Overview

The control of antibiotic resistance requires a reduction in inappropriate prescriptions of broad-spectrum antibiotics (amoxillin-clavulanate (AMC), fluoroquinolones (FQ), third-generation cephalosporins (C3G)), particularly for urinary tract infections treated in primary care. Several studies have reported the positive impact of antibiotic susceptibility testing performed on urine cultures on the appropriate use of antibiotics.

The "selective reporting for antibiotic susceptibility testing ", defined as the restriction of the list of antibiotics mentioned in the report according to the antibiotic resistance profile, would allow, according to observational studies, a reduction of 25 to 70% of the initial prescriptions of broad-spectrum antibiotics and a 20% rate of antibiotic de-escalation (=reduction of the antibacterial spectrum of an antibiotic treatment after re-evaluation).

The objective is to assess the impact of disseminating a selective reporting for antibiotic susceptibility testing on the dispensing of broad-spectrum antibiotics prescribed by general practitioners (GPs) for E. coli positive urine cultures in adult women, compared to the dissemination of a standard antibiotic susceptibility testing.

Eligibility

Inclusion Criteria:

Patients :

  • women ≥18 years of age,
  • affiliated with the CPAM of Loire Atlantique (44) or Maine et Loire (49),
  • with a urine culture: i) analyzed by LabOuest, ii) positive for E. coli, and iii) associated with a prescription for antibiotics by a general practitioner in the period 7 days before and 14 days after the antibiotic susceptibility testing.

General practitioners :

  • practicing in primary care Loire Atlantique (44) and/or Maine et Loire (49),
  • having been consulted by at least 100 different patients in the 12 months prior to baseline,
  • having received at least one urine culture result for a woman ≥18 years of age analyzed by LabOuest over the 12 months prior to baseline.

Exclusion Criteria:

Patients :

  • hospitalized in the period 7 days before and 14 days after antibiotic susceptibility testing (data on antibiotics dispensed in healthcare institutions are not accessible via DCIR data),
  • with reimbursements for antibiotics prescribed by physicians in different practices over the period 7 days before and 14 days after antibiotic susceptibility testing.

General practitioners :

  • with a special practice (acupuncture, allergology, angiology).
  • not receiving any urine culture results analyzed by a laboratory of the LabOuest network in the year following the intervention

FAQs

Learn more about clinical trials

What is a clinical trial?

A clinical trial is a study designed to test specific interventions or treatments' effectiveness and safety, paving the way for new, innovative healthcare solutions.

Why should I take part in a clinical trial?

Participating in a clinical trial provides early access to potentially effective treatments and directly contributes to the healthcare advancements that benefit us all.

How long does a clinical trial take place?

The duration of clinical trials varies. Some trials last weeks, some years, depending on the phase and intention of the trial.

Do I get compensated for taking part in clinical trials?

Compensation varies per trial. Some offer payment or reimbursement for time and travel, while others may not.

How safe are clinical trials?

Clinical trials follow strict ethical guidelines and protocols to safeguard participants' health. They are closely monitored and safety reviewed regularly.
