AVERT is a randomized controlled trial comparing video-oculography (VOG)-guided care to standard care to assess accuracy of diagnoses and initial management decisions for emergency department (ED) patients with a chief symptom of vertigo or dizziness suspected to be of vestibular cause. The trial will test the hypothesis that VOG-guided rapid triage (VRT) will accurately, safely, and efficiently differentiate peripheral from central vestibular disorders in ED patients presenting acute vertigo or dizziness, and that doing so has the potential to improve post-treatment clinical outcomes for these patients.
