EURopean Study on Encephalitis in Intensive CAre

Study Overview
=================
Brief Summary
-----------------
Prospective observational multicenter study in European ICUs. All patients admitted to the ICU for probable or confirmed Acute encephalitis (2013 IDSA - Infectious Disease Society of America criteria) will be included. Factors associated with a poor prognosis will be identified by multivariate analysis using a logistic regression.

Detailed Description
-----------------
Primary objective : evaluate the correlation between mRs score and the baseline characteristics Functional outcomes will be evaluated using the modified Rankin score (mRS) score, which is one of the most frequently used scores in acute neurological diseases [18]. A poor outcome will be defined by a mRS score > 2 (functional dependence or death). The investigator usually evaluates this score if the patient is still in the hospital 90 days after admission. Patients discharged from hospital within 90 days following ICU admission without major disability (mRS 0, 1 or 2) are considered to have a good outcome. Patients discharged within 90 days with a disability will be classified for the study according to the latest available data. Patients will not be contacted directly by the investigator for the study purposes. Secondary objectives : To identify additional prognosis factors : the clinical, radiological, biological and neurophysiological factors associated with poor outcome for patients admitted to the ICU with AE Day 28 mortality, in-ICU mortality, in-hospital mortality Major systemic complications (septic shock, hyponatremia, nosocomial pneumonia, catheter-related BSI, overt gastroenteral bleeding, pulmonary embolism) Major intracranial complications during ICU stay Status epilepticus Brain death Empyema/cerebral abscess Cerebral ischemia Intracranial bleeding ICP monitoring Neurosurgery The cause of death will be categorized into 2 categories: Systemic causes (cardiovascular failure, MOF) Neurological cause (Diffuse neurologic injury or withdrawal of care)

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Modified Rankin scale score | The modified Rankin Scale (mRS) is a commonly used scale for measuring the degree of disability or dependence in the daily activities of people who have suffered a stroke or other causes of neurological disability. It has become the most widely used clinical outcome measure for stroke clinical trials. | Day 90 | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Mortality at Day 28 | Rate of death at day 28 | Day 28 | 
| Systematic complications | Septic shock, hyponatremia | Day 90 |
