Suicide and mortality following self-harm in Culturally and Linguistically Diverse communities in Victoria, Australia: insights from a data linkage study.

ABSTRACT:

Background

While cultural backgrounds are well-documented to be relevant to intentional self-harm, little is known about how cultural and linguistically diverse (CALD) backgrounds affect mortality outcomes following self-harm.

Aim

This study aimed to compare the risk of all-cause mortality and suicide after intentional hospital admissions for self-harm among people from CALD (vs. non-CALD) backgrounds.

Method

Linked hospital and mortality data in Victoria, Australia, was used to assess suicide and all-cause death after hospital admissions for self-harm among patients aged 15+ years. All-cause death was identified by following up on 42,122 self-harm patients (hospitalized between 01 July 2007 and 30 June 2019) until death or 15 February 2021. Suicide death was evaluated in 16,928 self-harm inpatients (01 January 2013 and 31 December 2017) until death or 28 March 2018. Cox regression models were fitted to compare mortality outcomes in self-harm patients from CALD vs. non-CALD backgrounds.

Outcomes

During the follow-up periods, 3,716 of 42,122 (8.8%) participants died by any cause (by 15 February 2021), and 304 of 16,928 (1.8%) people died by suicide (by 28 March 2018). Compared to the non-CALD group, CALD intentional self-harm inpatients had a 20% lower risk of all-cause mortality (HR: 0.8, 95% CI: 0.7-0.9) and a 30% lower risk of suicide (HR: 0.7, 95% CI: 049-0.97). Specifically, being from North Africa/Middle East and Asian backgrounds lowered the all-cause mortality risk; however, the suicide risk in Asians was as high as in non-CALD people.

Conclusion

Overall, people from CALD backgrounds exhibited lower risks of all-cause mortality and suicide following hospital admission for self-harm compared to the non-CALD group. However, when comparing risks based on regions of birth, significant variations were observed. These findings underscore the importance of implementing culturally tailored background-specific suicide preventive actions. The study focussed on outcomes following hospital admission for self-harm and did not capture outcomes for cases of self-harm that did not result in hospital admission. This limits generalisability, as some CALD people might avoid accessing healthcare after self-harm due to cultural factors. Future research that not limited to hospital data is suggested to build on the results.

Project description:BackgroundIn developed economies, obesity prevalence is high within children from some culturally and linguistically diverse (CALD) backgrounds. This study aims to identify whether CALD groups in Victoria, Australia, are at increased risk of childhood overweight and obesity, and obesity-related dietary behaviours; compared to their non-CALD counterparts.MethodsObjective anthropometric and self-report dietary behavioural data were collected from 2407 Grade 4 and 6 primary school children (aged 9-12 years). Children were categorised into CALD and non-CALD cultural groups according to the Australian Standard Classification of Languages. Overweight/obesity was defined according to the World Health Organization growth reference standards. Obesity-related dietary behaviour categories included excess consumption of takeaway foods, energy-dense, nutrient-poor snacks and sugar sweetened beverages. T-tests and chi-square tests were performed to identify differences in weight status and dietary behaviours between CALD and non-CALD children. Logistic regression analyses examined the relationship between CALD background, weight status and dietary behaviours.ResultsMiddle-Eastern children had a higher overweight/obesity prevalence (53.0%) than non-CALD children (36.7%; p < 0.001). A higher proportion of Middle-Eastern children had excess consumption of takeaway foods (54.9%), energy-dense, nutrient-poor snacks (36.6%) and sugar sweetened beverages (35.4%) compared to non-CALD children (40.4, 27.0 and 25.0%, respectively; p < 0.05). Southeast Asian and African children were 1.58 (95% CI = [1.06, 2.35]) and 1.61 (95% CI = [1.17, 2.21]) times more likely, respectively, to consume takeaway foods at least once per week than non-CALD children.ConclusionsDisparities in overweight/obesity prevalence and obesity-related dietary behaviours among children in Victoria suggest the need for cultural-specific, tailored prevention and intervention strategies.

Project description:ObjectiveTo explore the psychological, social and financial outcomes of COVID-19-and the sociodemographic predictors of those outcomes-among culturally and linguistically diverse communities in Sydney, Australia.DesignCross-sectional survey informed by the Framework for Culturally Competent Health Research conducted between March and July 2021.SettingParticipants who primarily speak a language other than English at home were recruited from Greater Western Sydney, New South Wales.Participants708 community members (mean age: 45.4 years (range 18-91)). 88% (n=622) were born outside of Australia, 31% (n=220) did not speak English well or at all, and 41% (n=290) had inadequate health literacy.Outcome measuresThirteen items regarding COVID-19-related psychological, social and financial outcomes were adapted from validated scales, previous surveys or co-designed in partnership with Multicultural Health and interpreter service staff. Logistic regression models (using poststratification weighted frequencies) were used to identify sociodemographic predictors of outcomes. Surveys were available in English or translated (11 languages).ResultsIn this analysis, conducted prior to the 2021 COVID-19 outbreak in Sydney, 25% of the sample reported feeling nervous or stressed most/all of the time and 22% felt lonely or alone most/all of the time. A quarter of participants reported negative impacts on their spousal relationships as a result of COVID-19 and most parents reported that their children were less active (64%), had more screen time (63%) and were finding school harder (45%). Mean financial burden was 2.9/5 (95% CI 2.8 to 2.9). Regression analyses consistently showed more negative outcomes for those with comorbidities and differences across language groups.ConclusionCulturally and linguistically diverse communities experience significant psychological, social and financial impacts of COVID-19. A whole-of-government approach is needed to support rapid co-design of culturally safe support packages in response to COVID-19 and other national health emergencies, tailored appropriately to specific language groups and accounting for pre-existing health disparities.

