Jumping the gun: firearms and the mental health of Australians

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.

Suicide in Australia: Do We Really Have A Problem?

In 1995, 2367 Australians lost their lives through suicide, and up to 100 times this number may attempt each year: Suicide has now become a major public health problem in Australia, which has seen the suicide rates in young males quadruple over the last 35 years or so. An analysis of current research on suicide and suicidal behaviour exploring possible causes and crosscultural issues, is discussed. As well, an extended definition of suicide as an intentional death and its antecedents provides the foundation for a discourse on the views now held by our corntemporary society. The paper argues that suicide not only is one of the most extreme consequences of personal psychosocial distress but also is often also an indicator of previous life events and environmental factors that potentiates for personal vulnerabilities.

Firearms regulation, violence and the mentally ill: a contemporary Antipodean appraisal

As recent cases of mass murder at Utoya Island in Norway, and in the United States (US) at Virginia Tech, Virginia; Tucson, Arizona; Aurora, Colorado; and Newtown, Connecticut all illustrate, acts of extreme violence involving high powered weapons and committed by persons with a presumed or confirmed mental illness tend to arouse intense public and political debates about the efficacy of firearm regulation and control. Following these tragedies, in the US at least, various law reform measures have been proposed and in some cases implemented designed principally to make it more difficult for mentally ill persons to gain access to firearms. In this article it is contended that measures like these are at best tinkering with the margins of gun control and also have the tendency to reinforce the stigma and discrimination experienced by persons with a mental illness, while perpetuating stereotypes of them as dangerous to themselves and others. Despite these limitations, and while firearm regulation policies and practices vary widely across the globe, most nations still seek in some way to limit access to guns by persons with a mental illness. This article explores in more detail how such policies and practices have been applied in the Australian State of New South Wales and the lessons to be learned elsewhere from this experience.

Suicide prevention and method restriction: evaluating the impact of limiting access to lethal means among young Australians

Given the finite resources allocated to suicide prevention, it is necessary to direct resources into interventions that are most likely to have an impact. This article tests for possible impacts on youth suicides of a cost-intensive Australian policy change (increased firearms restriction) that limited access to a means of suicide. Suicide rates by different age groups and methods were examined for structural breaks, using Zivot-Andrews and Quandt tests. No breakpoint was found in firearm suicide among Australian youth around the time of the 1996 legislative changes. Method restriction in the form of firearms legislation could not be tied to a corresponding impact on youth suicide.

The decline in Australian young male suicide

Since the late 1990s there has been a sharp downward trend in Australian young male suicide. It is possible that a major government youth suicide prevention initiative, the National Youth Suicide Prevention Strategy (NYSPS), implemented during 1995-1999 may have influenced the decline. In this article, we examine time trends in age- and means-specific male and female Australian suicide rates in relation to unemployment rates and the NYSPS. Based on Australian suicide data over the period 1966-2003, we assess secular changes in the 20-24 year male suicide to total (crude) male suicide rate ratio in relation to the NYSPS, using interrupted time series analysis (ARIMA), since this was previously found to be significantly associated with the 20-24 year male unemployment to total employment ratio. Results show that a dramatic reduction in Australian young male (aged 20-34 years) suicide has occurred since 1997-1998, declining from approximately 40 per 100,000 in 1997-1998 to approximately 20 per 100,000 in 2003. Most of the decline is due to a decrease in suicide by hanging and to a lesser extent from motor vehicle carbon monoxide and other gases. Further, the previously established strong secular association (lasting over 3 decades from 1966) between the rate ratio of 20-24 year male suicide to total (crude) male suicide, and the rate ratio of 20-24 year male unemployment to total unemployment, appears to have been disrupted. ARIMA modelling of the suicide ratio against the initiative indicates a highly significant statistical association between the NYSPS and the suicide ratio reduction but not between the NYSPS and the unemployment indicator trend, suggesting a break in the link between young male suicide and unemployment. The recent sudden turnaround in Australian young male suicide trends and its extent appears to preclude explanations centring on slow-moving social indices traditionally associated with suicide, or on possible cohort effects. This sudden decrease has occurred mainly in non-impulsive means, and at the same time has broken a long-standing secular link between 20 and 24-year-male suicide and unemployment, lending plausibility to the case for the NYSPS having had an impact on young male suicide in Australia.

Firearm related deaths: the impact of regulatory reform

OBJECTIVES

To examine trends in rates of firearm related deaths in Victoria, Australia, over 22 years in the context of legislative reform and describe and investigate impact measures to explain trends.

