BackgroundAlcohol misuse among youth is a major public health concern and numbers of adolescents admitted to the emergency department for acute alcoholic intoxication in Germany are recently growing. The emergency setting offers an opportunity to reach at-risk alcohol consuming adolescents and provide brief interventions in a potential “teachable moment”. However, studies on brief interventions targeting adolescents in emergency care are scarce and little is known about their effectiveness when delivered immediately following hospitalization for acute alcohol intoxication. In this protocol we present the HaLT-Hamburg trial evaluating a brief motivational intervention for adolescents treated in the emergency department after an episode of acute alcoholic intoxication.MethodsThe trial design is a parallel two-arm cluster randomized-controlled trial with follow-up assessment after 3 and 6 months. N = 312 participants aged 17 years and younger will be recruited Fridays to Sundays in 6 pediatric clinics over a period of 30 months. Intervention condition is a manual-based brief motivational intervention with a telephone booster after 6 weeks and a manual-guided intervention for caregivers which will be compared to treatment as usual. Primary outcomes are reduction in binge drinking episodes, quantity of alcohol use on a typical drinking day and alcohol-related problems. Secondary outcome is further treatment seeking. Linear mixed models adjusted for baseline differences will be conducted according to intention-to-treat (ITT) and completers (per-protocol) principles to examine intervention effects. We also examine quantitative and qualitative process data on feasibility, intervention delivery, implementation and receipt from intervention providers, receivers and regular emergency department staff.DiscussionThe study has a number of strengths. First, a rigorous evaluation of HaLT-Hamburg is timely because variations of the HaLT project are widely used in Germany. Second, prior research has not targeted adolescents in the presumed teachable moment following acute alcohol intoxication. Third, we included a comprehensive process evaluation to raise external validity. Fourth, the study involved important stakeholders from the start to set up organizational structures for implementation and maintaining project impact.Trial registrationCurrent Controlled Trials ISRCTN31234060 (April 30th 2012).

Background: Increasing numbers of youth in need of emergency medical treatment following alcohol intoxication have been a major public health concern in Europe in recent years. Brief interventions (BIs) in the emergency department (ED) could prevent future risky drinking. However, effectiveness and feasibility of this approach are currently unclear. Method: A systematic literature search on controlled trials including participants aged 12-25 years treated in an ED following an alcohol-related event was conducted. Additionally, a grey literature search was conducted to support findings from the systematic review with evidence from practice projects and uncontrolled trials. Data on effectiveness, acceptance, implementation and reach were extracted. Results: Seven randomised controlled trials (RCT), 6 practice projects, 1 non-randomised pilot study and 1 observational study were identified. Six RCTs found reductions of alcohol use for all participants. Four RCTs found effects on alcohol consumption, alcohol-related risk-behaviour or referral to treatment. Participation and referral rates varied strongly, whereas data on acceptance and implementation were rarely assessed. Conclusion: Heterogeneity of study designs and effects limit conclusions on effectiveness of BIs for young ED patients following an alcohol-related event. However, the number of practice projects in Europe indicates a need perceived by practitioners to address this population.

