NCT04158921

Brief Summary

This is a single arm open label pilot clinical trial that will assess patient-reported blood glucose levels before and after using the Control:Diabetes mobile app, while collecting user feedback and recommendations for further improvements to the app functionality and user interface. This study will enroll approximately 70 individuals with insulin-treated diabetes mellitus. The study will include two online surveys (baseline and exit), one study initiation phone call, and will also collect data entered by the users into the mobile app.

Outcome Measures

Primary Outcomes (1)

  • The mean change in blood glucose.

    As recorded by the patient in the app.

    Measured between the first two weeks and the last two weeks of the study.

Secondary Outcomes (1)

  • The change in the number of hypoglycemic episodes.

    Measured every week between the two weeks prior to the study entry and the last two weeks of study follow-up.

Study Arms (1)

The Control:Diabetes mobile app for Diabetes self-management.

Other: Control:Diabetes mobile app

Interventions

The Control:Diabetes app will encourage patients to: a) predict their blood glucose level at a particular time point in the future (e.g. the next morning); then b) enter their actual blood glucose levels when that time (the next morning) comes; and c) enter reasons for the discrepancy between prediction and reality, if the prediction was significantly (e.g. \> 20%) different from the actual measurement. We hypothesize that by repeatedly encouraging disassembly of blood glucose changes into individual reasons (cognitive task analysis) while providing an incentive in the form of being able to more accurately predict blood glucose levels (operant conditioning), the app will prompt the patient to learn how various internal and environmental factors affect their blood glucose. They will then be able to adjust their behavior and medications to improve their blood glucose control.
