BACKGROUND
Shorter prehospital time in patients sustaining penetrating trauma has been shown to be associated with improved survival. Literature has also demonstrated that police transport (vs. Emergency Medical Services [EMS]) shortens transport times to a trauma center. The purpose of this study was to determine if ShotSpotter, which triangulates the location of gunshots and alerts police, expedited dispatch and transport of injured victims to the trauma center.
METHODS
All shootings which occurred in Camden, NJ, from 2010 to 2018 were reviewed. Demographic, geographic, response time, transport time, and field intervention data were collected from medical and police records. We compared shootings where the ShotSpotter was activated versus shootings where ShotSpotter was not activated. Incidents, which did not occur in Camden or where complete data were not available, were excluded as were patients not transported by police or EMS.
RESULTS
There were 627 shootings during the study period which met inclusion criteria with 190 (30%) activating the ShotSpotter system. Victims involved in shootings with ShotSpotter activation were more severely injured, more likely to be transported by police, less likely to undergo trauma bay resuscitative measures, and more likely to receive blood products. Mortality, when adjusted for distance, Trauma, and Injury Severity Score, Injury Severity Score, and shock index, was not significantly different between ShotSpotter and non-ShotSpotter incidents. ShotSpotter activation significantly reduced both the response time as well as transport time for both police and EMS (all p < 0.05).
CONCLUSION
The activation of the ShotSpotter technology increased the likelihood of police transport of gunshot victims. Furthermore, the use of this technology resulted in shorter response times as well as transport times for both police and EMS. This technology may be beneficial in enhancing the care of victims of penetrating trauma.

背景
研究表明，穿透性创伤患者的院前时间越短，存活率越高。文献还表明，与紧急医疗服务（EMS）相比，警方运输（police transport）可缩短创伤中心的转运时间。本研究旨在确定枪声定位并向警方发出警报的 ShotSpotter 是否能加快受伤受害者向创伤中心的派遣和转运。
方法
回顾了 2010 年至 2018 年在新泽西州卡姆登发生的所有枪击事件。从医疗和警察记录中收集了人口统计学、地理位置、响应时间、转运时间和现场干预数据。我们比较了激活 ShotSpotter 的枪击事件与未激活 ShotSpotter 的枪击事件。排除了不在卡姆登发生或数据不完整的事件，以及未由警方或 EMS 转运的患者。
结果
研究期间共有 627 起枪击事件符合纳入标准，其中 190 起（30%）激活了 ShotSpotter 系统。激活 ShotSpotter 的枪击事件中的受害者伤势更严重，更有可能由警方转运，不太可能在创伤室进行复苏措施，更有可能接受血液制品。在调整距离、创伤和损伤严重程度评分、损伤严重程度评分和休克指数后，ShotSpotter 和非 ShotSpotter 事件的死亡率无显著差异。ShotSpotter 的激活显著缩短了警察和 EMS 的反应时间和转运时间（均 p < 0.05）。
结论
ShotSpotter 技术的激活增加了警方转运枪击受害者的可能性。此外，使用该技术可缩短警察和 EMS 的反应时间和转运时间。这项技术可能有助于改善穿透性创伤受害者的护理。
