MDD31 - Towards Accessible Glucose Monitoring: Usability Insights From the GlucoCheck App for Seniors
SessionPoster Session 1
DescriptionThe United States is facing a public health crisis due to the increasing prevalence of diabetes and related metabolic conditions. With over 12% of Americans living with diabetes, 30% of adults over 65 diagnosed with the condition, and nearly 10% of pregnant women affected by gestational diabetes, managing blood glucose levels is critical for these populations. Moreover, 47% of people over age 60 are diagnosed with metabolic syndrome, a condition that raises the risk of diabetes, heart disease, and stroke. Blood glucose (BG) monitoring, a cornerstone of diabetes management, traditionally involves invasive, inconvenient methods like finger-prick tests and implantable devices, which pose risks of infection, particularly among older adults with compromised skin and immune systems. To address these challenges, GlucoCheck, a non-invasive, wearable glucose monitoring device, offers an innovative alternative. Utilizing near-infrared spectroscopy and AI-driven algorithms, GlucoCheck provides an accurate, non-invasive method to monitor blood glucose levels across diverse skin tones. The GlucoCheck Companion Mobile App allows users to view, track, and share their glucose data seamlessly.
The objective of this study was to evaluate the usability of the GlucoCheck companion app, focusing on its importance for improving patient outcomes and enhancing diabetes management. The goal of GlucoCheck is to revolutionize blood glucose monitoring by providing a non-invasive, user-friendly solution for patients with diabetes and/or seniors with metabolic syndrome. The companion app is an integral part of this solution, offering real-time data tracking, historical trends, and a user interface designed to support decision-making in collaboration with healthcare providers. Usability studies play a crucial role in ensuring that the GlucoCheck App meets the needs of its diverse user base, which includes older adults who may have limited experience with mobile apps. The app's design must prioritize ease of use, clarity, and accessibility, especially for users with reduced technical proficiency or vision issues. Ensuring HIPAA compliance and data security is another critical consideration, as the app facilitates the sharing of sensitive medical information.
The usability study focused on the following aspects such as demographics, experience with mobile apps, and core functionalities of the app asking participants to complete some tasks in the app, for instance checking glucose values in real-time, viewing average glucose values over time, sharing data with healthcare providers, or adding food information. Quantitative and qualitative analyses were performed to evaluate the overall usability, effectiveness, and user satisfaction of the GlucoCheck companion app. The quantitative analysis focused on task performance metrics, such as the ease of completing specific functions (e.g., checking glucose levels, adding food information), while the qualitative analysis gathered user feedback on design elements, navigation, readability, and areas of confusion. These combined analyses provided comprehensive insights into how well the app supports diabetes management for diverse users, particularly older adults with varying levels of mobile app experience.
The study revealed generally positive feedback with high satisfaction ratings for key tasks indicating ease of use for checking glucose values and adding food information. Lower scores were given to tasks such as logging in with Facebook or viewing average glucose values, suggesting areas for improvement, particularly in terms of user interface design. Qualitative insights provided additional context for user feedback in different aspects: 1) Design and Readability: Older users appreciated the visual design, particularly the use of color and clear data visualization. However, some reported difficulties with font size and icon clarity, emphasizing the need for further adjustments to improve readability for seniors. 2) Navigation: While the app was generally intuitive, some users struggled with more advanced features like adding meals manually, highlighting a need for simplified instructions or better guidance. 3) Data Privacy Concerns: A few participants expressed concerns about potential privacy issues, particularly with the Facebook login option. Ensuring users are fully informed about privacy protocols and offering secure, alternative login methods is essential.
The results of the usability study underline the importance of creating a mobile application that is easy to navigate, accessible, and tailored to the needs of older adults and people with diabetes. Specifically, the app’s strengths lie in its real-time monitoring and seamless integration with the wearable GlucoCheck device, providing patients with critical data that can help them make informed decisions in managing their condition. The feedback also revealed opportunities for improvement, such as enhancing font size, clarifying iconography, and refining the flow for tasks that require multiple steps, like adding food information. Incorporating user suggestions and optimizing the app based on this feedback will help to improve patient engagement and overall satisfaction.
Ultimately, the GlucoCheck Companion App, in conjunction with its innovative wearable device, has the potential to transform how individuals manage diabetes and related conditions. By focusing on user experience and continuously improving based on feedback, GlucoCheck can offer a solution that not only improves health outcomes but also makes life easier for those who rely on glucose monitoring every day. The next steps include refining the app’s usability through further testing, particularly with a more diverse user base, and improving features that allow seamless communication with healthcare providers. The goal is to ensure that GlucoCheck remains an inclusive, accessible, and effective tool for diabetes management.
