A Silver Fluoride Intervention to Improve Oral Health Trajectories of Young Indigenous Australians: Protocol for a Cluster Randomized Controlled Trial.

BACKGROUND: Indigenous Australian children and adolescents experience profound levels of preventable dental disease. The application of silver fluoride (AgF) to active dental caries is a noninvasive alternative to traditional dental treatment approaches. There is particular utility among Indigenous children and young people with dental fear, who may not have access to timely or culturally safe dental service provisions. OBJECTIVE: The aims of this study are to: (1) assess levels of active dental caries among Indigenous children and young people in 6 Australian states and territories; (2) determine if an AgF intervention reduces levels of active disease over 12-24 months; (3) measure the impact of improved oral health on social and emotional well-being (SEWB) and oral health-related quality of life; and (4) calculate the cost-effectiveness of implementing such an initiative. METHODS: The study will use a 2-arm, parallel cluster randomized controlled trial design. Approximately 1140 Indigenous children and youth aged between 2 and 18 years will be recruited. Each state or territory will have 2 clusters. The intervention group will receive the AgF intervention at the start of the study, with the delayed intervention group receiving the AgF intervention 12 months after study commencement. The primary outcome will be the arrest of active carious lesions, with arrested caries defined as nonpenetration by a dental probe. Secondary outcomes will include SEWB, oral health-related quality of life, and dental anxiety, with covariates including dental behaviors (brushing and dental visits). Effectiveness measures for the economic evaluation will include the number of children and young people managed in primary oral health care without the need for specialist referral, changes in SEWB, the numbers and types of treatments provided, and caries increments. RESULTS: Participant recruitment will commence in May 2023. The first results are expected to be submitted for publication 1 year after a 24-month follow-up. CONCLUSIONS: Our findings have the potential to change the way in which active dental disease among Indigenous children and young people can be managed through the inclusion of specifically tailored AgF applications to improve dental health and SEWB delivered by Indigenous health care workers. Desired impacts include cost savings on expensive dental treatments; improved SEWB, nutrition, social, and learning outcomes; and improved quality of life for both children and young people and their caregivers and the broader Indigenous community. The AgF application could be easily implemented into the training program of Indigenous health workers and yield critical information in the management armamentarium of health and well-being recommendations for Australia's First Peoples.

'At the grass roots level it's about sitting down and talking': exploring quality improvement through case studies with high-improving Aboriginal and Torres Strait Islander primary healthcare services.

OBJECTIVES: Improving the quality of primary care is an important strategy to improve health outcomes. However, responses to continuous quality improvement (CQI) initiatives are variable, likely due in part to a mismatch between interventions and context. This project aimed to understand the successful implementation of CQI initiatives in Aboriginal and Torres Strait Islander health services in Australia through exploring the strategies used by 'high-improving' Indigenous primary healthcare (PHC) services. DESIGN, SETTINGS AND PARTICIPANTS: This strengths-based participatory observational study used a multiple case study method with six Indigenous PHC services in northern Australia that had improved their performance in CQI audits. Interviews with healthcare providers, service users and managers (n=134), documentary review and non-participant observation were used to explore implementation of CQI and the enablers of quality improvement in these contexts. RESULTS: Services approached the implementation of CQI differently according to their contexts. Common themes previously reported included CQI systems, teamwork, collaboration, a stable workforce and community engagement. Novel themes included embeddedness in the local historical and cultural contexts, two-way learning about CQI and the community 'driving' health improvement. These novel themes were implicit in the descriptions of stakeholders about why the services were improving. Embeddedness in the local historical and cultural context resulted in 'two-way' learning between communities and health system personnel. CONCLUSIONS: Practical interventions to strengthen responses to CQI in Indigenous PHC services require recruitment and support of an appropriate and well prepared workforce, training in leadership and joint decision-making, regional CQI collaboratives and workable mechanisms for genuine community engagement. A 'toolkit' of strategies for service support might address each of these components, although strategies need to be implemented through a two-way learning process and adapted to the historical and cultural community context. Such approaches have the potential to assist health service personnel strengthen the PHC provided to Indigenous communities.
