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

Enhanced support for adherence to rheumatic heart disease prophylaxis for children in the public health system in Uganda (CAMPS): a pragmatic randomised trial

BACKGROUND

Secondary antibiotic prophylaxis is the only intervention known to prevent rheumatic heart disease progression, yet delivery of prophylaxis at scale in low-resource settings has proven challenging, undermining many global programmes. We sought to assess whether enhanced prophylaxis support for rheumatic heart disease, administered through community health workers in the public health system, was feasible and a scalable model.

METHODS

The CAMPS trial was a pragmatic randomised trial of prophylaxis supports integrated into routine care in Eastern Uganda. Children and adolescents with rheumatic heart disease who were aged 5-17 years were randomly assigned (1:1) using permuted block randomisation to either usual care or enhanced support. Enhanced support consisted of case managers and peer groups. Participants and providers were not masked to treatment assignment due to the study design. Children were followed up for 12 months to compare the primary outcome of prophylaxis adherence, measured as a continuous variable of days covered, using a modified intention-to-treat analysis principle. Secondary outcomes were treatment satisfaction, and patient and caregiver health-related quality of life scores. This trial is registered at ClinicalTrials.gov, NCT05502042, and has been completed.

FINDINGS

Between Aug 9, 2022, and Aug 9, 2023, 208 individuals were enrolled in the study and included in the analysis. 104 (50%) individuals were randomly assigned to the usual care group and 105 (50%) to the enhanced support group; one participant in the usual care group was excluded from the primary analysis as they died before the first injection, meaning that 103 participants were analysed in the usual care group. 121 (58%) participants were female and 87 (42%) were male. After 12 months, mean adherence was 80·0% (SD 19·0) for those receiving usual care, compared with 98·2% (7·1) for those receiving enhanced support (estimated mean difference in adherence of 18·2%, 95% CI 14·4-22·1; p<0·0001). No significant differences were found between groups in treatment satisfaction (mean between-group difference of 0·1 points [95% CI -1·9 to 2·1] at 12 months) or quality of life (2·3 [-1·1 to 5·8] for patient score; 1·3 [-1·6 to 4·1] for caregiver score).

INTERPRETATION

The integration of community health workers into rheumatic heart disease supports within the public health system provides an effective and likely scalable model to improve outcomes for children with rheumatic heart disease in low-resource settings. Further research should examine scale-up and scale-out of these strategies, formally explore cost, and rigorously partner with diverse groups of patients to shape adaptations to this design and ensure appropriateness for all groups affected by rheumatic heart disease.

Trimodal skin health programme for childhood impetigo control in remote Western Australia (SToP): a cluster randomised, stepped-wedge trial

BACKGROUND

Skin infections affect physical health and, through stigma, social-emotional health. When untreated, they can cause life-threatening conditions. We aimed to assess the effect of a holistic, co-designed, region-wide skin control programme on the prevalence of impetigo.

METHODS

The SToP (See, Treat, and Prevent Skin Sores and Scabies) trial is a pragmatic, open-cohort, stepped-wedge cluster randomised trial involving participants aged 0-18 years in nine remote communities of the Kimberley, Western Australia. The trial involves programmatic interventions in three domains: See (skin checks and skin infection recognition training), Treat (skin infection treatment training, sulfamethoxazole-trimethoprim for impetigo, and ivermectin for scabies), and Prevent (co-designed health promotion and environmental health). Four clusters, defined as pragmatic aggregations of communities, were randomised in two steps to progressively receive the activities during ten visits. The primary outcome was the proportion of school-aged children (aged 5-9 years) with impetigo. We adopted an intention-to-treat analysis and compared the intervention with the control (usual care before the start of intervention) states to derive a time and cluster averaged effect using Bayesian modelling. This study is registered with Australian New Zealand Clinical Trials Registry, ACTRN12618000520235.

FINDINGS

Between Sept 19, 2018, and Nov 22, 2022, 915 children were consented and 777 (85%) had skin checks performed on at least one of ten possible visits between May 5, 2019, and Nov 22, 2022. Of the participants, 448 (58%) of 777 were aged 5-9 years at one or more of the visit timepoints and were eligible for primary outcome assessment. A decline in impetigo occurred across all clusters, with the greatest decline during the observational period of baseline skin checks before commencement of the interventional trial activities activities. The mean (95% credible interval) for the conditional posterior odds ratio for observing impetigo in the intervention compared with the control period was 1·13 (0·71-1·70). The probability that the intervention reduced the odds of observing impetigo was 0·33.

