Suicide Prevention

Effectiveness of early and intensive intervention on suicide prevention: CARS programme

The aim of this study was to evaluate the outcomes of the Programme for Management of Suicidal Behaviour and Suicide Prevention (CARS). Individuals treated in the emergency department of University Hospital Marqués de Valdecilla for suicidal thoughts or attempts (N = 401) between 1-March-2016 and 31-December-2018 were considered. No randomization by patients or groups was performed. Student's t-test, chi-square and repeated measure analysis of variance were used. Kaplan-Meier survival function and Cox proportional hazard regression models were employed to estimate the risks of relapse. Outcome of those who voluntary enrol CARS were compared with treatment as usual (TAU) at 6- and 12-months follow-up. The results indicate a significant reduction and delayed occurrence of suicidal behaviour over a 12-month follow-up period with the CARS programme compared to TAU, along with a decreased frequency of hospital admissions. CARS programme demonstrates a substantial impact, significantly reducing the risk of recurrent suicidal behaviour by 35.5 % and the risk of repeated suicidal attempts by 47.2 % at the 12-month follow-up. The programme exhibits a dual protective effect, diminishing suicidal behaviour and fostering improved long-term outcomes. In conclusion, CARS effectively reduced suicidal behaviour recurrence, achieving significant decreases in suicidal thoughts, plans and attempts.

A Review of Systematic Reviews: Gatekeeper Training for Suicide Prevention with a Focus on Effectiveness and Findings

OBJECTIVES

Suicide prevention gatekeeper training (GKT) is considered an important component of an overall suicide-prevention strategy. The primary aim of this study was to conduct the first robust review of systematic reviews of GKT to examine the overall effectiveness of GKT on knowledge, self-efficacy, attitudes, behavioral intentions, and behavioral change. The study also examined the extent to which outcomes were retained long term, the frequency of refresher sessions, and the effectiveness of GKT with Indigenous populations and e-learning delivery.

METHODS

For this review of reviews, MEDLINE, PsycINFO, Embase; and the Cochrane Database of Systematic Reviews were searched. ROBIS was applied to assess risk of bias and findings were synthesized using narrative synthesis.

RESULTS

Six systematic reviews were included comprising 61 studies, of which only 10 were randomized controlled trials (RCTs). Immediate positive effects of GKT on knowledge, skills, and self-efficacy were confirmed, including for interventions tailored for Indigenous communities. Evidence was mixed for change in attitude; few studies measured e-learning GKT, retention of outcomes, booster sessions, behavioral intentions, and behavioral change, with some positive results.

CONCLUSIONS

Evidence supports the immediate effects of GKT but highlights a need for more high-quality RCTs, particularly for Indigenous and e-learning GKT. This review identified a concerning lack of long-term follow-up assessments at multiple time points, which could capture behavioral change and a significant gap in studies focused on post-training interventions that maintain GKT effects over time.

Suicide Prevention Programming: Comparing Four Prominent Frameworks

OBJECTIVE

Suicide is a significant public health concern. About 48,000 individuals died by suicide in 2021 in the United States, and approximately one in 100 deaths globally are due to suicide. Continuing efforts in program development and evaluation are vital to preventing suicide. Multiple frameworks have been developed to reduce suicide rates, but they have not been compared to assess their comprehensiveness, nor have their components been classified.

METHODS

In 2019, the authors conducted a narrative review of the literature and identified four major frameworks for suicide prevention: the U.S. Department of Veterans Affairs (VA) Suicide Prevention Program, the Defense Suicide Prevention Program of the U.S. Department of Defense, Zero Suicide in Health and Behavioral Health Care, and the technical package developed by the Centers for Disease Control and Prevention. Program components for these frameworks were identified and classified by using two prevention strategy classification systems: the National Academy of Medicine's (NAM's) continuum-of-care model and the Substance Abuse and Mental Health Services Administration's (SAMHSA's) prevention model.

RESULTS

The cross-program comparison revealed that no single program included all components of suicide prevention programs. However, the VA program was the most comprehensive in terms of the number of components and their spread across prevention strategy classifications. The programs used few components categorized under NAM's promotion or selective prevention strategy classifications. The SAMHSA prevention strategy classifications of information dissemination, community-based processes, and positive alternatives were also used infrequently.

CONCLUSIONS

Organizations, health care systems, and policy makers may use these findings as they develop, improve, and implement suicide prevention programs.

