Factors influencing the returning of plateletpheresis donors / 中国输血杂志

ABSTRACT

【Objective】 To explore and analyze on the factors that influence the returning of plateletpheresis donors. 【Methods】 A total of 1 302 plateletpheresis donors, selected from 2014 to 2020 in the blood center, were followed up for 1 year, and their re-donations were recorded. The data of factors were analyzed through Univariate analysis and Logistic regression on statistical software. 【Results】 From 2014 to 2020, there were 1 302 donors participated first-time plateletpheresis donation, including 1070 males and 232 females, aged 18-55 years old, with an average age (28.69±12.90) of years old. As to the education level, 539 cases were junior high school education level and below, 435 cases senior school or technical secondary school education level, and 328 cases junior college education level and above. Within the 1 302 first-time platelet donors, 16 developed adverse reactions to blood donation. 455 donors donated one dose, and 847 cases donated two doses. 506 were public or permanent employed, and 796 were unemployed. 1 267 were ethnic Hans and 35 were ethnic minorities. 21.81%(284/1 302) returned to donate within one year. Univariate and multivariate Logistic regression analysis showed that gender, age, educational level, whether suffered adverse reactions during the first-time donation, doses of donation, ethnicity and occupations all affected the returning of plateletpheresis donors. 【Conclusion】 Plateletpheresis donors with younger age, lower education level, unemployed status, ethnic minorities, no adverse reactions occurring during the first-time donation, and donation history of two doses are more likely to return to donate.
