Suicide among emergency service workers: a retrospective mortality study of national coronial data, 2001-2017

BACKGROUND

Emergency service workers (ESW) are known to be at increased risk of mental disorders but population-level and longitudinal data regarding their risk of suicide are lacking.

METHOD

Suicide data for 2001-2017 were extracted from the Australian National Coronial Information Service (NCIS) for two occupational groups: ESW (ambulance personnel, fire-fighters and emergency workers, police officers) and individuals employed in all other occupations. Age-standardised suicide rates were calculated and risk of suicide compared using negative binomial regression modelling.

RESULTS

13 800 suicide cases were identified among employed adults (20-69 years) over the study period. The age-standardised suicide rate across all ESW was 14.3 per 100 000 (95% CI 11.0-17.7) compared to 9.8 per 100 000 (95% CI 9.6-9.9) for other occupations. Significant occupational differences in the method of suicide were identified (p < 0.001). There was no evidence for increased risk of suicide among ESW compared to other occupations once age, gender and year of death were accounted for (RR = 0.99, 95% CI 0.84-1.17; p = 0.95). In contrast, there was a trend for ambulance personnel to be at elevated risk of suicide (RR = 1.41, 95% CI 1.00-2.00, p = 0.053).

CONCLUSION

Whilst age-standardised suicide rates among ESW are higher than other occupations, emergency service work was not independently associated with an increased risk of suicide, with the exception of an observed trend in ambulance personnel. Despite an increased focus on ESW mental health and wellbeing over the last two decades, there was no evidence that rates of suicide among ESW are changing over time.

Child protection system involvement in children of incarcerated mothers: A linked data study

BACKGROUND

Women prisoners are a growing portion of the prison population. Health and social outcomes of their children have been studied and found to be poor, but little is known about child protection outcomes.

OBJECTIVES

Ascertain child protection system contact of children exposed to maternal incarceration.

PARTICIPANTS AND SETTING

All children born between 1985 and 2011 exposed to the incarceration of their mothers in a Western Australian correctional facility and a matched comparison group.

METHODS

A matched cohort study using linked administrative data on 2637 mothers entering prison between 1985 and 2015 and their 6680 children. We estimated hazard ratios (HRs) and incidence rate ratios (IRRs) of child protection service (CPS) contact post maternal incarceration (four concern levels), comparing rates for children exposed to maternal incarceration with a matched non-exposed group, adjusting for maternal and child factors.

FINDINGS

Exposure to maternal incarceration increased risk of CPS contact. Unadjusted HRs exposed vs unexposed children were 7.06 (95%CI = 6.49-7.69) for substantiated child maltreatment and 12.89 (95%CI = 11.42-14.55) for out-of-home care (OOHC). Unadjusted IRRs were 6.04 (95%CI = 5.57-6.55) for number of substantiations and 12.47 (95%CI = 10.65-14.59) for number of removals to OOHC. HRs and IRRs were only slightly attenuated in adjusted models.

CONCLUSIONS

Maternal incarceration is a warning flag for a child at high risk of serious child protection concerns. Family-friendly rehabilitative women's prisons, incorporating support for more nurturing mother-child relationships could provide a placed-based public health opportunity for disrupting distressing life trajectories and intergenerational pathways of disadvantage of these vulnerable children and their mothers. This population should be a priority for trauma-informed family support services.

Health impairment allegations against doctors: Qualitative analysis and insights for Australian general practitioners

METHOD

A thematic analysis was conducted of semistructured interviews with 21 doctor-patients and four doctors' health experts.

RESULTS

Doctor-patient participants had experienced a past or family psychiatric history, personal loss or trauma, access to drugs at work, workplace stress or recent patient death or suicide. Many avoided seeking care and were significantly unwell when notified to medical regulators. Regulatory processes caused distress, symptom relapse, suicidality, financial pressures and work difficulties. Doctor-patient participants sought assistance from GPs, doctors' health services, medical defence organisations, recovery groups and benevolent associations.

DISCUSSION

When treating doctor-patients, GPs can consider targeted mental health screening, openly discussing mandatory reporting obligations and accessing advice from their medical defence organisation or local doctors' health service. Trust and clear communication benefits doctor-patients and the wider communities they serve.

The rate of transition to a suicide attempt among people with suicidal thoughts in the general population: A systematic review

INTRODUCTION

While suicidal thoughts are relatively common in the general population, roughly affecting one in ten people during their lifetime, the transition from suicidal thoughts to a suicide attempt is rarer. There is limited consensus on the transition rate from suicidal ideation to suicide attempts.

OBJECTIVE

To review and summarize evidence on the rate of transition from suicidal ideation to a suicide attempt, and the factors associated with this transition, in the general population.

