Cardiopulmonary resuscitation in intensive care unit and non-intensive care unit patients. Immediate and long-term survival.

OBJECTIVE: To determine the effect of location within the hospital and preexisting electrocardiographic rhythm on the outcome of cardiopulmonary resuscitation, the cardiopulmonary resuscitation records for a 3-year period, including 668 hospitalized patients, were retrospectively reviewed.
RESULTS: Resuscitation was successful in only 12 patients in the intensive care unit (3.3%) and 43 patients not in the intensive care unit (14.0%), 20 of whom were on a telemetry unit. Patients who survived to discharge had similar 1-year survival rates regardless of initial hospital location, although intensive care unit patients had the best 3-year survival rate, and there were no survivors at 3-years in the group that received cardiopulmonary resuscitation in the nonmonitored hospital bed. Survival was best with an initial cardiac rhythm of ventricular tachycardia or fibrillation, but all non-ventricular tachyarrhythmias were associated with survival. Age was not an apparent factor, while survival to hospital discharge favored whites over blacks.
CONCLUSIONS: Futile resuscitative efforts are routinely performed in part because physicians and patients are unaware of outcome results and factors that influence survival. A wider recognition of the limitations of cardiopulmonary resuscitation should lead to advanced directives that reflect this awareness, with substantially more patients choosing not to have cardiopulmonary resuscitation.
