The Dexcom Community Glucose Monitoring Project: Six-Month Results Using Continuous Glucose Monitoring in Type 2 Diabetes

Topic: Type 2 Diabetes, Primary Care, Lifestyle Modification

Key question: What are the benefits of a glucose sensor in type 2 diabetes in a real-world primary care setting?

Research Spotlight: “The Dexcom Community Glucose Monitoring Project: Six-Month Results Using Continuous Glucose Monitoring in Type 2 Diabetes” Grace T, et al. Clin Diabetes. 2024.

Background: Glucose sensor use is limited in the primary care setting despite the multiple benefits of continuous glucose monitoring (CGM) among people with type 2 diabetes.

Main outcomes of the study:

Participants using a glucose sensor (n=237) showed clinically meaningful and statistically significant (p<0.001) decrease in A1C of 2.4%+1.9% at 6 months. Overall, those with higher baseline A1C achieved greater reductions in A1C at the 6-month follow-up.
TIR 70-180 mg/dL significantly increased in the glucose sensor group by 5.5%±28.7% (p=0.022). The improvement in TIR was attributable to a significant decrease in TAR >180 mg/dL (p=0.021).
The proportion of glucose sensor participants meeting Healthcare Effectiveness Data and Information Set (HEDIS) A1C Target of < 8.0% increased from 18.6% to 82.7% at 6 months.

Key takeaways for healthcare providers:

Glucose sensor use in a real-world primary care type 2 diabetes population improved A1C and resulted in a greater proportion meeting A1C targets.
Expanded use of glucose sensors in the primary care setting could help more patients learn about their diabetes, make and sustain lifestyle modifications, and achieve glycemic targets.

Is your patient on a connected pump device?

Yes

By submitting the above form, I certify that I am a licensed practitioner, authorized to receive and dispense samples of the Dexcom G6 Continuous Glucose Monitoring System and/or Dexcom‘s next generation product, Dexcom G7 (the "Samples"). I represent that I am requesting the Samples for evaluation purposes and that I will not (i) sell, resell, barter, return for credit or seek reimbursement for the use of the Samples, or (ii) for professional services for dispensing or evaluating the Samples, I also agree to inform my patients that they should not submit claims for reimbursement to any third party for any Samples.

The Samples are FDA cleared for use with a compatible smart device or separate piece of durable medical equipment called a receiver. Neither devices nor receivers are included in the Samples. Accordingly, and in light of the applicable G6 or G7 Dexcom Instructions for Use, you should dispense Samples only to a patient who (or whose authorized caregiver), in the exercise of your clinical judgment, (i) has reliable access to a compatible smart device and/or automated insulin delivery system, and (ii) is capable of safely using the Samples with their smart device, without the need for a separate dedicated receiver.

Please note that Medicare will reimburse for sensors only if the beneficiary also uses a receiver covered by Medicare. Accordingly, it is appropriate to give Samples to Medicare patients only if they have (in the case of the G6 Samples) or would be eligible to obtain (in the case of the G7 Samples), a Medicare-covered receiver.

You agree that you will not provide the Samples to any patients that are beneficiaries under the Maine or Colorado state Medicaid programs. I understand that Dexcom will be tracking, and if necessary, reporting and may be subject to disclosure requirements with respect to the provision of these Samples. I agree not to reuse any Samples. I acknowledge that Dexcom provides no warranties for the Samples other than the warranties outlined in the applicable Dexcom Instructions for Use. I will comply with all applicable federal, state and local laws in receiving and dispensing these Samples, and I agree to store and use these Samples in a manner consistent with the applicable Dexcom Instructions for Use.
