Is Video Head Impulse Testing a Safe, Reliable and Cost Effective Method of Assessment of Patients Presenting for Dizziness at a Comprehensive Stroke Center?
Is Video Head Impulse Testing a Safe, Reliable and Cost Effective Method of Assessment of Patients Presenting for Dizziness at a Comprehensive Stroke Center?
The purpose of this study is to evaluate the sensitivity and specificity of the video head impulse test (vHIT) device, when implemented in the acute ED setting to identify acute ischemic stroke or central pathology vs peripheral vestibular dysfunction in patient's presenting with vertigo. This study will evaluate the implementation of the device, consistency with current diagnostic standards, unnecessary administration of antithrombolytics and will further study the reduction in hospital admissions and overall healthcare costs.
In the proposed study, subjects admitted to the Emergency Department (ED) with symptoms of dizziness, concerning for an acute ischemic stroke, will undergo routine triage (bedside neurologic examination, head impulse testing, CT scan) and will then be tested with a vHIT device to attempt to further identify the cause of dizziness, after standard of care testing has been performed. The clinician performing the vHIT will be blinded to the result of the CT scan before entering their report.
