According to a study published by Allison Ashley-Koch, Quanhe Yang, and Richard S. Olney of the Centers for Disease Control and Prevention ("CDC"), Sickle Cell Disease is a major public health concern. Each year in the US, an average of 75,000 hospitalizations are due to Sickle Cell Disease, costing approximately $475 million. The average length of stay per hospital visit was 6.1 days and adults tended to have longer stays than children and adolescents.
