Effectiveness of a Telecare-Based Intervention Program in Supporting Informal Caregivers of Community-Dwelling Older Adults in Reducing Stress Levels: Randomized Controlled Trial

Clinical Snapshot

Key Findings

• P Value: Self-efficacy: P=.04; Depression: P=.03 (significant between-group differences)

• Effect Size: Not reported - only t-statistics provided

• Primary Outcome: No significant between-group difference in stress levels (primary outcome not achieved)

• Nnt Or Sensitivity: Not calculable from available data

• Confidence Interval: Not reported

Clinical Application

High feasibility given widespread smartphone adoption and existing telehealth infrastructure, though requires basic digital literacy Highly relevant to Australian aged care policy emphasizing aging in place. Aligns with Medicare telehealth items and could complement existing Carer Gateway services. May reduce pressure on residential aged care system Informal caregivers of community-dwelling older adults, particularly those with limited access to traditional support services

Abstract

BACKGROUND: Informal caregivers are essential in supporting community-dwelling older adults, especially as global populations age. However, caregiving responsibilities often result in high stress, depressive symptoms, and diminished quality of life. Traditional support services are fragmented, and many programs overlook caregivers' emotional and informational needs. Telecare-the remote delivery of health and social care via digital technologies-offers a promising approach to provide accessible, personalized, and timely support. OBJECTIVE: This study evaluated the effectiveness of a telecare-based intervention program, developed by a health-social partnership team, in improving psychological well-being and caregiving outcomes among informal caregivers of community-dwelling older adults. We hypothesized that caregivers in the intervention group would show greater improvements in stress, self-efficacy, depression, quality of life, and caregiving burden compared to those receiving usual care. METHODS: A single-blind randomized controlled trial was conducted from January to December 2023, with 75 informal caregivers providing care to older adults (aged ≥60 y) for at least 4 hours per week. Participants were randomized to an intervention group (n=38, 51%) or a control group (n=37, 49%). The 3-month intervention included (1) biweekly online nurse case management supported by a multidisciplinary health-social team, (2) personalized WhatsApp videos on caregiving skills, and (3) a password-protected caregiver website offering resources and peer discussion. The control group attended 6 in-person educational sessions at a community center. Outcomes such as stress, self-efficacy, depression, quality of life, and caregiving burden were measured at baseline and postintervention. RESULTS: Participants had a mean age of 65.5 (SD 9.617) years, and 81.3% (61/74) were female. Baseline characteristics were similar between groups. Compared to controls, the intervention group showed significantly higher self-efficacy (t=1.98; P=.04) and lower depression (t=-2.24; P=.03) at follow-up. Within-group improvements in the intervention group were also observed for stress, depression, self-efficacy, mental quality of life, and caregiving burden. No significant between-group differences were found for stress, quality of life, or caregiving burden. No significant within-group improvements were observed in the control group. CONCLUSIONS: This study provides novel evidence that a digitally delivered, nurse-led telecare program-integrating health and social services-can improve psychological outcomes among informal caregivers. These findings have practical implications for health systems seeking scalable, low-barrier solutions to support caregivers. Telecare models may be a valuable complement to traditional services, enhancing caregiver resilience and promoting aging in place while alleviating long-term strain on institutional care systems.