DESIGN

Mortality data were extracted from vital statistics for 1979-2000. Data on firearm related deaths that were unintentional deaths, assaults, suicides, and of undetermined intent were analyzed. Rates were calculated with population data derived from estimates by the Australian Bureau of Statistics. A quasi-experimental design that used a Poisson regression model was adopted to compare relative rates of firearm related deaths for Victoria and the rest of Australia over three critical periods of legislative reform. The Wilcoxon signed ranks test was used to assess changes in the types of firearm related deaths before and after 1998.

RESULTS

In Victoria, two periods of legislative reform related to firearms followed mass shooting events in 1988 and 1996. A national firearm amnesty and buyback scheme followed the latter. Victorian and Australian rates of firearm related deaths before reforms (1979-86) were steady. After initial Victorian reforms, a significant downward trend was seen for numbers of all firearm related deaths between 1988 and 1995 (17.3% in Victoria compared with the rest of Australia, p<0.0001). A further significant decline between 1997 and 2000 followed the later reforms. After the later all state legislation, similar strong declines occurred in the rest of Australia from 1997 (14.0% reduction compared with Victoria, p = 0.0372). Victorian reductions were observed in frequencies of firearm related suicides, assaults, and unintentional deaths before and after the 1988 reforms, but statistical significance was reached only for suicide.

CONCLUSION

Dramatic reductions in overall firearm related deaths and particularly suicides by firearms were achieved in the context of the implementation of strong regulatory reform.

Suicide in Australian farming, 1988-1997

OBJECTIVES

To identify and describe suicide data for occupational classifications relating to farm managers and agricultural labourers for Australia for the period 1988 to 1997, and to relate resultant suicide rates to farmers' terms of trade.

METHOD

Descriptive and linear regression analysis of aggregated mortality data.

RESULTS

In the period 1988 to 1997, 921 suicides were identified. The majority of these suicides were farm managers (67.4%). Farm manager suicides occurred predominantly in older age groups (55 + years). In comparison agricultural labourer suicides were younger, with the majority of suicides occurring in the 15-39 years age group. The most common methods for both groups were firearms (particularly hunting rifles and shot guns), hanging and motor vehicle exhaust gas. These methods accounted for approximately 81% of all male farm suicides. Firearms accounted for 51% of male farm suicide, in comparison to 23% for the wider Australian male population for the same period. Estimated age standardized rates per 100 000 for male farm managers for the 10-year period ranged from 24.8 to 51.4. For male agricultural labourers these rates ranged from 23.5 to 41.9. Analyses also revealed a negative correlation (r = -0.75, p < 0.01) between farm manager suicide rates and farmers' terms of trade.

CONCLUSION

Male farm manager and agricultural labourer suicide rates are higher than male national rates and rates in the wider rural population, particularly in the later years of the period investigated. Firearms prefigure as the most common method of suicide, despite decreases in this method in the wider rural population. Establishing more accurate denominator data for the farming community is a priority, as is preventative action that accounts for unique aspects of farm life.

Preventive interventions for youth suicide: a risk factor-based approach

OBJECTIVE

This review draws on current knowledge of risk for youth suicide to categorize strategies for intervention. Its goal is to identify areas of 'research need' and to provide an evidence base to identify 'best buy' preventive interventions for youth suicide.

METHOD

The design, development, implementation and evaluation of prevention strategies ranging from clinical interventions to population-based universal approaches are considered within five risk factor domains: individual, family, community, school and peer.

RESULTS

There is a paucity of evidence on the effects of interventions targeting depression and suicidal behaviour. Nevertheless, there are effective indicated, selective and universal interventions for important risk factors for depression and suicidal behaviour. Little evidence has emerged to support the efficacy of some traditional approaches to suicide prevention, such as school based suicide education programs and telephone hotlines.

CONCLUSIONS

Youth suicide prevention strategies in Australia have generally employed traditional approaches that focus on clinical interventions for self-harmers, restricting access to lethal means, providing services to high risk groups and enhancing general practitioner responses. Both program development and research evaluation of interventions for many important risk and protective factors for suicide have been neglected.

The epidemiology of suicide and attempted suicide among young Australians

OBJECTIVE

This paper summarises a report to the NHMRC the objectives of which were to review research into the epidemiology of youth suicide in Australia and identify gaps in research.

