Surgical Risk Scale (Sutton)
Surgical Risk Scale (3–14): CEPOD operative urgency + ASA grade + BUPA operative-magnitude grade; a score of 8 or more is a common high-risk threshold.

Example
- CEPOD urgency
- 4
- ASA grade
- 4
- BUPA operative-magnitude grade
- 5
Result: Surgical Risk Scale 13 (CEPOD 4 + ASA 4 + BUPA 5): higher scores carry a higher in-hospital mortality; a score of 8 or more is a common high-risk threshold.
The tool opens with these values already filled in. Replace them with your own.
What the result means
- Use
- a fast risk-adjusted-audit score; higher carries a higher in-hospital mortality (Sutton β 0.84, P < 0.001), with ≥8 a common high-risk threshold.
What you enter
- CEPOD urgency (1–4)
- ASA grade (1–5)
- BUPA operative-magnitude grade (1–5)
How this is calculated
- Components
- CEPOD urgency (elective 1 to emergency 4) + ASA grade (1–5) + BUPA operative magnitude (minor 1 to complex-major 5) = 3–14.
