Background The evaluation of user satisfaction with an automated insulin delivery (AID) system is crucial. The aim was to assess the change in user satisfaction after upgrading from a previous to a next generation sensor integrated in the same AID system. Methods A prospective intervention study was conducted. Type 1 diabetes subjects simultaneously upgraded from Guardian-Sensor®4 to Simplera-Sync TM , integrated in the MiniMed TM -780G system. User satisfaction was evaluated at baseline and after 3 months of use of Simplera-Sync TM by the Glucose Monitoring Experience Questionnaire (GME-Q), a validated questionnaire designed to evaluate the experience with a glucose monitoring system. Glucose control and use of the system were also compared. Results Ninety-one subjects were included (age: 38 ± 15 years-old, 59% female). GME-Q global score increased from 3.84 ± 0.49 to 4.40 ± 0.46. All subscales, effectiveness, convenience, and intrusiveness also improved. Sensor use increased from 93% 91, 95 to 98% 96, 99 and time in automode from 94% 92, 97 to 100% 97, 100, with 50% of the subjects achieving 100% of time in automode. A reduction in time in moderate hypoglycaemia and the number of hypoglycaemia episodes was observed. Conclusion Upgrading to a new sensor, as part of an AID system, can improve user satisfaction and allow for increased sensor use and time in automation.
