Table 2.

Frequency of Adult Healthcare-Associated Infection (HAI) Events and Pathogens, by HAI Type, 2015–2017

HAI Type	No. (%) HAI Events (n = 311,897)	No. (%) Pathogens (n = 356,633)^a
SSI^b	132,258 (42.4)	154,133 (43.2)
CAUTI	92,715 (29.7)	103,260 (29.0)
CLABSI	78,896 (25.3)	89,203 (25.0)
PVAP^b,c	8,028 (2.6)	10,037 (2.8)

Note. SSI, surgical site infection; CAUTI, catheter-associated urinary tract infection; CLABSI, central line-associated bloodstream infection; PVAP, possible ventilator-associated pneumonia.

Up to 3 pathogens can be reported for each HAI.

SSIs and PVAPs can be reported to the NHSN without an associated pathogen. In total, 27,237 (20.6%) SSIs and 43 (0.5%) PVAPs were reported to the NHSN in 2015–2017 without a pathogen.

PVAP is the only type of ventilator-associated event (VAE) for which a pathogen can be reported.
