For tens of thousands of years, Aboriginal and Torres Strait Islander people have operated and thrived within sovereign societies. The sustained and systematic effects of colonisation — which enabled the combined denial of Aboriginal and Torres Strait Islander people's self‐determination, autonomy, leadership, and capability to mobilise health‐benefiting resources — have created the situation in which we find ourselves today of poor health and systemic differences in health care access and outcomes.1 For kidney health in Aboriginal and Torres Strait Islander people, this situation is illustrated through the persistent inequities in kidney failure incidence rates, health system access, and treatment outcomes.2 Recorded rates of kidney failure requiring dialysis or transplantation among Aboriginal and Torres Strait Islander Australians have risen progressively over the past 40 years, remaining consistently higher than rates for non‐Indigenous Australians (Box 1). This difference is even more marked for Aboriginal and Torres Strait Islander people living in rural and remote areas.2 Aboriginal and Torres Strait Islander people have age‐adjusted incidence rates of kidney replacement therapy (KRT) — dialysis or transplantation — eight to nine times higher than those of non‐Indigenous Australians, with the median age of Aboriginal and Torres Strait Islander people who experience kidney failure being nearly 30 years younger than non‐Indigenous people.3 Furthermore, for Aboriginal and Torres Strait Islander people receiving KRT, incidence rates vary considerably between location and age (Box 2), as well as sex (Box 3), with people in the Northern Territory, Western Australia, South Australia, and Queensland experiencing higher rates.2 Finally, the modality with which KRT is delivered differs, with Aboriginal and Torres Strait Islander people predominantly accessing dialysis through facility‐based haemodialysis, with lower rates of home‐based therapies (peritoneal and home haemodialysis).2 Access to kidney transplantation is substantially lower, reflecting lower waitlisting rates.2 Combined, these disparities mean that Aboriginal and Torres Strait Islander people with kidney failure are likely to spend substantially longer (typically years longer) on facility‐based dialysis, away from Country, community, and supportive networks. This dislocation serves to prolong and compound the disconnection, disempowerment and disruption felt by Aboriginal and Torres Strait Islander people when seeking kidney care in Australia.4 Why transplantation mattersFor people with kidney failure, kidney transplantation is the preferred treatment option where possible. Not only is transplantation associated with lower mortality, and a substantial improvement in quality of life,5 it is also less expensive in the long term, particularly when considering the cost of dialysis for rural or remote patients.6 Transplantation therefore provides direct clinical benefits to patients and financial benefits to health systems. Aboriginal and Torres Strait Islander kidney transplant recipients and family members — like nearly all other transplant recipients — also affirm the many health and wellbeing benefits of transplantation,7,8 and numerous community consultations have shown that Aboriginal and Torres Strait Islander people want a better understanding of, and access to, transplantation.9,10,11,12 Disparity in access to transplantation has been recognised for many years.13,14,15,16,17,18 Although absolute rates of waitlisting and transplantation have increased among Aboriginal and Torres Strait Islander peoples, substantial inequity remains in rates of waitlisting and transplantation compared with non‐Indigenous populations, as well as age at diagnosis, pre‐transplant treatment modality, and transplantation outcomes.2 Furthermore, the reasons behind the inequity remain. Studies have consistently shown that inequity in access to transplantation cannot be explained by patient‐ or disease‐related factors,14,15 and that the principal block is on getting onto the waiting list, rather than receiving a kidney once on the list.15 Receiving a kidney transplant requires patients to not just meet specific medical requirements, but also to navigate a complex process that includes multiple investigations, appointments, and ongoing reviews (Box 4). Each stage of this pathway can become a barrier to both waitlisting and transplantation. The difference in waitlisting highlights an important need to focus on the gaps in processes and the barriers within the health system, or more specifically, within clinical services caring for people with kidney disease. To better understand these systemic gaps, in 2018 the Australian Government funded an Expert Panel, through the Transplantation Society of Australia and New Zealand (TSANZ), to undertake a comprehensive review into the hurdles, service gaps, and practical challenges faced by Aboriginal and Torres Strait Islander people receiving treatment for kidney disease. The report recommended 35 high priority actions and mapped responsible agencies, identifying