INTERPRETATION

A decreased prevalence of impetigo during the observational period before the commencement of trial activities was sustained across the trial, attributable to the trimodal skin health initiative. Although the prevalence of impetigo reduced, there is no direct evidence to attribute this to the individual effects of the trial activities. The wholistic approach inclusive of skin checks collectively contributed to the sustained reduction in impetigo.

Process evaluation of a randomised controlled trial intervention designed to improve rehabilitation services for Aboriginal Australians after brain injury: the Healing Right Way Trial

BACKGROUND

Healing Right Way (HRW) aimed to improve health outcomes for Aboriginal Australians with stroke or traumatic brain injury by facilitating system-level access to culturally secure rehabilitation services. Using a stepped-wedge randomised controlled trial (RCT) design (ACTRN12618000139279, 30/01/2018), a two-pronged intervention was introduced in four rural and four urban hospitals, comprising 1.Cultural security training (CST) for staff and 2.Training/employment of Aboriginal Brain Injury Coordinators (ABIC) to support Aboriginal patients for 6-months post-injury. Three-quarters of recruited patients lived rurally. The main outcome measure was quality-of-life, with secondary outcomes including functional measures, minimum processes of care (MPC); number rehabilitation occasions of service received, and improved hospital experience. Assessments were undertaken at baseline, 12- and 26-weeks post-injury. Only MPCs and hospital experience were found to improve among intervention patients. We report on the process evaluation aiming to support interpretation and translation of results.

METHODS

Using mixed methods, the evaluation design was informed by the Consolidated Framework for Implementation Research. Data sources included minutes, project logs, surveys, semi-structured interviews, and observations. Four evaluation questions provided a basis for systematic determination of the quality of the trial. Findings from separate sources were combined to synthesise the emerging themes that addressed the evaluation questions. Three components were considered separately: the trial process, CST and ABIC.

RESULTS

The complex HRW trial was implemented to a satisfactory level despite challenging setting factors, particularly rural-urban system dynamics. Patient recruitment constraints could not be overcome. The vulnerability of stepped-wedge designs to time effects influenced recruitment and trial results, due to COVID. Despite relatively high follow-up, including to rural/remote areas, data points were reduced. The lack of culturally appropriate assessment tools influenced the quality/completeness of assessment data. The ABIC role was deemed feasible and well-received. The CST involved complex logistics, but rated highly although online components were often incomplete. Project management was responsive to staff, patients and setting factors.

CONCLUSIONS

Despite mostly equivocal results, the ABIC role was feasible within mainstream hospitals and the CST was highly valued. Learnings will help build robust state-wide models of culturally secure rehabilitation for Aboriginal people after brain injury, including MPC, workforce, training and follow-up.

Preventive Interventions to Reduce the Burden of Rheumatic Heart Disease in Populations at Risk: A Systematic Review

BACKGROUND

Rheumatic heart disease (RHD) is a devastating yet preventable condition that disproportionately affects low-middle-income countries and indigenous populations in some high-income countries. Various preventive interventions have been implemented across the globe, but evidence for the effectiveness of these measures in reducing the incidence or prevalence of acute rheumatic fever and RHD is scattered. This systematic review aims to assess the effectiveness of preventive interventions and identify the strategies used to reduce the burden of RHD.

METHODS AND RESULTS

A comprehensive search was conducted to identify relevant studies on RHD prevention interventions including interventions for primordial, primary, and secondary prevention. Effectiveness measures for the interventions were gathered when available. The findings indicate that school-based primary prevention services targeting the early detection and treatment of Group A Streptococcus pharyngitis infection with penicillin have the potential to reduce the incidence of Group A Streptococcus pharyngitis and acute rheumatic fever. Community-based programs using various prevention strategies also reduced the burden of RHD. However, there is limited evidence from low-middle-income countries and a lack of rigorous evaluations reporting the true impact of the interventions. Narrative synthesis was performed, and the methodological quality appraisal was done using the Joanna Briggs Institute critical appraisal tools.

CONCLUSIONS

This systematic review underscores the importance of various preventive interventions in reducing the incidence and burden of Group A Streptococcus pharyngitis, acute rheumatic fever, and RHD. Rigorous evaluations and comprehensive analyses of interventions are necessary for guiding effective strategies and informing public health policies to prevent and reduce the burden of these diseases in diverse populations.

