Asphyxia is assigned to which ISS region? - ANSWER Head and Neck
Drowning is assigned to which ISS region? - ANSWER Chest
Lumbar spine lesions would be assigned to which ISS region? - ANSWER Abdomen
& pelvic contents
Are external injuries coded independent of their body region? - ANSWER YES
Hypothermia, electrical injuries, and whole body injuries are coded to which ISS
region? - ANSWER External
The ISS score ranged from _____ to _____ ? - ANSWER 1 to 75
What are the two ways an ISS of 75 can be achieved? - ANSWER 1) AIS of 5 in
each of three different body regions
2) AIS of 6 in a single body region
Do patients with an AIS 9 achieve an accurate ISS score? - ANSWER NO
Can less than three regions be used to calculate an ISS? - ANSWER YES
Can more than three regions be used to calculate an ISS? - ANSWER NO
, Do all ISS scores have the same mortality rates? - ANSWER NO (depends on body
regions affected)
Assigning injuries to too few body regions results in what? - ANSWER
underestimation of ISS
Assigning injuries to too many body regions results in what? - ANSWER
overestimation of ISS
Are complications or sequela included in the definition of an injury? - ANSWER NO
Define injury? - ANSWER Anatomic lesion resulting from transfer of injury.
List seven (7) examples of sequela that are coded in AIS as injuries? - ANSWER 1)
HTX/PTX
2) retroperitoneal hemorrhage
3) cerebral edema/swelling
4) ischemic brain damage r/t head trauma
5) blood loss
6) asphyxia
