Abstract
PURPOSE: Estimate the cost of status epilepticus (SE) admissions in the USA using claim databases based on ICD-10 codes. METHOD: Descriptive retrospective study using national estimates for the year 2016 from the KID's Inpatient Database (KID) for pediatric patients and from the National Inpatient Sample (NIS) for adults. These databases are comprehensive collections of all-payer, encounter-level hospital care data in the United States of America. RESULTS: From a population of 6,106,405 pediatric admissions there were 580 admissions related to SE. From a population of 29,274,158 adult admissions there were 1,405 admissions related to SE. The median (p25-p75) cost of pediatric admissions related to SE was $8,749 ($4,875-$19,067) in 2016 USA dollars [$9,295 ($5,180-$20,258) in inflation-adjusted 2019 USA dollars], and for adult admissions related to SE it was $14,678 ($7,203-$28,388) in 2016 USA dollars [$15,595 ($7,653-$30,161) in inflation-adjusted 2019 USA dollars]. Transforming to 2019 USA dollars, the values from the current study are consistent with prior estimates in the literature from the KID and NIS databases with a progressive increase, except for the cost of super-refractory SE in children that has increased disproportionately. CONCLUSIONS: This study estimates that the cost of admissions related to SE in the USA is approximately $9,000 in children and $15,000 in adults and shows that the cost estimates have not markedly changed with the advent of ICD-10.
