Predominance of healthcare-associated cases among episodes of community-onset bacteraemia due to extended-spectrum β-lactamase-producing Enterobacteriaceae

•True community-acquired (CA) ESBL-PE bacteraemia is rare.•CA ESBL-PE bacteraemia was identified in only 3.2% of patients.•Major risk factor for community-onset ESBL-PE infection is prior hospital stay ≥5 days in previous year.•Appropriate empirical regimen was administered within 24 h in 45% of ESBL-PE bacteraemia patients.•Patients with CA ESBL-PE bacteraemia had a comparable outcome to those without ESBL-PE infection.
