The Effect of Applying Modified NUTRIC Scoring System to Evaluate the Nutrition Risk and Giving Different Types of Nutritional Support on Clinical Outcomes in Critically Ill Patients

Malnutrition is very common in critically ill patients. It is quite important to evaluate nutritional status precisely. Heyland et al firstly reported NUTRIC score including age, APACHE II score, SOFA score, number of commorbidities, days from hospital to ICU admission and IL-6. Because the IL-6 is not routinely checked at ICU. A modified NUTRIC score without IL-6 is more practical. Previous studies showed lower in-hospital mortality in higher nutritional risk patients with higher caloric intake compared with lower caloric intake. However, there is still controversial regarding the in-hospital mortality between full caloric feeding and permissive underfeeding in critically ill patients. Herein the investigators conduct a study to investigate what kinds of nutritional supplements will decrease in-hospital mortality in different nutritional risk patients.
