Real-world Effects of Using Intermittently Scanned Continuous Glucose Monitoring and Pharmacist-led Coaching on the Management of Type 2 Diabetes Among Adults Not Using Insulin (REAL isCGM T2D)

Summary

The goal of this prospective study is to evaluate diabetes outcomes after initiating second generation intermittently scanned continuous glucose monitoring (isCGM) plus one pharmacist consultation session compared with capillary blood glucose (CBG) monitoring among insulin-naïve adults with type 2 diabetes (T2D) in a specialist endocrinology clinical setting in Canada. Primary Outcome - To evaluate change in HbA1c at 3-6 months follow-up after initiating isCGM plus one pharmacist consultation (isCGM cohort) compared with CBG monitoring (CBG cohort) among insulin-naïve adults with T2D. Secondary Outcomes - To determine the change in metabolic outcomes and patient reported outcomes (PROs) and number of non-insulin antihyperglycemic agents (AHAs) prescribed from baseline to 3-6 months (± 6 weeks) in the isCGM cohort compared to the CBG cohort. Another secondary outcome is to assess isCGM metrics and number of isCGM discontinuations in the isCGM cohort at 3-6 months (± 6 weeks) compared to baseline. Additionally the study will describe and/or evaluate glycemic and metabolic outcomes, and PROs in participants who initiate an isCGM device and opt to enroll in a diabetes coaching program (isCGM+coaching cohort) at baseline compared to follow-up at 3-6 months (± 6 weeks). Exploratory Outcomes - To compare change in HbA1c between the matched isCGM cohort and CBG cohort by subgroups: age (\< 65 years old vs ≥ 65 years old) and baseline HbA1c (\< 8.5% vs ≥ 8.5%).
