Abstract:

Objective To search，select，evaluate and summarize the best evidence of perioperative oral nutritional supplement management in patients with gastric cancer，so as to provide references for the formulation of standardized oral nutritional supplement management program in clinical practice. Methods Guidelines，evidence summaries，systematic reviews，expert consensuses and group standards were systematically and completely retrieved from NGC，NICE，SIGN and other websites，as well as Cochrane Library，JBI and other databases. The retrieve time limit was from the database construction to March，2024. Totally 2 researchers trained in evidence-based nursing independently evaluated the quality of the literature，extracted the evidence，and classified the evidence level. Results A total of 21 articles were involved，including 4 guidelines，6 evidence summaries，5 expert consensuses and 6 systematic reviews. 28 pieces of best evidence on 6 topics were summarized，including the establishment of multidisciplinary teams，health education，type selection and target requirement of oral nutritional supplement，preoperative oral nutritional supplement management，postoperative oral nutritional supplement management，and discharge oral nutritional supplement guidance.
