    Abstract:
    The aim of this study was to assess the value of surveillance cultures in identifying extended-spectrum beta-lactamase-producing Enterobacteriaceae (ESBL) carriers upon admission to hospital, and to identify risk factors for carriage. This prospective cross-sectional study included all hospital admissions over one week. Of 525 patients screened, 56 were positive for ESBLs. Half were only identified through screening. Four independent risk factors were identified: nursing home residency, hospitalization in the previous year, prior antibiotic treatment and prior ESBL carriage. Over 50% of the screened patients had at least one risk factor. By screening this targeted population, 87.5% of positive patients would have been identified.
