*CLABSI, central line–associated bloodstream infection. Patient median age (range) for those with disseminated infection 56 y (32–73 y), for those with CLABSI 44 y (11–77 y); p = 0.31. Median hospital stay (range) for those with disseminated infection 24 d (8–53 d), for those with CLABSI 5 d (2–18 d); p = 0.01. Median antimicrobial drug treatment duration (range) for those with disseminated infection 50 d (21–105 d), for those with CLABSI 82 d (14–120 d); p = 0.56.
†Species were not determined for 2 isolates.
