Robust and prototypical immune responses toward COVID-19 vaccine in First Nations peoples are impacted by comorbidities.

High-risk groups, including Indigenous people, are at risk of severe COVID-19. Here we found that Australian First Nations peoples elicit effective immune responses to COVID-19 BNT162b2 vaccination, including neutralizing antibodies, receptor-binding domain (RBD) antibodies, SARS-CoV-2 spike-specific B cells, and CD4+ and CD8+ T cells. In First Nations participants, RBD IgG antibody titers were correlated with body mass index and negatively correlated with age. Reduced RBD antibodies, spike-specific B cells and follicular helper T cells were found in vaccinated participants with chronic conditions (diabetes, renal disease) and were strongly associated with altered glycosylation of IgG and increased interleukin-18 levels in the plasma. These immune perturbations were also found in non-Indigenous people with comorbidities, indicating that they were related to comorbidities rather than ethnicity. However, our study is of a great importance to First Nations peoples who have disproportionate rates of chronic comorbidities and provides evidence of robust immune responses after COVID-19 vaccination in Indigenous people.

'All Aboriginal and Torres Strait Islander children should have access to the ASQ-TRAK': Shared vision of an implementation support model for the ASQ-TRAK developmental screener.

ISSUE ADDRESSED: The ASQ-TRAK, a strengths-based approach to developmental screening, has high acceptability and utility across varied Aboriginal and Torres Strait Islander contexts. While substantive knowledge translation has seen many services utilise ASQ-TRAK, we now need to move beyond distribution and support evidence-based scale-up to ensure access. Through a co-design approach, we aimed to (1) understand community partners' perspectives of barriers and enablers to ASQ-TRAK implementation and (2) develop an ASQ-TRAK implementation support model to inform scale-up. METHODS: The co-design process had four phases: (i) partnership development with five community partners (two Aboriginal Community Controlled Organisations); (ii) workshop planning and recruitment; (iii) co-design workshops; and (iv) analysis, draft model and feedback workshops. RESULTS: Seven co-design meetings and two feedback workshops with 41 stakeholders (17 were Aboriginal and Torres Strait Islander), identified seven key barriers and enablers, and a shared vision - all Aboriginal and Torres Strait Islander children and their families have access to the ASQ-TRAK. Implementation support model components agreed on were: (i) ASQ-TRAK training, (ii) ASQ-TRAK support, (iii) local implementation support, (iv) engagement and communications, (v) continuous quality improvement and (vi) coordination and partnerships. CONCLUSIONS: This implementation support model can inform ongoing processes necessary for sustainable ASQ-TRAK implementation nationally. This will transform the way services provide developmental care to Aboriginal and Torres Strait Islander children, ensuring access to high quality, culturally safe developmental care. SO WHAT?: Well-implemented developmental screening leads to more Aboriginal and Torres Strait Islander children receiving timely early childhood intervention services, improving developmental trajectories and optimising long-term health and wellbeing.

Telehealth in remote Australia: a supplementary tool or an alternative model of care replacing face-to-face consultations?

BACKGROUND: The COVID-19 pandemic increased the use of telehealth consultations by telephone and video around the world. While telehealth can improve access to primary health care, there are significant gaps in our understanding about how, when and to what extent telehealth should be used. This paper explores the perspectives of health care staff on the key elements relating to the effective use of telehealth for patients living in remote Australia. METHODS: Between February 2020 and October 2021, interviews and discussion groups were conducted with 248 clinic staff from 20 different remote communities across northern Australia. Interview coding followed an inductive approach. Thematic analysis was used to group codes into common themes. RESULTS: Reduced need to travel for telehealth consultations was perceived to benefit both health providers and patients. Telehealth functioned best when there was a pre-established relationship between the patient and the health care provider and with patients who had good knowledge of their personal health, spoke English and had access to and familiarity with digital technology. On the other hand, telehealth was thought to be resource intensive, increasing remote clinic staff workload as most patients needed clinic staff to facilitate the telehealth session and complete background administrative work to support the consultation and an interpreter for translation services. Clinic staff universally emphasised that telehealth is a useful supplementary tool, and not a stand-alone service model replacing face-to-face interactions. CONCLUSION: Telehealth has the potential to improve access to healthcare in remote areas if complemented with adequate face-to-face services. Careful workforce planning is required while introducing telehealth into clinics that already face high staff shortages. Digital infrastructure with reliable internet connections with sufficient speed and latency need to be available at affordable prices in remote communities to make full use of telehealth consultations. Training and employment of local Aboriginal staff as digital navigators could ensure a culturally safe clinical environment for telehealth consultations and promote the effective use of telehealth services among community members.

