Provision of a polypill improved self-reported use of indicated preventive treatments. The lack of differences in blood pressure and cholesterol may reflect limited study power, although for cholesterol, improved statin use in the polypill group counter-balanced use of more potent statins with usual care.

BackgroundExperimentation with continuous quality improvement (CQI) processes is well underway in Indigenous Australian primary health care. To date, little research into how health organizations take up, support, and embed these complex innovations is available on which services can draw to inform implementation. In this paper, we examine the practices and processes in the policy and organisational contexts, and aim to explore the ways in which they interact to support and/or hinder services' participation in a large scale Indigenous primary health care CQI program.MethodsWe took a theory-driven approach, drawing on literature on the theory and effectiveness of CQI systems and the Greenhalgh diffusion of innovation framework. Data included routinely collected regional and service profile data; uptake of tools and progress through the first CQI cycle, and data collected quarterly from hub coordinators on their perceptions of barriers and enablers. A total of 48 interviews were also conducted with key people involved in the development, dissemination, and implementation of the Audit and Best Practice for Chronic Disease (ABCD) project. We compiled the various data, conducted thematic analyses, and developed an in-depth narrative account of the processes of uptake and diffusion into services.ResultsUptake of CQI was a complex and messy process that happened in fits and starts, was often characterised by conflicts and tensions, and was iterative, reactive, and transformational. Despite initial enthusiasm, the mixed successes during the first cycle were associated with the interaction of features of the environment, the service, the quality improvement process, and the stakeholders, which operated to produce a set of circumstances that either inhibited or enabled the process of change. Organisations had different levels of capacity to mobilize resources that could shift the balance toward supporting implementation. Different forms of leadership and organisational linkages were critical to success. The Greenhalgh framework provided a useful starting point for investigation, but we believe it is more a descriptive than explanatory model. As such, it has limitations in the extent to which it could assist us in understanding the interactions of the practices and processes that we observed at different levels of the system.SummaryTaking up CQI involved engaging multiple stakeholders in new relationships that could support services to construct shared meaning and purpose, operationalise key concepts and tools, and develop and embed new practices into services systems and routines. Promoting quality improvement requires a system approach and organization-wide commitment. At the organization level, a formal high-level mandate, leadership at all levels, and resources to support implementation are needed. At the broader system level, governance arrangements that can fulfil a number of policy objectives related to articulating the linkages between CQI and other aspects of the regulatory, financing, and performance frameworks wi...

BackgroundThe disparities in health and life expectancy of Aboriginal and Torres Strait Islander peoples compared to non-Indigenous Australians are well documented. Chronic diseases are a leading contributor to these disparities. We aimed to determine the feasibility, acceptability and appropriateness of a case management approach to chronic disease care integrated within an urban Aboriginal and Torres Strait Islander primary health care service.MethodsThe Home-based, Outreach case Management of chronic disease Exploratory (HOME) Study provided holistic, patient centred multidisciplinary care for Aboriginal and Torres Strait Islander people with chronic disease. A developmental evaluation approach supported the implementation and ongoing adaptations in the delivery of the model of care, and ensured its alignment with Aboriginal and Torres Strait Islander peoples’ understandings of, and approaches to, health and wellbeing. In-depth, semi-structured interviews were conducted with nine patient participants (one interview also included a participant’s spouse) and 15 health service staff and key themes were identified through an iterative reflective process. Quantitative data were collected directly from patient participants and from their medical records at baseline, 3 and 6 months. Patient participants’ baseline characteristics were described using frequencies and percentages. Attrition and patterns of missing values over time were evaluated using binomial generalized estimating equation (GEE) models and mean differences in key clinical outcomes were determined using normal GEE models.ResultsForty-one patients were recruited and nine withdrew over the 6 month period. There was no evidence of differential attrition. All participants (patients and health service staff) were very positive about the model of care. Patient participants became more involved in their health care, depression rates significantly decreased (p = 0.03), and significant improvements in systolic blood pressure (p < 0.001) and diabetes control (p = 0.05) were achieved.ConclusionsThe exploratory nature of our study preclude any definitive statements about the effectiveness of our model of care. However, staff and patients' high levels of satisfaction and improvements in the health and wellbeing of patients are promising and suggest its feasibility, acceptability and appropriateness. Further research is required to determine its efficacy, effectiveness and cost-effectiveness in improving the quality of life and quality of care for Aboriginal and Torres Strait Islander peoples living with chronic disease.

