CAISS EXAM WITH QUESTIONS AND
ANSWERS 2025/26 GRADED A+
This exam is an opportunity to showcase both
theoretical knowledge and practical experience ensuring
alignment with best practices.
Origins of AIS (3) - ANSWER1) 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? - ANSWER1) time
2) sequela
3) outcome
,What type of scale does AIS use? - ANSWER6 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? - ANSWER1)
anatomically- based
2) consensus driven
3) global
Severity is NOT contingent upon what two (2) factors?
- ANSWER1) 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? -
ANSWER1) 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? -
ANSWERTRUE
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)
