EVIDENCE-BASED ANSWERBedside ultrasound (US) by trained physicians reduces the time to deep venous thrombosis (DVT) diagnosis by 2 to 13 hours compared with US examinations performed in the radiology department, without sacrificing diagnostic accuracy. Protocols including bedside US may reduce unnecessary anticoagulation by 20% (while awaiting a radiology US), reduce the number of patients needing radiology US from 70% to 43%, and decrease use of d-dimer tests from 93% to 33% (SOR: B, cohort and cross-sectional studies).
