ADVANCED AUTOMATIC COLLISION NOTIFICATION (AACN)

AACN technology provides vital data about a vehicle crash that can be used by EMS systems to quickly locate the crash location, send the appropriate resources, improve patient outcomes by transporting to the appropriate facility, and optimize the use of scarce EMS resources.

AACN data from vehicle crashes is being shared now with local Public Safety Answering Points (PSAP’s) and 911 centers by the various Telematics Service Providers (TSP’s) and can provide vital information to improve care for injured victims. AACN data can also be used to predict the likelihood of a serious injury in a crash through the use of an Injury Severity Score (ISS). This information can be used to improve triage decision-making and EMS resource utilization, resulting in shorter times to definitive trauma care. An indication that a crash has an injury severity prediction with a “High” probability of severe injury indicates it has met the threshold established by the National Expert Panel for Field Triage. Your system is probably currently the Field Triage Decision Scheme developed by the National Expert Panel which include use of vehicle telemetry data as one of the steps in determining immediate transport to the closest appropriate trauma center.

Most of the Emergency Medical Dispatch (EMD) protocol software/card vendors have already added the use of AACN telematics data into their dispatch protocols so the ability to use AACN crash data might be just sitting there waiting in your system to be utilized. Additional resources on AACN, the Field Triage Decision Scheme, research reports and examples of the various AACN TSP vendors can be found under the Resources tab.

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), are working together to develop an on-line training program to teach EMS and 911 medical directors and EMS personnel about the science behind AACN, how it can be used to develop injury severity predictions, and how to integrate AACN into local EMS systems.
