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

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.

, 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
