Example
- Age
- 55 years
- Heart rate
- 130 bpm
- BUN
- 40 mg/dL
Result: SCORTEN 3 — predicted in-hospital mortality ≈ 35.3% (band 3).
The tool opens with these values already filled in. Replace them with your own.
What the result means
- Mortality
- 0–1 ≈ 3.2%, 2 ≈ 12.1%, 3 ≈ 35.3%, 4 ≈ 58.3%, ≥ 5 ≈ 90%. Best scored on day 1 and again on day 3.
What you enter
- Age
- Heart rate
- Body surface area detached
- BUN
- Serum bicarbonate
- Serum glucose
- Associated malignancy
How this is calculated
- Criteria
- seven, each 1 point: age ≥ 40, heart rate > 120, malignancy, BSA detached > 10%, BUN > 28 mg/dL, bicarbonate < 20 mEq/L, glucose > 252 mg/dL.
