Computer simulation-based study of emergency medical rescue strategy / 第二军医大学学报

ABSTRACT

Objective To apply computer simulation technology for simulating the emergency medical rescue of different conditions and optimizing the rescue strategy and resource allocation. Methods Firstly, according to the characteristics of the arrival of the wounded and the state of injury, four alternative strategies were formulated and simulated. Secondly, the optimal strategy was determined by waiting time of the wounded and the working intensities of rescue unit. Finally, the reasonable suggestions for the rescue strategy and rescue force allocation were put forward by simulation analysis of the relationship between the arrival rate of wounded and the number of rescue units. Results First-leave-first-served and the select-units strategy could effectively reduce the waiting time of the wounded and the working intensity of the rescue unit. When the arrival rate of class A(B) of the wounded increased, the total number of rescue units increased at the same time under the premise of meeting the requirements of the medical rescue, with the number of A(B) rescue units increasing more rapidly. Conclusion By simulating the emergency medical rescue process using different strategies, the optimal rescue strategy can be determined; the number of the rescue units is closely related to the arrival rate of the wounded; estimating the arrival rate of the wounded and the average treatment time can provide reference for rescue force allocation.
