[Variations in transfusion practice in Spain]

Area of Science:

• Hematology
• Transfusion Medicine
• Public Health

Context:

• Significant regional and hospital-level variations exist in blood component transfusion practices within Spain.
• Understanding these variations is crucial for optimizing blood resource management and patient care.

Purpose:

• To analyze geographical and institutional variations in erythrocyte, platelet, and plasma transfusion rates in Spain.
• To investigate the correlation between blood donation rates and transfusion rates across different administrative and healthcare levels.

Summary:

• The study reveals substantial variability in transfusion practices across Spanish regions, provinces, and hospitals, with platelet transfusions showing the highest variation.
• Blood donation rates demonstrated a strong positive correlation with erythrocyte and platelet transfusion rates, but not plasma transfusion rates.

Impact:

• Highlights disparities in transfusion medicine utilization across Spain, necessitating targeted interventions.
• Provides evidence for the link between blood supply and demand, informing blood collection strategies and transfusion policies.
