CGM Utilization With IV Insulin EndoTool and Subcutaneous Insulin in the Neuro ICU

The goal of this study (CGM utilization with IV Insulin EndoTool and Subcutaneous Insulin in the Neuro ICU) is to understand how CGM technology utilized in conjunction with EndoTool IV insulin could improve glycemic management in the NeuroICU, specifically in predicting and preventing hypoglycemic and hyperglycemic episodes with resultant improvement in patient morbidity and mortality. The second arm of the study will focus on how CGM technology utilized in patients on basal bolus subcutaneous insulin while on high dose glucocorticoids could impact glycemic management. The main questions it aims to answer are: 1. Is CGM technology data accurate compared to the current standard point of care among NeuroICU patients? 2. How CGM technology could improve glycemic management in the critical care setting, specifically in predicting and preventing hypoglycemic episodes with IV or subcutaneous insulin? 3. How CGM technology could help treating hyperglycemia in the NeuroICU with resultant improvement in patient morbidity, mortality, and length of stay?
