BACKGROUND The TIP (Traumatic Injury Prevention) Project evaluated the impact on post-injury drug use of two brief motivational interventions compared to brief advice (BA) among injured patients who use drugs. METHOD Three-group, single blind, randomized controlled trial in a Level 1Trauma Center enrolled 395 admitted patients with drug positive toxicology screen or verbal report of drug use in the previous 30 days. 34% were Hispanic, 45% non-Hispanic White, 16% non-Hispanic Black. 88% smoked marijuana, 28% used cocaine and 11% prescription opioids. Brief Advice (BA) provided advice to abstain from drugs, educational materials and referral to community resources. Brief Motivational Intervention (BMI) additionally included a 30-45 minute session, with assessment feedback, based on motivational interviewing. BMI + B included a telephone booster 4-weeks post-intervention. Drug use as measured by percent days abstinent and total abstinence, derived from the Timeline Follow back was the primary outcome. RESULTS A significant reduction from baseline was observed at 3, 6, and 12 months in the primary outcomes of any drug use (excluding alcohol); cannabis and cocaine, the most frequently used drugs, were analyzed individually. There were no between group differences or group X time interactions. Similarly, there were no between groups differences on secondary outcomes including perceived health status, re-injury, arrest, incarceration, alcohol and drug treatment, employment, AA attendance, homelessness, physical abuse, and problems associated with alcohol and drug use. CONCLUSIONS The study does not support use of these enhanced motivational interventions over brief advice for trauma patients with a positive screen for drug use.

在城市一级创伤中心进行筛查和简短干预以减少伤害和物质滥用的随机试验。

背景技术TIP（创伤预防）项目评估了两种简短的动机干预措施与使用药物的受伤患者的简短建议（BA）相比，对受伤后药物使用的影响。方法在1级创伤中心进行的三组单盲，随机对照试验招募了395名在过去30天内接受过药物阳性毒理学筛查或口头报告有药物使用情况的入院患者。西班牙裔占34％，非西班牙裔白人占45％，非西班牙裔黑人占16％。88％的烟熏大麻，28％的可卡因和11％的处方阿片类药物。简要建议（BA）提供了戒毒，戒毒和转介社区资源的建议。简短的动机干预（BMI）还包括30-45分钟的课程，并根据动机面试提供评估反馈。干预后4周，BMI + B包括电话助推器。主要的结果是根据时间轴追踪追踪得出的戒断日数和总戒断日数来衡量的药物使用情况。结果在使用任何药物（不包括酒精）的主要结局中，在第3、6和12个月观察到与基线相比都有显着降低；大麻和可卡因是最常用的药物，分别进行了分析。组间差异或X组时间之间没有交互作用。同样，两组之间在次要结局方面也没有差异，包括感知的健康状况，再伤害，逮捕，监禁，饮酒和药物治疗，就业，机管局出勤，无家可归，身体虐待以及与饮酒和吸毒相关的问题。
