ANSWERS) |ALREADY 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
How many chapters are in the AIS dictionary? - answer-9 (not the same as body regions)
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
Boxed bold type in the AIS dictionary indicates what? - answer-directives to assist coder
in appropriate use of specific description
Semicolons in the AIS dictionary indicate what? - answer-separate injury descriptors
that are comparable in severity
Italics in the AIS dictionary indicate what? - answer-proper-named injuries/structures,
OIS grades
Does AIS assess the severity of multiple injuries? - answer-NO (single injury severity
only)
The injury Severity Score (ISS) is defined as what? - answer-Sum of the squares of
highest AIS in each of 3 most severely injured ISS body regions.
