Hydroxyurea Adherence for Personal Best in Sickle Cell Treatment: HABIT

CHWs will have scheduled interactions with subjects at home, by telephone or at Community League of the Heights (CLOTH), our partner community-based organization (CBO). CHWs will customize text messaging jointly with each youth and parent (Month 3) and text message reminders to both parent and youth will be implemented during Months 4-6. Subjects lacking a mobile phone or sufficient cell phone plan will be compensated to purchase or upgrade plans to accommodate texts.

Dyads randomized to the control group will continue usual clinic-based care, including monitoring and review of HbF levels, and similar frequency of clinic visits and access to sickle cell team staff. They will be provided with educational materials about sickle cell disease and hydroxyurea use for children.
