The study for dispatch decision of medical emergency resources with real-time spatial analysis

According to previous research, the most important factor for patient’s survival is based on the emergency treatment in the ambulance and the effective allocation of emergency resource when emergency patients experience out-of-hospital cardiac arrest (OHCA) before arriving the hospital. This study intended to combine the regional information of emergency medical resources and the data base of geographic information for ambulance to assess the best method of medical treatment for OHCA patients, such as the closest medical center, the level of first-aid capabilities, the proper medical department, the information for hospital beds and the special need for medical section, so that EMD can make decision based on these suggestions. For providing the strategy of emergency ambulance, this research proposed the impact of the optimized population, the level of regional development, the allocation of emergency medical resource, the best timing of executing the chain of survival and the advanced cardiac life support, on the survival rate of OHCA patients through big data analysis. Or through increasing the spatial allocation and flexibility of EMT-P, it can reflect the importance of spatial factors in the challenge for the allocation of emergency medical resources. The results of this study can provide the recommendations for the policy of medical resource allocation.
