🫃 BISAP Score (Pancreatitis Severity)
Predict mortality in acute pancreatitis within 24 hours using the BISAP score.
BISAP Score (Pancreatitis Severity)
BUN > 25 mg/dL
Impaired mental status (GCS < 15)
SIRS (≥ 2 criteria)
Age > 60
Pleural effusion
When to use
Early severity assessment in acute pancreatitis.
How it works
1 point each: BUN > 25 mg/dL, impaired mental status, SIRS, age > 60, pleural effusion. ≥ 3 = high risk.
Key points
- Calculable within the first 24 h (unlike Ranson).
- ≥ 3 marks higher mortality and organ failure risk.
- Combine with revised Atlanta criteria and imaging.
