Immediate and long-term health impact of exposure to gas-mining induced earthquakes and related environmental stressors.

BACKGROUND: Little is known about the public health impact of chronic exposure to physical and social stressors in the human environment. Objective of this study was to investigate the immediate and long-term health effects of living in an environment with gas-mining induced earthquakes and related stressors in the Netherlands. METHODS: Data on psychological, somatic and social problems recorded routinely in electronic health records by general practitioners during a 6-year period (2010-2015) were combined with socioeconomic status and seismicity data. To assess immediate health effects of exposure to ML≥1.5 earthquakes, relative risk ratios were calculated for patients in the week of an earthquake and the week afterwards, and compared to the week before the earthquake. To analyse long-term health effects, relative risks of different groups, adjusted for age, sex and socioeconomic status, were computed per year and compared. RESULTS: Apart from an increase in suicidality, few immediate health changes were found in an earthquake week or week afterwards. Generally, the prevalence of health problems was higher in the mining province in the first years, but dropped to levels equal to or even below the control group in subsequent years, with lower relative risks observed in more frequently exposed patients. CONCLUSIONS: From a public health perspective, the findings are fascinating. Contrary to our expectation, health problems presented in general practice in the earthquake province decreased during the study period. More frequently exposed populations reported fewer health issues to general practitioners, which might point at health adaptation to chronic exposure to stressors.

Ethical concerns in suicide research: thematic analysis of the views of human research ethics committees in Australia.

BACKGROUND: Suicide research aims to contribute to a better understanding of suicidal behaviour and its prevention. However, there are many ethical challenges in this research field, for example, regarding consent and potential risks to participants. While studies to-date have focused on the perspective of the researchers, this study aimed to investigate the views and experiences of members of Human Research Ethics Committees (HRECs) in dealing with suicide-related study applications. METHODS: This qualitative study entailed a thematic analysis using an inductive approach. We conducted semi-structured interviews with a purposive sample (N = 15) of HREC Chairs or their delegates from Australian research-intensive universities. The interview guide included questions regarding the ethical concerns and challenges in suicide-related research raised by HREC members, how they dealt with those challenges and what advice they could give to researchers. RESULTS: The analysis identified four main themes: (1) HREC members' experiences of reviewing suicide-related study applications, (2) HREC members' perceptions of suicide, suicide research, and study participants, (3) Complexity in HREC members' decision-making processes, and (4) HREC members' relationships with researchers. CONCLUSIONS: Reliance on ethical guidelines and dialogue with researchers are crucial in the assessment of suicide-related study applications. Both researchers and HREC members may benefit from guidance and resources on how to conduct ethically sound suicide-related studies. Developing working relationships will be likely to help HRECs to facilitate high quality, ethical suicide-related research and researchers to conduct such research.

The vulnerability paradox in global mental health and its applicability to suicide.

BACKGROUND: Previous research has identified a vulnerability paradox in global mental health: contrary to positive associations at the individual level, lower vulnerability at the country level is accompanied by a higher prevalence in a variety of mental health problems in national populations. However, the validity of the paradox has been challenged, specifically for bias from modest sample sizes and reliance on a survey methodology not designed for cross-national comparisons.AimsTo verify whether the paradox applies to suicide, using data from a sizable country sample and an entirely different data source. METHOD: We combined data from the World Health Organization 2014 suicide report and the country vulnerability index from the 2016 World Risk Report. Suicide was predicted in different steps based on gender, vulnerability and their interaction, World Bank income categories, and suicide data quality. RESULTS: A negative association between country vulnerability and suicide prevalence in both women and men was found. Suicide rates were higher for men, regardless of country vulnerability. The model predicting suicide in 96 countries based on gender, vulnerability, income and data quality had the best goodness-of-fit compared with other models. The vulnerability paradox is not accounted for by income or data quality, and exists across and within income categories. CONCLUSIONS: The study underscores the relevance of country-level factors in the study of mental health problems. The lower mental disorder prevalence in more vulnerable countries implies that living in such countries fosters protective factors that more than compensate for the limitations in professional healthcare capacity.Declaration of interestNone.

Effectiveness of interventions for people bereaved through suicide: a systematic review of controlled studies of grief, psychosocial and suicide-related outcomes.

