  • The National Emergency Medical Services Information System (NEMSIS) provides a universal standard for the collection and transmission of emergency medical services (EMS) patient care data. NEMSIS data is collected by EMS practitioners at the point of care and includes patient demographics, medical treatment provided, and EMS response times. NEMSIS includes the National EMS Database which accepts EMS data voluntarily submitted by U.S. States and Territories. NEMSIS requires local EMS systems to collect a national set of data elements for submission to the National EMS Database through their respective state. Local EMS systems have the option to collect additional NEMSIS data elements to meet local needs.
  • NEMSIS uses Extensible Markup Language (XML) to move data. States and software companies create products that are used to send and receive EMS data in the proper XML format from agencies to states, then on to the National EMS Database. More information about NEMSIS is available at https://nemsis.org/technical-resources/.
  • Mapping and translation resources are available for mapping or translating older versions of the dataset to newer versions of the dataset.

We concur that the NEMSIS data set is an important collector of variables in the EMS context. In addition, we note that LOINC contains terms for observations and observation values for the complete NEMSIS data set (see panel 84428-2). Additionally, HL7 has developed the HL7 Version 3 Implementation Guide for CDA Release 2 - Level 3: Emergency Medical Services; Patient Care Report, Release 2 - US Realm, which uses the LOINC observation and observation values codes. http://www.hl7.org/implement/standards/product_brief.cfm?product_id=438

Further, it may also be worth mentioning that there is correlation between the NEMSIS (pre-hospital) data elements and the National Trauma Data Bank (NTDB) data dictionary, with the idea that the trauma registry could be “auto-populated” with the subset of relevant prehospital data. The National Trauma Data Standard data dictionary (2018 version) is also represented in LOINC (see panel 87825-6). HL7 has developed the HL7 CDA® R2 Implementation Guide: Trauma Registry Data Submission, Release 1 - US Realm, which uses LOINC. http://www.hl7.org/implement/standards/product_brief.cfm?product_id=355.

Last, the German Interdisciplinary Association of Intensive Care and Emergency Care Medicine defined a data set to enable efficient exchange from EMS pre-hospital services to receiving institutions. This complete data set of variables in the rescue service protocols are represented in LOINC (see panel 88677-0). This further supports the use of LOINC as a code system for use in this context.
