We evaluated 800 hospitalized patients with a complicated urinary tract infection in whom on the day of start of antibiotic treatment both a blood- and a urine culture were obtained.
In 70% of patients urine cultures were positive and blood cultures in 29%. In 7% of patients uropathogens caused bacteraemia with a pathogen that was not isolated from urine. Receiving antibiotic therapy at the moment of hospitalization was the only factor independently associated with discordant culture results (OR, 2.06; 95% CI, 1.18-3.61). For those receiving antibiotics at the moment of hospitalization blood cultures have additional diagnostic value over urine cultures.
