Abstract

To compare the early and late predictive value of several critical illness scores (CISs) and biomarkers in patients with bloodstream infection (BSI)-associated pneumonia, and to identify the value of procalcitonin (PCT) in etiological diagnosis. Patients with at least one positive blood culture within 24 hours admission to department of emergency of China-Japan Friendship Hospital from January 2014 to December 2018 and with final diagnosis of pneumonia were enrolled. Sequential organ failure assessment (SOFA), mortality in emergency department sepsis (MEDS), Logistic organ dysfunction system (LODS), and acute physiology and chronic health evaluation II (APACHE II) scores were calculated based on the first parameters on the day of admission. Differences of various indicators among different Gram-stained bacterial infections and among patients with different prognosis at 28-day or 60-day were compared. Receiver operating characteristic (ROC) curve was used to analyze the value of biomarkers in differential diagnosis of pneumonia caused by single bacterial infection, and the predictive value of several CISs and biomarkers on 28-day and 60-day death of patients with pneumonia. Among 540 patients with pneumonia caused by single bact...Continue Reading
