Study Description

Brief summary:

Patients will be selected after studying clinical records.Patients who had general anesthesia due to an injury related to severe trauma within 6 to 12 months prior to inclusion will be included. Three self-survey will be completed by the patient: PDEQ, PCL-5 and a demographic questionnaire. According to the PDEQ and PCL-5 scores, an association between a peri-traumatic dissociation state and a post-traumatic stress disorder can be established.

  • Condition or Disease:Severe Trauma
    General Anaesthesia
  • Intervention/Treatment: Diagnostic Test: PDEQ, PCL-5 and demographic survey
  • Phase: N/A

Detailed Description

Arms and interventions

Arm Intervention/treatment
Experimental: PDEQ, PCL-5 and demographic survey
State of the patient evaluated with questionnaires to make the connection between peri-traumatic dissociation and the occurrence of post-traumatic stress disorder
Diagnostic Test: PDEQ, PCL-5 and demographic survey

Outcome Measures

  • Primary Outcome Measures: 1. Studying association between the presence of peri-traumatic dissociation state and the achievement of post-traumatic stress disorder between 6 and 12 months in traumatized patients [ Time Frame: study baseline (6 to 12 months after initial hospitalisation) ]
    Association will be measured using PDEQ scale and PCL-5 scale. The peri-traumatic dissociation will be evaluated by the Peri-traumatique Dissociation Experience Questionnary (PDEQ scale). This questionnaire contains ten items to study the presence or not of a peri-traumatic dissociation state. The items are scored on a 5-point Likert scale ranging from 1 (not at all true) to 5 (extremely true). The total score is the sum of all the items. A score from 15 indicates a significant dissociation. The presence or not of a Post-Traumatic Stress Disorder (PTSD) will be evaluated by the Post-Traumatic Stress Disorder Checklist Scale-Version DSM 5 (PCL-5). This questionnaire contains twenty items to study the presence or not of a PTSD. A total score for symptom severity (0-80) can be obtained by summing the scores for each of the 20 items. A score over 31 indicates a PTSD.
  • Secondary Outcome Measures: 1. Measurement of the frequency of PTSD after severe trauma requiring general anesthesia. [ Time Frame: study baseline (6 to 12 months after initial hospitalisation) ]
  • 2. Research of Risk Factors Associated with the Occurrence of PTSD [ Time Frame: study baseline (6 to 12 months after initial hospitalisation) ]
