The Link Between Primary Health Care and Health Outcomes for Aboriginal and Torres Strait Islander Australians

5. Conclusion

This review explores the evidence both domestically and internationally as to whether access to high quality primary health care is essential to enhancing Indigenous health status.

This report has taken a new approach to answering the question of how primary health care can contribute to ‘closing the gap’ in life expectancy between Indigenous and non-Indigenous Australia.

Rather than argue predominantly from case studies (which can draw the criticism of leading to ‘policy by anecdote’), or alternatively from the resource deficit between mainstream and Indigenous Australia, we have attempted to take a more rigorous approach. This has involved a new examination of the foundation evidence about the effectiveness of primary health care on population health.

What, then, are the lessons to draw for policy makers and governments in Australia which have the aim of closing the health gap between Indigenous and non-Indigenous Australians within a generation?

We identify several key policy questions – and how the evidence in this report relates to them.

Do health care services matter?

The arguments of Thomas McKeown in the 1970s and the evidence from the social determinants of health have added greatly to our understanding of how critically important economic, social and political factors are in determining the health of populations. Increased understanding, however, of the causal pathways involved in the complex conditions affecting adult populations, including Indigenous people, and advances in medical care, have combined to weaken the more polemic manifestations of the “social determinants” position.

Nonetheless, this position has led to a persistent popular and political argument that health services are fundamentally irrelevant to ‘closing the health gap’134 and that economic and social approaches should be the focus instead.

The evidence does not support such a position. Top of page
Instead, the international evidence is clear about the positive effect of primary health care on the health of populations, and specifically on the health of Indigenous peoples. While unemployment, lack of education, poor housing, low income and social exclusion are all clearly associated with poorer health, the evidence shows that primary health care can ‘offset’ these effects to some extent, particularly through its
beneficial effects on the health of mothers and children and in the management of established adult disease, principally chronic disease.

The policy approach that makes most sense under such circumstances is not one that focuses either on the social determinants of health or on health services, but one that does both. Such an approach is advocated by numerous population health experts, most recently in Australia in the extensive examination of the burden of disease carried by Aboriginal and Torres Strait Islander people, which states that:
... these requirements [to address the social and economic disadvantages that contribute to the poor health status of Indigenous Australians] should not lead to inaction by health policy makers arguing that the social and economic problems should be tackled first. It is within the reach of appropriately resourced health services to reduce a sizeable proportion of the Indigenous health gap.135
The evidence from this review strongly supports that conclusion.

Why have overseas gains not been reflected in Australia?

The evidence shows that Indigenous populations overseas have made gains in health that are attributable to primary health care. Their gains are, however, beyond that seen by Aboriginal and Torres Strait Islander communities as a whole.

We suggest that this is predominantly the result of under-investment in primary health care for Indigenous communities in Australia, compared to the large disadvantage they suffer. This is distinct from the large disadvantage that Aboriginal and Torres Strait Islander people suffer in many of the key social determinants of health such as education, housing, employment and income.

What gains have been made here in recent years have been the result of at best modest increases in primary health care funding against a backdrop where the social determinants of health have also not improved significantly.Top of page
Given the documented ability of primary health care to offset the effects of disadvantage, it is clear from this evidence that Aboriginal and Torres Strait Islander people are yet to fully benefit from what primary health care can deliver.

What needs to be done?

Given that primary health care services – along with action on education, employment, poverty, housing, etc – are an important part of improving the health of Aboriginal and Torres Strait Islander communities, we identify two key policy aims for the Australian Government.

Guaranteeing universal access to primary health care

The comparison in this report of the development of primary health care for Indigenous people and the reduction of avoidable mortality, between Australia and other developed nations, suggests that Australia has underinvested in primary health care. A national commitment by all Governments together to significantly increased investment in primary health care for Aboriginal and Torres Strait Islander people is supported by the evidence.

At the local level, many Indigenous primary health care services are able to document better health outcomes for the communities they serve. However, it is unfortunately, not the case that all Aboriginal and Torres Strait Islander communities have access to such primary health care services. To the extent that such access is only partial, the ability to close the health gap will be, at best, partial.

Increases in Indigenous primary health care funding over the last decade have overwhelmingly been provided by the Australian Government, through increased grant funding from the Office for Aboriginal and Torres Strait Islander Health (OATSIH) and also improved access to the MBS and PBS for Indigenous communities. These increases have, however, been offset by rising health care costs and an increasing Indigenous population.

Nevertheless, many communities have benefited only partially from the increases in primary health care funding provided by the Australian Government. A joint national commitment by all Governments would result either in increased State and Territory investment in primary health care services (including through community-controlled services in their jurisdictions, through funds-pooling models or funding of services such as mental health or substance misuse services for which those jurisdictions generally have responsibility) or in increased Australian Government investment. There are also significant gaps within the areas served by Australian Government funded services. No Australian government is exempt from this call.

We note also the demand made in some previous programs for formal mechanisms of community-control to be established before primary health care services could be established.136 As we have seen, maximum community participation in the running of primary health care is central to their success. However, some communities do not have the ability or desire to take responsibility for running a health service – at least in the short term – and it is problematic to require communities which are amongst the poorest and most disadvantaged in the country to demonstrate sufficient cohesiveness to set up and run their own incorporated organisation before they receive an adequately resourced primary health care service. Already-established community-controlled services and their representative bodies may play a significant role in overcoming this barrier.Top of page
A fundamental policy aim must therefore be that all Aboriginal and Torres Strait Islander communities, whatever the governance structure they may choose, must be guaranteed access to the core functions of primary health care, under models that maximise the participation of the local community. This is equally true for urban, rural and remote areas, each of which pose their own challenges requiring imaginative and flexible solutions in the form of service provided.

The importance of evidence

Ensuring that all Aboriginal and Torres Strait Islander communities have access to primary health care will clearly cost money. However, achieving the greatest gain for any given investment in primary health care is also dependent on implementation of evidence-based best practice.

Services which have an evidence-base are more likely to achieve outcomes in health for the communities they serve. This evidence – in the shape of treatment protocols and a recognition of certain key interventions as an investment in long-term population health – have been increasingly well documented over the period since the transfer of Aboriginal and Torres Strait Islander health to the Commonwealth Health Department. In particular, maternal and child health and the early detection and management of chronic disease are critically important.

Applying this evidence effectively requires a recognition and respect for the diversity of health, cultural and social conditions at a local level, and in practice, attention to the conditions and capacity, needs and priorities of the local Indigenous community.

We would argue that it is no accident that many ‘best-practice’ models are those which emphasise genuine community engagement. It seems that whatever the benefits are in terms of local empowerment and employment (both important from a point-of-view that recognises the importance of the social determinants of health), community controlled health services provide fertile ground for ‘the evidence’ and the views, practices, priorities and needs of the local Indigenous world views to meet and inform each other.