Producing knowledge together: a participatory approach to synthesising research across a large-scale collaboration in Aboriginal and Torres Strait Islander health

BACKGROUND

Despite that stakeholder participation in evidence synthesis could result in more useful outcomes, there are few examples of processes that actively involve them in synthesis work. Techniques are needed that engage diverse stakeholders as equal partners in knowledge co-production. The aims of this paper are to describe an innovative participatory process of synthesising a large body of academic research products and compare the findings of the participatory process against two traditional approaches to synthesis: a rapid review and a structured review.

METHODS

First, a rapid synthesis of all research outputs (n = 86) was conducted by researchers with in-depth knowledge of the collaboration's research. Second, a team of researchers and service providers conducted a structured synthesis of seventy-eight peer-reviewed articles and reports generated by the collaboration. Fifty-five publications were brought forward for further synthesis in part three, a facilitated participatory synthesis. Finally, we explored the value added by the participatory method by comparing findings generated across the three synthesis approaches.

RESULTS

Twelve researchers and 11 service providers/policy partners-8 self-identified as Aboriginal and/or Torres Strait Islander-participated in two facilitated workshops (totalling 4 h). Workshop activities engaged participants in reviewing publication summaries, identifying key findings, and evoked review, discussion and refinement. The process explicitly linked experiential knowledge to citations of academic research, clearly connecting the two knowledge types. In comparing the findings generated across all three methods we found mostly consistencies; the few discrepancies did not contradict but gave deeper insights into statements created by the other methods. The participatory synthesis generated the most, detailed, and unique findings, and contextual insights about the relevance of the key messages for practice.

CONCLUSION

The participatory synthesis engaged stakeholders with diverse backgrounds and skillsets in synthesising a large body of evidence in a relatively short time. The participatory approach produced findings comparable to traditional synthesis methods while extending knowledge and identifying lessons most relevant for the participants who, ultimately, are the end users of the research. This process will interest other large-scale research collaborations seeking to engage stakeholders in evidence synthesis.

Exploring the Reported Strengths and Limitations of Aboriginal and Torres Strait Islander Health Research: A Narrative Review of Intervention Studies

High quality intervention research is needed to inform evidence-based practice and policy for Aboriginal and Torres Strait Islander communities. We searched for studies published from 2008-2020 in the PubMed database. A narrative review of intervention literature was conducted, where we identified researcher reported strengths and limitations of their research practice. A total of 240 studies met inclusion criteria which were categorised as evaluations, trials, pilot interventions or implementation studies. Reported strengths included community engagement and partnerships; sample qualities; Aboriginal and Torres Strait Islander involvement in research; culturally appropriate and safe research practice; capacity building efforts; providing resources or reducing costs for services and communities; understanding local culture and context; and appropriate timelines for completion. Reported limitations included difficulties achieving the target sample size; inadequate time; insufficient funding and resources; limited capacity of health workers and services; and inadequate community involvement and communication issues. This review highlights that community consultation and leadership coupled with appropriate time and funding, enables Aboriginal and Torres Strait Islander health intervention research to be conducted. These factors can enable effective intervention research, and consequently can help improve health and wellbeing outcomes for Aboriginal and Torres Strait Islander people.

Bridging the gap between science and indigenous cosmologies: Rheumatic Heart Disease Champions4Change

Australia has articulated a commitment to eliminate rheumatic heart disease (RHD) by 2031. Business as usual will not achieve this goal. Diverse sectors need to work together in implementing complementary strategies towards this ambitious target. Rheumatic Heart Disease Australia’s ‘Champions4Change’ program is one important element that provides a novel and vital approach. Champions4Change is a culturally safe program of people living with acute rheumatic fever (ARF) and rheumatic heart disease (RHD). The Champions support each other, advocate for ending RHD, design education and awareness programs and inform resource and program development through their lived experiences. New approaches that acknowledge the complex and challenging environments in which ARF/RHD exist are required to eliminate RHD and improve care for those living with ARF/RHD. Approaches taken by the program include local engagement, improved capacity and opportunities for Champions and their communities to make self-determined decisions based on culturally informed information. This paper highlights success stories using culture and locally appropriate approaches to improve community knowledge and awareness of RHD. We describe the rationale, development and purpose of Champions4Change, illustrating how this is far more than a peer-support group, and provides benefits for health services and researchers, as well as empowering community members.

