Mastering hOSpital Antimicrobial Resistance

Better understand the dynamic of AMRB transmission• the real-time analysis of the relative contribution of exposure to

antibiotics;• the intrinsic characteristics of epidemic clones that contribute to

inter-individual transmission;• the identification of factors contributing to the transmission of strains

between individuals in the hospital population and community;

Document interactions between• medical and nursing staff• patients to patients• patient to medical staff

Document contact frequencies• monitor the dynamic (inter & intra contact)• characterize the interaction network
