Abstrakt: Background: This longitudinal study of high school whole blood donors examined relationships among donation-related fears assessed prior to donation, vasovagal reactions to donation, and the proportion of donors who attempted another donation over the subsequent 60 weeks.
Study Design and Methods: Data regarding vasovagal reactions and attempted donation were obtained from donor records of 530 female and 342 male high school donors who answered questions about five types of fear (ie, of blood draw, needles, seeing blood, feeling pain, or fainting) prior to their index donation.
Results: Each type of fear was associated with an increased risk of vasovagal reactions (all P < .001) and a smaller percentage of attempted donations was seen among those who reported at least one type of fear (53%) as compared to those who did not report any fear (62.1%); P = .022; β = -0.374, OR = 0.69; 95% CI, 0.50-0.94. Path analyses of the relationships among fear, vasovagal reaction, and attempted donation revealed significant indirect effects for each type of fear. Specifically, donors who reported fear were at increased odds of experiencing a vasovagal reaction, which, in turn, was associated with decreased odds of attempting a repeat donation.
Conclusion: Donation-related fears are associated with reduced donor return rates, and this effect is mediated through an increased risk for vasovagal reactions. For both practical and ethical reasons, blood collectors are encouraged to identify and intervene with fearful donors to reduce the likelihood of negative donation-related symptoms and enhance donor retention.
