RESUMO
We created a questionnaire in order to understand why donors generally did not want to give plasma and platelets the first time they were asked to donate. The hypothesis is that donors have a negative perception of hemapheresis due to insufficient information about procedures and emocomponent use. We collected 745 Questionnaires in the Marche and Abruzzo regions from February to April 2001. Results show that donors have an unfavourable perception of the hemapheresis compared to blood donation. We found differences in donors' perception between all kinds of donations regarding these aspects: (1) information about donation procedures, (2) awareness of emocomponent use, (3) importance of different kinds of donation, (4) availability of donors in relation to length of donations, (5) level of safety (regarding the possibility to contracting some viruses and also regarding possible immediate side-effects), (6) level of importance for saving lives. A key factor in determining an unfavourable perception of hemapheresis is the information level; in fact we found by linear regression that the information level affects the perception of safety and donation importance. These differences of perception show that there are prejudices about hemapheresis which are caused by a lack of Information. So we are convinced, also by statistical analysis, that better information is the most effective way to increase hemapheresis.
