Registered dietitian nutritionists (RDNs) are pivotal in managing NST, using their expertise to assess malnutrition risk, evaluate suitable nutrition routes, and lead teams in evidence\u2010based nutrition care. However, not all RDNs operate at an expert level owing to varying education, training, and clinical experiences. A survey to determine expert\u2010level RDN NST practices was created and distributed through the Dietitians in Nutrition Support Dietetic Practice Group of the Academy of Nutrition and Dietetics and the Dietetics Practice Section of the American Society for Parenteral and Enteral Nutrition. The survey gathered data on demographics, practice characteristics, and frequency of and barriers to performing select expert\u2010level practice indicators using the Academy of Nutrition and Dietetics and American Society for Parenteral and Enteral Nutrition: Revised 2021 Standards of Practice and Standards of Professional Performance for RDNs (competent, proficient, and expert) in Nutrition Support. A total of 668 RDNs completed the survey (12.4% response). Findings revealed that RDNs frequently performed nutrition\u2010focused physical examinations (83%) and determined micronutrient supplementation (59%). RDNs performed the following activities less frequently: evaluating body composition using diagnostic results (9%), inserting nasogastric\/nasoenteric tubes (19%), and leading quality\u2010improvement initiatives (30%). Key barriers identified included lack of training\/experience and institutional support, and regulatory constraints. These results underscore the need for enhanced professional development, including training programs and interprofessional collaboration, to promote RDN expert\u2010level NST practice and advance the dietetics profession.<\/jats:p>","DOI":"10.1002\/ncp.11341","type":"journal-article","created":{"date-parts":[[2025,6,27]],"date-time":"2025-06-27T03:14:07Z","timestamp":1750994047000},"page":"291-303","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Advanced nutrition support therapy practices of registered dietitian nutritionists: A survey of the Academy of Nutrition and Dietetics' Dietitians in Nutrition Support Dietetics Practice Group and the American Society for Parenteral and Enteral Nutrition Dietetics Practice Section"],"prefix":"10.1002","volume":"41","author":[{"given":"Susan","family":"Lessar","sequence":"first","affiliation":[{"name":"Valley Health System Winchester VA USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rebecca A.","family":"Brody","sequence":"additional","affiliation":[{"name":"Department of Clinical and Preventive Nutrition Sciences School of Health Professions, Rutgers University Newark NJ USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stephanie","family":"Dobak","sequence":"additional","affiliation":[{"name":"Department of Neurology Jefferson Weinberg ALS Center Philadelphia PA USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sharon","family":"Foley","sequence":"additional","affiliation":[{"name":"Department of Clinical Nutrition, College of Health Sciences Rush University Medical Center Chicago IL USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8345-0303","authenticated-orcid":false,"given":"Ainsley","family":"Malone","sequence":"additional","affiliation":[{"name":"Department of Clinical Practice The American Society for Parenteral and Enteral Nutrition Silver Spring MD USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4821-5196","authenticated-orcid":false,"given":"Sarah J.","family":"Peterson","sequence":"additional","affiliation":[{"name":"Department of Clinical Nutrition, College of Health Sciences Rush University Medical Center Chicago IL USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shelby","family":"Yaceczko","sequence":"additional","affiliation":[{"name":"Vatche &amp; Tamar Manoukian Division of Digestive Diseases UCLA Health Los Angeles CA USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kathleen","family":"Price","sequence":"additional","affiliation":[{"name":"Department of Clinical Practice The American Society for Parenteral and Enteral Nutrition Silver Spring MD USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2025,6,27]]},"reference":[{"key":"e_1_2_9_2_1","unstructured":"Robinson D Walker R Adams SC et al.
