Analysis and Presentation of Cumulative Antimicrobial Susceptibility Test Data: Approved Guideline M39-AR, 4th Edition

Analysis and Presentation of Cumulative Antimicrobial Susceptibility Test Data: Approved Guideline M39-AR is a specialized reference from the Clinical and Laboratory Standards Institute (CLSI) addressing the recording, organization, analysis, and presentation of cumulative antimicrobial susceptibility test data.

The guideline provides a standardized approach for summarizing antimicrobial susceptibility patterns observed among clinically significant microorganisms. By bringing together cumulative and ongoing susceptibility data, it can support laboratories and healthcare professionals in understanding local antimicrobial resistance patterns and producing meaningful susceptibility summaries.

About the Book

Antimicrobial susceptibility testing generates important information about how microorganisms respond to antimicrobial agents. However, individual test results become considerably more useful when they are systematically collected and analyzed over time.

M39-AR focuses on methods for creating cumulative summaries of susceptibility results and presenting those findings in a practical format. It is intended to help laboratories establish consistent approaches to handling susceptibility data and monitoring susceptibility patterns.

Recording Antimicrobial Susceptibility Data

The guideline describes approaches for recording antimicrobial susceptibility test results from clinically significant microorganisms. Proper organization of these data is essential for producing reliable cumulative summaries and ensuring that susceptibility patterns can be evaluated consistently.

Analysis of Cumulative Data

A major focus of M39-AR is the analysis of accumulated antimicrobial susceptibility results. Examining data collectively can provide a broader picture of susceptibility patterns than individual laboratory reports alone.

The guideline therefore provides a framework for turning routine susceptibility test results into useful cumulative information that can be reviewed and interpreted over time.

Presentation of Susceptibility Patterns

Clear presentation is an important part of antimicrobial susceptibility surveillance. The document addresses methods for summarizing and presenting susceptibility patterns so that the resulting information can be readily understood and used by laboratory and clinical personnel.

These summaries can contribute to a better understanding of antimicrobial susceptibility within the populations and microorganisms represented by the laboratory’s data.

Cumulative and Ongoing Summaries

M39-AR addresses both cumulative and ongoing summaries of antimicrobial susceptibility information. Maintaining these summaries allows laboratories to organize susceptibility data systematically and follow changes in observed patterns over time.

Such information can be particularly valuable when evaluating trends in antimicrobial susceptibility and resistance within a healthcare setting.
