AbstractThe utility of mass screening of preoperative patients has never been demonstrated for the majority of tests. Although screening patients to uncover occult disease appears logical, in reality it has resulted in excessive expenditure of our health care dollars with limited benefit. More than $30 billion is spent annually on preoperative examinations, 60% of which are unnecessary. In addition, iatrogenic injury has resulted from the further evaluation and treatment of false-positive results. A selective utilization of routine examinations can accurately supplement the clinician's evaluation, providing the patient with a complete preoperative assessment. The benefits of selective testing must be balanced against the possible omission of warranted examinations, highlighting the need for a more reliable system for test ordering.
