Knowledge and attitudes of apheresis donors regarding apheresis blood donation

Demand for apheresis blood donation has increased with the widening of the use of blood transfusion and the decrease in the donor pool. The knowledge level of apheresis donors, their attitudes such as donating again and recommending others to donate via apheresis are important in meeting this demand.

This analytical cross-sectional study was conducted with 182 plateletpheresis donors to determine their knowledge and attitudes regarding apheresis blood donation.

Participants were asked 34 questions (which were prepared based on the literature and perfected by expert opinion and pre-administration) to determine their level of knowledge regarding apheresis. A value of 1 point was assigned for each 'correct' answer and 0 points for 'wrong' and 'do not know' answers. Participants' total level of knowledge scores was formulated to have a value between 0 and 100 (i.e., the score of each group was divided into the number of question and multiplied by 100). Participant attitudes were evaluated based on responses to 14 questions using a 5-point Likert questionnaire.

Total knowledge scores regarding apheresis were moderate (55 ± 15.2). Those who were educated above the university level (compared to primary school and less, middle and high-school education levels) had higher level of knowledge scores regarding apheresis. In general, participants had a positive attitude regarding the importance and effects of apheresis blood donation. Those with the following characteristics had a positive attitude (p < 0.05) regarding the importance of apheresis blood donation: female (compared to men), single (compared to married), 18-33 years of age (compared to 34-49 and 50-65 years of age groups, with an above-university level of education (compared to primary school and less, middle and high-school education levels), informed regarding apheresis blood donation, first-time donors and donors to unknown recipients.

Study participants demonstrated a moderate level of knowledge and positive attitude regarding the importance of apheresis blood donation. Thus, to enhance attitudes on the procedure and reduce the risk of recipient infections, blood donors should be better informed regarding apheresis blood donation.
