Continuous Glucose Monitoring: Updated 2023

Introduction Diabetes is a chronic and complicated disease in which glycemic management must be accompanied by lifestyle modifications to improve clinical outcomes and quality of life. Technology-enabled health care has been among the top 3 types of quality improvement interventions found to be effective in improving diabetes care. (Rodriguez et al 2022) Advantages of this technology is not limited to increased efficiency, cost saving, or overall patient satisfaction. (Isaacs et al 2020) Continuous glucose monitoring (CGM) has been at the forefront of this technology because of its broad application across different settings. CGM is particularly beneficial for persons with diabetes (PWD) with variable glycemic management because the data from CGM highlights areas that need treatment intervention. By preventing hypoglycemia, improving glycemic control, and increasing overall time in range (TIR), CGM is an effective tool for PWD to actively manage their diabetes. Both professional- and personal-use CGM (whether intermittently scanned or real-time CGM) provides patient-centered data that clinicians and PWD can use to make actionable treatment decisions. (Miller 2020) Clinical guidelines stress the importance of proper education, support, and follow-up when using CGM technology. Utilization of CGM without these factors in place can be overwhelming as well as a barrier to optimal patient care. (ElSayed et al 7. 2023)
