There is opportunity for universities to actively engage with Aboriginal communities to participate, conduct and ideally lead responsible research that attends to community priorities and issues. The Health from the Grassroots (Grassroots) project sought to address an ongoing mismatch between university-defined and community-defined priorities in rural northern New South Wales (NSW), Australia. Grassroots, led by Aboriginal staff of the University Centre for Rural Health (UCRH), aimed at engaging Aboriginal communities in conversations to inform research priorities. The Grassroots project was a true representation of collaborative research led by and for Aboriginal people. The team designed a local survey conducted yarning sessions with community members and used this information to visualize report findings. Community members were highly engaged in the consultation process and the "rich picture" continues to be used to further conversations about evolving health and research priorities. The Aboriginal research team identified strengths and challenges faced by communities and health services in the region and centred community in decision-making for project design and direction. Challenges encountered include limited resources and time for team members to devote to the project outside of their substantive paid positions. This paper describes the project vision, implementation, and research team lessons in the first years. Meaningful consultation to inform research action arose from the team's deep-rooted relationships and identities as members of the community in which we live and work. Research priorities identified through the Grassroots project have been integrated into the ongoing work of the UCRH. [ABSTRACT FROM AUTHOR]

Finding Your Way is a shared decision-making resource created with and for Aboriginal People in New SouthWales, Australia, in 2021. It is the only culturally adapted shared decision-making resource for Aboriginal People in Australia and one of few examples developed with First Nations people internationally. A two-round modified e-Delphi approach, incorporating yarning techniques, was used to gather expert opinions and reach a consensus on the capabilities (knowledge and skills) required to effectively use Finding Your Way and engage in shared decision-making with Aboriginal People. A set of 29 predefined capabilities were gleaned from the research evidence and a yarning session, forming the basis of the e-Delphi process. In total, 138 panel members completed Round 1 of the e-Delphi process between January 19, 2023 and January 27, 2023, and 113 completed Round 2 between February 9, 2023 and February 20, 2023. The panel member retention rate was 82% across the two e-Delphi rounds, and the consensus threshold was 75% strongly agree for each capability. Consensus was reached for 10 capabilities, and a learning map was developed to reflect Aboriginal ways of valuing, being, knowing and doing as represented in the 8 Aboriginal Ways of Learning: Aboriginal Pedagogy framework (New South Wales Department of Education, n. d.). Cultural imagery was used to create the learning map to present the foundational knowledge and skills required to use Finding Your Way in a symbolic and non-linear way. The results signal the importance of navigating two worlds--working through Aboriginal knowledge and processes to generate cultural responsiveness and safety at the intersection of traditional cultural knowledge and the Western paradigm of shared decision-making.

Type 2 diabetes mellitus is an established health problem for Indigenous Australians. One strategy to address this issue is to educate health professionals in diabetes management and education. Objective The objective of this paper is to identify important issues that compromise the clinical practice of rural and remote Aboriginal health workers ( AHWs) and registered nurses ( RNs) who undertook an accredited Australian Diabetes Educators Association diabetes course and to suggest strategies to improve practice. Design The design used a qualitative approach and discussion schedule to elicit responses. Setting The setting involved two Aboriginal community controlled and seven mainstream health services in the Far Western region of New South Wales. Participants The participants were experienced diabetes educators ( RNs and AHWs), managers and students currently enrolled in the course (n = 17). Results The results indicated issues that compromise diabetes practice and identified strategies to improve practice. Issues were: the confusing funding practices by health providers, the duplication of health services, the lack of recognition of diabetes qualifications and the transient nature of Indigenous people. Strategies included the need for: continuous dedicated diabetes health funding, a role clarification for diabetes educators, strategic diabetes planning and the importance of diabetes educators working in partnership. Conclusion The conclusion from this study indicates that if the delivery of diabetes health services to Indigenous Australians is to improve it is necessary to address these identified issues.

