BACKGROUND:Assessing patient perspectives is fundamental to determining whether anti-racism and cultural training programs and services associated with an intervention achieve their intended outcomes, yet reviews frequently focus on health provider perspectives. This systematic review, therefore, aimed to investigate First Nations Peoples' experiences, as patients, of interventions to improve their Cultural Safety and experiences in secondary and tertiary healthcare settings. METHODS:American Psychological Association's PsycInfo (via EBSCOhost), Cumulative Index to Nursing and Allied Health Literature Complete (via EBSCOhost), PubMed, and Scopus (via Elsevier) were all searched from inception to 9 December 2025. Eligible intervention studies needed to report the experiences of First Nations' people as care recipients in secondary and tertiary healthcare settings. Eligible study countries were Australia, Canada, Aotearoa (New Zealand), and the United States of America (USA). General study quality was assessed using the Mixed Methods Appraisal Tool. Study quality was also examined with a modified version of the Aboriginal and Torres Strait Islander Quality Appraisal Tool to provide a First Nations perspective. Qualitative meta-aggregation was conducted to synthesize both qualitative and quantitative data. RESULTS:There were 22 reports (11 qualitative, 7 quantitative, and 4 mixed methods) of 20 eligible studies, including 2092 First Nations care recipients. Interventions and quantitative outcomes were heterogeneous, precluding meta-analysis. Four studies reported on cultural training for health professionals, with the remainder service-level interventions. The qualitative meta-aggregation resulted in six synthesized findings, which reflected the mechanisms by which these programs worked and their outcomes. Four synthesized findings described mechanisms. These included emotional and practical support; acknowledgement, respect, and support for culture; feeling accepted, heard, valued, safe, comfortable, and respected; and navigating treatment and the system. The two synthesized findings related to outcomes concerned perceptions of health services and, relatedly, impacts on health service access. Quality appraisal revealed no discussion of existing and newly created intellectual property considerations. Study limitations included undefined terminology, terms being used interchangeably, and a few studies from the USA and Aotearoa (New Zealand). CONCLUSIONS:Published intervention studies assessing First Nations care recipients' experiences appear to be increasing. Future interventions must clearly define the terminology in the intervention, use mixed-methods approaches, and report intellectual property considerations.

Objective: People with different psychiatric diagnoses use certain suicide methods more frequently. These findings could have implications for reducing suicide. Therefore, the aim of this study was to assess associations between three severe mental illnesses (SMIs) and suicide methods, while adjusting for other confounding factors that could influence choice of suicide methods.Methods: We used information on all individuals dying by suicide in Queensland, Australia, from 1989 to 2021. Methods were compared to hanging, strangulation and suffocation for people with three different SMIs with adjusted risk ratios in multinomial logistic regression models.Results: People with psychotic disorders were over three times more likely to jump from a high place, jump or lie before a moving object, or use a sharp object. They were also more than twice as likely to use explosive material or smoke, fire and flames; or drowning and submersion and 60% more likely to use crashing of a motor vehicle. Poisoning by drugs was around 50% higher in those with psychotic disorders or depression. No other methods were substantially elevated relative to hanging, strangulation and suffocation (HSS). People with bipolar and depression had a lower risk ratios (RR) for several suicide methods.Conclusion: People with psychotic disorders were the most likely to use diverse methods and would benefit the most from means restriction interventions. Trialling interventions to ensure that people with psychotic disorders can avoid situations where they could use these methods may reduce suicides in this group. Further analysis of what drugs people with depression and bipolar might use is needed.

