Chicago's CeaseFire program is an evidence-based public health approach to preventing gun violence. Baltimore is one of many US cities attempting to replicate the program. We compared changes in the number of homicide and nonfatal shooting incidents per month in four intervention neighborhoods with changes in high-crime comparison areas (police posts) without the intervention, while controlling for several measures of police activity and baseline levels of homicide and nonfatal shootings. In South Baltimore there were large program-related reductions in homicide and nonfatal shooting incidents. Among three East Baltimore program sites, the program was associated with a reduction of homicides in one area, a reduction in nonfatal shootings in another area, and a simultaneous increase in homicides and decrease in nonfatal shootings in another area. In some instances, program effects extended to neighborhoods bordering the intervention areas. Program-related reductions in homicides appear to be linked with conflict mediations conducted by program outreach workers.
芝加哥的“停火”项目是一种基于证据的公共卫生方法，旨在预防枪支暴力。巴尔的摩是众多试图复制该项目的美国城市之一。我们比较了四个干预社区与没有干预的高犯罪率比较区（警察局）每月的凶杀案和非致命枪击事件数量的变化，同时控制了几项警察活动措施和凶杀案和非致命枪击事件的基线水平。在南巴尔的摩，与项目相关的凶杀案和非致命枪击事件大量减少。在巴尔的摩东部的三个项目地点中，该项目与一个地区的凶杀案减少、另一个地区的非致命枪击案减少以及另一个地区的凶杀案增加和非致命枪击案减少有关。在某些情况下，项目的影响延伸到了干预区的周边社区。与项目相关的凶杀案减少似乎与项目外展工作人员进行的冲突调解有关。
