The objective of the VigilanS system is to reduce the risk of a repeat suicide attempt, by establishing a telephone link – and sometimes by postcard – during the six months following the persons concerned’s discharge from hospital. According to a recently published study, carried out by Public Health France, this program is effective: the risk of recurrence drops by almost 40% among people who have benefited from such support in the 12 months following their suicide attempt, compared to those who have not benefited from it.
