RESUMO
OBJECTIVES: To determine the numbers and types of medicines dispensed around the time of death to people who die by suicide; to compare the medicines recently dispensed and those recorded in post mortem toxicology reports. DESIGN, SETTING, PARTICIPANTS: Analysis of linked National Coronial Information System (NCIS) and Pharmaceutical Benefits Scheme (PBS) data from the Australian Suicide Prevention using Health Linked Data (ASHLi) study, a population-based case series study of closed coronial cases for deaths of people in Australia aged ten years or more during 1 July 2013 - 10 October 2019 deemed by coroners to be the result of intentional self-harm. MAIN OUTCOME MEASURES: Proportions of people to whom medicines were dispensed around the time of death, by medicine group, class, and specific medicine; comparison of medicines recently dispensed and those detected by post mortem toxicology. RESULTS: Toxicology reports were available for 13 541 of 14 206 people who died by suicide (95.3%; 10 246 men, 75.7%); poisoning with medicines contributed to 1163 deaths (8.6%). At least one PBS-subsidised medicine had been dispensed around the time of death to 7998 people (59.1%). For three medicine classes, the proportions of people in whom the medicines were detected post mortem and their death was deemed medicine-related were larger for those without records of recent dispensing than for people for whom they had been dispensed around the time of death: antidepressants (17.7% v 12.0%), anxiolytics (16.3% v 14.8%), and sedatives/hypnotics (24.3% v 16.5%). At least one recently dispensed medicine not detected post mortem was identified for 6208 people (45.8%). CONCLUSIONS: A considerable proportion of people who died by suicide were not taking psychotropic medicines recently dispensed to them, suggesting non-adherence to pharmacotherapy, and a smaller than expected proportion were using antidepressants. Conversely, medicines that had not recently been dispensed were detected post mortem in many people for whom poisoning with medicines was a contributing factor, suggesting medicine stockpiling.

OBJECTIVES: To examine healthcare utilisation patterns in a sample of young people with self-reported experiences of self-harm and/or suicidal behaviours. METHODS: A national survey examining mental health in a nationally representative sample of young Australians aged 12-17 years, linked to routinely collected healthcare and dispensing data. For respondents that self-reported experience of self-harm, suicidal ideation, suicidal plan and/or suicide attempt, we assessed attendance at a Medicare Benefits Scheme (MBS) subsidised MH service or non-MH general practitioner (GP) attendance at three time periods: 1) ever, 2) in the 12 months prior to completing the survey and 3) after completing the survey until 31 Dec 2015. We also assessed correlates associated with attendance and non-attendance at a MH service. RESULTS: The study included 311 young people. MH services were attended in the 12 months before the survey by 38.3% with attempted suicide, 28.7% with a suicidal plan, 28.9% with suicidal ideation and 29.4% with self-harm. MH treatment administered by a GP was the most common MH service (25%); followed treatment by psychologist (15%) and psychiatrist (5%). Attendance at a MH service was observed highest alongside more severe self-reported depression. CONCLUSIONS: Potential underutilisation of MBS MH services by young people with self-harm and/or suicidal behaviours.

The barriers to opioid use in some countries necessitate the need to identify suitable alternatives or adjuncts for pain relief. The gabapentinoids (gabapentin and pregabalin) are approved for the management of persistent pain in adults, but not in children. Searches were conducted in Embase, Medline, Scopus, and Web of Science up until November 2017, for randomized controlled trials that investigated the analgesic effects of gabapentin or pregabalin in children and adolescents <18 years of age. A total of 7 publications were identified, 5 regarding gabapentin as prophylactic postsurgical pain relief for either adenotonsillectomy (n = 3) or scoliosis surgery (n = 2), and 1 for gabapentin treatment of chronic regional pain syndrome/neuropathic pain. One study investigated the efficacy of pregabalin as a treatment for fibromyalgia. Based on the studies' primary outcomes alone, neither of the chronic pain studies involving gabapentin and pregabalin showed significant efficacy compared with amitriptyline or placebo, respectively. Two of the prophylactic gabapentin studies for adenotonsillectomy and idiopathic scoliosis surgery reported significantly fewer children requiring analgesia and lower opioid requirement, respectively, compared with placebo. Two of the identified clinical trials (conducted by the same first author) on the efficacy of gabapentin for prophylactic postadenotonsillectomy pain relief were omitted from narrative synthesis due to clear evidence of fabricated data. Overall, this review identified a paucity of evidence for the analgesic effect and safety of gabapentinoids in children. We also suggest audit of any current evidence-based practice and clinical guidelines that have cited the research studies with fabricated data.

