Benefits of training physicians in advanced cardiac life support.

Unexpected cardiopulmonary arrests occur commonly both in the prehospital setting and in the course of hospital care. Survival after prehospital arrest is improved if bystanders and paramedics are trained in basic and advanced cardiac life support. However, within the hospital, the bystanders are the physicians; it is not known if life support training of these hospital-based physician bystanders leads to improved survival. Therefore, we reviewed the outcome of resuscitation attempts in a teaching hospital during two matching six-month periods, before (period 1) and after (period 2) institution of a mandatory course in Advanced Cardiac Life Support (ACLS) for medical houseofficers. It was concluded that survival after inhospital cardiopulmonary arrest is significantly increased if house officers who staff the Code teams are trained in ACLS.
