Purpose Of ReviewTo summarize recent data regarding nutritional assessment and interventions in the ICU.Recent FindingsCurrent methods to assess nutritional risk do not allow identification of ICU patients who may benefit from specific nutritional intervention. Early full energy delivery does not appear to improve outcomes at the population level. Specific nutrient composition of formula has been shown to improve glycemic outcomes in patients with hyperglycemia but patient-centered outcomes are unaffected.SummaryBased on recent studies, full energy feeding early during critical illness has no measurable beneficial effect, and may even be harmful, when applied to entire populations. The mechanisms underlying this are unknown and remain proposed theories. Tools to assess nutritional risk in the ICU that identify patients who will benefit from a specific nutritional intervention are lacking. The optimal composition of feeds, and indications for specific interventions for enteral feeding intolerance remain uncertain.
