Summary

If deep vein thrombosis (DVT) is suspected among patients who have symptoms such as pain or swelling of the lower extremities, duplex ultrasound of the lower limb is the first-line imaging modality to diagnose DVT. However, duplex ultrasound is time consuming, requires patient transport to a diagnostic imaging facility. In recent years, abbereviated bedside ultrasound technique has been accepted by emergency physician to diagnose the presence of DVT. Several studies have proven that the accuracy of this abbreviated bedsude ultrasound for assessing the presence of deep vein thrombosis is not inferior to experts, but how much ultrasound experience is required to obtain the accuracy that does not inferior to experts has yet to be studied. The aim of this study is to identify how much learning by emergency physicians is needed to obtain the accuracy of the lower extremity ultrasound examination comparable to that of experts.

Detailed description

If deep vein thrombosis (DVT) is suspected among patients who have symptoms such as pain or swelling of the lower extremities, duplex ultrasound of the lower limb is the first-line imaging modality to diagnose DVT. However, duplex ultrasound is time consuming, requires patient transport to a diagnostic imaging facility, and the immediate availability of a trained radiologist or other vascular physician to provide a result since most physicians are unable to interpret such imaging. In recent years, abbereviated bedside ultrasound technique has been accepted by emergency physician to diagnose the presence of DVT. Compression is applied to assess the presence of thrombus and collapsibility only in three regions - iliofemoral junction, superficial femoral vein, popliteal vein. Several studies have proven that the accuracy of this abbreviated bedsude ultrasound for assessing the presence of deep vein thrombosis is not inferior to experts, but how much ultrasound experience is required to obtain the accuracy that does not inferior to experts has yet to be studied. The aim of this study is to identify how much learning by emergency physicians is needed to obtain the accuracy of the lower extremity ultrasound examination comparable to that of experts.
