2014-2018年广州市无偿献血者采血不足量直接报废情况分析

Analysis insufficient blood collection events among voluntary blood donors lead to direct abandon in Guangzhou from 2014 to 2018

目的分析广州市无偿献全血者采血不足量导致直接报废的情况。方法根据2014-2018年间广州市无偿献血者的数据,分析采血不足量导致直接报废的原因,了解献血者不同性别、年龄、献血次数和献血量等因素与采血不足量之间的关系,分析5年间发生采血不足量事件的原因与变化趋势。结果 2014-2018年共发生955例(0.07%)献全血者采血不足量直接报废事件。2018年由于献血不良反应导致采血不足量事件的比例比2014年有所下降(x2=3.87,P=0.04);选择献血400 mL的献血者发生采血不足量事件的比例最高,且呈现逐年下降趋势;2014年发生采血不足量事件与女性献血者和献血反应成正比,与献血次数成反比,选择献血300 mL与400 mL均比选择200 mL更容易发生采血不足量。而2018年与2014年对比,区别在于发生采血不足量不再与性别和选择献血400 mL有关。结论献血不良反应所导致的采血不足量事件有所下降,性别和选择献血400 mL不再与发生采血不足量有关。

Objective To analyze the situation of direct abandon caused by insufficient blood collection of voluntary blood donors in Guangzhou.Methods Based on the data of voluntary blood donors in Guangzhou from 2014 to 2018,the reasons for direct abandon due to insufficient collection during blood donation were analyzed.The relationships between the gender,age,number of donations,quantity of donation and other factors and insufficient blood collection were analyzed.The causes and trends of insufficient blood collection during blood donation in 5 years were analyzed.Results From 2014 to 2018,a total of 955 events(0.07%) of blood samples abandoned due to insufficient blood collection.In 2018,the proportion of insufficient blood collection events due to adverse reactions decreased compared with 2014(χ~2=3.87,P=0.04).The proportion of insufficient blood collection events was the highest among donors who chose to donate 400 mL blood,and showed a decreasing trend year by year.In 2014,the occurrence of insufficient blood collection was positively associated with female and adverse reaction,but negatively associated with blood donation frequency.Donors who chose to donate 300 mL and 400 mL blood were more prone to insufficient blood collection than those chose 200 mL.However,the difference between2018 and 2014 was that insufficient blood collection event was no longer related to gender and the selection of donating 400 mL blood.Conclusion The proportion of insufficient blood collection events due to adverse reactions decreased;gender and choosing 400 mL blood donation were no longer associated with the occurrence of insufficient blood collection.