Evaluation of a Community-Led Program for Primordial and Primary Prevention of Rheumatic Fever in Remote Northern Australia

Environmental factors including household crowding and inadequate washing facilities underpin recurrent streptococcal infections in childhood that cause acute rheumatic fever (ARF) and subsequent rheumatic heart disease (RHD). No community-based 'primordial'-level interventions to reduce streptococcal infection and ARF rates have been reported from Australia previously. We conducted a study at three Australian Aboriginal communities aiming to reduce infections including skin sores and sore throats, usually caused by Group A Streptococci, and ARF. Data were collected for primary care diagnoses consistent with likely or potential streptococcal infection, relating to ARF or RHD or related to environmental living conditions. Rates of these diagnoses during a one-year Baseline Phase were compared with a three-year Activity Phase. Participants were children or adults receiving penicillin prophylaxis for ARF. Aboriginal community members were trained and employed to share knowledge about ARF prevention, support reporting and repairs of faulty health-hardware including showers and provide healthcare navigation for families focusing on skin sores, sore throat and ARF. We hypothesized that infection-related diagnoses would increase through greater recognition, then decrease. We enrolled 29 participants and their families. Overall infection-related diagnosis rates increased from Baseline (mean rate per-person-year 1.69 [95% CI 1.10-2.28]) to Year One (2.12 [95% CI 1.17-3.07]) then decreased (Year Three: 0.72 [95% CI 0.29-1.15]) but this was not statistically significant (p = 0.064). Annual numbers of first-known ARF decreased, but numbers were small: there were six cases of first-known ARF during Baseline, then five, 1, 0 over the next three years respectively. There was a relationship between household occupancy and numbers (p = 0.018), but not rates (p = 0.447) of infections. This first Australian ARF primordial prevention study provides a feasible model with encouraging findings.

Improving the well-being for young people living with rheumatic heart disease: A peer support pilot program through Danila Dilba Health Service

ISSUE ADDRESSED

Aboriginal and Torres Strait Islander peoples in Australia have an inequitable burden of acute rheumatic fever (ARF) and rheumatic heart disease (RHD), concentrated among young people and necessitating ongoing medical care during adolescence. There is an unmet need for improved well-being and support for these young people to complement current biomedical management.

METHODS

This pilot program initiative aimed to determine the suitability and appropriate format of an ongoing peer support program to address the needs of young people living with RHD in urban Darwin.

RESULTS

Five participants took part in three sessions. Findings demonstrated the peer-support setting was conducive to offering support and enabled participants to share their experiences of living with RHD with facilitators and each other. Satisfaction rates for each session, including both educational components and support activities, were high.

CONCLUSIONS

Learnings from the pilot program can inform the following elements of an ongoing peer-support program: characteristics of co-facilitators and external presenters; program format and session outlines; possible session locations; and resourcing. SO WHAT?: Peer support programs for chronic conditions have demonstrated a wide range of benefits including high levels of satisfaction by participants, improved social and emotional well-being and reductions in patient care time required by health professionals. This pilot program demonstrates the same benefits could result for young people living with RHD.

Improving primary prevention of acute rheumatic fever in Australia: consensus primary care priorities identified through an eDelphi process

OBJECTIVES

To establish the priorities of primary care providers to improve assessment and treatment of skin sores and sore throats among Aboriginal and Torres Strait Islander people at risk of acute rheumatic fever (ARF) and rheumatic heart disease (RHD).

DESIGN

Modified eDelphi survey, informed by an expert focus group and literature review.

SETTING

Primary care services in any one of the five Australian states or territories with a high burden of ARF.

PARTICIPANTS

People working in any primary care role within the last 5 years in jurisdiction with a high burden of ARF.

RESULTS

Nine people participated in the scoping expert focus group which informed identification of an access framework for subsequent literature review. Fifteen broad concepts, comprising 29 strategies and 63 different actions, were identified on this review. These concepts were presented to participants in a two-round eDelphi survey. Twenty-six participants from five jurisdictions participated, 16/26 (62%) completed both survey rounds. Seven strategies were endorsed as high priorities. Most were demand-side strategies with a focus on engaging communities and individuals in accessible, comprehensive, culturally appropriate primary healthcare. Eight strategies were not endorsed as high priority, all of which were supply-side approaches. Qualitative responses highlighted the importance of a comprehensive primary healthcare approach as standard of care rather than disease-specific strategies related to management of skin sores and sore throat.

CONCLUSION

Primary care staff priorities should inform Australia's commitments to reduce the burden of RHD. In particular, strategies to support comprehensive Aboriginal and Torres Strait Islander primary care services rather than an exclusive focus on discrete, disease-specific initiatives are needed.

Formative evaluation of a community-based approach to reduce the incidence of Strep A infections and acute rheumatic fever

OBJECTIVES

To explore the acceptability of a novel, outreached-based approach to improve primary and primordial prevention of Strep A skin sores, sore throats and acute rheumatic fever in remote Aboriginal communities.

