The CLSI cefepime breakpoints were revised to include a susceptible-dose-dependent (SDD) category forEnterobacteriaceae , with the intention that higher cefepime doses be used for these isolates. In this study, 1.6% ofEnterobacteriaceae isolates were reported as SDD, withEscherichia coli the most common SDD organism. Cefepime was prescribed in three cases (4.8%); the majority of SDD isolates were treated with a carbapenem.Enterobacteriaceae with cefepime SDD MICs were not commonly treated with cefepime at our institution.
