Abstract

Aims: Despite policies advocating centralised transfusion services based on voluntary donors, the hospital-based replacement donor system is widespread in sub-Saharan Africa. The aim of this study was to evaluate the cost of all laboratory resources needed to provide a unit of safe blood in rural Malawi using the family replacement donor system

Methods: Full economic costs of all laboratory tests used to screen potential donors and to perform cross-matching were documented in a prospective, observational study in Ntcheu district hospital laboratory.

Results: 1729 potential donors were screened and 11,008 tests were performed to ensure that 1104 units of safe blood were available for transfusion. The annual cost of all transfusion-related tests (in 2005 US$) was $17,976, equivalent to $16.28 per unit of transfusion-ready blood. Transfusion-related tests used 53% of the laboratory’s total annual expenditure of $33,608.

Conclusions: This is the first study to provide prospective economic costs of all laboratory tests associated with the family replacement donor system in a district hospital in Africa. Our results show that despite potential economies of scale, a unit of blood from the centralised system costs about three times as much as one from the hospital-based ‘replacement’ system. Factors affecting these relative costs are complex but are in part due to the cost of donor recruitment in centralised systems. In the replacement system the cost of donor recruitment is entirely borne by families of patients needing a blood transfusion.
