BackgroundThe implementation of a surveillance program after a suicide attempt (SA) is a very innovative step in the evolution of our system of care. It was interesting to know if we observe a decline in suicide attempts in the region, in particular of recurrences of SA. MethodWe measured the evolution of the number of suicide attempts before and after implantation of VigilanS, using two types of analysis: a first from the national medical information systems in Medicine-Surgery-Obstetrics (PMSI-MCO) and a second from the collection of the ER stays for SA in the hospitals involved in the VigilanS program. ResultsIn 2014 (year before start of VigilanS), a total of 10 119 ER stays for SA was observed (5626 women and4463 men); in 2017, the total was 9.230 stays for SA (5047 women and 3 839 men), representing a decrease of 13.5%. The reduction was balanced between men (−14%) and women (−10%). Based on the figures of PMSI, we see an acceleration of the reduction of stay for SA in the Nord-Pas-de-Calais after 2014 (−16% instead of −6%), instead of the two Picardy departments the most comparable which show a degradation of the phenomenon (+13%), and opposed to the Department of the Oise which shows a stable maintenance of the current decline (−12%). ConclusionThese two indicators are imperfect, but evolution over three years since the implementation of VigilanS goes in the same direction. We find a uncoupling of a hospital stay in connection with a SA. The intensity of this decline seems correlated to the penetrance of the program.
