Antibiotics associated with acquisition of carbapenem-resistant Pseudomonas aeruginosa in ICUs: a multicentre nested case-case-control study

摘要

Background: Carbapenem-resistant Pseudomonas aeruginosa (CRPA) strains are involved in severe infections, mostly in ICUs. Exposure to antibiotics other than carbapenems may be associated with isolation of CRPA; therefore, we aimed to identify those antibiotics using the case-case-control study design.
