TRISS takes into account which of the following?
|A||GCS, RR, Systolic BP|
|B||RS, ICS, Age|
|C||RS, ICS, IRS|
a. The international golden standard for severity scoring & probability of survival (Ps) calculation is the trauma and injury severity score/ TRISS.
b. TRISS is a composite calculator based on anatomical and physiological severity indicators.
c. For TRISS operation , the RTS parameters(RR, BP, GCS) are vected, vectors being deducted by logistic regression analysis on large US trauma databases
d. RTS(vecteD. = 0.9386(GCS CODE. + 0.7326(BP codE.+ 0.2908(RR codE..RTS can thus take on values from 0 to 7.848
e. TRISS is based on a probability distribution: Ps=1/(1+E.^ (-B.
f. The value b is set by the regression equation b= b0 +b1(RTS)+b2( ISS) + b3(AGE..
g. AGE is defined as a dichotomy available: (AGE <55yrs)= 0: ( AGE > 55yrears)= 1.
h. THE value b is set separately for blunt and penetrating injury
