Aims: We ascertain less than 7-day mortality data in suspected pulmonary embolism (PE) in order to risk stratify patients suitable for outpatient imaging.

Methods: Retrospective identification of patients presenting to two emergency departments over a two-year period, with a radiologically confirmed PE. PESI and sPESI scores correlated with death at 1, 3, 7, 30 and 90 days.

Results: There was significant correlation between all PESI risk classes and death at 3, 7, 30 and 90 days (p<0.01), but not day 1. No deaths occurred within 1 and 3 days in low risk PESI groups or within 90 days in the low risk sPESI. Conclusion: PESI/sPESI could be reliably utilized to risk stratify patients being considered for outpatient investigation of PE.
