Summary

As of 2019, the CA-SFM (Comité de l'Antibiogramme de la Société Française de Microbiologie) recommends that the letter "I" or the term "intermediate" on antibiotic antibiograms. Instead, it is recommended that the term "sensible à forte posologie" or "SFP". These recommendations have been in place since 21/01/2022 at Nancy University Hospital. Pseudomonas aeruginosa is the bacterium most affected by this change, as it has a high proportion of "high dosage" antibiotics. Staphylococcus aureus is the most widely isolated bacterium, and also impacted by the change in antibiotic susceptibility testing. The aim of this change in recommendations is to guarantee the efficacy of the proposed molecules. Main objective Evaluate the impact of the change in antibiogram recommendations in samples positive for Pseudomonas aeruginosa and Staphylococcus aureus on antibiotic therapy (prescribed dosage) Secondary objectives * Evaluate the impact of changing the way antibiograms in Pseudomonas aeruginosa and Staphylococcus aureus on antibiotic therapy (molecule prescribed). * Evaluate the impact of changing the way antibiograms on antibiotic therapy (molecule and dosage prescribed), depending on the strain identified (Pseudomonas aeruginosa or Staphylococcus aureus). * Describe the impact of changing antibiograms in Pseudomonas aeruginosa and Staphylococcus aureus on antibiotic therapy (molecule and dosage prescribed) by department.
