I’ve been struggling for years to find the best ‘catch-all’ term to describe hospital cleaning or disinfection or both. And, after much thought, I’ve settled on a proposal to share with you, dear reader: “environmental hygiene”.
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!
Curtis Donskey’s group recently published a multicentre randomised trial in 16 US hospitals to evaluate the impact of an enhanced cleaning programme (including fluoruescent markers, environmental cultures, and feedback to cleaners) on the transmission of C. difficile. The intervention resulted in an increase in the removal of fluorescent markers, a reduction in environmental contamination with C. difficile, but no reduction in healthcare-associated CDI!
What do you do to prevent VRE transmission?
…you are not alone, if the answer to this question is ‘nothing special’, based on survey published in ARIC! Dale Fisher’s team in Singapore put together a simple survey, asking the global IPC community what measures they have in place to prevent the transmission of VRE. There was a huge degree of variability, ranging from ‘nothing special’ to ‘the kitchen sink’!
See below details of a survey that you may find interesting to complete. I had a small role in providing some feedback on an earlier version of this survey and I hope it will serve to highlight areas that require more thought and / or research…
On behalf of the International Society of Chemotherapy (ISC) working group on Infection Prevention we would be grateful if you could complete this anonymous survey.
A 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
Thought I’d share some key points from the 2016 HIS Spring Meeting.
Outlining the problem(s)
Prof Gary French kicked off the meeting with a (sic) historical perspective, describing how the perceived importance of the environment in transmission has oscillated from important (in the 40s and 40s) to unimportant in the 70s and 80s to important again in the 2000s. Gary cited a report from the American Hospital Association Committee on Infections Within Hospitals from 1974 to prove the point: ‘The occurrence of nosocomial infection has not been related to levels of microbial contamination of air, surfaces and fomites … meaningful standards for permissible levels of such contamination do not exist.’ Gary covered compelling data that contaminated environmental surfaces make an important contribution to the transmission of Gram-positive bacteria and spores, highlighting that C. difficile in particular is a tricky customer, not helped by the fact that many ‘sporicides’ are not sporicidal!
