Vancomycin-resistant enterococci (VRE) (also referred to as glycopeptide-resistant enterococci) have emerged as significant nosocomial pathogens. Immunosuppression and indwelling devices are risk factors for invasive infections ( ). Transmission on hospital wards is the major source of spread of these antibiotic-resistant organisms. Infection rates can be reduced by screening high-risk groups ( ). Patients colonized with VRE are isolated to prevent transmission. The laboratory, in conjunction with the Infection Control Program, should decide which groups of patients to screen and the frequency of screening depending on the local epidemiology, unless regulations state otherwise ( ).
