Suicide prevention in Hong Kong: pushing boundaries while building bridges.

Hong Kong is a natural laboratory for studying suicides-small geographic footprint, bustling economic activity, rapidly changing socio-demographic transitions, and cultural crossroads. Its qualities also intensify the challenges posed when seeking to prevent them. In this viewpoint, we showed the research and practices of suicide prevention efforts made by the Hong Kong Jockey Club Centre for Suicide Research and Prevention (CSRP), which provide the theoretical underpinning of suicide prevention and empirical evidence. CSRP adopted a multi-level public health approach (universal, selective and indicated), and has collaboratively designed, implemented, and evaluated numerous programs that have demonstrated effectiveness in suicide prevention and mental well-being promotion. The center serves as a hub and a catalyst for creating, identifying, deploying, and evaluating suicide prevention initiatives, which have the potential to reduce regional suicides rates when taken to scale and sustained.

Systematic Review of the Link Between Social Cognition and Suicidal Ideation and Behavior in People With Serious Mental Illness.

Background and Hypothesis: People with serious mental illness (SMI; psychotic and affective disorders with psychosis) are at an increased risk of suicide, yet there is limited research on the correlates of suicide in SMI. Social cognitive impairments are common among people with SMI and several studies have examined social cognition and suicidal ideation (SI) and behavior. This systematic review aims to evaluate the links between various domains of social cognition, SI, and suicidal behavior in SMI. Study Design: Electronic databases (PubMed and PsycInfo) were searched through June 2023. Records obtained through this search (N = 618) were screened by 2 independent reviewers according to inclusion criteria. Relevant data were extracted, and study quality was assessed. Study Results: Studies (N = 16) from 12 independent samples were included in the systematic review (N = 2631, sample sizes ranged from N = 20 to N = 593). Assessments of social cognition and SI and behavior varied widely between studies. Broadly, effects were mixed. Better emotion recognition of negative affect was linked to SI and a history of suicide attempts, though there is little consistent evidence for the relationship of emotion recognition and SI or behavior. On the other hand, better theory of mind ability was linked to SI and a history of suicide attempts. Furthermore, negative attributional bias was linked to current SI, but not a history of SI or attempt. Conclusions: This review suggests mixed associations between social cognition, SI, and behavior in SMI. Future research should evaluate additional mediators and moderators of social cognition and suicide, employing prospective designs.

Understanding Risk Factors for Suicide Among Older People in Rural China: A Systematic Review.

Background and Objectives: In China, rural older adults face a significantly heightened risk of suicide. However, there has been no comprehensive review of the literature examining the risk factors associated with suicide among older people in rural China. Therefore, a comprehensive understanding of risk factors for this phenomenon among rural older people must be gained. We conducted a systematic literature review on risk factors for suicide among older people in rural China. Research Design and Methods: Seven English electronic databases (PubMed, EMBASE, PsycINFO, Cochrane, CINAHL, ScienceDirect, and Web of Science) and 3 Chinese electronic databases (CNKI, CQVIP, and Wanfang) were searched for peer-reviewed articles published in English or Chinese, from inception to July 25, 2022. For data collection, scientific strategies were used for searching and selecting literature within the electronic databases. The collected data were then synthesized using the thematic analysis method. The study was conducted under PRISMA 2020 guidelines. Results: The final analysis included 16 studies. The identified risk factors were categorized under 6 themes: navigating the challenges of illness, unmet basic needs, experiencing abuse from children, feelings of loneliness, negative life events, and altruistic motivation to benefit children. Discussion and Implications: Multiple factors affect suicide among older people in rural China. This invaluable information can be used to develop targeted prevention strategies particularly relevant to this age group.

Relationship Between Severity and Length of Exposure to COVID-19 Parameters and Resulting Government Responses and the Suicide Crisis Syndrome (SCS).

