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)
Origins of AIS (3) --ANSWER--1) Standardized system
Page 1 of 120
,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
Page 2 of 120
,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)
Page 3 of 120
, 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 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)
