Abstract: Objective To compare the changes in infectious disease outbreak monitoring and reporting before and after the application of the pre-positioned software for intelligent infectious disease surveillance and early warning in a Grade Ⅲ Level A hospital in Shandong Province, and to analyze its advantages and disadvantages in practical use, so as to provide reference for further optimization of the software. Methods Infectious disease reporting data were extracted from the hospital information system for the year before(January-November 2024)and the year after(January-November 2025)the software application. Staff interviews were conducted to analyze changes in workflow and time consumption from case monitoring to reporting. Results After the application of the pre-positioned software, case detection time was shortened from within 12 hours to within 1 minute, and the time to complete reporting per case was reduced from over 10 minutes to within 3 minutes. The initial underreporting rate decreased from 11.09% to 1.68%(P<0.001), and the accuracy rate of report card completion increased from 91.75% to 98.02%(P<0.001), while no statistically significant difference was observed in the completeness rate(P>0.05). However, the full configuration cost of the software is high, the software cannot yet be used completely independently of the National Notifiable Infectious Diseases Reporting System(NNIDRS), and the requirement for a dedicated network reduces the feasibility of remote work. Conclusion The application of the pre-positioned software can reduce the burden on staff in daily disease monitoring and reporting. It is recommended to increase financial support to lower configuration costs and to add functions such as case revision and deletion, enabling the software to be used independently of the NNIDRS.
