ObjectivesUrinary tract infections (UTIs) are a common diagnosis within the pediatric emergency department (ED). Because of the necessary delay in obtaining urine culture results, clinicians must decide whether to prescribe antibiotics for a suspected UTI before urine culture results. The primary objective of this study was to identify the proportion of children given empiric antibiotics who subsequently did not meet consensus definition of an UTI. The secondary objective was to identify factors associated with return visits to the ED after an index visit for UTI. We also attempted to identify predictors of prescription of empiric antibiotics for children who did not have a UTI.MethodsThis was a retrospective chart review of all patients between the ages of 2 months and 18 years diagnosed with a UTI between July 2016 and June 2017 in the ED of a single urban quaternary care center. Patients were excluded for the following reasons: use of bag for urine collection, subsequent admission to the hospital, receipt of antibiotics within the previous 3 days, use of antibiotics for an indication other than a UTI, and urine culture obtained at an outside facility.ResultsOf 404 included patients, 389 (96.2%) were discharged on antibiotics and 243 (62.4%) did not have a UTI. On the multivariate analysis, age ≧ 36 months was associated with increased odds of receiving antibiotics and not having a UTI while both ≥1+ leukocyte esterase and ≥1+ nitrites on urinalysis were associated with decreased odds of receiving antibiotics and not meeting UTI criteria. Sixty-two patients revisited the ED within 30 days of the initial visit, 24 (38.7%) of which met criteria for UTI during the index visit. Prescription of antibiotics at the time of the index visit was associated with decreased odds of reutilization, whereas an extended-spectrum β-lactamase producing organism cultured from urine at the index visit was associated with increased odds of reutilization.ConclusionsA high number of patients discharged on empiric antibiotics did not meet criteria for a UTI. We did not identify clinically useful factors that predicted prescription of empiric antibiotics for children who do not have a UTI. We believe that unnecessary antibiotic prescriptions could be substantially decreased by decreasing empiric use of antibiotics coupled with reliable follow-up for positive urine cultures.Copyright © 2021 Wolters Kluwer Health, Inc.
