Is Ultraviolet disinfection the new technology for reducing the risk of hospital-acquired infections?

According to a study published in the American Journal of Infection Control, the use of ultraviolet (UV) disinfection technology in an operating room eliminated up to 97.7% of pathogens (infectious agent), which otherwise could have caused hospital-acquired infections. The UV light technology that was used is by PurpleSun, a New York based company. PurpleSun’s UV technology can reach and clean multiple surfaces in several seconds, compared to traditional disinfecting methods which use chemicals and does not eliminate bacteria as well. Traditional methods also take longer, since it is normally humans cleaning with a disinfectant.

What is ultraviolet disinfection?

Ultraviolet disinfection is the use of UV light to disinfect. UV light is absorbed by the DNA and RNA of microorganisms, which in turn causes changes in the structure of the DNA and RNA. This makes the microorganisms incapable of replicating. According to Bolton (2008), “because they cannot multiply, they cannot cause disease, even though technically they are still metabolically alive.” Ultraviolet disinfection is more commonly used for the disinfection of water, however, it may soon become an effective method to eliminate bacteria causing hospital-acquired infections.

PurpleSun: pioneer in ultraviolet disinfection technologies?

PurpleSun is a New York based company, and is set to be the first company to launch ultraviolet-based technology as a disinfectant. Their mission, as stated on their website, is to reduce hospital-acquired infections, in order to save lives, reduce costs, and enhance safety in healthcare facilities.

On their website, they have identified 3 limitations with hospitals’ current disinfection process:
1) Everything is done by hand
2) There are thousands of surfaces, and not enough time to clean them all
3) There is no room for human error

PurpleSun’s light disinfectant will allow rooms to be cleaned within seconds, disinfect all the surfaces in the room and has been proven to be very effective in eliminating harmful pathogens.

Is ultraviolet technology the next step that healthcare facilities must take to reduce the risk of HAIs?

Light technology as a disinfectant is still in the process of experimentation in healthcare facilities. That being said, the study conducted produced highly favorable results. PurpleSun as a company has also been doing extremely well on a global scale, being named one of the 50 most promising companies in the world. Furthermore, many firms and organizations have been investing in and partnering with the company, demonstrating that the company has a lot of potential. The effectiveness of ultraviolet light as a disinfectant is undeniable, but for now, we will just have to wait and see what the future holds for it in healthcare facilities.

One-wipe cleaning system in hospitals proven to be effective

According to Infection Control Today (2018), a recent study carried out in a hospital in the UK has determined that a “one wipe” cleaning system was proven to be more effective than the traditional “two wipes” system in reducing the risk of MRSA in hospitals. Between 2013-2016, the hospital had been using a “two wipe” system, which consisted of first using a detergent wipe and then using an alcohol wipe as a disinfectant. In May 2016, a universal cleaning and disinfection wipe was introduced to the healthcare facility, and it made a significant difference.

According to Infection Control Today (2018),

“Using a Poisson model the researchers demonstrated that the average hospital acquisition rate of MRSA/100,000 patient bed days reduced by 6.3 percent per month after the introduction of the new universal wipe.”

These results were significant, and led to a big change in how this UK healthcare facility cleans its equipment. Not only did the universal disinfectant wipes lead to higher efficacy, but they also led to higher efficiency, since healthcare workers now only have to go over the equipment once and are assured that it will be clean.

Keeping this in mind, there are many different types of disinfectant wipes to choose from.
