Trauma System/Injury Prevention Program Home > Pre-Hospital/EMS Pre-Hospital/EMS

The first phase of Indiana’s trauma system activates immediately following an injury — a call is made to the 911 operator, the response is coordinated among various Emergency Medical Services (EMS) ambulances, initial assessments and diagnoses of the patient are made, and the patient is stabilized and quickly but safely transported to a local hospital or trauma center. EMS crews are often the critical link between the injury-producing event and definitive care at a trauma center or local hospital. The first hour post-injury is known as “the Golden Hour,” when critical skilled care must be provided. The Indiana Department of Homeland Security (IDHS) is responsible for oversight of the EMS in Indiana.
