The objective is to increase caloric adequacy in patients who survived critical illness and are admitted to the ward by the use of a pro-active inclusive nutritional strategy including supplemental parenteral and/or enteral nutrition and/or oral nutritional supplements guided by indirect calorimetry.

This enables the investigators to address, within a clinical/scientific context, a recently demonstrated but until now relatively neglected 'dark side' of patient care at UZ Brussel, comparable to limited global evidence : iatrogenic malnutrition of ICU survivors. The use of a newly developed clinical pathway and nutrition strategy (oral, enteral and parenteral) led by a single SPoC (Single Point of Contact) for patients surviving intensive care will have a clear objective: to address the nutritional deficit in all patients.
