Child-Pugh Score

The Child-Pugh score (or Child-Turcotte-Pugh score) is a well-established system used to assess the prognosis of chronic liver disease, primarily cirrhosis.

Evidence-based context for fast calculator use

Purpose:
Child-Pugh Score classifies cirrhosis severity into Class A, B, or C to estimate survival and guide liver transplant or hepatic surgery decisions.
Population:
patients undergoing liver-function, hepatocellular carcinoma staging, imaging, or transplant assessment
Factors:
Total Bilirubin, Albumin, INR, Ascites, Encephalopathy
Reference:
Pugh RN, Murray-Lyon IM, Dawson JL, Pietroni MC, Williams R. Transection of the oesophagus for bleeding oesophageal varices. Br J Surg. 1973;60(8):646-649.

Clinical Context & Background

The Child-Pugh score (or Child-Turcotte-Pugh score) is a well-established system used to assess the prognosis of chronic liver disease, primarily cirrhosis. It aggregates five clinical measures to stratify patients into risk classes (A, B, C). It is widely used to determine the necessity of liver transplantation and to assess perioperative mortality risk for non-hepatic surgery.

Formula Logic
Total Points = Bilirubin(1-3) + Albumin(1-3) + INR(1-3) + Ascites(1-3) + Encephalopathy(1-3)

When To Use

  • Use Child-Pugh Score when child-Pugh Score classifies cirrhosis severity into Class A, B, or C to estimate survival and guide liver transplant or hepatic surgery decisions.
  • Confirm that the patient, diagnosis, disease phase, and available inputs match the cited model before calculation.

How To Interpret

  • Interpret the displayed result using the calculator-specific formula and reference table, spanning Class A through Class C.
  • A boundary result should prompt input verification and clinical review rather than false precision.

What To Do Next

  • Integrate liver reserve, portal hypertension, tumor burden, vascular invasion, extrahepatic disease, performance status, and transplant policy.
  • Document the inputs, result, timing, and clinical context so the assessment can be reproduced.

Limitations

  • Liver function, HCC stage, imaging category, and transplant criteria are complementary but not interchangeable.
  • The result supports clinician judgment and does not independently determine treatment.

How to apply this result

For a representative case, verify Total Bilirubin, Albumin, INR, calculate the result, and confirm that its classification matches the highlighted reference band before continuing the disease-specific pathway.

Frequently Asked Questions

When should Child-Pugh Score be used?

Use it for patients undergoing liver-function, hepatocellular carcinoma staging, imaging, or transplant assessment when all required inputs and the intended clinical setting are confirmed.

Can Child-Pugh Score determine treatment by itself?

No. Interpret the result with the cited evidence, complete clinical assessment, current guidelines, and patient-specific goals.