OBJECTIVE: The COVID-19 pandemic has had a globally devastating psychosocial impact. A detailed understanding of the mental health implications of this worldwide crisis is critical for successful mitigation of and preparation for future pandemics. Using a large international sample, we investigated in the present study the relationship between multiple COVID-19 parameters (both disease characteristics and government responses) and the incidence of the suicide crisis syndrome (SCS), an acute negative affect state associated with near-term suicidal behavior. METHODS: Data were collected from 5528 adults across 10 different countries in an anonymous web-based survey between June 2020 and January 2021. RESULTS: Individuals scoring above the SCS cut-off lived in countries with higher peak daily cases and deaths during the first wave of the pandemic. Additionally, the longer participants had been exposed to markers of pandemic severity (eg, lockdowns), the more likely they were to screen positive for the SCS. Findings reflected both country-to-country comparisons and individual variation within the pooled sample. CONCLUSION: Both the pandemic itself and the government interventions utilized to contain the spread appear to be associated with suicide risk. Public policy should include efforts to mitigate the mental health impact of current and future global disasters.

Risk factors for suicide reattempt: a systematic review and meta-analysis.

BACKGROUND: Suicide is one of the main external causes of death worldwide. People who have already attempted suicide are at high risk of new suicidal behavior. However, there is a lack of information on the risk factors that facilitate the appearance of reattempts. The aim of this study was to calculate the risk of suicide reattempt in the presence of suicidal history and psychosocial risk factors and to estimate the effect of each individual risk factor. METHODS: This systematic review and meta-analysis were conducted following the PRISMA-2020 guidelines. Studies on suicide reattempt that measured risk factors were searched from inception to 2022. The risk factors studied were those directly related to suicide history: history of suicide prior to the index attempt, and those that mediate the transition from suicidal ideation to attempt (alcohol or drug misuse, impulsivity, trauma, and non-suicidal self-injury). RESULTS: The initial search resulted in 11 905 articles. Of these, 34 articles were selected for this meta-analysis, jointly presenting 52 different effect sizes. The pooled effect size across the risk factors was significant (OR 2.16). Reattempt risk may be increased in presence of any of the following risk factors: previous history, active suicidal ideation, trauma, alcohol misuse, and drug misuse. However, impulsivity, and non-suicidal self-injury did not show a significant effect on reattempt. CONCLUSION: Most of the risk factors traditionally associated with suicide are also relevant when talking about suicide reattempts. Knowing the traits that define reattempters can help develop better preventive and intervention plans.

Impact of COVID-19 restrictions on self-poisoning behaviour with mild analgesics in Danish youth.

BACKGROUND: The COVID-19 pandemic prompted the implementation of precautions to contain the disease, including lockdowns and social isolation. Previous studies have investigated suicide rates among children and adolescents during the pandemic and have found varying results. We speculated how the two lockdowns influenced suicidal behaviour in children and adolescents in Denmark. OBJECTIVE: This study aimed to investigate the effect of lockdowns during the COVID-19 pandemic on suicide attempts, as measured by the incidence rate in all self-poisonings with mild analgesics among children and adolescents. METHODS: This national Danish registry-based study on children and adolescents used Poisson regression and interrupted time series analysis to examine the incidence rates and trends of self-poisonings with mild analgesics from 2019 to mid-2021. RESULTS: For the period of this study, 1655 self-poisonings were registered. During the first lockdown, there was a slight, not statistically significant, decrease in self-poisoning rates (incidence rate ratio [IRR]) 0.98) compared to no lockdown. During the second lockdown, there was a significant increase in self-poisonings for the whole Danish population (IRR 1.85) with girls being slightly higher at risk (IRR 1.87). Being a girl or between the ages of 13-17 years old were risk factors for self-poisoning. CONCLUSION: These findings indicate that the restrictions enforced during the second lockdown greatly impacted youth mental health, especially girls, leading to an 85% increase in self-poisonings. We hope for increased awareness of mental health in children and adolescents during possible future lockdowns.

Mechanical trauma in children and adolescents in Berlin.

