摘要

Suicide is a leading cause of premature mortality in low and high income countries. Despite this, information to guide prevention strategies is limited. One of the few approaches with a strong evidence base is preventing access to methods that are highly lethal and commonly used in suicidal acts.1 The rationale for this approach is based in four observations: suicide attempts are often impulsive, crises are often fleeting, prognosis is good after non-fatal attempts (<100/o of people go on to die by suicide), and acts are more likely to be fatal when highly lethal methods are used.Placing barriers on bridges and other sites from which suicide by jumping is common therefore seems sensible. Jumping is highly lethal and deaths are often very public,2 leading to media reporting and possible contagion.3 Reviews and national guidelines have called for safety measures at "suicide hotspots."In the linked study, Sinyor and colleagues describe the apparent failure of the Bloor Street Viaduct barrier in Toronto to reduce suicide by jumping.7 They assessed the yearly rates of suicide by jumping at the Bloor Street Viaduct from 1993 to 2001 (nine years before the barrier) and from July 2003 to June 2007 (four years after the barrier). Although the barrier prevented suicides from the bridge-deaths fell from 9.3 a year to zero-this had no effect on the rates of suicide by jumping in the region as a whole (although suicide rates overall fell); indeed, there was a possible compensatory rise in suicides from other bridges.