ISSUE ADDRESSED: This study aimed to develop a working checklist for university alcohol policies and apply this checklist to current policies in universities in New South Wales (NSW), Australia. METHODS: We developed a working checklist of possible university alcohol policy approaches, drawn from the World Health Organization's alcohol policy recommendations, university alcohol policy research from the United States and norms and expectations currently incorporated in Australian university alcohol policies. We then conducted a content analysis of university alcohol policies in NSW, Australia, based on this checklist. All NSW university websites were searched for any policies or guidelines related to alcohol. The content of each policy or guideline was assessed in terms of whether it satisfied the various components of the checklist. RESULTS: All 11 universities in NSW have an alcohol policy, and these policies are readily available and accessible online. There were two main themes identified in the aims across documents: maximising health and safety of individuals and protecting the university as an institutional entity. Inclusiveness and safety were the predominant themes that satisfied policy content. No document incorporated methods for monitoring/evaluating policy impact. CONCLUSIONS: University alcohol policies that incorporated both individual-level and population-based approaches to alcohol harm reduction were more likely to score higher on the checklist. However, this analysis highlighted many opportunities to strengthen policies by increasing their comprehensiveness and incorporating means to evaluate their effectiveness. SO WHAT?: We present a working checklist that can be used for future research and policy development, regarding university alcohol policies and guidelines.

AIMS: This study investigates paediatric drug dosage guidelines with the aim of investigating their agreement with body surface area (BSA) scaling principles. METHODS: A total of 454 drug dosage guidelines listed in the AMH-CDC 2015 were examined. Data extracted included the administration, frequency and dose per age bracket from 0 to 18 years. Drug treatments were categorized as follows: (1) The same dose recommendation in milligrams per kilogram (mg kg-1 ) for all age/weights; (2) Change in the mg kg-1 dosing according to age/weight; (3) Change in dose in mg according to age/weight; (4) Change from mg kg-1 dosing to a dose in mg according to age/weight; (5) The same recommendation for all age/weight groups in mg; or (6) BSA dosing. Example drugs were selected to illustrate dose progression across ages. RESULTS: Most drug treatments (63%) have the same mg kg-1 dose for all age/weight groups, 14% are dosed in mg kg-1 across all ages with dose changes according to age/weight, 13% were dosed in mg across all ages with dose changes, 10% switched from mg kg-1 to a set dose in mg, 4.2% have the same dose in mg for all age and weight groups and 2.2% are dosed according to BSA. CONCLUSIONS: Paediatric dosage guidelines are based on weight-based formulas, available dosing formulations and prior patterns of use. Substantial variation from doses predicted by BSA scaling are common, as are large shifts in recommended doses at age thresholds. Further research is required to determine if better outcomes could be achieved by adopting biologically based scaling of paediatric doses.

OBJECTIVE: Investigating diurnal variation in the timing of suicidal behaviours offers opportunity to better understand its various proximal risk factors. Acute use of alcohol is a potent proximal risk factor for suicidal behaviour, though the nature of this risk is poorly understood. The aim of this study was to compare the diurnal variation in time of poison ingestion between deliberate self-poisonings that involve alcohol versus those that do not. METHODS: A retrospective analysis of consecutive presentations to a toxicology service following deliberate self-poisoning, 1996-2016. An independent samples Kolmogorov-Smirnov test was performed to test the null hypothesis that the diurnal distribution of poison ingestion time was equal across self-poisonings that did and did not involve alcohol co-ingestion. Presence of circadian rhythmicity was established using cosinor analysis. RESULTS: A total of 11,088 deliberate self-poisoning records, for 7467 patients (60.8% females), were included in the analysis. In all, 31.3% of the total records involved alcohol co-ingestion. Distribution of exposure time was significantly different between deliberate self-poisonings that did and did not involve alcohol ( p < 0.001). The alcohol co-ingestion group showed a significantly greater prominent peak with poisoning occurring later in the evening (~20:00 hours) compared to poisonings that did not involve alcohol (~18:00 hours). CONCLUSION: This study exposed the differential diurnal patterns in deliberate self-poisoning according to the presence of alcohol co-ingestion. This analysis adds to the accumulating evidence that suicidal behaviour that involves alcohol co-ingestion represents a distinct subtype, which may be driven by alcohol consumption patterns in society. This also means that this large proportion of deliberate self-poisonings may not otherwise have occurred if it were not for alcohol consumption, underscoring the importance of drug and alcohol services for alcohol-related self-harm.

