“…Diabetes mellitus is a common comorbidity in patients admitted to the hospital, and the maintenance of good glycemic control is an important objective when patients with diabetes are admitted to the hospital for non-diabetes-related illnesses. Suboptimal glycemic control may contribute to volume and electrolyte changes, poor wound healing, immune suppression, and neurological sequelae (Fischer, Lees, & Newman, 1986;Hostetter, 1990;Hostetter, Lorenz, Preus, & Kendrick, 1990;Mak, Mah, Tey, Sin, & Chia, 1993;Rossini, 1976;Strand, Garcia, & Costales, 1987;Walters, 1984). Additional evidence suggests that strict prevention of hyperglycemia can favorably influence morbidity and mortality from acute illness, such as during an acute myocardial infarction or in the critical care unit (Malmberg, 1997;Van den Berghe et al, 2001).…”
