Road Safety is a major cause of death around the world and South Africa has one of the highest road fatality rates. Many measures, engineering and medical, are investigated. However, analysis of the accessibility of emergency care facilities is often overlooked. This paper aims to fill the gap between pre-crash engineering solutions and literature on trauma injuries and emergency care procedures. The focus is on the role that accessibility to emergency care facilities in rural areas plays, given that 50% of the world's population lives in rural areas, which are often omitted from international research. The Western Cape (a rural province with low population volumes and high volume roads in South Africa) is analysed as an example of access to trauma care in rural areas.
It is internationally accepted that the time to emergency care facilities influences the survival chances. However, the international literature still debates the exact time period. In this paper, the 'Golden Hour' is used to analyse the accessibility of emergency care facilities in rural areas and establish a geographical analysis method which identifies risk areas. The analysis can be repeated if the international literature debates regarding the exact time period changes.
A Geographical Information System (GIS) tool revealed that 53% of the fatalities in the rural parts of the Western Cape occur outside the Golden Hour. In high risk crash areas, the fatality risk is up to nine times higher than the province's rural average.
People in need of trauma care after a road crash are most likely to survive if they receive definitive care timeously. At the time of the study, the rural areas in the Western Cape had 44 Emergency Medical Services stations and 29 medical facilities that can assist to provide definitive (trauma) care. Further optimisation of the facility locations is recommended and research has begun.More advanced geographical modelling is possible when improved data becomes available on the 'Golden Hour' theory, differential times for varying injury types or travel speeds of ambulances. This, more advanced, modelling can reduce the road crash burden in rural areas around the world further.
道路安全是全球主要的死亡原因之一,南非的道路死亡率位居前列。人们对许多工程和医疗方面的措施进行了研究。然而,应急护理设施可达性的分析常常被忽视。本文旨在填补碰撞前工程解决方案与创伤损伤及急救程序文献之间的空白。鉴于全球50%的人口生活在农村地区,而这些地区在国际研究中常常被忽略,本文重点关注农村地区应急护理设施可达性所起的作用。以西开普省(南非一个人口稀少但道路繁忙的农村省份)为例,分析农村地区创伤护理的可达性。
国际上公认,到达应急护理设施的时间会影响生存几率。然而,国际文献仍在争论确切的时间段。本文采用“黄金一小时”来分析农村地区应急护理设施的可达性,并建立一种识别风险区域的地理分析方法。如果国际文献中关于确切时间段的争论发生变化,该分析可以重复进行。
地理信息系统(GIS)工具显示,西开普省农村地区53%的死亡事故发生在黄金一小时之外。在高风险碰撞区域,死亡风险比该省农村平均水平高出九倍。
道路碰撞后需要创伤护理的人若能及时得到确定性治疗,存活的可能性最大。在研究期间,西开普省农村地区有44个紧急医疗服务站和29个可协助提供确定性(创伤)护理的医疗设施。建议进一步优化设施位置,相关研究已经展开。当有关于“黄金一小时”理论、不同损伤类型的不同时间或救护车行驶速度的更完善数据时,更先进的地理建模将成为可能。这种更先进的建模可以进一步减轻全球农村地区的道路碰撞负担。
