ABSTRACT
【Objective】 To study the current situation of apheresis platelets collection in various regions of Gansu province by comparing and analyzing relevant data from blood stations in 14 prefecture-level cities of Gansu province. 【Methods】 The units of collected platelets and rate of double-dose collection in 13 regional blood stations and 1 provincial blood center from 2016 to 2020, as well as the clinical supply and demand was statistically analyzed. 【Results】 From 2016 to 2020, the total units of platelets collected by 13 blood stations and 1 blood center in Gansu increased from 11 255 U to 15 270 U, with the increase rate at 35.7% in 5 years, and mainly were collected by the provincial blood center (74.57%, 50 253/ 67 392). Although the rate of double-dose collection in the province showed a steady upward trend, only 3 blood stations realized annual double-dose collection more than 20%. There was still a gap of about 10% between supply and clinical needs. 【Conclusion】 Although the number of platelet collections and units in each blood station in Gansu is on the rise in general, the units collected varies in each blood station. Therefore, further measures need to be taken from the aspects of publicity, recruitment, optimizing the collection process, improving the rate of double-dose collection, retention of regular blood donors and regional coordination to increase the collection units, narrow down the regional gap and ensure the balance between supply and demand.
ABSTRACT
【Objective】 To analyze the comprehensive factors causing adverse reactions to apheresis platelet donation(ARAPD), so as to provide references for effective prevention of ARAPD. 【Methods】 The 272 cases of ARAPD from 2012 to 2019 in Lanzhou were statistically analyzed, and factors that induced ARAPD were studied. Statistical analysis were performed according to the gender, nationality, occupation, age, weight, donation units, and number of donations. 【Results】 As to the factors inducing ARAPD, anticoagulant reactions accounted for the first(32.4%, 88/272). Women and students were prone to develop ARAPD. Among all age groups, 18~25 years old were most likely to develop ARAPD(53.68%, 10 572/35 265). The incidence of ARAPD were significantly different by ages and weights(P<0.05), and donors with lighter weight were more prone to develop ARAPD(P<0.05). The incidence of ARAPD were also significantly different between first-time and repeated donors(P<0.05), but not among the donation units. 【Conclusion】 The anticoagulant reactions are the leading reason for ARAPD. For female, student, young, light-weight, and first-time blood donors, special attention should be paid and corresponding interventions taken to them.
