M23: Development of In Vitro Susceptibility Testing Criteria and Quality Control Parameters, 6th Edition

CLSI requests nominations for volunteers to serve as members and advisors on a working group for a document revision.

Description

CLSI document M23 will provide direction for determining breakpoints and quality control (QC) parameters for antimicrobial agents that have a direct action on microorganisms. The intended audience includes sponsors (eg, antimicrobial agent manufacturers) planning to submit data to establish or revise QC ranges and susceptibility testing breakpoints and interpretive categories for inclusion in CLSI susceptibility testing documents. Anticipated revisions include but are not limited to:

  • Clarifying the use of M23 by the Subcommittees on Antifungal Susceptibility Tests and Veterinary Antimicrobial Susceptibility Testing
  • Harmonizing disk content with the European Committee on Antimicrobial Susceptibility Testing (EUCAST)
  • Clarifying the use of epidemiological cutoff values
  • Including an intermediate breakpoint for disk diffusion when one does not exist for broth dilution
  • Clarifying the requirements for testing media for disk diffusion
  • Providing guidance on acceptable error rates between disk diffusion and broth dilution results for antimicrobial agents designed to treat less-susceptible organisms

This group is looking for volunteers with:

  • Understanding of basic microbiology, pharmacokinetics-pharmacodynamics, and the interpretation of antimicrobial agent clinical studies
  • Understanding of the current process used by CLSI to determine interpretive criteria/breakpoints
