Abstract

Background and objectives: Resource use for managing simple febrile seizures decreased after the publication of guidelines. Less is known about resource use for complex febrile seizures (CFS), for which no guidelines exist. The objective of this study was to evaluate trends in management of CFS.

Methods: Using the Pediatric Health Information System (PHIS) Database, we retrospectively reviewed encounters of children 6 months to 6 years old presenting to the emergency department for a first encounter for CFS between January 1, 2009 and December 31, 2021. Data were compared between 3 distinct periods as follows: (1) before release of the simple febrile seizures guidelines-January 1, 2009 to January 31, 2011, and 2 subsequent 5-year time periods postguideline release; (2) February 1, 2011 to January 31, 2016; and (3) February 1, 2016 to December 31, 2021. The primary outcome was use of medical resources. Demographic and outcomes data were collected, including ultimate diagnosis with serious condition, including central nervous system infection, trauma, intracranial mass, or stroke.

Results: A total of 17,865 encounters from 36 children's hospitals were included for analysis. The mean age of participants was 1.89 years, 0.3% were coded as having status epilepticus, and 4.7% were admitted to the pediatric intensive care unit. The percentages of children admitted and receiving neuroimaging, labs, lumbar puncture, or EEG decreased over time, while drug screens and HSV testing increased. Fewer children received antiseizure medications, antibiotics, or acyclovir across the time periods. Median length of stay decreased in period 3 relative to period 1 (1.33 vs. 1.55 days). New serious diagnosis after presentation remained low at 0.2%. There was significant variation in resource use across hospitals.

Conclusion: Resource use for CFS decreased across most domains since 2009 without an increase in serious medical diagnoses. These findings highlight a potential opportunity to standardize resource use when managing CFS.
