In Australia's Northern Territory, Indigenous mothers account for 33% of births and have high rates of hyperglycemia in pregnancy. The prevalence of type 2 diabetes (T2D) in pregnancy is up to 10-fold higher in Indigenous than non-Indigenous Australian mothers, and the use of metformin is common. We assessed birth outcomes in relation to metformin use during pregnancy from a clinical register.The study included women with gestational diabetes (GDM), newly diagnosed diabetes in pregnancy (DIP), or pre-existing T2D from 2012 to 2016. Data were analyzed for metformin use in the third trimester. Regression models were adjusted for maternal age, body mass index, parity, and insulin use.Of 1649 pregnancies, 814 (49.4%) were to Indigenous women, of whom 234 (28.7%) had T2D (vs 4.6% non-Indigenous women; P 0.001). Metformin use was high in Indigenous women (84%-90% T2D, 42%-48% GDM/DIP) and increased over time in non-Indigenous women (43%-100% T2D, 14%-35% GDM/DIP). Among Indigenous women with GDM/DIP, there were no significant differences between groups with and without metformin in cesarean section (51% vs 39%; adjusted odds ratio [aOR] 1.25, 95% confidence interval [CI] 0.87-1.81), large for gestational age (24% vs 13%; aOR 1.5, 95% CI 0.9-2.5), or serious neonatal adverse events (9.4% vs 5.9%; aOR 1.32, 95% CI 0.68-2.57). Metformin use was independently associated with earlier gestational age (37.7 vs 38.5 weeks), but the risk did not remain independently higher after exclusion of women managed with medical nutrition therapy alone, and the increase in births37 weeks was not significant on multivariate analysis.We found no clear evidence of any adverse outcomes related to the use of metformin for the treatment of hyperglycemia in pregnancy.摘要: 背景 在澳大利亚北部地区, 原住民母亲的婴儿出生率占33%, 她们妊娠期间出现高血糖的风险很高。原住民母亲在妊娠期间的2型糖尿病(T2D)患病率与非原住民澳大利亚母亲相比较要高10倍, 并且经常使用二甲双胍治疗。我们利用临床登记表数据评估了妊娠期间使用二甲双胍治疗与出生结果之间的关系。 方法 这项研究从2012至2016年纳入了妊娠糖尿病(gestational diabetes, GDM)、妊娠期新诊断糖尿病(newly diagnosed diabetes in pregnancy, DIP)以及既往已经存在T2D的妇女。对妊娠晚期使用二甲双胍的数据进行了分析。根据母亲年龄、体重指数、产次以及胰岛素使用情况校正了回归模型。 结果 在1649名孕妇中有814名(49.4%)为原住民妇女, 其中234名(28.7%)为T2D(非原住民妇女T2D比例为4.6%；P 0.001)。原住民妇女的二甲双胍使用率更高(在T2D中为84%-90%, 在GDM/DIP中为42%-48%), 并且在非原住民妇女中随着时间的推移使用率在上升(在T2D中为43%-100%, 在GDM/DIP中为14%-35%)。在合并GDM/DIP的原住民妇女中, 使用二甲双胍治疗组与不使用二甲双胍治疗组之间的剖宫产率(分别为51%与39%; 校正后的odds ratio [aOR]为1.25, 95%置信区间[CI]为0.87-1.81)、出现大胎龄率(分别为24%与13%；aOR为1.5, 95% CI为0.9-2.5)、新生儿出现严重不良事件率(分别为9.4%与5.9%；aOR为1.32, 95% CI为0.68-2.57)都没有显著性差异。使用二甲双胍治疗与胎龄更小(分别为37.7与38.5周)独立相关, 但是将单独接受药物营养治疗的妇女排除之后, 这种风险没有独立地处于较高的水平, 并且多变量分析显示37周的出生率并没有显著地升高。 结论 我们没有发现任何与妊娠期间高血糖妇女使用二甲双胍治疗出现不良结果相关的明确证据。.

