Example
- Age
- 70 years
- Planned surgery category
- Major gastrointestinal
- Cancer
- Yes
Result: POSPOM 30 points: predicted in-hospital mortality 7.403%.
The tool opens with these values already filled in. Replace them with your own.
What the result means
- Total
- age-band points + 15 comorbidity points + procedure-category points, mapped to the published predicted in-hospital mortality (Supplemental Digital Content 3).
- Performance
- derived from > 5.5 million procedures; c-statistic 0.944 derivation, 0.929 validation. A preoperative estimate, not a guarantee.
