Survival after Cardiac Arrest and Changing Task Profile of the Cardiac Arrest Team in a Tertiary Care Center

摘要

Background. The characteristics of in-hospital emergency response systems, survival rates, and variables associated with survival after in-hospital cardiac arrest vary significantly among medical centers worldwide. Aiming to optimize in-hospital emergency response, we performed an analysis of survival after in-hospital cardiopulmonary resuscitation and the task profile of our cardiac arrest team. Methods. In-hospital emergencies handled by the cardiac arrest team in the years 2004 to 2006 were analyzed retrospectively, and patient and event characteristics were tested for their associations with survival after cardiopulmonary resuscitation. The results were compared to a similar prior analysis for the years 1995 to 1997. Results. After cardiopulmonary resuscitation, the survival rate to discharge was 30.2% for the years 2004 to 2006 compared to 25.1% for the years 1995 to 1997 (difference not statistically significant). Survival after one year was 18.5 %. An increasing percentage of emergency calls not corresponding to medical emergencies other than cardiac arrest was observed. Conclusions. The observed survival rates are considerably high to published data. We suggest that for further improvement of in-hospital emergency response systems regular training of all hospital staff members in immediate life support is essential. Furthermore, future training of cardiac arrest team members must include basic emergency response to a variety of medical conditions besides cardiac arrest.
