BackgroundThis retrospective study analyzed benzodiazepine usage patterns in relation to guideline recommendations for the treatment of generalized convulsive status epilepticus (GCSE) as practiced by emergency medical services (EMS) and the emergency department (ED) of an inner-city hospital. Secondary outcomes of interest were adverse events and admission/discharge outcomes.MethodsRecords of all patients≥18years old diagnosed with GCSE between June 2012 and September 2015 and transported by EMS to our hospital ED were reviewed.ResultsOf 44 patients analyzed, 43 (98%) had a history of epilepsy. Benzodiazepine utilization varied; EMS preferred midazolam (69% of cases) while the ED utilized lorazepam (91% of cases). Benzodiazepine dosages used were lower than guideline recommendations. Seizure activity was aborted with benzodiazepines alone in 22 (50%) patients. Twelve patients (27%) experienced seizure recurrence following SE treatment and achievement of seizure cessation. Twenty-three (52%) patients required intubation after arrival to ED. All 44 patients were admitted; 30 (68%) required admission to the intensive care unit.ConclusionsThere was consistent underdosing of benzodiazepines in treatment of GCSE in both EMS and ED settings likely resulting in underachievement of seizure cessation, while intubation rates were higher than reported when compared to previous studies. Prospective studies are needed to identify barriers to optimal benzodiazepine usage in GCSE patients.Copyright © 2017 Elsevier B.V. All rights reserved.
