A nurse-led multicentre randomized controlled trial on effectiveness and cost-effectiveness of Chinese iSupport for dementia program: A study protocol

Aims: To describe a nurse-led multicentre randomized controlled trial protocol developed to evaluate the effectiveness and cost-effectiveness of a Chinese iSupport for Dementia program in Australia and Greater China including mainland China, Taiwan, Hong Kong and Macau. Design: A multicentre randomized controlled trial following the SPIRIT checklist. Methods: Participants in the study will be recruited from Australia and Greater China and will be randomly assigned to the intervention group or the usual care group. Interventions will include self-learning of the iSupport program, virtual peer support and nurse program facilitator support for 6 months. Primary outcome measures will be the 12-Item Short-Form Health Survey. Secondary outcome measures will include: Revised Scale for Caregiving Self-efficacy; Quality of Social Support Scale; Revised Memory and Behaviour Problem Checklist; the Quality of Life in Alzheimer's Disease-Proxy; usages of care services; and cost-effectiveness of the intervention. Outcomes will be measured at baseline, 6 months and 9 months from the baseline. Caregivers' experiences of the peer support will be explored. This project was funded by the National Foundation for Australia-China Relations, Australian Government (Project ID: NFACR216). The total amount is $440,000 Australian dollars (or £ 236,231). Discussion: Approximately, 20% of people living with dementia in the world live in Australia and Greater China. Older Chinese are usually cared for by family caregivers at home due to the influence of Confucianism. However, free and online psychoeducation programs for this large cohort of caregivers are not available or accessible. The World Health Organization iSupport for Dementia is an evidence-based online psychoeducation program for caregivers. Implementing a culturally adapted Chinese iSupport program will address this gap in supporting caregivers. Impact: This study will provide research evidence on effectiveness and cost-effectiveness of an online psychoeducation program for caregivers. Findings will inform policy and practice development.
