Characteristics of elderly apheresis platelet donors and analysis of pre-donation testing results
Journal Title: Chinese Journal of Blood Transfusion - Year 2022, Vol 35, Issue 7
Abstract
Objective To study and analyze the characteristics of 56-60 years old apheresis platelet donors and the results of pre-donation blood testing in Tianjin, so as to provide reference for the management of blood stations and the maintenance and retention of blood donors. Methods The information of platelet donors were collected by Tianjin Blood Center from July 1, 2012 to June 30, 2021.The donors aged 56-60(the observation group) were compared with donors aged 18-55(the control). The number of blood donations, male to female ratio, donation frequency, proportion of two-therapeutic-amount donation, rate of deferred donation, incidence of adverse reactions to blood donation, etc of the two groups were studied. The pre-donation test results of the two groups were also compared through the analysis of the unqualified factors of blood routine. Results From 2012 to 2021, there were 2 837 platelet donors aged 56-60 in Tianjin, and the donation frequency and proportion of two-therapeutic-amount donation were significantly higher than those in the control. The blood routine indexes were significantly different between two groups, but all fluctuated within the normal range(P<0.05). More donors in the observation group than the control were deferred due to unqualified blood routine indexes, mainly caused by Hb deferral. Conclusion In the past 9 years, the number of apheresis platelet donors aged 56-60 in Tianjin has been stablely increasing. Elderly donors always meet the health requirements of donations according to the results of blood tests. Close monitor of the blood routine indexes, however, should be paid to such population to ensure the elderly donor health and donation safety.
