Origins of AIS (3) - correct answer 1) Standardized system

2) Classify type/severity of injury from MVC

3) Consensus



Injury descriptors are organized _________________________ ? - correct answer Anatomically



Injury severity is ranked relative to its importance to _______________? - correct answer The whole
body



AIS reflects severity of single injuries and are unaffected by what three things? - correct answer 1) time

2) sequela

3) outcome



What type of scale does AIS use? - correct answer 6 point ordinal scale



Which type of measurement is more variable? Anatomic or Physiologic? - correct answer Physiologic



Is clinical training necessary for collecting injury data? - correct answer NO



AIS is based on what three (3) factors? - correct answer 1) anatomically- based

2) consensus driven

3) global



Severity is NOT contingent upon what two (2) factors? - correct answer 1) Outcome

2) time

,Numerical ranking of severity: 1 - correct answer minor



Numerical ranking of severity: 2 - correct answer moderate



Numerical ranking of severity: 3 - correct answer serious



Numerical ranking of severity: 4 - correct answer severe



Numerical ranking of severity: 5 - correct answer critical



Numerical ranking of severity: 6 - correct answer maximum (currently untreatable)



Is mortality a sole determinant of AIS severity? - correct answer NO



Are all AIS data comparable from year to year? - correct answer NO (updates)



Is "DEATH" part of the severity scale? - correct answer NO



Is a patient who dies automatically assigned the highest AIS severity of 6? - correct answer NO (patients
w/ minor injuries can die)



Does a linear relationship exist between AIS severity codes? - correct answer NO (AIS 4 is more, NOT
twice as severe as AIS 2)



Are all injuries within the same AIS code strictly compatible? - correct answer NO (tibia fx & alveolar
ridge are both AIS - 2, although one may be worse than the other, both are considered 'moderate')



What AIS code is assigned to a patient with inadequate information regarding an injury? - correct answer
9

, How many chapters are in the AIS dictionary? - correct answer 9 (not the same as body regions)



AIS single digit severity codes are based on what type of patient? - correct answer Average



What four (4) things define the "average" patient? - correct answer 1) 25-40 yrs old

2) no pre-existing conditions

3) no tx complications

4) received timely/appropriate care



Approximately how many injury descriptors are included in AIS? - correct answer 2000



What part of the AIS code is considered the "Pre-Dot Code?" - correct answer 6 digits BEFORE the
decimal point (left)



What part of the AIS code is considered the "AIS Severity Number?" - correct answer single digit after
the decimal (right)



(T/F) The 6 digit pre-dot codes are unique and allow for more specificity and accurate coding? - correct
answer TRUE



The first digit in the pre-dot code corresponds to what? - correct answer Body Region



The second digit in the pre-dot code corresponds to what? - correct answer Type of anatomic structure
(skeletal, solid organ)



The third/fourth digits in the pre-dot code correspond to what? - correct answer Specific anatomic
structure (femur)



The fifth/sixth digits in the pre-dot code correspond to what? - correct answer Level of injury within the
specific body region and anatomic structure (NFS, minor, major)
