What to do about MDR-GNR? A rapid reflection from ECCMID 2018

There have been a few important updates on the prevention and control of MDR-GNR from ECCMID, here in Madrid. I thought I’d share a couple of key reflections.

Are our attempts to contain CPE going down the drain?

I posted recently on the potential risk of CPE contamination of sinks, drains, and hospital wastewater. The question in my mind then was whether contamination is a smoking gun or innocent bystander regarding CPE transmission? What we really need is an intervention to show that better management of sinks and drains results in reduce CPE transmission. And now, we have one! The findings suggest that attempts to control CPE will go down the drain if we don’t intervene to improvement the management of sinks and drains.

CPE transmission: modes and modulators

I was asked to do a talk today on the modes of CPE transmission at a PHE Workshop on tackling CPE. It caused me to do a lot of thinking and write a new presentation, so I thought I’d share. You can download the slides here.

CPE contamination of hospital wastewater: smoking gun or innocent bystander?

A recent US study has investigated CPE contamination of sinks, drains, and wastewater. Carbapenemase-producing bacteria were identified throughout the drainage and water system, from drains in patient rooms, right through to wastewater sampled through manholes adjacent to the hospital. My main question in all of this is whether this huge reservoir of carbapenemases in hospital wastewater is a risk for patients. The lack of genetic similarity between isolates in hospital wastewater and isolates from patients suggest not, but I suspect there’s an indirect link and these carbapenemases find their way into isolates affecting humans, which is supported by genetic links between the plasmids carrying the carbapenemases.

CPE guidelines galore: ECDC and ACSQH join the party

I recently posted on the WHO CPE guidelines. A couple of people have alerted me to two other recently published guidelines, one from ECDC, and the other from Australian Commission  on Safety and Quality in Healthcare. So, we now have a wealth of guidelines to prevent and control CPE. But how to they compare?

CPE screening Q&A: the who, when, and how

I gave a talk yesterday as part of a PHE London event on the whys and wherefores of screening for MDROs – my talk was focussed on CPE, and you can download my slides here: “CPE: seek and ye shall find”. I thought a quick Q&A would be the best way to summarise the content.

Special issue on MDR-GNR

The Journal of Hospital Infection have published a welcome special issue on multidrug-resistant Gram-negative bacteria. The collection includes some updates on epidemiology, staff carriage (again!), clinical microbiology, and patient perspectives on CPE, and is well worth a read.
