Complete Solutions Graded A+
Origins of AIS (3) - Answer: 1) Standardized system
2) Classify type/severity of injury from MVC
3) Consensus
Injury descriptors are organized _________________________ ? - Answer: Anatomically
Injury severity is ranked relative to its importance to _______________? - Answer: The whole body
AIS reflects severity of single injuries and are unaffected by what three things? - Answer: 1) time
2) sequela
3) outcome
What type of scale does AIS use? - Answer: 6 point ordinal scale
Which type of measurement is more variable? Anatomic or Physiologic? - Answer: Physiologic
Is clinical training necessary for collecting injury data? - Answer: NO
AIS is based on what three (3) factors? - Answer: 1) anatomically- based
2) consensus driven
3) global
Severity is NOT contingent upon what two (2) factors? - Answer: 1) Outcome
2) time
,Numerical ranking of severity: 1 - Answer: minor
Numerical ranking of severity: 2 - Answer: moderate
Numerical ranking of severity: 3 - Answer: serious
Numerical ranking of severity: 4 - Answer: severe
Numerical ranking of severity: 5 - Answer: critical
Numerical ranking of severity: 6 - Answer: maximum (currently untreatable)
Is mortality a sole determinant of AIS severity? - Answer: NO
Are all AIS data comparable from year to year? - Answer: NO (updates)
Is "DEATH" part of the severity scale? - Answer: NO
Is a patient who dies automatically assigned the highest AIS severity of 6? - Answer: NO (patients w/
minor injuries can die)
Does a linear relationship exist between AIS severity codes? - Answer: NO (AIS 4 is more, NOT twice as
severe as AIS 2)
Are all injuries within the same AIS code strictly compatible? - 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? - Answer: 9
AIS single digit severity codes are based on what type of patient? - Answer: Average
, What four (4) things define the "average" patient? - 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? - Answer: 2000
What part of the AIS code is considered the "Pre-Dot Code?" - Answer: 6 digits BEFORE the decimal
point (left)
What part of the AIS code is considered the "AIS Severity Number?" - 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? - Answer:
TRUE
The first digit in the pre-dot code corresponds to what? - Answer: Body Region
The second digit in the pre-dot code corresponds to what? - Answer: Type of anatomic structure
(skeletal, solid organ)
The third/fourth digits in the pre-dot code correspond to what? - Answer: Specific anatomic structure
(femur)
The fifth/sixth digits in the pre-dot code correspond to what? - Answer: Level of injury within the specific
body region and anatomic structure (NFS, minor, major)
Parenthesis in the AIS dictionary indicate what? - Answer: synonyms or definitions for injury types
Brackets in the AIS dictionary indicate what? - Answer: inclusionary/exclusionary info, OIS Grades
