The challenge of integrating a diagnosis of malnutrition in the practical application of nutrition care in the intensive care unit.

Evidence of poor nutrition status in a patient present on admission to the intensive care unit is associated with worse clinical outcomes than that for a well-nourished patient who becomes critically ill. Diagnosing malnutrition in this setting is fraught with difficulty, though, because elements of nutrition history are hard to obtain, the interpretation of anthropometric parameters is influenced by the disease process and interventions of critical care and the subjectivity of traditional assessment tools lacks precision. Determining the severity of disease drives the initial management and sets priorities in the derivation of the nutrition plan, focusing on strategies that promote survival.

Exploring the impact of arginine-supplemented immunonutrition on length of stay in the intensive care unit: A retrospective cross-sectional analysis.

Background: Arginine-supplemented enteral immunonutrition has been designed to optimize outcomes in critical care patients. Existing formulas may be isocaloric and isoproteic, yet differ in L-arginine content, energy distribution, and in source and amount of many other specialized ingredients. The individual contributions of each may be difficult to pinpoint; however, all cumulate in the body's response to illness and injury.

Characteristics and feeding intolerance in critically ill adult patients receiving peptide-based enteral nutrition: A retrospective cross-sectional study.

Background & Aims: Patients who experience gastrointestinal (GI) intolerance and hyperglycemia (or glucose intolerance) may not achieve appropriate caloric requirements and experience poor outcomes. The aim was to examine patient characteristics, disease severity, and enteral nutrition (EN) formula use in relation to feeding intolerance and healthcare resource utilization.

Methods: A retrospective, cross-sectional design using real-world data from PINC AI™ Healthcare Database, 2015-2019 was used.

The importance of providing dietary fiber in medical and surgical critical care.

The early provision of soluble/insoluble fiber to the patient who is critically ill has been controversial in the past. Especially in the setting of hemodynamic instability, dysmotility, or impaired gastrointestinal transit, fear of inspissation of formula with precipitation of nonocclusive mesenteric ischemia (NOMI)/nonocclusive bowel necrosis (NOBN) limited its utilization by medical and surgical intensivists. The incidence of NOMI/NOBN has been estimated at 0.

Healthcare Resource Utilization and Cost Comparisons of High-Protein Enteral Nutrition Formulas Used in Critically Ill Patients.

High-protein enteral nutrition is advised for patients who are critically ill. Options include immunonutrition formulas of various compositions and standard high-protein formulas (StdHP). Additional research is needed on the health economic value of immunonutrition in a broad cohort of severely ill hospitalized patients.
