One of the core elements of antibiotic stewardship is surveillance and monitoring of quantity of antibiotic use. This requires tools for measuring the quantity of antibiotic use. However, these metrics have not been standardized, and different metrics are used across different countries, regions and individual healthcare settings. In the literature, there is much controversy on the most appropriate metric for monitoring antibiotic use. Several authors have questioned the relevance of DDDs, which are recommended by the WHO, while others still prefer using DDDs as the best available metric. The results of the recent DRIVE-AB project suggest that a combination of metrics may be the best approach, since all metrics have limitations and provide different perspectives.

评估抗生素使用量最合适的指标是什么？

抗生素管理的核心要素之一是对抗生素使用量的监控。这需要用于测量抗生素使用量的工具。但是，这些指标尚未标准化，并且在不同的国家，地区和个人医疗机构中使用了不同的指标。在文献中，关于监测抗生素使用的最合适指标存在很多争议。几位作者质疑了DDD的相关性，这是WHO推荐的，而另一些作者仍然更喜欢使用DDD作为最佳的可用度量。最近的DRIVE-AB项目的结果表明，将指标组合在一起可能是最好的方法，因为所有指标都有局限性并提供不同的观点。