where the federal government could strategically enable cross‐jurisdictional consumer‐ and health service‐partnered approaches.19 From there, in March 2019, the then‐federal Minister for Health and the Minister for Indigenous Australians accepted the report, announcing a $2.3 million award for TSANZ to oversee a two‐year project to coordinate cross‐jurisdictional activity.20 This award established a national Taskforce whose overarching aim was to improve access to, and outcomes of, kidney transplantation for Aboriginal and Torres Strait Islander people. Establishing the TaskforceThe National Indigenous Kidney Transplantation Taskforce (NIKTT) was created to drive the development and implementation of initiatives that targeted knowledge and service delivery gaps identified by the TSANZ report, facilitating improved access to the kidney transplant waitlist and better post‐transplant outcomes for Aboriginal and Torres Strait Islander patients. As this supplement will go on to describe, the Taskforce set out to accomplish this through key objectives around: designing and implementing enhanced data collection and reporting processes on pre‐ and post‐transplant outcomes;improving the equity and accessibility of transplantation for Aboriginal and Torres Strait Islander patients by trialling a range of multidisciplinary service models and protocols; andreviewing existing initiatives that target cultural bias in health services to facilitate best practice care and support. To best inform Taskforce action on these objectives, the NIKTT also created a national network of Aboriginal and Torres Strait Islander consumers and established Indigenous Reference Groups at transplant units around the country. The development of a national Taskforce was critical to provide a focal point. Although many clinicians, researchers, patients and advocates have worked over the years to improve kidney health outcomes for Aboriginal and Torres Strait Islander people, there has not been a cohesive or coordinated approach to these challenges, nor has there been an opportunity to share and collaborate around service development. Led by an appointed Chair and Deputy Chair, the Taskforce was comprised of 24 other expert members including nephrologists, nurses, policy makers, researchers and, crucially, Aboriginal and Torres Strait Islander people with a lived experience of kidney transplantation and dialysis, as well as Aboriginal and/or Torres Strait Islander health workers. Although originally scheduled to be completed within two years, the onset of the coronavirus disease 2019 (COVID‐19) pandemic predictably altered the timeline of project implementation and the NIKTT was granted an extension until June 2023. A strategic focus of the Taskforce was embedding Aboriginal and Torres Strait Islander people's self‐determination and authority into designing models of care that aimed to improve access to kidney transplantation. The NIKTT set out to intentionally consolidate collaboration, partnership and leadership of Aboriginal and Torres Strait Islander people, as before the onset of the NIKTT, there was extremely limited systematic input of Aboriginal and Torres Strait Islander consumers into the processes of care in renal units and none in kidney transplant units. This supplement outlines the recommendations of the Taskforce through describing the outcomes and findings of each objective. We highlight the need for Aboriginal and Torres Strait Islander patient engagement and leadership, the importance of co‐designing models of care unique to local circumstances, and the challenges we still face as a community and health care system seeking to overcome cultural bias and institutional racism. We end this supplement with an overview of the Taskforce's recommendations for next steps and suggest direct actions that systems and services can take to build on the momentum established. The members of the Taskforce are privileged to be part of this foundational work with health communities and Aboriginal and Torres Strait Islander communities across Australia. As we progress equity from here, we look forward to working in partnership with patients, communities, health professionals, governments, health organisations, and research institutions to continue to improve access to kidney transplantation. We begin this supplement with a call to action for readers to join us in improving transplantation equity for all Aboriginal and Torres Strait Islander people with kidney disease. We, as Aboriginal and Torres Strait Islander people, know what is best for our health and wellbeing. While our people and cultures are strong and resilient, we continue to see harmful policies and practices implemented by government. While this can be difficult to hear, true change exists within discomfort, and progress is made when all parties are open to listening and responding.

