摘要
目的通过回顾性对比分析停止互助献血前后机采血小板献血者的献血量、人群结构、献血次数及血液感染性指标阳性等情况,探讨停止互助献血政策对广州采血情况的影响,为调整机采血小板献血者招募方案提供支持。方法2017年4月-2019年3月期间广州地区机采血小板献血者31130名,以2018年3月31日为分界,将2017-04-01至2018-03-31的献血者分为互助组,2018-04-01至2019-03-31为非互助组。对机采血小板献血者的献血量、人群结构、单次献血量、献血次数及血液感染性指标阳性等资料进行分析。结果2018年4月-2019年3月,机采血小板献血量在下降6个月后出现稳定增长;11248名机采血小板献血者中,7015人(62.37%)为初次机采血小板献血者,但69886 U血小板总量中,43137 U(61.72%)来源于非初次机采血小板献血者。与停止互助献血前1年相比,单次献血量2 U献血者占比(75.75%)增加,献4次及以上的机采血小板献血者占比(26.85%)增加,传染病四项筛查及丙氨酸氨基转移酶的阳性率降低,且差异均有统计学意义(P<0.05)。结论停止互助献血后,广州地区血小板供应有所上升,未来应提高初次血小板献血者的人均献血量及转化为重复献血者的比例,促进无偿献血工作可持续发展。
Objective To compare and analyze the blood donation volume,population structure,number of blood donation and positive blood infection index of platelet donors before and after cancellation of mutual blood donation,and explore the effect of cancellation of mutual blood donation policy on blood collection and supply in Guangzhou,and adjust the recruitment program of platelet donors.Methods During the period from April 2017 to March 2019,31130 platelet donors in Guangzhou were divided into mutual aid group(2017-04-01 to 2018-03-31)and non-mutual aid group(2018-04-01 to2019-03-31).The data of blood donation volume,population structure,blood volume per donation,number of blood donation and positive index of blood infection were analyzed.Results From April 2018 to March 2019,the number of apheresis platelet donors increased steadily after six months of decline;among the 11248 apheresis donors,7015(62.37%)were first-time apheresis platelet donors,but of the 69886 U total platelet count,43137 U(61.72%)was from non-first-time apheresis platelet donors.Compared with the year before cancellation of mutual blood donation,the percentage of 2 U blood donors(75.75%)and the percentage of platelet donors(26.85%)who donated 4 times or more increased,the positive rate of four screening tests for infectious diseases and alanine aminotransferase decreased,the differences were all statistically significant(P<0.05).Conclusions After cancellation of mutual blood donation,the platelet supply in Guangzhou went up.In the future,the donation amount per capita of first-time apheresis donors and the proportion of repeat blood donors should be increased so as to keep the sustainable development of blood collection and supply.
