Use of antimicrobial coatings in healthcare

The dissemination of infectious diseases within the healthcare environment is an issue both persistent and increasing, globally.¹ Statistics from nearly a decade ago indicate there is approximately 4 million healthcare-associated infections (HCAIs) annually in Europe, and around 1.7 million in the US.2 The issue is further exacerbated by the development of antimicrobial resistance (AMR) and disinfectant resistance. Common fomites that microbes are able to adhere to within the healthcare environment include: solid-gas interfaces such as door handles, switches, buttons, clothes, curtains, keyboards (etc), and solid-liquid (water) interfaces such as taps, drains and shower.¹

Technology frequently presents innovative products or ideas that, over time, can cause a revolutionary effect within Infection Prevention and Control (IPC). Infectious diseases and resulting HCAIs present a considerable challenge to human health across healthcare environments globally.³ A relatively novel concept that has been gaining traction within the healthcare industry is the use of antimicrobial coatings (AMCs). While the knowledge of AMCs is not necessarily new, its widespread application within healthcare is yet to be seen.

Antimicrobial coatings have the potential to provide an innovative addition to existing infection prevention and control programmes. It is well documented within scientific literature that surfaces can pose a significant source of microbiological contamination within both healthcare and the wider environment.⁴ It is also evident that traditional disinfectant products, while effective when wet at the point of application, do not provide any long-lasting protection.
