To transfuse, or not to transfuse: that is the question

Area of Science:

• Transfusion Medicine
• Clinical Outcomes Research
• Critical Care Medicine

Background:

• Transfusion practice has evolved significantly, mirroring broader medical advancements.
• Emerging evidence links blood transfusions to adverse outcomes in various clinical settings.
• Patient populations studied include critically ill, trauma, cardiac surgery, acute coronary syndromes, and oncology patients.

Purpose of the Study:

• To highlight the existing gaps in the literature guiding clinical transfusion practices.
• To advocate for a dedicated Australasian study to address these evidence deficits.

Main Methods:

• Review of current clinical outcomes research on blood transfusion impacts.
• Identification of limitations and deficits in existing transfusion guidelines and evidence.
• Proposal for a large-scale, Australasian-focused clinical study.

Main Results:

• Mounting evidence indicates potential adverse outcomes associated with blood transfusions.
• Significant deficits exist in the literature guiding optimal transfusion practices.
• Current evidence is insufficient to provide definitive guidance across all patient cohorts.

Conclusions:

• Adverse effects of blood transfusion necessitate a re-evaluation of current practices.
• An urgent need exists for robust, context-specific research.
• A coordinated Australasian study is proposed to fill critical knowledge gaps in transfusion medicine.
