A Systematic Review on the Impact of Electronic Consultations on Diabetes Care.

Objectives: Primary care physicians (PCPs) are increasingly challenged with managing glycemic control in people with diabetes (PWD), especially in the setting of a shortage in endocrinologists. Electronic consultations (e-consults), which enable asynchronous communication between PCPs and specialists through electronic health records, have been introduced to address these issues. This systematic review aims to evaluate the impact of e-consults on glycemic control in PWD, focusing on changes in HbA1c levels.

Methods: Two independent reviewers searched PubMed, EMBASE, and the Cochrane Library, following Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 guidelines. The review encompasses randomized controlled trials and observational studies. Two reviewers extracted data pertaining to prespecified outcomes of each interest from each included study.

Results: Summary tables and narrative synthesis were used (PROSPERO 2024 CRD42024503278). Six studies were included, -two randomized controlled trials and 4 observational studies-assessing the role of e-consults in diabetes care. Most studies did not report significant differences in HbA1c levels between e-consult and control groups. However, benefits such as improved medication usage, reduced costs, enhanced access to specialist care, shorter wait times for in-person visits, and better educational opportunities for PCPs were noted. Implementation barriers included PCP familiarity with e-consults and patient adherence. Limitations include inclusion of only 2 trials and 4 observational studies and heterogeneity between them.

Conclusions: E-consults provide valuable benefits in managing diabetes, particularly in resource-limited settings. E-consults offer a promising solution to the endocrinologist shortage, though further research is needed to identify which PWD would benefit most.
