Emergency Department Vestibular Rehabilitation Therapy for Dizziness and Vertigo

Completed

• Conditions: Dizziness; Vertigo

• Registration Number: NCT05122663
• Lead Sponsor: Northwestern University

Brief Summary

ED-VeRT will enroll up to 125 adult emergency department (ED) patients presenting with a chief complaint of dizziness or vertigo to collect longitudinal outcomes over 3 months of follow-up. This will include 50 patients who were evaluated by an ED physical therapist (ie, vestibular rehabilitation) during their ED visit and 50 patients who received usual care. The aims of this trial are to: (1) obtain initial estimates of participant recruitment and retention, intra-cluster correlation, and between-group outcome differences that will inform sample size calculation for a future randomized clinical trial, and (2) assess feasibility and fidelity of a clinical classification protocol for undifferentiated dizziness among patients receiving ED vestibular rehabilitation.

Primary Outcome Measures

Name	Time	Method
Dizziness Handicap Inventory (DHI)	Three months after the index ED visit.	The DHI contains 25 items quantifying self-perceived handicapping effects of dizziness symptoms.

Secondary Outcome Measures

Name	Time	Method
ED Length of Stay	Index ED visit (up to one week)	Total length of stay, inclusive of hospitalizations and observation stays.
Patient-Reported Medication Use in Last 24 Hours	Three months after the index ED visit.	Patient-reported medication use for dizziness will be collected using a standardized instrument assess whether participants have taken any dizziness medication in the last 24 hours (binary yes/no). The 24-hour timeframe was selected to maximize accuracy in patient recall. In brief, dizziness medications are listed by brand and generic names; a "yes" response to any medication triggers an additional query asking the participant to specify the medication dose (e.g., meclizine 25mg) and quantity (e.g., one pill).
Vestibular Activities Avoidance Instrument (VAAI-9)	Three months after the index ED visit.	The VAAI-9 identifies fear avoidance beliefs in persons with dizziness. The VAAI-9 is the 9-item short form version of the VAAI.
ED Diagnostic Imaging Utilization	Index ED visit (one day)	The proportion of ED visits in which any diagnostic imaging of the brain was performed, including computed tomography and magnetic resonance imaging.