Background Crusted scabies is endemic in some remote Aboriginal communities in the Northern Territory (NT) of Australia and carries a high mortality risk. Improvement in active case detection (ACD) for crusted scabies is hampered by a lack of evidence about best practice. We therefore conducted a systematic review of ACD methods for leprosy, a condition with similar ACD requirements, to consider how findings could be informative to crusted scabies detection. Methods and principle findings We conducted systematic searches in MEDLINE, CINAHL, Scopus and the Cochrane Database for Systematic Reviews for studies published since 1999 that reported at least one comparison rate (detection or prevalence rate) against which the yield of the ACD method could be assessed. The search yielded 15 eligible studies from 511. Study heterogeneity precluded meta-analysis. Contact tracing and community screening of marginalised ethnic groups yielded the highest new case detection rates. Rapid community screening campaigns, and those using less experienced screening personnel, were associated with lower suspect confirmation rates. There is insufficient data to assess whether ACD campaigns improve treatment outcomes or disease control. Conclusion This review demonstrates the importance of ACD campaigns in communities facing the highest barriers to healthcare access and within neighbourhoods of index cases. The potential benefit of ACD for crusted scabies is not quantified, however, lessons from leprosy suggest value in follow-up with previously identified cases and their close contacts to support for scabies control and to reduce the likelihood of reinfection in the crusted scabies case. Skilled screening personnel and appropriate community engagement strategies are needed to maximise screening uptake. More research is needed to assess ACD cost effectiveness, impact on disease control, and to explore ACD methods capable of capturing the homeless and highly mobile who may be missed in household centric models., Author summary Crusted scabies is a severely debilitating skin disease with potentially fatal consequences that is endemic in some remote Aboriginal communities in the Northern Territory (NT) of Australia. Early detection is essential to maximise the chance of recovery and help prevent transmission of scabies to others. There is little knowledge about how to actively detect crusted scabies, so we sought relevant knowledge about a disease with many similarities: leprosy. The review demonstrates the importance of ACD campaigns in communities facing the highest barriers to healthcare access and within neighbourhoods of index cases. Lessons for crusted scabies in the NT include the importance of skilled screening personnel and appropriate community engagement strategies to maximise screening uptake. More research is needed to assess ACD cost effectiveness, impact on disease control, and to explore ACD methods capable of capturing the homeless and highly mobile who may be missed in household centric models.

Background Continuous Quality Improvement (CQI) programs have been taken up widely by Indigenous primary health care (PHC) services in Australia and there has been national policy commitment to support this. However, international evidence shows that implementing CQI is challenging, impacts are variable and little is known about the factors that impede or enhance effectiveness. A scoping review was undertaken to explore uptake and implementation in Indigenous PHC, including barriers and enablers to embedding CQI in routine practice. We provide guidance on how research and evaluation might be intensified to support implementation. Methods Searches were conducted in MEDLINE, CINAHL and the Cochrane Database of Systematic Reviews. Key websites and publications were handsearched. Studies conducted in Indigenous PHC which demonstrated some combination of CQI characteristics and assessed some aspect of implementation were included. A two stage analysis was undertaken. Stage 1 identified the breadth and focus of literature. Stage 2 investigated barriers and enablers. The Framework for Performance Assessment in PHC (2008) was used to frame the analysis. Data were extracted on the study type, approach, timeframes, CQI strategies, barriers and enablers. Results Sixty articles were included in Stage 1 and 21 in Stage 2. Barriers to implementing CQI processes relate primarily to professional and organisational processes and operate at multiple levels (individual, team, service, health system) whereas barriers to improved care relate more directly to knowledge of best practice and team processes that facilitate appropriate care. Few studies described implementation timeframes, number of CQI cycles or improvement strategies implemented and only two applied a change theory. Conclusion Investigating barriers and enablers that modify implementation and impacts of CQI poses conceptual and methodological challenges. More complete description of CQI processes, implementation strategies, and barriers and enablers could enhance capacity for comparisons across settings and contribute to better understanding of key success factors.

