Recurrence and Mortality After a First Status Epilepticus: A Retrospective Nationwide Study From the French National...

Area of Science:

• Neurology
• Public Health

Background:

• Status epilepticus (SE) has high short-term mortality, but long-term outcomes are less understood.
• Limited data exists on SE recurrence and long-term mortality rates.

Purpose of the Study:

• To determine 3-year recurrence and mortality rates after a first SE event.
• To identify risk factors associated with SE recurrence and mortality.

Main Methods:

• Retrospective cohort study using French National Health Data System (2011-2016).
• Included adult and infant patients surviving their first SE hospitalization.
• Follow-up for 3 years, analyzing recurrence, mortality, and causes of death using Cox models.

Main Results:

• The 3-year SE recurrence rate was 16.7%, and mortality rate was 25%.
• Factors associated with recurrence included younger age, prior epilepsy, alcohol use, and comorbidities.
• Male sex and older age were associated with mortality, while progressive causes and comorbidities were linked to both.

Conclusions:

• A significant risk of SE recurrence and death exists within 3 years post-event.
• Identified risk factors, many nonmodifiable, can aid in planning patient follow-up.
• Further understanding of these factors is crucial for optimizing post-SE care.
