 Abstract
 PDF Supplementary Material
- Purpose
Nutritional therapy is an essential component of intensive care management. Appropriate nutritional support may reduce infectious and metabolic complications and promote recovery in critically ill patients. However, nutritional practices vary across institutions, and international guidelines may not be directly applicable to clinical practice in Korea. Evidence-based clinical practice guidelines that reflect Korean intensive care unit practice are therefore needed.
Methods
The Korean Society for Parenteral and Enteral Nutrition developed these clinical practice guidelines for nutritional therapy in critically ill adults through a systematic literature review and multidisciplinary expert consensus.
Results
In total, 24 key clinical questions and 59 recommendations were developed. The guidelines address enteral and parenteral nutrition, feeding intolerance, aspiration prevention, energy and protein assessment, immune-modulating nutrition, micronutrient supplementation, refeeding syndrome, and disease-specific nutritional therapy for critically ill adults, including those with acute kidney injury, acute liver failure, acute respiratory distress syndrome, sepsis, trauma, and obesity. The recommendations emphasize individualized nutritional therapy according to hemodynamic status, metabolic phase, organ dysfunction, nutritional risk, and treatment goals.
Conclusion
These guidelines provide practical, evidence-based recommendations for nutritional therapy in critically ill adults and reflect both current international evidence and Korean clinical practice. They may support more standardized and consistent nutritional support in Korean intensive care units.

Abstract
PDF
- Nutrition care is important for patients’ well-being. With legislation for reimbursement for nutrition support team activities from the Korea Ministry of Health and Welfare, this has increased the importance of nurses’ role in nutrition. Nutrition support nurses (NSNs) focus on the optimization of nutritional health and prevention of nutrition-related illness and injury. NSN performs as an advanced practice nurse, a core member of a nutrition support team, an educator or consultant, a policy maker in nutrition care, and a researcher or a member of quality improvement. NSNs should develop their core competency to fulfill their roles in nutrition care and the need to participate in qualified nutrition support education programs. Further, the tasks and duties of NSNs should be specifically identified so that NSNs can fulfill their roles.
