People who die by suicide without having attended hospital-based psychiatric care: Who are the ones that do not seek help?

BACKGROUND

Little is known regarding those who die by suicide without having received help. The aim of this study was to compare those who died by suicide without having attended psychiatric care with controls (a) with a psychiatric diagnosis and (b) from the general population.

METHODS

Cases were all individuals 15+ who lived in Denmark during 2010-2021 and had died by suicide without having attended hospital-based psychiatric care. Cases were matched to controls from the two comparison-groups using a 1:10 ratio and compared using age-and sex-adjusted logistic regression analyses. Geographical variations in psychiatric care utilization were examined.

RESULTS

Among 7119 individuals who died by suicide, 3474 (48.8 %) had not attended psychiatric care. Compared to controls with a psychiatric diagnosis, cases were more likely to be male (OR, 3.9, 95% CI, 3.6-4.2), older (80+ years: OR, 10.7, 95 % CI, 9.2-12.5), have lost a close relative (OR, 1.8, 95 % CI, 1.3-2.6) or recently retired (OR, 1.4, 95 % CI, 1.0-1.1.8). Compared to controls from the general population, cases were associated with male sex (OR, 4.6, 95 % CI, 4.2-5.0), living alone (OR, 2.3, 95 % CI, 2.2-2.5), unemployment (OR, 2.1, 95 % CI, 1.8-2.5), as well as having lost a close relative (OR, 5.0, 95 % CI, 3.5-7.2) or divorced within the last 1 year (OR, 3.6, 95 % CI, 2.7-4.9).

LIMITATIONS

Characteristics and preceding events were limited to available register data.

CONCLUSIONS

About half of all who died by suicide had not attended psychiatric care. Being older, male, or exposed to recent stressors were some of the major markers when compared to controls.

A Scoping Review of Digital-Based Intervention for Reducing Risk of Suicide Among Adults

Suicide is a serious public health problem, especially among adults. Risk factors for suicide include the presence of mental health disorders, history of previous suicide attempts; substance or alcohol use and lack of social support. The impact of suicide risk includes psychological loss, as well as the trauma and emotional stress that can be felt by the families and communities left behind. Digital interventions have emerged as a promising alternative for suicide risk prevention. Previous research has focused on the findings of various designs, which did not provide clear intervention information to inform the implementation of the intervention. This study aims to describe a digital intervention to reduce the risk of suicidal behavior in adults. The design used in this study was a scoping review. The authors conducted a literature search from the Scopus, PubMed, and CINAHL databases. Inclusion criteria in this study were articles discussing digital interventions aimed at preventing suicide risk in adult populations, English language, full-text, RCT or quasi-experiment design, and publication period of the last 10 years (2014-2024). The major keywords used in the article search were suicide prevention, digital intervention, and adults. Data extraction used manual table and data analysis used descriptive qualitative with a content approach. The results showed that there were 9 articles that discussed digital-based interventions to reduce suicide risk in adults. The various types of digital interventions used were smartphone apps, online learning modules, and game-based interventions. These interventions offer significant potential in reducing the risk of suicidal behavior in adults. Digital interventions have an important role in reducing the risk of suicidal behavior in adults by considering aspects of suitability to individual needs and understanding digital literacy. Then, the development of mental health services and public health policies presented needs to be done with collaboration between stakeholders in suicide prevention efforts.

The Development, Progress, and Impact of National Suicide Prevention Strategies Worldwide

National suicide prevention strategies have been identified as evidence-informed interventions that require multisectoral efforts by governments. This article reviews the rationale for national strategies, the need for a whole-of-government approach, and current progress on national strategies worldwide, including successes and challenges regarding implementation. We highlight the limitations of existing evidence and describe how future research may help to address knowledge gaps. We conclude that national strategies are an important tool for suicide prevention worldwide. However, a more robust evidence base evaluating the impact of strategies on suicide-related outcomes is needed.

