Red cell, plasma and albumin transfusion decision triggers

Area of Science:

• Transfusion Medicine
• Clinical Decision-Making
• Hematology

Background:

• Transfusion of blood products is a critical medical intervention.
• Understanding the decision-making process for transfusions is essential for optimizing patient care and resource utilization.

Purpose of the Study:

• To investigate the factors influencing transfusion-related decision-making among medical staff.
• To compare decision-making patterns between different medical professional groups and geographical locations.

Main Methods:

• Hypothetical clinical cases involving red cell, fresh frozen plasma (FFP), and albumin transfusions were presented.
• A questionnaire was administered to 228 medical staff (residents and specialists) in Melbourne and Sydney.
• Transfusion decision triggers were identified and analyzed.

Main Results:

• Red cell transfusion decisions were influenced by hemoglobin levels, anemia symptoms, comorbidities, surgery, gender, hospitalization duration, and blood loss.
• FFP administration depended on coagulation tests, comorbidities, and prior red cell units transfused.
• Albumin administration was linked to hospitalization duration, postoperative urine output, and hypotension.
• Variations in transfusion practices were observed between resident and specialist staff, and between Melbourne and Sydney participants.
• Surgeons were more likely to transfuse than physicians or anesthetists at specific hemoglobin levels.

Conclusions:

• Clinical factors, patient characteristics, and professional roles significantly impact transfusion decisions for red cells, FFP, and albumin.
• Experience level (resident vs. specialist) and geographical location influence transfusion practices.
• Specialized surgical teams exhibit distinct transfusion behaviors compared to medical or anesthesia teams.
