Clinical Practice Patterns For Hydroxyurea Initiation In Young Children With Sickle Cell Disease

Background: The FDA approved hydroxyurea (HU) for the treatment of sickle cell disease (SCD) in children because it was deemed a safe and efficacious treatment. HU modifies the course of the disease, reduces complications, improves survival, and has few long-term side effects. Despite these benefits, HU uptake remains low for young children. Over 75% of patients who could benefit from HU do not receive the treatment. NHLBI clinical practice guidelines recommend use of shared decision making for HU initiation but currently, there is no “gold standard” for hematology providers to follow when beginning their discussion about HU. Thus, there is likely a gap between care guidelines and clinical practice. A first step in closing this gap is to better understand the current practice utilized by hematology providers when discussing HU as a therapeutic option.
