Summary

Blood transfusion risks are decreasing due to better testing and safety measures, but a zero-risk supply remains impossible. Infectious and noninfectious complications, though rare, still pose challenges in transfusion medicine.

Area of Science:

  • Transfusion Medicine
  • Hematology
  • Public Health

Background:

  • Blood transfusion safety has significantly improved over the last decade.
  • Advances include enhanced blood testing, viral inactivation, donor screening, and transfusion alternatives.
  • Despite progress, achieving a zero-risk blood supply is not feasible.

Purpose of the Study:

  • To review the current landscape of blood transfusion-associated complications.
  • To highlight both infectious and noninfectious risks.
  • To discuss the evolving safety of blood products.

Main Methods:

  • Review of current literature and safety data in transfusion medicine.
  • Analysis of reported transfusion-associated complications.
  • Assessment of the impact of implemented safety strategies.

Main Results:

  • Infectious risks, particularly from hepatitis viruses and human immunodeficiency virus (HIV), are a public concern.
  • HIV transmission via transfusion is rare in the US (<20 cases/year).
  • Key noninfectious risks include alloimmunization, immunosuppression, and graft-versus-host disease.

Conclusions:

  • While transfusion risks have been substantially mitigated, they cannot be entirely eliminated.
  • Ongoing vigilance and research are necessary to further enhance blood product safety.
  • Understanding the spectrum of risks is crucial for clinical decision-making and patient safety.
