Utility of Urine Cultures in Predicting Blood Culture Susceptibilities in Patients with Bacteremic Urinary Tract Infection.

In a review of 428 patients with bacteremic urinary tract infections, urine culture susceptibility results accurately predicted blood culture results when the same organism was isolated from both cultures. Early targeted therapy using urine culture results can potentially reduce broad-spectrum antibiotic exposure and its associated adverse effects and the length of hospitalization.
