Predictability of the Clinical Global Impression Scale (CGI) in Post Immediate in Psychotraumatic Impact

A functional unit of Urgent Medical Aid Service (SAMU), Medical-psychological emergency cell (CUMP) is an emergency medical device and provides immediate and post-immediate medico-psychological care for mentally injured people in psychotraumatic situations. CUMP also ensures immediate post follow-up of these patients, as well as departmental organization of psychotrauma consultation.

During the course of the treatment, victims are oriented, with a telephone callback which can be decided, allowing a remote reassessment of any psychotraumatic sequelae of the event. This phone reminder is part of routine practice following a CUMP intervention. The objective is then early detection of sequelae allowing rapid orientation on specific care pathways, in particular on the consultation of psychotrauma.

Post-traumatic stress disorder is a syndromic entity reactive to experience of a traumatogenic event (defined by the brutal, sudden and unexpected confrontation with death, or the loss of physical or psychological integrity), bringing together intrusive symptoms of reliving, behavioral avoidance of stimuli related to the traumatic event, persistent negative alterations in cognitions and mood, and neurovegetative hyperactivity, causing clinically significant distress and impaired the usual functioning of the subject.

Experiencing a psychotraumatic event in one's life is a frequent experience. Epidemiological data show a lifetime prevalence of around 30%. During and/or in the hours following a psychotraumatic event, people experience psychological, physiological and emotional upheavals called peritraumatic distress. Although most people recover on their own, a portion (8.3%) develop post-traumatic stress disorder.

However, one of the main characteristics of post-traumatic stress disorder is the presence of avoidance symptoms. Avoidance can take different forms such as non-confrontation with all the evocative clues of the traumatic event such as places, people and situations related to the traumatic event, but also the avoidance of thoughts, memories, conversations related to the traumatic event. This avoidance of thoughts and conversations can be a barrier to entry into trauma-focused psychotherapy. Indeed, talking about the traumatic event goes against this avoidance. A proactive approach at a distance from the event to re-evaluate the symptomatology of the people involved and thus propose an orientation towards specialized care in the field of psychotrauma in order to counter avoidance would seem entirely relevant.

Indeed, studies show the interest of a telephone follow-up by the Medical-Psychological Unit 15 days before an emergency repatriation of French people during the Lebanon war in 2016. On the one hand, remote telephone reminder of event is experienced positively by the people involved in the event and was able to highlight the presence of post-traumatic stress symptoms in 23% of cases. On the other hand, 56% of people were able to be referred to appropriate medio-psychological care following this telephone interview.

However, depending on the situation, all of the subjects involved in a psychotraumatic event cannot be reassessed, especially when event involves too many people. On the other hand, a significant proportion of subjects will not present psychotraumatic sequelae. Under these conditions, it seems appropriate to be able to define the proportion of psychotraumatized subjects most at risk of developing post-traumatic stress disorder (PTSD). Data from literature find that a high level of peritraumatic distress is largely associated with severity of post-traumatic stress symptoms .

Thus, peritraumatic distress reactions would be a good indicator of risk of developing a subsequent post-traumatic stress disorder. Several questionnaires exist to assess this peritraumatic distress. However, in a disaster situation and in view of the large number of victims potentially involved, it may be interesting to use a rapid and global assessment tool.

To do this, the severity item of the global clinical impression scale would respond to this clinical reality.

Research hypothesis

Hypothesis is that the severity item of the global clinical impression scale evaluated immediately after in a subject who has experienced a psychotraumatic event is a predictor of post-traumatic stress symptoms at 1 month and 6 months. Investigators expect a correlation between the scores of the PDI and the severity item of the global clinical impression while controlling the socio-demographic characteristics of the worker as well as his clinical experience. Patients included will have similar profiles and will be confronted with the same type of traumatic event.

Brief Protocol

* Inclusion visit : psychiatric assessment, socio-demographic data, questionnaire (CGI and Peritraumatic Distress Inventory scale(PDI)) * Follow-up visit: M1 and M6 : phone call (Post traumatic stress disorder Checklist Scale questionnaire (PCL 5), Mini International Neuropsychiatric Interview (MINI) : major depressive episod, alcohol consumption disorder, substance-related disorder (non-alcoholic).

Expected results

Investigators expect this work to confirm the prediction between the initial score on the CGI and the score at M1 and M6 on the PCL5. This result will make it possible to define an initial threshold for the CGI allowing the occurrence of a constituted post-traumatic stress disorder to be predicted, defined by a score greater than or equal to 33 on the PCL5. The objective is to set up a systematic recall protocol for subjects presenting with a state of acute stress for which an initial CGI score will be higher than the determined threshold, in order to be able, depending on the subsequent symptomatology, to offer early management. and focus of post traumatic stress disorder. This reminder protocol will be integrated into routine practices and deployed on the emergency reception service of Hospital.
