Gunshot wounds (GSWs) remain a significant source of mortality in the United States. Timely delivery of trauma care is known to be critical for survival. We sought to understand the relationship of predicted transport time and death after GSW. Given large racial disparities in firearm violence, we also sought to understand disparities in transport times and death by victim race, an unstudied phenomenon.
Firearm mortality data were obtained from the Boston Police Department 2005 to 2023. Firearm incidents were mapped using ArcGIS. Predicted transport times for each incident to the closest trauma center were calculated in ArcGIS. Spatial autoregressive models were used to understand the relationship between victim race, transport time to a trauma center, and mortality associated with the shooting incidents.
There were 4,545 shooting victims with 758 deaths. Among those who lived, the median transport time was 9.4 minutes (interquartile range, 5.8-13.8) and 10.5 minutes (interquartile range, 6.4-14.6; p = 0.003) for those who died. In the multivariable logistic regression, increased transport time to the nearest trauma center (odds ratio, 1.024; 95% confidence interval, 1.01-1.04) and age (odds ratio, 1.016; 95% confidence interval, 1.01-1.02) were associated with mortality. There was a modest difference in median transport time to the nearest trauma center by race with non-Hispanic Black at 10.1 minutes, Black Hispanic 9.2 minutes, White Hispanic 8.5 minutes, and non-Hispanic White 8.3 minutes ( p < 0.001).
Our results highlight the relationship of transport time to a trauma center and death after a GSW. Non-White individuals had significantly longer transport times to a trauma center and predicted mortality would have been lower with White victim transport times. These data underscore the importance of timely trauma care for GSW victims and can be used to direct more equitable trauma systems.

枪伤(GSW)在美国仍是导致死亡的一个主要原因。众所周知,及时提供创伤护理对于生存至关重要。我们试图了解 GSW 后预测的转运时间与死亡之间的关系。鉴于枪支暴力在不同种族之间存在巨大差异,我们还试图了解受害者种族在转运时间和死亡方面的差异,这是一个尚未研究的现象。
2005 年至 2023 年,从波士顿警察局获取枪支死亡率数据。使用 ArcGIS 映射枪支事件。使用 ArcGIS 计算每个事件到最近创伤中心的预测转运时间。使用空间自回归模型来理解受害者种族、转运至创伤中心的时间与枪击事件相关的死亡率之间的关系。
共有 4545 名枪击受害者,其中 758 人死亡。在幸存者中,中位数转运时间为 9.4 分钟(四分位距,5.8-13.8),而死亡者为 10.5 分钟(四分位距,6.4-14.6;p=0.003)。在多变量逻辑回归中,到最近创伤中心的转运时间增加(优势比,1.024;95%置信区间,1.01-1.04)和年龄(优势比,1.016;95%置信区间,1.01-1.02)与死亡率相关。不同种族的到最近创伤中心的中位数转运时间存在适度差异,非西班牙裔黑人 10.1 分钟,黑西班牙裔 9.2 分钟,白西班牙裔 8.5 分钟,非西班牙裔白人 8.3 分钟(p<0.001)。
我们的研究结果突出了转运时间与创伤中心及 GSW 后死亡之间的关系。非白人个体到创伤中心的转运时间明显更长,如果白人受害者的转运时间相同,预计死亡率会更低。这些数据强调了及时为 GSW 受害者提供创伤护理的重要性,并可用于指导更公平的创伤系统。
