Aboriginal and Torres Strait Islander Health Workers (A&TSIHWs) are a professional cadre of Australian health workers typically located in primary care clinics. The role is one of only two that is ‘identified’— that is, it must be occupied by an Aboriginal and/or Torres Strait Islander person — and holds specific responsibilities in relation to advocating for facility-level cultural safety. However, lack of understanding of the distinctive skills, scope and value associated with the A&TSIHW role remains pervasive in the broader health workforce. Positioned to represent the perspective of those working as A&TSIHWs, and drawing on 83 in-depth interviews with A&TSIHWs and others, this qualitative study reports on the core functions and distinctive orientation of the role, and seeks to articulate its distinctive value in the modern Queensland health service. Findings highlight the multifaceted (generalist) nature of the A&TSIHW role, which comprises three core functions: health promotion, clinical service and cultural brokerage. Underpinning these cross-cutting functions, is the role’s unique orientation, defined by client-centredness and realised through Indigenous strengths based ways of knowing, being and doing. The findings highlight how the A&TSIHW role is one of the only mechanisms through which Aboriginal and Torres Strait Islander knowledge can be brought to bear on context-specific adaptations to routine health service practices; and through which the impacts of lack of cultural or self-awareness among some non-Indigenous health professionals can be mitigated. The complexity of such work in a government health system where a dominant biomedical culture defines what is valued and therefore resourced, is under-recognised and undervalued and contributes to pressures and stress that are potentially threatening the role's long-term viability.

Background Toxoplasma gondii is a ubiquitous protozoan parasite that can infect virtually all warm-blooded animals. It is the causative agent of toxoplasmosis, a significant public health issue worldwide. Mathematical models are useful to study the transmission dynamics of T. gondii infection in different settings, and may be used to compare the effectiveness of prevention measures. Methods To obtain an overview of existing mathematical models for transmission of T. gondii , a systematic review was undertaken. The review was conducted according to an a priori protocol and the results were reported according to the PRISMA guidelines. Specific search terms were developed and used in the search of three databases (Scopus, PubMed, and Embase). Results In total, 484 unique records were retrieved from the systematic search. Among them, 15 studies that used mathematical models to study the transmission of T. gondii . These studies were categorized into four groups based on the primary aims: dynamics of transmission ( n = 8), intervention ( n = 5), spatial distribution ( n = 1), and outbreak investigation (n = 1). Conclusions Considering the high disease burden caused by T. gondii , the number of studies using mathematical models to understand the transmission dynamics of this parasite and to evaluate the effectiveness of intervention measures was only 15. This systematic review provides an overview of existing mathematical models and identifies the data gaps for model building. The results from this study can be helpful for further development of mathematical models and improved understanding of the transmission dynamics of T. gondii infection.

Background: In northern Australia, Aboriginal and/or Torres Strait Islander Health Workers (A&TSIHWs) are unique members of nominally integrated teams of primary care professionals. Spurred by research documenting ongoing structural violence experienced by Indigenous health providers and more recent challenges to recruitment and retention of A&TSIHWs, this study aimed to explore whether the governance of the A&TSIHW role supports full and meaningful participation. Methods: The qualitative study was co-designed by a team of Aboriginal, Torres Strait Islander and non-Indigenous collaborators. Data collection comprised document review and interviews with A&TSIHWs (n=51), clinicians (n=19) community members (n=8) and administrators (n=5) in a north Queensland health district. We analysed governance at multiple levels (regulatory, organisational, and socio-cultural) and used critical race theory to deepen exploration of the role of race and racism in shaping it. Results: Governance of the A&TSIHW role occurs within a health system where racism is built into, and amplified by, formal and informal rules at all levels. Racially discriminatory structures such as the previous but long-standing relegation of A&TSIHW into the same career stream as cleaners were mirrored in discriminatory rules and managerial practices such as an absence of career-specific corporate support and limited opportunities to participate in, or represent to, key leadership groups. These interacted with and helped perpetuate workplace norms permissive of disrespect and abuse by non-Indigenous professionals. Ongoing resistance to the structural violence required of, and demonstrated by A&TSIHWs speaks to the gap between rhetoric and reality of governance for A&TSIHWs with race and racism at its core. Conclusion: Strengthening governance to support A&TSIHWs requires critical attention be given to the role of race and racism in regulatory structures, organisational practice, and inter-professional relationships. Addressing all domains will be essential to achieve systemic change that recognises, supports and embeds the unique knowledge, skills and functions of the A&TSIHW role.