Management of severe pediatric trauma remains challenging. Injury patterns vary according to patient age and trauma mechanism. This study analyzes trauma mechanisms in deceased pediatric patients. Fatal pediatric trauma cases aged 0-18 years who underwent forensic autopsy in the Federal State of Berlin, Germany, between 2008 until 2018 were enrolled in this retrospective study. Autopsy protocols were analyzed regarding demographic characteristics, trauma mechanisms, injury patterns, resuscitation measures, survival times as well as place, and cause of death. 71 patients (73% male) were included. Traffic accidents (40%) were the leading cause of trauma, followed by falls from height > 3 m (32%), railway accidents (13%), third party violence (11%) and other causes (4%). While children under 14 years of age died mostly due to traumatic brain injury (59%), polytrauma was the leading cause of death in patients > 14 years (55%). Other causes of death were hemorrhage (9%), thoracic trauma (1%) or other (10%). A suicidal background was proven in 24%. In the age group of > 14 years, 40% of all mortalities were suicides. Cardiopulmonary resuscitation was carried out in 39% of all patients. 42% of the patients died at the scene. Children between 0 and 14 years of age died most frequently from traumatic brain injury. In adolescents between 14 and 18 years of age, polytrauma was mostly the cause of death with a high coincidence of suicidal deaths. The frequency of fatal traffic accidents and suicides shows the need to improve accident and suicide prevention for children and adolescents.

The prevalence of mental illness in young people in custody over time: a comparison of three surveys in New South Wales.

Few studies have examined the prevalence of mental illness in young people over time within the same jurisdiction. In the current study, we compared data from three large surveys of youth in custody in New South Wales, conducted in 2003, 2009 and 2015. We examined rates of mental illness, self-harm and suicidal behaviours, substance use and childhood trauma and found little consistent change over time, though some fluctuations were observed regarding certain mental illnesses and substance use. We also descriptively compared findings with observed rates for the general population and found that young people in custody showed higher levels of all examined variables. In sum, these data suggest little improvement in the well-being of young people in custody in New South Wales over time. Better identification and treatment of these issues are vital if young people are to be prevented from becoming enmeshed in the criminal justice system.

Preventable suicides involving medicines: A systematic case series of coroners' reports in England and Wales.

Background: In England and Wales coroners have a duty to write a report, called a Prevention of Future Deaths report or PFD, when they believe that actions should be taken to prevent future deaths. Coroners send PFDs to individuals and organisations who are required to respond within 56 days. Despite the increase in mental health concerns and growing use of medicines, deaths reported by coroners that have involved medicine-related suicides had not yet been explored. Therefore, this study aimed to systematically assess coroners' PFD reports involving suicides in which a medicine caused or contributed to the death to identify lessons for suicide prevention. Methods: Using the Preventable Deaths Tracker database (https://preventabledeathstracker.net/), 3037 coroners' PFD reports in England and Wales were screened for eligibility between July 2013 and December 2019. Reports were included if they involved suicide or intentional self-harm and prescribed or over-the-counter medication; illicit drugs were excluded. Following data extraction, descriptive statistics, document and content analysis were performed to assess coroners' concerns and the recipients of reports. Results: There were 734 suicide-related coroner reports, with 100 (14%) reporting a medicine. Opioids (40%) were the most common class involved, followed by antidepressants (30%). There was wide geographical variation in the writing of reports; coroners in Manchester wrote the most (18%). Coroners expressed 237 concerns; the most common were procedural inadequacies (14%, n = 32), inadequate documentation and communication (10%, n = 22), and inappropriate prescription access (9%, n = 21). 203 recipients received the PFDs, with most sent to NHS trusts (31%), clinical commissioning groups (10%), and general practices (10%), of which only 58% responded to the coroner. Conclusions: One in four coroner reports in England and Wales involved suicides, with one in seven suicide-related deaths involving a medicine. Concerns raised by coroners highlighted gaps in care that require action from the Government, health services, and prescribers to aid suicide prevention. Coroner reports should be routinely used and monitored to inform public health policy, disseminated nationally, and responses to coroners should be transparently enforced so that actions are taken to prevent future suicides.

