Now online in Lancet ID an impressive and important retrospective study describing the faith of 437 patients with BSI caused by carbapenamase-producing Enterobacteriaceae (CPE). When scanning the conclusions of your weekly diarrhea of new papers (as I do) this one might have escaped your attention: (in short) “Appropriate therapy is good. Combination therapy too. Patients with BSIs due to CPE should receive active therapy.” Yet, there is much more interesting stuff in this paper. Continue reading

How to predict ESBL BSI (part 2)
A month ago (April 11) I blogged on the difficulties in predicting the presence of ESBL-producing bacteria as a cause of infection at the time antibiotics must be started. Wouter Rottier (PhD student) developed 2 prediction rules (for community-onset and hospital-onset infection), that seem to do better than current guideline recommendations (especially for reducing unnecessary carbapenem use). Another PhD student (Tim Deelen) now wants to validate these rules, globally. The “crowd-funding study approach” worked and sites across the world joined us…. Continue reading
Can we halve Gram-negative BSIs by 50% by 2021? The crowd say “No”
Most of those casting their vote supported Martin’s (somewhat pessimistic) view that we can’t halve Gram-negative BSI by 2021 (see the figure, below). Let me first give you my own, unspoiled opinion (written before the results of this survey were known). I was intending to vote for option 3 (the English can’t, the Dutch might) but I am not even sure of that; actually, I believe that neither the English nor the Dutch can.
Going for GNBSI
We’ll be publishing the results of the vote on whether or not we can halve HA-GNBSI by 2021 later this week. Right now, it looks like Martin is heading for a comfortable, if somewhat depressing victory (“No, we can’t halve GNBSI by 2021”) but there’s still time to ride a wave of positivity and vote with me that “Yes, we can halve GNBSI by 2021”. So, I thought that now would be an appropriate time to review the recent JHI paper that both Martin and I referred to, providing some enhanced epidemiological data on E. coli BSIs in England.
Can we really halve Gram-negative BSIs (GNBSIs) by 2021? Kiernan vs. Otter Mk II
The UK government has recently announced their ambition to halve the rate of Gram-negative BSIs by 2021. Looking at the latest mandatory reporting dataset (see Figure 1 below), you can see why. Impressive reductions in MRSA BSI and C. difficile, but a notable increase in E. coli BSI. And this combined this with worrying data around increased antimicrobial resistance in Gram-negative bacteria from the ESPAUR report. In this post, Martin Kiernan and Jon Otter present both sides of the argument as to whether Gram-negative BSIs can be reduced by 2021, with comment from Andreas Voss and Marc Bonten! And you get to vote on which side of the argument you come down on after reading the arguments. Let battle commence…
Colistin resistance and mortality
My previous blog on “mcr-1 and the end of the world” evoked responses on the important effects of colistin resistance on patient outcome, referring to a new study in CID with the following abstract closure: “Importantly, mortality was increased in patients with colistin-resistant isolates.” The wording is correct, but I’m afraid that it will be interpreted incorrectly. Continue reading
Mcr-1 and the end of the world
If you read this, you may well be concerned about antibiotic resistance and consider reducing the burden of disease caused by AMR as one of your professional goals. Broad attention helps us to fight the problem: it creates awareness and funds for research. So, how do we cope with data that may jeopardize these ambitions (raising awareness fort he problem AMR)? Here is the eaxmple of mcr-1. Continue reading
Halving GNBSI
The Department of Health announced last week their intention to halve the rate of E. coli BSI by 2020. Whilst this is a move that should be embraced, it will be an enormous challenge to achieve. The reduction that has been delivered with MRSA BSI could be seen as a model for success (and I suspect that if you were a politician, you would see it this way). However, it is vital to recognise that E. coli BSI and, more broadly, Gram-negative BSI (GNBSI) are not the same as MRSA BSI, and will require a different reduction strategy.
CPE Thrill-seeking
Yesterday I attended a meeting at the Wellcome headquarters in the middle of London. I deliberately exposed myself to several risks: by car from home to Schiphol, by plane to London City and by public transport to the meeting. Each transition harbors a quantifiable risk of ending up in a hospital (accidents, assaults, cardiac events) where there is a quantifiable risk of developing HAI, and I am especially afraid of CPE.
I see a GNBSI reduction target on the horizon…
I have finally got around to reading the UK Government response to the AMR Review, which includes some interesting details about aspirations to reduce Gram-negative BSIs (GNBSI) and antibacterial agent usage in human and animal health.
