Australian Committee on Antimicrobial Susceptibility Testing (AUSCAST)

Antimicrobial susceptibility test (AST) results are among the most important results issued by the microbiology laboratory as they routinely guide critical treatment decisions. With increasing rates of antimicrobial resistance, new antimicrobial agents, and changes to breakpoints by EUCAST and CLSI, a national AST committee has an important role to provide a resource for laboratories to seek assistance and provide feedback to.

Originally established in mid-2011 to provide expert advice and further the cause of skill development in the area of antimicrobial susceptibility testing, the Australian Committee on Antimicrobial Susceptibility Testing, AUSCAST (previously known as the ASA National EUCAST AST Committee, AusNAC) is the affiliated national committee within the European Committee on Antimicrobial Susceptibility Testing (EUCAST) network (http://www.eucast.org/organization/nac/). In 2024, ASA has endorsed a new committee structure to support Australian laboratories that perform and report AST results, which is inclusive of different breakpoint references (e.g., EUCAST and CLSI). This committee has adopted the name ‘AUSCAST’.

In order to increase the reach and impact of the committee, the upgrade and rebrand the committee now includes a formal structure with an Executive (chair, scientific secretary, education officer), 8 general members (applications received from the ASA membership), and 4 co-opted members (representing New Zealand, AGAR, APAS and Pharmacy). Positions will be held for 2-year terms with a chance to renew twice more.

AUSCAST will undertake a number of key roles throughout the year, including:

  • Organising the AST workshop at the ASA annual meeting
  • Act as the central point-of-contact to support diagnostic laboratories with AST questions
  • Provide educational content in basic and advanced aspects of AST, including regular articles in the ASA Breakpoint quarterly newsletter

Furthermore, AUSCAST will endeavour to provide additional national services, including:

  • Developing national AST resources including guidelines, advice documents, and a library of AST comments for final AST reports
  • Coordinating multi-laboratory projects and studies
  • Provide input and formal responses for general consultation documents sent out by EUCAST
  • Disseminating alerts and warnings from EUCAST and CLSI

AUSCAST will also discuss topics and questions asked of the committee from laboratories, and, if possible, provide feedback, guidance or commentary to be available for all.

The Society conducts national annual scientific meetings and has hosted the Asian Pacific Conference on Clinical Microbiology and Infectious Diseases and the International Symposium on Staphylococci and Staphylococcal Infection. It actively supports research into antimicrobials and antimicrobial resistance.
