Mechanisms of catheter-associated urinary tract infection, based on a prospective study of 1,497 newly catheterized patients who had 235 new-onset infections (16)
| Organisms causing CAUTIa | ||||
|---|---|---|---|---|
| Mechanism of CAUTI |
Gram-positive
cocci (n=44) |
Yeasts (n=34) |
Gram-negative
bacilli (n=37) |
Overall (n=115) |
| Extraluminal | 79% | 69% | 54% | 66% |
| Intraluminal | 21% | 31% | 46% | 34% |
aPercentages refer to organisms in which the mechanism of infection could be determined. For comparison of gram-positive cocci and yeasts vs. gram-negative bacilli, p = 0.007.
CAUTI = catheter-associated urinary tract infection.