The study aimed to examine the associations between experiences of racial discrimination within communities with suicide mortality rates for Aboriginal and Torres Strait Islander people. Age-standardised suicide rates (ASRs) were calculated using suicides recorded by the Queensland Suicide Register (QSR) of Aboriginal and Torres Strait Islander people in Queensland from 2009 to 2015. Rate Ratios (RRs) were used to compare ASRs in areas with high and low levels of reported discrimination, and other comparative community-level risk and protective factors (remoteness, socio-economic resources, and Indigenous language use). The age-standardised suicide rate was 31.74 deaths per 100 000 persons/year for Aboriginal and Torres Strait Islander people for the years 2009–2015. ASRs were significantly higher in areas where more of the First Nations residents experienced recent discrimination (RR = 1.33; 95

AIMS:Most information about the association between childhood maltreatment (CM) and subsequent psychiatric morbidity is based on retrospective self-reports. Findings from longitudinal studies using prospective reports to statutory agencies may be subject to attrition. We therefore compared the prevalence to age 30 of inpatient psychiatric diagnoses in those who experienced agency-reported CM with those of the rest of the cohort using administrative data to minimise loss to follow-up. METHODS:We used linked administrative data for two birth cohorts of all individuals born in Queensland, Australia in 1983 and 1984 (N = 83,050) and followed to age 30 years. This was the entire cohort aside from 312 people who died. Information on CM came from statewide child protection data and psychiatric diagnoses from all public and private hospital admissions in Queensland. RESULTS:On adjusted analyses, the 4,703 participants (5.7%) who had been notified to the statewide child protection authority had three to eight times the odds of being admitted for any of the following psychiatric diagnoses by age 30 years old: schizophrenia-spectrum disorders, bipolar affective disorders, depression, anxiety and post-traumatic stress disorders (PTSD). There were similar findings for all the CM subtypes. Associations were especially strong for PTSD with between a seven - and nine-fold increase in the odds of admission. CONCLUSIONS:This is one of the largest studies of the long-term effects of CM, covering an entire jurisdiction. All types of maltreatment are significantly related to a range of psychiatric disorders requiring hospitalisation. Early identification, intervention and providing appropriate support to individuals who have experienced CM may help mitigate the long-term consequences and reduce the risk of subsequent mental health problems.

Background: The current study aimed to compare current suicide rates, trends, previous treatment, suicidality and mental health diagnoses for First Nations and non-Indigenous young people who died by suicide. Methods: Age-specific suicide rates (ASSRs) were calculated per 100,000 persons/year using suicides aged 10-19 years in the Queensland Suicide Register. Rate Ratios (RRs) and 95 % CIs compared ASSRs for First Nations and non-Indigenous youth dying by suicide in Queensland, Australia, from 2001 to 2018. Risk ratios (RiskR) with 95 % CIs compared characteristics between First Nations and non-Indigenous youth suicides. Joinpoint regression was used to identify any changes in trends and annual percentage change (APC) in suicides with 95 % CIs. Results: The First Nations youth ASSR was 24.71 deaths per 100,000 persons/year, 4.5 times the non-Indigenous ASSR (95 % CI = 3.74-5.38, p < 0.001). Both non-Indigenous and First Nations suicide trends were stable with no joinpoints (APC: 0.3 %, 95 % CI: -1.6-2.2, p = 0.78; APC: 0.9 %, 95 % CI: -0.2-2.1, p = 0.11). Less than a quarter (23.9 %) of First Nations young people had ever received mental health treatment, significantly fewer than non-Indigenous youth (RiskR = 0.80, 95 % CI = 0.71-0.90, p < 0.001). Similarly, in the three months preceding their death, only 14.5 % of First Nations young people had received mental health treatment (RiskR = 0.89, 95 % CI = 0.83-97, p = 0.015). Limitations: Reported mental illness, suicidality and help-seeking could be underreported due to concealment from family or police. Conclusions: The current study finds no change in the gap between the First Nations and Non-Indigenous youth suicide rates nor evidence of decrease in the First Nations youth suicide rate. There is a need for alternative approaches to Indigenous youth suicide prevention, such as assertive outreach models outside of traditional triage and mental health systems to proactively build trusting relationships with young people in communities to identify young people needing support.