Vision, future, cycle and effect: A community life course approach to prevent prenatal alcohol exposure in central Australia.

ISSUE ADDRESSED: Prevention approaches specific to prenatal alcohol exposure (PAE) and foetal alcohol spectrum disorder (FASD) have been identified as urgently needed in Australia, including in Aboriginal and Torres Strait Islander communities. However, very little work has aimed to describe and evaluate health promotion initiatives, especially those developed in rural and remote areas. METHODS: A series of television commercial scripts (scripts) were developed with health promotion staff at an aboriginal and Torres Strait Islander Community Controlled Health Service and piloted with 35 community members across six yarning sessions. RESULTS: Scripts evoked responses in line with two predominant themes: "Strength" and "Community resonance." This process led to the development of a four-part television and radio campaign focusing on a life course approach to prevent prenatal alcohol exposure (PAE) - "Vision," "Future," "Cycle" and "Effect." CONCLUSIONS: Intergenerational influences on PAE were key elements of scripts positively received by community members. Strengths of this work included a flexible approach to development, local aboriginal men and women coordinating the yarning sessions, and the use of local actors and familiar settings. SO WHAT?: Preventing PAE is extraordinarily complex. Initiatives that are culturally responsive and focus on collective responsibility and community action may be crucial to shifting prominent alcohol norms. Future work is necessary to determine the impact of this campaign.

COVID-19 restrictions should only be lifted when it is safe to do so for Aboriginal communities.

The NSW Government has proposed a blanket lifting of COVID-19 restrictions when the proportion of fully vaccinated people rate reaches 70% of the adult population. If implemented, this would have devastating effects on Aboriginal populations. At the present time, vaccination rates in Aboriginal communities remain low. Once restrictions are lifted, unvaccinated people will be at high risk of infection. The risks of serious illness and death among Aboriginal people from a variety of medical conditions are significantly greater than for the wider population. This is also the case with COVID-19 in First Nations populations around the world. The vulnerability of Aboriginal people is an enduring consequence of colonialism and is exacerbated by the fact that many live in overcrowded and poorly maintained houses in communities with under-resourced health services. A current workforce crisis and the demographic structure of the population have further hindered the effectiveness of vaccination programmes. Aboriginal organisations have called on state and federal governments to delay any substantial easing of restrictions until full vaccination rates among Aboriginal and Torres Strait Islander populations aged 16 years and older reach 90-95%. They have also called for additional support in the form of supply of vaccines, enhancement of workforce capacity and appropriate incentives to address hesitancy. Australia remains burdened by the legacy of centuries of harm and damage to its First Nations people. Urgent steps must be taken to avoid a renewed assault on Aboriginal and Torres Strait Islander health.

Feasibility of Implementing Infant Home Visiting in a Central Australian Aboriginal Community.