Background This paper aims to assess the barriers and solutions to the delivery of eye care in primary care settings and solutions to improve the use of comprehensive eye care among Indigenous Australians. Design, setting, participants Qualitative, mixed method study participants include Aboriginal community members, and health and eye care providers in urban, rural and remote settings. Main outcome measures Present evidence for health care providers to better understand and address some of the barriers that limit access to eye care in primary care settings. Results Patient perspectives on barriers to accessing eye care and reasons they choose to seek care or not are presented. Health system barriers identified by health and eye care providers are also presented. Additionally, key enablers for improving access to eye care through primary care services are identified. Conclusion Primary health care services have an important role in Indigenous eye health. There is a critical role for primary care in the coordination of the patient journey and cooperating with other services to improve access to comprehensive eye care. Through improved provision of primary eye care, monitoring of Indigenous eye health indicators and supporting patients to access eye care, it is possible to close the gap for vision.

Objective: To describe the first 9 months of a newly established computed tomography coronary angiogram (CTCA) over the period of the COVID‐19 pandemic. Methods: A retrospective analysis of the first 9 months of a CT‐CA program. Design: Data were collected for the period of June 2020 to March 2021. Information reviewed included demographics, risk factors, renal function, technical factors and outcomes including Calcium Score and Coronary Artery Disease Reporting and Data System (CAD‐RADS). Setting: A single Rural Referral Hospital in regional New South Wales. Participants: Ninety‐six CTCAs were reviewed. Ages ranged from 29 to 81 years. 37 (39%) male, 59 (61%) female. 15 (15.6%) identified as Aboriginal and/or Torres Strait Islander. Main Objective Outcomes: CTCA is a viable alternative to invasive coronary angiogram in appropriate populations for regional areas. Results: Eighty‐eight (91.6%) were considered technically satisfactory. Mean heart rate was 57 beats per minute with a range of 108. Cardiovascular risk factors included hypertension, dyslipidemia, smoking status, family history and diabetes mellitus. Of patients with CAD‐RADS scores 3 or 4 who underwent subsequent invasive coronary angiogram (ICA), 80% were determined to have operator‐defined significant stenosis. Significant cardiac and non‐cardiac findings were extensive. Conclusions: CTCA is a safe and efficacious imaging modality for low‐ to moderate‐risk chest pain patients. There was acceptable diagnostic accuracy and the investigation was safe. [ABSTRACT FROM AUTHOR]

Objective: The objective of this study was to explore data and Aboriginal and non‐Aboriginal researchers' experiences and reflexivity in co‐designing research about a rural Aboriginal well‐being program to inform practice and policy. Setting: Gumbaynggirr, Birpai, Kamilaroi and Awabakal countries located in regional and rural New South Wales, Australia. Participants: Rural and regionally located research team who co‐designed processes to challenge the status quo about a critically framed, rural‐based Aboriginal well‐being research project. Design: Researchers drew on data from a research project in an interpretive cycle of collaborative Yarning. Data included 90 published articles, 12 Yarning transcripts and 26 reflective journal text sets, as well as researcher experiences and reflexivity. Results: The Duguula Gayirray (Yarning together), Yandaarray (walking together) and Duguula Nguraljili (sharing together) co‐design practice model was developed to represent key actions in the context of an Aboriginal well‐being program in a rural context. Actions were supported by seven interpersonal ways of being and were underpinned by respectful relationships between community and researchers. Discussion Duguula Gayirray, Yandaarray and Duguula Nguraljili are critical to co‐design practice and are grounded in respectful relationships. Our experiences led us to critique our perceptions of power sharing, equitable partnerships and collaborative knowledges towards opportunity for collective research co‐design. Conclusion: Duguula Gayirray, Yandaarray and Duguula Nguraljili transformed our understanding of achieving liberation from dominant western research in the context of a rurally located Australian Aboriginal well‐being program. This study contributes to progression of Aboriginal health research practice and policy recommendations, enabling real cultural change in health care with rurally located Aboriginal communities.