Review of Australia's funding commitments for suicide prevention from 2021-22 to 2026-27

Objective Examine the distribution of funding for suicide prevention in Australia from 2021-22 to 2026-27. Methods Government websites were reviewed to locate budget documents related to suicide prevention funding. Information was extracted on the program/service to be funded, and the funder entity, duration, and year allocation. Extracted data was reviewed to identify commonly targeted sub-populations. Results The majority of suicide prevention-related funding was allocated to aftercare for persons who have attempted suicide, consistent with the effectiveness of these services, followed by programs targeting the general population. Little funding was allocated to other specific sub-populations, such as young people and Aboriginal and Torres Strait Islander peoples. The amount of funding allocated to suicide prevention varied across jurisdictions, which is only partially explained by suicide rates. Conclusions There is a need for greater investment in care for specific sub-populations who are at higher risk of suicide. This study provides a baseline for comparing future investments in suicide prevention in Australia.

Factors associated with suicide in people who use drugs: a scoping review

BACKGROUND

Suicide is a significant contributor to global mortality. People who use drugs (PWUD) are at increased risk of death by suicide relative to the general population, but there is a lack of information on associated candidate factors for suicide in this group. The aim of this study was to provide a comprehensive overview of existing evidence on potential factors for death by suicide in PWUD.

METHODS

A scoping review was conducted according to the Arksey and O'Malley framework. Articles were identified using Medline, CINAHL, PsycINFO, SOCIndex, the Cochrane Database of Systematic Reviews and the Campbell Collaboration Database of Systematic Reviews; supplemented by grey literature, technical reports, and consultation with experts. No limitations were placed on study design. Publications in English from January 2000 to December 2021 were included. Two reviewers independently screened full-text publications for inclusion. Extracted data were collated using tables and accompanying narrative descriptive summaries. The review was reported using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews (PRISMA-ScR) guidelines.

RESULTS

The initial search identified 12,389 individual publications, of which 53 met the inclusion criteria. The majority (87%) of included publications were primary research, with an uncontrolled, retrospective study design. The most common data sources were drug treatment databases or national death indexes. Eleven potential factors associated with death by suicide among PWUD were identified: sex; mental health conditions; periods of heightened vulnerability; age profile; use of stimulants, cannabis, or new psychoactive substances; specific medical conditions; lack of dual diagnosis service provision; homelessness; incarceration; intravenous drug use; and race or ethnicity. Opioids, followed by cannabis and stimulant drugs were the most prevalent drugs of use in PWUD who died by suicide. A large proportion of evidence was related to opioid use; therefore, more primary research on suicide and explicit risk factors is required.

CONCLUSIONS

The majority of studies exploring factors associated with death by suicide among PWUD involved descriptive epidemiological data, with limited in-depth analyses of explicit risk factors. To prevent suicide in PWUD, it is important to consider potential risk factors and type of drug use, and to tailor policies and practices accordingly.

Attempted suicide: does lethality matter?

OBJECTIVES

To investigate whether high-lethality suicide attempters align to the demographic and clinical features observed in completed suicide in the national and international literature, and whether low-lethality attempters more closely align with the clinical profile of non-attempter ideators.

METHODS

A retrospective chart review of adult suicide ideators and attempters presenting to an urban tertiary care hospital was performed. Suicide ideators (n = 50) and attempters (n = 50) were coded for variables including demographics and clinical characteristics (e.g. psychiatric diagnosis and previous suicide attempt). Method and lethality of suicide attempt were coded using the medical Lethality Rating Scale.

RESULTS

High-lethality attempters were more likely to be younger in age than low-lethality attempters (p = 0.026) and ideators (p = 0.041). The lethality scores of suicide attempts were significantly inversely correlated with age (p = 0.017).

CONCLUSIONS

Our study adds to the small but increasing body of literature investigating the characteristics of high-lethality suicide attempters and suggests younger adult age is a risk factor for a high-lethality attempt. Further understanding of this unique group would be aided by widespread agreement on the definition of a high-lethality suicide attempt and longitudinal studies of this cohort.

Suicide stigma and suicide literacy among Bangladeshi young adults: a cross-sectional study

Introduction

Suicide is one of the leading causes of death worldwide. Owing to poor suicide literacy, people are not aware of the consequences of the suicide stigma, which may affect individuals. This study aimed to examine the status of suicide stigma and literacy among young adults in Bangladesh.

