Design outcomes

MeasureTime frameDescription
Number of Participants With Acquisition of Any New Antibiotic-resistant OrganismOutcome will be measured approximately every 3 days after enrollment throughout hospitalization, and at the time of discharge (the median duration of hospitalization was 13.5 days).Acquisition in the gastrointestinal tract of any new antibiotic resistant organism post-enrollment. Antibiotic resistant organisms include: C. difficile, vancomycin-resistant enterococci (VRE), multidrug-resistant Acinetobacter baumannii, multidrug-resistant Pseudomonas, ciprofloxacin-resistant Enterobacteriaceae, extended-spectrum betalactamase (ESBL) producing Enterobacteriaceae.
