Inpatient Diabetes Management in the Twenty-First Century.

In hospitalized patients, both hyperglycemia and hypoglycemia have been associated with poor outcomes. During the inpatient period, hyperglycemia has been associated with increased risk of infection, cardiovascular events, and mortality. It is also associated with longer length of hospital stay. Hypoglycemia has also been associated with an increased risk of mortality. Therefore, current evidence supports avoidance of both conditions among hospitalized patients whether they are admitted to critical care units or noncritical care units.