METHODS

A comprehensive search was conducted using MEDLINE, PsycINFO, and Embase for relevant articles published between January 1, 2000, and March 3, 2021. We identified 18 eligible studies that examined the transition from suicidal ideation to a suicide attempt in non-clinical populations. We assessed the quality of the included studies using the MASTER scale. The review has been registered with PROSPERO (CRD42021248325).

RESULTS

Rates of transitioning to a suicide attempt among people with suicidal ideation varied substantially across studies, from 2.6 % to 37 %. Follow-up periods also varied substantially, from 12 to 300 months, impeding reliable comparisons across studies or pooling data for further analyses. The most examined risk factors were mental health disorders such as major depressive and anxiety disorders, which were typically associated with higher odds of transition to a suicide attempt.

LIMITATIONS

High level of heterogeneity and limited quality of the studies.

CONCLUSION

The risk of transition from suicidal thoughts to a suicide attempt is moderate to high. Further longitudinal research is required to refine the rate and explore social determinants of transition from suicidal ideation to suicide attempts.

Testing the Impact of the #chatsafe Intervention on Young People's Ability to Communicate Safely About Suicide on Social Media: Protocol for a Randomized Controlled Trial

BACKGROUND

Suicide is the leading cause of death among Australians. One commonly cited explanation is the impact of social media, in particular, the ways in which young people use social media to communicate about their own experiences and their exposure to suicide-related content posted by others. Guidelines designed to assist mainstream media to safely report about suicide are widespread. Until recently, no guidelines existed that targeted social media or young people. In response, we developed the #chatsafe guidelines and a supporting social media campaign, which together make up the #chatsafe intervention. The intervention was tested in a pilot study with positive results. However, the study was limited by the lack of a control group.

OBJECTIVE

The aim of this study is to assess the impact of the #chatsafe social media intervention on young people's safety and confidence when communicating on the web about suicide.

METHODS

The study employs a pragmatic, parallel, superiority randomized controlled design. It will be conducted in accordance with the Consolidated Standards of Reporting Trials statement over 18 months. Participants will be 400 young people aged 16-25 years (200 per arm). Participants will be recruited via social media advertising and assessed at 3 time points: time 1-baseline; time 2-8-week postintervention commencement; and time 3-4-week postintervention. They will be asked to complete a weekly survey to monitor safety and evaluate each piece of social media content. The intervention comprises an 8-week social media campaign including social media posts shared on public Instagram profiles. The intervention group will receive the #chatsafe suicide prevention content and the control group will receive sexual health content. Both groups will receive 24 pieces of content delivered to their mobile phones via text message. The primary outcome is safety when communicating on the web about suicide, as measured via the purpose-designed #chatsafe online safety questionnaire. Additional outcomes include willingness to intervene against suicide, internet self-efficacy, safety, and acceptability.

RESULTS

The study was funded in November 2020, approved by the University of Melbourne Human Research Ethics Committee on October 7, 2022, and prospectively registered with the Australian New Zealand Clinical Trials registry. Trial recruitment began in November 2022 and study completion is anticipated by June 2024.

CONCLUSIONS

This will be the first randomized controlled trial internationally to test the impact of a social media intervention designed to equip young people to communicate safely on the web about suicide. Given the rising rates of youth suicide in Australia and the acceptability of social media among young people, incorporating social media-based interventions into the suicide prevention landscape is an obvious next step. This intervention, if effective, could also be extended internationally, thereby improving web-based safety for young people not just in Australia but globally.

Australian and New Zealand doctors' experiences of disciplinary notifications, investigations, proceedings and interventions relating to alleged mental health impairment: a qualitative analysis of interviews

When poor mental health impairs a doctor's ability to safely practise medicine, poor patient outcomes can result. Medical regulators play a critical role in protecting the public from impaired doctors, by requiring monitoring and treatment. However, regulatory processes may paradoxically harm doctors, with potential adverse implications for the community. There is little prior research examining the experiences of doctors with prior mental health or substance use challenges who are subject to regulatory notifications and processes relating to their health. Therefore, we explored this issue through the thematic analysis of semi-structured qualitative interviews. Participants reported that mandated treatment improved aspects of their health, but that fear of regulatory processes delayed them seeking treatment. Participants recognised being significantly unwell at the time of regulatory notification. Participants told us that regulatory processes triggered psychological distress, symptom relapse, and adverse financial and vocational implications. They also told us that these processes eroded their trust in regulators and regulatory processes. To improve health outcomes for unwell doctors and to create safer healthcare for the community, we propose: 1) greater awareness and education of the medical profession about the thresholds and requirements for mandatory reporting of health impairment; 2) better integrating specialised doctors' health services into existing regulatory pathways; and 3) adoption of a more therapeutic approach to regulation by medical regulators.

