VIM-Positive Pseudomonas aeruginosa Sink Colonization Dynamics in Patient Rooms of a Dutch Tertiary-Care Hospital

Background: In hospitals, Verona integron-encoded metallo-β-lactamase (VIM)–positive Pseudomonas aeruginosa (VPPA) frequently colonize sink drains. Sink use has been shown to disperse VPPA to other surfaces surrounding sinks, creating a potential transmission source. Objective: Because VPPA have been isolated from sinks and patients within our hospital, we analyzed colonization dynamics in 2 sinks identified as VPPA hot spots between 2012 and 2018. Methods: One sink was in an intensive care unit (ICU) patient room and the other was in a gastrointestinal surgery (GIS) patient room. ICU patients... Mehr ...
