Bedside Ultrasound in the Assessment of Deep Venous Thrombosis: Effectiveness of In-Person Versus Online Instruction

NCT03573492 | Completed

• 1 other identifier: 17-017
• Study Type: interventional
• Target: 18
• Locations: 1 country
• Sites: 1

Brief Summary

This study will examine the effectiveness of pre-recorded instructional videos in the use of bedside ultrasonography to ascertain the presence of a lower extremity deep venous thrombosis (DVT) as compared to in-person lectures and hands-on training.

Conditions

Deep Vein Thrombosis; Pulmonary Embolism

Outcome Measures

Primary Outcomes (1)

• Superior education technique

  Whether pre-recorded instruction is capable of providing sufficient education to ED medical students to obtain accurate diagnosis of DVT via ultrasonography or if in-person education should continue to be considered the standard of training. This will be assessed by calculating the sensitivity and specificity of each education technique compared to the "gold standard" of the formal DVT ultrasound by radiology.
