- Changes to NEMSIS Version 2 & 3 Timelines and Revision Cycles!

NHTSA and the NEMSIS Technical Assistance Center (TAC) appreciate the thoughtful deliberations and recommendations of the NASEMSO Data Managers’ Council and the NASEMSO Board of Directors regarding new timelines and revision cycles for the NEMSIS Version 2 and 3 Standards for local, State and national collection of valuable EMS patient care data.

Recognizing that, for a variety of reasons, states and contracted vendors are at different stages of Version 3 implementation, the following policy decisions have been made:

  1. The NEMSIS TAC will continue to collect NEMSIS Version 2 data from the States until 12/31/2016;
  2. The NEMSIS TAC will continue to collect both NEMSIS Version 3.3.4 and NEMSIS Version 3.4 data from the States until 12/31/2017; however, Version 3.4 will officially become the standard on 1/1/2018;
  3. NHTSA and the NEMSIS TAC have agreed that major revisions to the NEMSIS Standard will occur on a four year cycle. The next major revision could be released March, 2018 and would officially become the standard on 1/1/2019.

Some States may be ready to move forward more quickly - which is highly encouraged!