BackgroundAcute alcohol consumption is a major risk factor for suicide, therefore investigating factors associated with alcohol-related self-harm warrant attention.AimsTo investigate the influence of prescribed psychotropic medications on the odds of co-ingesting alcohol preceding or during intentional efforts to self-poison.MethodA cross-sectional analysis of consecutive hospital presentations following intentional self-poisoning was conducted. A total of 7270 patients (4363 women) aged 18-96 were included.ResultsThe odds of alcohol co-ingestion were increased in those not prescribed any medication (odds ratio (OR) = 1.27, 99% CI 1.10-1.46, P<0.001) and in impulsive self-poisonings (OR = 1.39, 99% CI 1.11-1.74, P<0.001). Odds were decreased in those prescribed anticonvulsants (OR = 0.69, 99% CI 0.51-0.93), antipsychotics (OR = 0.55, 99% CI 0.45-0.66) and antidepressants (OR = 0.87, 99% CI 0.77-0.99).ConclusionsFindings indicate that being medicated for a psychiatric illness may reduce the likelihood of alcohol consumption during times of acute distress, hence perhaps may reduce the risk of intentional self-poisoning.

OBJECTIVE: Information on the rates and predictors of polypharmacy of central nervous system medication in older people with intellectual disability is limited, despite the increased life expectancy of this group. This study examined central nervous system medication use in an older sample of people with intellectual disability. METHODS: Data regarding demographics, psychiatric diagnoses and current medications were collected as part of a larger survey completed by carers of people with intellectual disability over the age of 40 years. Recruitment occurred predominantly via disability services across different urban and rural locations in New South Wales and Victoria. Medications were coded according to the Monthly Index of Medical Specialties central nervous system medication categories, including sedatives/hypnotics, anti-anxiety agents, antipsychotics, antidepressants, central nervous system stimulants, movement disorder medications and anticonvulsants. The Developmental Behaviour Checklist for Adults was used to assess behaviour. RESULTS: Data were available for 114 people with intellectual disability. In all, 62.3% of the sample was prescribed a central nervous system medication, with 47.4% taking more than one. Of those who were medicated, 46.5% had a neurological diagnosis (a seizure disorder or Parkinson's disease) and 45.1% had a psychiatric diagnosis (an affective or psychotic disorder). Linear regression revealed that polypharmacy was predicted by the presence of neurological and psychiatric diagnosis, higher Developmental Behaviour Checklist for Adults scores and male gender. CONCLUSION: This study is the first to focus on central nervous system medication in an older sample with intellectual disability. The findings are in line with the wider literature in younger people, showing a high degree of prescription and polypharmacy. Within the sample, there seems to be adequate rationale for central nervous system medication prescription. Although these data do not indicate non-adherence to guidelines for prescribing in intellectual disability, the high rate of polypharmacy and its relationship to Developmental Behaviour Checklist for Adults scores reiterate the importance of continued medication review in older people with intellectual disability.

