The goal of selecting a healthy blood donor is to safeguard donors and reduce the risks of infections and immunologic complications for recipients.
To evaluate the blood donor selection process, a survey was conducted in 28 blood transfusion centers located in 15 francophone African countries. Data collected included availability of blood products, risk factors for infection identified among blood donor candidates, the processing of the information collected before blood collection, the review process for the medical history of blood donor candidates, and deferral criteria for donor candidates.
During the year 2009, participating transfusion centers identified 366,924 blood donor candidates. A mean of 13% (range, 0%-36%) of the donor candidates were excluded based solely on their medical status. The main risk factors for blood-borne infections were having multiple sex partners, sexual intercourse with occasional partners, and religious scarification. Most transfusion centers collected this information verbally instead of having a written questionnaire. The topics least addressed were the possible complications relating to the donation, religious scarifications, and history of sickle cell anemia and hemorrhage. Only three centers recorded the temperature of the blood donors. The deferral criteria least reported were sickle cell anemia, piercing, scarification, and tattoo.
The medical selection process was not performed systemically and thoroughly enough, given the regional epidemiologic risks. It is essential to identify the risk factors specific to francophone African countries and modify the current medical history questionnaires to develop a more effective and relevant selection process.
选择健康献血者的目的是保护献血者,降低受血者感染和免疫并发症的风险。
为了评估献血者选择过程,在 15 个法语非洲国家的 28 个输血中心进行了一项调查。收集的数据包括血液制品的供应情况、献血者候选人中感染的危险因素、献血前收集的信息处理情况、献血者候选人的病史审查流程以及献血者候选人的延期标准。
在 2009 年,参与的输血中心共识别了 366924 名献血者候选人。平均有 13%(范围,0%-36%)的献血者候选人仅因医疗状况而被排除。血液传播感染的主要危险因素是有多个性伴侣、与偶然伴侣发生性关系和宗教割礼。大多数输血中心都是口头收集这些信息,而不是通过书面问卷。涉及的主题最少的是与献血相关的可能并发症、宗教割礼以及镰状细胞贫血和出血史。只有三个中心记录了献血者的体温。报告的延期标准最少的是镰状细胞贫血、穿孔、割礼和纹身。
鉴于该地区的流行病学风险,医疗选择过程没有系统和彻底地进行。必须确定特定于法语非洲国家的风险因素,并修改当前的病史问卷,以制定更有效和相关的选择过程。
