Characteristics of Injury Patients in the Emergency Department in Shanghai, China: A Retrospective Observational Study.

ABSTRACT

BACKGROUND This study analyzed the epidemiological characteristics and trends of trauma injuries in Ruijin Hospital North, Shanghai, China, and the feasibility of methods to prevent trauma. MATERIAL AND METHODS In this retrospective cross-sectional study, the electronic databases of Ruijin Hospital North were searched for patients who experienced severe trauma from 2013 to 2016. Characteristics of severe trauma were analyzed, including trauma mechanism, gender, reasons for injury, and injury-associated causes of death. RESULTS Of the 17,093 patients who experienced trauma during the study period, 11,165 (65.3%) were male and 5,928 (34.7%) were female. Analysis by age showed that the highest incidence of traumatic injuries was in subjects aged 25-34 years, whereas analysis by occupation showed the highest incidence of injury in migrant workers without higher education. Classification by Injury Severity Score (ISS) showed that 12,563 (73.5%) subjects had minor injuries, 4,273 (25.0%) had serious injuries, and 256 (1.5%) had severe injuries. In addition, 256 (1.5%) subjects died, with traffic accidents and falling injuries being the main causes of death. The incidence of injury peaked at 9-11 am and 2-4 pm and was significantly higher in autumn and winter than in spring and summer. CONCLUSIONS Most trauma patients were young adults. Injuries due to traffic accidents and falling were the main causes of death, with disregard of driving regulations and other health and safety regulations being the main cause of trauma. Trauma injuries may be prevented by strengthening education and by obeying traffic laws and construction site safety regulations.
