A nationally representative survey of 100 US healthcare providers managing sickle cell disease patients reveals significant underutilization of red blood cell exchange therapy. The procedure involves removing a patient’s damaged red blood cells and replacing them with donor red blood cells while preserving the patient’s plasma, platelets and white blood cells. Despite widespread availability at 91% of surveyed facilities, fewer than 3% of patients have received this treatment.
Researchers identified multiple barriers preventing broader adoption of the therapy. Healthcare providers cited coordination challenges between medical departments, insufficient donated blood supplies, and limited familiarity with the procedure as primary obstacles. Only 5% of surveyed providers reported experiencing no barriers to administering the treatment. Patients themselves face distinct challenges, including uncertainty about insurance coverage and lack of awareness regarding available treatment options.
Sickle cell disease affects more than 100,000 people across the United States and approximately 8 million worldwide. The condition disproportionately impacts people of color, with 90% of diagnosed patients being non-Hispanic Black or African American and an estimated 3%-9% being Hispanic or Latino. The disease alters hemoglobin function, causing red blood cells to become rigid and crescent-shaped, which can obstruct blood flow throughout the body.
Experts emphasized that expanding access requires systemic changes rather than individual solutions. Approximately 80% of sickle cell patients rely on Medicaid and face socioeconomic vulnerabilities. Geographic limitations also significantly impact care availability, as many patients reside in rural areas served primarily by hospitals lacking specialized equipment and expertise. Medical professionals called for establishing more comprehensive sickle cell disease centers and expanding provider networks to distribute both knowledge and resources more equitably across communities.
