Results submitted to the International Council of Nurses (ICN)
Presented at an international conference in Finland
Shared smart AMR prevention and control practices
Promoted international exchange in infection control
Enhanced efficiency in hospital-wide AMR surveillance and cluster management by shortening data compilation time, reducing duplicated work and manpower burden, improving cross-unit collaboration consistency and replicability, and promoting smart infection control and healthcare sustainability.
Through the first-in-practice implementation of automated same-unit event tagging, automated shared-contact comparison, and automated generation of suspected transmission chain visualizations, the system standardizes tracking workflows, supports early intervention, reduces transmission risk, and strengthens healthcare quality and patient safety.
