mHealth Person-centred Self-care Support for Homebound Older Adults: A Hybrid Effectiveness-implementation Study

The aim of the study is to evaluate the effectiveness and implementation of the mobile health (mHealth)-assisted, person-centred care (PCC) self-care support programme for homebound older adults. The researcher will compare PCC approach to a conventional care provider-led model. Participants (n = 130) will receive the intervention of six bi-weekly WhatsApp video call sessions over three months with nurse case managers (NCMs).

About this study

This hybrid effectiveness-implementation, cluster-randomized controlled trial evaluates a mHealth-assisted, PCC self-care support programme for homebound older adults in Hong Kong. Participants (n = 130) receive six bi-weekly WhatsApp video call sessions with NCMs over three months. The study compares a PCC-based approach with a conventional provider-led model. Effectiveness outcomes include self-efficacy, functional independence, and psychosocial well-being. Implementation is assessed using the RE-AIM framework. Findings will inform scalable, digital health interventions for aging populations, improving functional independence, self-care engagement, and healthcare accessibility for homebound older adults.