Background Child maltreatment is a major public health issue worldwide. Retrospective studies show a strong association between self-reported child maltreatment and poor mental and physical health problems. Prospective studies that use reports to statutory agencies are less common, and comparisons of self- and agency-reported abuse in the same cohort even rarer. Aims This project will link state-wide administrative health data with prospective birth cohort data ( N = 7223) from Brisbane in Queensland, Australia (including notifications to child protection agencies), to compare psychiatric outcomes in adulthood of agency- and self-reported child maltreatment while minimising attrition bias. Method We will compare people with all forms of self- and agency-reported child maltreatment to the rest of the cohort, adjusting for confounding in logistic, Cox or multiple regression models based on whether outcomes are categorical or continuous. Outcomes will be hospital admissions, emergency department presentations or community/out-patient contacts for ICD-10 psychiatric diagnoses, suicidal ideation and self-harm as recorded in the relevant administrative databases. Conclusions This study will track the life course outcomes of adults after having experienced child maltreatment, and so provide an evidence-based understanding of the long-term health and behavioural consequences of child maltreatment. It will also consider health outcomes that are particularly relevant for adolescents and young adults, especially in relation to prospective notifications to statutory agencies. Additionally, it will identify the overlap and differences in outcome for two different sources of child maltreatment identification in the same cohort.

Suicides are likely to be underreported. In Australia, the National Coronial Information System (NCIS) provides information about suicide deaths reported to coroners. The NCIS represents the findings on the intent of the deceased as determined by coroners. We used the Queensland Suicide Register (QSR) to assess the direction, magnitude, and predictors of any differences in the reporting of suicide in Queensland. Therefore, we conducted a consecutive case series study to assess agreement and variation between linked data from the NCIS and QSR determinations of suicide for all suicide deaths (N = 9520) in the QSR from 2001 to 2015 recorded from routinely collected coronial data. The rate of concordance between the QSR and NCIS for cases of intentional self-harm was 92.7%. There was disagreement between the findings in the data, since 6.3% (n = 597) were considered as intentional self-harm in the QSR but not in the NCIS, and, less commonly, 0.9% (n = 87) were considered intentional self-harm in the NCIS but not in the QSR. Overall, the QSR reported 510 more suicides than the NCIS in 15 years. These findings indicate that using suicide mortality data from suicide registers may not underreport suicide as often.

Objective Some countries have implemented systems to monitor suicides in real-time. These systems differ because of the various ways in which suicides are identified and recorded. The main objective of this study was to conduct an international comparison of major real-time suicide mortality surveillance systems to identify joint strengths, challenges, and differences, and thereby inform best-practice criteria at local, national, and international levels. Methods Five major real-time suicide mortality surveillance systems of various coverage levels were identified and selected for review via an internet-based scoping exercise and prior knowledge of existing systems. Key information including the system components and practices was collated from those organizations that developed and operate each system using a structured template. The information was narratively and critically synthesized to determine similarities and differences between the systems. Results The comparative review of the five established real-time suicide surveillance systems revealed more commonalities than differences overall. Commonalities included rapid, routine surveillance based on minimal, provisional data to facilitate timely intervention and postvention efforts. Identified differences include the timeliness of case submission and system infrastructure. Conclusion The recommended criteria could promote replicable components and practices in real-time suicide surveillance while offering flexibility in adapting to regional/local circumstances and resource availability.

Background: In Australia, most state-based suicide registers now publicly release suicide mortality data alongside those the Australian Bureau of Statistics (ABS) releases annually. Aims: This study compared ABS's recorded suicides with three state-based suicide registers (Queensland, Victoria, and Tasmania). We compared their case definitions and coding approaches to assist users in choosing the most suitable data source and interpret differences between sources. Method: We collated the number of suicides by year of registration and occurrence (2006-2020). We compared the scope and coding of suicides between ABS and the registers using publicly available suicide reports and data releases. Results: The ABS's annual suicide numbers are similar to (and in Tasmania exceed) the numbers reported by state-based registers. The ABS year of occurrence data diverges substantially from the Victoria and Queensland register data in 2020, perhaps attributable to ongoing ABS revision processes. Minimal overlap exists between the case definitions and coding practices of the ABS and registers. Limitations: This is not an individual-level concordance study. Conclusion: Despite different case definitions and coding practices, the two sources produced largely consistent data. They have complementary strengths: timeliness (suicide register data) and enabling cross-jurisdictional comparisons (ABS data).

