Determine if routine BG testing at the time of ICU admission is being done on all patients, irrespective of a prior diagnosis of diabetes mellitus, and whether it provides clinically important information.

This prospective, observational study was performed in the medical-surgical ICU of a single hospital within a large multi-specialty healthcare system.
