Effects of obtaining a blood culture on subsequent management of young febrile children without an evident focus of infection.

To assess the effects of obtaining a blood culture on the subsequent diagnostic and therapeutic management of young febrile children without an evident focus of bacterial infection, we carried out a randomized controlled clinical trial of this procedure in 146 children 3 to 24 months of age who presented to our emergency department with an unexplained temperature of 39.0 degrees C or higher. Random assignment to either have (67 children) or not have (79) a blood sample taken for culture resulted in groups equivalent in age, sex, weight, socioeconomic status, temperature at enrolment and laboratory test results. No differences were detected in the rates of subsequent hospital admission, outpatient visits, determination of complete blood count or other blood tests, urinalysis or urine culture, chest or other roentgenography, or administration of antibiotics or other medications. Knowledge of the absence of such differences should be helpful in evaluating the relative benefits and costs of blood culture for young febrile children.
