Effects of GlucoClear CGM System on the Performance of Insulin Therapy in Critically Ill Patients (GlucoClearIT)
A Study on the Effects of the Use of GlucoClear CGM System on the Performance of Insulin Therapy in Critically Ill Patients
After providing written informed consent, the first 20 Subjects meeting Inclusion/Exclusion Criteria will be consecutively enrolled in the Standard of Care cohort. The moderate treatment cohort will then be consecutively enrolled, followed by the tight glycemic control cohort.
After sensor insertion, baseline evaluations including APACHE II, SOFA, and laboratory evaluations will be determined.
Subjects enrolled in the standard of care cohort will be treated according to the institution's protocol for measuring glucose and managing insulin. These subjects will be monitored on a GlucoClear System but they will not be managed based on the values or trends of the GlucoClear system.
Subjects enrolled in the treatment cohorts will be monitored and managed with a special version of the GlucoClear continuous monitoring system. This system contains the GlucoClear Insulin Dosing Algorithm providing insulin dosing recommendations to enable the clinician to manage patient glucose within pre-specified target levels. These recommendations are presented on screen for a clinical professional to approve or override.
Subjects in the moderate treatment cohort will have their glucose managed in the range of 120 - 180 mg/dl. Subjects in the tight glycemic control treatment cohort will be managed in the range of 80 - 120 mg/dl.
After discharge from the ICU, subjects will followed for adverse events and mortality at 30 days, either by telephone contact or office visit.

Szczegółowy opis
Hyperglycemia, hypoglycemia and glycemic variability, the three components of dysglycemia are independently associated with morbidity and mortality of critically ill patients. Blood glucose (BG) control with insulin has the potential to decrease morbidity and mortality of intensive care unit (ICU) patients. Blood glucose control with insulin, however, is associated with an increased risk of hypoglycemia and its effect on glycemic variability is uncertain. BG control with insulin utilizing manual systems for glucose measurement is blood-consuming and time-consuming, since frequent blood draws for glucose measurements are necessary in order to achieve blood glucose control.
Severe hypoglycemia (blood glucose level < 40 mg/dl) is a feared complication of blood glucose control with insulin. Undoubtedly, with implementation of blood glucose with insulin the incidence of hypoglycemia increases. Reported incidences of severe hypoglycemia rise by 5 to 10-fold as compared to conventional glucose control strategies in randomized controlled trials. Several reports showed a significant association between hypoglycemia and patient outcomes. Recently, an association has even been suggested between moderate and mild hypoglycemia (blood glucose level between 40-69 mg/dL) and patient outcomes. Incidences of moderate hypoglycemia are more prevalent than severe hypoglycemia. The risk of developing (severe or moderate) hypoglycemia hampers, at least in part, broad implementation of blood glucose control with insulin, in particular when aiming at normal blood glucose levels [17,18].
Recent studies showed also significant associations between glycemic variability and patient outcomes. BG control algorithms, if properly applied, could decrease glycemic variability. Experimentally, rodent experiment showed that brain damage was not associated with the duration of severe hypoglycemia, but instead with its correction (mainly overcorrection) with intravenous dextrose causing formation of radicals. Hence, a close glucose monitoring to prevent overcorrection is mandatory.
These different arguments strongly support the need for reliable and accurate CGM. The GlucoClearTM Continuous Glucose Monitoring system from Edwards Lifesciences measures blood sugar by Glucose Oxidase Sensing Technology through in-blood measurement. Blood is automatically drawn and analyzed every 5 minutes from a peripheral venous catheter, with real time graphical display. Blood is then returned to the patient and the system automatically self-calibrates. The GlucoClear CGM is designed to be highly accurate. In a recent study performed in critically ill patients, it was shown to comply with the required standards of quality.
The main research question addressed by the present study is: "To which extent a CGM-guided strategy improve the quality of BG control performance"?

Inny: Standard of care
Healthcare providers used the usual intermittent method to adapt insulin therapy; the blood glucose values measured by the intravascular continuous monitoring were not displayed but recorded.
Usual care involves the adjustment of insulin infusion based on BG values measured with a blood gas analyser 4-6 times per day.
