Intervention working group (innovation, recipients and facilitation)
An Intervention Working Group (IWG) was convened with an initial focus on reviewing the EDDIE pilot intervention and identifying requirements for scaling up to multi-site implementation. The goal was to ensure the feasibility and scalability of the project. There was an expectation that a level of adaptation would be required for the participating RAC homes, given the mix of metropolitan and regional locations, varied home sizes, and the different populations served. Further, shifting from small scale pilot studies in single sites to implementation across multiple sites, with a different aged care provider from the pilot phase required consideration.The initial convening of the IWG included investigators involved in the pilot intervention, those from the participating aged care provider, and investigators able to provide implementation science expertise and clinical expertise, covering a range of perspectives. The university-based study team responsible for implementing the trial were also part of the IWG. See Table Intervention working group participantsThe MRC guide states that a key step in scaling up complex interventions is the “deconstruction” of the components of an intervention, and an agreement on what variation is acceptable and what variation is prohibited [All intervention refinements (from pilot to trial protocol) were led by the study team, with input from the aged care provider and reviewed by the IWG against the program logic (Additional file
