基于可达性计算的急救医疗服务选择

科学的可达性计算是合理选择急救医疗服务的重要基础.本文面向急救医疗服务的合理选择需求，首先分析了急救医疗服务可达性的特征，建立了度量模型；然后，基于这一模型，分别研究了实际交通状态下特定医疗服务和多医疗服务竞争时的可达性，据此确定医疗服务的有效服务范围，合理选择医疗服务.传统的医疗服务可达性研究将可达性作为一个静态的固化值，无法满足人们在紧急情况下的精准就医选择需求.本文提出的可达性计算方案综合考虑了交通状态的时段、路段和方向差异，能更准确精细地计算医疗服务的有效服务范围，为人们在紧急情况时的就医选择提供更准确的决策依据.

Selection of Emergency Medical Service Based on Accessibility Calculation

Scientific accessibility calculation is an important basis for the rational selection of emergency medical services. Aiming at the need of reasonable selection for emergency medical services, firstly, the characteristics of accessibility of emergency medical services are analyzed, and the measurement model is established. Then, based on this model, the accessibility of specific medical services and multi-medical services are studied separately to determine the effective service range of medical services, which supports a reasonable choice of medical services. In traditional studies, accessibility is treated as a static solidification value which can’t meet the precise medical choice needs of people in emergencies. The accessibility calculation program proposed in this paper takes the difference of traffic conditions between time periods, road sections and the driving directions into account, so the effective service scope of medical services can be calculated more accurately, and more accurate decision-making can be made by people to choose medical treatment in emergencies.
