Abstract: Objective: To construct the information chain management mode of large-scale equipment in operating room. Methods: In this study, we analyzed and controlled the key nodes analyzed and controlled by the chain management process of large-scale instruments and equipment in operating room, and the information nurses developed the information platform for the management of large-scale instruments and equipment. Results: The related indexes of equipment management in the department showed that the average time required for instrument and equipment registration, the time of monthly statistical analysis was greatly shortened, the qualified rate of registration was raised to 98.0%, and the cost accounting was saved by 2220 yuan per year. From five aspects of perceived usefulness, perceived ease of use, attitude tendency, behavioral intention and application behavior, nursing staff held positive views, and the correlation degree between the path coefficients of each structure was high and significant. The cross-departmental related indexes showed that the time of equipment use status query time, equipment basic information query time and maintenance personnel arrival time were greatly shortened, and the difference between the two groups was statistically significant (P<0.05). Conclusion: Focusing on user experience in R & D process can promote the positive development of the system, establish a multi-system information transmission way to achieve multi-level information chain management, and give full play to the positive role of information nurses in R & D process, which is undoubtedly a new mode of information development under the condition of limited existing resources.