METHODS

A comprehensive prevention program delivered by trained Aboriginal Community Workers was evaluated using approximately fortnightly household surveys about health and housing and clinical records.

RESULTS

Twenty-seven primary participants from three remote Aboriginal communities in the Northern Territory consented, providing 37.8 years of retrospective baseline data and 18.5 years of prospective data during the study period. Household members were considered to be secondary participants. Five Aboriginal Community Workers were trained and employed, delivering a range of supports to households affected by acute rheumatic fever including environmental health support and education. Clinical record audit and household self-report of Strep A infections were compared. No association between clinical- and self-report was identified.

CONCLUSIONS

Ongoing participation suggests this outreach-based prevention program was acceptable and associated with improved reporting of household maintenance issues and awareness of prevention opportunities for Strep A infections. Implications for public health: Biomedical, clinic-based approaches to the management of Strep A infections in remote communities can be usefully augmented by outreach-based supports delivered by Aboriginal Community Workers responding to community needs.

The Global Impact of Rheumatic Heart Disease

PURPOSE OF REVIEW

Rheumatic heart disease (RHD) is a neglected disease of poverty, which presents challenges for patients, communities, and health systems. These effects are magnified in low resource countries, which bear the highest disease burden. When considering the impact of RHD, it is imperative that we widen our lens in order to better understand how RHD impacts the over 40 million people currently living with this preventable condition and their communities. We aimed to perform an updated literature review on the global impact of RHD, examining a broad range of aspects from disease burden to impact on healthcare system to socioeconomic implications.

RECENT FINDINGS

RHD accounts for 1.6% of all cardiovascular deaths, resulting in 306,000 deaths yearly, with a much higher contribution in low- and middle-income countries, where 82% of the deaths occurred in 2015. RHD can result in severe health adverse outcomes, markedly heart failure, arrhythmias, stroke and embolisms, and ultimately premature death. Thus, preventive, diagnostic and therapeutic interventions are required, although insufficiently available in undersourced settings. As examples, anticoagulation management is poor in endemic regions - and novel oral anticoagulants cannot be recommended - and less than 15% of those in need have access to interventional procedures and valve replacement in Africa. RHD global impact remains high and unequally distributed, with a marked impact on lower resourced populations. This preventable disease negatively affects not only patients, but also the societies and health systems within which they live, presenting broad challenges and high costs along the pathway of prevention, diagnosis, and management.

Subcutaneous administration of benzathine benzylpenicillin G has favourable pharmacokinetic characteristics for the prevention of rheumatic heart disease compared with intramuscular injection: a randomized, crossover, population pharmacokinetic study in healthy adult volunteers

BACKGROUND

Benzathine penicillin G has been used as monthly deep intramuscular (IM) injections since the 1950s for secondary prevention of acute rheumatic fever and rheumatic heart disease (RHD). Injection frequency and pain are major programmatic barriers for adherence, prompting calls for development of better long-acting penicillin preparations to prevent RHD. We hypothesized that subcutaneous (SC) administration of benzathine penicillin G could delay penicillin absorption when compared with IM injections.

METHODS

To compare the pharmacokinetic profile and tolerability of benzathine penicillin G according to different routes of administration, 15 healthy males participated in a randomized crossover study to receive benzathine penicillin G by either SC or IM routes, with a 10 week washout period before the second dose by the alternative route. Ultrasound guidance confirmed injection location. Penicillin concentrations and pain scores were measured for 6 weeks following injections.

RESULTS

SC administration was well tolerated with no significant differences in pain scores. Following SC injection, the principal absorption half-life (95% CI) was 20.1 (16.3-29.5) days and 89.6% (87.1%-92.0%) of the drug was directed via this pathway compared with 10.2 (8.6-12.5) days and 71.3% (64.9%-77.4%) following IM administration. Lower peak and higher trough penicillin concentrations resulted following SC injection. Simulations demonstrated that SC infusion of higher doses of benzathine penicillin G could provide therapeutic penicillin concentrations for 3 months.

CONCLUSIONS

SC administration of benzathine penicillin G is safe and significantly delays penicillin absorption. High-dose benzathine penicillin G via the SC route would fulfil many product characteristics required for the next generation of longer-acting penicillins for use in RHD.

