 85% 2-year survival. Lowest surgical risk.
When is Child-Pugh used vs MELD?
Child-Pugh is used for prognosis and surgical risk. MELD is preferred for liver transplant allocation in the US.
How is ascites scored?
None = 1 point, Mild/controlled = 2 points, Moderate-severe = 3 points. Based on clinical assessment.
What albumin unit should I use?
g/dL (US) or g/L (international). The calculator converts automatically. Normal albumin is >3.5 g/dL.
Can Child-Pugh predict transplant need?
Class C (10-15 points) suggests urgent transplant evaluation. MELD-Na is used for actual allocation.
