Microbiological findings in emergency department patients with sepsis identified by the Sepsis-3 criteria: a single-center prospective population-based cohort study.

Patients identified with sepsis by SOFA score were more often blood culture-positive. Gram-positive pathogens, pulmonary tract infections, Streptococcus pneumoniae, and polymicrobial infections were also more common among SOFA patients. Polymicrobial infection, Staphylococcus aureus, and a group of other organisms were independently associated with an increased risk of death.
