Anatomic or Physiologic? - answer Physiologic 7) Is clinical training necessary for collecting injury data? - answer NO 8) AIS is based on what three (3) factors? - answer 1) anatomically- based 2) consensus driven 3) global 9) Severity is NOT contingent upon what two (2) factors? - answer 1) Outcome 2) time 10) Numerical ranking of severity: 1 - answer minor 11) Numerical ranking of severity: 2 - answer moderate 12) Numerical ranking of severity: 3 - answer serious 13) Numerical ranking of severity: 4 - answer severe 14) Numerical ranking of severity: 5 - answer critical 15) Numerical ranking of severity: 6 - answer maximum (currently untreatable) 16) Is mortality a sole determinant of AIS severity? - answer NO 17) Are all AIS data comparable from year to year? - answer NO (updates) 18) Is "DEATH" part of the severity scale? - answer NO 19) Is a patient who dies automatically assigned the highest AIS severity of 6? - answer NO (patients w/ minor injuries can die) 20) Does a linear relationship exist between AIS severity codes? - answer NO (AIS 4 is more, NOT twice as severe as AIS 2) 21) 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') 22) What AIS code is assigned to a patient with inadequate information regarding an injury? - answer 9 23) AIS single digit severity codes are based on what type of patient? - answer Average 24) 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 25) Approximately how many injury descriptors are included in AIS? - answer 2000 26) What part of the AIS code is considered the "Pre-Dot Code?" - answer 6 digits BEFORE the decimal point (left) 27) What part of the AIS code is considered the "AIS Severity Number?" - answer single digit after the decimal (right) 28) (T/F) The 6 digit pre-dot codes are unique and allow for more specificity and accurate coding? - answer TRUE 29) The first digit in the pre-dot code corresponds to what? - answer Body Region 30) The second digit in the pre-dot code corresponds to what? - answer Type of anatomic structure (skeletal, solid organ) 31) The third/fourth digits in the pre-dot code correspond to what? - answer Specific anatomic structure (femur) 32) 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) 33) Parenthesis in the AIS dictionary indicate what? - answer synonyms or definitions for injury types 34) Brackets in the AIS dictionary indicate what? - answer inclusionary/exclusionary info, OIS Grades 35) Boxed bold type in the AIS dictionary indicates what? - answer directions to help coder choose appropriate code 36) Semicolons in the AIS dictionary indicate what? - answer separate injury descriptors that are comparable in severity 37) Italics in the AIS dictionary indicate what? - answer proper-named injuries/structures, OIS grades 38) Does AIS assess the severity of multiple injuries? - answer NO (single injury severity only) 39) 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. 40) 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 41) Asphyxia is assigned to which ISS region? - answer Head and Neck 42) Drowning is assigned to which ISS region? - answer Chest 43) Lumbar spine lesions would be assigned to which ISS region? - answer Abdomen & pelvic contents 44) Are external injuries coded independent of their body region? - answer YES 45) Hypothermia, electrical injuries, and whole body injuries are coded to which ISS region? - answer External 46) The ISS score ranged from _____ to _____ ? - answer 1 to 75 47) 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 48) Do patients with an AIS 9 achieve an accurate ISS score? - answer NO 49) Can less than three regions be used to calculate an ISS? - answer YES 50) Can more than three regions be used to calculate an ISS? - answer NO 51) Do all ISS scores have the same mortality rates? - answer NO (depends on body regions affected) 52) Assigning injuries to too few body regions results in what? - answer underestimation of ISS 53) Assigning injuries to too many body regions results in what? - answer overestimation of ISS 54) Are complications or sequela included in the definition of an injury? - answer NO 55) Define injury? - answer Anatomic lesion resulting from transfer of injury.