Abstract: Aboriginal people in Australia have higher rates of transport injury than non-Aboriginal people, but a greater proportion of Aboriginal people live in rural or remote areas where risk of these injuries is higher. This paper investigated the contributing effect of geography on the relationship between Aboriginality and road transport injury rates in the state of New South Wales. Linked hospital admission and mortality records for individuals for the years 2001–2007 were grouped into distinct injury events. Multilevel Poisson regression was used to examine disparities in injury rates between Aboriginal and non-Aboriginal people clustered within geographic areas of residence. Overall, Aboriginal people had higher rates of road transport injuries (IRR: 1.18, 95% CIs: 1.09–1.28). However, there was no significant difference when geographic clustering was taken into account (IRR: 1.00, 95% CIs: 0.96–1.04). This effect was further influenced by mode of transport for the injury, with Aboriginal people having higher rates of pedestrian (IRR: 1.96, 95% CIs: 1.75–2.19) and lower rates of motorcycle (IRR: 0.64, 95% CIs: 0.59–0.70) injuries in all almost all local areas, while there was no systematic pattern across geographic areas for small vehicle injuries (IRR: 1.01, 95% CIs: 0.94–1.08). Geography plays an important role in the population disparity of road transport injuries between Aboriginal and non-Aboriginal people, and has a differential impact for different types of road transport injury. Exploring how individual and geographic factors influence patterns of disparity allows for clearer targeting of future intervention strategies. [Copyright &y& Elsevier]

Objective: This evaluation considered the potential of We‐Yarn, a suicide prevention gatekeeper training workshop, to contribute to Aboriginal suicide prevention in rural New South Wales. Design: A mixed methods approach included surveys, in‐depth interviews and workshop observations. Setting: Aboriginal suicide prevention training in rural New South Wales, Australia. Participants: Attendees at We‐Yarn training. Intervention: We‐Yarn provided culturally safe suicide prevention skills training for Aboriginal people and for those who work with Aboriginal communities and persons in rural New South Wales. Training workshops were delivered across multiple locations for 6 hours in one day. Workshops were facilitated by two facilitators with lived and professional experience; one Aboriginal and one non‐Aboriginal facilitator. We‐Yarn content was developed by staff from the Centre for Rural and Remote Mental Health, and in consultation with Aboriginal Elders and representatives of Aboriginal Medical Services to ensure relevance and cultural appropriateness. Main outcome measures: Pre and post‐workshop surveys captured capacity and participants' confidence in identifying and responding to a person at risk of suicide. Interviews explored participants' experiences of workshops, implementation of learning, and attitudes regarding social and emotional wellbeing and suicide. Observations detailed the workshop environment, participants' engagement, and participants' responses to facilitators and content. Results: We‐Yarn was considered culturally appropriate. Participants responded to facilitators' lived experiences. Participants reported significant improvements in understanding the links between cultural strengths, social and emotional wellbeing and suicide prevention. However, health professionals with existing knowledge wanted a stronger focus on clinical training. Conclusion: We‐Yarn promoted discussion of suicide prevention within a holistic health framework, building on participants' pre‐existing knowledge about social and emotional wellbeing. Importantly, skilful facilitators with lived experience were vital to the success of the workshops. Consideration should be given to attracting people with low suicide prevention knowledge to the workshops, developing tailored workshops for health professionals and ensuring prolonged engagement with communities. Multifaceted and long term responses in addition to this type of training are important. [ABSTRACT FROM AUTHOR]

