GIS and Trauma Center Siting
Track: Health and Human Services
Author(s): Marlen Kokaz, Megan Heckert, Jianguo Li, Charles Branas

The difference between life and death for severely injured people depends upon the amount of time it takes to get them to a trauma center hospital. The Trauma Resource Allocation Model for Ambulances and Hospitals (TRAMAH) is a mathematical model that determines population and land area access to existing trauma centers based on their geographic relationship to ambulances and helicopters and then simulates the location of new or planned trauma centers and related resources in order to maximize patient access. Access is calculated using data from the American Trauma Society, the American Hospital Association, the Association of Air Medical Services, and the US Census Bureau. In Phase 1 of the project, the model is being made available on an interactive Web-based mapping internet site. In Phase 2, the model will be made available as an interactive siting tool targeted at state trauma systems regulatory authorities.
