Trial of CGM Technology in Persons Living With Prediabetes

Trial of Continuous Glucose Monitoring (CGM) Technology in Persons Living With Prediabetes

Continuous glucose monitor (CGM) technology has become increasingly prevalent in the population and has the ability to transform care of patients living with prediabetes. While the technology was initially utilized primarily by patients living with type 1 diabetes using insulin pump therapy, it has become more widely used as part of care in patients living with type 1 or 2 diabetes on any kind of insulin therapy.

Additional investigation is strongly needed to further evaluate the health impacts of CGM technology in persons living with prediabetes. This study is looking to study the impact that CGM technology could have on glycemic control in patients with prediabetes, as well as secondary outcomes, such as blood pressure, weight, and patient insight into their condition and the effect on lifestyle interventions on glycemic control. The primary objective of this study is to determine the effect of CGM technology on glycemic control in patients with prediabetes, measured by the endpoints of A1c and CGM data. Specifically, CGM data will include Time-In-Range (TIR), Time-AboveRange (TAR), Time-Below-Range (TBR), Glycemic management indicator (GMI), and variability measures. Secondary endpoints include blood pressure, weight, and standardized survey data assessing behavioral modifications as a result of CGM technology.

Inclusion Criteria:

• Subjects affiliated with one of the two institutional ambulatory clinics participating in this study who are meeting criteria for prediabetes listed on American Diabetes Association website, which includes A1c = or > than 5.7% and < or = 6.4%, who also have reliable access to a smartphone device compatible with the CGM application
• Greater than or equal to 18 years old

Exclusion Criteria:

• Subjects who have been diagnosed with type 1 or type 2 diabetes mellitus, as defined as A1c > or = 6.5%
• Subjects who do not have reliable access to a smartphone device compatible with the CGM application
• Pregnant patients
