RESUMEN
In Southern France, approximately 4% of E. coli isolates from community-acquired urinary tract infections are extended spectrum beta-lactamase producers, while carriage rates for enterobacteriaceae (ESBL-E) range from 3 to 6%. General practitioners (GP) are unfamiliar with the management of patients harboring ESBL-E. Providing them with a specific tool kit should assist in their therapeutic approach and optimize antimicrobial prescription an ESBL-E tool kit was developed by a multidisciplinary team: infectious diseases (ID) specialists, microbiologists, pharmacologists, and nursing home staff. This tool kit includes treatment protocols, GP and patient information leaflets, a list of infection control measures, and contact details of ID physicians for specialized advice. A community-based (including nursing homes) prospective study was conducted in 2012 in Southeastern France to test the tool kit in the context of ESBL-E-related urinary tract infections (UTI). ESBL-E-related UTI were identified in 88 patients, 66 GPs were contacted by the microbiology laboratory, 56 stated they were offered the tool kit, 48 said they had received it, and 41 stated they had read its contents. Use of the tool kit was significantly correlated with appropriate antibiotic prescription, which concerned 36/39 tool kit users versus 13/20 non-users (p = 0.0125) and 40 GPs expressed an average satisfaction rate of 4.2 on a scale of 0 to 5. Availability of a specific tool for managing patients harboring ESBL-E, now completed with a website, can assist community-based GPs and improve antimicrobial prescription.
