Objectives The aims of the study were to investigate whether the prevalence of urinary tract infections (UTIs) in febrile infants aged 2 to 12 months with bronchiolitis is higher than the presumed prevalence of asymptomatic bacteriuria (1%) in similarly aged patients and thus to determine whether UTI testing is necessary for these patients. Methods This was a prospective cohort study in which we enrolled a convenience sample of febrile infants aged 2 to 12 months with a clinical diagnosis of bronchiolitis. All patients were seen in the emergency department at a large children's hospital between November 1, 2011 and April 15, 2012, had reported or documented fever higher than 38°C, and had urine collected for determination of the presence of UTI. After the conclusion of enrollment, a chart review was conducted to assess missed cases. Results Positive urine cultures were found in 6/90 (6.7%) patients (confidence interval, 2.5%-13.9%). The positive urine cultures and urinalysis results were found in 4/90 (4.5%) patients (confidence interval, 1.2%-11%). Conclusions In our patient population, a significant proportion of infants aged 2 to 12 months who present with bronchiolitis and fever have a concurrent UTI. Obtaining a urine specimen for UTI testing should be considered in infants aged 2 to 12 months with bronchiolitis and fever. A larger multicenter study is needed to further assess the risk factors for UTIs in this patient population.