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.

Suicide Trends during the COVID-19 pandemic and the International COVID-19 Suicide Prevention Research Collaboration

Introduction

There was and still is much speculation about the COVID-19 pandemic impact on suicide rates. We aimed to assess the effect of the COVID-19 pandemic on suicide rates around the world.

Methods

We sourced real-time suicide data from countries or countries areas through a systematic internet search (official websites of Ministries of health, police agencies, and government-run statistics agencies or equivalents), recourse to our networks (e.g. ICSPRC) and the published literature (a living systematic review). We used an interrupted time-series analysis to model the trend in monthly suicides before COVID-19 in each country or country area, comparing the expected number of suicides derived from the model with the observed number of suicides in the early months of the pandemic (from April 1 to July 31, 2020, in the primary analysis). We have now updated this work to cover the first 15 months of the pandemic and stratified analyses by age and sex and method. We will present findings from the new updated data (35 countries) at the conference.

Results

Initially we sourced data from 21 countries (16 high-income and five upper-middle-income countries). Rate ratios (RRs) and 95% CIs based on the observed versus expected numbers of suicides showed no evidence of a significant increase in risk of suicide since the pandemic began in any country or area. There was statistical evidence of a decrease in suicide compared with the expected number in 12 countries or areas.

Conclusions

This was the first study to examine suicides occurring in the context of the COVID-19 pandemic in multiple countries. Early on high-income and upper-middle-income countries, suicide numbers remained largely unchanged or declined compared with the expected levels based on the pre-pandemic period. We need to remain vigilant and be poised to respond as the longer-term mental health and economic effects of the pandemic unfold. We will present updated findings with more recent data.

Using the Patient Health Questionnaire to estimate prevalence and gender differences of somatic symptoms and psychological co-morbidity in a secondary inpatient population with abdominal pain

BACKGROUND

Somatic disorders and somatic symptoms are common in primary care populations; however, little is known about the prevalence in surgical populations. Identification of inpatients with high somatic symptom burden and psychological co-morbidity could improve access to effective psychological therapies.

METHODS

Cross-sectional analysis (n = 465) from a prospective longitudinal cohort study of consecutive adult admissions with non-traumatic abdominal pain, at a tertiary hospital in New South Wales, Australia. We estimated somatic symptom prevalence with the Patient Health Questionnaire-15 at three cut-points: moderate (⩾10), severe (⩾15) and 'bothered a lot' on ⩾3 symptoms; and psychological co-morbidity with the Patient Health Questionnaire-9 and Generalized Anxiety Disorder-7 at standard (⩾10) cut-points. We also examined gender differences for somatic symptoms and psychological co-morbidity.

RESULTS

Prevalence was moderate (52%), female predominance (odds ratio = 1.71; 95% confidence interval = [1.18, 2.48]), severe (20%), no gender difference (1.32; [0.83, 2.10]) and 'bothered a lot' on ⩾3 symptoms (53%), female predominance (2.07; [1.42, 3.03]). Co-morbidity of depressive, anxiety and somatic symptoms ranged from 8.2% to 15.9% with no gender differences.

CONCLUSION

Somatic symptoms were common and psychological triple co-morbidity occurred in one-sixth of a clinical population admitted for abdominal pain. Co-ordinated surgical and psychological clinical intervention and changes in clinical service organisation may be warranted to provide optimal care.

Vocational and psychosocial predictors of medical negligence claims among Australian doctors: a prospective cohort analysis of the MABEL survey

OBJECTIVE

To understand the association between medical negligence claims and doctors' sex, age, specialty, working hours, work location, personality, social supports, family circumstances, self-rated health, self-rated life satisfaction and presence of recent injury or illness.

DESIGN AND SETTING

Prospective cohort study of Australian doctors.

PARTICIPANTS

12 134 doctors who completed the Medicine in Australia: Balancing Employment and Life survey between 2013 and 2019.

PRIMARY OUTCOME MEASURE

Doctors named as a defendant in a medical negligence claim in the preceding 12 months.

