Abstract
OBJECTIVE: Automated insulin delivery (AID) systems show great promise for improving glycemic outcomes and reducing disease burden for youth with type 1 diabetes (T1D). The current study examined youth and parent perspectives after using the insulin-only iLet Bionic Pancreas (BP) during the 13-week pivotal trial. METHODS: Parents and youth participated in focus group interviews, with questions assessing participants' experiences in a variety of settings and were grounded in the Unified Theory of Acceptance and Use of Technology. Qualitative analysis was completed by 3 authors using a hybrid thematic analysis approach. RESULTS: Qualitative analysis of focus groups revealed a total of 19 sub-themes falling into 5 major themes (Diabetes Burden, Freedom and Flexibility, Daily Routine, Managing Glucose Levels, and User Experience). Participants' overall experience was positive, with decreased burden and improved freedom and flexibility. Some participants reported challenges in learning to trust the system, adjusting to the user interface, and the system learning their body. CONCLUSION: This study adds to the growing literature on patient perspectives on using AID systems and was among the first to assess caregiver and youth experiences with the BP system over an extended period (13 weeks). Patient feedback on physical experiences with the device and experiences trusting the device to manage glucose should inform future development of technologies as well as approaches to education for patients and their families.
