Healthcare-associated bloodstream infections in critically ill patients: descriptive cross-sectional database study evaluating concordance with clinical site isolates

Annals of Intensive Care

Table 4 Attributed sources of secondary ICU acquired bloodstream infections

Source of blood culture isolate	Concordant isolaten(%)	Discordant isolatesn(%)
Pulmonary (BAL or sputum)	50(53.2)	50(70.4)
Renal/urinary tract	22(23.4)	25(35.2)
Skin and soft tissue	8(8.5)	11(15.5)
Other (aortic valve graft, joint aspirate, limb tissue)	8(8.5)	10(14.1)
Intra-abdominal (fluid or surgical swab)	10(10.6)	6(8.5)
Surgical wound site	3(3.2)	5(7.0)

Note: Isolates have been attributed to multiple sources where concordant cultures exist for more than one organ system within the 48-h window before and after the blood culture was taken. Denominator for calculating proportions were the total number of concordant isolates (n =94) and discordant isolates (n =71). BAL, bronchoalveolar lavage.
