Why primary health care offers a more comprehensive approach to tackling health inequities than primary care.

As governments attempt to focus more intently on how to deal with alarming measures of health disadvantage and inequities, a reformist gaze seems to have settled on the primary care sector. Simultaneously, in literature about this area, whether intended or not, primary health care and primary care are terms that are increasingly interchanged. This article argues that the slippage in language is counter-productive, first because it disguises the transformative potential of strategies and approaches that can make the fundamental changes necessary to improve health status, and second because the structures and practices of the primary care sector are not necessarily compatible with notions of comprehensive primary health care. There is much to be lost if primary health care and health promotion are disguised as primary care, and not understood for their capacity to make a difference to health inequities although of course in some circumstances, comprehensive primary health care is interdependent with services provided by primary care. In this article, characteristics of primary care and primary health care are juxtaposed to show that if the strengths and limitations of each model are understood, they can be mobilised in collaborative partnerships to deal more effectively with health inequities, than our system has so far been able to do.

Prevention of type 2 diabetes in a primary health care setting interim results from the Greater Green Triangle (GGT) Diabetes Prevention Project

Although clinical trials have shown that lifestyle modifications reduce the risk of type 2 diabetes, translating lessons from trials to primary care remains a challenge. The aim of the study was to evaluate efficacy and feasibility of primary care-based diabetes prevention model with modest resource requirements in rural Australia. Three hundred and eleven subjects with at least a moderate risk of type 2 diabetes participated in a combined dietary and physical activity intervention. Clinical measurements and fasting blood samples were taken at the baseline and after intervention. After 3 months intervention, total (change −3.5%, p < 0.001) and LDL cholesterol (−4.8%, p < 0.001) plasma levels as well as body mass index (−2.5%, p < 0.001), weight (−2.5%, p < 0.001), and waist (−1.6%, p < 0.001) and hip (−2.7%, p < 0.001) circumferences reduced significantly. A borderline reduction was found in triglyceride levels (−4.8%, p = 0.058) while no changes were observed in HDL cholesterol (+0.6%, p = 0.525), glucose (+0.06%, p = 0.386), or systolic (−0.98%, p = 0.095) or diastolic (−1.06%, p = 0.134) blood pressure levels. In conclusion, a lifestyle intervention improved health outcomes – especially obesity and blood lipids – in a population at high risk of developing type 2 diabetes. Our results suggest that the present model is effective and feasible to carry out in primary care settings.

Prevention of type 2 diabetes by lifestyle intervention in an Australian primary health care setting : Greater Green Triangle (GGT) Diabetes Prevention Project

Background
Randomised controlled trials demonstrate a 60% reduction in type 2 diabetes incidence through lifestyle modification programmes. The aim of this study is to determine whether such programmes are feasible in primary health care.

Methods
An intervention study including 237 individuals 40–75 years of age with moderate or high risk of developing type 2 diabetes. A structured group programme with six 90 minute sessions delivered during an eight month period by trained nurses in Australian primary health care in 2004–2006. Main outcome measures taken at baseline, three, and 12 months included weight, height, waist circumference, fasting plasma glucose and lipids, plasma glucose two hours after oral glucose challenge, blood pressure, measures of psychological distress and general health outcomes. To test differences between baseline and follow-up, paired t-tests and Wilcoxon rank sum tests were performed.

Results
At twelve months participants' mean weight reduced by 2.52 kg (95% confidence interval 1.85 to 3.19) and waist circumference by 4.17 cm (3.48 to 4.87). Mean fasting glucose reduced by 0.14 mmol/l (0.07 to 0.20), plasma glucose two hours after oral glucose challenge by 0.58 mmol/l (0.36 to 0.79), total cholesterol by 0.29 mmol/l (0.18 to 0.40), low density lipoprotein cholesterol by 0.25 mmol/l (0.16 to 0.34), triglycerides by 0.15 mmol/l (0.05 to 0.24) and diastolic blood pressure by 2.14 mmHg (0.94 to 3.33). Significant improvements were also found in most psychological measures.

Conclusion
This study provides evidence that a type 2 diabetes prevention programme using lifestyle intervention is feasible in primary health care settings, with reductions in risk factors approaching those observed in clinical trials.

A qualitative study of primary health care access, barriers and satisfaction among people with mental illness

Research has found that a substantial proportion of individuals with mental illness have high morbidity and mortality rates, and high under-diagnosis of major physical illnesses. Furthermore, people with a mental illness tend not to seek out or utilise health care services. The reasons for the negative attitudes and behaviour towards health care services among this population have not been investigated. This paper presents findings from a study that investigated the health care service needs of people with mental illness (n = 20), and views from health care providers (n = 16) regarding access to these services by people with a mental illness. Results indicated that psychiatric patients identified a range of barriers to their health care usage and low levels of health care satisfaction. These views were shared with health care professionals. Reasons for these findings and strategies to address these problems so that there is better access to health care services for people with mental illness are discussed.