RESULTS

649 (5.35%) doctors reported being named in a medical negligence claim during the study period. In addition to previously identified demographic factors (sex, age and specialty), we identified the following vocational and psychosocial risk factors for claims: working full time (OR=1.48, 95% CI 1.13 to 1.94) or overtime hours (OR 1.70, 95% CI 1.29 to 2.23), working in a regional centre (OR 1.69, 95% CI 1.37 to 2.08), increasing job demands (OR 1.16, 95% CI 1.04 to 1.30), low self-rated life satisfaction (OR 1.43, 95% CI 1.08 to 1.91) and recent serious personal injury or illness (OR 1.40, 95% CI 1.13 to 1.72). Having an agreeable personality was mildly protective (OR 0.91, 95% CI 0.83 to 1.00). When stratified according to sex, we found that working in a regional area, low self-rated life satisfaction and not achieving work-life balance predicted medical negligence claims in male, but not female, doctors. However, working more than part-time hours and having a recent personal injury or illness predicted medical negligence claims in female, but not male, doctors. Increasing age predicted claims more strongly in male doctors. Personality type predicted claims in both male and female doctors.

CONCLUSIONS

Modifiable risk factors contribute to an increased risk of medical negligence claims among doctors in Australia. Creating more supportive work environments and targeting interventions that improve doctors' health and well-being could reduce the risk of medical negligence claims and contribute to improved patient safety.

Medical negligence claims and the health and life satisfaction of Australian doctors: a prospective cohort analysis of the MABEL survey

OBJECTIVE

To assess the association between medical negligence claims and doctors' self-rated health and life satisfaction.

DESIGN

Prospective cohort study.

PARTICIPANTS

Registered doctors practising in Australia who participated in waves 4 to 11 of the Medicine in Australia: Balancing Employment and Life (MABEL) longitudinal survey between 2011 and 2018.

PRIMARY AND SECONDARY OUTCOME MEASURES

Self-rated health and self-rated life satisfaction.

RESULTS

Of the 15 105 doctors in the study, 885 reported being named in a medical negligence claim. Fixed-effects linear regression analysis showed that both self-rated health and self-rated life satisfaction declined for all doctors over the course of the MABEL survey, with no association between wave and being sued. However, being sued was not associated with any additional declines in self-rated health (coef.=-0.02, 95% CI -0.06 to 0.02, p=0.39) or self-rated life satisfaction (coef.=-0.01, 95% CI -0.08 to 0.07, p=0.91) after controlling for a range of job factors. Instead, we found that working conditions and job satisfaction were the strongest predictors of self-rated health and self-rated life satisfaction in sued doctors. In analyses restricted to doctors who were sued, we observed no changes in self-rated health (p=0.99) or self-rated life satisfaction (p=0.59) in the years immediately following a claim.

CONCLUSIONS

In contrast to prior overseas cross-sectional survey studies, we show that medical negligence claims do not adversely affect the well-being of doctors in Australia when adjusting for time trends and previously established covariates. This may be because: (1) prior studies failed to adequately address issues of causation and confounding; or (2) legal processes governing medical negligence claims in Australia cause less distress compared with those in other jurisdictions. Our findings suggest that the interaction between medical negligence claims and poor doctors' health is more complex than revealed through previous studies.

Suicide among those who use mental health services: Suicide risk factors as evidenced from contact-based characteristics in Victoria

OBJECTIVE

The majority of suicide decedents have had contact with health services in the months before their death. Contacts for mental health services present potential suicide prevention opportunities. This study aims to compare contact-based characteristics among suicide decedents and living controls in the year subsequent to clinical mental health contact with the public health system in Victoria, Australia.

METHODS

A population-based nested case-control study of those who had mental health-related hospital and community contacts with the public health system was conducted. Cases (suicide decedents) were age and gender-matched to living controls (suicide non-decedents). These records were linked to records of suicides that occurred in the 12 months following the health service contact, between January 1, 2011, and December 31, 2016. Victorian residents aged 10 years and above were selected at the time of contact (483,933 clients). In the study population, conditional logistic regression models were used to assess the relationship between contact-based characteristics and suicide. Socio-demographics and mental health-related hospital and community contact data was retrieved from the Victorian Admitted Episodes Dataset, the Victorian Emergency Minimum Dataset and the Public Clinical Mental Health database and suicide data from the Victorian Suicide Register.

RESULTS

During a six-year period, 1,091 suicide decedents had at least one mental health contact with the public health system in the 12 months preceding the suicide. Overall, controls used more mental health services than cases; however, cases used more mental health services near the event. The relationship between the type of service and suicide differed by service type: hospital admissions and emergency department presentations had a significant positive association with suicide with an OR of 2.09 (95% CI 1.82-2.40) and OR of 1.13 (95% CI 1.05-1.22), and the effect size increased as the event approached, whereas community contacts had a significant negative association with an OR of 0.93 (95% CI 0.92-0.94), this negative association diminished in magnitude as the event approached (OR∼1).

