AbstractAbstract PDF
Purpose: Suicide ranks among the top causes of death among youth in South Korea. This study aimed to identify the characteristics of suicidal individuals treated at emergency departments between 2011 and 2020.
Methods
A retrospective analysis was conducted using data from January 2011 to December 2020 in the Injury Surveillance Cohort, a prospective registry. Patients’ sex, age, mortality, methods of self-harm, and previous suicide attempts were analyzed. The methods of self-harm were categorized into falls, asphyxiation, blunt injuries, penetrating injuries, poisoning, and others. Sub-groups with and without poisoning were compared.
Results
The proportion of self-harm/suicide attempts increased from 2.3% (2011) to 5.0% (2020). The mortality rate decreased from 10.8% (2011) to 6.3% (2020). Poisoning was the most common method (61.7%). Mortality rates ranged from 42.0% for asphyxiation to 0.2% for blunt injuries. Individuals in their 20s showed a marked increase in suicide/self-harm attempts, especially in the last three years. A large proportion of decedents in their 70s or older (52.6%) used poisoning as a method of suicide. The percentage of individuals with two or more previous attempts rose from 7.1% (2011) to 19.7% (2020). The death rates by poisoning decreased from 7.7% (2011) to 2.5% (2020).
Conclusion
Our findings underscore the urgent need for targeted interventions and suicide prevention policies. Managing and reducing suicide and self-harm in emergency settings will require a focus on poisoning, the 10–29 age group, and the elderly. This paper will be valuable for future policies aiming to reduce the societal burden of suicide and self-harm.

AbstractAbstract PDFSupplementary Material
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.
