Poor efficacy in this population was the main reason given for policies of never initiating CPR. Specific factors relating to CPR efficacy, such as EMT response time and ease of maintaining trained staff, were not major influences. Almost 30% of facilities offering CPR would perform it in unwitnessed situations, despite unlikely success. Many decisions about CPR may not be fully informed as nurses and physicians are not often assigned to discuss advance directives with residents or surrogates. Utilization of CPR in nursing homes offering resuscitation is low.