Implementation of Complex Suicide Prevention Interventions: Insights into Barriers, Facilitators and Lessons Learned

INTRODUCTION

Effective suicide prevention interventions are infrequently translated into practice and policy. One way to bridge this gap is to understand the influence of theoretical determinants on intervention delivery, adoption, and sustainment and lessons learned. This study aimed to examine barriers, facilitators and lessons learned from implementing complex suicide prevention interventions across the world.

METHODS AND MATERIALS

This study was a secondary analysis of a systematic review of complex suicide prevention interventions, following updated PRISMA guidelines. English published records and grey literature between 1990 and 2022 were searched on PubMed, CINAHL, PsycINFO, ProQuest, SCOPUS and CENTRAL. Related reports were organized into clusters. Data was extracted from clusters of reports on interventions and were mapped using the updated Consolidated Framework for Implementation Research.

RESULTS

The most frequently-reported barriers were reported within the intervention setting and were related to the perceived appropriateness of interventions within settings; shared norms, beliefs; and maintaining formal and informal networks and connections. The most frequently reported facilitators concerned individuals' motivation, capability/capacity, and felt need. Lessons learned focused on the importance of tailoring the intervention, responding to contextual needs and the importance of community engagement throughout the process.

CONCLUSION

This study emphasizes the importance of documenting and analyzing important influences on implementation. The complex interplay between the contextual determinants and implementation is discussed. These findings contribute to a better understanding of barriers and facilitators salient for implementation of complex suicide prevention interventions.

The Cost-Effectiveness of Psychosocial Interventions Following Self-Harm in Australia

Background: Psychosocial interventions following self-harm in adults, in particular cognitive behavioral therapy (CBT), can be effective in lowering the risk of repeated self-harm. Aims: To evaluate the cost-effectiveness of CBT for reducing repeated self-harm in the Australian context. Method: The current study adopted the accessing cost-effectiveness (ACE) approach using return-on-investment (ROI) analysis. Uncertainty and sensitivity analyses (Sas) tested the robustness of the model outputs to changes in three assumptions: general practitioner referral pathway (SA1), private setting intervention delivery (SA2), and training costs (SA3). Results: The intervention produced cost savings of A$ 46M (95% UI -223.7 to 73.3) and A$ 18.3M (95% UI -86.2 to 24.6), subject to the effect of intervention lasting 2- or 1-year follow-up. The ROI ratio reduced to 5.22 in SA1 (95% UI -10.1 to 27.9), 2.5 in SA2 (95% UI -4.8 to 13.3), and 5.1 in SA3 (95% UI -9.8 to 27.8). Limitations: We assumed that the effectiveness would reduce 50% within 5 years in the base case, and we used Australian data and a partial social perspective. Conclusions: The current study demonstrated cost-effectiveness of CBT for adults who have self-harmed with the return-on-investment ratio of A$ 2.3 to $6.0 for every A$ 1 invested.

Using Virtual Patients to Assess and Improve Clinicians' Emotional Self-awareness: a Randomized Controlled Study

OBJECTIVE

Working with suicidal patients can elicit negative emotional responses that can impede clinicians' empathy and affect clinical outcomes. Virtual human interactions represent a promising tool to train clinicians. The present study investigated the impact of virtual human interaction training to enhance clinicians' emotional self-awareness and empathy when working with suicidal patients.

METHODS

Clinicians were randomly assigned into two groups. Both groups interviewed a virtual patient presenting with a suicidal crisis; clinicians in the intervention condition (n = 31) received immediate feedback about negative emotional responses and empathic communication, whereas those in the control condition (n = 33) did not receive any feedback. All clinicians interviewed a second virtual patient 1 week later. Clinicians' emotional response to the two virtual patients and their empathic communication with each of them were assessed immediately after each interaction. Linear mixed models were used to assess change in clinicians' emotional response and verbal empathy between the two interactions across conditions.