The Australian Nurse-Family-Partnership Program, an adaption of the Olds' Nurse-Family-Partnership (NFP), commenced in Alice Springs in 2009 (Central Australia FPP), aiming to improve the health and social outcomes of Aboriginal mothers and infants. This study explores the feasibility of NFP implementation in a remote Australian Aboriginal community. Feasibility was defined by programme uptake by eligible women, retention in the programme, actual vs. scheduled visits and extent of programme content delivery. Programme uptake was established from pregnancy data in the patient Clinical Information System and programme referrals to December 31, 2015. Rates of withdrawal, retention and content delivery were derived from FPP data and compared with published NFP data. Modified Poisson regression was used to identify client characteristics associated with retention beyond the child's first birthday. There were 469 valid referrals (43% of eligible pregnancies) and 299 women with at least one completed home visit by December 31, 2015. Of these, 41% completed the programme to the child's second birthday and 53% beyond the child's first birthday. Dominant reasons for leaving were "moved out of service area" (35%) and "declined further participation" (35%). There was a statistically significant positive association for programme retention with later gestational age at referral (RR = 1.27, p value = 0.03). A high proportion (75%) of scheduled visits was achieved and high delivery of programme content (80%). Central Australia FPP is the first implementation of the NFP model in a remote Aboriginal community. This study found that it can be implemented successfully in this setting. Outcome evaluation is needed to test achievement of hypothesised benefits.

Revisiting the ability of Australian primary healthcare services to respond to health inequity.

Equity of access and reducing health inequities are key objectives of comprehensive primary health care. However, the supports required to target equity are fragile and vulnerable to changes in the fiscal and political environment. Six Australian primary healthcare services, five in South Australia and one in the Northern Territory, were followed over 5 years (2009-2013) of considerable change. Fifty-five interviews were conducted with service managers, staff, regional health executives and health department representatives in 2013 to examine how the changes had affected their practice regarding equity of access and responding to health inequity. At the four state government services, seven of 10 previously identified strategies for equity of access and services' scope to facilitate access to other health services and to act on the social determinants of health inequity were now compromised or reduced in some way as a result of the changing policy environment. There was a mix of positive and negative changes at the non-government organisation. The community-controlled service increased their breadth of strategies used to address health equity. These different trajectories suggest the value of community governance, and highlight the need to monitor equity performance and advocate for the importance of health equity.

Periodontal disease and chronic kidney disease among Aboriginal adults; an RCT.

BACKGROUND: This study will assess measures of vascular health and inflammation in Aboriginal Australian adults with chronic kidney disease (CKD), and determine if intensive periodontal intervention improves cardiovascular health, progression of renal disease and periodontal health over a 24-month follow-up. METHODS: The study will be a randomised controlled trial. All participants will receive the periodontal intervention benefits, with the delayed intervention group receiving periodontal treatment 24 months following baseline. Inclusion criteria include being an Aboriginal Australian, having CKD (a. on dialysis; b. eGFR levels of < 60 mls/min/1.73 m(2) (CKD Stages 3 to 5); c. ACR ≥ 30 mg/mmol irrespective of eGFR (CKD Stages 1 and 2); d. diabetes plus albuminuria (ACR ≥ 3 mg/mmol) irrespective of eGFR), having moderate or severe periodontal disease, having at least 12 teeth, and living in Central Australia for the 2-year study duration. The intervention involves intensive removal of dental plaque biofilms by scaling, root-planing and removal of teeth that cannot be saved. The intervention will occur in three visits; baseline, 3-month and 6-month follow-up. The primary outcome will be changes in carotid intima-media thickness (cIMT). Secondary outcomes will include progression of CKD or death as a consequence of CKD/cardiovascular disease. Progression of CKD will be defined by time to the development of the first of: (1) new development of macroalbuminuria; (2) 30 % loss of baseline eGFR; (3) progression to end stage kidney disease defined by eGFR < 15 mLs/min/1.73 m(2); (4) progression to end stage kidney disease defined by commencement of renal replacement therapy. A sample size of 472 is necessary to detect a difference in cIMT of 0.026 mm (SD 0.09) at the significance criterion of 0.05 and a power of 0.80. Allowing for 20 % attrition, 592 participants are necessary at baseline, rounded to 600 for convenience. DISCUSSION: This will be the first RCT evaluating the effect of periodontal therapy on progression of CKD and cardiovascular disease among Aboriginal patients with CKD. Demonstration of a significant attenuation of CKD progression and cardiovascular disease has the potential to inform clinicians of an important, new and widely available strategy for reducing CKD progression and cardiovascular disease for Australia's most disadvantaged population. TRIAL REGISTRATION: This trial is registered with the Australian New Zealand Clinical Trial Registry ANZCTR12614001183673.

