  Purpose

The aim of the study is to determine whether the use of the CGAOtm software is associated with a decrease in 90-day mortality when compared with the use of standard care methods for glucose control with target blood glucose levels inferior to 180 mg/dl. The CGAOtm software is designed to assist physicians and nurses in achieving tight glucose control (defined by a target for blood glucose levels between 80 and 110 mg/dl) in critically ill patients.

Primary Outcome Measures:
  • All-cause 90-day Mortality [ Time Frame: Day 90 ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • All-cause 28-day Mortality [ Time Frame: Day 28 ] [ Designated as safety issue: Yes ]
  • All-cause Intensive Care Unit Mortality [ Time Frame: Date of discharge from the ICU ] [ Designated as safety issue: No ]
  • All-cause In-hospital Mortality [ Time Frame: Day of discharge from the hospital ] [ Designated as safety issue: No ]
  • Intensive Care Unit Free Days [ Time Frame: 28 days ] [ Designated as safety issue: No ]
    Intensive care unit free days was 28-day-ICU-free-days i.e. was calculated by subtracting the actual ICU duration in days from 28 with patients who died at day 28 or before being assigned 0 free-days and those who had a stay in ICU of 28 days or more being also assigned 0 free-days

  • Time Spent in Blood Glucose Target [ Time Frame: Day of discharge from the ICU ] [ Designated as safety issue: No ]
  • Severe Hypoglycemia [ Time Frame: Date of discharge from the ICU ] [ Designated as safety issue: Yes ]
    Number of patients with severe biological hypoglycemia (defined as blood glucose of 40 mg per deciliter or less)regardless of clinical signs

  • Hospital Length of Stay [ Time Frame: Date of discharge from the hospital ] [ Designated as safety issue: No ]
  • Intensive Care Unit Length of Stay [ Time Frame: Date of discharge from the ICU ] [ Designated as safety issue: No ]
  • Incidence of Nosocomial Bacteriemia [ Time Frame: Date of discharge from the ICU ] [ Designated as safety issue: Yes ]

Arms Assigned Interventions
Experimental: CGAO-based Glucose Control
Use of a Computerized Protocol fot Tight Glycemic Control named CGAO software in order to maintain Blood Glucose Levels between 4.4 and 6.1 mmol/l.
Device: CGAO-based Glucose Control

Use of a clinical computerized decision-support system named CGAOtm designed to achieve tight glucose control in various ICU settings, and fine-tuned to reduce glucose variability without increasing the incidence of severe hypoglycemia or nurse workload.

CGAOtm is based on explicit replicable recommendations following each blood glucose measurement for insulin rates and time to next measurement, and reminders, alerts, graphic tools, trends, and individual on-line data aimed at increasing confidence of the nursing staff in the computer protocol and giving care staff a method for controlling the process during the whole ICU stay, according to a "human-in-the-loop" approach.

The algorithm used in the CGAOtm software for the calculation of the recommended insulin rates derived from a PID (Proportional-integral-derivative) controller, a generic control loop feedback mechanism widely used in industrial control.

Other Name: CGAO, LC_CGAO version1
Active Comparator: Standard-Care Glucose Gontrol
Use of Standard-Care Methods for Glucose Control targeting Blood Glucose Levels inferior to 10 mmol/l.
Device: Standard-Care Glucose Control
Patients in the control group will receive conventional insulin therapy using the "usual care" protocol of each participating centre (already used in the centre before the beginning of the trial and targeting blood glucose levels inferior to 180 mg/dl).
Other Name: Usual care

Criteria

Inclusion Criteria:

  • At time of the patient's admission to the ICU, the treating ICU specialist expects the patient will require treatment in the ICU that extends beyond the calendar day following the day of admission.

Exclusion Criteria:

  • Age < 18 years or patient under guardianship.
  • Pregnancy.
  • Moribund patient or imminent death in the ICU (e.g. patient expected to die in the ICU within 24 hours).
  • At time of the patient's admission, the treating physicians are not committed tu full supportive care.
  • Patient admitted to the ICU for treatment of diabetic ketoacidosis or hyperosmolar state.
  • Patient admitted to the ICU for hypoglycemia.
  • Patient thought to be at abnormally high risk of suffering hypoglycemia (e.g. known insulin secreting tumor or history of unexplained or recurrent hypoglycemia or fulminant hepatic failure).
  • Patient who have suffered hypoglycemia without documented full neurological recovery
  • Patient is expected to be eating before the end of the day following admission.
  • Patient previously enrolled in the CGAO-REA study.
