How to Use This Calculator
- Enter Serum Bilirubin in mg/dL, Serum Albumin in g/dL, and INR from current labs.
- Enter Ascites grade (none, mild, or moderate-severe) and Encephalopathy grade.
- Review the Total Child-Pugh Score and Class (A, B, or C).
- Check 1-Year and 2-Year Survival estimates to guide prognosis discussions.
- Use Perioperative Mortality percentage to assess surgical risk in cirrhotic patients.
How the result changes with Serum Albumin (g/dL)
| Serum Albumin (g/dL) | Child-Pugh Score | Class (1=A, 2=B, 3=C) |
|---|---|---|
| 0.69 | 7 | 2 |
| 2.17 | 7 | 2 |
| 3.94 | 5 | 1 |
| 5.41 | 5 | 1 |
What each input means
- Total Bilirubin (mg/dL)
- Serum total bilirubin. <2 = 1pt, 2–3 = 2pts, >3 = 3pts.
- Serum Albumin (g/dL)
- Serum albumin. >3.5 = 1pt, 2.8–3.5 = 2pts, <2.8 = 3pts.
- INR
- International Normalized Ratio. <1.7 = 1pt, 1.7–2.3 = 2pts, >2.3 = 3pts.
- Ascites
- Select ascites severity.
- Encephalopathy
- Select encephalopathy grade.
What each result means
- Child-Pugh Score
- Total score from 5 to 15.
- Class (1=A, 2=B, 3=C)
- A (5–6): well-compensated, B (7–9): significant impairment, C (10–15): decompensated.
- 1-Year Survival (%)
- Approximate 1-year survival: A ~100%, B ~81%, C ~45%.
- 2-Year Survival (%)
- Approximate 2-year survival: A ~85%, B ~57%, C ~35%.
- Perioperative Mortality (%)
- Approximate surgical mortality risk: A ~10%, B ~30%, C ~82%.
- Bilirubin Points
- Points assigned for bilirubin (1–3).
- Albumin Points
- Points assigned for albumin (1–3).
- INR Points
- Points assigned for INR (1–3).
- Ascites Points
- Points assigned for ascites (1–3).
- Encephalopathy Points
- Points assigned for encephalopathy (1–3).
