The 15 most frequently reported pathogens from hospital wards are shown, along with their distribution and rank within the other location types. Some rankings within the other location types are not shown: hospital ICUs #15 (Yeast, not otherwise specified); hospital oncology units #13 (Rothia mucilaginosa), #14 (Bacteroides spp); LTACHs #15 (Proteus spp).
Supplemental tables are available in the 2015–2017 Adult Antimicrobial Resistance Report Online Supplement that show pathogen rankings separately for mucosal barrier injury laboratory-confirmed bloodstream infection (MBI-LCBI) and non–MBI-LCBIs (https://www.cdc.gov/nhsn/datastat/index.html).
Location types are mutually exclusive. “Hospital wards” includes step-down units, mixed acuity units, and specialty care areas.
When analyzed on the genus level, Candida and Enterococcus resulted in the following rankings: Candida: hospital wards (#1), hospital ICUs (#1), hospital oncology units (#7), LTACHs (#2); Enterococcus: hospital wards (#3), hospital ICUs (#2), hospital oncology units (#1), LTACHs (#1).
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. The group ‘Other Candida spp’ combines Candida identified to the species level, excluding C. albicans and C. glabrata, and Candida for which the species was not reported.
Candida parapsilosis was reported with the following frequencies: hospital wards (846); hospital ICUs (810); hospital oncology units (122); LTACHs (446).
