Transfusion practices and complications in thalassemia

Area of Science:

• Hematology
• Transfusion Medicine
• Genetics

Background:

• Severe thalassemia forms are common inherited anemias requiring regular blood transfusions.
• Current transfusion policies and complication management lack standardization, impacting patient quality of life and survival.

Purpose of the Study:

• To assess current transfusion practices, complications, and educational needs in thalassemia care across multiple US centers.
• To identify gaps in care and inform the development of standardized treatment protocols.

Main Methods:

• A survey of 58 items was administered to 11 centers in the Western US in 2016.
• Data collected included patient demographics, transfusion practices, complications, and perceived educational needs for 717 patients with alpha or beta-thalassemia.

Main Results:

• One-third of patients were transfusion-dependent; practices varied significantly between centers.
• While leukoreduction and Rh/Kell matching were common, alloantibody management was inconsistent.
• Iron overload was identified as a major challenge, with diverse chelation strategies.

Conclusions:

• The US thalassemia population is likely underestimated, as many patients receive care outside major national centers.
• A lack of evidence-based guidelines hinders optimal care.
• Regional consortia are recommended to establish standardized care and address educational needs.
