Abstract
BACKGROUND: This is the first study on the blood donation trend in Iran at a national level. We report different characteristics of blood donation such as demographic status, donor type, donation trend, and geographical distribution of blood donation in Iran between 2003 and 2017. METHODS: This study used data registered in the donor vigilance part of the Iranian Blood Transfusion Organization. Statistical analysis was conducted using SPSS (SPSS Inc., Chicago, IL, USA) and ArcMap GIS version 10.2 software. A P-value <0.05 was considered statistically significant. RESULTS: Based on the study results, blood donation in Iran reached >2 million units in 2017; moreover, it is predicted that Iran will achieve >29 donations per 1,000 population in 2022. The proportion of regular and repeated donors increased from 77% in 2013 to 87% in 2017. The average blood donation rate in seven provinces was higher than the national average, and the average growth rate of their blood donation per population was positive. CONCLUSION: The results of the current study showed that there is a recent increasing trend toward blood donation in Iran. Furthermore, the largest share of donations is related to regular donors. The increasing proportion of regular and repeated donors has led to the improvement in the quality and consequently health level of donated blood.
