Risk factors for vancomycin-resistant enterococci infection and mortality in colonized patients on intensive care unit admission.

This study examined the incidence of and risk factors for development of vancomycin-resistant enterococci (VRE) infection and death in VRE-colonized patients in a medical intensive care unit. VRE colonization was identified in 184 patients (17.6%) in whom VRE perianal swab cultures were obtained. Of these, 28 (11.9%) developed VRE infection. Control of infectious sources is crucial to decrease development of VRE infections and optimize the survival of VRE-colonized patients.
