Kim: Multidrug-resistant Organisms and Healthcare-associated Infections

Abstract

Multidrug-resistant organisms (MDROs), including methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistnat Staphlyococcus aureus (VRSA), vancomycin-resistant enterococci (VRE), multidrug-resistant Acinetobacter baumannii, and multidrug resistant Pseudomonas aeruginosa have been a big challenge in control of healthcare-associated infection for a few decades in Korea. Carbapenem-resistant Enterobacteriaceae was most recently added to the utmost threatening MDROs. Because of the high and ever increasing level of MDROs and their healthcare-associated infections, prevention and control of MDROs has become a national priority. The above six MDROs have been designated as legislative healthcare-associated infections, which has to be reported to the Korean Center for Disease Control since January 2011 in Korea. This paper is provided to give current perspectives of MDROs and their healthcare-associated infections in Korea.
