Effects of telehealth interventions on the caregiver burden and mental health for caregivers of people with dementia: a systematic review and meta-analysis.

Objectives: To systematically evaluate the effects of telehealth interventions on the caregiver burden and mental health of caregivers for people with dementia (PWD). Method: Relevant randomized controlled trials (RCTs) of telehealth interventions on caregivers were extracted from nine electronic databases (PubMed, The Cochrane Library, Web of Science, Embase, CINAHL, SinoMed, CNKI, WanFang, and VIP). The retrieval time was from inception to 26 July 2023. Results: Twenty-two articles with 2132 subjects were included in the final analysis. The meta-analysis demonstrated that telehealth interventions exerted a significant effect in reducing caregiver burden (SMD: −0.14, 95 % CI: −0.25, −0.02, p = 0.02), depression (SMD = −0.17; 95%CI: −0.27, −0.07, p < 0.001) and stress (SMD = −0.20, 95%CI: −0.37, −0.04, p = 0.01). However, no statistically significant effect was observed on anxiety (SMD = −0.12, 95%CI: −0.27, 0.03, p = 0.12). Moreover, subgroup analysis showed that tailored interventions were associated with more evident reductions in depression (SMD = −0.26; 95%CI: −0.40, −0.13, p < 0.001) than standardized interventions (SMD = −0.08; 95%CI: −0.22, 0.06, p = 0.25). In addition, telehealth was effective in relieving depression in Internet-based (SMD = −0.17, 95%CI: −0.30, −0.03, p = 0.01) and Telephone-based group (SMD = −0.18, 95%CI: −0.34, −0.02, p = 0.03), while there was no significant difference in the Internet and Telephone-based group (SMD = −0.18, 95%CI: −0.54, 0.18, p = 0.32). Conclusion: Telehealth could effectively reduce the burden and relieve the depression and stress of caregivers of PWD, while its effect on anxiety requires further research. Overall, telehealth has potential benefits in dementia care. [ABSTRACT FROM AUTHOR]
