Risk factors and outcomes of hospitalized patients with blood infections caused by multidrug-resistant Acinetobacter baumannii complex in a hospital of Northern China.

The purpose of this study was to determine the risk factors and outcomes of bloodstream infections caused by multidrug-resistant (MDR) Acinetobacter baumannii complex in a hospital of Northern China. Risk factors associated with MDR A baumannii complex included older age, pneumonia, using drainage catheters, and intensive care unit stay. Multivariate analysis showed that multidrug resistance and mechanical ventilation were identified as independent risk factors for 30-day mortality in patients with A baumannii complex bacteremia.
