The evaluation of blood donor deferrals at Police General Hospital

Abstract

Background : Blood donor selection contributes to the safety of both donors and the recipients. The objective of this study was to identify the number and causes of blood donor deferrals. Also the growing trend of the causes of deferrals was studied. The data of this study will be used to reduce blood donor deferral rate.

Methods : A retrospective review of blood donor deferrals was studied at The Police General Hospital during January 2008 to June 2009. Blood donor deferrals were analyzed depending on age, donor groups, type of donor and causes of blood donor deferrals.

Results : Blood donor deferral rates during January 2008 to June 2009 were 26.2% and 27.1%, respectively. Blood donors aged during 31-40 years were the highest deferral group (2008 = 32.8%, 2009 = 38.4%). The repeated blood donors were deferred more than first-time blood donors. Female blood donors were deferred more than male blood donors. Main cause of blood donor deferral was low hemoglobin level (2008 = 21.9%, 2009 = 38.4%). After iron supplement, we found that 12 of 13 deferred donors with anemia were able to blood donate. However, one first-time blood donor had no change in hemoglobin level and was suggested not to donate blood.

Conclusions : This study showed that the growing trend of the causes of deferrals was low hemoglobin level. Regular blood donors should be encouraged to ensure regular post-donation iron supplement and health care suggestion of meals providing iron to prevent depletion of iron store which leads to anemia. The efficacy of blood donation management will recruit regular repeated donors, and will also increases amount of donated blood.
