Context: The CDC estimates that 45% of U.S. citizens have either diabetes or prediabetes (PD); combined medical cost and lost productivity in United States was $327 billion, with the majority spent on diabetic complications. A continuous glucose monitoring system (CGMs) is clinically useful in patients with type 2 diabetes (T2DM) and PD and is strongly linked with increased adherence to lifestyle changes. If the temporary use of a CGMs as an adjunct to therapeutic lifestyle change education is beneficial, this may preempt and mitigate medical costs and loss of productivity, adding another valuable tool for primary care providers. Objective: To evaluate the potential of a temporary CGMs during participation in an intensive therapeutic lifestyle medicine program (ITLMP) to improve compliance with healthy lifestyle change for people with T2DM and PD, by identifying logistical and technical barriers, and perceived usefulness of CGMs for the patient. Human Subjects Review: Approved by the Ohio University Institutional Review Board. Design: Feasibility study. Setting: During an outpatient ITLMP in a medium-sized hospital system in Appalachia Ohio, 15 consenting participants with T2DM or PD will temporarily wear a CGMs continuously for 10 weeks, complete food and exercise logs and enter daily reflections on the visible effects of food consumed and exercise on their blood sugar level. Intervention/Instrument: The Dexcom CGMs will be utilized to measure sugar levels of the interstitial fluid of the subcutaneous tissue, which correlates with blood glucose levels. Diabits, an app developed by Bioconscious, installed on the participant’s smart phone to collect data will provide feedback to the subject, as well as generate a summary report for analysis. Outcome Measures: Identify logistical and technical barriers and perceived benefits to participants. Anticipated Results: This study will identify barriers for temporary use of a CGMs in the setting of an ITLMP, and provide perceived benefits to subjects. Conclusions: Determine if a CGMs temporarily used in the setting of an ITLMP is feasible, leading to a larger controlled study to evaluate benefit and potential cost savings.
