Experiences of Using Wearable Continuous Glucose Monitors in Adults With Diabetes: A Qualitative Descriptive Study

Abstract

Purpose: The purpose of the study was to understand the experiences of adults with diabetes wearing a continuous glucose monitor (CGM). Methods: This qualitative, descriptive study included 19 adults with type 1 diabetes or type 2 diabetes, who had used the FreeStyle Libre CGM for at least 4 weeks, from an outpatient clinic at a university-affiliated hospital in Korea. Data were collected through in-depth interviews and analyzed using an inductive content analysis approach. Results: The content analysis revealed 3 major themes—navigating glucose level fluctuations, reframing diabetes self-care and improving quality of life, and device improvement and service quality. Participants reported that CGMs offered convenient glucose level monitoring, allowed early response to rapid glucose changes, and facilitated effective patient-clinician communication. Participants expressed concerns about the financial burden and limited services, recommending improvements for devices, consumer services, and health insurance coverage. Conclusions: Study findings indicated that using wearable CGMs could improve self-care and quality of life in adults with diabetes. Using CGMs could improve patients’ understanding of how diabetes self-care management affects real-time glucose levels. Health care providers could support patients’ self-care by using device data. Improvements in quality, services, and insurance coverage could increase user satisfaction and promote self-care.
