Abstract: Background: Hanging is a frequent suicide method, but developing measures to prevent suicide by this method is particularly challenging. The aim of this study is to gain new knowledge that would enable the design of effective of measures that would help prevent suicide by hanging. Methods: A total of 6,497 suicides registered across the eight Swiss Forensic Institutes (IRM) were analysed. Of these, 1,282 (19.7%) persons hung themselves. T-test and chi-square tests. and chi-square tests were used to analyse …(or determine, or investigate) …group differences regarding sociodemographic variables and triggers Findings: Men and women who hung themselves showed no significant differences in sociodemographic variables. However, women were significantly more likely to have a psychiatric illness history, whereas men were more likely to have somatic diagnoses. In controlled environments, people used shelves, plumbing and windows more often than beams, pipes, bars and hooks to hang themselves. Compared with other suicide methods, hanging was more likely to have been triggered by partner and financial problems. Conclusions: Suicide by hanging can be best prevented in institutions (e.g. psychiatric hospitals, somatic hospitals, prisons). These institutions should be structurally evaluated and modified with a primary focus on sanitary areas, windows and shelves. Otherwise, it is important to use general suicide prevention measures, such as awareness raising and staff training in medical settings, low-threshold treatment options and regular suicide risk assessment for people at risk.
