  Clinical Calculators - Child-Pugh Score  

The Child-Pugh Score is used to determine the prognosis of chronic liver disease, in particular cirrhosis. Originally, the Child-Pugh Score was used to predict mortality during surgery however it is now used to assess prognosis and the aggressiveness of treatment, including the value of a liver transplantation. The Child-Pugh Score is classified into Classes A to C, the latter predicting the worst prognosis.

You must give information about all five assessments - bilirubin, albumin, INR, ascites and hepatic encephalopathy - in order to determine the Child-Pugh Score for this patient.
