Scoring systems for ICU and surgical patients:

ISS - RTS - TRISS (Injury Severity Score - Revised Trauma Score - Trauma Injury Severity Score)

Variables	Severity level (help)	Points
Head and neck	Minor (1) Moderate (2) Serious (3) Severe (4) Critical (5) Maximum (6)
Face	Minor (1) Moderate (2) Serious (3) Severe (4) Critical (5) Maximum (6)
Chest	Minor (1) Moderate (2) Serious (3) Severe (4) Critical (5) Maximum (6)
Abdomen, pelvic contents	Minor (1) Moderate (2) Serious (3) Severe (4) Critical (5) Maximum (6)
Extremity, pelvic girdle	Minor (1) Moderate (2) Serious (3) Severe (4) Critical (5) Maximum (6)
External	Minor (1) Moderate (2) Serious (3) Severe (4) Critical (5) Maximum (6)
ISS =
Respiratory rate (per min)	0 1 - 5 6 - 9 10 - 29 > = 30
Systolic blood pressure (mmHg)	0 1 - 49 50 - 75 76 - 89 > = 90
Glasgow coma scale (help)	3 4 - 5 6 - 8 9 - 12 13 - 15
RTS =
Age (Pediatric cases (Ages < 15) use the blunt model for both blunt and penetrating mechanisms of injury.)	Age < 15 years 15 <= Age <55 Age >= 55 years
Predicted death rate (blunt) TRISS =		Predicted death rate (penetrating) TRISS =
ISS = Sum ((three most weighted region injury)2). ISS equals 75 for any patient with an AIS 6 injury.	TRISS (blunt): Logit =-0.4499 + RTS*0.8085 + ISS*-0.0835 + (age.points)*-1.7430 Predicted death rate = 1/(1 + eLogit)	TRISS (penetrating): Logit =-2.5355 + RTS*0.9934 + ISS*-0.0651 + (age.points)*-1.1360 Predicted death rate = 1/(1 + eLogit)
RTS = Sum ((resp.rate.points)*0.2908; (sbp.points)*0.7326; (Glasgow.points)*0.9368)

Definitions

The current definition of ISS as used in the TRISS model incorporates AIS 6 severity - described in the AIS Manual (AIS-90)

Blunt injury : Non-penetrating, but including crush, laceration, amputation and asphyxia.
Penetrating injury : Bullet, knife, or spike.
