Blood collection and supply in Tianjin: Statistics and regularity analysis from 2010 to 2019 / 中国输血杂志

ABSTRACT

【Objective】 To analyze and characterize the trend of blood collection and supply in Tianjin from 2010 to 2019, so as to provide references for respective working plans in Tianjin Blood Center. 【Methods】 Through the blood information management system, the issued amount of various blood components from Tianjin Blood Center from 2010 to 2019 was statistically analyzed; the number and respective data of blood donors in Tianjin in recent 10 years were sorted out and analyzed. 【Results】 From 2010 to 2019, the amount of issued blood components in Tianjin Blood Center increased year by year, with an average annual growth rate of 3.22%(×100%). The utilization rate of blood components in clinical increased year by year, reaching 99.99%(642 240.2/642 250.2)by the end of 2019.The consumption of platelets and cryoprecipitated coagulation factor increased rapidly, accounting for 8.89%(57 111.0/642 250.2)and 2.65%(16 989.0/642 250.2), respectively. In recent 10 years, a total of 1 473 172 blood donors have donated blood voluntarily, and the number increased steadily. Among the blood donors, those aged 18-35 took up the largest proportion, reaching 79.13%(116 5548/1 473 172). The ratio of male to female was about 3∶1, with male blood donors accounting for the vast majority.The main blood donors were students, staff and workers. In 2018, the blood donation rate in Tianjin was only 12.2‰, which lagged behind provincial capital cities and economically developed areas in terms of blood collection units per capita and other indicators. 【Conclusion】 Although blood collection and supply in Tianjin is generally developing scientifically and reasonably, the current situation is still very serious.It is necessary to formulate and improve blood donation strategies according to actual situations. The data in this study is helpful inguiding advance planning, overall construction and scientific development of future blood collection and supply in Tianjin.
