Intentional and unintentional nonadherence to hydroxyurea among people with sickle cell disease: a qualitative study.
The objective of this study was to examine barriers to patients' adherence to hydroxyurea-use regimens by using the intentional and unintentional medication nonadherence framework. Individuals with sickle cell disease (SCD) aged 15 to 49.9 years who were participants in the Sickle Cell Disease Implementation Consortium (SCDIC) Needs Assessment were interviewed. Findings showed that participants with SCD more frequently endorsed adherence barriers that fell into the unintentional nonadherence type vs intentional nonadherence type. Results from this study will help SCD health care providers to understand patient choices and decisions as being either unintentional or intentional, to guide tailored clinical discussions regarding hydroxyurea therapy, and to develop specific, more nuanced interventions to address nonadherence factors.

Development of the incharge health mobile app to improve adherence to hydroxyurea in patients with sickle cell disease: user-centered design approach.
This study looked at how use of a newly developed mobile app called InCharge Health can help sickle cell disease (SCD) patients adhere to their prescribed medication use of hydroxyurea. Four phases were used to develop the mobile app with substantial input from users and by mapping the Health Belief Model (HBM) as the framework that guided the choice for its components. More than half of the patients reported potentially low health literacy. Preferred patient app features included 7 key components: medication reminders and tracker, disease education, communication, personalization, motivation, support during pain episodes, and social support. This information was translated into features within the app.

Sickle-cell disease co-management, health care utilization, and hydroxyurea use.
Sickle-cell disease (SCD) causes significant morbidity, premature mortality, and high disease burden, resulting in frequent health care use. Comanagement may improve utilization and patient adherence with treatments such as Hydroxyurea. The purpose of this study was to describe acute-care utilization in Medicaid-enrolled patients with SCD, patient factors associated with comanagement, and adherence to Hydroxyurea. The investigators concluded that comanagement was a factor in predicting HUadherence, but further studies are needed to identify the frequency and components of comanagement needed to increase adherence and reduce acute care utilization.

Beliefs about hydroxyurea in youth with sickle cell disease.
The objectives of this study were to assess beliefs about hydroxyurea using the Beliefs about Medicines Questionnaire (BMQ), and to examine the relationship of patients' beliefs to their hydroxyurea adherence and health-related quality of life (HRQOL). The investigators found that beliefs about hydroxyurea correlated with HRQOL scores and adherence levels. The authors suggest that addressing patients' concerns about hydroxyurea and medications overall as well as routine assessment of adherence and beliefs could help to overcome adherence barriers.

Utilizing a novel mobile health "selfie" application to improve compliance to iron chelation in pediatric patients receiving chronic transfusions.
Iron chelation therapy can prevent iron overload for pediatric patients with sickle cell disease and beta-thalassemia major; however, adherence is suboptimal. Therefore, the researchers developed an intensive training program (ITP), to improve medication management and disease knowledge. The objectives were to determine feasibility of the ITP and its preliminary impact on adherence, disease knowledge, and health outcomes. The mobile ITP was feasibly implemented in a clinical setting.