Objective: To examine the trends in processes of diabetes care and in participant outcomes after an intervention in two remote regions of Australia. Design: Follow‐up study over 3 years. Setting: Seven health centres in the Tiwi Islands and the Katherine West region of the Northern Territory. Participants: 137 Aboriginal people with type 2 diabetes. Intervention: Implementation of a multifaceted trial, including transfer of purchasing and planning responsibility to local health boards, the development and dissemination of clinical guidelines supported by electronic registers, recall and reminder systems and associated staff training, and audit and feedback. Main outcome measures: Trends in the proportion of Aboriginal people receiving services in accordance with clinical guidelines and in the proportion for whom specified levels of blood pressure and glycosylated haemoglobin (HbA1c) were achieved; health staff perceptions of barriers to effective service delivery. Results: An initial improvement in overall service levels from 40% to 49% was not fully sustained over the 3‐year period. The overall proportion of services delivered varied from 22% to 64% between communities and over time. The proportion of participants whose most recent HbA1c level was less than 7% improved from 19% to 32%, but there was little change in blood pressure control. Perceived barriers to service delivery included discontinuities in staffing, lack of work‐practice support and patients’ acceptance of services. Conclusions: Multifaceted interventions can improve quality of care in this environment, but achieving sustainable, high‐quality care in a range of services and local conditions presents particular challenges. Developing and testing strategies for consistent and sustained improvement should be a priority for service providers and researchers.

Objective: Given the high prevalence of chronic disease, it is of concern that access to and sustained engagement with primary healthcare services by Aboriginal and Torres Strait Islander Australians is often far lower than would be expected. This study sought to explore ways in which relationships can support sustained engagement with healthcare services. Methods: Semi‐structured interviews were conducted with 126 Aboriginal and Torres Strait Islander participants with and without chronic disease and 97 Aboriginal and Torres Strait Islander and non‐Indigenous healthcare providers, healthcare service managers or administrative staff. Results: Our findings indicate that when faced with acute health issues, Aboriginal and Torres Strait Islander participants did prioritise care, provided that the service was both physically and emotionally welcoming. Trustworthiness of healthcare providers and strong relationships with patients were the most important factors for encouraging sustained engagement overtime. Conclusions: Responsibility for sustaining relationships does not rest solely with Aboriginal and Torres Strait Islander patients. Rather, healthcare providers need to commit to the process of building and maintaining relationships. Implications: First and foremost healthcare providers should take time to establish and then maintain relationships. Healthcare services can also contribute by ensuring facilities are welcoming for Aboriginal and Torres Strait Islander peoples.

Objective: To assess the effect of employing Aboriginal health workers (AHWs) on delivery of diabetes care in remote community health centres, and to identify barriers related to AHWs’ involvement in diabetes and other chronic illness care. Design, setting and participants: Three‐year follow‐up study of 137 Aboriginal people with type 2 diabetes in seven remote community health centres in the Northern Territory. Main outcome measures: Delivery of guideline‐scheduled diabetes services; intermediate outcomes (glycated haemoglobin [HbA1c] and blood pressure levels); number and sex of AHWs at health centres over time; barriers to AHWs’ involvement in chronic illness care. Results: There was a positive relationship between the number of AHWs per 1000 residents and delivery of guideline‐scheduled diabetes services (but not intermediate health outcomes). Presence of male AHWs was associated with higher adherence to the guidelines. Barriers to AHWs’ involvement in chronic illness care included inadequate training, lack of clear role divisions, lack of stable relationships with non‐Aboriginal staff, and high demands for acute care. Conclusions: Employing AHWs is independently associated with improved diabetes care in remote communities. AHWs have potentially important roles to play in chronic illness care, and service managers need to clearly define and support these roles.

Background: Interventions to improve delivery of preventive medical services have been shown to be effective in North America and the UK. However, there are few studies of the extent to which the impact of such interventions has been sustained, or of the impact of such interventions in disadvantaged populations or remote settings. This paper describes the trends in delivery of preventive medical services following a multifaceted intervention in remote community health centres in the Northern Territory of Australia.

Objectives: To evaluate a 12‐month trial of an evidence‐based non‐residential treatment program for Indigenous clients with alcohol problems, offering three streams of care: pharmacotherapy, psychological and social support. Methods: Process evaluation of program implementation; outcome evaluation of client outcomes. Results: Implementation: despite constraints of time and remoteness, the trial demonstrated the feasibility of implementing such a program. The medical stream generated fewer pharmacotherapy prescriptions than expected. The most active stream was the psychological therapy stream. Outcomes: between March 2008 and April 2009, 129 clients were referred to the program, of whom 49 consented to have de‐identified data used for the evaluation. Of these, 19 clients received one or more streams of care, 15 of whom (78.9%) subsequently stopped or reduced drinking. However, among the remaining 30 consenting clients who had not received an intervention, 70.0% also reported stopping or reducing drinking. The evidence of program effectiveness is therefore equivocal and evaluation over a longer period is required. Conclusion and implications: The trial demonstrated the viability of, and demand for, evidence‐based non‐residential treatment for Indigenous clients with alcohol problems. Reasons behind an apparent reluctance among GPs to prescribe pharmacotherapy for Indigenous clients, and steps to overcome this, need further attention.
