This study started from the problem that Korean emergency medical service systems, which are for people’s health and medical service, are integrated compared to those in developed countries and there are few local emergency medical service systems based on cooperation among public sectors, private sectors, and NGOs. According to the results, the effectiveness of local emergency medical services was influenced most positively by the participation factor(b: 0.250, β: 0.248), which was followed by the planning factor(b: 0.224, β: 0.218), the integration factor(b: 0.201, β: 0.207), and the cooperation base factor (b: 0.167, β: 0.149). However, the resource factor and the situation factor did not have a significant effect. This result shows that what is most important for strengthening the partnership of local emergency medical services is the participation of a large number of institutions and, moreover, it is necessary to make plans for cooperation among the participant institutions and to integrate for role allocation. For the effective formation of disaster management communities for local emergency medical services in the future, it is most necessary to build trust among institutions. In addition, public and private sectors should exchange substantial personnel and material resources, and make analysis and judgment on disaster and medical situations jointly. Another keen requirement is regular integrated training. Furthermore, it is necessary to organize a consultation body for coordination among institution and to induce the participation of specialists from private sectors.
