suicide risk 30 days after a potentially traumatic event in patients treated by a medico-psychological emergency unit

Conditions: Suicide Risk

Summary: the national french survey "mental health in general population", showed that the risk of suicide was significantly increased during exposure to a potentially traumatic event (pte), with an increasing gradient depending on the psychological impact. this included not only people suffering from post-traumatic stress disorder but also those confronted with pte, presenting or having presented phenomena of reviviscence or at least an element of psychopathological impact. this risk could concern 30.2% of the population over the entire lifetime. internationally, recent reviews of the literature tend to show that victims of interpersonal violence are more at risk of suicide (or 1.99 95% ci: 1.73-2.28). nevertheless, the literature remains heterogeneous, the definitions vague and the temporal proximity of the violence little taken into account. it is therefore a large-scale phenomenon that remains little explored. to increase our knowledge in this area, the investigators will focus on patients treated by emergency medical psychological cells (cump), that is victims of disasters, accidents involving a large number of victims or events that may have significant psychological repercussions due to the circumstances surrounding them.