BACKGROUND: Suicide bereavement is a risk factor for adverse outcomes related to grief, social functioning, mental health and suicidal behaviour. Consequently, suicide bereavement support (i.e., postvention) has been identified as an important suicide prevention strategy. However, little is known about its effectiveness. To redress this gap, this review aimed to assess the evidence of effectiveness of interventions for people bereaved by suicide, and appraise the quality of the research in this field. METHODS: We conducted a systematic review according to PRISMA guidelines. Searches of peer-reviewed literature in Medline, PsycINFO, Embase and EBM Reviews identified 12 papers reporting on 11 relevant studies conducted between 1984 and 2018. RESULTS: Across studies, there was a wide variety of intervention modalities, study populations, control groups, and grief, psychosocial and suicide-related outcome measures. Overall, the quality of studies was weak. While there was some evidence of the effectiveness of interventions for uncomplicated grief, evidence of the effectiveness of complicated grief interventions was lacking. Based on this scant evidence, interventions which seem to show promise include supportive, therapeutic and educational approaches, involve the social environment of the bereaved, and comprise a series of sessions led by trained facilitators. CONCLUSIONS: There is a clear need for additional methodologically sound studies in this area. Specifically, selection procedures, sample sizes, randomization, and the use of appropriate measures are crucial. As people bereaved by suicide are at-risk of adverse grief, mental ill-health and suicidal behaviour, further research across the life-span is essential to prevent grief and mental health ramifications.

Using a television documentary to prevent suicide in men and boys.

OBJECTIVES: We investigated whether a documentary about masculinity and suicidality ( Man Up) could raise males' awareness of societal pressures to conform to masculine norms and influence their likelihood of connecting with their male friends and seeking help. METHODS: We conducted a repeat cross-sectional survey, posting versions of the survey online before and after Man Up was screened. RESULTS: 1287 male respondents completed the survey; 476 completed the pre-screening survey, 811 the post-screening survey (192 had not viewed Man Up, 619 had). Those who had viewed Man Up were more likely to desire closer relationships with their male friends than those who had not, and had greater awareness of societal pressures on males, but were no more likely to seek help. Almost all respondents who saw Man Up indicated they would recommend it to others, and most said it changed the way they thought about the term 'man up'. They indicated they would be likely to undertake a number of adaptive actions following the show, and provided overwhelmingly positive feedback. CONCLUSIONS: Man Up appeared to effectively address factors that place males at heightened risk of suicide.

Improving access to primary mental health care for Australian children.

OBJECTIVE: This study examines the uptake by children aged predominantly 0-11 years of an Australian primary mental health service - the Access to Allied Psychological Services programme - which began in 2001. In particular, it considers access to, and use of, the child component of Access to Allied Psychological Services, the Child Mental Health Service, introduced in 2010. METHOD: Using routinely collected programme data from a national minimum dataset and regional population data, we conducted descriptive and regression analysis to examine programme uptake, predictors of service reach and consumer- and treatment-based characteristics of service. RESULTS: Between 2003 and 2013, 18,631 referrals for children were made and 75,178 sessions were scheduled via Access to Allied Psychological Services, over 50% of which were via the Child Mental Health Service in its first 3 years of operation. The rate of referrals for children to the Child Mental Health Service was associated with the rate of Access to Allied Psychological Services referrals for consumers aged 12+ years. CONCLUSIONS: The Child Mental Health Service has increased services provided within the Access to Allied Psychological Services programme for children with emotional and behavioural issues and their families, and is potentially filling a service gap in the area of prevention and early intervention for children who have significant levels of need but are unable to access other mental health services. Our findings are policy-relevant for other developed countries with a similar primary mental health care system that are considering means of improving service access by children.

Improving access to primary mental healthcare for Indigenous Australians.

OBJECTIVE: To examine the uptake, population reach and outcomes of primary mental healthcare services provided to Indigenous Australians via the Access to Allied Psychological Services (ATAPS) program between 2003 and 2013, with particular reference to enhanced Indigenous ATAPS services introduced from 2010. METHOD: Utilising ATAPS program data from a national minimum data set and comparative population data, we conducted descriptive analyses, regression analyses and t-tests to examine the uptake of ATAPS services, provider agency level predictors of service reach, and preliminary outcome data on consumer level outcomes. RESULTS: Between 2003 and 2013, 15,450 Indigenous client referrals were made that resulted in 55,134 ATAPS sessions. National Indigenous service volume more than doubled between 2010 and 2012, following the introduction of enhanced Indigenous ATAPS services. Non-Indigenous ATAPS service volume of primary care agencies was uniquely predictive of Indigenous service reach. Preliminary analysis of limited consumer outcome data indicated positive treatment gains and the need to enhance future outcome data collection. CONCLUSIONS: Concerted national efforts to enhance mainstream primary mental healthcare programs can result in significant gains in access to mental healthcare for Indigenous populations.

