The goal of NEMSIS Version 3 is to become a “living” dataset to meet the needs of the ever changing EMS environment. The Version 3 revision has included input from EMS stakeholders across the nation and includes 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.

Agency 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. NEMSIS Version 3 impacts Health Information Exchange, Data Interoperability, Quality Improvement and many other benefits that result from high quality data.

The Version 3 Dataset has also been developed 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 NEMSIS TAC will continue to collect NEMSIS v3.3.4 data until August 2021 and NEMSIS v3.4.0 until January 2024.
