This study evaluates the impact of a civil remedy program (Beat Health) on drug and disorder problems under experimental field trial conditions. Using calls for service data, the authors find statistically significant differences between the control and experimental groups, when drug problem calls prior to the start of the intervention were compared to drug calls during a 12-month follow-up period. The Beat Health sites, especially the residential sites, improved relative to the control sites. By contrast, the control treatment (patrol response) led to significant increases in drug problems, particularly at the commercial properties included in this study. The authors also examined the spatial influences of the Beat Health and patrol responses in catchment areas surrounding each of the 100 study sites. The results show some improvement in the experimental residential sites. The authors found, however, a possible displacement of drug problems in and around both the commercial experimental and control sites. They show that the displacement effect is most notable in the commercial control sites.
本研究在实验性现场试验条件下评估了一项民事补救计划（“打击健康”）对毒品及相关问题的影响。通过使用服务请求数据，作者发现，将干预开始前的毒品问题请求与12个月随访期内的毒品请求进行比较时，对照组和实验组之间存在统计学上的显著差异。“打击健康”计划实施地点，尤其是住宿场所，相对于对照地点有了改善。相比之下，对照处理（巡逻响应）导致毒品问题显著增加，尤其是在本研究纳入的商业场所。作者还研究了“打击健康”计划和巡逻响应在100个研究地点各自周边集水区的空间影响。结果显示，实验性住宿场所有所改善。然而，作者发现，商业实验组和对照组场所及其周边可能存在毒品问题转移现象。他们表明，这种转移效应在商业对照场所最为显著。
