Is extended-spectrum beta-lactamase-producing Escherichia coli rectal carriage at hospital admission predictable? Risk factors at hospital admission.

摘要

I read The production of extended-spectrum (3-lactamases (ESBL) by Enterobacteriaceae is a major health concern. Studies from Spain and other countries have noted that ESBL-producing organisms were isolated from the stool samples of 3.7-5.7% of non-hospitalised patients.1 Whereas risk factors for nosocomial carriage of ESBL-producing Enterobacteriaceae are well known, it is more difficult to identify risk factors for carriage in the community. Studies have reported that 20% of patients with infection due to ESBL-producing Enterobacteriaceae have no identifiable risk factors.1 Identification of carriers is a key step in the prevention of outbreaks. Screening seems to be the cornerstone of control policies, but systematic screening does not appear to be cost-effective.
