Insights
Continuous Glucose Monitoring (CGM) systems can improve diabetes management. A revised leaflet helps people with type 1 diabetes personalize CGM use for better glucose control and understanding.
Area of Science:
- Diabetes management
- Endocrinology
- Medical informatics
Background:
- Continuous Glucose Monitoring (CGM) systems are increasingly used by people with diabetes, particularly type 1 diabetes (T1D).
- Despite CGM use, many individuals with T1D do not meet American Diabetes Association HbA1c targets.
- There is a need for tools to enhance personalized understanding and utilization of CGM data.
Purpose of the Study:
- To develop and refine a practical tool for people with diabetes to improve their personalized understanding of CGM.
- To enhance self-management strategies for individuals using CGM.
Main Methods:
- A leaflet titled "Guidelines to Improve Glucose Control Using CGM" was created.
- Semistructured interviews were conducted with 12 adults with T1D to gather feedback on the leaflet's relevance, readability, and usability.
- Thematic analysis of interview data informed revisions to the leaflet content.
Main Results:
- Participants highlighted specific information and advice needs related to CGM use.
- The data emphasized the importance of personalizing CGM strategies for individual diabetes management.
- Feedback focused on making the information actionable for self-management.
Conclusions:
- Effective use of CGM systems is linked to improved medical and psychosocial outcomes.
- Understanding user expectations, matching skills, and tailoring CGM use to individual needs are crucial for consistent benefits.
- Personalized approaches are essential for maximizing the advantages of CGM for people with diabetes (PWD).
Background:
Increasing numbers of people with diabetes, especially those with type 1 diabetes (T1D), are using continuous glucose monitoring (CGM) systems to support their diabetes self-management, yet even so only approximately 30% of individuals with T1D meet the American Diabetes Association HbA1c target of 58 mmol/mol (7.5%) for children and 53 mmol/mol (7.0%) for adults. We aimed to produce a useful tool for people with diabetes to improve personalized understanding of CGM.
Method:
A brief leaflet titled "Guidelines to Improve Glucose Control Using CGM" was developed for people with diabetes. Semistructured interviews were held with 12 adults with T1D, focusing on their views regarding the relevance, readability, and usability of the newly revised leaflet. Participants were specifically asked to share what they would find most useful in terms of information and advice provided as well as how to make use of that in the context of their own diabetes self-management. Data were analyzed thematically and used to inform revisions of the leaflet content.
Results:
Data highlighted information and advice needs as well as personalization in terms of own diabetes management.
Conclusions:
CGM systems are associated with improved medical and psychosocial outcomes, especially when used effectively to meet the individual needs of the user. Ensuring greater understanding of the individual's expectations when first starting CGM, matching experience and skills to meet those expectations, and tailoring use to the individual needs of each person with diabetes (PWD) are all required to achieve widespread and consistent benefit.
