Questions and Answers
Updated (Verified Answers)
1. Origins of AIS (3)
: ANS 1) Standardized system
2) Classify type/severity of injury from MVC
3) Consensus
2. Injury descriptors are organized
ANS Anatomi- cally
3. Injur
y severity is ranked relative to its importance to
ANS -
The whole body
4. AIS reflects severity of single injuries and are unaffected by what
three things
ANS 1) time
2) sequela
3) outcome
,5. What type of scale does AIS use
ANS 6 point ordinal scale
6. Which type of measurement is more variable? Anatomic or Physiologic
ANS -
Physiologic
7. Is clinical training necessary for collecting injury data
ANS NO
8. AIS is based on what three (3) factors
ANS 1) anatomically- based
2) consensus driven
3) global
9. Severity is NOT contingent upon what two (2) factors
ANS 1) Outcome
2) time
10.Numerical ranking of severity
: ANS 1: minor
11.Numerical ranking of severity
: ANS 2: moderate
,12.Numerical ranking of severity
: ANS 3: serious
13.Numerical ranking of severity
: ANS 4: severe
14.Numerical ranking of severity
: ANS 5: critical
15.Numerical ranking of severity
: ANS 6: maximum (currently untreatable)
16.Is mortality a sole determinant of AIS severity
ANS NO
17.Are all AIS data comparable from year to year
ANS NO (updates)
18.Is "DEATH" part of the severity scale
ANS NO
19.Is a patient who dies automatically assigned the highest AIS severity
of 6
ANS NO (patients w/ minor injuries can die)
, 20.Does a linear relationship exist between AIS severity codes
ANS NO (AIS 4 is more, NOT twice as severe as AIS 2)
21.Are all injuries within the same AIS code strictly compatible
ANS NO (tibia fx & alveolar ridge are both AIS - 2, although one may be
worse than the other, both are considered 'moderate')
22.What AIS code is assigned to a patient with inadequate information
regard- ing an injury
ANS 9
