Objectives
Severe trauma remains a leading cause of death in the Republic of Korea. In response, regional trauma centers were established in 2012. This study evaluated the impact of direct prehospital transport to trauma centers on in-hospital mortality among patients with severe trauma using the national trauma registry. Methods: This nationwide observational study utilized data from the Korean community-based trauma registry between 2016 and 2020. Patients with an injury severity score >15 who were directly transported from the prehospital setting were included. Variables analyzed encompassed demographics, injury mechanism, transport time, hospital level, and outcomes. The primary outcome was in-hospital mortality. Both logistic regression and decision tree models were employed. Results: A total of 24,567 patients were included. Overall mortality decreased by 5.2% during the study period. Patients transported to level 1 or 2 trauma centers had a lower mortality rate (23.6%) compared to those transported to level 3 or 4 hospitals (28.0%). The proportion of direct transports to high-level centers increased from 46.7% to 64.1% between 2016 and 2020. Despite longer transport times, patients transported to high-level institutions exhibited improved survival, particularly when transport exceeded 30 minutes, suggesting that hospital selection may be more critical than minimizing transport time. Conclusion: Direct transport to high-level trauma centers improves survival among patients with severe trauma, even when transport times are prolonged. These findings support the importance of a well-organized trauma system that emphasizes hospital capability in prehospital triage decisions.

Objectives
Alcohol misuse has been widely studied as a substantial contributor to injured patients' visits to emergency departments. The current research studied differences in alcohol-related injury variables in China and Korea.
Methods
Data were collected from a sample of 4,509 patients (2,862 males and 1,667 females) reporting at emergency departments in China and Korea using the World Health Organization collaborative study on alcohol and injuries protocol.
Results
More injuries were reported by men, young people aged 25–34 years, employed individuals, and persons who had at least a high-school education. The proportion of injury cases among intoxicated patients was 14% for Chinese and 20% for Koreans. The odds of intentional injuries to intoxicated patients increased significantly when the perpetrator had been drinking, especially for severely intoxicated victims in both countries. The odds of injuries for intoxicated persons in both countries were high during sports and leisure activities; odds ratio (OR) = 3.93, 95% confidence interval (CI) = 2.76–5.59 for Chinese and OR = 10.97, 95% CI = 6.06–19.85 for Koreans.
Conclusion
These findings are a contribution to research in the two Asian countries about the effect of intoxication on injuries especially when both victim and perpetrator are intoxicated.
