Purpose: To assess the prevalence of multidrug-resistant organisms (MDROs) in inter-hospital transferred critically ill patients.
Methods: This is a retrospective study. The study population comprised patients who were transferred from other hospitals or health care units into the medical or surgical intensive care unit of Samsung Medical Center from January 2012 to December 2014. We evaluated the acquisition of clinically significant MDROs including methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant Enterococci (VRE), extended-spectrum beta-lactamase (ESBL)-producing Gram-negative bacteria, and carbapenem-resistant Gram-negative bacteria (CRGNB).
Results: Three hundred and twenty-one patients were included in this study. One hundred and fifty-one patients (47.0%) had at least one species of MDRO, 21.5% in MRSA, 27.1% in VRE, 15.6% in CRGNB, and 3.7% in ESBL. The prevalence of MDROs was significantly higher in male (52.7%), patients with diabetes (61.6%), patients with combined infectious diseases (51.6%), and medical patients (49.3%). Patients with MRSA had significantly longer length of stay than the patients without MRSA. The patients with CRGNB had higher mortality than the patients without CRGNB.
Conclusion: The prevalence of MDROs in inter-hospital transferred critically ill patients was very high. Patients with MDROs in this study had longer hospital stay and higher mortality. These patients require more attention for isolation and hygiene protocols, and antibiotic choices.