CONCLUSION

Suicide decedents had less contact with mental health services than non-decedents; however, evidence suggests suicide decedents reach out to mental health services proximal to suicide. An increase in mental health service contact by an individual could be an indication of suicide risk and therefore an opportunity for intervention. Further, community level contact should be further explored as a possible prevention mechanism considering the majority of suicide decedents do not access the public clinical mental health services.

1196Trajectories of disability throughout adolescence and labour force status as a young adult

Background

Young people with disabilities have poorer labour force outcomes than their peers without disabilities. Existing studies typically assess disability at one time point, obscuring potential variation in the experience of disability over time. This study aimed to identify trajectories of disability during childhood/adolescence and assess associations between trajectory membership and labour force status in young adulthood.

Methods

Group-based trajectory modeling was applied to disability status information from Waves 2-7 (age 4/5 to 16/17 years) of the Longitudinal Study of Australian Children; labour force participation (employed, unemployed, not in the labour force (NILF)) was measured at Wave 8 (18/19 years). Two logistic regression models assessed the relationship between trajectory group membership and labour force participation, adjusted for confounders.

Results

Four trajectory groups were identified: low (75.5% of cohort), low increasing (9.7%), high decreasing (10.9%), and consistently high (3.9%) prevalence of disability. Compared to individuals in the low trajectory (reference group), individuals in the consistently high trajectory had increased odds of being NILF at age 18/19 years (AOR 3.48, 95%CI 2.14, 5.68). Individuals in the low increasing trajectory had increased odds of unemployment at age 18/19 years compared to the reference group (AOR 2.93, 95%CI 1.91-4.48).

Conclusions

Results suggest that early experiences of disability among young Australians may differentially impact future labour force outcomes.

Key messages

Additional supports to prepare young people for the labour force should focus on individuals with consistently high or increasing prevalence of disability trajectories.

535The epidemiology of all-cause and cause-specific mortality following release from prison in 11 countries

Background

More than 30 million adults are released from incarceration globally each year. Many experience complex physical and mental health problems, and are at markedly increased risk of preventable mortality. Despite this, evidence regarding the global epidemiology of mortality following release from incarceration is insufficient to inform the development of targeted, evidence-based responses. Many previous studies have suffered from inadequate power and poor precision, and even large studies have limited capacity to disaggregate data by specific causes of death, sub-populations or time since release to answer questions of clinical and public health relevance.

Methods

We aimed to comprehensively document the incidence, timing, causes and risk factors for mortality in adults released from incarceration. We created the Mortality After Release from Incarceration Consortium (MARIC), a multi-disciplinary collaboration representing 29 cohorts of adults who have experienced incarceration from 11 countries. Findings across cohorts will be analysed using a two-step, individual participant data meta-analysis methodology.

Results

Using linked data from the 29 individual cohorts, the combined sample includes 1,337,993 individuals (89% male), with 75,795 deaths recorded over 9,191,393 person-years of follow-up. Preliminary analyses indicate a marked elevation in mortality risk following release from incarceration, with this risk beginning on the day of release. At the time of writing, more detailed analyses are underway regarding all-cause and cause-specific deaths – along with risk and protective factors – and findings will be presented at the WCE conference.

Conclusions

The MARIC consortium represents an important advancement in the field, bringing international attention to this problem.

Key messages

The MARIC consortium will provide internationally relevant evidence to guide policymakers and clinicians in reducing preventable deaths in this marginalised population.

P36: SOMATIC SYMPTOM DISORDER (SSD) AND ABDOMINAL PAIN: INCREASED OPIOID PRESCRIBING IN SURGICAL PATIENTS

Introduction

Undifferentiated pain, and pain out of proportion of diagnosed pathology are sources of frustration to clinician and patient. SSD is a DSM-V diagnosis that has consolidated the previous diagnoses of psychogenic pain. It is a health anxiety condition, where sufferers experience multiple somatic symptoms which cause anxiety and distress. This anxiety results in frequent ED and GP presentations, extensive investigations, and increased opioid prescription. However, opioids do little to alleviate symptoms. Treatment should focus on underlying anxiety and depression.

Population studies show SSD prevalence to be 15-20%, however SSD has never been studied in the surgical population. We hypothesized that the rates of SSD in the surgical population reflects that in primary care, and that SSD sufferers are more likely to be prescribed opioid analgesia.

Method

Adult patients admitted with abdominal pain of any non-traumatic aetiology to the Acute General Surgical Unit at a major tertiary hospital are being screened for SSD using the PHQ-15 questionnaire, and opioid prescription is being recorded.

Result

400 participants have been recruited with a total SSD prevalence of 20%. Opioid prescribing rises sharply with SSD diagnosis. The average opioid prescription appears to be 3 times higher in patients with SSD compared to those without.

