Multiresistant Microorganisms and Infection Control
Multiresistant organisms are usually bacteria that are not susceptible to multiple classes of antimicrobial agents. MROs result in increased morbidity and mortality and prolonged hospital stays, and many are readily transmitted in the healthcare environment. The most epidemiologically important multiresistant pathogens are methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant enterococci (VRE) and the multidrug-resistant Gram-negative bacteria. The strategies for the prevention and control of multiresistant organisms in the hospital settings include hand hygiene, standard and transmission-based precautions, isolation of the patients, use of personal protective equipment, environmental cleaning and management of care equipment. An organism-specific approach is necessary to reduce the risk of transmission and outbreaks.
