  1. qSOFA scores were assessed with the most abnormal vital signs taken during the 24-h period before the ICU admission
  2. Bloodstream infection was defined as blood culture-positive infection including infective endocarditis, bacteremia from an unknown origin and catheter-related bacteremia
  3. ICU intensive care unit, NA not applicable, qSOFA quick Sequential Organ Failure Assessment
