PESI / sPESI
Prognosis after confirmation of pulmonary embolism.
PESI — pulmonary embolism
Principle
Age in years + contributions of the other ten variables; classes I≤65, II66–85, III86–105, IV106–125, V≥126.
Scope
Adult with confirmed acute pulmonary embolism; prognostic score, distinct from Wells, Geneva and PERC. No diagnosis inferred from another score. Age 18–120 years accepted in this technical pilot; missing data without imputation.
Interpretation limits
30-day prognosis after confirmed PE. A low result is insufficient to decide on discharge: stability, right ventricular function, comorbidities and feasibility of care still require assessment. No automatic prescription.
Formula and logic
Age in years + contributions of the other ten variables; classes I≤65, II66–85, III86–105, IV106–125, V≥126.
Interpretation
- 18–65
- Class I · Very low risk
- 66–85
- Class II · Low risk
- 86–105
- Class III · Intermediate risk
- 106–125
- Class IV · High risk
- 126–350
- Class V · Very high risk

sPESI — pulmonary embolism
Principle
One point per present variable; heart failure and chronic lung disease combined as one variable. Total 0–6.

- 0–0
- Low prognostic risk
- 1–6
- Increased prognostic risk