Methods

This cross-sectional study included 616 male subjects and female subjects residing in Bangladesh aged between 18 and 35 years who were invited to complete an online survey. Suicide literacy and suicide stigma among the respondents were assessed by using the validated Literacy of Suicide Scale and Stigma of Suicide Scale, respectively. Other independent variables that have been found to affect suicide stigma or literacy were included in this study based on prior research. Correlation analysis was used to assess the relationships between the study's main quantitative variables. Multiple linear regression models were used to assess factors affecting suicide stigma and suicide literacy, respectively, after controlling for covariates.

Results

The mean literacy score was 3.86. The participants' mean scores in the stigma, isolation, and glorification subscale were 25.15, 14.48, and 9.04, respectively. Suicide literacy was negatively associated with stigmatizing attitudes (p = 0.005). Male subjects, unmarried/divorced/widowed, less educated (below HSC), smokers, less exposure to suicide, and respondents with chronic mental illness had lower suicide literacy and more stigmatizing attitudes.

Conclusion

The findings suggest that addressing suicide literacy and stigma by developing and executing awareness programs on suicide and mental health among young adults may increase knowledge, decrease stigma, and hence prevent suicide among this population.

Suicidal ideation among people with Parkinson's disease and comparison with a control group

BACKGROUND

Detection of suicidal ideation (SI) is key for trying to prevent suicide. The aim of this study was to analyze the frequency of SI and related factors in Spanish people with Parkinson's Disease (PwPD) and to compare them with a control group.

METHODS

PD patients and controls recruited from the Spanish cohort COPPADIS from January 2016 to November 2017 were included. Two visits were conducted: V0 (baseline); V2 (2-year ± 1 month follow-up). SI was defined as a score ≥1 on item nine of the Beck Depression Inventory-II (BDI-II). Regression analyses were conducted to identify factors related to SI.

RESULTS

At baseline, 693 PwPD (60.2% males; 62.59 ± 8.91 years old) and 207 controls (49.8% males; 60.99 ± 8.32 years old) were included. No differences between PwPD and controls were detected in SI frequency at either V0 (5.1% [35/693] vs. 4.3% [9/207]; p = 0.421) or at V2 (5.1% [26/508] vs. 4.8% [6/125]; p = 0.549). Major depression (MD) and a worse quality of life were associated with SI at both visits in PwPD: V0 (MD, OR = 5.63; p = 0.003; PDQ-39, OR = 1.06; p = 0.021); V2 (MD, OR = 4.75; p = 0.027; EUROHIS-QOL8, OR = 0.22; p = 0.006). A greater increase in the BDI-II total score from V0 to V2 was the only factor predicting SI at V2 (OR = 1.21; p = 0.002) along with an increase in the total number of non-antiparkinsonian drugs (OR = 1.39; p = 0.041).

CONCLUSION

The frequency of SI (5%) in PwPD was similar to in controls. Depression, a worse quality of life, and a greater comorbidity were related to SI.

Association Between History of Psychiatric Disorder and Degree of Physical Injury Among Suicide Attempters: Secondary Data Analysis in a Japanese Rural Area

INTRODUCTION

While there may be differences in the choice of suicide methods between attempters with and those without a history of psychiatric disorders, it is not clear whether these differences predict the actual degree of physical injury. The present study aimed to investigate the association between the history of psychiatric disorder and the degree of physical injury among suicide attempters in a Japanese rural area.

METHODS

We conducted a cross-sectional study analyzing secondary data of 806 suicide attempters from April 2012 to March 2022 obtained from a Japanese rural city. The exposure variable was a history of psychiatric disorders. The primary outcome was the degree of physical injury of suicide attempters: moderate and severe. We conducted a multivariate Poisson regression analysis to estimate the prevalence ratios (PRs) and 95% confidence intervals (CIs).

RESULTS

Among 806 suicide attempters, a significant negative association between the history of psychiatric disorder and the degree of physical injury was observed (PR = 0.40; 95% CI, 0.28-0.59). Those with and without psychiatric disorders were more likely to choose low- and severe-lethality suicide methods such as drug or psychotropic overdoses and hanging or deep wrist injuries, respectively (P < .001).

CONCLUSIONS

The present study highlights the importance of considering suicide attempters, both with and without psychiatric disorders, while formulating targeted suicide prevention strategies.

Psychometric Properties of the Suicidal Ideation Scale in the Indonesian Language

INTRODUCTION

Suicide is one of the leading cause of mortality among adolescents and young adults, especially in low to middle-income countries. Research found that screening for suicidal ideation in non-clinical populations such as schools or communities is an important step toward preventing suicide. Despite so, not all screening tools have the capabilities to accurately detect suicidal ideation among adolescents and young adults in non-clinical populations. The Suicidal Ideation Scale (SIS) is one of the most used questionnaires to measure suicidal thoughts in non-clinical populations. This study aims to investigate the psychometric properties of SIS among adolescents and young adults in Indonesia, especially in non-clinical populations.

