Emerging communication technologies in emergency medical services.

Advances in communication technologies are changing the face of emergency medical services (EMS). Two communication technologies in particular--cellular-enhanced 9-1-1 service and automatic crash notification (ACN)--will have a considerable impact on EMS. Although enhanced 9-1-1 service from land-line phones is now available in nearly every EMS system across the country, enhanced 9-1-1 service from cell phones currently does not exist. With more and more emergency calls made from cell phones, the implementation of this service is a clear priority. Automatic crash notification, a quickly emerging technology, can potentially provide EMS systems with invaluable data within seconds of when a collision occurs. However, many issues with regard to ACN systems need to be addressed, including liability concerns, access to ACN data, ability of drivers to understand the ACN system, and ACN system architecture. The potential interfaces between ACN systems and EMS systems create significant opportunities to enhance EMS resource management and care of patients involved in motor vehicle crashes. With both cellular-enhanced 9-1-1 and ACN in their infancy, EMS physicians and administrators have a valuable opportunity to provide leadership in the development of these services.