Psychological pain and sociodemographic factors classified suicide attempt and non-suicidal self-injury in adolescents.

This study aimed to utilize machine learning to explore the psychological similarities and differences between suicide attempt (SA) and non-suicidal self-injury (NSSI), with a particular focus on the role of psychological pain. A total of 2385 middle school students were recruited using cluster sampling. The random forest algorithm was used with 25 predictors to develop classification models of SA and NSSI, respectively, and to estimate the importance scores of each predictor. Based on these scores and related theories, shared risk factors (control feature set) and distinct risk factors (distinction feature set) were selected and tested to distinguish between NSSI and SA. The machine learning algorithm exhibited fair to good performance in classifying SA history [Area Under Curves (AUCs): 0.65-0.87] and poor performance in classifying NSSI history (AUC: 0.61-0.68). The distinction feature set comprised pain avoidance, family togetherness, and deviant peer affiliation, while the control feature set included pain arousal, painful feelings, and crisis events. The distinction feature set slightly but stably outperformed the control feature set in classifying SA from NSSI. The three-dimensional psychological pain model, especially pain avoidance, might play a dominant role in understanding the similarities and differences between SA and NSSI.

Perceptions of key stakeholders on peer led strength building program for suicide prevention among young adolescents: A qualitative study from Karnataka, India.

Context: Adolescent suicides are a significant public health concern in India and understanding the intersecting perspectives becomes imperative for the prevention of various mental health concerns. Aim: Assessing perceptions of various key stakeholders, that is, mental health experts, school and college teachers, and District Mental Health Program staff about peer-led strength building programs for suicide prevention. Settings and Design: A cross-sectional qualitative design using two Focus Group Discussions (FGDs) with mental health experts and teachers and one FGD with DMHP staff was conducted. The sample comprised 45 participants from Bengaluru urban district. Materials and Methods: The data were analyzed manually by the method of direct content analysis, and themes were determined using existing literature. Results: The teachers and the DMHP highlighted the need for an intensive training program/module that is necessary to be developed in order to train the peer leaders first. The mental health experts opined that creating a network will help in easy identification of the cases and appropriate treatment could be provided without delays. Conclusions: This study indicated that suicide is a preventable public health emergency and inaccessibility to existing as well as proper support systems was perceived as a major concern. Therefore, peer-led programs are beneficial in steering and improving help seeking behavior in suicidal adolescents.

Criminal Defense Attorneys and Client Suicide: Survey and Recommendations From Washington State.

The connection between suicide and incarceration is well documented, in particular after recent arrest. Criminal defense attorneys may be one of the few people in meaningful contact with this population, and lawyers have a unique window into their clients' well-being. In this Viewpoint, we explore the experiences of attorneys who work with clients with suicidal thoughts and behaviors. We developed and administered a survey to criminal defense attorneys in the State of Washington, ascertaining their experiences with client suicide. A total of 44 responses were collected, with over 95% of respondents having been concerned about a client's risk for suicide. We conclude that client suicide widely impacts criminal defense attorneys, and lawyers' role with justice-involved clients uniquely positions them to be a potential asset in suicide prevention efforts.

Suicide-preventive compulsory admission is not a proportionate measure - time for clinicians to recognise the associated risks.

Suicide is considered a global public health issue and compulsory admission is a commonly used measure to prevent suicide. However, the practice has been criticised since several studies indicate that the measure lacks empirical support and may even increase suicide risk. This paper investigates whether the practice has enough empirical support to be considered proportionate. To that end, arguments supporting compulsory admission as a suicide-preventive measure for most suicidal patients are scrutinized. The ethical point of departure is that the expected benefits of compulsory admission should outweigh the potential harms of the measure to be proportionate and defensible. It is concluded that, for most suicidal patients, suicide-preventive compulsory admission cannot be presumed to be a proportionate measure. To be so, the expected medical benefits of the measure should be greater than the potential increase in suicide risk and other harms that compulsory admission could entail. Instead of using compulsory admission as a suicide-preventive measure, extra safety measures may be needed during and after compulsory admission to prevent the risk of hospitalisation-induced suicide.

