PESI estimates a PE patient's short-term mortality risk using clinical variables, helping decide whether someone can be safely treated as an outpatient or needs hospital admission. This tool scores the simplified version (sPESI).
A simplified PESI of 0 identifies a low-risk patient who may be a candidate for outpatient anticoagulation. Any positive criterion (≥ 1) places the patient in the higher-risk group, generally warranting admission. The full PESI further stratifies risk into five classes using age and additional variables.
Yes — this is one of its main clinical uses: identifying patients low-risk enough to be treated with anticoagulation as an outpatient rather than admitted.
Full PESI uses age plus points for many variables to sort patients into five risk classes. The simplified sPESI condenses this to six yes/no criteria and a low-risk (0) versus high-risk (≥1) split.
All six criteria absent — low 30-day mortality risk, supporting consideration of outpatient anticoagulation in the right clinical setting.
No — it supports the decision. Social factors, bleeding risk, and follow-up availability also determine whether outpatient treatment is safe.
