About
Insulin infusions are commonly used in hospitalized diabetics to control blood sugar, and they are effective. However, insulin infusions require the use of limited resources. Insulin infusions are therefore changed to insulin shots as a patient recovers. Once an insulin infusion is stopped and shots are started, blood sugar control is harder to maintain. This is, in part, because physicians have different ideas on how to dose insulin shots in hospitalized patients. A math equation has been developed by the research staff that attempts to predict the effective doses of insulin shots in patients whose insulin infusion have just been stopped. The math equation was developed for patients with type 2 diabetes mellitus. In this study, all patients will be treated with the same type of insulin shots, with doses of the insulin shots chosen either by the math equation or by the judgment of the patient's physician. The study will then follow blood sugar values for 24 hours to see if the math equation is effective. If the equation is proven to be effective, a new tool will exist for physicians to determine the best dose of insulin shots for type 2 diabetics. Such a tool would, in turn, allow for widespread use of insulin infusions to determine a patient's insulin needs before discharge from the hospital. Blood sugar control for type 2 diabetics that are inpatient or outpatient would improve as a result, with potentially far reaching public health benefits.
