| Abstract
Background and Objectives
The use of blood and blood products is one of the necessities of clinics. Blood donation should comply with international criteria because of the probability of transmission of infections following blood transfusion. One of the priorities in reliable blood transfusion centers in the world and in our country will be the improvement of the donor recruitment methods. It seems that recent methods are useful in non-emergencies. The use of such methods in emergency cases like what happened in Bam earthquake is practically impossible. This study aims to see if this would endanger blood safety.
Materials and Methods
In this cross-sectional study, 4188 blood units including 2094 blood units collected (as case group) immediately after Bam earthquake and 2094 units collected (as control group) before Bam earthquake were studied. In this process all blood units in the case and control groups were tested for HBV, HCV and HIV by Elisa method. We repeated positive results by Elisa. If test results were positive again, we would use confirmation tests (western blot and RIBA).
Results
The results show that there is a significant difference in Binomial test between control and case group (PV<0.001) for HBV and HCV before and after Bam earthquake however, no difference was observed for HIV between two groups.
Conclusions
Higher rate of serologically positive results in case group shows that there is a higher risk in emergencies for transmission of viral infections. To decrease this risk, it is proposed that blood donation is managed by implementing control mechanisms in emergency conditions. |
