Application of information technology may increase the efficacy of Confidential Unit Exclusion (CUE) in blood donors.

Confidential Unit Exclusion (CUE) refers to a procedure by which a blood donor designates confidentially whether his or her blood might not be safe for transfusion. It applies to situations in which an individual who is not eligible for blood donation in terms of blood safety feel pressured by others to donate his or her blood. A potential problem in the CUE system is misunderstanding of the procedure and its significance by blood donors as well as the lack of their confidence regarding the confidentiality of their private information. Since the Information and Communication Technology (ICT) provides a secure and confidential atmosphere, it is expected the application of ICT have a positive impact on the efficacy of CUE system.