BACKGROUND: Comorbid risky alcohol use in bipolar disorder (BD) is recognized for its high prevalence and clinical relevance, though understanding of its neurobiological underpinning is limited. The N-methyl-D-aspartate (NMDA) receptor has recognized alterations in BD and is a major site of ethanol's effects in the brain. The present study aimed to examine the NMDA receptor system in adolescents and young adults with BD by evaluating the longitudinal changes in a robust marker of NMDA function, mismatch negativity (MMN), in relation to changes in alcohol use patterns. METHODS: Forty-six BD patients (aged 16-30) were recruited at baseline and 59% (n = 27) returned for follow-up 17.9 +/- 7.3 months later. At both time-points a two-tone, passive, duration-deviant MMN paradigm was conducted and alcohol measures were collected. Pearson's correlations were performed between changes in MMN amplitudes and changes in alcohol use. Multiple regression was used to assess whether MMN amplitudes at baseline could predict alcohol use at follow-up. RESULTS: Reduction in risky drinking patterns was associated with increased temporal MMN and decreased fronto-central MMN. Larger temporal MMN at baseline was a significant predictor of greater alcohol use at follow-up. CONCLUSIONS: Results suggest risky alcohol use in BD may further compound pre-existing NMDA receptor abnormalities and, importantly, reducing alcohol use early in stages of illness is associated with changes in MMN. This highlights the importance of monitoring alcohol use from first presentation. In addition, preliminary results present an exciting potential for utility of MMN as a neurobiological marker used to determine risk for alcohol misuse in BD.

Importance: Determining the association between drug use and suicide is complicated but can help to inform targeted suicide prevention strategies. Objective: To examine the substances prevalent in poisoning- and nonpoisoning-related suicides in Australia. Design, Setting, and Participants: This was a multiple-year, cross-sectional study of suicides from July 2013 to October 2019 in Australia with toxicology data available in a national coronial database. The cause of death was classified as poisoning related if any type of poisoning was determined by the coroner to contribute to the cause of death. Prevalence ratios (PRs) were calculated to compare substance detection in poisoning- vs nonpoisoning-related suicides. Data were analyzed from October 2021 to April 2023. Exposures: All substances detected in decedents at the time of death according to toxicology reports were recorded. Main Outcome(s) and Measure(s): The most common individual substances and substance classes were identified. From these, blood concentrations of substances of interest were analyzed, and the most commonly occurring combinations of substance classes were listed. Results: Toxicology was performed on 13â¯664 suicide decedents (median [IQR] age, 44 [31-57] years; 10â¯350 male [76%]). From these, 3397 (25%) were poisoning-related suicides (median [IQR] age, 50 [38-63] years; 2124 male [63%]). The remainder were classified as nonpoisoning-related suicides (median [IQR] age, 42 [29-55] years; 8226 male [80%]). PRs for common medicine classes being detected in poisoning-related suicides compared with nonpoisoning-related suicides were as follows: antidepressants (PR, 1.63; 95% CI, 1.54-1.73), benzodiazepines (PR, 2.01; 95% CI, 1.90-2.13), nonopioid analgesics/anti-inflammatory drugs (PR, 1.88; 95% CI, 1.78-2.00), and opioids (PR, 2.72; 95% CI, 2.58-2.87). Alcohol (as ethanol ≥0.03 g/100 mL) was almost equally prevalent in poisoning- and nonpoisoning-related deaths (PR, 1.07; 95% CI, 1.01-1.14), whereas amphetamines (PR, 0.68; 95% CI, 0.61-0.77) and cannabinoids (PR, 0.67; 95% CI, 0.60-0.74) were detected more often in nonpoisoning-related suicides. Combinations of multiple sedative agents in poisoning-related suicides were common. Conclusions and Relevance: Both poisoning- and nonpoisoning-related suicide deaths featured a high prevalence of psychotropic medicines or potential intoxication, which suggests the association of suicide with poor mental health and substance misuse. Findings suggest that substances with a high involvement in poisoning-related suicides should be prescribed cautiously, including antidepressants that are toxic in overdose, sedatives, opioids, and potentially lethal combinations.

