Objectives: This study aimed to investigate characteristics of injured patients and trends of discharge rate and treatment outcomes of injured patients over 12 years in South Korea.
Methods: A total of 309,462 injured patients identified from the Korean National Hospital Discharge In-depth Survey Data from 2006 to 2017 were included for analyses. The injury discharge rate was assessed by calculating the standardized discharge rate of injured patients by year, and that of treatment outcomes was assessed by calculating the in-hospital mortality rate. For the treatment outcome characteristics, average length of hospitalization and in-hospital mortality rate by comorbid status and severity of injury were analyzed.
Results: The increasing trend of the injury discharge rate was clearly observed in elderly patients aged 65 years or older and female patients. The most frequent mechanism of injury changed from traffic accidents to fall, which is the most frequent mechanism in the elderly. The average length of hospitalization was much higher in elderly patients and patients with comorbidity or severe injury. The in-hospital mortality was highest in elderly patients with severe injuries. The decreasing trend of in-hospital mortality rate was observed except in male patients, and the largest decline was found among patients aged 25-44 years.
Conclusion: To reduce the burden of injury-related medical expenses, promote health, and improve quality of life while reducing the burden of socio-economic losses, our findings suggest that establishing public health policies and interventions, by focusing on vulnerable populations to injuries such as older female patients and patients with comorbidity and severe injury, could be an effective measure.
