Corrigan (1995) reviewed the literature on alcohol and TBI and found that preinjury alcohol abuse or dependence ranged from 16 to 66%. The most rigorous studies and those conducted in rehabilitation settings produced the highest prevalence rates, between 44 and 66%. People with SCI reported greater than average preinjury alcohol consumption, and 35-49% reported a history of significant alcohol problems (Bombardier & Rimmele, 1998a).Much larger studies of preinjury alcohol problems have been conducted on general trauma patients. Rivara et al. (1993) found that 44% of consecutive trauma admissions scored in the "alcoholic" range on a brief screening measure. In another study, 24% of all admissions met diagnostic criteria for current alcohol dependence (28% for men and 15% for women; Soderstrom et al., 1997).
Alcohol IntoxicationAnother indication of alcohol-related problems among people with TBI or SCI is alcohol intoxication (blood alcohol level greater than 100 mg/dL) at the time of injury. In the seven studies he reviewed, Corrigan (1995) found that rates of alcohol intoxication ranged from 36% to 51% among patients with TBI. Alcohol intoxication rates for SCI reported in the literature are 40% (Heinemann, Schnoll, Brandt, Maltz, & Keen, 1988) and 36% (Kiwerski & Krasuski, 1992). Among general trauma patients, Rivara et al. (1993) found that 47% had a positive blood alcohol level and that 36% were intoxicated.
