1794-PUB: Potential for Improving CGM Systems? Anticipated Benefits from Increasing the Glucose Prediction of Current CGM Algorithms

Abstract

Current CGM algorithms allow a glucose prediction up to 30 minutes. To elaborate on the potential to improve current CGM systems, we investigated if a possible increase in this prediction window to up to 2 hours would be perceived as a significant benefit. People with type 1 and type 2 diabetes currently using a CGM system were invited to participate. Participants were presented with a scenario depicting the potential of a hypothetical CGM algorithm to predict the course of glucose for up to 2 hours. They were instructed to imagine how such a long-term prediction would affect their diabetes management. They were asked to complete the T1-Diabetes Distress Scale (T1-DDS) and the Hypoglycemia Fear Survey (HFS-II) and rate each item regarding the perceived potential change from using such a long-term prediction (scale: -2 strong deterioration, -1 deterioration, 0 no change, 1 improvement, 2 strong improvement). 206 people participated (29.1% type 2 diabetes). Participants expected moderate improvements in hypoglycemia and management distress (Box plots shown in Figure 1 for T1-DDS). Similar improvements in HFS-II scores (0.57±0,49) were seen with no differences between diabetes types. Increasing the glucose prediction to up to 2 hours would be seen as a potential improvement regarding reductions in hypoglycemia distress and fear of hypoglycemia by both people with type 1 and type 2 diabetes.