Health promotion in Australian multi-disciplinary primary health care services: case studies from South Australia and the Northern Territory.

This paper reports on the health promotion and disease prevention conducted at Australian multi-disciplinary primary health care (PHC) services and considers the ways in which the organizational environment affects the extent and type of health promotion and disease prevention activity. The study involves five PHC services in Adelaide and one in Alice Springs. Four are managed by a state health department and two by boards of governance. The study is based on an audit of activities and on 68 interviews conducted with staff. All the sites undertake health promotion and recognize its importance but all report that this activity is under constant pressure resulting from the need to provide services to people who have health problems. We also found an increased focus on chronic disease management and prevention which prioritized individuals and behavioural change strategies rather than addressing social determinants affecting whole communities. There was little health promotion work that reflected a salutogenic approach to the creation of health. Most activity falls under three types: parenting and child development, chronic disease prevention and mental health. Only the non-government organizations reported advocacy on broader policy issues. Health reform and consequent reorganizations were seen to reduce the ability of some services to undertake health promotion. The paper concludes that PHC in Australia plays an important role in disease prevention, but that there is considerable scope to increase the amount of community-based health promotion which focuses on a salutogenic view of health and which engages in community partnerships.

Attitudes to Short-Term Staffing and Workforce Priorities of Community Users of Remote Aboriginal Community-Controlled Health Services: A Qualitative Study.

In recent years, there has been an increasing trend of short-term staffing in remote health services, including Aboriginal Community-Controlled Health Services (ACCHSs). This paper explores the perceptions of clinic users' experiences at their local clinic and how short-term staffing impacts the quality of service, acceptability, cultural safety, and continuity of care in ACCHSs in remote communities. Using purposeful and convenience sampling, community users (aged 18+) of the eleven partnering ACCHSs were invited to provide feedback about their experiences through an interview or focus group. Between February 2020 and October 2021, 331 participants from the Northern Territory and Western Australia were recruited to participate in the study. Audio recordings were transcribed verbatim, and written notes and transcriptions were analysed deductively. Overall, community users felt that their ACCHS provided comprehensive healthcare that was responsive to their health needs and was delivered by well-trained staff. In general, community users expressed concern over the high turnover of staff. Recognising the challenges of attracting and retaining staff in remote Australia, community users were accepting of rotation and job-sharing arrangements, whereby staff return periodically to the same community, as this facilitated trusting relationships. Increased support for local employment pathways, the use of interpreters to enhance communication with healthcare services, and services for men delivered by men were priorities for clinic users.

Primary health care utilisation and delivery in remote Australian clinics during the COVID-19 pandemic.