Background Scabies is a common dermatological condition, affecting more than 130 million people at any time. To evaluate and/or predict the effectiveness and cost-effectiveness of scabies interventions, disease transmission modelling can be used. Objective To review published scabies models and data to inform the design of a comprehensive scabies transmission modelling framework to evaluate the cost-effectiveness of scabies interventions. Methods Systematic literature search in PubMed, Medline, Embase, CINAHL, and the Cochrane Library identified scabies studies published since the year 2000. Selected papers included modelling studies and studies on the life cycle of scabies mites, patient quality of life and resource use. Reference lists of reviews were used to identify any papers missed through the search strategy. Strengths and limitations of identified scabies models were evaluated and used to design a modelling framework. Potential model inputs were identified and discussed. Findings Four scabies models were published: a Markov decision tree, two compartmental models, and an agent-based, network-dependent Monte Carlo model. None of the models specifically addressed crusted scabies, which is associated with high morbidity, mortality, and increased transmission. There is a lack of reliable, comprehensive information about scabies biology and the impact this disease has on patients and society. Discussion Clinicians and health economists working in the field of scabies are encouraged to use the current review to inform disease transmission modelling and economic evaluations on interventions against scabies., Author summary Scabies is a neglected tropical disease affecting more than 130 million people, with major costs on health care systems worldwide. While effective treatments exist, it is unknown which treatment strategies result in the best outcomes against the lowest costs, and to what extent this differs between communities. Health economic modelling can help answer these questions, but has rarely been used in this disease area. This review discusses all available scabies transmission models (n = 4), and uses them to create a new, comprehensive modelling framework. This framework can be used as aid for creating a scabies transmission model, the details of which will be determined by the context (population) and the question being addressed. The current paper also reviews the data that is needed to inform scabies modelling: on scabies biology, quality of life and resource use. Unfortunately, available data is limited and particularly data on crusted scabies (associated with high morbidity and mortality rates) is rare. With this review, we hope to assist researchers and policy makers to predict and/or evaluate the cost-effectiveness of interventions against scabies in their population(s) of interest. To tackle scabies, it is key to use effective treatment strategies in a cost-effective and sustainable way. The models and data described in this review, may help researchers, clinicians and funding bodies to facilitate this.

This paper reviews what is known about the challenges of implementing quality improvement programs and draws on data from a systematic continuous quality improvement (CQI) project in remote communities in Australia and Fiji, known as Audit and Best practice for Chronic Disease, to synthesise lessons and discuss the potential for broader application in low and middle income countries, including Pacific Island countries and territories. Although a number of systematic reviews have indicated that quality improvement programs can be effective in changing professional practice and improving the quality of care and patient outcomes, little is known about the key ingredients for change or how services use and implement different strategies to achieve improvements. We identify key features of an innovative CQI model and factors related to implementation that support improvement in diabetes service delivery and intermediate outcomes. Requirements for supporting CQI are identified and the potential for wider application discussed. It is argued that the participatory action research approach supports innovation and broad-based change and the evidence it has produced extends the current knowledge base and facilitates the translation of knowledge into action, for both policy and practice.

Background: Examining variation in diabetes care across regions/organizations provides insight into underlying factors related to quality of care. The aims of this study were to assess quality of diabetes care and its variation among Aboriginal community health centres in Australia, and to estimate partitioning of variation attributable to health centre and individual patient characteristics. Methods: During 2005–2009, clinical medical audits were conducted in 62 Aboriginal community health centres from four states/territories. Main outcome measures include adherence to guidelines‐scheduled processes of diabetes care, treatment and medication adjustment, and control of HbA1c, blood pressure, total cholesterol and albumin/creatinine ratio (ACR). Results: Wide variation was observed across different categories of diabetes care measures and across centres: (1) overall adherence to delivery of services averaged 57% (range 22–83% across centres); (2) medication adjustment rates after elevated HbA1c: 26% (0–72%); and (3) proportions of patients with HbA < 7% : 27% (0–55%); with blood pressure < 130/80 mmHg: 36%(0–59%). Health centre level characteristics accounted for 36% of the total variation in adherence to process measures, and 3–11% of the total variation in patient intermediate outcomes; the remaining, substantial amount of variation in each measure was attributable to patient level characteristics. Conclusions: Deficiencies in a range of quality of care measures provide multiple opportunities for improvement. The majority of variation in quality of diabetes care appears to be attributable to patient level characteristics. Further understanding of factors affecting variation in the care of individuals should assist clinicians, managers and policy makers to develop strategies to improve quality of diabetes care in Aboriginal communities.

