Purpose: The study examined the poisoned patients' characteristics nationwide in Korea by using data from the National Emergency Department Information System (NEDIS). Methods: Among the patients' information sent to NEDIS from January 1, 2013 to December 31, 2015, the included subjects' main diagnosis in ED showed poisoning according to the 7th edition of the Korean Standard Disease Classification (KCD-7). We analyzed the patients' gender, age, initial vital signs, visit time, stay time of staying in ED, results of ED care, main diagnosis in ED, length of hospitalization, and results of hospitalization. Results: A total of 106,779 ED visits were included in the analysis. There were 55,878 males (52.3%), which was more than the number of females. The number of intentional poisoning was 49,805 (59.6%). 75,499 cases (70.8%) were discharged, and 25,858 cases (24.2%) were hospitalized. The numbers of poisoning patients per 1,000 ED visits were 14 in Chungnam and 11.9 in Jeonbuk. The most common cause of poisoning, according to the main diagnosis, was venomous animals. It was the same for hospitalized patients, and pesticide was next. Pesticide was the most common cause of mortality in ED (228 cases, 46.1%) and after hospitalization (584 cases, 54.9%). The incidence of poisoning by age group was frequent for patients in their 30s to 50s, and mortality in ED and post-hospitalization were frequent for patients in their 60s to 80s. Conclusion: This study investigated the characteristics of poisoning patients reported in the past 3 years. Pesticide poisoning had a high mortality rate for patients in ED and in-hospital. For mortality, there was a high proportion of elderly people over 60. Thus, policy and medical measures are needed to reduce this problem. Since it is difficult to identify the poison substance in detail due to nature of this study, it is necessary to build a database and monitoring system for monitoring the causative substance and enacting countermeasures.

AbstractAbstract PDF
Purpose: The Korean government approved selected nonprescription drugs (Over-The-Counter drug; OTC drug) to be distributed in convenience stores from 15. Nov. 2012. This study examined the changes in the incidence and the clinical outcome of acute pharmaceutical drug poisoning after the deregulation of OTC drug sales. Methods: This study analyzed the data of Emergency Department based Injury In-depth Injury Surveillance (EDIIS), Korea Centers for Disease Control and Prevention, from 2011 to 2014. The following items were examined: age, gender, intention, alcohol association, pharmaceutical drugs resulting acute poisoning, the clinical outcomes in emergency department, and the admission rate of intensive care unit (ICU). This is a retrospective cross section observational study. Results: A total of 10,162 patients were subject to pharmaceutical drug poisoning. Acute poisoning by acetaminophen and other drugs were 1,015 (10.0%) and 9,147 (90.0%) patients, respectively. After the deregulation of OTC drug sales, acute poisoning by other drugs increased from 4,385 to 4,762 patients but acute poisoning by acetaminophen decreased from 538 to 477 patients (p<0.05). The rate of admission of acetaminophen poisoning increased from 36.1% (194/538) to 46.8% (223/477). The admission rate to the ICU by acetaminophen poisoning increased from 4.6% (25/538) to 11.3% (54/477) after the deregulation of OTC drug sales (p<0.05). Conclusion: Since the deregulation of OTC drugs sales, pharmaceutical drug poisoning has increased but acetaminophen poisoning has decreased. The rate of hospitalization and ICU admission by pharmaceutical drug poisoning with or without acetaminophen has also increased.

AbstractAbstract PDF
Purpose: The purpose of this study was to investigate the epidemiologic characteristics of patients who visited emergency departments (EDs) after intentional poisoning in Korea. Methods: This study retrospectively analyzed the data of of 23 hospitals during a five-year period, between 2011 and 2015. We included patients who inflicted injury to themselves - attempt of suicide - by means of poisoning. Results: A total of 18,121 patients visited an ED after intentional poisoning. Among them, 58.3% were females; however, there were more males among those aged 60 years or older. The mortality rate for males was 8.6%, which was 3.1 times higher than that for females with 2.8%. The most common poison 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 males and females, 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 basic data for establishing policies to reduce and prevent suicide attempts by poisoning.

AbstractAbstract PDF
Purpose: This study reports the clinical features of infant, child, school aged and adolescent patients treated for acute poisoning in nationwide emergency departments (EDs). Methods: We retrospectively analyzed clinical data pertaining to patients under 19 years of age who were treated for acute poisoning in nationwide EDs from 2013 to 2015. The data were collected by the National Emergency Department Information System (NEDIS). All patients were divided into three groups: 'Infant and child group' (0 to 5 years), 'school age group' (6 to 12 years) and 'adolescent group' (13 to 18 years). General characteristics, Korea Standard Classification of Disease $7^{th}$ (KCD-7) codes and results of care were collected. Results: There were 14,500 pediatric poisoning cases during the study period. The distribution of patient age was bimodal with two peaks among infant, child and adolescent group. The proportion of alert mentality at the ED visit of the infant and child group was 99.3%, while that of the adolescent group was 86.4%. The proportion of intentional intoxication was higher in the adolescent group (40.7%) than other age groups. Among children less than 13 years of age, various poisonous substances and therapeutic drugs were common. Conclusion: There were some clinical differences in acute poisoning patients between age groups. It is necessary to establish a preventive plan considering characteristics by age. Since the KCD-7 code has limitations in analyzing the characteristics of poisoning patients, it is necessary to consider the registration system of poisoning patients.
