Preference was given to randomized controlled trials, real-world observational studies, and meta-analyses. Guidelines, consensus statements, and systematic reviews were also considered. An overall favourable trend was seen for people living with T2DM who used CGM in addition to their regular therapies. When compared with traditional self-monitoring of blood glucose, CGM was found to improve glycemic outcomes as evidenced by significant differences in change from baseline for glycated hemoglobin, time in range, time above range, time below range, and glycemic variability. Patient satisfaction reflected favoured use of CGM, with an overall cost-efficiency improvement as well. The Canadian health care system could benefit from CGM use through decreased hospitalizations and related costs. Integration of CGM to enhance treatment for Canadians living with T2DM as a component of comprehensive care should be recognized.
