A practical guide for enteral nutrition from the Korean Society for Parenteral and Enteral Nutrition: Part III. preparation of enteral nutrition formulas: In Seok Lee, Ye Rim Chang, Bo-Eun Kim, Youn Soo Cho, Sung-Sik Han, Eunjung Kim, Hyunjung Kim, Jae Hak Kim, Jeong Wook Kim, Sung Shin Kim, Eunhee Kong, Ja Kyung Min, Chi-Min Park, Jeongyun Park, Seungwan Ryu, Kyung Won Seo, Jung Mi Song, Minji Seok, Eun-Mi Seol, Jinhee Yoon, Jeong-Meen Seo, for the KSPEN Enteral Nutrition Committee; Ann Clin Nutr Metab 2026;18(1):3-9. Published online March 30, 2026; DOI: https://doi.org/10.15747/ACNM.26.0046

Abstract PDF: Purpose
This guideline was developed to provide evidence-based recommendations for the safe preparation and handling of enteral nutrition (EN) formulas in order to improve patient safety and promote standardized clinical practice in Korea.
Methods
The key questions addressed the selection of open versus closed feeding systems, the safe preparation and handling of EN formulas, precautions related to blenderized tube feeding (BTF), and essential labeling requirements. Recommendations were drafted and refined through multidisciplinary expert consensus under the auspices of the Korean Society for Parenteral and Enteral Nutrition (KSPEN).
Results
The choice of feeding system should be determined according to the patient’s condition, risk of infection, and anticipated duration of feeding. Closed feeding systems are recommended because they reduce contamination risk and nursing workload, whereas open feeding systems require strict adherence to aseptic technique. For open or reconstituted EN formulas, hang time at room temperature should not exceed 4 hours, whereas closed feeding systems should follow the manufacturer’s recommended hang time. For BTF, administration time should be limited to 2 hours to minimize bacterial growth, and their use is contraindicated in medically unstable or immunocompromised patients. Accurate labeling, including patient identifiers, formula information, administration route, and hang time, is essential to prevent administration errors.
Conclusion
These guidelines provide a practical framework for the safe preparation and management of EN formulas. Adherence to standardized preparation protocols, including appropriate feeding system selection and strict hygiene practices, is essential for reducing complications and improving the safety of EN therapy.

A practical guide for enteral nutrition from the Korean Society for Parenteral and Enteral Nutrition: Part II. selection and initiation of enteral feeding routes: Ja Kyung Min, Ye Rim Chang, Bo-Eun Kim, In Seok Lee, Jung Mi Song, Hyunjung Kim, Jae Hak Kim, Kyung Won Seo, Sung Shin Kim, Chi-Min Park, Jeongyun Park, Eunjung Kim, Eunmi Sul, Sung-Sik Han, Jeong Wook Kim, Seungwan Ryu, Minji Seok, Jinhee Yoon, Eunhee Kong, Youn Soo Cho, Jeong Meen Seo, for KSPEN Enteral Nutrition Committee; Ann Clin Nutr Metab 2025;17(3):165-171. Published online December 1, 2025; DOI: https://doi.org/10.15747/ACNM.25.0037

Abstract PDF: Purpose
We developed evidence-based recommendations for selecting and initiating the enteral nutrition (EN) delivery route in adult and pediatric patients to improve safety and standardize practice in Korea.
Methods
Key questions covered feeding tube selection, methods to verify tube placement, confirmation in pediatric patients, and timing of EN following percutaneous endoscopic gastrostomy (PEG). Recommendations were drafted and refined through multidisciplinary expert consensus under the Korean Society for Parenteral and Enteral Nutrition (KSPEN).
Results
Feeding tube selection should be based on gastrointestinal anatomy, function, and expected EN duration. Short-term feeding is recommended with nasogastric or orogastric tubes, whereas long-term feeding should use percutaneous or surgical routes such as PEG. Tube position must always be verified before use, preferably with radiography or pH testing; auscultation alone is unreliable and should not be used. In pediatric patients, radiographic confirmation remains the gold standard, although pH testing and insertion-length assessment may be considered when imaging is not feasible. After PEG, EN can be initiated safely within 4 hours in both adults and children without increasing complications if trained staff monitor for leakage or infection.
Conclusion
This guideline offers a structured framework for safe and timely EN tailored to patient characteristics. Early verification and multidisciplinary collaboration help reduce complication, improving outcomes of EN therapy.

