In Australia, the incidence rate of breast cancer is lower in Indigenous* women than non-Indigenous women; however, the mortality rate is higher, with Indigenous women 1.2 times more likely to die from the disease. This paper provides practical and achievable solutions to improve health outcomes for Indigenous women with breast cancer in Australia. This research employed the Context–Mechanism–Outcome (CMO) framework to reveal potential mechanisms and contextual factors that influence breast cancer outcomes for Indigenous women, stratified into multiple levels, namely, micro (interpersonal), meso (systemic) and macro (policy) levels. The CMO framework allowed us to interpret evidence regarding Indigenous women and breast cancer and provides nine practical ways to improve health outcomes and survival rates.

To evaluate if existing Australian public policy related to screening, diagnosis, treatment and follow up care for breast cancer addresses the needs of and outcomes for Indigenous¹ women? This review of policy employed a modified Delphi method via an online panel of experts (n = 13), who were purposively recruited according to experience and expertise. A series of online meetings and online surveys were used for data collection. The aims of the study were to: Identify all existing and current breast cancer policy in Australia; Analyse the extent to which consideration of Indigenous peoples is included in the development, design and implementation of the policy; and Identify policy gaps and make recommendations as to how they could be addressed. The policies were evaluated using ‘A Guide to Evaluation under the Indigenous Evaluation Strategy, 2020’. A list of current breast cancer policies (n = 7) was agreed and analysed. Five draft recommendations to improve breast cancer outcomes for Indigenous women were developed and refined by the panel. Current breast cancer policy in Australia does not address the needs of Indigenous women and requires change to improve outcomes.

Breast cancer continues to be the second most diagnosed cancer overall and the most diagnosed cancer for women in Australia. While mortality rates overall have declined in recent years, Indigenous women continue to be diagnosed at more marginal rates (0.9 times) and are more likely to die (1.2 times). The literature provides a myriad of reasons for this; however, the voices of Indigenous women are largely absent. This study sets out to understand what is happening from the perspectives of Australian Indigenous women with a view to charting culturally safer pathways that improve participation in screening and treatment by Indigenous women. This co-design study was conducted using semi-structured, in-depth interviews and focus group discussions. Recruitment of study participants was via snowball sampling. Participants were subsequently consented into the study through the Aboriginal Health Service and the research team. Interviews were audio recorded and transcribed verbatim, and data coded in NVivo12 using inductive thematic analysis. A total of 21 Indigenous women and 14 health service providers were interviewed predominantly from the same regional/rural area in NSW, with a small proportion from other states in Australia. Six major themes were identified: Access, Awareness, Community and Family, Lack of control, Negative feelings and associations and Role of services. To improve access and participation of Indigenous women and ultimately improve mortality rates, breast cancer services must explicitly address cultural and community needs.

The purpose of this review is to compare research evaluation tools to determine whether the tools typically used for assessing the quality of research adequately address issues of Indigenous health and culture, particularly when the studies are intended to benefit Indigenous peoples in urban, regional, rural, and remote settings. Our previously published systematic review evaluated studies about breast cancer using a modified Indigenous community engagement tool (CET). In this study, we evaluated the same studies using two commonly used tools: the Critical Appraisal Skills Programme (CASP) for qualitative research; and the Effective Public Health Practice Project (EPHPP) for quantitative research. The results were then compared to ascertain whether there was alignment between performances in terms of engagement and the CASP/EPHPP metrics. Of the 15 papers, 3 papers scored weakly on both metrics, and are therefore the least likely to offer reliable findings, while 2 papers scored strongly on both metrics, and are therefore the most likely to offer reliable findings. Beyond this summation, it was clear that the results did not align and, therefore, could not be used interchangeably when applied to research findings intended to benefit Indigenous peoples. There does not appear to be a pattern in the relationship between the reliability of the studies and the study settings. In order to address disparities in health outcomes, we must assess research through a typical research quality and cultural engagement and settings lens, ensuring that there is rigour in all aspects of the studies.

The aim was to systematically assess the evidence on whether cultural safety affects breast cancer outcomes with regards to care for Indigenous women in high income countries. We conducted a systematic review in accordance with PRISMA guidelines of peer-reviewed articles in Medline, EMBASE, CINAHL, Scopus, Web of Science, Proquest Sociology and Informit Rural health database and Indigenous collection databases. Key inclusion criteria were: adult female patients with breast cancer; high income country setting; outcome measure, including screening, diagnosis, treatment and follow up care. A total of 15 were selected. We developed a Community Engagement assessment tool in consultation with aboriginal researchers, based on the National Health and Medical Research Councils’ community engagement guidelines, against which studies were appraised. This novel element allowed us to evaluate the literature from a new and highly relevant perspective. Thematic analysis of all 15 studies was also undertaken. Despite limited literature there are evidence-based strategies that are likely to improve outcomes for Indigenous women with breast cancer in high income countries and indicate that culture makes a positive difference. It is also clear that strong Indigenous community leadership and governance at all stages of the research including design is an imperative for feasibility.
