We have blogged a fair bit recently about the risk of antibiotic-resistant Gram-negative bacterial contamination of sinks and drains. A new study offers a novel approach to this problem: by repurposing a balloon catheter to extend the duration of contact between a disinfectant and the sink-end of the pipe.
A fascinating study from a European research group has unravelled the molecular epidemiology of a large European collection of carbapenem-resistant Klebsiella pneumoniae clinical isolates. Most carbapenem resistance was due to an acquired carbapenemases, transmission clusters were common within and between hospitals, carbapenemase-producing isolates are more likely to spread in hospitals, and 21 SNPs is the magic number for defining CPE person-to-person transmission using WGS.
I attended a brilliant seminar at Imperial College last week on the role of machine learning and artificial intelligence (AI) in infectious management, and to a lesser extent, infection prevention and control. There’s so much potential for this exciting technology to revolutionise the way we identify, treat, and prevent the spread of infectious diseases. But, there’s also some risks – some are already asking whether the robots are taking over, and whether that is an entirely good thing!
We tend to find that the flu season in Australia is an early predictor for the severity of the coming flu season in the Europe. And the early indications are the flu in Aus this year is bad – unprecedentedly bad. So, let’s get our flu vaccination campaign planning hats on!
I participated in Imperial College London’s school outreach programme by doing an intro to infectious disease epidemiology with a group of year 10-12 students (age 15-18) (you can download my slides here). It was hugely rewarding and highly recommended for anybody considering supporting this sort of work. The group were sharp, good fun, and asked good questions – and perhaps included one of the next generation of infectious disease epidemiologists?
I love and hate SSI prevention in equal measure. On the one hand, we have good evidence and strong guidelines around SSI prevention – but on the other hand, implementing these interventions to prevent SSI can be enormously tricky in practice. One key factor in preventing SSI is creating a well-closed wound in theatre. Surprisingly, there’s precious little data on how to measure what a well-closed surgical wound looks like. This qualitative study presents some potential indicators to measure good surgical wound closure in order to prevent SSI.
