Identifying Typologies of Persons Who Died by Suicide: Characterizing Suicide in Victoria, Australia

Availability and quality of data related to cultural and linguistic diversity in the Victorian Suicide Register: A pilot study

OBJECTIVE

While people from culturally and linguistically diverse (CALD) backgrounds have been identified as a priority for suicide prevention in Australia, little is known about suicide in CALD communities. We aim to describe the availability and quality of CALD data in the Victorian Suicide Register (VSR).

METHODS

A retrospective consecutive case series review of suicides reported to the Coroners Court of Victoria during 2016 was conducted. Using the VSR, we identify suicides showing evidence of CALD identity and relevant variables were extracted and coded according to an adapted Australian Institute of Health and Welfare framework.

RESULTS

During 2016, 126 of 652 suicides (19.3%, 95% confidence intervals 16.4-22.6) were flagged as showing evidence of CALD. The two most frequent CALD indicators for which information was recorded were country of birth and year of arrival. There was less information pertaining to citizenship, residency/visa status, preferred language, English language proficiency and religious affiliation.

CONCLUSIONS

This study demonstrates that the VSR, like other databases, has substantial gaps in availability and quality of CALD data.

IMPLICATIONS

A framework to capture richer data on cultural, religious and linguistic diversity when coding suicides is needed to inform policy on suicide prevention initiatives designed for CALD communities.

Epidemiological characteristics and hospitalization trajectories prior to suicide in Galicia between 2013 and 2016

INTRODUCTION

Addressing suicide requires an understanding of regional patterns of epidemiology, with health variables being central. However, the clinical profile of people who commit suicide has received little attention. The objectives of this study were to analyze the sociodemographic, clinical, and forensic characteristics of persons who committed suicide in Galicia between 2013 and 2016, analyze suicide mortality rates, and identify trajectories of hospitalizations and associated variables.

MATERIAL AND METHODS

A population study was carried out on the 1354 people who died by suicide in Galicia.

RESULTS

The most common profile was a retired man, 57.9 years old (SD=18.5), from an urban and inner area. 43.6% had been previously hospitalized, 41.6% had been diagnosed with physical disorders, and 26.8% with mental disorders. 48.2% had been prescribed psychiatric medications and 29.6% had received outpatient psychiatric care. The highest prevalence of death by suicide (27.5%) was in 2014, with the predominant method being hanging (59.1%). The average raw rate was 12.3/100,000. Three trajectories of hospitalizations emerged: 94.83% had experienced few hospitalizations; 2.95% an increasing pattern; and 2.22% a decreasing pattern. These trajectories were associated with number of psychiatric appointments, prescription of psychiatric medications, and diagnoses of physical and mental disorders.

CONCLUSIONS

These findings are crucial for detection and prevention.

Identifying Points of Prevention in Firearm-Related Suicides: A Mixed-Methods Study Based on Coronial Records

PURPOSE

Firearm-related suicide is a noteworthy and preventable public health issue that has drawn limited attention in Australian research. Firearms are highly lethal and remain in the top three methods of suicide among Australian males. This study examines suicides occurring in Tasmania, the jurisdiction with the highest rate of firearm-related suicide, with the aim of aiding suicide prevention strategies.

METHODS

A mixed-methods approach was used to analyze data from the Tasmanian Suicide Register. The quantitative analysis examined socio-demographic factors, substance use, physical and mental health, and access to services for suicides occurring between January 1, 2012 and December 31, 2016. The qualitative analysis comprised firearm-related suicides occurring between January 1, 2012 and December 31, 2017.

RESULTS

Firearms users were more likely than those employing other means of suicide to be male, retired, and residing in remote areas but were less likely to have had a previous mental illness diagnosis or evidence of suicidal ideation or self-harming behaviors. There was some evidence of increased impulsiveness among firearm users. We found 54% of decedents were licensed to own a firearm at the time of death. Firearms most often belonged to the decedent (52%) and 26% sourced a firearm from family or friends. Only 58% of cases involved a firearm with a dedicated storage facility.

CONCLUSIONS

Prevention efforts need to take into account the unique profiles of those at risk of firearm-related suicide. Impulsiveness and the varying levels of adherence to firearms safety practices point to the need for strategies that limit physical access to firearms.HIGHLIGHTSFirearms-related suicides have a unique risk profile compared with other means of suicide.Mental illness diagnosis, suicidal thoughts, and self-harming behaviors were less commonly identified among firearms-related suicides than other means of suicide.Impulsiveness and the varying levels of adherence to firearms safety practices point to the need for strategies that limit physical access to firearms.

Factors associated with professional mental health service use among adults with suicidal ideation

BACKGROUND

The uptake of professional mental health services among people with suicidal ideation remains low, yet few community-based studies have characterised modifiable individual barriers to service use. Our aims were (1) to identify factors associated with use of professional mental health services among people experiencing suicidal ideation, and (2) to distinguish subgroups with varying levels of service use.

METHODS

1462 Australian adults (78.8% female) were recruited online to participate in a cross-sectional survey. Logistic regression analysis was used to identify factors associated with professional service use. A decision tree model was used to identify subgroups with varying rates of professional service use.

