Racial and Ethnic Differences in Hospital Admission and Diagnostic Evaluation for Febrile Seizures in the Emergency Department.

OBJECTIVE: To examine differences in hospital admission and diagnostic evaluation for febrile seizure by race and ethnicity.

STUDY DESIGN: We conducted a cross-sectional study among children 6 months to 6 years with simple or complex febrile seizure between January 1, 2016, and December 31, 2021, utilizing data from the Pediatric Health Information System. The primary outcome was hospital admission. Secondary outcomes included the proportion of encounters with neuroimaging or lumbar puncture. We used mixed-effects logistic regression model with random intercept for hospital and patient to estimate the association between outcomes and race and ethnicity after adjusting for covariates, including seizure type.

RESULTS: In total, 94,884 encounters were included. Most encounters occurred among children of non-Hispanic White (37.0%), Black (23.9%), and Hispanic/Latino (24.6%) race and ethnicity. Black and Hispanic/Latino children had 29% (aOR 0.71; 95% CI: 0.66, 0.75) and 26% (aOR 0.74; 95% CI: 0.69, 0.80) lower odds of hospital admission compared with non-Hispanic White children, respectively. Black and Hispanic/Latino children had 21% (aOR 0.79; 95% CI: 0.73, 0.86) and 22% (aOR 0.78; 95% CI: 0.71, 0.85) lower adjusted odds of neuroimaging compared with non-Hispanic White children. For complex febrile seizure, the adjusted odds of lumbar puncture was significantly higher among Asian children (aOR 2.12; 95% CI: 1.19, 3.77) compared with non-Hispanic White children. There were no racial differences in the odds of lumbar puncture for simple febrile seizure.

CONCLUSIONS: Compared with non-Hispanic White children, Black and Hispanic/Latino children with febrile seizures are less likely to be hospitalized or receive neuroimaging.
