Trauma is any physical injury that has the potential to cause prolonged disability and death if the appropriate level of care is not administered in a timely fashion. Existing approaches in the literature and by the American College of Surgeons (ACS) to optimize the network of trauma centers are limiting. To address this challenge, we introduce the Trauma Network Design Problem, a bi-objective mathematical model that aims at determining the optimal trauma network by minimizing the weighted sum of mistriages. We use the trauma network data from 2012 for the state of Ohio to illustrate the use of our approach and conduct sensitivity analysis. While substantial improvements in mistriages can be realized through our approach, the solutions are sensitivity of the weights in the objective terms, trauma volume, and threshold values. We also illustrate how our approach can be used to compare suggestions from the ACS’s NBATS tool.
