Accuracy of Real-Time Continuous Glucose Monitoring System in Hospitalized Patients with Diabetes and Chronic Kidney Disease

OBJECTIVE: Real-time continuous glucose monitoring (CGM) systems are beneficial for patients with diabetes by providing a comprehensive assessment of glycemic status and reducing hypoglycemia. However, their performance in patients with both diabetes and chronic kidney disease (CKD) during hospitalization remains unclear. This study aimed to evaluate the accuracy of real-time CGM in hospitalized patients with diabetes and CKD. RESEARCH DESIGN AND METHODS: ) into G1-2 (≥60), G3 (30-59), and G4-5 (99% of values within clinically acceptable zones. CONCLUSIONS: The Dexcom G6 demonstrated reliable accuracy in hospitalized patients with diabetes and CKD, with better performance in advanced CKD. These findings support its clinical utility in this population.
