Whole blood and component use in resource poor settings

Area of Science:

• Transfusion Medicine
• Public Health
• Hematology

Background:

• Global advancements in blood collection and testing contrast with limited data on blood utilization in developing countries.
• Southeast Asia faces a significant blood deficit, with a demand of 15 million units versus a collection of 9.3 million units.
• Transfusion services in the region exhibit considerable diversity in voluntary blood collection rates and component preparation.

Purpose of the Study:

• To highlight the critical need for improved blood utilization data in developing countries.
• To outline the major transfusion indications and challenges in the Southeast Asian region.
• To discuss the development of blood safety programs and future directions for transfusion services in India and the broader region.

Main Methods:

• Review of existing data on blood collection, testing, and utilization in Southeast Asia.
• Analysis of transfusion indications, including emergency obstetric care, surgery, pediatrics, trauma, and thalassemia.
• Examination of national blood safety programs, policy development, and infrastructure improvements.

Main Results:

• Significant disparities exist in voluntary blood collection (40-100%) and component preparation (10-95%) across the region.
• Thalassemia prevalence necessitates substantial packed red cell transfusions, with India alone requiring 2 million units annually.
• Initiatives like the Indian Blood Safety Program have led to infrastructure development and policy formulation.

Conclusions:

• There is an urgent need for comprehensive data on blood utilization in developing countries to optimize transfusion services.
• Enhancing blood component preparation and establishing national blood policies are vital for meeting regional demands.
• A nationally coordinated transfusion service is envisioned to ensure cost-effective, quality blood products for appropriate clinical use.
