Suicidal and self-harm presentations to Emergency Departments: The challenges of identification through diagnostic codes and presenting complaints
Mental Disorders and Communication of Intent to Die in Indigenous Suicide Cases, Queensland, Australia
In comparing Indigenous to non-Indigenous suicide in Australia, this study focussed on the frequency of the association between some psychiatric conditions, such as depression and alcohol abuse, and some aspect of suicidality, in particular communication of suicide intent. Logistic regression was implemented to analyze cases of Indigenous (n = 471) versus non-Indigenous suicides (n = 6,655), using the Queensland Suicide Register as a data source. Compared to non-Indigenous suicides, Indigenous cases had lower odds of being diagnosed with unipolar depression, seeking treatment for psychiatric conditions or leaving a suicide note. Indigenous suicides had greater odds of verbally communicating suicide intent and having a history of alcohol and substance use. The magnitude of these differences is remarkable, underscoring the need for culturally sensitive suicide prevention efforts
Examining adult-onset offending: a case for adult cautioning
This paper argues that extending formal police cautioning to include first-time, less serious adult-onset offenders is a cost-effective strategy that would enable scarce criminal justice resources to be redirected to provide evidence-based interventions for more serious and prolific offenders who present an ongoing risk of offending.
Foreword
Very little is known about adult-onset offenders. This makes it difficult to know the most effective way for the criminal justice system to respond to these offenders. This project examined the nature of adult-onset offending in the 1983ā84 Queensland Longitudinal Data Cohort and explored whether adult cautioning may be a suitable and cost-effective alternative to current court processing. Half of all offenders in this cohort started offending in adulthood (between 18 and 25 years), however, most adult-onset offenders had just one or two relatively less serious officially recorded offences. The authors argue that extending formal police cautioning to include first-time, less serious adult-onset offenders is a cost-effective strategy that would enable scarce criminal justice resources to be redirected to provide evidence-based interventions for more serious and prolific offenders who present an ongoing risk of offending
Suicidal Presentations to Emergency Departments in a Large Australian Public Health Service over 10 Years
This paper presents trends and characteristics for 32,094 suicidal presentations to two Emergency Departments (EDs) in a large health service in Australia across a 10-year period (2009–2018). Prevalence of annual suicidal presentations and for selected groups of consumers (by sex, age groups, and ethnicity) was determined from a machine learning diagnostic algorithm developed for this purpose and a Bayesian estimation approach. A linear increase in the number of suicidal presentations over 10 years was observed, which was 2.8-times higher than the increase noted in all ED presentations and 6.1-times higher than the increase in the population size. Females had higher presentation rates than males, particularly among younger age groups. The highest rates of presentations were by persons aged 15–24. Overseas-born persons had around half the rates of suicidal presentations than Australian-born persons, and Indigenous persons had 2.9-times higher rates than non-Indigenous persons. Of all presenters, 70.6% presented once, but 5.7% had five or more presentations. Seasonal distribution of presentations showed a peak at the end of spring and a decline in winter months. These findings can inform the allocation of health resources and guide the development of suicide prevention strategies for people presenting to hospitals in suicidal crisis

Efficacy of the Zero Suicide framework in reducing recurrent suicide attempts: cross-sectional and time-to-recurrent-event analyses
Who uses firearms as a means of suicide? A population study exploring firearm accessibility and method choice
<p>Abstract</p> <p>Background</p> <p>The 1996 Australian National Firearms Agreement introduced strict access limitations. However, reports on the effectiveness of the new legislation are conflicting. This study, accessing all cases of suicide 1997-2004, explores factors which may impact on the choice of firearms as a suicide method, including current licence possession and previous history of legal access.</p> <p>Methods</p> <p>Detailed information on all Queensland suicides (1997-2004) was obtained from the Queensland Suicide Register, with additional details of firearm licence history accessed from the Firearm Registry (Queensland Police Service). Cases were compared against licence history and method choice (firearms or other method). Odds ratios (OR) assessed the risk of firearms suicide and suicide by any method against licence history. A logistic regression was undertaken identifying factors significant in those most likely to use firearms in suicide.</p> <p>Results</p> <p>The rate of suicide using firearms in those with a current license (10.92 per 100,000) far exceeded the rate in those with no license history (1.03 per 100,000). Those with a license history had a far higher rate of suicide (30.41 per 100,000) compared to that of all suicides (15.39 per 100,000). Additionally, a history of firearms licence (current or present) was found to more than double the risk of suicide by any means (OR = 2.09, <it>P </it>< 0.001). The group with the highest risk of selecting firearms to suicide were older males from rural locations.</p> <p>Conclusion</p> <p>Accessibility and familiarity with firearms represent critical elements in determining the choice of method. Further licensing restrictions and the implementation of more stringent secure storage requirements are likely to reduce the overall familiarity with firearms in the community and contribute to reductions in rates of suicide.</p
Suicide in the absence of mental disorder? A review of psychological autopsy studies across countries
Background: While numerous past reviews of psychological autopsy (PA) studies have examined the relationship between mental disorder and suicide, there has been little systematic investigation of suicide occurring in the absence of any identifiable psychiatric condition. Aim: This article reviews available literature on the topic by considering Axis I, sub-threshold, mild disorders and personality disorders. Method: We conducted a systematic review of PA studies from 2000 onwards. Studies included in the review had to clearly describe the proportion of suicide cases without a classifiable mental disorder or sub-threshold condition. Results: Up to 66.7% of suicide cases remained without diagnosis in those studies that only examined Axis I disorders (n = 14). Approximately 37.1% of suicide cases had no psychiatric condition in research papers that assessed personality and Axis I disorders (n = 9), and 37% of suicides had no Axis I, sub-threshold/mild conditions (n = 6). In general, areas in China and India had a higher proportion of suicides without a diagnosis than studies based in Europe, North America or Canada. Conclusion: Variation in the proportion of suicide cases without a psychiatric condition may reflect cultural specificities in the conceptualization and diagnosis of mental disorder, as well as methodological and design-related differences between studies.Griffith Health, Australian Institute for Suicide Research & PreventionNo Full Tex
