PURPOSE: To determine the use of D-dimers in the diagnostic approach to patients presenting to the emergency department (ED) with suspected venous thromboembolism (VTE).

METHODS: We performed a retrospective chart review of all adult patients presenting to the ED of the Jewish General Hospital (Montreal, Canada) between March 23rd and April 3rd, 2015 and had a high sensitivity D-dimer requested. Patients evaluated for non-VTE conditions were excluded. For all included patients, we determined if a Wells score prior to D-dimer requisition was recorded. For patients without a documented Wells score, we calculated the Modified Wells score based on data from the ED physician’s initial history and physical exam. We determined diagnostic imaging following D-dimer in all patients.
