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 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? - answe