Timeliness of immunisation is important in achieving a protective effect at the individual and population levels. Recent international research has highlighted the importance of organisational features of the health system in timely immunisation. This paper reports on an analysis of the availability of records of timely delivery of childhood immunisations in Indigenous primary care services and organisational features of vaccination programs in different jurisdictions in Australia. The findings demonstrate wide variation in recorded timely delivery of immunisations between health centres within and between jurisdictions. Significant deficiencies in the approach to delivery and recording of immunisations appear to be principally related to fragmented systems of delivery, recording and communication between child health and primary care services. Understanding these deficiencies presents opportunities for improving timely immunisation. Refereed/Peer-reviewed

Background Early onset and high prevalence of chronic disease among Indigenous Australians call for action on prevention. However, there is deficiency of information on the extent to which preventive services are delivered in Indigenous communities. This study examined the variation in quality of preventive care for well adults attending Indigenous community health centres in Australia. Methods During 2005-2009, clinical audits were conducted on a random sample (stratified by age and sex) of records of adults with no known chronic disease in 62 Indigenous community health centres in four Australian States/Territories (sample size 1839). Main outcome measures: i) adherence to delivery of guideline-scheduled services within the previous 24 months, including basic measurements, laboratory investigations, oral health checks, and brief intervention on lifestyle modification; and ii) follow-up of abnormal findings. Results Overall delivery of guideline-scheduled preventive services varied widely between health centres (range 5-74%). Documentation of abnormal blood pressure reading ([greater than or equal to]140/90 mmHg), proteinuria and abnormal blood glucose ([greater than or equal to]5.5 mmol/L) was found to range between 0 and > 90% at the health centre level. A similarly wide range was found between health centres for documented follow up check/test or management plan for people documented to have an abnormal clinical finding. Health centre level characteristics explained 13-47% of variation in documented preventive care, and the remaining variation was explained by client level characteristics. Conclusions There is substantial room to improve preventive care for well adults in Indigenous primary care settings. Understanding of health centre and client level factors affecting variation in the care should assist clinicians, managers and policy makers to develop strategies to improve quality of preventive care in Indigenous communities.

Background Australia's Aboriginal and Torres Strait Islander (Indigenous) populations have disproportionately high rates of adverse perinatal outcomes relative to other Australians. Poorer access to good quality maternal health care is a key driver of this disparity. The aim of this study was to describe patterns of delivery of maternity care and service gaps in primary care services in Australian Indigenous communities. Methods We undertook a cross-sectional baseline audit for a quality improvement intervention. Medical records of 535 women from 34 Indigenous community health centres in five regions (Top End of Northern Territory 13, Central Australia 2, Far West New South Wales 6, Western Australia 9, and North Queensland 4) were audited. The main outcome measures included: adherence to recommended protocols and procedures in the antenatal and postnatal periods including: clinical, laboratory and ultrasound investigations; screening for gestational diabetes and Group B Streptococcus; brief intervention/advice on health-related behaviours and risks; and follow up of identified health problems. Results The proportion of women presenting for their first antenatal visit in the first trimester ranged from 34% to 49% between regions; consequently, documentation of care early in pregnancy was poor. Overall, documentation of routine antenatal investigations and brief interventions/advice regarding health behaviours varied, and generally indicated that these services were underutilised. For example, 46% of known smokers received smoking cessation advice/counselling; 52% of all women received antenatal education and 51% had investigation for gestational diabetes. Overall, there was relatively good documentation of follow up of identified problems related to hypertension or diabetes, with over 70% of identified women being referred to a GP/Obstetrician. Conclusion Participating services had both strengths and weaknesses in the delivery of maternal health care. Increasing access to evidence-based screening and health information (most notably around smoking cessation) were consistently identified as opportunities for improvement across services.

Background Experimentation 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. Methods We 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. Results Uptake 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. Summary Taking 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 within the health system would help define a role and vision for quality improvement.

