- 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
- Purpose: There have been no clinical studies on the characteristics of parenteral nutrition (PN) for adult cancer inpatients in South Korea. The published evidence describing modern PN practices in these patients is also extremely limited. Therefore in this retrospective multicenter cross-sectional study, we aimed to investigate the PN support practice in hospitalized adult cancer patients.
Methods: The study included adult cancer patients hospitalized in nine hospitals in South Korea and received PN, during the period from August 1st, 2017 to October 30th, 2017. We evaluated the relevant hospital-based PN practices in this group.
Results: Among the 11,580 inpatient admissions during this period, 759 cancer patients received PN (6.6%). The majority of enrolled patients (97.2%) used commercially available PN and 71.2% of these used peripheral PN formulations. The average in-hospital PN duration was 16.1±19.9 days. Patients received only 65.4±25.4% calories of the recommended target calories. The in-hospital mortality of enrolled patients was 26.1%.
Conclusion: We conclude that commercial PN is the most common form of PN administered to hospitalized adult cancer patients and the overall in-hospital mortality in the patients using PN is higher in South Korea compared to other countries.
