4.6 Transfusion recipients

Inputs describing estimates of HIV prevalence among transfusion recipients among the main wards receiving blood products and the percentage of transmission recipients not surviving to discharge. This input is used to estimate the numbers receiving blood products that are already HIV infected. Clearly, such people cannot be infected by infected blood products. As there is likely to be a degree of uncertainty associated with the HIV prevalence estimates, the model requires low, medium high estimates for each ward. These ranges are then used to obtain low, medium and high estimates of the numbers of HIV infections averted and surviving to discharge as a result of the provision of safe blood products.