Background Severe mental illness (SMI) is associated with significant morbidity. Frailty combines biological ageing, comorbidity and psychosocial factors and can predict adverse health outcomes. Emerging evidence indicates that frailty is higher in individuals with SMI than in the general population, although studies have been limited by sample size. Aims To describe the prevalence of frailty in people with SMI in a large cohort using three different frailty measures and examine the impact of demographic and sociodemographic variables. Method The UK Biobank survey data, which included individuals aged 37–73 years from England, Scotland and Wales from 2006 to 2010, with linked in-patient hospital episodes, were utilised. The prevalence of frailty in individuals with and without SMI was assessed through three frailty measures: frailty index, physical frailty phenotype (PFP) and Hospital Frailty Risk Score (HFRS). Stratified analysis and dichotomous logistic regression were conducted. Results A frailty index could be calculated for 99.5% of the 502 412 UK Biobank participants and demonstrated greater prevalence of frailty in women and an increase with age. The prevalence of frailty for those with SMI was 3.19% (95% CI 3.0–3.4), 4.2% (95% CI 3.8–4.7) and 18% (95% CI 15–23) using the frailty index, PFP and HFRS respectively. The prevalence ratio was between 3 and 18 times higher than in those without SMI. Conclusions As a measure, frailty captures the known increase in morbidity associated with SMI and may potentially allow for earlier identification of those who will benefit from targeted interventions.

Surveillance is a crucial part of suicide prevention, for identifying suicide trends, risk groups, suicide clusters (World Health Organization (WHO), 2014) and frequently used locations for suicide. Suicide sites are usually public, natural or man-made objects known for their use for suicidal behaviour (e.g. bridges or cliffs) (Ross et al., 2020). Some suicide prevention activities to prevent jumping at common sites are more effective than others. For example, a 2020 systematic review found that physical barriers reduced jumping suicides by 93% compared to a 46% reduction for jumping means restriction interventions delivered in combination with other interventions (Okolie et al., 2020). Furthermore, a recent economic analysis of installing barriers at bridge sites in Australia found that barriers installed at multiple bridge sites are cost-saving and cost-effective in the short term (5 years) and long term (10 years) (Bandara et al., 2022). The Story Bridge is a heritage-listed 74-m-high bridge in Brisbane City across the Brisbane River. Suicides from the Story Bridge have received attention over many years and preventive actions have been recommended (e.g. Law et al., 2014). After the media attention on Story Bridge murder-suicides in 2011 and 2012, the interim Queensland Suicide Register (iQSR), a real-time surveillance system, showed that suicides at the site increased from 7 in 5 years (2006– 2010) to 16 in 2012 alone. Informed by the Australian Institute for Suicide Research and Prevention, in consultation with Queensland Health and Brisbane City Council, the Story Bridge Suicide Prevention Reference Group was established and different preventive actions were adopted, including installing Lifeline phones and surveillance cameras in 2012 and barriers at the Story Bridge by December 2015. This analysis examines the impact of these activities on suicides from the Story Bridge and the potential substitution effect by comparing changes in nearby locations.

