Effectiveness of the Stage 4 Smart Insulin Pen DIA:CONN P8 for Glycemic Control in a Real-World Setting

This study evaluated whether a stage 4 smart insulin pen (SIP) provides superior glycemic control compared with a traditional insulin pen (TIP) in individuals with intensively insulin-treated diabetes. Forty-two adults with continuous glucose monitoring (CGM), multiple daily insulin injections, and no prior SIP use were included. After diabetes self-management education (DSME), the SIP group (n=21) initiated SIP, whereas the TIP group (n=21) continued their usual regimens. Glycemic metrics were assessed using CGM before and 2 weeks after DSME. Both groups demonstrated significant improvements in glycemic outcomes. However, SIP users exhibited superior improvements in the percentage of time in range, percentage of time below range (%TBR) <70 mg/dL, %TBR <54 mg/dL, and glycemic risk index compared with TIP users (between-group difference [BD] 11.0%, P=0.046; BD –2.6%, P=0.024; BD –0.9%, P=0.027; BD –18.2, P=0.022, respectively). These findings suggest that SIP, with its bolus calculation and CGM integration, is associated with improved glycemic outcomes in adults with intensively insulin-treated diabetes.
