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