Decreasing Seizure Treatment Time Through Quality Improvement Reduces Critical Care Utilization

Abstract

BackgroundRapid, effective treatment for status epilepticus reduces associated morbidity and mortality, yet medication delivery remains slow in many hospitalized patients. We utilized quality improvement (QI) methodology to improve treatment times for hospitalized children with status epilepticus. We hypothesized rapid initial seizure treatment would decrease seizure morbidity. MethodsWe utilized QI and statistical process control analysis in a nonintensive care setting within a tertiary care pediatric hospital. We performed Plan-Do-Study-Act cycles including (1) revising the nursing process for responding to seizures, (2) emphasizing intranasal midazolam over intravenous lorazepam, (3) relocating medications and supplies, (4) developing documentation tools and reinforcing correct processes, (5) developing and disseminating an online education module for residents and nurse practitioners, and (6) completing standardization to intranasal midazolam. ResultsSeventeen months after starting the project, 66 seizures had been treated with a benzodiazepine in a median (p25-p75) time of 7.5 minutes (5 to 10), decreased from a baseline of 14 minutes (8-30) (P = 0.01). The proportion of patients receiving a benzodiazepine in 10 minutes or less improved from 39% to 79%. The proportion of patients transferred to intensive care decreased from a baseline of 39% to 9% (P < 0.005), resulting in an estimated $2.1 million in mitigated hospital charges. Significant harm did not occur during the implementation of these interventions. ConclusionsChildren with status epilepticus were treated with benzodiazepines more rapidly and effectively following implementation of QI methodology. These interventions reduced utilization of critical care and mitigated hospital charges.
