新型冠状病毒感染发生前后26家采供血机构全血献血人群基本特征的对比研究

Characteristics of whole blood donors from 26 blood stations before and after the outbreak of COVID-19:a multicenter study

目的 分析比较新型冠状病毒感染发生前后全血献血人群的基本特征。方法 收集2018—2021年我国26家采供血机构全血献血人群基本特征相关数据,剔除无效数据后,对全血献血者基数变化趋势、活跃献血者(重复献血者)人数、献血频率、献血者平均年龄、初次献血者招募等数据进行统计分析,并对相关指标进行分析,比较新型冠状病毒感染发生前后的变化。结果 14个指标中受疫情影响差异较大的有8个(占比57%)。其中,全血献血者基数变化趋势受疫情影响变化较大,疫情期间整体增长率高于疫情前(P<0.05);活跃献血者人数均为增长趋势,疫情期间高于疫情前(P<0.05);献血频率疫情期间低于疫情前(P<0.05);献血者平均年龄、女性献血者平均年龄受疫情影响波动范围较大,两者较疫情前偏高(均P<0.05);初次献血者招募<25岁组和≥25岁组参加率受疫情影响差别较大,呈不规则波动且波动幅度范围较大(均P<0.05);初次献血者占全部献血者的比例受疫情影响呈不规则波动,整体占比低于疫情前(P<0.05)。结论 26家采供血机构全血献血人群新型冠状病毒感染发生后较发生前呈增长趋势,受疫情影响部分地区部分指标有明显波动。

Objective To analyze the basic characteristics of whole blood donors from blood stations before and after the outbreak of COVID-19.Methods After excluding invalid data,data related to the basic characteristics of whole blood donors collected from 26 blood stations in China during 2018 to 2021 were statistically analyzed,including the trend of total whole blood donors,the number of repeated blood donors,the frequency of blood donation,the average age of donors and the recruitment of first-time blood donors.Results Affected by the epidemic,8 out of 14 indicators were with large variations,accounting for 57%.The overall growth rate of total whole blood donors during the epidemic was higher than before the epidemic(P<0.05).The number of repeated blood donors has shown an increased trend,with a higher number during the epidemic than before(P<0.05).The frequency of blood donation was lower during the epidemic than before(P<0.05).Average ages of blood donors and female blood donors fluctuated widely during the epidemic,both higher than those before the epidemic(P<0.05).The donation rate of first-time blood donors<25 years old and≥25 years old varied widely and irregularly during the epidemic(both P<0.05).The percentage of first-time blood donors fluctuated irregularly during the epidemic,with overall percentage lower than that before the epidemic(P<0.05).Conclusion Whole blood donors from 26 blood stations increased after the outbreak of COVID-19,and some indicators in certain areas showed significant fluctuations during the epidemic.
