Community Health Workers and mHealth for Sickle Cell Disease Care

Emerging adults with sickle cell disease (SCD) experience a seven-fold increase in mortality rates during the transition period (16-25 years of age). This staggering increase in mortality and acute care utilization during this vulnerable period is partly due to difficulty coordinating care during the transition to adult care. Critical psychosocial issues further compound the vulnerability of emerging adults with SCD during the transition from pediatric to adult care9. Unfortunately, none of these transition intervention studies included adolescents or young adults with SCD. Patients, parents, and providers of those with SCD agree that the ability to independently perform chronic disease self-management is critical to staying healthy during this turbulent transition period.

Self-management support is a key component of the Chronic Care Model. Community health worker (CHW) programs are increasingly popular and have efficacy on chronic disease self-management and system navigation. Mobile health platforms are equally popular, and have efficacy on self-management and adherence. Unfortunately, the effectiveness of mHealth and tailored texting among emerging adults with SCD is still unknown. Furthermore, also unknown is the comparative effectiveness of CHW programs and mHealth.

The purpose of the study is to determine the comparative effectiveness of CHW programs and mHealth among emerging adults with SCD during transition versus enhanced usual care to improve health-related quality of life and acute care use for transitioning youth with SCD.

The primary objective of this study is to compare the effectiveness of two self-management support interventions (community health workers and mobile health) versus enhanced usual care to improve health-related quality of life and acute care use for transitioning youth with SCD. The secondary objectives are to:

* Identify and quantify whether patient activation, self-management behaviors, biologic markers, and transfer to adult care are mediators of intervention treatment effects.
* Identify individual and family factors that moderate intervention treatment effects

The exploratory aim is to:

•Explore the association of enhancements to usual care on pediatric and adult acute utilization

The study population will consist of all patients with SCD who are 17 or older and are appropriate for transfer to an adult hematologist within 12 months. Excluded are individuals with an intellectual disability that is severe enough that the individual would not have the capacity to interact with a mobile or web-based program even with assistance or have a conversation with a community health worker (i.e. non-verbal).
