Child-Pugh Score Calculator

The Child-Pugh Score calculator can be used to quickly assess the severity of cirrhosis, life expectancy, and risk of perioperative abdominal surgery mortality in patients with liver disease. To use this tool, you will need bilirubin, albumin, prothrombin time (INR), ascites, and encephalopathy grade. Each of these measures have corresponding categories in the Child-Pugh Score calculator that give 1, 2, or 3 points. After inputting your values, the calculator will provide the severity of cirrhosis based on Child-Pugh class, life expectancy, and abdominal surgery perioperative mortality rate.

Child-Pugh Score Calculator Results

Based on bilirubin, albumin, prothrombin time (INR), ascites, and encephalopathy the Child-Pugh Score calculator puts patients into one of three risk classes:

• Class A (5 to 6 points): Life expectancy is 15-20 years. Perioperative mortality rate is 10%.
• Class B (7 to 9 points): Life expectancy is 4-14 years. Perioperative mortality rate is 30%.
• Class C (10 to 15 points): Life expectancy is 1-3 years. Perioperative mortality rate is 82%.

Clinical Applications of the Child-Pugh Score Calculator

The Child-Pugh Score is commonly used in practice to help guide care decisions related such as elective abdominal surgery or transjugular intrahepatic portosystemic shunt (TIPS).

Child-Pugh Class A patients are generally considered safe candidates for elective surgery.
Child-Pugh Class B patients are at higher risk, but can undergo surgery after medical optimization.
In Child-Pugh Class C patients, elective surgeries are not considered a safe option even after medical optimization.

In Interventional Oncology, Child-Pugh Score can also be useful in determining the appropriate treatment method for hepatocellular carcinoma (HCC). Placing the Child-Pugh Score into the patient’s clinical context, in addition to understanding the goals of treatment and extent of locoregional therapy, can help shape a patient’s individualized HCC treatment plan.

Limitations of the Child-Pugh Score Calculator

The Child-Pugh Score calculator, despite its ease of use, has important limitations. One limitation is that the risk model uses low-resolution cut-off values in scoring. There is no evidence that these cut-off values define significant changes in mortality, so a small change in value can disproportionately modify the mortality risk determined by the Child-Pugh Score. Another limitation is that some of the variables in the calculator are based on subjective factors. Specifically, subjective interpretation of ascites and encephalopathy may yield different assessments. A third limitation is that Child-Pugh does not consider other prognostic factors like renal function. These limitations are mostly accounted for in the MELD calculator, however the MELD score requires a different set of clinical inputs.