Conclusion

Our data confirms an SSD prevalence of 20% in the surgical population. This is associated with increased opioid prescription. Early recognition of SSD and implementation of appropriate treatment could reduce hospital presentations, admissions and opioid prescription. We will continue recruitment to 800 participants by March 2020.

Take-home message

SSD is common in all populations, and results in increased hospital presentations, admissions and opioid prescription. Early recognition and implementation of appropriate treatment may reduce healthcare burden, improve patient outcomes, and reduce opioid prescription.

Socioeconomic Disadvantage, Mental Health and Substance Use in Young Men in Emerging Adulthood

Emerging adulthood is a neglected phase of the life course in health research. Health problems and risk behaviors at this time of life can have long-term consequences for health. The 2016 Lancet Commission on Adolescent Health and Wellbeing reported that the influence of socioeconomic factors was under-researched among adolescents and young adults. Moreover, the influence of socioeconomic factors on health has been little researched specifically in emerging adult men. We aimed to investigate associations between socioeconomic disadvantage and mental health, suicidal behavior, and substance use in young adult Australian men. Logistic regression was used to examine the association between Year 12 (high school) completion and area disadvantage on mental health, suicidal behavior, and substance use in 2,281 young men age 18-25 participating in the Australian Longitudinal Study on Male Health (Ten to Men). In unadjusted analysis both Year 12 non-completion and area disadvantage were associated with multiple adverse outcomes. In adjusted analysis Year 12 non-completion, but not area disadvantage, was associated with poorer mental health, increased odds of suicidal behavior, and substance use. Retaining young men in high school and developing health-promotion strategies targeted at those who do exit education early could both improve young men's mental health and reduce suicidal behavior and substance use in emerging adulthood.

Using Linked Data to Examine the Epidemiology of All-Cause and Cause-Specific Mortality Following Release from Incarceration in Eleven Countries

IntroductionMore than 30 million adults are released from incarceration globally each year. Many experience complex physical and mental health problems, and are at markedly increased risk of preventable mortality. Despite this, evidence regarding the global epidemiology of mortality following release from incarceration is insufficient to inform the development of targeted, evidence-based responses.

Confidence and Intentions to Help a Person at Risk of Suicide

OBJECTIVE

We aimed to identify Australian adults' current level of confidence and intentions to help a person close to them in distress or at risk of suicide to inform the content and targeting of suicide prevention messages aimed at family and friends of those at risk.

METHODS

We conducted a nationally representative computer-assisted telephone survey of confidence and intentions to help someone in distress or at risk of suicide (n = 3,002). We used logistic regression to determine whether sociodemographic and exposure variables predicted confidence and intentions to help.

RESULTS

Confidence to help was high. About half of the respondents had intentions inconsistent with best practice. Listening and talking, and encouraging the person to seek professional help were the most common types of intended helping actions. Intentions to ask suicide risk assessment questions were least common. Men were more likely than women to have intentions to carry out nonrecommended actions, and less likely to have intentions to carry out recommended actions.

CONCLUSIONS

Suicide prevention messaging aimed at family and friends could encourage them to ask direct questions about suicide risk and could include messages about "what not to do." Suicide prevention messages aimed specifically at men are indicated.

The impact of substance use on treatment as a compulsory patient

OBJECTIVES

This paper considers the impact of having a diagnosis of substance use disorder on the utilisation of compulsory orders under the Victorian Mental Health Act (2014).

METHODS

We analysed the subsequent treatment episodes over 2 years of people who had been on a community treatment order for at least 3 months and determined the odds of a further treatment order if there was a diagnosis of substance use at or about the time the index community treatment order ended.

RESULTS

An additional diagnosis of a substance use disorder was coded in 47.7% and was associated with significantly increased odds of a subsequent treatment order in the following 2 years for those with a main diagnosis of schizophrenia (AOR = 3.03, p<0.001) and 'other' disorders (AOR = 11.60, p=0.002). Those with a main diagnosis of mood disorder had a significant increase in odds for an inpatient treatment order if there was an additional substance use disorder diagnosis (AOR = 3.81, p=0.006).

CONCLUSIONS

Having an additional diagnosis of substance use disorder was associated with increased likelihood of being placed on an order. This study supports greater emphasis being given to treatment of substance use concurrently with that of mental illness.

