An outbreak of vanA vancomycin-resistant Enterococcus faecium in a hospital with endemic vanB VRE Angus Hughes, Susan Ballard, Sheena Sullivan, Caroline Marshall Infection, Disease & Health DOI: 10.1016/j.idh.2018.12.002 Copyright © 2018 Terms and Conditions

Figure 1 Timeline of the outbreak: Length of stay on CTS, ICU and other hospital wards for cases and implementation of key infection control measures. CTS-pos and ICU-pos = stay on ward with any positive vanA VREfm isolate; CTS-neg and ICU-neg = stay on ward when negative for vanA VREfm or status not yet known (assumed negative); other_ward = stay on any other ward in hospital excluding ICU and CTS and regardless of vanA VREfm status. Black dots represent vanA VREfm acquisitions detected on discharge screening to other_ward or from hospital. Note. CHG = Chlorhexidine gluconate; CTS = cardiothoracic surgery; ICU = intensive care unit; VRE = vancomycin-resistant enterococci; VREfm = vancomycin-resistant Enterococcus faecium.

Figure 2 Epidemiological curves of new vanA VREfm cases on ICU (a) and CTS ward (b) over the course of the outbreak. Timing of some key interventions applied specifically to each ward are indicated. Note. CHG = Chlorhexidine gluconate; CTS = cardiothoracic surgery; ICU = intensive care unit; VRE = vancomycin-resistant enterococci; VREfm = vancomycin-resistant Enterococcus faecium.
