Can Glucose Monitoring Improve (CGMi Study)
The purpose of this 2-year randomized controlled trial (RCT) is to implement and evaluate a family-focused behavioral teamwork intervention aimed at overcoming barriers to sustained continuous glucose monitoring (CGM) use in youth with type 1 diabetes (T1D). We hypothesize that CGM implemented with a family-focused, behavioral teamwork intervention will result in sustained CGM use and greater improvement in A1c compared to routine implementation of CGM.

- Change in glycemic control, assessed by hemoglobin A1c [ Time Frame: Baseline and 1 year ] [ Designated as safety issue: No ]
- Change in psychosocial factors (e.g., self-efficacy, fear of hypoglycemia, quality of life, diabetes-specific family conflict, diabetes responsibility sharing, diabetes-specific burden, anxiety, depressive symptoms) [ Time Frame: Baseline and 1 year ] [ Designated as safety issue: No ]
- Change in glycemic control, assessed by hemoglobin A1c [ Time Frame: 1 year and 2 years ] [ Designated as safety issue: No ]Durability of the intervention will be assessed by change in A1c from 1 year to 2 years

No Intervention: CGM-Usual Care
Behavioral: CGM Family Teamwork Intervention
The family-focused behavioral intervention targets barriers associated with sustained CGM use in youth with type 1 diabetes. During months 1-18, families in the intervention group will participate in the intervention at each study visit for about an additional 30 minutes.
Consistent CGM use in youth with T1D has been difficult to sustain historically. Youth with T1D and their families have routinely felt burden related to the introduction of this technology into their care management. Additionally, there can be difficulties with calibration, skin irritation, frequent skips, excessive or nuisance alarms and inaccurate readings which often lead to diminished use or discontinuation entirely. The purpose of this protocol is to implement and evaluate a family-focused behavioral teamwork intervention aimed at overcoming barriers to sustained CGM use in youth with T1D. In this 2-year RCT, we will assess the long-term acceptability and durability of CGM use and its associated glycemic and psychological outcomes in youth with T1D and their families. We will randomize 120 families to one of two groups: (1) CGM implemented according to usual care (CGM-Usual Care, CGM-UC) or (2) CGM implemented with a family teamwork intervention (CGM-Teamwork, CGM-TW). This intervention will allow participants and families to overcome barriers to sustained CGM use and achieve glycemic benefits that have been afforded to adults using CGM as demonstrated in other research. In year 1, all CGM supplies will be provided and covered by study resources. In year 2, study participants will be asked to cover the costs associated with sensor use and any costs associated with replacement of CGM components in a manner consistent with routine clinical care as the investigators believe that it is important to assess durability of CGM use in clinical practice.
