Association of Guideline Publication and Delays to Treatment in Pediatric Status Epilepticus

Objective: To determine whether publication of evidence on delays in time to treatment shortens time to treatment in pediatric refractory convulsive status epilepticus (rSE), we compared time to treatment before (2011-2014) and after (2015-2019) publication of evidence of delays in treatment of rSE in the Pediatric Status Epilepticus Research Group (pSERG) as assessed by patient interviews and record review.

Methods: We performed a retrospective analysis of a prospectively collected dataset from June 2011 to September 2019 on pediatric patients (1 month-21 years of age) with rSE.

Results: We studied 328 patients (56% male) with median (25th-75th percentile [p-p]) age of 3.8 (1.3-9.4) years. There were no differences in the median (p-p) time to first benzodiazepine (BZD) (20 [5-52.5] vs 15 [5-38] minutes, = 0.3919), time to first non-BZD antiseizure medication (68 [34.5-163.5] vs 65 [33-142] minutes, = 0.7328), and time to first continuous infusion (186 [124.2-571] vs 160 [89.5-495] minutes, = 0.2236). Among 157 patients with out-of-hospital onset whose time to hospital arrival was available, the proportion who received at least 1 BZD before hospital arrival increased after publication of evidence of delays (41 of 81 [50.6%] vs 57 of 76 [75%], = 0.0018), and the odds ratio (OR) was also increased in multivariable logistic regression (OR 4.35 [95% confidence interval 1.96-10.3], = 0.0005).

Conclusion: Publication of evidence on delays in time to treatment was not associated with improvements in time to treatment of rSE, although it was associated with an increase in the proportion of patients who received at least 1 BZD before hospital arrival.
