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

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

Up-date on M. chimaera

More and more reports and guidance (Ref) appear with regard to Mycobacterial infections associated with heater cooler units used during thoracic surgery. As mentioned in this blog before, the infections are attributed to aerosol generated by the contaminated heater cooler units that are located in or adjacent to the operating room (Ref).

Just now, researchers published 10 patients with disseminated Mycobacterium chimaera infections subsequent to open-heart surgery at three (CH, GER, NL) European Hospitals (Eur Heart J. 2015 Jul 17).

What makes this infections special, is the fact that the time to infection may takes months to years and that the micro-organism in question is easily missed by routine bacterial diagnostics.

The word is out, that other, difficult to diagnose micro-organisms e.g. Legionella are possibly causing post-operative infections, too. Thus, I believe that we can expect more cases with different pathogens in the near future.
