AACN Training Course for EMS and 911 Medical Directors

Car crashing into pole on street at high speed

This online training program seeks to teach EMS and 911 medical directors, and EMS personnel about the science behind Advanced Automatic Collision Notification, how it can be used to develop injury severity predictions, and how to integrate AACN into local EMS systems.


Advanced Automatic Collision Notification (AACN) data provide crucial and time-sensitive information that can improve care for injured crash victims. These data can help predict the likelihood of serious injury in a crash, improve triage decision-making and EMS resource utilization, and reduce response times, resulting in faster and better care for crash victims.

What’s Happening Now

This two-year project culminated in the development of online educational training for EMS and 911 medical directors and other EMS stakeholders about the benefits of using AACN data to assist in improving patient outcomes for victims of motor vehicle crashes. The goal of this project is to foster the adoption and deployment of AACN nationwide.

The training program includes information on the biomechanics of crash injuries and how crash data are used to predict injury severity. After a crash, electronic data transmitted via AACN can be used to inform EMS dispatch and triage decisions.

Who’s Involved

The AACN project is a joint venture managed by the American College of Emergency Physicians (ACEP) and the National Association of EMS Physicians (NAEMSP), with funding from the National Highway Traffic Safety Administration (NHTSA).

Scott Sasser, MD, FACEP, who assisted in the development of Recommendations from the Expert Panel: Advanced Automatic Collision Notification and Triage of the Injured Patient, serves as the principal investigator for the project. Stewart Wang, MD, PhD, FACS, from the University of Michigan, has conducted research on AACN for years, developed a number of related training programs and serves as the lead subject matter expert.
