range of re-useable microfibre cloths. Her investigations showed that the performance of the disposable microfibre cloth was notably worse.11
Debra feels that a lot of education is still required to make stakeholders aware that correct product selection can have an immediate positive impact within hospitals: “Cleaning is an essential pre-requisite to disinfection – the more effective the cleaning step is, the more effective the subsequent disinfection step is. Switching from disposable cloths and mops, which often have to be treated as clinical waste, to re-useable cleaning textiles is not only more effective regarding cleaning, but should also reduce the use of detergents, increase the efficacy of disinfectants and contribute towards the NHS Net Zero goal,” she comments. The moving of minor procedures to localised settings, as mentioned earlier, is an area where microfibre technology can assist. Improved efficacy, less of a reliance on harmful chemical agents and a reduced carbon footprint reinforces the need for this strategy. Taking into account the financial benefits of reduced chemical consumption and clinical waste adds further to what is already a compelling argument.
HPV and/or UVC?
There is no doubt the implementation of microfibre can have a significant positive
impact on everyday cleaning in healthcare, especially if this is supported by a robust disinfection process. However, manual disinfection alone is not the answer for all the reasons previously stated. Best practice is to supplement this with enhanced disinfection such as Hydrogen Peroxide Vapour (HPV) or Ultraviolet C Radiation (UVC), but which technology should you choose? HPV is very much seen as the ‘gold standard’ of disinfection, offering a log 6 reduction against a broad spectrum of pathogens including Clostridium difficile, yet
being 99.9% biodegradable with no rinsing obligation. The most advanced automated machines take liquid hydrogen peroxide and deliver it into a sealed room in a gaseous form, with a particle size no greater than 5µ. The gas is able to envelop all surfaces, even reaching inside cupboards and drawers and permeating the complex circuitry within medical devices to neutralise the most stubborn of microorganisms. The disinfectant has complete material compatibility, making it safe to use around the most sensitive electronic equipment, much of which may have touch screen interfaces or has been in direct physical contact with patients. Indeed, an ever-growing number of hospitals use HPV on a daily basis as part of their decontamination process for everything from diagnostic monitors to wheelchairs – even their cleaning trolleys and laundry cages. The COVID pandemic has seen numerous community and mental health Trusts adopt HPV technology, moving it beyond the established acute hospital customer base. We see this continuing further, as more and more localised treatment premises are being utilised for minor procedures. Demand has particularly increased for our remote-operated Oxy’Pharm Nocospray 2 machines as users seek a highly portable device with a capacity to decontaminate large areas: 1000mᶟ from a machine weighing just 6kgs.
