IntroductionRotavirus vaccines were introduced into the Australian National Immunisation Program in 2007. Despite this, Northern Territory Indigenous children continue to be hospitalised with rotavirus at a rate more than 20 times higher than non-Indigenous children in other Australian jurisdictions, with evidence of waning protection in the second year of life. We hypothesised that scheduling an additional (third) dose of oral human rotavirus vaccine (Rotarix, GlaxoSmithKline) for children aged 6 to <12 months would improve protection against clinically significant all-cause gastroenteritis.Methods and analysisThis Bayesian adaptive clinical trial will investigate whether routinely scheduling an additional dose of Rotarix for Australian Indigenous children aged 6 to <12 months old confers significantly better protection against clinically important all-cause gastroenteritis than the current two-dose schedule at 2 and 4 months old. There are two coprimary endpoints: (1) seroconversion from baseline serum anti-rotavirus immunoglobulin A (IgA) titre <20 U/mL prior to an additional dose of Rotarix/placebo to serum anti-rotavirus IgA titre >20 U/mL following the administration of the additional dose of Rotarix/placebo and (2) time from randomisation to medical attendance (up to age 36 months old) for which the primary reason is acute gastroenteritis/diarrhoea. Secondary endpoints include the change in anti-rotavirus IgA log titre, time to hospitalisation for all-cause diarrhoea and for rotavirus-confirmed gastroenteritis/diarrhoea, and rotavirus notification. Analysis will be based on Bayesian inference with adaptive sample size.Ethics, registration and disseminationEthics approval has been granted by Central Australian Human Research Ethics Committee (HREC-16-426) and Human Research Ethics Committee of the Northern Territory Department of Health and Menzies School of Health Research (HREC-2016-2658). Study investigators will ensure the trial is conducted in accordance with the principles of the Declaration of Helsinki and with the ICH Guidelines for Good Clinical Practice. Individual participant consent will be obtained. Results will be disseminated via peer-reviewed publication. The trial is registered with Clinicaltrials.gov (NCT02941107) and important modifications to this protocol will be updated.Trial registration numberNCT02941107; Pre-results.

IntroductionChronic heart failure (CHF) is a life-threatening chronic disease characterised by periodic exacerbations and recurrent hospitalisations. In the management of CHF, patient compliance with evidence-based clinical guidelines is essential, but remains difficult practically. The objective of this study is to examine whether an Innovative Telemonitoring Enhanced Care Programme for CHF (ITEC-CHF) improves patients’ compliance, and associated health and economic outcomes.Methods and analysisAn open multicentre randomised controlled trial has been designed. Patients will be recruited and randomised to receive either ITEC-CHF (n=150) or usual care CHF (n=150) for at least 6 months. ITEC-CHF combines usual care and an additional telemonitoring service including remote weight monitoring, structured telephone support and nurse-led collaborative care. The primary outcomes are the compliance rates with the best-practice guidelines for daily weight monitoring. The secondary outcomes include the compliance with other guideline recommendations (health maintenance, medication, diet and exercise), health (health-related quality of life, risk factors, functional capacity and psychological states) and economic outcomes related to the use of healthcare resources such as hospital readmissions and general practitioner/emergency department visits.Ethics and disseminationThe clinical trial has been approved by Peninsula Health Human Research Ethics Committee (HREC Reference: HREC/14/PH/27), Royal Perth Hospital Human Research Ethics Committee (Reference: 15-081) and the Curtin University Human Research Ethics Committee (Reference: HR 181/2014). We will disseminate the final results to the public via conferences and journal publications. A final study report will also be provided to the ethics committees.Trial registration numberRegistered with Australian New Zealand Clinical Trial Registry (ACTRN12614000916640).

