Telehealth impact on biomedical, psychosocial, and behavioural outcomes in patients with diabetes older than 50 years: A systematic synthesis without meta-analysis

Abstract

Background Elderly people with diabetes are among high-risk groups that require more attention. With the increasing use of technology in healthcare, much emphasis has been placed on telehealth because of its potential to reduce unnecessary healthcare services consumption. We aimed to review and analyse the evidence of various interventions on the effect of using telehealth on biomedical, behavioural, and psychosocial outcomes in patients with diabetes over 50 years. Methods The search method of this systematic synthesis without meta-analysis was guided by the preferred reporting items for systematic reviews (PRISMA) and the new reporting guideline synthesis without meta-analysis (SWiM) in systematic reviews. A coherent search strategy was designed to retrieve articles in databases such as PubMed, Embase, Scopus, Web of Science, and ClinicalTrials.gov from inception to June 2020. We excluded articles with eligibility criteria of the age of under 50 years old and studies conducted on patients with gestational diabetes. The outcomes were categorized into biomedical, behavioural, and psychosocial outcomes. The methodology of articles was evaluated by the Standard Cochrane Collaboration risk of bias tool in Revman 5.3 software. Findings Overall, 18 studies with 8273 patients with diabetes over the age of 50 were included in this systematic review. Biomedical outcomes such as blood sugar tests and cholesterol tests had significant improvement by using telehealth. Frequency of self-monitored blood glucose (SMBG) and self-efficacy were behavioural outcomes that increased by telehealth utilization. Telehealth had a positive impact on psychosocial outcomes like depression, quality of life (QoL), cognitive decline, and social support. Interpretation Telehealth has the ability to improve multiple outcomes such as behavioural and psychosocial outcomes in health services consumers. Due to varied telehealth interventions and follow-up durations, firm conclusions cannot be reached. As the research investigations studied in the present study were of different kinds and had used different follow-up periods, there is a need for further rigorous studies which consider socio-economic, cultural, and clinical differences.