A practical guide for enteral nutrition from the Korean Society for Parenteral and Enteral Nutrition: Part I. prescribing enteral nutrition orders: Ye Rim Chang, Bo-Eun Kim, In Seok Lee, Youn Soo Cho, Sung-Sik Han, Eunjung Kim, Hyunjung Kim, Jae Hak Kim, Jeong Wook Kim, Sung Shin Kim, Eunhee Kong, Ja Kyung Min, Chi-Min Park, Jeongyun Park, Seungwan Ryu, Kyung Won Seo, Jung Mi Song, Minji Seok, Eun-Mi Seol, Jinhee Yoon, Jeong Meen Seo, for KSPEN Enteral Nutrition Committee; Ann Clin Nutr Metab 2025;17(1):3-8. Published online April 1, 2025; DOI: https://doi.org/10.15747/ACNM.25.0002

Purpose
This study aimed to develop a comprehensive practical guide for enteral nutrition (EN) designed to enhance patient safety and reduce complications in Korea. Under the leadership of the Korean Society for Parenteral and Enteral Nutrition (KSPEN), the initiative sought to standardize EN procedures, improve decision-making, and promote effective multidisciplinary communication.
Methods
The KSPEN EN committee identified key questions related to EN practices and organized them into seven sections such as prescribing, delivery route selection, formula preparation, administration, and quality management. Twenty-one experts, selected based on their expertise, conducted a thorough literature review to formulate evidence-based recommendations. Drafts underwent peer review both within and across disciplines, with final revisions completed by the KSPEN Guideline Committee. The guide, which will be published in three installments, addresses critical elements of EN therapy and safety protocols.
Results
The practical guide recommends that EN orders include detailed elements and advocates the use of electronic medical records for communication. Standardized prescription forms and supplementary safety measures are outlined. Review frequency is adjusted according to patient condition—daily for critically ill or unstable patients and as dictated by institutional protocols for stable patients. Evidence indicates that adherence to these protocols reduces mortality, complications, and prescription errors.
Conclusion
The KSPEN practical guide offers a robust framework for the safe delivery of EN tailored to Korea’s healthcare context. It emphasizes standardized protocols and interdisciplinary collaboration to improve nutritional outcomes, patient safety, and operational efficiency. Rigorous implementation and monitoring of adherence are critical for its success.

Nutrition Support Nurse: Roles and Tasks: Jeong Yun Park, Jung Mi Song, Ja Kyung Min; J Clin Nutr 2020;12(1):2-6. Published online June 30, 2020; DOI: https://doi.org/10.15747/jcn.2020.12.1.2

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.

Economic Evaluation of Home Total Parenteral Nutrition: Ja Kyung Min; J Clin Nutr 2016;8(1):19-23. Published online April 30, 2016; DOI: https://doi.org/10.15747/jcn.2016.8.1.19

Abstract PDF: The restricted resources on healthcare highlights the importance of clinical and cost effectiveness. The social and economic costs of chronic diseases are increasing. Home total parenteral nutrition (home TPN) for the patients with intestinal failure is a life-sustaining therapy until intestinal transplantation. An economic evaluation of home TPN has not been conducted in Korea. Three types of economic evaluations for home TPN are cost benefit analysis, cost effectiveness analysis, and cost utility analysis. Korea’s medical market is competitive due to the limited health care resources. A health care delivery system from hospital to home needs to be established under the supervision of professional Nutrition Support Team staff including the systematic policies and social recognition.
