Influencing factors and preventive measures of adverse reactions to blood donation in Beijing from 2017 to 2020

Abstract

Objective To investigate the high-risk groups and scenarios of adverse reactions to blood donation(ARBD) through statistical analysis of the incidence and distribution of ARBD in Beijing from 2017 to 2020, and discuss the preventive measures, so as to retain more regular blood donors with better service and blood donation experience. Methods The data of 1 047 036 voluntary blood donors during 2017 to 2020 were reviewed. The incidence of blood donation reactions was counted, and factors as gender, blood collection sites, blood group and number of blood donations were collected, the influencing factors of ARBD were analyzed to put forward targeted solutions. Results Among 1 047 036 blood donations in Beijing from 2017 to 2020, 2 163 (0.21%) developed ARBD. The incidence of ARBD in women was twice that in men, and was highest in age group 18 to 25 years old (47.8%, 1 034/2 163). In terms of blood donation sites, the incidence of ARBD was close under different blood donation environments, but ARBD occurred in mobile donation sites accounted for 65.51% (1 417/2 163). The incidence of ARBD in different blood types was basically the same, that of repeated blood donors was the lowest, and that of first-time blood donors accounted for 66.07% (1 429/2 163). The incidence of ARBD occurred within 30 minutes after blood donation was 43.64% (944/2 163), and it was dominated by systemic manifestations (Class B) (73.05%, 1 580 / 2 163). Conclusion Gender, age, blood donation sites, number of blood donations, occurrence time and ARBD categories were the influencing factors of ARBD. It is suggested to pay more attention to women, young and first-time blood donors, improve blood donation environment, and stay for 30 minutes after blood donation.
