Effect of structured individualized education on continuous glucose monitoring use in poorly controlled patients with type 1 diabetes: A randomized controlled trial.

<bold>Aim: </bold>We aimed to evaluate the efficacy of structured individualized education combined with real-time continuous glucose monitoring (rt-CGM) on glycemic outcomes in adults with type 1 diabetes.<bold>Methods: </bold>This was a single-center, 3-month, randomized controlled trial of 47 adults with type 1 diabetes with HbA1c ≥ 7.0% (53 mmol/mol). Study participants were assigned randomly (1:1) to a structured education group or control group. The control group received the same education as the intervention group in a 3-month extension study. The primary outcome was the mean difference in time in range (TIR 70-180 mg/dL [3.9-10.0 mmol/L]) between groups.<bold>Results: </bold>TIR was higher for the education group than the control group (63.4% vs. 44.5%), resulting in a between-group difference of 15.3% (95% CI 7.9 to 22.8, p < 0.001) at week 12. HbA1c decreased 0.5% (5.5 mmol/mol) more in the intervention group than the control group at week 12 (-0.1 to -1.0, p < 0.001). In the extension period, TIR increased significantly (8.9% [2.2 to 15.6], p = 0.01) in educated control group.<bold>Conclusions: </bold>In adults with type 1 diabetes, rt-CGM use with individualized education resulted in better TIR than rt-CGM alone, highlighting the importance of personalized structured education when using rt-CGM.
