Background: Australia’s healthcare system is complex and fragmented which can create challenges in healthcare, particularly in rural and remote areas. Aboriginal people experience inequalities in healthcare treatment and outcomes. This study aimed to investigate barriers and enablers to accessing healthcare services for Aboriginal people living in regional and remote Australia. Methods: Semi-structured interviews were conducted with healthcare delivery staff and stakeholders recruited through snowball sampling. Three communities were selected for their high proportion of Aboriginal people and diverse regional and remote locations. Thematic analysis identified barriers and enablers. Results: Thirty-one interviews were conducted in the three communities (n = 5 coastal, n = 13 remote, and n = 13 border) and six themes identified: (1) Improved coordination of healthcare services; (2) Better communication between services and patients; (3) Trust in services and cultural safety; (4) Importance of prioritizing health services by Aboriginal people; (5) Importance of reliable, affordable and sustainable services; (6) Distance and transport availability. These themes were often present as both barriers and enablers to healthcare access for Aboriginal people. They were also present across the healthcare system and within all three communities. Conclusions: This study describes a pathway to better healthcare outcomes for Aboriginal Australians by providing insights into ways to improve access.

A community-led oral health service for Aboriginal people in Central Northern NSW identified the need for oral health promotion, as well as dental treatment; in three remote communities with limited access to dental services. A three-stage plan based on the Precede-Proceed model was used to develop a school-based preventive oral health program. The program will be piloted in three schools over 12 months aimed at improving the oral health of local Aboriginal children. The proposed program includes four components: daily in-school toothbrushing; distribution of free fluoride toothpaste and toothbrushes; in-school and community dental health education and the installation of refrigerated and chilled water fountains to supply a school water bottle program. Primary school children will be issued toothbrushing kits to be kept at school to facilitate daily brushing using a fluoride toothpaste under the supervision of trained teachers and/or Oral Health Aides. School children, parents and guardians will be issued free fluoride toothpaste and toothbrushes for home use at three-monthly intervals. Four dental health education sessions will be delivered to children at each school and parents/guardians at local community health centres over the 12 month pilot. Dental education will be delivered by an Oral Health Therapist and local Aboriginal Dental Assistant. The program will also facilitate the installation of refrigerated and filtered water fountain to ensure cold and filtered water is available at schools. A structured school water bottle program will encourage the consumption of water. A process evaluation will be undertaken to assess the efficiency, feasibility and effectiveness of the pilot program. The proposed program includes four core evidence-based components which can be implemented in rural and remote schools with a high Aboriginal population. Based on the Precede-Proceed model, this program seeks to empower the local Aboriginal community to achieve improved oral health outcomes. TRN: ISRCTN16110292 Date of Registration: 20 June 2018.

This paper presents the findings of the National Fluoride Varnish Workshop in 2018 along with subsequent actions to scale-up the use of fluoride varnish nationally in Australia. The use of fluoride varnish programs to prevent dental caries in high-risk child populations is an evidence-based population health approach used internationally. Such programs have not been implemented at scale nationally in Australia. A National Fluoride Varnish Consensus Workshop was held in Sydney in November 2018 with an aim of sharing the current work in this area being undertaken by various Australian jurisdictions and seeking consensus on key actions to improve the scale-up nationally. Forty-four people attended the Workshop with oral health representatives from all Australian state and territory health departments, as well as the Australian Dental Association (ADA) at both NSW branch and Federal levels. There was strong support for further scale-up of fluoride varnish programs nationally and to see the wider use of having non-dental professionals apply the varnish. This case study identifies key actions required to ensure scale-up of systematic fluoride varnish programs as part of a strategic population oral health approach to preventing dental caries among high-risk children who may not routinely access dental care.

Australian Aboriginal children experience high levels of dental caries (tooth decay) and are less likely to access preventive dental health services. High-strength fluoride varnish has been shown to reduce the incidence of dental caries and is commonly used in community-based preventive dental health service programs. In New South Wales, Australia, the application of fluoride varnish is restricted to dental and medical professionals. This is problematic in communities with a high Aboriginal population and limited access to oral health services, contributing to the increased risk of developing dental caries in Aboriginal children. Dental assistants are essential members of the oral health team; however, they do not have a defined scope of practice in Australia. Other countries have created formal scopes of practice for dental assistants to include the application of fluoride varnish. This protocol presents a pathway for qualified Aboriginal dental assistants to undertake additional training to legally apply fluoride varnish in New South Wales. The primary objective of this study will be to evaluate the feasibility and acceptability of utilising Aboriginal dental assistants to apply fluoride varnish to Aboriginal children in a school setting at regular 3-month intervals. Six schools across New South Wales (NSW) that enrol at least 12% Aboriginal children will be invited to participate in the 12-month study. Aboriginal children aged 5–12 years enrolled in these schools will be enrolled in the study. Six Aboriginal dental assistants will undertake training to apply fluoride varnish. Fluoride varnish (Duraphat) will be applied at 3-month intervals by the dental assistants to the teeth using a small brush. An evaluation will be undertaken to determine the feasibility and cost-effectiveness of this innovative approach. This study protocol has been approved by the NSW Aboriginal Health and Medical Research Council and the NSW State Education Research Application Process. A qualified Aboriginal dental assistant workforce in NSW (or Australia) legally approved to apply fluoride varnish may increase the sustainability and scalability of fluoride varnish programs and improve the oral health of Aboriginal children in Australia.
