Nutrition support practitioners have long understood the negative impact of malnutrition on patient outcomes. Smaller studies have reported conflicting data about the magnitude and impact of malnutrition and patient outcomes. This is particularly true in studies focusing on obese patients. This session will provide an overview of novel outcome studies obtained from large administrative datasets indicating that preexisting malnutrition, identified through a comprehensive nutrition assessment conducted by a registered dietitian, contributes to poor outcomes in critically ill patients. The impact of protein-calorie malnutrition, obesity, and vitamin D deficiency on bloodstream infection, sepsis, acute kidney injury, and mortality will be presented. Potential mechanisms will be discussed and intervention strategies will be explored.
Learning Objectives:
Identify three negative outcomes associated with preexisting malnutrition in critically ill patients
Explain why obesity is not protective in all critically ill patients
Identify two interventions to improve delivery of nutrition support to critically ill patients
