OBJECTIVE: To examine the association between housing status and healthcare utilization in individuals presenting with seizure. METHODS: We performed a retrospective cross-sectional analysis of all adults (age >
18) presenting to a public hospital emergency department with seizures, defined by ICD-9/10 codes, between 1/1/2016 and 8/03/2019. They were categorized by housing status (people experiencing homelessness [PEH], people with housing). Healthcare utilization outcomes were 30-day re-visit to acute care, discharge disposition, and hospital length of stay for those admitted. We used multivariable linear and logistic regression models adjusting for age, comorbidities, and insurance status. RESULTS: There were 6483 individuals (2092 [32.3%] PEH). Compared to people with housing, PEH were younger (48.2 vs 50.9, CONCLUSION AND RELEVANCE: PEH with seizures had increased healthcare utilization. Further analysis, including imaging findings, anti-seizure medications prescribed, and presumed etiology, is needed to understand the drivers of healthcare utilization and identify appropriate interventions.
