Countries of the Region Conduct Point Prevalence Surveys on the Use of Antimicrobials at the Hospital Level

Estudios de prevalencia puntual de uso de antimicrobianos

Washington, DC, 19 August 2022 (PAHO) - Chile, Mexico, and Peru are making progress with point prevalence surveys  (PPSs) on antimicrobial use in hospitals, with the support of the Pan American Health Organization (PAHO). PPSs are useful to understand different aspects of medicine prescription patterns for hospitalized patients. 

In Mexico, 12 hospitals conducted PPSs for the year 2022 and presented preliminary results at the national and hospital levels. Self-assessment surveys are currently being conducted with a tool, developed by experts from the Region, to evaluate Antimicrobial Stewardship (AMS) programs of antimicrobials at the hospital level. 

In Peru, eight hospitals participated in the PPS for 2022, and are analyzing the data obtained, both at the country level and from each hospital. Likewise, Chile is in the process of preparing PPSs for 2022 in 10 hospitals in the country. 

This initiative is part of the project "Working together to fight antimicrobial resistance", implemented with support from the European Union, in collaboration with the Food and Agriculture Organization of the United Nations (FAO) and the World Organization for Animal Health (OIE).


Pan American Health Organization (PAHO) participated in the development of two publications in scientific journals that reflect countries' efforts to contain AMR through the rational use of antimicrobials.
