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).

Inclusion Criteria:

- Males or females age 17 years or older

- Have sickle cell disease, defined as those individuals with HbSS, HbSC, HbSβ0Thal,
HbSβ+Thal genotypes

- Receive care at a participating pediatric sickle cell disease center.

- Appropriate for transfer to an adult hematologist within 12 months

Exclusion Criteria:

- 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).
