Bacteraemic community-acquired pneumonia due to Gram-negative bacteria: incidence, clinical presentation and factors associated with severity during hospital stay

摘要

Background Many studies have evaluated the clinical characteristics of Gram-negative bacteria (GNB) pneumonia. However, in most cases the bacteriological diagnosis is based on unreliable respiratory samples, and research rarely focuses on only bacteraemic patients. The aim of this study was to describe the incidence, clinical characteristics, outcomes, and factors associated with severity during the hospital stay of patients diagnosed with bacteraemic community-acquired pneumonia (CAP) due to GNB.
