Abstract
OBJECTIVE: Adolescents with sickle cell disease (SCD) are at increased risk for complications. Hydroxyurea is a medication that can ameliorate risk but to benefit, adolescents must adhere to treatment. Study aims were to describe how adolescents and their caregivers decided who was responsible for treatment tasks, to describe adolescents' and caregivers' responsibility for these tasks, and to examine if hydroxyurea adherence was associated with younger adolescent age, less discrepancy between adolescents' and caregivers' reports of adolescent responsibility, and higher caregiver involvement. METHODS: Twenty-nine dyads completed treatment responsibility measures. A combination of laboratory and electronic prescription data were used to determine hydroxyurea adherence and electronic medical records were used to determine appointment adherence. RESULTS: Few dyads agreed or planned how to complete treatment tasks. Adolescents shared responsibility with caregivers for medication-taking tasks. Adolescents perceived caregivers and caregivers perceived adolescents were overall responsible for treatment, especially for appointment tasks. Half of adolescents were adherent to hydroxyurea and half were adherent to appointments but medication adherence was not associated with age, discrepancy between adolescents' and caregivers' responses, or caregiver involvement. CONCLUSIONS: Despite frequent hydroxyurea and appointment nonadherence, few adolescents and caregivers plan how to manage adolescents' SCD treatment or perceive they are overall responsible. Future studies are needed to determine the factors that influence these perceptions and if increasing adolescent and caregiver treatment planning improves adherence and clinical outcomes.