RESULTS

Clinicians' emotional responses toward the suicidal virtual patients were unchanged in both conditions. Clinicians in the intervention condition presenting low empathy level with the first virtual patient showed higher empathy level with the second virtual patient than with the first (B = 1.15, SE = 0.25, p < 0.001, 95% CI [0.42, 1.89]).

CONCLUSIONS

This work demonstrates the feasibility of using virtual human interactions to improve empathic communication skills in clinicians with poor empathy skills. Further refinement of this methodology is needed to create effective training modules for a broader array of clinicians.

Experiences of suicide survivors of sharing their stories about suicidality and overcoming a crisis in media and public talks: a qualitative study

BACKGROUND

Media stories of hope and recovery from suicidal ideation have been found to have a positive impact on the audience, but little is known about how individuals who share their own experiences perceive the effects of their storytelling. This study aimed to assess qualitatively, through focus groups, how individuals who shared their personal story of hope and recovery in the media and public talks experienced the process, and which aspects they perceived as important in sharing their coping story.

METHODS

Three focus groups were conducted with a total of n = 12 individuals. These included n = 5 participants with experience of suicidal ideation or a suicide attempt, n = 4 individuals who had been bereaved through suicide, and n = 3 participants who experienced both. Participants were recruited from the American organisation "Suicide Survivors United". Thematic analysis was used to assess the participants' perception and experiences of sharing their story.

RESULTS

Participants shared that the intention to help others was the main motivation to share their story of hope and recovery. Participants noted many positive effects of their storytelling on themselves and also received positive feedback from the audience, such as improved help-seeking attitudes. The participants offered recommendations for those who want to share their story of hope and recovery, including careful personal preparation and media training before going public. They also discussed media recommendations for talking about suicide in the media.

CONCLUSIONS

Sharing a personal story of hope and recovery may have a beneficial impact on the storytellers. Storytelling requires a careful preparation and training before going public and support and guidance is crucial in all stages of the storytelling, particularly to help unexperienced storytellers in going public and using their personal narratives to help prevent suicide.

Psychic Pain Among Men: Factor Structure, Psychosocial Correlates, and Mediation of Social Connectedness and Suicidal Ideation

ABSTRACT

The Psychic Pain Scale (PPS) measures a form of mental pain involving overwhelming negative affect and loss of self-control. Understanding psychic pain among men is needed to advance efforts for preventing male suicide. The present study examined the factor structure and psychosocial correlates of the PPS among 621 online help-seeking men. Confirmatory factor analysis indicated a higher-order factor comprising affect deluge and loss of control factors. Psychic pain evinced significant associations with general psychological distress, r = 0.64; perceived social support, r = -0.43; social connectedness, r = -0.55; and suicidal ideation, r = 0.65 (all p 's < 0.001)-the latter three remained significant after controlling for general distress. Psychic pain also mediated the association between social disconnection and suicidal ideation (standardized indirect effect = -0.14 [-0.21, -0.09]), after controlling for social support and distress. Findings support the PPS as a promising measure for investigating psychic pain among men and indicate psychic pain as a link between social disconnection and suicidal ideation.

Defining the Characteristics of an e-Health Tool for Suicide Primary Prevention in the General Population: The StopBlues Case in France

With over one million deaths per year in the world, suicide is a major public health problem that could be significantly reduced by effective prevention programs. E-health tools are of particular interest for primary prevention as they can address a broad population including people unaware of their own risk and provide information and help without the fear of stigma. Our main objective was to define the overall characteristics of an e-health tool for suicide primary prevention in the French general population by defining the characteristics of the IT features; the content of the information delivered; the best way to structure it; and how it should be relayed and by whom. The research was carried out through a literature review and a co-construction phase with stakeholders. Four types of strategies may guide the construction of e-health tools for suicide primary prevention: education and awareness, (self-)screening, accessing support, and mental health coping. They should be accessible on different devices to reach the most users, and language and content should be adapted to the target population and to the issue being addressed. Finally, the tool should be consistent with ethical and quality best practices. The e-health tool StopBlues was developed following those recommendations.