Background: Aboriginal and Torres Strait Islander people have high rates of avoidable hospital admissions for chronic conditions, however little is known about the frequency of avoidable admissions for this population. This study examined trends in avoidable admissions among Aboriginal and non-Aboriginal people with chronic conditions in New South Wales (NSW), Australia.Methods: A historical cohort analysis using de-identified linked administrative data of Aboriginal patients and an equal number of randomly sampled non-Aboriginal patients between 2005/06 to 2013/14. Eligible patients were admitted to a NSW public hospital and who had one or more of the following ambulatory care sensitive chronic conditions as a principal diagnosis: diabetic complications, asthma, angina, hypertension, congestive heart failure and/or chronic obstructive pulmonary disease. The primary outcomes were the number of avoidable admissions for an individual in each financial year, and whether an individual had three or more admissions compared with one to two avoidable admissions in each financial year. Poisson and logistic regression models and a test for differences in yearly trends were used to assess the frequency of avoidable admissions over time, adjusting for sociodemographic variables and restricted to those aged ≤75 years.Results: Once eligibility criteria had been applied, there were 27,467 avoidable admissions corresponding to 19,025 patients between 2005/06 to 2013/14 (71.2% Aboriginal; 28.8% non-Aboriginal). Aboriginal patients were 15% more likely than non-Aboriginal patients to have a higher number of avoidable admissions per financial year (IRR = 1.15; 95% CI: 1.11, 1.20). Aboriginal patients were almost twice as likely as non-Aboriginal patients to experience three or more avoidable admissions per financial year (OR = 1.90; 95% CI = 1.60, 2.26). There were no significant differences between Aboriginal and non-Aboriginal people in yearly trends for either the number of avoidable admissions, or whether or not an individual experienced three or more avoidable admissions per financial year (p = 0.859; 0.860 respectively).Conclusion: Aboriginal people were significantly more likely to experience frequent avoidable admissions over a nine-year period compared to non-Aboriginal people. These high rates reflect the need for further research into which interventions are able to successfully reduce avoidable admissions among Aboriginal people, and the importance of culturally appropriate community health care.

Objectives: To describe the current contraception usage patterns from a cohort of Australian Indigenous women, including their ideal family size and spacing between children. Design: Cross‐sectional analysis of data (2012‐2019). Setting: Data are from a longitudinal study, the Gomeroi gaaynggal (babies from Gomeroi lands) program, based in rural and remote Gomeroi lands in New South Wales. Participants: Women carrying an Indigenous baby who enrolled during pregnancy were eligible for the study. The mother and child are then followed for up to 10 years. Main outcome measures: Contraception usage in the postnatal period was recorded, as well as whether they were sexually active, whether they wanted more children and their preferred spacing between children. Medical, social and demographic information was also collected. These measures were self‐reported via an online tool (Survey Monkey®) at their first visit to the study following the birth of their child. Results: Ninety‐nine women were included in the analysis. Most women reported that they were sexually active at the time they were questioned about their contraceptive usage. The most popular contraception choices were condoms, the oral contraceptive pill and implant rods. Those answering that they did not want more children had a median of three children already. Those who wanted more children had a median of one child. The majority of the women stated that 2‐3 years between babies was ideal. Conclusion: The sampled women had clear beliefs about their ideal family size, in which contraceptive usage played an important part. [ABSTRACT FROM AUTHOR]

Problem Chronic kidney disease ( CKD) is a significant health problem impacting Australia's Aboriginal and Torres Strait Islander population. After age adjustment, the prevalence of kidney disease is 3.7 times higher in Aboriginal people and 7.3 times higher for end-stage kidney disease compared with the wider population. Yet at an Aboriginal Community Controlled Health Service ( ACCHS) with a significant patient population, fewer than expected numbers of Aboriginal patients were identified with CKD. Design The ACCHS engaged a nurse practitioner to lead a systematic approach to the identification and treatment of CKD. Setting: This nurse practitioner-led approach to CKD was developed and implemented at a rural NSW ACCHS, with the support of a partnership formed between the nurse practitioner, the ACCHS, a nephrologist from a referral hospital and a statewide NGO. Key measures for improvement The primary measure for improvement has been to identify and stage patients with CKD and establish management plans as appropriate. Strategies for change This nurse-led project was established to: (i) identify patients with CKD; (ii) provide access for CKD patients to appropriate services; (iii) commence pharmacological and non-pharmacological strategies that enable remission or regression of CKD; and (iv) educate practice GPs and other staff members on CKD clinical guidelines and best practice. Effects of change The CKD project has improved access to essential health care for vulnerable and at-risk populations, with 187 patients to date having been identified with kidney disease and staged for its severity. Lessons learnt The need for strong multi-disciplinary teamwork has been demonstrated with good communication strategies implemented. [ABSTRACT FROM AUTHOR]

