Example
- Preoperative shock
- Yes
- Perforation present > 24 h
- Yes
Result: Boey score 2 of 3 — 2 operative risk factors.
The tool opens with these values already filled in. Replace them with your own.
What the result means
- 0-3
- Preoperative shock, perforation > 24 h, significant comorbidity, each 1 point. Operative mortality rises steeply with each factor. A risk score, not a diagnosis.
What you enter
- Preoperative shock (SBP < 100 mmHg)
- Perforation present > 24 h
- Significant medical comorbidity
