我国地市级血站新冠疫情期间红细胞成分血库存情况的回顾性分析

Impact of COVID-19 epidemic on inventory of red blood cells in local and municipal blood stations in China

目的评估分析新冠疫情对我国地市级血站红细胞成分血库存情况的影响,为突发公共卫生事件管理提供参考经验。方法收集2018—2021年相关数据,回顾性分析我国24家地市级血站新冠疫情期间和非疫情期间合格入库红细胞成分血数量、红细胞成分血库存使用效率、红细胞成分血日均发放量、400 mL全血制备的红细胞成分血发放率、红细胞成分血发放时的平均保存天数、红细胞成分血平均每日库存数量和红细胞成分血平均每日库存数量维持发放时间的差异。结果疫情期间较非疫情期间合格入库红细胞成分血数量(117525.979±52203.175)U和红细胞成分血日均发放数量(156.468±70.186)U增长,但红细胞成分血库存使用效率降低(97.24%±0.51%),均差异显著(P<0.05);400 mL全血制备的红细胞成分血发放率(73.88±20.30)%、红细胞成分血发放时的平均保存天数(13.040±3.486)d、红细胞成分血平均每日库存数量(2280.542±1446.538)U、红细胞成分血平均每日库存数量维持发放时间(15.062±7.453)d无明显差异(P>0.5)。结论新冠疫情期间,红细胞成分血库存运行良好,总体库存量维持相对稳定,库存构成和库存期无明显变化。

Objective To evaluate and analyze the impact of COVID-19 epidemic on inventory of red blood cells(RBCs)in local and municipal blood stations in China,and to provide reference for the management of public health emergencies.Methods Relevant data from 2018 to 2021 were collected,and the differences in the volume of qualified RBCs,the usage efficiency of inventory RBCs,the average daily distribution of RBCs,the blood distribution rate of RBCs prepared by 400 mL whole blood,the difference in the average storage days of RBCs at the time of distribution,the average daily inventory of RBCs and the time of the average daily inventory of RBCs to maintain the distribution in 24 local and municipal blood stations in China during the COVID-19 epidemic and non-epidemic periods were retrospectively analyzed.Results Compared with non-epidemic periods,the volume of qualified RBCs[(117525.979±52203.175)U]and the average daily distribution of RBCs[(156.468±70.186)U]increased significantly,but the usage efficiency of inventory RBCs decreased(97.24%±0.51%)significantly(P<0.05).There was no significant difference in the blood distribution rate of RBCs prepared by 400 mL whole blood(73.88%±20.30%),the average storage days of RBCs distribution(13.040±3.486),the average daily stock quantity of RBCs[(2280.542±1446.538)U]and the time of the average daily inventory of RBCs to maintain the distribution[(15.062±7.453)d](P>0.5).Conclusion During the COVID-19 epidemic,the inventory management of RBCs operated well,the overall inventory remained relatively stable,the stock composition and storage period showed no significant change.
