Surveillance of antimicrobial resistance in Europe, 2023 data : executive summary

This executive summary sets out results derived from 2023 antimicrobial resistance (AMR) data, sourced from invasive isolates reported to both the Central Asian and European Surveillance of Antimicrobial Resistance (CAESAR) network and the European Antimicrobial Resistance Surveillance Network (EARS-Net). CAESAR received reports from 15 countries, while EARS-Net amassed data from 30 countries, encompassing the whole of the European Union/European Economic Area (EU / EEA). Although both EARS-Net and CAESAR use compatible methodologies for data gathering and analysis, the information originates from distinct surveillance systems in the various countries. Given that each national surveillance system is shaped by country-specific protocols and practices, it is important to exercise caution when comparing AMR patterns between them
