Effect of MVX (Titanium Dioxide) on the Microbial Colonization of Surfaces in an Intensive Care Unit

The investigators have designed a prospective pre-post evaluation time-based pilot study addressing the microbial colonization of surfaces in four rooms of the ICU before and after coating with titanium dioxide (MVX). During a pre-intervention period cultures will be taken every 7 days from 10 prespecified and marked sites per room for a total duration of 4 weeks (sink, wall, floor, bed rail, door handle, ceiling, keyboard patient room, nurse call button, bedside table and monitor arm). After coating of the rooms with MVX another 4 weeks observation period will be used to gather samples in the post-intervention period.
