Rheumatic heart disease (RHD) caused by acute rheumatic fever (ARF) is a disease of poverty, poor hygiene and poor living standards. RHD remains one of the major causes of childhood cardiac disease in developing nations. Within developed nations, there has been a dramatic drop in the prevalence of RHD because of the improvement of living standards, access to health care and the widespread availability of penicillin-based drugs. Despite a dramatic reduction of RHD in Australia overall, it continues to be a major contributor to childhood and adult cardiac disease in Indigenous communities throughout northern and central Australia. Currently, Australia has among the highest recorded rates of ARF and RHD in the world. The most accurate epidemiological data in Australia come from the Northern Territory's RHD control programme. In the Northern Territory, 92% of people with RHD are Indigenous, of whom 85% live in remote communities and towns. The incidence of ARF is highest in 5-14-year-olds, ranging from 150 to 380 per 100,000. Prevalence rates of RHD since 2000 have steadily increased to almost 2% of the Indigenous population in the Northern Territory, 3.2% in those aged 35-44 years. Living in remote communities is a contributing factor to ARF/RHD as well as a major barrier for adequate follow-up and care. Impediments to ARF/RHD control include the paucity of specialist services, rapid turnover of health staff, lack of knowledge of ARF/RHD by health staff, patients and communities, and the high mobility of the Indigenous population. Fortunately, the recently announced National Rheumatic Fever Strategy, comprising recurrent funding to the Northern Territory, Queensland and Western Australia for control programmes, as well as the creation of a National Coordination Unit suggest that RHD control in Australia is now a tangible prospect. For the disease to be eradicated, Australia will have to address the underpinning determinants of poverty, social and living conditions.
BackgroundRheumatic 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.MethodsWe 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.ResultsSix 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 < 0.001). Large differences in performance were noted between health centres, reflected to some extent in SAT scores.ConclusionsA CQI process using a systems approach and participatory action research methodology can significantly improve delivery of ARF/RHD care.
Scabies is a neglected tropical disease (NTD) that causes a significant health burden, particularly in disadvantaged communities and where there is overcrowding. There is emerging evidence that ivermectin-based mass drug administration (MDA) can reduce the prevalence of scabies in some settings, but evidence remains limited, and there are no formal guidelines to inform control efforts. An informal World Health Organization (WHO) consultation was organized to find agreement on strategies for global control. The consultation resulted in a framework for scabies control and recommendations for mapping of disease burden, delivery of interventions, and establishing monitoring and evaluation. Key operational research priorities were identified. This framework will allow countries to set control targets for scabies as part of national NTD strategic plans and develop control strategies using MDA for high-prevalence regions and outbreak situations. As further evidence and experience are collected and strategies are refined over time, formal guidelines can be developed. The control of scabies and the reduction of the health burden of scabies and associated conditions will be vital to achieving the targets set in WHO Roadmap for NTDs for 2021 to 2030 and the Sustainable Development Goals.
