Suicides in Aboriginal and non-Aboriginal people following hospital admission for suicidal ideation and self-harm: A retrospective cohort data linkage study from the Northern Territory.

PURPOSE: This study aimed to explore risk factors for suicide in Aboriginal and non-Aboriginal people following hospital admission for suicidal ideation and self-harm in the Northern Territory, Australia to help clarify opportunities for improved care and intervention for these population groups. METHODS: Individuals with at least one hospital admission involving suicidal ideation and/or self-harm between 1 July 2001 and 31 December 2013 were retrospectively recruited and followed up using linked mortality records to 31 December 2014. Survival analyses stratified by Indigenous status identified socio-demographic and clinical characteristics from index hospital admissions associated with suicide. RESULTS: Just over half of the 4391 cohort members identified as Aboriginal (n = 2304; 52.4%). By 2014, 281 deaths were observed comprising 68 suicides, representing a 2.6% and 2.0% probability of suicide for Aboriginal and non-Aboriginal people, respectively. After adjusting for other characteristics, a higher risk of suicide was associated with male sex (Aboriginal adjusted hazard ratio: 4.14; 95% confidence interval: [1.76, 9.75]; non-Aboriginal adjusted hazard ratio: 5.96; 95% confidence interval: [1.98, 17.88]) and repeat hospital admissions involving self-harm (Aboriginal adjusted hazard ratio: 1.37; 95% confidence interval: [1.21, 1.55]; non-Aboriginal adjusted hazard ratio: 1.29; 95% confidence interval: [1.10, 1.51]). Severe mental disorders were associated with a four times higher risk of suicide (adjusted hazard ratio: 4.23; 95% confidence interval: [1.93, 9.27]) in Aboriginal people only. CONCLUSION: The findings highlight non-clinical risk factors for suicide that suggest the need for comprehensive psychosocial assessment tailored to Aboriginal and non-Aboriginal people hospitalised with suicidal ideation or self-harm. Implementing appropriate management and aftercare within a broader public health framework is needed to support recovery and reduce long-term suicide risk in the community, especially for Aboriginal people and males.

Delivery of preventive health services to Indigenous adults: response to a systems-oriented primary care quality improvement intervention.

OBJECTIVE: To describe changes in delivery of preventive services among adults in Aboriginal communities that occurred in association with a systems-oriented intervention. DESIGN, SETTING AND PARTICIPANTS: A quality improvement intervention with a 2-year follow-up was undertaken at 12 Aboriginal community health centres in the Northern Territory between January 2002 and December 2005. The study involved 360 well adults aged 16-49 years who had no known diagnosis of chronic disease. INTERVENTION: Two annual cycles of assessment, feedback workshops, action planning, and implementation of system changes. Assessment included a structured review of health service systems and an audit of clinical records. MAIN OUTCOME MEASURES: Adherence to guideline-scheduled preventive services including taking basic measurements, laboratory investigations, lifestyle counselling and pneumococcal vaccination. RESULTS: Of 12 preventive services measured, delivery of four services showed improvement over the study period: counselling on diet increased from 3% to 8% (P = 0.018); counselling on physical activity from 2% to 8% (P = 0.006); counselling on smoking from 2% to 11% (P = 0.003); and counselling on alcohol from 2% to 10% (P = 0.007). There was no improvement in important measures such as monitoring of waist circumference, blood pressure and blood glucose level, and delivery of pneumococcal vaccination. CONCLUSION: Our systems-oriented intervention was associated with some improvement in counselling activities, but no significant improvement in delivery of other preventive services. The main reason may be that implementation focused more on chronic illness management than preventive services for generally well adults.

Aboriginal health workers and diabetes care in remote community health centres: a mixed method analysis.

OBJECTIVE: To assess the effect of employing Aboriginal health workers (AHWs) on delivery of diabetes care in remote community health centres, and to identify barriers related to AHWs' involvement in diabetes and other chronic illness care. DESIGN, SETTING AND PARTICIPANTS: Three-year follow-up study of 137 Aboriginal people with type 2 diabetes in seven remote community health centres in the Northern Territory. MAIN OUTCOME MEASURES: Delivery of guideline-scheduled diabetes services; intermediate outcomes (glycated haemoglobin [HbA(1c)] and blood pressure levels); number and sex of AHWs at health centres over time; barriers to AHWs' involvement in chronic illness care. RESULTS: There was a positive relationship between the number of AHWs per 1000 residents and delivery of guideline-scheduled diabetes services (but not intermediate health outcomes). Presence of male AHWs was associated with higher adherence to the guidelines. Barriers to AHWs' involvement in chronic illness care included inadequate training, lack of clear role divisions, lack of stable relationships with non-Aboriginal staff, and high demands for acute care. CONCLUSIONS: Employing AHWs is independently associated with improved diabetes care in remote communities. AHWs have potentially important roles to play in chronic illness care, and service managers need to clearly define and support these roles.

A multifaceted health-service intervention in remote Aboriginal communities: 3-year follow-up of the impact on diabetes care.

OBJECTIVE: To examine the trends in processes of diabetes care and in participant outcomes after an intervention in two remote regions of Australia. DESIGN: Follow-up study over 3 years. SETTING: Seven health centres in the Tiwi Islands and the Katherine West region of the Northern Territory. PARTICIPANTS: 137 Aboriginal people with type 2 diabetes. INTERVENTION: Implementation of a multifaceted trial, including transfer of purchasing and planning responsibility to local health boards, the development and dissemination of clinical guidelines supported by electronic registers, recall and reminder systems and associated staff training, and audit and feedback. MAIN OUTCOME MEASURES: Trends in the proportion of Aboriginal people receiving services in accordance with clinical guidelines and in the proportion for whom specified levels of blood pressure and glycosylated haemoglobin (HbA(1c)) were achieved; health staff perceptions of barriers to effective service delivery. RESULTS: An initial improvement in overall service levels from 40% to 49% was not fully sustained over the 3-year period. The overall proportion of services delivered varied from 22% to 64% between communities and over time. The proportion of participants whose most recent HbA(1c) level was less than 7% improved from 19% to 32%, but there was little change in blood pressure control. Perceived barriers to service delivery included discontinuities in staffing, lack of work-practice support and patients' acceptance of services. CONCLUSIONS: Multifaceted interventions can improve quality of care in this environment, but achieving sustainable, high-quality care in a range of services and local conditions presents particular challenges. Developing and testing strategies for consistent and sustained improvement should be a priority for service providers and researchers.
