Predictors of Mortality From Community-Onset Bloodstream Infections Due to Extended-Spectrum β-Lactamase-Producing Escherichia coli and Klebsiella pneumoniae

In a cohort study of 36 patients with community-onset extended-spectrum β-lactamase (ESBL)–producing Escherichia coli or Klebsiella pneumoniae bloodstream infections, we found that predictors of mortality were community-onset infection with ESBL-producing K. pneumoniae pathogens (P = .02) and failure to receive an initial empirical regimen that included either β-lactam and β-lactamase–inhibitors or a carbapenem (P = .04).
