What this Trial Is About

Each year, suicide is the cause of 8,580 deaths in France, it is the second leading cause of death among 15-24 year olds. People who have made a first suicide attempt are identified as being at greater risk of repeating a suicidal gesture, particularly in the first month following the gesture . At the same time, Brief Intervention Contact (BIC) is recognized as effective in reducing suicide deaths. A new brief intervention to prevent suicidal attempts has been developed in the United States by Santley \& Brown (2012) the results of its effectiveness are very encouraging. Investigators hypothesise that the implementation of a safety plan by the emergency department for suicidal patients included in the Vigilans system leads to a greater reduction in the reiteration of suicidality at 6 months compared to the usual management. Our main objective is to evaluate the effectiveness of the implementation of a safety plan by the emergency department nurse before discharge from the emergency department in reducing suicidal reiteration at six months after the suicide attempt, for suicidal patients included in the Vigilans programe, compared with the Vigilans programe alone. Our secondary objectives are * Reduce the reiteration of the suicidal act at 1 month * Encourage engagement in care at 1 month and 6 months * Reduce the use of emergency departments at 1 month and 6 months due to a suicidal crisis * Decrease suicide mortality at 6 months To study the implementation of the intervention: * To measure the quality of completion, and the duration of completion of the safety plan at 1 month, and 6 months. * Assess the acceptability of the safety plan by emergency department nurses, and then by the vigilantes. * Assess the acceptability of the safety plan by patient
