Purpose: This study investigated the characteristics and treatment outcomes of patients who visited theemergency department due to intoxication and analyzed the impact of the coronavirus disease 2019(COVID-19) pandemic on their visits.
Methods: A retrospective study was conducted using data from the National Emergency Department In formation System (NEDIS) on patients who visited the emergency department due to intoxication be tween January 2014 and December 2020. In total, 277,791 patients were included in the study, and theirdemographic and clinical data were analyzed. A model was created from 2014 to 2019 and applied to2020 (i.e., during the COVID-19 pandemic) to conduct a time series analysis distinguishing between unex pected accidents and suicide/self-harm among patients who visited the emergency department.
Results: The most common reason for visiting the emergency department was unintentional accidents(48.5%), followed by self-harm/suicide attempts (43.8%). Unexpected accident patients and self-harm/suicide patients showed statistically significant differences in terms of sex, age group, hospitalizationrate, and mortality rate. The time series analysis showed a decrease in patients with unexpected acci dents during the COVID-19 pandemic, but no change in patients with suicide/self-harm.
Conclusion: Depending on the intentionality of the intoxication, significant differences were found in theage group, the substance of intoxication, and the mortality rate. Therefore, future analyses of patientswith intoxication should be stratified according to intentionality. In addition, the time series analysis ofintentional self-harm/suicide did not show a decrease in 2010 in the number of patients, whereas a de crease was found for unintentional accidents.
