Abstract

Objective : Among the postcrisis suicide prevention programmes, brief contact interventions (BCIs) have been proven to be efficient. VigilanS generalizes to a whole French region a BCI combining resource cards, telephone calls and sending postcards, according to a predefined algorithm. However, a major problem in suicide prevention is the suicide reattempt, which can lead to final suicide. Here, we analyse the suicide reattempt in VigilanS. Methods : The study concerned patients included in VigilanS over the period from 1 st January 2015 to 31 December 2018, with an end of follow-up on 1 st July 2019. We performed a series of descriptive analyses, survival curves and regressions. The outcome was the suicide reattempt, and the predictive variables were the characteristics of the patient at entry and during follow-up in VigilanS. Age and sex were considered as adjustment variables. Results : 11879 inclusions occurred during the study period, corresponding to 10666 different patients, among which 905 reattempted suicide. More than half were primary suicide attempters (53.4%). A significant relationship with suicide reattempt was identified for the following characteristics : being a non-primary suicide attempter, having attempted suicide by voluntary drug intoxication and phlebotomy, alcohol consumption among primary suicide attempters, and having no companion at the Accepted manuscript : Authors’ Copy ETHICS APPROVAL AND CONSENT TO PARTICIPATE emergency room visit among non-primary suicide attempters. Hanging (as suicide method), having made no call to VigilanS were protective factors. Conclusion : This study provides us with a valuable insight into the profiles of patients repeating a SA, which is important for suicide prevention in general.
