Although the term "golden hour" is a well-known concept among trauma system and emergency medical service providers, the relationship between time and trauma patient outcome and the process of prehospital care for road trauma patients in rural settings are poorly understood. As the underlying basis for triage decision-making, the estimated transport interval to trauma center is usually absent in the existing studies.
In this study, the crash data between 2013 and 2017 were obtained from the Fatality Analysis Reporting System, and the estimated intervals were calculated by using a Geographic Information System software. By comparing the estimated intervals with actual emergency medical services records, the field triage patterns for road patients were investigated at the state and county levels.
With the help of the interval prediction maps, the different triage patterns among counties were identified. Further, the average fatalities per 100,000 population by county from the National Highway Traffic Safety Administration were adopted to clarify the associated outcomes. The linear regression analysis results revealed that, for most states, all intervals except the notification interval had a significant correlation with the mortality. The estimated interval had a more significant relationship with the mortality than the actual transport interval. Practical applications: These findings indicated that adhering to the "golden hour" without regarding the destination may not be helpful for the survival of road trauma patients. The regression analyses and the interval maps can be used to identify patterns of inappropriate destination selection so that prospective decision-making can be improved.
尽管“黄金时间”一词在创伤系统和急诊医疗服务提供者中广为人知,但时间与创伤患者结局之间的关系以及农村地区道路创伤患者的院前护理过程仍知之甚少。由于是分诊决策的基本依据,创伤中心的预估转运时间通常在现有研究中缺失。
本研究从 2013 年至 2017 年期间从死亡分析报告系统中获取了碰撞数据,并使用地理信息系统软件计算了预估间隔。通过将预估间隔与实际紧急医疗服务记录进行比较,在州和县两级调查了道路患者的现场分诊模式。
借助间隔预测图,确定了各县之间不同的分诊模式。此外,还采用了美国国家公路交通安全管理局每 10 万人的平均致死率,以阐明相关结局。线性回归分析结果表明,对于大多数州,除了通知间隔外,所有间隔都与死亡率显著相关。预估间隔与死亡率的相关性大于实际转运间隔。
这些发现表明,不考虑目的地而坚持“黄金时间”可能无助于道路创伤患者的存活。回归分析和间隔图可用于识别不适当目的地选择的模式,从而改善前瞻性决策。
