About
The BISAP (Bedside Index for Severity in Acute Pancreatitis) score is a prognostic scoring system that predicts mortality in acute pancreatitis. It uses five simple parameters available within the first 24 hours of admission. BISAP is simpler than APACHE II and Ranson's criteria, requiring no complex physiological data, and can be calculated at the bedside using routine clinical information.
Formula
BISAP = B + I + S + A + P (0–5)
B = BUN >25, I = Impaired mental status, S = SIRS ≥2, A = Age >60, P = Pleural effusion
Interpretation
| BISAP Score | Mortality Risk |
|---|---|
| 0 | < 1% |
| 1 | < 2% |
| 2 | ~2% |
| 3 | 5–8% |
| 4 | 10–20% |
| 5 | > 25% |
