What the childs pugh calculator calculates
Scores the severity of cirrhosis from bilirubin, albumin, INR, ascites and hepatic encephalopathy, gives the Child-Pugh class A, B or C with the conventionally reported survival figures, and supports the cholestatic bilirubin bands used in PBC and PSC.
How to use this childs pugh calculator
Enter Underlying disease, Total bilirubin, Bilirubin unit and Serum albumin. Child-Pugh score updates as you type, and “Use a worked example” loads checked figures you can adjust. Change one figure at a time to see what drives the result.
How the result is worked out
Open “How this is worked out” beside the result for the step-by-step calculation behind Child-Pugh score, Class and What the class means.
The method follows Pugh RNH, Murray-Lyon IM, Dawson JL, Pietroni MC, Williams R. Transection of the oesophagus for bleeding oesophageal varices, Child CG, Turcotte JG. Surgery and portal hypertension. In: The Liver and Portal Hypertension and European Association for the Study of the Liver - EASL Clinical Practice Guidelines for the management of patients with decompensated cirrhosis.
Bilirubin 2.5, albumin 3.1, INR 1.8, mild ascites, no encephalopathy example
With Underlying disease: standard, Total bilirubin: 2.5, Serum albumin: 3.1, INR: 1.8, the calculator returns Child-Pugh score: 9, Class: B, Reported one-year survival: 80. This example is checked against an independent source in the test suite.
What you can compare
Change one input at a time to see how it affects Child-Pugh score, Class and What the class means. The inputs you can vary are Underlying disease, Total bilirubin, Bilirubin unit, Serum albumin, Albumin unit and INR.
Understanding Child-Pugh score, Class and What the class means
A severity score, not a prognosis for an individual. Two of the five items are subjective clinical gradings, and the survival percentages come from historical cohorts that predate current treatment. Interpretation belongs to a hepatology team.
