Acute Trauma Index (PATH Index) (ATI)

  • D. John Doyle


The Acute Trauma Index is based on patient admission values of systolic blood pressure (P), arterial pH (A), prothrombin time (T), and blood hematocrit (H). All these change soon after trauma and provide a means of patient characterization at the time of hospital admission. A large Acute Trauma Index corresponds to an increased likelihood of patient death.
