110 Pulmonary Embolism and Cancer – Can the PERC Rule Still Apply?

Abstract

Pulmonary Embolism (PE) in cancer is a controversial topic, with experts in several fields at odds regarding prophylactic anticoagulation, predictive models, and risk stratification. The Wells and Geneva Scores both include cancer as a high risk condition, though alone, cancer does not place an individual in the high risk category. The Pulmonary Embolism Rule-out Criteria (PERC score) is an accepted decision rule for use in the emergency department (ED) on low-risk patients. Our objective was to evaluate the performance of the PERC rule when applied retrospectively to a cohort of ED patients who were ultimately diagnosed with PE.
