Blood transfusion is always associated with some level of risk. Haemovigilance is a risk monitoring system integral to the practice of transfusion medicine whose ultimate purpose is to improve the quality and safety of transfusion therapy.
To examine the contribution of haemovigilance to blood safety, including the approaches that some countries have taken to institute haemovigilance, and explore routes through which countries without such systems can achieve them.
The internet and journals on the topic of haemovigilance and development of haemovigilance systems in the English language.
Reputable journals on the topic of haemovigilance were examined for abstracts and papers. Abstracts based on known credible and distinguished sources were selected.
Information on haemovigilance and the processes of developing haemovigilance in various countries was reviewed.
The information from selected papers and abstracts was used for writing this paper.
Varying processes for haemovigilance have been adopted by different countries. The more advanced systems have national/regional coordinating mechanisms. Availability of haemovigilance data has given transfusion services a clear understanding of problems associated with transfusion that need to be solved so as to improve transfusion safety. Although countries in sub-Saharan Africa have made considerable progress in enhancing blood safety in the recent past, nationally coordinated haemovigilance systems are lacking. Focus on haemovigilance systems is considered the next frontier to be conquered in enhancing blood safety in the region.
输血总是伴随着一定程度的风险。血液警戒是输血医学实践中不可或缺的风险监测系统，其最终目的是提高输血治疗的质量和安全性。
探讨血液警戒对血液安全的贡献，包括一些国家建立血液警戒的方法，并探索没有此类系统的国家实现血液警戒的途径。
互联网以及关于血液警戒和血液警戒系统发展的英文期刊。
查阅了关于血液警戒主题的知名期刊的摘要和论文。选择了基于已知可靠和杰出来源的摘要。
审查了各国关于血液警戒及建立血液警戒过程的信息。
所选论文和摘要中的信息用于撰写本文。
不同国家采用了不同的血液警戒流程。更先进的系统设有国家/区域协调机制。血液警戒数据的可用性使输血服务机构能够清楚了解与输血相关的需要解决的问题，从而提高输血安全性。尽管撒哈拉以南非洲国家近年来在提高血液安全方面取得了相当大的进展，但缺乏国家协调的血液警戒系统。关注血液警戒系统被认为是该地区在提高血液安全方面有待攻克的下一个前沿领域。
