Evaluation of the Feasabilty and Acceptability of a Safety Plan After Suicidal Attempt to Prevent Recurrence After an Emergency Department Admission.

Suicide is one of the leading causes of death worldwide, with more than 700 000 deaths due to suicide every year, according to the World Health Organisation (WHO). In France, mortality rate by suicide is 17% higher than the European average; moreover, around 7% if the population (aged 18-75 years old) attempted suicide in their life.

Since years 2000, a series of preventative interventions have been developed to reduce suicide risk, with perhaps the most widely used is suicide safety planning, which is a brief intervention to help individuals who survived a suicide attempt to develop a set of tools and steps, to reduce the likelihood of engaging in suicidal behaviour. Several studies showed positive results after evaluating the efficacy of suicide safety planning for reducing patient risk. Recently, a systematic review concluded that Safety Planning is a valuable intervention for patients experiencing suicide-related distress, and was associated with improvements in suicidal ideation and behaviour and reductions in hospitalizations. Qualitative studies suggest a Safety Planning intervention is acceptable and feasible, as well as adaptable to the clinical area in its modality and delivery. Despite positive outcomes, this intervention has not been fully evaluated in French settings. A previous study concluded it was not adapted to emergency department due to a lack of time or available exam rooms for professionals to conduct the intervention. Therefore, in our study, participants will be recruited in a post-ED unit, where patients are monitored for maximum 72 hours, before being discharged home or transferred to hospital facilities.

Safety planning is a collaborative intervention between a healthcare worker and the patient, by which a series of preventive actions are planned in the event patient experiences suicide ideation. Safety planning included identifying: 1) warning signs or triggers that indicate suicide ideation is likely to occur, 2) internal coping strategies (e.g., distracting activities) for use when those triggers occur or when experiencing suicide ideation, 3) social contacts for further distraction or social locations that may provide distraction, 4) supportive contacts (who can provide assistance), 5) emergency resources (e.g., therapist phone numbers, hotlines, local hospital emergency room locations), and also included steps to ensure the safety of the home environment that minimize the patient's ability to act on suicidal thoughts or urges (i.e., reducing access to lethal means).

In this study, Safety plan was delivered face-to-face, during the post-ED stay; upon discharge, participants were provided with the paper-based plan they completed with their physician.

The main outcome of our study was to evaluate the feasibility - assessed by healthcare workers- and the acceptability - from patients' point of view- of conducting a Safety plan in a post-ED setting, after suicidal attempt. Secondary outcomes included to evaluate Safety plan utility, assessed by patients based on their use or not of the Safety plan at 1 and 6 months after inclusion, and its efficacy, on the recurrence of suicidal attempt over the 6 months after inclusion.
