Despite nation-wide decreases in crime, urban gun violence remains a serious and pressing issue in many cities. Victim survival in these incidents is often contingent on the speed and quality of care provided. Increasingly, new research has identified the role that specialized trauma care plays in victim survival from firearm-related injuries. Using nearly four years of data on shooting victimizations in Philadelphia we test whether distance to the nearest level 1 trauma center is associated with victim survival. We employ different distance measures based on straight-line Euclidian distance, street network distances, and drive-time estimates—comparing the predictive accuracy of each. Our results find that victims who are shot farther from trauma centers have an increased likelihood of death, and drive time distances provide the most accurate predictions. We discuss the practical implications of this research as it applies to urban public health.

尽管全国范围内的犯罪率有所下降，但城市枪支暴力在许多城市仍然是一个严重而紧迫的问题。这些事件中的受害者存活率通常取决于所提供护理的速度和质量。越来越多的新研究确定了专门的创伤护理在枪支相关伤害的受害者生存中所起的作用。使用近四年的费城枪击受害数据，我们测试到最近的 1 级创伤中心的距离是否与受害者的生存有关。我们采用基于直线欧几里得距离、街道网络距离和行驶时间估计的不同距离度量——比较每个度量的预测准确性。我们的结果发现，在远离创伤中心的地方被枪杀的受害者死亡的可能性增加，和行驶时间距离提供最准确的预测。我们讨论了这项研究适用于城市公共卫生的实际意义。
