Abstract

BACKGROUND: Blood component donations by apheresis has become more common in modern blood transfusion practices. However, apheresis donation still remains less common in China. This study describes the demographic profile and transfusion-transmissible infection (TTI) prevalence among donors making apheresis platelet (AP) donations compared to those making whole blood (WB) donations and the differences among five geographically diverse blood centers in China. STUDY DESIGN AND METHODS: This is a descriptive study using data from all successful donations at the five blood centers in 2008 and 2009. Donor demographic and TTI screening reactive rates were collected for WB and AP donations and blood centers. Logistic regression was used to identify independent factors associated with AP donations. RESULTS: From January 1, 2008, to December 31, 2009, there were 512,594 WB and 26,199 AP donations at five blood centers. AP donations accounted for 4.9% of all donations. AP donations have lower reactive rate than WB donations for hepatitis B virus surface antigen, hepatitis C virus antibodies, human immunodeficiency virus antibodies, and syphilis screening testing. Males, donors older than 25 years old, non-Han donors, and donors with below high school educational level were more likely to make AP donations. The characteristics of AP donations differed among the five Chinese blood centers. CONCLUSION: Our analysis suggests that the characteristics of AP donations in China are different from WB donations and differ among the five Chinese blood centers. Some of the differences are likely due to different recruitment policies. Further studies should be conducted to understand what motivates Chinese blood donors to participate as AP donors.
