Child-Pugh Score for Cirrhosis

Classify severity of liver cirrhosis and estimate prognosis

Calculated Child-Pugh Score
5/ 15
Class A: Good Prognosis (5-6)
Reviewed by the CareCalculus Clinical Team·MD, ICU & Emergency Medicine specialists·Updated 2026

Clinical Interpretation

Class A (5-6 points) represents mild disease. Class B (7-9 points) represents moderate disease. Class C (10-15 points) represents severe disease. High scores correlate with reduced 1-year and 2-year survival.

Mathematical Metric

Child-Pugh = Bilirubin + Albumin + INR + Ascites + Encephalopathy

Frequently Asked Questions

What is the Child-Pugh score?

The Child-Pugh score is a clinical staging system used to assess the prognosis of chronic liver disease, particularly cirrhosis. It evaluates total bilirubin, serum albumin, INR, ascites, and hepatic encephalopathy.

What are the Child-Pugh classification classes?

Patients are categorized into three classes: Class A (Score 5-6, 100% 1-year survival), Class B (Score 7-9, 81% 1-year survival), and Class C (Score 10-15, 45% 1-year survival).

How does the Child-Pugh score differ from the MELD score?

The Child-Pugh score includes subjective parameters (ascites and encephalopathy) alongside labs. The MELD score is purely objective and laboratory-based (creatinine, bilirubin, INR, sodium), making it preferred for transplant allocation.

What is the maximum Child-Pugh score?

The score ranges from a minimum of 5 points to a maximum of 15 points. Higher scores indicate more severe hepatic impairment and poorer prognosis.
