    Summary

    This study developed an optimization model for hospital evacuation plans in urban emergency medical services (EMS) systems. The model identifies limiting resources and demonstrates how augmenting them improves evacuation efficiency.

    Area of Science:

    • Emergency Medicine
    • Operations Research
    • Public Health Policy

    Background:

    • Effective hospital evacuation planning is critical for urban emergency medical services (EMS) systems during mass casualty incidents.
    • Existing planning methods may not fully account for complex resource constraints and dynamic scenarios.

    Purpose of the Study:

    • To develop optimal hospital evacuation plans using a novel evacuation planning model within a large urban EMS system.
    • To illustrate the utility of a decision support model for enhancing hospital evacuation planning.

    Main Methods:

    • An optimization model was employed to generate detailed evacuation plans.
    • Input parameters included patient demographics, available resources (transport teams, vehicles, receiving hospital beds), and evacuation protocols.

    Main Results:

    • Optimal evacuation plans were generated under varied resource levels and rules.
    • Key metrics such as evacuation duration and resource utilization were calculated.
    • The model identified critical resource limitations and demonstrated performance improvements through strategic resource augmentation.

    Conclusions:

    • The developed optimization model provides a valuable tool for EMS administrators and medical directors.
    • It aids in guiding planning decisions and understanding the impact of resource allocation and rules on hospital evacuations.
