Purpose: This study investigated the actual incidence of acute poisoning in Korea on a nationwide scale, with the aim of laying the groundwork for future initiatives in prevention, strategic antidote distribution, and the development of effective emergency treatment for acute poisoning.
Methods
The study analyzed data from 3,038 patients who presented to emergency departments with poisoning-related conditions from June 1, 2022 to December 31, 2022 at 10 sites in nine cities across the country. We extracted data on general characteristics of the poisoning cases, including demographic characteristics (age and gender), place of exposure, reason for poisoning, route of exposure, and the substance involved in the poisoning incident. Age-related patterns in reasons for poisoning, medical outcomes, frequent and primary poisoning substances, and deaths were also analyzed.
Results
The population analyzed in our study was predominantly female, with women constituting 54.74% of all cases. Among infants and children, non-intentional poisoning due to general accidents was the most common cause, accounting for 71.43% of cases. Conversely, suicidal poisoning was more prevalent among teenagers and adults over 20. Fifty-two patients died during the study period, with males comprising approximately two-thirds (67.31%) of these fatalities. Pesticides were the most common poisoning substance among those who died, accounting for 55.77% of such cases. Notably, a significant majority of the victims were elderly individuals aged 60 and above.
Conclusion
This study holds substantial significance, since it represents the first comprehensive investigation and analysis of the symptoms, treatment, and causes of death due to poisoning in Korea on a national scale. By substantially expanding the range and types of poisonous substances examined, we were able to more precisely identify the characteristics and clinical patterns of poisoning cases nationwide.

Purpose: The Korea University Anam Hospital Seoul Poison Control Center (SeoulPCC) was established in accordance with Seoul Metropolitan Government Ordinance No. 7524 “Seoul Metropolitan Government Ordinance on the Prevention of Toxic Substances Poisoning and Accident Safety.” Herein, the center’s annual performance in terms of project results and consultation information for 2022 are reported.
Methods
SeoulPCC operates a helpline (Help Call, 1855-2221) that the general public can use from 9:00 AM to 5:00 PM on weekdays, as well as chatting and chatbot counseling through KakaoTalk’s “Seoul Poison Control Center,” and one-on-one online counseling through the website. Additionally, it has constructed a system for communicating with the general public through social media. Poisoning disease information collected from SeoulPCC from January to December 2022 was analyzed according to the number of requests, age of exposure, gender, location, and reason. Requests from the general public were summarized, and a brief image presenting information on poisoning disease-related consultations was produced.
Results
SeoulPCC has a database containing information on 188,065 toxic substances collected by public institutions and provides this information to the general public and medical staff through its website. In 2022, consultations were performed through phone calls and SNS (social networking service) for 577 cases of poison information and first aid treatment due to exposure to toxic substances. There were 1,431 instances of providing poison information services. The annual requests included 512 exposure cases and 65 non-exposure cases. Furthermore, 366 cases were in Seoul, 145 cases were outside of Seoul, and 66 had an unknown location. The exposure cases included 161 requests from the general public and 351 requests from medical staff.
Conclusion
This is the first annual report in Korea to analyze the occurrence of poisoning based on consultations. It is of major significance that this report serves as a starting point for identifying and tracking the aspects and characteristics of poisoning cases in the pre-hospital stage. In the future, poisoning-related disease information provided through consultations and at the emergency room should be linked, and through real-time collection and analysis, this information should be used as basic data for poisoning disease management policies.

Abstract PDF

Purpose: The annual statistics for poisoning are reported based on the data from poison control centers in many advanced countries. In 2016 a study was conducted to analyze the 2016 Korea Poisoning status. This study was conducted to make a better annual report for poisoning statistics in Korea from a 2017-2018 national representative database. Methods: This study was a retrospective analysis of poisoning patients based on the data from an emergency department (ED) based injury in-depth surveillance project by the Korea Centers for Disease Control and Prevention in 2017-2018. Bite or sting injuries were not included. Results: A total of 17714 patients presented to 23 EDs because of poisoning. Adults above 20 years old age accounted for 84.6% of the population, while the proportion of intentional poisoning was 60.8%. The poisoning substance presented in the ED were therapeutic drugs (51.2%), gas (20.3%), pesticides (16.4%), and artificial substances (11.4%). Overall, 35% of patients were admitted for further treatment. The mortality was 2.4% (422 cases), and the most common fatal substances in order were carbon monoxide, other herbicides, and paraquat. Conclusion: This study showed the 2017-2018 status of poisoning in Korea. The prognosis is different from the cause of poisoning and the initial mental state of the patient. Therefore, appropriate methods for preventing poisoning and therapeutic plans in specific situations are needed.

Abstract PDF: Purpose: Some advanced countries have reported annual statistics for poisoning based on data from poison control centers. This study was conducted to propose a baseline format and statistics of poisoning in Korea from a national representative database. Methods: This study was a retrospective analysis of poisoning patients based on data from an emergency department (ED) based injury in-depth surveillance project by the Korea Centers for Disease Control and Prevention in 2016. Bite or sting injuries were not included. Variables related to poisoning were summarized using a similar format as the National Poison Data System in the United States. Results: A total of 7,820 poisoning patients presented to 23 EDs. Adults ${geq}20$ years accounted for 84% of the population, while the proportion of intentional poisoning was 59.4%. The most common poisoning substances were therapeutic drugs (45%), gas (21%), pesticides (15%), and artificial toxic substances (13%). Overall, 34.5% of patients were admitted for further treatment. The mortality was 3.2% (248 cases), and the most common causative substances were carbon monoxide, glyphosate, and paraquat, in order. Conclusion: This study showed the recent status of poisoning in Korea. However, a comprehensive poisoning registry based on poison control centers may be required to provide more accurate national statistics in the future.
