Antimicrobial consumption database (ESAC-Net)


The ESAC-Net interactive database provides European reference data on antimicrobial consumption, both in the community and the hospital sector. The reports of the database are provided through the European Surveillance System (TESSy). The Anatomical Therapeutic Chemical (ATC) classification system is used for the allocation of antimicrobials in groups. Data are presented up to the fourth level of this classification.

Antibiotic consumption is expressed as the number of Defined Daily Doses (DDDs) per 1000 inhabitants per day and the latest ATC/DDD index is applied to consumption data in all years. Please note that in 2019 major alterations have been made in DDDs for some antibiotics thus the data displayed in the interactive database differ from the data in historical annual epidemiological reports.

How representative are the data?

The data have been collected at the national level under the responsibility of each participating country. Each country provided antimicrobial consumption data for the community (primary care sector) and the hospital sector, or for both sectors together (total care). Total care data are reported as community data which has an impact on the presented results.
Sources of data used for reporting, either sales data or reimbursement data, have also an impact on the presented results. Footnotes are provided in the different reports to avoid misinterpretation of the reported consumption data.
For conclusions and interpretation of results presented through the ESAC-Net interactive database, please refer to the Annual reports.
