Daily urine cultures were obtained from each newly catheterized patient, but the results of these cultures were not revealed to his or her physician. During the study, one of the investigators (DGM) reviewed each patient's record and made a judgment as to which of the diagnostic tests and treatments ordered and what incremental length of stay could reasonably be ascribed to his or her CAUTI. The total hospital costs for each patient were also obtained.<\/jats:p><\/jats:sec><jats:sec id=\"S0195941700072374_abs5\"><jats:title>Results:<\/jats:title><jats:p>Overall, 235 patients acquired CAUTIs during the study; most of the CAUTIs were completely asymptomatic, and only 52% were diagnosed by the patients' physicians using the hospital laboratory. Only 1 patient with a CAUTI had a secondary bloodstream infection. Thirty-three (13%) of the CAUTIs were caused by <jats:italic>Escherichia coli<\/jats:italic>; 63 (25%) by <jats:italic>Klebsiella, Enterobacter, Citrobacter, Pseudomonas aeruginosa<\/jats:italic>, or other antibiotic-resistant, gram-negative bacilli; 87 (35%) by enterococci or staphylococci; and 67 (27%) by <jats:italic>Candida<\/jats:italic> species. The 123 CAUTIs diagnosed by the hospital laboratory were judged to have been responsible for an additional $20,662 in extra costs of diagnostic tests and $35,872 in extra medication costs, a mean of $589 (median, $356) per CAUTI. CAUTIs caused by <jats:italic>E. coli<\/jats:italic> cost considerably less than infections caused by other gram-negative bacilli ($363.3 \u00b1 $228.2 vs $690.4 \u00b1 $783.7; <jats:italic>P<\/jats:italic> = .02) or yeasts ($821.2 \u00b1 $2,169.9).
