QUESTIONS AND CORRECT DETAILED
ANSWERS WITH RATIONALES (VERIFIED
ANSWERS) |ALREADY GRADED A+
Which type of measurement is more variable? Anatomic or Physiologic? - ANSWER-Physiologic
Is clinical training necessary for collecting injury data? - 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? - 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-directions to help coder choose
appropriate code
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
three most severely injured ISS body regions.
What are the six body regions used in the ISS? - ANSWER-1) head & neck
2) face
3) chest
4) abdomen & pelvic organs
5) extremities & pelvis
6) external
Asphyxia is assigned to which ISS region? - ANSWER-Head and Neck
Drowning is assigned to which ISS region? - ANSWER-Chest
Lumbar spine lesions would be assigned to which ISS region? - ANSWER-Abdomen & pelvic contents
Are external injuries coded independent of their body region? - ANSWER-YES
Hypothermia, electrical injuries, and whole body injuries are coded to which ISS region? - ANSWER-
External
The ISS score ranged from _____ to _____ ? - ANSWER-1 to 75
What are the two ways an ISS of 75 can be achieved? - ANSWER-1) AIS of 5 in each of three different
body regions
2) AIS of 6 in a single body region
, Do patients with an AIS 9 achieve an accurate ISS score? - ANSWER-NO
Can less than three regions be used to calculate an ISS? - ANSWER-YES
Can more than three regions be used to calculate an ISS? - ANSWER-NO
Do all ISS scores have the same mortality rates? - ANSWER-NO (depends on body regions affected)
Assigning injuries to too few body regions results in what? - ANSWER-underestimation of ISS
Assigning injuries to too many body regions results in what? - ANSWER-overestimation of ISS
Are complications or sequela included in the definition of an injury? - ANSWER-NO
Define injury? - ANSWER-Anatomic lesion resulting from transfer of injury.
List seven (7) examples of sequela that are coded in AIS as injuries? - ANSWER-1) HTX/PTX
2) retroperitoneal hemorrhage
3) cerebral edema/swelling
4) ischemic brain damage r/t head trauma
5) blood loss
6) asphyxia
7) compartment syndrome
Are preliminary (suspected, possible, rule out) dx codeable? - ANSWER-NO
Are all clinical dx alone codeable? - ANSWER-NO (some require radiologic/autopsy findings)