Self-harm following release from incarceration: Patterns and measurement issues

IntroductionDespite an elevated prevalence of self-harm in the incarcerated adult population, little is known about patterns of self-harm following release from prison. Objectives and ApproachBaseline self-report interviews with 1315 adults immediately prior to release from prison in Queensland, Australia, combined with interrogation of linked health data from >3750 post-release emergency department presentations, >2000 ambulance attendances, and corrections data during periods of re-incarceration. ResultsApproximately 5% of all contacts with medical emergency services following release from prison resulted from self-harm. These were associated with being Indigenous, having a lifetime history of a mental disorder and having been identified by prison staff as being at risk of self-harm. Agreement between self-reported self-harm and medically-verified episodes of self-harm was poor. Conclusion/ImplicationsEmergency services contacts resulting from self-harm following release from prison are common and represent an opportunity for tertiary intervention for self-harm. Our findings suggest that a self-reported history of self-harm should not be considered a reliable indicator of prior self-harm, or of future self-harm risk, in incarcerated adults.

The Mortality After Release from Incarceration Consortium (MARIC) study: Strengths of international data linkage

IntroductionAdults released from incarceration experience complex physical and mental health problems, and are at markedly increased risk of preventable death. Despite this, not enough is known about the granular epidemiology of mortality in this population to inform development of targeted, evidence-based responses. Objectives and ApproachWe created the Mortality After Release from Incarceration Consortium (MARIC), a multi-disciplinary collaboration from 12 countries representing 30 cohorts of adults with a history of incarceration. The combined sample size is 1,210,168, with 58,840 deaths recorded over 8,261,743 person-years of follow-up time. In this protocol paper, using a two-step, individual participant data meta-analysis (IPDM-A) methodology involving 22 MARIC cohorts, we calculated 1) a crude mortality rate (CMR; with 95% confidence intervals) for each individual cohort over the first 84 days (12 weeks) following release; and 2) a combined, meta-analysed CMR for the same period. ResultsOf 1,704,208 individual releases, we observed 4,018 deaths over the first 84 days. The overall CMR over the first 84 days after release was 1610.97 deaths per 100,000 person-years (95% CI: 1263.4 - 1958.5). The rate was highest on the day of release (5768.0; 95% CI: 3296.5 - 8239.4), which was significantly higher than on days 4-84. Conclusion/ImplicationsAdults released from incarceration were at an acutely increased risk of death on the day of release, and this risk remained elevated for at least the first 12 weeks. The MARIC study will provide decisive and empirical evidence to guide clinicians and policy makers in reducing mortality in this marginalized

Deaths in young people after contact with the youth justice system: a retrospective data linkage study

IntroductionYoung people who have contact with the youth justice system are distinguished by a high prevalence of complex, co-occurring health problems, including known risk factors for preventable mortality. However, almost nothing is known about health outcomes for these young people after separation from the youth justice system. Objectives and ApproachWe aimed to examine the incidence, timing, causes and risk factors for death in justice-involved young people. We linked youth justice records in Queensland, Australia 1993-2016 (N=48,963) with adult correctional records and the National Death Index. We split the cohort into three subgroups: those who had ever been in detention (n=7,643), those supervised in the community but never detained (n=12,953), and those charged with an offence but never convicted (n=28,367). We calculated all-cause and cause-specific crude mortality rates (CMRs), and indirectly standardised mortality ratios (SMRs). We used Cox regression to identify static and time-varying risk factors for death. ResultsDuring a median of 13.6 years of follow-up there were 1,452 deaths (3.0%). The all-cause CMR was 2.2 (95%CI 2.1-2.3) per 1000 person-years, and the all-cause SMR was 3.1 (95%CI 3.0-3.3). The leading external causes of death were suicide (32% of all deaths), transport accidents (16%), accidental drug-related causes (13%), and violence (3%). In adjusted analyses, independent risk factors for all-cause mortality included being male (HR=1.4, 95%CI 1.2-1.6) and older (>=15 vs. vs. charge only; HR=1.6, 95%CI 1.2-2.0) and subsequent incarceration as an adult (HR=1.8, 95%CI 1.4-2.4). Conclusion/ImplicationsYoung people who have contact with the youth justice system are at markedly increased risk of preventable death, after separation from that system. Efforts to improve long-term health outcomes for justice-involved youth have the potential to reduce preventable deaths in these highly vulnerable young people.

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.

Compensation seeking and disability after injury: the role of compensation-related stress and mental health

OBJECTIVE

Claiming for compensation after injury is associated with poor health outcomes. This study examined the degree to which compensation-related stress predicts long-term disability and the mental health factors that contribute to this relationship.

METHOD

In a longitudinal, multisite cohort study, 332 injury patients (who claimed for compensation) recruited from April 2004 to February 2006 were assessed during hospitalization and at 3 and 72 months after injury. Posttraumatic stress, depression, and anxiety symptoms (using the Mini-International Neuropsychiatric Interview) were assessed at 3 months; compensation-related stress and disability levels (using the World Health Organization Disability Assessment Schedule II) were assessed at 72 months.