Aims: We investigated the association between problematic use of alcohol and/or drugs (PUAD) and the incidence, urgency, and mode of discharge for a subsequent episode of self-harm (SH) or suicidal ideation (SI). Methods: This was a retrospective population-based cohort study of individuals admitted to hospital for an index episode of SH/SI (2010-2014) using linked data from hospital admissions and emergency department (ED) presentations. The outcome variables were (1) subsequent presentation to the ED for SH/SI, (2) triage category, and (3) mode of departure. Key predictors were PUAD. Results: In total, 23,007 individuals were admitted to hospital for an index SH/SI, of whom 8% had a subsequent presentation to an ED for SH/SI within a year. The odds of subsequent presentation was increased in those with problematic alcohol use (AOR 1.62, 95% CI 1.36, 1.92), drug use (AOR 1.28, 95% CI 1.07, 1.53), and mental health diagnoses (AOR 1.63, 95% CI 1.44, 1.85). Those with problematic alcohol use were more likely to be assigned to the most urgent triage categories (AOR 1.84, 95% CI 1.32, 2.56). Limitations: Defining SH and PUAD using administrative data is challenging, and the true prevalence is likely to be underestimated. Conclusion: The findings underscore the importance of drug health intervention as a key component of self-harm prevention.

Background: Suicide prevention requires a shift from relying on an at-risk individual to engage with the healthcare system. Understanding patterns of healthcare engagement by people who have died by suicide may provide alternative directions for suicide prevention. Methods: This is a population-based case-series study of all suicide decedents (n = 3895) in New South Wales (NSW), Australia (2013-2019), with linked coronial, health services and medicine dispensing data. Healthcare trajectories were identified using a k-means longitudinal 3d analysis, based on the number and type of healthcare contacts in the year before death. Characteristics of each trajectory were described. Findings: Five trajectories of healthcare utilisation were identified: (A) none or low (n = 2598, 66.7%), (B) moderate, predominantly for physical health (n = 601, 15.4%), (C) moderate, with high mental health medicine use (n = 397, 10.2%), (D) high, predominantly for physical health (n = 206, 5.3%) and E) high, predominantly for mental health (n = 93, 2.4%). Given that most decedents belonged to Trajectory A this suggests a great need for suicide preventive interventions delivered in the community, workplace, schools or online. Trajectories B and D might benefit from opioid dispensing limits and access to psychological pain management. Trajectory C had high mental health medicine use, indicating that the time that medicines are prescribed or dispensed are important touchpoints. Trajectory E had high mental health service predominantly delivered by psychiatrists and community mental health, but limited psychologist use. Interpretation: Although most suicide decedents made at least one healthcare contact in the year before death, contact frequency was overall very low. Given the characteristics of this group, useful access points for such intervention could be delivered through schools and workplaces, with a focus on alcohol and drug intervention alongide suicide awareness. Funding: Australia's National Health and Medical Research Council.
RESUMO
INTRODUCTION: Meta-analyses show antidepressant initiation has increased risk of suicidal behavior <25 years, no difference 25-64 years and reduced risk 65+ years. Estimating risks from RCTs has limitations and real-world population estimates are uncommon. METHODS: A self-controlled case series reporting incidence rate ratio (IRR) between exposed and control periods for antidepressants associated with suicide attempt, in Australian older age adults. We included all cases with suicide attempt [hospital data for ICD codes (X60-X84)] and any antidepressant use (n = 689) by participants in the "45 and Up Study". RESULTS: For all antidepressants the IRR for suicide attempt was elevated across all exposures, declining from 7.44 (95%CI 5.57-9.94) during the first 30 days, to 2.21 (1.73-2.81) at 91+ days. All four antidepressant sub-groups had higher IRRs for the first 30 day exposure: 2.43 (1.37-4.29) for TCAs, 4.06 (2.78-5.93) for SSRIs, 4.15 (2.65-6.50) for other antidepressants, and 4.92 (3.30-7.34) for SNRIs. Increased IRR persisted for 61- to 90-day exposures for SSRIs 2.42 (1.18-4.98) and SNRIs 2.66 (1.34-5.27). CONCLUSION: Some older adults have increased risk of suicide attempt with antidepressant exposure, which may persist for months. Clinical guidelines should recommend a period of monitoring for treatment-emergent suicidal thoughts and behaviors in older adult patients.

