The primary objective of this study is to better understand factors contributing to variations in hydroxyurea (HU) adherence behavior in adolescents and young adults (AYA) with sickle cell disease (SCD). To meet this objective, the researchers will conduct a prospective cohort study to determine the longitudinal relationship between HU adherence and health-related quality of life (HRQOL) overtime among AYA with SCD. The long-term goal of this research is to promote medication adherence behavior and improve health outcomes in AYA with SCD.
Sickle cell disease is the most common genetic disorder in the US, affecting about 100,000 Americans, and about 1 in 400 African American live births, incurring annual health care costs of $335 million. SCD can lead to serious complications including unpredictable, debilitating pain episodes, cardiopulmonary disease, stroke, and long-term end organ damage.These complications lead to significant declines in health-related quality of life (HRQOL) and other patient-reported outcomes (PROs), culminating in early mortality, particularly among AYA. Hydroxyurea, at present, is the main FDA approved medication for SCD that reduces morbidity and mortality, improves HRQoL and lowers healthcare utilization.However, adherence to HU remains suboptimal with only 35-50% of patients achieving high adherence (≥90%), particularly among AYA with SCD. Low HU adherence has been associated with worse health outcomes, poor HRQOL and increased healthcare utilization. Low HU adherence is multifactorial, especially in AYA with other competing priorities and vulnerability in developmental and psychological factors contributing to adherence behavior. The specific aim for this study is to determine the longitudinal relationship of HU adherence behavior to health-related quality of life, barriers to adherence and habit formation among AYA with SCD.

A novel multifunctional mobile app (HU-Go) to improve adherence to hydroxyurea in patients with sickle cell disease
Ann & Robert H Lurie Children's Hospital of Chicago
Chicago, Illinois, United States
Hydroxyurea adherence rate
Adherence rate is defined as number of given HU doses given, as captured by HU-Go app, divided by total number of doses expected during study period.
Time frame: 12 months
Adherence to Hydroxyurea using PROMIS Medication Adherence Scale (PMAS)
Higher score indicating higher adherence to hydroxyurea
Time frame: 12 months
Adherence to Hydroxyurea using Visual Analogue Scale
Numerical value on a scale 0-100% (higher score indicating higher adherence to hydroxyurea)
Time frame: 12 months
Pain score using Patient reported outcomes measurement information system (PROMIS) measure
Patient reported outcomes measurement information system (PROMIS) measure for pain intensity, numerical value on a scale of 0-100 points, normal average for the general population is 50 with standard deviation of 10 points (higher T scores indicating worse pain).
Time frame: 12 months
Fatigue score using Patient reported outcomes measurement information system (PROMIS) measure
Patient reported outcomes measurement information system (PROMIS) measure for fatigue, numerical value on a scale of 0-100 points, normal average for the general population is 50 with standard deviation of 10 points (higher T scores indicating worse fatigue).
Time frame: 12 months
Physical function score using Patient reported outcomes measurement information system (PROMIS) measure
Patient reported outcomes measurement information system (PROMIS) measure for physical function, numerical value on a scale of 0-100 points, normal average for the general population is 50 with standard deviation of 10 points (lower T scores indicating worse physical function).
Time frame: 12 months
Depression score using Patient reported outcomes measurement information system (PROMIS) measure
Patient reported outcomes measurement information system (PROMIS) measure for depression, numerical value on a scale of 0-100 points, normal average for the general population is 50 with standard deviation of 10 points (higher T scores indicating worse depression).
Time frame: 12 months
Anxiety score using Patient reported outcomes measurement information system (PROMIS) measure
Patient reported outcomes measurement information system (PROMIS) measure for anxiety, numerical value on a scale of 0-100 points, normal average for the general population is 50 with standard deviation of 10 points (higher T scores indicating worse anxiety).
Time frame: 12 months
Peer relationships score using Patient reported outcomes measurement information system (PROMIS) measure
Patient reported outcomes measurement information system (PROMIS) measure for peer relationships, numerical value on a scale of 0-100 points, normal average for the general population is 50 with standard deviation of 10 points (lower T scores indicating worse peer relationships).
Time frame: 12 months
