Abstract

We used the Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM) framework to evaluate a Stroke Prevention Team's readiness to prevent strokes in children with sickle cell anemia living in northern Nigeria. The NIH sponsored Stroke Prevention Trial in Nigeria included a goal of a sustainable stroke prevention program. The program's 1-year reach for transcranial Doppler screening was 14.7% (4710/32,000) of which 6.0% (281/4710) had abnormal velocities (≥200 cm/s). All participants with abnormal transcranial Doppler velocities were started on hydroxyurea (effectiveness). The leaders of all 5 hospitals agreed to adopt the program. After 1 year, program-implementation and maintenance rates were 100%, demonstrating the program's feasibility and short-term sustainability.

Flow diagram describing: (1) Program Reach defined as the proportion of children followed in the sickle cell disease clinics at the 5 hospitals receiving transcranial Doppler (TCD) screening as standard care; and (2) Program Effectiveness, defined as the number of children with abnormal TCD velocities at risk for an initial stroke who initiated hydroxyurea treatment as a form of primary stroke prevention, at the 4 hospitals in Kano and 1 hospital in Kaduna, Nigeria. SCA indicates sickle cell anemia.
