New disinfection technique could revolutionize hospital room cleaning

December 9, 2011, Queen's University

A Queen's University infectious disease expert has collaborated in the development of a disinfection system that may change the way hospital rooms all over the world are cleaned as well as stop bed bug outbreaks in hotels and apartments.

"This is the future, because many hospital deaths are preventable with better cleaning methods," says Dick Zoutman, who is also Quinte Health Care's new Chief of Staff. "It has been reported that more than 100,000 people in North America die every year due to at a cost of $30 billion. That's 100,000 people every year who are dying from largely preventable infections."

Dr. Zoutman has also used this disinfection technology to kill . A major U.S. hotel chain has already expressed interest in the technology because of its potential to save the company millions of dollars in lost revenue and infected furniture.

Dr. Zoutman worked in collaboration with Dr. Michael Shannon of Medizone International at laboratories located in Innovation Park, Queen's University. Medizone is commercializing the technology and the first are scheduled for the first quarter of 2012.

The new technology involves pumping a Medizone-specific and vapour into a room to completely sterilize everything – including floors, walls, drapes, mattresses, chairs and other surfaces. It is far more effective in killing bacteria than wiping down a room.

Dr. Zoutman says the technique is similar to what we now know Mother Nature uses to kill bacteria in humans. When an antibody attacks a germ, it generates ozone and a minute amount of hydrogen peroxide producing a new highly reactive compound that is profoundly lethal against bacteria, viruses and mold.

"It works well for Mother Nature and is working very well for us," says Dr. Zoutman

There are other disinfecting technologies that involve pumping gas into a room, but Medizone's method is the only one that sterilizes as well as surgical instrument cleaning. It also leaves a pleasant smell and doesn't affect any medical equipment in the room. The entire disinfection process is also faster than other methods – it takes less than one hour.

Dr. Zoutman says the technology could also be used in food preparation areas and processing plants after outbreaks such as listeria and to disinfect cruise ships after an infection outbreak.

But will it kill bugs buried under dirt that standard methods wipe away? I suspect this method requires that a room has a precleaning preparation before the ozone and hydrogen peroxide gets to work.

Good point, there's nothing like good 'ol fashion elbow grease.

You made me think back to when it was discovered that even though hospitals had been sterilizing the tubing used for non-invasive surgical techniques and " other " things, the insides weren't getting clean at all, they subsequently found things like blood and fecal matter in " clean " equipment .

I wonder. I do hope this process is 100 percent effective, because if one deadly little bug survives the treatment, it could be the beginning of the end for all of us.

I have told all bugs of the world to turn on their gene expressions that result in higher tolerance to O3 and H2O2 gas.

Let no bug say I did not warn them. They told me they insist in living with humans, no matter how abominable the before and after conditions.
