CAISS Questions and Answers Graded A Origins of AIS (3) 1) Standardized system 2) Classify type/severity of injury from MVC 3) Consensus Injury descriptors are organized _________________________ ? Anatomically Injury severity is ranked relative to its importance to _______________? The whole body AIS reflects severity of single injuries and are unaffected by what three things? 1) time 2) sequela 3) outcome What type of scale does AIS use? 6 point ordinal scale Which type of measurement is more variable? Anatomic or Physiologic? Physiologic Is clinical training necessary for collecting injury data? NO AIS is based on what three (3) factors? 1) anatomically- based 2) consensus driven 3) global Severity is NOT contingent upon what two (2) factors? 1) Outcome 2) time Numerical ranking of severity: 1 minor Numerical ranking of severity: 2 moderate Numerical ranking of severity: 3 serious Numerical ranking of severity: 4 severe Numerical ranking of severity: 5 critical Numerical ranking of severity: 6 maximum (currently untreatable) Is mortality a sole determinant of AIS severity? NO Are all AIS data comparable from year to year? NO (updates) Is "DEATH" part of the severity scale? NO Is a patient who dies automatically assigned the highest AIS severity of 6? NO (patients w/ minor injuries can die) Does a linear relationship exist between AIS severity codes? NO (AIS 4 is more, NOT twice as severe as AIS 2) Are all injuries within the same AIS code strictly compatible? 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? 9 AIS single digit severity codes are based on what type of patient? Average What four (4) things define the "average" patient? 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? 2000 What part of the AIS code is considered the "Pre-Dot Code?" 6 digits BEFORE the decimal point (left) What part of the AIS code is considered the "AIS Severity Number?" single digit after the decimal (right) (
