Brief Summary

Status epilepticus (SE) is a common life-threatening neurological emergency in which prolonged or multiple closely spaced seizures can result in long-term impairments. SE remains associated with considerable mortality and morbidity, with little progress over the last three decades. The proportion of patients who die in the hospital is about 20% overall and 40% in patients with refractory SE. Morbidity is more difficult to evaluate, as adverse effects of SE are often difficult to differentiate from those attributed to the cause of SE. Our experience suggests that nearly 50% of patients may experience long-term functional impairments. The precise description of the consequences of these functional impairments and their impact on quality of life after SE requiring intensive care management has been little studied. Indeed, if cognitive, physical and mental impairments are now identified in the populations of patients who required intensive care under the term postresuscitation syndrome (PICS), neuronal lesions consecutive to the SE itselfor to its cause could be responsible for these different functional alterations. Thus, the following have been described: (i) cognitive disorders in the areas of attention, executive functions and verbal fluency, visual and working memory disorders, but also spatio-temporal disorders; (ii) physical disorders such as the so-called post-resuscitation polyneuromyopathy; and (iii) mental disorders such as anxiety disorders, depressive states or those related to post-traumatic stress. Assessment and characterization of patient-reported outcomes is essential to complement the holistic assessment of clinically relevant outcomes from the patient's perspective. The POSEIDON study was a cross-sectional collection of PROs and HR-QOL components, and associated with patient functional outcomes, in those who required ICU management for status epilepticus. We propose here to continue the description of potential alterations after a subsequent ME, namely a longitudinal study (POSEIDON 2) which will also include the evaluation of patient-reported experience (PREMS) and the measurement of family burden.

Outcome Measures

Primary Outcomes (1)

  • percentage of global impairment of HRQoL

    percentage of global impairment of HRQoL defined by one and/or other of the physical and mental impairments (after dichotomization of the SF 36 summary scores compared to the general population) in patients managed in the ICU for or with SE. 36-Item Short Form Survey (SF-36) (HRQoL)-Ranging score\[0-100\], a high score indicate better health status.

    at 3 month and 12 month

Secondary Outcomes (9)

  • percentage of cognitive impairment in patients managed in the ICU for or with SE

    at 3 month and 12 month

  • percentage of disability in patients managed in the ICU for or with SE

    at 3 month and 12 month

  • percentage of physical dependency in patients managed in the ICU for or with SE

    at 3 month and 12 month

  • percentage of anxiety and depression in patients managed in the ICU for or with SE

    at 3 month and 12 month

  • percentage of post traumatic syndrome disorder in patients managed in the ICU for or with SE

    at 3 month and 12 month

  • +4 more secondary outcomes