Background: Cultural awareness and cultural competence have been the focus of the transcultural nursing literature that has explored the roles and responsibilities of nurses in their care of Aboriginal and Torres Strait Islander Peoples. Cultural immersion programs, upholding cultural safety and cultural humility, offer valuable guidance to the education of nursing students regarding Aboriginal and Torres Strait Islander health and cultures. Objectives: This study seeks to explore nursing students' experiences of a cultural immersion program within Aboriginal Medical Services (AMSs) in New South Wales, Australia. Design: Eight nursing students participated in a mixed methods design exploratory study of their clinical placement within AMSs. Methods: A survey gathered data regarding levels of preparation and confidence, learning barriers, placement stressors and personal reflections. Findings: Nursing students reported positive and transformative experiences of intercultural learning. Conclusions: Cultural immersion programs provide a valuable framework for the design and evaluation of clinical placement programs for nursing students within intercultural learning spaces.

Problem Gaps exist in researchers' understanding of the 'practice' of community governance in relation to research with Aboriginal and Torres Strait Islander peoples. Design We examine Aboriginal community governance of two rural NSW research projects by applying principles-based criteria from two independent sources. Setting One research project possessed a strong Aboriginal community governance structure and evaluated a 2-year healthy lifestyle program for children; the other was a 5-year cohort study examining factors influencing the mental health and well-being of participants. Key Measures for improvement The National Health and Medical Research Council of Australia's 'Values and ethics: guidelines for ethical conduct in Aboriginal and Torres Strait Islander research' and 'Ten principles relevant to health research among Indigenous Australian populations' described by experts in the field. Strategies for Change Adopt community-based participatory research constructs. Develop clear governance structures and procedures at the beginning of the study and allow sufficient time for their establishment. Capacity-building must be a key component of the research. Ensure sufficient resources to enable community engagement, conduct of research governance procedures, capacity-building and results dissemination. Effects of change The implementation of governance structures and procedures ensures research addresses the priorities of the participating Aboriginal and Torres Strait Islander communities, minimises risks and improves outcomes for the communities. Lessons Learnt Principles-based Aboriginal and Torres Strait Islander community governance of research is very achievable. Next steps include developing a comprehensive evidence base for appropriate governance structures and procedures, and consolidating a suite of practical guides for structuring clear governance in health research [ABSTRACT FROM AUTHOR]

Background: The University of New England (UNE), Australia decided to develop innovative placement opportunities for its increasing numbers of nursing students. Extensive community and stakeholder consultation determined that a community centre in rural New South Wales was the welcomed site of the student-led clinic because it fit the goals of the project—to increase access to health care services in an underserved area while providing service learning for students. Methods: Supported by a grant from Health Workforce Australia and in partnership with several community organisations, UNE established a student-led clinic in a disadvantaged community using an engaged scholarship approach which joins academic service learning with community based action research. The clinic was managed and run by the students, who were supervised by university staff and worked in collaboration with residents and local health and community services. Results: Local families, many of whom were Indigenous Australians, received increased access to culturally appropriate health services. In the first year, the clinic increased from a one day per week to a three day per week service and offered over 1000 occasions of care and involved 1500 additional community members in health promotion activities. This has led to improved health outcomes for the community and cost savings to the health service estimated to be $430,000. The students learned from members of the community and community members learned from the students, in a collaborative process. Community members benefited from access to drop in help that was self-determined. Conclusions: The model of developing student-led community health and wellbeing clinics in underserved communities not only fulfils the local, State Government, Federal Government and international health reform agenda but it also represents good value for money. It offers free health services in a disadvantaged community, thereby improving overall health and wellbeing. The student-led clinic is an invaluable and sustainable link between students, health care professionals, community based organisations, the university, and the community. The community benefits from the clinic by learning to self-manage health and wellbeing issues. The benefits for students are that they gain practical experience in an interdisciplinary setting and through exposure to a community with unique and severe needs. [ABSTRACT FROM AUTHOR]

