Objectives: Safety barriers to prevent suicide by jumping were removed from Grafton Bridge in Auckland, New Zealand, in 1996 after having been in place for 60 years. This study compared the number of suicides due to jumping from the bridge after the reinstallation of safety barriers in 2003. Methods: National mortality data for suicide deaths were compared for three time periods: 1991–1995 (old barrier in place); 1997–2002 (no barriers in place); 2003–2006 (after barriers were reinstated…

Effectiveness of restricting access to a suicide jump site: a test of the method substitution hypothesis

The decline in bridge suicide without persistent shifts in deaths to other bridges provides evidence that restricting access to one highly lethal method is effective, and may reflect a broader decline in suicide.

Installation of a bridge barrier as a suicide prevention strategy in Montréal, Québec, Canada.

Little or no displacement to other jumping sites may occur after installation of a barrier at an iconic site such as Jacques-Cartier Bridge, suggesting a barrier's design is important to its effectiveness and should be considered for new bridges with the potential to become symbolic suicide sites.

Effect of a barrier at Bloor Street Viaduct on suicide rates in Toronto: natural experiment

This finding suggests that Bloor Street Viaduct may not have been a uniquely attractive location for suicide and that barriers on bridges may not alter absolute rates of suicide by jumping when comparable bridges are nearby.

Means restriction for the prevention of suicide by jumping.

A meta-analysis of all studies assessing jumping means restriction interventions showed a directionality of effect in favour of the interventions, as evidenced by a reduction in the number of suicides at intervention sites, as well as the cost-effectiveness of interventions.

Comparing Different Suicide Prevention Measures at Bridges and Buildings: Lessons We Have Learned from a National Survey in Switzerland

The analyses revealed that barriers of at least 2.3 m in height and safety-nets fixed significantly below pedestrian level deterred suicidal jumps, and secured bridgeheads and inbound angle barriers seemed to enhance the effectiveness of the measure.

Suicidal behaviour and suicide from the Clifton Suspension Bridge, Bristol and surrounding area in the UK: 1994-2003.

There is little difference in the characteristics of people jumping from different locations and barriers may prevent suicides among people at lower risk of repeat self-harm, but staff at suicide hotspots can make an important contribution to the effectiveness of installations to prevent suicide by jumping.

Recent Advances in Means Safety as a Suicide Prevention Strategy

Overall, means safety efforts and preventative measures seem to be promising ways to reduce the national suicide rate if implemented, but cultural and practical barriers will need to be taken into consideration when implementing these plans.

Analysis of the Cost Effectiveness of a Suicide Barrier on the Golden Gate Bridge

Cost-benefit analysis suggests that a suicide barrier on the GGB would result in a highly cost-effective reduction in suicide mortality in the San Francisco Bay Area.

Interventions to reduce suicides at suicide hotspots: a systematic review

There is relatively strong evidence that reducing access to means can avert suicides at hotspots without substitution effects, and the evidence is weaker for the other approaches, although they show promise.



Effectiveness of Barriers at Suicide Jumping Sites: A Case Study

The findings appear to strengthen the case for installation of safety barriers at suicide sites in efforts to prevent suicide deaths, and also suggest the need for extreme caution about the removal of barriers from known jumping sites.

Effect of barriers on the Clifton suspension bridge, England, on local patterns of suicide: implications for prevention

There was no evidence of an increase in male suicide by jumping from other sites in the Bristol area after the erection of the barriers after the effect of the installation of barriers was assessed.

Suicides associated with the Jacques Cartier Bridge, Montreal, Quebec 1988-1993: descriptive analysis and intervention proposal.

Based on a review of the effectiveness of preventive measures, it is proposed to limit access to jumping by means of a fence along the bridge railing by the Jacques Cartier Bridge in Montreal.

Current studies on youth suicide in Singapore and a national study on parasuicide are urgently needed to increase the understanding of these phenomena.

Suicide acts in 8 states: incidence and case fatality rates by demographics and method.

Poisoning and firearm were the most common methods used among those attempting suicide and those completing suicide acts, respectively and the most lethal method was firearm.
