Background, Malnutrition, and Catabolism of Critical Illness
For most clinicians, nutritional issues are often secondary in terms of acuity or urgency compared with problems affecting the cardiovascular or respiratory systems, leading to the insidious nature of malnutrition and catabolism. fte important contribution of nutrition and metabolism to out- comes has been recognized only more recently by many ICU providers.
Assessment of Malnutrition and Energy Requirements Regardless of the high prevalence of malnutrition and catabolism in the surgical ICU and years of research focusing on this problem, there is no uniform assessment method, laboratory value, or metric to identify the patients at greatest risk for nutrition-related poor outcomes.
In the past, weight loss of a certain percentage of body weight coupled with physical examination findings in the setting of decreased caloric intake defined malnutrition.
Although weight loss of greater than 10% to 15% of body weight before ICU admission has been shown to be associated with increased mortality in surgical patients, this is a very crude assessment of malnutrition.
