Abstract

caregivers toolkit older adults partnering cognitive impairment carers delirium prevention
Background: Delirium, a common, serious and often preventable complication in older hospitalised adults, contributes to significant health and social care costs. Carers are uniquely positioned to identify early signs and support delirium prevention. The Prevention & Early Delirium Identification Carer Toolkit (PREDICT), a novel model of care designed to educate carers about delirium management and prevention strategies, enables them to actively participate in the care and recovery of their person. Developed through a comprehensive literature review, a co-designed eDelphi and pilot study, PREDICT demonstrated acceptability and feasibility. Aims: To evaluate the effectiveness, implementation and cost-benefit of a PREDICT in hospital settings. Method: A stepped-wedge cluster randomised controlled trial (SW-cRCT), consisting of a cohort study, healthcare service evaluation, and process evaluation. The study will assess carer and staff knowledge of delirium, carer care giving stress, health service outcomes (e.g., incidence, length of stay, readmissions) and cost-benefit. Discussion: PREDICT is a scalable, person-centred approach that supports both patients and carers, with the potential to embed best-practice delirium management into routine healthcare. Public and Patient Involvement: This study was developed in consultation with older adults, carers and healthcare staff. Two consumer representatives joined the project steering committee and contributed to shaping the research question, refining the study protocol and selecting outcome measures relevant to families and healthcare staff. Carers were involved in reviewing participant information sheets and the PREDICT website, providing feedback to ensure clarity and accessibility. Results will be shared with participants and the wider community through plain-language summaries and public presentations. Trial Registration: Australian and New Zealand Clinical trial: ACTRN12625000705482 registered on the 3rd of July 2025.
