ABSTRACT
PURPOSE: Poisoning is an important cause of death in Korea. We aimed to investigate the epidemiological characteristics and outcomes for in-hospital cardiac arrest (IHCA) in poisoned patients in Korea. METHODS: This is a population-based study, analyzing 576 IHCA patients who were poisoned and registered in the Korean Health Insurance Review and Assessment Service in 2013. The cardiopulmonary resuscitation outcomes, including survival discharge and 30-day survival rate, were analyzed. The main diagnoses were categorized in accordance with the Korean Standard Classification of Diseases version 6. RESULTS: The overall survival discharge and 30-day survival rate were 31.6% and 15.3%, respectively. The most common etiologies of poisoning were pesticides (54.3%), drugs and medications (21.9%), carbon monoxide (8.9%), and unspecified substances (5.4%); the 30-day survival rate for each etiology was 16.6%, 15.2%, 9.8%, and 19.4%, respectively. A geographical analysis showed a high 30-day survival rate in Gwangju (32.0%), Daejeon (25.0%) and Ulsan (25.0%). CONCLUSION: Pesticides poisoning is the most common cause for IHCA patients. The survival rate after IHCA by poisoning was similar in pesticides poisoning than in other toxic etiologies. Therefore, it is crucial to reduce pesticide poisoning and to establish a poisoning information inquiry system.
