Introduction and Objective: This pilot study sought to compare glucose outcomes and provider insulin dosing confidence in individuals using personal CGM while in the hospital compared to those receiving point of care blood glucose (POC BG) monitoring only.Methods: Hospitalized individuals followed by the diabetes service and expected to be discharged on insulin were included. Diabetes service providers completed a short Insulin Dosing Confidence Survey after daily rounds. POC BG values were recorded.Results: A total of 247 patient days were included in the survey. POC BG monitoring only = 200, stand-alone CGM =27, and automated insulin delivery systems = 20.Conclusion: Individuals in the standalone CGM and POC BG only groups had similar mean glucose values and percent of glucose values in target range, however no hypoglycemia was observed in either group utilizing CGM compared to 5.4% in the POC BG monitoring only group. This suggests personal CGM may have a role in limiting hypoglycemia in hospitalized individuals. Further study is needed, and efforts should be made to empower individuals to start or continue use of personal CGM while hospitalized.