BACKGROUND: Alcohol consumption is related to both suicidal ideation and behaviour, but evidence regarding the effect of psychological interventions to reduce alcohol use on self-harm, suicidal behaviour and ideation is limited. Therefore, the aim of the current study was to conduct a systematic literature review and meta-analysis of the effect of alcohol-related psychological interventions on these outcomes at the individual level. METHODS: We searched the Cochrane CENTRAL, Cochrane DARE, EMBASE, Medline, ProQuest, PsycINFO, PubMed, SCOPUS, and Web of Science electronic databases to 5 January 2021. We included all English-language papers worldwide utilising psychological interventions with a focus on harmful alcohol use and suicidal ideation, self-harm, and/or suicidal behaviour. RESULTS: We identified 11 studies, nine provided sufficient numerical data for meta-analysis. Although the methods and effect sizes varied substantially in the studies, reducing alcohol may led to a reduction in self-harm and suicide attempt by the final follow-up assessment (Odds ratio [OR] 0.57, 95% confidence interval [CI] 0.33 to 0.97, 6 studies, 491 participants, I2 = 0%). However, there was no apparent effect for these interventions on suicidal ideation or suicide deaths. There was no significant difference in effect by therapeutic approach. Neither intervention dose (in hours) nor duration (in months) significantly explained differences in treatment effectiveness. CONCLUSIONS: Interventions targeting harmful alcohol consumption may contribute towards a reduction in self-harm at the individual level. However, there was no apparent effect of these interventions on suicidal ideation (measured either continuously or dichotomously) or suicide deaths.

Importance: Suicide is a major and preventable cause of death worldwide. Means restriction aims to reduce the rate of completed suicides by limiting public access to lethal suicide methods. Means restriction of agents used in poisoning is more controversial because there is potential to switch to other lethal methods. Objective: To identify the changes in suicide rate by the targeted poison and the corresponding changes in suicide by other methods. Evidence Review: Five databases (MEDLINE, Embase, Scopus, PsycInfo, and Web of Science) were searched for studies on national means restriction of poison that were published in the English language from inception until December 31, 2019. Of the 7657 articles that were screened by title and abstract, 62 studies were included in the analysis. Findings: Sixty-two studies from 26 countries in Europe, the US, Australia, Asia, and the United Kingdom were included in the review. The studies included restrictions on pesticides (15 countries), domestic gas (14 countries), motor vehicle exhaust (9 countries), and pharmaceuticals (8 countries). The median (IQR) change in method-specific suicide rates was -1.18 (-2.03 to -0.46) per 100 000 people after restrictions, whereas the median (IQR) change in other methods of suicide (not the restricted poison) was -0.09 (-2.22 to 1.65) per 100 000 people. Decreases in suicide by the restricted poison were not associated with increases in suicide by other methods. An estimated 57 355 poison-specific suicides annually (before the interventions were implemented) may have benefited the most from means restriction. Conclusions and Relevance: This systematic review found that means restriction of poison was associated with decreased method-specific suicide rates without an equivalent shift toward the use of other methods. Suicide prevention strategies need to address both individuals who are at risk and population-level policies.

BACKGROUND: The acute effects of alcohol consumption are a major risk factor for suicide. Positive blood alcohol concentrations are present in almost one-third of all suicides at time of death. These suicides are defined as alcohol-related suicides. This cross-sectional study examines the geospatial distribution/clustering of high proportions of alcohol-related suicides and reports on socioeconomic and demographic risk factors. METHODS: National Coronial Information System (NCIS) data were used to calculate proportions of suicides with alcohol present at the time of death for each level 3 statistical areas (SA3) in Australia. A density analysis and hotspot cluster analysis were used to visualise and establish statistically significant clustering of areas with higher (hotspots) and lower (coldspots) proportions. Subsequently, socioeconomic and demographic risk factors for alcohol use and suicide were reported on for hot and cold spots. RESULTS: Significant clustering of areas with higher proportions of alcohol-related suicide occurred in northern Western Australia, the Northern Territory and Queensland, as well as inland New South Wales and inland Queensland. Clustering of SA3s with significantly lower proportions occurred in major city and inner regional Sydney and Melbourne. Conclusion and implications for public health: Results from this study identify areas in which prevention strategies should target alcohol use and can be used to inform prevention strategy design. Additionally, hotspots and coldspots identified in this study can be used for further analysis to better understand contextual risk factors for alcohol-related suicide.

