Design outcomes

Primary

MeasureTime frame
Current primary outcome measure as of 09/05/2023: CRKP eradication: Eradication [clearance] rate of CS-CRKP assessed by culture positivity of rectal swabs for CRKP at day 14 [day 7 post Rx] _____ Previous primary outcome measures: 1. Eradication of CRKP assessed by culture positivity of rectal swabs for CRKP at day 28 post-intervention 2. CRKP bloodstream infection (bacteremia) assessed by blood culture for 28 days post-intervention 3. CRKP-related death will be captured by active follow-up of patients in both groups during hospitalization and for 28 days, whichever is longer

Secondary

MeasureTime frame
Current secondary outcome measure as of 09/05/2023: 1. Incidence of CS-CRKP bacteremia during the same hospitalization 2. In-hospital all-cause mortality during the same hospitalization 3. Incidence of colistin resistance in positive rectal swabs at day 14 [day 7 post Rx] _____ Previous secondary outcome measures: Development of resistance to colistin evaluated by performing susceptibility testing of colistin for all post-intervention CRKP isolates from any site for 28 days
