The National Emergency Medical Services (EMS) Information System (NEMSIS) Technical Assistance Center (TAC) collects and curates EMS activation level records for the United States. Originated as an outcomes assessment and service comparison tool, NEMSIS may have other high value clinical and public health uses.
This study acquired a 100% activation level public dataset for 2019 from NEMSIS TAC and assessed item response quantities. Subsumption of NEMSIS terms within other controlled clinical vocabularies was also considered.
None of the assessed terminologies (LOINC, ICD10-CM, SNOMED-CT) could describe meaningful volumes of NEMSIS item response codes. The 2019 activation year dataset included 36,525 non-date/time or calculated distinct item responses for 43 activation descriptive items. Said item responses yielded 2,101,844,053 activation distinct non-blank responses. Several NEMSIS item responses had high clinical and public health value.
NEMSIS can support multiple public health use cases in addition to EMS outcomes assessment. A comprehensive custom value set is appropriate to integrate NEMSIS item response codes into controlled terminologies, FHIR or hospital Electronic Health Record applications.
国家紧急医疗服务（EMS）信息系统（NEMSIS）技术援助中心（TAC）收集并整理美国的EMS启动级别记录。NEMSIS最初是作为一种结果评估和服务比较工具，可能还有其他高价值的临床和公共卫生用途。
本研究从NEMSIS TAC获取了2019年100%的启动级别公共数据集，并评估了项目响应数量。还考虑了将NEMSIS术语纳入其他受控临床词汇表的情况。
所评估的术语（LOINC、ICD10-CM、SNOMED-CT）均无法描述有意义数量的NEMSIS项目响应代码。2019年启动年份数据集包括针对43个启动描述性项目的36,525个非日期/时间或计算得出的不同项目响应。上述项目响应产生了2,101,844,053个启动不同的非空白响应。若干NEMSIS项目响应具有较高的临床和公共卫生价值。
除了EMS结果评估外，NEMSIS还可支持多个公共卫生用例。一个全面的定制值集适合将NEMSIS项目响应代码集成到受控术语、FHIR或医院电子健康记录应用程序中。
