The Trauma and Injury Severity Score (TRISS) includes:
The Trauma and Injury Severity Score (TRISS) includes:
Show Hint
One physiological score, one anatomical score, and a patient factor that worsens with years.
Updated On: Jun 24, 2026
- GCS + BP + RR
- RTS + ISS + Age
- RTS + ISS + GCS
- RTS + GCS + BP
Show Solution
The Correct Option is B
Solution and Explanation
TRISS exists to give a number for the chance a trauma patient will live. To do that fairly it needs three different angles on the patient. First it needs how sick the body looks right now, which is the Revised Trauma Score (RTS); the RTS is computed from coma score, systolic pressure, and breathing rate, so those vitals are already folded inside it. Second it needs how bad the actual anatomical damage is, which is the Injury Severity Score (ISS) built from the worst-injured body regions. Third it needs age, because an older person is less likely to survive the same injury. Add those together and you get RTS plus ISS plus Age. The distractors that list GCS or BP on their own are double-counting items that already sit inside the RTS, so they are wrong.\[\boxed{\text{RTS + ISS + Age}}\]
