Clinicians are encouraged to adopt the principles of patient blood management (PBM) and related evidence-based guidelines to determine the appropriateness of transfusion.
PBM is a coordinated healthcare approach to patient care that focuses on strategies to reduce or avoid the need for a blood transfusion where possible, alongside the appropriate use of blood.
General principles of blood component therapy include:
- The decision to transfuse should:
- be based on an appropriate clinical and laboratory diagnosis
- consider the risks and benefits to the patient, and
- consider the availability, cost, and the importance of appropriately using a valuable, freely given community resource.
- Transfusion can effectively and efficiently provide or replace missing or malfunctioning elements of the blood or immune systems.
- Transfusion therapy can provide short or long-term support.
Informed consent should be obtained and documented for all transfusions of blood components in accordance with national standards and guidelines, and local institutional informed consent policies.
