ABSTRACT

【Objective】 To conduct a retrospective statistical analysis of the blood discarding situation in Xuzhou Central Blood Station in the past 5 years, so as to explore relevant measures and strategies to reduce blood discarding and save blood resources. 【Methods】 The discarding situation of our station from 2018 to 2022 was systematically sorted out, and Big data analysis base on the two causes, which was unqualified testing and non unqualified testing, was conducted. 【Results】 The total blood discarding rate of our station from 2018 to 2022 was 9.57% (94 273/985 178), and there was a difference in the total discarding rate between different years (Panti-TP(0.23%, 2 263/985 178)>anti-HCV(0.14%, 1 354/985 178)> HBsAg(0.13%, 1 285/985 178)>anti-HIV (0.12%, 1 140/985 178). The unqualified rate of ALT in males (0.63%, 1 993/317 437) was significantly higher than that in females (0.19%, 388/209 601) (P<0.05). The unqualified rate of ALT at the age of 18-25 accounted for 55% (0.49/0.89) of the total unqualified rate of ALT, and was significantly higher than other age groups (P <0.05). 【Conclusion】 It is suggested to improve the public awareness of voluntary blood donation, strengthen health consultation before blood donation, promote staff training so as to reduce blood discarding rate, as well as ensure sufficient, safe and effective clinical blood use.
