Effective tight glycemic control (TGC) can improve outcomes, particularly in cardiovascular surgery, but is
difficult to achieve. Variability in insulin sensitivity/resistance resulting from the level and evolution of stress
response, particularly early in a patient’s stay, can lead to hyperglycemia and variability, which are associated
with mortality. This study quantifies the daily evolution of the variability of insulin sensitivity for cardiovascular
surgical and all other ICU patients
