A Web-based approach to blood donor preparation.

BACKGROUND: Written and video approaches to donor education have been shown to enhance donation attitudes and intentions to give blood, particularly when the information provides specific coping suggestions for donation-related concerns. This study extends this work by comparing Web-based approaches to donor preparation among donors and nondonors. STUDY DESIGN AND METHODS: Young adults (62% female; mean [±SD] age, 19.3 [±1.5] years; mean [range] number of prior blood donations, 1.1 [0-26]; 60% nondonors) were randomly assigned to view 1) a study Web site designed to address common blood donor concerns and suggest specific coping strategies (n = 238), 2) a standard blood center Web site (n = 233), or 3) a control Web site where participants viewed videos of their choice (n = 202). Measures of donation attitude, anxiety, confidence, intention, anticipated regret, and moral norm were completed before and after the intervention. RESULTS: Among nondonors, the study Web site produced greater changes in donation attitude, confidence, intention, and anticipated regret relative to both the standard and the control Web sites, but only differed significantly from the control Web site for moral norm and anxiety. Among donors, the study Web site produced greater changes in donation confidence and anticipated regret relative to both the standard and the control Web sites, but only differed significantly from the control Web site for donation attitude, anxiety, intention, and moral norm. CONCLUSION: Web-based donor preparation materials may provide a cost-effective way to enhance donation intentions and encourage donation behavior.

Assessment of donor fear enhances prediction of presyncopal symptoms among volunteer blood donors.

BACKGROUND: 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. STUDY DESIGN AND METHODS: 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. RESULTS: 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. CONCLUSION: 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.
