This study provides data in a critically ill patient population, all of whom received IV insulin, and demonstrates significant reduction in POC testing, a fair degree of sensor accuracy and maintained patient safety. Although it would be of interest to formally compare various hybrid approaches, our data suggest that more liberal criteria can be applied to a hybrid protocol, including earlier use as soon as CGM validation is achieved, reduced frequency of POC BG monitoring, and nonadjunctive use (eg, for dose titration). A prospective multicenter study in a more diverse population of critically ill patients is needed.
