What You Need to Know Before You Apply

What is the purpose of this trial?

The trial aims to help Black/African American children and young adults with type 1 diabetes use advanced diabetes technology more easily. It will test whether a smartphone app, called Glucosano, paired with support from a community health worker (diabetes technology coach), makes devices like continuous glucose monitors and insulin pumps more accessible and acceptable. Participants will either continue their usual care or receive additional support through the app and coaching. Suitable candidates for this trial identify as Non-Hispanic Black, have type 1 diabetes, and are not currently using an automated insulin delivery system. As an unphased trial, this study offers a unique opportunity to contribute to research that could enhance access to diabetes technology for the community.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications. However, you must not have used an automated insulin delivery system in the past 3 months.

What prior data suggests that the Glucosano app and community health worker coaching are safe for Black/African American patients with type 1 diabetes?

Research shows that people generally like and easily use digital health tools like the Glucosano app. A report on managing diabetes highlights that smartphone apps can help individuals with diabetes take better care of themselves and improve their health. No major safety issues have been reported with these apps.

Additionally, community health workers play a crucial role in assisting people with diabetes. Studies indicate they help young people use diabetes devices more effectively. Again, no major safety issues have emerged with this approach.

Overall, both the app and coaching methods in this study appear safe based on existing research. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about the Glucosano App + Coaching for Type 1 Diabetes because it offers a more integrated approach to managing the condition. Unlike traditional treatments that primarily focus on insulin management, this method combines a smartphone app with a community health worker who acts as a diabetes technology coach. This approach provides continuous remote monitoring and personalized support, which can lead to better glucose control and empower patients to take a more active role in their own care. By linking diabetes devices to a real-time dashboard, it aims to offer better insights into daily health patterns, potentially improving overall diabetes management.

What evidence suggests that the Glucosano app and coaching could be effective for type 1 diabetes?

Research has shown that self-management smartphone apps, like Glucosano, can help people with type 1 diabetes manage their blood sugar levels. These apps serve as useful additions to regular diabetes care. However, some studies have found that they do not significantly lower HbA1c levels (a measure of average blood sugar over time) when used with standard care. In this trial, participants in one arm will use the Glucosano app alongside coaching from community health workers.

Previous studies have shown promise for coaching from community health workers. Specifically, it has been linked to a reduction in HbA1c by at least 1.0% for many participants, suggesting it can help improve blood sugar control. Community health workers can also help reduce disparities in the use of diabetes technology among different racial groups. ^{3 6 7 8 9}

I have type 1 diabetes and need insulin.

Exclusion Criteria

Non-English speaking guardians

I have been diagnosed with Type 2 or a specific genetic form of diabetes.

You have used an automated insulin delivery system in the last 3 months.

Published Research Related to This Trial

A total of 1019 Android and 1303 iOS apps were identified as relevant for diabetes self-management, but none met all criteria for providing comprehensive and accredited information, highlighting a gap in quality and reliability.

Most diabetes self-management apps are available in Chinese and English, which account for over 80% of the total apps, suggesting a need for more diverse language options and tailored functionalities to better serve users in different regions.

The Diabesdagboga smartphone app and Diani web portal allow for comprehensive tracking of diabetes-related data, including blood sugar levels, carbohydrate intake, insulin doses, and physical activity, enhancing patient engagement and data analysis.

A case report of a patient using this system for nearly two years showed a significant improvement in metabolic control, with an 18.6 mmol/mol decrease in HbA1c, indicating better long-term blood sugar management.

A study involving 31 diabetes educators in Australia revealed that they found the use of technology in managing type 1 diabetes to be burdensome, indicating a need for better support and training in technology use.

Despite the potential benefits of diabetes-related technologies, care delivery was often fragmented and inconsistent, suggesting that improvements in policy and service structure are necessary to enhance the effectiveness of these tools in patient care.

In a study of 81 youths with type 1 diabetes, using a glucometer-connected mobile app increased the frequency of self-monitoring blood glucose (SMBG) by 2.3 times with each additional data sync, indicating improved engagement in diabetes self-management.

However, the frequency of syncing glucometer data did not show a significant impact on hemoglobin A1c (HbA1c) levels or mean blood glucose, suggesting that while the app may enhance monitoring habits, its effect on overall glycemic control is still uncertain.

Diabetes-related apps combined with virtual coaching can significantly improve glycemic control and promote meaningful behavior changes compared to using apps alone, addressing common treatment barriers effectively.

Users of these enhanced apps report high satisfaction and prolonged engagement, suggesting that virtual coaching may be a valuable tool in diabetes education, although further research is needed to explore its long-term effects across diverse populations.

The Sugar Sleuth mobile app, used alongside the FreeStyle Libre™ glucose sensor, led to a significant average reduction in A1c levels by 0.5% over 14 weeks in adults with type 1 diabetes, indicating improved glycemic control.

Participants also reported a decrease in daily carbohydrate intake by an average of 43 grams, suggesting that the app effectively supported dietary management, although no significant changes were observed in other glycemic metrics or insulin dosage.

The #WeAreNotWaiting movement has led to the development of do-it-yourself artificial pancreas systems (DIYAPS) by motivated individuals in the diabetes community, which integrate continuous glucose monitoring and insulin pumps to improve glycemic control and quality of life for people with type 1 diabetes.

While DIYAPS show promising improvements in diabetes management based on anecdotal evidence and observational studies, their unregulated nature raises safety concerns, and there are significant barriers to acceptance among healthcare professionals and regulatory bodies due to ethical, legal, and funding issues.
