Abstract

BACKGROUND

Trauma systems have been shown to reduce death and disability from injury but must be appropriately configured. A systematic approach to trauma system design can help maximize geospatial effectiveness and reassure stakeholders that the best configuration has been chosen.

METHODS

This article describes the GEOS [Geospatial Evaluation of Systems of Trauma Care] methodology, a mathematical modeling of a population-based data set, which aims to derive geospatially optimized trauma system configurations for a geographically defined setting. GEOS considers a region’s spatial injury profile and the available resources and uses a combination of travel time analysis and multiobjective optimization. The methodology is described in general and with regard to its application to our case study of Scotland.

RESULTS

The primary outcome will be trauma system configuration.

CONCLUSION

GEOS will contribute to the design of a trauma system for Scotland. The methodology is flexible and inherently transferable to other settings and could also be used to provide assurance that the configuration of existing trauma systems is fit for purpose.
