Health care utilization of Hispanic/Latino veterans with epilepsy: A national population-based study

Hispanic/Latino people with epilepsy are a growing population that has been understudied in clinical epilepsy research. U.S. veterans are at a higher risk of epilepsy due to greater exposures including traumatic brain injury. Hispanic/Latino Veterans with Epilepsy (HL-VWEs) represent a growing population; however the treatment utilization patterns of this population have been vastly understudied.

HL-VWE were identified from administrative databases during fiscal year 2019. Variables compared between Hispanic and non-Hispanic VWEs included demographics, rurality, service era, utilization of clinical services/investigations, and service-connected injury. Chi-square and Student's t tests were used for comparisons.

Among 56 556 VWEs, 3247 (5.7%) were HL. HL-VWEs were younger (59.2 vs 63.2 years; p < .01) and more commonly urban-dwelling (81.6% vs 63.2%, p < .01) compared to non-HL-VWEs. They were also more likely to have served in recent missions such as the Persian Gulf War and post- 9/11 wars (p < .01). HL-VWEs had a higher utilization of all neurology services examined including neurology clinic visits, computed tomography (CT) scans, magnetic resonance imaging (MRI) scans, electroencephalography (EEG), epilepsy monitoring, and comprehensive epilepsy care (p < .01 for all). HL-VWEs were more likely to visit an emergency room or have seizure-related hospitalizations (p < .01). HL-VWEs were more likely to have a service-connected disability greater or equal to 50% (p < .01).

This study is one of the largest cohorts examining HL-VWEs. We found higher utilization of services in neurology, epilepsy, and neuroimaging by HL-VWEs. HL-VWE are younger, more commonly urban-dwelling, and more likely to have served during recent combat periods and have higher amounts of service-connected disability. Given that the proportion of Hispanic veterans is projected to rise over time, more research is needed to provide the best interventions and mitigate the long-term impact of epilepsy on this diverse patient group.
