title: A questionnaire: will plateletpheresis donors accept multicomponent donation?
abstract: OBJECTIVE
  New technological developments make it possible to collect red blood cells (RBC) by apheresis which provides standardised products and has the potential for improved RBC quality. The purpose of this study was to evaluate the donors' opinion about the multicomponent donation procedure.
  
  
  METHODS
  For evaluating the donors' opinion about this new apheresis technique we compiled a questionnaire. The questionnaire was given to all single needle actual plateletpheresis donors (n = 133) that donated platelets in our Institute during February-March 2001. The questionnaire contained 12 questions related to: (1) general information about previous donations of our donors and (2) donors' opinion about multicomponent donation. After implementation of multicomponent donation in December 2001 the data of the questionnaire were compared with the actual opinions of the donors about the procedure.
  
  
  RESULTS
  The mean age of the donors was 38.1 +/- 9.1 years. The median number of previous platelets donations of the interviewed donors was 30. The majority of donors (92.4%) were willing for multicomponent donation. In the same time the majority of donors (74.8%) were willing to donate multicomponents four times per year. The different donation time was not an argument for the donors for the multicomponent donation, while the reduction of incidence of transfusion transmitted diseases was a motivation for them. The decrease of hemoglobin and the side effects caused by possible iron-supplementation therapy were found acceptable from most of our donors. Approximately 74% of the donors thought that the donation of a second component should result in better remuneration whereas 20% of them believed that the remuneration should be unchanged. Seventy-five RBC units were concurrently collected with platelets since December 15th, 2001. Six donors (7.4%) were unwilling to donate an additional RBC unit.
  
  
  CONCLUSIONS
  Acceptance and disacceptance rates were almost equal after the implementation of multicomponent donation and at the time point when the interview was performed. The majority of donors was highly motivated to donate multicomponents, by these means we were able to increase our RBC supply and to improve standardization of our products.
