Purpose: We sought to assess mortality trends in chest-abdominal trauma patients, before and after theimplementation of the Project Supporting Establishment of Trauma Centers (PSETC) in the Republic ofKorea. Methods: Data from the National Health Insurance Service claims database between 2009 to 2017 wereanalyzed. Patients with chest-abdominal trauma were defined as those with relevant main diagnosiscodes and claims for emergency medical management fees. Mortality and cumulative data were analyzedfor each year to compare mortality before and after the establishment of regional trauma centers acrossKorea (2014). Results: In total, 29,127 patients were included in the analysis. While the annual incidence of trauma-related chest-abdominal injuries increased, mortalities decreased. In particular, the trauma incidencerate among patients over 50 years increased during the study period. Mortalities at trauma centers didnot change year by year after the PSETC. Before and after 2014, when trauma centers operated underthe PSETC, mortalities decreased [trauma cases before the PSETC; n = 14,321 (mortality 5.61), after thePSETC; n = 14,806 (mortality 4.96)]. Conclusion: The number of patients treated for chest-abdominal injuries increased from 2009 to 2017 inKorea, whereas mortalities decreased over the same period.
