The World Health Organization (WHO) published its first CAESAR annual report 2014. This report describes the resistance data from five countries in the WHO European Region gathered through the Central Asian and European Surveillance of Antimicrobial Resistance (CASESAR) network. The WHO Collaborating Centre for AMR Epidemiology and Surveillance at the Dutch National Institute for Public Health and the Environment, RIVM coordinates CASESAR data collection and conducted the data analysis and drafted the report in collaboration with partners.

In 2012 the Central Asian and Eastern European Surveillance of Antimicrobial Resistance (CAESAR) network was established to assist countries in setting up or strengthening national AMR surveillance and to contribute to region-wide AMR surveillance. CAESAR is a joint initiative of the World Health Organization Regional Office for Europe, the European Society of Clinical Microbiology and Infectious Diseases and WHO Collaborating Centre for AMR Epidemiology and Surveillance at RIVM. 

CAESAR annual report provides guidance to the reader on how to interpret the surveillance data with caution, taking conditions outside the direct control of the national antimicrobial resistance surveillance system into account, which may reduce the reliability and representativeness of the data. The aim of the annual report is to provide guidance and inspiration to countries that are building or strengthening their national antimicrobial resistance surveillance and to stimulate the sharing of data internationally.
