Cardiopulmonary resuscitation by medical and surgical house-officers.

In teaching hospitals the responsibility for cardiopulmonary resuscitation usually rests with the house-staff, yet most house-officers receive no formal training in life support. The life-support skills of 45 medical and surgical house-officers in a university teaching hospital were tested by means of simulated cardiac arrests. House-officers were graded on the basis of a performance checklist derived from the standards of the American Heart Association. No house-officer received a pass score in basic life support (BLS). Only 29% could properly compress and ventilate the mannequin. In advanced cardiac life support (ACLS) only one-third could intubate in 35 s or less; only 31%, 40%, and 33% could manage ventricular fibrillation, asystole, and complete heart block, respectively. Some house-officers were unable to operate the defibrillator or assemble resuscitation equipment. Many house-officers displayed helplessness and anxiety during the simulations; fourteen (40%) were prompted to register for additional advanced life-support courses. The performance of medical and surgical house-officers was equal. House-officers who had received prior life-support training performed better in BLS (p less than 0.001) but not in ACLS. It was concluded that (a) most medical and surgical house-officers are not reasonably proficient in BLS and ACLS, and (b) cardiac arrest simulation is a motivating exercise which permits analysis of each house-officer's life-support skills. House-officers should have more training and practice in life support, or they should not have primary responsibility for cardiopulmonary resuscitations.