Background To investigate variation in rates of cataract surgery in New South Wales, Australia by area of residence for Aboriginal and non- Aboriginal adults. Design Observational data linkage study of hospital admissions. Participants Two hundred eighty-nine thousand six hundred forty-six New South Wales residents aged 30 years and over admitted to New South Wales hospitals for 444 551 cataract surgery procedures between 2001 and 2008. Methods Analysis of linked routinely collected hospital data using direct standardization and multilevel negative binomial regression models accounting for clustering of individuals within Statistical Local Areas. Main Outcome Measures Age-standardized cataract surgery rates and adjusted rate ratios. Results Aboriginal people had lower rates of cataract procedures than non- Aboriginal people of the same age and sex, living in the same Statistical Local Area (adjusted rate ratio 0.71, 95% confidence interval 0.68-0.75). There was significant variation in cataract surgery rates across Statistical Local Areas for both Aboriginal and non- Aboriginal people, with the disparity greater in major cities and less disadvantaged areas. Rates of surgery were lower for Aboriginal than non- Aboriginal people in most Statistical Local Areas, but in a few, the rates were similar or higher for Aboriginal people. Conclusions Aboriginal people in New South Wales received less cataract surgery than non- Aboriginal people, despite evidence of higher cataract rates. This disparity was greatest in urban and wealthier areas. Higher rates of surgery for Aboriginal people observed in some specific locations are likely to reflect the availability of public ophthalmology services, targeted services for Aboriginal people and higher demand for surgery in these populations.

Background: Heart disease is a leading cause of the gap in burden of disease between Aboriginal and non-Aboriginal Australians. Our study investigated short- and long-term mortality after admission for Aboriginal and non-Aboriginal people admitted with acute myocardial infarction (AMI) to public hospitals in New South Wales, Australia, and examined the impact of the hospital of admission on outcomes. Methods: Admission records were linked to mortality records for 60047 patients aged 25-84 years admitted with a diagnosis of AMI between July 2001 and December 2008. Multilevel logistic regression was used to estimate adjusted odds ratios (AOR) for 30- and 365-day all-cause mortality. Results: Aboriginal patients admitted with an AMI were younger than non-Aboriginal patients, and more likely to be admitted to lower volume, remote hospitals without on-site angiography. Adjusting for age, sex, year and hospital, Aboriginal patients had a similar 30-day mortality risk to non-Aboriginal patients (AOR: 1.07; 95% CI 0.83-1.37) but a higher risk of dying within 365 days (AOR: 1.34; 95% CI 1.10-1.63). The latter difference did not persist after adjustment for comorbid conditions (AOR: 1.12; 95% CI 0.91-1.38). Patients admitted to more remote hospitals, those with lower patient volume and those without on-site angiography had increased risk of short and long-term mortality regardless of Aboriginal status.Conclusions: Improving access to larger hospitals and those with specialist cardiac facilities could improve outcomes following AMI for all patients. However, major efforts to boost primary and secondary prevention of AMI are required to reduce the mortality gap between Aboriginal and non-Aboriginal people. [ABSTRACT FROM AUTHOR]