Why did Divisions of General Practice implement some Access to Allied Psychological Services mental health initiatives and not others?

OBJECTIVE: The Access to Allied Psychological Services (ATAPS) programs implemented through Divisions of General Practice (now Medicare Locals) enables general practitioners (GPs) to refer consumers with high-prevalence mental disorders for up to 12 individual and/or group sessions of evidence-based mental health care. The great strength of ATAPS is its ability to target vulnerable and hard-to-reach populations. Several initiatives have been introduced that focus on particular at-risk populations. This study aimed to determine the factors that had influenced Divisions' decisions to implement the various Tier 2 initiatives. METHODS: An online survey was sent to all Divisions. The survey contained mostly multiple choice questions and sought to determine which factors had influenced their decision-making. RESULTS: The most common factors influencing the decision to implement an initiative were the perception of local need and whether there was an existing service model that made it easier to add in new programs. The most commonly cited factors for not implementing were related to resources and administrative capacity. CONCLUSIONS: This research provides valuable insights into the issues that primary care organisations face when implementing new programs; the lessons learnt here could be useful when considering the implementation of other new primary care programs.

Suicide prevention during disasters and public health emergencies: a systematic review.

Background: Disasters and public health emergencies increasingly affect populations around the world, posing significant wide-ranging challenges for societies as well as for effective public health and suicide prevention. Intervention research is essential to inform evidence-based responses. Yet, despite evident public concern and growing research interest in heightened suicide risks and impacts, little is known about effective suicide prevention interventions in these contexts. We conducted a systematic review to examine the outcomes of suicide prevention strategies implemented in disasters and public health emergencies. Methods: We searched five databases (Medline, Embase, PsycINFO, Web of Science, PTSDpubs) from inception to December 2022 for peer-reviewed quantitative studies that reported relevant intervention outcomes (changes in the frequency of suicide, suicide attempts, self-harm) for populations affected by disasters and public health emergencies. We assessed the quality of eligible studies using the Quality Assessment Tool for Quantitative Studies, and distilled review findings through narrative synthesis. The study protocol was registered with PROSPERO (CRD42021276195). Results: Ten eligible and mostly observational studies were included in this review, which examined a range of universal, selective, and indicated interventions. Three of five studies of interventions in public health emergencies indicated the potential effectiveness and buffering effects of generic disaster related mental health support, access to urban parks, as well as the beneficial role of video-enabled tablets in facilitating treatment access and outcomes. Similarly, three of five studies of interventions in disaster contexts provided evidence of the beneficial role of universal economic security measures, national gun laws and buy back schemes, and volunteer-delivered mental health support. Overall, four of six studies with favorable outcomes examined interventions specifically deployed in disaster or public health emergency contexts, whereas two studies examined ongoing existing interventions. Three studies, respectively, of suicide prevention focused interventions or generic interventions reported favorable outcomes. The quality of included studies was variable, with two studies being rated as 'strong', four studies rated as 'moderate', and four studies rated as 'weak'. Conclusion: Notwithstanding the limited scope and variable quality of published evidence, our review findings highlight the breadth of interventions that have been applied in such contexts with some success. There is a need for further research on effective interventions and intervention adaptations to inform evidence-based suicide prevention responses to disasters and public health emergencies.

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.

Suicide prevention: evaluation of a pilot intervention in a primary care context.

BACKGROUND: From July 2008 to June 2011, 19 Australian Divisions of General Practice piloted specialist services for consumers at risk of suicide within a broader primary mental health program. General practitioners and other mental health staff referred suicidal consumers to specially trained mental health professionals for intensive, time-limited care. AIMS: To report the findings from an evaluation of the pilot. METHOD: Data sources included a purpose-designed minimum data set, which collated consumer-level and session-level data, and a series of structured telephone interviews conducted with Divisional project officers, referrers and mental health professionals. RESULTS: There were 2312 referrals to the pilot; 2070 individuals took up the service. The pilot reached people who may not otherwise have had access to psychological care; over half of those who received services were on low incomes and about one-third had not previously accessed mental health care. Project officers, referrers and mental health professionals were all positive about the pilot and commented that it was meeting a previously unmet need. Consumers appeared to benefit, showing significant improvements in outcomes. CONCLUSION: This evaluation provides supportive evidence for the effectiveness of a suicide prevention intervention delivered by specially trained mental health professionals in a primary mental health environment.

