Revised Trauma Score

Revised Trauma Score (RTS)

The RTS considers 3 items:

  • Respiratory rate (/min)
    • 0/min = 0 pts
    • 1-5/min = 1 pt
    • 6-9/min = 2 pts
    • 10-29/min = 4 pts
    • >29/min = 3 pts
  • Systolic blood pressure (mmHg)
    • 0 mmHg = 0 pts
    • 1-49 mmHg = 1 pt
    • 50-75 mmHg = 2 pts
    • 76-89 mmHg = 3 pts
    • >=90 mmHg = 4 pts
  • Glasgow coma scale
    • 3 = 0 pts
    • 4-5 = 1 pt
    • 6-8 = 2 pts
    • 9-12 = 3 pts
    • 13-15 = 4 pts

 

An RTS (the sum of the points) of less than 11 indicates need for transport to a designated trauma center.

 

The RTSc is the RTS coded which weights the individual components.

RTSc = Resp Rate pts x 0.2908 + SBP pts x 0.7326 + GCS points x 0.9368

 

In one survey, RTS corresponded to following rates of mortality:

  • Score:       %Mortality
  • 0                 94%
  • 1-3              67%
  • 4-6              59%
  • 7-9              39%
  • 10-11           27%
  • 12                9%