METHODS

After a series of language and cultural adaptations, 1254 senior high school and university students completed the Indonesian version of SIS using 3 standard questionnaires, namely Patient Health Questionnaire-9/PHQ-9, Beck Depression Inventory-II/BDI-II, and Children's Depression Inventory/CDI. The SIS content validity, internal consistency, test-retest reliability and concurrent, as well as internal structure validity, were investigated using content validity index (CVI), Cronbach's Alpha, Pearson product-moment correlation, and confirmatory factor analysis (CFA), respectively.

RESULTS

The result showed that SIS has good to excellent internal consistency and test-retest reliability. Based on the validity indicators, it has satisfactory content and convergent validity, and further support the one-factor and 2-factor model for factorial validity. Both one-factor and 2 factor model are suitable to use in non-clinical settings.

CONCLUSIONS

SIS is a valid and reliable tool for suicide ideation screening in adolescents and young adults in non-clinical populations. This validated questionnaire can be used in the early detection of suicidal ideation among adolescents and young adults in non-clinical populations, thus contributing to developing strategies and policies to prevent suicide among Indonesian adolescents and young adults at group and institutional levels.

Completed Suicide Linked to the COVID-19 Pandemic by Using the Psychological Autopsy Method in Sibiu County, Romania: Case Series and Literature Review

The COVID-19 pandemic is associated with suicide, as some data suggests. Our study aims to investigate the emergence of eleven completed suicide cases suspected to be linked to the COVID-19 pandemic during the restrictive measures imposed by the Romanian government, and to identify the consequences of mental health, suicidal motivation, and behavioral changes. To this end, we analyzed the deceased's medical records and applied the psychological autopsy method to the relatives/caregivers of the deceased for a suicidal investigation history, within conducted free-flow discussions. To highlight behavioral changes that occurred in the distant antecedents as well as immediately before the suicidal act, we used two sets of closed questions comprised of fifteen alarm signs, including depressive and/or anxiety symptoms. Our results showed that a deterioration of the mental status, especially concerning depressive and anxiety symptoms, was evident in people without or with pre-existing psychiatric pathology. The suicidal motivation proved to be complex including, in addition to the SARS-CoV-2 infection, social and economic consequences of the COVID-19 pandemic. We noted an intensification of the investigated alarm signs and even the emergence of new warning signs in the recent antecedents. Based on our findings, we reaffirmed the important role of the psychological autopsy method in suicide investigation, proving that it can detect the specific impact of the COVID-19 pandemic on people prone to suicide. This impact can be psycho-emotional, social, and/or economical, and thus we can state that the COVID-19 pandemic and its consequences can be, at least, a triggering factor that enhances completed suicide risk. Further studies are needed in this particular area because correlations between the COVID-19 pandemic and completed suicide do not appear to be accidental.

Lessons to be learned: identifying high-risk medication and circumstances in patients at risk for suicidal self-poisoning

Background

Although the total number of suicides decreased since the beginning of the 1980s, the number of suicide-related behaviors using self-intoxication increased. Therefore, research on the characteristics of individuals committing self-intoxication becomes of growing importance for risk assessments and the development of preventive measures.

Methods

In this prospective, observational, monocentric cohort study, all incoming calls at our Poisons Control Centre reporting suicide-related behaviors through self-intoxication, were analyzed via a standardized questionnaire over 12 months. Both univariate and bivariate analyses were performed.

Results

1238 cases of deliberate intoxication were included in the study. The majority of cases occurred in the age group between 18 and 44 (n = 607/49%), two-thirds were female (n = 817/66%). The main substances used were antidepressants (n = 420/34%), peripheral analgesics (n = 322/26%) and neuroleptics (n = 282/23%). The majority of patients ingested substances from their prescribed medication (n = 640/82%) with the highest proportion in those aged over 64 years (n = 72/113; 91%, p < 0.001). Substance use was reported for the minority of patients (n = 175/23%). For 704 cases (79%), a psychiatric disorder was documented. Factors associated with recurrent suicide-related behaviors were an underlying psychiatric disorder (OR = 6.2; 95% CI 3.8–10.4), substance use (OR = 2.4; 95% CI 1.5–3.8), and ingestion of neuroleptics (OR = 2.1, 95% CI 1.4–3.0) or antidepressants (OR = 1.6; 95% CI 1.2–2.3).

