The Department of Health have published a new 5 year National Action Plan to combat AMR (2019-2024) to follow on from the 2013-2018 edition. IPC and antimicrobial stewardship are high on the agenda – but we have a long way to go if we are to fulfil the 20 year vision for AMR: ‘By 2040, our vision is of a world in which antimicrobial resistance is effectively contained, controlled and mitigated.’

For many years, “5 log reduction” (LR) has been the gold standard for disinfectant efficacy despite absence of dose:response data linking it to clinical outcomes. The family of EN tests now used to support claims for disinfectant products has its origins in the European Suspension Test (5LR, 5 mins, 5 test organisms) where 5 LR was probably chosen because it is the limit of sensitivity in an assay where, traditionally, the initial bioburden is 108 colony forming units. For soap, detergent or dry wiping procedures, until recently their effectiveness has been assumed – possibly on the basis that they produce visible cleanliness? It is only recently that we have had access to efficacy data based on lab models. A trial of EN 1699 handwashing test showed a mean 2.76 LR when hands contaminated with E .coli are washed with soap.
I attended a thought-provoking session at the recent Healthcare Infection Society (HIS) conference in Liverpool on reducing GNBSI (you can download some of the speaker abstracts here). It seems that the hefty majority of E. coli BSIs are rooted in issues outwith the walls of acute hospitals. So the question is, who’s going to tackle these issues to prevent GNBSI? Who’s going to go for GNBSI (sorry, couldn’t resist another pop-culture reference to the ‘80s – who could forget ‘Going for Gold’ with Henry Kelly).
There are pros and cons of increasing the proportion of single rooms. One of the commonly-cited pros is a reduction in HCAI. A recent UK study provides some evidence that C. difficlie infection, and MSSA / E. coli BSIs are not reduced by a move to a hospital with more single rooms, but that norovirus control is more effective when you have more single rooms.
I am on the hunt for some free online training resources for HCAI / IPC / AMR / AMS / IPC, at a basic, intermediate, or advanced level. Here’s a summary of what I’ve unearthed so far.
A study just published in ICHE investigates tweeting activity at several IPC / ID / AMR conferences (the 2016 editions of IPS, ID Week, FIS/HIS, and ACIPC). Perhaps the most interesting finding is that including a weblink or tweeting on certain topics (including C. difficile and the media) increase the chances of a tweet being retweeted, whereas, surprisingly, including a picture reduces the changes of a tweet being retweeted.
ICHE recently published an unusual article (which other article has ‘the world wide web’ as their setting) on blogging in ID and clinical micro. The article reviewed around 100 blogs and rated them using a multifaceted tool. The article has some useful qualitative feedback from bloggers and readers, and identifies some gaps in the blogosphere (especially around antimicrobial stewardship). Rachael Troughton, one of the study authors, recently published a post on the article – and here’s my take on it.