The origins of contemporary primary health care

This chapter begins by exploring the concept of primary health care (PHC), linking this to relevant international and national policy documents, and introducing the concept of PHC developed by the World Health Organization. The chapter then focuses on the UK. It explains how PHC is not just found within the NHS, reviews the different sectors involved in PHC, and then discusses the current structure of PHC in the NHS. Key concepts, including the primary health care team, primary care trusts and integrated heath and social care trusts, and the relevant current UK policy documents are introduced.

The chapter then moves on to discuss four important issues in the provision of primary health care in the community: health promotion; tackling health inequalities; health and regeneration; and, tackling domestic violence. The subsection on each of these will explain why the issue is of particular significance and review briefly a number of studies/projects which illustrate what is happening/can be done; this will introduce a range of current research. The chapter concludes with a short review of challenges for the future, emphasising the important role that the nursing profession has to play in meeting these challenges.

A cost-based equity weight for use in the economic evaluation of primary health care interventions: case study of the Australian Indigenous population

Background : Efficiency and equity are both important policy objectives in resource allocation. The discipline of health economics has traditionally focused on maximising efficiency, however addressing inequities in health also requires consideration. Methods to incorporate equity within economic evaluation techniques range from qualitative judgements to quantitative outcomes-based equity weights. Yet, due to definitional uncertainties and other inherent limitations, no method has been universally adopted to date. This paper proposes an alternative cost-based equity weight for use in the economic evaluation of interventions delivered from primary health care services.

Methods : Equity is defined in terms of 'access' to health services, with the vertical equity objective to achieve 'equitable access for unequal need'. Using the Australian Indigenous population as an illustrative case study, the magnitude of the equity weight is constructed using the ratio of the costs of providing specific interventions via Indigenous primary health care services compared with the costs of the same interventions delivered via mainstream services. Applying this weight to the costs of subsequent interventions deflates the costs of provision via Indigenous health services, and thus makes comparisons with mainstream more equitable when applied during economic evaluation.

Results : Based on achieving 'equitable access', existing measures of health inequity are suitable for establishing 'need', however the magnitude of health inequity is not necessarily proportional to the magnitude of resources required to redress it. Rather, equitable access may be better measured using appropriate methods of health service delivery for the target group. 'Equity of access' also suggests a focus on the processes of providing equitable health care rather than on outcomes, and therefore supports application of equity weights to the cost side rather than the outcomes side of the economic equation.

Conclusion : Cost-based weights have the potential to provide a pragmatic method of equity weight construction which is both understandable to policy makers and sensitive to the needs of target groups. It could improve the evidence base for resource allocation decisions, and be generalised to other disadvantaged groups who share similar concepts of equity. Development of this decision-making tool represents a potentially important avenue for further health economics research.

What's needed to increase research capacity in rural primary health care

The aim of this study is to identify ways to build research capacity within primary health. A consultation was undertaken in late 2004 using a combination of a one-page survey and a guided meeting format, in a primary health setting in rural NSW. Most (81.3%) of the 134 individuals consulted were part of an Area Health Service, with 12.7% from non-government settings. Most (80.6%) were clinicians, with a third (31.5%) nurses, 8.3% in medicine, and the remainder from a range of allied health professions. Eleven organisations were represented. The main  outcome measures were identification of support needs, processes to enhance research engagement, and barriers and enablers to clinicians’ research  involvement. The results showed that popular delivery modes for research training and support were courses and “one-to- one” advice. Writing topics were generally more popular than others. Common barriers were time and technology issues. A key enabler was a discipline-specific focus. This is one of few rural Australian  consultations on research needs in primary health conducted with a diverse  range of clinicians at the clinician level. It will direct future research capacity  building efforts towards maximising face-to-face discipline specific options and  minimising technology use.

Rural primary health care workers and research : what is their present capacity?

Aims & rationale/Objectives : The main objectives of this project were to:
- conduct an audit of research skills and experience of primary health care staff in nine south western Victorian not-for-profit agencies
- identify capacity for research in five pre-identified areas
- investigate unpublished research endeavours/innovative projects taking place in the linked community organisations.
Methods : A 9-item survey was developed and will be distributed to all primary health care staff at the nine agencies via the internal email system of each organisation. The survey was developed after consultation with several agency directors, to obtain an organisational perspective on research capacity issues. Staff were also invited to take part in informal focus groups exploring key themes.
Principal findings : This study is in progress, and is expected to be completed at the end of March, 2007. Expected findings are the identification of primary health care staff's capacity for research, and discussion of relevant organisational assistance which would develop their research skills or enable continued participation in research.
Discussion : Phase 2 of the Australian PHC Research, Evaluation and Development Strategy aims to support the development and expansion of the primary health care research workforce. Findings from the current study will support this goal by assisting rural primary health care workers to identify the training and support they need to undertake quality research. The data could also be used to: a) assist the consortium to identify common research interests; b) to inform the consortium regarding the potential for collective research efforts; and c) to support funding submissions from the consortium or from individual agencies.
Implications : These findings will help to inform improved strategic planning in relation to building research capacity. The data could also be used by participating agencies to support applications for research grant funding.
