French health insurance data indicate that approximately 15% of ambulatory antibiotic consumption is generated by hospital prescriptions. This extra-hospital consumption represents a greater volume than intra-hospital consumption. To date, hospital indicators of good antibiotic use do not include this outpatient dimension. This study will provide a snapshot of the proportion of ambulatory antibiotics generated by emergencies and analyze compliance with management recommendations.This study will serve as a basis for developing indicators of outpatient antibiotic consumption generated by hospital activity and for identifying specific intervention targets aimed at the misuse situations that have been highlighted.

This study will be carried out in the form of a repeated survey on a given day (4 days, one across each season), carried out by the local mobile antibiotic therapy team, using a standardized grid. The survey will concern all the medical records of the patients visiting any emergency department on the days of the survey.

The evaluation of antibiotic therapies prescribed in discharge orders will be carried out in accordance with local management recommendations by the site investigator (infectious disease and/or emergency medicine specialist), who will assess whether the prescription is in accordance with the recommendations or not.

• Visit on emergency department on one of the survey days
• Age ≥18

Exclusion Criteria:

• Patient opposed to the collection of his/her data
• Patient under guardianship or curatorship
