The accuracy of the CAGE, the Brief Michigan Alcoholism Screening Test, and the Alcohol Use Disorders Identification Test in screening trauma center patients for alcoholism.

OBJECTIVE To evaluate the accuracy of questionnaire screening instruments to identify lifetime alcohol dependence among trauma center patients. METHODS The study was conducted at a Level I trauma center between September 1994 and November 1996. Patients meeting eligibility requirements (> or = 18 years old, admission from injury scene, > or = 2 days of hospitalization, intact cognition) were evaluated for alcohol abuse and dependence. Screening instruments consisted of the CAGE, the Brief Michigan Alcoholism Screening Test, and the Alcohol Use Disorders Identification Test. Screening results were compared with lifetime alcohol dependence diagnoses made using the in-depth Psychoactive Substance Use Disorders section of the Structured Clinical Interview. Accuracy was quantified as sensitivity, specificity, positive/negative predictive values, and receiver operating characteristic curves (used to calculate area under the curve). RESULTS Of the 1,118 patients studied, lifetime alcohol dependence was diagnosed by Structured Clinical Interview in 397 (35.5%), and abuse was diagnosed in 90 (8.1%) others. The CAGE was the best predictor of lifetime alcohol dependence, i.e., had the largest area under the curve (93%) and the highest sensitivity (84%), specificity (90%), positive predictive value (82%), and negative predictive value (91%). Among patients testing positive for alcohol, 63% had a lifetime alcohol dependence diagnosis. CONCLUSION The CAGE is an efficient screening test to detect alcohol dependence in trauma center populations. It should be used in combination with alcohol testing to identify patients at risk of alcohol use problems.

Life-altering outcomes after lower extremity injury sustained in motor vehicle crashes.

BACKGROUND Lower extremity injuries (LEIs) sustained in vehicular crashes result in physical problems and unexpected psychosocial consequences. Their significance is diminished by low Abbreviated Injury Scale scores. METHODS Drivers who sustained LEIs were identified as part of the Crash Injury Research and Engineering Network (CIREN) and interviewed during hospitalization, at 6 months, and at 1 year. All were occupants of newer vehicles with seatbelts and airbags. RESULTS Sixty-five patients were followed for 1 year. Injuries included mild brain injury (43%), ankle/foot fractures (55%), and bilateral injuries (37%). One year post-injury, 46% reported limitations in walking and 22% with ankle/foot fractures were unable to return to work. Depression (39%), cognitive problems (32%), and post-traumatic stress disorder (18%) were significant in the mild brain injury group. CONCLUSIONS Long-lasting physical and psychological burdens may impede recovery and alter the lifestyle of patients with LEI. These issues need to be addressed by trauma center personnel.

Causes and costs of injuries in multiple trauma patients requiring extrication from motor vehicle crashes

Prospective and contemporaneous medical and economic cost studies of 144 victims of motor vehicle crashes admitted to a regional level I trauma center with multiple injuries (ISS > or = 16) revealed 122 non-ejected patients, of whom 102 required extrication (EXTRIC) from the vehicle for physical or medical reasons and 20 who did not (N group). There were no differences in age (EXTRIC, 34 +/- 17 years; N, 41 +/- 24 years), type of crash (Frontal: 57% EXTRIC, 60% N; Lateral: 32% EXTRIC, 35% N) restraint use (35% EXTRIC, 35% N), or mortality (29% EXTRIC, 30% N). However, the estimated maximum speed before the crash was higher in EXTRIC patients (50 +/- 16 mph vs. 46 +/- 18 mph N, p < 0.04), as was the change in velocity (delta V) on impact (EXTRIC 30 +/- 15 mph; N, 24 +/- 8 mph, p < 0.01). Brain injuries (51% EXTRIC vs. 35% N) and lower extremity injuries were more numerous in EXTRIC patients (59% vs. 20% N, p < 0.003) and the number of splenic, lower extremity, and pelvic injuries associated with shock was greater in EXTRIC patients, p < 0.02; as were postinjury complications. As a result, operating room costs from orthopedic and plastic surgery increased professional charges in the EXTRIC group versus the N group (

77,000, respectively. The lower extremity injuries in EXTRIC patients were primarily a result of body part contacts with intrusions (CIs) of the car occupant compartment structures [73% with vs. 24% without (p < 0.0001)]. In lateral MVCs, brain injuries were also more commonly associated with CIs of the side window frame or A pillar (72% CI vs. 25% no CI; p < 0.035); but as a whole in MVCs in which extrication was necessary, lower extremity injuries from instrument panel or toepan CIs appeared more frequent than those resulting from contacts only (p < 0.0001). In EXTRIC patients, 69% of those in shock had CI injuries, and 80% of the deaths in the EXTRIC group were associated with CI injury. These data suggest that measures designed to prevent CIs by strengthening car passenger compartment structures may reduce the incidence of severe brain and lower extremity injuries and may reduce the need for extrication after MVCs.

Population-based study of police-reported sexual assault in Baltimore, Maryland

A structured in-depth interview employing standardized criteria was used to determine the prevalence of lifetime and current alcohol dependence (alcoholism) in unselected consecutive patients admitted to a regional Level I trauma center. Of 629 patients, 157 (25.0%) were current alcoholics at the time of injury. An additional 87 (13.8%) were diagnosed as lifetime non-current alcoholics. There was no significant difference in the rates of current alcohol dependence among patients injured in vehicular crashes (23.5%), other unintentional trauma victims (29.3%), and those injured as a result of violence (24.6%). Of BAC+ (blood alcohol concentration positive) patients, 54.5% were current alcoholics. However, 14.4% of alcohol-negative patients were also diagnosed as alcohol dependent.
