Real-world outcomes using the Tandem Mobi insulin pump with Control-IQ+ technology and Dexcom G7

Real-world performance of the Tandem Mobi insulin pump with Control-IQ+ technology has been evaluated in small early access studies, but data from larger populations with long-term use has yet to be presented, especially with the use of newer sensors and newly indicated populations.

The Tandem Mobi insulin pump with Control-IQ+ technology paired with the Dexcom G7 continuous glucose monitor (CGM) was evaluated in 29,265 users of the combined system, for a median of 5.1 months of use per user. Users had to have at least 30 days of use of the combined system in the Tandem Source web application to be included in the analysis. Customer service check-in surveys that were performed as part of routine postmarket surveillance activities were also analyzed.

CGM availability exceeded 95% for all age groups, with an overall median 97.8%. Median time in closed loop was 94.1%, demonstrating strong reliability of the CGM connection in real-world settings. Median time in range 3.9-10.0 mmol/L was 70.8% for adults, 62.3% for children age 6-17 years old and 59.5% for children 2-5 years old. Time <3.9 mmol/L was low at 1.4%. Postmarket surveillance surveys completed by 1941 of these users reported high satisfaction with pump usability, CGM connectivity and the automated insulin delivery algorithm.

These findings demonstrate safe and effective use of the Tandem Mobi insulin pump with Control-IQ+ technology paired with the Dexcom G7 sensor in the at-home, unsupervised setting.
