OBJECTIVES: This study analyzed the incidence and characteristics of in-hospital cardiac arrest (IHCA) in Korea based on a sample group of patients that is representative of the population. METHODS: The incidence of IHCA in adults was extracted from HIRA-NIS-2009, a sample of all patients using medical services in Korea. IHCA patients were analyzed according to gender, age, type of medical institute, and classification under the 6th revision of the Korean Standard Classification of Diseases (KCD-6). In addition, to assess the differences arising from the size of medical institutes, the IHCA incidence was analyzed in relation to the number of inpatient beds. RESULTS: Based on the sample data, the total incidence of IHCA in Korea was found to be 2.46 per 1,000 admissions (95% confidence interval [CI], 2.37–2.55). A higher incidence was found among men at 3.18 (95% CI, 3.03–3.33), compared to women at 1.84 (95% CI, 1.74–1.94). The incidence of IHCA was also higher in hospitals that had more than 600 inpatients beds at 5.40 (95% CI, 5.16–5.66) in comparison to those that had less than 600 inpatients beds at 4.09 (95% CI, 3.76–4.36) (p < 0.001). By primary disease, the incidence was the highest for infectious diseases. CONCLUSIONS: We demonstrated that the IHCA incidence based on gender, age, diagnostic group, and number of beds could be analyzed using the insurance claim data from a national representative sample.

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.