INTRODUCTION: The COVID-19 pandemic period (2020 to 2022) challenged and overstretched the capacity of primary health care services to deliver health care globally. The sector faced a highly uncertain and dynamic period that encompassed anticipation of a new, unknown, lethal and highly transmissible infection, the introduction of various travel restrictions, health workforce shortages, new government funding announcements and various policies to restrict the spread of the COVID-19 virus, then vaccination and treatments. This qualitative study aims to document and explore how the pandemic affected primary health care utilisation and delivery in remote and regional Aboriginal and Torres Strait Islander communities. METHODS: Semi-structured interviews were conducted with staff working in 11 Aboriginal Community-Controlled Health Services (ACCHSs) in outer regional, remote and very remote Australia. Interviews were transcribed, inductively coded and thematically analysed. RESULTS: 248 staff working in outer regional, remote and very remote primary health care clinics were interviewed between February 2020 and June 2021. Participants reported a decline in numbers of primary health care presentations in most communities during the initial COVID-19 lock down period. The reasons for the decline were attributed to community members apprehension to go to the clinics, change in work priorities of primary health care staff (e.g. more emphasis on preventing the virus entering the communities and stopping the spread) and limited outreach programs. Staff forecasted a future spike in acute presentations of various chronic diseases leading to increased medical retrieval requirements from remote communities to hospital. Information dissemination during the pre-vaccine roll-out stage was perceived to be well received by community members, while vaccine roll-out stage information was challenged by misinformation circulated through social media. CONCLUSIONS: The ability of ACCHSs to be able to adapt service delivery in response to the changing COVID-19 strategies and policies are highlighted in this study. The study signifies the need to adequately fund ACCHSs with staff, resources, space and appropriate information to enable them to connect with their communities and continue their work especially in an era where the additional challenges created by pandemics are likely to become more frequent. While the PHC seeking behaviour of community members during the COVID-19 period were aligned to the trends observed across the world, some of the reasons underlying the trends were unique to outer regional, remote and very remote populations. Policy makers will need to give due consideration to the potential effects of newly developed policies on ACCHSs operating in remote and regional contexts that already battle under resourcing issues and high numbers of chronically ill populations.

Codesigning enhanced models of care for Northern Australian Aboriginal and Torres Strait Islander youth with type 2 diabetes: study protocol.

INTRODUCTION: Premature onset of type 2 diabetes and excess mortality are critical issues internationally, particularly in Indigenous populations. There is an urgent need for developmentally appropriate and culturally safe models of care. We describe the methods for the codesign, implementation and evaluation of enhanced models of care with Aboriginal and Torres Strait Islander youth living with type 2 diabetes across Northern Australia. METHODS AND ANALYSIS: Our mixed-methods approach is informed by the principles of codesign. Across eight sites in four regions, the project brings together the lived experience of Aboriginal and Torres Strait Islander young people (aged 10-25) with type 2 diabetes, their families and communities, and health professionals providing diabetes care through a structured yet flexible codesign process. Participants will help identify and collaborate in the development of a range of multifaceted improvements to current models of care. These may include addressing needs identified in our formative work such as the development of screening and management guidelines, referral pathways, peer support networks, diabetes information resources and training for health professionals in youth type 2 diabetes management. The codesign process will adopt a range of methods including qualitative interviews, focus group discussions, art-based methods and healthcare systems assessments. A developmental evaluation approach will be used to create and refine the components and principles of enhanced models of care. We anticipate that this codesign study will produce new theoretical insights and practice frameworks, resources and approaches for age-appropriate, culturally safe models of care. ETHICS AND DISSEMINATION: The study design was developed in collaboration with Aboriginal and Torres Strait Islander and non-Indigenous researchers, health professionals and health service managers and has received ethical approval across all sites. A range of outputs will be produced to disseminate findings to participants, other stakeholders and the scholarly community using creative and traditional formats.

STI in remote communities: improved and enhanced primary health care (STRIVE) study protocol: a cluster randomised controlled trial comparing 'usual practice' STI care to enhanced care in remote primary health care services in Australia.

BACKGROUND: Despite two decades of interventions, rates of sexually transmissible infections (STI) in remote Australian Aboriginal communities remain unacceptably high. Routine notifications data from 2011 indicate rates of chlamydia and gonorrhoea among Aboriginal people in remote settings were 8 and 61 times higher respectively than in the non-Indigenous population. METHODS/DESIGN: STRIVE is a stepped-wedge cluster randomised trial designed to compare a sexual health quality improvement program (SHQIP) to usual STI clinical care delivered in remote primary health care services. The SHQIP is a multifaceted intervention comprising annual assessments of sexual health service delivery, implementation of a sexual health action plan, six-monthly clinical service activity data reports, regular feedback meetings with a regional coordinator, training and financial incentive payments. The trial clusters comprise either a single community or several communities grouped together based on geographic proximity and cultural ties. The primary outcomes are: prevalence of chlamydia, gonorrhoea and trichomonas in Aboriginal residents aged 16-34 years, and performance in clinical management of STIs based on best practice indicators. STRIVE will be conducted over five years comprising one and a half years of trial initiation and community consultation, three years of trial conditions, and a half year of data analysis. The trial was initiated in 68 remote Aboriginal health services in the Northern Territory, Queensland and Western Australia. DISCUSSION: STRIVE is the first cluster randomised trial in STI care in remote Aboriginal health services. The trial will provide evidence to inform future culturally appropriate STI clinical care and control strategies in communities with high STI rates.

