Barriers and Solutions to Delivery of Intensive Care Unit Nutrition Therapy

Despite recommendations for early enteral nutrition (EN) in critically ill patients, numerous factors contribute to incomplete delivery of EN, including insufficient nutrition risk screening in critically ill patients, underutilization of enteral feeding protocols, fixed rate-based enteral infusion targets with frequent EN interruption, and suboptimal provider practices regarding nutrition support therapy. The purpose of this narrative review is to identify common barriers to optimizing and delivering nutrition in critically ill patients, and suggest strategies and solutions to overcome barriers.
