Primary care nurses (PCNs) are the second largest workforce in primary care and play a critical role in facilitating access to coordinated care and reducing health disparities. There is renewed interest in team-based primary care as a solution for health workforce challenges. Some team models enable PCNs (ie, nurse practitioners, registered nurses, licensed/registered practical nurses) to leverage one another’s expertise to work to optimal scope; the extent to which this happens depends on multiple context-dependent factors. We will conduct an umbrella review to synthesise and compare international knowledge syntheses focused on scope of practice enactment (ie., roles and activities) of PCNs in primary care.

We will conduct the umbrella review according to the Joanna Briggs Institute methodology, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocol (PRISMA-P) guidelines, and using the Nursing Care Organization Framework as guidance. We will search a wide range of scientific electronic databases and grey literature sources, and consider articles published in English and French by the Organization for Economic Cooperation and Development and designated key partner countries for inclusion, with no publication date limits. Two independent reviewers will screen titles, abstracts and full-text articles, and any disagreements will be resolved through discussion or by a third reviewer. We will use the Risk of Bias Assessment Tool for Systematic Reviews to assess the quality and risk of bias in the included systematic and scoping reviews.

Results will be presented in a PRISMA Scoping Review flow diagram. We will synthesise data from included studies in a detailed literature review table and develop visual aids to communicate the shared and unique roles and activities of PCN scope of practice. We will disseminate the results of the review through peer-reviewed publications and conferences related to this field. Ethics approval is not required.

International consensus guidelines support the initial administration of 30 mL/kg of intravenous fluids for haemodynamic resuscitation of newly diagnosed septic shock. Practice variation exists between the volume of fluids administered and timing of vasopressor commencement. The optimal approach in patients with septic shock is uncertain.

Australasian Resuscitation In Sepsis Evaluation: FLUid or vasopressors In emergency Department Sepsis is a 1000-participant multicentre, randomised, open-label, parallel group clinical trial conducted in patients with septic shock presenting to the emergency department in participating sites in Australia, New Zealand and Ireland. Participants are randomised (1:1) to either restricted fluids and early vasopressors or a larger initial intravenous fluid volume and later vasopressors. The primary outcome is days alive and out of hospital at day 90 postrandomisation. Secondary outcomes are all-cause mortality at day 90, time from randomisation until death (to day 90), days alive and at home at day 90 and ventilator-free, vasopressor-free and renal replacement-free days to day 28 postrandomisation and death or disability at 6-month and 12-month postrandomisation. Health-related quality of life will be assessed at day 180 and 12 months following randomisation.

The study was approved by Northern Sydney Local Health District Human Research Ethics Committee (HREC2020/ETH02874) on 21 January 2021. Patients will be enrolled under a waiver of prior consent. The patient or next-of-kin (or equivalent according to local jurisdiction) is approached at the first available opportunity and given a trial information sheet. According to local approvals, the patient or next-of-kin chooses to either continue in the trial or opt-out/decline continued participation. Results will be disseminated in peer-reviewed journals and presented at academic conferences.

Approximately 1 in 13 Australian children have a neurodevelopmental disability. This project aims to assess the effectiveness and implementation of an online parenting support programme, Parenting Acceptance and Commitment Therapy (PACT) Online, for parents of children with neurodevelopmental disabilities for improving the parent–child relationship and parent and child outcomes.

This hybrid type 1 randomised controlled trial will focus on evaluating intervention effectiveness and understanding the context for implementation. The primary outcome is observed emotional availability within parent–child interactions assessed at postintervention (12 weeks postbaseline) with additional measurement at follow-up (6 months postbaseline). Secondary outcomes include (1) parent-reported emotional availability, (2) parental mindfulness, (3) parent mental health, (4) psychological flexibility, (5) adjustment to child’s disability, (6) health behaviour and (7) regulatory abilities as well as child outcomes of (1) mental health, (2) adaptive behaviour and (3) regulatory abilities. Evaluation of implementation will include an economic evaluation of costs and consequences, and an implementation analysis grounded in the consolidated framework for implementation research with a focus on contextual factors influencing implementation.

Ethical approval has been obtained from the University of Queensland Human Research Ethics Committee (023/HE000040). Dissemination of study outcomes will occur through the appropriate scientific channels. Long-term implementation will be grounded within the implementation analysis and occur in partnership with the partner organisations and consumer engagement panel. This will include releasing the PACT Online intervention as a massive open online course on the edX platform if support for intervention effectiveness and implementation is found.

ACTRN12623000612617; this trial has been registered with the Australian New Zealand Clinical Trials Registry.