Learning from alcohol (policy) reforms in the Northern Territory (LEARNT): protocol for a mixed-methods study examining the impacts of the banned drinker register.

INTRODUCTION: The Banned Drinker Register (BDR) was reintroduced in the Northern Territory (NT) in September 2017. The BDR is a supply reduction measure and involves placing people who consume alcohol at harmful levels on a register prohibiting the purchase, possession and consumption of alcohol. The current study aims to evaluate the impacts of the reintroduction of the BDR, in the context of other major alcohol policy initiatives introduced across the NT such as Police Auxiliary Liquor Inspectors and a minimum unit price for alcohol of US$1.30 per standard drink. METHODS AND ANALYSES: The Learning from Alcohol (policy) Reforms in the Northern Territory project will use a mixed-methods approach and contain four major components: epidemiological analysis of trends over time (outcomes include health, justice and social welfare data); individual-level data linkage including those on the BDR (outcomes include health and justice data); qualitative interviews with key stakeholders in the NT (n≥50); and qualitative interviews among people who are, or were previously, on the BDR, as well as the families and communities connected to those on the BDR (n=150). The impacts of the BDR on epidemiological data will be examined using time series analysis. Linked data will use generalised mixed models to analyse the relationship between outcomes and exposures, utilising appropriate distributions. Qualitative data will be analysed using thematic analysis. ETHICS AND DISSEMINATION: Ethics approvals have been obtained from NT Department of Health and Menzies School of Health Research Human Research Ethics Committee (HREC), Central Australia HREC and Deakin University HREC. In addition to peer-reviewed publications, we will report our findings to key organisational, policy, government and community stakeholders via conferences, briefings and lay summaries.

Reaching those with the greatest need: how Australian primary health care service managers, practitioners and funders understand and respond to health inequity.

Equity of access to services and in health outcomes are key goals of primary health care. This study considers understandings of equity and perceptions of current performance in relation to equity among primary health care service staff, health service executives and funders. Semi-structured interviews were conducted with managers, practitioners and administration staff at five primary health care services in Adelaide and one in Alice Springs, as well as with South Australian funders and regional health service executives (n = 68). Services were responding to health inequity by taking actions to improve equitable access to their service, facilitating equitable access to health care more generally, and advocating and taking action on the social determinants of health inequities. As well as availability, affordability and acceptability, our analysis indicated a fourth dimension of equity of access we named 'engagement'. Our respondents were less able to point to examples of advocacy or action on the social determinants of health inequities than they were to examples of actions to improve equity of access. These findings indicate current strengths and also scope to encourage a broader and more comprehensive role for primary health care in addressing health inequities.

Associations with sight-threatening diabetic macular oedema among Indigenous adults with type 2 diabetes attending an Indigenous primary care clinic in remote Australia: a Centre of Research Excellence in Diabetic Retinopathy and Telehealth Eye and Associated Medical Services Network study.