RESULTS

Most participants (62%) had used professional services for mental health concerns in the past 12 months. Greater rates of service use were observed in participants who were middle aged, spoke English, disclosed to informal sources or helplines, met criteria for a mental health disorder, had higher levels of entrapment, psychological distress, and disinhibition, and lower levels of detachment and antagonism. At the terminal nodes of the decision tree analysis, service use ranged from 21% to 94%. The most important determinants of service use were meeting criteria for a mental disorder and disclosure of suicidal ideation to family/friends and helplines.

CONCLUSION

These findings suggest that interventions to support the safe disclosure of suicidal ideation may assist in increasing service use. There is also the need for services that meet the needs of individuals who do not meet criteria for a mental health condition.

Comparison of Work-Related Stress in Cluster of Workers' Suicides in Korea: Analysis of Industrial Accident Compensation Insurance, 2010-2017

Background: There is limited research on the heterogeneity of worker suicides. We compared differences in workers’ suicides by clustering suicide deaths. Methods: From 2010 to 2017, 353 suicide deaths were claimed in the Industrial Accident Compensation Insurance; variables were coded using a standardized methodology. A two-step cluster analysis classified the clusters based on demographic and employment conditions. Details of the suicide, clinical variables, personal stresses, and work-related stresses were compared using the chi-square test and one-way analysis of variance. Results: We identified five clusters and they differed particularly in work-related stress. “Responsibility-burdened type” experienced excessive responsibility as managers; “role-changed type” experienced a sudden and unpredictable role change as clerks or sales workers; “risk-exposed type” experienced physical risk factors at work (working alone, outdoors, and in shifts) as machine operating and assembling workers, or craft and related trades workers; “job-insecurity type” experienced unstable employment (irregular, nonpermanent) as elementary or service workers; “workplace-violence type” was mainly unmarried women who lived alone, and experienced interpersonal conflict and violence as professionals and related workers. There were no differences between clusters in clinical variables (except problem drinking) and personal stresses. Conclusion: Interventions to alleviate work-related stress in worker clusters are needed to prevent suicide in workers.

Sociodemographic characteristics associated with hospital contact in the year prior to suicide: A data linkage cohort study in Victoria, Australia

Aims

The aims of this study were to examine the prevalence of hospital contact in the year prior to suicide in Victoria, Australia, and to compare characteristics among those who did and did not have contact in the year prior to suicide.

Methods

The study was a data linkage cohort study of 4348 Victorians who died by suicide over the period 2011–2017. Data from the Victorian Suicide Register (VSR) was linked with hospital separations and Emergency Department (ED) presentations datasets by the Centre for Victorian Data Linkages (CVDL). The main outcomes were: (1) hospital contact for any reason, (2) hospital contact for mental-health-related reasons, and (3) hospital contact for intentional self-harm. Unadjusted and adjusted odds ratios were calculated as the measures of association.

Results

In the year prior to suicide, half of the decedents (50.0%) had hospital contact for any reason (n = 2172), 28.6% had mental-health-related hospital contact (n = 1244) and 9.9% had hospital contact for intentional self-harm (n = 432).

In the year prior to suicide, when compared with males aged 25–49 years (the reference group):

males aged 75+ years and females of all ages were significantly more likely to have hospital contact for any reason

females aged 10–24 years and 25–49 years were significantly more likely to have mental-health-related hospital contact

females aged 10–24 years and 25–49 years had 3.5 times and 2.4 times the odds of having hospital contact for intentional self-harm.

Conclusions

The comparatively high proportion of female decedents with mental-health related hospital contact in the year prior to suicide suggests improving the quality of care for those seeking help is an essential prevention initiative; this could be explored through programs such as the assertive outreach trials currently being implemented in Victoria and elsewhere in Australia. However, the sizeable proportion of males who do not have contact in the year prior to suicide was a consistent finding and represents a challenge for suicide prevention. Programs to identify males at risk in the community and engage them in the health care system are essential. In addition, promising universal and selective interventions to reduce suicide in the cohort who do not have hospital contact, include restricting access to lethal means and other public health interventions are also needed.

Prevalence and Characteristics Associated with Chronic Noncancer Pain in Suicide Decedents: A National Study

OBJECTIVE

The aims were to estimate the prevalence of CNCP in suicide decedents, and compare sociodemographic and clinical characteristics of people who die by suicide (i) with and without a history of CNCP and (ii) among decedents with CNCP who are younger (<65 years) and older (65 + years).

METHOD

We examined all closed cases of intentional deaths in Australia in 2014, utilizing the National Coronial Information System.

RESULTS

We identified 2,590 closed cases of intentional deaths in Australia in 2014 in decedents over 18 years of age. CNCP was identified in 14.6% of cases. Decedents with CNCP were more likely to be older, have more mental health and physical health problems, and fewer relationship problems, and were more likely to die by poisoning from drugs, compared with decedents without CNCP. Comparisons of older and younger decedents with CNCP found that compared to younger (<65 years) decedents with CNCP, older decedents (65 + years) were less likely to have mental health problems.

CONCLUSIONS

This is the first national study to examine the characteristics of suicide deaths with a focus on people with CNCP. Primary care physicians should be aware of the increased risk for suicide in people living with CNCP, and it may be useful for clinicians to screen for CNCP among those presenting with suicidal behaviors.