METHOD

Literature searches were conducted. A limited amount of new data analysis was included to shed light on reliability issues of official Australian suicide data.

RESULTS

The review examined suicide data systems, including issues to do with coroners, the Australian Bureau of Statistics and alternative systems. The epidemiological areas reviewed included: all ages, youth, age and gender, geographical, socioeconomic, marital, indigenous, migrants, suicides in custody and gay and lesbian suicides.

CONCLUSION

While much is known about the epidemiology of youth suicide, much remains to be clarified. Study of indigenous issues is perhaps the most neglected area; study of family issues may be potentially be the most productive.

Management of gunshot wounds at a Sydney teaching hospital

BACKGROUND

Injuries caused by firearms account for only a small percentage of trauma admissions and deaths in Australia but are frequently the subject of media and public attention. The present study examines the epidemiology and management of firearm injuries presenting to St Vincent's Hospital, which is located at the edge of the central business district of Sydney.

METHODS

The medical records of all patients presenting to St Vincent's with a gunshot wound (GSW) from January 1988 to December 1998 were analysed. Additional details were acquired from New South Wales State Coroner's Court reports and media archives, especially major newspapers.

RESULTS

Seventy-four patients presented to St Vincent's Hospital with 103 GSW. The age (mean +/- SD) was 31+/-11 years. Sixty-seven patients (91%) were male. Alcohol was identified as a factor in 24 cases (32%) while other drugs were indicated in four cases (5%). Ten patients (14%) had intentionally self-inflicted wounds, seven (9%) had accidental wounds and 57 (77%) had wounds that were caused by crime-related violence. Sixty patients (81%) underwent operation for their injury. Thirty complications were seen in 18 patients (24%). Eleven patients (15%) died. The length of hospital stay (mean +/- SEM) was 18+/-9 days.

CONCLUSIONS

The incidence of trauma due to firearms has not increased at St Vincent's hospital in the period 1988-98. Most GSW were inflicted in the setting of criminal violence, with a high proportion due to handguns. Patients were mostly young men, and alcohol or other drugs were frequently involved. Outcomes are comparable to other centres managing large volumes of penetrating trauma.

Suicide attempts by firearms and by leaping from heights: a comparative study of survivors

OBJECTIVE

The purpose of this study was to compare the clinical and demographic profiles of patients who deliberately harmed themselves, either by jumping from a great height or by using firearms, and survived.

METHOD

The study consisted of an 18-year retrospective case history analysis of survivors of jumping and shooting identified from the database of consultation-liaison psychiatry referrals at a hospital in Sydney, Australia. Clinical and demographic information was collated and analyzed.

RESULTS

Fifty-one patients who had shot themselves and 31 patients who had jumped, all of whom had survived, were assessed by the consultation-liaison psychiatry team. There were clear differences between the two groups. Those who jumped were more likely to be single, unemployed, and psychotic. Those who used firearms were more likely to be male, abuse alcohol, have a forensic history, and have an antisocial or borderline personality disorder.

CONCLUSIONS

In this study, the subjects who attempted suicide by shooting themselves and those who did so by jumping had different profiles of mental state, personality function, and psychiatric diagnosis. The importance of mental state and specific psychiatric diagnosis as determinants of the method used has been neglected in studies of suicide. These factors should be considered along with others such as accessibility and acceptability of means, since these differences may be important when suicide prevention is considered. It is also important for psychiatrists providing consultation-liaison services to be aware of these differences in order to ensure optimal treatment of survivors.

Access to methods of suicide: what impact?

OBJECTIVE

The aim of this paper is to explore the conceptual basis of limiting access to potential methods of suicide as a public health measure.

METHOD

A review of the literature was conducted.

RESULTS

Both physical availability and sociocultural acceptability are important determinants of choice. There is considerable evidence of an association between method availability and method specific suicide rates. There is also evidence that restriction of method availability is often associated with a reduction in method specific suicide rates. There is some evidence that restrictions on method availability under certain conditions may reduce overall suicide rates.

CONCLUSIONS

Suicide methods employed by young Australians are changing, with a disturbing rise in frequency of hanging and car exhaust suicides slightly offset by a decline in firearm suicides. Opportunities exist for further reducing firearm suicides and addressing exhaust suicides by practical measures. There are also obvious options for changing prescribing practices with respect to more lethal medications (e.g. tricyclic antidepressants). However, the rise in hanging seems problematic from this perspective and in need of ecological study.
