Transfusion committees have been created in different countries to oversee all aspects of blood product transfusion within individual institutions. A fundamental role of hospital transfusion committees is to ensure appropriate blood product use by developing local policies, educating clinicians, and auditing blood use. Unfortunately, this task is hampered by the lack of universally accepted criteria for blood product transfusion. Several examples of specific interventions directed toward improving blood use have been described in the literature. Despite some limitations of these reports, largely because of shortfalls in study design, such interventions appear to be generally effective, but there is not enough evidence to recommend a specific course of action to ensure appropriate blood use. Notwithstanding such problems, a functional hospital transfusion committee can have a major impact on local rates of inappropriate transfusion.

医院输血委员会在血液制品保存中的作用。

已经在不同国家成立了输血委员会，以监督各个机构内血液制品输血的各个方面。医院输血委员会的基本职责是通过制定地方政策，教育临床医生和审核血液使用情况来确保适当使用血液产品。不幸的是，由于缺乏普遍接受的血液制品输注标准，这项任务受到了阻碍。在文献中已经描述了针对改善血液使用的具体干预措施的几个例子。尽管这些报告存在某些局限性，主要是由于研究设计的不足，但这种干预措施总体上看似有效，但没有足够的证据推荐采取特定措施以确保适当用血的干预措施。尽管有这些问题，
