摘要

目的：本研究旨在审查考虑封闭道路的紧急运输时间，以提出更有效的运输路线，以提高札幌地震灾害期间重伤人员的救生率。札幌是北海道的首府，截至2020年，人口约为197万。方法：利用可公开获得的数据和地理信息系统（GIS）创建运输路线，随后计算札幌的紧急运输时间。封闭道路定义为“高液化潜力地区”和“房屋总毁坏率≥20%地区”的道路。结果：封闭道路集中在城市东北部，紧急运输时间延长，延误时间长达101分钟。其他地区没有出现明显延误。结论：道路封闭地区应急运输时间延长。分流站和半封闭道路也会影响紧急运输时间。为了最大限度地减少紧急运输时间，有必要考虑让护士和医生乘坐救护车对病人进行分类，并与城外的救灾基地医院协调运送重伤员。

Comparison of Emergency Transport Times Affected by Road Closures Under Normal Conditions and During an Earthquake Disaster.

Objectives: This study aimed to examine emergency transport times considering closed roads to propose more efficient transport routes to improve the life-saving rate for seriously injured people in Sapporo during an earthquake disaster. Sapporo is the capital of Hokkaido and has a population of approximately 1.97 million as of 2020.

Methods: Transport routes were created using publicly available data and a geographic information system (GIS), and the emergency transport times in Sapporo were subsequently calculated. Closed roads were defined as roads in "areas with high liquefaction potential" and "areas with a total house destruction rate ≥20%."

Results: Closed roads were concentrated in the northeastern part of the city, as were extended emergency transport times, with delays of up to 101 min. Other areas did not experience significant delays.

Conclusions: The emergency transport time was prolonged in areas with closed roads. Triage posts and semi-closed roads were also suggested to affect emergency transport times. To minimize emergency transport times, it is necessary to consider having nurses and doctors ride in ambulances to triage patients, and to coordinate with disaster base hospitals outside of the city to transport seriously injured people.

期刊介绍： Disaster Medicine and Public Health Preparedness is the first comprehensive and authoritative journal emphasizing public health preparedness and disaster response for all health care and public health professionals globally. The journal seeks to translate science into practice and integrate medical and public health perspectives. With the events of September 11, the subsequent anthrax attacks, the tsunami in Indonesia, hurricane Katrina, SARS and the H1N1 Influenza Pandemic, all health care and public health professionals must be prepared to respond to emergency situations. In support of these pressing public health needs, Disaster Medicine and Public Health Preparedness is committed to the medical and public health communities who are the stewards of the health and security of citizens worldwide.