Lithium in the prevention of suicide in adults: systematic review and meta-analysis of clinical trials

Controversy exists regarding the efficacy of lithium for suicide prevention. Except for a recent trial that enrolled over 500 patients, available trials of lithium for suicide prevention have involved small samples. It is challenging to measure suicide in a single randomised controlled trial (RCT). Adding a single large study to existing meta-analyses may provide insights into lithium's anti-suicidal effects. We performed a meta-analysis of RCTs comparing lithium with a control condition for suicide prevention. MEDLINE and other databases were searched up to 30 November 2021. Efficacy was assessed by calculating the summary Peto odds ratio (OR) and incidence rate ratio (IRR) with 95% confidence intervals. Among seven RCTs, the odds of suicide were lower among patients receiving lithium versus control (OR = 0.30, 95% CI 0.09-1.02; IRR = 0.22, 95% CI 0.05-1.05), although the findings were still not statistically significant. The role of lithium in suicide prevention remains uncertain.

A Volunteer-Run, Face-to-Face, Early Intervention Service for Reducing Suicidality

Background: Befriending is one of many strategies with the potential to reduce suicidal ideation and decrease the risk of suicide. Aims: To measure change in suicidal ideation and behavior among visitors (service users) supported at The Listening Place (TLP), a charity which offers volunteer-run, face-to-face befriending to people who are suicidal. Method: This study was peer reviewed and preregistered on the Open Science Framework prior to data extraction. Anonymized data were extracted for visitors at the point of referral and after 3 months of receiving support. Paired-sample tests were used to test whether self-reported suicidal ideation and behaviors changed after 3 months of support from TLP. Multivariable regressions were used to test whether change in suicidal feelings was associated with demographic characteristics or baseline self-reported suicidality. Results: TLP received 13,938 referrals from July 2016 to February 2022. Self-reported suicidal ideation, suicidal behavior, and feelings of distress decreased after 3 months, while feelings of support increased. Only self-reported suicidal behavior prior to referral was associated with a lesser reduction in self-reported suicidality after 3 months. Limitations: In the absence of a control group, it cannot be concluded that TLP causes the reduction in self-reported suicidality. Conclusions: An empathetic, nonjudgmental, listening service for people who are feeling suicidal was well received by users, who experienced a reduction in suicidality.

A virtual, pilot randomized trial of a brief intervention to prevent suicide in an integrated healthcare setting

OBJECTIVE

Patients who die by suicide are often seen in primary care settings in the weeks leading to their death. There has been little study of brief interventions to prevent suicide in these settings.

METHOD

We conducted a virtual, pilot, randomized controlled trial of a brief suicide prevention strategy called Veterans Affairs Brief Intervention and Contact Program (VA BIC) in patients who presented to a primary care mental health walk-in clinic for a new mental health intake appointment and were at risk for suicide. Our primary aim was to assess feasibility. We measured our ability to recruit 20 patients. We measured the proportion of enrolled patients who completed all study assessments. We assessed adherence among patients assigned to VA BIC.

RESULTS

Twenty patients were enrolled and 95% (N = 19) completed all study assessments. Among the 10 patients assigned to VA BIC, 90% (N = 9) of patients completed all required intervention visits, and 100% (N = 10) completed ≥70% of the required interventions visits.

CONCLUSION

It is feasible to conduct a virtual trial of VA BIC in an integrated care setting. Future research should clarify the role of VA BIC as a suicide prevention strategy in integrated care settings using an adequately powered design.

The Colorado National Collaborative: A public health approach to suicide prevention

OBJECTIVE

Suicide rates in the United States have risen dramatically during the 21st century despite national, state and local level commitments to prevention, improvements in the development and delivery of evidence-informed prevention approaches, and advances in epidemiological capacity to identify areas for targeted intervention. Complex problems require comprehensive solutions. In Colorado, that solution is a comprehensive, integrated public health collaboration that aligns diverse community and programmatic efforts across the prevention continuum. The Colorado National Collaborative (CNC) is pursuing a real-world test of the public health approach to suicide prevention by helping community coalitions deliver a package of evidence-informed activities in geographically defined community systems.

