Abstract
Background and Aims
To assess CGM use among older adults with T1D we analyzed data from the Wireless Innovation for Seniors with Diabetes Mellitus (WISDM) study, a 6-month multi-center randomized trial of CGM with a 6 month observational extension study.
Methods
The cohort included the 103 adults ≥60 years old with T1D randomized to use Dexcom G5 CGM for up to 12 months (median age 68 years, median T1D duration 39 years, 59% female, 92% non-Hispanic white, 56% insulin pump use, mean HbA1c 7.6%). Device data were downloaded to assess CGM use and participants reported use of device features.
Results
CGM use remained high throughout the study with 92% still using CGM at 12 months and 82% using CGM 6 or more days per week (Table). At 12 months, among those still using the device, 37% reported using the smartphone application to view glucose values. Only 12% chose to share their data with another person via the smartphone application (31% of app users). 51% reported reviewing retrospective CGM data at least 1 time per month, up from 33% at 4 weeks. At 4 weeks, 69% were using the CGM to dose insulin without fingerstick confirmation, and this increased further to 95% by 12 months.
Conclusions
In this study, older adults with T1D had high CGM adherence and trust after 12 months of use. Sharing CGM glucose values with another person could be particularly beneficial in this vulnerable population, however this feature was not adopted by a large majority of participants.