Kidney transplantation provides better quality and quantity of life for people with kidney failure.1 However, of the 14% of all prevalent dialysis patients who identify as Aboriginal and Torres Strait Islander within the Australia and New Zealand Dialysis and Transplant (ANZDATA) Registry, only 2% were waitlisted in 2021, compared with 8% of non‐Indigenous patients who were waitlisted.2 Equitably addressing this waitlisting gap was a significant priority of the National Indigenous Kidney Transplant Taskforce (NIKTT).3 Many barriers impede Aboriginal and Torres Strait Islander people who live with dialysis from accessing waitlisting, including slow or delayed assessments and referrals, cultural bias, misinformation, and the difficulties of distance (Box).4,5,6,7,8,9 The Commonwealth Department of Health and Aged Care awarded $1.3million to the NIKTT to enable competitive project sponsorships for health care providers to develop models of care that promoted waitlisting attainment. All funded projects extended previously successful models of care to address context‐specific barriers to waitlisting and transplantation. These sponsorship projects were pilots of local care delivery that aimed to overcome context‐specific barriers to kidney transplantation waitlisting. A more detailed evaluation of each of these projects will be available in the NIKTT's final report.10 Here, we provide a commentary on elements of each project that acted as enablers or challenges, to better understand what could be scaled or used to improve services in the future. We outline the strategies used to overcome barriers, what was learned from the projects, and the implications for further practice change. Outreach assessment clinics A substantial barrier to waitlisting in Western Australia is the travel burden required to attend workup appointments, as transplantation assessments typically occur in Perth. Sponsorship was provided for two projects to initiate outreach assessment clinics — found to be culturally sensitive models of care11,12 that increase equity of service delivery13,14 — into regional WA. Led by clinicians at Royal Perth Hospital and Sir Charles Gairdner Hospital and at Fiona Stanley Hospital, these projects were designed to increase the identification, assessment and waitlisting of suitable patients. Multidisciplinary teams, including transplant surgeons, nephrologists, transplant coordinators and renal nurses, attended eight to 15 days of clinics across three to five outreach visits. Alongside these outreach clinics, projects ran transplant education sessions for patients, communities, and health staff. Outreach assessment clinics led to increased numbers of patients activated and transplanted. Outreach clinics increased the number of patients commencing workup, the number of patients waitlisted (while decreasing the time to listing), and the number successfully transplanted (Supporting Information). Communities found the education sessions empowering, with groups in East and West Kimberley now working to form Indigenous Reference Groups.15 Key enablers of these outreach clinics included: (i) a full‐time transplant coordinator role, based locally or in Perth, who aided patient and clinic management; (ii) working closely with local Aboriginal medical services; (iii) patient, community and staff education sessions; and (iv) creating transplantation champions, both patients and staff, who understood regional barriers to transplantation and could motivate others. Key challenges, outside of coronavirus disease 2019 (COVID‐19) travel restrictions, involved the sustained funding of the outreach visits and transplant coordinator roles, as well as regional workforce vacancies. Patient navigators Institutional racism, and its impact on how cultural differences (including language, communication and protocols) influence service delivery, inhibits access to transplantation care.5,6,9 Funding was granted to groups in the Northern Territory, South Australia and Queensland to assist in the employment of patient navigators (or mentors; PNs) — roles that have been found to improve waitlisting through bridging cultural differences and providing otherwise unavailable support.16,17,18,19,20 PNs in this context are Aboriginal and/or Torres Strait Islander people with a lived experience of kidney failure and transplantation. PNs at Purple House (Panuku) in Alice Springs, Port Augusta Hospital Renal Unit, and Cairns and Hinterland Hospital and Health Service were employed to help patients by advocating for their needs, translating health knowledge, and providing culturally safe support. The projects found that PNs helped to increase the number of patients being assessed for eligibility, commencing workup, and being activated on the waitlist (Supporting Information). Navigators were able to develop a level of trust, understanding, effective two‐way communication, and enhanced informed decision making that was previously unseen in these contexts, because of their unique position as brokers of culturally appropriate knowledge and practice alongside lived clinical experience. PNs enabled better access to the waitlist through: (i) identifying and helping more patients undergo assessment; (ii) increasing awareness of transplantation through their presence in renal units and communities; (iii) providing