Escherichia coli bacteraemia: how preventable is it?

Mandatory bacteraemia reporting was extended to include Escherichia coli from June 2011. The purpose of this study was to investigate whether the success seen in reducing meticillin-resistant Staphylococcus aureus infection rates could be duplicated with E. coli. All cases of E. coli bacteraemia occurring at our Trust in 2010 were reviewed. There were 216 episodes of E. coli bacteraemia, of which 63% were community-acquired. Only 19% had a potentially preventable cause identified, the majority (71%) of whom had urinary catheter-associated bacteraemia. These data must be kept in mind should targets to reduce E. coli bacteraemia be set in the future.
