Abstract：Objective To evaluate the effect of the monitoring and early warning system for acute flaccid paralysis(AFP)cases in a tertiary general hospital in Beijing,and to provide a reference for similar medical institutions.Methods Taking Beijing Anzhen Hospital,Capital Medical University as an example,the baseline data before optimization were the AFP monitoring and early warning data from January to June 2024,and the outcome data after optimization were the AFP monitoring and early warning data from January to June 2025.The differences in the number of monitoring and early warning pop-ups,disease types,early warning trigger rate and management process of the AFP case monitoring and early warning system before and after optimization were compared.Results After the system optimization,real-time pop-ups could be triggered when clinical doctors included 14 AFP disease keywords such as"nerve,paralysis,spinal cord"in the diagnosed disease types.A total of 113 pop-ups were triggered by clinical doctors from January to June 2025,an increase of 16.49％compared with the same period in 2024,involving an increase in disease types from 2 to 7.The number of visits by patients under 15 years old from January to June 2025 decreased by 22.92％compared with the same period in 2024,and the pop-up early warning trigger rate was 2.97‰,which was significantly higher than 1.96‰ in the same period in 2024(U=2.991,P＜0.01).In addition,the pop-up interface of the functional management department added the functions of recording the cause of early warning trigger,disposal basis and results,and simultaneously added the retrieval function of fuzzy diagnosis fields,supporting real-time retrieval of any diagnosis keywords in all departments of the hospital.Conclusion After the system optimization,the sensitivity of AFP case pop-up trigger is significantly improved,which helps to enhance clinicians' awareness of AFP case identification and reporting;the functional management department can realize permanent traceability of disposal records.The fuzzy diagnosis field retrieval function can not only reduce irrelevant pop-ups for clinicians and lighten their workload,but also improve retrieval efficiency,and provide a flexible keyword retrieval channel for the monitoring of various infectious diseases.
