In January, the first ever study into the effect of silver antimicrobial products on a healthcare environment was published in the Journal for Infection Prevention*.
The pilot trial was carried out by BioCote Ltd in partnership with the Heart of England NHS Foundation Trust in the UK.
The trial involved the Trust furnishing an outpatient unit (unit A) with BioCote® protected products including blinds, tiles, door handles, sack holders and light switches and also a number of untreated products. A similar unit (unit B) containing untreated items was used as a control. After both units had been in use for 12 months, swabs were collected from both the BioCote® treated and untreated products in both units and the levels of bacteria were compared.
Results showed an average reduction in bacteria of 95.8% on BioCote® treated products, compared to untreated items. This suggests that the high level of antimicrobial efficacy regularly demonstrated with laboratory product validation can be reproduced in a real-life environment.
Reductions were also seen on untreated products: bacterial counts were 43.5% lower on untreated products in unit A (the same environment as BioCote® treated products), compared with untreated products in unit B. This finding suggests that the lower numbers of bacteria on BioCote® treated surfaces results in lower numbers on untreated surfaces, because there are fewer bacteria being transferred from one to the other.
Using a number of BioCote® antimicrobial products may therefore help the decontamination of the wider environment.
The pilot study also shows how BioCote® protected products can be used alongside cleaning practices to help continually and in the wider healthcare environment.
