Abstract
Objectives
We aimed to describe the epidemiological features and to determine the predictors
for survival to discharge of non-traumatic out-of-hospital cardiac arrest (OHCA) in
Korea.
Subjects and methods
A nationwide Utstein style OHCA database (2006–2007) was constructed from ambulance
records and hospital medical record review. Cases were enrolled when they were non-traumatic
OHCA with presumed cardiac aetiology. Using the population census (2005), we calculated
age–gender standardized incidence rates (SIR) and mortality (SMR). We modelled a multivariate
logistic regression analysis to determine the effect of risk factors on hospital outcomes.
Results
The total number of EMS-assessed non-traumatic OHCA patients was 19 045. The SIR was 20.9 (2006) and 22.2 (2007) per 100 000 and survival-to-discharge rate was 2.3% for EMS-assessed non-traumatic OHCA, and
was 3.5% for the resuscitation-attempted group. From a multivariate logistic regression
analysis, witnessed arrest, and shorter basic life support (BLS) and EMS intervals
turned out to be significant predictors of good outcome in the resuscitation-attempted
group.
Conclusion
From a nationwide OHCA cohort, the incidence of EMS-assessed non-traumatic OHCA was
found to be low. Survival-to-discharge rate in the resuscitation-attempted group was
3.5%, which was significantly associated with witnessed arrest, and shorter BLS and
EMS intervals.
