BackgroundUrinary tract infection (UTI) is frequently encountered in the emergency department (ED). We assessed an antibiotic stewardship intervention tailored for the ED. The primary objective was improving overall adherence to agent choice and treatment duration. The secondary objective was a decrease in fluoroquinolone prescription.MethodsThis pre-post study included patients discharged from the ED with a UTI diagnosis. The intensive intervention period lasted three months and involved dissemination of guidelines, short lectures, incorporation of order sets into electronic ED charts and weekly personal audit and feedback. The following 11-month phase was a booster period consisting of monthly text messages of the treatment protocol. Assessment of adherence to the protocol was compared between the three-month pre-intervention period and the last two months of the intensive intervention period, as well as with the last two months of the booster period.ResultsA total of 177 patients were included in the pre-intervention period, 156 in the intervention period, and 94 in the late follow-up assessing the booster period. Median age was 49 (18-94) years, 78.2% were female, 84.8% had cystitis. During the intervention period, protocol adherence with antibiotic selection and duration increased from 41% to 84% (p < 0.001). Adherence remained high in the late follow-up period (73.4% vs. 41%, p < 0.001). Fluoroquinolone use decreased from 19.1% pre-intervention, to 5% in the intervention and 7.4% in the late follow-up periods (p < 0.001).ConclusionsAn antibiotic stewardship intervention in a busy ED resulted in adherence to treatment protocols, including a decrease in fluoroquinolone use. A monthly reminder preserved most of the effect for a year.Copyright © 2021 Elsevier Inc. All rights reserved.
