Abstract

Purpose: In patients with major trauma, mortality varies by age. This study aimed to identify predictors of death according to age. Methods: Data from the Community-Based Severe Trauma Survey in Korea were analyzed using a retrospective case-control design. Factors associated with death were identified by age using independent-samples t-tests, Welch's test, and χ2 tests. Results: There were statistically significant differences in mortality by sex (p=.006), location (p=.029), mechanism of injury (MOI) (p<.001), intention (p<.001), transportation (p<.001), surgery (p<.001), and Injury Severity Score (ISS) (p<.001) in the ≤44 years age group; by location (p<.001), MOI (p=.004), intention (p<.001), transportation (p<.001), surgery (p<.001), and ISS (p<.001) in the 45-54 years age group; by location (p=.040), MOI (p<.001), transportation (p<.001), transfusion (p<.001), surgery (p<.001), and ISS (p<.001) in the 55-64 years age group; by location (p=.015), intention (p<.001), surgery (p<.001), and ISS (p<.001) in the 65-74 years age group; and by location (p=.002), intention (p<.001), transfusion (p=.020), surgery (p<.001), and ISS (p<.001) in the ≥75 years age group. Conclusion: In patients with major trauma, predictors of mortality varied by age.
