|Blood Transfusion Services Impact Model and Manual (UNAIDS, 1999, 29 p.)|
|1. Introduction to Blood 3.0 and project|
The initial structure of the model developed is the result of a series of consultations with staff at UNAIDS, and following a review of the literature on HIV and blood transfusion services. Simple flow charts were used to describe the initial model structure and underlying assumptions. These were used to enable a range of groups to guide the structure of the model developed.
The model and its underlying assumptions were field tested in Zambia in 1995, in collaboration with the Zambia National Blood Transfusion Services and the Zambia National AIDS Control Programme. Further field-testing will be required to assess the more general applicability of the model, and to refine its format to the needs of specific users.
Version 3.0 was finalised in February 2000, and can be obtained free of charge from UNAIDS. It is likely that further revisions to the model will be made once further feedback on its use has been obtained. Anyone who would like to receive up-dated copies of the model should write to London School of Hygiene and Tropical Medicine giving their contact details, and describing how they plan to use the model. They will then be sent the latest version of the model and an accompanying manual. Copies of any reports or publications arising from use of the model should be sent to UNAIDS, and to Dr. C. Watts at the London School of Hygiene and Tropical medicine. Feedback on the model would also be greatly appreciated, and will be used to guide the future development of the package.
