Objective: We aimed to determine the characteristics of in-hospital cardiac arrest (IHCA) patients, as well as the factors influencing survival to discharge and good neurologic outcome.
Method: We examined patients who experienced IHCA from January 1, 2011, to December 31, 2013, in Soonchunhyang University Seoul Hospital. They were divided into a survival group and non-survival group. The patient characteristics, including age, sex, comorbid disease, arrest time, arrest location, witnessed arrest, monitoring, arrest cause, arrest rhythm, and cardiopulmonary resuscitation (CPR) duration, were compared between the groups. Moreover, we assessed the factors associated with survival to discharge and good neurologic outcomes by using multivariate logistic regression analysis.
Results: In total, 453 patients of IHCA were observed. The comorbidities in the survival group included neurologic disease (P < 0.001), arrhythmia (P = 0.001), and myocardial infarction (P = 0.032), pneumonia (P = 0.016). Other characteristics included cardiac arrest at daytime (P = 0.032), cardiogenic arrest cause (P = 0.019), and CPR duration < 15 minutes (P < 0.001). The factors associated with survival to discharge included comorbid neurologic disease (odds ratio [OR], 2.191; P = 0.031), arrhythmia (OR, 3.027; P = 0.009), pneumonia (OR, 3.243; P = 0.002), and CPR duration < 15 minutes (OR, 9.638; P < 0.001). The factors influencing good neurologic outcomes included age < 65 years (OR, 3.158; P = 0.007), comorbid disease as arrhythmia (OR, 4.921; P = 0.001), pneumonia (OR, 4.551; P = 0.001), hypotension (OR, 4.264; P = 0.021), and CPR duration < 15 minutes (OR, 6.652; P = 0.001).
Conclusion: The factors influencing survival to discharge and good neurologic outcomes among IHCA patients included comorbidities, arrest cause, and CPR duration.
