How to Interpret
BISAP uses 5 bedside variables within the first 24 hours of admission to estimate the risk of severe acute pancreatitis and mortality.
| BISAP score | Approx. mortality | Risk |
|---|---|---|
| 0–1 | ~0.1–0.7% | Very low |
| 2 | ~2% | Low–moderate |
| 3 | ~5–8% | Moderate |
| 4 | ~13–19% | High |
| 5 | ~22–27% | Very high |
Even “low risk” scores can be serious in individual patients. Always interpret in the full clinical context and according to local guidelines.
