Donor blood procurement and the risk of transfusion transmissible viral infections in a tertiary health facility in South-South Nigeria.

BACKGROUND

Blood and blood products are scarce commodities. The demand often outweighs the supply. This study is directed at investigating the blood procurement sources and the risk of viral transfusion transmissible infection.

MATERIALS AND METHODS

The records of the blood transfusion unit of a tertiary health facility in south-south Nigeria were studied. The procurement and screening records from 1 January to 31 December 2009 were analyzed.

RESULTS

7,552 donor records were analyzed, 6,931 were commercial donor and 621 replacement donors. 891 commercial donors were infected, 500 (7.2%) were HIV positive, 323 (4.7%) HBV positive, 42 (0.6%) had HIV and HBV co-infection, while 28 (0.4%) were HCV positive. Twenty-three replacement donors were infected, 16 (2.6%) were HIV positive, 6 (1%) were HBV positive, while 1 (0.2%) were HCV positive. None of the replacement donors had co-infection. The risk of infection was significantly higher with commercial donor procurement (X2=45.07, P<0.001, OD=3.845).

CONCLUSION

Commercial blood donors are still the major source of blood to the hospital and they also have the highest prevalence of transfusion transmissible viral infections in this region thus constitute a major risk transmitting infections to potential recipients.
