Risk of infection from Blood transfusions

  • We are already moving to decreasing transfusions in general for most of our hospital patients
  • But now there is evidence that more transfusions can lead to an increase in nosocomial infections

JAMA Meta-Analysis

  • 18 randomized trials with 7,593 patients
  • All tested higher vs lower transfusion thresholds in a variety of inpatient settings
  • Hospital-acquired infections were the outcome

What they found

  • Absolute risk for nosocomial infection was 17% among patients with a higher hemoglobin target compared to 12% with a lower target
  • NNT to avoid an infection was 38 using a restrictive transfusion strategy

Bottom Line

  • Potential cost savings to the healthcare industry with less transfusions
  • For most patients, a hemoglobin > 7 g/dL is just fine
