Child-Pugh Score - Evidencio

Evidencio uses JavaScript for many of its features. Please enable JavaScript to enable calculations

The Child-Pugh Score is intended to support clinical decision making by estimating the severity of liver disease in patients with liver dysfunction. The device combines Bilirubin, Albumin, Prothrombin time or INR, Encephalopathy grade and Ascites severity to estimate severity of liver dysfunction, by classifying it as Child-Pugh class A, B or C.

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.

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.

Conditional information

The outcome of the Child-Pugh Score can be used to stratify patients according to liver functioning and prognosis. However, the effectiveness of the Child-Pugh Score and the associated risk percentages can differ between different Cirrhosis aetiologies and patient conditions.

Additional information

The Child-Pugh was originally derived in a series of 38 patients seen between January 1966 and July 1972 admitted as an emergency with bleeding oesophageal varices, in which ligation of the oesophageal varices via the thransthoracic approach was performed after controlling the haemorrhage for 24 hours by other means.
