Inpatient management of hospitalized patients with type 2 diabetes.

Over the past 4 years, the scientific literature addressing issues relevant to inpatient hyperglycemia and its management has grown dramatically but remains incomplete. The growing interest in inpatient diabetes management is particularly pertinent given the epidemic rise in the prevalence of type 2 diabetes and the associated increase in the proportion of inpatients carrying this diagnosis. The benefits of aggressive glucose control are well-established in certain admission categories. These benefits likely apply to many other admission diagnoses, but remain unproven at this time. Similarly, the best methods of glucose control remain uncertain in the various inpatient settings. Intensive insulin infusion therapy is becoming the standard care in the intensive care unit setting. Its use is also growing in less acute inpatient settings but requires further study. Inpatient subcutaneous insulin recommendations are general based on experience gained in the outpatient setting but offer a practical, physiologic approach.