IntroductionAccess to high-quality primary healthcare is limited for remote residents in Australia. Increasingly, remote health services are reliant on short-term or ‘fly-in, fly-out/drive-in, drive-out’ health workforce to deliver primary healthcare. A key strategy to achieving health service access equity, particularly evident in remote Australia, has been the development of Aboriginal Community Controlled Health Services (ACCHSs). This study aims to generate new knowledge about (1) the impact of short-term staffing in remote and rural ACCHSs on Aboriginal and Torres Strait Islander communities; (2) the potential mitigating effect of community control; and (3) effective, context-specific evidence-based retention strategies.Methods and analysisThis paper describes a 3-year, mixed methods study involving 12 ACCHSs across three states. The methods are situated within an evidence-based programme logic framework for rural and remote primary healthcare services. Quantitative data will be used to describe staffing stability and turnover, with multiple regression analyses to determine associations between independent variables (population size, geographical remoteness, resident staff turnover and socioeconomic status) and dependent variables related to patient care, service cost, quality and effectiveness. Qualitative assessment will include interviews and focus groups with clinical staff, clinic users, regionally-based retrieval staff and representatives of jurisdictional peak bodies for the ACCHS sector, to understand the impact of short-term staff on quality and continuity of patient care, as well as satisfaction and acceptability of services.Ethics and disseminationThe study has ethics approval from the Human Research Ethics Committee of the Northern Territory Department of Health and Menzies School of Health Research (project number DR03171), Central Australian Human Research Ethics Committee (CA-19-3493), Western Australian Aboriginal Health Ethics Committee (WAAHEC-938) and Far North Queensland Human Research Ethics Committee (HREC/2019/QCH/56393). Results will be disseminated through peer-reviewed journals, the project steering committee and community/stakeholder engagement activities to be determined by each ACCHS.

IntroductionPeople of Ashkenazi Jewish (AJ) ancestry are more likely than unselected populations to have a BRCA1/2 pathogenic variant, which cause a significantly increased risk of breast, ovarian and prostate cancer. Three specific BRCA1/2 pathogenic variants, referred to as BRCA-Jewish founder mutations (B-JFM), account for >90% of BRCA1/2 pathogenic variants in people of AJ ancestry. Current practice of identifying eligible individuals for BRCA testing based on personal and/or family history has been shown to miss at least 50% of people who have one of these variants. Here we describe the protocol of the JeneScreen study—a study established to develop and evaluate two different population-based B-JFM screening programmes, offered to people of Jewish ancestry in Sydney and Melbourne, Australia.Methods and analysisTo rmeasure the acceptability of population-based B-JFM screening in Australia, two screening programmes using different methodologies have been developed. The Sydney JeneScreen programme provides information and obtains informed consent by way of an online tool. The Melbourne JeneScreen programme does this by way of community sessions attended in person. Participants complete questionnaires to measure clinical and psychosocial outcomes at baseline, and for those who have testing, 2 weeks postresult. Participants who decline testing are sent a questionnaire regarding reasons for declining. Participants with a B-JFM are sent questionnaires 12-month and 24-month post-testing. The questionnaires incorporate validated scales, which measure anxiety, decisional conflict and regret, and test-related distress and positive experiences, and other items specifically developed or adapted for the study. These measures will be assessed for each programme and the two population-based B-JFM screening methods will be compared.Ethics and disseminationInstitutional Human Research Ethics Committee approval was obtained from the South Eastern Area Health Service Human Research Ethics Committee: HREC Ref 16/125.Following the analysis of the study results, the findings will be disseminated widely through conferences and publications, and directly to participants in writing.

As part of a larger study, Australian Human Research Ethics Committee (HREC) members and managers were surveyed about their decision-making and views about social research studies with child participants. Responses of 229 HREC members and 42 HREC managers are reported. While most HREC members had received ethical training, HREC training and guidelines specific to research involving children were rare. Most applications involving children had to go through a full ethical review, but few adverse events were reported to HRECs regarding the conduct of the studies. Revisions to study proposals requested by HRECs were mostly related to consent processes and age-appropriate language. One-third of HREC members said that they would approve research on any topic. Most were also concerned that the methodology was appropriate, and the risks and benefits were clearly articulated. Specific training and guidance are needed to increase HREC members’ confidence to judge ethical research with children.
