Glycaemic control after connected insulin pen initiation in people living with diabetes: Results from a real‐world setting
Authors' conclusion
These real-world data show that glycaemic outcomes improved after connected insulin pen initiation, especially in individuals with the highest unmet need (i.e., lowest baseline TIR). Combining a connected insulin pen with additional support, such as app-based training or education, may further improve glycaemic control.
Study context
- Population
- Adults (≥18 years) with insulin-treated diabetes using continuous glucose monitoring (CGM) who started bolus insulin via a connected insulin pen; mean (SD) age 43.7 (15.7) years
- Participants
- 86,133 adults
- Exposure
- Glycaemic control after vs before connected insulin pen initiation for bolus insulin
- Outcome
- Key glycaemic outcomes: TIR (3.9-10.0 mmol/L), TAR (>10.0 mmol/L), TBR (<3.9 and <3.0 mmol/L)
