Many guidelines now recommend screening some patients on admission for carriage of CPE. However, very few cost-effectiveness analyses have been performed. A Canadian group have just published a modelling study with a tantalising conclusion: universal admission screening for CPE is likely to be cost-effective, and may even be cost-saving!
The PHE Toolkit recommends pre-emptive isolation for patients who meet one of the risk-factor triggers for CPE screening. Furthermore, the pre-emptive isolation recommended in the Toolkit should be continued until three negative screens are obtained, each separated by 48 hours. In what is best described as a data-based thought experiment, colleagues from Imperial tested the impact of various CPE screening strategies on the burden of contact precautions generated.
