According to the guidelines, patients with MSSA bacteremia will be treated with intravenous antimicrobial therapy for 2 weeks. The total treatment duration will be left to the choice of the clinician in charge of the patient but will be not below 14 days. Nevertheless, after 7 days, the nature of the antimicrobial treatment will be let to the choice of the clinician in charge of the patient. Treatment duration according to the final diagnosis will be defined by consensual guidelines. These guidelines are being developed using a methodology inspired by the Delphi method as part of the Tep-Star clinical trial. The coordinating investigator of the Tep-Star trial is Vincent Le Moing and its scientific director is Xavier Duval. Both are members of the scientific committee of this trial. Antimicrobials for switch of the first treatment line will be let to the choice of the investigator in charge of the patient.
