Abstract
Objectives
To understand the long-term behavior changes associated with use of the FreeStyle Libre 2 sensor-based glucose monitor by people living with type 2 diabetes (T2D).Methods
This was a qualitative study of adults with T2D living in Quebec and using FreeStyle Libre 2. Discussions were moderated by an experienced facilitator using a semi-directed discussion guide. Discussions were transcribed and analyzed thematically.Results
16 people living with T2D who had been using FreeStyle Libre 2 for > 6 months participated in two focus groups (non-insulin treatments, six women and three men; basal insulin, two women and five men). There were no material differences in responses or anecdotes between the two groups. Use of FreeStyle Libre 2 was associated with four main themes: 1) Personalized knowledge, including participants' sense of autonomy and control and their ability to see the effect of their actions on glucose levels and to make informed choices, such as modifying their diet; 2) Improved communication with healthcare providers (HCPs), who can access patients' glucose data in real-time if shared via the smartphone app; 3) Reductions in hypoglycemia, particularly due to warnings of low glucose levels; and 4) Long-term benefits, including reductions in stress and improved HRQoL.Conclusion
Long-term users found that FreeStyle Libre 2 improved their diabetes self-management, communication with healthcare providers, HRQoL, and stress levels, and facilitated lifestyle changes. Individuals with T2D described the device empowering ongoing healthy behavior change. This research serves as a person-centered qualitative finding to consider in access decisions.
