Note. ICUs, intensive care units; LTACHs, long-term acute-care hospitals; IRFs, inpatient rehabilitation facilities; Selected Klebsiella spp, K. oxytoca and K. pneumoniae.
The 15 most frequently reported pathogens from hospital wards and ICUs are shown, along with their distribution and rank within the other location types. Some rankings within the other location types are not shown: hospital oncology units #14 (Stenotrophomonas maltophilia); IRFs #15 (Pseudomonas, not otherwise specified).
Location types are mutually exclusive. “Hospital wards” includes step-down units, mixed acuity units, and specialty care areas.
When analyzed on the genus level, Enterococcus resulted in the following rankings: hospital wards and ICUs (#2), hospital oncology units (#2), LTACHs (#4), IRFs (#4).
The group ‘Other Enterococcus spp’ combines enterococci identified to the species level, excluding E. faecium and E. faecalis, and enterococci for which the species was not reported.
