Abstract

Purpose: The purpose of this study was to investigate the epidemiologic characteristics of patients who visited the emergency department(ED) after intentional poisoning in Korea.
Methods: This study retrospectively analyzed the data of ED based injury in-depth surveillance of 23 hospitals during five years from 2011 to 2015. We included patients whose intent of injury was 'self-harm and suicide' and mechanism of injury was ‘poisoning’.
Results: A total of 18,121 patients visited the ED after intentional poisoning. Among them, female accounted for 58.3%, but males were more frequent in patients aged 60 years or older. The mortality rate for male was 8.6%, 3.1 times higher than for female 2.8%. The most common poisoned material was pesticides (35.4%) in males and sedative-hypnotics (44.0%) in females. The most common causative agent of death was pesticide in both sexes (75.2% and 65.3%, respectively). Since the production of paraquat was discontinued in 2011, the number of deaths from pesticide poisoning has decreased. The mortality rate declined in both male and female from 12.6% and 4.5% in 2011 to 7.1% and 2.1% in 2015, respectively.
Conclusion: In this study, we analyzed the epidemiologic characteristics of intentional poisoning, especially the frequency of suicide attempts by gender and age group, the cause of suicide, and the causative agent. This can be used as a basic data for establishing policies to reduce and prevent suicide attempts by poisoning in the future.
