The research time period has been separated into two intervals called while: Carbapenem non-restricted period of time (CNRP) along with carbapenem-restricted interval (CRP). Throughout CNRP, no limitations were made on the usage of carbapenems. During CRP, using carbapenems wasn't authorized when there was a substitute for carbapenems. Principal Endpoint: MDRAB disease right after ICU programs. #l
