ASCOT use three Anatomic Profile (AP) components (A, B, C). The fourth component is a summary score for all non-serious (AIS 1 or 2) injuries. It was excluded from this model.
Anatomic Profile defined by ICD-9 codes
A : Head, Brain, Spinal
Cord
800, 801, 803 - Skull fx
850 to 854 - Intracranial injury
950 - Injury to optic nerves and pathways
806 - Fx of vertebral column with spinal cord injury
952 - Spinal cord injury without evidence of spinal bone injury
953 - Injury to nerve roots and spinal plexus
B : Thorax, Front of
Neck
807 - Fx of rib(s), sternum, larynx, and trachea
839.61, 839.71 - Dislocation of sternum
860 - Traumatic pneumothorax and hemothorax
861 - Injury to heart / lung
862 - Injury to other intrathoracic organs
901 - Injury to blood vessels of the thorax
874 - Open wound of neck
900 - Injury to blood vessels of head and neck
C : All other serious injury (AIS >= 3)
Patient physiology is recorded
on Emergency Department admission.
Patients with extremely poor or good prognoses were excluded from
logistic function modeling. Table I gives design data set for blunt
and penetrating injury "set-aside".
