Improving Blood Glucose Control With a Computerized Decision Support Tool: Phase 1

Inclusion Criteria: 1. Pediatric ICU: Proposed indications by pediatric clinicians at participating ICUs for glucose control in their ICUs would include patients who require mechanical ventilation for greater than 24 hours and/or require a vasoactive infusion (e.g. dopamine \>3 mg/kg/min, dobutamine, epinephrine, or vasopressin). 2. Adult ICUs: Proposed indications by clinicians in participating ICUs for glucose control in participating adult ICUs include critically ill patients with an anticipated ICU length of stay of 3 or more days. Exclusion Criteria: 1. Pregnancy (negative pregnancy test required for females of child-bearing age) 2. Age less than one month 3. Inborn errors of metabolism that the clinician suspects will affect glucose homeostasis 4. Acute or chronic liver disease with any documented episode of blood or plasma glucose \<60 mg/dl within the 24 hours prior to study entry 5. Diabetic Ketoacidosis (critically ill patients with insulin dependent diabetes not in ketoacidosis will be eligible if attending physicians intend to use intravenous insulin as part of ordinary care) 6. Severe chronic liver disease (Child-Pugh score \>10)
