Intensive insulin therapy in the ICU: is it now time to jump off the bandwagon?

Following the publication of the Leuven Intensive Insulin Therapy (IIT) study in 2001, tight glycemic control has become regarded as the standard of care in intensive care units throughout the world. The Leuven IIT study, was however, an unblinded, single center study with unique patient and institutional characteristics that may not extrapolate to practice elsewhere in the world. Indeed, recent randomized controlled studies have been unable to demonstrate any benefit from tight glucemic control. We suggest that the widespread adoption of tight glycemic control be abandoned at this time.