METHODS

The CNC began by identifying six diverse Colorado counties with high suicide rates or number of deaths. Working closely with community, state, and national partners, CNC identified existing community-level risk and protective factors, programs, and policies. This process provided insight on the overlay between existing efforts and identified burden centers and drivers.

RESULTS

The CNC team identified six components for strategic implementation: (1) connectedness, (2) economic stability and supports, (3) education and awareness, (4) access to suicide safer care, (5) lethal means safety, and (6) postvention. Evaluation is being conducted through a collaborative, participatory, and empowerment approach that incorporates stakeholders as leaders in all aspects of the process.

CONCLUSION

The CNC includes data-driven identification of populations at risk of suicide, community identification of protective factors, and true collaboration between prevention experts at the national, state, and local level in implementing a comprehensive approach to prevention. Lessons learned are discussed.

Effects at 3 months of a large-scale simulation-based training for first year medical residents on the knowledge of suicide

BACKGROUND

Suicide is a leading yet underestimated cause of death in the world and in France. The goal of our study was to determine the impact at 3 months of a large-scale simulation program on suicide risk assessment for first-year medical residents.

METHODS

All the first-year medical residents participated in the simulation program that included a session on suicide risk assessment. The scenario was carried out by a standardized patient (professional actor) who had a normal check-up at the ER after a chest pain. He verbalized suicidal thoughts to an ER nurse due to a recent divorce and social difficulties, who then reported it to the resident. The latter had to assess suicide risk on his own. The QECS "Questionnaire de connaissances relatives au suicide" was used to assess knowledge of suicide before the training session (T0) and 3 months later (T1). A pre/post comparison was performed with a paired t-test.

RESULTS

420 residents participated in this study. A total of 273 matching questionnaires was obtained. A statistically significant theoretical knowledge improvement was found at 3 months of the session for all the residents.

LIMITATIONS

The absence of a control group and data loss were some of the major limitations of our study. Another limitation corresponds to the lack of additional questions, such as levels of interest, former and recent training, level of experience, attitudes, and self-competency in suicide risk assessment before and after the simulation program that could have helped to interpret the obtained results and their variation. Moreover, the exact effects of this increased knowledge on clinical practice has not been measured in our study.

CONCLUSION

This is an unprecedented, large-scale attempt in France to allow all the medical residents to practice suicide risk assessment. This simulation-based training had a positive impact at 3 months on the knowledge of suicide in medical residents.

Suicidology Post Graduate Curriculum: Priority Topics and Delivery Mechanisms for Suicide Prevention Education

BACKGROUND

There has been limited attention to the development and delivery of tertiary suicide prevention curricula. The aim of this work was to describe the status of postgraduate suicide prevention education, with specific attention on examining the needs of the suicide prevention sector in Australia.

METHOD

An online survey was completed by 76 stakeholders in Australia. Current curriculum learning outcomes from Griffith University's postgraduate suicidology programs guided the development of the survey.

RESULTS

Four key learning domains were rated highest in importance by stakeholders. According to most stakeholders, skills-based qualifications were the most relevant type of qualification, and online modulized education was the most preferred delivery mode. Half of stakeholders supported suicide prevention professional development through a combination of financial support and study leave.

CONCLUSIONS

The survey provided invaluable feedback regarding the priorities of Australia's suicide prevention sector for content domains and delivery mechanisms for tertiary suicidology education. The findings showed the preferred type of organizational (employer) support that may be provided for employees to undertake such education. These findings will inform the future developments of Griffith University's suicidology programs and may motivate other universities to consider offering same or a similar type of education to support the suicide prevention sector toward saving lives.

