Optimized Benzodiazepine Treatment of Pediatric Status Epilepticus Through a Standardized Emergency Medical Services Resuscitation Tool.

Background: Optimized benzodiazepine (BZD) dosing decreases morbidity and mortality in children with status epilepticus (SE), but previous studies have documented widespread underdosing. Prior interventions have focused on in-hospital SE treatment, although more than 75% of pediatric patients with SE are initially treated by emergency medical services (EMS). Our goal was to assess whether an EMS-focused, collaboratively developed dosing resuscitation aid (Medic One Pediatric [MOPed] cards) and training could improve BZD dosing and pediatric SE outcomes.

Methods: We conducted a retrospective review of patients aged 12 years and younger treated by EMS for SE and transferred to Seattle Children's Hospital during the 1 year before and immediately after MOPed card training. The primary outcome was the percentage of patients receiving underdosed BZD treatment. Secondary outcomes included time to second-line antiseizure medication (ASM), intubation, and intensive care unit (ICU) admission.

Results: The 44 children before and 33 after MOPed implementation were similar with respect to age, gender, and pre-existing epilepsy diagnosis. The percentage of children receiving underdosed BZDs fell from 52% to 6% after MOPed implementation (P < 0.001). There was no significant decrease in requirement for intubation and ICU admission. The interval to treatment with a second-line ASM remained prolonged.

Conclusions: EMS-focused training significantly increased the percentage of outpatient pediatric patients with SE who received recommended initial BZD treatment. This improvement in management of SE did not significantly alter the rate of intubation or ICU admission, suggesting the need for further optimization of out-of-hospital SE care, particularly access to and timely use of second-line ASMs.
