Effects of a video-based mHealth program for homebound older adults : study protocol for a pilot randomized controlled trial

Abstract

Background: Although homebound older adults are among the highest users of hospital services, the existing health and social services that are provided to them in the community are limited and fragmented. This study attempts to bring this group of older adults to providers' attention by designing a health-social-oriented self-care mobile Health (mHealth) program and subjecting it to empirical testing. The aim of this study is to shift the current reactive, cure-oriented approach to a preventive and health-promoting model, empowering homebound older adults to take an active role in their health, be responsive to their care needs, and subsequently improve their holistic health. Methods: This is a pilot randomized controlled trial. The study is supported by 5 community centers with an estimated sample size of 68 subjects. The subjects will be randomly assigned to video-based mHealth or control groups when they (1) are aged 60 or over, (2) go outdoors less than once a week in the current 6 months, (3) live within the service areas, and (4) use a smartphone. Subjects in the video-based mHealth group will receive a 3-month program comprising 2 main interventions: nurse case management supported by a social service team and video messages covering self-care topics, delivered via smartphone. The control group will receive usual care. Data will be collected at 2 time points - pre-intervention (T1) and post-intervention (T2). The primary outcome will be self-efficacy, and secondary outcomes will include health outcomes (activities of daily living, instrumental activities of daily living, and medication adherence), perceived well-being outcomes (quality of life and depression), and health service utilization outcomes (outpatient clinic, emergency room, and hospital admission). Discussion: The current study will add to the knowledge gap in using mHealth supported by a health-social team to enhance quality of life and self-care and meet the needs of these particularly vulnerable older adults.
