OBJECTIVE: To quantify the economic burden of all-cause health care resource utilization (HCRU) among adults with and without chronic vestibular impairment (CVI) after a mild traumatic brain injury (mTBI). DESIGN: Retrospective matched cohort study. SETTING: IQVIA Integrated Data Warehouse. PARTICIPANTS: People with mTBI+CVI (n = 20,441) matched on baseline age, sex, year of mTBI event, and Charlson Comorbidity Index (CCI) score to people with mTBI only (n = 20,441) (N = 40,882). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: All-cause health HCRU and costs at 12 and 24 months post mTBI diagnosis. RESULTS: People with mTBI+CVI had significantly higher all-cause HCRU and costs at both time points than those with mTBI only. Multivariable regression analysis showed that, when controlling for baseline variables, costs of care were 1.5 times higher for mTBI+CVI than mTBI only. CONCLUSIONS: People who developed CVI after mTBI had greater overall HCRU and costs for up to 2 years after the injury event compared with people who did not develop CVI after controlling for age, sex, region, and CCI score. Further research on access to follow-up services and effectiveness of interventions to address CVI is warranted.