Background: Providing culturally safe health care can contribute to improved health among Aboriginal people. However, little is known about how to make hospitals culturally safe for Aboriginal people. This study assessed the impact of an emergency department (ED)-based continuous quality improvement program on: the accuracy of recording of Aboriginal status in ED information systems; incomplete ED visits among Aboriginal patients; and the cultural appropriateness of ED systems and environments.Methods: Between 2012 and 2014, the Aboriginal Identification in Hospitals Quality Improvement Program (AIHQIP) was implemented in eight EDs in NSW, Australia. A multiple baseline design and analysis of linked administrative data were used to assess program impact on the proportion of Aboriginal patients correctly identified as Aboriginal in ED information systems and incomplete ED visits in Aboriginal patients. Key informant interviews and document review were used to explore organisational changes.Results: In all EDs combined, the AIHQIP was not associated with a reduction in incomplete ED visits in Aboriginal people, nor did it influence the proportion of ED visits made by Aboriginal people that had an accurate recording of Aboriginal status. However, in two EDs it was associated with an increase in the trend of accurate recording of Aboriginality from baseline to the intervention period (odds ratio (OR) 1.31, p < 0.001 in ED 4 and OR 1.15, p = 0.020 in ED 5). In other words, the accuracy of recording of Aboriginality increased from 61.4 to 70% in ED 4 and from 72.6 to 73.9% in ED 5. If the program were not implemented, only a marginal increase would have occurred in ED 4 (from 61.4 to 64%) and, in ED 5, the accuracy of reporting would have decreased (from 72.6 to 71.1%). Organisational changes were achieved across EDs, including modifications to waiting areas and improved processes for identifying Aboriginal patients and managing incomplete visits.Conclusions: The AIHQIP did not have an overall effect on the accuracy of recording of Aboriginal status or on levels of incomplete ED visits in Aboriginal patients. However, important organisational changes were achieved. Further research investigating the effectiveness of interventions to improve Aboriginal cultural safety is warranted. [ABSTRACT FROM AUTHOR]

Background: Admitted patients with chronic disease are at high risk of an unplanned hospital readmission, however, little research has examined unplanned readmission among Aboriginal people in Australia. This study aimed to examine whether rates of unplanned 28 day hospital readmission, or death, significantly differ between Aboriginal and non-Aboriginal patients in New South Wales, Australia, over a nine-year period.Methods: A retrospective cohort analysis of a sample of de-identified linked hospital administrative data was conducted. Eligible patients were: 1) aged ≥18 years old, 2) admitted to an acute facility in a NSW public hospital between 30th June 2005 and 1st July 2014, and 3) admitted with either cardiovascular disease, chronic respiratory disease, diabetes or renal disease. The primary composite outcome was unplanned readmission or death within 28 days of discharge. Generalized linear models and a test for trend were used to assess rates of unplanned readmission or death over time in Aboriginal and non-Aboriginal patients with chronic disease, accounting for sociodemographic variables.Results: The final study cohort included 122,145 separations corresponding to 48,252 patients (Aboriginal = 57.2%, n = 27,601; non-Aboriginal = 42.8%, n = 20,651). 13.9% (n = 16,999) of all separations experienced an unplanned readmission or death within 28 days of discharge. Death within 28 days of discharge alone accounted for only a small number of separations (1.4%; n = 1767). Over the nine-year period, Aboriginal separations had a significantly higher relative risk of an unplanned readmission or death (Relative risk = 1.34 (1.29, 1.40); p-value < 0.0001) compared with non-Aboriginal separations once adjusted for sociodemographic, disease variables and restricted to < 75 years of age. A test for trend, including an interaction between year and Aboriginal status, showed there was no statistically significant change in proportions over the nine-year period for Aboriginal and non-Aboriginal separations (p-value for trend = 0.176).Conclusion: Aboriginal people with chronic disease had a significantly higher risk of unplanned readmission or death 28 days post discharge from hospital compared with non-Aboriginal people, and there has been no significant change over the nine year period. It is critical that effective interventions to reduce unplanned readmissions for Aboriginal people are identified. [ABSTRACT FROM AUTHOR]
