Comparison of Epidemiological Characteristics and Outcomes for the In-hospital Cardiac Arrest between Poisoned Patients in Korea: A Population Study Based on Korean Health Insurance Review and Assessment Service

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.

Comparison of Epidemiological Characteristics and Outcomes for the in-hospital Cardiac Arrest between Nursing Care Hospitals Versus Non-nursing Care Hospitals of Korea: A Population Study Based on Korean Health Insurance Review and Assessment Service

PURPOSE: The aim of this study was to investigate the epidemiological characteristics and outcomes for in-hospital cardiac arrest (IHCA) patients who were 65 years and older between nursing care hospitals versus non-nursing care hospitals in Korea. METHODS: This is a population study enumerating 24,203 IHCA patients registered in Korean Health Insurance Review and Assessment Service in 2013. The Cardiopulmonary resuscitation (CPR) outcomes including survival discharge and 30 day survival rate were analyzed. The main diagnoses of IHCA patients were categorized according to the Korean Standard classification of Disease version 6 (KCD-6). All data of patients who were CPR recipients in nursing care hospitals were compared with those of CPR recipients in non-nursing care hospitals. RESULTS: The overall survival discharge and 30 day survival rate were 29.5% and 28.1%, respectively. However, the survival discharge rate of IHCA patients was significantly low in nursing care hospitals compared to non-nursing care hospitals (20.0% vs. 30.0%, p<0.001). The 30 day survival rate was similarly low in nursing care hospitals (20.1% vs. 28.4%, p<0.001). The most common diagnosis of IHCA patients was respiratory disease in nursing care hospitals and cardiovascular disease in non-nursing care hospitals. The most common respiratory disease leading to IHCA in nursing care hospitals was acute respiratory infections. CONCLUSION: The survival rate after IHCA was lower in nursing care hospitals, and the major diagnosis leading to CPR was acute respiratory infections rather than chronic underlying diseases. Therefore, it is crucial to set higher standards in performing CPR and controlling infections in nursing care hospitals nationwide.
