Why optimizing antibiotics (Abx) ?
Major Clinical and Health Concerns
Negative impacts on patients’ health
Toxicity
Main risk factor of C. difficile
Increased length of stay
Inadequate spectrum coverage
Increased Abx resistance
Bacteria
Abx
Mutations
Resistant bacteria
It is costly
713-Bed Academic Hospital, 30 000 hospitalizations
10 000 hospitalisations
35 000 Abx prescriptions
210 000 doses
1,7 M$/ year
50% inappropriate
