Eye-Movement Desensitization and Reprocessing in the ED and Post-Traumatic Syndrome

Study Overview
=================
Brief Summary
-----------------
Millions people, all over the world, are admitted in the Emergency Department after a trauma or simply to receive medical cares. In France, it represents 10 million patients. Probably because of stress associated with the event, 20% will suffer a combination of non-specifics symptoms which persist for many months and with daily life quality impairment. The investigators hypothesize that an early intervention, such as Eye-Movement, Desensitization and Reprocessing (EMDR) could be performed in the ED and could prevent the occurrence of these symptoms

Detailed Description
-----------------
Emergency department are a privileged service for patients suffering from trauma and stressful medical conditions. In France every year 10 million people come or are taken to the emergency room (ER). Many studies have shown that 10-20% of these trauma patients develop a non-specific set of symptoms that can persist for several months after ED assessment. These includes, for example, headache, memory and/or concentration impairment, stress intolerance, irritability... These symptoms lead to an alteration in the quality of social, family and professional life, and therefore affect one to two millions people in France alone. The association between these symptoms and mild traumatic brain injury (MTBI) has already been demonstrated. It was defined as post-concussion syndrome (PCS) according to the DSM-IV-TR. However, several recent studies have shown that these symptoms are not specific to MTBI but may appear for any type of trauma and event for stressful medical conditions. PCS seems to appear for events occurring in a stressful environment or in people with psychological weaknesses. These symptoms will therefore be referred here to PCS-like syndrome (PCSLS). Moreover, PCS-LS symptoms appear to be very similar to those of the numbing and hyperarousal dimension of the Post Traumatic Stress Disorder (PTSD). A recent study, carried out by our team in the ED of Bordeaux University Hospital, showed that PCS-LS was associated with a high level of stress at ED discharge, whatever that stress level at entry. The Eye-Movement Desensitization and Reprocessing (EMDR) is a recognized psychotherapeutic approach in the treatment of PTSD and several single-session versions of the protocol have been proposed (R-TEP EMDR).The investigators hypothesize that the introduction of an early R-TEP EMDR intervention in emergencies can reduce the level of stress and thus the occurrence of the PCSLS and PTSD symptoms among a subset of patients screened for their high risk of PCS-LS. The study is a single-site open-label three-group randomized controlled trial designed to assess the feasibility of an early R-TEP EMDR intervention performed in the ED and to compare PCS-LS and PTSD symptoms at 3 months between the three randomization groups: (i) TEP-EMDR; (ii) 15' reassurance session; (iii) care as usual.

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| EMDR protocol completion | Eye-Movement Desensitization and Reprocessing, performed in a population with high risk of PTS at the Emergency Department thanks to questionnaires | 12 hours after ED admission | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Recovery rate | 3 months after ED admission | 3 months | 
| Post-concussion Syndrome | Post-Concussion Syndrome (PCS) was assessed using the various definitions of PCS (ICD-10, DSM IV and Rivermaid) were selected: headache, feelings of dizziness, nausea or vomiting, noise sensitivity, sleeping disorders, fatigue, irritability, feeling depressed, anxiety, intolerance to stress, feeling frustrated or impatient, forgetfulness or poor memory, poor concentration, taking longer to think, blurred vision, double vision, light sensitivity, restlessness, personality change. In line with PCS definition in the context of mild head injury, we defined patients with PCS as those who reported at least 3 of these symptoms. | 3 months after ED admission | 
| Post-Traumatic Stress Disorder | Post-Traumatic Stress Disorder was defined using the PTSD Check-List Scale. The presence of the 17 symptoms of the DSM-IV-R definition for PTSD were also assessed for the 3-month phone The diagnosis of PTSD requires that one or more symptoms from each of those categories be present for at least a month and that those symptoms interfere seriously with leading a normal life. | 3 months after ED admission | 
| Chronic Pain at 3 months | Self reported by phone | 3 months after ED admission |
