Rapid control of an outbreak of vancomycin-resistant enterococci in a French university hospital
Summary
Vancomycin-resistant enterococci (VRE) are emerging in French hospitals. A VRE outbreak occurred in our hospital, prompting efforts to eradicate the organism. The following interventions were implemented simultaneously to control the outbreak: (1) creation of a VRE control committee; (2) cohorting of VRE carriers in a dedicated ward; (3) extensive screening of contact patients; (4) use of a sensitive technique for detecting VRE in rectal samples; (5) intervention of a dedicated team to reduce consumption of selected antibiotics; (6) information for, and education of, all hospital staff; and (7) electronic tracking of in-hospital transfer and readmission of VRE carriers and contact patients. Over a four-week period following admission of the index case, 37 carriers of a single strain of vanA vancomycin-resistant Enterococcus faecium were identified across seven units. A single additional readmitted contact patient was identified later. Of the 39 VRE-positive patients, two had urinary tract infections and 37 were colonised. Of the 32 patients with known VRE stool concentrations, 23 had low and nine high concentrations. One low-concentration patient precipitated transmission in another unit. This aggressive, co-ordinated, multifaceted strategy was successful in halting a widespread VRE outbreak in our hospital.
