Participants from 127 institutions reviewed a total of 14,739 urine-culture specimens and submitted data related to microbiological results, patient gender, age, and site of specimen collection. If more than 2 isolates were found in quantities of >10,000 colony-forming units (CFU)/mL, the urine culture was classified as contaminated. The overall rate of urine-culture contamination and rates by gender, age, and collection site based on these criteria are listed below.The urine-culture contamination rate for patients less than two years old may not be comparable due to the low frequency of events. |
