Methods We systematically searched National Guideline Clearinghouse（NGC），Guidelines International Network（GIN），Scottish Intercollegiate Guidelines Network（SIGN），Joanna Briggs Institute（JBI），Cochrane Library，PubMed，UP To Date，Web of Science，Embase，CNKI，Wanfang Database，medlive for all evidence of swallowing function training in head and neck cancer patients undergoing radiotherapy，including clinical recommended practice，guidelines，expert consensuses，systematic reviews and randomized controlled trials.The retrieval period was from the inception of databases to August 2022. Results A total of 20 articles，including 1 clinical recommended practice，2 guidelines，5 expert consensuses，7 systematic reviews，and 5 randomized controlled trials. Through the evidence extraction and integration of the included literature，27 pieces of best evidence were finally summarized from the following 8 aspects，namely training purpose，training subject，training time，preparation before training，training scheme，radiotherapy suggestions，quality control and effect evaluation. Conclusion 27 pieces of best evidence were obtained based on the evidence summary method. In the process of nursing practice，nurses should select evidence in combination with specific clinical situations and patient needs，and relevant evidence should be updated in a timely manner.
