Effect of the Use of Continuous Glucose Monitoring Versus Standard Glycemic Control in Hospitalized Patients with Type 2 Diabetes.

Patients use FSL2 and a smartphone. Libreview app will be used to assess interstitial glucose, alarms, and trend arrows, and LibreLinkUp app for research team. Concurrently, CG will be performed using the FreeStyle Optium Neo glucometer from Abbott. The nursing staff will be trained to manage and respond to alarms and trend arrows according to established protocols. The basal insulin adjustment protocol establishes with fasting and premeal targets between 140-180 mg/dL. For prandial insulin, corrective guidelines set according to each patient sensitivity factor, with additional adjustments for the intervention group based on trend arrows. The hypoglycemia alarm sets below 85 mg/dL. If activated, nursing staff will confirm the value via CG. If values are below 70 mg/dL, follow hypoglycemia protocol and if below 100 mg/dL with a descending trend arrow, 15 grams of slow-acting carbs. The hyperglycemia alarm will be set above 300 mg/dL and nurse inform investigators to make decisions.