Conclusion

This study might contribute to identifying individuals with an increased risk of suicide-related behaviors by deliberate intoxication and to developing preventive strategies for future suicide attempt(s).

Connectedness, Self-Esteem, and Prosocial Behaviors Protect Adolescent Mental Health Following Social Isolation: A Systematic Review

Societal trends and COVID-19 quarantines have increased the number of adolescents experiencing social isolation, placing them at heightened risk for mental health issues. The aim of this review is to explore protective factors that might mitigate psychological harm in the presence of social isolation. A systematic literature review was conducted using Fink's step-by-step process. Four library databases were searched, and results were reported using PRISMA. Of the 246 studies reviewed, 12 studies were retained following the quality assessment. The sample includes 14,064 participants from USA, Australia, and Europe, ranging from 10-19 years old. Social connectedness (ie., family connectedness, school connectedness, social support), self-esteem, and prosocial behaviors were the most common protective factors to social isolation. Additional factors such as self-efficacy, optimism, and ethnic identity are discussed. Implications for future research are recommended, including the need to explore spiritual, biological, and sociocultural factors influencing social connectedness and mental health in adolescents.

Effectiveness of gatekeepers' training for suicide prevention program among medical professionals and medical undergraduate students of a medical college from Western India

INTRODUCTION

Suicide risk among Indigenous populations is a multifaceted phenomenon, influenced by biological, psychological, and social factors at the individual level, as well as cultural, political, and economic issues at the family and community level. The global prevalence of depression among medical students was recently estimated to be 28.0 % according to a meta-analysis of 77 studies. In the field of suicide prevention, the term gatekeeper refers to "individuals in a community who have face-to-face contact with large numbers of community members as part of their usual routine." They may be trained to "identify persons at risk of suicide and refer them to treatment or supporting services as appropriate". In our study we aimed to improved attitude and knowledge in gatekeeper to improve detection and referral of individuals who are at risk of suicide.

METHODS AND MATERIAL

We adapted an evidence-based gatekeeper training into a two-hour, multi-modal and interactive event for medical professional and undergraduate students. Then we evaluated the intervention compared to free-recall knowledge and attitudes questions were examined before and after participation in a student and faculty gatekeeper training program. Focus groups with students enriched interpretation of quantitative results.

STATISTICAL ANALYSIS USED

Knowledge, attitudes, and skills of both students and teachers were analyzed by Mann-Whitney U-test. Comparison of knowledge, attitudes, and skills between both groups was analyzed by Wilcoxon signed-rank test.

RESULTS

Undergraduate students developed more positive attitude for suicidal behavior where faculties developed more confident in their skill after training sessions.

CONCLUSION

brief gatekeeper training found effective in improving knowledge about suicide. Also, increasing participants' accuracy to identify warning signs, risk factors and protective factors about suicide.

Risk factors for completed suicide among people who use drugs: A scoping review protocol

Background: Research over the past several decades has shown an increased risk for completed suicide among people who use drugs (PWUD). However, no study to date has attempted to summarise the available literature on the variety of risk factors associated with this increased risk. This paper presents a protocol for a scoping review that aims to systematically map and synthesise the extent and nature of published, unpublished and grey literature related to risk factors for suicide among PWUD.

Methods: The following six-stage methodological framework for scoping reviews proposed by Arksey and O’Malley with enhancements by Levac and colleagues will be used: (1) identifying the research question, (2) identifying relevant studies, (3) study selection, (4) charting/mapping the data, (5) collating, summarising and reporting results and (6) expert consultation. The review will be conducted and reported in accordance with the PRISMA Extension for Scoping Reviews (PRISMA-ScR). Key inclusion and exclusion criteria will be developed to guide literature screening and data charting. Three reviewers will conduct the initial screening of published, unpublished and grey literature. Identified risk factors will be collated, summarised and categorised iteratively by two independent reviewers. Stakeholder consultation will occur with experts from a national steering committee, a national advisory group, a national suicide prevention centre and a European drug monitoring centre.

Conclusion: Collating and thematically categorising the various risk factors for suicide among this high-risk group will hold important implications for future research, policy and practice. The research will be disseminated through publication in a peer-reviewed academic journal and a conference presentation, and by sharing the findings with key stakeholders working within research, policy-making and professional practice contexts.

