越来越需要基于标准、可计算的资格标准知识表示,为自动研究参与者筛选、临床证据应用和临床研究知识管理提供基于计算机的决策支持。我们调查了文献并确定了有助于各种研究和临床应用的资格标准知识表示的五个方面:可计算资格标准的预期用途、资格标准的分类、表示资格规则的表达语言、资格概念的编码以及患者数据的建模。我们认为其中三个(表达语言、资格概念的编纂和患者数据建模)是资格标准的正式知识表示的基本构造。对于不同的用例,这三种知识结构的要求各不相同,因此,这应该为结构的开发和选择提供信息,以实现具有成本效益的知识表示工作。我们讨论了我们的研究结果对资格标准的可共享知识表示的标准化工作的影响。
Standards-based, computable knowledge representations for eligibility criteria are increasingly needed to provide computer-based decision support for automated research participant screening, clinical evidence application, and clinical research knowledge management. We surveyed the literature and identified five aspects of eligibility criteria knowledge representations that contribute to the various research and clinical applications: the intended use of computable eligibility criteria, the classification of eligibility criteria, the expression language for representing eligibility rules, the encoding of eligibility concepts, and the modeling of patient data. We consider three of them (expression language, codification of eligibility concepts, and patient data modeling), to be essential constructs of a formal knowledge representation for eligibility criteria. The requirements for each of the three knowledge constructs vary for different use cases, which therefore should inform the development and choice of the constructs toward cost-effective knowledge representation efforts. We discuss the implications of our findings for standardization efforts toward sharable knowledge representation of eligibility criteria.
