Study Summary

Despite the well-documented benefits of hydroxyurea (HU) therapy in decreasing morbidity and mortality in youth with Sickle cell disease (SCD), pediatric HU adherence rates range as low as 49% and lead to discontinuation of HU regimens in 8-20%. In addition, treatment non-adherence may lead to unnecessary increases in medication dosage resulting from erroneous assumption that a patient is non-responsive to treatment (versus non-adherent to the regimen as prescribed). Given the detrimental effects of non-adherence, assessment of and intervention for HU non-adherence is essential to improving health outcomes in the pediatric SCD population. Electronic adherence monitoring is widely considered the "gold standard" in objective adherence measurement. These monitors provide continuous, real- time records of medication adherence and reveal problematic behavior patterns, including underdosing, overdosing, delayed dosing, "drug holidays," and "white coat" adherence. Overall, electronic adherence measures are considered valid, reliable, and accurate, with clear advantages over pharmacy refill records, physician estimates and self-report measures. The primary purpose of this pilot study is to determine the use of the AdhereTech as a feasible and valid measure of HU adherence in pediatric SCD. Primary Objective Estimate the association between HU adherence as measured by the AdhereTech device to a) caregiver-report, b) youth-report, c) lab values, d) pill- count, and e) Medication Possession Ratio (MPR) adherence measures Secondary Objectives Estimate the rate of consent to the study, the rate of AdhereTech device use, the rate of AdhereTech device failure, and the perceived acceptability of using the AdhereTech device, as reported by caregivers and youth

Primary Outcome

For each subject, we will calculate the proportion of days of opening the AdhereTech device across the two month study period (days with missing information will not be counted). Caregiver-report of their child's HU adherence will be assessed by the Medical Adherence Measure (MAM), a measure of 7-day self-reported adherence. Each subject's caregiver-reported adherence will be calculated as: \[(medication reported taken \[(medication reported taken ÷ medication prescribed) x 100\]. We will estima
