BMC Medicine has published some research from our group reporting the findings of a mathematical model comparing various approaches to screening for CPE carriage. The model compared how several operational metrics varied with different approaches to screening (‘slow and cheap’ laboratory culture vs. ‘fast and expensive’ PCR) and in various specialties with variable levels of compliance with CPE admission screening and at various levels of admission prevalence of CPE. The main conclusion was that culture proved to be the best approach in most scenarios, balancing risk and resource.
