Blood Stream Infections in Burns: A 14-Year Cohort Analysis

Abstract

Background: Blood stream infections are a significant cause of morbidity and mortality in burns, and pathogen identification is important for treatment. This study aims to characterize the microbiology of these infections and the association between the infecting pathogen and the hospitalization course. Methods: We conducted a cohort study that included records of burn patients treated at the Soroka University Medical Center between 2007–2020. Statistical analysis of demographic and clinical data was performed to explore relationships between burn characteristics and outcomes. Patients with positive blood cultures were divided into four groups: Gram-positive, Gram-negative, mixed-bacterial, and fungal. Results: Of the 2029 burn patients hospitalized, 11.7% had positive blood cultures. The most common pathogens were Candida and Pseudomonas. We found significant differences in ICU admission, need for surgery, and mortality between the infected and non-infected groups (p p p p < 0.001). Conclusions: Anticipating specific pathogens which are associated with certain burn characteristics may help guide future therapy.
