Publications

Pub 202 - Practical Aspects of Reducing Bioburden with Copper: Clinical Case Study: Selly Oak Hospital, Birmingham open pdf
There is now substantial scientific evidence to support the replacement of frequently touched equipment and fittings in the clinical environment with those incorporating copper to reduce contamination and therefore reduce the risk of infection. The Copper Clinical Trial, conducted on a busy medical ward at Selly Oak Hospital, demonstrated a 90-100% reduction in contamination on coppercontaining vs standard surfaces. The experience of fitting out the test ward with a full range of copper-containing products has made a major contribution to the understanding of the practical application of the science. (Presented at IHEEM 2009 Conference, Harrogate.

Role of copper in reducing hospital environment contamination web link
A.L. Casey, D. Adams, T.J. Karpanen, P.A. Lambert, B.D. Cookson, P. Nightingale, L. Miruszenko, R. Shillam, P. Christian and T.S.J. Elliott, J Hosp Infect (2009), doi:10.1016/j.jhin.2009.08.018.
The environment may act as a reservoir for pathogens that cause healthcare-associated infections (HCAIs). Approaches to reducing environmental microbial contamination in addition to cleaning are thus worthy of consideration. Copper is well recognised as having antimicrobial activity but this property has until now not been applied to the clinical setting.
