Successes and challenges of primary health care in Australia: A scoping review and comparative analysis.

Introduction: Australia has achieved universal health insurance for its population since 1975 - a major step forward for increasing access to primary care (PC). Nevertheless, there are reports of several multi-layered challenges, including inequity, that persist. This analysis aims to undertake a scoping review of the success, explanatory factors, and challenges of Primary Health Care (PHC) in Australia guided by the World Health Organization (WHO)-defined key characteristics of good PC. Methods: We searched PubMed, Embase, Scopus and Web of Science using key terms related to PHC principles, attributes, system functioning and health care delivery modalities. We also used key PC terminologies used to assess key characteristics of good PC developed by WHO and key terms and attributes from Australia's health care landscape. We then integrated our search terms with the PHC Search Filters developed by Brown, L., et al. (2014). We restricted the search from 2013 to 2021. Two authors independently assessed study eligibility and performed a quality check on the extracted data. We presented findings according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Results: We identified 112 articles on primary health care (PHC), represented from all Australian states and territories. Overall, Australian PHC has achieved comprehensiveness, access and coverage, quality of care, patient / person centeredness and service coordination indicators with exemplary evidence-base practice/knowledge translation and clinical decision-making practices at the PC settings. Yet, we identified complex and multilayered barriers including geographic and socio-economic berries and inequality, staff dissatisfaction/turn over, low adoption of person-centred care, inadequate sectoral collaboration, and inadequate infrastructure in rural and remote primary care units. Conclusion: Primary health care in Australia, which has evolved through major reforms, has been adapting to the complex health care needs of the socio-culturally diversified nation, and has achieved many of the PC attributes, including service diversity, accessibility, acceptability, and quality of care. Yet, there are persistent gaps in service delivery to socio-economically disadvantaged populations, including indigenous people, culturally and linguistically diverse (CALD) populations, and rural- and remote-residents. These challenges could be mitigated through system-wide and targeted policy-level intervention to further improve service delivery through effective and functional local health service coordination, sectoral integration, and improving health care providers' cultural competence.
