首次及重复献血者血液检测不合格情况的多因素分析

Multivariate analysis of unqualified blood tests in first and repeated blood donors

目的分析初次及重复无偿献血者血液检测情况,通过对不同献血形式,检测项目以及人群分布特征的分析,为制定无偿献血招募,为无偿献血队伍纳入更多健康的血液资源提供参考依据。方法对乌鲁木齐市血液中心2017-2021年无偿献血者样本的检测结果进行分析,分别从检测项目,献血形式以及人群分布特征,比较不同人群初次和重复献血的血液不合格分布情况。结果初次和重复机采血小板献血者各项目血液检验不合格率有统计学意义(P<0.05),初次和重复全血献血者不同年龄不合格率有统计学意义(P<0.001),初次和重复全血献血者和血小板献血者在不同文化程度以及不同职业的不合格率均有统计学意义(P<0.01)。结论2017-2021年乌鲁木齐市无偿献血者中,血液不合格率与献血频次以及人群的年龄,文化程度和职业分布有关。本次研究发现重复献血的高学历的年轻群体不合格率较低。应定期关注感染人群组成变化和人群感染项目流行率变化,对保障血液安全和避免血液资源浪费有重要意义。

Objective To analyze the blood test of primary and repeat unpaid blood donors,and to provide reference for the recruitment of unpaid blood donation and the inclusion of more healthy blood resources in the unpaid blood donation team through the analysis of different blood donation forms,test items and population distribution characteristics.Methods The test results of unpaid blood donors from Urumqi Blood Center from January 2017 to December 2021 were analyzed,and the distribution of unqualified blood in different groups were compared according to the test items,blood donation forms and population distribution characteristics.Results There was statistical significance in the unqualified rate of blood test in different items of platelet donors with different frequency(P<0.05),and the unqualified rate in different ages of whole blood donors with different frequency(P<0.001).The unqualified rates of whole blood donors and platelet donors with different frequency in different education levels and different occupations were statistically significant(P<0.01).Conclusion Among the unpaid blood donors in Urumqi from 2017 to 2021,the blood unqualified rate is related to the frequency of blood donation,age,education level and occupation distribution of the population.The results showed that young people with higher education who donated blood repeatedly had a lower failure rate.Regular attention should be paid to composition changes of the infected population and the prevalence of population infection items,which is of great significance to ensure blood safety and avoid waste of blood resources.
