Description détaillée
The purpose of this pilot project is to evaluate the effectiveness of a behavioral economic intervention to increase use of continuous glucose monitors (CGM) in adolescents and young adults with T1D. This study will be done in conjunction with Nancy Petry, PhD and her research team at University of Connecticut School of Medicine (UConn Health). The intervention will reinforce patients for wearing CGM and for uploading it and reviewing its data. A 6-month pilot trial will be conducted with up to 20 patients receiving the intervention. The specific aims are:
- To estimate how well a reinforcement intervention increases usage of CGM. The proportion of days on which participants wear the CGM will be determined as well as the number of weeks during which CGM is worn at least 5 days. We will compare usage rates in the pilot trial to historical control data of patients initiating CGM.
- To evaluate the association between CGM usage and A1c. We expect A1c will decrease over time in patients who receive the reinforcement intervention. Patients who continue using the CGM are expected to have greater decreases in A1c than patients who discontinue its usage.
Evaluations will be conducted at time of CGM initiation, and 6, 13, 19, 26, and 39 weeks after treatment initiation to assess effects of the intervention and estimate effect sizes.
In addition to the primary aims, secondary outcomes will also be evaluated. Continued use of CGM is expected to improve aspects of diabetes management and daily functioning. Predictors of continued CGM usage and improvements in A1c will also be evaluated.
Results from this pilot study will be instrumental for guiding a subsequent, larger and longer term randomized study for evaluating reinforcement interventions for improving uptake of CGM, other diabetes-related adherence behaviors, and long-term outcomes.

Change in the Proportion of days participants wear the CGM
Délai: up to 39 weeks
|
CGM data uploaded to a CGM tracking website (e.g., Dexcom CLARITY™, Carelink) will be used to calculate the change in the proportion of days when the patient wore the CGM.
At the 6, 13, 19, 26 and 39 week study visits, data will be uploaded and exported into an Excel file to calculate the days.
