Objective To systematically retrieve and integrate the best evidence of enteral and parenteral nutrition support in adult patients with severe burns. Methods 2 nursing master students who had studied evidence-based nursing systematically searched the clinical decisions，recommended practices，guidelines，expert consensuses，systematic reviews，evidence summaries and other evidences on enteral and parenteral nutrition support for adult patients with severe burns in domestic and foreign guideline networks，relevant institutional websites and databases. The retrieval time was from the establishment of the databases to April 2023. 2 researchers who had obtained master’s degrees and undergone systematic evidence-based training in Fudan University used the appraisal of guidelines for research and evaluation Ⅱ and JBI critical appraisal tools to evaluate the methodological quality，and extracted and summarized the evidence according to the theme. Results A total of 28 articles were included，including 1 clinical decision，9 guidelines，3 expert consensuses，9 systematic reviews，and 6 evidence summaries. A total of 20 pieces of evidence were summarized from 6 aspects：nutritional risk screening and assessment，energy requirement calculation，timing and route of nutritional support，nutrient intake，nutritional support monitoring and effect evaluation. Conclusion The best evidence of enteral and parenteral nutrition support for adult patients with severe burns summarized in this study is more comprehensive and scientific. It is suggested that in clinical application，targeted screening should be carried out according to the promotion and hindering factors of evidence，so as to scientifically carry out nutritional support for adult patients with severe burns.
