92 Chapter 5 ABSTRACT Background. Malnutrition is a serious problem in critically ill patients. Identifying patients who are at risk of malnutrition is important in order to nd ways of improving the quality of care. This study might form the basis to develop strategies to support intensive care unit (ICU) sta to provide adequate enteral nutrition (EN) and to minimize the risks for malnutrition in critically ill patients. Methods. This retrospective observational study was conducted in a university hospital in Amsterdam, the Netherlands. Patients admitted to the ICU from January 2012 to December 2014 were included. Ideal calorie intake is calculated as 25 Kcal/kg/day. Ideal protein intake as 1.2 to 1.5 g/kg/day. Multilinear regression was used to describe the factors of success of EN intake. Results. Overall, patients received 65% of the ideal protein intake and 66% of the ideal caloric intake. The daily success of EN intake has a median of >90%. The multilinear analyses showed that the nasoduodenal-, nasojejunal- and percutaneous endoscopic gastrostomy (PEG) feeding tubes achieved a signi cant better intake than nasogastric tubes. Conclusion. The delivery of EN in critically ill patients was moderate to high in the majorityof thepatients. However, a substantial part of theENdeliverywas still suboptimal during admission and needs to be improved. This implies a strong argument to support ICU sta in the adequate delivery of EN. This could be facilitated by a nutritional care bundle to support guideline uptake and thereby improve the delivery of EN.
