Antimicrobial resistance surveillance in the WHO European Region 2023: 2022 data

Overview

The ninth Central Asian and European Surveillance of Antimicrobial Resistance (CAESAR) report provides a comprehensive analysis of the antimicrobial resistance (AMR) situation across the WHO European Region, incorporating data from 2022. This includes contributions from 17 countries, areas or territories: Armenia, Belarus, Bosnia and Herzegovina, Georgia, Kazakhstan, Kyrgyzstan, Montenegro, North Macedonia, Republic of Moldova, Russian Federation, Serbia, Switzerland, Turkmenistan, Turkiye, Ukraine, United Kingdom and Kosovo[‎1]‎. It also integrates data collected and published by the European Centre for Disease Prevention and Control as part of European Antimicrobial Resistance Surveillance Network (EARS-Net) activities, offering a comprehensive view of the AMR landscape in the Region. This report also includes resistance data from Kyrgyzstan for the first time, as well as information on the status of the overall coordination and surveillance of AMR across the entire WHO European Region, encompassing data from both CAESAR and EARS-Net surveillance networks, results from the CAESAR external quality assessment (EQA) exercise in 2022 and a summary of the nine EQA exercises performed between 2013 and 2022. Furthermore, as in previous editions, a readers’ guide is included that supports cautious interpretation of surveillance data, taking data reliability and representativeness into account. WHO and partners are committed through the CAESAR network and its activities to improve AMR surveillance in the Region, to encourage international sharing of data and to guide countries, areas or territories that are building and improving AMR surveillance.
