Construction of Nursing Management Protocol for Promoting Tolerance of Enteral Nutrition in Tube-Fed Perioperative Cancer Patients

Purpose: Enteral nutrition tolerance studies are mainly focused on critical care, while perioperative nursing research for cancer patients is relatively scattered. This study aims to develop an evidence-based management protocol for promoting tolerance to perioperative enteral nutrition (tube feeding) for cancer patients in general surgical wards, to provide a practical reference for nursing staff. Methods: The study used evidence-based methods. Domestic and international databases were searched for articles on perioperative enteral nutrition (tube feeding) in surgical oncology patients. An initial draft of a generalizable management protocol for enteral nutrition tolerance was formulated through evidence synthesis and research team discussion. Two rounds of Delphi consultation were subsequently conducted with experts in enteral nutrition. Results: A management protocol for perioperative enteral nutrition tolerance in surgical oncology patients was established. The protocol comprised 5 first-level, 12 second-level, and 28 third-level indicators. The expert authority coefficients (Cr) for the two Delphi rounds were 0.857 and 0.880, respectively. The Kendall's concordance coefficients (W) were 0.215 and 0.257 (both P