Dos and Don'ts in Designing School-Based Awareness Programs for Suicide Prevention

Abstract.Background: Despite the promising evidence for the effectiveness of school-based awareness programs in decreasing the rates of suicidal thoughts and suicide attempts in young people, no guidelines on the targets and methods of safe and effective awareness programs exist. Aims: This study intends to distill recommendations for school-based suicide awareness and prevention programs from experts. Method: A three-stage Delphi survey was administered to an expert panel between November 2018 and March 2019. A total of 214 items obtained from open-ended questions and the literature were rated in two rounds. Consensus and stability were used as assessment criteria. Results: The panel consisted of 19 participants in the first and 13 in the third stage. Recommended targets included the reduction of suicide attempts, the enhancement of help-seeking and peer support, as well as the promotion of mental health literacy and life skills. Program evaluation, facilitating access to healthcare, and long-term action plans across multiple levels were among the best strategies for the prevention of adverse effects. Limitations: The study is based on opinions of a rather small number of experts. Conclusion: The promotion of help-seeking and peer support as well as facilitating access to mental health-care utilities appear pivotal for the success of school-based awareness programs.

Iran's National Suicide Prevention Program

Background and Aims: Iran is one of the few countries in the Eastern Mediterranean Region (EMR) to have developed a national suicide prevention program (NSPP). This report introduces Iran's NSPP to policy planners and researchers working in suicide prevention, and is intended to encourage other low- and middle-income countries to develop, implement, and evaluate their own NSPPs. Method: This was a case study of a NSPP in one country, integrating quantitative and qualitative data. Bibliographic searches were conducted using both international and national databases, supplemented by other documents. The study benefited from the experiential evidence provided by the senior author. Results: While the national incidence of suicide is low, there are higher rates among young adults, particularly women, in western regions. In 2010, Iran's NSPP was integrated into primary health care. A rigorous evaluation of Iran's suicide prevention program concluded that Iran has the potential to take a leadership role in suicide prevention within the EMR, although several challenges were identified. Limitation: The findings of this case study cannot be generalized to other contexts. Conclusion: Given Iran's unstable situation, the NSPP needs to be monitored, evaluated, and adjusted according to evidence and ongoing changing national and local needs.

Reducing youth suicide: systems modelling and simulation to guide targeted investments across the determinants

BACKGROUND

Reducing suicidal behaviour (SB) is a critical public health issue globally. The complex interplay of social determinants, service system factors, population demographics, and behavioural dynamics makes it extraordinarily difficult for decision makers to determine the nature and balance of investments required to have the greatest impacts on SB. Real-world experimentation to establish the optimal targeting, timing, scale, frequency, and intensity of investments required across the determinants is unfeasible. Therefore, this study harnesses systems modelling and simulation to guide population-level decision making that represent best strategic allocation of limited resources.

METHODS

Using a participatory approach, and informed by a range of national, state, and local datasets, a system dynamics model was developed, tested, and validated for a regional population catchment. The model incorporated defined pathways from social determinants of mental health to psychological distress, mental health care, and SB. Intervention scenarios were investigated to forecast their impact on SB over a 20-year period.

RESULTS

A combination of social connectedness programs, technology-enabled coordinated care, post-attempt assertive aftercare, reductions in childhood adversity, and increasing youth employment projected the greatest impacts on SB, particularly in a youth population, reducing self-harm hospitalisations (suicide attempts) by 28.5% (95% interval 26.3-30.8%) and suicide deaths by 29.3% (95% interval 27.1-31.5%). Introducing additional interventions beyond the best performing suite of interventions produced only marginal improvement in population level impacts, highlighting that 'more is not necessarily better.'

CONCLUSION

Results indicate that targeted investments in addressing the social determinants and in mental health services provides the best opportunity to reduce SB and suicide. Systems modelling and simulation offers a robust approach to leveraging best available research, data, and expert knowledge in a way that helps decision makers respond to the unique characteristics and drivers of SB in their catchments and more effectively focus limited health resources.