OBJECTIVE: To identify factors associated with sight-threatening diabetic macular oedema (STDM) in Indigenous Australians attending an Indigenous primary care clinic in remote Australia. METHODS AND ANALYSIS: A cross-sectional study design of retinopathy screening data and routinely-collected clinical data among 236 adult Indigenous participants with type 2 diabetes (35.6% men) set in one Indigenous primary care clinic in remote Australia. The primary outcome variable was STDM assessed from retinal images. RESULTS: Age (median (range)) was 48 (21-86) years, and known diabetes duration (median (range)) was 8.0 (0-24) years. Prevalence of STDM was high (14.8%) and similar in men and women. STDM was associated with longer diabetes duration (11.7 vs 7.9 years, respectively; p<0.001) and markers of renal impairment: abnormal estimated Glomerular Filtration Rate (eGFR) (62.9 vs 38.3%, respectively; p=0.007), severe macroalbuminuria (>300 mg/mmol) (20.6 vs 5.7%, respectively; p=0.014) and chronic kidney disease (25.7 vs 12.2%, respectively; p=0.035). Some clinical factors differed by sex: anaemia was more prevalent in women. A higher proportion of men were smokers, prescribed statins and had increased albuminuria. Men had higher blood pressure, but lower glycated Haemoglobin A1c (HbA1c) levels and body mass index, than women. CONCLUSION: STDM prevalence was high and similar in men and women. Markers of renal impairment and longer diabetes duration were associated with STDM in this Indigenous primary care population. Embedded teleretinal screening, known diabetes duration-based risk stratification and targeted interventions may lower the prevalence of STDM in remote Indigenous primary care services.

The Adaptation of a Youth Diabetes Prevention Program for Aboriginal Children in Central Australia: Community Perspectives.

This study reports on integrating community perspectives to adapt a family-focused, culturally appropriate behavioural intervention program to prevent diabetes among Aboriginal children (6-11 years) in Central Australia. A participatory action research approach was used to engage a range of service providers, cultural advisors, and family groups. Appropriateness, acceptability, content, and delivery of a prevention program within the Central Australian context were discussed through a series of workshops with twenty-five service providers and seven family groups separately. The data obtained were deductively coded for thematic analysis. Main findings included: (i) the strong need for a diabetes prevention program that is community owned, (ii) a flexible and culturally appropriate program delivered by upskilling community members as program facilitators, and (iii) consideration of social and environmental factors when implementing the program. It is recommended that a trial of the adapted prevention program for effectiveness and implementation is led by an Aboriginal community-controlled health service.

Understanding and responding to the cost and health impact of short-term health staffing in remote and rural Aboriginal and Torres Strait Islander community-controlled health services: a mixed methods study protocol.

INTRODUCTION: Access to high-quality primary healthcare is limited for remote residents in Australia. Increasingly, remote health services are reliant on short-term or 'fly-in, fly-out/drive-in, drive-out' health workforce to deliver primary healthcare. A key strategy to achieving health service access equity, particularly evident in remote Australia, has been the development of Aboriginal Community Controlled Health Services (ACCHSs). This study aims to generate new knowledge about (1) the impact of short-term staffing in remote and rural ACCHSs on Aboriginal and Torres Strait Islander communities; (2) the potential mitigating effect of community control; and (3) effective, context-specific evidence-based retention strategies. METHODS AND ANALYSIS: This paper describes a 3-year, mixed methods study involving 12 ACCHSs across three states. The methods are situated within an evidence-based programme logic framework for rural and remote primary healthcare services. Quantitative data will be used to describe staffing stability and turnover, with multiple regression analyses to determine associations between independent variables (population size, geographical remoteness, resident staff turnover and socioeconomic status) and dependent variables related to patient care, service cost, quality and effectiveness. Qualitative assessment will include interviews and focus groups with clinical staff, clinic users, regionally-based retrieval staff and representatives of jurisdictional peak bodies for the ACCHS sector, to understand the impact of short-term staff on quality and continuity of patient care, as well as satisfaction and acceptability of services. ETHICS AND DISSEMINATION: The study has ethics approval from the Human Research Ethics Committee of the Northern Territory Department of Health and Menzies School of Health Research (project number DR03171), Central Australian Human Research Ethics Committee (CA-19-3493), Western Australian Aboriginal Health Ethics Committee (WAAHEC-938) and Far North Queensland Human Research Ethics Committee (HREC/2019/QCH/56393). Results will be disseminated through peer-reviewed journals, the project steering committee and community/stakeholder engagement activities to be determined by each ACCHS.
