Background: Vancomycin-resistant Enterococci (VRE) can cause outbreaks through contact transmission. In this study, we experienced a VRE outbreak in a cancer center in Japan. Herein we report for the first time the VRE transmission pathway and risk factors for VRE acquisition in a cancer center.
Methods: After identifying the first case of VRE, stool screening for VRE and multifaceted infection-control were implemented in the entire ward. To determine risk factors for VRE acquisition, we conducted a case-control study comparing VRE-positive and -negative patients.
Results: Of the 177 patients who underwent screening tests, 13 were positive for VRE, of whom 9 (69.2%) were male and 4 (30.7%) were female. The age range was 52-83 years (median, 67.0), and all patients had solid tumors. Only one patient was treated for VRE infection, and no deaths due to VRE infection were reported.
Conclusion: In our study, "diaper use" was a risk factor for VRE acquisition. It is important to thoroughly implement infection control measures, primarily hand hygiene and use of personal protective equipment, as well as environmental cleaning to terminate an outbreak.