BackgroundPredicted increases in suicide were not generally observed in the early months of the COVID-19 pandemic. However, the picture may be changing and patterns might vary across demographic groups. We aimed to provide a timely, granular picture of the pandemic's impact on suicides globally.MethodsWe identified suicide data from official public-sector sources for countries/areas-within-countries, searching websites and academic literature and contacting data custodians and authors as necessary. We sent our first data request on 22nd June 2021 and stopped collecting data on 31st October 2021. We used interrupted time series (ITS) analyses to model the association between the pandemic's emergence and total suicides and suicides by sex-, age- and sex-by-age in each country/area-within-country. We compared the observed and expected numbers of suicides in the pandemic's first nine and first 10-15 months and used meta-regression to explore sources of variation.FindingsWe sourced data from 33 countries (24 high-income, six upper-middle-income, three lower-middle-income; 25 with whole-country data, 12 with data for area(s)-within-the-country, four with both). There was no evidence of greater-than-expected numbers of suicides in the majority of countries/areas-within-countries in any analysis; more commonly, there was evidence of lower-than-expected numbers. Certain sex, age and sex-by-age groups stood out as potentially concerning, but these were not consistent across countries/areas-within-countries. In the meta-regression, different patterns were not explained by countries’ COVID-19 mortality rate, stringency of public health response, economic support level, or presence of a national suicide prevention strategy. Nor were they explained by countries’ income level, although the meta-regression only included data from high-income and upper-middle-income countries, and there were suggestions from the ITS analyses that lower-middle-income countries fared less well.InterpretationAlthough there are some countries/areas-within-countries where overall suicide numbers and numbers for certain sex- and age-based groups are greater-than-expected, these countries/areas-within-countries are in the minority. Any upward movement in suicide numbers in any place or group is concerning, and we need to remain alert to and respond to changes as the pandemic and its mental health and economic consequences continue.FundingNone.

Background There are widespread concerns that the COVID-19 pandemic may increase suicides. Few studies have analysed effects beyond the pandemic's early months or examined changes in known suicide risk factors. Methods Using time series models fit with Poisson regression, we analysed monthly police-reported suicides in Ecuador from January 2015 to June 2021. Treating March 2020 as the start of the pandemic, we calculated rate ratios (RRs) comparing the observed to the expected number of suicides for the total population and by age and sex groups. We investigated changes in risk factors, precipitants, geographic distribution, and suicide methods. Findings There was no evidence that suicide rates were higher than expected during the pandemic (RR 0 center dot 97 [95% CI 0 center dot 92-1 center dot 02]). There was some evidence of fewer than expected male suicides (RR 0 center dot 95 [95% CI 0 center dot 90-1 center dot 00]). The proportion of suicides occurring in urban and coastal areas increased but decreased amongst indigenous and other minorities. The proportions of suicides with evidence of alcohol consumption, disability, and amongst married and cohabiting individuals decreased, whereas suicides where mental health problems were considered contributory increased. There were relative increases in the proportion of suicides by hanging but decreases in self-poisoning and other suicide methods. Interpretation The pandemic did not appear to adversely impact overall suicide numbers nationwide during the first 16 months of the pandemic. Reduced alcohol consumption may have contributed to the decline in male suicides. Copyright (c) 2022 The Authors. Published by Elsevier Ltd.

To characterise the demographic and clinical characteristics of women who died by suicide in the perinatal period to inform and improve suicide prevention strategies. Retrospective analysis of maternal suicides during and within 1 year after the end of pregnancy in Queensland between January 2004 and December 2017. Outcomes measured included timing of death in relation to pregnancy, sociodemographic and clinical characteristics and health service use prior to death. There were 65 deaths by suicide in the study period; six occurred during pregnancy, 30 occurred after a live birth, 22 occurred after a termination of pregnancy and seven followed a miscarriage or stillbirth. Most suicides were late maternal deaths. Women were younger, and more likely to identify as Aboriginal or Torres Strait Islander, when compared to all women giving birth for the same time period. Most women had a prior mental health diagnosis, most commonly depression. Over half of women had recent relationship separation or conflict prior to death. Perinatal women had higher rates of death by violent means than all women in Queensland who died by suicide during the same time period. The demographic, psychosocial and clinical characteristics of a group of women who died by suicide have been described, and this shows a high proportion of women with a prior mental health diagnosis. To reduce maternal mortality, psychosocial screening must be implemented broadly and continued until the end of the first year postpartum. Similar screening attention is needed for women who had a termination of pregnancy, miscarriage or stillbirth.

