Objective: To determine the success rates of adult cardiopulmonary resuscitation (CPR) and identify the predictors of successful CPR at the emergency room (ER) at a university-based hospital.

Materials and Methods: Adult patients that experienced cardiac arrest and received CPR at the ER were prospectively observed. The primary outcomes were the rates of return of spontaneous circulation (ROSC), survival to hospital admission, survival to hospital discharge, and discharge with good neurological outcome. The secondary outcome was to determine the predictors of ROSC.

Results: One hundred twenty-nine adult patients were enrolled in the study. The success rates of CPR were ROSC 41.9%, survived to hospital admission 34.1%, survived to hospital discharge 8.5%, and discharged with a good neurologic outcome 3.9%. From multiple logistic regression, the predicting factors for ROSC were cardiac arrest at the ER (odds ratio [OR] 4.89, 95% CI 1.90 to 12.55; p<0.001) and cardiac arrest during morning shift (OR 2.40, 95% CI 1.08 to 5.34; p=0.031).

Conclusion: The success rates of the CPR outcomes were good. Cardiac arrest at the ER and arrest during the daytime were predicting factors for ROSC.