Innovations in primary mental healthcare.

OBJECTIVE: We review the evidence on innovations in Tier 2 of the Access to Allied Psychological Services (ATAPS) program, which is designed to facilitate the provision of primary mental healthcare to hard-to-reach and at-risk population groups (including women with perinatal depression, people at risk of self-harm or suicide, people experiencing or at risk of homelessness, people affected by the 2009 Victorian bushfires, people in remote locations, Aboriginal and Torres Strait Islanders and children with mental disorders) and the trialling of new modalities of service delivery (e.g. telephone-based or web-based CBT). The primary focus is on the uptake, outcomes and issues associated with the provision of ATAPS Tier 2. METHODS: Drawing on data from an ongoing national ATAPS evaluation, including a national minimum dataset, key informant interviews and surveys, the impact of ATAPS innovations is analysed and illustrated through program examples. RESULTS: ATAPS Tier 2 facilitates access to, uptake of and positive clinical outcomes from primary mental healthcare for population groups with particular needs, although it requires periods of time to implement locally. CONCLUSIONS: Relatively simple innovations in mental health program design can have important practical ramifications for service provision, extending program reach and improving mental health outcomes for target populations. What is known about the topic? It is recognised that innovative approaches are required to tailor mental health programs for hard-to-reach and at-risk population groups. Divisions of General Practice have implemented innovations in the Access to Allied Psychological Services (ATAPS) program for several years. What does this paper add? Drawing on data from an ongoing national ATAPS evaluation, this paper presents a systematic analysis of the uptake, outcomes and issues associated with provision of the innovative ATAPS program. What are the implications for practitioners? The findings highlight the benefits of introducing innovations in primary mental healthcare in terms of increased access to care and positive consumer outcomes. They also identify challenges to and facilitators of the implementation process, which can inform innovation efforts in other primary care contexts.

Ethical Issues to Consider in Designing Suicide Prevention Studies: An Expert Consensus Study.

AIM: Research is imperative to advance our understanding of suicidal behavior and its prevention. Suicide prevention research involves various ethical issues, many of which are not straightforward to address. Hence, suicide prevention researchers sometimes face particular issues when designing their research studies. This expert consensus study aimed to identify the most important ethical issues to consider when designing suicide prevention studies. METHODS: People with lived experience of suicide (N = 32) and suicide prevention researchers (N = 34) rated 80 statements on a 5-point Likert scale from "essential" to "should not be included." RESULTS: There was significant agreement between and within the two groups of participants with regard to the most highly rated statements. The most highly rated statements for both groups included the importance of the ethical principles of merit, integrity, justice, and beneficence. Additionally, lived experience participants placed emphasis on the support and care for researchers, and suicide prevention researchers placed emphasis on the risk management protocols and support services for participants. CONCLUSION: There was strong agreement between people with lived experience of suicide and suicide prevention researchers regarding what to consider when designing ethically sound suicide prevention research, including the importance of ethical principles and support for both participants and researchers.HIGHLIGHTSThere was strong agreement between people with lived experience of suicide and researchers.Researchers emphasized adherence to national guidelines.People with lived experience of suicide valued care for study participants and researchers.

Utilisation and application of implementation science in complex suicide prevention interventions: A systematic review.

OBJECTIVES: Little is known about how complex, multilevel, and multicomponent suicide prevention interventions work in real life settings. Understanding the methods used to systematically adopt, deliver, and sustain these interventions could ensure that they have the best chance of unfolding their full effect. This systematic review aimed to examine the application and extent of utilisation of implementation science in understanding and evaluating complex suicide prevention interventions. METHODS: The review adhered to updated PRISMA guidelines and was prospectively registered with PROSPERO (CRD42021247950). PubMed, CINAHL, PsycINFO, ProQuest, SCOPUS and CENTRAL were searched. All English-language records (1990-2022) with suicide and/or self-harm as the primary aims or targets of intervention were eligible. A forward citation search and a reference search further bolstered the search strategy. Interventions were considered complex if they consisted of three or more components and were implemented across two or more levels of socio-ecology or levels of prevention. RESULTS: One hundred thirty-nine records describing 19 complex interventions were identified. In 13 interventions, use of implementation science approaches, primarily process evaluations, was explicitly stated. However, extent of utilisation of implementation science approaches was found to be inconsistent and incomprehensive. LIMITATIONS: The inclusion criteria, along with a narrow definition of complex interventions may have limited our findings. CONCLUSION: Understanding the implementation of complex interventions is crucial for unlocking key questions about theory-practice knowledge translation. Inconsistent reporting and inadequate understanding of implementation processes can lead to loss of critical, experiential knowledge related to what works to prevent suicide in real world settings.

