AMC Tool: the antimicrobial consumption tool
AMC Tool: the antimicrobial consumption tool

AMC Tool is a programme to calculate antimicrobial consumption. It is aimed to replace the old ABC Calc tool.
As its predecessor, AMC Tool computes antimicrobial consumption data provided as numbers of packages into numbers of Defined Daily Doses (DDD) using the ATC/DDD index.

Latest news

  • AMC Tool version 1.4.3 released
    08 October 2014

    The AMC Tool version 1.4.3 has been released.

    This version includes a disclaimer for the use of material developed by the WHO Collaborating Centre for Drug Statistics Methodology, Oslo Norway.

    Minor issues have been solved since the previous version.

New programme:

AMC Tool is a completely new programme, freely available.

New functionalities:

AMC Tool has extended the basic functionalities of ABC Calc in order to provide a better user experience.

AMC Tool includes additional ATC groups and can process consumption data for antibiotics, antimycotics, antifungals and antivirals.

AMC Tool uses two indicators to report antimicrobial consumption:

  • DDD per 1000 inhabitants per day
  • DDD per 100 bed-days

and allows the calculation of consumption data from either healthcare settings or the community.

In addition to manual data entry, AMC Tool can read files provided in a standardised format in order to facilitate the process of data entry.

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

ATC/DDD index:

AMC Tool uses the ATC/DDD index developed by the WHO collaborating centre for drug statistics methodology.

Only a subset of the ATC/DDD index corresponding to antimicrobials is implemented into the programme:

  • A07: Intestinal antiinfectives
  • D01BA: Antifungals for systemic use (dermatologicals)
  • J01: Antibacterials for systemic use
  • J02: Antimycotics for systemic use
  • J04: Antimycobacterials
  • J05: Antivirals for systemic use
  • P01AB: Nitroimidazole derivatives (antiprotozoals)

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