More and more hospitals are using the Hospital Incident Command System (HICS) for organizational management under emergency conditions. HICS is an incident management system based on principles of the Incident Command System (ICS), which assists hospitals and healthcare organizations in improving their emergency management planning, response, and recovery capabilities for unplanned and planned events. This study aims to explore how Chinese hospitals manage their organizations with HICS in Mass Casualty Incidents (MCI).

To explore the feasibility of HICS in Chinese hospitals under MCI.

A combination of literature analysis and empirical research was used in this study. Through case studies and experience summarization, the necessity and feasibility of the incident command system (ICS) and the emergency medical response system (EMRS) was demonstrated in the early stage of MCI. Based on this, a new "1 SECTION-5 GROUPS-10 TEAMS " model was proposed, and its value of practical application was discussed in MCI.

Multiple resources must be mobilized In MCI, and it is necessary to establish an ICS and an EMRS as soon as possible in the early stages of MCI. The earlier ICS is set up, the more initiative can be taken. The "1 SECTION-5 GROUPS-10 TEAMS" model proposed in this study has a good effect on the practice of drills and rescues, indicating that this model has a certain promotion effect in the hospital's response to MCI.

The "1 SECTION-5 GROUPS-10 TEAMS" model has high feasibility and can be further verified in the subsequent rescue practice.
