Quality of Large-Scale Video Head Impulse Test Data: The Coronary Artery Risk Development in Young Adults (CARDIA) Study
Year: 2025
Type: article
Abstract: OBJECTIVE: To evaluate the quality and agreement of video head impulse test (vHIT) data collected by technicians without extensive vestibular training compared with audiologists. STUDY DESIGN: Review of data collected at a single time point (year 35) as part of a larger observational cohort study known as the Coronary Artery Risk Development in Young Adults (CARDIA) study. SETTING: Birmingham, AL; Chicago, IL; Minneapolis, MN; and Oakland, CA. PARTICIPANTS: 464 participants (928 ears) enrolled in the CARDIA Study, 5 novice technicians who completed vHIT, and 3 audiologists with extensive vHIT training. INTERVENTION: Each technician completed a 2-hour, virtual vHIT training. Technicians recorded average head velocity, gain, presence/absence of saccades, and a data quality rating. Three audiologists with extensive vestibular experience re-reviewed all data for comparison. Data categorized as noisy and/or having saccades were reanalyzed to determine whether data cleaning improved interpretation. MAIN OUTCOMES MEASURES: vHIT gain, quality of vHIT results, presence of saccades. RESULTS: A total of 823 ears (88.7%) were classified as normal, 10 ears (1.1%) were abnormal, 13 ears (1.4%) had low gain without saccades, and 82 ears (9%) had high gain (>1.2). The most frequent artifact was high gain. Data cleaning increased the percentage of saccades and changed the interpretation of eight participants (1.7%). CONCLUSIONS: Novice examiners can administer vHIT with online training and an initial practice period. Additional training on how to identify artifacts and clean data can improve population-based vHIT testing.
