Virtual visits and the use of continuous glucose monitoring for diabetes care in the era of COVID-19.

The coronavirus disease 2019 (COVID-19) pandemic has led to an increase in virtual care utilization for patients with diabetes mellitus (DM). Virtual DM care requires both providers and patients to become familiar with new technology that supports home health monitoring. Continuous glucose monitoring (CGM) is a DM technology that provides 24-hr glucose monitoring and is associated with improved clinical outcomes, including decreased rates of hypoglycemia and lower hemoglobin A1c (A1c). Continuous glucose monitoring use has increased due to ease of use and its ability to allow patients to share data with providers during virtual visits. Although the clinical benefits of CGM use are clear, many providers are overwhelmed by the various options available and large influx of data received. The purpose of this clinical case review is to provide an overview of CGM use in the virtual care setting. Various types of CGMs will be defined and an overview of the patient characteristics shown to benefit most from CGM use will be provided. Further, recommendations for improving clinic workflow when using CGM will be outlined, including strategies to handle the influx of large datasets, outlining the role of the nurse practitioner (NP) and other providers in the clinic, and organizing data for efficient and improved clinical decision making. Continuous glucose monitoring use is hallmarked to revolutionize DM care for many patients, particularly during and after the COVID-19 pandemic. It is important that clinicians understand the nuances of CGM use and organize their virtual clinics to efficiently manage CGM users, leading to improved clinical decisions and patient outcomes.
