ABSTRACT

【Objective】 To study and analyze the basic characteristics of blood donors under the COVID-19 epidemic in Tianjin area, so as to provide data support for improving the blood collection for emergency incidents. 【Methods】 The blood collection data of Tianjin Blood Center under the COVID-19 epidemic in 2020 were collected in terms of the number of blood donations, changes in blood donation units over time, group blood donation, donations given by regular blood donors and donations inside fixed blood donation sites, registered residence, gender, age, education, occupation, individual donation, group donation, and the annual daily blood collection and delivery data in Tianjin. 【Results】 The number of blood donations and donation units in Feb 2020 decreased by 56.96%(3 226/7 496-1)and 62.40%(5 382/14 314.5-1)compared with the same period in 2019, and decreased by 56.87%(3 226/7 480-1)and 60.70%(5 382/13 695.7-1)compared with the average value in the previous five years. The number of blood donations, donation units and rate of 400 mL donation in 2020 decreased by 13.25%(119 107/137 293-1), 17.7%(205 196.5/249 405-1)and 12.83%(66.0/75.8-1)respectively. Meanwhile the units of group donation increased by 22.59%(44 118.5/35 989.0-1)as compared with those in 2019. The proportion of regular blood donors raised up to 17.31%(20 623/119 107, which was the highest in recent 6 years. During the epidemic period, the number of blood donations of local registered residence, women, over 36 years old, with bachelor and above degree increased by varied extent compared with previous years. Workers, staff members and others were the main groups of voluntary blood donation, and civil servant, medical workers, farmers and teachers also played a certain role during the epidemic. 【Conclusion】 The clinical blood use in Tianjin was basically guaranteed during the COVID-19 epidemic. It is suggested to further optimize the structure of voluntary blood donors, establish a diversified and multi-level group blood donation team, and increase the number of regular blood donors.