culturally safe support through knowledge and guidance; and (iv) developing more suitable educational materials with renal teams based on patient feedback. Challenges included integrating PN roles into the health system, sustainable funding, and the potential for navigators to burn out without established support mechanisms. A key takeaway from the projects was the concept of the “invisible work” undertaken by PNs — such as late‐night phone calls or talking to patients and doctors about others’ issues when seeking care for themselves. This work is reflective of the holistic role that the navigators fulfil, but which cannot be easily translated into Western metrics. Further examination of this invisible work is ongoing. Educational resources A significant barrier to waitlisting involves the pervasive poor communication from health systems to patients, leading to missed opportunities and culturally unsafe care.6,8,9,21,22 The projects proposed the development of educational sessions and resources to educate patients and care providers on transplantation in local settings. Projects in the NT (Top End Health Service), WA (Royal Perth Hospital and Sir Charles Gairdner Hospital, Fiona Stanley Hospital), SA (Port Augusta Hospital Renal Unit and Pika Wiya Health Service Aboriginal Corporation), and Queensland (Princess Alexandra Hospital) developed patient and staff education sessions to improve understanding of waitlisting and transplantation. Educational sessions included topics such as workup process, remaining on the waitlist, medications, and post‐transplant care. Educational resources were tailored to local contexts by using place‐specific pictures and terms, translating documents into local languages, and consulting communities about the materials produced. Providing local, culturally relevant education to potential transplant patients led to better understanding of the complicated workup and transplant process, creating the opportunity for more patients to engage with workup while enhancing understanding of local processes. Education for health staff improved cultural awareness and understanding of local barriers (Supporting Information). A crucial element of both printed resources and in‐person educational sessions was that patients and communities participated in the development of shared content. The educational sessions especially benefitted from this structure, as they were able to adapt to changing circumstances (such as COVID‐19). Another important aspect of the educational sessions was that many were held on Country. By hosting sessions on the patients’ traditional lands, the projects promoted cultural safety for communities and also improved the cultural awareness and understanding of the visiting clinicians. Areas for development Recruiting, hiring and retaining Aboriginal and/or Torres Strait Islander staff proved challenging from both a workforce and institutional perspective.23,24,25 Two projects experienced workforce difficulties and did not achieve their outcomes. For one project, limitations on team members’ time and the inability to recruit suitable candidates meant the intended implementation of the project was not realised. For another project, significant staff turnover rendered assessment of activities impossible. In other circumstances, Aboriginal and Torres Strait Islander staff were employed but faced challenges within institutions, whether around their role, receiving renumeration, or encountering racism. It is critical that renal services — and the Australian health system generally — learn from these projects. Further development of Aboriginal and Torres Strait Islander roles and how they work with, and are supported by, health systems is essential.26 Most projects also suffered from workforce time pressures, with some finding assessment and reporting burdensome in addition to normal work. This is a common issue to all project‐based work in the health care system, where administrative support is often lacking.27,28,29 As further models are implemented, developing support teams around the delivery and evaluation of care would be beneficial. NIKTT projects found that local management and local answers to complex difficulties were vital to maintain transplant accessibility and project growth.30 A common element to all projects was delivery of the intervention closer to home, especially in regional areas. It is a priority, therefore, that we continue to develop and resource regional centres that can consistently deliver local innovations.31 Conclusion Achieving equity in kidney transplantation is a complex problem that continues to require distinctive solutions across multiple levels of service delivery. Providing workup assessments on Country, employing Aboriginal and Torres Strait Islander people as PNs, and investing in the transplant workforce are key enablers to improving waitlisting, as is the development of culturally and locally relevant education. The sustained resourcing of such models of care, alongside workforce support and integration, could substantially change disparities in waitlisting Australia‐wide.
