Therapy delay in status epilepticus extends its duration and worsens its prognosis



Timing in status epilepticus (SE) attention is probably the most relevant modifiable prognostic factor and may influence SE duration and prognosis. We aimed to describe the precise relationship between management timing, duration, and prognosis of SE.


Observational longitudinal prospective study on a cohort of all patients diagnosed with SE admitted to our tertiary hospital from September 2017 to August 2019, with a 3‐month follow‐up. Univariate and multivariable analyses were performed to identify clinical and timing variables associated with SE duration and prognosis.


Eighty‐three SE affecting 76 patients were included. Median age was 73 years, 61.4% were women, median baseline modified Rankin Scale (mRS) was 2, and 55.4% had prior epilepsy. In the out‐of‐hospital group (n = 50), median time to emergencies was 1.3 h and to hospital admission 2.8 h. In the global series, median time to neurologist was 4.3 h, and median time to therapy initiation was 4.5 h. These four times positively correlated with SE duration (all Spearman’s rho coefficient >0.5, all p < .001). SE median duration was 24 h and was extended 1.2 h for each hour of treatment delay. A longer SE duration was associated with increased mortality and morbidity, both at hospital discharge and at 3‐month follow‐up (both p < .05). After 3 months, mortality was 30.1%, while recovery to baseline mRS occurred in 39.5%, with an overall median mRS of 4.


There were pervasive delays in all phases of SE attention, which conditioned a longer SE duration, and this led to increased long‐term morbimortality.
