  • Coverage by the French health insurance system (Social Security)
  • Written informed consent obtained from the patient, or, if the patient is not able to give written consent, from his or her legally designated representative (trusted person designated by the patient, or failing that a family member) and, failing that due to the urgency of the situation, inclusion will be performed by the investigator within the therapeutic window

  • Moribund patient
  • End-of-life decision
  • Previous inclusion in the present study
  • On-going VAP (currently being treated)
  • VAT due to pathogens with intrinsic naturally amikacin resistance
  • On-going therapy with amikacin IV
  • AKI stage 2 or 3 of the KDIGO classification and/or advanced chronic kidney failure (glomerular filtration rate <30 mL/min), except in patients under renal replacement therapy (RRT)
