This page contains information about the NEMSIS Version 3 Dataset.
The revision process of the Version 3 Dataset has been conducted in concert with the acquisition of an American National Standards Institute (ANSI) Approval of the NEMSIS Dataset. ANSI approval requires the use of a Standards Development Organization (SDO) to help harmonize the NEMSIS standard with other national standards in the pre-hospital and emergency department settings. Health Level 7 (HL7) is a recognized health care SDO, and NEMSIS has chosen this organization to accomplish this task.
The Version 3 revision has included input from EMS stakeholders across the nation and include EMS agency users and vendors of software products. Vendors 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. Users and vendors have extensive knowledge of EMS electronic patient care record documentation and data collection. These individuals and organizations have played a key role in the development and finalization of the NEMSIS Version 3 Dataset.
