“…A potentially innovative approach to limiting environmental contamination is the use of spontaneously antimicrobial surfaces. Of these, copper-based microfibre cleaning systems [15] or copper furnishings look particularly promising, although the latter are expensive and still in need of regular cleaning [16].…”

ObjectiveTo determine whether microbial contamination of door handles in two busy intensive care units and one high dependency unit was related to their design, location, and usage.DesignObservational study of the number of viable bacteria on existing door handles of different design at defined entry/exit points with simultaneous data collection of who used these doors and how often.SettingTwo busy specialised intensive care units and one high dependency unit in a tertiary referral NHS neurological hospital.Main outcome measuresSurface bacterial density on door handles with reference to design, location, and intensity of use.ResultsWe found a significant correlation between the frequency of movements through a door and the degree to which it was contaminated (p = <0.01). We further found that the door's location, design and mode of use all influenced contamination. When compared to push plate designs, pull handles revealed on average a five fold higher level of contamination; lever handles, however, displayed the highest levels of bacterial contamination when adjusted for frequency of use. We also observed differences in contamination levels at doors between clinical areas, particularly between the operating theatres and one of the ICUs.ConclusionsDoor handles in busy, “real life” high acuity clinical environments were variably contaminated with bacteria, and the number of bacteria found related to design, location, mode and frequency of operation. Largely ignored issues of handle and environmental design can support or undermine strategies designed to limit avoidable pathogen transmission, especially in locations designed to define “thresholds” and impose physical barriers to pathogen transmission between clinical areas. Developing a multidisciplinary approach beyond traditional boundaries for purposes of infection control may release hitherto unappreciated options and beneficial outcomes for the control of at least some hospital acquired infections.

“…These surfaces may provide a less toxic approach than the use of chemical disinfectants and are broadly microbicidal. [42][43][44] However, a constant source of photoactivation is required, and it is unclear whether these surfaces are sporicidal. Studies are still required on long-term disinfecting properties of these surfaces in the real-world hospital environment.…”

This chapter provides the most up-to-date advice on infection prevention and control (IPC) of the four most common healthcare-associated infections (HAIs). These are: surgical site infections; infection associated with peripheral IV line/cannula and central line-associated bloodstream infections (CLABSIs); catheter-associated urinary tract infections (CAUTI); and hospital-acquired and ventilator-acquired pneumonias (VAP). The chapter examines and summarizes various key elements and discusses implementation of HAI care bundles and high impact interventions which are necessary to reduce these infections.

“…hand-rails, soap dispensers, bedding, curtains) are much lower than other sites (e.g. floor) (Hamilton et al, 2010), and porous surfaces are more difficult to clean (Oie et al, 2005). To explicitly model these environmental sites it is necessary to choose the appropriate site, sample for organisms at appropriate intervals, and follow up patients for contact rates with the site as well as their carriage status.…”
