NCT03621826

Brief Summary

DISPLACE is a three part, multi-center U.S. based study to evaluate the barriers to stroke screening and prevention in children with sickle cell anemia (SCA). In the United States, TCD (Transcranial Doppler ultrasound) is a proven method of screening children with SCA for stroke. However, many children are not getting the screening they need. This study will examine the issues that hinder and help children get the screening at 28 different hospitals and sickle cell centers to improve care for all children with sickle cell anemia. The investigators will then plan a study (part 3) aimed to improve stroke screening and prevention in sickle cell anemia.

Outcome Measures

Primary Outcomes (3)

  • Annual TCD screening rates (retrospective data assessment)

    Current rate of TCD screening over the last 5 years

    2 years

  • Identify the barriers and enablers to TCD screening

    This study will assess two different implementation strategies to improve TCD screening. To determine which strategy is more effective, a difference in TCD screening rates of at least 17% between intervention arms is necessary. If there is not at least a 17% difference in annual TCD screening rates, it will be impossible to determine the optimal implementation procedures

    2 years

  • Retrospective assessment of initiation of chronic transfusion therapy in patients over the last 5 years in those children at risk of stroke

    Patients with abnormal TCD should be started on chronic transfusion therapy. The goal of the intervention is to increase institutional initiation of CRCT in at least 95% of patients noted to have abnormal TCD

    2 years

Secondary Outcomes (1)

  • Evaluate patient and stakeholder reported barriers to CRCT

    2 years

Study Arms (1)

Children with Sickle Cell Anemia

Data from patients with sickle cell anemia will be entered into a retrospective database for evaluation of implementation rates of TCD (stroke) screening). A small number of these children/parents/stakeholders will be selected by convenience sampling to participate in a survey and/or interview to assess barriers and enablers to stroke prevention therapy.

Other: Questionnaire/Interview

Interventions

A convenience sample of patients/parents and stakeholders will be asked to participate in a survey and/or interview to evaluate barriers to care in sickle cell.