TO THE EDITOR: Improving access to appropriate, good-quality care in the antenatal and postnatal period is a key part of closing the acknowledged gap between Indigenous and other Australians in perinatal outcomes. Previous research in a large Aboriginal medical service in Queensland demonstrated sustained improvements in perinatal outcome ssociated with a quality improvement approach. Here we describe patterns of the delivery of maternity care and service gaps on a broad scale, using data from baseline clinical audits in 34 Indigenous primary health centres participating in a national quality improvement intervention. Participating services were located across the Northern Territory (Top End and Central Australia), North Queensland, Far West New South Wales and Western Australia. Details of the audit methods have been described previously. Briefly, a random sample of up to 30 clinical records in each service was assessed to determine the degree of adherence to recommended protocols and procedures in the antenatal and postnatal periods. Records of women with an infant aged 2–14 months and who had been resident in the community for at least 6 months of the infant’s gestation were considered eligible for our study. The study was approved by the human research ethics committees in each region, and their Indigenous subcommittees where required. Clinical records of 535 women were assessed. Eighty-nine per cent of the women were Indigenous. However, compared with services in the NT, WA and North Queensland, services in Far West NSW had a higher proportion of nonIndigenous women presenting for antenatal or postnatal care (34% v 0–6%; P < 0.05). Overall, less than half of all women presented for care in the first trimester of pregnancy (Box, page 598). Documentation of routine antenatal investigations and brief interventions or advice regarding health behaviour varied, but generally these services appeared to be underutilised. There was relatively good documentation of follow-up of identified problems relating to hypertension or diabetes, with over 70% of identified women being referred to a general practitioner or obstetrician. However, follow-up of other identified problems, such as inadequate rubella immunity, was poor. Although 53% of women had a recorded postnatal visit, documentation of advice regarding health risk factors during the postnatal period was poor. For about half of all women there was documentation about breastfeeding advice and contraception. But advice about smoking, nutrition or mood (depression) was recorded for only 19%–21% of all women, and advice about sudden infant death syndrome prevention, injury prevention or infection/ hygiene was recorded for only 4%–5% of all women. The clinical audit data presented here indicate that participating services had both strengths and weaknesses in delivering maternal health care. Nevertheless, improving adherence to recommended screening investigations and brief interventions or advice about health behaviours, particularly smoking cessation, in the antenatal and postnatal period were identified as clear areas for improvement across all services. This information represents baseline data to inform the long-term monitoring of a quality improvement intervention. More broadly, it should be useful for informing local, regional and national efforts to promote and assess the quality of primary maternal health care for Indigenous women, and thus help address the persisting unacceptably high rates of poor Indigenous perinatal outcomes in Australia.

Background Indigenous Australians experience disproportionately high prevalence of, and morbidity and mortality from chronic illness such as diabetes, renal disease and cardiovascular disease. Improving the understanding of how Indigenous primary care systems are organised to deliver chronic illness care will inform efforts to improve the quality of care for Indigenous people. Methods This cross-sectional study was conducted in 12 Indigenous communities in Australia's Northern Territory. Using the Chronic Care Model as a framework, we carried out a mail-out survey to collect information on material, financial and human resources relating to chronic illness care in participating health centres. Follow up face-to-face interviews with health centre staff were conducted to identify successes and difficulties in the systems in relation to providing chronic illness care to community members. Results Participating health centres had distinct areas of strength and weakness in each component of systems: 1) organisational influence – strengthened by inclusion of chronic illness goals in business plans, appointment of designated chronic disease coordinators and introduction of external clinical audits, but weakened by lack of training in disease prevention and health promotion and limited access to Medicare funding; 2) community linkages – facilitated by working together with community organisations (e.g. local stores) and running community-based programs (e.g. "health week"), but detracted by a shortage of staff especially of Aboriginal health workers working in the community; 3) self management – promoted through patient education and goal setting with clients, but impeded by limited focus on family and community-based activities due to understaffing; 4) decision support – facilitated by distribution of clinical guidelines and their integration with daily care, but limited by inadequate access to and support from specialists; 5) delivery system design – strengthened by provision of transport for clients to health centres, separate men's and women's clinic rooms, specific roles of primary care team members in relation to chronic illness care, effective teamwork, and functional pathology and pharmacy systems, but weakened by staff shortage (particularly doctors and Aboriginal health workers) and high staff turnover; and 6) clinical information systems – facilitated by wide adoption of computerised information systems, but weakened by the systems' complexity and lack of IT maintenance and upgrade support. Conclusion Using concrete examples, this study translates the concept of the Chronic Care Model (and associated systems view) into practical application in Australian Indigenous primary care settings. This approach proved to be useful in understanding the quality of primary care systems for prevention and management of chronic illness. Further refinement of the systems should focus on both increasing human and financial resources and improving management practice.

