“…Two options are available to reduce the observational effect: (a) Reduce the number of donors fainting, and (b) reduce the visibility of donors fainting. Reducing the number of donors fainting could be achieved by either screening for risk factors (e.g., Ditto, Adler, France, & France, 1995; France, 1995; Labus, France, & Taylor, 2000; Trouern-Trend, Cable, Badon, Newman, & Popovsky, 1999) or using prophylactic interventions (e.g., Sauer & France, 1999). Simply rearranging the donor site using screens to partition areas should reduce visibility.…”

A prospective design was used to explore the efficacy of 6 factors (e.g., intentions) to predict the number of future blood donations in an initial sample of 630 blood donors. Differential predictions are made for the roles of past behavior and intentions with respect to occasional (4 or fewer previous blood donations) and regular (5 or more previous blood donations) blood donors. Intentions were predictive for occasional donors, and past behavior was predictive for regular donors. Furthermore, for regular donors only, an inverted U-shaped curve explained the relationship between past behavior and future behavior. Finally, it is reported that observing others fainting produces a reduction in the number of future donations for occasional donors. The theoretical and practical implications of these findings are discussed.

“…Donor inexperience may be one important factor that may contribute to vasovagal responses during blood donation. For example, it has been shown that nurses obtaining blood from inexperienced donors without a parental history of hypertension were significantly more likely to recline the subject's chair than those obtaining blood from inexperienced donors with a parental history of hypertension or experienced donors (Ditto, Adler, France, & France, 1995). Generally, less experienced blood donors reported more vasovagal symptoms than experienced donors, and this corresponds to higher rates of treatment by the nurses, more fainting, and fewer full units of blood obtained (Byrne & Ditto, 2005).…”

Vasovagal Syncope and Blood Donor Return: Examination of the Role of Experience and Affective Expectancies

Vasovagal sensations (e.g., dizziness, nausea, and fainting) are one of the main reasons people find blood donation unpleasant. A better understanding of predictors of vasovagal sensations during blood donation could inform interventions designed to increase donor return rates. The present investigation examined the extent to which experience with blood donation and vasovagal sensations during blood donation uniquely predict the likelihood of donor return, even when controlling for affective expectancies. Participants presenting at community blood drives indicated how many times they have given blood and provided ratings of expected anxiety, pain, disgust, as well as fear of fainting before giving blood. After donating, participants completed a measure of vasovagal sensations experienced during blood donation. They also rated the pleasantness of the experience and willingness to donate blood in the future. The findings showed that experience with blood donation and vasovagal sensations during blood donation uniquely predicted willingness to donate blood in the future even when controlling for age and negative affective expectancies about giving blood. This finding suggests that vasovagal sensations and experience with blood donation have unique (and perhaps additive) effects on willingness to donate blood in the future, suggesting that behavior modification interventions that directly target these variables could potentially increase donor retention.

Disponer de un flujo suficiente de donantes altruistas que permita la obtención de componentes sanguíneos de buena calidad es el problema más importante en los bancos de sangre en nuestro medio. La presencia de reacciones adversas a la donación puede influir en forma negativa en la disposición del donante para regresar al banco de sangre. Con el objetivo de establecer la frecuencia y explorar los factores de riesgo involucrados en la aparición de reacciones adversas a la donación, se realizó un estudio de corte, basado en los registros de donantes del Banco de Sangre de la Clínica Cardiovascular Santa María de Medellin durante 1999. La edad promedio de los donantes estudiados fue de 33 años en mujeres y 34 en hombres; se encontró una frecuencia de reacciones adversas de 2,7% y la predominante fue la reacción vasovagal con el 1,2%. Los posibles factores de riesgo relacionados con las reacciones adversas, en general, fueron donación por primera vez, edad menor de 25 años y sexo femenino. Los bancos de sangre tienen la responsabilidad de establecer estrategias para prevenir y detectar precozmente la presencia de reacciones adversas en los donantes que acuden a sus instalaciones. Factores como el entrenamiento del personal, el trato dado al donante durante todo el proceso, el ambiente y la selección del sitio de la punción, entre otros, juegan un papel importante en la aparición de reacciones adversas. Con el objetivo de establecer la frecuencia e identificar las causas
