The survival and the outcomes of critically ill patients are strongly influenced by insulin-therapy and nutritional support. The GLUCOSAFE 2 pilot study, aims to test the performance and the security of the new GLUCOSAFE 2 software, developed by the model-based medical decision support of Aalborg University (Denmark) and adapted to the clinical needs in the intensive care unit (ICU) of the Geneva University Hospital (HUG). This new device is based on a mathematical model of the glucose-insulin metabolism and attempts to give advices for better glycaemia control and nutritional therapy. The GLUCOSAFE 2 study hypothesizes that the use of the Glucosafe 2 software will allow better glycaemia ("Time-in-target") control and better achievement of nutritional energy and protein targets in comparison to the local protocols.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| GLUCOSAFE 2 | Experimental | Insulin-therapy and nutrition support guided by the GLUCOSAFE 2 software. |
|
| Local protocol control group | Active Comparator | Insulin-therapy and nutrition support guided by the local protocols (electronic or paper version) of the ICU/HUG. |
|
| Historical control group | Other | Retrospective data with standard care before the beginning of the pilot study in order to minimize the "cross-over" effect due to the fact that caregivers are going to have in charge patients in both groups (intervention and control group) at the same time. |
