BackgroundIn 2010, the American Heart Association recommended that postcardiac arrest care should be included in the chain of survival to reduce permanent neurological damage, improve quality of life, and reduce health care expenses of postcardiac arrest care.ObjectivesTo investigate post-in-hospital cardiac arrest (IHCA) survival prior to and after modification of the chain of survival in 2010, with subgroup analyses per age and concomitant coronary heart disease (CHD).MethodsWe retrospectively searched the National Health Insurance Research Database for the 2007-2015 period to collect case data coded as "427.41" or "427.5" per International Classification of Disease Clinical Modification, Ninth revision codes and analyzed the data with SPSS v22.0.ResultsThe 1-day survival rate in the 2011-2015 period was 2% higher than that in the 2007-2010 period (odds ratio [OR] 1.02, 95% confidence interval [CI] 1.01-1.04). Moreover, in the 2011-2015 period, the survival-to-discharge rate was increased by 1% in patients under 65 years (OR 1.01, 95% CI 1.00-1.02) and 1% in CHD patients (OR 1.01, 95% CI 1.01-1.02) compared with that in the 2007-2010 period.ConclusionFor patients with IHCA, the overall short-term survival improved significantly after modification of the chain of survival. Younger patients and patients with CHD had better long-term survival.Copyright © 2020 The Author(s). Published by Elsevier Inc. All rights reserved.
