What is NEMSIS? The National Association of State EMS Directors is working with the National Highway Traffic Safety Administration (NHTSA) and the Trauma/EMS Systems program of the Health Resources and Services Administration (HRSA) to develop a national EMS database. The uses of such a database include:

  • Developing nationwide EMS training curricula.
  • Evaluating patient and EMS system outcomes.
  • Facilitating research efforts.
  • Determining national fee schedules and reimbursement rates.
  • Addressing resources for disaster and domestic preparedness.
  • Providing valuable information on other issues or areas of need related to EMS care.

The NEMSIS Project. The NEMSIS grant is an ongoing project with the following tasks:

  • Promote the NHTSA Uniform Pre-Hospital Dataset.
  • Promote the National EMS Information System Dataset.
  • Promote the National EMS Information System Business Implementation Model.
  • Design and implement a Pilot National EMS Database with web reporting capabilities as a proof of concept.
  • Support and promote state EMS data initiatives directed at implementing NEMSIS.

Participating States. 48 States NASEMSD states and 3 territory members have formally agreed to promote and support all EMS data initiatives within their states to conform to the NHTSA Version 2 dataset. These states will call upon vendors of EMS information system software to assist in implementing the National EMS Information System.

Components of NEMSIS

  • The NHTSA Uniform Pre-Hospital EMS Dataset, Version 2.
    • A comprehensive dataset which serves as a reference to local and state EMS systems as they develop and implement EMS data systems.
    • Captures the following components of EMS service and patient care delivery:
      • Dispatch Data
      • Incident Data
      • Patient Data
          - Demographics
          - Medical History
          - Assessment
          - Medical Device Data
          - Treatments/Medications
          - Procedures
          - Disposition
      • Injury/Trauma Data
      • Cardiac Arrest Data
      • Financial Data
      • EMS System Demographic Data
      • EMS Personnel Demographic Data
      • Quality Management Indicators
      • Outcome Indicators
      • Domestic Terrorism Data
      • Linkage Data
  • National EMS Dataset
    • A small subset of the NHTSA Uniform Pre-Hospital dataset consisting of 68 key data elements.
    • This is the minimal dataset each state is recommended to collect and submit.
    • Each state may choose to collect any amount of data between the full NHTSA Uniform Pre-Hospital Dataset and the National EMS Dataset.
    • Used to establish the National EMS Database.
  • National EMS Database
    • The "warehouse" which will store the data collected from each state based on their chosen dataset.
    • Web-based reporting capability to better define and describe EMS systems, personnel, and services across the country.
  • XML standard
    • Allows new and existing EMS datasets to import or export data based on the version 2 NHTSA dataset standards.
  • Business Model
    • Used for the deployment of the National EMS Information System at the local, state, and national levels.
