How to predict ESBL (part 3)

Six weeks ago I introduced the ESBL-predict study that Tim Deelen from our group coordinates. Every hospital in the world can participate through a user-friendly electronic CRF (in a secured environment). My blog-invitation to particpate worked and some sites already started. In June >1,000 episodes were entered! Here is a short update and info for those that want to join.  Continue reading

HAP: In the ‘too difficult box’?

User:KGH at Wikimedia Commons

I’ve had an enjoyable time at ICPIC. Sessions (abstracts here) have been great, speakers excellent, meeting well-organised but one session rattled my cage. Point prevalence surveys (PPS) and their value was an interesting session, however at the end of it I was wondering whether this was ‘Surveillance in action’ or ‘Surveillance inaction’.

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

LA-MRSA: On the definition of emergence

Some friends, called patriotic hackers, had secured a very interesting surveillance database and I tried to write a manuscript, when I was scooped (in CID) by friends that apparently had access to the same database. That made my work redundant. So, for your eyes only, my take on that data. Continue reading

Looking back to see the post-antibiotic era

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

Staff screening for MDROs: closing Pandora’s Box

A brave study from the Palmore/Frank group at NIH has opened the Pandora’s Box that is screening staff for MDROs, and, I’m delighted to say, firmly closed it with their findings! Only 3% of staff carried ESBLs, one carried a CPE, and none carried VRE, and this despite extensive contact with MDRO patients for many of the staff sampled!

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
