Mean Blood Glucose (BG) in mg/dl Among Glucommander Group Compared to Standard Insulin Infusion [ Time Frame: First 10 days of ICU stay ]
Daily mean blood glucose concentrations during insulin infusion with the Glucommander and a standard paper form insulin infusion algorithm are measured every day up until 10 days and a mean values of these levels are calculated. The Mean blood glucose concentrations are measured once the target blood glucose levels are achieved after admission
  • The primary outcome of the study is to determine
  • differences in glycemic control as measured by mean daily blood
  • glucose concentration between treatment groups.

  • Number of Patients With Severe Hypoglycemia Episodes Among the Glucommander Group Compared to Standard Algorithm [ Time Frame: First 10 days of ICU stay ]
    Severe hypoglycemia is defined as the blood glucose (BG) levels lower than 40 mg/dL. The number of patients enrolled among both groups with the reports of having the BG levels lower than 40 mg/dL are recorded for duration of 10 days
  • Mean Length of Intensive Care Unit (ICU) in Days Stay Among Glucommander Group Compared to Standard Insulin Infusion Group [ Time Frame: During ICU hospitalization, up to 30 days ]
    Mean number of days, the patients stayed in the intensive care unit are measured among glucommander group and standard insulin infusion group.
  • Mean Hospital Length of Stay in Days Among the Glucommander Group Compared to Standard Insulin Infusion [ Time Frame: During the complete length of hospitalization, up to 60 days ]
    mean number of days the patients stayed in the hospital are measured among the Glucommander group and standard insulin infusion and compared
  • Secondary outcomes include differences between treatment groups
  • in any of the following measures: number of hypoglycemic events
  • (blood glucose < 60 mg/dl), length of ICU stay and length of hospital stay,
  • and number of hyperglycemic episodes (blood glucose > 200 mg/dl).

Trial Between a Computer-Guided Insulin Infusion Protocol Versus a Standard Insulin Infusion Algorithm in Medical ICU
Trial Between a Computer-Guided Intravenous Infusion Protocol Versus a Standard Insulin Infusion Algorithm in Medical ICU

The study is a multicenter, prospective, open-label randomized study to compare the safety and efficacy of continuous insulin infusion (CII) via a computer-guided(Glucommander) and a standard paper form protocol among the patients hospitalized in a medical intensive care unit (ICU).

Increasing evidence from observational studies in hospitalized patients with and without diabetes indicates that hyperglycemia is a predictor of poor outcome. Blood glucose control with intensive insulin therapy in patients with acute critical illness reduces the risk of multiorgan failure and systemic infection, and decreases short- and long-term mortality.

The use of intravenous insulin infusion is the preferred route of insulin administration for the management of diabetic subjects with diabetic ketoacidosis and nonketotic hyperosmolar state, intraoperative and postoperative care, the postoperative period following heart surgery and organ transplantation, acute myocardial infarction, stroke, and critical care illness. Some of these settings may be characterized by, or associated with, severe or rapidly changing insulin requirements, generalized patient edema, impaired perfusion of subcutaneous sites, requirement for pressor support, and/or use of total parenteral nutrition. In these settings, the intravenous route for insulin administration has been considered superior than the subcutaneous injection of split-mixed regimen of intermediate and regular insulin with respect to rapidity of effect in controlling hyperglycemia, overall ability to achieve glycemic control, and most importantly, preventing hypoglycemic episodes. Recently, several insulin infusion protocols have been reported in the literature; these algorithms and formulas, however, may be confusing and difficult to follow and may increase the risk of dosing errors. To facilitate patients care, insulin algorithms could be placed on a computer and used at the patient bedside to direct the nursing staff administering the intravenous insulin. The Glucommander is one of such computer-derived insulin infusion protocol which has been used successfully in over 5,802 patients with diabetes between 1984 and 1998. The study hypothesizes that management of inpatient hyperglycemia with a computer-guided intravenous infusion protocol will facilitate smoother glycemic control with a lower rate of hypoglycemic events than treatment following a standard insulin infusion algorithm in critically ill patients in medical the ICU. The study also aims to determine differences in glycemic control between treatment with a computer-guided intravenous infusion protocol (Glucommander) and a standard insulin infusion algorithm in critically ill patients in the ICU.

  • Device: Glucommander
    Glucommander is a Computer-guided Intravenous (IV) insulin infusion protocol used for glycemic control in inpatients. This algorithm directs the administration of IV insulin in response to Blood Glucose (BG) measurement at the patient's bedside. In this study, the Glucommander program was loaded into a PalmOne (Zire 31, Tungsten E2 by Palm Inc.) handheld personal digital assistant (PDA) device. During the infusion, the nurse entered BG levels into the system and the computer recommended the insulin infusion rate and a variable time to check the next glucose testing. An alarm prompted the scheduled glucose check. The insulin infusion followed the formula: Insulin/Hour = Multiplier × (BG− 60).
  • Other: Standard insulin infusion algorithm
    Standard insulin infusion Algorithm is a standard paper form insulin infusion algorithm. The algorithm is divided into four columns based on empirically determined insulin sensitivity. The first column was for the most insulin-sensitive patients, and the fourth column was for the most insulin resistant patients. The majority of patients are started in the algorithm 1 column. Insulin resistant patients, such as those receiving glucocorticoids or receiving >80 units of insulin per day as outpatients, started in the algorithm 2 column. The insulin infusion rate was determined by the patient's BG level and was measured hourly until the patient was stable and within the target range. If BG targets were not achieved and the BG had not decreased by at least 60 mg/dL in the preceding hour, the patient was moved to the next column.