Farmers are at higher risk of suicide than other occupations and the general population. The complex suicide risk factors have not been examined in a large, population-wide study across a significant time period. This observational study draws on existing data from the United States' National Violent Death Reporting System (NVDRS), including 140,523 farming- or non-farming-related suicide decedents between 2003 and 2016 from across 40 states. "Farming-related" decedents included 2,801 suicides. Farmers had higher odds of being male, older, less well-educated, and American Indian/Alaska Native. Farmers had higher odds of using firearms and-when farmers used a gun-higher odds of using a long-arm weapon. Farmers had lower odds of having a known mental health condition or job problem, and lower odds of having made a previous suicide attempt or leaving a suicide note. Findings highlight the complexity of suicide risk within the context of farming in the United States and reinforce the need for tailored prevention efforts; employing means restriction of firearms; and emphasizing that traditional risk factors may not be as common in the farming population.

Objective: The study aimed to examine associations of community cultural connectedness with Aboriginal and Torres Strait Islander young peoples' suicide rates in areas with elevated risk factors. Methods: Age-specific suicide rates (ASSRs) were calculated using suicides recorded by the Queensland Suicide Register (QSR) of Aboriginal and Torres Strait Islander young people (aged 15-24 years) in Queensland from 2001-2015. Rate Ratios (RRs) compared young peoples' suicide rates in areas with high and low levels of cultural connectedness indicators (cultural social capital and Indigenous language use) within areas with elevated risk factors (high rates of discrimination, low socioeconomic resources, and remoteness). Results: Within low socioeconomically resourced areas and where Aboriginal and Torres Strait Islander people experienced more discrimination, greater engagement and involvement with cultural events, ceremonies and organisations was associated with 36% and 47% lower young peoples' suicide rates respectively (RR=1.57, 95%CI=1.13-2.21, p=<0.01; RR=1.88, 95%CI=1.25-2.89, p=<0.01). Within remote and regional areas, higher levels of community language use was associated with 26% lower suicide rates (RR=1.35, 95%CI=1-1.93, p=0.04), and in communities experiencing more discrimination, language use was associated with 34% lower rates (RR=1.53, 95%CI=1.01-2.37, p=0.04). Conclusion: Cultural connectedness indicators were associated with lower Aboriginal and Torres Strait Islander young peoples' suicide rates in communities experiencing the most disadvantage. Implications for public health: This provides initial evidence for trialling and evaluating interventions using cultural practices and engagement to mitigate against the impacts of community risk factors on Aboriginal and Torres Islander suicide.

Aims: We aimed to determine whether there has been a change in the number of suicides occurring in three Australian states overall, and in age and sex subgroups, since the COVID-19 pandemic began, and to see if certain risk factors for suicide have become more prominent as likely underlying contributing factors for suicide.Method: Using real-time data from three state-based suicide registers, we ran multiple unadjusted and adjusted interrupted time series analyses to see if trends in monthly suicide counts changed after the pandemic began and whether there had been an increase in suicides where relationship breakdown, financial stressors, unemployment and homelessness were recorded.Results: Compared with the period before COVID-19, during the COVID-19 period there was no change in the number of suicides overall, or in any stratum-specific estimates except one. The exception was an increase in the number of young males who died by suicide in the COVID-19 period (adjusted RR 1.89 [95% CI 1.11-3.23]).The unadjusted analysis showed significant differences in suicide in the context of unemployment and relationship breakdown during the COVID-19 compared to the pre-COVID-19 period. Analysis showed an increase in the number of suicides occurring in the context of unemployment in the COVID-19 period (unadjusted RR 1.53 [95% CI 1.18-1.96]). In contrast, there was a decrease in the number of suicides occurring in the context of relationship breakdown in the COVID-19 period (unadjusted RR 0.82 [95% CI 0.67-0.99]). However, no significant changes were identified when the models were adjusted for possible over-dispersion, seasonality and non-linear trend.Conclusion: Although our analysis found no evidence of an overall increase in suicides after the pandemic began, the picture is complex. The identified increase in suicide in young men indicates that the impact of the pandemic is likely unevenly distributed across populations. The increase in suicides in the context of unemployment reinforces the vital need for mitigation measures during COVID-19, and for ongoing monitoring of suicide as the pandemic continues.
