Telehealth Interventions to Improve Diabetes Management Among Black and Hispanic Patients: a Systematic Review and Meta-Analysis

Abstract

Background Previous systematic reviews have found that telehealth is an effective strategy for implementing interventions to improve glycemic control and other clinical outcomes for diabetes patients. However, these reviews have not meaningfully focused on Black and Hispanic patients—partly because of the lack of adequate representation of people from racial and ethnic minority groups in clinical trials. It is unclear whether telehealth interventions are effective at improving glycemic control among Black and Hispanic patients given the disproportionate number of barriers they face accessing health care. Objectives A systematic review and meta-analysis of randomized control trials that used telehealth interventions for improving glycemic control among Black and Hispanic diabetes patients. Methods We reviewed PubMed, Embase, Web of Science, CINAHL, PsycINFO, and clinicalTrials.gov from inception to March 2021. We used a narrative summary approach to describe key study characteristics and graded the quality of studies using two reviewers. The pooled net change in HbA1c values was estimated across studies using a random-effects model. Results We identified 10 studies that met our inclusion and exclusion criteria. Nine studies were included in the meta-analysis. Only one study was rated as having low bias. Telehealth interventions were primarily delivered by telephone calls, text messages, web-based portals, and virtual visits. Most interventions involved delivering diabetes self-management education. Telehealth intervention pooled across studies with a mix of Black and Hispanic participants (> 50% sample) was associated with a − 0.465 ([CI: − 0.648 to − 0.282], p = 0.000) reduction in HbA1c. Conclusions Our findings suggest telehealth interventions are effective at improving glycemic control among Black and Hispanic diabetes patients.

Younger Women’s Experiences of Stroke: A Qualitative Study

“…It has also been suggested that a combination of selfmanagement and telehealth could offer promising interventions (Saragih et al, 2021). Telehealth applications can be particularly helpful for messaging, telephone, video conferencing, and online platforms and these are very applicable for patients at home otherwise limited by time and distance (Anderson et al, 2022;Hwang et al, 2021).…”

Factors Associated With Receipt of Diabetes Self-Management Education and Support for Type 2 Diabetes: Potential for a Population Health Management Approach

“…12,13 With the recent shift toward telehealth during the COVID-19 pandemic, there is potential for more patients to overcome these barriers and benefit from participation in DSMES delivered virtually, a modality that has been shown to be effective. [14][15][16] Despite the potential for improved virtual access, systems-based factors like low referral rates by providers, inadequate numbers of diabetes care and education specialists (DCES), and poor reimbursement present additional challenges to optimal DSMES uptake. 11,17,18 The population of adults with T2D in the United States is projected to triple to more than 60 million by 2060, and all patients cannot be served by the limited number of active DCES.…”

Telemedicine for the management of diabetic patients in a high-complexity Latin American hospital

“…Telemedicine or telehealth uses telecommunications to support different areas of health care, becoming a fundamental tool to reduce barriers to health access, with a high level of satisfaction for patients and health personnel [10]. Despite the limitation of telemedicine for physical examination, it can be a useful tool for the management and follow-up of patients with diabetes; it can even improve the glycemic control of these patients [11][12][13]. In the present study, we describe the changes in glycosylated hemoglobin (HbA1c) in patients with type 1 and type 2 diabetes patients seen by teleconsultation.…”
