1040-P: Feasibility and Performance of Continuous Glucose Monitoring (CGM) to Guide Computerized Insulin Infusion Therapy in Cardiovascular Intensive Care Unit (CV-ICU)

We evaluated the utility of real-time CGM for titrating intravenous (IV) insulin via a validated institutional computerized insulin infusion (CII) algorithm in the CV-ICU. We used a hybrid approach of combining CGM with periodic point-of-care blood glucose (POC-BG) tests to validate the continued accuracy of CGM. We also surveyed nurses on this care change. Dexcom G6 CGMs were applied to 61 post-surgical patients with hyperglycemia (34% with diabetes) receiving IV insulin. CGM values were validated with POC-BG every(Q) 1-2 h per the CII protocol. Once validated (i.e., within 20% of POC-BG values if BG ≥100 mg/dL or within 20 mg/dL if BG
