Influences of seasonal recruitment mode of voluntary blood donors on blood collection and supply of whole blood and erythrocyte components

Abstract

Objective To explore the influences of seasonal recruitment mode of voluntary blood donation on blood collection and supply of whole blood and erythrocyte components. Methods A total of 239 949 voluntary blood donors who participated in whole blood and erythrocyte components donation during January 2013 to December 2018 in Binzhou Blood Center were chosen as subjects. There were 165 564 male donors and 74 385 female donors in the subjects, whose age ranged from 18 to 55 years. The Qiao Information Management System v9.0 (Tangshan Qiao Technology Co., Ltd.) was used to collect all the blood donation data of 239 949 blood donors in this study, such as the time of participating in blood donation, the mode of blood donation, the amount of blood collection and supply of whole blood and erythrocyte components. The blood collection amount of whole blood and erythrocyte components, the seasonal ratio of blood collection, the blood supply amount of whole blood and erythrocyte components, the seasonal ratio of blood supply, as well as the difference between seasonal ratios of blood collection and blood supply in Binzhou Blood Center in each season from 2013 to 2018 , were calculated respectively. The total blood collection and supply amount of whole blood and erythrocyte components in Binzhou Blood Center in four seasons from 2013 to 2018 were compared by variance analysis, and the least significant difference (LSD) method was used for comparison between two seasons. The procedures followed in this study were in line with the requirements of the revised Helsinki Declaration of the World Medical Association in 2013. Before blood donation, all the blood donors signed the Informed Consent of Blood Donors. Results ① In this study, the seasonal ratios of blood collection of whole blood and erythrocyte components of Binzhou Blood Center in the spring, summer, autumn and winter from 2013 to 2018 were 95.8%, 93.8%, 113.4% and 97.0%, respectively. Among them, the seasonal ratios of group blood collection were 39.9%, 56.7%, 190.3% and 113.2%, respectively; the seasonal ratios of street blood collection was 117.9%, 108.5%, 83.1% and 90.6%, respectively. In spring, summer, autumn and winter form 2013 to 2018, the blood collection amount of whole blood and erythrocyte components of Binzhou Blood Center were (15 877.0±924.3) U, (15 548.2±1 105.3) U, (18 790.8±1 057.7) U and (16 065.7±1 062.3) U, respectively. There was a statistically significant difference in blood collection amount among four seasons (F=12.418, P 0.05). ③ The difference of seasonal ratios between the total blood collection and supply of whole blood and erythrocyte components of Binzhou Blood Center in spring, summer, autumn and winter from 2013 to 2018 were -5.9%, -3.0%, 13.8% and -4.9%, respectively. Only the blood collection in autumn could meet the supply requirements, and there were shortages in other three seasons. Conclusions In recent years, there are seasonal insufficiency of blood collection and supply in Binzhou. Recruitment methods of voluntary blood donation should be coordinated and complemented by group blood collection and street blood collection according to the characteristics of local seasonal climate change, so as to ensure the balance of blood collection and supply to meet the clinical needs.
