Purpose: The Korea University Anam Hospital Seoul Poison Control Center (Seoul PCC) has provided counseling services and poisoning prevention projects for the public and medical professionals since January 2022. This report summarizes the center’s performance and consultation data for 2023. Methods: The Seoul PCC operates a helpline (1855-2221) on weekdays from 9 AM to 5 PM, along with chat and chatbot services via KakaoTalk, 1:1 online counseling through its website, and public engagement through social media. Data collected from January to December 2023 were analyzed in terms of case frequency, age, gender, location, reason for exposure, and substance type. Consultation requests from the general public were summarized, and information snapshots were utilized to present information on poisoning-related consultations. Results: In 2023, the center handled 1,231 consultations, including 1,193 post-exposure and 38 non-exposure cases. Among post-exposure cases, 724 were from Seoul, 429 were from other areas, and 78 were from unspecified locations. Requests originated from the public (30.1%, n=359) and medical staff (69.9%, n=834). Frequently reported substances included medications (61.4%), common household products (13.5%), other household items (6.3%), synthetic toxicants (5.7%), and food (3.9%). Children under 12 accounted for 159 cases (13.3%), with exposures to common household products (45.9%), medications (27.7%), food (10.7%), and stationery/toys (11.5%). Conclusion From 2022 to 2023, consultations increased by 113.0%, with child exposures rising 82.7%. Medications remained the most common form of exposure across all ages, while common household products were the leading cause among children under 12. Most exposures were unintentional and occurred at home. In addition, most consultations concluded without a visit to a medical institution.

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.

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.

Background: Survival and post-cardiac arrest care vary considerably by hospital, region, and country. In the current study, we aimed to analyze mortality in patients who underwent cardiac arrest by hospital level, and to reveal differences in patient characteristics and hospital factors, including post-cardiac arrest care, hospital costs, and adherence to changes in resuscitation guidelines. Methods: We enrolled adult patients (≥ 20 years) who suffered non-traumatic cardiac arrest from 2006 to 2015. Patient demographics, insurance type, admission route, comorbidities, treatments, and hospital costs were extracted from the National Health Insurance Service database. We categorized patients into tertiary hospital, general hospital, and hospital groups according to the level of the hospital where they were treated. We analyzed the patients' characteristics, hospital factors, and mortalities among the three groups. We also analyzed post-cardiac arrest care before and after the 2010 guideline changes. The primary end-point was 30 days and 1 year mortality rates. Results: The tertiary hospital, general hospital, and hospital groups represented 32.6%, 49.6%, and 17.8% of 337,042 patients, respectively. The tertiary and general hospital groups were younger, had a lower proportion of medical aid coverage, and fewer comorbidities, compared to the hospital group. Post-cardiac arrest care, such as percutaneous coronary intervention, targeted temperature management, and extracorporeal membrane oxygenation, were provided more frequently in the tertiary and general hospital groups. After adjusting for age, sex, insurance type, urbanization level, admission route, comorbidities, defibrillation, resuscitation medications, angiography, and guideline changes, the tertiary and general hospital groups showed lower 1-year mortality (tertiary hospital vs. general hospital vs. hospital, adjusted odds ratios, 0.538 vs. 0.604 vs. 1; P < 0.001). After 2010 guideline changes, a marked decline in atropine use and an increase in post-cardiac arrest care were observed in the tertiary and general hospital groups. Conclusion The tertiary and general hospital groups showed lower 30 days and 1 year mortality rates than the hospital group, after adjusting for patient characteristics and hospital factors. Higher-level hospitals provided more post-cardiac arrest care, which led to high hospital costs, and showed good adherence to the guideline change after 2010.

Purpose: Malnutrition is a common problem in hospitalized patients that can increase the risk of complications, including infections and length of hospitalization. Appropriate nutritional support is important, particularly in pediatric patients, because growth and development are closely related to the nutritional supply. This study examined the status of nutritional support for pediatric patients in general wards to determine if interventions of the pediatric nutrition support team (pNST) contribute to appropriate nutritional support and help improve their nutritional status. Methods: Between July 2016 and June 2017, all pediatric inpatients who received parenteral nutrition support at the Seoul National University Bundang Hospital were recruited and divided into the NST group and non-NST group according to the activities of pNST. The nutritional status was assessed in all subjects, and the calories and proteins delivered through nutritional support in each group were calculated and then compared with the recommended requirements in pediatric patients. Results: The number of patients recruited was 174: 100 (57.5%) in the NST group and 74 (42.5%) in the non-NST group. Significantly more calories and protein were supplied in the NST group than the non-NST group in hospitalized children aged between four and 17 years (P＜0.05). In the non-NST group, the amounts of calories supplied were insufficient compared to the recommended requirements. The proportion of patients supplied with the appropriate number of calories was 60.0% in the NST group and 20.0% in the non-NST group (P＜0.001), and the proportion of cases supplied with the appropriate amount of protein was 87.0% in the NST group and 62.2% in the non-NST group (P＜0.001). Conclusion Interventions of the pediatric nutrition support team contributed to the sufficient supply of calories and protein and the improvement of clinical outcomes in hospitalized children on parenteral nutrition therapy.

Background: Submental intubation is commonly used during general anesthesia for maxillofacial surgeries as it provides a safe unrestricted surgical access compared to tracheostomy. During submental intubation, soft tissues and blood clots can become lodged in the endotracheal tube. To overcome this problem, we used a laparoscopic trocar.Case: A 52-year-old man with maxillofacial injury was scheduled to undergo an open reduction and internal fixation. We performed submental intubation using laparoscopic trocar, which created sufficient space for the insertion of the endotracheal tube. Unlike conventional methods, our method did not require any blunt dissection and caused significantly less soft tissue damage and required significantly less time. Conclusions Submental intubation with laparoscopic trocar is a one-step method and is quick and easy-to-perform technique with less complications.

Background: Postoperative delirium (POD) has an incidence rate of 9% to 41%. It is directly linked to decreasing cognitive function, increasing length of hospitalization and cost, as well as other complications and mortality. We aimed to assess the risk factors for POD among elderly patients by analyzing data from those who underwent spinal surgery. Methods: This study included 446 patients aged 65 years or older who underwent spinal surgery at our institution between March 2013 and May 2018. Data were collected retrospectively from the patients’ electronic medical records, and logistic regression was used to identify the risk factors associated with POD. The diagnosis of POD was based on the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, and was made through consultation with a psychiatrist during postoperative hospitalization and before discharge. Results: Seventy-eight (78/446, 17.4%) patients were diagnosed with POD. The most relevant risk factor for POD was preoperative cognitive dysfunction (odds ratio [OR], 4.37; 95% confidence interval [CI], 1.60 to 11.93; P = 0.004), followed by emergency surgery (OR, 2.70; 95% CI, 1.27 to 5.74; P = 0.01), age (OR, 1.19; 95% CI, 1.13 to 1.26; P < 0.001), and anesthesia time (OR, 1.01; 95% CI 1.00 to 1.01; P = 0.002). Conclusions Preoperative cognitive dysfunction, emergency surgery, age, and anesthesia time were factors that affected POD occurrence after spinal surgery. Patients with such associated factors may be at a higher risk for POD when undergoing spinal surgery, and hence, careful management may be necessary for these patients.
