AbstractAbstract PDF
Purpose: The purpose of this study was to examine the occurrence of toxic exposure cases in Korean emergency centers using a toxic exposure surveillance system-based report form and to provide guidelines for the prevention and treatment of toxic exposures. Methods: We retrospectively reviewed the medical records of toxic exposure patients who had visited emergency centers from January 2009 to December 2009. Epidemiology data points for the toxic exposure cases included age, gender, type of exposure, number and kind of substances involved, reason and route of poison exposure, management of the patients in the emergency departments, and the clinical outcome. Results: A total of 3,501 patients from 12 emergency departments were enrolled in the study. 50.0% of the total exposure patients were male and 63.0% of the total cases were fatal. Acute intoxication occurred in 91.3% of the total patients and suicidal intent was the most common (43.3%) reason for exposure. The most common route of exposure was ingestion (75.9%). Of the total cases, pesticides were involved in 26.3%, sedatives/hypnotics/antipsychotics were involved in 22.0%, and bites and envenomations were involved in 15.7%. Conclusion: We provided a database of patients who were admitted to emergency departments after poisoning incidents. We recommend that toxicology professionals develop a classification scheme for toxicants which is adequate for Korean domestic circumstances and initiate a toxic surveillance system for all types of exposures. With support of a psychiatric surveillance system for suicidal patients and establishment of social mediation for pesticide poisoning, major reductions in poison exposures can be achieved.

AbstractAbstract PDF
Purpose: The Tox-Info system is a poisonous substance information database developed by the Korean National Institute of Food and Drug Safety Evaluation. The aim of this study was to estimate the coverage effectiveness of the Tox-Info system by comparing the toxic substances included in the database with the distribution of the toxic substances implicated in the cases of intoxicated patients presenting to emergency departments. The secondary aim of the study was to propose any additional substances that should be added to the database. Methods: We retrospectively reviewed the medical records of patients suffering with toxic exposure who had visited any of 12 selected emergency departments in Korea from January 2010 to December 2011. The identified toxic substances were classified into groups including prescription drugs, agricultural chemicals, household products, animals or plants, herbal drugs, and others. We calculated the coverage rate of the Tox-Info database relative to the number of intoxication cases and the type of toxic substances involved. Results: A total of 5,840 intoxicated patient records were collected. Their mean age was $46.6{pm}20.5$ years and 56.2% were female. Of the total intoxication cases, 87.8% of the identified toxic substances were included in the Tox-Info database, while only 41.6% of all of the types of identified toxic substances were included. Broken down by category, 122 prescription drugs, 15 agricultural chemicals, 12 household products, 14 animals or plants and 2 herbal drugs involved in poisoning cases were not included in the Tox-info database. Conclusion: This study demonstrated the clinical usefulness of the Tox-Info system. While 87.8% of the substances involved in the cases were included in the Tox-Info database, the database should be continuously updated in order to include even the most uncommon toxic substances.

AbstractAbstract PDF
Purpose: The aim of this study was to investigate toxic exposures in emergency centers with using a toxic exposure surveillance system-based report form as a preliminary study. Methods: We retrospectively reviewed the medical records of toxic exposure patients who visited emergency centers from January to December 2008. Results: 3,157 patients from 11 emergency centers were enrolled. Males were involved in 47.9% of the total cases of exposure and in 60.1% of the cases of fatal exposure. Suicidal intent was the most common (61.0%) reason and most (87.4%) fatal exposures were suicidal. Pesticides were involved in 30.7% of the cases and sedative/hypnotics/antipsychotics were involved in 20.5%. The substances most frequently involved in fatalities were pesticides, and a 48.4% fatality rate was recorded for paraquat exposure. Conclusion: The toxic exposure data showed the preliminary poisoning events in emergency centers. It is recommended that toxicology professionals should develop a toxic surveillance system and serial reporting should be performed.

AbstractAbstract PDF
Purpose: The living standards vary between the urban and rural areas in Korea. This study aims to compare the characteristics of acute poisoning victims in urban and rural areas. Methods: A retrospective study was conducted over a period of 2 years from 2008 to 2009. The study group included adults over 19 year old with acute poisoning and who were later were admitted to the local emergency medical center located in Daegu, Korea. The exclusion criteria were 1) the victims of adverse effects of therapeutic doses of drugs, 2) the victims with chronic exposure and 3) the victims who were missing data in their emergency medical records. We divided the victims into the adult group (19-64 years old) and the old group (over 65 years old). Results: There were 569 acute poisoning victims during the study period, and they constituted 1.11% of the total ED visits (51,199). Four hundred seventy six patients were enrolled in this study. Out of the 359 acute poisoning victims, 252 victims were from urban areas and 107 victims were from rural areas. They showed statistical differences for gender, ED access, transport, toxins and the time to the ED. In the old group, 61 victims out of 117 were from urban areas and the remaining 56 victims were from rural areas. They showed statistical differences for gender, ED access, toxins and transport. Conclusion: Through the clinical comparison between the acute poisoning victims of urban and rural areas, we exposed the clinical differences between the urban and rural areas, and we concluded that prevention and education for acute poisoning should be generated differently between the two groups.
