Glucose variability and mortality
In this single center retrospective cohort of a med/surg ICU over 4 years, researchers found higher mortality in patients with the highest mean glucose change per hour (a measure of variability). The odds of ICU death was higher for each quartile of mean glucose change per hour, compared to each quartile of mean glucose, indicating that glucose variability may be more important a factor for death than the mean glucose. Consistency of glucose control may be more important than absolute control (abstract)
