Abstract

Summary: We assessed the effect of the installation of barriers on the Clifton suspension bridge, Bristol, England, in 1998 on local suicides by jumping. Deaths from this bridge halved from 8.2 per year (1994–1998) to 4.0 per year (1999–2003; P=0.008). Although 90% of the suicides from the bridge were by males, 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. This study provides evidence for the effectiveness of barriers on bridges in preventing site-specific suicides and suicides by jumping overall in the surrounding area.

  • The construction of barriers and fencing at high-risk jumping sites, especially bridges, can lead to a reduction in the number of suicides by this method.

    “A range of studies have demonstrated that the construction of barriers and fencing at high-risk jumping sites, especially bridges, can lead to a reduction in the number of suicides by this method (Beautrais 2001;Bennewith 2007;Pelletier 2007;Pirkis 2013;Pirkis 2015).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
