Fear of blood donation is implicated in vasovagal reactions, donor recruitment, and retention. This study examined the extent to which fear among donors is associated with various donor outcomes in an Australian sample, and whether fear can be addressed on-site to reduce adverse reactions and improve the donation experience.
Six hundred and sixty-four donors (age M = 33.4, SD = 12.7; 55% female) participated in a two-center, pragmatic, parallel group, individually randomized controlled trial. Following donor registration and consent, whole-blood (n = 539) and plasma (n = 125) donors were assigned to one of four Conditions: control; fear assessment; fear assessment + brochure; fear assessment + brochure + tailored conversation focused on any self-reported fear and coping strategies. Post-donation questionnaires assessed the donors' experience including positive support, donor self-efficacy, anxiety, fear, venipuncture pain, and vasovagal reactions.
Fear among donors predicted higher venipuncture pain, post-donation anxiety, and vasovagal reactions and remained significant after controlling for other established predictors (i.e., total estimated blood volume, age, sex, and donation experience). Mediational analyses showed that exposure to brochures (with or without the tailored conversation) was associated with less pain, with this effect mediated by donor perceptions of more positive support. Venipuncture pain was also associated with vasovagal reactions, reduced likelihood of return within 6 months, and less satisfaction with the donation experience.
The current results underline the importance of interventions to address fear among both whole-blood and plasma donors to secure the safety and well-being of donors and the blood supply.
对献血的恐惧与血管迷走神经性反应、招募和保留献血者有关。本研究在澳大利亚样本中检查了献血者的恐惧程度与各种献血者结果的关联,以及是否可以在现场解决恐惧问题,以减少不良反应并改善献血体验。
664 名献血者(年龄 M=33.4,SD=12.7;55%为女性)参与了一项两中心、实用、平行组、个体随机对照试验。在献血者登记和同意后,全血(n=539)和血浆(n=125)献血者被分配到以下四种条件之一:对照组;恐惧评估;恐惧评估+小册子;恐惧评估+小册子+针对任何自我报告的恐惧和应对策略的个性化谈话。献血后问卷调查评估了献血者的体验,包括积极支持、献血者自我效能、焦虑、恐惧、静脉穿刺疼痛和血管迷走神经性反应。
献血者的恐惧预测更高的静脉穿刺疼痛、献血后焦虑和血管迷走神经性反应,并且在控制其他既定预测因素(即总估计血容量、年龄、性别和献血经验)后仍然显著。中介分析表明,接触小册子(有或没有个性化谈话)与疼痛减轻相关,这种效果由献血者对更积极支持的看法所介导。静脉穿刺疼痛也与血管迷走神经性反应、降低 6 个月内再次献血的可能性以及对献血体验的满意度降低有关。
目前的结果强调了干预措施的重要性,以解决全血和血浆献血者的恐惧,以确保献血者的安全和福祉以及血液供应。
