⚕️ Clinical Disclaimer: The Child-Pugh score includes subjective components (ascites severity, encephalopathy grade) subject to inter-observer variability. It was not designed for transplant organ allocation (MELD is used for that purpose) but remains widely used for surgical risk stratification and prognosis in cirrhosis. Survival estimates are population averages and vary widely by etiology and management.

About the Child-Pugh Score

The Child-Pugh score (also called Child-Turcotte-Pugh or CTP) was originally developed by Child and Turcotte in 1964 and modified by Pugh in 1973 to assess the prognosis of patients with cirrhosis and guide surgical risk estimation, particularly for portosystemic shunt surgery. It classifies hepatic reserve into three categories — Class A (well-compensated), Class B (significant functional compromise), and Class C (decompensated).

Child-Pugh vs MELD

The MELD score replaced Child-Pugh for organ allocation due to its fully objective (laboratory-only) inputs and better prediction of short-term mortality. However, Child-Pugh remains clinically valuable for surgical risk assessment, hepatocellular carcinoma staging (Barcelona Clinic Liver Cancer criteria), and decisions about treatment tolerability (e.g., chemotherapy, procedures). Use both in clinical practice for complementary information.
