The Experience of Patients with Type 1 Diabetes Mellitus with the Use of Glucose Monitoring Systems: A Qualitative Study.

Aim: The purpose of this study was to explore the broad experience of continuous glucose monitoring from the perspective of patients diagnosed with type 1 diabetes mellitus, including not only their emotions and feelings but also the lifestyle changes, perceptions, and social aspects associated with its use.

Design

This is a phenomenological qualitative study. Patient or Public Contribution: The sample consisted of 10 adult patients diagnosed with type 1 diabetes who had been using the continuous glucose monitoring system for at least 6 months and were patients of the Endocrinology and Nutrition Service of the University Hospital Complex of Ourense.

Methods

The recorded interviews were conducted in November 2024. The conversations were audio-recorded with the participants' consent, and then transcribed for thematic analysis.

Results

Three main categories were identified: "experience prior to continuous glucose monitoring" (accessibility, prior knowledge, and expectations), "experience with the use of continuous glucose monitoring" (perception of healthcare support, concerns, strengths, and alarm management), and "experience regarding the disease" (self-management of the disease and safety). Despite the fact that diabetes mellitus is a complex chronic disease, all participants provided a positive assessment of their progress and improved control through continuous glucose monitoring.

Conclusions

All participants felt more secure and protected with continuous glucose monitoring, improving their quality of life. The main concern among the subjects was the possibility of the sensor failing. They positively valued the alarm system in case of hypoglycemia. The CGM is a highly effective tool for the management and self-control of diabetes and promotes the relationship between patients and professional health. Impact: The findings of this study have important implications for clinical care, highlighting the need for more training and more health education at the first level of health care, such as health centers.
