The Child-Pugh Score
The Child-Pugh score was originally developed in 1973. It was then developed to predict mortality during surgery, but is nowadays often used to determine prognosis in patients suffering from chronic liver disease (mostly cirrhosis).

The Child-Pugh score is also known as the Child-Turcotte-Pugh score or the Child score. 

Enter the patients' clinical characteristics below to calculate the Child-Pugh score. If the continuous values (i.e. bilirubin, albumin & INR) of the patients are higher or lower than the minimum/maximum allowed value to enter, please enter the maximum or the minimum of the slider. It does not influence the score any further.
