Summary
Developing a computer simulation model helps emergency medical services (EMS) managers optimize vehicle base locations. This data-driven approach improves system efficiency and response times for better patient care.
Area of Science:
- Operations Research
- Public Health
- Computer Science
Background:
- Emergency medical services (EMS) system managers struggle with data limitations for optimal expansion and deployment decisions.
- Suboptimal EMS system design results from insufficient usable information, impacting efficiency and patient care.
- A need exists for advanced analytical tools to support strategic EMS planning.
Purpose of the Study:
- To develop and validate a computer simulation model for analyzing EMS system performance.
- To assess the impact of vehicle base locations on key performance indicators within an EMS system.
- To provide data-driven insights for improving EMS operational efficiency and resource allocation.
Main Methods:
- Development of a computer simulation model tailored for EMS operations.
- Analysis of Tucson Fire Department's current EMS system using the simulation model.
- Validation of the simulation model's accuracy and reliability.
- Generation of performance statistics including unit use rates, response times, and critical response time adherence.
Main Results:
- The simulation model provides statistical data on the effects of potential vehicle base locations.
- Performance indicators such as unit use rates, minimum/maximum response times, and proportion of calls within 8 minutes were generated.
- The model was validated and successfully applied to unit redeployment and activation decisions in Tucson, Arizona.
Conclusions:
- Computer simulation offers a viable solution for data-limited EMS decision-making.
- Strategic vehicle base location analysis using simulation can significantly enhance EMS system performance.
- The validated model supports informed decisions for EMS system expansion and unit deployment, leading to improved efficiency and response capabilities.