Firearm Suicides in the Elderly: A Narrative Review and Call for Action

Firearm suicides are one of the leading causes of death for older Americans. The purpose of this review is to explore the risk factors associated with suicides in the elderly, provide an overview of the epidemiology of firearm-related suicides in older Americans, and explore methods of preventing firearm suicides in the elderly. The vast majority (70 %) of elderly suicides in the U.S were committed using a firearm. Elderly firearm suicides have increased by 49 % between 2010 and 2018, disproportionately affecting white males. Yearly firearm suicides in the elderly ranged from 4,276 in 2010 to 6,375 in 2018. In 2018, the rate of elderly male firearm suicides was 24.96/100,000 compared to a rate of 1.92/100,000 for elderly females, a rate ratio of 13 to 1 for males compared to females. The primary risk factors for elderly firearm suicides seem to be physical illnesses, mental illnesses, and social factors. Older Americans engage in suicidal behaviors with greater planning and lethality of intent than do young adults. Of all the strategies to prevent suicides with firearms, the most efficacious measures based on current research seem to be state firearm legislation and improving mental healthcare, but these effects are not specific to the elderly. Strengthening state firearm laws and improving mental healthcare for the elderly may have promise in preventing elderly firearm-related suicides. Additional implications for practice and research are discussed in this review.

The Impact of Infectious Disease-Related Public Health Emergencies on Suicide, Suicidal Behavior, and Suicidal Thoughts

Abstract. Background: Infectious disease-related public health emergencies (epidemics) may increase suicide risk, and high-quality evidence is needed to guide an international response. Aims: We investigated the potential impacts of epidemics on suicide-related outcomes. Method: We searched MEDLINE, EMBASE, PsycInfo, CINAHL, Scopus, Web of Science, PsyArXiv, medRxiv, and bioRxiv from inception to May 13–16, 2020. Inclusion criteria: primary studies, reviews, and meta-analyses; reporting the impact of epidemics; with a primary outcome of suicide, suicidal behavior, suicidal ideation, and/or self-harm. Exclusion criteria: not concerned with suicide-related outcomes; not suitable for data extraction. PROSPERO registration: #CRD42020187013. Results: Eight primary papers were included, examining the effects of five epidemics on suicide-related outcomes. There was evidence of increased suicide rates among older adults during SARS and in the year following the epidemic (possibly motivated by social disconnectedness, fears of virus infection, and concern about burdening others) and associations between SARS/Ebola exposure and increased suicide attempts. A preprint study reported associations between COVID-19 distress and past-month suicidal ideation. Limitations: Few studies have investigated the topic; these are of relatively low methodological quality. Conclusion: Findings support an association between previous epidemics and increased risk of suicide-related outcomes. Research is needed to investigate the impact of COVID-19 on suicide outcomes.

Suicide and Suicide Prevention From a Global Perspective

Abstract. In this introductory chapter, we provide the background and rationale for the compilation of overviews of national suicide prevention strategies from all geographic regions globally. Currently, suicide is the second leading cause of death among young people aged 15–29 years at global level. Overall, suicide rates in low- and middle-income countries (LMIC) are lower than the rates in high-income countries (HIC) of 11.2 per 100,000 compared with 12.7 per 100,000 population, but the majority of suicide deaths worldwide occur in LMICs. However, there are ongoing challenges in relation to the accuracy of suicide figures in many countries. The rationale for the global approach to suicide prevention is linked to major strategic documents provided by the WHO, including the Global Mental Health Action Plan, 2013–2020, the WHO report Preventing Suicide: A Global Imperative, in 2014, and the United Nations Sustainable Development Goals (SDGs) for 2030, including a target of reducing premature mortality from noncommunicable diseases by one-third, with suicide mortality rate identified as an indicator for this target. In addition, a review is provided of the evidence base and best practice of suicide prevention programs.
