To assess the short-term outcome of status epilepticus (SE) and test the Epidemiology-based Mortality score in Status Epilepticus (EMSE) and the Status Epilepticus Severity Score (STESS) performance in outcome prediction.
Consecutive adults with SE in the Kuopio University Hospital emergency department were recruited between March 23 and December 31, 2015. The one-month outcome was assessed by a combined phone interview and medical record review using the Glasgow Outcome Scale-Extended. The prognostic performance of the EMSE-EAC (EMSE using the combination of etiology, age and comorbidity) and STESS were statistically evaluated.
We recorded 151 SE episodes in 137 patients, of whom 47 had a first-time epileptic event (seizure or SE). Of the SE episodes, 9.0% resulted in death, 31.6% in functional decline. For mortality prediction, the AUCs of the EMSE-EAC and STESS were 0.790 (95% CI: 0.633–0.947) and 0.736 (95% CI: 0.559–0.914), respectively. The optimal cutoff points were ≥ 34 for the EMSE-EAC and ≥ 4 for STESS. Negative predictive values for mortality using the EMSE-EAC-34 and STESS-4 were 97.5% and 96.7%, respectively. For functional decline prediction, the EMSE-EAC yielded statistically insignificant results, the STESS performance was poor (AUC = 0.621, 95% CI: 0.519–0.724).
Over 40% of SE patients suffer adverse outcomes. The EMSE-EAC and STESS are useful in short-term mortality prediction, with a high negative predictive value. The optimized cutoff points for the EMSE-EAC and STESS were ≥ 34 and ≥ 4 for cohort, respectively.
