Diagnostic Stewardship Opportunities for Emergency Department Evaluation of Children with Suspected Urinary Tract Infection
Abstract
Background: Among children who start antibiotics for suspected urinary tract infection (UTI) in emergency departments (EDs), 40-60% have negative urine cultures or other results inconsistent with UTI. Practices contributing to excess antibiotic exposure are not well understood. The goal of this study was to understand diagnostic and post-encounter follow-up processes in children who received antibiotics, in order to define targets for intervention. Methods: We identified encounters by children evaluated in two pediatric EDs, over 2 months in the first ED and 9 months in the second ED, to balance different visit volumes. Children 2 months-17 years old were included if they had a urinalysis (UA) and/or urine culture performed, were assigned a primary or secondary diagnosis code for UTI, and initiated antibiotics. Patients were excluded if they received antibiotics prior to the encounter, had prior urologic surgery or device placement, or were immunocompromised or pregnant. Data abstracted by chart review included demographics, documented symptoms, test results, and documented urine culture review and management. Possible UTI symptoms per pediatric criteria included fever, dysuria, urinary frequency, urgency, or hesitancy, suprapubic, abdominal or flank pain, foul smelling urine, or new urinary incontinence. In both EDs, nurses review urine cultures and document changes to treatment plans. Final urine culture results were considered inconsistent with UTI if there was 1) no…
