Introduction

The American Diabetes Association (ADA) Standards of Medical Care (SOC) in Diabetes provides one of the most respected and current guidelines for diabetes care. Updated annually, the recommendations are intended to provide clinicians, patients, researchers, and payers with the components of diabetes care, general treatment goals, and tools to evaluate the quality of care, as well as guidelines for medical, pharmaceutical and lifestyle management.

Grading of Clinical Evidence - “A” ratings are based on large well-designed clinical trials (meta-analysis, RCTs, multi center trials) and considered the strongest category. “B” (well-conducted cohort studies) and “C” (poorly controlled or uncontrolled studies) ratings are given for supportive evidence, not as strong as “A.” An “E” rating is given for expert consensus or clinical experience (no evidence from clinical trials).

Recommendations

Real time continuous glucose monitoring (RT-CGM) (A) or intermittently scanned continuous glucose monitoring (IS-CGM) (B) should be offered for diabetes management in adults with diabetes on multiple daily injections (MDI) or continuous subcutaneous insulin infusion (CSII).	RT-CGM (B) or IS-CGM (E) should be offered for diabetes management in youth with type 1 diabetes on MDI or CSII who are capable of using the device safely (either by themselves or with a caregiver).	Initiation of CGM, CSII or Automated Insulin Delivery (AID) early in the treatment of diabetes can be beneficial. (C)
In patients on MDI and CSII, RT-CGM devices should be used as close to daily as possible for maximal benefit. A IS-CGM devices should be scanned frequently, at a minimum once every 8 h. (A)	Periodic use of RT-CGM or IS-CGM or use of professional CGM can be helpful for diabetes management in circumstances where continuous use of CGM is not appropriate, desired, or available.¹ (C)	RT-CGM (A) or IS-CGM (C) can be used for diabetes management in adults with diabetes on basal insulin.
AID systems should be offered for diabetes management to youth and adults with T1D. (A)	Systems that combine technology and online coaching can be beneficial in treating pre-diabetes and diabetes for some individuals. (B)	Insulin pump therapy can be offered for diabetes management to youth and adults on MDI with T2D. (A)

Discussion Points

Updated guidelines state CGM should be offered for all adults on MDI and CSII who are capable of using the device safely.

The ADA strengthened its language recommending CGM for all adults on insulin, now stating that CGM “can be used” by those on basal-only therapy.

RT-CGM (B) or IS-CGM (E) should be offered for diabetes management in youth with T1D on MDI or CSII.

Key Insights

The ADA supports the “Beyond A1C” movement, noting, “Time in Range, time below range, and time above range” are all useful tools for guiding changes in therapy; this can help providers gain more insight into their patients’ glycemic control and provides more personalized and actionable care.²
The ADA also strengthened its language recommending CGM for all adults on insulin, now stating that CGM “can be used” by those on basal-only therapy.
Given that A1C does not provide information on glycemic variability, the use of CGM-derived metrics can help patients identify variability to reduce their risk of hypoglycemia.²
Consistent with other studies we have seen³, the ADA states that early initiation of CGM can be beneficial.
The ADA is starting to recognize digital coaching and digital self management as effective methods in diabetes care.
While RT-CGM and IS-CGM both have been recognized by the ADA in the same category, important benefits of RT-CGM have been noted in recent studies, supporting higher level of evidence of its use.^4,5

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.
