Summary
The Child-Turcotte-Pugh (CTP) score quantifies the severity of chronic liver disease and cirrhosis. It combines five parameters — total bilirubin, serum albumin, prothrombin time (INR), degree of ascites, and grade of hepatic encephalopathy — to produce a score between 5 and 15. Scores classify patients into class A (5–6, well-compensated), class B (7–9, significant compromise), or class C (10–15, decompensated). Class is used to estimate surgical risk, transplant eligibility, and prognosis.
How it works
- Each of five parameters — bilirubin, albumin, INR, ascites, and encephalopathy — is scored 1, 2, or 3 based on laboratory or clinical values.
- The five individual scores are summed to give a total between 5 and 15.
- The total maps to a class: A (5–6), B (7–9), or C (10–15), reflecting increasing severity.
- Class A predicts roughly 1–2% surgical mortality; class B 10–31%; class C 76–82%.
- The score is a clinical tool. Always interpret results alongside the full clinical picture.
Use cases
- Assessing a cirrhotic patient before elective surgery to estimate operative risk.
- Evaluating candidacy or urgency for liver transplantation.
- Monitoring disease progression over serial clinic visits.
- Communicating prognosis clearly between care teams.
- Classifying patients for clinical trial enrollment criteria.
