Examen des meilleures pratiques de postvention : méthode Delphi

Abstract

BackgroundPostvention aims to implement services adapted to the needs of a population that may be vulnerable after suicide. While a plethora of postvention programs exist, they are generally based less on solid evidence than on the judgment of health professionals. Using the Delphi method, an Australian study obtained a consensus among experts as to which postvention actions are to be engineered in a postvention program. Since no similar study has been carried out for programs in French-speaking countries, it seemed important to reproduce the same type of study and to compare the respective results. The present study is aimed at establishing a French inventory of postvention actions and at achieving a consensus among experts as to the actions to be included in a postvention program. MethodsA systematic review of the scientific literature (PRISMA method) and the gray literature (documentation on the WEB) made it possible to identify the different actions that have been included in various postvention programs. Using the DELPHI method, experts endeavored to assess their relevance. ResultsAn inventory of 190 postvention actions was established and they were classified according to a sequential axis (pre-event, at the time of the event, and post-event), according to type of action (environment-centered or people-centered). The experts identified 128 actions to be included in a postvention program. ConclusionConvergence was observed among the experts, as they identified the practices to be encouraged following a suicide. When comparing the results in French-speaking countries to the 548 actions selected in the Australian study, we observe similarities between the two studies regarding types of postvention actions. This study provides an update for health professionals on the most relevant practices to be included in a postvention program.
