Brief summary
This study is to assess an approach of self-management called CloudConnect, evaluating the impact of CloudConnect Reports on patient engagement, adolescent/parent discussion, and clinical outcomes in adolescent Type 1 Diabetes (T1D).
Detailed description
It is hypothesized that in contrast to adolescents randomized to the Control Group subjects will maintain a Hemoglobin A1c (HbA1c) while adolescents randomized to receiving the CloudConnect Report will have a lowering of HbA1c that is related to the increase in adolescent/parent disease-specific engagement. Moreover, the hypothesis is that the subjects receiving the CloudConnect Report will increase the engagement of adolescents/ parent through increased communication and self-management behavior, and that this increase in engagement will lead to improved medical outcomes.
Interventions
Subjects and their parents will be asked to download the data from the study devices as well as download their insulin pump/pen. The participants will receive a weekly CloudConnect Report that is based on analysis of the data gathered from the downloads provided by the subject during that week. Participants will both receive weekly contact from the study team to discuss the communication that the subject & their parent had during the week about the participant's diabetes management.

Intervention model description
Subjects (child/parent dyad, with child and parent counted as separate subjects randomized together) will be randomized to either a Control Group or an Experimental Group. Both groups will use a study CGM and activity tracker. MDI users will use an inPen to dispense their insulin treatment with their personal insulin. Subjects who use an insulin pump to care for their diabetes will use their personal pump and their personal insulin during the study. All subjects will be asked to download their equipment each week. The study team will communicate with both the subject and their parent(s) each week to discuss their diabetes management. Subjects will complete questionnaires at the beginning and end of the study.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Family Communication Inventory Questionnaire | 12-weeks | It is hypothesized that individuals randomized to the Control Group will initially modestly improve management as a result of either of new access to CGM, but it will return to baseline levels by the 12-week evaluation. By contrast, it is hypothesize that individuals randomized to the Experimental Group will benefit from receiving the weekly CloudConnect Report by having increased engagement and communication by 8 weeks that is sustained by 12 weeks (3 months). The communication will be measured by comparing pre- and post-study Family Communication Inventory questionnaire and the weekly communication assessments. The Family Communication Inventory, Frequency scale assesses the amount of times a parent and adolescent communicate regarding insulin dosing. Scores range from 0 to 36, with higher scores reflecting more frequent communication--commonly thought of as a better outcome. |