OBJECTIVES The proportion of children and adolescents receiving emergency care for acute alcohol intoxication (AAI) in Germany has sharply increased over the past years. Despite this, no randomized controlled trials (RCTs) have studied guideline- and evidence-based interventions to prevent future alcohol misuse within this population. The objective of our investigation was to evaluate the effectiveness of a brief motivational intervention (b-MI) to reduce drinking and associated problems within pediatric emergency departments (PED) in Hamburg, Germany. METHODS This stratified cluster-RCT compared a widely established but modified targeted b-MI and treatment as usual (TAU) for patients recruited and treated on Fridays, Saturdays, or Sundays from July 2011 to January 2014 for AAI in EDs of six pediatric hospitals in Hamburg, Germany. Patients under the age of 18 years and their caregivers were included in the study. Intervention was delivered by trained hospital-external staff. The intervention group (n = 141) received a single-session b-MI with a telephone booster after 6 weeks and a brief consultation for caregivers. All intervention material was manual-based. The TAU control group (n = 175) received youth-specific written information on alcohol use and contact information for community resources. Primary outcomes were changes in binge drinking frequency, number of alcoholic drinks on a typical occasion, and alcohol-related problems using the brief Rutgers Alcohol Problem Index. Outcomes were measured by research assistants not involved in intervention delivery. Baseline data were collected in person at the PED, and follow-up data were collected via telephone 3 and 6 months after baseline. Secondary outcome was postenrollment health service utilization. Analyses were based on linear mixed models and intent to treat. RESULTS A total of 86.1% (87.5%) of patients in the b-MI group and 82.4% (86.9%) in the TAU group provided valid outcome data after 3 (6) months, respectively. The differences between groups for all outcomes were statistically nonsignificant at both follow-ups (p > 0.05). After 3 months the mean change in binge drinking frequency was -1.36 (95% confidence interval [CI] = -1.81 to -0.91), a reduction of 62.1% in the b-MI group, and -1.29 (95% CI = -1.77 to -0.95), a reduction of 49.0% in the TAU group. The mean change in number of alcoholic drinks on a typical occasion was -2.24 (95% CI = -3.18 to -1.29), a reduction of 37.5% in the b-MI group, and -1.34 (95% CI = -2.54 to -0.14), a reduction of 26.4% in the TAU group. The mean change of alcohol-related problems was -6.72 (95% CI = -7.68 to -5.76), a reduction of 60.5% in the b-MI group, and -6.43 (95% CI = -7.37 to -5.49), a reduction of 58.3% in the TAU group. The differences in mean changes between groups were similar after 6 months for all outcomes. CONCLUSION This study provides new information on the effectiveness of b-MIs delivered at discharge of young AAI patients in emergency care. Both trial groups reduced alcohol use and related problems but the b-MI was not associated with significant effects. Although the intervention approach appears feasible, further considerations of improving the outcomes for this relevant target group are required.

INTRODUCTION The CRAFFT questionnaire is a widely utilized measure of problematic alcohol and drug use. The brief screening instrument has been translated into multiple languages, and some studies regarding its psychometric properties have been published. However, investigations on the factorial validity of the CRAFFT in a clinical sample are not available yet and empirical findings on the psychometric properties of the German version of the CRAFFT are very limited. METHODS Data were collected in a German sample of 316 adolescent patients treated in emergency departments following alcohol intoxication. Problematic alcohol use was assessed using the German version of the CRAFFT. Data concerning frequency and quantity of alcohol consumption were collected. A confirmatory factor analysis using the 6 items of the CRAFFT modelled as categorical indicators of a single latent factor using a robust weighted least squares estimator was conducted. We also calculated a reliability coefficient and correlations between the CRAFFT and external criteria of alcohol use. RESULTS The unidimensional model showed excellent global goodness-of-fit (χ(2)=9.76, df=8, χ(2)/df=1.22, RMSEA=0.027, CFI=0.983, TLI=0.976) and satisfying local parameters (standardized factor loadings between 0.37 and 0.69). We observed a poor reliability coefficient of 0.525. A positive association with alcohol use indicated construct validity of the German CRAFFT. DISCUSSION Concerning its factorial and construct validity the German version of the CRAFFT is a promising instrument for measuring problematic alcohol use in clinical adolescent populations, but the reliability has definitely to be investigated again in further studies.

Psychosocial Characteristics of Adolescents Treated for Alcohol Intoxication in Emergency Departments In Germany, every year a substantial number of adolescents is treated in emergency departments for acute alcohol intoxication. Until now, only few studies have been published investigating psychosocial aspects in this group of adolescents. In the present study 316 adolescents were surveyed in the emergency department regarding their problematic use of alcohol and illicit drugs, their patterns of alcohol consumption, their alcohol-related and mental problems. We reported results for the whole sample. Additionally, the sample was divided in two groups based on the result in an established screening instrument for problematic alcohol use (CRAFFT-d). To compare the two groups we conducted unpaired t tests, chi-square tests and logistic regression analyses. Compared to the other group the adolescents exceeding the cut-off value of the CRAFFT-d reported a statistically significant higher past 30-day binge drinking frequency and number of standard-drinks consumed on a typical drinking occasion, more alcohol-related problems, more frequently a problematic use of illicit drugs and more mental problems (regarding antisocial behavior, anger control problems and self-esteem). Antisocial behavior was the most important factor for the affiliation to one of the two groups. The application of the screening instrument for problematic alcohol use (CRAFFT-d) in the emergency department seems to be a promising approach to identify adolescents with a general higher psychosocial burden.
