Abstract:
【Objective】 To investigate the impact of ceasing mutual blood donation on voluntary blood donation in Guangzhou. 【Methods】 The data of blood donation from July 2016 to December 2019 (42-month before and after the official cease of mutual blood donation) in the Blood Collection and Supply System of Guangzhou Blood Center, including whole blood donations and apheresis platelets donations, were collected for interrupted time series analysis by month. Blood donors who donated (either whole blood or platelets) during 2016 were followed up until December 31, 2019, and the re-donation rate was analyzed by Chi-square test, t test and logistic regression analysis. 【Results】 The results showed that ceasing mutual blood donation had a significantly positive effect on the increase of platelet donations, but had no significant effect on whole blood donation. In 2016, whole blood donations and platelet donations were mainly voluntary (86.4% and 60.8%, respectively). In comparison of voluntary blood donation, the overall blood deferral rate(by dual assays) of mutual blood donation was higher (P<0.01), but the difference diminished as they donated twice or more. The re-donation rate of blood donors (mutual non-remunerated, voluntary, or both) all increased after the ceasing of mutual blood donation (mutual non-remunerated, : 4.7% vs 4.0%, χ2=29.8, P<0.01; voluntary: 24.8% vs 9.9%, χ2=17295.3, P<0.01; both: 36.3% vs 28.1%, χ2=29.3, P<0.01). The re-donation rate of mutual platelet donors decreased after the ceasing of mutual blood donation, but the number of voluntary platelet donors increased. 【Conclusion】 The ceasing of mutual blood donation was in favour of voluntary blood donation in Guangzhou since various means had been previously adopted by Guangzhou Blood Center to create a long-term mechanism of voluntary blood donation. The number of voluntary blood donors has increased, and the clinical use of blood has been further guaranteed.
