UK hospitals trial ‘better than bleach’ cleaning solution

A new cleaning solution can clean hospitals better than traditional products, UK researchers say.

The product – Pathisol – can disinfect surfaces in two minutes, five times faster than bleach. It also kills 99.99% of pathogens, including hospital superbug CClostridium difficile.

A team of researchers at Teesside University has been running independent trial New from North Tees and Hartlepool Foundation Trust in the North of England.

Developed by hospital subsidiary NTH Solutions, it contains a chemical called “hypochlorous acid” that is widely used in the United States.

Dan Sullivan, head of education and development at NTH Solutions, told Forbes: “We know about hypochlorous acid from studies conducted in the US, but there is no clear evidence that it works in acute clinical settings such as NHS hospitals. ”

“Our study aims to provide this evidence through robust, independent trials conducted in live clinical settings.”

Rebecca Denton Smith, head nurse at North Tees and Hartlepool, added: “Pathisol is a natural product. It’s called hypochlorous acid and it’s in our bodies.

“It’s our natural first line of defense against infection. It’s easy to manufacture, easy to apply, and most importantly, it kills a wide variety of pathogens.”

In addition to being safer, cheaper to manufacture and less harmful to the environment than bleach, Pathisol can be manufactured on-site in hospitals, which could reduce the need for plastic bottles, the company said.

The three-phase trial is still ongoing, with earlier research efforts delayed by the pandemic. But it has shown positive results.

In the first phase, researchers randomly selected locations across the hospital’s three wards, and then sent the samples to the hospital’s microbiology lab for testing.

There, they were left for 24 hours to observe colony growth. This gave the researchers a basic understanding of the pathogens that live in each ward during normal cleaning.

In the second stage, replace the normal cleaning solution with Pathisol.

Third, researchers are trying a new way to use hypochlorous acid: spray it on surfaces Handheld electrostatic device.

Swabs from each phase of the trial were compared to previous results to determine the effectiveness of the new solution.

So far, the results for Pathisol and the new application method have been positive.

Dan Sullivan said: “We are awaiting independent validation of the data, but early indications are that Pathisol has successfully reduced the microbial load in the test area and that the microbial load has been enhanced following the application of electrostatic technology.. ”

Teesside University plans to release the data in due course.

These promising results could translate into tangible benefits for hospitals, said Tony Sullivan, the company’s manager of environmental and decontamination services.

He said: “Pathisol takes up to two minutes to sanitize surfaces, while bleach can take 10 minutes. In NHS terms, this means we can use [the product] To disinfect, we can deep clean the ward without the need for a 24-hour evacuation. “