Rheumatic heart disease in Indigenous young peoples

Indigenous children and young peoples live with an inequitable burden of acute rheumatic fever and rheumatic heart disease. In this Review, we focus on the epidemiological burden and lived experience of these conditions for Indigenous young peoples in Australia, New Zealand, and Canada. We outline the direct and indirect drivers of rheumatic heart disease risk and their mitigation. Specifically, we identify the opportunities and limitations of predominantly biomedical approaches to the primary, secondary, and tertiary prevention of disease among Indigenous peoples. We explain why these biomedical approaches must be coupled with decolonising approaches to address the underlying cause of disease. Initiatives underway to reduce acute rheumatic fever and rheumatic heart disease in Australia, New Zealand, and Canada are reviewed to identify how an Indigenous rights-based approach could contribute to elimination of rheumatic heart disease and global disease control goals.

Ending rheumatic heart disease in Australia: the evidence for a new approach

■The RHD Endgame Strategy: the blueprint to eliminate rheumatic heart disease in Australia by 2031 (the Endgame Strategy) is the blueprint to eliminate rheumatic heart disease (RHD) in Australia by 2031. Aboriginal and Torres Strait Islander people live with one of the highest per capita burdens of RHD in the world. ■The Endgame Strategy synthesises information compiled across the 5-year lifespan of the End Rheumatic Heart Disease Centre of Research Excellence (END RHD CRE). Data and results from priority research projects across several disciplines of research complemented literature reviews, systematic reviews and narrative reviews. Further, the experiences of those working in acute rheumatic fever (ARF) and RHD control and those living with RHD to provide the technical evidence for eliminating RHD in Australia were included. ■The lived experience of RHD is a critical factor in health outcomes. All future strategies to address ARF and RHD must prioritise Aboriginal and Torres Strait Islander people's knowledge, perspectives and experiences and develop co-designed approaches to RHD elimination. The environmental, economic, social and political context of RHD in Australia is inexorably linked to ending the disease. ■Statistical modelling undertaken in 2019 looked at the economic and health impacts of implementing an indicative strategy to eliminate RHD by 2031. Beginning in 2019, the strategy would include: reducing household crowding, improving hygiene infrastructure, strengthening primary health care and improving secondary prophylaxis. It was estimated that the strategy would prevent 663 deaths and save the health care system $188 million. ■The Endgame Strategy provides the evidence for a new approach to RHD elimination. It proposes an implementation framework of five priority action areas. These focus on strategies to prevent new cases of ARF and RHD early in the causal pathway from Streptococcus pyogenes exposure to ARF, and strategies that address the critical systems and structural changes needed to support a comprehensive RHD elimination strategy.

Priorities for improved management of acute rheumatic fever and rheumatic heart disease: analysis of cross-sectional continuous quality improvement data in Aboriginal primary healthcare centres in Australia

Objective This study investigated the delivery of guideline-recommended services for the management of acute rheumatic fever (ARF) and rheumatic heart disease (RHD) in Australian primary healthcare centres participating in the Audit and Best Practice for Chronic Disease (ABCD) National Research Partnership project. Methods ARF and RHD clinical audit data were collected from 63 Aboriginal centres in four Australian jurisdictions using the ABCD ARF/RHD audit tool. Records of up to 30 patients treated for ARF and/or RHD were analysed per centre from the most recent audit conducted between 2009 and 2014. The main outcome measure was a quality of ARF and RHD care composite indicator consisting of nine best-practice service items. Results Of 1081 patients, most were Indigenous (96%), female (61%), from the Northern Territory and Queensland (97%) and <25 years of age (49%). The composite indicator was highest in the 0-14 year age group (77% vs 65-67% in other age groups). Timely injections and provision of client education are important specific areas for improvement. Multiple regression showed age >15 years to be a significant negative factor for several care indicators, particularly for the delivery of long-acting antibiotic injections and specialist services in the 15-24 year age group. Conclusions The results suggest that timely injection and patient education are priorities for managing ARF and RHD, particularly focusing on child-to-adult transition care. What is known about the topic? The burden of rheumatic fever and RHD in some Aboriginal communities is among the highest documented globally. Guideline-adherent RHD prevention and management in primary health care (PHC) settings are critically important to reduce this burden. Continuous quality improvement (CQI) is a proven strategy to improve guideline adherence, using audit cycles and proactive engagement of PHC end users with their own data. Previously, such CQI strategies using a systems approach were shown to improve delivery of ARF and RHD care in six Aboriginal health services (three government and three community controlled). What does this paper add? This paper focuses on the variation across age groups in the quality of ARF and/or RHD care according to nine quality of care indicators across 63 PHC centres serving the Aboriginal population in the Northern Territory, Queensland, South Australia and Western Australia. These new findings provide insight into difference in quality of care by life stage, indicating particular areas for improvement of the management of ARF and RHD at the PHC level, and can act as a baseline for monitoring of care quality for ARF and RHD into the future. What are the implications for practitioners? Management plans and innovative strategies or systems for improving adherence need to be developed as a matter of urgency. PHC professionals need to closely monitor adherence to secondary prophylaxis at both the clinic and individual level. RHD priority status needs to be assigned and recorded as a tool to guide management. Systems strengthening needs to particularly target child-to-adult transition care. Practitioners are urged to keep a quick link to the RHDAustralia website to access resources and guidelines pertaining to ARF and RHD (https://www.rhdaustralia.org.au/arf-rhd-guideline, accessed 3 October 2019). CQI strategies can assist PHC centres to improve the care they provide to patients.

