Similar antiseizure medication refill characteristics in Hispanic and White pediatric patients

Abstract

AimPrevious work has shown that children of Hispanic ethnicity have reduced likelihood to achieve seizure remission, but it was unknown why. The purpose of this study was to evaluate antiseizure medicine (ASM) refill characteristics, comparing Hispanic and non-Hispanic White pediatric patients. MethodsThis was a retrospective population-based study in children between ages 6 months and 15 years. Epilepsy outcome was categorized as seizure free, treatment failure, or undetermined. ASM refill characteristics were determined from an insurance provider. Results247 patients were identified: 52 (21 %) were treatment failure; 181 (73 %) were seizure free; and 14 (5.7 %) were undetermined. ASM refill rates were similar in Hispanic and White patients (38.2, 32.1, respectively). Hispanic and White patients had similar numbers of different ASMs prescribed (2.1 and 2.4). There was not a significant difference in proportion of days covered between Hispanic and White patients (0.99 and 0.95). InterpretationWe found no differences between pediatric Hispanic and White epilepsy patients, for number of ASM refills, the number of ASMs prescribed, the choice of ASMs, the proportion of days covered, or the lateness of refills. Our findings suggest that the observation of reduced likelihood to achieve seizure remission in pediatric Hispanic patients is not associated with ASM refill patterns.
