The Effect of Telemedicine in Glycemic Control in Adult Patients with Diabetes during the COVID-19 Era-A Systematic Review

Fiorella Sotomayor et al. J Clin Med. .

Abstract

Telemedicine can be an effective tool for managing chronic diseases. The disruption in traditional diabetes care resulting from the COVID-19 pandemic led to global interest in telemedicine. With this manuscript, we evaluated the use of telemedicine for the management of diabetes during the pandemic and its impact on glycemic control, focusing on retrospective and prospective studies which included adult, non-pregnant patients with diabetes. We evaluated whether there was an improvement in HbA1c, time in range (TIR), glucose management indicator (GMI), mean glucose values, hypoglycemic episodes, time below range (TBR), or hospitalizations for hypoglycemia/DKA, depending on the available information provided. This review article highlights the benefits of telemedicine during the global state of emergency, which altered the standard of healthcare delivery. Across the studies reported in this review, telemedicine was shown to be an effective tool for the management of diabetes, illustrating its potential to be the new standard of care. Although these improvements may be confounded by potential extraneous factors present during the pandemic, telemedicine was shown to positively impact glycemic control. Overall, this article highlights the benefits of telemedicine on glycemic control during the global state of emergency, which altered the standard of care. With the rollback of COVID-19 restrictions, and a return to the office, this article emphasizes the necessity to study how telemedicine can be best utilized for diabetes management when compared to the traditional standard of care.
