Pass Solution A Graded
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
