Study to Test Efficacy of Real-time Reminders on Apple Watch To Decrease Late or Missed Meal Boluses

18 april 2020 uppdaterad av: Marc Breton, University of Virginia

Pilot Study to Test Efficacy of Real-time Reminders on Apple Watch To Decrease Late or Missed Meal Boluses

This will be a randomized, cross-over, unblinded study with subjects randomized upon entry into the study to either begin using the Klue software for 6 weeks or to continue with their usual care for 6 weeks. Subjects are eligible for enrollment if they are using a continuous glucose monitor (CGM) with an insulin pump or an insulin pen with memory, and are missing or late in giving at least 4 food boluses in the previous two weeks. Missing or late meal boluses will be assessed through their pump/pen and sensor downloads. This is a pilot study. There is no preliminary data to do a true power calculation. The primary outcome will be the change in the number of missed meal boluses in the two weeks prior to each visit. Secondary outcome measures will be the number of missed meal boluses in each month of the study, change in HbA1c levels (measured every 6 weeks), accuracy of the Klue software in detecting meals (true positive and false positive rates), and a user satisfaction survey.

Intervention / Behandling
Experimentell: Klue App Use then Usual Care
Subjects will use the Klue App during the first 6 weeks of the trial. At 6 weeks, subjects will discontinue Klue App use and will continue the final 6 weeks without the product.
The Klue App utilizes an Apple Watch to detect eating or drinking behavior. The App can initiate a sequence of questions when eating/drinking is detected to determine if a subject has administered a bolus for the meal or if they need to do so.
Experimentell: Usual Care then Klue App Use
Subjects will begin the study without using the Klue App during the first 6 weeks of the trial. At 6 weeks, subjects will begin the use of the Klue App and will continue the final 6 weeks with the product.
The Klue App utilizes an Apple Watch to detect eating or drinking behavior. The App can initiate a sequence of questions when eating/drinking is detected to determine if a subject has administered a bolus for the meal or if they need to do so.
