Résumé
Madrid Introduction Sleep disturbances are associated with an increased risk of suicidal behavior. The evidence primarily stems from studies based on questionnaires about sleep quality and duration. In recent years, the availability of wearable health technology has increased and offers an inexpensive, appealing, and accessible way to measure sleep. Our aim is to assess the feasibility and acceptability of wearable sleep tracking monitoring devices in a sample of suicide attempters and healthy controls. Methods A prospective, open-label, 12-months study will be conducted in the emergency department (ED) and psychiatric unit (PU) of the University Hospital of Brest, France. Inclusion criteria are male or female, aged 18 or over, surviving a suicide attempt, discharged from ED or PU, with an Internet connection via Wi-Fi, and giving consent. The sleep tracker and a smartphone will be given to the patient after discharge. He or she will receive brief training on how to use the sleep tracker. Patient will be asked to monitor their sleep during the two weeks following the discharge. The feasibility will be explored by analysing the data proceeding from the sleep tracker. The acceptability will be assessed during the two-weeks follow up visit, using a standardized questionnaire. We also will perform a similar assessment in a group of 10 healthy controls recruited via announcement in social networks. Results : Preliminary results of this ongoing study show that feasibility and acceptance may be related to technical features of wearable devices. Discussion A better understanding of the bidirectional mechanism between sleep disturbances and suicide behavior will allow the design of tailored interventions to prevent suicide attempts.
