Perioperative Continuous Glucose Monitoring

A Pilot Trial of Continuous Glucose Monitoring (CGM) Technology in Preoperative Assessment Clinic

To evaluate use of continuous glucose monitoring (CGM) technology in the preoperative setting: evaluate feasibility of placement of CGM during preoperative clinic visit with intent to utilize CGM throughout perioperative period.

To further study potential barriers related to loss of continuous glucose monitoring (CGM) data as it relates to use of electrocautery and grounding devices utilized in the perioperative setting. To assess how CGM technology could improve glycemic management in the perioperative setting, specifically in predicting and preventing hypoglycemic episodes as well as utilization for treating hyperglycemia with resultant improvement in patient morbidity, mortality, length of stay, and overall quality of life. CGM technology aids tremendously in data collection with recognition of glycemic patterns, as well as evaluating prediction of blood glucose changes including both hyperglycemic and hypoglycemic events. The availability of such a large volume of glycemic data has been shown to make a tremendous impact in patient care, resulting in statistically significant reductions in hemoglobin A1c, a decrease in hypoglycemia, a decrease in hospital admissions for diabetes complications, and improved overall quality of life and fear of hypoglycemia in patients using CGM technology.
