Mapping pandemic responses in urban Indigenous Australia: Reflections on systems thinking and pandemic preparedness.

OBJECTIVES: We investigate some of the strengths and challenges associated with Covid-19 responses in urban Indigenous communities in Brisbane, Australia. Our research reflects on the interconnected dynamics that impact health outcomes and mitigate or exacerbate the risk of Covid-19 spreading within urban Indigenous communities. METHODS: Three systems thinking workshops were held in 2021 with Indigenous and non-Indigenous stakeholders (N15/workshop) from State and Federal services, along with Aboriginal Community Controlled Health Organisations. All worked in the urban Indigenous health sector. Stakeholders produced a Causal Loop Diagram (CLD) incorporating the critical feedbacks determining the dynamics influencing health outcomes. The aim of the research was to help stakeholders' build awareness of how the structure of the system influences health outcomes. RESULTS: Stakeholders identified 6 key dynamics which have a negative or positive impact on mitigating risks of Covid-19 infection. By mapping these dynamics within a CLD, 7 intervention points were identified. CONCLUSIONS: Systems thinking provides a useful tool in identifying the complexities associated with navigating health challenges, but further research is needed to develop frameworks that work in conjunction with Indigenous Australian methodologies. IMPLICATIONS FOR PUBLIC HEALTH: Indigenous voices and communities must lie central to health responses/policies for Indigenous peoples. When systems thinking is done by or in collaboration with stakeholders it provides a visual language that can help design public health policy. What can be ascertained is that their effectiveness is predicated on systems thinking's integration with Indigenous methodologies that acknowledges Indigenous self-determination and challenges Eurocentric representations of health and Indigeneity.

Evaluating the prevalence of current hepatitis C infection and treatment among Aboriginal and Torres Strait Islander peoples who inject drugs in Australia: The ETHOS engage study.

INTRODUCTION: Evaluating progress towards hepatitis C virus (HCV) elimination among Aboriginal and Torres Strait Islander peoples is critical given the disproportionate burden of infection. We examined factors associated with current HCV infection and self-reported treatment among Aboriginal and Torres Strait Islander (hereafter referred to as Aboriginal peoples) and non-Aboriginal peoples who inject drugs (PWID) in Australia. METHODS: ETHOS Engage is an observational cohort study of PWID attending drug treatment and needle and syringe programs in Australia. Participants underwent point-of-care HCV RNA testing (Xpert HCV RNA Viral Load Fingerstick) and completed a questionnaire including self-reported history of HCV treatment. RESULTS: Between May 2018 and June 2021, 2395 participants were enrolled and 555 (23%) identified as Aboriginal (median age 42 years, 58% were men, 63% injected drugs in last month, 76% ever incarcerated). HCV RNA prevalence was 23% among Aboriginal PWID (24% in 2018-2019 and 21% in 2019-2021; p = 0.44), and 21% among non-Aboriginal PWID (24% in 2018-2019 and 16% in 2019-2021; p < 0.001). Self-reported HCV treatment was 65% among Aboriginal PWID (63% in 2018-2019 and 69% in 2019-2021; p = 0.30), and 70% among non-Aboriginal PWID (67% in 2018-2019 and 75% in 2019-2021; p < 0.001). Among Aboriginal PWID, current HCV infection was associated with recently injecting drugs and receiving opioid agonist treatment, and self-reported HCV treatment was negatively associated with younger age, homelessness and recently injecting drugs. DISCUSSION AND CONCLUSIONS: Equitable access to HCV care and prevention is needed to ensure Australia meets its elimination targets among Aboriginal PWID.
