The Importance of a Preclinical Trial: A Selected Injury Intervention Program for Pediatric Trauma Centers

Underage drinking, brief interventions, and trauma patients: Are they really special?

BACKGROUND

While the relationship between underage drinking and injury has been well established, few studies have examined whether presenting for an acute injury moderates the efficacy of a brief intervention (BI) on alcohol misuse.

METHODS

Patients (aged 14-20 years) in the emergency department screening positive for risky drinking (Alcohol Use Disorders Identification Test-Consumption score) completed a baseline assessment, were randomized to conditions (a standalone computer-delivered BI [n = 277], a therapist-delivered BI [n = 278], or a control condition [n = 281]), and completed a 3-month follow-up. This secondary analysis of Project U-Connect examined regression models (controlling for baseline values) to examine the main effects of injury and the interaction effects of injury by BI condition on alcohol consumption and consequences.

RESULTS

Among 836 youth enrolled in the randomized controlled trial (mean age, 18.6 years; 51.6% were male; 79.4% were white), 303 (36.2%) had a primary complaint of intentional or unintentional injury. At baseline, injured patients were more likely to be male (p < 0.001) and have higher alcohol consumption (p < 0.01), but were less likely to misuse prescription drugs (p = 0.02) than those presenting for medical reasons. Regression models (controlling for baseline values) demonstrated that injury presentation predicted greater alcohol consumption prior to a BI. The computer BI was more effective at reducing alcohol consequences among those presenting with injury than those presenting for other reasons. Injury did not affect the efficacy of the computer BI on alcohol consumption, and injury did not affect the efficacy of the therapist BI on alcohol outcomes.

CONCLUSIONS

A therapist or computer BI reduced alcohol consumption and consequences among risky drinkers regardless of reason for emergency department presentation highlighting the opportunity to reach a broad array of youth. Although the therapist BI was not moderated by injury presentation, the computer BI was particularly effective at reducing alcohol consequences among those presenting with injury at 3-month follow-up.

Prevention of Traumatic Brain Injury in Youth and Adolescents

The goal of this project was to promote bicycle helmet use via an inpatient educational program. We hypothesized that this program would increase bicycle helmet use. One hundred twenty inpatients with history of regular (>1 time per week) bicycle riding (mean age 10.0 ± 3.6 years; 67 males, 53 females; 57 whites, 59 blacks, 4 other) were randomized to treatment (n = 58) or control (n = 62) groups. All participants received a bicycle helmet. At 1 month, 50 (92.6%) of the intervention group and 48 (82.8%) of the control group wore a helmet every bike ride (P < .07). At 3 months, 50 (96.2%) of the intervention group and 44 (80%) of the controls wore a helmet with every bike ride (P < .03). The study proved feasible, requiring trained personnel to deliver the intervention. Providing a helmet without the intervention was effective in 80% to 83% of cases with respect to parental report of helmet wearing compliance.

An analysis of inner-city students' attitudes towards violence before and after participation in the "Cradle to Grave" programme

BACKGROUND

Cradle to Grave (C2G), a hospital-based violence prevention programme, brings inner-city youth into an urban Level I trauma centre to follow the path of an adolescent gunshot victim from trauma bay to morgue. We hypothesised that C2G alters student attitudes towards gun violence.

METHODS

Eighty-eight adolescents were prospectively enrolled. With parental and student consent, students completed the Attitudes Towards Guns and Violence Questionnaire (AGVQ), a previously validated and reliable social science assessment tool. Two weeks later, the students participated in C2G. The survey was re-administered four weeks after C2G participation. AGVQ results are reported both as a total score and as a breakdown of the four component subscales. Higher AGVQ scores indicate proclivity towards violence. ANOVA compared scores with respect to demographics and type of school (public vs. charter).

RESULTS

C2G altered student's attitudes towards guns and violence. Of 43 public school students, total scores decreased following C2G (p=0.02). The greatest attitudinal change occurred in subscale 1, "Aggressive Response to Shame" (p<0.01). C2G failed to produce significant changes AGVQ scores in the 45 students attending a city charter school. The two groups were found to have baseline differences, with public school students showing higher baseline tendencies towards violence.

CONCLUSIONS

Our hospital-based programme is capable of positively impacting adolescents' attitudes towards guns and violence. This effect is most pronounced in subjects who already display increased tendencies towards violence. These results suggest that hospitals offer a unique opportunity to address the public health crisis posed by inner-city firearm violence.
