중증외상 환자의 장애 및 사망 영향 요인: 산업재해와 비산업재해 비교 연구

Purpose: To analyze the factors affecting mortality and disability in workplace trauma patients and provide a basis for improving on-site emergency response and emergency medical systems to reduce industrial accident-related mortality and disability. Methods: This study analyzed out-of-hospital severe trauma patients classified by 119 paramedics (2016–2021) using the KDCA survey data. Occupational characteristics were compared through frequency and descriptive analyses, and factors affecting severe trauma-related mortality and disability were analyzed using a Mixed Logit Model. Results: The average severity score (ISS) of industrial accident patients was three points higher than that of non-industrial accident patients. In addition, the incidence of disability in industrial accident patients was 1.4 times higher than that, and the mortality rate increased by 61.0%. When comparing the mortality rates by medical facility, patients transported to community and regional emergency medical centers had significantly higher mortality rates than those transported to regional trauma centers. Conclusion: Due to the high severity of trauma caused by industrial accidents, an early response is crucial. Therefore, occupational safety and health managers must possess emergency treatment competencies as first responders.
