Hyperglycemia is an increasingly common and often complex condition to manage in the inpatient setting. Numerous clinical trials have demonstrated associations between uncontrolled diabetes and poor clinical outcomes in a number of inpatient settings. Insulin remains the treatment of choice for the majority of hyperglycemic hospitalized patients and should be prescribed in a physiologic manner, employing basal and bolus insulin. Intravenous insulin should be used liberally in the ICU setting where randomized studies have demonstrated improved outcomes. Recommendations for insulin use in the inpatient setting are provided.
