Complications during and after ICU stay are associated with increased mortality after status epilepticus
2024
Overview
Status Epilepticus (SE) is a neurological emergency with high mortality rate that often requires admission in Intensive Care Units (ICU). Several factors of worse outcome have been identified in prior studies. The aim of our study was to determine the mortality in ICU and in the ward in patients with SE admitted to an ICU and to identify risk factors of mortality.
Retrospective cohort study of patients admitted with SE treated in the ICU of a tertiary medical center between 2015 and 2020. The primary outcome measure was mortality in the ICU (ICU death) or in the ward after ICU discharge (post-ICU death).
252 patients were included, with a mean age of 63 (±16) years and 127 males (50 %). 58 died in the ICU, 27 died in the ward. Overall mortality was associated with a higher burden of comorbidities (OR:1.28, p < 0.001), the use of vasopressors (OR: 5.65, p < 0.001) and a higher burden of ICU complications (OR: 1.32, p = 0.002). Mortality rate was higher in more severe SE episodes (nonconvulsive, acute symptomatic and refractoriness.
In-ICU mortality was associated with the use of vasopressors (OR: 7.92, p<0.001) and mechanical ventilation (OR: 3.13, p = 0.031), the length of in-ICU stay (OR: 0.91, p = 0.005) and a higher burden of ICU complications (OR: 1.37, p = 0.001). Compared to post-ICU deaths, ICU deaths also had higher Sequential Organ Failure Assessment (SOFA) score on ICU admission (p<0.001).
Post-ICU mortality was associated with a higher burden of comorbidities (OR: 1.34, p<0.001), a higher burden of complications after ICU-discharge (OR: 1.33, p = 0.01), and more often refractory SE episode (OR: 2.63, p = 0.01). Compared to survivors, post-ICU deaths experienced mostly infectious and respiratory complications, after ICU-discharge.
Death was more frequent in more severe SE episodes: non convulsive semiology, acute etiology, and refractoriness. In-ICU, post-ICU and all-cause mortality in patients with SE admitted to an ICU are all associated with a higher burden of comorbidities, which are non-modifiable prognostic factors, but also with a higher burden of complications, some of which are preventable, such as respiratory infections.
•Status Epilepticus (SE) requiring ICU admission is high.•In-ICU mortality was associated with a more severe SE, a more severe medical condition and more complications during ICU stay.•Mortality after ICU discharge was associated with more comorbidities and complications after and during ICU stay.•Screening and prevention of complications could decrease mortality in SE.
