Evaluation of cardiac arrests managed by paramedics.

The effectiveness of cardiac resuscitations by Cincinnati paramedics was monitored for one year. The outcome of every arrest was assigned to one of four categories: dead on arrival, died in the emergency department, died in the hospital or discharged alive, and each patient was followed until death or discharge from a hospital. Of the 147 people in the study group, 22 left the hospital alive, a long-term success rate of 15%, and another 26 died during hospitalization, 18% of the study population. This data is comparable to success rates reported by other prehospital care systems. Furthermore, this data indicates approximately 15% of people who have cardiac arrests outside of a hospital can survive through prompt intervention by trained personnel.
