About

Urinary tract infections (UTIs) are one of the most common bacterial infections managed in general practice: they are the 2nd site of community-acquired bacterial infection after respiratory infections (4-6 million consultations per year in France).

UTIs represent 15% of total antibiotic prescriptions in France. Antibiotics recommended for UTIs, except for cystitis, are considered as "critical" (highly generating bacterial resistances). UTIs are a potential source of antibiotic resistance: often inappropriate antibiotic prescriptions, evolution of the resistance profiles of the bacteria involved, emergence of multi-resistant strains.

The first hypothesis is that there are other profiles of clinical UTI situations in general practice than typical cystitis or pyelonephritis, including intermediate forms.

The second hypothesis is that these intermediate forms of UTI are subject to longer durations of antibiotherapy, and that probable explanatory factors need to be identified.

Full description

Urinary tract infections (UTIs) are one of the most common bacterial infections managed in general practice: they are the 2nd site of community-acquired bacterial infection after respiratory infections (4-6 million consultations per year in France).

UTIs represent 15% of total antibiotic prescriptions in France. Antibiotics recommended for UTIs, except for cystitis, are considered as "critical" (highly generating bacterial resistances). UTIs are a potential source of antibiotic resistance: often inappropriate antibiotic prescriptions, evolution of the resistance profiles of the bacteria involved, emergence of multi-resistant strains.

Current guidelines classify UTIs as "uncomplicated UTI" (cystitis and pyelonephritis) and "UTI at risk of complication" (cystitis, pyelonephritis and male UTI) [1-2]. However, in primary care, pathologies are diagnosed at an early stage: the clinical signs usually described by scientific societies are not always all found, and the descriptions are not always adapted to the realities encountered in general practice [3-6]. Some clinical situations do not fit into the systematic categories of the guidelines, with "intermediate" forms (such as pain in the lumbar fossae without fever "cysphritis" or other atypical presentations) [3]. The current literature in general practice highlights these issues: the need for prospective cohorts in real-life practice to identify these profiles and develop more appropriate guidelines [3-6]. Treatment for these intermediate forms is not obvious and is often empirical: potentially longer antibiotherapies, with possible worsening of antibiotic resistance [7].

The first hypothesis is that there are other profiles of clinical UTI situations in general practice than typical cystitis or pyelonephritis, including intermediate forms.

The second hypothesis is that these intermediate forms of UTI are subject to longer durations of antibiotherapy, and that probable explanatory factors need to be identified.
