OBJECTIVE: This study aimed to determine additional predictors of cardiopulmonary resuscitation success using a national emergency medical services (EMS) database. METHODS: This retrospective study was conducted by retrieving data from the Information Technology of Emergency Medical Service, a national EMS database. The inclusion criteria were adult patients (18 years old or over) who suffered from out-of-hospital cardiac arrest and received emergency life support. The outcome was a return of spontaneous circulation (ROSC). Predictors for ROSC were determined using multivariate logistic regression analysis. RESULTS: During the study period, 1070 patients met the study criteria, among whom 199 (18.60%) belonged to the ROSC group. Five factors were eligible for multivariate logistic regression analysis for predicting ROSC. Accordingly, only adrenaline administration was independently and negatively associated with ROSC with an adjusted odds ratio of 0.722 (95% confidence interval: 0.522, 0.997) and a Hosmer–Lemeshow Chi-square of 5.84 (P = 0.665). CONCLUSIONS: Adrenaline use may be a poor predictor for ROSC during out-of-hospital cardiac arrest.
