Should we disinfect the loo BEFORE flushing?

There is a risk that an infectious aerosol is produced when toilets are flushed. One way of addressing this would be to add a disinfectant to the toilet before flushing. But would this be safe and effective?

Painting the hospital room blue

This recent study from the Donskey group could provide hospital cleaning staff with a powerful visual cue to help assure adequate disinfectant coverage. The addition of a chemical widget to bleach solution gives it a bright blue hue when applied to surfaces, so allowing a cleaner to track their progress visually!

Agent Orange in spinal surgery

This week I learned from an orthopaedic surgeon that randomized trials were something that could be of use in “pharmaceutical sciences”, but that it is well-known that in the “surgical science” retrospective analyses are better for deriving evidence. We came to this when discussing the benefits of powdered vancomycin in the wounds of spinal surgery. Apparently this is something “all spinal orthopaedics do”, because it works so good.

Time to go shopping for a UVC system?

It is great to see the long-awaited ‘Benefits of Terminal Room Disinfection’ (BETR-D) randomised controlled trial of a UVC automated room decon (ARD) system published, in the Lancet, no less! This study firms up the importance of environmental contamination in transmission, and demonstrates additional benefit of UVC over and above enhanced conventional methods for VRE, maybe for MRSA, but not for C. difficile.

Attacking the fecal veneer*

What an excellent start of 2017. A great study from the USA today in Lancet: In a pragmatic cluster-randomized crossover study they tested 4 patient room cleaning strategies on the effectiveness to reduce acquisition with relevant bacteria for the incoming patients. The conclusion states that “enhanced terminal room disinfection decreases the risk of pathogen acquisition.” Yet, this paper is so “data-dense” that you must read the methods (and supplements) to get the picture. In one shot: Not for C. diff, may be for MRSA and yes for VRE. Continue reading

Breaking the chain of infection – hygiene is everyone’s responsibility

ifh-chain

As International Infection Prevention Week (#IIPW) continues, Prof Sally Bloomfield writes a guest blog on the principles of breaking the chain of infection. Whilst the blog is focused on home and everyday life settings, the principles are relevant to healthcare facilities too!

This is international Infection Prevention Week. To address this year’s theme “Breaking the Chain of Infection” the International Scientific Forum on Home Hygiene (IFH) has produced a simple online resource Breaking the Chain of Infection.

Back to the floor..

flooringA little while ago I blogged about the excellent study from Nottingham that demonstrated significant VRE and MRSA contamination on socks used to prevent falls in the hospitalised elderly. This has been followed by another paper suggesting that shoe coverings undurprisingly become contaminated. So, what? How does this really impact on transmission? A new study from Curtis Donskey’s group has looked at hand contamination in patients directly relating to floor contamination. Continue reading
