Frequently asked questions

What is the simplified PESI?

The simplified Pulmonary Embolism Severity Index (sPESI) is a 6-criteria score that predicts 30-day mortality after acute pulmonary embolism.

What sPESI score is low risk?

A score of 0 identifies low-risk PE (≈ 1% 30-day mortality), supporting consideration of early discharge or outpatient treatment in suitable patients.

sPESI vs full PESI?

The original PESI uses 11 weighted variables and stratifies into 5 classes; sPESI is dichotomous (0 vs ≥ 1) and easier to apply with comparable prognostic performance.

Is sPESI = 0 sufficient for home treatment?

It is necessary but not sufficient — also require hemodynamic stability, no RV dysfunction concerns, good social support, and absence of other reasons for admission.
