Risk Factors and Outcome of Pseudomonas Aeruginosa Bloodstream Infections (PABSI) in Hematological Patients: A Single Center Retrospective Cohort Study

Bloodstream infections caused by Pseudomonas aeruginosa (PABSI) in hematological patients are associated with high morbidity and mortality. We investigated the epidemiology, risk factors, and outcomes of PABSI at our center. All adult hematological patients with PABSI between January 2013 and July 2023 were included. Demographic and clinical characteristics, antimicrobial susceptibilities, antibiotic therapy, fluoroquinolone-prophylaxis, source of infection, and 30-day outcome were recorded. Descriptive statistics, tests for difference, and logistic regression models were performed. Fifty patients with PABSI were identified with a median age of 58.5 years (range 24–78). 37 patients (74
