Impact of Modifications to the Rendering of the Antibiogram on the Prescriptions of Meropenem in Pseudomonas Bacteremia
Modification of the rendering of the antibiogram at the Strasbourg University Hospital in November 2019 with the appearance of the concept of standard dose or high dose sensitivity. This modification seems to have favored an inappropriate overprescription of Meropenem (the only antibiotic made at standard dose) in Pseudomonas infections sensitive to other beta-lactams. In June 2021, it was therefore decided to mask sensitivity to carbapenems by default in the rendering of Pseudomonas antibiograms when the strain was sensitive to a narrower spectrum beta-lactam (restricted antibiogram). The aim of this study is to evaluate the impact of these changes in the antibiogram on antibiotic prescriptions.
