Blood safety & prevalence of transfussion transmissible viral infections among donors at the Red Cross Blood Bank in Gondar University Hospital.
BACKGROUND
Although millions of lives are saved by blood transfusion, unsafe transfusion is also putting millions of people at risk of Transfusion Transmissible Infections (TTI). In Ethiopia the safety and magnitude of blood transfusion and TTIs is not well investigated


OBJECTIVE
to investigate the magnitude of TTIs and assess TTI related risk factors among blood donors.


METHODS
Cross-sectional study among blood donors at the Red Cross Society Blood Bank in Gondar University Hospital, North West Ethiopia.


RESULTS
The study was conducted among 600 adult blood donors between April and July 2004. Their mean age was 28 +/- 10.4 years (range: 16-64) and 66% of them were urban dwellers. The donors included farmers (30.7%), daily laborers (22.7%) and students (20%). All the donors were first time donors and 75% of the donations were replacement donations by remunerated donors or family members. The prevalence of HIV, Hepatitis B surface antigen (HBSAg) and Hepatitis C virus (HCV) infections were 4.5% (95%CI: 3.0-6.6), 8.2% (95%CI: 6.2-10.7) and 5.8% (95%CI: 4.2-8.1), respectively. The overall discard rate of donated blood because of these viral markers was 16.3%. In univariate analysis, HCV infection was significantly associated with presence of HIV (OR: 5.36, 95%CI: 2-14.3). Experiences of traditional surgical incisions or phlebotomy were present in 93.8% of donors. While 6.5% of donors admitted a history of multiple sexual partners, none of them admitted a history of any sexually transmitted infections (STI).


CONCLUSIONS
The prevalence of TTIs among blood donors is very high. The majorities of blood donors are replacement or paid donors with one or more of the risk factors for TTIs implying that blood transfusion is unsafe. These findings call for the urgent implementation of the national strategy for safe blood transfusion in Ethiopia. As the utilization of advanced technology and skilled-personnel-based screening of blood are not in the immediate horizon, establishing stringent selection criteria of donors and setting clinical indications for transfusion would be indispensable and cost-effective interventions to minimize the risk of TTIs to blood recipients in Ethiopia.