Project description:BackgroundThis study explored the experiences of people from culturally and linguistically diverse (CALD) backgrounds in Greater Western Sydney, Australia, in selected livelihood items during COVID-19 and the perceived impacts of the pandemic on their lives.MethodsA cross-sectional survey was used to collect data between 25 August and 30 September 2020 among CALD communities in Greater Western Sydney. Information was collected on respondents' experiences in selected livelihood items, including housing, finances, safety, accessing social services and activities, finding work, food, clothing, and relationships during COVID-19 and the pandemic's perceived impact on their lives. Descriptive and non-parametric statistics were used to analyze the data.ResultsOne hundred and ninety-eight participants were included in the study, 45.5% male and 54.5% female. Many respondents reported their experience in the selected livelihood items as "worse" during COVID-19 at the time of the study. The feeling of safety was most disrupted, with 56% of respondents rating their experience as "worse". This experience was followed by accessing social support group activities, with 50% of respondents stating their experience of using this service had worsened. The experience of accessing social services and financial situation was rated as "worse" by 41% of respondents. Experience in finding work, housing, and attending schools were all rated as "worse". The median perceived impact of COVID-19 among respondents who rated their experience in the selected livelihood items as "worse" were statistically higher than those who rated their experience as the "same". Respondents' characteristics also predicted the perceived impact of COVID-19. Unemployed respondents were 3.53 (95% CI: 1.16-10.73, p = 0.026) times more likely to perceive the impact of COVID-19 on their lives as "high" compared to employed respondents.ConclusionsThe finding demonstrates that the "high" number of respondents had the same situation as before COVID-19 and highlights the level of resilience exhibited by CALD communities in the Australian context. It also suggests that services in Australia were good during the pandemic. However, enhanced policy and initiatives designed to meet the CALD population's needs are required, particularly in the areas most reported to have been disrupted by changes associated with COVID-19.

Project description:ObjectiveThe majority of suicide decedents have had contact with health services close to their death. Some of these contacts include admissions to hospitals for physical and mental health conditions, injury and intentional self-harm. This study aims to establish and quantify the risks of suicide following hospital admission for a range of mental and physical illnesses.MethodsA retrospective analysis was carried out on existing morbidity and mortality data in Victoria. Data was extracted from the Victorian Admitted Episodes Dataset and the Victorian Suicide Register. Unplanned hospital admissions among adult patients (> = 15 years of age), discharged between 01 January 2011 and 31 December 2016 (2,430,154 admissions), were selected. Standardised Mortality Ratios were calculated for conditions with at least five linked suicides within one year of discharge from hospital.ResultsForty-three conditions defined at the three-digit level of the International Statistical Classification of Diseases and Related Health Problems 10th Revision, were associated with at least five subsequent suicides (within one year of hospital discharge); 14 physical illnesses, 5 symptoms, signs and abnormal clinical and laboratory findings, 12 mental health conditions, and 12 types of injury and poisonings. The highest Standardised Mortality Ratios were for poisonings (range; 27.8 to 140.0) and intentional self-harm (78.8), followed by mental health conditions (range; 15.5 to 72.9), symptoms, signs and abnormal clinical and laboratory findings (range; 1.4 to 43.2) and physical illnesses (range; 0.7 to 4.9).ConclusionsHospital admissions related to mental health conditions and injury and poisonings including self-harm were associated with a greater risk of suicide than physical conditions. Mental health conditions such as depressive episodes, personality disorders and psychotic episodes, injuries caused by intentional-self-harm and poisonings by certain types of drugs, carbon monoxide and hormones such as insulin can be prioritised for targeting suicide prevention initiatives for persons discharged from hospitals.

Project description:BackgroundEngagement frameworks provide the conceptual structure for consumer engagement in healthcare decision making, but the level to which these frameworks support culturally and linguistically diverse (CALD) consumer engagement is not known.ObjectiveThis study aimed to investigate how consumer engagement is conceptualised and operationalized and to determine the implications of current consumer engagement frameworks for engagement with CALD consumers.MethodAltheide's document analysis approach was used to guide a systematic search, selection and analytic process. Australian Government health department websites were searched for eligible publicly available engagement frameworks. A narrative synthesis was conducted.ResultsEleven engagement frameworks published between 2007 and 2019 were identified and analysed. Only four frameworks discussed engagement with CALD consumers distinctly. Organisational prerequisites to enhance engagement opportunities and approaches to enable activities of engagement were highlighted to improve CALD consumers' active participation in decision making; however, these largely focused on language, with limited exploration of culturally sensitive services.ConclusionThere is limited discussion of what culturally sensitive services look like and what resources are needed to enhance CALD consumer engagement in high-level decision making. Health services and policy makers can enhance opportunities for engagement with CALD consumers by being flexible in their approach, implementing policies for reimbursement for participation and evaluating and adapting the activities of engagement in collaboration with CALD consumers.Patient/public contributionThis study is part of a wider 'CanEngage' project, which includes a consumer investigator, and is supported by a consumer advisory group. The study was conceived with inputs from the consumer advisory group, which continued to meet regularly with the project team to discuss the methodology and emerging findings.
