The contention of the author is that an informatics infrastructure is essential for evidenced-based practice. Five building blocks of an informatics infrastructure for evidence-based practice are proposed: 1) standardized terminologies and structures, 2) digital sources of evidence, 3) standards that facilitate health care data exchange among heterogeneous systems, 4) informatics processes that support the acquisition and application of evidence to a specific clinical situation, and 5) informatics competencies. Selected examples illustrate how each of these building blocks supports the application of evidence to practice and the building of evidence from practice. Although a number of major challenges remain, medical informatics can provide solutions that have the potential to decrease unintended variation in practice and health care errors.
作者的论点是，信息学基础设施对于循证实践至关重要。文中提出了循证实践信息学基础设施的五个组成部分：1）标准化术语和结构；2）证据的数字来源；3）促进异构系统间医疗数据交换的标准；4）支持在特定临床情况下获取和应用证据的信息学流程；5）信息学能力。通过选取的示例来说明这些组成部分中的每一个是如何支持将证据应用于实践以及从实践中构建证据的。尽管仍存在一些重大挑战，但医学信息学可以提供有可能减少实践中意外差异和医疗差错的解决方案。
