目的 在使用SNOMED CT对临床研究概念进行编码时,比较代表三家商业编码服务提供商的专业SNOMED CT编码器之间的编码一致性。 设计 由NIH资助的罕见疾病临床研究网络(RDCRN)生成的病例报告表(CRF)中的临床研究问题样本被发送给三家编码公司,并说明使用SNOMED CT编码核心概念。样本包括来自15个独立研究的319个问题/答案对。要求这些公司选择能够反映问题中核心概念的SNOMED CT概念(任何形式,包括后协调)。此外,他们被要求陈述他们的确定性水平,以及他们认为他们的编码有多精确。 测量 计算基本频率以确定公司之间的原始水平一致性和其他描述性信息。Krippendorff的alpha被用来确定编码公司之间的几个指标(语义,确定性和精确度)的统计一致性。 结果 专家之间没有达成显著的一致意见。 结论 来自3家专业编码服务机构的编码人员在临床研究数据项编码方面几乎没有语义一致性,即使使用非常自由的一致性定义。
OBJECTIVE To compare consistency of coding among professional SNOMED CT coders representing three commercial providers of coding services when coding clinical research concepts with SNOMED CT. DESIGN A sample of clinical research questions from case report forms (CRFs) generated by the NIH-funded Rare Disease Clinical Research Network (RDCRN) were sent to three coding companies with instructions to code the core concepts using SNOMED CT. The sample consisted of 319 question/answer pairs from 15 separate studies. The companies were asked to select SNOMED CT concepts (in any form, including post-coordinated) that capture the core concept(s) reflected in the question. Also, they were asked to state their level of certainty, as well as how precise they felt their coding was. MEASUREMENTS Basic frequencies were calculated to determine raw level agreement among the companies and other descriptive information. Krippendorff's alpha was used to determine a statistical measure of agreement among the coding companies for several measures (semantic, certainty, and precision). RESULTS No significant level of agreement among the experts was found. CONCLUSION There is little semantic agreement in coding of clinical research data items across coders from 3 professional coding services, even using a very liberal definition of agreement.
