目的描述和评价参与健康信息交换（HIE）的40家医院的计算机断层扫描（CT）术语到标准术语的映射。方法从2013年1月至2015年10月向HIE传输放射学数据的40个HIE参与者站点获取专有CT检查术语和相应的检查频率数据。从2016年1月开始，使用Regenstrief LOINC映射助手（RELMA）将这些术语映射到逻辑观测标识符名称和代码（LOINC®）术语。没有初始LOINC匹配的条款将作为持续的新条款请求提交给LOINC。在创建新的LOINC术语之后，检查没有初始匹配的专有术语，并在适当的地方将其映射到这些新的LOINC术语。内容类型和令牌覆盖率是针对初始映射时的LOINC版本（v2.54）和我们进行分析时最新发布的版本（v2.63）计算的。进行描述性分析以评估两个版本之间内容相关覆盖率的显著差异。结果sloinc 2.54版本的HIE CT考试术语的内容类型和token覆盖率分别为83%和95%。在2.54和2.63版本发布之间，创建了215个新的LOINC CT术语，内容类型和令牌覆盖率分别增加到93%和99% （P< 0.001）。结论loinc在40个HIE网站中专有CT术语的内容类型覆盖率为83%，但在创建新术语后显着提高到93%。
ObjectiveWe describe and evaluate the mapping of computerized tomography (CT) terms from 40 hospitals participating in a health information exchange (HIE) to a standard terminology.MethodsProprietary CT exam terms and corresponding exam frequency data were obtained from 40 participant HIE sites that transmitted radiology data to the HIE from January 2013 through October 2015. These terms were mapped to the Logical Observations Identifiers Names and Codes (LOINC®) terminology using the Regenstrief LOINC mapping assistant (RELMA) beginning in January 2016. Terms without initial LOINC match were submitted to LOINC as new term requests on an ongoing basis. After new LOINC terms were created, proprietary terms without an initial match were reviewed and mapped to these new LOINC terms where appropriate. Content type and token coverage were calculated for the LOINC version at the time of initial mapping (v2.54) and for the most recently released version at the time of our analysis (v2.63). Descriptive analysis was performed to assess for significant differences in content-dependent coverage between the 2 versions.ResultsLOINC’s content type and token coverages of HIE CT exam terms for version 2.54 were 83% and 95%, respectively. Two-hundred-fifteen new LOINC CT terms were created in the interval between the releases of version 2.54 and 2.63, and content type and token coverages, respectively, increased to 93% and 99% (P< .001).ConclusionLOINC’s content type coverage of proprietary CT terms across 40 HIE sites was 83% but improved significantly to 93% following new term creation.
