Abstract

Purpose: To investigate whether two novel interventions on a bridge - a Video Incident Detection System (VIDS) and spinning bar barriers - have an impact on suicidal behaviour on the bridge.

Methods: A total of 146 suicidal acts were retrieved for analyses; 108 interventions before suicidal acts, 35 suicide deaths and 3 suicide attempts. Incident rate ratios (IRR) were calculated to estimate the change in incident rate associated with implementation of the two interventions: VIDS and the spinning bar 2-metre high barrier.

Results: The results of the Poisson regression showed that the rate of suicide deaths, after installation the VIDS, did not change significantly (IRR: 1.23, 95% Confidence Interval [95% CI]: 0.59-2.56), although the rate of intervened suicidal acts increased (IRR: 2.40, 95% CI: 1.65-3.47). The results showed that subsequent spinning bar installation resulted in a decrease in the incident rate of intervened suicidal acts (IRR: 0.37, 95% CI: 0.25-0.57) as well as suicide deaths (IRR: 0.23, 95% CI: 0.07-0.71). Comparison of the period when both interventions were in place with the period with no interventions indicated a reduction in suicide deaths (IRR: 0.28, 95% CI: 0.10-0.82), but no change in intervened suicidal acts (IRR: 0.90, 95% CI: 0.59-1.38).

Conclusion: The rate of suicide death decreased after the installation of the spinning bar barrier but not after the implementation of VIDS alone. Our findings reinforce that restricting access to means is a highly effective way of preventing suicide on bridges and that spinning bars may be a helpful way to design barriers.

在韩国一座桥上进行干预后自杀行为事件的变化。

目的：调查桥梁上的两种新型干预措施--视频事件检测系统（VIDS）和旋转栏杆障碍--是否会对桥上的自杀行为产生影响：方法：共收集了 146 起自杀行为进行分析；其中 108 起是在自杀行为发生前采取的干预措施，35 起是自杀死亡，3 起是自杀未遂。计算了事件发生率比（IRR），以估算与实施两种干预措施相关的事件发生率变化：结果：泊松回归结果显示，安装 VIDS 后，自杀死亡率没有显著变化（IRR：1.23，95% 置信区间 [95%CI]：0.59-2.56），但自杀行为干预率有所上升（IRR：2.40，95% CI：1.65-3.47）。研究结果表明，随后安装的旋转栏降低了自杀行为的干预率（IRR：0.37，95% CI：0.25-0.57）和自杀死亡率（IRR：0.23，95% CI：0.07-0.71）。将采取两种干预措施的时期与未采取干预措施的时期进行比较，结果显示自杀死亡率有所下降（IRR：0.28，95% CI：0.10-0.82），但干预后的自杀行为没有变化（IRR：0.90，95% CI：0.59-1.38）：结论：安装旋转栏栅后，自杀死亡率有所下降，但仅在实施 VIDS 后，自杀死亡率并没有下降。我们的研究结果进一步证明，限制获得自杀工具是预防桥上自杀的一种非常有效的方法，而旋转栏杆可能是设计障碍物的一种有用方法。

期刊介绍： Social Psychiatry and Psychiatric Epidemiology is intended to provide a medium for the prompt publication of scientific contributions concerned with all aspects of the epidemiology of psychiatric disorders - social, biological and genetic. In addition, the journal has a particular focus on the effects of social conditions upon behaviour and the relationship between psychiatric disorders and the social environment. Contributions may be of a clinical nature provided they relate to social issues, or they may deal with specialised investigations in the fields of social psychology, sociology, anthropology, epidemiology, health service research, health economies or public mental health. We will publish papers on cross-cultural and trans-cultural themes. We do not publish case studies or small case series. While we will publish studies of reliability and validity of new instruments of interest to our readership, we will not publish articles reporting on the performance of established instruments in translation. Both original work and review articles may be submitted.