Identifying suicide attempter in major depressive disorder through machine learning: the importance of pain avoidance, event-related potential features of affective processing.

How to achieve a high-precision suicide attempt classifier based on the three-dimensional psychological pain model is a valuable issue in suicide research. The aim of the present study is to explore the importance of pain avoidance and its related neural features in suicide attempt classification models among patients with major depressive disorder. By recursive feature elimination with cross-validation and support-vector-machine algorithms, scores from the measurements and the task-based EEG signals were chosen to achieve a suicide attempt classification model. In the multimodal suicide attempt classifier with an accuracy of 83.91% and an area under the curve of 0.90, pain avoidance ranked as the top one in the optimal feature set. Theta (reward positive feedback minus neutral positive feedback) was the shared neural representation ranking as the top one of event-related potential features in pain avoidance and suicide attempt classifiers. In conclusion, the suicide attempt classifier based on pain avoidance and its related affective processing neural features has excellent accuracy among patients with major depressive disorder. Pain avoidance is a stable and strong indicator for identifying suicide risks in both traditional analyses and machine-learning approaches. A novel methodology is needed to clarify the relationship between cognitive and affective processing evoked by punishment stimuli and pain avoidance.

Profiles of suicide attempted in children and adolescents.

OBJECTIVE: Suicide attempt (SA) is the strongest predictive variable for completed suicide. The Department of Cauca in Colombia has an SA rate higher than the national average, but the factors are unknown. The objective was to identify the profiles of SA in children and adolescents of Cauca. METHODS: Cross-sectional study, which included all SA (Event-356) records from the SIVIGILA platform in children under 18 years of age between 2016 and 2019. The authors described the variables and multiple correspondence analysis with the Burt method, according to the completeness of the data to establish the possible SA profiles using STATA 15.1, and R. The Ethics Committee at Universidad del Cauca approved it. RESULTS: The study found 977 SA during this period, 72.4% female, 97.1% adolescent, 74.4% mestizo, 19.3% indigenous, 45.3% resided in municipalities exposed to the armed conflict, 32.3% expressed ideation and previous attempts, and 15.5% prior attempts. The MCA included 810 SA and identified three profiles: "Classic", which had mestizo adolescents with a history of prior SA, mental illness, or psychoactive substance use problems; "Related to the armed conflict", which included female adolescents with a first SA and residents in municipalities exposed to the armed conflict; "Ethnic" represented by male indigenous, with housing in a rural area. CONCLUSION: The SA profiles found in Cauca were "Classic", "Related to the armed conflict", and "Ethnic"; these can be considered to implement prevention strategies from a cross-cultural, mental health, and gender perspective, with the presence of the state in the territories.

The influence of psychotherapy on individuals who have attempted suicide: A systematic review and meta-analysis.

INTRODUCTION: Suicide is a serious global public health issue, and a history of attempted suicide is the most critical indicator of suicide risk. There are limited studies on the effectiveness of psychotherapy in individuals who have attempted suicide, and other outcome measures related to suicide risk in suicide attempts have not been explored. AIM/QUESTION: This study aimed to systematically review and perform a meta-analysis of the effectiveness of psychotherapy on individuals who have attempted suicide. METHODS: This study conducted a comprehensive literature search of five major databases (PubMed, EMBASE, Cochrane, Web of Science, and Ovid). The protocol for this study is registered with PROSPERO (CRD42023464401) and follows the PRISMA guidelines. RESULTS: This meta-analysis included a total of 34 trials from 32 literature sources. The study involved a total of 6600 participants. The results showed that psychotherapy had a positive effect on reducing the suicidal tendencies of individuals who have attempted suicide and effectively reduced the number of repeated suicide attempts as well as the levels of suicidal ideation, depression, anxiety and hopelessness. IMPLICATIONS FOR PRACTICE: This study concludes that psychotherapy is effective in reducing the suicidal tendencies of individuals who have attempted suicide. Psychological therapy for individuals who have attempted suicide are crucial in preventing future suicidal behaviours.

