Study Summary

The Pediatric Dose Optimization for Seizures in Emergency Medical Services (PediDOSE) study is designed to improve how paramedics treat seizures in children on ambulances. Seizures are one of the most common reasons why people call an ambulance for a child, and paramedics typically administer midazolam to stop the seizure. One-third of children with active seizures on ambulances arrive at emergency departments still seizing. Prior research suggests that seizures on ambulances continue due to under-dosing and delayed delivery of medication. Under-dosing happens when calculation errors occur, and delayed medication delivery occurs due to the time required for dose calculation and placement of an intravenous line to give the medication. Seizures stop quickly when standardized medication doses are given as a muscular injection or a nasal spray. This research has primarily been done in adults, and evidence is needed to determine if this is effective and safe in children. PediDOSE optimizes how paramedics choose the midazolam dose by eliminating calculations and making the dose age-based. This study involves changing the seizure treatment protocols for ambulance services in 20 different cities, in a staggered and randomly-assigned manner. One aim of PediDOSE is to determine if using age to select one of four standardized doses of midazolam and giving it as a muscular injection or nasal spray is more effective than the current calculation-based method, as measured by the number of children arriving at emergency departments still seizing. The investigators believe that a standardized seizure protocol with age-based doses is more effective than current practice. Another aim of PediDOSE is to determine if a standardized seizure protocol with age-based doses is just as safe as current practice, since either ongoing seizures or receiving too much midazolam can interfere with breathing. The investigators believe that a standardized seizure protocol with age-based doses is jus

Primary Outcome

Binary assessment of whether the participant is seizing or not upon arrival to the emergency department, as measured by either a rapid response electroencephalogram (preferred) or clinical judgement (alternative).
