Collaboratively Designing an App for a More Personalized, Community-Endorsed Continuous Glucose Monitoring Onboarding...

Area of Science:

• Digital Health
• Diabetes Management
• Human-Computer Interaction

Background:

• Acclimating to new technology like continuous glucose monitors (CGM) presents challenges for patients with diabetes (PWD).
• Existing resources may not fully address PWD questions during CGM onboarding.
• There is a need to improve the CGM onboarding process for PWD.

Purpose of the Study:

• To develop a prototype app for facilitating CGM onboarding for PWD using a co-design approach.
• To gather early usability feedback on the developed app prototype.

Main Methods:

• A human-centered design (HCD) approach was employed, including user observation and interviews with PWD and healthcare professionals (HCPs).
• A low-fidelity app prototype was created and refined into a high-fidelity version with features for goal setting, progress tracking, and community support.
• Usability was assessed using the System Usability Scale (SUS).

Main Results:

• Focus group participants found the app prototype usable and acceptable.
• The app achieved a System Usability Scale (SUS) score of 74, exceeding the average score of 68 for tested applications.

Conclusions:

• The prototype app serves as a personalized tool to bridge information and support gaps for PWD new to CGM.
• The app has the potential to enhance ease of use and engagement in diabetes self-management for PWD on an ongoing basis.
