In 1970, Texas formed an EMS Personnel Registry. At this time, a list was also approved by the Texas Attorney General requiring qualification for an ambulance permit.
In 1973, the U.S. Congress authorized the Emergency Medical Services Systems Act.
Texas enacted the “EMS Act”, by the 63rd legislature. It established the first advisory council, mandated designation of Trauma Service Areas, stated delivery areas and one Trauma hospital in each, and identified any public or private agencies available for EMS utilization.
