Global Treatment Satisfaction Levels And Treatment Patterns From The International Sickle Cell World Assessment Survey (Sway): Hydroxyurea (Hu) Versus No Hu

Background: SWAY was a cross-sectional survey that assessed the global impact and treatment of sickle cell disease (SCD) (James et al. ASH 2019). SCD puts patients at risk of multiple complications driven by vaso-occlusion and hemolytic anemia. Vaso-occlusive crises (VOCs) are the hallmark of SCD and can require healthcare attention. VOC frequency may be reduced by HU (Charache et al. N Engl J Med 1995).
