Since writing this 2015 review on gaps and controversies in the guidelines for the prevention and control of CPE (and other MDR-GNR) I’ve tried to keep it fairly up to date. So, here’s the latest iteration, including the 2015 CDC guidelines.
I blogged recently about the new ESCMID guidelines on resistant Gram-negative carriage and decolonisation, which supported a “once positive, always positive” approach to CPE carriers due to the lack of effective decolonisation options. A new study suggests that a large majority (75%) of patients who were once identified as CPE carriers no longer had CPE detectable when they were readmitted. This has implications for the management of CPE carriers in hospitals.
I’ve spent the last couple of days up in Liverpool for Infection Prevention 2019. One of the highlights was a talk by Dr Paz Aranega-Bou on the issues around contamination of sinks and drains. Paz flagged a paper just published in JHI investigating the dispersal of CPE in a sink/drain test risk at PHE, showing the CPE can make its way from contaminated drains to sink and surrounding surfaces via splashback.
We have blogged a fair bit recently about the risk of antibiotic-resistant Gram-negative bacterial contamination of sinks and drains. A new study offers a novel approach to this problem: by repurposing a balloon catheter to extend the duration of contact between a disinfectant and the sink-end of the pipe.
A fascinating study from a European research group has unravelled the molecular epidemiology of a large European collection of carbapenem-resistant Klebsiella pneumoniae clinical isolates. Most carbapenem resistance was due to an acquired carbapenemases, transmission clusters were common within and between hospitals, carbapenemase-producing isolates are more likely to spread in hospitals, and 21 SNPs is the magic number for defining CPE person-to-person transmission using WGS.
