Bloodstream infection with extended-spectrum beta-lactamase-producing Enterobacteriaceae at a tertiary care hospital in New Zealand: risk factors and outcomes

Abstract

OBJECTIVES: To define local risk factors and outcomes for bacteremia with extended-spectrum beta-lactamase-producing Enterobacteriaceae (ESBL-E) at a tertiary hospital in New Zealand. METHODS: Patients with ESBL-E bacteremia were compared to matched control patients with non-ESBL-producing Enterobacteriaceae bacteremia. Patients were matched by onset of bacteremia (community vs. hospital), site of blood culture collection (peripheral vs. via central line), and infecting organism species. RESULTS: Forty-four cases with matched controls were included. Eight- and 30-day mortality was higher in cases than controls (27% vs. 7%; p=0.011 and 34% vs. 11%, p=0.011). Twenty-one cases (48%) were commun..
