Horizon Hospital germ swabs identify problem areas

Horizon Health unveiled the results of its new cleanliness auditat a board meeting in Miramichi Thursday.

The new information comes on the heels of a CBC News investigation showing some surfaces in high-traffic areas of two hospitals were not wiped clean of an ultra-violet light-reactive gelafter 24 hours, and in some cases, sevendays or more.

The health authority presented percentage data on the results of 2,200organic residue swab audits undertaken since February. The swab tests register a pass or fail, based on how well a surface is disinfected. The test areas, in emergency and inpatient rooms, include commonlytouched surfaces like light switches and bed rails.

Steve Savoie is leading Horizon's staff trainingon the swab tests. He says the data is more useful than simply looking at anareaorsurfaceto see if it appears to be clean.

"We focused initially a lot on what you could see. But this is really focusing on what you cannot see," said Savoie. "Atfirst we had [to] kind of work with our staff and train them to improve the results, and the results are improving quite well now."

Horizon is moving away from gel testing because it shows how effectively a surface was wiped or scrubbed, and not necessarily whether germs are still present afterwards, he said.

"If I clean my [gel] marker with dirty water, I will pass the gel test but fail the [swab]test because I could have bacteria. I could have contaminated my surface with bacteria. So that's why we prefer this, because it's really more in line with what we want to do to ensure that we have a safe environment for our patients."

CBC News applied UV light-reactive gel tosurfaces such as hallway railings,waiting area seating arm rests, and multiple surfaces in washrooms,in hospitals in Fredericton and Saint John. Tests in January and April showedthe vast majority of the surfaces still showed gel after 24 hours, and about half showed gel after sevendays.

Andrea Seymour, vice-president with Horizon, said the investigation prompted the health authority to seek out the surfaces CBC News tested"so that we could go and do our own testing with our [swab]devices and make sure that we are addressing the issues as they arrive."

"It'll take us a little bit of time to make it all the way through our buildings," she said. "And of course it's only point-in-time, so it's really how we sustain what we're doing over time that is really going to make a difference for us."

Seymour said following the CBC News report, germ tests in the emergency areas of the DECH and Saint John Regional passed, but added the audits were not spontaneous.

She said she is encouraged by the newest Horizon audit results.

"Inthose six areas that we are measuring in our patient rooms,which are light switches, door handles, over-bed tables, bed rails, toilets, and sinks in our patient rooms, our performance is really improving and our staff are embracing the new technologies."
