"It's Everybody's and It's Nobody's Responsibility": Stakeholder Perspectives on Aboriginal and Torres Strait Islander Health Equity at the Nexus of Chronic Kidney Disease and Oral Health

Introduction: The effects of racism, oppression, and colonization in Australia are reflected in the inequitable experience of chronic kidney disease (CKD) among Aboriginal and Torres Strait Islander peoples. Despite having the highest incidence of CKD, Aboriginal and Torres Strait Islander people have the lowest rate of kidney transplant, with poor oral health commonly being an obstacle to receiving a transplant. This research reflects the exploratory phase of a larger project aimed at maximizing oral health outcomes for Aboriginal and Torres Strait Islander people living with CKD in Australia through the provision of culturally secure dental care.

Methods: The present research uses reflexive thematic analysis to analyze qualitative data from yarns, interviews, and focus groups with dental, renal, and Aboriginal and Torres Strait Islander stakeholders to generate a conceptual understanding of equity at the nexus of oral health and kidney health. NVivo software was used for organizing data and an inductive line-by-line coding approach.

Results: Twenty-eight stakeholders participated; 12 of the stakeholders identified as Aboriginal and/or Torres Strait Islander, and most were female. Factors at the nexus of oral health and CKD included the continuous effects of colonization, the centrality of cultural security for improved care, as well as several challenges and opportunities at a system level. Challenges included the luxury of oral health access, limited health care team involvement in oral health pathways, high-intensity engagement with medical systems, and no communication between dental and renal teams. Opportunities identified included the role of integrated care, cross-discipline knowledge sharing, Aboriginal and Torres Strait Islander leadership, clear referral pathways, prevention, and assistance with navigating the oral health system.

Conclusion: We argue that collective responsibility for the oral health of Aboriginal and Torres Strait Islander people living with CKD is required for improved health and eligibility for kidney transplant. Cross-discipline collaboration is required to overcome the rigidness of the current colonial and biomedical model that silos oral health and CKD.

Knowledge transfer statement: The siloed approach to management of oral health for Aboriginal and Torres Strait Islander peoples with chronic kidney disease results in low knowledge sharing and communication across chronic disease management teams and can prevent kidney transplantation. Collective responsibility for oral health within this context is required to ensure that just and equitable access to kidney transplant can be achieved.