Background A growing body of international literature points to the importance of a system approach to improve the quality of care in primary health care settings. Continuous Quality Improvement (CQI) concepts and techniques provide a theoretically coherent and practical way for primary care organisations to identify, address, and overcome the barriers to improvements. The Audit and Best Practice for Chronic Disease (ABCD) study, a CQI-based quality improvement project conducted in Australia's Northern Territory, has demonstrated significant improvements in primary care service systems, in the quality of clinical service delivery and in patient outcomes related to chronic illness care. The aims of the extension phase of this study are to examine factors that influence uptake and sustainability of this type of CQI activity in a variety of Indigenous primary health care organisations in Australia, and to assess the impact of collaborative CQI approaches on prevention and management of chronic illness and health outcomes in Indigenous communities. Methods/design The study will be conducted in 40–50 Indigenous community health centres from 4 States/Territories (Northern Territory, Western Australia, New South Wales and Queensland) over a five year period. The project will adopt a participatory, quality improvement approach that features annual cycles of: 1) organisational system assessment and audits of clinical records; 2) feedback to and interpretation of results with participating health centre staff; 3) action planning and goal setting by health centre staff to achieve system changes; and 4) implementation of strategies for change. System assessment will be carried out using a System Assessment Tool and in-depth interviews of key informants. Clinical audit tools include two essential tools that focus on diabetes care audit and preventive service audit, and several optional tools focusing on audits of hypertension, heart disease, renal disease, primary mental health care and health promotion. The project will be carried out in a form of collaborative characterised by a sequence of annual learning cycles with action periods for CQI activities between each learning cycle. Key outcome measures include uptake and integration of CQI activities into routine service activity, state of system development, delivery of evidence-based services, intermediate patient outcomes (e.g. blood pressure and glucose control), and health outcomes (complications, hospitalisations and mortality). Conclusion The ABCD Extension project will contribute directly to the evidence base on effectiveness of collaborative CQI approaches on prevention and management of chronic disease in Australia's Indigenous communities, and to inform the operational and policy environments that are required to incorporate CQI activities into routine practice.

Objective: To describe changes in delivery of preventive services among adults in Aboriginal communities that occurred in association with a systems-oriented intervention. Design, setting and participants: A quality improvement intervention with a 2-year follow-up was undertaken at 12 Aboriginal community health centres in the Northern Territory between January 2002 and December 2005. The study involved 360 well adults aged 16–49 years who had no known diagnosis of chronic disease. Intervention: Two annual cycles of assessment, feedback workshops, action planning, and implementation of system changes. Assessment included a structured review of health service systems and an audit of clinical records. Main outcome measures: Adherence to guideline-scheduled preventive services including taking basic measurements, laboratory investigations, lifestyle counselling and pneumococcal vaccination. Results: Of 12 preventive services measured, delivery of four services showed improvement over the study period: counselling on diet increased from 3% to 8% (P = 0.018); counselling on physical activity from 2% to 8% (P = 0.006); counselling on smoking from 2% to 11% (P = 0.003); and counselling on alcohol from 2% to 10% (P = 0.007). There was no improvement in important measures such as monitoring of waist circumference, blood pressure and blood glucose level, and delivery of pneumococcal vaccination. Conclusion: Our systems-oriented intervention was associated with some improvement in counselling activities, but no significant improvement in delivery of other preventive services. The main reason may be that implementation focused more on chronic illness

force. 2 In addition to other experience and resources, the Healthy for Life program has drawn on the tools, processes and principles developed through an action–research project in the Northern Territory — the ABCD project. “ABCD” originally stood for Audit for Best practice in Chronic Disease. It has come to represent a structured collaborative approach to improving health services, with potential application in a variety of primary care contexts. The ABCD research project is a collaborative initiative of the Cooperative Research Centre for Aboriginal Health, initially funded by the Australian Health Ministers’ Advisory Council, which brought together federal, state and territory government health agencies; Indigenous community-controlled health organisations; and research agencies. The project commenced in 12 Indigenous community health centres in the Top End of the Northern Territory in 2003. Its commencement was independent of, but more or less in parallel with, various other initiatives contributing to the development of the Healthy for Life program. Here, we discuss some of the key strengths of the approach we have developed, and the evidence and values base for continuous quality improvement (CQI) in this context.

