Annual Meeting Resources
The NEMSIS v3 Implementation Annual Meetings bring together the many voices of EMS data. This group includes State/Territory Offices of EMS, EMS Software Vendors, NHTSA’s Office of EMS, and other National EMS partners. By facilitating critical conversations and open discussion, this gathering helps to ensure that the collection and utilization of EMS data meets the rapidly evolving needs of EMS service and care.
The 2020 Annual Meeting was held virtually over three days of presentations, dialog, breakout sessions, and discussion. Over 150 key EMS stakeholders participated. Located below are resources and presentations from the Annual Meeting.
Annual NEMSIS v3 Implementation Meeting 2020 Agenda
2020 Implementation Meeting Facilitation Slides – This includes the facilitated discussion slides throughout all three days.
The Evolution of NEMSIS – The opening day presentation by Dr. Jon Krohmer and Mr. Eric Chaney, NHTSA’s Office of EMS, which describes the critical nature of accurate, timely, and actionable National EMS data.
EMS & Federal Regulation: Facilitating Bi-Directional Data Exchange – The presentation provided by Ryan Stark, of Page, Wolfberg & Wirth, concerning HIPAA and pre-hospital data exchange.

Annual Meeting Boot Camp
A Boot Camp is offered in conjunction with the Annual v3 Implementation Meeting. It is designed for new and learning State/Territory EMS Data Managers and EMS Directors. This interactive training creates and develops an increased understanding of and proficiency with the NEMSIS Data Standard, State/Territory specific tools, State/Territory support, and additional resources.
Maintaining the Data Standard
The National EMS data standard is established as the universal standard for the collection, sharing, and assessment of pre-hospital patient encounter documentation throughout the United States and Territories. Regular revisions, updates, and critical patches are necessary to reflect the evolving needs of the broader EMS industry and developing standards for health information exchange.
Data Standard Revision Guide 2020 – Read about the process to maintain and update the data standard.
NEMSIS Versioning Schedule v8 – Review the timeline for version schedule, duration between releases, and version lifespan.
Pertinent Negatives and Not Values – These are the different methods utilized when a data element is not applicable to a specific EMS activation.
Schematron Errors and Warnings – Learn about the distinction between errors (causing record failures) and warnings (impacting data quality).
State Specific Tools
State/Territory EMS Data Managers are offered personal one-on-one training and assistance in developing and supporting EMS data collection. Additional resources include:
NEMSIS TAC Version 3 On-Boarding Process for States and Territories – Dec 2017 – Review the necessary steps for successful web service submission of data to the NEMSIS TAC.
v3 Version Change Checklist for States and Territories – This checklist is for states and territories that have already implemented a version of NEMSIS V3 and need to implement a new version of NEMSIS V3 (for example, states that have implemented NEMSIS v3.4.0 and need to implement NEMSIS v3.5.0).
Understanding NEMSIS v3.5
A revision of the EMS data standard includes support tools and documentation.
Role and Scope of UUID in v3.5.0 – Read about the purpose of Universally Unique Identifiers to track ePCR’s and agency resources over time.
Patient and Incident Disposition in v3.5.0 – Learn about the adjustment of eDisposition.12 from one element to four elements to more accurately describe the EMS activation.
Harmonizing NEMSIS and CARES in v3.5.0 – Learn about the alignment of NEMSIS and CARES elements to strengthen of out-of-hospital cardiac arrest data and reduce documentation redundancy.
Additional information about NEMSIS v3.5 is located here.
2020 NEMSIS Boot Camp – The Annual Boot Camp is designed specifically for State/Territory and National Offices of EMS. The Boot Camp teaches and reviews specific requirements and resources that require access to restricted data. (August 25, 2020)
2020 NEMSIS Annual Meeting – The Annual NEMSIS v3 Implementation Meeting brings together State/Territory Offices of EMS, EMS Software Vendors and Developers, and National EMS Partners to discuss and collaborate on issues affecting EMS data. (September 15-17, 2020)
Bidirectional Data Exchange
EMS agencies nationwide still widely report that hospitals and other healthcare providers refuse to share patient information with them, citing Health Insurance Portability and Accountability Act (HIPAA) concerns. Misconceptions about HIPAA create artificial barriers to legitimate, approved bidirectional data exchange between EMS and other providers. As a result, many healthcare systems are missing a critical opportunity to improve patient outcomes and advance evidence-based practices in prehospital care.
To conclusively answer this question, the NEMSIS Technical Assistance Center collaborated with Page, Wolfberg & Wirth to provide an expert legal opinion regarding the bidirectional sharing of patient information between EMS and other healthcare providers.
HIPAA: An Imaginary Barrier to Data Exchange – Please share and use this White Paper as needed.
Legal Opinion: Sharing Patient Data Bidirectionally Under HIPAA – This brief Legal Opinion describes how bidirectional data sharing of patient information is not only allowed but encouraged under HIPAA. It is developed specifically for healthcare administrators, legal counsel, and risk management.
Custom Data Elements
The NEMSIS TAC collaborates with EMS stakeholders to identify needed National Custom Elements to respond to the COVID-19 pandemic. These custom elements are made available to EMS agencies and States in an effort to standardize the documentation and coding of recent travel and potential exposures related to an infectious disease, like COVID-19.
