Efficacy and Safety of Continuous Glucose Monitoring and Intermittently Scanned Continuous Glucose Monitoring in Patients With Type 2 Diabetes: A Systematic Review and Meta-analysis of Interventional Evidence
Traditional diabetes self-monitoring of blood glucose (SMBG) involves inconvenient finger pricks. Continuous glucose monitoring (CGM) and intermittently scanned CGM (isCGM) systems offer CGM, enhancing type 2 diabetes (T2D) management with convenient, comprehensive data. This study aims to assess the benefits and potential harms of CGM and isCGM compared with usual care or SMBG in individuals with T2D.The researchers conducted a comprehensive search of MEDLINE, Embase, the Cochrane Library, Web of Science, and bibliographies up to August 2023. They included 26 RCTs (17 CGM and 9 isCGM) involving 2,783 patients with T2D. CGM reduced HbA1c and glycemic medication effect score, reduced user satisfaction, and increased the risk of adverse events. isCGM reduced HbA1c by ?0.31%, increased user satisfaction, improved CGM metrics, and increased the risk of adverse events. Accordingly, both CGM and isCGM demonstrated a reduction in HbA1c levels in individuals with T2D, and unlike CGM, isCGM use was associated with improved user satisfaction. The impact of these devices on body composition, blood pressure, and lipid levels remains unclear, while both CGM and isCGM use were associated with increased risk of adverse events.
