Patient and laboratory data were abstracted from the hospital\u2019s medical informatics database. We identified catheter-associated urinary tract infections (CAUTIs) in the ICUs by routine infection prevention surveillance. Cultures without urinalysis or urine microscopy were defined as \u201cisolated.\u201d The primary outcome was the proportion of isolated urine cultures obtained. We used multivariable logistic regression to assess predictors of isolated cultures.<\/jats:p><\/jats:sec><jats:sec id=\"S0899823X16003111_abs6\" sec-type=\"results\"><jats:title>RESULTS<\/jats:title><jats:p>During the study period, 14,743 urine cultures were obtained (63.5 cultures per 1,000 patient days) during 11,820 patient admissions. Of these, 2,973 cultures (20.2%) were isolated cultures. Of the 61 CAUTIs identified, 31 (50.8%) were identified by an isolated culture. Predictors for having an isolated culture included male gender (adjusted odds ratio [aOR], 1.22; 95%; confidence interval [CI], 1.11\u20131.35], urinary catheterization (aOR, 2.15; 95% CI, 1.89\u20132.46), ICU admission (medical ICU aOR, 1.72; 95% CI, 1.47\u20132.00; surgical ICU aOR, 1.82; 95% CI, 1.51\u20132.19), and obtaining the urine culture \u22651 calendar day after admission (1\u20137 days aOR, 1.91; 95% CI. 1.71\u20132.12; &gt;7 days after admission aOR, 2.81; 95% CI, 2.37\u20133.34).<\/jats:p><\/jats:sec><jats:sec id=\"S0899823X16003111_abs7\" sec-type=\"conclusions\"><jats:title>CONCLUSIONS<\/jats:title><jats:p>Isolated urine cultures are common in hospitalized patients, particularly in patients with urinary catheters and those in ICUs.
