Note. The Glasgow Coma Scale is a measure of depth of impaired consciousness following traumatic brain injury or other disorders (Teasdale & Jennett, 1974), scored from 3 to 15, with higher scores indicating greater neurological function; The Injury Severity Score is the sum of the squares of the most severe injury in each of the three most severely injured body regions, scored from 1 (least severe) to 75 (most severe) (Baker & O’Neill, 1976); The Elixhauser score is a count of concurrent pre-existing medical conditions, with higher numbers indicating more conditions present (Elixhauser, Steiner, Harris, & Coffey, 1998); The modified Functional Independence Measure consists of three items: locomotion, feeding, and communication, each rated on a scale of 1 (total dependence) to 4 (total independence), with total scores ranging from 3 to 12 and lower scores indicating greater dependence (Mosenthal et al., 2004).
