- The study investigates the risk of developing infections from multidrug-resistant organisms (MDROs) like carbapenem-resistant Enterobacteriaceae (CRE), methicillin-resistant Staphylococcus aureus (MRSA), and vancomycin-resistant enterococci (VRE) in patients who are colonized versus those who are not.
- Conducted as a retrospective cohort study at a tertiary care facility, the research analyzed data from 19,134 active surveillance tests in 2021 and found that colonized patients had significantly higher risks of infection (risk ratios of 4.6 for CRE, 8.2 for MRSA, and 22 for VRE).
