PESI / sPESI (Pulmonary Embolism Severity Index)

Original PESI (Aujesky et al., 2005) with sPESI

Stratifies 30-day mortality risk in acute pulmonary embolism from 11 clinical variables (original PESI, classes I-V) and reports the simplified PESI alongside.

How this tool works

The Pulmonary Embolism Severity Index sums the patient's age in years with weighted points for male sex (10), cancer (30), heart failure (10), chronic lung disease (10), pulse >= 110/min (20), systolic blood pressure < 100 mmHg (30), respiratory rate >= 30/min (20), temperature < 36 C (20), altered mental status (60), and oxygen saturation < 90% (20). Classes I (<= 65) and II (66-85) are low risk, III (86-105) intermediate, and IV-V (106-125, > 125) high risk. The simplified PESI assigns one point each for age over 80, cancer, chronic cardiopulmonary disease, pulse >= 110, systolic pressure < 100, and saturation < 90%; zero points defines the low-risk group. Risk-factor fields left unanswered are treated as absent.
