Rotavirus and the indigenous children of the Australian outback: monovalent vaccine effective in a high-burden setting

Indigenous children living in arid Central Australia experience frequent outbreaks of rotavirus gastroenteritis. A widespread outbreak of G9 rotavirus infection occurred several months after introduction of the RIX4414 rotavirus vaccine. We performed a retrospective case-control study to determine vaccine efficacy during the outbreak. Two doses provided an estimated vaccine efficacy of 77.7% (95% confidence interval, 40.2%-91.7%) against hospitalization for gastroenteritis. Vaccine efficacy was 84.5% (95% confidence interval, 23.4%-96.9%) against confirmed cases of rotavirus infection. Vaccination was effective in this high-burden setting.

Improvement in rheumatic fever and rheumatic heart disease management and prevention using a health centre-based continuous quality improvement approach

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.

Injury prevention through employment as a priority for wellbeing among Aboriginal people in remote Australia

ISSUE ADDRESSED Injuries lead to more hospitalisations and lost years of healthy life for Aboriginal people than any other cause. However, they are often overlooked in discussion of relieving Aboriginal disadvantage. METHODS Four Aboriginal communities with diverse geography, culture and service arrangements participated in the Interplay Wellbeing project. In each community, Aboriginal researchers conducted focus groups and interviews arranged through Aboriginal organisations to explore wellbeing. A total of 84 participants contributed to 14 focus groups and eight interviews, which were recorded, transcribed and coded. This article reports on injury and possibilities for prevention, unanticipated themes raised in discussions of wellbeing. RESULTS Interpersonal violence, injury and imprisonment emerged as themes that were linked with employment and wellbeing. Employment in Aboriginal ranger programs provides meaningful activity, which strengthens peoples identity and cultural integrity. This can avert interpersonal violence through empowering women and reducing alcohol access and consumption. CONCLUSION Ranger programs may provide a much-needed opportunity to control escalating rates of injury for Aboriginal people in remote communities. SO WHAT?: The manifold benefits of Aboriginal ranger programs include reducing violence and its injury and criminal justice consequences.

Tackling antimicrobial resistance globally

In Australia, Indigenous communities bear a disproportionate burden of infectious diseases. This burden arises on a background of overcrowding, poorly built and maintained water and sanitation infrastructure, and colonisation of companion animals by human pathogens. The delivery of biomedically oriented health services leads to frequent use of broad spectrum antibiotics, promoting the development of multiresistant pathogens.

Absolute cardiovascular disease risk and lipid-lowering therapy among Aboriginal and Torres Strait Islander Australians

369 TO THE EDITOR: Calabria and colleagues report that, overall, 9.8% of Aboriginal and Torres Strait Islander adults are at high absolute cardiovascular disease (CVD) risk, reflecting how poorly Australia supports the social and cultural determinants of health for the First Australians. However, this is a different nuance from their statement: “Absolute CVD risk is high among Aboriginal and Torres Strait Islander people”. Aboriginal and Torres Strait Islander people have median age of 23 years, and only 1.1% of those in the 18e24 age group are at high risk.

Qualitative Evaluation of a Complex Intervention to Improve Rheumatic Heart Disease Secondary Prophylaxis.

Background Rheumatic heart disease is a high‐burden condition in Australian Aboriginal communities. We evaluated a stepped‐wedge, community, randomized trial at 10 Aboriginal communities from 2013 to 2015. A multifaceted intervention was implemented using quality improvement and chronic care model approaches to improve delivery of penicillin prophylaxis for rheumatic heart disease. The trial did not improve penicillin adherence. This mixed‐methods evaluation, designed a priori, aimed to determine the association between methodological approaches and outcomes. Methods and Results An evaluation framework was developed to measure the success of project implementation and of the underlying program theory. The program theory posited that penicillin delivery would be improved through activities implemented at clinics that addressed elements of the chronic care model. Qualitative data were derived from interviews with health‐center staff, informants, and clients; participant observation; and project officer reports. Quantitative data comprised numbers and types of “action items,” which were developed by participating clinic staff with project officers to improve delivery of penicillin injections. Interview data from 121 health‐center staff, 22 informants, and 72 clients revealed barriers to achieving the trials aims, including project‐level factors (short trial duration), implementation factors (types of activities implemented), and contextual factors (high staff turnover and the complex sociocultural environment). Insufficient actions were implemented addressing “self‐management support” and “community linkage” streams of the chronic care model. Increased momentum was evident in later stages of the study. Conclusions The program theory underpinning the study was sound. The limited impact made by the study on adherence was attributable to complex implementation challenges.

Australian Indigenous Land Management, Ecological Knowledge and Languages for Conservation

Many Indigenous Australians hold cultural, ecological and language knowledge, but common representations of Indigenous Australians focus on social disadvantage and poor comparisons with other Australians in education, employment and health. Indigenous Land Management works with Indigenous people’s cultural, ecological and language expertise, employing Indigenous people in activities contributing to biodiversity conservation. The Interplay research surveyed 841 Indigenous people in remote communities. Those employed in land management reported greater participation in cultural activities, language knowledge, and belief that their land was looked after. These related assets provide an opportunity for policy approaches based on Indigenous people’s strengths and contribution to Australia.

Response to Editorial: Children, poverty and health promotion in Australia

Your recent editorial ‘Children, poverty and health promotion in Australia’ highlighted opportunities for Australia to promote the health of future generations by ensuring the needs of children and families are prioritised. Missing in the case studies, even when the case was a woman with four children under six and another in utero, was mention of the key preventive intervention to improve childwellbeing: contraception.
