1160-OR: Empowerment through Visibility: Lived Experiences with CGM vs. Routine Care in Adults with Type 2 Diabetes Not on Insulin

Key Points

This study investigates the effects of continuous glucose monitoring (CGM) on self-management for adults with type 2 diabetes not treated with insulin.
Qualitative design using semi-structured virtual interviews with participants from the CONNECT randomized trial at month 6.
Included 30 adults (15 using CGM, 15 in routine care) with varying ages and genders.
Transcripts were analyzed using content and thematic analyses, ensuring rigor with multiple coders.
CGM provided actionable data, enhancing decision-making confidence compared to routine care's uncertainty.
Behavioral changes were more consistent with CGM due to personalized feedback, while routine care lacked tailored guidance.
The psychological benefits of CGM included reduced cognitive burden and increased feelings of control and hope.

Abstract

Introduction and Objective: Adults with T2D not treated with insulin face distinct and ongoing self-management challenges. This qualitative study explored how CGM versus routine care (RC, without CGM) impacts psychological, behavioral, and emotional outcomes in this population. Methods: Semi-structured interviews were conducted virtually with a randomly selected subset of participants from the CONNECT randomized trial at month 6 of the 12-month study. By this time, participants in the CGM arm had been using real-time CGM for six months, while RC participants had continued without CGM. Interviews were recorded, transcribed verbatim, and analyzed using content and thematic analyses. Multiple coders independently reviewed the transcripts to ensure analytical rigor and validity. Results: Thirty adults participated in interviews (CGM: n=15, mean age=65 SD=7, 60% male; RC: n=15, mean age=54 SD=14, 60% male). Three primary themes emerged: 1) Real-time, actionable feedback: CGM supported more confident, data-driven decisions, while RC involved guesswork and difficulty linking actions to outcomes; 2) Behavioral and 3) Psychological Current; Dexcom, Inc.
