SCORING SYSTEMS

TRAUMATIZED CHILDREN

Scoring systems aim to reduce

large amounts of data

to

simple grades or numbers

Aim

Do we need scoring systems ?

- Second peak

- Late

The Abbreviated Injury Score (AIS)

Division of the body into six regions:

1- Thorax 2- Abdomen and viscera

3- Head and Neck 4- Face

5- Bony pelvis and extremities

6- External structures

Scoring for each region injury as:

No injury (0), minor (1), moderate (2), serious (3), severe (4),

critical (5), incompatible with life (6)

The sum of squares from the highest AIS

grades in each of the three most severely

injured areas.

•75 points = worst outcome

•AIS of any region : 6 points = worst outcome

•30-40 points = 50% survival

Injury Severity Score (ISS)(Baker et al 1974)

New Injury Severity Score (NISS)(Osler et al 1997)

• The AIS is the frame.

• Based on the three most severe

injuries regardless the body regions.

• Useful for penetrating injuries.

CRAMS Scale Gormican, (1982).

APACHE II

• A) 12 physiological variables: 60 points

• B) Age:

• 44 yrs = 0 points

• >75 yrs = 6 points

• C) Chronic Health points :

• -Non-oper or emerg. Postop. ….. 5 points

• -Elective postop. ….. 2 points

APS in

APACHE II

(R / 1-R) = -3.517 + (APACHE II x 0.146 + S + D)

R = Risk of hospital death

S = Risk of emergency surgery

D = Risk of specific disease

APACHE II equation :

APACHE III Score

- Variables & weights :

Added weights to APS, Age, and CHE

Refined Glasgow Coma Scale

- Interactions

APACHE III Score

( R / 1-R ) =( APACHE III x 0.053 )+ S+D+L

R = Risk of hospital death

S = Risk of emergency surgery

D = Risk of specific disease

L = Risk of patient location

APACHE III equation :

Pediatric Trauma BIG Score

Borgman MA et al .Pediatrics 2011 ;127 : 892 -7

BIG Score = (BD) + (2.5xINR) + (15 - GCS)

10+(2.5x3.5)+6=26= Predicted mortality : 50%

IRAQ & AFGANESTAN Military study

Key points

• Trauma scoring systems in children canplay a complementary role in decidingpatient outcome.

• Some trauma scoring systems are useful fortriaging of traumatized children and alsofor testing quality assurance of traumacenters or comparing their performance.