A PRISMA Scoping Review to Explore Interventions to Prevent Firearm-Related Injury and Suicide in Older Adults.

OBJECTIVES: This scoping review aims to examine existing research into firearm safety interventions designed to prevent firearm injury and suicide in older adults. METHODS: Select databases were searched in 5/2023. Included articles involved an/a 1. aim to develop or investigate firearm safety interventions, 2. focus on adults 50 years and older, and 3. primary analysis. RESULTS: The search yielded 10 articles which primarily focused on firearm safety counseling with older adults with suicide risk or emerging impairment. The review found that older adults may be open to receiving firearm safety counseling but that providers feel ill-equipped to have these conversations and to reliably identify suicide risk. Two studies presented promising data on the impact and acceptability of training providers in a firearm safety intervention. The review also identified the importance of building trust between older patients and providers to have helpful discussions regarding firearms, and highlighted specific approaches that facilitate openness to participate in these exchanges. CONCLUSIONS: Further research into adapting interventions to meet the clinical needs of older adults and treatment efficacy trials is necessary. CLINICAL IMPLICATIONS: Training healthcare providers to conduct firearm safety interventions with older adults may be an acceptable and impactful avenue to prevent suicide.

Practical strategies for care of individuals impacted by suicide in the emergency department: A narrative review.

Introduction Suicide is among the leading causes of death and nurses care for survivors of suicide at many points in their grief journey. Every individual who dies by suicide leaves behind multiple affected survivors and how they are cared for immediately following the suicide influences how they cope with the death. The purpose of this article is to make recommendations for the care of survivors of suicide loss in the emergency department. METHODS: A narrative review of the current literature was conducted using the databases CINAHL and ProQuest. Articles focused on survivors of suicide loss and their care in the immediate period after the death were utilized. RESULTS: Four hundred and twenty-nine articles were found. Applying established inclusion and exclusion criteria and quality assessment using the SANSA guideline, 29 were included in the review. DISCUSSION: Three themes were identified: 1. Risks for suicide in survivors of suicide loss; 2. Interventions in the immediate period after suicide loss; and 3. Active suicide postvention as suicide prevention. Emergency department nurses need to have the ability to readily assess and recognize the survivors of suicide loss who are at higher risk for complicated grieving, and providing rapid and immediate services and resources will help promote coping and positive mental health outcomes in survivors.

A scientometric analysis and visualisation of elderly suicide research from 1951 to 2022.

BACKGROUND: There are still many gaps in both national and international literature on elderly suicide. This study aimed to identify the most influential journals in elderly suicide, the countries and authors that contribute the most to the field, and the trends in the field. MATERIAL AND METHODS: Studies published on elderly suicide between 1951 and 2022 were retrieved utilising the Web of Science Core Collection. Co-authorship analysis of countries and authors, as well as co-occurrence analysis of keywords, were conducted using VOSviewer 1.6.18. RESULTS: There were 2864 articles retrieved, including 95 countries, 889 academic journals, 9162 authors and 4160 keywords. The number of publications in this field has significantly increased after the 2000s, and the United States is the most productive country (996). The most prolific author is Yeates Conwell, while the journal with the highest number of publications in this field is the International Journal of Geriatric Psychiatry. Other than 'suicide' and 'elderly', the most trending keywords are 'depression', 'primary care', 'treatment', 'antidepressant', 'loneliness', 'quality of life' and 'COVID-19'. CONCLUSION: There has been an increase in both the thematic diversity and quantity of studies on elderly suicide over time. However, these publications predominantly originate from socioeconomically affluent countries with relatively low suicide rates. While the increasing numbers of publications from developing countries in recent years are promising, there is a greater need for publications from countries with lower socioeconomic status for the prevention or intervention of elderly suicides.
