Background: Extended-spectrum β-lactamases producing Escherichia coli (ESBL-E) are increasingly identified in health care facilities. As previously done for the control of methicillin-resistant Staphylococcus aureus, many hospitals have established screening strategies for early identification of patients being carriers of ESBL producers in general and ESBL-E in particular, and have implemented contact precautions (CP) for infected and colonized patients.Methods: The incidence of ESBL-E has been compared retrospectively between two French university hospitals (A and B) with different infection control policies over a 5-year long period of time (2006-2010).Results: While hospital A only implemented standard precautions after identification of patients colonized with ESBL-E, hospital B recommended additional CP. During the period of the study, the ESBL-E incidence rate significantly increased in both hospitals, but no significant difference was observed between the two hospitals.Conclusions: This observational study did not reveal that additional CP measures had a greater impact on the incidence of ESBL-E in hospital settings.
