Why carry out this study?

Optimizing glycemic control is challenging for many pediatric patients with type 1 diabetes (T1D); combining data from smart insulin pens and continuous glucose monitoring (CGM) could mitigate some of these obstacles.

This one-arm, prospective, real-world observational study investigated the effects of introducing a smart pen on glycemic control in pediatric patients with T1D who were already using CGM.

Outcomes were compared between baseline and follow-up (≥ 12 months) and included hypoglycemic events (events over 24 h and nocturnal events), time above range, time below range (TBR), and time in range.

What was learned from the study?

This real-world study demonstrated that introducing the smart insulin pen could have a positive impact on glycemic control in pediatric patients with T1D by reducing the number of hypoglycemic events (total over 24 h and nocturnal events) and decreasing the proportion of TBR level 2.

Larger controlled studies stratified by age may be required to confirm the results of this investigation.
