This is under-scored by the finding that about one-third of cardiac stress tests with imaging are possibly inappropriate, with annual costs of more than $500 million in the US alone (11).
BWH uses the computer software program Precipio to order cardiac stress tests. Using this software, we identified patients that underwent cardiac stress tests ordered by an anesthesiologist at the BWH preoperative evaluation clinic from 12/1/2005 to 5/31/2015.
Overview of the performance of subjects by age group at the 4 mmol lactate threshold and at maximum performance in the bicycle ([p.sub.4mmol-L], [p.sub.max]) in watts, and treadmill ([v.sub.4mmol-L], [v.sub.max]) cardiac stress tests in km/h.

Among the developments and results that Posk shared: beginning in 2009, lab results began to be sent to patients in an automated way, with a built-in three-business-day time delay to allow for clinicians to communicate with patients; in October 2012, the dissemination of results expanded to encompass x-ray results; in April 2013, it was expanded to encompass additional imaging studies, including CT, MR1, bone density, nuclear studies, and ultrasound (radiologists' reports); in June 2013, the release of pathology reports; and in July 2013, the release of procedures, such as cardiac stress tests, colonoscopies, and EGDs.
For example, many doctors routinely order a battery of preoperative tests, including blood analyses, chest X-rays and cardiac stress tests. But when they are done just to "clear'' you for surgery, with little regard to the type of surgery, the kind of anesthesia that will be used or your overall health, they're more likely to cause potentially harmful false alarms than keep you safe, current research shows.
Indeed, financial stress tests - designed to estimate the likelihood of bank failures in the event of bad economic news - are intended to be the equivalent of cardiac stress tests. And, like most cardiac stress tests, the primary aim is to reassure.