Evaluating the Effectiveness of Components of National Suicide Prevention Strategies.

Background: National suicide prevention strategies support development of suicide prevention activities and their evaluation. Aims: To describe components included in national suicide prevention strategies and analyze the potential contribution of individual components to reduce suicide rates. Method: We conducted a narrative review and statistical analysis of national suicide prevention strategies. The narrative review was based on a framework of 12 components and included 29 countries (14 lower middle-income countries [LMICs] and 15 high-income countries [HICs]) with a national suicide prevention strategy. The statistical analyses covered suicide mortality data for 24 countries with a national strategy (9 LMICs and 15 HICs). Results: The number of components adopted in national strategies ranged from 4 to 11, and training and education were included in 96.5% of strategies. Estimated period effects for total suicide rates in individual countries ranged from a significant decrease in the yearly suicide rate (RR = 0.80; 95% CI 0.69-0.93) to a significant increase (RR = 1.12; 95% CI 1.05-1.19). There were no changes in suicide mortality associated with individual components of national strategies. Limitations: The limitations of existing suicide mortality data apply to our study. Conclusion: Further detailed evaluations will help identify the specific contribution of individual components to the impact national strategies. Until then, countries should be encouraged to implement and evaluate comprehensive national suicide prevention strategies.

Modelling the cost-effectiveness of brief aftercare interventions following hospital-treated self-harm.

BACKGROUND: Prior self-harm represents the most significant risk factor for future self-harm or suicide. AIM: To evaluate the cost-effectiveness of a theoretical brief aftercare intervention (involving brief follow-up contact, care coordination and safety planning), following a hospital-treated self-harm episode, for reducing repeated self-harm within the Australian context. METHOD: We employed economic modelling techniques to undertake: (a) a return-on-investment analysis, which compared the cost-savings generated by the intervention with the overall cost of implementing the intervention; and (b) a cost-utility analysis, which compared the net costs of the intervention with health outcomes measured in quality-adjusted life years (QALYs). We considered cost offsets associated with hospital admission for self-harm and the cost of suicide over a period of 10 years in the base case analysis. Uncertainty and one-way sensitivity analyses were also conducted. RESULTS: The brief aftercare intervention resulted in net cost-savings of AUD$7.5 M (95% uncertainty interval: -56.2 M to 15.1 M) and was associated with a gain of 222 (95% uncertainty interval: 45 to 563) QALYs over a 10-year period. The estimated return-on-investment ratio for the intervention's modelled cost in relation to cost-savings was 1.58 (95% uncertainty interval: -0.17 to 5.33). Eighty-seven per cent of uncertainty iterations showed that the intervention could be considered cost-effective, either through cost-savings or with an acceptable cost-effectiveness ratio of 50 000 per QALY gained. The results remained robust across sensitivity analyses. CONCLUSIONS: A theoretical brief aftercare intervention is highly likely to be cost-effective for preventing suicide and self-harm among individuals with a history of self-harm.

Attributable risk of suicide for populations in Australia.

Objective: Each year approximately 3,000 Australians die by suicide. We estimated the population attributable risk for identified target populations to provide evidence on how much of the overall burden of suicide in the Australian population is experienced by each of them. Methods: We identified 17 demographic and clinical target populations at risk of suicide and calculated the population attributable fraction (PAF) using a single or pooled suicide risk and the proportional representation of each target population within Australia. Results: Large PAF estimates were found for men (52%, 95% confidence interval (CI) 51%-53%), people bereaved by suicide (35%, 95% CI 14%-64%), people with a mental health or behavioural condition (33%, 95%CI 17%-48%), people with a chronic physical condition (27%, 95%CI 18%-35%), adults aged 25-64 years (13%, 95%CI 12%-14%), LGB populations (9%, 95%CI 6%-13%), offenders (9%, 95%CI 8%-10%), and people employed in blue collar occupations (8%, 95%CI 4%-12%). Limitations: The PAF is limited by assumptions, namely, that risk factors are independent, and that the relationship between risk factors and outcomes are unidirectional and constant through time. Conclusions and implications for public health: Considerable reductions in the overall suicide rate in Australia may occur if risk factors are addressed in identified populations with large PAF estimates. These estimates should be considered as an adjunct to other important inputs into suicide prevention policy priorities.
