Analysis and Presentation of Cumulative Antimicrobial Susceptibility Data (Antibiograms): Substantial Variability Across Medical Centers in the United States

Abstract

We found substantial variability in approaches to constructing antibiograms at 65 United States medical centers. Laboratories in teaching hospitals and those with more personnel were significantly more likely to offer sophisticated antibiogram approaches, including the compiling of unit-specific susceptibility data and the reporting of temporal trends in susceptibility data.
