Journal Title: Chinese Journal of Blood Transfusion - Year 2022, Vol 35, Issue 11
Abstract
Objective To study the characteristics of voluntary apheresis platelet donors in Zhoushan Islands and its influence on the collection and supply of apheresis platelets. Methods From January 1, 2017 to December 31, 2021, 1038 eligible donors were selected out of 1151 apheresis candidates for demographic analysis, donation time analysis, blood routine test. We also investigated whether the current supply of apheresis platelet met the needs of clinical. The lapsed donors(with only one donation) were telephone interviewed to investigate the lapsing reasons. Results From 2017 to 2021, the median (M) ratio of platelet donors to the population in Zhoushan City was 0.454 ‰. And 90.18% (1038/1151) of the candidates completed donation, involving 2659 donations and 3205 U products. The per capita donation amount was (1.29±0.77) U per person, which basically met the blood demand in clinical of Zhoushan Islands. The 1038 platelet donors were 18 to 59 yeas old[M(QR) 34(16)], and 47.50% (493/1038) of them aged 31 to 45; the ratio of male to female blood donors was 2.0∶1; 70.61% (733/1038) had college education or above; ABO blood group profile was A>O>B>AB. There were several peak periods of donation during 2017~2021: the second and third quarters of 2017~2019 and the third quarter of 2020; none in 2021, as yeae 2021 was volatile. The donation proportion of the first quarter was the lowest throughout 2017~2021. In 2017 and 2018, the proportion of donors with one donation accounted for 79.79% (75/94) and 51.63% (95/184), respectively. From 2019 to 2021, the proportion of donors with twice or more donation accounted for 60.35% (137/227), 57.36% (187/326) and 53.13% (170/320) , respectively. During 5 years, 10.88% (113/1051) of the candidates failed to donate platelets, of whom 72.57% (82/113) were due to unqualified pre-donation testing. Conclusion The donation behaviors in Zhoushan have been affected by each above-mentioned demographic factors. The awareness of donation and donation services in Zhoushan have been improved as combing the special geographic condition and demographic characteristics together, and the donation units is elevating yearly which has met the clinical needs of the whole island.