Voices behind the Statistics: A Systematic Literature Review of the Lived Experience of Rheumatic Heart Disease

In Australia, Aboriginal children almost entirely bear the burden of acute rheumatic fever (ARF) which often leads to rheumatic heart disease (RHD), a significant marker of inequity in Indigenous and non-Indigenous health experiences. Efforts to eradicate RHD have been unsuccessful partly due to lack of attention to voices, opinions and understandings of the people behind the statistics. This systematic review presents a critical, interpretive analysis of publications that include lived experiences of RHD. The review approach was strengths-based, informed by privileging Indigenous knowledges, perspectives and experiences, and drawing on Postcolonialism and Critical Race Theory. Fifteen publications were analysed. Nine themes were organised into three domains which interact synergistically: sociological, disease specific and health service factors. A secondary sociolinguistic analysis of quotes within the publications articulated the combined impact of these factors as 'collective trauma'. Paucity of qualitative literature and a strong biomedical focus in the dominant narratives regarding RHD limited the findings from the reviewed publications. Noteworthy omissions included: experiences of children/adolescents; evidence of Indigenous priorities and perspectives for healthcare; discussions of power; recognition of the centrality of Indigenous knowledges and strengths; and lack of critical reflection on impacts of a dominant biomedical approach to healthcare. Privileging a biomedical approach alone is to continue colonising Indigenous healthcare.

SToP (See, Treat, Prevent) skin sores and scabies trial: study protocol for a cluster randomised, stepped-wedge trial for skin disease control in remote Western Australia

INTRODUCTION

Skin is important in Australian Aboriginal culture informing kinship and identity. In many remote Aboriginal communities, scabies and impetigo are very common. Untreated skin infections are painful, itchy and frequently go untreated due to under-recognition and lack of awareness of their potential serious complications. We hypothesise that the skin infection burden in remote Aboriginal communities can be reduced by implementing streamlined training and treatment pathways integrated with environmental health and health promotion activities, tested in the See, Treat, Prevent (SToP skin sores and scabies) trial.

METHODS AND ANALYSIS

SToP will evaluate a skin control programme using a stepped-wedge, cluster randomised trial design with three intervention components (the 'SToP activities'): (1) seeing skin infections (development of training resources implemented within a community dermatology model); (2) treating skin infections (employing the latest evidence for impetigo, and scabies treatment); and (3) preventing skin infections (embedded, culturally informed health promotion and environmental health activities). Four community clusters in the remote Kimberley region of Western Australia will participate. Following baseline data collection, two clusters will be randomly allocated to the SToP activities. At 12 months, the remaining two clusters will transition to the SToP activities. The primary outcome is the diagnosis of impetigo in children (5-9 years) at school-based surveillance. Secondary outcome measures include scabies diagnosis, other child health indicators, resistance to cotrimoxazole in circulating pathogenic bacteria, determining the economic burden of skin disease and evaluating the cost effectiveness of SToP activities.

ETHICS AND DISSEMINATION

This study protocol was approved by the health ethics review committees at the Child and Adolescent Health Service (Approval number RGS0000000584), the Western Australian Aboriginal Health Ethics Committee (Reference number: 819) and the University of Western Australia (Reference RA/4/20/4123). Study findings will be shared with community members, academic and medical communities via publications and presentations, and in reports to funders. Authorship for all publications based on this study will be determined in line with the Uniform Requirements for Manuscripts Submitted to Biomedical Journals published by the International Committee of Medical Journal Editors. Sharing results with organisations and communities who contributed to the study is paramount. The results of the SToP trial will be shared with participants in a suitable format, such as a single summary page provided to participants or presentations to communities, the Kimberly Aboriginal Health Planning Forum Research Subcommittee and other stakeholders as appropriate and as requested. Communication and dissemination will require ongoing consultation with Aboriginal communities to determine appropriate formats.