RESULTS

A significant direct relationship was found between levels of compensation-related stress and levels of long-term disability (β = 0.35, P < .001). Three-month posttraumatic stress symptoms had a significant relationship with compensation-related stress (β = 0.29, P < .001) as did 3-month depression symptoms (β = 0.39, P < .001), but 3-month anxiety symptoms did not. A significant indirect relationship was found for posttraumatic stress symptoms and disability via compensation stress (β = 0.099, P = .001) and for depression and disability via compensation stress (β = 0.136, P < .001).

CONCLUSIONS

Stress associated with seeking compensation is significantly related to long-term disability. Posttraumatic stress and depression symptoms increase the perception of stress associated with the claims process, which in turn is related to higher levels of long-term disability. Early interventions targeting those at risk for compensation-related stress may decrease long-term costs for compensation schemes.

Substance use and risk of death in young offenders: a prospective data linkage study

INTRODUCTION AND AIMS

Young offenders are at increased risk of preventable death after release from custody, but risk factors for death in this population are poorly understood. Despite their poor health profiles, no studies have examined mortality outcomes in young people who have served community-based orders. The aims of this study were to describe the causes and identify risk factors for death in a cohort of young offenders in Victoria, Australia.

DESIGN AND METHODS

We interviewed young people serving a custodial (n = 273) or community-based order (n = 242) in Victoria, Australia in 2002-2003. Measures included demographics and family history, offence history, experience of victimisation, mental illness, self-harm and substance use. Deaths up to 31 December 2011 were identified through a probabilistic linkage with the National Death Index.

RESULTS

The all-cause crude mortality rate was 4.2 (95% confidence interval 2.7-6.8) per 1000 person years and was not significantly different for those who had served custodial and community-based orders. Most deaths were due to drug overdose, traffic accidents or suicide. Adjusting for age, sex and order type, risk factors for death from the baseline interview included weekly use of opioids, sleeping pills or painkillers, polydrug use and injecting drug use.

DISCUSSION AND CONCLUSIONS

Young people who have served community-based and custodial orders are at an increased risk of preventable death. Those engaging in risky substance use, particularly injecting drug use and use of multiple central nervous system depressants, are at greatest risk. There is an urgent need to develop and rigorously evaluate preventive interventions.

Patterns and predictors of primary mental health service use following bushfire and flood disasters

BACKGROUND

Mental health care services play an important role following disasters (Reifels et al., 2013). The aim of this study is to examine patterns and predictors of primary mental health care service use, following two major Australian natural disaster events.

METHOD

Utilizing referral and session data from a national minimum dataset, descriptive and regression analyses were conducted to identify levels and predictors of the use of the Access to Allied Psychological Services (ATAPS) program over a 2-year period following two major Australian bushfire and flood/cyclone disasters. Predictor variables examined in negative binomial regression analysis included consumer (age, gender, household structure, previous mental health care history, and diagnosis) and event characteristics (disaster type).

RESULTS

The bushfire disaster resulted in significantly greater service volume, with more than twice the number of referrals and nearly three times the number of sessions. Service delivery for both disasters peaked in the third quarter. Consumers affected by bushfires, diagnosed with depression, anxiety, or both of these disorders utilized sessions at significantly higher rates.

CONCLUSIONS

The substantial demand for primary mental health services following disaster can vary with disaster type. Disaster type and need-based variables as key drivers of service use intensity indicate an equitable level of service use. Established usage patterns assist with estimating future service capacity requirements. Flexible referral pathways can enhance access to disaster mental health care. Future research should examine the impact of program- and agency-level factors on mental health service use and factors underpinning treatment non-adherence following disaster.

Response time of pulse oximeters assessed using acute decompression

In human volunteers, the response times of 11 pulse oximeters to a 10% step reduction in arterial oxygen saturation were measured using an acute decompression technique. When finger probes were used, nine oximeters had similar response times and two were significantly slower (P less than 0.05). The ear probe response time was similar on six oximeters assessed, and faster than the finger probes. The response times of the oximeters to an acute increase in arterial saturation were tested by suddenly changing the inspired gas from air to 100% oxygen at an ambient pressure of 380 mm Hg. For ear probes, the response times were similar for all oximeters; for finger probes, three fast-responding and three slow-responding oximeters were identified (P less than 0.05). A faster response could be elicited by placing the probes on the thumb (P less than 0.05). We conclude that if a rapid indication of changes in arterial saturation is required, pulse oximeters with ear probes should be used. If finger probes are used, they should be placed on the thumb. The oximeter used will influence the response time if finger probes are used, but it will have little effect if ear probes are used.
