A new paper by Hopman and colleagues (Andreas is also another author but is being modest) has evaluated the effect of removing sinks from the ICU. The trigger for this intervention was an outbreak caused by an ESBL-Enterobacter that could be related to contaminated sinks. The study looked at what happens if you remove all water sources from the ICU, and all water-related activities were migrated to a tap water-free solution. Continue reading
Tabloids have repeatedly warned the people for superbugs on chicken meat, after researchers had convincingly shown that the chicken filets that we buy are contaminated with ESBL-producing bacteria, mainly E. coli. Widely considered a public health threat, it was a decisive argument to insist on reductions in antibiotic use in the agricultural industry in the Netherlands. Yet, whether meat contamination constitutes a risk for human health is unknown. This was now quantified, with surprising results. Continue reading
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
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
I gave a webinar last week for 3M (you can download my slides here) on “Your hospital room can make you sick: How improved cleaning and disinfection can help”. I asked the audience what they were doing to improve cleaning and disinfection, and thought I would share the findings. I don’t know the exact size of the audience (but it’s usually a couple of hundred mainly US based IPC folks), and the audience were allowed to choose any answers that applied to them for the second two questions.
We often see those tasked with finding suitable isolation facilities counting down to when precaustions can be discontinued and the ’48 hours clear’ of symptoms of loose stools or vomiting has almost become one of the most welcome statements heard in healthcare settings. No more contact precautions, no more disinfectants sloshing around, normality beckons.. Or should it? Continue reading
Anybody doubting that biofilms really do exist on dry hospital surfaces needs to read this study: biofilms are there, they are complex, and they are common. A landmark study by the same Australian Vickery group published in 2012 first identified biofilms on a handful of dry hospital surfaces in an ICU. But this study is far more comprehensive and convincing.