Racial/Ethnic Differences in Preceding Circumstances of Suicide and Potential Suicide Misclassification Among US Adolescents

PURPOSE

There is a paucity of research on racial/ethnic differences in preceding circumstances of suicide among adolescents aged 10-19 years and consequential potential misclassification of suicide deaths (i.e., manner of death classified as injury of undetermined intent). This study (1) examined preceding circumstances of suicide among non-Hispanic White, non-Hispanic Black, non-Hispanic Asian/Pacific Islander (A/PI), non-Hispanic American Indian/Alaskan Native (AI/AN), and Hispanic adolescent decedents; and (2) investigated potential suicide misclassification of racial/ethnic minority decedents.

METHODS

We used data from the 2006-2015 National Violent Death Reporting System Restricted Access Database. Multivariable logistic regression analyses examined differences in depressed mood, mental health problem and treatment, crisis in the past 2 weeks, problems with school, intimate partner, family relationship, and other relationships (e.g., friend) among racial/ethnic minority decedents compared to White decedents. A separate logistic regression analysis assessed potential suicide misclassification of racial/ethnic minority decedents relative to White counterparts.

RESULTS

Adjusting for sex and suicide history and circumstances, all racial/ethnic minority decedents had significantly lower odds of documented mental health problem and treatment compared to White decedents. Racial/ethnic differences in relationship problems were also identified. Black decedents had significantly higher odds of manner-of-death classification as undetermined intent than did White decedents, suggesting greater likelihood of suicide misclassification.

CONCLUSIONS

Circumstances contributing to suicide among adolescents differ by race/ethnicity, indicating the need for culturally tailored suicide prevention efforts.

Variable Circumstances of Suicide Among Racial/Ethnic Groups by Sex and Age: A National Violent-Death Reporting System Analysis

Suicide rates vary by race/ethnicity, but little is known about how the circumstances that contribute to suicide differ across racial/ethnic groups. This study investigated suicide circumstances among non-Hispanic Whites, non-Hispanic Blacks, non-Hispanic Asian/Pacific Islanders, non-Hispanic Native American/Alaskan Natives, and Hispanics by sex and age. Using de-identified National Violent Death Reporting System (NVDRS) Restricted Access Database files from 2006-2015, we examined proximal circumstances of suicide among decedents aged 10 years and older. Hierarchical logistic regression analysis revealed racial/ethnic differentials in non-alcohol substance abuse problem, intimate partner problem, and physical health problem across sex and age, controlling for potential confounders. Study findings highlight priority areas for suicide interventions.

Trends in the Incidence and Lethality of Suicidal Acts in the United States, 2006 to 2015

Importance

Understanding changes in the incidence rates and lethality of suicidal acts may explain increasing suicide rates.

Objective

To examine trends in the incidence rates and lethality of suicidal acts from 2006 to 2015 among persons aged 10 to 74 years.

Design, Setting, and Participants

This cross-sectional study was conducted from May 2, 2018, to January 30, 2019. Medically treated nonfatal suicide attempts were identified from the 2006 to 2015 Nationwide Inpatient Sample and Nationwide Emergency Department Sample databases. Suicides were identified from the 2006 to 2015 mortality files of the National Vital Statistics System.

Main Outcomes and Measures

The incidence rate of suicidal acts was calculated by dividing the number of total suicidal acts by the US population. Lethality was measured through the case fatality rates (CFRs) of suicidal acts by dividing the number of suicides by the total number of suicidal acts.

Results

A total of 1 222 419 (unweighted) suicidal acts, which included both suicides and nonfatal suicide attempts, were identified from 2006 to 2015. Overall, the incidence rates of total suicidal acts increased 10% from 2006 to 2015 (annual percentage change [APC], 0.8%; 95% CI, 0.3%-1.3%), and the CFRs of suicidal acts increased 13% during the 2006 to 2015 period (APC, 2.3%; 95% CI, 1.3%-3.3%). In subgroup analyses, incidence rates increased by 1.1% (95% CI, 0.6%-1.6%) per year for female individuals during the 2006 to 2015 period but remained stable for male individuals. The CFRs increased for both sexes (APC, 5.0% [95% CI, 3.1%-6.9%] since 2010 for female individuals; 1.6% [95% CI, 0.6%-2.5%] since 2009 for male individuals). Incidence rates increased among adolescents from 2011 to 2015 and among older adults aged 65 to 74 years throughout the 2006 to 2015 period. Conversely, the CFRs increased since 2009 among persons aged 20 to 44 years (APC, 3.7%; 95% CI, 2.5%-5.0%) and since 2012 for those aged 45 to 64 years (APC, 2.7%; 95% CI, 0.0%-5.4%). Persons aged 20 to 44 years and 45 to 64 years experienced increases in suicidal acts by more lethal means, whereas adolescents and older adults aged 65 to 74 years showed increased incidence by all means.

