Effects on the recruitment of inactive and lapsing blood donors, Questionnaire study based on motivators and deterrents / 中国输血杂志

ABSTRACT

【Objective】 To explore the effect of questionnaires on the re-recruitment of lapsed blood donors, and to ensure the retention of regular blood donors for blood supply in blood stations. 【Methods】 Blood Donation Motivation Questionnaire and Blood Donation Deterrents Questionnaire were designed for inactive and lapsing blood donors to inquire the motivation of the latest blood donation, such as "blood donation can save lives" and the reasons for no longer participating in blood donation, such as "there are no blood donation sites nearby", respectively. 13 093 blood donors with donation frequency ≥3 times and last donation during January 1 to May 17, 2018 in Guangzhou were selected as subjects. Text messages containing the links to the correspondent electronic questionnaires were sent to intervention group 1 (n=4 364) to fulfill the Blood Donation Motivation Questionnaire and intervention group 2 (n=4364) to fulfill Blood Donation Deterrents Questionnaire from May 18 to 25, 2020. None questionnaire was issued to the control group (n=4 365). The re-donation rates in the three groups within 2 months after the questionnaire delivery were analyzed by intention to treat (ITT) analysis and average treatment effect (ATT) estimation. 【Results】 The response rate of valid questionnaires was 5.422% (710/13 093), of which 7.424% (324/4 364) were in intervention group 1 and 8.845% (386/4 364) in intervention group 2. The collected questionnaire showed that the score of "blood donation can save lives" was the highest (2.31±0.79)in intervention group 1, and the score of "no blood donation site nearby" was the highest (2.31±0.80). in intervention group 2.2 months of observation showed that the re-donation rate was similar among all three groups by ITT analysis (Ps>0.05). ATT estimation results showed that the re-donation rates of intervention group 1 and intervention group 2 were 5.56%(18/324) and 3.11%(12/386), respectively(P<0.05). 【Conclusion】 Motivation questionnaire is a simple and convenient way to remind blood donors who have multiple donations to donate blood again.
