本研究的目的是评估临床数据字典（CiDD）的内容覆盖率和数据质量的中心互操作EHR（CiEHR）。从一家拥有500张床位的三级癌症中心医院的98份临床表格中收集了12，994个术语。经过数据清理后，研究团队将9，418个术语与CiDD的数据项进行了映射，并由研究医院的30名医生和护士进行了验证。映射结果分为五类：词汇映射;语义映射;映射到一个更广泛的术语或一个更狭窄的术语;映射到一个以上的术语和未映射。在覆盖范围方面，在9 418个术语中，6 750个术语（71.7%）项被映射; 4，319（45.9%）词汇映射; 2，431（25.8%）进行了语义映射;（3.0%）项被映射到更广泛的术语; 43项（0.5%）被映射到更窄的术语; 550项（5.8%）被映射到一个以上的术语。在数据质量方面，CiDD存在概念命名和表示错误、同义词冗余、同义词不足和含义模糊等问题。虽然CiDD的术语覆盖了72%的本地临床术语，但可以通过清理错误和冗余、添加概念的文本定义或用例以及将概念排列成层次结构来改进CiDD。
The purpose of the study was to evaluate content coverage and data quality of the Clinical Data Dictionary (CiDD) developed by the Center for Interoperable EHR (CiEHR). A total of 12,994 terms were collected from 98 clinical forms of a tertiary cancer center hospital with 500 beds. After data cleaning, 9,418 terms were mapped with the data items of the CiDD by the research team, and validated by 30 doctors and nurses at the research hospital. Mapping results were classified into five categories: lexically mapped; semantically mapped; mapped to either a broader term or a narrower term; mapped to more than one term and not mapped. In terms of coverage, out of 9,418 terms, 6,750 (71.7%) terms were mapped; 4,319 (45.9%) terms were lexically mapped; 2,431 (25.8%) were semantically mapped; 281 (3.0%) terms were mapped to a broader term; 43 (0.5%) were mapped to a narrower term; and 550 (5.8%) were mapped to more than one term. In terms of data quality, the CiDD has problems such as errors in concept namingand representation, redundancy in synonyms, inadequate synonyms, and ambiguity in meaning. Although the CiDD has terms covering 72% of local clinical terms, the CiDD can be improved by cleaning up errors and redundancies, adding textual definitions or use cases of the concept, and arranging the concepts in a hierarchy.