Conclusions and Relevance

This study found increased suicidal acts among female persons, adolescents, and older adults aged 65 to 74 years, implying the need to address emerging or exacerbating suicide risk factors for these populations. The findings on the increased lethality particularly among persons aged 20 to 64 years highlighted the need to reduce access to materials that could be used as lethal means among persons at risk of suicide. These findings on population-level epidemiologic patterns can be used to guide the development of comprehensive suicide prevention strategies.

Barriers for the Research, Prevention, and Treatment of Suicidal Behavior

Efforts in research, prevention, and treatment of suicidal behavior have produced mixed results. One of the main barriers to combating suicidal behavior lies in the very conceptualization of suicide, a phenomenon that is at once sociological, psychiatric, and even philosophical, and one that has not always been included in the field of health care. There are also many barriers at the social level, ranging from stigma against people with suicidal behavior to stigma towards psychiatric care, as well as the controversial role of the media. The media plays an important role in society and depending on its attitude it can be either beneficial or harmful in our fight against suicidal behavior. Differences between countries - in the provision of resources, in the way of understanding the phenomenon or in the manner of providing official figures - pose an additional challenge to suicide prevention on a global level. In the field of research, predicting suicidal behavior by identifying effective risk markers is severely hampered by the low occurrence of suicide in the population, which limits the statistical power of studies. The authors recommend combining various risk factors to build predictive models. This, in addition to employing increasingly precise machine learning techniques, is a step in the right direction, although there is still a long way to go before the expected results can be obtained. Finally, adequate training of health professionals, both specialized and non-specialized, as well as gatekeeper training, is crucial for implementing suicide prevention strategies in the population.

Comportamento suicida e estratégias de prevenção sob a ótica de professores

RESUMO Objetivo Analisar conhecimentos sobre comportamento suicida e estratégias de prevenção adotadas por professores do ensino fundamental. Método Estudo qualitativo, apoiado na pesquisa-ação, realizado em escola pública do município de Teresina, Piauí, Brasil. Participaram nove professores de ensino fundamental. Realizaram-se três encontros, uma reunião de negociação e dois seminários temáticos. Os discursos foram submetidos à análise temática. Resultados O conhecimento dos professores acerca do comportamento suicida envolveu identificação dos sinais de alerta, tendo a automutilação como atitude suicida mais recorrente. Como estratégias apontaram a necessidade de prevenção por meio da identificação do aluno em risco, da observação, do diálogo, do monitoramento e utilização de redes de apoio. Os desafios elencados pelos professores foram a inabilidade na identificação e associação dos sinais de alerta com o comportamento suicida, a dificuldade na abordagem do aluno em crise, a ausência de equipe de saúde mental nas escolas e de temas transversais nos currículos escolares. Conclusão e implicações para a prática Observa-se a necessidade de ações voltadas para a capacitação desses profissionais, tendo em vista sua posição privilegiada para promoção de ambientes saudáveis, bem como para prevenção e identificação dos adolescentes em risco, com manejo adequado e encaminhamento compartilhado aos serviços de saúde.

Using Youth Participatory Action Research as a Health Intervention in Community Settings

Youth participatory action research (YPAR) emphasizes positive youth development by engaging young people as co-researchers and change agents on complex issues to produce solutions that are relevant to youth. YPAR has primarily been used in classroom and youth organization settings, which means there are very few examples of its usage in other community-based settings or as a health intervention approach. Additionally, there is a need for further study of YPAR implementation processes and the effect on youth development and well-being outcomes. In this article, we highlight the innovative use of YPAR as a community-based health intervention through two case studies in which the adolescent health issues of physical activity and suicide were addressed. We describe the design of each YPAR health intervention and the studies that were conducted to link participatory research processes to youth development and health outcomes. Using the lessons learned from these YPAR interventions, we propose best practices for the design, implementation, and evaluation of YPAR as a health intervention strategy in a community setting.

Suicide Prevention: An Emerging Priority For Health Care

Suicide is a significant public health problem. It is the tenth leading cause of death in the United States, and the rate has risen in recent years. Many suicide deaths are among people recently seen or currently under care in clinical settings, but suicide prevention has not been a core priority in health care. In recent years, new treatment and management strategies have been developed, tested, and implemented in some organizations, but they are not yet widely used. This article examines the feasibility of improving suicide prevention in health care settings. In particular, we consider Zero Suicide, a model for better identification and treatment of patients at risk for suicide. The approach incorporates new tools for screening, treatment, and support; it has been deployed with promising results in behavioral health programs and primary care settings. Broader adoption of improved suicide prevention care may be an effective strategy for reducing deaths by suicide.

