Objective To construct an"four-dimensional"Internal Medicine Nursing intelligent service system based on a knowledge graph with the continuous update and development of the internet plus education,and to con-duct a usability pre-test.Methods From March 2023 to February 2024.Based on constructivism learning theory,teaching system design model and knowledge graph construction method,a"four-dimensional"Internal Medicine Nursing intelligent service system of Internal Medicine Nursing based on knowledge graph was constructed,that is,"curriculum objective layer+basic knowledge layer+problem system layer+teaching resource layer".Using the Health Information Technology Usability Assessment Scale,the usability pretest of the"four-dimensional"In-ternal Medicine Nursing intelligent service system based on knowledge graph was carried out.Results The"eight-step"construction method based on knowledge graph completed the construction of the intelligent service system of Internal Medicine Nursing,which mainly included blood system diseases,endocrine and metabolic diseases,rheu-matic diseases,nervous system diseases,respiratory system diseases,circulatory system diseases,digestive system diseases and urinary system diseases.The average scores of the four dimensions of quality of work life,perceived usefulness,perceived ease of use and user control in the usability pre-test were(4.57±0.46)points,(4.48±0.44)points,(4.29±0.62)points,(4.16±0.62)points,respectively.Conclusion The"four-dimensional"intelligent serv-ice system of Internal Medicine Nursing based on knowledge graph is scientific and usable,and can provide online ed-ucational learning tools and methodological reference for nursing educators to construct medical knowledge graph.
