Overview
Prospective, multicenter, non-interventional study conducted over 6 months, including patients presenting to the emergency department with suspected urinary tract infection managed as outpatients and discharged with or without empiric antibiotic therapy.
Discharge antibiotic prescriptions are reviewed, with subsequent reassessment and optimization of treatment based on urine culture and susceptibility results
Description
Urinary tract infections are a frequent cause of emergency department visits, accounting for substantial antibiotic use. Data from the OSCOUR (Organisation de la Surveillance Coordonnée des Urgences) network estimate around 5,000 weekly visits. Resistance rates among Enterobacteriaceae in urine samples are particularly high, largely driven by the widespread use of broad-spectrum antibiotics, especially fluoroquinolones, which are commonly prescribed as empiric therapy. Given their potential for serious adverse effects and their strong selective pressure for resistance, stricter control of their use is warranted, yet remains insufficient.
In current emergency practice, conditions such as pyelonephritis or male urinary tract infections are often treated with broad-spectrum antibiotics that are continued even when pathogens are susceptible to narrower agents. De-escalation to narrower-spectrum therapies would help preserve the microbiota and limit resistance.
This study is a prospective, multicenter, non-interventional observational study conducted over 6 months. It includes patients presenting to the emergency department with suspected urinary tract infections managed on an outpatient basis and discharged with or without empiric antibiotic therapy. Antibiotic treatments are reassessed 48 - 72 hours after inclusion by a physician, allowing for patient follow-up and potential modification of the initial prescription based on urine culture and susceptibility results, in accordance with current guidelines.
The study aims to assess the value of this reassessment strategy in improving antimicrobial stewardship for urinary tract infections in emergency settings and to inform future optimization of clinical practices.
