Abstract

Data related to risk factors for catheter-acquired bacteriuria were collected prospectively on 112 patients consecutively catheterized for >24 hours at the Hadassah University Hospital. Logistic regression analysis indicated that factors independently associated (p≤0.05) with a higher risk of catheter-acquired bacteriuria were as follows: hospitalization in orthopedics or urology, ethnic origin (Arabs > Jews), insertion of a catheter after the sixth day of hospitalization, catheterization outside the operating theaters, lack of administration of systemic antibiotics, unsatisfactory catheter care, and prolonged duration (≥7 days) of catheterization before infection occurred. The risk associated with catheterization outside the operating theater could be explained by its correlate, that is, catheterization for incontinence/obstruction as opposed to output measurement. Life-table analyses demonstrated that the daily risk for acquiring bacteriuria during the first six days of catheterization was higher among patients ultimately catheterized for ≥7 days than among those ultimately catheterized for < 7 days (P<0.05).