AIM: To describe the assignment of International Classification of Disease (ICD)-10 alcohol codes as underlying or contributory causes of death by the Australian Bureau of Statistics during mortality coding for suicides according to the blood alcohol concentration (BAC) detected at autopsy. DESIGN: Population-based case-series descriptive analysis. SETTING AND PARTICIPANTS: Data for all alcohol-related (Alc+) suicide deaths (aged 15+) in Australia from 2010-2015 (n = 3132) from the National Coronial Information System. MEASUREMENTS: Alc+ suicides were categorised as those with a post-mortem BAC ≥0.05 g/100 mL. The outcome variable was whether the case was assigned an ICD-10 alcohol code (F10.0-F10.9, R78.0, T51, X45 and/or X65). We estimated OR for the assignment of codes in Alc+ suicides using BAC as the key predictor. We also examined several covariates that have been implicated in the risk of Alc+ suicides. FINDINGS: An ICD-10 alcohol code was assigned during the mortality coding process in 47.6% (n = 1491) of Alc+ suicides. Higher BAC was associated with higher odds of having a code assigned; cases with a BAC over 0.20 g/100 mL over were twice as likely to have an alcohol code assigned (adjusted OR [AOR] = 2.06, 95% CI = 1.59, 2.67) compared with cases with a BAC of 0.050-0.075 g/100 mL. Compared with New South Wales, higher likelihood of code assignment was found in Northern Territory (AOR = 3.85, 95% CI = 2.32, 6.63) and Western Australia (AOR = 2.89, 95% CI = 2.27, 3.68). Compared with 15-24 year olds, 25-44 (AOR = 0.79, 95% CI = 0.63, 0.99) and 65-84 year olds (AOR = 0.63, 95% CI = 0.43, 0.93) were less likely to have a code assigned. CONCLUSIONS: An ICD-10 alcohol code was not assigned as an underlying or contributory cause of death in over half of suicides in Australia (2010-2015) with a BAC ≥0.05 g/100 mL. The higher the BAC detected at autopsy, the more likely cases were to be assigned an alcohol code during the mortality coding process.

Deliberate self-harm and suicide affect all age groups, sexes, and regions, and their prevention is a global health priority. Acute alcohol misuse and chronic alcohol misuse are strong, modifiable risk factors, and Internet interventions aiming to reduce alcohol misuse and comorbid mental health problems (e.g., depression) are a promising and effective treatment modality. The research team aimed to evaluate the feasibility and effectiveness of an Internet-based comorbidity intervention primarily aiming to reduce alcohol consumption, and secondarily to reduce readmission for deliberate self-harm and improve psychological outcomes among people hospitalized for deliberate self-harm who also engage in problematic alcohol use. However, due to several barriers to recruitment, the trial could not be completed and was discontinued. The authors present a "Lessons Learned" discussion and describe the Internet Intervention for Alcohol Improvement (iiAIM) trial, discuss the key barriers experienced by the research team, and recommend potential solutions that may help future trials in this area.

Alcohol consumption has been found to be related to suicidal behavior at the individual and population level, but there is lack of literature reviews on the effect of alcohol policies on suicidal behavior. Therefore, the aim of the current study is to conduct a systematic literature review of the impact of alcohol policies at the population level on suicidal behavior and ideation. We searched the Cochrane CENTRAL, Cochrane DARE, EMBASE, Medline, ProQuest, PsycINFO, PubMed, SCOPUS, and Web of Science electronic databases in March 2019. Papers analyzing alcohol policies limiting alcohol use and studying suicidal behaviors as an outcome measure were included; we identified 19 papers. Although the methods and effect sizes varied substantially in the studies, reducing alcohol often led to reduction in suicidal behavior. Ecological-level studies predominantly investigated the effect of restrictions on alcohol availability and increased cost of alcohol, and the majority presented a reduction in suicides across Western and Eastern Europe, as well as the US. The majority of studies were rated as unclear risk of bias for a number of domains due to a lack of clear reporting. Policies targeting harmful alcohol consumption may contribute towards a reduction in suicidal behavior at the population level.
