Background: Transition to adulthood is a vulnerable time for emerging adults (16-25 years of age) with sickle cell disease (SCD), as there is a seven-fold increase in mortality rates during the transition period. Emerging adults with SCD also have the highest rates of hospitalizations, emergency room visits, and hospital readmissions compared to other age groups. Community health worker (CHW) programs have been developed to address outcomes such as patient activation which includes an individual's knowledge, skill, and confidence for managing one's health and healthcare, quality of life, and healthcare utilization for patients with chronic illnesses.

Objective: This paper outlines the design and implementation of iManage SCD, a self-management mobile health application for adolescents and young adults (AYA) with sickle cell disease (SCD) during transition from pediatric to adult health care.

Methods: The Integrate, Design, Assess, Share (IDEAS) framework, emphasizing user insights, iterative design, rigorous assessment, and knowledge sharing, guided the development process. The design team consisted of researchers, psychologists, physicians, social workers, AYA with SCD, and parents of AYA with SCD (n = 16) across three states.

Article Synopsis
  • * A genome-wide association study (GWAS) assessed DNA from 520 SCD patients to find genetic variants related to different SCD features, identifying significant loci tied to hemoglobin levels, acute chest syndrome, and vasoocclusive episodes.
  • * Key findings include established loci near the BCL11A gene and new loci near EMC7 and IDH2, highlighting the importance of genetic factors in how SCD presents in individuals.

Background: Suboptimal medication adherence is common across youth with chronic health conditions and may contribute to health disparities and adverse health outcomes, especially in underserved communities.

Methods: Using pharmacy prescription records and guided by the World Health Organization Multidimensional Adherence Model, we examined patient-, treatment-, and health system-related factors that may affect hydroxyurea adherence in 72 youth with sickle cell disease (SCD), 10-18 years who had participated in the multisite "Hydroxyurea Adherence for Personal Best in SCD" (HABIT) feasibility (6 months) and efficacy (12 months) trials. Pharmacy data were collected from the year prior to study entry through the duration of each trial.

Background: Adolescence and young adulthood are vulnerable developmental periods for individuals with sickle cell disease (SCD), particularly given the impact of social inequities, challenges with transitioning to adult healthcare services, and increased risk for morbidity and mortality. Systems of power, such as institutionalized and interpersonal manifestations of bias, could impact SCD transfer and engagement in adult care through their influence on healthcare transition readiness; yet research in this area is limited.

Objective: To characterize how systems of power impact transition readiness factors described in the Social-ecological Model of AYA Readiness for Transition to Promote Health Equity (SMART-E) framework at the patient, caregiver, and practitioner levels.
