The 14th International Conference on Advanced Technologies & Treatments for Diabetes (ATTD 2021) took place last month with all sessions presented virtually. Registration is still being accepted to view recorded sessions until September 5, 2021 via https://attd.kenes.com/. This is a premier conference to showcase diabetes technology!
The MOBILE Study (Continuous Glucose MOnitoring in T2D Basal InsuLin UsErs) was presented at ATTD by Dr. Thomas Martens.1 This multi-center randomized controlled trial (RCT) enrolled adults ages 30+ years with type 2 diabetes who have their diabetes managed by primary care providers (n=175). Study inclusion criteria included basal-only insulin use for at least 6 months, an A1C of 7.8-11.5% and completing blood glucose meter (BGM) checks at least 3 times per week. Participants were randomized in 2:1 ratio to either continuous glucose monitoring (CGM) or BGM (daily fasting and post-prandial checks) for the duration of the 8-month study. Participants in the CGM group were able to use BGM to verify CGM readings as needed.
Both study groups had the same number of follow-up research visits and primary care visits. At the end of the MOBILE study, participants in the CGM group (n=116) achieved an A1C reduction of 0.4% more than the BGM group (n=59) (p<0.001). The CGM group achieved 59% Time-in-Range (TIR) of 70-180 mg/dL compared to BGM group TIR of 43% (blinded CGM assessment) (p<0.001). Improvement in A1C and TIR in the CGM group was present across all different demographics such as age groups, baseline A1C and education levels. The study population was racially and socioeconomically diverse. There was one participant in each study group who experienced a severe hypoglycemic event and one participant in the CGM group who experienced diabetic ketoacidosis.
Prior to the MOBILE study, there was less research evidence regarding the benefits of CGM use in people living with type 2 diabetes compared to its use among those living with type 1 diabetes.2 Since type 2 diabetes is much more common than type 1 (n=>34 million type 2 in US) and considering the overall trends for glucose control are getting worse in the US,3 now is the time to talk with patients living with type 2 diabetes about the benefits of CGM if you haven’t already.
The Guardian™ Connect system by Medtronic is a CGM that requires a prescription and is indicated for continuous or periodic monitoring of glucose levels in the interstitial fluid under the skin, in patients 14 to 75 years of age with diabetes mellitus. The system is intended to complement, not replace, information obtained from standard blood glucose monitoring devices, and is not recommended for people who are unwilling or unable to perform a minimum of two meter blood glucose tests per day, or for people who are unable or unwilling to maintain contact with their healthcare professional. The system requires a functioning mobile electronic device with correct settings. If the mobile device is not set up or used correctly, you may not receive sensor glucose information or alerts. For complete details of the system and its components, including warnings, contraindications, and precautions, please consult the user guide at http://www.medtronicdiabetes.com/support/download-library/user-guides and important safety information. Contact your local Medtronic Diabetes representative for more information including how to have a patient evaluate this system free-of-charge for 30 days!
Clinical guidelines were recently completed by researchers on behalf of the American Association of Clinical Endocrinologists (AACE) regarding the use of advanced diabetes technologies.4 These guidelines are intended to assist medical decision-making by health professionals who work with people who live with diabetes mellitus. When following these guidelines, practitioners are also encouraged to use their best clinical judgement while considering individual patient situations.
A total of 357 references were included as a part of these guidelines. Research papers identified through literature review were systematically graded A (strongest), B, C, or D according to various measures such as study design and analysis of data. Recommendations were made based on the strength of evidence. The advanced technologies included were continuous glucose monitoring (CGM), insulin pumps and smart insulin pens. Blood glucose meters and conventional insulin pens were not included.
Examples of the strongest evidence and recommendation include:
While insulin pumps and CGM have been available for several years and a wide array of evidence exists for their use, smart pens are new to this technology world. Less evidence exists, however in the few short years they have been available, this recommendation has been made by AACE:
The goal at Medtronic Diabetes is to help reduce the burden of living with diabetes by offering innovative technology that can help address a full array of needs. Our family of solutions includes:

*Refers to SmartGuardTM Auto Mode. Some user interaction required. Individual results may vary.
** Injection port lets you take your medication without having to puncture your skin for each shot.
◊ Smart insulin pens connect to a mobile app to provide dosing calculations, reminders and CGM system integration.
***The MiniMedTM 770G system is enabled for future software upgrades, when such software upgrades are available. Customers will be offered a software upgrade at no charge through December 2021.* *Program eligibility requirements and terms and conditions apply. Subject to change.
