Factors Influencing Health-related Quality of Life in Adults with Accident or Poisoning Related Treatment Experience in The Past Year: Analysis of the 2023 Korea National Health and Nutrition Examination Survey

Purpose: This study primarily aimed to identify the factors influencing health-related quality of life (HRQoL) in adults with accident- or poisoning-related treatment experience in the past year. Methods: This study employed a cross-sectional descriptive design. The participants were 354 adults who had received medical treatment for accidents or poisoning within the past year. The analysis was based on data obtained from the 2023 Korea National Health and Nutrition Examination Survey. Complex-sample descriptive statistics and inferential tests, including frequencies, <i>x</i><sup>2</sup> tests, complex-sample t-tests, and multiple regression, were conducted using SPSS 29.0. Results: The significant predictors of HRQoL encompassed employment status, age, subjective health perception, activity limitation, high-sensitivity C-reactive protein, perceived stress, and anxiety, with the regression model explaining 41.8% of the variance. Conclusion: The HRQoL of adults who have received treatment for accidents or poisoning is determined by multiple dimensions, including their perceived health, functional limitation level, inflammation, stress, and anxiety, rather than merely by the existence of injury. Therefore, integrated nursing strategies that combine physiological surveillance, early evaluation of psychological status, and tailored interventions centered on functional recovery are required for improving HRQoL in this group.
