🫀 Child-Pugh Score (Cirrhosis)
Calculate the Child-Pugh score and class (A/B/C) to grade severity of chronic liver disease.
Clinical takeaway
Class A ~100%, B ~80%, C ~45% one-year survival (approximate).

When to use
Prognosis and peri-operative risk assessment in cirrhosis.
How it works
1–3 points each for bilirubin, albumin, INR, ascites and encephalopathy. Class A 5–6, B 7–9, C 10–15.
Key points
- Class A ~100%, B ~80%, C ~45% one-year survival (approximate).
- MELD-Na is preferred for transplant allocation.
- Higher class predicts greater surgical risk.

Worked calculation
The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.
| Bilirubin | < 2 mg/dL (< 34 µmol/L) |
|---|---|
| Albumin | > 3.5 g/dL |
| INR | < 1.7 |
| Ascites | None |
| Encephalopathy | None |

- Inputs: Bilirubin < 2 mg/dL (< 34 µmol/L), Albumin > 3.5 g/dL, INR < 1.7, Ascites None, Encephalopathy None → Result: Child-Pugh Class A (5 pts)（Total: 5 points, Prognosis (approx.): 1-year survival ~100%） Inputs: Bilirubin > 3 mg/dL (> 50), Albumin < 2.8 g/dL, INR > 2.3, Ascites Moderate–severe, Encephalopathy Grade 3–4 → Result: Child-Pugh Class C (15 pts)（Total: 15 points, Prognosis (approx.): 1-year survival ~45%）
