_________________________ ?
Injury severity is ranked The whole body
relative to its importance
to _______________?
AIS reflects severity of single 1) time
injuries and are unaffected by 2) sequela
what three things?
3) outcome
What type of scale does AIS 6 point ordinal scale
use?
Which type of measurement Physiologic
is more variable? Anatomic
or Physiologic?
,Is clinical training NO
necessary for collecting
injury data?
1) anatomically- based
AIS is based on what three
2) consensus driven
(3) factors?
3) global
Severity is NOT contingent 1) Outcome
upon what two (2) factors? 2) time
Numerical ranking of minor
severity: 1
Numerical ranking of moderate
severity: 2
Numerical ranking of serious
severity: 3
Numerical ranking of severe
severity: 4
Numerical ranking of critical
severity: 5
Numerical ranking of maximum (currently untreatable)
severity: 6
Is mortality a sole NO
determinant of AIS severity?
Are all AIS data comparable NO (updates)
from year to year?
Is "DEATH" part of the NO
severity scale?
,Is a patient who dies NO (patients w/ minor injuries can die)
automatically assigned the
highest AIS severity of 6?
NO (AIS 4 is more, NOT twice as severe as AIS 2)
Does a linear relationship
exist between AIS severity
codes?
Are all injuries within the NO (tibia fx & alveolar ridge are both AIS - 2, although one
same AIS code strictly may be worse than the other, both are considered
compatible? 'moderate')
What AIS code is assigned to 9
a patient with inadequate
information regarding an
injury?
AIS single digit severity codes Average
are based on what type of
patient?
What four (4) things define 1) 25-40 yrs old
the "average" patient? 2) no pre-existing conditions
3) no tx complications
4) received timely/appropriate care
Approximately how many 2000
injury descriptors are
included in AIS?
What part of the AIS code is 6 digits BEFORE the decimal point (left)
considered the "Pre-Dot
Code?"
What part of the AIS code is single digit after the decimal (right)
considered the "AIS Severity
Number?"
, (T/F) The 6 digit pre-dot TRUE
codes are unique and allow
for more specificity and
accurate coding?
The first digit in the predot Body Region
code corresponds to what?
The second digit in the pre- Type of anatomic structure (skeletal, solid organ)
dot code corresponds to
what?
The third/fourth digits in Specific anatomic structure (femur)
the pre-dot code
correspond to what?
The fifth/sixth digits in the Level of injury within the specific body region and anatomic
pre-dot code correspond to structure (NFS, minor, major)
what?
Parenthesis in the AIS synonyms or definitions for injury types
dictionary indicate what?
Brackets in the AIS dictionary inclusionary/exclusionary info, OIS Grades
indicate what?
Boxed bold type in the directions to help coder choose appropriate code
AIS dictionary indicates
what?
Semicolons in the AIS separate injury descriptors that are comparable in severity
dictionary indicate what?
Italics in the AIS dictionary proper-named injuries/structures, OIS grades
indicate what?
Does AIS assess the NO (single injury severity only)
severity of multiple
injuries?
The injury Severity Score Sum of the squares of highest AIS in each of three most
(ISS) is defined as what? severely injured ISS body regions.
