Agent Orange in spinal surgery

This week I learned from an orthopaedic surgeon that randomized trials were something that could be of use in “pharmaceutical sciences”, but that it is well-known that in the “surgical science” retrospective analyses are better for deriving evidence. We came to this when discussing the benefits of powdered vancomycin in the wounds of spinal surgery. Apparently this is something “all spinal orthopaedics do”, because it works so good.

Exposed: Dutch clinical microbiologists

Exposed; that’s what we are. We, Dutch clinical microbiologists. Globally acknowledged for our capacity to control antibiotic resistance, prevent hospital-acquired infections (HAI) and practice the most rational and restrictive antibiotic policies. That we are self-confident, loud and arrogant  is taken for granted, as most do with Christiano Ronaldo. But it is with great sadness that I have to announce that it was all FAKE. The balloon was pricked by professor Marcel Levi. Continue reading

Real-time whole genome sequencing (RT-WGS) & spread of resistant bacteria

At last weeks’ ICPIC I crossed arguments with John Rossen on the question whether RT-WGS helps us to control the spread of resistant bacteria. The setting is the hospital and the definition of RT is “in time to guide essential decision making”. Is RT-WGS a “need-to-have” or a “nice-to-have” thing? Continue reading

The rocket-science of a CPE screen & isolate policy

Last weeks’ blog from Jon Otter on the practice of CPE screening and isolation raised some interesting comments (on twitter) emphasizing the difficulties in policy making for infection control. The two comments that struck me were: (1) … screening for CPE sounds logical “but does it work in long-term care facilities with high-levels of endemicity?” And “I use it in my hospital, but face difficulties in convincing others because of lacking scientific evidence for CPE.” Continue reading

WHO IPC Core Components

While I had seen the WHO IPC Core Components, I have totally missed the great video they made.  Thus, with no further comment, here the link to this well-made video.

Candida auris part III. Are you prepared?

Schermafbeelding 2017-05-20 om 13.28.23

MMWR just published on the ongoing transmission of Candida auris in the US, while at the same time PLOS Pathogens came with an excellent review on the topic.

By now I had the debatable pleasure to be around for the birth of a few “superbugs”, but this one is clearly putting a lot of effort into reaching the top of the list. I believe (classical pessimist) that many institutions still ignore this new adversary (or are even unaware), and most certainly have no game-plan to prevent its introduction and consequent spread.  In the MMWR publication the current recommendations for C. auris–colonized or infected patients were repeated, with only one change from previous recommendations, namely that a more effective (sporicidal) disinfectant is needed, but I seriously wonder who follows this guidance.

Thus, here it comes, another 30-seconds-questionaire.  Why?  Because I hope that you will prove me wrong and that we – the infection control people at the frontline – act on threat, instead of re-act once we are overrun.

Fluoroquinolone use and C. difficile infections: The English miracle not yet explained?

A few weeks ago in LID this marvellous paper, clearly demonstrated the reduction of fluoroquinolone-resistant but not fluoroquinolone-susceptible C. diff infections (CDI) in English hospitals, coined as “the English C. diff miracle”. The CDI decline coincided with the reduction of fluoroquinolone use, but also with a period in which “horizontal” infection control measures, such as hand hygiene, were improved. As the latter would be equally effective in preventing transmission of resistant and susceptible strains, the fluoroquinolone reduction was considered causative for the observed reduction. A very simple model tells us that that is not necessarily the case. Continue reading
