This paper aims to conduct a comprehensive review of the relevant literature on the application of GLIM standard in surgical inpatients understand the actual application status and effect of GLIM standard in surgical patients promote the continuous improvement and optimization of the standard and provide reference for the subsequent application and verification of GLIM standard. According to the Australian Joanna Briggs Institute scoping Review guidelines Computer searches were conducted on PubMed CINAHL Scopus Embase The Cochrane Library Web of Science CNKI Wanfang Data Knowledge Service Platform and Chinese biomedical literature database etc. and the extracted data of the included literatures were sorted out and analyzed. A total of 34 literatures met the study criteria. Patients undergoing surgery for gastrointestinal tumors during surgery were the key population for GLIM standard application and the more common types of study design were cohort studies and cross - sectional studies. The most commonly used phenotype indicators are involuntary weight loss and low body mass index and the most commonly used etiological type indicators are disease or inflammatory status. GLIM criteria have good clinical applicability in the diagnosis of malnutrition in some surgical inpatients. There is still a need to use the complete GLIM diagnostic criteria for malnutrition in different surgical patient populations and disease Settings in strict accordance with the guidelines to identify and address possible problems or deficiencies in the GLIM criteria and to promote continuous improvement and optimization of the criteria to meet the needs of different contexts.
