High blood glucose levels in surgical patients with diabetes are associated with increased risk of medical complications and death. Improved glucose control with insulin injections may improve clinical outcome and prevent some of the hospital complications. In patients who have undergone surgery, high blood glucose increases the risk of wound infection, kidney failure and death. It is not known; however, what is the best insulin regimen in patients who will undergo surgery. The use of repeated injections of regular insulin is commonly used for glucose control in hospitalized patients with diabetes. Recently, the combination of Lantus® and Apidra® insulins has been shown to improve glucose control with lower rate of hypoglycemia (low blood sugar). We hypothesize that in patients with type 2 diabetes admitted to general surgery wards, treatment with once daily glargine (Lantus) plus supplemental glulisine insulin (Apidra®) will produce better glycemic control and a lower rate of hospital complications than treatment with regular insulin per sliding scale (SSRI). The present study aims to determine which insulin treatment is best for glucose control in hospitalized patients with diabetes. Glargine and glulisine insulins are approved for use in the treatment of patients with diabetes by the FDA.
