Users enter a short description of the antimicrobial products and the number of consumed packages. AMC Tool calculates the corresponding number of Defined Daily Doses (DDD) from the number of packages.

Internally AMC Tool uses the Anatomical, Therapeutic, Chemical (ATC) classification and the Defined Daily Dose (DDD) metric developed by the WHO collaborating center on drug statistics methodology based in Oslo, Norway.

AMC Tool can manage ATC groups relevant for systemic antimicrobials.

ATC groups included:

  • A07AA: antibiotics as intestinal antiinfectives
  • D01BA: Antifungals for systemic use
  • J01: Antibactericals for systemic use
  • J02: Antimycotics for systemic use
  • J04: Antimycobacterials
  • J05: Antivirals for systemic use
  • P01A: Agents against amoebiasis and other protozoal diseases
  • P01B: Antimalarials

Indicators generated by AMC Tool

  • DDD per 1000 inhabitants per day (for consumption in the community)
  • DDD per 100 bed-days (for consumption in hospitals)

Data entry

  • Manual data entry
  • Import data from a csv file

AMC Tool exports the computed consumption data in DDD in a standardised format ready for further analyses.

Data export

  • Export package data entered manually into a csv file
  • Export DDD data into a csv file at substance level


AMC Tool is the successor of ABC Calc, a simple excel tool created by D. Monnet in the 2000s. AMC Tool was originally developed to circumvent the limitations of ABC Calc and the burden of maintaining the excel file. Between 2011 and 2015, AMC Tool was partly funded by the European Centre for Disease Prevention and Control (ECDC) under the framework contract ECDC/2012/042.

In general, AMC Tool is updated every year to include the latest available ATC/DDD index.
