Enhancing Digitally Delivered Diabetes Education With Real-Time CGM: A Comparative Study in People With Type 2 Diabetes

The current research study will add continuous glucose monitoring devices to the evidence-based text messaging diabetes education program for patients with type 2 diabetes for 6 months. Results on the effectiveness of this intervention will be compared for non-insulin using patients.

Detailed Description

The current research study seeks to investigate the impact of incorporating Continuous Glucose Monitoring (CGM) into the evidence-based text messaging diabetes education program, Dulce Digital, focusing on individuals with Type 2 Diabetes (T2D) who are not on insulin therapy. This innovative approach stems from the rationale that real-time continuous glucose monitoring (CGM) can offer valuable insights into glycemic control, thereby enhancing diabetes self-management. In standard care, individuals with T2D, particularly those not on insulin, may not routinely have access to CGM devices. The CGM device, an integral part of recommended diabetes therapy, is FDA approved for use in all people with diabetes. However, reimbursement for CGM devices varies by health plans, and currently, Centers for Medicare & Medicaid Services (CMS) does not reimburse for their use in non-insulin-using diabetes, except in cases of repeated severe hypoglycemia. Despite this, the investigators hypothesize that there are both clinical and financial benefits to providing a CGM device during diabetes self-management education for individuals with non-insulin-using T2D. This study aims to determine if adding a CGM device for this patient category yields significant benefits, contributing to the understanding of the potential advantages and informing future diabetes care practices.

Design Details

  • Primary Purpose: Supportive Care
  • Allocation: Randomized
  • Interventional Model: Parallel Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: CGM Group
Participants will be provided continuous glucose monitors (Dexcom G7) to monitor blood glucose for the entire duration of this study (i.e., one new device every 10 days for a total of 18 devices to last up to 6 months).
Other: Dulce Digital Text Messaging Intervention

Text-based education support program:

  • Participants will receive text messages about diabetes and how to take care of diabetes and health. Participants will receive 2-3 messages every day for first 3 months, and then will slowly decrease over the last 3-months.
  • Participants will also receive text messages that will ask them to test their blood sugar and text back blood sugar reading.
Other: CGM Device
Participants will be provided continuous glucose monitors (Dexcom G7) to actively monitor blood glucose for the entire duration of this study (i.e., one new device every 10 days for a total of 18 devices to last up to 6 months). In addition, participants will attend an information session (group or individual; in-person or virtual) that will provide instructions on using continuous glucose monitors.
Other: Usual Care Blood Glucose Monitoring Group
Participants will use standard blood glucose monitoring devices that are covered by health insurance.
Other: Dulce Digital Text Messaging Intervention

Text-based education support program:

  • Participants will receive text messages about diabetes and how to take care of diabetes and health. Participants will receive 2-3 messages every day for first 3 months, and then will slowly decrease over the last 3-months.
  • Participants will also receive text messages that will ask them to test their blood sugar and text back blood sugar reading.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
HbA1c
Time Frame: 6 months
Measures participants A1c using lab results provided from healthcare provider.
6 months

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
CGM Metric Time in Range
Time Frame: 6 months
Measures the percentage of time a participant's blood glucose levels stay within the target range using CGM device.
6 months
CGM Metric Time above Range
Time Frame: 6 months
Measures the percentage of time a participant's blood glucose levels exceed the target range using CGM device.
6 months
CGM Metric Time Below Range
Time Frame: 6 months
Measures the percentage of time a participant's blood glucose levels fall below the target range using CGM device.
6 months
Summary of Diabetes Self Care Activities (SDSCA) Survey
Time Frame: 6 months
Summary of Diabetes Self Care Activities Survey measures frequency and consistency of diabetes self-care activities during the past 7 days. Possible scores range from 0 (0 Days to 7 (7 Days). Higher scores indicate better compliance with diabetes self-care.
6 months
Diabetes Distress Scale
Time Frame: 6 months
The Diabetes Distress Scale measures four critical dimensions of diabetes distress for participants: emotional, burden, regimen distress, interpersonal distress and physical distress. Possible scores range from 1 (Not a Problem) to 6 (A Very Serious Problem) with higher scores indicating higher levels of diabetes-related distress.
