Jeong et al modified the revised trauma score in order to better predict mortality in trauma patients. The authors are from Gyeongsang National University in South Korea.
Patient selection: trauma
Outcome: mortality
Parameters:
(1) Glasgow coma score (GCS) from 3 to 15
(2) systolic blood pressure in mm Hg
(3) oxygen saturation in percent (SpO2)

NTS =
= (0.4006 * (GCS)) + (0.2993 * (points for systolic blood pressure)) + (0.8709 * (points for oxygen saturation))
X =
= NTS - 6.5406
probability of survival =
= 1/ (1 + EXP((-1) * X))
triage NTS = T-NTS =
= SUM(points for all 3 parameters)
Interpretation:
• minimum NTS: 1.2019
• maximum NTS: 10.6867.
• minimum T-NTS: 3
• maximum T-NTS: 23
• The higher the T-NTS the better the outcome.
