One of the objectives of predonation selection is to exclude blood donors with possible infection. Our aim was to evaluate the efficacy of the different blood donor selection techniques. The approach chosen for this review of literature was the best evidence synthesis. A bibliographic search was carried out to identify all articles on the subject published between 1986 and 1996 which presented quantitative results of evaluation. Only nine relevant studies were selected. These referred to self exclusion before interview, health history interview and confidential deferral after donation. None of the articles evaluated the physical examination. The results suggested an efficacy for self exclusion before interview. One study considered the blood donor selection and compared various ways of combining self exclusion before interview, health history interview and confidential deferral after donation. No combination emerged as more effective than the others. This analysis shows that the efficacy of predonation blood donor selection applied to transfusion transmitted infections has not been evaluated adequately. The different techniques of blood donor selection must be considered as public health actions and hence evaluated according to a rigorous methodology using valid criteria.
献血前筛选的目标之一是排除可能感染的献血者。我们的目的是评估不同献血者筛选技术的效果。本次文献综述所采用的方法是最佳证据综合法。进行了文献检索，以确定1986年至1996年间发表的所有关于该主题且呈现评估定量结果的文章。仅挑选出9项相关研究。这些研究涉及面试前自我排除、健康史询问以及献血后保密延期。没有文章对体格检查进行评估。结果表明面试前自我排除具有效果。一项研究考量了献血者筛选，并比较了面试前自我排除、健康史询问和献血后保密延期的各种组合方式。没有一种组合方式被证明比其他方式更有效。该分析表明，应用于输血传播感染的献血前筛选效果尚未得到充分评估。不同的献血者筛选技术必须被视为公共卫生行动，因此应根据严格的方法并使用有效标准进行评估。
