It has been well established that routine medical preoperative tests (eg, electrocardiograms, radiographic examinations, serum chemical analyses, and blood cell counts) confer no benefit in reducing adverse perioperative medical events during cataract surgery.1 Nonetheless, such testing widely persists,2 and the study by Chen et al3 in this issue of JAMA Ophthalmology demonstrates that the magnitude of health care dollars wasted by this unnecessary testing is even greater than previously thought. The question remains: how do we put an end to a practice that we know is usually unnecessary and therefore wasteful of health care financial resources and the time of patients and physicians?
