Fear is an important contributor to the risk of presyncopal reactions to blood donation. However, concern that asking donors about their fears may increase the risk of reactions is a potential impediment to incorporating fear assessment into donor screening.
Before donation, participants responded to a series of questions that either did (n = 488) or did not (n = 494) include questions related to fear of seeing blood drawn. Immediately after donation all participants provided ratings of presyncopal reactions.
Among those asked predonation fear questions, fear was most strongly related to presyncopal symptoms when compared against other donor characteristics (e.g., age, number of prior donations, body mass index, estimated blood volume, blood pressure, and pulse). However, Mann-Whitney U tests revealed that being asked about fear before donation was not associated with higher reports of presyncopal reactions for the sample as a whole, nor among novice donors. Further, regression analyses indicated that fear remained a significant predictor of presyncopal reactions in final models that included age and number of prior donations as significant predictors.
Predonation assessment of fear of blood draws may help to identify donors who are most likely to benefit from brief interventions designed to enhance donor coping, reduce risk of presyncopal reactions, and increase donor retention.
恐惧是导致献血前晕厥反应的重要因素。然而，担心询问献血者的恐惧可能会增加反应的风险，这可能会阻碍将恐惧评估纳入献血者筛选。
在献血前，参与者回答了一系列问题，其中一些问题（n=488）或不包括（n=494）与害怕看到采血有关的问题。在献血后，所有参与者立即对晕厥前反应进行了评分。
在那些被问到预献血恐惧问题的人中，与其他献血者特征（如年龄、之前献血次数、体重指数、估计血容量、血压和脉搏）相比，恐惧与晕厥前症状的关系最为密切。然而，曼-惠特尼 U 检验显示，在整个样本中，以及在新手献血者中，在献血前询问恐惧与更高的晕厥前反应报告并无关联。此外，回归分析表明，在包括年龄和之前献血次数作为显著预测因子的最终模型中，恐惧仍然是晕厥前反应的显著预测因子。
预献血时对采血恐惧的评估可能有助于识别最有可能从旨在增强献血者应对能力、降低晕厥前反应风险和增加献血者保留率的简短干预中受益的献血者。
