Abstract: Diabetes technology is changing and has quickly become an integral part of diabetes care and management. Typically, patients will need to wait months due to paperwork, insurance, and logistical issues before utilizing these technologies. With this project, the investigators plan to study the effects of introducing technology to newly diagnosed type 1 diabetes patients. It is hypothesized that early access to flash continuous glucose monitoring (CGM) technology will improve scores in diabetes's measures. The primary outcome with be the parent version of the Diabetes Treatment Satisfaction Questionnaire (DTSQ). Secondary outcomes will include other diabetes measures such as DTSQ teen version, Hypoglycemia Fear Survey (HFS)- Parent and child version, Diabetes Distress Survey (DDS)-parent version, PedsQL- parent and child versions. The study team will also look at other diabetes outcomes including A1c, time in range, and reduction in hypoglycemia.
Background: Type 1 diabetes is a complex disease requiring newly diagnosed pediatric patients and families to learn how to check blood glucoses, inject insulin, count carbohydrates, treat hypoglycemia/hyperglycemia, and perform many other complex tasks, all within the first few days after diagnosis.
Continuous glucose monitors (CGMs) and flash glucose monitors have emerged as important diabetes technologies towards providing improved care and easing the burden of disease. These technologies are most typically introduced to families in the outpatient setting 2-3 months following diagnosis due to logistical issues related to insurance coverage.
Barriers to access include requirements for insurance prior authorization, lack of immediate availability at local pharmacies, need for patient training, and the historical bias towards requiring finger stick glucose monitoring as the basis for diabetes management. Despite these barriers, the data supports the observation that CGM technology provides for better understanding of diabetes, improved quality of life for parents and children, reduced frequency of hypoglycemia, and improved A1c.
This project will potentially show the feasibility of introducing these technologies at diagnosis. New onset type 1 diabetes patients will be randomized to receive either a Freestyle Libre flash glucose monitoring system immediately at diagnosis or to delayed use of CGM (standard of care).
|Study Type :||Interventional (Clinical Trial)|
|Actual Enrollment :||0 participants|
|Intervention Model:||Parallel Assignment|
|Intervention Model Description:||The study team will enroll 52 consecutive new onset type 1 diabetes patients and stratify the subjects into two groups, age 4-10 vs 11-17, aiming for 26 subjects in each group. Participants will be randomized to one of the two groups using blocked randomization with random block sizes of 2 and 4, stratified by age (4-10 vs. 11-17).|

|Estimated Study Start Date :||September 2019|

Active Comparator: Freestyle Libre Group
Freestyle Libre Group: Participants will use the Freestyle Libre flash glucose monitoring system throughout the study for 2-3 months.
Device: Freestyle Libre Blood Glucose Monitor
The intervention arm of this study will begin using the Freestyle Libre glucose monitor within 2 weeks of their diabetes diagnosis
No Intervention: Control Group (standard diabetes care)
This group will receive standard care. At the around 1 week and 2 month visits, control group subjects will use a blinded Freestyle Libre Pro to provide data that can be used to compare glucose variability between groups. The Libre sensor will allow the study team to measure glucose values but the subjects will not have access to this information for management/treatment decisions and usual diabetes care will be unaffected. The Freestyle Libre Pro last 14 days, can be activated in clinic, and the sensor can be returned in person or via mail where the investigators will download the data.
- Change in Diabetes Treatment Satisfaction Questionnaire- Parent version [ Time Frame: 2 weeks,3 months, and 12 months ]Survey for Diabetes treatment satisfaction: 14 question survey with each question scaled from 0-6; with 0 being 'very dissatisfied' and 4 being 'very satisfied'
- Change in Diabetes Treatment Satisfaction Questionnaire- Teen version [ Time Frame: 2 weeks,3 months, and 12 months ]Survey for Diabetes treatment satisfaction: 12 question survey with each question scaled from 0-6; with 0 being 'very dissatisfied' and 6 being 'very satisfied
- Change in Pediatric Quality of Life Survey- Parent and child versions [ Time Frame: 2 weeks,3 months, and 12 months ]Survey for Pediatric quality of life: 33 question survey with each question scaled from 0-4; with 0 being 'never to 4 being 'almost always'
- Change in Problem Areas in Diabetes survey [ Time Frame: 2 weeks,3 months, and 12 months ]Survey for diabetes specific distress: mean item score or 0 - 1.9 should be considered "little or no distress," a mean item score between 2.0 - 2.9 should be considered 'moderate distress,' and a mean item score > 3.0 should be considered 'high distress.'
- Change in Hypoglycemia Fear Survey - Parent and Child Versions [ Time Frame: 2 weeks,3 months, and 12 months ]Survey for fear associated with hypoglycemia: 26 question survey with each question scaled from 0-4; with 0 being 'never' and 4 being 'almost always'
- Change in Diabetes Distress Survey- Parent version [ Time Frame: 2 weeks,3 months, and 12 months ]
The PARENT DDS yields a total diabetes distress score plus 4 subscale scores, each addressing a different kind of distress. To score, simply sum the patient's responses to the appropriate items and divide by the number of items in that scale.
Current research suggests that a mean item score or 0 - 1.9 should be considered "little or no distress," a mean item score between 2.0 - 2.9 should be considered 'moderate distress,' and a mean item score > 3.0 should be considered 'high distress.'
