When to use
Stratify mortality risk to guide perioperative care.
How it works
Preoperative shock (SBP < 90), major medical illness, perforation > 24 h — each 1 point (0–3). Mortality ≈ 1.5/14.4/32.1/100%.
Key points
- Each factor sharply increases mortality.
- High scores warrant aggressive resuscitation and ICU care.
- Simple preoperative tool.

Worked calculation
The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.
| Preoperative shock (SBP < 90 mmHg) | No |
|---|---|
| Major medical illness (ASA III–V) | No |
| Perforation > 24 hours | No |
→Boey0/3
- Approx. mortality：1.5%
| Preoperative shock (SBP < 90 mmHg) | Yes (+1) |
|---|---|
| Major medical illness (ASA III–V) | Yes (+1) |
| Perforation > 24 hours | Yes (+1) |
→Boey3/3
- Approx. mortality：100%
- Note：High-risk — optimise resuscitation and consider intensive postoperative care.
