TABLE 16Health states included in the model

Health stateDescription
No transfusion, TCD scan < 200 cm/secondThe population in this state has normal blood velocity and therefore does not require blood transfusions
No transfusion, TCD scan > 200 cm/secondThe population in this state has a high blood velocity but is not receiving blood transfusions. This reflects the small proportion of children in clinical practice who require a confirmatory scan before commencing blood transfusion
Transfusion, TCD scan > 200 cm/secondThe population in this state has a high blood velocity, and is receiving blood transfusions. In this state the patient will also receive treatment for blood transfusion-related health outcomes, such as chelation therapy for iron overload
DeathThe population in this state has died