Suicide Trends Among and Within Urbanization Levels by Sex, Race/Ethnicity, Age Group, and Mechanism of Death - United States, 2001-2015

PROBLEM/CONDITION

Suicide is a public health problem and one of the top 10 leading causes of death in the United States. Substantial geographic variations in suicide rates exist, with suicides in rural areas occurring at much higher rates than those occurring in more urban areas. Understanding demographic trends and mechanisms of death among and within urbanization levels is important to developing and targeting future prevention efforts.

REPORTING PERIOD

2001-2015.

DESCRIPTION OF SYSTEM

Mortality data from the National Vital Statistics System (NVSS) include demographic, geographic, and cause of death information derived from death certificates filed in the 50 states and the District of Columbia. NVSS was used to identify suicide deaths, defined by International Classification of Diseases, 10th Revision (ICD-10) underlying cause of death codes X60-X84, Y87.0, and U03. This report examines annual county level trends in suicide rates during 2001-2015 among and within urbanization levels by select demographics and mechanisms of death. Counties were collapsed into three urbanization levels using the 2006 National Center for Health Statistics classification scheme.

RESULTS

Suicide rates increased across the three urbanization levels, with higher rates in nonmetropolitan/rural counties than in medium/small or large metropolitan counties. Each urbanization level experienced substantial annual rate changes at different times during the study period. Across urbanization levels, suicide rates were consistently highest for men and non-Hispanic American Indian/Alaska Natives compared with rates for women and other racial/ethnic groups; however, rates were highest for non-Hispanic whites in more metropolitan counties. Trends indicate that suicide rates for non-Hispanic blacks were lowest in nonmetropolitan/rural counties and highest in more urban counties. Increases in suicide rates occurred for all age groups across urbanization levels, with the highest rates for persons aged 35-64 years. For mechanism of death, greater increases in rates of suicide by firearms and hanging/suffocation occurred across all urbanization levels; rates of suicide by firearms in nonmetropolitan/rural counties were almost two times that of rates in larger metropolitan counties.

INTERPRETATION

Suicide rates in nonmetropolitan/rural counties are consistently higher than suicide rates in metropolitan counties. These trends also are observed by sex, race/ethnicity, age group, and mechanism of death.

PUBLIC HEALTH ACTION

Interventions to prevent suicides should be ongoing, particularly in rural areas. Comprehensive suicide prevention efforts might include leveraging protective factors and providing innovative prevention strategies that increase access to health care and mental health care in rural communities. In addition, distribution of socioeconomic factors varies in different communities and needs to be better understood in the context of suicide prevention.

Should compulsory admission to hospital be part of suicide prevention strategies?

The World Health Organization report Preventing Suicide: A Global Imperative provides governments with guidance for comprehensive suicide prevention strategies. However, it does not mention the role that compulsory admission to hospital of psychiatric patients should have in policies for suicide prevention. This was a missed opportunity for international discussion and guidance about a measure that, although widely used, is becoming increasingly controversial in light of the existing evidence and human rights norms.

The need for a culturally-tailored gatekeeper training intervention program in preventing suicide among Indigenous peoples: a systematic review

BACKGROUND

Suicide is a leading cause of death among Indigenous youth worldwide. The aim of this literature review was to determine the cultural appropriateness and identify evidence for the effectiveness of current gatekeeper suicide prevention training programs within the international Indigenous community.

METHOD

Using a systematic strategy, relevant databases and targeted resources were searched using the following terms: 'suicide', 'gatekeeper', 'training', 'suicide prevention training', 'suicide intervention training' and 'Indigenous'. Other internationally relevant descriptors for the keyword "Indigenous" (e.g. "Maori", "First Nations", "Native American", "Inuit", "Metis" and "Aboriginal") were also used.

RESULTS

Six articles, comprising five studies, met criteria for inclusion; two Australian, two from USA and one Canadian. While pre and post follow up studies reported positive outcomes, this was not confirmed in the single randomised controlled trial identified. However, the randomised controlled trial may have been underpowered and contained participants who were at higher risk of suicide pre-training.

CONCLUSION

Uncontrolled evidence suggests that gatekeeper training may be a promising suicide intervention in Indigenous communities but needs to be culturally tailored to the target population. Further RCT evidence is required.
