Answer

The CAPTURE study, a randomized diagnostic trial, compared the efficacy a comprehensive cardiothoracic CT examination in the evaluation of patients presenting to the emergency department with undifferentiated acute chest discomfort or dyspnea. [52] Comprehensive cardiothoracic CT scanning was reasonable, with a similar diagnostic yield to dedicated protocols, but it did not reduce the length of stay, rate of subsequent testing, or costs. The “triple rule out” protocol might be helpful in the evaluation of select patients, but these findings suggest that it should not be routinely used with the expectation that it will improve efficiency or reduce resource use.