A cluster of acute rheumatic fever cases among Aboriginal Australians in a remote community with high baseline incidence

OBJECTIVES

We report a cluster of acute rheumatic fever (ARF) cases and the public health response in a high-burden Australian setting.

METHODS

The public health unit was notified of an increase in ARF cases in a remote Australian Aboriginal community. A multi-disciplinary group coordinated the response. Household contacts were screened for ARF or group A Streptococcus (GAS) infection by questionnaire and swab collection, offered an echocardiogram if aged 5-20 years, and intramuscular benzathine benzylpenicillin if aged over one year or if less than one year with impetigo.

RESULTS

Fifteen definite and seven probable ARF cases were diagnosed in the community in July-December 2014 (all-age incidence of definite ARF: 1,473/100,000). The public health response identified two additional cases of ARF. A total of 81 contacts were screened; GAS was detected in 3/76 (4%) throat swabs and 11/24 (46%) skin swabs. Molecular typing revealed high GAS strain diversity.

CONCLUSIONS

The incidence of ARF during this cluster was very high. Carriage and infection with GAS was observed, but no outbreak strain identified. Implications for public health: A national public health guideline has since been developed that includes advice on the investigation of an ARF outbreak/cluster. Sustained efforts with strong community engagement are required to tackle high ARF rates.

Community-based participatory action research on rheumatic heart disease in an Australian Aboriginal homeland: Evaluation of the 'On track watch' project

Strategies to date have been ineffective in reducing high rates of rheumatic heart disease (RHD) in Australian Aboriginal people; a disease caused by streptococcal infections. A remote Aboriginal community initiated a collaboration to work towards elimination of RHD. Based in 'both-way learning' (reciprocal knowledge co-creation), the aim of this study was to co-design, implement and evaluate community-based participatory action research (CBPAR) to achieve this vision. Activities related to understanding and addressing RHD social determinants were delivered through an accredited course adapted to meet learner and project needs. Theory-driven evaluation linking CBPAR to empowerment was applied. Data collection comprised focus groups, interviews, observation, and co-development and use of measurement tools such as surveys. Data analysis utilised process indicators from national guidelines for Aboriginal health research, and outcome indicators derived from the Wallerstein framework. Findings include the importance of valuing traditional knowledges and ways of learning such as locally-meaningful metaphors to explore unfamiliar concepts; empowerment through critical thinking and community ownership of knowledge about RHD and research; providing practical guidance in implementing empowering and decolonising principles / theories. Lessons learned are applicable to next stages of the RHD elimination strategy which must include scale-up of community leadership in research agenda-setting and implementation.

Improving Delivery of Secondary Prophylaxis for Rheumatic Heart Disease in a High-Burden Setting: Outcome of a Stepped-Wedge, Community, Randomized Trial

BACKGROUND

Health system strengthening is needed to improve delivery of secondary prophylaxis against rheumatic heart disease.

METHODS AND RESULTS

We undertook a stepped-wedge, randomized trial in northern Australia. Five pairs of Indigenous community clinics entered the study at 3-month steps. Study phases comprised a 12 month baseline phase, 3 month transition phase, 12 month intensive phase and a 3- to 12-month maintenance phase. Clinics received a multicomponent intervention supporting activities to improve penicillin delivery, aligned with the chronic care model, with continuous quality-improvement feedback on adherence. The primary outcome was the proportion receiving ≥80% of scheduled penicillin injections. Secondary outcomes included "days at risk" of acute rheumatic fever recurrence related to late penicillin and acute rheumatic fever recurrence rates. Overall, 304 patients requiring prophylaxis were eligible. The proportion receiving ≥80% of scheduled injections during baseline was 141 of 304 (46%)-higher than anticipated. No effect attributable to the study was evident: in the intensive phase, 126 of 304 (41%) received ≥80% of scheduled injections (odds ratio compared with baseline: 0.78; 95% confidence interval, 0.54-1.11). There was modest improvement in the maintenance phase among high-adhering patients (43% received ≥90% of injections versus 30% [baseline] and 28% [intensive], P<0.001). Also, the proportion of days at risk in the whole cohort decreased in the maintenance phase (0.28 versus 0.32 [baseline] and 0.34 [intensive], P=0.001). Acute rheumatic fever recurrence rates did not differ between study sites during the intensive phase and the whole jurisdiction (3.0 versus 3.5 recurrences per 100 patient-years, P=0.65).

CONCLUSIONS

This strategy did not improve adherence to rheumatic heart disease secondary prophylaxis within the study time frame. Longer term primary care strengthening strategies are needed.