Background Rheumatic heart disease (RHD) remains a major health concern for Aboriginal Australians. A key component of RHD control is prevention of recurrent acute rheumatic fever (ARF) using long-term secondary prophylaxis with intramuscular benzathine penicillin (BPG). This is the most important and cost-effective step in RHD control. However, there are significant challenges to effective implementation of secondary prophylaxis programs. This project aimed to increase understanding and improve quality of RHD care through development and implementation of a continuous quality improvement (CQI) strategy. Methods We used a CQI strategy to promote implementation of national best-practice ARF/RHD management guidelines at primary health care level in Indigenous communities of the Northern Territory (NT), Australia, 2008–2010. Participatory action research methods were employed to identify system barriers to delivery of high quality care. This entailed facilitated discussion with primary care staff aided by a system assessment tool (SAT). Participants were encouraged to develop and implement strategies to overcome identified barriers, including better record-keeping, triage systems and strategies for patient follow-up. To assess performance, clinical records were audited at baseline, then annually for two years. Key performance indicators included proportion of people receiving adequate secondary prophylaxis (≥80% of scheduled 4-weekly penicillin injections) and quality of documentation. Results Six health centres participated, servicing approximately 154 people with ARF/RHD. Improvements occurred in indicators of service delivery including proportion of people receiving ≥40% of their scheduled BPG (increasing from 81/116 [70%] at baseline to 84/103 [82%] in year three, p = 0.04), proportion of people reviewed by a doctor within the past two years (112/154 [73%] and 134/156 [86%], p = 0.003), and proportion of people who received influenza vaccination (57/154 [37%] to 86/156 [55%], p = 0.001). However, the proportion receiving ≥80% of scheduled BPG did not change. Documentation in medical files improved: ARF episode documentation increased from 31/55 (56%) to 50/62 (81%) (p = 0.004), and RHD risk category documentation from 87/154 (56%) to 103/145 (76%) (p

Background Aboriginal people in Australia experience the highest prevalence of diabetes in the country, an excess of preventable complications and early death. There is increasing evidence demonstrating the importance of healthcare systems for improvement of chronic illness care. The aims of this study were to assess the status of systems for chronic illness care in Aboriginal community health centres, and to explore whether more developed systems were associated with better quality of diabetes care. Methods This cross-sectional study was conducted in 12 Aboriginal community health centres in the Northern Territory of Australia. Assessment of Chronic Illness Care scale was adapted to measure system development in health centres, and administered by interview with health centre staff and managers. Based on a random sample of 295 clinical records from attending clients with diagnosed type 2 diabetes, processes of diabetes care were measured by rating of health service delivery against best-practice guidelines. Intermediate outcomes included the control of HbA1c, blood pressure, and total cholesterol. Results Health centre systems were in the low to mid-range of development and had distinct areas of strength and weakness. Four of the six system components were independently associated with quality of diabetes care: an increase of 1 unit of score for organisational influence, community linkages, and clinical information systems, respectively, was associated with 4.3%, 3.8%, and 4.5% improvement in adherence to process standards; likewise, organisational influence, delivery system design and clinical information systems were related to control of HbA1c, blood pressure, and total cholesterol. Conclusion The state of development of health centre systems is reflected in quality of care outcome measures for patients. The health centre systems assessment tool should be useful in assessing and guiding development of systems for improvement of diabetes care in similar settings in Australia and internationally.

Background: Diabetes in pregnancy carries an increased risk of adverse pregnancy outcomes for both the mother and foetus, but it also provides an excellent early opportunity for intervention in the life course for both mother and baby. In the context of the escalating epidemic of chronic diseases among Indigenous Australians, it is vital that this risk is reduced as early as possible in the life course of the individual. The aims of the PANDORA Study are to: (i) accurately assess rates of diabetes in pregnancy in the Northern Territory (NT) of Australia, where 38% of babies are born to Indigenous mothers; (ii) assess demographic, clinical, biochemical, anthropometric, socioeconomic and early life development factors that may contribute to key maternal and neonatal birth outcomes associated with diabetes in pregnancy; and (iii) monitor relevant post-partum clinical outcomes for both the mothers and their babies. Methods/Design: Eligible participants are all NT women with diabetes in pregnancy aged 16 years and over. Information collected includes: standard antenatal clinical information, diagnosis and management of diabetes in pregnancy, socio-economic status, standard clinical birth information (delivery, gestational age, birth weight, adverse antenatal and birth outcomes). Cord blood is collected at the time of delivery and detailed neonatal anthropometric measurements performed within 72 hours of birth. Information will also be collected regarding maternal postpartum glucose tolerance and cardio-metabolic risk factor status, breastfeeding and growth of the baby up to 2 years post-partum in the first instance. Discussion: This study will accurately document rates and outcomes of diabetes in pregnancy in the NT of Australia, including the high-risk Indigenous Australian population. The results of this study should contribute to policy and clinical guidelines with the goal of reducing the future risk of obesity and diabetes in both mothers and their offspring.
