Incidence and Susceptibility of Pathogenic Bacteria Vary between Intensive Care Units within a Single Hospital: Implications for Empiric Antibiotic Strategies

Abstract

Although the microbiologic results of this study should not be extrapolated to other institutions, the principle is of value. There is variability between ICUs in a single large teaching hospital in susceptibility of bacterial pathogens to various antibiotics. This may have implications in the design of empiric antibiotic strategies and the planning of the hospital formulary. Hospital wide or composite ICU antibiograms are inadequate for planning empiric therapy in the ICU.
