“…Any movement in that region beyond the arrival of trains would send an alert to station staff. Similarly, 2 other studies described a similar approach at a cliff located in Sydney, Australia [ 5 , 7 ]. Unlike the metro station, this outdoor site was much larger and with extremely uneven geography, leading to less complete CCTV coverage.…”

“…Suicides in public places can attract media attention, potentially introducing a degree of “notoriety” about a specific location, and thus increase its frequency of use [ 4 ]. Furthermore, these incidents can adversely affect bystanders [ 5 ]. Thus, efforts to prevent suicide in public places are of particular importance.…”

Background Suicide is a recognized public health issue, with approximately 800,000 people dying by suicide each year. Among the different technologies used in suicide research, closed-circuit television (CCTV) and video have been used for a wide array of applications, including assessing crisis behaviors at metro stations, and using computer vision to identify a suicide attempt in progress. However, there has been no review of suicide research and interventions using CCTV and video. Objective The objective of this study was to review the literature to understand how CCTV and video data have been used in understanding and preventing suicide. Furthermore, to more fully capture progress in the field, we report on an ongoing study to respond to an identified gap in the narrative review, by using a computer vision–based system to identify behaviors prior to a suicide attempt. Methods We conducted a search using the keywords “suicide,” “cctv,” and “video” on PubMed, Inspec, and Web of Science. We included any studies which used CCTV or video footage to understand or prevent suicide. If a study fell into our area of interest, we included it regardless of the quality as our goal was to understand the scope of how CCTV and video had been used rather than quantify any specific effect size, but we noted the shortcomings in their design and analyses when discussing the studies. Results The review found that CCTV and video have primarily been used in 3 ways: (1) to identify risk factors for suicide (eg, inferring depression from facial expressions), (2) understanding suicide after an attempt (eg, forensic applications), and (3) as part of an intervention (eg, using computer vision and automated systems to identify if a suicide attempt is in progress). Furthermore, work in progress demonstrates how we can identify behaviors prior to an attempt at a hotspot, an important gap identified by papers in the literature. Conclusions Thus far, CCTV and video have been used in a wide array of applications, most notably in designing automated detection systems, with the field heading toward an automated detection system for early intervention. Despite many challenges, we show promising progress in developing an automated detection system for preattempt behaviors, which may allow for early intervention.

FRs reported that responding to MHC was 'babysitting', frustrating and a waste of time and resources, reporting that it damaged their public image.…”

Subjective experiences of the first response to mental health crises in the community: a qualitative systematic review

ObjectiveTo review and synthesise qualitative studies that have explored subjective experiences of people with lived experience of mental health-related illness/crisis (MHC), their families and first responders.DesignA systematic review of qualitative evidence was conducted. English-language articles exploring the content of interactions and participants’ experiences were included.Data sourcesMEDLINE, PsycINFO, EMBASE, CINAHL; Google Scholar, SAGE journals, Science Direct and PubMed.Data extraction and synthesisTwo reviewers read and systematically extracted data from the included papers. Papers were appraised for methodological rigour using the Critical Appraisal Skills Programme Qualitative Checklist. Data were thematically analysed.ResultsWe identified 3483 unique records, 404 full-texts were assessed against the inclusion criteria and 79 studies were included in the qualitative synthesis. First responders (FRs) identified in studies were police and ambulance staff. Main factors influencing response are persistent stigmatised attitudes among FRs, arbitrary training and the triadic interactions between FRs, people with mental illness and third parties present at the crisis. In addition, FR personal experience of mental illness and focused training can help create a more empathetic response, however lack of resources in mental health services continues to be a barrier where ‘frequent attenders’ are repeatedly let down by mental health services.ConclusionLack of resources in mental healthcare and rise in mental illness suggest that FR response to MHC is inevitable. Inconsistent training, complexity of procedures and persistent stigmatisation make this a very challenging task. Improving communication with family carers and colleagues could make a difference. Broader issues of legitimacy and procedural barriers should be considered in order to reduce criminalisation and ensure an empathetic response.

“…Ross et al report trends in suicide deaths at a hotspot site (Gap Park, Sydney, Australia), where a multilevel means restriction strategy (The Gap Park Self-Harm Minimisation Masterplan) has been implemented [3]. A novel mixed-methods approach was used to evaluate the effectiveness of the Masterplan in the years following its implementation in 2010.…”
